Description

Assembled panel with peripheral connection structure

Technical Field

The invention belongs to the technical field of assembly type buildings, and particularly relates to an assembly type plate with an external connection structure.

Background

The assembled building is formed by transferring a large amount of field operation work in the traditional building mode to a factory, processing and manufacturing building components and accessories (such as floors, wallboards, stairs, balconies and the like) in the factory, transporting to a building construction site, and assembling and installing the building on site in a reliable connection mode. The prefabricated building mainly comprises a prefabricated concrete structure, a steel structure, a modern wood structure building and the like, and is representative of a modern industrial production mode because standardized design, industrial production, assembly construction, informatization management and intelligent application are adopted.

Among them, board construction is a common type of application in fabricated construction. The building is mainly formed by assembling prefabricated large-scale inner and outer wallboards, floor slabs, roof boards and other boards, and is also called a large-board building. The plate building can lighten the structure weight, improve the labor productivity, and enlarge the using area and the shockproof capacity of the building. The inner wall board of the board building is mostly a solid board or a hollow board of reinforced concrete, the outer wall board is mostly a reinforced concrete composite board with a heat insulation layer, and the wall board with an outer facing can also be made of lightweight aggregate concrete, foam concrete or macroporous concrete and the like. Centralized indoor plumbing fittings or box-type toilets and the like are often used for equipment in a building to increase the degree of assembly. The key problem of the plate building is node design, and structural integrity of component connection should be ensured (the connection method between plates mainly comprises welding, bolting and post-cast concrete integral connection). The waterproof structure aims to properly solve the problems of waterproof of the joints of the external wall panels, thermal treatment of building joints and corners, and the like. The main disadvantages of large-slab buildings are that the building modeling and layout are more restricted, and the interior separation of the large-slab buildings with small open-room transverse bearing is lack of flexibility (the interior of the longitudinal wall type, the interior column type and the large-span building slab type can be flexibly separated).

In the existing plate building, the screw is quite common in a connection mode, but because screw connecting pieces are arranged inside the plate, when the plate is formed into a complete building structure, whether the connection is stable or not cannot be directly detected from the outside. The connection mode cannot pass the acceptance successfully according to the existing acceptance specification of the building industry. Meanwhile, if the joint is maintained in the later period, special inspection or investigation instruments are needed to be adopted for checking the joint, and potential hazards possibly existing cannot be found in time.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a wall board structure, which is different from the existing built-in connecting piece, not only can realize better connecting and fixing effects, but also can directly check whether the connecting structure is stable from the outside, and can smoothly pass acceptance, thereby providing convenience for subsequent maintenance work.

The technical scheme adopted by the invention is as follows:

in a first aspect, an assembled panel with a peripheral connection structure is disclosed, wherein the assembled panel is connected and fixed with each other to form a wall body, the wall body is partitioned to form a plurality of spaces, or the wall body is surrounded inside to form an independent area, the assembled panel comprises:

the plate body is preformed by a die, and a connecting groove is arranged outside the plate body;

The connecting piece is used for connecting and fixing at least two plate bodies;

The connecting piece comprises a rod piece arranged in the connecting groove, and further comprises a locking piece, wherein when the rod piece is arranged in the connecting groove and one end of the rod piece is fixed, the plate body is tensioned and fixed by arranging the locking piece on the other side of the plate body.

Firstly, the plate body is a prefabricated part, and the connecting groove arranged outside is an empty groove formed by blocking pouring by a space occupying piece in the die. Generally, a plurality of groups of connecting grooves are symmetrically arranged on two large-area surfaces of the plate body, and the connecting grooves are clamped and tensioned from two sides, so that good connection stability is formed.

However, it should be noted that the number and the arrangement positions are not limited in the claims, and the rod member is arranged only on one side of the plate body, so long as the specific structure and the connection mode are optimized, and the fixing effect can be achieved, the scheme of arranging the rod member on one side or both sides is within the protection scope of the invention.

The plate body is connected with the plate body to form a wall body, and the plate body at the end part of the wall body is connected with other plate bodies or fixed structures through connecting pieces. If connected with other plate bodies, the plate body forms a corner and forms an independent room. The fixing structure is generally a building main body structure formed by casting, the rod members are inserted into the fixing structure, and the plate body is propped against the fixing structure through the locking members after the plate body is sequentially arranged along the rod members. And then sequentially fixing the plate bodies, and continuously fixing each plate body or a plurality of plate bodies by using a locking piece after connecting.

The locking member is sleeved on the rod, the plate body is pushed to one side by external force and kept stable under the continuous action of the external force, and the locking member is operated to abut against one side of the plate body and form a fixed relation with the rod. Then the external force is removed, and the plate body is locked and fixed.

It is also worth noting that by bar is meant a member having a longitudinal (length) dimension that is substantially greater than a transverse (perpendicular to the length) dimension, and that members having a length that is greater than a dimension perpendicular to the length are considered to be within this range. Because the plates are fixedly connected with each other and are tensioned and fixed through the rod piece and the locking piece, the soft steel cable can be also suitable for fixing the structure.

With reference to the first aspect, the present invention provides a first implementation manner of the first aspect, where the two sides of the plate body are provided with multiple groups of corresponding connection grooves;

The locking parts are simultaneously fixed on two rod pieces which are arranged on different surfaces and are positioned on the same horizontal plane.

It should be noted that the plate body has a certain thickness, and two opposite large-area surfaces are arranged on two sides of the plate body, and the multiple groups of the connecting grooves are arranged on each surface in a parallel manner, and the connecting grooves are arranged along the width direction of the connecting grooves and have the same size. The connecting grooves on the two sides are correspondingly arranged, namely the same number and the same arrangement height, the height is the horizontal height when the plate body stands on the ground, and meanwhile, the connecting grooves on the surfaces of the two sides can be staggered, the same interval is reserved between the connecting grooves on the surfaces of the two sides, and the height difference is reserved between the corresponding connecting grooves on the two sides.

With reference to the first embodiment of the first aspect, the present invention provides a second implementation manner of the first aspect, where the boards are interconnected to form a wall, and multiple groups of walls are surrounded to form a building;

number of connecting grooves on outer side of plate body is greater than the number of the inner connecting grooves.

It should be noted that if the panels are surrounded to form a building, the joints between each wall are provided with appropriate bridging members, so that the external and internal rods are individually connected to form an annular fixing member. The external rod piece is used as a main bearing structure, so that the material can be saved.

With reference to the first real-time manner of the first aspect, the present invention provides a third implementation manner of the first aspect, wherein the locking member is provided with a locking screw;

The locking screw is inserted into the locking piece in a direction perpendicular to the axis of the rod piece and abuts against the surface of the rod piece at the end part to be limited and fixed.

It is worth to say that the locking member is provided with a screw hole, and the axis of the screw hole is perpendicular to the axis of the rod passing through the locking member. The rod piece penetrates through the plate body from the outer side, so that the plate bodies are connected and limited, and a plurality of locking pieces are arranged on the same side of each plate body to fix the plate bodies, so that the plate bodies in the same row are mutually abutted and fixed. The locking piece is detachably connected with the rod piece in a limiting mode, and particularly limiting is achieved through fixation of the locking screw rod. The principle is that the end of the locking screw rod is in relatively high static friction with the rod surface by reciprocating in the direction perpendicular to the axis of the rod and forming relatively high downward pressure on the surface of the rod contacted with the end of the locking screw rod.

And the end part of the locking screw is provided with an arc-shaped groove which can be conformal with the surface of the rod piece, so that the contact area of the locking screw is increased to form a sufficient lower contact surface, and the problem that the friction force is too concentrated to cause the damage of the end surface material of the rod piece or the locking screw affects the limiting effect can be avoided.

With reference to the first embodiment of the first aspect, the present invention provides a fourth implementation manner of the first aspect, the rod is in a screw structure, and the end of the locking screw is in threaded fit connection with the surface of the screw.

The static friction of the rod and the locking screw is mainly related to the pressure and the surface roughness, the pressure is related to the set thread density, and the surface roughness is determined by the special contact surface shape. The rod piece is of a long screw rod structure, the surface of the rod piece is provided with equidistant threads, tooth-shaped lines are arranged on the end face of the locking screw rod and can be matched with the threads to form a certain degree of engagement, and a good limiting effect is achieved by amplifying static friction force.

With reference to the first embodiment of the first aspect, the present invention provides a fifth implementation manner of the first aspect, where the locking member is provided with a through slot, and an opening of the through slot corresponds to the rod member, so that the locking member is sleeved on the rod member in a direction perpendicular to an axis direction of the rod member.

It should be noted that, in the actual installation process, since the rod member has a certain length, a single rod member or at least a plurality of plate bodies are connected. If the through holes of the locking pieces are not opened laterally when the locking pieces are installed, the number of the locking pieces is calculated before the locking pieces are installed, and the locking pieces penetrate from the end parts of the rod pieces and move to one side of the corresponding plate body in sequence to be positioned. The through groove structure can directly insert the locking piece on the rod piece from the side direction after the plate body is positioned, and then the locking piece is fixed by the locking screw.

With reference to the third embodiment of the first aspect, the present invention provides a sixth implementation manner of the first aspect, wherein a sink groove is formed on a corresponding side surface of the thickness of the plate body, and the locking member is inserted into the sink groove when the corresponding plate body is fixed.

With reference to the third embodiment of the first aspect, the present invention provides a seventh implementation manner of the first aspect, where the connecting piece further includes a fastener, where the fastener has a pressing structure, and the fastener is sleeved on the rod and forms a fixed connection with the rod through the pressing structure;

The fastener also has a push rod which is operated to enable the same side locking member to abut the surface of the plate body when the fastener is secured.

With reference to the seventh embodiment of the first aspect, the present invention provides an eighth embodiment of the first aspect, wherein the fastener is provided with a through hole through which the rod passes, and a channel extending outwards in a direction perpendicular to the axis of the through hole is provided on an inner wall of one side of the through hole, and the rod can laterally enter the through hole from the channel.

With reference to the first embodiment of the first aspect, the present invention provides a ninth implementation manner of the first aspect, where the locking member has a locking structure, and the locking structure contacts with the surface of the rod member and is pressed to form a fixing effect;

The operation end of the locking structure is arranged on the surface of one side of the rod piece penetrating out of the locking piece.

The beneficial effects of the invention are as follows:

(1) According to the invention, the plurality of plate bodies are connected through the external rod pieces to form the wall body, and the locking piece is used for quick positioning, so that the original built-in connecting piece can be directly visible outside, especially the connecting part can be used for directly acquiring the connecting state from outside, and the requirements of acceptance and subsequent maintenance can be met;

(2) The locking piece is quickly pre-positioned by the fastener matched with the locking piece, compared with the existing connecting structure, the locking piece can be quickly assembled, compared with the mode of directly screwing the bolt for connection, the mode of forming a fixing effect by laterally extruding the locking bolt is more convenient, and the limiting effect can be improved as much as possible by the toothed structure design of the end part.

Example 1:

the embodiment discloses panel structure mainly is applied in assembled building, forms the wall through connecting a plurality of plate body 2 parallel, can realize the subregion interval to the inner space through quick assembly in current building body structure inside.

Specifically, as shown in fig. 1 and 2, the plate mainly comprises two parts, wherein the middle part is provided with four plate bodies 2 which are connected with each other, and the two side end parts are provided with fixing columns 1 for fixing. The fixing columns 1 are building main bodies which are originally cast and formed, and the plate body 2 is arranged between the two fixing columns 1 to form a partition.

It should be noted that, the drawings are only for illustration, and the space between the fixing columns 1 in the actual construction process is far greater than the width of the four standard boards 2.

Unlike the prior art, the inner and outer surfaces of four plates are provided with five rods 5, and each plate is provided with a through connecting groove 3, and the connecting grooves 3 on the surfaces of the plates are aligned and communicated after the plates are connected. During assembly, one end of the rod piece 5 is fixed in one side connecting column through an expansion bolt, and is directly fixed in the left side fixing column 1 in the drawing. And each plate body 2 is arranged, five locking pieces 4 are arranged on the right side of the plate body 2 for tensioning and fixing.

Because the fixed column 1 at the left end is of a fixed structure, after the rod piece 5 is fixed, the adjacent plate body 2 is directly pushed to one side of the fixed column 1 by an engineering tool from the right side, and five locking pieces 4 are arranged on the right end face of the plate body 2 to be positioned when the left end face of the plate body 2 is completely abutted against the surface of the fixed column 1. The locking piece 4 is propped against the right side of the plate body 2 through operation, and then the locking structure arranged in the locking piece 4 presses the surface of the rod piece 5, so that a limiting relationship is formed between the locking piece 4 and the rod piece 5, and at the moment, the external force is removed and the lower plate body 2 is installed.

In fig. 3, it can be seen that the end faces of the two thicknesses of the plate body 2 are provided with concave-convex structures 2.1 which are matched and inserted, the left side of the plate body 2 is provided with convex strip structures, the right side of the plate body 2 is provided with groove structures, and when the adjacent plate body 2 is propped against and is tensioned through the rod piece 5 and the locking piece 4, the convex strips and the grooves are combined to prevent the side from applying external force to crack.

Whereas the surface of the plate body 2 in fig. 3 is provided with square grooves 6 in the vertical direction, which square grooves 6 are intended to receive lines for the purpose of forming a building interior wiring arrangement.

It should be noted that, the board body 2 in this embodiment is poured and formed in advance by a mold, and then transported to the installation site for assembly according to the requirement. The notch structures on the surfaces are formed through a die, and are shielded after assembly by coating cement mortar or a veneer.

Example 2:

In this embodiment, the optimization and limitation are performed on the basis of the above embodiment 1, as shown in fig. 3 and fig. 4, as the inside and outside of the single plate body 2 are respectively provided with the corresponding connecting grooves 3, and the connecting grooves 3 are correspondingly arranged on the same horizontal plane, two total rod members 5 passing through the single locking member 4 are provided.

In this embodiment, for installing the locking member 4, a fastener 8 is provided on the rod 5, and can be fixed on the rod 5, and the fastener 8 has a push rod 10 for pushing the locking member 4 to be attached to the plate 2. The plate body 2 is equipped with fastener 8 one side and corresponds to be equipped with heavy groove 2.2 structure, and this heavy groove 2.2 structure is for running through the setting in length direction (i.e. the thickness direction of plate body 2), and heavy groove 2.2 cross-section is rectangular structure, corresponds with retaining member 4. It can be seen that the locking element 4 is provided with two through holes for the rod 5 to pass through.

In order to fix the locking member 4 and the rod member 5, fastening screw holes 15 are formed on two sides of the locking member 4, and the fastening screw holes 15 are communicated with the through holes where the rod member 5 is located. A locking bolt is arranged in the fastening screw hole 15, and the end part of the locking bolt is propped against the surface of the rod piece 5 by screwing the locking bolt, so that the fixing effect is achieved.

It should be noted that the lock bolt is shown only in the state of being inserted into the fastening screw hole 15, and the lock bolt in this embodiment includes two parts, in which one abutment 13 is provided at an end portion. The supporting block 13 is made of plastic material and is rotationally connected with the main structure of the locking bolt. The abutment 13 can move linearly in the fastening screw hole 15 along with the screwing of the locking bolt, and the end of the abutment is designed to be a cambered surface, so that the abutment has a larger contact area on the surface of the abutment rod piece 5.

The arc surface 16.1 of the abutment 13 is provided with concave-convex lines, and the surface of the contact rod piece 5 is deformed by the extrusion of the locking bolt, so that a large static friction force is obtained to limit the movement of the locking piece 4. During installation, the locking piece 4 needs to be moved into the sinking tank 2.2, and then the locking piece 4 is pushed by external engineering equipment to be extruded into the sinking tank 2.2, or the rod piece 5 is continuously pulled outwards. Then the external force is kept, the locking bolts are inserted from two sides to be locked, and finally the external force is removed to reach a stable state.

Because this wall body outside can set up decorative board and heat preservation, the spread groove 3 that is equipped with then can be fixed the back at member 5 through filling cement mortar or other gypsum and shutoff, perhaps directly adopts panel to shelter from outside to be equipped with the opening in key junction, look over when supplying later maintenance.

In this embodiment, the plate body 2 is directly connected to the side of the plate body 2, so that the depth of the sink 2.2 is slightly greater than the width of the lock 4 in order to prevent the lock 4 from affecting the connection stability, and the lock 4 can be completely immersed in the sink 2.2 when being fixed.

Example 3:

This embodiment is optimally defined based on embodiment 1 described above, and as shown in fig. 5 to 9, a structure of the locking member 4 is shown, and unlike embodiment 2 described above, mainly the insertion direction of the locking screw 7 and the fixing manner of the locking screw 7 are adjusted, thereby improving stability.

The lock 4 of the above embodiment 2 is simple in structure and convenient to operate, and the lock screw 7 is provided so as to be inserted in opposite directions from both sides in the longitudinal direction for convenience of operation. However, since the width of the whole locking member 4 is not greater than the width of the plate body 2, and the depth of the connecting groove 3 is smaller than the thickness of the plate body 2, the distance between the two rod members 5 passing through the locking member 4 cannot be reduced, and the stroke of the locking screw 7 is shorter.

In this embodiment, the plurality of plate bodies 2 are fixedly connected through the inner and outer five rods 5, and the right side of the plate body 2 is provided with a sinking groove 2.2 for fixing the locking member 4. The locking piece 4 is internally provided with a through hole and a screw hole, and an expanding cavity is arranged at the end part of the screw hole, and a compression block 12 is arranged in the expanding cavity. The compressing block 12 can slide in the expanding cavity, the sliding direction is vertical to the axis of the rod piece 5, and the rod piece 5 is laterally compressed and fixed through the compressing block 12. And the moving direction of the locking bolt is perpendicular to the moving direction of the compressing block 12, and the transmission is realized by matching the abutting block 13 arranged at the end part of the locking bolt with the compressing block 12.

Specifically, the abutment 13 is configured to be slidable in the expansion chamber as well, but unlike the above-described embodiment 2, the abutment 13 is limited to the expansion chamber and is not connected to the lock screw 7 as a separate structure. But concave spherical surface is formed on the contact surface with the locking screw rod 7, and is propped and pushed by the convex spherical surface at the end part of the locking screw rod 7. Because the locking member 4 is generally kept in an initial state for a long time after being fixed in consideration of a low frequency of attachment and detachment, no return spring structure is provided in the expansion chamber.

In order to realize transmission between the abutting block 13 and the compressing block 12, the contact surfaces of the abutting block 13 and the compressing block 12 are all provided with inclined structures. When the pressing block 13 is pushed by the locking screw 7, the pressing block 13 can transmit the pushing force in the vertical direction to the pressing block 12 through the inclined plane component force. Because the advancing direction of the locking screw 7 is along the axial direction of the rod piece 5, the locking screw is not limited by the length of the locking piece 4, and the fixing effect can be prevented from being influenced by the abutting block 13 during fixing by arranging longer and denser threads.

Also disclosed in this embodiment is a fastener 8 for securing with the locking member 4, as shown in the enlarged partial view of fig. 6, the fastener 8 being also fitted to the rod 5, the fastener 8 being in a door-like configuration in plan view from above. The fastening member 8 is also provided with a fastening through hole 18 for the rod 5 to pass through, and a passage communicating with the fastening through hole 18 is also provided at the lower portion. The channel is actually an opening of the fastening through hole 18 at the lower part, so that the rod piece 5 can be directly inserted into the fastening through hole 18 from the lower end, the mode that the fastening piece 8 needs to penetrate from the end part of the rod piece 5 when being installed is avoided, and the assembly efficiency is improved.

The fastening element 8 likewise has a similar clamping structure to a locking bolt, namely a fastening screw 9 in the illustration. The fastening screw 9 is also of screw structure, but since the whole width is not considered, a two-side insertion mode can be adopted, and protruding lengthening parts are arranged at corresponding positions of two sides to increase the stroke of the screw.

The fastener 8 is also provided with a push rod 10, the push rod 10 is in threaded fit with the fastener 8, the end part of the push rod 10 is aligned with the surface of the adjacent locking piece 4, and after the push rod 10 is screwed, the push rod 10 can prop against the locking piece 4 to press the locking piece towards the sinking groove 2.2 so as to realize compression.

The concrete principle is that firstly, the locking piece 4 is arranged in the sinking groove 2.2, then the fastening piece 8 is moved to the corresponding position, and the fastening piece 8 is fixed on the rod piece 5 by operating the compression structures at the two sides. Then the push rod 10 is screwed again, the locking piece 4 is fixed in the sinking groove 2.2 through the push rod 10, at the moment, the locking bolt is operated again to fix and limit, and finally the fastener 8 is disassembled to start to install the other locking piece 4.

Example 4:

As shown in fig. 10-12, the present embodiment also discloses a connection member for forming a wall body by the panel body 2 and the connection panel body 2.

Specifically, the plate is formed by transversely attaching and splicing a plurality of plate bodies 2, the specific structure of a single plate body 2 is shown in the figure, and the plate body is formed by prefabricating and pouring through a die. It can be seen that the plate body 2 is a rectangular plate with longer vertical direction, and staggered rectangular grooves are formed inside and outside the vertical height direction and are used for arranging lines, so that wires can be hidden in the plate body 2 after the whole wall surface is formed.

Five equally-spaced and parallel connecting grooves 3 are respectively arranged on the inner side and the outer side of the plate body 2 in the horizontal direction, the depth of each connecting groove 3 is larger than that of each rectangular groove, and the inner bottom is an arc-shaped bottom surface. When the plate bodies 2 are attached to each other, the connecting grooves 3 are mutually communicated to form a through groove body structure, and the same rod piece 5 is arranged in the connecting grooves 3 of the plurality of plate bodies 2 for connection.

It can be seen that, for demonstration, two rod pieces 5 are arranged in the connecting groove 3 at the bottommost part, a sinking groove 2.2 is arranged on the right side of the plate body 2, a locking piece 4 is arranged in the sinking groove 2.2, and the two rod pieces 5 symmetrically penetrate through the locking piece 4 and are fixed and tensioned through the locking piece 4.

In fig. 12, it can be seen that the locking element 4 has two locking through holes 11 for the passage of the rod 5. The lower part of the locking through hole 11 is hollowed out to form an opening, and the width of the opening is larger than or equal to the diameter of the cross section of the locking through hole 11. Because the original locking through hole 11 structural design makes retaining member 4 need penetrate from member 5 tip when the installation and fixes, then the opening that is equipped with makes member 5 can follow lower part perpendicular entering locking through hole 11 in, the installation of being convenient for. The sinking groove 2.2 arranged on the side surface of the plate body 2 can limit the locking piece 4 to prevent the locking piece from sliding out of the upper part and losing connection with the rod piece 5.

Two dovetail grooves which are in the same direction with the axis direction of the through hole are arranged on the inner wall of the opening, and the insert block 16 is connected through the dovetail grooves in a matching way. The insert block 16 can be inserted along the axial direction of the locking through hole 11, two inserts corresponding to the dovetail grooves are arranged on the insert block 16, a penetrating fixing hole is arranged in each insert, and the insert block 16 is fixed on the locking piece 4 through an inserting bolt.

It can be seen that the insert 16 has an arcuate surface 16.1 above it, which is formed by the blocking and bounding of the opening of the locking through hole 11 of the locking element 4. A progressively larger projection is provided at the outer end of the arcuate surface 16.1, the projection being of deformable rubber material and projecting progressively outwardly from the midline of the insert 16. That is, when the rod 5 is disposed in the locking through hole 11, the insert 16 is inserted into the locking member 4, and when the protruding structure abuts against the rod 5, deformation is generated and abuts against the rod 5. If the deformation amplitude of the protruding structure exceeds 50% after the insert block 16 is completely inserted and fixed, the rod piece 5 can be subjected to lateral larger extrusion force, and a proper concave-convex surface structure can be arranged, so that the locking piece 4 has a good limiting effect and is prevented from being frustrated in use.

In this embodiment, a special fastening tool, fastening means 8, is also included. The fastener 8 comprises two mutually buckled parts, namely an upper fastener and a lower fastener. The upper fastener is of a main structure, the end part of the upper fastener is provided with a fastening screw hole 15, and the fastening screw hole 15 is used for being matched with the structure of the push rod 10, so that the push rod 10 can rotate to push the locking block to prop against the plate body 2.

Unlike the above embodiment 3, the fastening member 8 in this embodiment is directly fastened to the surface of the rod body to form a clamped state, and the upper fastening member and the lower fastening member are fastened by bolts, so as to be fastened to the rod 5 from the side without penetrating from the end of the rod 5. Wherein, be equipped with the hold-down hole 14 on last fastener and the lower fastener, be convenient for the bolt to penetrate and fix.

The specific operation principle and steps are the same as those of the above-described embodiment 3, and will not be described in detail here.

Example 5:

this embodiment optimizes the locking member 4 on the basis of embodiment 1 described above, wherein, as shown in fig. 13 and 14, the rod member 5 is provided with a plurality of thread segments, the pitch of which is related to the width of the plate body 2, and the center-to-center distance of the thread segments is generally equal to the width of the plate body 2. During assembly, the end part of the rod piece 5 is fixed on the fixed column 1 to a certain depth, so that the rod piece 5 has thread sections at fixed positions of the locking piece 4 after each plate body 2 is fixed. At the moment, the locking member 4 is fixed in the sinking groove of the plate body 2 by the locking bolt 19, so that the assembly efficiency is improved, and the structure is simple and the cost is lower.

It should also be noted that, not shown in the figures, the locking through hole 11 side of the locking member 4 is also provided with an opening, and the length of the opening is the same as that of the locking through hole 11, so that the rod 5 can directly enter the locking through hole 11 from the side.

The invention is not limited to the alternative embodiments described above, but any person may derive other various forms of products in the light of the present invention. The above detailed description should not be construed as limiting the scope of the invention, which is defined in the claims and the description may be used to interpret the claims.
