Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork for construction, and in particular, a formwork is unitized by integrally standardizing a form panel and a frame skeleton, facilitating assembly and improving work efficiency, and widely applicable. It relates to a building formwork that can reduce costs.

[0002]

2. Description of the Related Art Floor plans of general high-rise apartment houses and high-rise office buildings are designed to be almost constant in most cases in consideration of productivity and cost. In particular, in recent years, high-rise apartment complexes built by public bodies have been constructed on a large scale under uniform standards, so the formwork has also been used according to changes in the construction method. The wood formwork has evolved into the current metal foam formwork.

As shown in FIG. 7, this metal foam panel is composed of a steel panel 100, a frame 120 and a reinforcing beam 130. Framework 120 and panel 10
In order to prevent deformation of the panel 100 by widening the contact area with 0, as shown in FIGS. 8 and 9, a large number of support beams 140 are provided between the frame 120 and the panel 100. Further, as shown in FIG. 7, each panel 10 arranged on both front and back surfaces of the concrete wall to be formed.
Through holes 150 are provided at positions corresponding to each other, and rods are installed between both panels 100 which are assembled and face each other on the front and back sides, and concrete formed between both panels 100 having a thickness of a concrete wall. The width of the mortar driving space is kept constant so that the opposing panel 100 does not bend or bulge due to the pressure of the concrete mortar poured into the concrete mortar driving space.

[0004]

However, the conventional metal foam panel described above has the following drawbacks. When assembling a metal foam panel,
The framework, the support beams and the reinforcing beams are combined together. However, since the structure of the framework is generally complicated, the framework is first assembled, and then the supporting beams and the panels and the reinforcing beams are combined. Therefore, the main structure composed of the panel, the frame, the support beam and the reinforcing beam is, so to speak, four members, but since the structure of the frame is complicated, the whole assembling work is considerably troublesome.

When the number of floors is large, it is usually advantageous to standardize the floor plan and make it constant. However, in high-rise buildings, the cross-sectional area of columns increases stepwise every 4th and 5th floor in response to an increase in load. Therefore, the wall area is gradually reduced accordingly.
When the size of the building varies in this way, the panel is cut or the area is adjusted by a seam method, but this panel can be used only on a fixed number of floors of the same building. The size may not fit when used in the next step. In this case, it is necessary to adjust the area of the panel again by cutting or piecing. Moreover, this frequency is quite high. The change in the formwork dimension due to the reduction of the partition during this time is much smaller than the original panel width dimension, so the panel is cut into small pieces and welded. Is a non-negligible amount, which takes time and is costly.

The position where the panel is cut is not constant, and the relative position of the through hole suitable for erection of the rod may be cut in the previous step. In order to prevent the concrete mortar from leaking from the through hole where the rod was previously inserted,
It is very inconvenient because a through hole having a hole diameter of about 25 mm must be closed.

The metal foam formwork panel of this type generally has a relatively large area, and in consideration of the cost when it has to be cut, taking the room layout design shown in FIG. It is very suitable for assembling the form of the partition wall 210, but it has a wall 230 of the corridor 220 and a pipe shaft 240 with a width of only 740 mm.
When used for, etc., the panels cannot be combined fundamentally. Further, in this case, even if a large-area panel is cut and assembled, it is more uneconomical than the conventional wood panel in terms of cost. Therefore, the current metal foam panel is used only when assembling the outer wall of each floor or the partition formwork of the hall, and the floor plan is directly partitioned by general bricks or light partition materials. The effect of using the panel is greatly discounted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems in the conventional formwork panel for construction, and has as its object to provide a formwork for construction which has a simple structure, is easy to assemble and disassemble, and has a wide range of application. is there.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the drawings. As shown in FIG. 1, a building formwork according to a first embodiment of the present invention includes a plurality of main frames 1 and a plurality of reinforcing beam units 2 integrally formed by welding.
It is a combination of.

The main frame 1 is made of metal and, as shown in FIG. 2, is a panel portion 11 which serves as a barrier surface for blocking concrete mortar, and is orthogonal to the panel portion 11 on both side edges on the back side of the panel portion 11. Then, a side plate 12 is provided which extends rearward and connects adjacent main frames 1 to each other. A fixing portion 13 is welded to each side of the both side plates 12 opposite to the side connected to the panel 11. Further, the main frame 1 may be provided with the joining holes 14 at the same height position on both side plates 12 as the specific main frame 15.

In this embodiment, the width of the main frame 1 is 100 m.
m, 120mm, 140mm, 160mm, 180mm, and 200m
6 standard sizes of m are set. However, main frame 1
The width is not limited to this, and may be a combination of appropriate dimensions. The height of the main frame 1 is formed in a unified size that is slightly higher than the normal height of each floor in a general building. An appropriate number of main frames 1 are selected from a large number of main frames 1 and through holes 15 for hanging a retaining rod are formed in each of the main frames 1 in the same manner as in the conventional metal foam panel, depending on the dimensions of the wall to be formed. A connected body (formwork panel set 1 ') of the main frame 1 having dimensions is formed.

The reinforcing beam unit 2 is a rectangular parallelepiped box body, and is provided with a base body 21, a pair of end faces 22 and 22 and a pair of side faces 23 and 23 that face each other on the peripheral wall of the base body 21.
The end face 22 and the side face 23 have joint holes 24, 2 respectively.
5 is provided. The length of each reinforcing beam unit 2 is formed to a standard size similar to the various width sizes of the main frame 1.

When assembling the building formwork according to this first embodiment, first, the wall width of the building is measured, and then the number of main frames 1 of different width sizes which are appropriately arranged according to the width. Then, as shown in FIG. 3, the panel portion 1 of the main frame 1 is calculated.
1 are arranged so as to face the concrete mortar driving section. Next, the main frames 1 adjacent to each other are connected and fixed to each other by the screw member 31 inserted through the joint hole 14, and the screw contact member 32 is inserted into the metal washer 33, and one end of the metal washer 33 is fixed to the fixing portion 13. The metal washer 33 and the reinforcing beam unit 2 are kept substantially parallel by pressing and abutting the other end of the curved metal washer 33 to the reinforcing beam unit 2. In this state, the tip of the screw member 32 is inserted into the joint hole 25 of the side surface 23 of the reinforcing beam unit 2 and screwed to fix the reinforcing beam unit 2 to the main frame 1. When the side plate 12 of the main frame 1 has a sufficient thickness, the metal washer 33 and the fixing portion 13 are not used, and the screw member is directly inserted from the joint hole 25 of the side surface 23 of the reinforcing beam unit 2. It may be screwed and fixed so as to be inserted and locked to the side plate 12 of the main frame 1. Then, the reinforcing beam units 2 adjacent to each other are inserted into the joint holes 24 of the respective end faces 22, and the screw members 34 are inserted.
Screw in and connect and fix.

As shown in FIG. 4, when the building formwork according to the first embodiment is used, the two assembled formwork panel sets are separated by a gap distance that maintains the thickness of the building. Through holes 1 of specific main frames 1 that are attached so that their panel portions 11 face each other and that face each other of the pair of mold panel sets.
5, both ends of the retaining rod 35 are screwed by the screwing members 36 to firmly hold the distance between the two formwork panel sets, and the two formwork panel sets project from the lateral pressure of the concrete mortar driven into. Prevent it from being stretched.

The building formwork according to the first embodiment of the present invention has the following advantages as compared with the conventional building formwork of this type. Since the main frame 1 is a single panel unit member, it can be combined with the reinforcing beam unit 2 to form a formwork panel set having an appropriate size, and the main frame 1 and the reinforcing beam can be configured as a whole. It only includes the two main parts of the unit 2. At this point, the panel and frame are manufactured separately and then combined, and the complex frame is assembled and the frame is provided with support beams to increase the contact area between the panel and the frame, and then combined with the panel. As compared with the conventional construction formwork consisting of four main members, it has a structure for attaching a reinforced beam, and it is possible to reliably reduce the manufacturing cost and the assembly time, and it is convenient.

As described above, the main frame 1 of the first embodiment is
It is standardized as a small unit, and the width of the panel 11 is 100mm, 120mm, 140mm, 160mm, 18
Since there are 6 standard sizes of 0 mm and 200 mm, 10
Main frame with 4 different standard sizes if the width is 0 mm or more 1
By assembling and arranging in (1), it is possible to construct a formwork panel set having dimensions other than the above-mentioned 6 standard sizes. For example, when the width of the mold panel set is 220 mm, one main frame 1 of 100 mm size and one main frame 1 of 120 mm size may be combined. When the width of the formwork panel set is 240 mm, two 120 mm size mains may be combined. When the width of the mold panel set is 260 mm, one main frame 1 of 100 mm size and one main frame 1 of 160 mm size may be combined. When the width of the formwork panel set is 280 mm,
Two 140 mm size main frames 1 may be combined, or one 120 mm main frame 1 and one 160 mm main frame 1 may be combined. When the width of the formwork panel set is 300 mm, either one 140 mm size main frame 1 and one 160 mm size main frame 1 can be combined, or one 120 mm main frame 1 and one The 180 mm main frame 1 may be combined.

Thus, in the building formwork of the first embodiment,
In other words, by combining the formwork widths required by the building block method, it is possible to obtain a formwork panel set with a desired width dimension.If the formwork panel set is used in a process with slightly different width dimensions, a new There is no need to make panels, cut panels that have been used up to now, or make small panels and add them. For example, the wall with the front floor is 360
When the width is 0 mm, it is sufficient to use 20 main frames 1 of 180 mm size, but when the wall surface became 3620 mm wide due to the change in the cross-sectional area of the pillar on the following floor, the main frame that had been used until then One of the frames 1 180mm size 200
You can replace it with one of the size. As described above, in the first embodiment, the main frame 1 can be applied to a building of any width size without cutting the main frame 1 and has a width of 100 mm or more. There is no need to worry about the construction method, such as whether to build another panel from the difference, to brick the building, or to partition with a light partition material.

Since the through hole 15 is bored in a specific main frame 1 of the main frames 1 constituting the form panel unit, the surface area and thickness of the concrete mortar driving portion of the building and the form panel set are received. The distance between the through holes 15 and the number of holes can be determined according to the lateral pressure of the mortar, and when assembling the form panel set, by combining the specific main frames 1 having the through holes 15 at appropriate intervals, The specific main frame 1 is also attached to each part of the other formwork panel set facing the specific main frame 1.
If both ends of the rod 35 are screwed into the through holes 15 respectively, it is possible to fix the concrete mortar fixed by the lateral pressure of the concrete mortar into which the distance between the two mold panel sets is driven.

The standardized minimum width size of the main frame 1 is 100 mm, and therefore it can be used without problems in a frame assembly such as a wall with a narrow corridor or a pipe shaft having a width of only 740 mm, and a panel. Since it is not necessary to cut, it is possible to construct not only the outer wall but also other partition walls at the same time during the work, and the width size of the main frame 1 corresponds to special demands other than the above 6 types. The main frame 1 having a larger width or a smaller width may be manufactured.

FIG. 5 shows a second embodiment of the present invention. In the second embodiment, the reinforcing beam unit 4 has the side surface 4
2, 42 are integrally connected on the base 41 and have a hollow rectangular shape. Further, the concave portions 4 are formed on the upper and lower edges near the end surface 43 of the side surface 42.
4 is provided. A joint hole 45 is formed between each recess 44 and the end face 43 closest to the recess 44. Furthermore,
A plurality of joint holes 46 are provided on each side surface 42. At the time of assembly, the reinforcing unit 4 is screwed to the main frame 1 by a screwing member that is inserted into the joint hole 46 of the side surface 42, and at the same time, is screwed into the joint hole 45 that is formed between the concave portion 44 and the end face 43. The reinforcing beam unit 4 is attached to the formwork panel set by screwing the fastening member into the joint hole 45 of the adjacent reinforcing beam unit 4.
Assemble. The other structure and operation of the second embodiment are similar to those of the above-mentioned first embodiment.

FIG. 6 shows a third embodiment of the present invention. In the third embodiment, the main frame 5 is integrally formed by extrusion molding lightweight aluminum or aluminum alloy. Further, the main frame 5 may be integrally molded with a non-metallic material having suitable strength (for example, plastic steel = Plastic Steel). Further, the main frame 5 is formed with a smooth panel portion 51 on one surface thereof, and side plates 52 and 53 for joining both main frames 5 which are adjacent to each other by extending at right angles on both sides of the back surface of the panel portion 51. Is provided. On one side plate 52, a convex edge 54 protruding outward is formed. The other side plate 53
The concave edge 5 having a complementary shape corresponding to the convex edge 54.
5 is provided. In addition, the convex edge 54 and the concave edge 55,
Joining holes 56 and 57 are formed respectively, and the both side plates 5 are formed.
The main frames 5 are formed into a standardized small panel unit by forming inward fixing portions 58 and 59 on the side edges of the 2, 53 away from the panel portion 51, respectively. When used, as in the first embodiment, a form panel is formed by connecting an appropriate number of main frames 5 of an appropriate size according to the width of the form to be assembled and further attaching a reinforcing beam unit. Assembly of the set is completed.

In the present invention, when the main frame is an aluminum product, when the assembled and finished panel parts are painted with lacquer and the mold is disassembled, the partially dried and solidified concrete is an aluminum panel. To adhere to. on the other hand,
Although paints may adhere to the surface of the concrete that has been cured and solidified after the formwork is dismantled, epoxy resin should be used in each experiment rather than the experiment if it adversely affects the painting of lacquer or the application of tiles and wallpaper to the building. It has been found that there is an effect that the surface of the building can be kept clean if it is painted on the panel part, and if epoxy resin is painted, it can be used for painting lacquer or for tiles on the wall surface of the building. It has no effect.

[0032]

As is apparent from the above description, in the building formwork according to the present invention, the panel, the frame, the reinforcing beam, the supporting beam and the like in this main formwork of the prior art exist separately. Unlike the complicated structure, it is possible to assemble a strong formwork in the building block method only with the main frame and the reinforcing beam unit, and it can be reused for different processes, and it is narrower than the formwork of the large area wall in the floor plan of the building. It can be applied to the assembly of small-area molds such as corridor walls or partition walls of pipe shafts, and since it is not cut, it reduces the cost burden and improves the efficiency of mold assembly. It can greatly improve the economic efficacy over metal foam panels.
