TECHNICAL FIELD OF THE INVENTION

The present invention relates to a structural joining system that provides moment resistance and does not use welding for the following applications. The applications are all areas of architectural design, engineering, fabrication, and field construction of reticulated structures using round tubular members.

[0002]

BACKGROUND OF THE INVENTION

Reticulated structures are generally made up of a network of two basic structural elements, the junctions and the interconnecting linear elements. When the linear element is a cylindrical tube, the joint with the joint is usually a pin joint due to the form of the joint mechanism.

Systems using pin-joint interconnect networks have been widely adopted in architectural design, engineering, fabrication, and field construction of numerous reticulated structures, including: The reticulated structures include, but are not limited to, domes, building facades, towers, stadium covers, bridges, and various truss applications.

Generally, a typical pin joint system employs a generally spherical joint point joined to multiple tubular frame members. The joint has an opening for receiving a part, such as a bolt, joint assembly, and the end of the tubular frame material is welded to another piece such as an end cone in the joint assembly. The ends of the tubular frame material may be tapered for the purpose of simplifying or strengthening the joint.

By joining each ball joint to a number of tubular frame members using a joint assembly, a network of joint points and frame members can be expanded and interconnected, resulting in a reticulated structure. Can be formed. Many variations of this common "tube and ball joint system" employ joints mounted in a flat surface joint assembly that is made by direct welding of the tubular frame material.

[0006] One type of tube and ball joint system uses a ball joint with multiple round openings for inserting and securing bolts or pins therein. A funnel-shaped sleeve having a hollow cylindrical base is located between the ball joint and the hollow cylindrical frame material.

The ends of the frame material are appropriately tapered to match the funnel shape of the sleeve tip. The tapered end of the frame material and the sleeve tip are welded to each other, and bolts are inserted through the frame material and further through the sleeve base, and are fixed by screwing at the joint point. Mounted on.

An externally attachable collar that can be secured to the bolt while being rotated is provided for tightening the bolt. In this way, the frame members are individually attached to the ball joints to form a mesh structure. In these configurations, shear,
Tensile and compressive stress can be applied by bolts. In some cases, the collar can carry compressive stress. In general, bolts work well for tensile stress, but
Shearing and compression are problematic.

Systems that use a pin-junction interconnect network can be employed in a reticulated structure in a variety of ways. The range of use of these is from those that mainly act as a load-bearing structure to those that give the appearance of the front of a building. For purposes as a network structure, it governs the determination of what compressive and tensile forces act on the system. The network is designed to withstand the calculated compressive forces and tension magnitudes and directions.

In order to effectively design such networks, it is necessary to develop a suitable model of the pin joint system employed in structural design. Desirably, the model should be as simple as possible without compromising engineering accuracy. Moreover, when a cylindrical frame material is adopted, the joining system used should optimize the compressive force load characteristics, which are common to the cylindrical tubes.

A typical tube and ball joint system has several deficiencies that become apparent when designing, engineering, fabricating, and field building braided structures. In a standard tube and ball joint system, the joint between each member-joint is typically modeled as a three part system: Part 3
The individual parts consist of a hinge at the joint, a short flexible material representing a bolt, and a tube.

The frame material is often tapered and welded to the funnel sleeve, which is then joined to the joint, so that there is a moment at the joint between the members and the joint, so that there is a three part The model is required to measure it with sufficient accuracy. The three-part model achieves the required accuracy because it incorporates short flexures and hinges. The three-part model is problematic because it introduces complexity into the design of reticulated structures.

In order to use a simpler model, a short flexible material representative of the bolt and / or a hinged collar can be omitted, between the frame material and the joint, at the joint. A structure having moment resistance will be required.

Tube and ball joint systems, however, are not able to withstand moments well at the joint. This is because current designs require the frame material to taper to the sleeve, requiring a collar and bolts. Reducing the frame material cross-sectional area at the junction is modeled as a hinge by design,
It will introduce additional structural elements, which typically impede the moment transfer at the junction.

As described above, in the connection by the pin under the load, a slight rotation occurs. Similarly, a short flexible material would not allow moment transfer. This prevents the frame material from being unloaded and therefore loudspeakers, lightweight assemblies, and other equipment must be installed at the joints. Not only that, when using a cylindrical material, the reduction of the cross-sectional area at the junction damps the compressive force loading characteristics.

To be practically employed in structural design, the joining system should be relatively easy to fabricate. In tube and ball joint systems, ball joints are difficult to fabricate and are often limited in size. Tube and ball joint systems also limit the material types that can be used.

Even though polymers, plastics, aluminum, various composites, and the like have the requisite strength, cost, and appearance design properties desirable for reticulation, such materials are often required for welding. Be careful. The use of welding to fabricate reticulated structures is costly and time consuming. Welding requires quality control standards, the use of raw materials and skilled craftsmen. In pipe and ball joint systems, the use of welding reduces the permissible load of certain materials and is therefore out of consideration for certain applications.

Finally, due to the complex nature of many of the reticulated structures, field construction and assembly is difficult and costly. Building these structures is a harsh and ruthless process, often in the process of building reticulated structures to both joints, which have not yet been joined to the frame material, already joined and fixed. The pre-assembled joint series, such as the frame material in Figure 3, has fixed the mating structure to be joined firmly in place, and it is not necessary to move the joint to join the pipe. Needs great power. This task is time consuming and can damage the structure.

In this way, a joint that can be simply modeled as an elongated member that can be fixedly attached to the joint without incorporating a hinge that defines the transfer of force at the joint and / or a short flexible material. It is desired to have a system. It is also desirable to develop a joining system in which the cylindrical member used does not have to noticeably reduce its cross-sectional area at the joining point.

Furthermore, there is no need for welding to attach the frame material to the joint, and yet a built-in gap is provided between the joints to give the function of inserting the frame material between the two fixing points. It would be desirable to have such a joining system.

The system components are easier to make, have a wider selection range for various material types,
It is also desirable to have a bonding system design method that has less shape constraints.

Furthermore, it is also desirable to avoid load bolts under shear and compressive stress.

[Outline of the Invention]

Therefore, as an example of the present invention, a coaxial junction (CAJ) system, and a CA
The assembly method of the J system is provided here.

The CAJ system provided herein, the moment resistant joint, comprises a frame material, a block connector, a compression sleeve, end caps attachable to the frame material and compression sleeve, and end cap-block connector attachment means.

The CAJ system, a preferred embodiment of moment resistant joints, is a cylindrical frame material, compression sleeves and complementary sawtooth screws for attaching the end caps to the frame material, as well as securing the end caps to the block connector. For this purpose, a tensile force bolt is used. The block connector and pull bolts may, in one embodiment, be hollow to support electrical wires or the like.

All or part of the reticulated structure can be constructed using the CAJ system, moment resistant joints. Such a structure consists of a number of frame materials, block connectors, compression sleeves, end caps, and end cap-block connector attachment means.

To assemble the CAJ system, a compression sleeve is slid into the frame material and placed near the end of the member. The frame material is then placed near the block connector. Place the end cap, which is movably attached to the block connector, and the frame material in a linear alignment. Once in linear alignment, move the end cap toward the end of the frame material and install. The sleeve is then slid over the end cap towards the block connector and attached to the end cap.

Embodiments of the present invention are described with reference to the following drawings, which are modified standard engineering drawings. The information contained in the figures is incorporated as a detailed description of the invention. However, various changes can be made to the contents shown in the drawings without departing from the scope of the present invention.

[0029]

[Detailed description]

The dome-shaped mesh structure 9 on the foundation as shown in FIG. 1 is C as shown in FIGS.
At least one AJ system 11 is used. In one embodiment of the system, a plurality of CAJ system connectors are used, each connector 12 comprising a three-way block connector 14, a frame member 15, and a frame member-connector mounting unit 16. In effect, through the frame material-connector attachment unit 16, the frame material 15 is attached to the block connector 14 and functions as a junction element.

In FIG. 4, a mounting unit 16 used in the CAJ system includes a compression sleeve 18 in which a frame material 15 is inserted, an end cap 19 capable of joining the frame material 15 and the sleeve 18, and a cap 19 to a connector 14. And an attachment mechanism 20 for fixing to. The end cap and the sleeve each comprise an inner and outer portion, the attachment mechanism acting as a pull force carrier and the sleeve acting as a compressive force carrier. The end cap can freely slide on the attachment mechanism, and the frame member, the end cap, the sleeve, and the attachment mechanism are aligned with each other.

This embodiment has a frame material connector with an outer diameter (OD) or an external thread. The end cap 19 is in the shape of a cylindrical cup, the opening 22 in the bottom of which receives a mounting means 20, for example a pull bolt. The end cap 19 has a hollow portion 23 which can be reached from the upper opening. The pull bolt is inserted through the hollow in the cap and the opening 22 and screwed into the block connector to a predetermined depth. Thus, the separation of the end cap from the connector is limited. A saw tooth screw 34 is engraved on the inner cap surface, and a saw tooth screw 36 is engraved on the outer cap surface. Both screws extend perpendicular to the mating surface of the connector.

The end cap can be bonded to the connector in the field or at the factory. However, since it is not necessary to use bolts at the construction site, it is desirable to join them at the factory, which saves time at the construction site. Also, by setting the bolts to a predetermined depth in the connector, the dimensional control of the structure can be simplified. The base 24 of the end cap is parallel to the connector and can be tangential to the mating surface 28 on the connector. Alternatively, it can move along the bolt and contact the washer 30 between the bolt head 32 and the base of the end cap. Thus, there is a limit to the extent to which the end cap can be separated from the junction element. The mating surface 28 has a circular recess into the connector. The recess has a diameter that exactly receives the outer diameter of the sleeve. Thus, the joining of the connector recess and the sleeve creates a shearing force.

The cylindrical frame member 15 having the distal and distal ends with respect to the connector can be attached to the hollow surface of the end cap. A sawtooth screw 40 is engraved on the outer surface of at least one end of the frame material to complement the sawtooth screw 34 on the end cap. Thus, the bolt, the end cap and the frame material create a tensile force. This pulling path goes from the connector to the bolt, from the bolt through the washer to the end cap, and from the end cap through the screws 34, 40 to the frame material.
Serrated screws provide relatively little support in compression. In addition, the end cap can slide over the bolt toward the connector, so that no compressive force is applied to the bolt.

Therefore, a hollow cylindrical sleeve 18 is provided. The sleeve 18 has a diameter sufficient to enclose both the frame material and the end cap and functions as a length adjuster. That is, the functional length of the frame material is made larger than its actual length, and it is slidable with respect to the frame material. The hollow part of the sleeve 18 can be reached from the upper and lower openings. The sleeve 18 has a sawtooth screw 38 on its inner surface that is complementary to the sawtooth screw 36 on the outer surface of the end cap. The end cap serves to secure the sleeve between the frame material and the connector. The compressive force is taken up by the sleeve, the end cap and the frame material. The compression path is from the connector to the sleeve, from the sleeve to the end cap via a threaded joint, and from the end cap to the frame material via the mounting of the end 42 of the frame material on the circumferential shoulder 44 of the end cap. Go to. The shoulder thus constitutes a thrust seat for the application of compressive forces.

The serrated screw is reinforced to prevent the end cap from being pushed into the sleeve. The abutment joint between the sleeve and the connector does not provide support for pulling forces. However, the joint unit as a whole provides a perfect joint that withstands these forces because its elements withstand tensile, compressive and shear forces well. Also, since the frame material is attached to the connector by the joining unit having no reduced diameter, a moment resistant joint is formed.

5 to 8, when assembling the frame material of the CAJ type system,
The bolt 20 with the washer 30 attached is threaded through the base 24 of the end cap 19 into the connector 14 attached to the end cap. The frame material 15 is then inserted through the sleeve and the screws on the outer surface of its ends are positioned to align with the end caps between the two connectors. This makes the frame material, sleeve, end cap and bolt coaxial. Due to the length of the frame material, a gap 46 remains at each end between the frame material and the bolt so that the frame material can be easily inserted between the two connectors.

Only one end of the frame member will be described for assembly. A portion of the washer and bolt is in the hollow of the end cap and the end cap is moved toward the frame material as indicated by arrow 48 in FIG. A sawtooth screw on the inside surface of the end cap is screwed into a sawtooth screw on the outside surface of the frame material and is tightened until the end portion 42 of the frame material is in firm contact with the shoulder portion 44 of the end cap. Here, the washer 30 is tightly engaged between the bolt head 32 and the base surface of the end cap 19 (which constitutes the bottom surface of the hollow portion 23).

In the system shown in FIGS. 2-8 and 9, the shaft portion near the head of each bolt 20 is not threaded and is preferably non-circular, eg hexagonal,
Allow the engagement rotation with a spanner. Thus, the bolt is first positioned with its head well away from the connector so that the end cap moves along the bolt and its shoulder 42 makes the desired abutment with the end of the frame material 15. The gap or looseness between the bolt head and the washer 30 and the base of the end cap recess should be ensured that the bolt is screwed into the end cap and the washer 30 is snug between the bolt head and the end cap. And prestressing the bolts if necessary and removed.

The sleeve 18 is then moved along the frame towards the end cap, the sawtooth screw on the inner surface of the sleeve is screwed into the sawtooth screw on the outer surface of the end cap, and when further tightened, the lower end of the sleeve 18 joins the connector. It abuts the surface 28 exactly. Once the joint is assembled, the joint is secured with screws 21 that abut the threads on the end caps.

The length of the frame material is determined by the design restrictions of the structure. However, once the length is chosen, the tolerances should be low to ensure conformance with the end cap and to align the sleeve distal end 50 with the end cap.

The end surface cap is screwed onto the frame material using a spanner to join the joint surface 2 of the connector.
Abut on 8. For this spanner, the handle is lengthened to bend the head, and the projecting portion projects from the head toward the handle. Depending on the embodiment, the sleeve, end cap and frame material have openings 45 (FIG. 2) which receive the spanner.

In a properly assembled connector 12, the tight engagement between the end cap shoulder 44 and the frame material end 42 is ensured by the washer 30 between the bolt head 32 and the end cap 19. Retained. This causes the sleeve to abut the mating surface 28 and is sufficient to keep the elements in contact with each other within the thermal expansion and contraction experienced by the elements. Although the connector 14 is shown to have a hexagonal shape, it is not limited to this in practice. It is also a three-dimensional structure for use in various spatial frames. The connector must be sufficient to accommodate the multiple frame materials that need to be installed.

The size, shape and structure of the connector may be any as long as this point is taken into consideration. Without the physical demands of spherical joints, CAJ systems are more suited to spatial frame applications and can be assembled more efficiently. Similarly, frame material 15
Is preferably linear and cylindrical in shape, but the frame material is not rotated when actually implementing the CAJ system. Therefore, the frame material is not limited to the shape as described above. The frame material may be of any size and shape, such as a curved tube, a twisted tube, a prismatic cross-section tube, an octagonal cross-section tube, etc. In short, the end of the frame material may be attached to the end cap. Such a unique frame material-connector mounting unit attaches the frame material to the connector without manipulation or rotation of the frame material, thus allowing the use of non-cylindrical, non-linear or even entangled frame material.

The CAJ system has various advantages because it consists of elements joined at a rigid joint. The absence of tilted junctions allows the transfer of moments and simplifies the design without the need to use hypothetical hinges to form the expected mesh structure. Due to its moment resistance capability, the CAJ system can also be used in malleable frames and triangular frames. Furthermore, the frame material can be treated like a beam.
The load is placed on the frame material, so equipment such as loudspeakers and lights can be installed at the most convenient location, whether at the junction or the frame material.

Since the CAJ system uses the frame material that is fixed to the connector in a moment-resistant fixed manner, the advantage of the compression resistance of the frame material can be utilized to a greater extent, and its durability is the standard pipe and ball joint point. Up to twice the system. As a result, the CAJ system can be loaded with the same load bearing capability as a similarly sized tube and ball joint system, even with halved diameter and doubled length tubes.

By eliminating the need to weld frame material to the joining unit, the CAJ system increases the width of materials that can be used in the field of structural construction. It is possible to use various materials having desired strength, cost, aesthetics and the like, which are weak against welding, without fear of damage due to welding, and to reduce applied stress.

The elimination of welding also allows for faster assembly, lower costs, fewer steps, less material consumption, and greater flexibility in building structures.
In particular, because the CAJ system provides a built-in clearance for the frame material, inserting the frame material between the two connectors is no longer a problem. Unlike some tube and ball joint systems, the CAJ system facilitates loading and exchanging frame material between two fixed joints. This is possible because the sleeve fills some of the length between the connectors and the sleeve overlaps the frame material before joining.

Any rigid material can be used for the CAJ system. In particular, since welding is not required at the time of assembly, a material that is weak against welding, such as aluminum or a composite material, can be used without impairing properties such as strength and ductility.

FIG. 9 shows the second embodiment of the CAJ system including the internally threaded frame member. Here, the same elements as those described above are indicated by adding a subscript A.
The end cap 19A is attached to the block connector 14A via a threaded stud 80, two jam nuts 82 and a washer 30A. With this structure, the maximum separation distance of the end cap from the connector can be adjusted in the field, and the frame material can be in a desired fixed state between the two connectors.

The end cap is cylindrical and has a hollow portion that can be reached from the upper opening, and it is desirable that the end cap has a constant diameter throughout the hollow portion. The outer shape of the end cap varies, and the head 52 has a smaller outer circumference than the bottom 54. The head is provided with a sawtooth screw 34A on the outside, and the inner sawtooth screw 40A of the frame material 15A is engraved.
Screw together. A sawtooth screw 36A is engraved on the outer side of the bottom portion of the sleeve 18A.
It is screwed with the upper inner serrated screw 38A.

The frame material can be attached to the outer screw of the head portion 52 of the end cap, and has a serrated screw 40A on the inner surface of the end portion. The base of the end cap is the connector joint surface 28
It extends parallel to A and can contact the surface. The stud extends through the base of the end cap and into the connector. The jam nut 82 and the end cap base 24A are separated by the washer 30A, and the stud is screwed into the connector.

The sleeve 18A has a diameter sufficient to surround the frame material 15A and the end cap 19A, functions as a length adjusting body, and is slidable with respect to the frame material. The hollow portion of the sleeve can be reached from both the upper opening and the bottom of the sleeve. A saw tooth screw 38A complementary to the saw tooth screw 36A on the outer periphery of the bottom of the end cap is engraved on the surface of the hollow portion. The end cap serves to secure the sleeve between the frame material and the connector. That is, it resists moments applied to or from the frame material between the end cap and the connector 14A.

This frame material is assembled as in the previous embodiment. That is, the pulling rod with washer and lock nut is passed through the bottom of the end cap and screwed into the connector to movably attach the end cap to the connector. The frame material is then inserted through the sleeve and the frame material is positioned such that its screws are in line with the end caps. The end cap along with the washer and a portion of the pull stud are moved towards the frame material.

The sawtooth screw on the outer circumference of the end cap is screwed with the sawtooth screw on the inner surface of the frame member, and is tightened using a spanner or the like. When the washer 30A fits snugly between the end cap base and the jam nut, the lower end 44A of the frame material is flush with the shoulder 42A of the end cap. The sawtooth screw on the inner surface of the sleeve is screwed into the sawtooth screw on the outer surface of the end cap, and when tightened with a spanner, the lower end of the sleeve is connected to the connector joint surface 2
It is exactly 8A.

The sawtooth screws for attaching the complementary frame materials to the end caps and the sawtooth screws for attaching the sleeve to the end caps can be reversed in screw direction to facilitate assembly. For example, by screwing the end caps into the frame material by interchanging the screw directions, the sleeve can be attached to the end caps without reversing the original threaded connection between the end caps and the frame material. Can be screwed. The screw direction may be clockwise or counterclockwise, provided that the end caps to the frame material and the end caps to the sleeve can be misplaced between the two attachment points. Although complementary sawtooth screws were used in this embodiment as the means for attaching the frame material to the end caps and the sleeve to the end caps, other attachment means such as welding, if not preferred, are used in the CAJ system. May be.

In another embodiment, the tension bolt 60 is axially hollow, and the wire W passes through the central passage 64 of the bolt through its opening 62, as shown in FIG. As described above, the shape of the connector is not limited to that shown in the figure. In short, it suffices if the mounting unit 16 can position the frame member 5 fixedly with respect to the connector 14.

In the embodiment shown in FIGS. 11 and 11A, the connector 70 is hollow and each joint surface 7
4 has an opening 72 to receive the wire used in the mesh structure. The connector is also formed with a hatch 78 that allows for the passage of wires.

Although the frame material has been described as having an internal hollow, it does not have to be solid and substantially hollow. The solidity of the frame material depends on the required load capacity and other design factors.

Although the CAJ system in the above examples uses tension bolts to attach the end caps to the connector, other attachment means such as full threaded studs may be used.

In addition, the CAJ system can also be equipped with a threaded bush to join pipes of different diameters as shown in FIG. The bush 79 allows tubular frame members 80 of different sizes to be joined to the same connector.

Further, the flexibility of the design of the connector 14A, the spot surface recess 28A, the sleeve 18A, and the end cap 24A allows the system to receive tubular frame materials of various diameters at the same juncture. No threaded bush 79 is required.
