Description

[Detailed description of the invention] Background of the invention field of invention The present invention relates to a space frame.

Description of prior art The space frame is specifically designed to maximize floor space with a minimum of supports. Widely used when it is safe to erect a cover over a large area to ensure It is used. Space frames are usually vertically spaced vertically spaced apart from each other. It is a two-layer type consisting of an upper grid and a lower grid made of chords and horizontal chords. The knots or intersections of the chords of the side grid and the knots of the chords of the lower grid are diagonally supported. They are interconnected by timbers or braces.

The two grids are offset from each other both vertically and horizontally with respect to their nodes. each nodule on one grid, except for the nodules on the periphery of the upper grid. At the same distance from the four nodes of the other grid, insert the reeds and diagonal supports. It is connected to four nodes. Therefore, at each node, the intersecting chords and Provision shall be made for interconnecting a series of diagonal struts.

The strings and struts are generally preferably a single cylindrical member, with one tube inserted at each node. It is desirable that the axes of the longitudinal and transverse chords intersect the axes of the struts. but However, the space that satisfies these comfortable living conditions is generally low manufacturing cost. They have connectors, strings and struts that are expensive and laborious to install. Ru.

Summary of the invention The present invention allows strings and struts to be manufactured simply and economically, quickly and responsibly. Space frames of the above type can be easily connected to each other in an optimal relationship. It was developed for the purpose of providing.

In order to achieve the above and other objects, the present invention provides longitudinal and transverse chords, respectively. It has an upper grid and a lower grid consisting of a nodule of the upper grid and a lower grid. This is a type of space frame in which the joints of the upright connectors at the ends of the segments of the longitudinal and transverse chords at each node; The plates are arranged as a medium-shaped assembly, with the ends of the diagonal struts at right angles to each other. An articulated flange engages each of the cylindrical assemblies and connects the flanges and their The connector plates of the middle letter assembly sandwiched in between are connected by fasteners. We provide space frames featuring:

Preferably, the longitudinal chord members and the transverse chord members are cylindrical, and the connector plate is arranged in each longitudinal chord. It shall consist of a flattened section at the end of the cross member and cross chord member. Also, before Preferably, the diagonal struts are also cylindrical, and both ends of each strut are connected to the cylindrical body of the strut. forming flanges at right angles to each other joining along lines oblique to the axis of the parts; It is assumed that it has been flattened and bent so that Other features of the invention include: It will become clear from the description.

FIG. 3 is a plan view of the intersection shown in FIG. 2.

FIG. 4 is a view from below of the above-mentioned intersection.

FIG. 5 is a perspective view of one end portion of the diagonal strut of the space frame.

Figure 6 is taken along the line 6-6 in Figure 1. It is larger than Figure 1, but compared to Figures 2 to 4. is a cross-sectional view to a small scale of the space frame (roof) of the invention illustrated here. The frame consists of an upper grid (lattice body) consisting of vertical chord members 10 and horizontal chord members 11; 12 and the lower grid consisting of the horizontal chords 13, and the node of the upper grid, that is, the intersection of the chords. and a diagonal strut 14 interconnecting the nodes or intersections of the lower grid. ing. This space frame includes an upright space frame support 16. It is supported horizontally inside the outer wall 15. Space frame support 16 is What is the role of lion (vertical window partition)? Also accomplish. This space frame is a floor spring A ceiling panel 18 is installed below the frame.

At the nodes of the upper grid of the space frame shown in Figures 2-4, One vertical chord member 1o, two segments of the horizontal chord member 11, and four diagonal struts 14 are mutually connected. is rigidly connected to. All of these members have a round cross section and the same diameter. It is a metal tube.

The longitudinal chord member 10 forms an upright (vertically flat) connector plate 19 at the node. The nodal ends of the transverse chord members 11 are also flat on both sides of the center of the connector member 19. It is flattened to form an upright connector plate 20 that intersects in a cross shape at right angles to the plane. ing.

All of the four diagonal supports 14 are of the same type, and both ends of each are metal pressed. It is deformed and flattened by the engineering process, and the flattened part is formed into the shape of a chevron-shaped member. The two flanges 21 are connected at right angles, and the connecting line, that is, the ridgeline, It extends obliquely to the axis of the main cylinder. Two bolts on each flange 21 A hole 23 is formed.

Each of the upright connector plates 19 of the longitudinal chords 10 and the upright connector plates 20 of the transverse chords 11 Bolt holes (not shown) are also drilled in the holes. These bolt holes are The deformed and bent ends of the upright connector plates of the vertical and horizontal chords are connected to the center-shaped assembly. When positioned as shown in one corner, bolt 25 is inserted into the strut. The alignment of the flanges 21 and the connector plates 19 and 20 of each chord sandwiched between them The whole assembly can be fixed by passing it through the bolt hole and tightening the nut 25'tl. It is arranged like this. Each member (chords and struts) is shown in dashed lines in Figure 2. The copper wires of each string and strut are formed and arranged so that they intersect at one point. Ru.

Instead of forming the transverse chords 11 as segments flattened at both ends, each transverse chord can be flattened at each node in the same way as the longitudinal chords. In that case, the longitudinal chord A slot is formed from above in the flat part of one of the horizontal chord members. , a slot is formed from below in the flat part of the other string, and both strings are connected at each node. and then fit them together so that their axes lie in a common plane.

As a further alternative, the longitudinal and horizontal chords can be taught as segments with the same number, and each segment's Both ends are flattened, bolt holes are formed in the flattened parts, and longitudinal chords are inserted at each joint. The two segments and the two segments of the transverse chord are connected as a cross-shaped assembly and supported. The material 14 is sandwiched between each pair of fins 21 and fixed with bolts.

In the space shown in the frame A, both sides and both edges of the upper grid are at the bottom. Extend beyond the side grids and attach each peripheral knot except for the knots at each corner of the upper grid. At the joint, only the two diagonal struts are connected. In these peripheral nodules , a simple batten is bolted to the outside of the knot. Also, each of the upper grid At the corner knot, only one diagonal strut is connected, and there is a simple connection on the outside of the knot. A simple angle bracket (not shown) is bolted on.

All struts of the Conospace frame can be the same, and each grid All longitudinal chords of the frame and all segments of the transverse chords of the frame are the same. This space can be structured so that each part used in the construction of the frame The material can be easily and economically manufactured and can be produced quickly without requiring high levels of skill. Can be bolted to. Both horizontal and vertical chord members were constructed as segmented bodies. In some cases, the entire space frame can be constructed using just two basic structural members, i.e. It can be constructed with only members and similar struts.

The floor panel 17 is a column-shaped reinforced concrete structure that is square in plan view. Each layer is thickest in the center and decreases in thickness toward the west side. On the west side, there is a reverse cross-section welded or otherwise secured to the upper grid. It is supported on a grid of letter-shaped floor panel supports 26. ceiling panel The holes 18 may be made of fire-resistant soundproofing material, for example, and are also square and have four sides. and fixed by any suitable means to the underside of the lower grid of the space frame. It is supported by a grid of T-shaped bars 27.

If this space frame is needed to support the roof or ceiling In this case, each node of the space frame is covered with a tubercle cap 28 (Fig. 2). You can The cap shown is cylindrical with a closed top and has a string and A slot 29 from below is formed which is shaped to fit into the knotted end of the strut. There is. A similar cap can be inverted and placed over the nodules of the lower grid. , both the upper grid cap and the lower grid cap are secured by any suitable method. determined.
