Description

Technical Field

[0001] This utility model relates to the field of load-bearing truss technology, and in particular to a prefabricated deployable truss used in the fields of architecture, mechanical engineering and aerospace. Background Technology

[0002] In fields such as construction engineering, bridge engineering, mechanical engineering, and aerospace, truss structures are widely used because they can withstand axial forces, fully utilize material strength, and have advantages such as light weight and high load-bearing capacity.

[0003] However, existing truss structures have the following shortcomings in temporary load-bearing applications:

[0004] 1. High complexity in manufacturing and installation: Traditional trusses are composed of a large number of components and nodes, which are often connected by welding. This requires high precision in processing, accurate assembly, and skilled operators, resulting in increased manufacturing costs and extended construction periods.

[0005] 2. Inconvenient transportation and large storage space requirements: The rigidity and non-foldable nature of traditional trusses cause them to occupy a large amount of space when not in use, increasing storage costs and management difficulties. At the same time, it restricts transportation methods, usually requiring segmented transportation and on-site assembly, which further increases the difficulty and cost of transportation and installation.

[0006] 3. Insufficient out-of-plane stiffness and significant stability issues: As a planar structure, trusses have relatively low out-of-plane stiffness, resulting in significant out-of-plane stability problems. While welding three-dimensional trusses to enhance stability can enhance stability, this method involves high precision requirements and is difficult to implement.

[0007] Therefore, those skilled in the art are dedicated to developing a foldable and highly rigid prefabricated deployable truss. Summary of the Invention

[0033] Example 1, such as Figures 1 to 7 As shown, a prefabricated deployable truss includes a foldable truss 100, a first X-shaped diagonal brace 200, a second X-shaped diagonal brace 300, and a transverse support link 400. Two symmetrical foldable trusses 100 are provided. The first X-shaped diagonal brace 200 connects the upper ends of the two foldable trusses 100. The upper end of the second X-shaped diagonal brace 300 is connected to the upper end of the foldable truss 100, and the lower end of the second X-shaped diagonal brace 300 is connected to the lower end of the foldable truss 100. Both ends of the transverse support link 400 are connected to the foldable trusses 100 located on the same side. From a stress perspective, this three-dimensional structure, through the first X-shaped diagonal brace 200, the second X-shaped diagonal brace 300, and the transverse support link 400, ensures that the deployable structure possesses sufficient lateral stiffness, torsional stiffness, and overall structural integrity when deployed.

[0034] The foldable truss 100 includes an X-shaped folding frame 101, an upper chord 102, a lower chord 103, and a longitudinal support rod 104. The lower chord 103 is a steel wire rope, and its lower end is connected to the two legs of the X-shaped folding frame 101 at its lower end. The upper end of the X-shaped folding frame 101 is hinged to the upper chord 102, and its lower end is connected to the lower chord 103. The two ends of the longitudinal support rod 104 are detachably connected to the upper chord 102 and the lower chord 103, respectively. Since the X-shaped folding frame 101 is composed of two folding strips that are hinged together in the middle, it can be folded up and down and unfolded, has a high shrinkage rate, greatly facilitates the storage and transportation process, effectively reduces the required storage space, and significantly reduces transportation costs and difficulties.

[0035] Furthermore, the foldable truss 100 also includes a first upper chord mid-section connector 105 and a second upper chord mid-section connector 106. The first upper chord mid-section connector 105 includes an integrated first upper chord end sleeve 107 and a diagonal brace sleeve 108 connected end to end. The diagonal brace sleeve 108 is sleeved on one leg of the X-shaped folding frame 101, and the first upper chord end sleeve 107 is sleeved on the upper chord 102.

[0036] The foldable truss 100 further includes a first upper chord end connector 114 and a longitudinal support rod connector 115. The first upper chord end connector 114 includes an X-shaped folding frame sleeve 116, one leg of which is inserted into the X-shaped folding frame sleeve 116. The longitudinal support rod connector 115 includes a longitudinal support rod sleeve 117, which is sleeved on the longitudinal support rod 104.

[0037] The first X-shaped diagonal brace 200 includes a first X-shaped connector 201, a first diagonal brace tube 202, and a first diagonal brace tube connector 203. The first X-shaped connector 201 has four connecting feet. One end of the first diagonal brace tube connector 203 is sleeved on the end of the first diagonal brace tube 202, and the other end has a first connecting lug 204 for connecting the connecting feet. The connecting feet have diagonal brace connecting holes, and the first connecting lug 204 has a first through hole 205 coaxial with the diagonal brace connecting hole. The first through hole 205 is provided with a bolt assembly. The second X-shaped diagonal brace 300 has the same structure as the first X-shaped diagonal brace 200, only the installation location is different, so those skilled in the art will understand this, and therefore it will not be described in detail here.

[0038] The bottom surface of the diagonal brace sleeve 108 is integrally provided with an outwardly extending first upper chord connecting plate 109. The middle connector 106 of the second upper chord includes a second upper chord end sleeve 110 with a closed rear end. The bottom of the second upper chord end sleeve 110 is provided with an outwardly extending second upper chord connecting plate 111. The first upper chord connecting plate 109 and the second upper chord connecting plate 111 are respectively provided with coaxial upper chord connecting through holes 112. The upper chord connecting through holes 112 are provided with pins.

[0039] The first upper chord end sleeve 107 and the diagonal brace sleeve 108 are respectively provided with transversely penetrating upper chord fixing holes 113. A pin is provided in the upper chord fixing hole 113. When the pin is pulled out, the first upper chord end sleeve 107 and the diagonal brace sleeve 108 can rotate freely. In this way, the longitudinal resistance of this prefabricated deployable truss is eliminated, and the X-shaped folding frame 101 can be folded and retracted longitudinally.

[0040] The X-shaped folding frame sleeve 116 has a first longitudinal support rod connecting plate 118 extending outward on one side of its top end, and a second longitudinal support rod connecting plate 119 extending outward on the other side of its bottom end. The longitudinal support rod connector 115 has a third longitudinal support rod connecting plate 120 extending outward. The first and second longitudinal support rod connecting plates 118 and 119 each have a strip-shaped hole 121, and the third longitudinal support rod connecting plate 120 has a longitudinal support rod adjusting hole 122 facing the strip-shaped hole 121. The upper end of the longitudinal support rod 104 is hinged to the lower end of the longitudinal support rod sleeve 117.

[0041] The preferred embodiment of this design comprises an X-shaped folding frame 101, upper chords 102, steel wire ropes 103, and longitudinal support rods 104. Multiple upper chords 102 are connected end-to-end via a first upper chord mid-section connector 105 and a second upper chord mid-section connector 106. Multiple steel wire ropes 103 are also connected end-to-end. The longitudinal support rods 104, longitudinal support rod connectors 115, and the end connectors 114 of the first upper chord are interconnected, forming a lateral resistance for the entire deployable truss, ensuring structural strength. Furthermore, it significantly enhances lateral stiffness and overall stability, enabling it to adapt to complex and changing environments, meet diverse usage requirements, and exhibit excellent resistance to lateral loads.

[0042] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
