Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, specifically to a truss that can be quickly assembled and erected. Background Technology
[0002] The concept of truss bridges can be traced back to the 19th century, when the Industrial Revolution brought about advancements in steel production, making it possible to construct large truss structures. The earliest truss bridges mostly used wood, but due to the limited strength and durability of wood, it was quickly replaced by steel. In the early stages of bridge construction, newly poured concrete formwork needed to be supported until the concrete reached sufficient strength to stand on its own.
[0003] In the field of bridge construction technology, trusses can be used to support formwork systems in the early stages of bridge construction so that concrete structures can be poured. Trusses can also serve as part of a temporary support structure to support newly poured concrete until it reaches sufficient strength. Furthermore, trusses can be used to construct construction platforms, providing a safe working environment for construction workers and facilitating their work at heights.
[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When installing the equipment, workers need to use tools and a large number of screws to assemble it, and the assembly steps are too cumbersome and require a lot of time; 2. When transporting the equipment, the equipment is fixed and cannot be folded, which will occupy a lot of space, resulting in low space utilization and affecting the loading and transportation of the equipment. Utility Model Content
[0005] The purpose of this invention is to provide a truss that can be quickly assembled and erected, so as to solve the problems of inconvenience in assembly and inability to fold mentioned in the background art. To achieve the above objectives, this utility model provides the following technical solution: a truss that can be quickly assembled and erected, comprising a right main body, a main rotating block installed on one side of the right main body, a main rotating shaft attached to one side of the main rotating block, a rotating frame installed on one side of the main rotating shaft, a main sliding block provided on the other side of the right main body, a main insert block connected to one side of the main sliding block, an insertion hole provided on one side of the main insert block, a left main body provided on one side of the rotating frame, a main slot provided at the bottom of the left main body, a secondary slot provided at one end of the main rotating block, a secondary rotating block attached to one side of the left main body, a secondary rotating shaft attached to one side of the secondary rotating block, a support frame installed on one side of the secondary rotating shaft, a secondary sliding block provided on one side of the support frame, a secondary insert block connected to one side of the secondary sliding block, a fixed outer shell installed at one end of the secondary rotating block, a tie rod attached to the inner wall of the fixed outer shell, and a telescopic spring attached to one side of the tie rod.
[0006] More preferably, the rotating frame is X-shaped.
[0007] More preferably, the rotating frame forms a rotating structure through the cooperation of the main rotating block and the main rotating shaft.
[0008] More preferably, the main insertion block forms a telescopic structure through the main sliding block.
[0009] More preferably, the support frame forms a rotating structure through the cooperation of the secondary rotating block and the secondary rotating shaft.
[0010] More preferably, the secondary insertion block forms a telescopic structure through a secondary sliding block.
[0011] More preferably, the pull rod forms an elastic structure through the cooperation of the fixed housing and the telescopic spring.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In this invention, a main insert block and a fixed outer shell are added. During the assembly of the equipment, the trusses are parallelly connected, and then the main insert block is extended and retracted by sliding the main sliding block, so that the main insert block is inserted into the main slot to connect the trusses. Then, by pulling the tie rod, the telescopic spring drives the tie rod to extend and retract, so that the tie rod is inserted into the insertion hole on the main insert block to limit the main insert block, so that the trusses can be quickly spliced and the installation period of the trusses can be shortened.
[0014] In this invention, a main rotating shaft and a support frame are added. When the truss is disassembled and transported, the sliding block of the sliding pair is used to pull the auxiliary insert block out of the auxiliary slot. Then, the auxiliary rotating shaft is rotated to drive the support frame to rotate and fold the support frame. Then, the main rotating shaft is rotated to drive the rotating frame to rotate and fold laterally, so that the truss is folded as a whole, thereby reducing the space occupied by the truss and facilitating the storage and transportation of the truss.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a truss that can be quickly assembled and erected, including a right main body 1, a main rotating block 2 installed on one side of the right main body 1, a main rotating shaft 3 attached to one side of the main rotating block 2, a rotating frame 4 installed on one side of the main rotating shaft 3, a main sliding block 5 provided on the other side of the right main body 1, a main insert block 6 connected to one side of the main sliding block 5, an insertion hole 7 provided on one side of the main insert block 6, a left main body 8 provided on one side of the rotating frame 4, a main slot 9 provided at the bottom of the left main body 8, a secondary slot 10 provided at one end of the main rotating block 2, a secondary rotating block 11 attached to one side of the left main body 8, a secondary rotating shaft 12 attached to one side of the secondary rotating block 11, a support frame 13 installed on one side of the secondary rotating shaft 12, a secondary sliding block 14 provided on one side of the support frame 13, a secondary insert block 15 connected to one side of the secondary sliding block 14, a fixed outer shell 16 installed at one end of the secondary rotating block 11, a tie rod 17 attached to the inner wall of the fixed outer shell 16, and a telescopic spring 18 attached to one side of the tie rod 17.
[0022] In this embodiment, as Figure 1 As shown, the rotating frame 4 is X-shaped. By making the rotating frame 4 X-shaped, when the bridge module is temporarily supported by the truss, the X-shaped support can effectively increase the lateral stiffness of the structure and prevent the structure from lateral displacement under the action of lateral wind force. Since the X-shaped rotating frame 4 forms diagonal support, this structure can significantly reduce the overall deformation of the structure.
[0023] In this embodiment, as Figure 1 As shown, the rotating frame 4 forms a rotating structure through the cooperation of the main rotating block 2 and the main rotating shaft 3; by installing the main rotating shaft 3 on one side of the rotating frame 4, the rotating frame 4 can rotate through the main rotating shaft 3, which can make the rotating frame 4 turn horizontally as a whole, thereby reducing the lateral volume of the truss and facilitating the installation and transportation of the truss.
[0024] In this embodiment, as Figure 1 and Figure 3 As shown, the main insertion block 6 forms a telescopic structure through the main sliding block 5; by installing the main insertion block 6 on one side of the main sliding block 5, and by sliding the main sliding block 5, the main insertion block 6 can extend and retract with the main sliding block 5, so that the main insertion block 6 can be inserted into the main slot 9, thereby connecting the trusses and increasing the installation speed of the trusses.
[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the support frame 13 forms a rotating structure through the cooperation of the secondary rotating block 11 and the secondary rotating shaft 12. By installing the secondary rotating shaft 12 on one side of the support frame 13, the support frame 13 is rotated by rotating the secondary rotating shaft 12 during the transportation of the truss, so that the support frame 13 is parallel to the right main body 1, which facilitates the disassembly and folding of the truss.
[0026] In this embodiment, as Figure 3 As shown, the auxiliary insert 15 forms a telescopic structure through the auxiliary sliding block 14; by installing the auxiliary insert 15 on one side of the auxiliary sliding block 14, the auxiliary insert 15 slides together with the auxiliary sliding block 14 by sliding the auxiliary sliding block 14, so that the auxiliary insert 15 can be inserted into the auxiliary slot 10, so that the support frame 13 provides lateral support to the truss, thereby increasing the installation strength of the truss.
[0027] In this embodiment, as Figure 4 As shown, the tie rod 17 forms an elastic structure through the cooperation of the fixed housing 16 and the telescopic spring 18; by installing the telescopic spring 18 on one side of the tie rod 17, the tie rod 17 is pulled to cause the telescopic spring 18 to drive the tie rod 17 to extend and retract, so that the tie rod 17 is inserted into the insertion hole 7 to limit the main insertion block 6, making the connection between the trusses more secure.
[0028] The method of use and advantages of this utility model: The truss that can be quickly assembled and erected operates as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the trusses are aligned parallel to each other. Then, by sliding the main sliding block 5, the main insert block 6 extends and retracts with the main sliding block 5, allowing the main insert block 6 to be inserted into the main slot 9. Then, by pulling the tie rod 17, the telescopic spring 18 drives the tie rod 17 to extend and retract, allowing the tie rod 17 to be inserted into the insertion hole 7 on the main insert block 6, thus connecting the main insert block 6 and the main slot 9 to complete the truss assembly. When the truss is used and disassembled for transportation, the tie rod 17 is pulled out from the insertion hole 7 for quick disassembly. Then, by sliding the secondary sliding block 14, the secondary insert block 15 is pulled out from the secondary slot 10. Then, the secondary rotating shaft 12 is rotated to drive the support frame 13 to rotate, thus folding the support frame 13. Then, the main rotating shaft 3 is rotated to drive the rotating frame 4 to rotate, thus rotating and folding the rotating frame 4 laterally, thereby reducing the space occupied by the truss and facilitating the storage and transportation of the truss.
