This operating platform has a simple structure, the connections between components are reliable and easy to disassemble and install, individual components are lightweight, the platform can be installed and disassembled without the assistance of mechanical equipment, it can be easily and quickly transported between various construction points, and has a high reusability rate.

[0004] During construction, ground personnel usually pass tools or parts to the construction workers on the construction platform. However, the height difference between the construction workers on the platform and the ground personnel makes it difficult for the ground personnel to pass the tools or parts to the construction workers on the platform. Summary of the Invention

[0005] The purpose of this invention is to provide a construction platform for the lower chord connection joint of a steel truss, which solves the problem that the height difference between the construction personnel on the platform and the personnel on the ground makes it difficult for the personnel on the ground to pass tools or parts to the construction personnel on the platform.

[0006] To achieve the above objectives, the present invention provides a construction platform for the lower chord connection joint of a steel truss girder, comprising a load-bearing frame and steel scaffolding, wherein the steel scaffolding is mounted on the load-bearing frame.

[0026] This invention provides a construction platform for the lower chord connection joint of a steel truss, comprising a load-bearing frame 101, a steel scaffolding plank 102, and a transmission assembly. The transmission assembly includes a fixing plate 103, a threaded seat 104, a rotating screw 105, a placement box 106, a limiting component, a rotating component, an installation component, and a partition plate 107. The limiting component includes a limiting slide 108 and a sliding frame 109. The rotating component includes a rotating seat 110, a rotating rod 111, a connecting rod 112, a rotating handle 113, and a limiting ring 114. The installation component includes a fixing frame 115 and an installation frame 116. This solution addresses the issue of a height difference between construction workers on the platform and those on the ground, which makes it difficult for ground personnel to pass tools or parts to the construction workers on the platform. Therefore, this solution can be used in situations where the transfer of tools or parts is necessary.

[0027] In this embodiment, the steel scaffolding 102 is installed on the load-bearing frame 101, which is composed of multiple trusses and heavy beams. The steel scaffolding 102 is cold-rolled from steel profiles and has anti-slip textures on its surface, allowing construction workers to carry out construction work on the steel scaffolding 102.

[0028] The fixed plate 103 is fixedly connected to the load-bearing frame 101 and located on one side of the load-bearing frame 101. The threaded seat 104 is connected to the fixed plate 103 through the limiting member and is located on one side of the fixed plate 103. The rotating screw 105 is connected to the fixed plate 103 through the rotating member and threadedly connected to the screw seat, and is located on the side of the fixed plate 103 near the threaded seat 104. The placement box 106 is connected to the threaded seat 104 through the mounting member and is located on one side of the threaded seat 104. The limiting member is disposed on the fixed plate 103 and connected to the threaded seat 104. The rotating member is disposed on the fixed plate 103 and connected to the rotating screw seat 104. A screw 105 is connected, and the mounting component is disposed on the threaded seat 104 and connected to the placement box 106. There are two fixing plates 103, which are welded to the load-bearing frame 101. The threaded seat 104 is connected to the fixing plate 103 via the limiting component, which provides connection support and directional limitation for the movement of the threaded seat 104. The rotating screw 105 is connected to the fixing plate 103 via the rotating component, which allows the operator to easily rotate the rotating screw 105. The rotating screw 105 is threadedly connected to the threaded seat 104. The thread of the rotating screw 105 and the limiting component control the thread... Under the directional limiting action of the seat 104, the rotating screw 105 can drive the threaded seat 104 to move up and down when it rotates. The placement box 106 is connected and fixed to the threaded seat 104 through the mounting member. The placement box 106 has a placement groove. The limiting member is set on the fixing plate 103 and connected to the threaded seat 104. The rotating member is set on the fixing plate 103 and connected to the rotating screw 105. The mounting member is set on the threaded seat 104 and connected to the placement box 106. This realizes the need for ground personnel to transmit power to construction personnel on the steel scaffolding 102. When passing tools or parts, ground personnel place the tools or parts in the placement box 106 and rotate the rotating component to drive the rotating screw 105 to rotate. Through the thread of the rotating screw 105 and the directional limiting effect of the limiting component on the movement of the thread seat 104, the rotating screw 105 can drive the thread seat 104 to move up and down when it rotates. The moving up and down movement of the thread seat 104 can drive the moving up and down movement of the placement box 106. Thus, after placing the tools or parts in the placement box 106, it is moved up and down to the construction personnel on the steel scaffolding 102, making it convenient for ground personnel to pass the tools or parts to the construction personnel on the steel scaffolding 102 for retrieval and use.

[0029] Secondly, the limiting slide 108 is fixedly connected to the fixed plate 103 and located on one side of the fixed plate 103; the sliding frame 109 is slidably connected to the limiting slide 108 and fixedly connected to the threaded seat 104, and located on the side of the limiting slide 108 close to the fixed seat. The limiting slide 108 is welded to the two fixed plates 103, and the sliding frame 109 is slidably connected to the limiting slide 108. The limiting slide 108 can provide connection support and directional limitation for the sliding of the sliding frame 109. The threaded seat 104 is welded to the sliding frame 109, so that the sliding of the sliding frame 109 can provide connection support and directional limitation for the movement of the threaded seat 104.

[0030] Meanwhile, the rotating seat 110 is fixedly connected to the fixed plate 103 and located on one side of the fixed plate 103; the rotating rod 111 is rotatably connected to the rotating seat 110 and fixedly connected to the rotating screw 105, and located on the side of the rotating seat 110 close to the rotating screw 105; the connecting rod 112 is fixedly connected to the rotating rod 111 and located on the side of the rotating rod 111 away from the rotating screw 105; the rotating handle 113 is fixedly connected to the connecting rod 112 and located on one side of the connecting rod 112; the limiting ring 114 is fixedly connected to the rotating rod 111 and located on the side of the rotating rod 111 close to the rotating seat 110. There are two rotating seats 110, and the two rotating seats 110 are welded to the corresponding two fixed plates 103. There are two rotating rods 111, which are rotatably connected to two corresponding rotating seats 110. The rotating seats 110 can connect, support, and limit the rotation of the rotating rods 111. A connecting rod 112 is welded to the upper rotating rod 111, and a rotating handle 113 is welded to the connecting rod 112. Thus, the operator can drive the rotating rod 111 on the connecting rod 112 to rotate by rotating the rotating handle 113. There are two limiting rings 114, which are welded to the two corresponding rotating rods 111. The limiting rings 114 limit the rotation within the rotating seats 110, and can prevent the rotating rods 111 from shifting or coming out of the rotating seats 110 when rotating within them.

[0031] Additionally, the fixing bracket 115 is fixedly connected to the threaded seat 104 and is located on one side of the screw seat; the mounting bracket 116 is fixedly connected to the fixing bracket 115 and the placement box 106 respectively, and is located on the side of the fixing bracket 115 near the placement box 106. The fixing bracket 115 is welded to the threaded seat 104 and has a mounting through hole. The mounting bracket 116 is welded to the placement box 106 and has a threaded hole. By aligning the through hole on the fixing bracket 115 with the threaded hole on the mounting bracket 116, the placement box 106 can be connected and fixed to the threaded seat 104 by bolts and move with the lifting and lowering movement of the threaded seat 104.

[0032] Finally, the partition plate 107 is fixedly connected to the placement box 106 and located on one side of the placement box 106. The partition plate 107 is welded into the placement box 106. The partition plate 107 can divide the space inside the placement box 106, thereby facilitating the operator to classify and store the tools or parts inside the placement box 106 for easy retrieval during subsequent use.

[0033] When using the steel truss lower chord connection joint construction platform of this embodiment, if ground personnel need to pass tools or parts to construction workers on the steel scaffolding 102, the ground personnel place the tools or parts in the placement box 106 and rotate the rotating component to drive the rotating screw 105 to rotate. Through the thread of the rotating screw 105 and the directional limiting action of the limiting component on the movement of the threaded seat 104, the rotating screw 105 can drive the threaded seat 104 to move up and down when it rotates. The moving up and down movement of the threaded seat 104 can drive the moving up and down movement of the placement box 106. Thus, by placing the tools or parts in the placement box 106 and moving it up and down to the construction workers on the steel scaffolding 102, it is convenient for ground personnel to pass the tools or parts to the construction workers on the steel scaffolding 102 for retrieval and use.
