Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and more specifically, to an adjustable positioning jig for ground assembly of hangar space frame. Background Technology

[0002] A space frame structure is a spatial structure composed of multiple members connected at nodes in a specific grid pattern. Space frame structures are widely used due to their advantages such as low spatial stress, light weight, high stiffness, and good seismic performance. During the assembly of a space frame structure, a temporary support frame is required. Once the assembly is complete and the space frame structure has formed a stable load-bearing system, the temporary support frame is removed.

[0003] Chinese Patent No. CN219411911U provides an adjustable support frame for space frame assembly, comprising: a support platform including two adjusting plates and two opposing shaped bases, with both ends of each adjusting plate adjustablely mounted on the two shaped bases; a support assembly including multiple pipe sections coaxially and detachably mounted together, with the lower pipe section of the support assembly detachably mounted on the adjusting plates; a support component, mounted on the upper end of the support assembly via a threaded connection; and a leveling component, used to adjust the levelness of the support component, and installed between the support component and the support assembly. This invention solves the problem that existing support frames cannot adjust the height and horizontal position according to the size and structure of the space frame to be supported.

[0004] Currently, the existing adjustable positioning jigs used for ground assembly of hangar space frames can be raised, but if the height or position of the jig is found to be unsuitable during the assembly process, it cannot be adjusted further. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable positioning jig for ground assembly of hangar space frame, which aims to improve the problem that the height and position of the adjustable positioning jig for ground assembly of hangar space frame cannot be adjusted during the assembly process under normal circumstances.

[0006] This utility model is implemented as follows:

[0007] This utility model provides an adjustable positioning jig for ground assembly of hangar space frame, including a fixed structure and a height adjustment structure fixed to the top of the fixed structure. The fixed structure includes a fixed plate and a transverse sliding member, which is slidably connected inside the fixed plate. The height adjustment structure includes a height adjustment member and an auxiliary support member, which is fixed to the top of the height adjustment member. The height adjustment member includes a first rotating block, which is fixed to the top of the transverse sliding member. A first rotating arm is rotatably connected to one side of the first rotating block, a connecting block is rotatably connected to one side of the first rotating arm, a second rotating arm is rotatably connected to one side of the connecting block, a second rotating block is rotatably connected to one side of the second rotating arm, and a connecting rod is rotatably connected to one side of the connecting block. A connecting block is fixed to the end of the connecting rod, and a second lead screw is threadedly connected inside the connecting block. A second rotating handle is fixed to the end of the second lead screw.

[0008] In one embodiment of this utility model, a fixing hole is provided on the top of the fixing plate, and a support plate is fixed on the top of the fixing plate.

[0009] In one embodiment of this utility model, a lead screw is threadedly connected inside the support plate, and a rotating handle is fixed at one end of the lead screw.

[0010] In one embodiment of the present invention, the transverse component includes a sliding plate, which is slidably connected inside the fixed plate. A groove is provided on the top of the sliding plate, and a slider is slidably connected inside the groove.

[0011] In one embodiment of this utility model, a support frame is fixed to the top of the slider, and a limit rod is fixed to the top of the support frame.

[0012] In one embodiment of this utility model, the auxiliary support includes a lifting block, which is fixed to the top of the rotating block two, and a threaded column is threaded to the top of the lifting block.

[0013] In one embodiment of this utility model, a rotating sleeve is fixed to one side of the threaded rod, and an anti-slip pad is fixed to the top of the lifting block.

[0014] In one embodiment of this utility model, a sliding sleeve is slidably connected to one side of the lifting block, and a ball is rotatably connected inside the sliding sleeve.

[0015] The beneficial effects of this utility model are as follows: The adjustable positioning jig for hangar space frame ground assembly obtained by the above design can be used to adjust the jig position during the assembly process. First, the screw rod is moved upward by rotating the rotating sleeve, which in turn moves the sliding sleeve upward and allows the ball bearing to support the space frame instead of the anti-slip pad. Then, the screw rod is moved by rotating the first handle at different positions, thereby moving the support frame and adjusting the jig position. If the height of the jig needs to be adjusted, the second handle is rotated, which drives the connecting block to move in opposite directions, thereby changing the angle between the first and second rotating arms and adjusting the height of the lifting block. Then, the sliding sleeve is reset, allowing the space frame to fall back onto the anti-slip pad after the height adjustment. Attached Figure Description

[0023] Example

[0024] Please see Figure 1-4 This utility model provides a technical solution: an adjustable positioning frame for ground assembly of hangar space frames, including a fixed structure 100 and a height adjustment structure 200 fixed to the top of the fixed structure 100. The fixed structure 100 includes a fixed plate 110 and a transverse sliding member 120, which is slidably connected inside the fixed plate 110. The height adjustment structure 200 includes a height adjustment member 210 and an auxiliary support member 220, which is fixed to the top of the height adjustment member 210. The height adjustment member 210 includes a rotating block 211, which supports a rotating arm 212 and is fixed to the top of the transverse sliding member 120. A rotating arm 212 is rotatably connected to one side of a rotating block 211. A connecting block 213 is rotatably connected to one side of a rotating arm 212, which serves as a transition connection. A rotating arm 214 is rotatably connected to one side of a connecting block 213. A rotating block 215 is rotatably connected to one side of a rotating arm 214. The rotating block 215 is fixed to the bottom of a lifting block 221. A connecting rod 216 is rotatably connected to one side of a connecting block 213. A mating block 217 is fixed to the end of the connecting rod 216. A lead screw 218 is threadedly connected inside the mating block 217. The lead screw 218 has two types of threads with opposite helical directions. A rotating handle 219 is fixed to the end of the lead screw 218.

[0025] Please see Figure 1-3The top of the fixed plate 110 has a fixing hole 111, and a support plate 112 is fixed to the top of the fixed plate 110. A lead screw 113 is threaded inside the support plate 112, and a handle 114 is fixed to the end of the lead screw 113. The handle 114 facilitates the rotation of the lead screw 113. The transverse component 120 includes a sliding plate 121, which allows the support frame 124 to move left and right. The sliding plate 121 is slidably connected inside the fixed plate 110. A slide groove 122 is provided on the top of the sliding plate 121, and a slider 123 is slidably connected inside the slide groove 122. The slider 123 allows the support frame 124 to move back and forth. The support frame 124 is fixed to the top of the slider 123 and slides above the fixed plate 110. A limit rod 125 is fixed to the top of the support frame 124, which restricts the movement direction of the lifting block 221.

[0026] Please see Figure 1 and Figure 3-4 The auxiliary support 220 includes a lifting block 221, which is fixed to the top of the rotating block 215. A threaded column 222 is threaded to the top of the lifting block 221. The threaded column 222 can move against the sliding sleeve 225 by rotating. A rotating sleeve 223 is fixed to one side of the threaded column 222. An anti-slip pad 224 is fixed to the top of the lifting block 221. The anti-slip pad 224 serves to increase friction and protect the paint on the outer surface of the mesh frame. A sliding sleeve 225 is slidably connected to one side of the lifting block 221. A ball bearing 226 is rotatably connected inside the sliding sleeve 225. The ball bearing 226 rotates so that the mesh frame will not dry rub against the sliding sleeve 225 when the frame moves.

[0027] Specifically, the working principle of the adjustable positioning jig for ground assembly of the hangar space frame is as follows: First, the jig is fixed to the ground according to the preset points, and the fixing plate 110 is fixed to the ground by bolts passing through the fixing holes 111. Then, the assembly of the space frame can begin. During assembly, if the height of the jig needs to be adjusted, simply rotate the second handle 219, causing the second lead screw 218 to rotate and drive the two connecting blocks 217 to move in opposite directions. This changes the angle between the first rotating arm 212 and the second rotating arm 214, thereby adjusting the height of the lifting block 221. When the jig needs to be moved laterally, first rotate the rotating sleeve 223 using a tool, causing the lead screw 222 to rotate, thus lifting the sliding sleeve. 225 moves upward, causing the ball bearing 226 to replace the anti-slip pad 224 in supporting the net frame. Then, the corresponding handle 114 is rotated. Assuming the frame needs to move to the left, firstly, the handle 114 is used to prevent the front and rear lead screws 113 from contacting the support frame 124. Then, the left handle 114 is rotated to move the lead screw 113 away from the support frame 124. Then, the right handle 114 is rotated to move the support frame 124 by rotating the lead screw 113, thereby achieving the purpose of moving the frame position. Then, all the lead screws 113 are pressed against the support frame 124. Then, the screw column 222 is reset, causing the sliding sleeve 225 to reset, so that the lifting block 221 supports the net frame through the anti-slip pad 224, thus completing the movement of the frame.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
