Technical Field

[0001] This utility model relates to the field of auxiliary equipment for building structure construction, specifically a multi-dimensional adjustment and positioning device for the lower chord ball node of a space frame. Background Technology

[0002] A space frame is a spatial structure composed of multiple members connected at nodes in a specific grid pattern. It has advantages such as low spatial stress, light weight, high rigidity, and good seismic performance. However, traditional space frame construction involves a large amount of assembly work. Currently, assembly positioning is achieved using a total station for surveying and setting up temporary supports to fix the lower chord spheres within the space frame. This method requires the temporary supports to be cut and adjusted according to the sphere's elevation, resulting in low construction efficiency and unreliable construction accuracy.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-4 As shown, this utility model provides a multi-dimensional adjustment and positioning device for the lower chord ball nodes of a space frame, including an installation track 1, a sliding track 11 fixedly mounted on the installation track 1, a sliding platform 12 slidably mounted on the sliding track 11, a base 2 fixedly mounted on the top of the sliding platform 12, and an adjustable frame mounted on the upper surface of the base 2. It is worth noting that the number of adjustable frames used is determined according to the number of lower chord balls 31 of the space frame. Figure 1 As shown in the diagram, the adjustable frame includes a column 21, on which a vertically arranged movable column 22 is movably inserted. A screw 23 is threaded into the inside of the movable column 22. The bottom of the screw 23 rotatably passes through the upper end of the base 2. A placement plate 3 is fixedly provided on the top of the movable column 22. A lower chord ball 31 is provided at the center of the upper surface of the placement plate 3. A positioning component is provided on the upper surface of the placement plate 3 at the edge of the lower chord ball 31.

[0021] The positioning component includes a gear ring 32, which is rotatably disposed inside the placement plate 3. Three equally spaced drive gears 34 are rotatably disposed inside the placement plate 3 near the gear ring 32. The drive gears 34 are meshed and connected to the gear ring 32. A toothed plate 33 is movably inserted into the side wall of the placement plate 3 near the drive gears 34. One end of the toothed plate 33 is meshed and connected to the drive gears 34 inside the placement plate 3. A connecting rod is fixedly disposed at one end of the toothed plate 33 on the placement plate 3. A baffle 35 is fixedly disposed at the end of the connecting rod. A wedge-shaped positioning block 36 is disposed on the side of the baffle 35 facing the lower chord ball 31.

[0022] The base 2 is internally fixedly equipped with a first motor 24. The output end of the first motor 24 is coaxially fixed on the lead screw 23. The first motor 24 mainly provides power for the rotation of the lead screw 23, making it convenient for operators to control.

[0023] The lower surface of the placement plate 3 is fixedly provided with a vertically arranged limiting rod 25 directly above the column 21. The bottom of the limiting rod 25 is movably inserted into the column 21. The limiting rod 25 limits the movable column 22, preventing it from rotating, thereby allowing the movable column 22 to move directly up and down.

[0024] A fixing block 13 is fixedly provided on the side wall of the sliding platform 12. A positioning bolt 14 is inserted into the fixing block 13. The end of the positioning bolt 14 can pass through the fixing block 13 and be inserted into the side wall of the mounting track 1. The positioning bolt 14 can fix the position of the sliding platform 12 and the device above it on the mounting track 1, and accurately position the lower chord ball 31.

[0025] A second motor 39 is fixedly installed on the lower surface of the placement plate 3 near one of the drive gears 34. The output end of the second motor 39 is coaxially fixed at the center of the drive gear 34. The second motor 39 can conveniently provide power to rotate the drive gear 34, making it convenient for operators to operate.

[0026] The upper surface of the placement plate 3 is fixedly provided with three ring-shaped support blocks 37. The support blocks 37 have arc surfaces that correspond to the lower string ball 31. The back of the support blocks 37 is fixedly provided with a long rod 38 that movably passes through the baffle 35. The ring-shaped support blocks 37 can support the lower string ball 31 and limit its bottom to a certain extent, so as to avoid the lower string ball 31 shaking when placed, which would affect the use of the device.

[0027] Working principle: During use, the upper base 2 and the placement plate 3 can be moved laterally on the installation rail 1 and the sliding rail 11 by the sliding platform 12. Adjustment is made according to the position of the lower chord ball 31. After the base 2 is moved to the target position, it is fixedly connected to the installation rail 1 by the positioning bolt 14, so that the sliding platform 12 is fixed at the target position.

[0028] Then, the first motor 24 directly drives the lead screw 23 to rotate. At this time, since the lead screw 23 is threaded in the movable column 22, but the bottom of the lead screw 23 is limited to the base 2, the movable column 22 with the lead screw 23 threaded in it will be driven to adjust the vertical height. At this time, the position of the lower string ball 31 set on the placement plate 3 will be accurately raised, realizing the accurate positioning of the height of the lower string ball 31.

[0029] Before positioning the lower spool 31, the second motor 39 starts and drives the drive gear 34 fixed thereto to rotate. At this time, the gear ring 32 and gear plate 33 meshing with the drive gear 34 work together. The gear plate 33 will be driven to move towards the inside of the placement plate 3. At this time, the baffle 35 and positioning block 36 fixed on the gear plate 33 will approach the lower spool 31. During this process, the rotation of the gear ring 32 will drive the other two meshing drive gears 34 to rotate. At this time, the other two drive gears 34 will drive the meshing gear plate 33 to move towards the inside of the placement plate 3. Therefore, the positioning blocks 36 on the three baffles 35 on the placement plate 3 move towards the lower spool 31 at the same time. The wedge-shaped positioning block 36 will directly contact it and clamp and position it under the joint action of the three positioning blocks 36.

[0030] After the lower chord ball 31 is positioned, the remaining members of the space frame are installed. After the space frame is detached from the positioning assembly, the second motor 39 directly drives the drive gear 34 to rotate in the opposite direction, directly controlling the positioning block 36 to detach from the lower chord ball 31 and cancel its positioning.

[0031] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
