Description

Technical Field

[0001] This invention relates to the field of steel space frame installation, specifically to a temporary bolt ball support system for suspended steel space frames and its working method. Background Technology

[0002] Steel space frame structures, due to their rational stress distribution, structural stability, light weight, high rigidity, good overall effect, strong seismic resistance, and novel design, have become a representative roofing structure widely used in buildings such as airports, stadiums, and exhibition halls. Currently, there are two main methods for installing steel space frames: one is to assemble them in sections or as a whole on the ground and then hoist them into place; the other is to erect an operating scaffold and assemble the steel space frame symmetrically in a radial pattern, using supports mounted on the building's beams and columns as the starting point. Both methods require complex hoisting or lifting devices, resulting in high construction costs and significant difficulty. Summary of the Invention

[0003] The purpose of this invention is to provide a temporary support system for bolted balls in a suspended steel grid structure and its working method. This invention can provide stable and reliable support for the bolted balls and can accurately position the bolted balls without the need for complex jacking or hoisting devices, thereby improving construction efficiency and reducing overall construction costs.

[0004] The technical solution adopted in this invention is:

[0005] A temporary support system for bolted balls in a suspended steel space frame includes a support frame, a pad plate laid on top of the support frame, and support units distributed on the pad plate and located directly below the installation positions of each bolted ball. Each support unit includes a base plate with positioning crosshairs, a vertical cylinder fixed to the positioning center on the base plate, a screw rod inserted into the upper part of the vertical cylinder, an adjusting block threaded onto the screw rod and supported at the top of the vertical cylinder, a support block fixed to the upper end of the screw rod, a transition plate and a level on the vertical cylinder, and diagonal braces distributed around the vertical cylinder. The base plate is mounted on the pad plate via leveling bolts. The support block has a groove at its top positioning center that conforms to the lower contour of the bolted ball, and the groove contains positioning crosshairs. The diagonal braces employ a threaded telescopic structure, with the upper end hinged to the transition plate and the lower end connected to a clamp via a universal joint. The clamp includes two arc-shaped plates with adjustable spacing.

[0006] Preferably, the two arc-shaped plates of the clamp are a fixed arc-shaped plate and a movable arc-shaped plate, respectively. The movable arc-shaped plate is rotatably mounted on the end of the adjusting bolt, and the adjusting bolt is threaded onto the components of the clamp.

[0007] Preferably, the adjusting block is provided with a handle for easy operation.

[0008] Preferably, the level is mounted on the adapter plate.

[0009] Preferably, the diagonal brace is hinged to the adapter plate via a pivot.

[0010] Preferably, the vertical cylinder is welded and fixed to the base plate.

[0011] Preferably, the level is a bubble level.

[0012] Preferably, the three diagonal braces are evenly distributed around the vertical cylinder.

[0013] Preferably, the support frame is provided with protective components around its perimeter.

[0014] The working method of the above-mentioned temporary bolt ball support system for suspended steel space frame is as follows:

[0015] First, set up the support frame and base plate according to the load conditions, and set the positioning cross lines on the base plate directly below the installation position of each bolt ball. Set the size and quantity of the support unit according to the size of the steel grid frame and the size and quantity of the bolt balls.

[0016] Then install each support unit: First, align the positioning cross lines on the base plate and the pad plate. Then, install the base plate on the pad plate with the leveling bolts and level it with a level. Then, insert the screw into the upper part of the vertical cylinder and adjust the extension height of the screw by operating the adjusting block so that the positioning center of the positioning cross line on the groove is the same as the design elevation of the bottom of the bolt ball. Then, adjust the angle and length of the diagonal brace, the angle of the universal joint, and the spacing of the arc plate so that the arc plate is clamped on the steel pipe of the support frame.

[0017] Then place the bolt balls on the grooves, and install the web members and chord members until the starting frame is assembled and the steel space frame span forms a complete whole;

[0018] Once the steel space frame is completed and the steel space frame as a whole can maintain its self-stability through structural force, dismantle the entire system: first, operate the adjusting block to disengage the groove from the bolt ball and retract the screw to the appropriate height, remove the screw from the vertical cylinder, then adjust the spacing of the arc plate to disengage it from the steel pipe of the support frame, then loosen the leveling bolt, remove the bottom plate and vertical cylinder, and then gradually dismantle the support frame.

[0019] The beneficial effects of this invention are:

[0020] This invention provides vertical support and limiting for the bolt ball through grooves, screws, adjusting blocks, vertical cylinders, base plates, pads, and support frames, and provides stable diagonal bracing for the support unit through diagonal bracing rods. Therefore, it can provide stable and reliable support for the bolt ball and prevent its movement. At the same time, this invention also has positioning and leveling structures, which can accurately position the bolt ball. Therefore, this application can start assembling from all bolt balls on any side of the starting frame simultaneously and move towards the opposite direction. This changes the traditional method of assembling on the ground and then lifting and hoisting the whole assembly, which relies on the support as the starting point and radiating outwards. It eliminates the need for complex lifting or hoisting devices, significantly improves construction efficiency, reduces overall construction costs, and allows materials to be reused, saving resources.
