Technical Field

[0002] In the construction of spatial steel structures, the rigidity of the structure has not yet been formed during the installation process and cannot withstand its own and external loads. A temporary support frame needs to be set up during the installation process. For steel structure beams whose spatial position is not horizontal, conventional construction requires welding corbels on the frame to make the support surface fit with the upper steel structure. However, the welding operation involves the problem that the angle cannot be adjusted after the welding is completed. In the case of improper welding or large errors in the installation of the upper steel structure, the support surface cannot fit well with the upper steel beam, which will result in poor force effect. In addition, the on-site welding workload is large and the welding quality is difficult to guarantee.

[0003] The current publication number is CN116335438A, which is a support frame for large-span beams and its construction method. The support frame includes: a base and a support assembly connected to the top of the base in a height-adjustable manner for supporting the large-span beam; the support assembly includes a jack vertically connected to the top of the base and a support plate horizontally connected to the top of the jack.

[0004] Although the above solution has many benefits, it also has the following defects: the device provides one-way angle adjustment. Although it improves the connection accuracy and can be reused, the connection method of the device can only be adjusted in one direction. Both ends of the device are bolted, and the positioning requirements are high. There may be problems with installation in the horizontal direction. It only has a connection effect and cannot bear force, so the effect of use is not very good. Utility Model Content

Both ends of the device are bolted, the positioning requirements are high, and there may be problems with the horizontal installation, which makes the use effect not very good.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an engineering universal support structure that applies pre-tightening force through high-strength bolts, comprising two rotating bases, a connecting platform and a plurality of high-strength bolt bodies, the two rotating bases and the connecting platform are fastened together by a plurality of high-strength bolt bodies, long arc grooves and circular grooves are provided on both sides of the two rotating bases, the rotating base is adjustable in both directions, and is suitable for connection problems between supporting surfaces and supported surfaces at any angle during construction, without the need for on-site welding, the connecting platform and the rotating base are made of low-alloy high-strength structural steel, and the high-strength bolt body is made of . grade diameter M.

[0008] Preferably, the four side plates are each provided with eight threaded slots, the eight threaded slots are grouped into four, and each group of threaded slots is symmetrical up and down, and the high-strength bolt body is adapted to the threaded slots.

[0009] Preferably, several of the high-strength bolt bodies pass through two long arc grooves and two circular grooves respectively and are threadedly connected to the connecting platform. The connecting platform can rotate along the path direction of the long arc groove. The friction force can be calculated based on the pre-tightening force of the high-strength bolt and the friction coefficient between the rotating base and the connecting platform.
