Description

Technical Field

[0001] The present invention relates to the technical field of assembled steel structures, and in particular to a supporting device and a supporting method for assembled steel structures. Background Art

[0002] Steel structure refers to a structural form that can bear and transmit loads and is made of steel plates and hot-rolled, cold-bent or welded profiles connected by connectors; prefabricated steel structure buildings refer to steel structure components produced in factories and assembled and connected at the construction site.

[0003] H-shaped steel is the main column structure in the steel structure. When the steel structure is assembled on site, embedded parts need to be embedded before the H-shaped steel is installed. Due to the unevenness and inclination of the ground, the installation angle of the H-shaped steel is easily offset, which in turn causes deviations in the subsequent overall steel structure. The steel structure components are pre-produced, which makes it impossible to assemble normally on site. When the H-shaped steel is adjusted horizontally using the base, the connection status of the connecting bolts cannot be flexibly adjusted according to the inclination of the upper and lower layers of the base, which leads to insufficient contact between the connecting bolts and the upper and lower layers of the base. At the same time, when supported only by the base and H-shaped steel, the supporting strength is poor, and when used in different rings and different weather conditions, different parts of the H-shaped steel are subjected to different stress levels. Summary of the Invention

[0004] The problem solved by the present invention is to provide a supporting device and a supporting method for assembled steel structures, which solves the problem that H-shaped steel is the main column structure in the steel structure. When the steel structure is assembled on site, it is necessary to embed embedded parts and then install the H-shaped steel. Due to the unevenness and inclination of the ground, the installation angle of the H-shaped steel is easily offset, which in turn causes the subsequent overall deviation of the steel structure. The steel structure components are pre-produced, which makes it impossible to assemble normally on site. When the H-shaped steel is horizontally adjusted by the base, the connection status of the connecting bolts cannot be flexibly adjusted according to the inclination of the upper and lower layers of the base, which leads to insufficient contact between the connecting bolts and the upper and lower layers of the base. At the same time, when the support is only provided by the base and the H-shaped steel, the supporting strength is poor, and when used in different rings and different weather conditions, different parts of the H-shaped steel are subjected to different stress levels.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0015] Step 1: Install the embedded parts and the bottom mounting seat. The first nuts of the connecting mechanism are all in a loose state. Under the action of gravity, the limit cylinder rotates between the side plates through the rotating shaft, and the limit cylinder is always in a vertical state. After the installation of the bottom mounting seat is completed, tighten the first nut, place the spirit level on the top mounting seat, and move the adjusting ball at the bottom of the top mounting seat in the adjusting ball groove of the adjusting seat to adjust. Use the spirit level to adjust the top mounting seat to a horizontal state. At this time, pass the long rod bolt through the second mounting hole, the limit cylinder and the adjusting groove and connect them with the second nut, thereby achieving fixed installation of the top mounting seat, and then install the H-shaped steel to the top mounting seat through the connecting plate and bolts;

[0016] Step 2: Put the collar and ring plate on the H-shaped steel, and move the ring plate along the H-shaped steel through the H-shaped groove. Install different numbers of support legs into the T-shaped groove through T-shaped blocks, and the support plates at the bottom of the support legs are in contact with the ground. The H-shaped steel is supported and reinforced by the support legs and support plates.

[0017] The beneficial effects of the present invention are as follows: the bottom mounting seat and the embedded parts are installed, and the horizontality of the top mounting seat is adjusted by moving the adjusting ball in the adjusting ball groove of the adjusting seat at multiple angles between the bottom mounting seat and the top mounting seat, and then the adjusted top mounting seat is fixed to the support seat of the bottom mounting seat, thereby ensuring that the H-shaped steel installed on the top mounting seat is in a vertical state;

[0018] During the installation of the embedded parts and the bottom mounting seat, the first nuts of the connecting mechanism are in a loose state. Under the action of gravity, the limiting cylinder rotates between the side plates through the rotating shaft, and the limiting cylinder is always in a vertical state. After the bottom mounting seat is installed, tighten the first nut. At this time, the center of the limiting cylinder and the center of the second mounting hole are always in the same vertical straight line. The long rod bolt is passed through the second mounting hole, the limiting cylinder and the adjusting slot and connected with the second nut, thereby achieving fixed installation of the top mounting seat. At this time, ensure that the long rod bolt and the second nut are in a fit state with the top side of the top mounting seat and the bottom side of the limiting cylinder. Ensure that the long rod bolt and the second nut are tightly and firmly installed with the top mounting seat and the limiting cylinder;

Depending on the actual support and the stress conditions of the H-shaped steel, different numbers of support legs are installed, and support legs with different densities are installed in different locations to achieve partitioned support and reinforcement of the H-shaped steel.
