Description

Large-span assembled steel bar support

Technical Field

The utility model belongs to the field of building construction, and relates to a large-span assembled steel bar bracket which is used for erecting multi-layer steel bars of a base plate.

Background

At present, when an ultra-thick foundation slab is constructed, a plurality of layers of bottom ribs, a plurality of layers of temperature ribs and a plurality of layers of gluten are generally designed due to the large thickness of the slab (the thickness of part of the engineering is 7 m) and the deep depth. In order to meet the requirements of supporting and binding temperature bars and gluten, a special steel bar support is generally designed by steel sections, and the steel bar support consists of upright posts, temperature bar beams, gluten beams, scissor supports and the like. The traditional steel bar bracket is formed by fully welding channel steel, H-shaped steel and angle steel, the distance between the single steel bar brackets is mostly 2 x 2m, and the steel bar bracket is inconvenient to turn and lay due to the fact that the weight is light, the quantity of the steel bars is large, the hoisting operation task is heavy, the welding amount is large, the labor investment is large, the construction period is long and the distance between the upright posts is small.

Aiming at the problems, the utility model discloses a large-span assembled steel bar bracket in order to accelerate the erection speed of the steel bar bracket, facilitate the laying and binding of steel bars, reduce the exposure time of a deep pit of a large bottom plate and accelerate the concrete forming of the whole bottom plate.

Disclosure of Invention

The utility model belongs to the field of building construction, and relates to a large-span assembled steel bar bracket, which is characterized in that: the H-shaped steel is used as a main upright, the supporting plates and the connecting plates are welded at the corresponding heights on the upright, the middle cross beam H-shaped steel is connected with the connecting plates by high-strength bolts, the X-direction cross beam is welded with the connecting plates at the tops of the upright, the Y-direction cross beam is connected with the X-direction cross beam by high-strength bolts through the connecting plates, and the angle steel scissors stay connects the upright and the middle cross beam into a whole through welding.

The upright post is connected with the middle transverse beam through a high-strength bolt, the upright post is connected with the X-direction face transverse beam through a welding, and the X-direction face transverse beam is connected with the Y-direction face transverse beam through a high-strength bolt.
