Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a steel frame beam H-shaped steel positioning and adjusting support device acting on the bottom of the beam. Background Art

[0002] As land prices continue to rise, the design of super-high-rise housing buildings is becoming more and more common. As a relatively new structural form, steel beams are increasingly used in structural construction. However, due to the short development time of technology, the current steel beam construction technology is relatively elementary and primitive. Therefore, there is an urgent need to further optimize and standardize the construction of steel beams.

[0003] Usually, during the construction of steel beams, a tower crane or a crane is required to lift and position the H-shaped steel in the structure. When it is hoisted into the beam, the support point of the steel beam is usually the stirrups of the beam column or directly in contact with the bottom of the aluminum formwork. The steel beam must be simply welded and fixed before the tower crane hook can be released, which takes up a long time of tower crane use time. At the same time, due to the need for welding, it will more or less cause certain damage to the structural stirrups or aluminum formwork. In addition, due to the lack of steel beam construction technology, its positioning and elevation control technology is still blank in the industry. Therefore, in view of the above problems, it is necessary to design a steel beam H-shaped steel positioning and adjustment support device to fill the technical gap. Utility Model Content

[0004] The purpose of the utility model is to provide an H-shaped steel positioning and adjustment support device for a steel frame beam acting on the bottom of the beam, so as to solve the problem that the steel frame beam takes up too much tower crane use time during hoisting and positioning, reduce damage to structural stirrups or aluminum formwork, and at the same time fill the industry gap in steel frame beam positioning and elevation control technology during steel frame beam construction.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A steel frame beam H-shaped steel positioning and adjustment support device acting on the bottom of the beam, characterized in that: it includes a bracket, an adjustment screw supporting the bracket and a long rod torque wrench; the bracket is composed of a blocking component and a support limiting rib; the blocking component adopts 8# channel steel, the channel steel length is 10cm, and 2 support limiting ribs are symmetrically arranged on both sides of the blocking component, and the support limiting ribs adopt φ8 smooth round steel bars; a connecting nut is arranged at the bottom of the blocking component, and the connecting nut is connected to the adjusting screw.

[0007] The adjusting screw is provided with threads that enable the nut A and the nut B to slide up and down. The lowermost end of the adjusting screw is provided with an adjusting screw head, and the diameter of the adjusting screw head is smaller than the diameter of the adjusting screw.

[0008] The long-rod torque wrench comprises an adjusting bolt head, a rod body and a torsion rod body; the adjusting bolt head and the torsion rod body are connected through the rod body.

[0009] Preferably, the blocking member is connected to the supporting limiting rib by welding.

[0010] Preferably, one end of the connecting nut is welded to the blocking component, and the other end is slidably connected to the adjusting screw.

[0011] Preferably, the nut A is located above the nut B, and the adjusting screw is slidably connected to the nut A and the nut B.

[0012] Preferably, the adjusting screw head is welded to the adjusting screw, the cross section of the adjusting screw head is hexagonal, and the outer diameter thereof is adapted to the inner diameter of the adjusting bolt head.

[0013] Preferably, the adjusting bolt head is welded to the rod body, and the rod body is welded to the torsion rod body; and anti-slip thread patterns are provided at both ends of the torsion rod body.

[0014] Compared with the prior art, the utility model has the following characteristics and beneficial effects:

[0015] 1. This application is mainly aimed at the possible displacement and sinking of steel beams during construction, which in turn affects the stress effect of H-shaped steel, causing the displacement of electromechanical pipelines passing through steel beams and the poor binding effect of steel beam reinforcement, filling the gap in the H-shaped steel lifting support method in steel beam construction.

[0016] 2. The present application overcomes the shortcomings of the prior art that H-beams are mainly installed by tower cranes, and the hooks for installing the steel beams can only be loosened after reinforcement by welding of steel bars, which takes up a lot of tower crane time, and the welding reinforcement measures are cumbersome, which seriously affects the efficiency, and the height of the steel beam cannot be adjusted at all after welding. By using the present application, other operations can be carried out only after the tower crane has installed the steel frame to the position of the steel beam, which solves the problem of taking up too much tower crane time. At the same time, the steel frame can be in a suitable position without welding to position the supporting steel bars, which improves construction efficiency and reduces damage to the supporting steel bars. After positioning, further adjustments can be made by adjusting bolts to further refine the adjustment of the steel frame.

[0017] 3. The long-bar torque wrench can be used for adjustment under the beam, eliminating the problem of inconvenient operation caused by the small working space in the formwork, reducing the working time in the formwork, and is convenient and quick.

[0018] The utility model can be widely used in the steel frame beam H-shaped steel hoisting construction. BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting screw head 6 is provided at the lower end of the adjusting screw 3. The diameter of the adjusting screw head 6 is smaller than the diameter of the adjusting screw 3. The adjusting screw head 6 is welded to the adjusting screw 3.
