Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a supporting vertical bar and steel truss bottom formwork reinforcement component in building construction. Background Technology

[0002] In building construction, the steel truss bottom formwork serves as the bottom template for concrete pouring, providing a flat and solid supporting surface for the concrete. When the concrete structure is subjected to external forces, the supporting vertical bars can work together with the concrete to bear part of the tensile or compressive forces, thereby improving the overall load-bearing capacity and seismic performance of the structure.

[0003] Supporting vertical ribs are typically used in conjunction with steel truss bottom formwork to ensure that concrete forms the required shape and size during pouring. Common methods for fixing the supporting vertical ribs to the steel truss bottom formwork include bolting or direct pouring together. Due to the small contact area between the supporting vertical ribs and the steel truss bottom formwork, a reinforcing component for supporting vertical ribs and steel truss bottom formwork in construction has been designed to provide reinforcement. This component uses a combination of thickened perforated parts and perforated angle iron, which not only provides additional support to the inner cavity of the supporting vertical ribs but also increases the connection force between the supporting vertical ribs and the steel truss bottom formwork, thus strengthening the connection between them.

A small-diameter nut 9 is attached to the surface of the small-diameter bolt 8, and two rubber washers 10 are slidably connected to it. The two rubber washers 10 are located on the front side of the thickened hollow part 3 and the rear side of the supporting vertical rib 2, respectively. By setting the rubber washers 10, the surface of the small-diameter bolt 8 and the thickened hollow part 3 can be protected by buffering force, which can prevent the surface of the thickened hollow part 3 from being worn.

Horizontal supporting ribs 12 are welded to the bottom of both sides of the supporting vertical rib 2. Example 2

[0025] Figure 1-5 This invention illustrates a supporting vertical rib and steel truss bottom formwork reinforcement assembly in building construction according to an embodiment of the present invention. The assembly includes: a supporting vertical rib 2 disposed at the top of the steel truss bottom formwork 1; a thickened perforated part 3 welded to the inner cavity of the supporting vertical rib 2; a perforated angle iron 4 disposed at the top of the steel truss bottom formwork 1; a positioning bolt 5 threadedly connected to the inner cavity of the perforated angle iron 4; the perforated angle iron 4 being fixedly connected to the steel truss bottom formwork 1 by the positioning bolt 5; a large-diameter bolt 6 threadedly connected to the inner cavity of the perforated angle iron 4; the rear surface of the large-diameter bolt 6 penetrating through the thickened perforated part 3 to the rear side of the supporting vertical rib 2 and threadedly connected with a large-diameter nut 7; a small-diameter bolt 8 threadedly connected between the thickened perforated part 3 and the supporting vertical rib 2; the rear surface of the small-diameter bolt 8 penetrating through the supporting vertical rib.

Then, the user uses positioning bolts 5 to fix the perforated angle iron 4 to the top of the steel truss bottom mold 1, and uses large-diameter bolts 6 to fix the supporting vertical rib 2, the thickened hollowed-out part 3 and the perforated angle iron 4, thereby providing an anchoring reinforcement force between the supporting vertical rib 2 and the steel truss bottom mold 1. Then, the user uses small-diameter bolts 8 and small-diameter nuts 9 to further reinforce the connection between the thickened hollowed-out part 3 and the supporting vertical rib 2. This provides additional support to the inner cavity of the supporting vertical rib 2 and increases the connection force between the supporting vertical rib 2 and the steel truss bottom mold 1, thus providing a reinforcing reinforcement force between the supporting vertical rib 2 and the steel truss bottom mold 1, making the connection between the supporting vertical rib 2 and the steel truss bottom mold 1 more secure.

[0027] In summary, the supporting vertical ribs and the steel truss bottom formwork reinforcement components in this construction, through the combination of thickened hollow parts 3 and perforated angle irons 4, can not only provide additional support to the inner cavity of the supporting vertical ribs 2, but also increase the connection force between the supporting vertical ribs 2 and the steel truss bottom formwork 1. This achieves the purpose of reinforcing the connection between the supporting vertical ribs 2 and the steel truss bottom formwork 1, making the connection between the supporting vertical ribs 2 and the steel truss bottom formwork 1 more secure.
