Examples
Referring to fig. 1, the steel pipe frame for construction according to the present embodiment includes a vertical rod 100, a horizontal rod 200, and an overhanging diagonal brace 300;
the vertical rods 100 and the horizontal rods 200 are arranged on the outer side of the floor in a crossed manner to form a vertical surface formwork surrounding the floor, and fine wire netting is laid on the vertical surface formwork; a horizontal fixed support 400 is arranged on the floor level corresponding to the vertical face template, and the horizontal fixed support 400 is used for forming an overhanging support part 410 by paying off the floor level; the bottom of the vertical face template is fixedly connected with the overhanging support part 410; the cantilever inclined strut 300 comprises inclined strut steel 310 and a steel embedded plate 330, and the steel embedded plate 330 is embedded in the next floor level of the corresponding floor of the vertical face template;
the upper end of the diagonal bracing steel 310 is fixedly connected with the overhanging support part 410, and the other end is fixedly connected with the steel buried plate 330; the included angle between the diagonal bracing steel 310 and the floor layer is 30-60 degrees, so that the stress of the diagonal bracing steel 310 is ensured to be axial force as much as possible, and the bearing capacity of the diagonal bracing steel 310 is improved.
All the horizontal rods 200 are arranged in parallel, and the distance between every two adjacent horizontal rods 200 is 450-550 mm, so that the number of the horizontal rods 200 can be reduced while subsequent construction is facilitated, and the construction period and the construction cost are reduced.
In this embodiment, the bracing steel 310 is further provided with a reinforcing steel 350 made of L50 × 5 type angle steel on the side facing the floor level corresponding to the vertical formwork. One end of the reinforcing steel 350 is fixedly connected with the diagonal bracing steel 310, and the other end is connected with the cantilever support part 410. The included angle between the reinforcing steel 350 and the inclined strut steel 310 is 30-60 degrees, good axial stress is kept, and the risk of increasing radial stress is avoided.
In this embodiment, a longitudinal cross brace 510 is further disposed in the vertical face formwork; every four adjacent vertical rods 100 form a group of longitudinal support groups; at least one longitudinal cross brace 510 is arranged in each longitudinal brace group; the longitudinal cross brace 510 comprises two cross braces, one end of each brace is connected to the vertical rod 100 on one side of the longitudinal support group, and the other end of each brace is connected to the vertical rod 100 on the other side of the longitudinal support group. The vertical cross braces 510 can prevent the vertical face formwork from deforming due to the dislocation of the vertical rod 100, and the deformation increase easily causes the stress balance of the whole vertical face formwork to be damaged and then collapse.
Specifically, a horizontal cross brace is also arranged in the vertical face template; the horizontal cross braces are arranged at the corner positions of the vertical face template corresponding to the corners of the floors; the horizontal scissors are braced against the horizontal fixed support 400.
Horizontal cross braces function similarly to longitudinal cross braces 510 and may also provide additional support to avoid vertical form distortion.
In order to increase the connection strength between the vertical face formwork and the overhanging support part 410, a steel wire rope is bound at the connection part between the vertical face formwork and the overhanging support part 410. The steel wire rope can be supplemented as required, and can be directly cut off when being disassembled.
Referring to fig. 2, the horizontal fixing support 400 includes a plurality of horizontal cantilever steels 420 made of i-shaped steels arranged in parallel; the horizontal cantilever steel 420 is fixed to the floor level by U-shaped anchor bolts 430. Specifically, the U-shaped anchor bolt 430 includes a transverse connecting rod 431 and vertical clamping rods 433 disposed at both sides of the transverse connecting rod 431, and an opening is formed at a side corresponding to the transverse connecting rod 431. The transverse connecting rod 431 is embedded in the floor slab, the opening is exposed, so that the horizontal cantilever steel 420 is installed in the opening, and a steel pressing plate 437 is further arranged above the horizontal cantilever steel 420 at the opening to fix the position of the horizontal cantilever steel 420. In order to avoid the horizontal displacement of the horizontal cantilever steel 420, hard wood wedges 435 are arranged on two sides of the horizontal cantilever steel 420, one side of each hard wood wedge 435 is abutted to the horizontal cantilever steel 420, and the other side of each hard wood wedge 435 is abutted to the vertical clamping rod 433.
The steel pipe support body for the building can be made into a formwork support of a floor (such as a large brim) with a small bottom layer and a large roof through the overhanging structure, can meet the requirements on rigidity, strength and stability, and provides a safe operation platform for constructing floors with a small bottom layer and a large roof, such as the large brim. The design of two bracing can effectively turn into the axial force of steel shotcrete with the atress to increase intensity improves the security performance.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
