1. The square pipe frame used in the present invention has a simple structure, is easy to obtain materials, has a small processing volume, and saves costs.

2. According to the thickness of the plate, it can be processed into a square tube frame with a corresponding height, which can be used repeatedly and is convenient and quick to install.

3. The square tube frame can also be used as a footing place for the operator when walking, so as to avoid stepping on the steel bar directly.

4. It is convenient to control the thickness of the floor slab and avoid the phenomenon of insufficient or over-thickness of the floor slab.

5. A large number of steel bar stools are saved in the floor part constructed by the utility model, which has good economic benefits.

6. For projects with many construction sections on the same floor, about one-half of the quantity can be processed and produced in the flow operation for plane turnover, and then the turnover between different floors.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

As shown in Figures 1-4, the present embodiment provides a square pipe frame support device for controlling the thickness of concrete slabs by a suspension method, which is installed on the tie-up steel reinforcement frame on the floor formwork. The square pipe frame support device includes: A square tube frame 1, the square tube frame 1 includes a rectangular frame 2 and several pairs of supporting feet 3 vertically arranged on the lower end face of the rectangular frame 2, the supporting legs 3 are made of φ12 or φ14 steel bars; the rectangular frame 2 is placed horizontally On the upper end face of the reinforced steel frame that has been bound, the ends of the supporting feet 3 pass through the reinforced frame and are arranged on the upper end face of the floor formwork, and the height of the square pipe frame 1 is equal to the thickness of the concrete slab to be poured; The intersections with the square tube frame 1 are firmly tied point by point with iron wires, and the 4 sides of the negative ribs of the plate are close to the bottom of the rectangular frame 2.

Please refer to FIG. 1 to FIG. 3 , the rectangular frame 2 includes two rectangular tubes 201 with the same length and a plurality of tie rods 202 , the rectangular tubes 201 are arranged in parallel, and the two ends and the middle of the rectangular tube are welded with tie rods 202 , the tie rod 202 and the rectangular tube 201 are perpendicular to each other, the tie rod 202 can be a short square tube or a steel bar above φ12, the spacing between the two rectangular tubes 201 is 350-450mm, and the spacing between the tie rods 202 is 350-450mm; The supporting feet 3 are symmetrically arranged on the lower end surfaces of the two rectangular tubes 201 , and the distance between two adjacent pairs of supporting feet 3 is 350-450 mm.
