In order to achieve the above purpose, the technical scheme adopted by the present utility model is a cast-in-place concrete pavement pouring formwork, including: formwork panel 6, movable support rod 2 and steel back corrugated support bar 5; The bottom of the template panel 6) is welded with a steel back corrugated support bar 5, and the steel back corrugated support bar 5 is a slot for installing the movable support rod 2; one side of the template panel 6 is provided with a socket 1, and the other side is provided with a socket 1. There are socket joints 4; each formwork panel 6 is connected with socket joints 4 through socket holes 1 to form the main body of the pavement pouring formwork; the bottom of the main body of the pavement pouring formwork is welded with a right-angle positioning plate 3, and the right-angle positioning plate 3 is connected with the pouring base surface contact.

Further, a steel sleeve is provided in the slot for installing the movable support rod 2, and the movable support rod 2 is slidably connected with the steel sleeve; the bottom of the movable support rod 2 is provided with a threaded base, and the base is in contact with the support surface. Carry out lateral stability support for the main body of the pavement pouring formwork. A rubber pad is added between the movable support rod 2 and the steel sleeve to prevent slippage.

Further, the main body of the road pouring formwork is made of aluminum alloy.

Further, the right-angle positioning plate 3 is L-shaped, the vertical section of the right-angle positioning plate 3 is parallel to the formwork panel 6, and the horizontal section of the right-angle positioning plate 3 is provided with holes, which can be assisted by expansion bolts and the pouring foundation surface. The connection is fixed to increase the stability of the cast-in-place concrete pavement formwork.

Compared with the prior art, the present invention has the following beneficial effects.

1. The material of the utility model is simple, easy to manufacture, and easy to operate. Four movable support rods are provided, so that it is not easy to deform or run out of molds during use.

2. The utility model can effectively ensure the continuous construction operation, less labor is required for setting up the formwork, and the construction speed is fast.

3. High recycling value. After the aluminum formwork is scrapped, when the residual value of the waste treatment is high, the average cost advantage is obvious, and the low carbon emission is reduced. All materials of the aluminum formwork system are renewable materials, in line with the national regulations on energy conservation, environmental protection, low carbon and emission reduction of construction projects.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail:

As shown in Figure 1-3, a new type of cast-in-place concrete pavement formwork, the equipment includes socket holes 1, movable support rods 2, right-angle positioning plates 3, socket joints 4 and steel back corrugated support strips 5. The main body is made of aluminum alloy material. When using, first fix the right-angle positioning plate 3 to ensure that the formwork is perpendicular to the pouring foundation surface, and then fix the movable support rods 2 on both sides. After fixing one formwork, the socket 1 of the next formwork is connected to the fixed formwork. It can also be connected with the 4 socket connector of the next template, or the socket connector of the next template can be connected with the socket hole of the fixed template.

Fixing the right-angle positioning plate first can ensure that the formwork is perpendicular to the pouring foundation surface, and then the formwork is integrally fixed by the movable support rod. The connection of the socket hole and the socket joint can improve the integrity of the formwork and reduce the construction of the formwork joints. The steel back corrugated support bar ensures the overall strength of the formwork.

When the formwork is used, the right-angle positioning plate is first fixed to ensure that the formwork is perpendicular to the pouring foundation surface, and then the movable support rods on both sides are fixed. After one formwork is fixed, the socket holes of the next formwork are connected with the socket joints of the fixed formwork. Or the socket joint of the next template can be connected to the socket hole of the fixed template. The movable support rod 2 is made of threaded steel brazing and fixed on the base with a nut.

The template is made of aluminum alloy, and the overall shape is basically rectangular. The two ends of the formwork are respectively provided with socket holes and socket joints, two steel back corrugated support bars are set on one side, three-hole right-angle positioning plates are set in the middle, and two horizontal support rods are set every two meters. Fix from the middle to both sides, then insert the next piece of template socket connector into the socket hole of the fixed template, and fix again from the middle to the sides.

After using the new formwork, it can effectively avoid the drawbacks of the traditional channel steel formwork. It can not only speed up the construction of the cast-in-place concrete pavement formwork, but also reduce the construction of the formwork joints, improve the integrity of the formwork, have higher precision, and reduce the number of formwork. The personnel and machinery required for construction are more fluent and beautiful in linear shape and appearance. Thereby, construction problems such as poor appearance after concrete pouring due to the material of the steel formwork and leakage of slurry at the joints are reduced, the construction progress is accelerated, and the cost is reduced at the same time.
