Referring to Figures 1-2, a device for reinforcing the formwork of a plain concrete slab is shown, which includes a U-shaped limit frame 1, an outer form baffle plate 2, an inner form baffle plate 3, a telescopic member 4, a telescopic member 5, a pressure plate 6 and a pressure plate 7. The outer form baffle plate 2 and the telescopic member 4 are respectively arranged at the two ends of the U-shaped limit frame 1, the outer form baffle plate 2 is located on the inner side of the U-shaped limit frame 1, the telescopic member 4 is movably inserted into the U-shaped limit frame 1, the pressure plate 6 is arranged at the end of the telescopic member 4 close to the outer form baffle plate 2, the inner form baffle plate 3 is arranged between the pressure plate 6 and the outer form baffle plate 2, and the telescopic member 2 5 is arranged on the inner form baffle plate 3, and a pressure plate 2 7 is provided at the end thereof facing the telescopic member 4.

The reinforcement device is suitable for construction plans with auxiliary walls near the casting area of the fair-faced concrete slab. For example, when casting the fair-faced concrete slab on the outside of the window sill, the pressure plate 1 6 and the pressure plate 2 7 are respectively pressed against the two sides of the auxiliary wall 13, and the inner form baffle plate 3 and the outer form baffle plate 2 are respectively pressed against the casting formwork of the fair-faced concrete slab, so as to replace the traditional perforated reinforcement method, avoid affecting the surface flatness of the cast fair-faced concrete slab, reduce the later repair process and cost, and improve the construction progress and quality.

In order to improve the strength of the outer mold baffle 2 and the inner mold baffle 3, this embodiment is provided with a reinforcement frame 8 on the sides of the outer mold baffle 2 and the inner mold baffle 3 that are away from each other. The reinforcement frame 8 includes a plurality of horizontal and vertical crossed steel pipes. When manufacturing this device, one end arm of the U-shaped limit frame 1 is welded and fixed to the reinforcement frame 8 on the outer mold baffle 2, and the telescopic member 2 5 is connected to the reinforcement frame 8 on the inner mold baffle 3.

The telescopic member 4 includes a threaded rod 4-1 penetrating an end arm of the U-shaped limit frame 1, and a limit nut 4-2 sleeved on the threaded rod 4-1, and the limit nut 4-2 abuts against the U-shaped limit frame 1. When configuring, the limit nut 4-2 can be set only on the inner side of the U-shaped limit frame 1, or two sets of limit nuts 4-2 can be used to clamp and fix the end arm of the U-shaped limit frame 1.

The telescopic member 2 5 includes an internal threaded sleeve 5-1 and a threaded rod 2 5-2, wherein the threaded rod 2 5-2 is inserted into the internal threaded sleeve 5-1, one of which is connected to the pressure plate 2 7, and the other is connected to the reinforcement frame 8 on the inner mold baffle 3. For easy installation and removal, a U-shaped bracket 9 is provided at the end of the telescopic member 2 5 close to the reinforcement frame 8, and the U-shaped bracket 9 is clamped on the reinforcement frame 8.

When the U-shaped support 9 is clamped on the reinforcement frame 8, the part connecting the telescopic member 2 5 and the U-shaped support 9 cannot rotate. Therefore, in order to facilitate adjustment, a rotating handle 10 can be set on the outer wall of the part of the telescopic member 2 5 that is not directly connected to the U-shaped support 9. As described above, the rotating handle 10 can be set on the internal threaded sleeve 5-1 or on the outer wall of the threaded rod 2 5-2.

Elevation plate 1 11 and elevation plate 2 12 can be used to level the auxiliary wall 13 with the top of the outer form baffle 2 and the inner form baffle 3 to ensure the verticality of the outer form baffle 2 and the inner form baffle 3 to prevent the casting formwork of the plain concrete slab clamped by it from being skewed and affecting the construction quality.

The method for construction using the above-mentioned fair-faced concrete slab formwork reinforcement device comprises the following steps:

Place the inner form baffle 3 between the auxiliary wall 13 and the inner formwork of the plain concrete slab, set up a U-shaped limit frame 1 on the inner form baffle 3, and place the outer form baffle 2 on the outer side of the outer formwork of the plain concrete slab; set up the elevation plate 11 on the top surface of the auxiliary wall 13, and use the assistance of an external level gauge to adjust the elevation plate 11 and the elevation plate 2 12 to be level to ensure that the outer form baffle 2 and the inner form baffle 3 are vertical, and at the same time translate the U-shaped limit frame 1 until the outer form baffle 2 is pressed against the outer formwork of the plain concrete slab; adjust the telescopic member 2 5 so that the baffle 2 is pressed against one side of the auxiliary wall 13, and the inner form baffle 3 is pressed against the inner formwork of the plain concrete slab; adjust the telescopic member 1 4 so that the baffle 1 is pressed against the other side of the auxiliary wall 13.

Compared with the prior art, the beneficial effect of the present invention is that in the casting construction of the fair-faced concrete slab with the auxiliary wall 13, the pressure plate 1 6 and the pressure plate 2 7 are respectively pressed against the two sides of the auxiliary wall 13, while the inner form baffle plate 3 and the outer form baffle plate 2 are respectively pressed against the casting formwork of the fair-faced concrete slab, so as to replace the traditional perforated reinforcement method, avoid affecting the surface flatness of the cast fair-faced concrete slab, reduce the later repair process and cost, and improve the construction progress and quality.

The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
