[0020] The following will describe the present utility model in detail with reference to the accompanying drawings.

[0021] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, a fastening device for a concrete counter-camber formwork is provided, which includes a first clamping member 1 and a second clamping member 2. Connecting blocks are provided on the sides of the first clamping member 1 and the second clamping member 2 away from the formwork 8, and anchor bolts 6 for connecting concrete members are installed on the connecting blocks. The first clamping member 1 and the second clamping member 2 are arranged in parallel and connected by a connecting member 3. Clamping rods 4 for clamping the formwork 8 are installed on the sides of the first clamping member 1 and the second clamping member 2 close to the formwork 8. The clamping rods 4 are parallel to the first clamping member 1 or the second clamping member 2 on the same side. The concrete member is generally a floor.

[0022] In this embodiment, refer to Figure 1 and Figure 2 The connecting member 3 is an adjusting screw rod. The adjusting screw rod is connected to the first clamping member 1 and the second clamping member 2 and locked with nuts. The adjusting screw rod is provided to adjust the gap between the first clamping member 1 and the second clamping member 2 according to the pouring thickness requirement of the concrete counter-camber 7, so as to better meet the construction requirements of concrete counter-cambers 7 with different thickness dimensions.

[0023] In this embodiment, the formwork 8 is an aluminum alloy formwork. The formwork 8 is used to assist in the pouring and forming of the concrete counter-camber. The surface of the aluminum alloy formwork is relatively flat and smooth, which is beneficial to the relatively flat and smooth surface of the concrete counter-camber after pouring and forming. Of course, on the premise of meeting the requirement of assisting in the pouring and forming of the concrete counter-camber 7, the formwork 8 can also be a wooden formwork or a plastic formwork.

[0024] In this embodiment, a slot adapted to the clamping rod 4 is provided on one side of the formwork 8, so that the surface of the concrete counter-camber is as flat as possible after pouring and forming, and there is no depression on the surface.

[0025] In this embodiment, refer to Figure 1 Both the first clamping member 1 and the second clamping member 2 are of a hollow column structure. The hollow structure can reduce the weight of the first clamping member 1 and the second clamping member 2.

[0026] In this embodiment, the clamping rod 4 is a metal rod, and the metal material can ensure that the clamping rod 4 has sufficient strength. Preferably, the clamping rod 4 is an aluminum rod, and the shape of the clamping rod 4 includes but is not limited to a cylindrical shape or a cuboid shape.

[0027] In this embodiment, refer to Figure 1 and Figure 3 , the upper end of the clamping rod 4 is connected to the clamping rod mounting seat, and the clamping rod mounting seat is installed on the first clamping member 1 and the second clamping member 2 through the adjustable screw rod 5 and the nut, which is convenient for adjusting the distance between the clamping rod 4 and the corresponding first clamping member 1 or the second clamping member 2, so as to clamp templates 8 with different thickness dimensions.

[0028] Working process of the present utility model:

[0029] During the working process of the fastening device for the concrete counterfort formwork, in rooms with waterproof requirements such as bathrooms and kitchens, a cast-in-place concrete counterfort platform needs to be made at the bottom of the remaining walls except for the door opening positions as required. Clean the base, position and set out the lines, pre-embed or post-embed the tie bars. Place the formwork at the preset pouring position. The first clamping member 1 and the second clamping member 2 are fixed on the floor through the anchor bolts 6. The first clamping member 1 and the second clamping member 2 are tightly connected by the connecting members. The formwork 8 is clamped and fixed by the clamping rod 4. According to the design requirements, a plain concrete counterfort with a height of 200 mm and strength grade C25 is cast at the bottom of the walls of kitchens, bathrooms, water and electricity pipe wells, equipment platforms and between two formworks 8. To ensure that the formwork does not shift during the pouring of the concrete counterfort, multiple fastening devices can be arranged at intervals to fix the formwork.

[0030] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any scheme obtained by simply transforming the present utility model falls within the protection scope of the present utility model.
