Description

Technical Field

[0001] The utility model relates to the technical field of concrete casting formwork, in particular to a channel bottom plate casting side formwork. Background Art

[0002] The channel floor is an important part of the channel structure in water conservancy projects and is located at the bottom of the channel. Its main function is to support the water flow and guide it to flow in a predetermined direction, while preventing the water flow from eroding the soil and ensuring the stability of the channel and the water delivery efficiency.

[0003] In the design and construction of channels, the bottom plate is usually cast with concrete, and wooden formwork is used as the casting formwork. The advantage of wooden formwork is that it is inexpensive and can be processed into special or curved shapes to fit the curved part of the bottom of the channel. However, the construction and disassembly of wooden formwork are relatively troublesome, and the reuse rate is low. It is very easy to be damaged after being disassembled and used several times in the casting construction of the channel bottom plate. It is not suitable for long straight or low-curvature channel bottom plates, which is time-consuming and labor-intensive, and reduces the casting construction efficiency of the channel bottom plate.

[0004] To this end, the present application specifically proposes a channel floor casting side form to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of the utility model is to solve the above-mentioned deficiencies and provide a channel bottom plate casting side formwork, which is easy to disassemble and assemble and can be recycled, thereby improving the casting construction efficiency.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A channel bottom slab casting side formwork comprises: a channel steel, one of the side plates of which is evenly arranged with a plurality of positioning pins; a plurality of supporting positioning members evenly arranged and fixedly arranged in a groove of the channel steel, for effectively supporting and positioning the channel steel when it is placed on its side; and a plurality of clamping members evenly arranged and fixedly arranged on the other side plate of the channel steel, for clamping a waterproof membrane.

[0008] Furthermore, the supporting positioning member includes a triangular steel bar fixedly arranged in the groove of the channel steel, a ring fixedly arranged at one end of the triangular steel bar extending out of the groove of the channel steel, and an anchor rod movably inserted in the ring, and the triangular steel bar is parallel to the end face of the channel steel.

[0009] Furthermore, the anchor rod comprises a vertical steel bar movably inserted in the sleeve and a transverse steel bar fixedly arranged on the top of the vertical steel bar and perpendicular thereto.

[0010] Furthermore, the clamping member includes a U-shaped block fixedly arranged on another side plate of the channel steel, a screw threadedly connected and passing through one side of the U-shaped block, a handwheel fixedly arranged on one end of the screw extending out of the U-shaped block, and a top block rotatably arranged on the other end of the screw.

[0011] Furthermore, a latch is fixedly provided at one end of the channel steel bottom plate, and a socket which is plug-matched with the latch is fixedly provided at the other end of the channel steel bottom plate.

[0012] The beneficial effects of the utility model are embodied in:

[0013] 1. The utility model arranges positioning pins on one of the side plates of the channel steel, arranges a clamping piece on the other side plate, and arranges a positioning support piece in the groove of the channel steel, so that two rows of channel steels are placed sideways with their bottom surfaces facing each other, and the positioning pins and the positioning support piece are used to position and fix the channel steels. At this time, the opposite surfaces of the two rows of channel steels can be used as casting side templates for the channel bottom plate. The waterproof membrane laid on the bottom surface of the channel steel is compressed by arranging the clamping piece to avoid direct contact between the concrete slurry and the channel steel, thereby preventing corrosion of the channel steel and inconvenience in demoulding. At the same time, it also prevents the concrete slurry from seeping out from the joints of adjacent channel steels. Compared with wooden molds, it has the advantage of higher recycling rate.
