Description

Technical Field

[0001] This utility model belongs to the field of building construction, specifically relating to a new type of concrete sealing tool for structural columns. Background Technology

[0002] During the concrete pouring process for structural columns, the traditional method of using a trumpet-shaped wooden mold to seal the top of the structural column can easily result in an unsightly finished product. Furthermore, the excess concrete left at the top seal leads to material waste. The excess concrete also needs to be removed and trimmed later, increasing labor input and thus increasing costs. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a new type of concrete sealing tool for structural columns. This tool can not only reduce the waste of concrete materials and save labor input, but also improve the forming effect of structural columns and effectively reduce costs.

[0004] The technical solution adopted by this utility model to solve this technical problem is: a novel concrete sealing tool for structural columns, comprising a U-shaped base plate, a flared opening, and a sealing device. The U-shaped base plate is a large square steel plate with a small square steel plate cut off, and four screw holes are drilled on the plate for fixing the base plate to the structural column. The flared opening consists of two right-angled triangular side plates and a rectangular retaining strip, fixed at the opening of the U-shaped base plate. Each of the two triangular side plates has a hole for fixing a pin. The sealing device consists of a rectangular steel plate, two pins, and a handle. One side is connected to the U-shaped base plate by a hinge, and the other side can be opened to flip the concrete for unloading and closed to seal the opening.

[0005] Furthermore, the "U"-shaped base plate is made of 3mm thick steel plate, with the large square steel plate measuring 350*350mm and the smaller square steel plate cut off measuring 250mm*250mm. The base plate is fixed to the structural column with screws.

[0006] Furthermore, the flared mouth is made of 3mm thick steel plate. The triangular steel plate is 250*200*320mm in size, and the rectangular baffle is 250*40mm in size. One side of each of the two triangular steel plates is welded to the steel plate baffle, and the other side is welded to the "U"-shaped base plate.

[0007] Furthermore, the rectangular steel plate of the sealing device is made of stainless steel, with dimensions of 500*247*3mm. The pin is a medium-sized stainless steel hinged pin, which is welded to the rectangular steel plate. The hinge is 4 inches long, and the handle is 120mm long and is welded to the rectangular steel plate.

[0008] The beneficial effects of this utility model are that it solves the problem of material and labor waste in the construction process of structural columns. The materials are readily available, the cost is low, the manufacturing process is simple, the structure is reliable, and it can be reused repeatedly, making it easy to promote in the construction field and effectively reducing costs while improving the quality of the structure.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. See also Figures 1 to 3 As shown, a novel concrete sealing tool for structural columns includes a U-shaped base plate 1, a flared opening, and a sealing device. The U-shaped base plate 1 is the shape left after cutting a small square steel plate from a large square steel plate, with four screw holes 8 drilled on the base plate. The flared opening is formed by welding two right-angled triangular side plates 4 and a rectangular steel strip 2, and is welded and fixed to the opening of the U-shaped base plate 1. Each triangular side plate has a hole for fixing a pin 5. The sealing device consists of a rectangular steel plate 3, two pins 5, and a handle 7. One side is connected to the U-shaped base plate 1 by a hinge 6, and the other side can be opened to flip the concrete for unloading and closed to seal the opening.

[0014] Align the screw holes 8 in the U-shaped base plate with the corresponding positions of the structural column template, and fix the closing tool with screws. Hold the handle 7 with one hand and open the two pins 5 with the other hand. Flip the rectangular steel plate 3 onto the flared steel retaining strip 2 and pour the structural column concrete. After the concrete is poured and vibrated, flip the rectangular steel plate 3 to the vertical position and immediately tighten the pins 5 to seal the concrete and carry out subsequent curing.

[0015] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the prototype of this utility model should also be considered within the protection scope of this utility model.
