Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a screw hole blocking device. Background Art

[0002] The most common formwork technology in cast-in-place structure construction in my country's construction industry is the screw-reinforced formwork system, which will leave countless screw holes on the vertical concrete structure. If the screw holes in the locations where waterproofing is required are improperly sealed and cause leakage, this will not only reduce the quality of the project, but also cause unnecessary economic disputes.

[0003] In the prior art, the following methods are generally used to seal the screw hole:

[0004] The first method is to use simple cement mortar for filling. To use this method, you must first clean the wall sleeve and residue in the bolt hole, wet it with water, and then fill the screw hole with cement mortar with expansion agent. However, due to the small diameter of the screw hole and the wall thickness of 200mm to 300mm, filling the mortar requires a high level of professional skills and sense of responsibility of the operator. Therefore, this method is costly, not easy to operate, and the mortar is not easy to fill densely, and the quality is difficult to guarantee.

[0005] The second method is to first seal the outer bolt holes with cement mortar, and then inject foam from the inside. This method first requires cleaning the sleeve and residue in the bolt hole and moistening it with water, and then filling it with waterproof mortar and injecting foam to seal it. However, the defects of this method are: the density of the mortar that first seals the outer end of the bolt hole is difficult to ensure, resulting in a loose combination of the waterproof coating and the mortar that seals the outer end, which is prone to quality risks of wall falling off, and the amount of foam injected is not easy to control; the three processes have a lot of construction content, complex processes, and low work efficiency. The cost of using foam is high and the technical level of workers is required to be high. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a screw hole plugging device, which has low manufacturing cost, is basically made of raw materials on the construction site, is easy to use, improves work efficiency while ensuring construction quality, and is reusable.

[0007] In order to achieve the above object, the technical solution of the utility model is:

[0008] A screw hole sealing device comprises a mortar filling tube and a push rod with one end sleeved in the inner cavity thereof, wherein the end of the push rod located in the mortar filling tube is connected to a push block, the upper surface of the push block is provided with a leak-proof sheet in contact with the inner wall of the mortar filling tube, the other end of the push rod is connected to a handle, and a spring is sleeved on the outer diameter of the push rod.

[0009] The above-mentioned screw hole sealing device, the mortar filling tube includes a handle part and a mortar hopper part; the cross-section of the mortar hopper part is semicircular, and the push block can perform piston motion in the mortar hopper part under the action of the push rod, so as to push the mortar into the screw hole.

[0010] In the above-mentioned screw hole plugging device, the diameter of the push block is smaller than the inner diameter of the mortar hopper.

[0011] In the above-mentioned screw hole plugging device, the spring is arranged in the inner cavity of the handle part, and one end of the push rod passes through the spring and extends into the mortar hopper part.

[0012] The above-mentioned screw hole sealing device has a pressing plate on the push rod, and the pressing plate is located at the end of the handle part away from the mortar hopper part. When the push rod is pushed, the pressing plate can move toward the mortar hopper part with the push rod to compress the spring. When the push rod is released, the pressing plate can be reset under the action of the elastic force.

[0021] The present application adopts a design structure of a mortar filling tube 1, a push rod 2 and a push block 3, which has a simple structure, is basically made of raw materials on the construction site, has a low cost, and is easy to use. When performing the screw hole sealing construction, the mortar is shoveled into the mortar hopper part 11, and the mortar hopper part 11 is placed in the screw hole. The push rod 2 is pushed at a uniform speed, and the mortar can be pushed into the screw hole and tamped through the push block 3. This operation is performed two to three times in succession until the screw hole is completely filled.
