Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to a hole blocking device for the construction of a line hole and a material transfer hole of a cast-in-place floor slab. Background Art
[0002] During the construction of the main structure of a building project, it is necessary to leave a wiring hole and a material transfer port on the floor slab for the main line placement, material transportation or temporary cable laying of the floor, etc., and use concrete to seal it after the entire structure of the building is completed. There are two traditional ways to seal the hole. One is to use the template as a base, pass a wire or a hook through the center and fix it with the help of a cross bar. This method of sealing has a low degree of integration with the floor and has the risk of water seepage, and the exposed wire and hook need to be cut off later. The second is to use the template as a support plate, and use wooden squares or steel pipes under the support plate for support. This method has poor stability and poor adaptability. It is easy to cause leakage due to loose sealing, and there is a risk of leakage due to contact. Therefore, we proposed a hole sealing device for the construction of wiring holes and material transfer ports for cast-in-place floor slabs. Summary of the invention
[0003] In view of the shortcomings of the existing hole sealing devices for the construction of layout holes and material transfer ports of cast-in-place floor slabs, the utility model provides a hole sealing device for the construction of layout holes and material transfer ports of cast-in-place floor slabs, which has the advantages of an upper thin steel plate installed at the upper end of the material transfer port, and a lower thin steel plate arranged at the lower end of the material transfer port. By tightening the first threaded steel bar and rotating the mountain nut at the same time, the mountain nut pushes the mountain clamp to move upward, and then the mountain clamp drives the lower thin steel plate to be clamped and limited at the position of the lower end of the material transfer port, thereby solving the problems raised in the above-mentioned background technology.
[0004] The utility model provides the following technical scheme: a hole plugging device for the construction of a layout hole and a material transfer port of a cast-in-place floor slab, comprising a cast-in-place floor slab, a material transfer port is opened inside the cast-in-place floor slab, positioning grooves are opened on both sides of the upper part of the material transfer port, a circular steel is placed inside the positioning groove, an upper thin steel plate is fixedly connected to the middle part of the circular steel, a sleeve is welded to the lower part of the upper thin steel plate, a first threaded steel bar is connected to the internal thread of the lower end of the sleeve, a fastening nut is fixedly connected to the lower end of the first threaded steel bar, a lower thin steel plate is placed at the lower end of the material transfer port, a second threaded steel bar is threadedly connected to the lower end of the fastening nut, a mountain-shaped card is movably sleeved on the outside of the second threaded steel bar, a mountain-shaped nut is sleeved on the outside of the second threaded steel bar, a spring is fixedly connected to the side of the circular steel, and a gasket is fixedly connected to the other side of the spring.
[0005] Furthermore, the circular steel is made of Q235 steel, has a diameter consistent with the floor slab steel bars, and a length greater than the upper size of the material transfer port.
[0006] Furthermore, the lower thin steel plate is attached to the lower end of the fastening nut, and the second threaded steel bar passes through the lower thin steel plate and is installed inside the fastening nut at the same time.
[0007] Furthermore, the mountain-shaped clamp is arranged at the lower part of the lower thin steel plate, and the mountain-shaped nut is located at the lower end of the mountain-shaped clamp.
[0008] Furthermore, the spring and the gasket are welded to two sides of the circular steel material, and the gasket is fitted inside the positioning groove.
[0009] Furthermore, the upper thin steel plate and the lower thin steel plate are made of steel sections, and their sizes can be customized according to the size of the hole. The size of the upper thin steel plate is about one-fifth of the upper opening of the material transfer port, and the size of the lower thin steel plate is larger than the lower opening of the material transfer port. Beneficial Effects
[0010] 1. The hole plugging device for the construction of the layout hole and the material transfer port of the cast-in-place floor slab uses upper thin steel plates and lower thin steel plates of different sizes according to the different opening sizes of the material transfer port. The upper thin steel plate is installed at the upper end of the material transfer port at the same time, and the round steel is arranged inside the positioning groove. At the same time, the lower thin steel plate is installed at the lower end of the material transfer port. The fastening nut is rotated to ensure that the upper thin steel plate and the lower thin steel plate are fitted at both ends of the material transfer port. At the same time, the mountain nut is rotated to push the mountain clamp to clamp and limit the position of the lower thin steel plate. At this point, the lower thin steel plate can block the lower end of the material transfer port. Then the equipment can be used inside and outside the material transfer ports of different sizes, thereby improving the reuse rate of the equipment, solving the problem of poor plugging effect through effective reinforcement, and reducing the cost of chiseling and repairing in the later stage, thereby reducing the construction cost.
[0011] 2. The hole plugging device for the layout hole and material transfer port of the cast-in-place floor slab is equipped with springs on both sides of the circular steel. The springs push the gasket to move to both sides. At the same time, under the action of elasticity, the upper thin steel plate can be driven to move to the upper end of the material transfer port, thereby improving the accuracy of equipment installation and positioning.
