Description

Technical Field

[0001] The utility model belongs to the technical field of water, electricity and heating construction, and in particular relates to a construction device for a reserved hole for water, electricity and heating in a residence. Background Art

[0002] For mechanical and electrical installation, water, electricity and heating pre-embedded is the difficulty and key point of construction. It complements and restricts other processes. Controlling the quality of pre-embedded can not only shorten the construction period and save costs, but also lay a good foundation for the next step of installation. Water, electricity and heating are usually reserved by burying wire boxes, casings, etc. in the wall and ceiling structure in advance, fixed with steel wire, filling sawdust and other debris inside the wire box, and then pouring concrete into the structure to form a cavity between the concrete and the wire box, that is, the reserved hole.

[0003] During the construction process of the water, electricity and heating reserved holes in the prior art, it is necessary to fill the wire box with sawdust to prevent cement from flowing back into the wire box. After the sawdust is filled, it is necessary to seal it with tape. The sawdust and tape can only be used once, which wastes resources. In addition, during the rainy season, water seepage from unfinished pipes or floor slabs will cause the sawdust in the wire box to become wet and soaked in water. During excavation, sawdust mixed with water can easily pour into the mouth, nose or body of construction workers, causing damage to their health. Utility Model Content

[0004] The purpose of the utility model is to provide a construction device for reserved holes for residential water, electricity and heating, which can replace the traditional sawdust tape filling method to fill the inside of the wire box to prevent concrete backflow, and can be used multiple times to avoid waste of resources and protect the health of construction workers. It can drain the water leaking from the inside of the wire box to keep the inside of the wire box dry and prevent water from pouring onto the construction workers during excavation and contaminating their clothes.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A construction device for reserved holes for water, electricity and heating in a residence comprises a wire box and a support block, wherein a screw groove is fixedly connected at the bottom center of the wire box, a rotating rod is rotatably assembled at the center of the support block, a second guide groove is provided at the bottom of the support block in an array, a first guide groove is provided at the four corners of the support block, the first guide groove is fixedly connected to the second guide groove, a screw is fixedly connected to the bottom of the rotating rod, the screw is rotatably screwed to the screw groove, a cover plate is movably covered on the top of the wire box, the rotating rod is rotatably connected to the center of the cover plate, and water permeable holes are provided in an array around the cover plate.

[0007] Sliding bars are fixedly connected to both sides of the inner wall of the wire box.

[0008] Both ends of the top of the wire box are fixedly connected with lock buckles.

[0009] The outer wall of the support block is provided with sliding grooves in an array for the sliding bars and the lock buckles to slide and engage with each other.

[0010] A rotation groove for allowing the rotation rod to rotate is formed through the center of the support block.

[0011] A retaining ring is fixedly connected to the outer wall of the rotating rod and is located below the cover plate.

[0012] The technical effect achieved by the utility model is that it can replace the traditional sawdust tape filling method to fill the inside of the wire box, prevent concrete backflow, and can be used multiple times to avoid waste of resources and protect the health of construction workers. It can drain the water leaking from the inside of the wire box and keep the inside of the wire box dry, preventing water from pouring onto the construction workers during excavation and contaminating their clothes.
