Description

Technical Field

[0001] The present application relates to the field of prefabricated building construction, and in particular to a prefabricated building pipe shaft unit structure and a construction method thereof. Background Art

[0002] In recent years, prefabricated buildings have developed rapidly and accounted for an increasing proportion in new buildings. The advantages it has, such as more reliable quality, energy conservation and environmental protection, shorter construction period, and reduced labor force, have made it shine.

[0003] There is a pipe shaft in the building. The pipe shaft is a vertical shaft in the building for arranging vertical equipment pipelines. For the traditional small pipe shaft, the interior is a rectangle with an area of 0.4 - 0.6 square meters. The space is narrow and the clear height is high. It is difficult for personnel to enter for construction. As a result, a series of problems are likely to occur, such as uneven plastering, non-square internal and external corners, incomplete paint, and non-standard pipe installation, leading to inconvenient construction of the pipe shaft. Summary of the Invention

[0004] In order to facilitate the construction of small pipe shafts, the present application provides a prefabricated building pipe shaft unit structure and a construction method thereof.

[0005] In a first aspect, the present application provides a prefabricated building pipe shaft unit structure, adopting the following technical solution: A prefabricated building pipe shaft unit structure includes a unit box, connecting components, and several pipes. A plurality of pipe openings for accommodating the ends of the pipes are provided at the top and bottom of the unit box. The connecting components are arranged on the top of the unit box, and a plurality of sleeves are embedded on the connecting components. The positions of the sleeves correspond to the pipes, and the sleeves connect the pipes on two unit boxes.

[0006] By adopting the above technical solution, the pipe shaft unit structure pre-buries the pipes on it, and then can be hoisted and placed into the holes reserved in the building. The unit box is directly formed by concrete pouring, and the surface can reach the level of fair-faced concrete, without the need for plastering, puttying, or painting on the inner wall. All construction is completed in the factory, so that subsequent assembly and installation can be directly carried out, and the construction time is greatly shortened.

[0007] Optionally, the unit box includes a box body and a cover plate. An opening is provided on one horizontal side of the box body, and the cover plate closes the opening.

[0008] By adopting the above technical solution, it is convenient to install components and perform maintenance inside the box, and sundries can also be placed inside the box.

[0009] Optionally, a floor drain and a connecting pipe are embedded at the top of the connecting components. One end of the connecting pipe is connected to the floor drain, and the other end is connected to the sleeve.

[0010] By adopting the above technical solution, the floor drain enables the accumulated water between floors to be discharged from the pipe and is not easily introduced into the unit box, so that the unit box is not easily accumulated with water.

[0011] Optionally, the several pipes include a drain pipe, a wastewater pipe, a vent pipe, a sewage pipe and a rainwater pipe.

[0012] By adopting the above technical solution, it is convenient to meet the various requirements of drainage and exhaust on the floors.

[0013] Optionally, a spare pipe is provided on the side wall of the unit box.

[0014] By adopting the above technical solution, it is convenient to connect other pipe fittings for use later and facilitate subsequent installation.

[0015] Optionally, the cross-sectional area of the unit box in the horizontal direction is 0.4 - 0.6 square meters.

[0016] By adopting the above technical solution, the cross-sectional area of the pipe well unit structure is small, which is convenient for hoisting construction, and the production saves materials and reduces the occupied available area in the building.

[0017] In the second aspect, the present application provides a construction method for a building prefabricated pipe well unit structure, adopting the following technical solution: A construction method for the above-mentioned building prefabricated pipe well unit structure includes the following steps: S1, prefabrication of several pipe well unit structures: Pour concrete into the formwork, demold after curing and assemble into a unit box, install connecting components on the top of the unit box, leave several pipe openings on the unit box, install pipes in the pipe openings and fix them; install and fix sleeves on the connecting components, and fix the top ends of the pipes with the sleeves; S2, embedding welding steel plates: Reserve a cavity for accommodating the unit box on each floor, pour a concrete connecting platform inside the cavity, bury welding steel plates inside the connecting platform, and expose the side of the welding steel plate facing the inside of the cavity; S3, installation: Lift the pipe well unit structure and lower it from the top of the building to the bottom floor ground inside the cavity. The top of the pipe well unit structure is located at the welding steel plate. Place support steel plates circumferentially on the top of the pipe well unit structure. Weld and fix the end of the support steel plate close to the welding steel plate with the welding steel plate; then lift another pipe well unit structure and place it above the support steel plate. Connect the sleeves at the bottom of the pipe well unit structure to the bottom ends of several pipes of the upper pipe well unit structure to make the pipes of the two pipe well unit structures communicate with each other; repeat the steps of welding the support steel plates and hoisting the pipe well unit structures to complete the installation; S4, filling the gaps, fill the gaps between the floor and the pipe well unit structure.

[0018] By adopting the above technical solution, the unit is installed into the building by hoisting, which makes the construction efficiency high. At the same time, the unit box is solidified by plain concrete, with a long service life. The surface of the unit box does not need to be painted, puttyed or painted, so there is no need to enter the unit box manually, simplifying the construction. The top of the pipeline well unit structure is pre-embedded with hanging steel, which is removed after the hoisting is completed, which is convenient for operation. The welded steel plate is fixed to the floor. After the support steel plate is welded, it has a supporting effect on the pipeline well unit structure, dispersing the force on each floor to make the support stable.

[0019] Optionally, the supporting steel plate is an L-shaped angle steel, one side of the supporting steel plate is placed on the top surface of the pipeline well unit structure, and the other side is attached to and welded to the welding steel plate.

[0020] By adopting the above technical solution, the upper surface of the L-shaped angle steel and the surface of the supporting steel plate are welded, so that the welding points are increased, the two surfaces are fixed for support, the welding firmness is improved, and the supporting strength is improved at the same time.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. The pipeline well unit structure pre-buries the pipeline, and then can be hoisted into the reserved cavity of the building. The unit box is directly formed by concrete pouring, and the surface can reach the level of plain concrete. There is no need to paint, putty or paint the inner wall. All construction is completed in the factory, so that subsequent assembly and installation can be carried out directly, and the construction time is greatly shortened; 2. The floor drain is set up so that the accumulated water between floors can be easily discharged from the pipe; 3. The welded steel plate is fixed to the floor. After welding, the supporting steel plate has a supporting effect on the pipeline well unit structure, dispersing the gravity on each floor to make the support stable.
