Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a temporary vertical water supply method for a high-rise building. Background Art

[0002] Vertical water supply for floor construction has always been a difficult problem in project implementation, requiring timely and convenient installation and disassembly of vertical water supply, no impact on formal engineering construction, and as little finishing work as possible after disassembly. The traditional method of laying temporary water supply pipelines for high-rise or multi-story buildings is to install them along the outer wall or along the pipeline well to the roof, and use a variable frequency water pump for water supply. Although the above-mentioned traditional water supply method can solve the problem of temporary water supply on the upper floors of high-rise buildings, it will affect the construction effect inside the outer wall of the building and the decorative effect of the pipeline well. At the same time, it will also have an adverse effect on the use of the outer wall and the pipeline well, and occupy the building space. It is often displaced during the construction process. The water pipe layout requires a large number of brackets, and the installation, removal and repair are very troublesome. In winter, the water pipes need to be insulated and antifreeze treated, which consumes a lot of manpower and material resources, greatly increasing the construction cost. In order to solve the above technical problems, the present invention designs a new type of temporary vertical water supply method for high-rise buildings. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a temporary vertical water supply method for high-rise buildings. During the construction of the vertical reinforcement of the structure, the vertical water supply pipe is pre-buried. After the mold is removed, the internal pipe head of the structure is cleaned out and the external water outlet is prepared, so that normal water use can be achieved, which is convenient and quick.

[0004] The present invention achieves the above technical objectives through the following technical means.

[0005] A temporary vertical water supply method for a high-rise building includes the following steps: Step 1: Construction water design; Step 2: Assemble and install the pre-buried water pipes on the first floor; Step 3: The first floor concrete structure is sealed and poured. After the concrete pouring is completed and meets the requirements, the formwork is removed; Step 4: Clean the pre-buried water pipe head on the first floor, then connect the water inlet valve to the water source; Step 5: Assemble the pre-buried water pipes in the middle section; Step 6: Connect the upper and lower pre-buried water pipes; Step 7: The upper concrete structure is sealed and poured. After the concrete pouring is completed and meets the requirements, the formwork is removed; Step 8: Install the faucet; Step 9: Repeat steps 5 to 8, and construct the remaining layers of pre-buried water pipes upwards in sequence.

[0006] Furthermore, in step 2, the pre-buried water pipes on the first floor are pre-buried and installed together with the vertical steel bars of the concrete structure on the first floor, and are pre-buried and fixed by the vertical steel bars, and the upper part of the pre-buried water pipes on the first floor extends into the upper floor.

[0007] Furthermore, the pre-buried water pipes on the first floor include galvanized steel pipes connected by threads, end valves and end elbows are installed on the upper ends of the galvanized steel pipes, water pipe elbows are installed on the lower ends of the galvanized steel pipes, the mouths of the water pipe elbows are tightly sealed with water pipe plugs, and the water pipe elbows are used in conjunction with the "86" junction box for pre-buried, and before the template is installed, the "86" junction box is filled tightly with soft materials and sealed with tape, and the box mouth is close to the template.

[0008] Furthermore, in step 5, the embedded water pipe in the middle section includes a galvanized steel pipe connected by a thread, an end valve and an end elbow are installed at the upper end of the galvanized steel pipe, a water pipe tee is installed at the lower end of the galvanized steel pipe, the opening of the water pipe tee is tightly sealed with a water pipe plug, and the water pipe tee is used in conjunction with an "86" junction box for pre-embedded use, and before the upper template is installed, the "86" junction box is tightly filled with soft material and sealed with tape, and the box opening is close to the template.

[0009] Furthermore, the specific process of step 6 is as follows: Before installing the upper formwork, close the water inlet valve on the first floor, remove the end valve on the upper part of the pre-buried water pipe on the first floor, insert the top of the galvanized steel pipe of the pre-buried water pipe on the first floor into the "86" junction box of the middle section pre-buried water pipe and connect it to the water pipe tee, then carry out the pre-buried installation of the middle section pre-buried water pipe and ensure that the upper part of the middle section pre-buried water pipe extends into the upper layer.

[0010] Furthermore, the specific process of step 8 is as follows: Clean the filling material in the "86" junction box of the middle section pre-buried water pipe, close the bottom water inlet valve, remove the water pipe plug at the three-way opening of the middle section pre-buried water pipe, connect the short pipe and faucet, and then open the bottom water inlet valve to supply water upwards.

[0011] Furthermore, when water is not needed in the later stage of interior decoration of the building, the external short pipes on each floor are manually removed, grouting is performed in the water supply pipeline, and the decorative surface is partially repaired after the mortar is filled in the "86" junction box.

[0012] The present invention has the following beneficial effects: The present invention directly pre-buries and installs construction water pipelines in structural columns and walls, so that temporary water supply pipelines and structures are implemented synchronously, reducing the support for temporary water supply construction and the subsequent removal and repair work. It can ensure timely supply of water for concrete maintenance, facilitate the cleaning of the working surface, and provide water for fire prevention on the working surface.

[0013] The present invention is constructed once and can be used throughout the entire construction cycle; construction water is directly supplied to the working surface and workers can use it at any time, which improves the convenience of concrete maintenance; overcomes the anti-freezing problem of water pipes in winter; solves the problem of temporary water pipes occupying building space and often shifting during construction; the construction water can be used to directly flush the working surface and can replace compressed air for sawdust cleaning; water can be sprinkled on the hot work points on the working surface to prevent fire; and the heat-prevention and cooling effect for workers in high temperature seasons is obvious.

Figure 5 shown.

[0017] Step 3: Seal the formwork of the first-floor concrete structure columns (walls), and then pour the first-floor concrete structure columns (walls). After the concrete pouring is completed and reaches the strength requirement, remove the formwork 7.

[0018] Step 4: Figure 6 As shown, clean the pre-buried water pipe head, then connect the external water inlet valve 9, connect the water source, open the corresponding valve to send water upward, and the concrete can be used for curing.

[0019] Step 5: Assemble the pre-buried water pipes in the middle section; like Figure 2 As shown, the embedded water pipe in the middle section includes a galvanized steel pipe 1 connected by a thread, an end valve 2 and an end elbow 3 are installed on the upper end of the galvanized steel pipe 1, a water pipe tee 10 is installed on the lower end of the galvanized steel pipe 1, the mouth of the water pipe tee 10 is tightly sealed with a water pipe plug 5, and the water pipe tee 10 is used in conjunction with an "86" junction box 6 for pre-embedded use, and before the upper column formwork is installed, the "86" junction box 6 is tightly filled with soft material and sealed with tape, and the box mouth is required to be close to the template 7.
