Description

Technical Field

[0001] This invention relates to the field of fluid pipeline layout methods, and more specifically to a method for arranging fluid pipelines within a cavity floor slab. Background Technology

[0002] The existing cavity floor slabs have insufficient internal cavity utilization. The cavity layer has a large volume, but it is only used as a horizontal load-bearing component, leaving a large amount of space idle. The fire protection pipelines in the buildings are relatively complex, which will occupy a lot of space, reduce the utilization rate of the buildings, affect the aesthetics, and the exposed pipelines are more prone to corrosion.

[0003] To address the aforementioned issues, the relevant pipes are now typically placed directly within the cavity floor slab. This improves the utilization of the internal space of the cavity floor slab and reduces the amount of exposed piping. However, this method also has some drawbacks. When using this method, the pipes are mainly concealed, which improves aesthetics but also presents a maintenance challenge. Furthermore, the pipes require angle adjustments during installation, but existing pipes mostly use bends or flexible hoses for angle adjustment. Using bends requires a large number of elbows and is very inconvenient to install, while using flexible hoses requires consideration of fixing issues, which are not convenient. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide a method for arranging fluid pipes built into a cavity floor slab.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a method for arranging fluid pipes built into a cavity floor slab, comprising the following steps:

[0007] (1) Several sets of fluid pipes are arranged in the cavity floor slab. Each set of fluid pipes includes two parallel fluid pipes A and B. The fluid pipes A and B are connected by an intermediate pipe C to form a Z-shaped fluid pipe.

[0008] (2) Reserve a space A on the side of fluid pipe A corresponding to fluid pipe B for repairing fluid pipe B’s axial movement, and reserve a space B on the side of fluid pipe B corresponding to fluid pipe A for repairing fluid pipe A’s axial movement.

[0009] (3) A repair hole is made at the position corresponding to the middle pipe C at the bottom of the cavity floor slab.

[0010] Preferably, a cuboid cavity corresponding to fluid pipe A and fluid pipe B is formed inside the cavity floor, and a plurality of ribs for fixing fluid pipe A and fluid pipe B are formed inside the cuboid cavity.

[0011] Preferably, the cavity floor slab has a plurality of cylindrical cavities corresponding to fluid pipes A and B for fixing fluid pipes A and B, and the reserved spaces A and B are arranged as cylindrical cavities corresponding to fluid pipes A and B.

[0012] Preferably, the intermediate pipe C is a rigid pipe or a flexible hose.

[0013] Preferably, a cover plate is provided at the repair hole.

[0014] Preferably, the intermediate pipe C is fixed to the upper wall of the cavity floor slab by a pipe clamp.

[0015] Preferably, fluid pipe A and fluid pipe B are bendable and expandable pipes.

[0016] Preferably, the fluid pipe A and fluid pipe B include a large-diameter pipe A and a large-diameter pipe B respectively. One end of the large-diameter pipe A and the large-diameter pipe B is a straight pipe section, and the other end corresponding to the straight pipe section is an arc-shaped pipe section. The arc-shaped pipe section of the large-diameter pipe A extends into the arc-shaped pipe section of the large-diameter pipe B. The arc-shaped pipe section of the large-diameter pipe B has a hinge cylinder corresponding to the large-diameter pipe A. The arc-shaped pipe section of the large-diameter pipe A can rotate around the hinge cylinder along the inner wall of the arc-shaped pipe section of the large-diameter pipe B. The straight pipe section of the large-diameter pipe B is internally connected to a small-diameter pipe B that can extend and retract along the inner wall of the large-diameter pipe B. The straight pipe section of the large-diameter pipe A is internally connected to a small-diameter pipe A that can extend and retract along the inner wall of the large-diameter pipe A.

[0017] Preferably, the large-diameter pipe A can be rotated to form an angle of 30-180 degrees with the large-diameter pipe B.

[0018] Preferably, sealing elements are formed between the arc-shaped pipe section of the large-diameter pipe A and the inner wall of the large-diameter pipe B, between the small-diameter pipe A and the large-diameter pipe A, and between the small-diameter pipe B and the large-diameter pipe B. A threaded slide rod is formed on the large-diameter pipe A, and a sliding groove plate is formed on the small-diameter pipe A. The sliding groove plate is provided with a sliding groove corresponding to the threaded slide rod and parallel to the large-diameter pipe A. A threaded slide rod is formed on the large-diameter pipe B, and a sliding groove plate is formed on the small-diameter pipe B.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 13c As shown, this embodiment provides a method for arranging fluid pipes built into a cavity floor slab, including the following steps:

[0042] (1) Several sets of fluid pipes are arranged in the cavity floor slab. Each set of fluid pipes includes two parallel fluid pipes A and B. The fluid pipes A and B are connected by an intermediate pipe C to form a Z-shaped fluid pipe.

[0043] (2) Reserve a space A on the side of fluid pipe A corresponding to fluid pipe B for repairing fluid pipe B’s axial movement, and reserve a space B on the side of fluid pipe B corresponding to fluid pipe A for repairing fluid pipe A’s axial movement.

[0044] (3) A repair hole is made at the position corresponding to the middle pipe C at the bottom of the cavity floor slab.

[0045] like Figure 1 , 2 As shown, in this embodiment, fixing holes are made at the ribs through which the pipes need to pass within the cavity floor slab to secure the fluid pipes. Figure 2 This is a schematic diagram showing the state before the repair hole is opened; the pipe passes through the fixing hole of the rib and is arranged inside the cavity, as shown in the reference diagram. Figure 3 Fluid pipes A and B are arranged in the middle of the cavity and are connected by an intermediate pipe C to form a Z-shaped fluid pipeline. In this embodiment, the intermediate pipe C is fixed to fluid pipes A and B by a threaded connection or other detachable connection methods known to those skilled in the art. The axes of fluid pipes A and B are arranged parallel, and space is reserved for axial movement of the pipes within the cavity. The dotted line in the figure shows the direction of pipe movement. As shown in Figure 4, a repair hole, known to those skilled in the art, is provided at the bottom of the cavity corresponding to the intermediate pipe C. During pipe maintenance, the connection between the intermediate pipe C and fluid pipes A and B is disconnected, and fluid pipes A and B are axially moved within the reserved space in the cavity to expose each part of the pipe to the bottom opening of the cavity for maintenance. In this embodiment, after removing the intermediate pipe C during repair, fluid pipes A and B are kept in a movable state.

[0046] Preferably, in this embodiment, a cover plate, which is well known to those skilled in the art, is provided at the repair hole. In this embodiment, the cover plate is detachably fixed to the cavity floor slab with screws.

[0047] Preferably, in this embodiment, during construction, tee or cross connectors can be installed at pipe joints, such as... Figure 12 As shown, a pipeline network is constructed to achieve series, parallel, and combined series-parallel connections between pipes. An air pump is connected externally to the pipeline network to introduce fluid materials. Existing devices familiar to those skilled in the art are installed at the outlets of relevant branch pipes to achieve specific functions, such as... Figure 1 As shown, the connecting pipes in this embodiment are connected by threaded connections known to those skilled in the art or by other detachable connection methods known to those skilled in the art.

[0048] In this embodiment, fluid pipes A and B are built-in fluid pipes for cavity floor systems that are flexible in placement, easy to maintain and replace, and cause minimal damage to the floor slab. Figure 5As shown, fluid pipes A and B include correspondingly arranged large-diameter pipe A2 and large-diameter pipe B1. One end of each large-diameter pipe A2 and large-diameter pipe B1 is a straight pipe section, and the other end corresponding to the straight pipe section is an arc-shaped pipe section. The arc-shaped pipe section of large-diameter pipe A2 extends into the arc-shaped pipe section of large-diameter pipe B1. The arc-shaped pipe section of large-diameter pipe B1 has a hinge cylinder 5 corresponding to that of large-diameter pipe A2 at its end. The arc-shaped pipe section of large-diameter pipe A2 can rotate around the hinge cylinder 5 along the large-diameter pipe B1. The inner wall of the arc-shaped pipe section of pipe 1 rotates. The straight pipe section end of the large-diameter pipe B 1 is connected to a small-diameter pipe B 3 that can extend and retract along the inner wall of the large-diameter pipe B 1. The straight pipe section end of the large-diameter pipe A 2 is connected to a small-diameter pipe A 4 that can extend and retract along the inner wall of the large-diameter pipe A 2. The axes of the two arc-shaped pipe sections coincide with each other. The above structural features ensure that the arc-shaped pipe with a relatively small diameter can move along the axis inside the arc-shaped pipe with a relatively large diameter. The hinge cylinder 5 acts as a pivot to realize the multi-angle bending of the entire pipe.

[0049] Preferably, in this embodiment, the large-diameter pipe A can rotate to form an angle of 30 degrees to 180 degrees with the large-diameter pipe B. The maximum and minimum angles are illustrated below. Figure 8 As shown.

[0050] like Figure 5-10 As shown, sealing elements are formed between the arc-shaped pipe section of the large-diameter pipe A 2 and the inner wall of the large-diameter pipe B 1, between the small-diameter pipe A 4 and the large-diameter pipe A 2, and between the small-diameter pipe B 3 and the large-diameter pipe B 1. A threaded slide bar 201 is formed on the large-diameter pipe A 2, and a sliding groove plate 401 is formed on the small-diameter pipe A 4. The sliding groove plate 401 has a sliding groove 402 corresponding to the threaded slide bar 201 and parallel to the large-diameter pipe A 2. A threaded slide bar 101 is formed on the large-diameter pipe B 1, and the small-diameter pipe B 1... 3. A second sliding plate 301 is formed on the sliding plate 301. The second sliding plate 301 is provided with a second sliding groove 302 corresponding to the second threaded sliding rod 101 and parallel to the large diameter pipe B 1. The small diameter pipe A 4 and the small diameter pipe B 3 are formed with hexagonal prism outer edges. The hexagonal prism outer edges are convenient for clamping and are beneficial for maintenance. Locking nuts are installed on the first threaded sliding rod 201 and the second threaded sliding rod 101 respectively. The first sliding plate 401 and the second sliding plate 301 adopt a cantilever structure. After extension and retraction, the pipe length is adjusted by fixing it with locking nuts.

[0051] In this embodiment, the hollow floor slab, rib beams, repair holes, cover plates, large-diameter B pipe 1, threaded slide bar 2 101, large-diameter A pipe 2, threaded slide bar 1 201, small-diameter B pipe 3, slide plate 2 301, slide groove 2 302, small-diameter A pipe 4, slide plate 1 401, slide groove 1 402, hinge cylinder 5, seals, and locking nuts are all existing products or structures well known to those skilled in the art, and their interconnections also adopt existing connection methods well known to those skilled in the art, which will not be described in detail here.

[0052] The method in this embodiment requires reserving rib beam openings and hollow floor slab bottom openings during the construction of the hollow floor slab. After the floor slab construction is completed, the fluid pipe is bent and extended into the hollow floor slab cavity. It is moved axially within the cavity to obtain space for adjusting the pipe length. After the pipe length is adjusted, the locking nut is tightened to control the pipe length. The fluid pipe is then moved again within the cavity and connected to the intermediate pipe C to form a Z-shaped pipe network. Referring to Figure 4, when the fluid pipe needs maintenance, the cover plate corresponding to the repair port is opened, the connection of the intermediate pipe C is disconnected, and the entire pipe is moved into the reserved space in one side of the cavity. Due to the Z-shaped pipe layout, there is no mutual interference between two adjacent pipes. The pipe is moved to the point where maintenance is required and exposed at the repair port for maintenance.

[0053] Reference Figures 13a-13c When the fluid pipeline needs to be replaced, disconnect the intermediate pipeline C, such as... Figure 13b As shown, a portion of the length of the smaller diameter pipe A4 is incorporated into the larger diameter pipe A2, and a portion of the length of the smaller diameter pipe B3 is incorporated into the larger diameter pipe B1, thus shortening the total pipe length; refer to... Figure 13c Move the entire pipe into one side of the cavity. Once the larger diameter pipe B1 or the larger diameter pipe A2 is inserted into the cavity, bend the larger diameter pipe B1 or the larger diameter pipe A2 so that it is biased towards the opening. Extend one end of the pipe outside the repair opening to remove the pipe to be replaced from the floor slab. Then replace it with the ready-to-use pipe, keeping it bent. Adjust the corresponding pipe length and insert the pipe into the floor slab through the repair opening on one side. After passing through the rib beam fixing hole, readjust the bend length and opening angle to ensure proper pipe placement and easy connection. Then connect it to other pipe fittings.

[0054] This implementation plan facilitates the replacement and maintenance of fluid pipes inside the cavity floor slab, greatly avoiding the adverse effects of having to dismantle a large area of ​​the floor slab when replacing pipes inside the cavity floor slab, improving the efficiency of pipe inspection and replacement inside the floor slab, and has high economic benefits.

[0055] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
