Description

Technical Field

[0001] The utility model belongs to the technical field of pre-buried wire tubes in floor slabs, and particularly relates to a combined installation structure for wire tubes in floor slabs. Background Art

[0002] During the floor construction process, there is a lot of wire and pipe laying work. Since the steel mesh is installed in the floor, especially in the steel truss floor decking, the construction area is large, and rigid conduits such as galvanized steel pipes are used to pass through the trusses. The laying space is small, the construction is difficult and the efficiency is low, which affects the progress of the main construction.

[0003] In addition, vertical wire pipes need to be installed in the floor slab to connect with the wire pipes in the subsequent vertical components such as wall panels. During the pouring of the floor slab structure and the removal of the formwork, it is easy to cause damage or displacement to the exposed part of the vertical wire pipe, affecting the subsequent wire pipe connection. The traditional protection measure is to use a PVC pipe that is two sizes larger than the pipe mouth to pour mortar to protect the pipe mouth. This method is complicated to operate, time-consuming and labor-intensive, and not easy to recycle.

[0004] In addition, the vertical wire pipes should also be blocked to prevent concrete or other debris from entering the vertical wire pipes. In the prior art, tape is usually used to block the pipe openings. Although this method is convenient and fast, the blocking is unreliable and there are hidden dangers in construction quality.

[0024] like Figure 1-4 As shown, the utility model provides a combined installation structure for wire pipes in a floor slab, comprising a bendable metal pipe 1, a steering pipe 2, a protective member 4 and a blocking member 5; the bendable metal pipe 1 is laid in the floor slab; the steering pipe 2 is an L-shaped pipe, comprising a horizontal pipe 21 and a vertical pipe 22, the horizontal pipe 21 is connected to the bendable metal pipe 1 through a connecting member 3, and the top end of the vertical pipe 22 extends out of the top surface of the floor slab for subsequent connection of wire pipes in vertical components; the protective member 4 comprises vertical ribs 41 and connecting ribs 42, the vertical ribs 41 are arranged at intervals around the vertical pipe 22, and the connecting ribs 42 connect all the vertical ribs 41 as a whole; the blocking member 5 comprises a positioning cover 51 and a sealing plug 52; the positioning cover 51 is formed by connecting a sleeve and a top plate, the top plate is provided with a reserved hole corresponding to the vertical rib 41, and is sleeved on the vertical rib 41 through the reserved hole, and the sleeve is sleeved on the vertical pipe 22; the sealing plug 52 is arranged at the bottom of the top plate, and is inserted into the vertical pipe 22 to achieve the blocking of the vertical pipe 22.

[0025] The vertical ribs 41 of the protective member 4 are connected to the vertical pipe 22 through the blocking member 5 to support and protect the vertical pipe 22 and prevent the vertical pipe 22 from being damaged during later construction.

[0026] The inner wall of the bendable metal pipe 1 is coated with a thermosetting powder coating. The powder is evenly adsorbed on the bendable metal pipe 1 through electrostatic spraying, and then liquefied and solidified by high temperature heating at 200°C to form a dense and stable coating. The coating itself has the characteristics of insulation, corrosion resistance, flame retardancy, and wear resistance. The thickness is 0.03mm. When in use, the bendable metal conduit can be bent to the required degree by applying appropriate force by hand, reducing the difficulty of laying the pipeline.

[0027] The steering tube 2 is a galvanized steel tube.

[0028] The vertical reinforcement 41 is tied and fixed to the steel bars in the floor slab. When the distance between the vertical reinforcement 41 and the steel bars in the floor slab is difficult to tie and connect, auxiliary reinforcement is set to be welded to the steel bars in the floor slab. Preferably, three vertical reinforcements 41 are arranged at intervals in the annular direction. The connecting reinforcement 42 is a ring reinforcement, and its size is larger than the size of the vertical pipe 22.

[0029] The sealing plug 52 is set to be an inverted truncated cone, that is, the diameter decreases from top to bottom, so that the sealing plug 52 can be matched with vertical pipes 22 of various calibers, which is convenient for the turnover of the sealing member 5. Preferably, the sealing plug 52 is a wooden plug to ensure tight sealing. The bottom of the sleeve of the positioning cover 51 is higher than the construction completion surface of the floor slab.

[0030] During construction, first lay the flexible metal tube 1 according to the design drawings, and then connect the steering tube 2 and the flexible metal tube 1 through the connecting piece 3; put the protective piece 4 on the vertical tube 22 of the steering tube 2 and fix it; make the reserved hole of the positioning cover 51 correspond to the vertical rib 41, and insert it so that the sealing plug 52 fits tightly with the vertical tube 22. At this time, the laying and protection of the wire tube are completed, and concrete pouring can be carried out. After the construction is completed, the sealing piece 5 is removed and the sealing piece 5 can be reused.
