Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline pre-embedded molding, and in particular relates to a one-time pre-embedded molding structure for pipelines in an assembled prefabricated component. Background Art

[0002] Comprehensive construction of pipelines in prefabricated composite slabs. Since there are many pipelines in the composite cast-in-place layer, it is inevitable that the pipelines cross each other. There are many construction workers on the on-site construction work surface, which is not only not conducive to the protection of the finished product, but also affects the finished elevation of the floor due to the superposition phenomenon. During on-site construction, for the same apartment type, the laying methods of the pipelines will be different because they are constructed by different personnel. This causes the laying paths of the pipelines in the top slab to be very random depending on the construction personnel. If pipe blockage occurs during the construction process, it will be very difficult to repair the pipelines in the later stage. There are many pipelines in the composite cast-in-place layer of the composite slab, and the overlapping parts of the wire pipes result in the thickness of the composite cast-in-place slab being greater than the original designed thickness of 70mm. In addition, the overlap of pipelines and transverse reinforcement during the construction process make the composite slab too thick, changing the design load value. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a one-time pre-buried pipeline forming structure in an assembled prefabricated component in view of the deficiencies in the above-mentioned prior art. The design is novel and reasonable. By deepening the design drawing, some PVC pre-buried pipes are arranged in the prefabricated composite board in advance, so as to reduce the number of intersections and the stacking height between the pipelines, avoid the composite board poured later exceeding the designed thickness, and at the same time ensure that the pipeline laying method of each roof plate of the same type of house on the construction site is the same, which is also convenient for the later pipeline repair and easy to promote and use.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a one-time pre-buried pipeline forming structure in an assembled prefabricated component, including a prefabricated composite plate, in which composite plate steel bars, truss steel bars and an electric box are pre-buried, and the characteristic is that a PVC pre-buried pipe connected to the electric box is also pre-buried in the prefabricated composite plate, and a sleeve is arranged on the outer surface of one end of the PVC pre-buried pipe close to the edge of the prefabricated composite plate, and the end of the sleeve away from the PVC pre-buried pipe is flush with the edge of the prefabricated composite plate.

[0005] The one-time pre-buried pipeline forming structure in the above-mentioned assembled prefabricated component is characterized in that the distance between the end of the PVC pre-buried pipe close to the edge of the prefabricated composite board and the edge of the prefabricated composite board is 10cm to 12cm.

[0006] The one-time pre-buried pipeline forming structure in the above-mentioned assembled prefabricated component is characterized in that the distance that the PVC pre-buried pipe extends into the casing is 5cm to 6cm.

[0007] The one-time pre-buried pipeline forming structure in the above-mentioned assembled prefabricated components is characterized in that: the two PVC pre-buried pipes at the corresponding positions of the edges of two adjacent prefabricated composite plates are connected by a PVC connecting pipe, and the model and size of the PVC connecting pipe are consistent with the model and size of the PVC pre-buried pipe.

[0008] The above-mentioned prefabricated prefabricated component pipeline one-time embedded forming structure is characterized in that: the thickness of the prefabricated composite board is 4 to 5 times the diameter of the PVC embedded pipe; the height of the PVC embedded pipe embedded in the prefabricated composite board is 0.5 to 0.8 times the diameter of the PVC embedded pipe.

[0009] The beneficial effects of the utility model are that the design is novel and reasonable. By deepening the design drawings, some PVC embedded pipes are arranged in the prefabricated composite panels in advance, reducing the number of intersections and overlapping heights between pipelines, avoiding the composite panels poured later to exceed the designed thickness, and ensuring that the pipeline laying methods of each roof of the same house type on the construction site are the same, which is also convenient for the later pipeline repair and easy to promote and use.

[0017] like Figure 1 and Figure 2 As shown, the one-time pre-buried pipeline forming structure in the assembled prefabricated component of the utility model includes a prefabricated composite plate 3, in which composite plate steel bars 4, truss steel bars 2 and an electric box 7 are pre-buried, and a PVC pre-buried pipe 5 connected to the electric box 7 is also pre-buried in the prefabricated composite plate 3. A sleeve 1 is provided on the outer surface of one end of the PVC pre-buried pipe 5 close to the edge of the prefabricated composite plate 3, and the end of the sleeve 1 away from the PVC pre-buried pipe 5 is flush with the edge of the prefabricated composite plate 3.

[0018] In this embodiment, the distance between the end of the PVC embedded pipe 5 close to the edge of the prefabricated composite board 3 and the edge of the prefabricated composite board 3 is 10 cm to 12 cm.

[0019] In this embodiment, the distance that the PVC pre-buried pipe 5 extends into the casing 1 is 5 cm to 6 cm.

[0020] In this embodiment, two PVC embedded pipes 5 at corresponding positions on the edges of two adjacent prefabricated composite panels 3 are connected by a PVC connecting pipe 6 , and the model and size of the PVC connecting pipe 6 are consistent with the model and size of the PVC embedded pipe 5 .

[0021] In this embodiment, the thickness of the prefabricated composite board 3 is 4 to 5 times the diameter of the PVC pre-buried pipe 5 ; the height of the PVC pre-buried pipe 5 pre-buried in the prefabricated composite board 3 is 0.5 to 0.8 times the diameter of the PVC pre-buried pipe 5 .

[0022] It should be noted that the height of the PVC embedded pipe 5 embedded in the prefabricated composite board 3 is 0.5 to 0.8 times the diameter of the PVC embedded pipe 5, wherein the top of the PVC embedded pipe 5 is exposed from the upper surface of the prefabricated composite board 3, so that on-site construction personnel can quickly find the PVC embedded pipe 5 to carry out subsequent construction processes.

[0023] When the utility model is used, part of the PVC embedded pipes are arranged in the prefabricated composite board in advance through the in-depth design drawing, so as to reduce the number of intersections and the overlapping height between the pipelines, avoid the composite board cast later exceeding the designed thickness, and at the same time ensure that the pipeline laying method of each roof plate of the same apartment type on the construction site is the same, which is also convenient for the later pipeline repair. The remaining wire pipes on the prefabricated composite board are constructed on the construction site after the prefabricated composite board 3 is connected. According to the in-depth design drawing, the remaining wire pipes are connected to the electric box 7, thereby simplifying the pipeline connection construction on the construction site. During actual construction, different types of PVC embedded pipes 5 can be distinguished by color, and the on-site construction is installed and connected according to the in-depth design drawing and the same color.
