Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a telescopic pre-buried wire pipe protection joint. Background Art

[0002] As an important link that cannot be avoided in water and electricity installation, pre-buried water and electricity plays a key role in the later installation. If it is damaged, it will bring great trouble and hidden dangers to the later installation, so the protection of its finished products is very important. However, due to the cross-construction of various processes during construction, the site is limited, and the pre-buried wire pipes are usually made of relatively fragile materials such as PVC, damage cannot be completely avoided. No matter how strict the control measures are, they can only minimize the damage rate.

[0003] The existing finished product protection measures are basically added later, such as tape sealing (or direct wire pipe cover) and mortar protection. The purpose of tape sealing is usually to prevent mortar from entering the pipeline during concrete pouring, causing blockage, and it cannot avoid mechanical damage such as trampling and bumping. Mortar protection can effectively support vertical destructive force, but in order to facilitate later connection, the mortar cannot be completely bonded to the ground, and the horizontal destructive force cannot be effectively resisted. In addition, due to its own large size, it will cause inconvenience in construction. At the same time, the protective mortar can only be cleaned up as construction waste in later construction, causing waste. When the finished product is damaged due to inadequate protection, since a certain connection margin must be left for the pipeline connection, the concrete floor around the pipeline is usually chiseled out to increase the connection margin when connecting the pipeline. While causing waste of manpower, the damage to the concrete floor cannot be underestimated. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the utility model provides a telescopic pre-buried wire pipe protection joint, which is easy to implement and improves construction efficiency. It can also protect the pre-buried wire pipe from being damaged throughout the whole process and is easy to repair after being damaged, thereby reducing the losses caused by later repairs.

[0005] To achieve the above object, the utility model provides a telescopic pre-buried wire pipe protection joint, which is characterized by comprising an inner lining pipe, a middle telescopic pipe and an outer protection pipe;

[0006] The telescopic tube is sleeved on the outer sides of the pre-buried wire tube and the inner lining tube, and is in a compressed state in the protection state;

[0007] The protection tube is sleeved on the outside of the telescopic tube, and a support platform of the telescopic tube is provided at the bottom end;

[0008] The inner lining pipe and the protective pipe are integrally formed, and the cross section thereof is a U-shape with a staggered portion; the staggered portion is arranged at a position where the bottom of the inner lining pipe is aligned with the pipe opening of the pre-buried wire pipe;

[0009] The protection joint is fixedly connected to the pre-buried wire tube by adhesive; in the protection state, the top of the three-layer structure is sealed by a detachable cover.

[0010] One end of the protective joint is a detachable cover, and the other end is connected to the pre-buried wire pipe, and the size is matched with the pre-buried wire pipe. The detachable cover can effectively prevent mortar from entering the pipeline during concrete pouring. After removing the cover, it is no different from an ordinary wire pipe, which is convenient for later connection. The retractable pipe pops out when the cover is opened or the part above the ground is damaged, so as to facilitate the connection with the above-ground wire pipe.

[0011] Furthermore, the inner liner tube and the protective tube are integrally formed, and the cross section thereof is a U-shape with a staggered step; the staggered step allows the bottom of the inner liner tube to be aligned with the pipe opening of the pre-buried wire tube.

[0012] Furthermore, the upper part of the telescopic tube is a PVC tube, and the lower part is provided with an elastic filler.

[0013] Furthermore, the elastic filler is a spring tube.

[0014] Furthermore, the inner diameter of the lining tube is consistent with the inner diameter of the pre-buried wire tube, which better ensures smooth threading in the later stage.

[0015] Furthermore, the detachable cover is detachably fixedly connected to the protective joint via a fixing buckle inside the cover.

[0016] Compared with the prior art, the utility model has the following advantages or beneficial effects:

[0017] (1) The utility model can also repair the damaged wire pipe port while ensuring that the wire pipe will not cause mortar blockage, thereby avoiding the waste of manpower and damage caused by floor slab chiseling;

[0018] (2) The above-ground part of the utility model has three layers, and its strength is significantly enhanced, and it is not easily damaged by conventional kicking;

[0019] (3) The structure of the utility model is easy to manufacture and the method of use is simple and easy. Compared with the traditional finished product protection method, it can reduce the manpower consumption caused by secondary construction, mortar waste and transportation costs.

[0027] Example

[0028] See also Figure 1 and Figure 2 , this embodiment provides a telescopic pre-buried wire pipe protection joint, including an inner lining pipe 1, a middle telescopic pipe 2 and an outer protection pipe 3;

[0029] The telescopic tube 2 is sleeved on the outer sides of the pre-buried wire tube 10 and the inner lining tube 1 and is in a compressed state in the protection state;

[0030] The protection tube 3 is sleeved on the outside of the telescopic tube 2, and a support 31 of the telescopic tube 2 is provided at the bottom end;

[0031] The inner lining tube 1 and the protective tube 3 are integrally formed, and the cross section thereof is U-shaped with a staggered platform 11; the staggered platform 11 is arranged at the position where the bottom of the inner lining tube 1 is aligned with the pipe opening of the pre-buried wire tube 10;

[0032] The protection joint is fixedly connected to the pre-buried wire tube 10 by adhesive; in the protection state, the top of the three-layer structure is sealed by a detachable cover 4.

[0033] One end of the protective joint is a detachable cover, and the other end is connected to the pre-buried wire pipe, and the size is matched with the pre-buried wire pipe. The detachable cover can effectively prevent mortar from entering the pipeline during concrete pouring. After removing the cover, it is no different from an ordinary wire pipe, which is convenient for later connection. The retractable pipe pops out when the cover is opened or the part above the ground is damaged, so as to facilitate the connection with the above-ground wire pipe.

[0034] As a preferred technical solution, further: the upper part of the telescopic tube 2 is a PVC tube, and the lower part is provided with an elastic filler 21. Preferably, the elastic filler is a spring tube. It is understandable that the elastic filler can also be other elastic filling materials that can achieve compression and rebound.

[0035] As a preferred technical solution, further: the inner diameter of the lining tube 1 is consistent with the inner diameter of the pre-buried wire tube 10, so as to better ensure smooth threading in the later stage.

[0037] The protection joint is used as a wire pipe port joint and protection device when the pipeline is pre-buried. When pre-buried, the bottom end in the concrete slab 5 is connected to the port of the pre-buried wire pipe 10, and the rest is exposed to the ground. Before the top of the wire pipe 6 is installed, the joint is used as a protection device to protect the wire pipe from being contaminated, blocked or damaged. Figure 3 When installing the top access wire pipe 6, the cover can be directly removed, the telescopic pipe 2 pops out, and the access wire pipe 6 is installed on the inner side of the telescopic pipe 2, aligned with the inner lining pipe 1. When the upper part is deformed due to external force but not broken, the upper part of the board can be cut along the ground during installation, and the popped-out telescopic pipe 2 is used to connect the inner lining pipe 1. When the damage is serious (the upper part of the board is completely broken) and the installation conditions are not met, a flat material such as a wooden board can be used to cover the joint to ensure that no impurities fall into the pipe. At the same time, the telescopic pipe 2 can be pressed into the joint to ensure its completion and facilitate later construction.

[0038] In summary, the utility model provides a telescopic pre-buried wire pipe protection joint, including an inner lining pipe, a middle telescopic pipe and an outer protective pipe; the telescopic pipe is sleeved on the outside of the pre-buried wire pipe and the inner lining pipe, and is in a compressed state in the protection state; the protective pipe is sleeved on the outside of the telescopic pipe, and a base for the telescopic pipe is provided at the bottom; the inner lining pipe and the protective pipe are integrally formed, and the cross-section is a U-shape with a misalignment; the misalignment is provided at the position where the bottom of the inner lining pipe is aligned with the pipe mouth of the pre-buried wire pipe; the protection joint is fixedly connected to the pre-buried wire pipe by an adhesive. The structure of the utility model is easy to implement, improves construction efficiency, and can protect the pre-buried wire pipe from being damaged throughout the whole process, and is easy to repair after it is damaged, which can reduce the loss caused by later repairs.
