Description

A portable anti-leakage concrete layer drainage pipe connection pre-embedded device

technical field

The utility model relates to a drainage pipe fitting, in particular to a portable concrete layer drainage pipe material connection pre-embedded device capable of preventing leakage.

Background technique

In multi-story residential buildings, the sewage and roof rainwater of each residential user are mainly collected through the plastic drainage pipe network, and then discharged to the municipal sewage pipe network. In multi-story residential buildings, the connection of drainage pipes between floors becomes the building drainage connection key.

The current practice is to use the method of pre-installing the drainage pipe channel in the concrete layer, that is, in the process of pouring concrete, a small section of drainage pipe of equal diameter is pre-embedded on the formwork layer and inside the steel bar layer, in order to prevent the concrete from being damaged during the pouring process. To block the pre-embedded drainage pipe, it is necessary to seal and fill the pre-embedded drainage pipe with fluffy rolls such as waste plastic bags and cement bags. The drainage pipe is knocked out to form a preset drainage pipe connection channel with the outer diameter of the drainage pipe to be connected; when installing the drainage pipe and fittings, the hydropower installer will vertically pass the drainage pipe through the drainage channel reserved for the concrete layer. Realize the three-dimensional connection between multi-floor drainage pipes. There are two main disadvantages in this treatment method. One is that after the drainage pipes are installed in the reserved channel of the concrete layer, the anti-seepage and anti-leakage treatment measures are often improper, which will cause the joints of the floor drainage pipes to be damaged. Water seepage increases the conflict between users on the floors; the other is to use the method of pre-embedding to form drainage pipe channels in the concrete layer. Leakage measures, etc., the labor cost is relatively large. 

Utility model content

The technical problem to be solved by the utility model is to provide a portable anti-leakage concrete layer drainage pipe connection pre-embedded device that can solve the problem of water leakage at the connection of the floor drainage pipe and greatly reduce the construction cost.

The utility model is achieved in the following way: a portable anti-leakage concrete layer drainage pipe connection pre-embedded device, including a fixed seat, an upper connection port, a lower connection port, an anti-seepage groove and a leak-proof ring, the pre-embedded The device is fixed by the fixing seat, the upper connection is bonded to the outside of the drain pipe above the concrete pouring layer, the lower connection is bonded to the outside of the drain pipe below the concrete pouring layer, and the anti-seepage groove is set at the outer edge of the bottom of the upper connection to prevent The leakage ring is arranged on the inner side of the lower connecting port.

Several raised fixing reinforcement rings are arranged between the anti-seepage groove and the fixing seat.

The fixing seat is provided with four fixing holes, and the embedded device is fixed on the formwork by iron nails, and the diameter of the fixing seat is larger than that of the upper connection port and the lower connection port.

The upper connection port and the lower connection port are sealed and connected to the drain pipe by glue bonding.

The utility model can prevent leakage of the portable concrete layer drainage pipe connection pre-embedded device has the following advantages: the key point of the design of the utility model is that it has the function of bonding with the drainage pipe, before concrete pouring, the pre-embedded device The embedded device is fixed on the formwork. After the concrete pouring is completed, the embedded device and the concrete layer form an organic integral structure. The outer wall of the embedded device is closely connected with the concrete, and the inner wall can be connected with the drainage pipe. There is no need to form a reserved channel for the installation of the drainage pipe. It not only solves the problem of water leakage at the connection of floor drainage pipes, but also greatly reduces the construction cost.

Detailed ways

The utility model will be described in detail below in conjunction with specific embodiments.

Please refer to Figures 1 and 2, which is a portable anti-leakage concrete layer drainage pipe connection pre-embedded device described in the utility model, including a fixing seat 1, an upper connection port 2, a lower connection port 3, an anti-seepage Seepage groove 4 and leak-proof ring 5, four fixing holes are arranged on the fixing base 1, the embedded device is fixed on the formwork 10 by iron nails, and the upper connection port 2 is bonded to the drainage pipe above the concrete pouring layer 11 21 outside, the lower connection port 2 is glued on the outside of the drain pipe 22 below the concrete pouring layer 11, the anti-seepage groove 4 is arranged at the outer edge of the bottom of the upper connection port 2, and the leak-proof ring 5 is arranged on the inner side of the lower connection port 3. Between the anti-seepage groove 4 and the fixing seat 1, a plurality of raised fixing reinforcing rings 6 are arranged.

The diameter of the fixing seat 1 is larger than the diameter of the upper connection port 2 and the lower connection port 3, which can ensure that the embedded device is fixed in the horizontal and vertical directions in the concrete pouring layer; the upper connection port 2 is bonded to the drainage above the concrete pouring layer 11 The pipe 21 and the lower connection port 3 are bonded to the drainage pipe 22 below the concrete pouring layer 11, so that the embedded device and the concrete layer form an organic whole without dismantling, and the upper connection port and the lower connection port of the embedded device can be bonded by glue The method is sealed with the drain pipe to ensure that the connection layer of the drain pipe does not leak; the anti-seepage groove 4 has the same function as the fixing seat 1 to ensure that the embedded device is fixed in the horizontal and vertical directions in the concrete layer at the same time, and it can also prevent the concrete upper layer from leaking. The fluid leaks from the gap between the outer wall of the upper connection port of the embedded device and the concrete layer; the design of the leak-proof ring 5 can effectively prevent the fluid from leaking from the gap between the inner wall of the lower connection port and the outer wall of the connected drainage pipe; The function of ring 6 is to strengthen the fixed connection between the embedded device and the concrete, increase the friction resistance between the concrete and the outer wall of the embedded device, and further reduce fluid leakage while strengthening the organic integration between the embedded device and the concrete probability.
