Description

A pre-buried floor drain

technical field

The utility model relates to a floor drain, in particular to a pre-embedded floor drain.

Background technique

When pouring the front of the floor, the floor drain is usually placed on the formwork where the floor drain needs to be installed, poured together when the floor is poured, and pre-buried in the floor to facilitate the installation of pipes later. However, the concrete still has a certain fluidity before solidification. Due to the insufficient fixation force between the outer wall of the floor drain and the cement concrete, there is a gap between the floor drain and the cement concrete, which may easily cause deashing, delamination, and Leakage phenomenon.

Utility model content

In order to overcome the above-mentioned defects in the prior art, the utility model provides a pre-embedded floor drain with convenient construction and tight and reliable connection with the formwork.

Provided is a pre-embedded floor drain, comprising a floor drain main body, a straight pipe and a fixed chassis connected in sequence, a part of the straight pipe extends into the floor drain main body, a part is closed and connected with the lower end of the floor drain main body and extends out of the floor drain main body; the straight pipe protrudes The outer wall of the main part of the floor drain is provided with threads, and the bottom of the fixed chassis is provided with a groove; the bottom of the fixed chassis is provided with a temporary dust-proof cover.

By providing threads on the straight pipe and grooves at the bottom of the fixed chassis, it is beneficial to increase the fixing force between the fixed chassis and cement concrete or wall plaster.

Preferably, the outer wall of the main body of the floor drain, the outer wall of the straight pipe and the outer wall of the fixed chassis are all etched. Through the etching treatment, the friction force between the embedded floor drain and the concrete contact surface is increased, and the fixing force of the embedded floor drain in the concrete is further improved.

Preferably, the thread is a rectangular thread.

Preferably, the depth of the thread is 1.0 ~ 3.0 cm.

Preferably, the pitch of the thread is 0.5-2.0 cm.

Preferably, the ratio of the depth of the groove to the thickness of the fixed chassis is 1:2~5.

Preferably, the outer wall of the floor drain main body is provided with a water stop groove. The water stop can prevent water from passing through

Leakage through the gap between the outer wall of the main body of the floor drain and the concrete.

Compared with the prior art, the beneficial effects of the utility model are:

The pre-embedded floor drain described in the utility model, by providing threads on the outer wall of the straight pipe, increases the fixing force between the cement concrete and the pre-embedded floor drain, avoids the gap between the pre-embedded floor drain and the cement concrete, and makes the connection of the pipeline at the bottom of the building The place will not be prone to deashing, delamination and leakage.

Description of drawings

Fig. 1 is a structural schematic diagram of the embedded floor drain of the present invention.

Detailed ways

The utility model will be further described below in conjunction with specific embodiments. Wherein, the accompanying drawings are for illustrative purposes only, and represent only schematic diagrams, rather than actual drawings, and should not be construed as limitations on this patent; in order to better illustrate the embodiments of the present utility model, some parts of the accompanying drawings will be omitted , enlargement or reduction, do not represent the size of the actual item; for those skilled in the art, it is understandable that some known structures and their descriptions in the drawings may be omitted.

Example 1

As shown in Figure 1, a pre-embedded floor drain includes a floor drain main body 1, a straight pipe 2 and a fixed chassis 3 connected in sequence, a part of the straight pipe 2 extends into the floor drain main body 1, and a part is closed and connected to the lower end of the floor drain main body 1 and extends The main body of the floor drain. The outer wall of the floor drain main body 1 is provided with a water stop groove 4 , the floor drain main body 1 is provided with a floor drain outer cover 5 and a floor drain inner cover 6 , the floor drain outer cover 5 is provided with a water inlet 51 , and the floor drain outer cover 5 is set on the straight pipe 2 and extends into the floor drain main body 1, a first compartment is formed between the floor drain cover 5 and the outer wall of the straight pipe 2, the floor drain cover 5 and the floor drain main body 1 form a second compartment, and the bottom of the first compartment and the second compartment The bottom of the floor drain is connected, and the floor drain inner cover 6 is embedded in the floor drain outer cover 5, and communicated with the first compartment. When the inner cover of the floor drain is not opened, the water enters the second interlayer from the water inlet. Since the bottom of the first interlayer communicates with the bottom of the second interlayer, only the water inside the main body of the floor drain rises to a certain The water inlet of pipe 2 will enter the straight pipe at this moment and be drained away. When the water does not cross the water inlet of the straight pipe, it will be temporarily stored in the main body of the floor drain to play the role of deodorization.

The outer wall of straight pipe 2 is provided with rectangular thread 7, and the depth of thread 7 is 2.0 cm, and the pitch of screw thread is 0.8 cm; The bottom of fixed chassis 3 is provided with 3 road grooves 8, and the depth of groove and the thickness of described fixed chassis The ratio is 1:2. The four corners of the fixed chassis are provided with nail holes 9, which are fixed on the formwork on the floor where the floor drain needs to be installed by nails, and the bottom of the fixed chassis is also provided with a temporary dust cover 10.

Apparently, the above-mentioned embodiments of the present utility model are only examples for clearly illustrating the present utility model, rather than limiting the implementation manner of the present utility model. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. All modifications, equivalent replacements and improvements made within the spirit and principles of the utility model shall be included in the protection scope of the claims of the utility model.
