Description

One-way drain valve for assembled external wall panel

Technical Field

The utility model relates to an assembly type structure construction technical field especially relates to a one-way drain valve for assembled side fascia.

Background

Fabricated buildings have become of interest since the beginning of the 20 th century and have been realized through the sixties. The first attempts made in English, French, Soviet Union, etc. The assembly type building has high construction speed and low production cost, and is rapidly popularized and developed all over the world.

Early fabricated buildings were rather rigid and uniform in appearance. Later improvements in design have resulted in increased flexibility and versatility to allow modular construction not only in batch, but also in a wide variety of styles. The movable dwelling house is an advanced assembly type building in America, each dwelling unit is like a large trailer, and the movable dwelling house can be used only by pulling the movable dwelling house to the site by a special automobile and then hoisting the movable dwelling house to a floor cushion block by a crane to be connected with a pre-buried water channel, a power supply and a telephone system. The movable dwelling house is internally provided with facilities such as a heating system, a bathroom, a kitchen, a dining room, a bedroom and the like. The movable dwellings can be formed into a unit independently or can be connected with each other.

The assembled outer wall is one of the types of building parts, and in the assembling process of the assembled outer wall, a water channel needs to be reserved, so that the water vapor accumulation caused by the internal and external temperature difference is avoided, and a water drainage hole is arranged at a joint part in the gluing process, so that water in a splicing seam can be drained out of the wall body. The existing drain holes are plastic drain holes, and water can enter from the outside to the inside, so that water is accumulated in wall seams in heavy weather.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the existing drain holes are plastic drain holes, water can enter from the outside to the inside, and water is accumulated in wall joints when strong wind and heavy rain occur, and in order to solve the technical problem, the one-way drain valve for the assembled external wall panel is provided, which comprises the assembled external wall panel, the abutted seams, the drain holes and the drain valve;

the assembled external wall panels are connected through the sealant, drain holes are formed in the abutted seams, and drain valves are arranged in the drain holes.

Preferably, the inside of the drain valve adopts an elastic rubber sheet.

Preferably, the drainage valve can be changed into a one-way valve by adopting an elastic rubber sheet.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses drainage device is the check valve design, and rubber elastic cover plate can be isolated externally with outside rainwater, and inside can outwards discharge steam again. The elastic rubber sheet is adopted inside the drain valve, the drain valve can be changed into a one-way valve, water can be drained from inside to outside, external water vapor cannot permeate into the inner joint of the wall, and the inner drying, water resistance and air permeability of the outer wall joint are guaranteed.

Detailed Description

The invention is further described with reference to the accompanying drawings and examples.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "vertical", "horizontal", "up", "down", "front", "back", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-5, a one-way drain valve for an assembled external wall panel includes an assembled external wall panel 1, a splice 2, a drain hole 3, and a drain valve 4;

the assembly type external wall panel structure is characterized in that a splicing seam 2 is reserved between the assembly type external wall panels 1, sealant 21 is filled in the splicing seam 2, the assembly type external wall panels 1 are connected through the sealant 21, a drain hole 3 is arranged in the splicing seam 2, and a drain valve 4 is arranged in the drain hole 3.

For better drainage, the utility model discloses still include the inside elastic rubber piece that adopts of drain valve 4. The drain valve 4 can be changed into a one-way valve by adopting an elastic rubber sheet.

The working principle is as follows: the utility model discloses an with the inside elastic rubber piece that adopts of drain valve 4, can become drain valve 4 into the check valve, only can discharge water from inside to outside, piece 2 in the unable infiltration wall of outside steam has guaranteed 2 inside drying of outer wall piece, waterproof ventilative.

The above-mentioned embodiments only express the preferred embodiments of the present invention, and the description thereof is more specific and detailed, but the present invention is not limited to these embodiments, and it should be noted that it is obvious to those skilled in the art. Without departing from the spirit of the present invention, any improvement is within the scope of the present invention.
