Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an external wall ventilating plate. Background Art

[0002] At present, the exterior walls of buildings are generally equipped with insulation layers to increase the building's thermal insulation capacity and improve the living experience of indoor owners. However, since the insulation layer is relatively closed as a whole, the air permeability of the finishing layer (such as paint coating) outside the insulation layer is also relatively poor, making it difficult for the water vapor that leaks into the insulation layer and the wall to be discharged in time, and the wall is in a humid state for a long time. This not only easily leads to the bulging and falling off of the insulation layer and even the finishing layer of the exterior wall, but also easily leads to the deterioration of the wall.

[0003] The related research on the external wall ventilation device in the prior art, such as the exhaust and drainage structure used for the installation of a composite insulation integrated panel in patent application CN211447558U, can achieve the discharge of water vapor accumulated between the insulation layer and the wall by embedding hollow pipes in the external wall as exhaust and drainage components (in this case, the pipes run through the finishing layer and the insulation layer), and the downward setting of the end of the pipe facing the outside world can prevent rainwater from flowing back into the insulation layer and the wall to a certain extent, thereby ultimately improving the overall moisture-proof and breathable effect.

[0004] However, when installing pipe fittings in the prior art, it is often necessary to drill oblique holes first. During the drilling process, it is easy to have problems such as inaccurate hole positions, uneven use, and drill bit breakage, which makes the overall construction operation convenient and the construction efficiency average. At the same time, most of the pipe fittings in the prior art are straight pipe fittings. When the rainfall is too heavy, there is a problem that rainwater directly splashes through the pipe fittings to between the insulation layer and the wall, causing further damage to the exterior wall, which ultimately makes the improvement in moisture-proof and breathable effects still limited.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to provide an exterior wall ventilation plate to solve the technical problem that when installing pipe fittings in the prior art proposed in the above-mentioned background technology, it is often necessary to first perform an inclined hole drilling operation, resulting in the general convenience and efficiency of the overall construction operation, and most of the pipe fittings in the prior art are straight pipe fittings. When the rainfall is too heavy, rainwater can easily splash directly through the pipe fittings to between the insulation layer and the wall, causing further damage to the exterior wall, ultimately resulting in limited improvement in the moisture-proof and breathable effect.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An external wall air permeable plate comprises a plate body, wherein the plate body is a vertically arranged double-layer truncated cone structure which is narrow inside and wide outside and is hollow inside to form an air permeable cavity, an inner hole and an outer hole are respectively provided at positions corresponding to the air permeable cavity on the inner wall and the outer wall of the plate body, the inner hole is higher than the outer hole and the area of ​​the inner hole is larger than the area of ​​the outer hole, and a water retaining plate is horizontally fixed in the air permeable cavity at a height position between the outer hole and the inner hole on the inner surface of the inner wall of the plate body.

[0009] Furthermore, the disk body includes an embedded seat and a breathable seat, the embedded seat is a cap-shaped structure and the breathable seat is a disc-shaped structure, the outer hole is opened on the breathable seat, the transverse cross-section of the embedded seat is a convex structure and includes a vertically arranged truncated cone section and a circular ring section, the interior of the truncated cone section is hollow and has an open structure at one end facing outward, the inner hole is opened on the inner wall of the truncated cone section, the water baffle is horizontally fixed to the inner surface of the inner wall of the truncated cone section, the inner circumferential wall of the truncated cone section is protruding relative to the water baffle, and the two end portions of the water baffle are also fixed to the inner circumferential wall of the truncated cone section, and the circular ring section is formed by an integral circumferential vertical extension outward from the end edge of the open end of the truncated cone section.

[0010] Furthermore, the circular ring segment and the air-permeable seat are arranged in the following two ways: first, a mounting hole matching the air-permeable seat is formed on the inner wall side of the circular ring segment, and the air-permeable seat is embedded in the inner wall side of the circular ring segment through the mounting hole and abuts against the end of the open end of the conical segment; second, the air-permeable seat is integrally arranged on the inner wall side of the circular ring segment and abuts against the end of the open end of the conical segment.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model is based on the fact that the pan can be embedded in the outer wall as a component for exhaust and drainage. By vertically setting the pan to a double-layer truncated cone structure with a narrow inner side and a wide outer side, the construction work before the pan is installed is facilitated, that is, only a straight hole needs to be opened on the outer wall and chamfered, and there is no need to perform an oblique hole operation, which greatly improves the convenience and efficiency of the overall construction operation. On this basis, the air permeable cavity inside the pan, the inner and outer holes opened on the inner and outer walls of the pan at the position corresponding to the air permeable cavity, and the water retaining plate in the air permeable cavity are arranged in coordination, so as to achieve the gap between the insulation layer and the wall. The accumulated water vapor is discharged, and the height difference is used to prevent rainwater from flowing back into the space between the insulation layer and the wall. At the same time, it effectively solves the problem that when the rainfall is too heavy, rainwater directly splashes between the insulation layer and the wall through the pipe fittings, causing further damage to the outer wall. That is, when the water retaining plate is horizontally fixed to the inner surface of the inner wall of the disk and is located at a height position between the outer hole and the inner hole, it forms a water retaining dam, so that the splashing rainwater can only accumulate under the water retaining plate and be discharged from the outer hole, ultimately making the overall moisture-proof and breathable effect fully improved, greatly extending the overall service life of the outer wall and even the building.

[0013] 2. The disc body in the utility model includes an embedded seat with a hat-shaped structure and a breathable seat with a disc-shaped structure. The embedded seat includes a vertically arranged truncated cone section and a circular ring section. The utility model is based on the fact that the water retaining plate is horizontally fixed to the inner surface of the inner wall of the truncated cone section and both end portions are fixed to the inner circumferential wall of the truncated cone section. Through the coordinated arrangement of the inner circumferential wall of the truncated cone section protruding relative to the water retaining plate, the water retaining plate acts as a water dam for external rainwater, and at the same time, the water vapor circulation from the inner hole to the outer hole is effectively guaranteed, thereby further ensuring the moisture-proof and breathable effect.

[0014] 3. The area of ​​the inner hole in the utility model is larger than the area of ​​the outer hole. While ensuring the outward discharge of water vapor accumulated between the insulation layer and the wall, thereby fully ensuring the discharge effect of water vapor, it further effectively prevents external water vapor and even rainwater from entering between the insulation layer and the wall, and ultimately further improves the overall moisture-proof and breathable effect. At the same time, the shapes of the inner hole and the outer hole of the utility model can be set as needed, which further ensures the overall moisture-proof and breathable effect.

[0022] The utility model will be further described below in conjunction with the accompanying drawings of the specification. Example

[0023] See also Figure 1 to Figure 5 This embodiment provides an exterior wall ventilation plate, including a vertically arranged embedded seat 5 and a ventilation seat 6, the embedded seat 5 is a hat-shaped structure, the ventilation seat 6 is a disc-shaped structure, and the embedded seat 5 and the ventilation seat 6 together form a double-layer frustum structure that is narrow inside and wide outside.

[0024] Furthermore, an outer hole 2 is provided on the breathable seat 6, and the embedded seat 5 includes an internally hollow conical section 51. The outward end of the conical section 51 is an open structure and an inner hole 1 is provided on the inner wall. A water baffle 4 is horizontally fixed to the inner surface of the inner wall of the conical section 51 below the inner hole 1. The water baffle 4 is arranged higher than the outer hole 2 and both ends are fixed to the inner circumferential wall of the conical section 51. The inner circumferential wall of the conical section 51 is protruding relative to the water baffle 4. The end edge of the outward end of the conical section 51 extends outward in an integrated manner to form a circular ring section 52. The transverse cross-sections of the conical section 51 and the circular ring section 52 together present a convex structure.

[0025] Furthermore, a mounting hole 521 for accommodating the air-permeable seat 6 is formed on the inner wall side of the circular segment 52. The air-permeable seat 6 is embedded in the inner wall side of the circular segment 52 through the mounting hole 521. The end of the open end of the conical segment 51 is in contact with the air-permeable seat 6. The air-permeable seat 6, the conical segment 51, and the circular segment 52 together enclose a breathable cavity 3.

[0026] Installation of the air permeable plate: First, clean the wall (not shown), then make holes and chamfers on the insulation board system (not shown, including the insulation layer and its external finishing layer), and clean the dust in the hole. Then, after the inner wall of the annular segment 52 is mortared, install the embedded seat 5 together with the entire air permeable plate into the opened hole (at this time, the truncated cone segment 51 is on the inside, the air permeable seat 6 is on the outside, and at the same time, ensure that the inner hole 1 is on the top and the outer hole 2 is on the bottom). Finally, roll the interface agent, scrape the three-axis reinforcement mortar, press the mesh, and scrape the three-axis reinforcement mortar surface layer twice. During the whole process, an exhaust pipe can also be inserted into the outer hole 2 to improve the ventilation effect.

[0027] During operation, the moisture between the insulation layer and the wall first enters the air cavity 3 through the inner hole 1, and then is discharged from the outer hole 2. In addition, the setting of the inner hole 1 higher than the outer hole 2 can effectively prevent rainwater from flowing back into the insulation layer and the wall by utilizing the height difference; and the setting of the water retaining plate 4 based on this can form a water retaining dam, so that the rainwater splashing into the air cavity 3 can only accumulate under the water retaining plate 4 and be discharged from the outer hole 2, which ultimately greatly improves the moisture-proof and air-permeable effect. Example

[0028] See also Figure 6 This embodiment provides a grinding plate with a slurry conveying channel, which is different from the first embodiment only in that the air-permeable seat 6 is integrally arranged on the inner wall side of the circular ring segment 52 .

[0029] Other structures and the connection relationship between structures are the same as in Example 1.
