Description

Technical Field

[0001] The utility model belongs to the technical field of ancient buildings, and in particular relates to an outer wall of a single-layer courtyard house. Background Art

[0002] Siheyuan, also known as Sihefang, is a traditional courtyard-style building in China. Its layout is a courtyard with houses built on all four sides, enclosing the courtyard in the middle from all four sides, hence the name Siheyuan;

[0003] With the development of society, the livability of the traditional courtyard house has been challenged, so modern high-rise buildings have replaced the traditional courtyard house. However, as a traditional Chinese building, the architectural form of the traditional courtyard house has the significance of inheritance. Therefore, the new courtyard house came into being, which can not only inherit the ancient architecture but also improve the livability of the courtyard house.

[0004] When building the exterior walls of traditional courtyard houses, only ancient bricks, city bricks, large mud or small mud are used. Due to the four-sided enclosed layout of the traditional courtyard house, except for the north wing, the east, west and south wing rooms are not facing the sun. In addition, the courtyard house itself is low-lying, so the indoor moisture and humidity are high in the courtyard house located in the south, and the wooden furniture is prone to mold and rot, making it difficult to live in. Utility Model Content

[0005] The utility model aims to provide a single-layer courtyard house exterior wall, aiming to solve the problems of heavy indoor moisture, high humidity and poor livability of courtyard houses located in the south in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A single-layer courtyard house exterior wall comprises a concrete layer, a first mortar layer, a moisture-proof and heat-insulating layer, a second mortar layer and a finishing exterior wall layer which are arranged in sequence from the inside to the outside.

[0008] In a preferred embodiment of the utility model, the moisture-proof and heat-insulating layer is an extruded polystyrene board, the extruded polystyrene board and the first mortar layer are bonded by DEA mortar, and anchor bolts are added between the extruded polystyrene board and the first mortar layer.

[0009] In a preferred embodiment of the present utility model, the concrete layer is made of aerated concrete blocks, and an interface agent is coated on the back of the concrete layer.

[0010] In a preferred embodiment of the present invention, the first mortar layer is a dry-mixed plaster mortar leveling layer.

[0011] In a preferred embodiment of the present invention, the second mortar layer is a thermal insulation board plastering mortar layer.

[0012] In a preferred embodiment of the utility model, the facing exterior wall layer is constructed by large mud bricks and small mud bricks, and the large mud bricks and the small mud bricks are bonded to the second mortar layer by ceramic brick bonding mortar.

[0013] In a preferred embodiment of the utility model, during masonry, 1.0mm thick steel mesh with diamond holes of 15mmx40mm is laid horizontally every ten layers between the facing exterior wall layer and the back of the concrete layer, and No. 18 galvanized steel wire is used to tie the overlapping parts. The steel mesh is buried in the mortar layer, extends out of the moisture-proof and heat-insulating layer, and is grouted with adhesive to be tied to the facing exterior wall layer.

[0014] The beneficial effect of the utility model is that the outer wall of the courtyard house designed by the utility model includes a concrete layer, a first mortar layer, a moisture-proof and heat-insulating layer, a second mortar layer and a facing outer wall layer which are arranged in sequence from the inside to the outside. The moisture-proof and heat-insulating layer is made of extruded polystyrene board, which can play the role of moisture-proof and heat-insulating.

[0017] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0018] Example:

[0019] like Figure 1 As shown, this embodiment provides a single-layer courtyard house exterior wall, including a concrete layer 1, a first mortar layer 2, a moisture-proof and heat-insulating layer 3, a second mortar layer 4 and a finishing exterior wall layer 5 arranged in sequence from the inside to the outside.

[0020] Specifically, a moisture-proof and heat-insulating layer 3 is arranged inside the outer wall. When the external environment is relatively humid, the moisture-proof and heat-insulating layer 3 can effectively prevent moisture, avoid excessive humidity in the courtyard, and prevent the wooden furniture in the courtyard from getting moldy and rotten due to excessive indoor air humidity. At the same time, the moisture-proof and heat-insulating layer 3 can also play a role in heat preservation, energy saving, and emission reduction, ensuring that the temperature in the courtyard is warm in winter and cool in summer, and improving the livability of the courtyard without changing the traditional architectural form of the courtyard.

[0021] In this embodiment, the moisture-proof and heat-insulating layer 3 is an extruded polystyrene board, the extruded polystyrene board and the first mortar layer 2 are bonded by DEA mortar, and anchor bolts are added between the extruded polystyrene board and the first mortar layer 2.

[0022] Specifically, the extruded polystyrene board has excellent moisture-proof performance. Because its closed-pore rate is as high as over 90%, it can effectively prevent the penetration of water molecules, that is, it can effectively prevent water molecules outside the courtyard from entering the interior of the courtyard. At the same time, due to the poor water absorption performance of the extruded polystyrene board itself, the extruded polystyrene board is not easy to be affected by moisture, thereby ensuring the service life and use effect of the moisture-proof and heat-insulating layer 3. At the same time, the internal structure of the extruded polystyrene board can reduce the transmission of thermal radiation and convective heat flow, thereby effectively reducing the air flow required for the thermal balance inside and outside the building, thereby achieving the technical effects of heat preservation, energy saving, and emission reduction, and ensuring that the interior of the courtyard is warm in winter and cool in summer.

[0023] Furthermore, the extruded polystyrene board can also play a technical effect of sound insulation, reduce the noise level inside the courtyard house, and improve the livability of the courtyard house. The extruded polystyrene board uses B1 grade extruded polystyrene board, which can play a technical effect of fire retardancy.

[0024] Furthermore, the extruded polystyrene board is bonded to the first mortar layer 2 by DEA mortar, and anchor bolts are added between the extruded polystyrene board and the first mortar layer 2, and the number of anchor bolts used per square meter of extruded polystyrene board is not less than 4, so as to ensure the stability between the moisture-proof insulation layer 3 and the first mortar layer 2.

[0025] In this embodiment, the concrete layer 1 is made of aerated concrete blocks, and an interface agent is coated on the back of the concrete layer 1.

[0026] Specifically, the thickness of the aerated concrete is 200 mm, and an interface agent is coated on the back of the concrete layer 1 to facilitate the setting of the first mortar layer 2.

[0027] In this embodiment, the first mortar layer 2 is a dry-mixed plaster mortar leveling layer.

[0028] Specifically, the thickness of the first mortar layer 2 is 5-12 mm. After leveling, the moisture-proof and heat-insulating layer 3 is installed to ensure the installation effect of the moisture-proof and heat-insulating layer 3.

[0029] In this embodiment, the second mortar layer 4 is a thermal insulation board plastering mortar layer.

[0030] Specifically, the thickness of the insulation board facing mortar layer is 15 mm. The insulation board facing mortar layer can play the role of exterior wall insulation, and can also be used as a waterproof layer in a humid environment, further achieving the technical effect of moisture-proof and heat-insulating.

[0031] In this embodiment, the facing outer wall layer 5 is constructed by using large mud bricks and small mud bricks, and both the large mud bricks and the small mud bricks are bonded to the second mortar layer by ceramic brick bonding mortar.

[0032] Specifically, the large mud bricks and the small mud bricks are both non-clay and non-shale bricks, which are traditional handmade products. The specific shape of the facing exterior wall layer 5 can be set according to actual conditions.

[0033] In this embodiment, a 1.0 mm thick steel plate mesh with a diamond hole of 15 mm x 40 mm is laid horizontally every ten layers between the facing exterior wall layer 5 and the back of the concrete layer 1 during masonry construction. The overlapped parts are bound with No. 18 galvanized steel wire. The steel plate mesh is buried in the mortar layer, extending out of the moisture-proof and heat-insulating layer 3 and grouted with adhesive to tie it to the facing exterior wall layer 5, so as to ensure the stability of the courtyard's exterior wall.

[0034] Furthermore, reinforced concrete or wooden lintels are set on the tops of the door and window openings, 100 mm wide concrete auxiliary frames are set on both sides of the door and window openings, the gaps between the door and window frames and the outer walls of the courtyard are filled with polymer cement waterproof mortar or foamed polyurethane, the second mortar layer 4 extends to the door and window frames, and a groove is reserved between the second mortar layer 4 and the door and window frames, and the sealing material is embedded in the groove.

[0035] Furthermore, a wooden auxiliary frame is arranged inside the concrete auxiliary frame, and the wooden auxiliary frame and the concrete auxiliary frame are anchored by expansion bolts.

[0036] Specifically, the working principle of the single-layer courtyard house exterior wall is as follows: when constructing the utility model, a moisture-proof and heat-insulating layer 3 is arranged inside the courtyard house exterior wall body, and the moisture-proof and heat-insulating layer 3 is made of extruded polystyrene board. When installing the extruded polystyrene board, an interface agent is coated on the back of the concrete layer 1, and dry-mixed plaster mortar is used for leveling. The extruded polystyrene board is bonded to the dry-mixed plaster mortar leveling layer through DEA ​​mortar, and anchor bolts are added between the extruded polystyrene board and the dry-mixed plaster mortar leveling layer to ensure the stable installation of the extruded polystyrene board. The extruded polystyrene board can play a role in moisture-proof and heat-insulating. When the external environment is relatively humid, the moisture-proof and heat-insulating layer 3 can effectively prevent moisture and avoid excessive humidity in the courtyard house. At the same time, the moisture-proof and heat-insulating layer 3 can also play a role in heat preservation, energy saving, The effects of emission reduction and sound insulation make the temperature in the courtyard warm in winter and cool in summer. Without changing the architectural form of the courtyard, the livability of the courtyard is improved. A thermal insulation board facing mortar layer is arranged on the surface of the moisture-proof and heat-insulating layer 3. The thermal insulation board facing mortar layer can play the role of external wall insulation, and can also be used as a waterproof layer in a humid environment, further achieving a technical effect of moisture-proof. During masonry, a 1.0mm thick steel plate mesh with a diamond hole of 15mmx40mm is laid horizontally every ten layers between the facing external wall layer 5 and the back bricks of the concrete layer 1. The overlap is tied with No. 18 galvanized steel wire. The steel plate mesh is buried in the mortar layer, extends out of the moisture-proof and heat-insulating layer 3, and is grouted with adhesive to tie it to the facing external wall layer 5, so as to ensure the stability of the external wall of the courtyard.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
