Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation enclosure structures for wooden houses, and in particular relates to a double-sided sandwich thermal insulation zero thermal bridge enclosure structure for wooden houses. Background Art

[0002] The existing wooden house wall enclosure structure is mostly designed with single-layer wood board / wood square / log, or with decorative panels installed indoors. Some have poor thermal insulation performance, some have poor airtightness, and some have too thick walls. At present, wooden houses are mostly installed and assembled by on-site workers. Wooden columns or wooden squares are used as structural supports, and wooden boards or logs are used as wall enclosure structures. Some will cut grooves between the upper and lower logs and fill them with airtight flexible fillers to increase the airtightness effect. These common methods all use wood as the only insulation material, and do not use other more efficient insulation materials in combination to pursue better insulation effects. The thermal conductivity of wood is between 0.1-0.2. A large number of single increases in wood thickness, under the same effect, compared with professional insulation boards, such as EPs polystyrene boards and XPs extruded boards, their thermal conductivity is between 0.03-0.04, which will cause the wall to be too thick, occupying building space, and the cost is higher, and it is not easy to obtain large wood.

[0003] Through the above analysis, the problems and defects of the existing technology are: poor thermal insulation effect, occupying building space, difficult to obtain materials, and high cost. Summary of the invention

[0004] In view of the problems existing in the prior art, the utility model provides a double-sided sandwich insulation zero thermal bridge enclosure structure for a wooden house.

[0005] The utility model is implemented as follows: a double-sided sandwich insulation zero thermal bridge enclosure structure for a wooden house, comprising structural timber, which is erected between the wooden house wall, the wooden house roof and the wooden house floor; the structural timber of the wall and the roof is bounded on both inside and outside sides and fully covered with wooden boards with thermal insulation performance; the structural timber of the floor is provided with a steel plate on the outside, and the structural timber of the floor is bounded on the inside and outside sides and fully covered with wooden boards with thermal insulation performance; the space between the inner and outer wooden boards of the wall and the roof and the space between the indoor wooden board and the outer steel plate of the floor are filled with thermal insulation materials except for the position of the structural timber; a waterproof airtight film is bounded between the thermal insulation materials and the wooden boards on the inner and outer sides of the wall and the roof, between the thermal insulation material on the inside and outside sides of the floor and between the thermal insulation material and the wooden boards, and between the thermal insulation material on the outside and the steel plates.

[0006] Furthermore, the outer side of the structural wooden square of the ground is welded to the structural steel beam with a steel plate having a rust-proof effect.

[0007] Furthermore, the thermal insulation material includes XPs extruded board and EPs polystyrene board.

[0008] Furthermore, a high molecular weight polyurea waterproof and anti-corrosion coating is provided on the wooden boards outside the structural wood blocks of the wall and the roof, and an exterior wall paint decorative surface is provided on the high molecular weight polyurea waterproof and anti-corrosion coating.

[0009] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the utility model are as follows:

[0010] First, the utility model greatly enhances the thermal insulation performance of the external enclosure structure of the wooden house. Under the premise of the same thermal insulation effect, the thickness of the enclosure structure is reduced, the actual utilization space of the building is increased, and the airtightness effect of the wooden house is greatly improved; under the premise of the same thermal insulation effect, the difficulty of building the wooden house and the material cost are reduced; the combination of multiple materials greatly reduces the transmission capacity of sound and improves the sound insulation effect of the external enclosure of the wooden house.

[0011] During the research process, the 3.16x7 meter standard cabin was built with a sandwich design of 10 cm XPS extruded board and double-sided 3 cm pine wood board. The calculated insulation K value of the outer enclosure is about 0.35, compared with the calculated insulation K value of a single 16 cm pine wood enclosure structure of about 0.8. This design greatly improves the thermal insulation performance of the building itself without increasing the wall thickness.

[0012] The utility model greatly improves the overall thermal insulation performance of the house, reduces the energy consumption of heating and cooling, and greatly improves the room comfort index, including the reduction and balance of indoor temperature differences.

[0013] Third, as auxiliary evidence of the inventiveness of the claims of the utility model, it is also reflected in the following important aspects:

[0014] (1) The expected profit and commercial value of the technical solution of this utility model after transformation is RMB 5 million.

[0015] (2) The technical solution of the utility model fills the technical gaps in the industry at home and abroad: The utility model fills the partial or complete lack of thermal insulation design in domestic wooden house construction, the lack of airtightness design in wooden houses, and the lack of zero thermal bridge design in domestic box-type houses.

[0016] (3) The technical solution of the utility model solves the technical problems that people have been eager to solve but have never been able to solve: The utility model solves the technical problems of zero thermal bridge insulation design for wooden houses. It solves the reasonable matching and installation of wooden houses and insulation boards. It solves the simple construction technology of one-time forming of insulation and wooden house walls. It solves the problems of insulation cost, construction difficulty and long construction period.

[0017] (4) The technical solution of the utility model overcomes the technical prejudice: The technical solution of the utility model overcomes the functional goal of the structural layer to provide stable structural support, and the functional goal of the insulation layer to provide insulation effect, each of which performs its own function. The double-sided log design of the utility model has a good insulation effect, and the middle sandwich is filled with insulation board, forming a building material and thermal bridge with fast heat conduction both indoors and outdoors, realizing the structural layer as a thermal bridge-breaking insulation layer, and then cooperating with the main sandwich insulation layer to achieve the functional design of zero thermal bridge of the overall structure. The utility model also solves the technical prejudice of poor overall air tightness of wooden houses, and achieves the excellent result of air tightness N50 of the whole house less than 0.6 times / hour through research and enclosure structure design.

[0018] Third, the significant technical progress brought about by the wooden house double-sided sandwich insulation zero thermal bridge enclosure structure of the present invention is mainly reflected in the following aspects:

[0019] 1. Improved thermal insulation performance: By stapling thermal insulation wood boards on both sides of the structural wood and filling them with thermal insulation materials, the present invention significantly improves the thermal insulation performance of the log house. Compared with traditional single-layer or insufficiently insulated enclosures, the double-sided sandwich and zero thermal bridge design effectively reduce the loss of heat transferred through the enclosure, achieving a more efficient thermal insulation effect.

[0020] 2. Achieve zero thermal bridge effect: In traditional wooden house construction, thermal bridges are often formed at structural connection points, leading to heat loss and condensation problems. The present invention effectively avoids the thermal bridge phenomenon through the clever combination of structural wood and insulation materials, thereby reducing energy loss and improving indoor comfort.

[0021] 3. Improved waterproof and airtight performance: The design of binding waterproof and airtight membrane between the insulation materials and wooden boards on the walls, roofs and floors further enhances the waterproof and airtightness of the wooden house. This not only prevents moisture penetration and gas exchange, but also helps maintain the stability of the indoor environment, providing a safer and healthier living environment for the wooden house.

[0022] 4. Improved structural stability and durability: In the present invention, the steel plate is provided on the outside of the structural wood of the floor, which not only provides a solid bottom support, but also enhances the durability and corrosion resistance of the floor part. Combined with the polymer polyurea waterproof and anti-corrosion coating, the structural stability and durability of the entire wooden house are significantly improved.

[0023] 5. Convenience of construction and maintenance: The enclosure structure provided by the present invention is simple and clear in design, easy to construct and maintain later. The folding and unfolding of the protective baffle facilitates transportation and installation. At the same time, the modular design of the structure makes the later maintenance and replacement work more convenient.

[0024] The double-sided sandwich insulation zero thermal bridge enclosure structure of the log house of the present invention has brought significant technical progress in terms of thermal insulation performance, zero thermal bridge effect, waterproof airtightness, structural stability and maintenance convenience, and provides a more efficient, reliable and comfortable enclosure structure solution for modern log house construction.
