Modular wood house wall structure and construction method thereof

Abstract

The invention discloses a modular wood house wall structure and a construction method thereof. The wall structure comprises two-side wood plate layers, covering face keel frames, a heat insulating layer, a gypsum plate and fasteners; the two-side wood plate layers comprise the inner side wood plate layer and the outer side wood plate layer which are composed of standard wood plates and wood plate connection members; grooves are formed in the standard wood plates in advance; the wood plate connection members are I-shaped stainless steel members; and tenons on the wood plate connection members are connected with the wood grooves of the standard wood plates in a sleeving mode. Connection of the standard wood plates can be firmer in the mode of matching with elastic materials on the wood plate connection members, the wood plate connection members are further provided with heat insulating materials and structures capable of preventing heat bridges, and the heat insulating layer is filled with a non-woven bag filled with sawdust, so that the wall heat transfer coefficient is greatly reduced, and engineering waste reuse is achieved. The modular wood house wall structure and the construction method thereof have the advantages of wood material saving, heat preservation and heat insulation, waste reuse, connection fastening, convenient mounting and the like and have excellent popularization value in the field of assembly construction.

Description

technical field [0001] The invention relates to a wall structure of a wooden house, which belongs to the field of wooden structure walls for building wall modular production and on-site assembly. [0002] technical background [0003] As the most important part of a building, the building wall plays a decisive role in the indoor thermal and humid environment and acoustic environment of the entire building. Relevant studies have shown that the building energy consumption caused by the heat loss of the external wall accounts for 30% of the energy consumption of the entire building. Therefore, it is necessary to pay attention to reducing the heat transfer coefficient of the wall while paying attention to the structural mechanical properties of the building wall. Wood is one of the earliest building materials used by humans, and it is also the most renewable building material among the four major materials (steel, cement, wood and plastic) that can be reused and recycled many tim...

Problems solved by technology

After a patent search, it was found that the Chinese patent publication number CNIO3924724A, the name of the invention patent is: a wooden house wall module and a wooden house wall, the wooden wall uses two parallel wooden boards as the main body, and the two wooden boards pass through tenon and groove The position is fixed, and there is an air cavity in the middle of the wooden wall, which is convenient for assembly and saves wood at the same time. However, if the wall area using this technology is large, it must be assembled into large wooden boards with plywood, and plywood is generally glued together. It is bonded, so the wall is prone to deformation and cracks after long-term use or in a high-temperature and high-humidity climate environment

In addition, the Chinese patent authorization announcement number: CN201649353U, and the utility model patent name is: seamless log stacking wood wall. This technology achieves the purpose of sealing by opening grooves on the log and connecting the protrusions up and down. Adhesives such as glue still need to be used to seal the gap between two logs in the upper application, and the airtightness is difficult to be guaranteed during long-term use, and the thickness and strength of the wall depend entirely on the cross-section of the logs Diameter, sometimes difficult to meet certain wooden house walls with specific strength requirements

[0005] First of all, the wooden wall with double-layer structure can achieve the purpose of saving wood and reducing the heat transfer coefficient of the wall under the condition of satisfying the strength of the wall; secondly, because the idea of ​​modular construction is to uniformly produce standardized building products in the factory , and then transported to the construction site for overall installation. For wooden walls, a large amount of waste sawdust will inevitably be produced in the process of processing raw materials into planks of required size. How to deal with the large amount of sawdust remaining in the project is a problem. Important issue; third, for the construction of large-area wooden walls, a number of small-area or medium-area wooden boards must be spliced ​​together by a certain method, and it is difficult to achieve the purpose of long-term durability of the wall by directly using glue or fasteners
