Description

A two-way skeleton structure wall

technical field

The utility model relates to a wall structure, in particular to a wall with a two-way skeleton structure mainly used as an exterior wall of a wooden structure building.

Background technique

In recent years, wooden structure residential buildings have developed rapidly in my country, and its unique architectural style and performance advantages have been affirmed by more and more consumers.

The walls of traditional wood structure buildings, especially the exterior walls, the skeleton structure mainly includes a plurality of wall studs arranged in parallel at intervals. The wall studs generally use sawn timber with a cross-sectional size of 40mm×90mm or 40mm×140mm. In the wall of a wooden structure building, each wall stud is arranged vertically, and the upper and lower ends of the wall stud are usually provided with an upper top plate and a lower bottom plate to connect and fix each wall stud to form a skeleton frame of the wall; in the skeleton structure The two sides are usually directly covered with wall panels (such as wooden structural panels and gypsum boards) to form a wall; the cavity formed by the wall panels and wall studs in the wall is often filled with thermal insulation materials, such as glass wool etc.

The wall of the above structure has the following problems: First, the lateral strength and rigidity of the wall are poor, and generally cannot be used as a shear wall; secondly, the wall of this structure is extremely easy to form resonance in places where noise often occurs, making the sound The increase of the transmission volume leads to poor sound insulation performance of the wall, which is not suitable for multi-family residence or wooden structure buildings with special functions, especially in China with high population density and dense living, the resonance and sound insulation effect caused by the wall are poor The problem will be particularly prominent; moreover, in the wall of this structure, the independent structure between the cavity formed by the wall panel and the wall stud causes the air to be unable to circulate, and the line is also inconvenient to pass through; in addition, in the event of a fire, there will be a direct crisis Load bearing studs.

On the other hand, with the rapid development of wood-structure residential buildings in my country, the demand for structural wood products such as dimension lumber and laminated veneer lumber for wood-structure buildings is increasing year by year. However, due to the lack of timber resources in China, the natural forest protection project has been launched many years ago, and the application of large-diameter timber is limited. Therefore, the use of artificial fast-growing forest timber is an effective way to alleviate the shortage of timber in my country. However, during the processing and utilization of plantation timber, it was found that the standard timber required by the existing timber structure design specifications, especially sawn timber with conventional cross-sectional dimensions of 40mm×90mm and 40mm×140mm (such as the wall studs used in the above-mentioned wall structure ), the yield rate is only about 30% to 40%. In order to obtain studs of the required size, large diameter timbers are usually used.

In view of this, it is indeed necessary to improve the wall structure of traditional wooden buildings.
