Description

Light wood structure wall

Technical Field

The utility model relates to a light wood structure wall, and belongs to the technical field of fireproof design of wood structure walls.

Background

Concrete, steel structures and wood structures are the major building structure forms in the world today. The concrete structure has high strength and excellent fire resistance, so the concrete structure is widely applied in China, but has the defects of great self weight, long construction period, environmental pollution and the like; although the steel structure has the characteristics of large strength-weight ratio, good plasticity and toughness and the like, the steel structure has the defects of no fire resistance and easy corrosion; the wood structure has the advantages of reproducibility, environmental friendliness, excellent anti-seismic performance and the like, but the wood belongs to combustible materials, and the fire resistance requirement of the wood is high in use. In response to the aspect of fire resistance, a heavy wood structure of a large cross section can effectively protect interior wood through a carbonized layer formed upon combustion; for small section, lightweight wood structures, non-combustible sheathing and construction measures are employed to improve fire resistance. Although there are many studies on fire resistance of lightweight wood structures, they are relatively few studies on the properties of panelized materials, and relatively few studies on construction and structure.

The fire resistance of the light wood structure wall body serving as a main bearing component of the light wood structure is very important. The light wood structure wall is a combined wall formed by assembling a bone column, a top beam plate and a bottom beam plate into a wood frame through nail connection, filling rock wool in a cavity of the frame and matching covering plates on two sides. Plasterboards are the most widely used fire resistant panels at present, with standard dimensions of 2440mm x 1220 mm. When the gypsum board is laid along the longitudinal direction of a wall, a gap of 2-3mm is formed between two standard-sized gypsum boards. A large body of literature indicates: when a fire disaster occurs, heat flow enters the wall body preferentially from the gaps, so that the bone columns at the gaps are combusted, the fire is leaped up at the gaps of the wall body with the back fire surface, the wall body fails, but the bone columns at other parts still keep relatively complete, and the wall body cannot fully exert the performance. It is conventional to apply plaster putty in the gap, but there is a very limited increase in the fire endurance of the wall.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a light wood structure wall body which can effectively enhance the fireproof performance of gaps among gypsum boards.

In order to solve the problems, the technical scheme adopted by the utility model is as follows:

The fireproof covering panel 1 is connected with the frame through twist nails 3. Rock wool 4 with heat preservation and insulation functions is filled in the cavity of the frame 2, and combined wood-bone columns 9 are fixedly connected between the fireproof covering panels 1 on the two sides. Referring to fig. 4 and 5, the combined wood-bone column 9 comprises two specification materials 7 and a gypsum strip 6 fixedly connected between the two specification materials, wherein the gypsum strip 6 is perpendicular to the fireproof covering panels 1, and the position of the gypsum strip 6 is opposite to the position of the gap 5 between the adjacent fireproof covering panels 1. The manufacturing process of the combined wood-bone column 9 is as follows: cutting into specification material 7 with required thickness along the thickness direction by using a planer; placing a gypsum strip 6 on the cut specification material 7, and uniformly brushing polyvinyl acetate emulsion between the gypsum strip 6 and the specification material 7; similarly, a standard material 7 is placed on the gypsum strip 6, the standard material 7 and the gypsum strip 6 are connected through a self-tapping screw 8 to form a combined wood-bone column 9, and the combined wood-bone column 9 is maintained for one week in a normal-temperature environment.

Compared with the figures 2 and 3, the wood-bone column 2 at the gap 5 in the prior art is replaced by the combined wood-bone column 9, the gypsum strip 6 is opposite to the gap 5, and the twist nails 3 at two sides of the gap are nailed on the specification material 7. When the fireproof covering panel is used, due to the gypsum strips 6 in the gaps 5, when a fire disaster occurs, the heat flow can be well prevented from impacting the gaps 5 between the fireproof covering panels, so that the influence of the fire disaster on the combined wood-bone columns 9 in the gaps is delayed, and the overall fireproof performance of the wall body is improved.
