Description

A CLBT thick slab structure with interlaced glued bamboo and wood that can be used as walls and floors

technical field

The invention belongs to the technical field of civil construction engineering, and in particular relates to a cross-glued bamboo-wood combined thick plate member.

Background technique

Compared with traditional steel, brick-concrete, and reinforced concrete structures, wooden structures have the advantages of less building energy consumption, good seismic performance, simple construction, energy saving and heat preservation, and environmental friendliness. However, due to large-scale deforestation in the last century, my country's forest resources are almost scarce, so the country has introduced strict forest protection measures. At the same time, afforestation is actively carried out, especially a lot of fast-growing forests have been added, and these fast-growing forests have reached or are close to the harvesting period. my country has the most abundant bamboo forest resources in the world. The physical and mechanical properties of bamboo are similar to that of wood, and it has the advantages of light weight, low price, good toughness, wide source of materials, especially short maturity period, etc. It is a more green and environmentally friendly material. At present, glued wood and glued bamboo are used in civil structures, especially in foreign industrialized countries, where glued wood structures are widely used. The development of structural components made of wood and bamboo and its application in civil structures can make full use of the respective advantages of bamboo and wood, and provide engineering circles with various energy-saving, environmentally friendly, beautiful forms, good mechanical properties, light weight, and practicality. Strong structural members.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a bamboo-wood composite structural thick plate member with energy saving, environmental protection, beautiful appearance, excellent performance, light weight and strong practicability, which can be used to build walls and floor structure.

The technical scheme adopted in the present invention is: a kind of cross-glued bamboo-wood composite CLBT thick board structure that can be used as a wall and a floor slab, CLBT (Cross Laminated Bamboo and Timber), including bamboo-wood composite thick board components, made of multi-layer bamboo and wood It is staggered and glued. The main fiber directions of bamboo and wood are parallel to each other or staggered vertically. and fixed by self-tapping bolts;

The present invention is different from the existing bamboo-wood composite boards that are mainly used as floors, furniture or container and carriage floors, and has a thickness of about 70 mm or more, which reaches the thickness that can be directly used as building walls and floor slabs.

A plurality of bamboo and wood composite thick plate components are connected in parallel to form a whole wall or floor;

The vertical butt joint between two thick bamboo and wood composite components forms the corner of the wall or the corner of the floor and the wall;

Both sides of a vertical bamboo-wood composite plank member are docked with two parallel bamboo-wood composite plank members at the same time. The convex and concave edges of the parallel bamboo-wood composite plank members are provided with pre-drilled holes. Embedded bolts are provided on the convex and concave edges of the components, and the embedded bolts are inserted into pre-drilled holes and fixed by glue to form mutually perpendicular walls or floors lapped with the lower wall.

Preferably, an interlayer is provided inside the bamboo-wood composite plank member.

Preferably, the bamboo material is made of bamboo sheets, boards and strips, with a thickness of 10-30 mm.

Preferably, the wood is cut and surface-smoothed wooden boards and strips, with a thickness of about 30 mm. Wood made from fast-growing tree species can be selected to match the fast-growing characteristics of bamboo to achieve a more environmentally friendly effect.

The invention adopts the bamboo and wood combined thick board member which is formed by interlacing and gluing bamboo and wood, which can be used as building walls and floors. Bamboo and wood chips, boards or strips are selected and arranged in layers staggered or alternately according to the design. The main fiber directions of bamboo and wood can be arranged at a certain angle or in parallel according to the design requirements, and then a certain pressure is applied at room temperature for gluing. A thick plate with the required thickness, generally greater than 70mm. The edges of the thick boards are provided with special protrusions and dislocations. When the thick boards are assembled into a wall or floor, the protrusions and dislocations of the edges of the boards and the boards are just in line with the joints and can be connected and fixed by self-tapping bolts or nails to form a whole piece of wall or floor. The plates can be spliced at an angle and fixed by self-tapping bolts and embedded bolts. Because the thick board of the present invention has a relatively thick thickness (generally greater than 70 mm), it has certain requirements for heat preservation and sound insulation, and can be directly assembled into a wall or a floor. However, if there is a need for further thermal insulation or sound insulation, the bamboo-wood composite thick board can be processed into half pieces along the thickness direction. When making the wall or floor of a building, a hollow or interlayer is left in the middle to assemble a wall or floor of complete thickness.

Beneficial effects: the invention fully utilizes the appearance form and material properties of bamboo and wood, has the advantages of beautiful form, controllable heat preservation and mechanical properties, and strong practicability, and can provide a new type of component for civil engineering and architectural design.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the bamboo-wood composite thick plate member is formed by interlacing and gluing multiple layers of bamboo 1 and wood 2, and the bamboo 1 and wood 2 can be interchanged according to design requirements. For walls and one-way floors that mainly bear gravity, the main fiber directions of bamboo 1 and wood 2 should generally be arranged parallel to the axial direction.

As shown in Figure 2, it is an example of assembling a whole body of wall or floor slab from bamboo-wood glued thick boards processed according to a certain module size. After the convex and concave edges 3 are aligned and occluded, the bamboo and wood composite thick plate components are fixed with self-tapping bolts 4 to form a whole wall or floor.

As shown in Figure 3, it is an example of assembling walls or floors at the corners of bamboo-wood glued thick boards processed according to a certain module size. The bamboo-wood combined thick plate member is fixed with self-tapping bolts 4 to form the corner of the wall or the corner of the floor and the wall after the convex and concave edges 3 are aligned and occluded according to the angle.

As shown in Figure 4, it is an example of cross-splicing bamboo-wood glued thick boards processed according to a certain module size to form mutually perpendicular walls or floor slabs and lower walls. When the bamboo-wood composite thick plate member is assembled, the pre-drilled holes 6 of the thick plates on both sides are aligned with the embedded bolts 5, and then the convex and concave edges 3 of the thick plates are spliced, and then fixed with self-tapping bolts 4 . After assembling, glue can be injected into the pre-drilled holes 6 to fix the embedded bolts 5 .

As shown in Figure 5, it is a schematic diagram of half-sheets of interlaced glued bamboo and wood planks pressed along the thickness direction. According to design requirements, as shown in Figure 6, an interlayer 7 with a certain thickness can be arranged according to the design and then assembled into a whole.
