Description

A bamboo-wood composite wall panel with round bamboo frame that is easy to install

Technical Field

The utility model relates to the technical field of bamboo-wood structure design and construction, and in particular to an easy-to-install round bamboo frame bamboo-wood composite wall panel which can be used for building wall panels and improves construction efficiency.

Background technique

In order to achieve the so-called dual carbon goals of carbon peak and carbon neutrality, the use of low-carbon and environmentally friendly bamboo and wood materials to build engineering structures in the field of civil engineering structures has been increasingly favored by the industry. In foreign industrialized countries, modern wood structures are a mainstream structural system and are widely used. In China, due to the reduction of forest resources, the country implemented strict logging restrictions at the end of the last century and closed mountains for forest cultivation, so the development of wood structures was relatively slow. In recent years, with the development of the economy, imported wood structures have gradually been recognized and accepted by domestic architectural and structural engineers. In addition, domestic fast-growing wood has also begun to mature and can be used. On the other hand, Chinese scholars and the industrial community are also committed to developing China's advantageous resource bamboo, producing a series of new bamboo structural materials such as glued bamboo, integrated materials, and reconstructed bamboo, and have carried out structural applications. It can be seen that bamboo and wood structures have broad application prospects at home and abroad, especially in the context of achieving dual carbon goals.

The direct use of round bamboo to build houses has a long history, but its geometric irregularity limits its promotion and application in modern architecture. However, compared with the glued bamboo that has been developed in recent years, the additional carbon emissions and energy consumption required for the production and construction of round bamboo structures are relatively low. Under the dual carbon goals, it is of great practical significance to explore how to reasonably design modern building structures to make the most of round bamboo.

Utility Model Content

The purpose of the utility model is to promote the application of round bamboo, a green and low-carbon material, in building structures, and at the same time solve the design and construction difficulties caused by its irregular shape by combining it with a small amount of engineering bamboo and wood standard materials, and provide an easy-to-install round bamboo frame bamboo-wood composite wall panel.

The technical solution adopted by the utility model is: an easy-to-install round bamboo frame bamboo-wood composite wall panel, comprising a round bamboo frame column unit, a frame and a wall panel veneer;

The round bamboo skeleton column unit is processed with a groove at the end of the skeleton column, and multiple round bamboo skeleton column units are fixed obliquely in the frame to form multiple inverted V-shaped frames, so as to increase the lateral surface resistance rigidity and strength of the wallboard. The round bamboo skeleton column unit is fastened by screws after being embedded in the frame through the groove;

The round bamboo skeleton column unit is provided with a wall panel decorative panel outside, and the cavity between the round bamboo skeleton column unit and the frame and the wall panel decorative panel can be filled with materials such as rock wool and polyurethane foaming agent to play the role of heat insulation and sound insulation.

The cross sections of the upper and lower transverse frames of the frame are T-shaped, with the raised edges facing the inside of the wallboard. During assembly, the grooves are clamped on the strip-shaped protrusions of the frame to play a positioning role.

Furthermore, the frame and the wall panel veneer are made of engineered bamboo or wooden standard materials, so that the appearance of the wall panel is standardized and suitable for factory processing and on-site disassembly and assembly.

Furthermore, the round bamboo skeleton column units can be bundled by means of flexible ropes arranged in the middle thereof to reduce the volume for easy storage and transportation, and during assembly and construction, the spacing of the skeletons can be controlled and adjusted.

Furthermore, the frame and the wall panel veneer are connected by metal nails and bolts, which is convenient for on-site assembly and disassembly.

Furthermore, the bamboo nodes inside the round bamboo skeleton column unit can be opened up and used as passages for electric wires or air conditioners.

Furthermore, the wall panel veneer can be made of fireproof decorative panels and veneers of various functional machine styles.

Beneficial effects: The utility model solves the structural problems caused by its geometric irregularity, and rationally and efficiently utilizes round bamboo in the walls or floor slabs of modern building structures, giving full play to its superior low-carbon characteristics and mechanical properties. The round bamboo skeleton columns can be arranged in an inverted V shape to increase the horizontal stiffness and strength within the wall panel surface. Before construction, the round bamboo can be bundled with a flexible connection configured in the middle to reduce the volume for easy storage and transportation. The composite wall panel adopts a peripheral frame and a facing material made of engineered bamboo or wooden standard materials, so that the appearance of the wall panel is standardized and suitable for factory processing and on-site assembly. All components of the skeleton are connected by metal nails and bolts, which are convenient for on-site assembly and disassembly when necessary.

Detailed ways

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

As shown in Fig. 1-6, an easy-to-install round bamboo frame bamboo-wood composite wall panel includes a round bamboo frame column unit 1, a frame 3 and a wall panel veneer 4;

As shown in FIG. 1 , a round bamboo skeleton column unit 1 of a certain length is taken and grooves 2 are opened at both ends thereof, and the shape and size of the grooves 2 match the raised section size of the upper and lower horizontal frames of the T-shaped section 5 shown in FIG. 2 .

As shown in FIG. 3 , the groove 2 at the end of the round bamboo frame is inserted into the protrusion of the T-shaped section 5 and fixed with screws. Pre-drilling or local reinforcement measures can be used to prevent the round bamboo from cracking.

As shown in FIG4 , in order to improve the in-plane lateral force stiffness and strength of the composite wall panel, the round bamboo frame column units 1 can be assembled into an inverted V-shaped frame 6. The frame assembled into a frame is fixed to the frame with bolts, and then the decorative panel is installed. The decorative panel is connected to the frame and the frame with screws. If disassembly is not considered, steel nails can also be used.

As shown in Figure 5, decorative panels are installed on both sides of the round bamboo frame bamboo-wood composite wall panel, and the cavity can be filled with rock wool, foaming materials, etc. to play a role in heat insulation and sound insulation.

When the bamboo-wood composite wallboard of the utility model needs to be disassembled, the wallboard veneer 4 is firstly put down, and then the four corners of the outer frame are loosened, and then the convex and concave joints between the bamboo frame and the upper and lower horizontal frames are loosened, so that all the bamboo frames and the frames can be separated. For the convenience of storage and transportation, the bamboo frame can be bundled with a flexible rope 7, as shown in FIG6 .

The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments.
