Description

A steel-wood-bamboo composite board

technical field

The invention belongs to the field of building structures in civil engineering, and specifically refers to a steel-wood-bamboo composite board that can meet many functions such as floor slabs, filling walls and bridge decks.

Background technique

With the increasingly prominent environmental problems, the public's awareness of environmental protection is improving. In order to reduce the dependence on high energy consumption and high pollution building materials such as clay bricks, steel and cement, energy-saving, environmentally friendly and renewable green building materials are increasingly favored by people. As a renewable resource, wood has the advantages of light weight and beautiful appearance. It should be vigorously promoted. However, because my country's wood resources are not abundant, most of the popular wooden building materials in the market are imported products, so its development has been restricted.

Similar to wood, bamboo is a renewable resource, but compared with wood, bamboo has the advantages of shorter growth cycle, greater strength, better toughness, and richer resources. Therefore, the country vigorously advocates "replacing wood with bamboo". At present, the common bamboo-wood composite materials are mostly used for decorative flooring and furniture manufacturing, which have the disadvantages of insufficient bearing capacity and complicated processing. How to make better use of the respective advantages of bamboo and wood is a difficult problem in current applications.

People's living standards are improving, and their requirements for housing are also increasing. Traditional walls are mostly masonry walls or reinforced concrete walls, which have the disadvantages of heavy weight, high pollution, and complicated construction. Although many new partition walls with convenient construction and light weight have been applied at present, there are also some shortcomings, such as: (1) The scope of use is limited. Most of the new partition walls are only used for the function of partition walls, and cannot meet the various requirements for use of interior walls, exterior walls, bridge decks, floor slabs, etc.; (2) The materials are not environmentally friendly. For example, the core material of the new partition wall of plastic board is plastic, which cannot be degraded naturally and is harmful to the environment; (3) sound insulation and heat insulation effect are poor. New types of partition walls such as steel wire frame foam board partition walls use foam materials, which have the hidden danger of poor fire performance.

Contents of the invention

The technical problem to be solved by the present invention is: aiming at the disadvantages of the existing boards such as single use, heavy weight, and non-environmental protection, the present invention provides a low self-weight, environmentally friendly materials, low cost, simple construction, and can simultaneously meet the needs of floors, partitions, etc. Steel-wood-bamboo composite panels required for many applications such as walls, bridge decks or exterior walls.

In order to solve the above-mentioned technical problems, the solution proposed by the present invention is: a steel-wood-bamboo composite board, which successively includes a panel, a steel wire mesh, an internal frame (edge sealing board, an inner skeleton, an outer skeleton), a steel wire mesh And the panel is characterized in that the inner frame and the outer frame are connected to the edge banding board through steel connectors, the steel wire mesh is laid on the inner frame, the panel is laid on the steel mesh, and nails are used for reinforcement between the panel and the inner frame.

The basic principle of the present invention is as follows: the panel is selected from industrially processed bamboo plywood, which can be bamboo curtain plywood or bamboo mat bamboo curtain plywood, and is placed on the outermost side of the panel to bear the stress in all directions; the steel wire mesh is placed between the panels. The load-bearing performance of the whole board is improved; the edge board, the inner skeleton and the outer skeleton are made of wood, and the density of the wood is low to ensure the weight of the board is small; the steel connectors and screws connect the parts of the board into a whole and play a role of reinforcement ; The steel-wood-bamboo composite board retains the natural texture of the bamboo-wood material, which is beautiful and generous, and does not need to be redecorated when it is put into use.

The edge banding board, the inner frame and the outer frame are made of wood, and the moisture content is not more than 12%.

The edge banding board is perpendicular to the inner skeleton and the outer skeleton, and has the same cross-sectional size.

The steel wire mesh is symmetrically arranged on both sides of the edge banding board, the inner frame and the outer frame. The steel wire mesh is woven with fine steel wire or galvanized iron wire. The mesh size is not more than 10mm×10mm, and the diameter is not less than 1mm.

The panels are symmetrically arranged on the outside of the steel-wood-bamboo composite board and connected by nails, and the direction along the grain of the panel is parallel to the length direction of the edge banding board.

The panel adopts 3 to 5-year-old moso bamboo as a raw material, and is a bamboo plywood processed by processes such as sawing, cooking, carbonization, drying, slice selection, and gluing of blanks.

The surface of the steel connector is made of Q235 steel, and the surface of the steel connector is galvanized. One end of the steel connector is fixed on the edge plate, and the other end is fixed on the inner frame or outer frame and connected by screws.

The cavity formed by the edge banding board, the inner skeleton and the outer skeleton is filled with thermal insulation cotton, which is in the shape of block or floc.

Compared with the prior art, the present invention has the following beneficial effects:

(1) The material is environmentally friendly. Bamboo and wood materials are renewable materials, and their production process is pollution-free, which is in line with the concept of sustainable development. Bamboo has the advantages of short growth cycle, fast growth, and rich resources. Applying bamboo to the construction field can reduce domestic dependence on high-pollution and high-energy-consuming materials such as concrete and steel, and is conducive to the improvement of my country's environment.

(2) High production efficiency. Traditional cast-in-place floor slabs or partition walls require on-site construction, which is slow and inefficient. The present invention can be used for large-scale standardized construction in factories and is almost not affected by weather conditions. It is more reliable in quality. After prefabrication, it can be assembled on site. Greatly improve construction efficiency.

(3) Lightweight and high strength. Compared with masonry materials and reinforced concrete materials, the invention greatly reduces the dead weight; compared with single wood or bamboo, the invention combines steel, wood and bamboo to have better mechanical properties.

(4) Beautiful and generous. The texture of the bamboo and wood material itself is beautiful, and after a certain processing, the surface is smooth and the texture is comfortable. Modern families often use wooden floor or bamboo floor to decorate the ground. When bamboo and wood materials are directly used as floor or wall, it is not only beautiful and comfortable, but also saves considerable decoration costs.

(5) Good durability. The panel of the present invention is generally made of 3 to 5-year-old large-diameter moso bamboo as a raw material, and is processed by processes such as sawing, cooking, carbonization, drying, selection, and gluing of the blanks, and has the functions of moisture-proof, anti-corrosion, mildew-proof, and moth-proof. And aging performance and other advantages.

(6) Wide range of uses. According to actual needs, a steel-bamboo-wood composite board can be designed in corresponding dimensions and improved in moisture-proof and anti-corrosion properties, which can meet the requirements of many functions such as floor slabs, partition walls, roof slabs, and bridge slabs.
