Description

Technical Field

[0001] The invention specifically relates to a modular energy-saving and heat-insulating steel-wood composite structure exterior protective wall, belonging to the technical field of building heat-insulating enclosure walls. Background Art

[0002] In the construction of traditional concrete frame structures, it is usually necessary to support the formwork first, and then cast the beams, slabs and columns into the main frame. Then, masonry blocks or strips are installed in the empty spaces between beams and columns to form an external wall system. Then, mortar plastering is used for leveling, and then insulation materials are applied to form an insulation layer. Finally, multiple layers of putty are applied or tiles are applied to form a decorative layer. It can be seen that this operation method requires multiple processes and all of them require on-site manual operation. It is not only inefficient but also difficult to ensure quality. It is easy to generate a large amount of construction waste and dust, which is not in line with the national policy of promoting green development. Summary of the invention

[0003] The purpose of the present invention is to address the deficiencies of the prior art and provide a modular energy-saving and heat-insulating steel-wood composite structure exterior wall, which has excellent thermal insulation, fire resistance and ductility properties and is highly modular.

[0005] The frame monomer is composed of a first U-shaped channel steel, a second U-shaped channel steel, a wooden column and a wooden strip;

[0006] The first U-shaped channel steel has first bolt holes at both ends, a first tapered hole, a first round hole and a second round hole in the middle section, the groove section of the first U-shaped channel steel is equal to the section of the wooden column, the inner surface of the first U-shaped channel steel is coated with epoxy resin, and the wooden column is connected and fixed by passing a self-tapping screw through the first tapered hole;

[0011] Furthermore, the outer section width of the first U-shaped channel steel is equal to the inner section width of the second U-shaped channel steel to ensure that the outer surface of the first U-shaped channel steel and the inner surface of the second U-shaped channel steel fit closely, thereby forming static friction on the contact surface.

[0012] Furthermore, a third bolt hole is opened at both ends of the wooden column, and the positions of the first bolt hole, the second tapered hole and the third bolt hole correspond to each other. The first U-shaped channel steel, the wooden column and the second U-shaped channel steel are connected by a screw rod passing through the second tapered hole, the first bolt hole and the third bolt hole in sequence. The two first U-shaped channel steels, the two wooden columns and the two second U-shaped channel steels are connected in the connecting area to form a frame unit.

[0013] Furthermore, the outer panel is assembled by OSB outer covering board, breathing paper, anti-corrosion water strip and outer decorative surface, the OSB outer covering board has four notches, and the breathing paper is adhered to the surface of the OSB outer covering board by special adhesive for breathing paper.

[0014] Furthermore, the anti-corrosion water-proof strips are laid on the breathing paper at a fixed interval and fixed to the OSB outer covering board by round nails. The outer decorative surface is fixed to the anti-corrosion water-proof strips by round nails and a ventilation cavity is formed between the breath paper.

[0019] The outer panel and the fireproof gypsum board are both connected to cover half the width of the first U-shaped channel steel on the connection side to reserve a certain space as the connection area between the outer wall monomers.

[0020] Furthermore, the long nail passes through the second sealing wood strip and the seventh circular hole in sequence to fix the second sealing wood strip on the frame unit, thereby completing the installation and splicing of two adjacent walls.
