Description

Technical Field

[0001] The invention specifically relates to a modular energy-saving and heat-insulating exterior protective wall of a square steel tube filled with wood, and belongs to the technical field of building protective 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, and then lay blocks or install strips in the empty spaces between the beams and columns to form the outer wall system, and then apply mortar plastering and leveling, and then apply insulation materials to form an insulation layer, and finally apply multiple layers of putty or tile to form a decorative layer. It can be seen that this operation method requires multiple processes and all require on-site manual operation. It is not only inefficient and difficult to guarantee quality, but also prone to generate a large amount of construction waste and dust, which is not in line with the national policy of promoting green development.

[0003] Wood structures have attracted widespread attention in the construction industry due to their environmental friendliness and high modularity. As forest resources become increasingly scarce worldwide, fast-growing wood is widely planted due to its short growth cycle and high yield, but its low density, soft texture, and poor physical and mechanical strength limit its application in building load-bearing structural systems.

[0004] Cold-bent thin-walled steel is widely used in enclosure wall structures as a frame structure, but its cross-sectional width is large and it is prone to buckling failure when under pressure. The compressive bearing capacity and lateral resistance of the composite wall formed by connecting the panel and the light keel with self-tapping screws mainly depend on the mechanical properties of the self-tapping screws and the panel. Therefore, its application in buildings with large axial pressure on the top of the wall will be greatly limited.

[0005] Therefore, in response to the above problems, there is an urgent need to develop a multifunctional exterior enclosure wall that integrates enclosure, insulation and decoration, and has a highly modular nature. After mechanized production in the factory, it only needs simple installation when transported to the site, thereby reducing manual operations, improving construction efficiency and promoting the development of energy-saving buildings. Summary of the invention

[0006] The purpose of the present invention is to provide a modular energy-saving and heat-insulating exterior protective wall of square steel pipes filled with wood in view of the shortcomings of the prior art.

[0012] Preferably, the outer panel and the fireproof gypsum board are both connected to cover half the width of the first cold-bent thin-walled square steel pipe on the connection side, so as to reserve a certain space as a connection area between two frame monomers.

[0013] Preferably, the frame monomer, the outer panel and the fireproof gypsum board are filled with thermal insulation material to form the thermal insulation layer.

[0014] The beneficial effects of the present invention are as follows: the components of the frame unit, the fireproof gypsum board, the outer panel and the insulation layer can be assembled in advance in the factory, and then the unit can be transported to the site for connection and installation through the connecting steel plates, which is convenient for on-site construction.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-Figure 12 A modular energy-saving and heat-insulating steel-wood composite structure exterior protective wall includes a frame unit 1, an outer panel 2, a fireproof gypsum board 3, an insulation layer 4, a connecting steel plate 5 and a sealing wooden strip 6. The frame unit 1 includes a first cold-bent thin-walled square steel pipe 11, a first wooden column 12, a second cold-bent thin-walled square steel pipe 13, a wooden beam 14, a rectangular cold-bent thin-walled steel pipe 15, a second wooden column 16 and an angle steel 17.

The inner surface of the first cold-bent thin-walled square steel tube 11 is coated with epoxy resin adhesive, and the self-tapping screw 7 passes through the first conical hole 111 to connect and fix the first wooden column 12.

[0048] The second cold-bent thin-walled square steel tube 13 is provided with a second conical hole 131 , a fifth circular hole 132 and a sixth circular hole 133 .

[0050] The epoxy resin adhesive makes the first cold-bent thin-walled square steel pipe 11, the second cold-bent thin-walled square steel pipe 13 and the rectangular cold-bent thin-walled steel pipe 15 have good bonding properties, anti-corrosion properties and mechanical properties. The epoxy resin adhesive can also fill and bridge some unevenness or minor defects that may exist on the inner surfaces of the first cold-bent thin-walled square steel pipe 11 and the second cold-bent thin-walled square steel pipe 13, thereby enhancing the bonding strength between the coating and the channel steel. In addition, the epoxy resin adhesive can form a dense oxide film on the surface of the first cold-bent thin-walled square steel pipe 11 and the second cold-bent thin-walled square steel pipe 13, thereby effectively slowing down the corrosion rate and increasing the service life.

[0051] See also Figure 3 and 13 As shown, the two first cold-bent thin-walled square steel tubes 11 and the two second cold-bent thin-walled square steel tubes 13 are welded in the connection area, the two ends of the rectangular cold-bent thin-walled steel tube 15 are welded and fixed to the second cold-bent thin-walled steel tubes, the angle steel 17 has a fourth tapered hole 171, and the angle steel 17 is welded with a stiffening rib 172 to improve the lateral rigidity of the frame monomer 1.

[0052] See also Figure 3 , Figure 5 , Fig. 9 , Fig.13 In order to install the angle steel 17 at the corner of the connection area between the beam and the side column, the self-tapping screw 7 passes through the fourth tapered hole 171 and the second circular hole 113 in the connection area of ​​the side column end in sequence and is then anchored into the fast-growing wood side column, thereby fixing one end of the angle steel 17 on the first cold-bent thin-walled square steel tube 11, and the self-tapping screw 7 passes through the fourth tapered hole 171 and the sixth circular hole 133 in the connection area of ​​the beam end in sequence and is then anchored into the wooden crossbeam 14, thereby fixing the other end of the angle steel 17 on the second cold-bent thin-walled square steel tube 13.

[0053] See also Figure 3 , Fig. 9 , Fig.11 , Fig.13In order to install the angle steel 17 at the corner of the connection area between the beam and the middle column, the self-tapping screw 7 passes through the fourth tapered hole 171 and the eighth circular hole 153 in the connection area at the end of the middle column in sequence and then is anchored into the second wooden column 16, thereby fixing one end of the angle steel 17 on the rectangular cold-bent thin-walled steel pipe 15, and the self-tapping screw 7 passes through the fourth tapered hole 171 and the sixth circular hole 133 in the middle connection area of ​​the beam in sequence and then is anchored into the wooden crossbeam 14, thereby fixing the other end of the angle steel 17 on the second cold-bent thin-walled square steel pipe 13.

[0054] See also Figure 3 , see Figure 2 The breathing paper 22 is adhered to the OSB covering panel 21 by a special adhesive for breathing paper, the anti-corrosion water strips 23 are laid on the breathing paper 22 at a fixed interval and fixed to the OSB covering panel 21 by long nails 8, and the outer decorative surface 25 is fixed to the anti-corrosion water strips 23 by long nails 8, and a ventilation cavity is formed between the breathing paper 22 and the breathing paper 22. By utilizing the natural convection of air, hot air will rise due to its low density, and cold air will fall. Through this ventilation cavity, air can flow in it, thereby taking away moisture and heat in the cavity. The OSB covering panel 21, the breathing paper 22, the anti-corrosion water strips 23 and the outer decorative surface 25 are assembled to form the outer panel 2. The OSB covering panel 6 is a board formed by using an oriented structural strand board as the base material, and a layer of decorative material or functional material is covered on its surface through veneer treatment or other processes. It has the advantages of high strength and good environmental performance.

[0055] See also Figure 3 , Figure 4 , Figure 7 , Fig.10 The fireproof gypsum board 3 is provided with a ninth circular hole 31, and the long nail 8 passes through the ninth circular hole 31 and the first circular hole 112 in the side column connection area, passes through the ninth circular hole 31 and the fifth circular hole 132 in the beam connection area, and passes through the ninth circular hole 31 and the seventh circular hole 152 in the middle column connection area to connect and fix the fireproof gypsum board 3 to the inner side of the frame monomer 1.

The insulation material here can be one of rock wool, glass wool, polyurethane foam, and polystyrene foam. These materials have low thermal conductivity, can effectively reduce heat conduction, and have a good insulation effect, thereby assembling an outer wall unit 10.

[0058] See also Figure 1 The outer panel 2 and the fireproof gypsum board 3 are connected to cover half the width of the first cold-bent thin-walled square steel tube 11 to reserve a certain space as the connection area between the outer protective wall monomers 10.

[0059] See also Figure 1 , Figure 4 , Fig.14 The connecting steel plate 5 is provided with a fifth tapered hole 51, and the fifth tapered hole 51 corresponds to the third circular hole 114 in position. The self-tapping screw 7 passes through the fifth tapered hole 51 and the third circular hole 114 in sequence to connect and fix the connecting steel plate 5 to the connecting areas on the inner and outer sides of the two adjacent frame monomers 1, thereby completing the installation and splicing of the two adjacent outer protective wall monomers 10.
