Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of outer wall aluminium square tube, applied in engineering construction field. BACKGROUND

[0002] The existing outer wall aluminium square tube 1' is hollow strip long rectangular tube, is usually installed on outer wall 6' for decoration (such as Figure 1 As shown). When installing, first embed iron plate 5' in outer wall and let iron plate part expose outer wall surface, main keel 7' (usually 70*50*5 steel pipe) extends along longitudinal direction and is arranged on the lateral wall of outer wall along transverse direction parallel interval, and is fixed by welding on the exposed surface of the iron plate. Then, the outer wall is daubed and the outer wall decorative layer (usually real stone paint) is daubed. Corner code 9' (4MM thick steel plate connecting piece) is welded on the upper and lower lateral wall of main keel, and outer wall aluminium square tube extends along transverse direction and is arranged along longitudinal direction parallel interval, and installation hole is formed on aluminium square tube, and bolt 8' (usually 8*25) is used to fix aluminium square tube on corner code by passing through installation hole. The existing outer wall aluminium square tube has the following shortcomings when installing: 1. corner code is exposed, because the space behind the curtain wall formed by outer wall aluminium square tube is limited, and the welding seam cannot be polished, which is not beautiful; 2. welding fume and spark will pollute the paint layer behind the curtain wall.

[0003] Therefore, it is urgent to provide an outer wall aluminium square tube with simple structure, convenient installation, no need to use corner code, good appearance, large rigidity and not easy to deform. INVENTION CONTENTS

The installation of the outer wall aluminum square tube does not need to use angle code, greatly simplifies the process, shortens the construction time, and avoids the problems of exposed angle code and the need to polish the welding seam. Considering the influence of outdoor wind pressure, the end plate thickness of the adjustable thick square tube body of the outer wall aluminum square tube can be adjusted, or a gasket can be used for reinforcement and fastening. The outer wall aluminum square tube has the functions of waterproofing and rust prevention when used outdoors.

[0008] The installation method of the outer wall aluminum square tube:

[0009] 1. First, embed the iron plate 5 in the outer wall 6 and let the iron plate partially protrude from the outer wall surface;

[0010] 2. The main keel 7 is arranged horizontally and parallel on the side wall of the outer wall, and is fixed on the exposed surface of the iron plate by welding;

[0011] 3. Plaster the outer wall and apply a decorative layer to the outer wall;

[0012] 4. Open the cover plate, and use a pipe-in-pipe sleeve to pass the self-tapping screw 8 through the first mounting hole to fix the square tube body on the main keel;

[0013] 5. Cover the cover plate on the side opening of the square tube body, and the installation of the outer wall aluminum square tube is completed.

[0014] The side plate one and the side plate two are provided with protrusions extending towards the opposite side plate on the side close to the opening, and the positions of the two protrusions correspond to each other. The cover plate is movably connected with the square tube body through the two protrusions.

[0015] The protrusions facilitate the movable covering of the cover plate.

[0016] The cover plate comprises a cover plate body and two clamping strips connected on the same side of the cover plate body and extending into the inner cavity of the square tube body. The distance between the outer side walls of the two clamping strips corresponds to the distance between the free end portions of the two protrusions. The free end portion of each clamping strip is provided with a clamping tooth extending towards the direction of the protrusion on the same side of the clamping strip. The distance between the clamping tooth and the cover plate body corresponds to the thickness of the protrusion. The width of the cover plate body corresponds to the distance between the side plate one and the side plate two.

[0017] The clamping strips and clamping teeth of the cover plate make the connection of the cover plate more rapid and firm.

[0018] The outer wall aluminum square tube further comprises a middle rib plate, which is arranged in the inner cavity of the square tube body and connected to the opposite surfaces of the first side plate and the second side plate respectively and parallel to the third side plate; and each group of mounting holes further comprises a second mounting hole arranged on the middle rib plate, which corresponds to the first mounting hole in position and has a larger hole diameter than the first mounting hole.

[0019] The arrangement of the middle rib plate can increase the overall rigidity of the outer wall aluminum square tube and reduce the deformation probability thereof.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] 1) The outer wall aluminum square tube of the utility model adopts a square tube body with an open side, a cover plate for movably closing the opening, and a first mounting hole arranged on the end plate, so that the square tube body can be conveniently fixed on the main keel, and the utility model has the advantages of simple structure, convenient installation, no need of using an angle code, and good aesthetic appearance;

[0022] 2) The arrangement of the convex strips facilitates the movable closing of the cover plate;

[0023] 3) The arrangement of the clamping strips and the clamping teeth of the cover plate makes the connection of the cover plate faster and more secure;

[0024] 4) The arrangement of the middle rib plate can increase the overall rigidity of the outer wall aluminum square tube and reduce the deformation probability thereof. BRIEF DESCRIPTION OF DRAWINGS
