Description

Technical Field

[0001] The invention relates to the technical field of building metal composite plate curtain wall engineering, in particular to a metal composite plate external sunshade curtain box structure and a construction process thereof. Background Art

[0002] Public buildings and industrial buildings need to install external sunshades on the outside of the windows due to the requirements of building functions and energy-saving design, so as to control the intensity of indoor sunlight and reduce the indoor air-conditioning load. If the exterior wall decoration material is a metal composite panel curtain wall, for the sake of aesthetics, the sunshade box and the metal composite panel curtain wall are generally designed as a whole, that is, the metal composite panel is folded into the sunshade box to achieve a unified appearance of the curtain wall and the sunshade box.

[0003] According to the provisions of the General Code for Civil Buildings, the area contained by the outer edge of the curtain wall panel must be included in the building area of ​​a building. Therefore, from an economic point of view, the distance between the curtain wall panel and the outer wall of the main structure should be designed to be as small as possible to reduce the unusable building area of ​​the building. Therefore, it is generally not possible to solve the problem of insufficient installation space for the sunshade box by increasing the distance between the curtain wall panel and the outer wall of the main structure. Instead, special measures can only be taken within the limited space. The distance between the curtain wall panel and the outer wall of the main structure is generally designed to be 200mm-250mm. To complete the construction of the curtain wall panel, sunshade box, and exterior wall insulation within this width, the space is very tight. According to traditional practices, the cross-sectional width of the square steel keel of the sunshade box cannot exceed 30mm. The keel of this specification cannot play a reinforcing role, resulting in insufficient structural strength of the sunshade box, insufficient installation flatness, and insufficient wind pressure resistance. In addition, the keel is too small and the metal composite panel is not easy to bend. Since the sunshade box occupies most of the internal space of the curtain wall, the insulation thickness of the exterior wall is insufficient, the sunshade box louver top rail bracket and the guide wire fixing point have nowhere to take root, and the plate seams of the unitized curtain wall system occupy a space of 18mm thickness, and there is no space on the outside of the sunshade box to set horizontal and vertical seams.

[0004] This patent is to improve the above-mentioned existing technology in order to solve the dual contradictions of insufficient space and insufficient structural strength encountered in the process of processing sunshade boxes with metal composite panels. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0026] See also Figure 1-2 The present invention provides a technical solution: a metal composite plate external sunshade box structure, including an aluminum alloy window 1, a steel lintel 2 is provided at the outer end of one side of the aluminum alloy window 1, and the inner cavity of the steel lintel 2 is filled with rock wool 3. The main material of the rock wool 3 is inorganic fiber, which is usually made of natural rocks (such as basalt, dolomite, etc.) through high-temperature melting, centrifugal separation, solidification, shrinkage and other processes. The appearance and feel of the rock wool board are similar to asbestos, but it is softer and thinner than asbestos, and has better thermal insulation, sound insulation, fireproof, moisture-proof and other properties. An electric external sunshade system 8 is installed on the top left side of the aluminum alloy window 1. The electric external sunshade system 8 is an electric external sunshade device that can be purchased directly and belongs to the existing technology. It is driven by an electric motor and can conveniently control the lifting and lowering of the sunshade, thereby adjusting the light and temperature. It adopts a guide wire or a windproof side rail design, which can effectively block ultraviolet rays, reduce noise, and has a dustproof function;

[0027] The other end of the steel lintel 2 is connected to the side wall of the aerated concrete block wall 4, and a wall sleeve 5 is installed through the inner cavity of the aerated concrete block wall 4. Aluminum foil rock wool 6 is arranged on the left outer wall of the aerated concrete block wall 4. The aluminum foil rock wool 6 is a special thermal insulation material, which combines the characteristics of rock wool and aluminum foil. The rock wool board is made of basalt or slag as the main raw material, and is made into a plate shape after high-temperature melting into fibers, adding an appropriate amount of adhesive, and curing. Then, aluminum foil is pasted on the board surface. The aluminum foil layer on the surface of the aluminum foil rock wool board has good reflective properties and can reflect heat radiation. Combined with the thermal insulation properties of the rock wool board itself, the thermal insulation effect is greatly enhanced. The left end of the wall sleeve 5 extends into the inner cavity of the aluminum foil rock wool 6, and the left end of the wall sleeve 5 is connected to the top of the electric external sunshade system 8 through a connecting line;

[0028] The left outer wall of the steel lintel 2 is provided with a vacuum insulation panel 7, the left end of the electric outer sunshade system 8 is connected with an aluminum alloy split component 12, and the top of the aluminum alloy split component 12 is connected with a metal composite plate 13, the right end of the aluminum alloy split component 12 is connected with a hot-dip galvanized steel folding piece 11, and the hot-dip galvanized steel folding piece 11 is attached to the outer wall of the electric outer sunshade system 8,

[0029] In this embodiment, compared with the traditional process, the square steel keel inside the sunshade box is eliminated, and a 5mm thick L-shaped hot-dip galvanized steel folding part 11 is used as the load-bearing skeleton of the sunshade box. The outer side and top of the sunshade box formed by bending the metal composite are connected and fixed with the L-shaped hot-dip galvanized steel folding part 11 by rivets or self-tapping screws. After force calculation and on-site testing, the 5mm thick L-shaped hot-dip galvanized steel folding part 11 can ensure that the structural strength of the sunshade box is sufficient, and its rigidity can ensure that the metal composite plate 13 is installed flat, and ensure that the sunshade box on the electric external sunshade system 8 has sufficient wind pressure resistance. The horizontal section width of the L-shaped hot-dip galvanized steel folding part 11 is sufficient, and it can be used as a blind top rail bracket and a guide wire fixed end. The L-shaped hot-dip galvanized steel folding part 11 only occupies a width of 5mm, which can leave installation space for the horizontal and vertical joints of the curtain wall;
