Description

Technical Field

[0001] This invention relates to the field of building metal composite panel curtain wall engineering technology, specifically to a metal composite panel external sunshade curtain box structure and its construction process. Background Technology

[0002] Due to the requirements of building function and energy-saving design, public buildings and industrial buildings need to install external sunshades on the outside of windows 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 a sunshade box to achieve a unified appearance between the curtain wall and the sunshade box.

[0003] According to the provisions of the "General Code for Civil Building Construction," the area encompassed by the outer edge of the curtain wall panel must be included in the building area. Therefore, from an economic perspective, the distance between the curtain wall panel and the main structural exterior wall should be designed to be as small as possible to reduce the unusable building area. Thus, the problem of insufficient installation space for the sunshade box cannot generally be solved by increasing the distance between the curtain wall panel and the main structural exterior wall. Instead, special measures must be taken within the limited space. The distance between the curtain wall panel and the main structural exterior wall is generally designed to be 200mm-250mm. Completing the curtain wall panel, sunshade box, and exterior wall insulation construction within this width is extremely challenging due to space constraints. Traditionally, the width of the square steel keel section for the sunshade box cannot exceed 30mm. The keel of this specification does not provide reinforcement, resulting in insufficient structural strength of the sunshade box, inadequate flatness during installation, and insufficient wind pressure resistance. In addition, the keel is too small, making it difficult to bend the metal composite panel. Since the sunshade box occupies most of the interior space of the curtain wall, the external wall insulation thickness is insufficient, and there is nowhere to anchor the louver top rail bracket and guide wire of the sunshade box. The panel joints of the unitized curtain wall system require 18mm of thickness space, and there is no space on the outside of the sunshade box to set horizontal and vertical joints.

[0004] This patent addresses the aforementioned improvement to existing technologies in response to the dual contradictions of insufficient space and insufficient structural strength encountered during the processing of sunshade boxes from metal composite panels. Summary of the Invention

[0005] The purpose of this invention is to provide a metal composite panel external sunshade box structure to solve the problems mentioned in the background art.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-2 This invention provides a technical solution: a metal composite panel external sunshade box structure, including an aluminum alloy window 1, a steel lintel 2 set at one outer end of the aluminum alloy window 1, and rock wool 3 filled in the inner cavity of the steel lintel 2. The main material of the rock wool 3 is inorganic fiber, usually made from 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 finer than asbestos, and has better heat insulation, sound insulation, fire resistance, moisture resistance 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, which can be purchased directly and belongs to the prior art. It is driven by an electric motor and can easily control the raising and lowering of the sunshade, thereby adjusting the light and temperature. It adopts a guide wire or 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 the inner cavity of the aerated concrete block wall 4 is equipped with a through-wall sleeve 5. Aluminum foil rock wool 6 is installed on the left outer wall of the aerated concrete block wall 4. Aluminum foil rock wool 6 is a special thermal insulation material that combines the characteristics of rock wool and aluminum foil. The rock wool board is made of basalt or slag as the main raw material, which is melted into fibers at high temperature, a suitable amount of binder is added, and it is cured and processed into a board shape. 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, it greatly enhances the thermal insulation effect. The left end of the through-wall sleeve 5 extends into the inner cavity of the aluminum foil rock wool 6, and the left end of the through-wall sleeve 5 is connected to the top of the electric external sunshade system 8 through a connecting line.

[0028] A vacuum insulation panel 7 is installed on the left outer wall of the steel lintel 2. An aluminum alloy joint assembly 12 is connected to the left end of the electric external sunshade system 8, and a metal composite panel 13 is connected to the top of the aluminum alloy joint assembly 12. A hot-dip galvanized steel folding member 11 is connected to the right end of the aluminum alloy joint assembly 12, and the hot-dip galvanized steel folding member 11 is in close contact with the outer wall of the electric external sunshade system 8.

[0029] In this embodiment, compared with the traditional process, the internal square steel keel of the sunshade box is eliminated. A 5mm thick L-shaped hot-dip galvanized steel folding piece 11 is used as the load-bearing frame of the sunshade box. The outer side and top of the sunshade box formed by bending the metal composite are connected and fixed to the L-shaped hot-dip galvanized steel folding piece 11 by rivets or self-tapping screws. After stress calculation and on-site testing, the 5mm thick L-shaped hot-dip galvanized steel folding piece 11 can ensure that the structural strength of the sunshade box is sufficient. Its rigidity can ensure that the metal composite panel 13 is installed flat and that the wind pressure resistance of the sunshade box on the electric external sunshade system 8 is sufficient. The horizontal section of the L-shaped hot-dip galvanized steel folding piece 11 is wide enough to serve as the louver top rail bracket and the fixed end of the guide steel wire. The L-shaped hot-dip galvanized steel folding piece 11 only occupies 5mm of width, which can leave installation space for the horizontal and vertical joints of the curtain wall.

[0030] The top of the electric external sunshade system 8 is equipped with a hot-dip galvanized steel angle bracket 9, and the outer end of the hot-dip galvanized steel angle bracket 9 is connected to a hot-dip galvanized steel pipe 10. The electric external sunshade system 8, the hot-dip galvanized steel folding piece 11, the hot-dip galvanized steel angle bracket 9 and the hot-dip galvanized steel pipe 10 are all set inside the metal composite plate 13.

[0031] Preferably, the vacuum insulation board 7 is placed between the steel lintel 2 and the electric external sunshade system 8, and the vacuum insulation board 7 is a 30mm Class A vacuum board. The inner side of the sunshade box on the electric external sunshade system 8 is replaced with the vacuum insulation board 7 instead of the rock wool insulation board. Since the heat transfer coefficient of the vacuum insulation board 7 is more than 3 times lower than that of rock wool, the thickness of the external wall insulation can be reduced from 75mm to 30mm. Thus, the external wall insulation performance is not reduced, or even improved, under the condition that the insulation layer thickness is greatly reduced.

[0032] Preferably, the top of the hot-dip galvanized steel folding member 11 is positioned between the electric external sunshade system 8 and the hot-dip galvanized steel corner bracket 9, and the dimensions of the hot-dip galvanized steel folding member 11 are 275x125x5mm.

[0033] Preferably, the metal composite plate 13 is disposed on the outermost side, and the thickness of the metal composite plate 13 is 4mm.

[0034] Preferably, the cross-section of the hot-dip galvanized steel pipe 10 is opposite to the cross-section of the hot-dip galvanized steel angle bracket 9, and the dimensions of the hot-dip galvanized steel pipe 10 are 100x80x4mm, where 80mm is its cross-sectional diameter.

[0035] Preferably, the aluminum alloy joint assembly 12 includes a hollow fastener 121. A hollow connector 123 is snapped onto the right end of the hollow fastener 121 via a clip. The interlocking of the hollow fastener 121 and the hollow connector 123 facilitates disassembly and maintenance. Two sets of identical spring clips 122 are symmetrically arranged at the top and bottom of the hollow fastener 121. The outer ends of the spring clips 122 abut against the outer wall of the metal composite plate 13. A fastening screw 124 is installed on the inner right side of the hollow connector 123. The fastening screw 124 passes through the hot-dip galvanized steel folding piece 11. The top of the hollow connector 123 is engaged with the limiting piece 125. The outer wall of the left end of the limiting piece 125 is connected to the metal composite plate 13 by the mounting screw 126. The outer wall of the left end of the hollow connector 123 is connected to the outer wall of the electric external sunshade system 8 by the mounting screw 126. The spring piece 122 is a T-shaped spring piece, and the top and bottom of the hollow fastener 121 are provided with limiting grooves that match the spring piece 122.

[0037] s1. Make a hole in the aerated concrete block wall 4, install the through sleeve 5 inside the aerated concrete block wall 4, and install the aluminum foil rock wool 6 on the outer wall of the aerated concrete block wall 4.
