Description

Technical Field

[0001] The utility model relates to the field of prefabricated buildings, and particularly relates to a non-removable penetrating ultra-low energy consumption lightweight hanging board system. Background Technique

[0002] When retrofitting existing buildings to achieve ultra-low energy consumption, especially for brick-concrete, steel-concrete and other buildings, the existing walls are mainly concrete walls or masonry walls. To increase the thermal insulation of the exterior wall, a thick thermal insulation board is attached to the existing wall, and the external thermal insulation board is mainly constructed by adhesive and anchor methods. However, for the ultra-low energy consumption retrofit of industrial buildings with a portal frame or steel frame as the main body and metal flat plates or metal sandwich panels as the walls, the above-mentioned adhesive and anchor methods are not applicable because thermal insulation construction using adhesive and anchor methods cannot be carried out on metal-faced walls. If the original metal-faced wall is demolished and rebuilt, it will affect the use of the original building and may also have an adverse impact on the main structure. Content of the Utility Model

[0003] The utility model discloses a non-removable penetrating ultra-low energy consumption lightweight hanging board system for the ultra-low energy consumption retrofit of existing buildings with metal keels and metal-faced walls, without the need to demolish the original metal wall, and without the need for formwork and scaffolding during construction.

[0005] A non-removable penetrating ultra-low energy consumption lightweight hanging board system includes a C-shaped adapter, a penetrating screw, an adjusting nut, a through-length aluminum frame, an aluminum alloy sub-frame and a vacuum sandwich panel. A through-hole is opened on the original metal wall of the existing building, and a through-hole is also opened on the C-shaped adapter. The C-shaped adapter is fixedly installed on the original metal keel of the existing building. The penetrating screw sequentially passes through the through-hole of the C-shaped adapter and the through-hole of the original metal wall and is exposed. A through-hole is opened on the through-length aluminum frame. The exposed end of the penetrating screw is fixedly installed on the through-length aluminum frame through the adjusting nut. The penetrating screw passes through the through-length aluminum frame. The aluminum alloy sub-frame is fixedly connected to the vacuum sandwich panel through back bolts.

[0007] Further, the aluminum alloy sub-frame is divided into a male aluminum alloy sub-frame and a female aluminum alloy sub-frame. The male aluminum alloy sub-frame and the female aluminum alloy sub-frame are respectively fixed on two vacuum sandwich panels that need to be spliced with each other through back bolts. The male aluminum alloy sub-frame is connected to the female aluminum alloy sub-frame, and an adjusting screw is vertically arranged on the male aluminum alloy sub-frame towards the ground.

[0008] Further, rubber pads are respectively provided on the contact surfaces between the male aluminum alloy sub-frame and the female aluminum alloy sub-frame and the vacuum sandwich panel.

Aerogel roll felts are filled in the gaps between the polyurethane single-sided stickers of two spliced vacuum sandwich panels up and down in a continuous length, and the spliced board joints are sealed with sealant and foam rods.

[0010] Further, the cross-sections of the male aluminum alloy sub-frame and the female aluminum alloy sub-frame are both Z-shaped. One ends of the male aluminum alloy sub-frame and the female aluminum alloy sub-frame are respectively fixed on the vacuum sandwich panel by back bolts, while the other ends of the male aluminum alloy sub-frame and the female aluminum alloy sub-frame respectively form hollow cavities with only one side open. Plug plates are respectively provided on the hollow cavity of the male aluminum alloy sub-frame and the continuous aluminum frame. The plug plate of the continuous aluminum frame is inserted into the hollow cavity of the male aluminum alloy sub-frame from the open end, and the plug plate of the male aluminum alloy sub-frame is inserted into the hollow cavity of the female aluminum alloy sub-frame from the open end. The left and right relative positions between the male aluminum alloy sub-frame and the continuous aluminum frame are adjustable, the left and right relative positions between the male aluminum alloy sub-frame and the female aluminum alloy sub-frame are adjustable, and the up and down relative positions between the male aluminum alloy sub-frame and the continuous aluminum frame are adjustable by adjusting screws.

The materials selected for the above structure have a lower bulk density and have little impact on the main structure of the existing building. The designed lightweight hanging board system can take into account the heat preservation and airtightness structures, especially having great advantages for the low-carbon and low-energy consumption transformation of industrial buildings. When the scheme designed by the utility model is constructed, there is no need to demolish the original metal wall, so it does not affect the normal use function of the existing building, and the construction is carried out by an assembly method without the need to set up formwork and scaffolding.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0019] In this embodiment, a solution is designed for the ultra-low energy consumption renovation of existing buildings. Taking an existing building that uses metal keels as the enclosure system and installs metal sandwich panels or metal flat plates on the metal keels as the wall as an example for explanation. In order to reduce the energy consumption of existing buildings, in this embodiment, a vacuum sandwich panel 1 is hung outside the original metal wall 2. The following combines the attached Figure 1 and Figure 2 to describe the structure of the non-dismantling penetration type ultra-low energy consumption lightweight wall panel system in this embodiment.

[0020] The entire lightweight wall panel system is mainly assembled by a C-shaped adapter 14, a full-thread penetrating screw 17, an adjusting nut sleeved on the penetrating screw 17, a continuous aluminum frame 13 with a C-shaped cross-section, an aluminum alloy sub-frame, and a vacuum sandwich panel 1. Among them, a plurality of C-shaped adapters 14 are arranged at intervals along the vertical direction of the original metal keel 3. The C-shaped adapter 14 can be directly welded to the original metal keel 3 or fixed to the original metal keel 3 by bolts. When installing the C-shaped adapter 14, the open end of the C-shaped adapter 14 faces outward, and through holes are symmetrically opened on the two flanges of the C-shaped adapter 14. Through holes are also opened on the original metal wall 2 corresponding to the through holes of the C-shaped adapter 14. The diameter of the through hole on the original metal wall 2 can be slightly larger than the outer diameter of the penetrating screw 17. The full-thread penetrating screw 17 is sequentially passed through the through holes on the two flanges of the C-shaped adapter 14 and the through holes on the original metal wall 2, and both ends of the penetrating screw 17 extend out and are exposed. A rubber gasket 16 is provided between the C-shaped adapter 14 and the original metal wall 2 to avoid contact wear.

[0021] One end of the penetrating screw 17 near the C-shaped adapter 14 is sleeved with an adjusting nut 15. Just loosen the adjusting nut 15, and the exposed length of the penetrating screw 17 can be adjusted. The exposed length of the penetrating screw 17 only needs to meet the installation of the full-length aluminum frame 13. After the adjustment is in place, lock the adjusting nut 15. After the exposed length of the penetrating screw 17 is adjusted in place, use polyurethane foam material to seal the gap between the penetrating screw 17 and the original metal wall 2, and use an airtight film material 18 to seal the periphery of the penetrating screw 17 and the outer joint of the original metal wall 2.

[0022] As described above, the cross-section of the full-length aluminum frame 13 is C-shaped, with its open end facing the side of the original metal wall 2. A through hole is opened on the full-length aluminum frame 13. The full-length aluminum frame 13 is sleeved on one end of the penetrating screw 17 exposed outside the original metal wall 2, and adjusting nuts 11 are respectively sleeved on both sides of the full-length aluminum frame 13 on the penetrating screw 17. The position of the full-length aluminum frame 13 on the penetrating screw 17 is adjusted by the adjusting nuts 11, and after the adjustment is in place, lock the adjusting nuts 11. A vertical insertion plate is also provided on the full-length aluminum frame 13.

[0023] In this embodiment, a lightweight hanging plate with heat preservation performance, namely a vacuum sandwich panel 1, is adopted. Multiple vacuum sandwich panels 1 are vertically spliced and hung on the outside of the original metal wall 2. Before hanging the vacuum sandwich panel 1, aluminum alloy sub-frames need to be fixedly installed at both ends of the back of each vacuum sandwich panel 1. The aluminum alloy sub-frame at the lower end of each vacuum sandwich panel 1 is a male aluminum alloy sub-frame 5, and the one at the upper end is a female aluminum alloy sub-frame 4. The structures of the two types of aluminum alloy sub-frames are similar, and their cross-sections are approximately Z-shaped. One end of the male aluminum alloy sub-frame 5 and the female aluminum alloy sub-frame 4 are respectively fixed on the back of the vacuum sandwich panel 1 through cement board back bolts 6, while the other ends of the male aluminum alloy sub-frame 5 and the female aluminum alloy sub-frame 4 respectively form a hollow cavity with only one side open. The above structure is the common point of the two types of aluminum alloy sub-frames. The difference is that the opening directions of the male aluminum alloy sub-frame 5 and the female aluminum alloy sub-frame 4 are exactly opposite, and an insertion plate is vertically arranged on one side of the hollow cavity of the male aluminum alloy sub-frame 5 relative to the female aluminum alloy sub-frame 4. The outer wall of the hollow cavity of the male aluminum alloy sub-frame 5 extends outward to form a connecting plate, and holes are opened on the connecting plate. When the male aluminum alloy sub-frame 5 and the female aluminum alloy sub-frame 4 are respectively connected to the vacuum sandwich panel 1, a hard rubber pad 7 is arranged on the contact surface between the two to avoid direct contact and wear.

[0024] After completing the assembly of the above aluminum alloy sub-frame and the vacuum sandwich panel 1, taking the hanging installation of the upper vacuum sandwich panel 1 and the lower vacuum sandwich panel 1 as an example, align the open end of the hollow cavity of the male aluminum alloy sub-frame 5 at the upper end of the lower vacuum sandwich panel 1 with the insertion plate on the lower through aluminum frame 13 and insert the insertion plate into the hollow cavity. Insert the adjusting screw 12 into the opening of the connecting plate of the male aluminum alloy sub-frame 5 at the upper end of the lower vacuum sandwich panel 1. The installation height of the lower vacuum sandwich panel 1 can be finely adjusted through the adjusting screw 12. The open end of the hollow cavity of the female aluminum alloy sub-frame 4 at the lower end of the upper vacuum sandwich panel 1 faces downward, and the insertion plate on the male aluminum alloy sub-frame 5 at the upper end of the lower vacuum sandwich panel 1 is inserted into the hollow cavity of the female aluminum alloy sub-frame 4 at the lower end of the upper vacuum sandwich panel 1.

[0025] In this embodiment, the female aluminum alloy sub-frame 4 is only used for wind resistance and does not bear vertical loads. The male aluminum alloy sub-frame 5 and the through aluminum frame 13 can slide horizontally left and right to facilitate the adjustment of the position in the horizontal direction. The male aluminum alloy sub-frame 5 and the female aluminum alloy sub-frame 4 can also slide horizontally left and right to adjust the position in the horizontal direction. After the positions of the three are adjusted, set ethylene propylene diene monomer (EPDM) rubber strips 10 at the gap between the open end of the hollow cavity of the male aluminum alloy sub-frame 5 and the insertion plate of the through aluminum frame 13, and also set EPDM rubber strips 10 at the gap between the open end of the hollow cavity of the female aluminum alloy sub-frame 4 and the insertion plate of the male aluminum alloy sub-frame 5. Clamp them tightly through the EPDM rubber strips 10 to avoid relative movement. Set polyurethane single-sided stickers 8 between the hollow cavity of the male aluminum alloy sub-frame 5 and the vacuum sandwich panel 1, and also set polyurethane single-sided stickers 8 between the hollow cavity of the female aluminum alloy sub-frame 4 and the vacuum sandwich panel 1. The polyurethane single-sided stickers 8 are used to enhance the protection ability against the cold bridge of the gap. Aerogel roll felts 9 are filled throughout the gap between the polyurethane single-sided stickers 8 of the two vertically spliced vacuum sandwich panels 1, and the spliced plate joints are sealed with sealant and foam rods 19.

The scope of the present invention is defined by the appended claims and their equivalents.
