Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a decorative thermal insulation reverse wall using point-broken bridges and gap blocking and a construction method. Background Art

[0002] The exterior insulation system of building exterior walls is an important means to achieve building energy conservation. The existing building exterior walls are divided into decorative curtain walls and the use of decorative insulation integrated panels and the building exterior walls. For decorative curtain walls, metal fixings are required to install the external curtain walls on metal keels. The metal fixings are in direct contact with the metal keels. The metal keels do not have insulation functions. They form a heat and cold bridge with the building exterior walls, becoming an energy exchange channel between the indoor and outdoor areas of the building, which will reduce the thermal insulation performance of the building exterior wall system, thereby increasing the energy consumption required for building heating or cooling. The decorative insulation integrated system is also an important part of the exterior wall insulation system. Figure 1 The installation method of the existing decorative thermal insulation integrated panel shown is to combine the decorative panel 100 and the thermal insulation layer 200 into one to form an integrated panel with thermal insulation and decorative effects. The integrated panel is usually provided with a sink groove around the decorative panel 100, and the metal connector 1 is inserted into the board seam along the thickness direction of the board. The outdoor end of the metal connector 1 is embedded in the sink groove for limiting, and the indoor end of the metal connector 1 is fixed to the building exterior wall 300. The above existing installation structure makes the metal connector 1 an energy exchange channel between indoor and outdoor, and the board seam where the metal connector 1 is located is easy to form Figure 1 The triangular cold bridge radiation area 2 shown does not meet the design requirements for use on the exterior wall of a low-energy building. Therefore, it is necessary to solve the cold bridge problem existing in the exterior wall insulation system.

[0003] The invention patent with announcement number CN201411801Y discloses a "new type of building thermal insulation exterior wall". The patent uses a lightweight curtain wall panel to be installed on the building exterior wall with a U-shaped curtain wall metal fixing. In order to avoid the energy exchange problem caused by the direct contact between the U-shaped curtain wall metal fixing and the building exterior wall, the patent adds a pad of thermal insulation hard plastic or wooden pad between the U-shaped curtain wall metal fixing and the building exterior wall. However, the U-shaped curtain wall metal fixing, the pad of thermal insulation hard plastic or wooden pad, and the building exterior wall still need to be fixed by screws. Although the U-shaped curtain wall metal fixing does not directly contact the building exterior wall, there is still a cold bridge line along the U-shaped curtain wall metal fixing-screw-building exterior wall that cannot be blocked, making the improvement effect of this solution poor. In addition, this solution only considers the cold bridge problem caused by metal connectors, and ignores the improvement of the cold bridge problem at the board seam. Summary of the invention

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] This embodiment discloses a decorative thermal insulation back wall using point-break bridges and gap blocking, such as Figures 2 to 5 As shown, it mainly includes a decorative panel 100, an insulation layer 200 and a concrete layer 400, wherein the decorative panel 100 and the insulation layer 200 are an integrated unit panel formed by compounding, and the concrete layer 400 is formed by splicing multiple integrated unit panels and then pouring on the insulation layer 200 through a reverse beating process.

[0026] The interior of the above-mentioned integrated decorative insulation exterior wall is provided with metal connectors and a thermal insulation structure. The metal connector in this embodiment adopts a flat head bolt 3. The structure of the flat head bolt 3 is as follows: Figure 4 As shown, the main body of the flat head bolt 3 is a screw rod 301, and a stop plate 302 having an outer diameter greater than that of the screw rod 301 is provided at one end of the screw rod 301. The thermal insulation structure is divided into a thermal insulation member 4 arranged at points and an extruded strip 6 arranged along the board seam. A recessed groove needs to be pre-opened at the board seam around the decorative panel 100 of each integrated unit board, and the recessed groove is used to limit the stop plate 302 at the end of the flat head bolt 3 inserted into the board seam.

[0027] Multiple integrated unit panels are spliced ​​together, and a thermal insulation member 4 is provided at each intersection of the panel seams (i.e., the intersection of the horizontal panel seams and the vertical panel seams) on one side of the insulation layer 200. The thermal insulation member 4 in this embodiment is made of injection-molded resin, and its structure is as follows: Figure 3 As shown, the thermal insulation component 4 includes a cylindrical body 401, one end of the body 401 is provided with a flange 404 whose outer diameter is larger than that of the body 401, and the side wall of the other end of the body 401 is provided with a convex rib 403, the convex rib 403, the side wall of the body 401, and the flange 404 together enclose a slot 406 with an open side, a non-through threaded hole 402 is provided on the end of the body 401 opposite to the flange 404, and an exhaust hole 405 penetrating the flange 404 is provided on the edge of the flange 404.

[0028] Based on the above structure, the specific structure and construction method of the decorative insulation back wall designed by the present invention are as follows (combined with Figure 2 As shown, in order not to cover the reinforcing ribs, the extruded strips 6 embedded between adjacent thermal insulation members 4 are omitted).

[0029] Step 1: A sink groove is opened around the decorative panel 100, and the decorative panel 100 and the insulation layer 200 are compounded to form an integrated unit board;

[0030] Step 2: splice multiple integrated unit panels together and lay them on a formwork table, with the insulation layer 200 of each integrated unit panel facing upwards;

[0031] Step 3: insert a flat head bolt 3 at each intersection of the board seams, and the limiting plate 302 at the end of the flat head bolt 3 is limited by the recessed groove at the edge of the decorative panel 100. After the flat head bolt 3 is inserted, the recessed groove is sealed with a sealant, and a non-metallic compression gasket 5 with an opening is sleeved on the end of the flat head bolt 3 exposed from the thermal insulation layer 200 (this embodiment uses a rubber compression gasket to avoid using a metal gasket to increase the area of ​​the cold bridge radiation zone), and the thermal insulation component 4 with a threaded hole is tightened with the flat head bolt 3, so that the flat head bolt 3 is screwed into the inside of the thermal insulation component 4 without being exposed; at this time, the thermal insulation component 4 can not only block the cold bridge of the flat head bolt 3, but also play the role of a nut, and with the cooperation of the limiting plate 302, the compression gasket 5 and the thermal insulation component 4, the two integrated unit panels spliced ​​to each other are tightly clamped.

[0032] Step 4: Lay an extruded strip 6 on the board seam between adjacent thermal insulation components 4. The width of the extruded strip 6 is greater than the width of the board seam. The end of the extruded strip 6 is embedded in the slot on the adjacent thermal insulation component 4 and fixed (such as Figure 5 shown);

[0033] Step 5: Finally, a reinforcing rib 7 is provided on the insulation layer 200 of the plurality of spliced ​​integrated unit panels, and concrete is poured on the insulation layer 200 to form a concrete layer 400, so that the concrete layer 400 covers the thermal insulation member 4. Since the flange 404 of the thermal insulation member 4 in this embodiment is provided with an exhaust hole 405, exhaust can be conducted through the exhaust hole 405 when pouring concrete.

[0034] The present invention arranges the thermal insulation member 4 which integrates the functions of positioning, pressing and thermal insulation at the intersection of the plate seams in the form of point thermal insulation, and blocks the cold bridge line at the flat head bolt 3 inserted into the plate seams by the thermal insulation member 4. The thermal insulation member 4 is also used to fit and fix the extruded board strip 6 arranged along the plate seams, and the extruded board strip 6 can block the cold bridge line at the plate seams of the integrated unit board, which has a better thermal insulation effect than the method in the prior art, and is very suitable for use on the exterior walls of ultra-low energy consumption buildings.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
