Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an external wall with integrated thermal insulation structure. Background Art

[0002] In order to improve the thermal insulation performance of the building wall, it is usually necessary to install prefabricated insulation panels on the exterior wall of the building. In the prior art, the exterior wall prefabricated insulation panels are usually installed on the exterior surface of the exterior wall by means of bonding, anchoring, and external hanging. Among them, the bonding construction method easily causes hollowing between the prefabricated insulation panels and the exterior wall of the structure, the anchoring construction method easily causes the prefabricated insulation panels to separate from the main building and fall off due to the aging and deformation of the anchor nails, and the large-size prefabricated insulation panels used in the external hanging construction method have low installation efficiency and are prone to water accumulation and freezing cracking at the joints.

[0003] The Chinese utility model patent "A construction structure combining aluminum formwork of a pull-tab system and prefabricated insulation board for exterior walls" (CN208430780U, 2019.01.25) discloses an exterior wall structure and construction method using prefabricated insulation boards as cast-in-place concrete exterior formwork. Although this exterior wall integrates the prefabricated insulation board with the cast-in-place part, the prefabricated insulation board and the cast-in-place part are only connected by pull tabs. After long-term use, the connection between the prefabricated insulation board and the pull tab is prone to failure due to repeated temperature difference deformation, and there is a risk of the prefabricated insulation board and the cast-in-place part being separated. In addition, in its construction method, the prefabricated insulation board is only supported by the steel frame fixing the prefabricated insulation board. When the cast-in-place part is poured, the bottom of the prefabricated insulation board is under huge concrete pressure. The prefabricated insulation board may easily rupture due to pressure and leak on the spot, or the ruptured part may fall off due to temperature difference stress in the later stage. The method of increasing the thickness of the prefabricated insulation board to improve its compressive strength will easily increase the weight of the prefabricated insulation board, and special lifting facilities will be required for on-site construction. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the prefabricated insulation board in the integrated exterior wall of the insulation structure in the prior art is easily separated from the cast-in-place part due to repeated temperature difference deformation. An integrated exterior wall of the insulation structure is provided to make the connection between the prefabricated insulation board and the cast-in-place part more reliable.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: constructing an integrated insulation structure exterior wall, including a prefabricated insulation board and a cast-in-place wall with a steel grid, the prefabricated insulation board includes an anchor bolt with one end embedded in the prefabricated insulation board and the other end extending into the cast-in-place wall, an anchor cable with one end embedded in the prefabricated insulation board and the other end connected to the steel grid of the cast-in-place wall, the anchor bolt and the anchor cable are evenly distributed on the inner surface of the prefabricated insulation board.

[0006] Furthermore, the vertical dimension of the prefabricated insulation board matches the vertical dimension of the cast-in-place wall, and the prefabricated insulation board matches the horizontal dimension of the cast-in-place wall by horizontal close splicing, so that the prefabricated insulation board is at the same height as the exterior wall of the building in the vertical direction and is closely spliced ​​in the horizontal direction, thereby reducing vertical leakage points and ensuring the overall flatness of the facade, facilitating the later decoration construction of the facade.

[0007] Furthermore, transverse connecting ribs are provided at the vertical joints of two adjacent prefabricated insulation panels, and both ends of the transverse connecting ribs are respectively connected to the anchor bolts of the two adjacent prefabricated insulation panels, so that the two adjacent prefabricated insulation panels are tightly connected to prevent the vertical joints from cracking and affecting the building facade.

[0008] Furthermore, the prefabricated insulation board is provided with through holes for template connection parts, so that the inner and outer templates can be quickly connected during installation and construction, thereby improving construction efficiency.

[0009] Furthermore, a supporting mesh is provided in the prefabricated insulation board, and one end of the anchor bolt pre-buried in the prefabricated insulation board is connected to the supporting mesh, so that the temperature difference deformation between the prefabricated insulation board and the cast-in-place wall is smaller.

[0010] Furthermore, a supporting mesh is provided in the prefabricated insulation board, and one end of the anchor cable pre-buried in the prefabricated insulation board is connected to the supporting mesh, thereby further reliably connecting the prefabricated insulation board to the outside of the cast-in-place wall.

[0011] The implementation of the thermal insulation structure integrated exterior wall of the utility model has the following beneficial effects: by evenly distributing anchor bolts on the inner surface of the prefabricated thermal insulation board, and one end of the anchor bolt is embedded in the prefabricated thermal insulation board and the other end extends into the cast-in-place wall, the prefabricated thermal insulation board and the cast-in-place wall are positioned and connected together, and when temperature difference deformation occurs, the evenly distributed anchor bolts can ensure that the prefabricated thermal insulation board can be reliably positioned on the outer surface of the cast-in-place wall. By evenly distributing anchor cables on the inner surface of the prefabricated thermal insulation board, and one end of the anchor cable is embedded in the prefabricated thermal insulation board and the other end is connected to the steel mesh of the cast-in-place wall, the prefabricated thermal insulation board can be reliably connected to the outer side of the cast-in-place wall to prevent it from detaching. The corresponding construction method is to make the outer formwork close to the outer side of the prefabricated thermal insulation board, and use the outer formwork to withstand the pouring pressure caused by the cast-in-place concrete on the prefabricated thermal insulation board during pouring, so as to ensure that the prefabricated thermal insulation board will not crack during the pouring process, and avoid leakage on the spot or partial detachment at a later stage.
