Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an external wall with integrated insulation structure and a prefabricated insulation board thereof. 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 panels for exterior walls" (CN208430780U, 2019.01.25) discloses an exterior wall structure and a construction method thereof that utilizes prefabricated insulation panels as the exterior formwork for cast-in-place concrete. Although this exterior wall integrates the prefabricated insulation panels with the cast-in-place part, the prefabricated insulation panels and the cast-in-place part are only connected by pull tabs. After long-term use, the connection between the prefabricated insulation panels and the pull tabs is prone to failure due to repeated temperature difference deformation, and there is a risk of the prefabricated insulation panels being detached from the cast-in-place part. In addition, the prefabricated insulation panels have a large horizontal dimension. Although the risk of cracking caused by vertical joints is avoided, the weight of a single prefabricated insulation panel is large, and large-scale lifting equipment is required for construction. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an integrated exterior wall with an insulation structure, which is not easy to crack due to the heavy weight of a single prefabricated insulation board in the integrated exterior wall with an insulation structure in the prior art and the easy cracking at the vertical joints.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: constructing an integrated exterior wall of an insulation structure, including a prefabricated insulation board and a cast-in-place wall, the prefabricated insulation board including a prefabricated insulation layer and a connector at one end of which is embedded in the prefabricated insulation layer and the other end of which extends into the cast-in-place wall; a plurality of the prefabricated insulation boards are spliced ​​and arranged on the outside of the cast-in-place wall, and connecting dowels are provided between two adjacent prefabricated insulation boards; dowel holes matching the connecting dowels are reserved at the end faces of the prefabricated insulation layers of the prefabricated insulation boards at the joints; an inclined surface inclined toward the cast-in-place wall is provided on the end faces of the prefabricated insulation layers of the prefabricated insulation boards at the joints, and the dowel holes are provided on the inclined surface.

[0006] Furthermore, the inclined surface starts to incline from the middle of the end surface of the prefabricated thermal insulation layer at the joint, so that the end surface of the prefabricated thermal insulation layer at the joint can retain some right-angle edges, ensuring that the joint is flat and not easily knocked off during construction.

[0007] Furthermore, a rebar countersunk hole is provided on the end surface of the joint of the prefabricated insulation board at the rebar hole, so that the concrete of the cast-in-place wall can flow into the rebar countersunk hole, thereby connecting the middle part of the rebar to the cast-in-place wall.

[0008] Furthermore, the prefabricated insulation board is also provided with a supporting mesh embedded in the prefabricated insulation layer, and one end of the connecting piece embedded in the prefabricated insulation board is connected to the supporting mesh, so that the entire prefabricated insulation board can be reliably connected to the cast-in-place wall.

[0009] Another technical problem to be solved by the present invention is to provide a prefabricated insulation board for an integrated exterior wall with an insulation structure, which makes the wall joints less likely to crack and is more convenient to construct, in order to solve the problem that the prefabricated insulation board for an integrated exterior wall with an insulation structure in the prior art has a large dead weight, resulting in inconvenience in construction and easy cracking at the vertical joints.

[0010] The utility model solves another technical problem by means of a technical solution: constructing a prefabricated insulation board of an integrated exterior wall of an insulation structure as described above, comprising a prefabricated insulation layer and a connector having one end embedded in the prefabricated insulation layer and the other end extending into the cast-in-place wall; the end face of the prefabricated insulation layer is provided with a dowel hole matched with the connecting dowel; the end face of the prefabricated insulation layer is provided with an inclined surface inclined toward the cast-in-place wall, and the dowel hole is arranged on the inclined surface.

[0011] Furthermore, a reinforcement insertion countersunk hole is provided on the end surface of the prefabricated thermal insulation layer at the reinforcement insertion hole.

[0012] The implementation of the thermal insulation structure integrated exterior wall and its prefabricated thermal insulation board of the utility model has the following beneficial effects: by setting the prefabricated thermal insulation board including the thermal insulation layer and the connecting parts, and the connecting parts are respectively connected between the prefabricated thermal insulation layer and the cast-in-place wall, the prefabricated thermal insulation board can be reliably connected to the outside of the cast-in-place wall to prevent the device from detaching. By splicing and setting multiple prefabricated thermal insulation boards on the outside of the cast-in-place wall, the dead weight of a single prefabricated thermal insulation board can be effectively reduced, and it can be transported by simple hoisting equipment or manual labor, which is convenient for construction; by setting connecting dowels between two adjacent prefabricated thermal insulation boards, the two prefabricated thermal insulation boards can be reliably spliced ​​together to prevent cracking at the vertical joints.

According to actual conditions, the prefabricated thermal insulation boards can be spliced ​​horizontally to set vertical joints, or vertically to set horizontal joints.

[0027] In this preferred embodiment, the prefabricated insulation layer 11 of the prefabricated insulation board can be prefabricated with lightweight concrete or lightweight insulation mortar, wherein the aggregate used in the lightweight concrete or lightweight insulation mortar can be one or more of modified polystyrene particles, expanded clay, expanded perlite, modified glass microspheres, thermosetting polystyrene, composite aluminum silicate and other materials.

It is best to set an inclined surface 11b on the end face 11a at the joint, and the inclined surface 11b is inclined toward the cast-in-place wall 20, so that the concrete of the cast-in-place wall can flow into the joint 1 during pouring, so that the middle part of the connecting dowel 13 is connected to the cast-in-place wall. It is preferred that the inclined surface starts to tilt from the middle part of the end face 11a of the prefabricated insulation layer at the joint, so that the end face of the prefabricated insulation layer at the joint can retain a part of the right-angle plane 11c to ensure the smoothness of the joint.
