Description

Technical Field

[0001] This invention relates to an external wall insulation connection structure and wall, belonging to the technical field of building insulation wall panels. Background Technology

[0002] With the rapid development of the construction industry, composite insulation wall panels are increasingly being used for building exteriors. During the construction of composite walls, to ensure a smooth and stable process, it is often necessary to use limiting connectors to fix both sides of the insulation layer, and simultaneously, tie bolts are needed to secure the formwork.

[0003] Patent No. CN201910943622.0 discloses a construction method for an insulated exterior wall, comprising: Step 1: Prefabricating insulation modules in a factory; Step 2: Tying a steel reinforcement frame; Step 3: Connecting the prefabricated insulation modules to the outside of the steel reinforcement frame; Step 4: Supporting an outer formwork on the outside of the insulation modules, forming a first pouring space between the outer formwork and the insulation modules, and supporting an inner formwork on the inside of the steel reinforcement frame, forming a second pouring space between the insulation modules and the inner formwork; Step 5: Pouring concrete in the first and second pouring spaces respectively.

[0004] The aforementioned patent requires fixing the insulation layer and template separately in two stages: first, fixing both sides of the insulation layer, and then fixing the templates on both sides of the insulation layer. This makes the wall construction process cumbersome and affects the efficiency of wall construction. It also cannot effectively guarantee the precise distance between the templates on both sides, and cannot ensure that the insulation layer and wire mesh in the middle will not shift. The bonding force between the insulation layer and the concrete layer is poor, and the adhesion is prone to failure later. The concrete layers cannot form an effective connection, resulting in poor load-bearing capacity and stability of the overall wall. In addition, the installation process of the wire mesh is inconvenient and prone to skewing during installation, making it impossible to guarantee flatness. Summary of the Invention

[0005] This invention addresses the shortcomings of the prior art by providing an external wall insulation connection structure and wall, which can reduce the number of steps in the wall construction process and improve the efficiency of wall construction; it can effectively ensure the precise distance between the templates on both sides, ensuring that the insulation layer and wire mesh in the middle will not shift; it can improve the bonding force between the insulation layer and the concrete layer, and improve the load-bearing capacity and stability of the wall; it can make the wire mesh installation convenient and ensure flatness.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] An external wall insulation connection structure includes a hollow connecting pipe, one end of which is fitted with a limiting connector; the limiting connector includes a first baffle, a second baffle, and a third baffle; the limiting connector also includes an installation groove located between the first baffle and the second baffle; the installation groove limits the position of the wire mesh; the second baffle and the third baffle limit the position of the intermediate insulation layer.

[0008] Furthermore, the limiting connector includes a first limiting connector, which includes a first baffle; a first tube is provided on one side of the first baffle, and a first retaining seat is provided on the other side; the first tube and the first retaining seat are coaxially arranged and interconnected.

[0009] Furthermore, the end of the first tube body furthest from the first baffle is provided with an external thread.

[0010] Furthermore, the first card holder is provided with multiple limiting claws, and the first card holder is engaged with the connecting pipe through the limiting claws; each limiting claw includes a first connecting part, which is disposed on the end face of the first baffle and is evenly distributed around the axis of the first baffle.

[0011] Furthermore, the first connecting portion is provided with a first protrusion; the first protrusion is disposed on the first connecting portion at one end away from the first baffle; the first protrusion faces the axial direction of the first baffle.

[0012] Furthermore, the first card holder has several casting holes on its tube wall; the first card holder has a first snap-fit ​​hole on its outer surface, which is located at the end of the first card holder away from the first baffle; and the first card holder has multiple circumferentially distributed mounting grooves on its end face.

[0013] Furthermore, the limiting connector also includes a second limiting connector, which includes a second retaining seat and a second stop plate arranged coaxially; the second retaining seat engages with the first retaining seat.

[0014] Furthermore, the second card holder has multiple claws on its end face; each claw includes a second connecting portion, which is disposed on the body of the second card holder and is evenly distributed around the axis of the second card holder; the second connecting portion has a second protrusion, which is located at the end of the second connecting portion away from the second baffle; the second protrusion is disposed in a direction away from the axis of the second baffle; the second protrusion engages with the first engaging hole.

[0015] Furthermore, the limiting connector also includes a third limiting connector; the third limiting connector includes an integrally formed third baffle and nut; the third limiting connector is threadedly connected to the first pipe body.

[0016] An external wall insulation wall adopts the above-mentioned external wall insulation connection structure; the wall includes an intermediate insulation layer, through which a connecting pipe passes, with both ends of the connecting pipe located within a protective concrete layer and a structural concrete layer, and the insulation layer is positioned by a first baffle and a third baffle; a first bracket and a second bracket are provided within the protective concrete layer, and the first bracket and the second bracket fix the position of the wire mesh.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] The external wall insulation connection structure and wall provided by the present invention have a first limiting connector and a third limiting connector threaded together to fix the insulation layer, a second limiting connector snapping into the first limiting connector to fix the wire mesh, and a tie bolt inserted in the connecting pipe to fix the templates on both sides.

[0019] This invention achieves an integrated design of the limiting connector and the tie bolt, eliminating the need for separate fixing of the insulation layer and the template, thus reducing the number of steps in the wall construction process and improving the efficiency of wall construction.

[0020] This invention eliminates the use of concrete blocks as supports and PVC pipes as perforated pipes, reducing costs, decreasing the number of holes and cold bridge points per unit square area, thereby improving thermal insulation performance and construction efficiency.

[0021] After the wall in this invention is poured and shaped, the connecting pipe can be retained in the wall as a reinforcing rib, which can improve the bonding force between the insulation layer and the concrete layer and avoid the phenomenon of weak bonding. The connecting pipe can also form an effective anchoring force between the concrete layers on both sides of the insulation layer, which can improve the load-bearing capacity and stability of the wall.

[0022] The wire mesh is fixed by the snap-fit ​​between the second limiting connector and the first limiting connector, making the installation of the wire mesh convenient. In addition, the wire mesh can avoid tilting during the installation process and ensure flatness by the snap-fit ​​between multiple sets of second limiting connectors and first limiting connectors.
