Description

Technical Field

[0001] The utility model relates to the technical field of composite formwork, and more specifically to a cast-in-place concrete exterior wall thermal insulation composite formwork. Background Technique

[0002] With the rapid development of the construction industry, higher requirements for building energy-saving exterior wall thermal insulation have been put forward everywhere. Currently, buildings usually add a layer of thermal insulation composite formwork to the exterior wall to insulate the interior and prevent the entry of cold air, so as to increase the comfort inside the building. At present, the basic method of building exterior wall thermal insulation is to install and fix the thermal insulation board by bonding and anchoring after the cast-in-place concrete shear wall construction is completed.

[0003] For example, a cast-in-place concrete exterior wall thermal insulation composite formwork with the prior art publication number CN215563600U. This utility model is fixedly connected by anchor bolts. The anchor bolts are fixed in the thermal insulation reinforcement layer, pass through the thermal insulation material layer and the inner anti-cracking mortar protection layer in sequence, and then insert into the cast-in-place concrete wall.

[0004] However, the above-mentioned prior art still has the following problems when in use: when installing the thermal insulation composite formwork, it is usually installed after the concrete exterior wall has solidified, with low installation efficiency. Moreover, re-drilling holes in the exterior wall to install fixing parts such as screws will also damage the exterior wall and affect the firmness between the thermal insulation composite formwork and the exterior wall. Based on this, the utility model provides a cast-in-place concrete exterior wall thermal insulation composite formwork. Content of the Utility Model

[0005] In order to overcome the above defects of the prior art, the utility model provides a cast-in-place concrete exterior wall thermal insulation composite formwork. By using the inner plate as the formwork for pouring concrete on the exterior wall, it can not only reduce the use cost, but also improve the firmness between the thermal insulation composite formwork and the concrete exterior wall, and at the same time improve the installation efficiency of the thermal insulation composite formwork. The thermal insulation board and the thermal insulation mortar layer are provided to play a thermal insulation role, so as to solve the problems occurring in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a cast-in-place concrete exterior wall thermal insulation composite formwork, including a formwork assembly.
