Description

Technical Field

[0001] The utility model belongs to the technical field of building exterior wall insulation, and particularly relates to a non-removable composite insulation formwork for cast-in-place concrete walls. Background Art

[0002] The cast-in-place concrete insulation system with a composite formwork uses the composite insulation formwork as a non-removable formwork. Concrete is poured on the inner side, and the composite insulation formwork is firmly connected to the cast-in-place concrete through connectors. A flat layer and a plastering layer are made on the outer side to form a non-cavity composite insulation cast-in-place concrete wall structure, which is abbreviated as the composite formwork insulation system.

[0003] The composite insulation formwork is prefabricated in a factory and plays the roles of a non-removable formwork and heat insulation in the construction of cast-in-place concrete projects. It is at least composed of an outer enhanced protection layer, a heat insulation board, and heat insulation transition layers and inner bonding reinforcement layers arranged on both sides of the heat insulation board.

[0004] Among them, after long-term use of the heat insulation board, the bonding of the heat insulation transition layer and the inner bonding reinforcement layer to the heat insulation board will fail to a certain extent, resulting in cracking at the bonding part with the heat insulation board, and thus affecting its normal use. Summary of the Utility Model

[0005] The utility model provides a non-removable composite insulation formwork for cast-in-place concrete walls to solve the defects in the prior art.

[0006] The utility model is realized through the following technical solutions:

[0007] A non-removable composite insulation formwork for cast-in-place concrete walls includes a heat insulation board body located between a heat insulation transition layer and an inner bonding reinforcement layer. A plurality of strip-shaped through grooves are formed in the heat insulation board body. The strip-shaped through grooves penetrate the heat insulation board body along its thickness direction and are perpendicular to the side surface of the heat insulation board body. Heat insulation slurry is provided between the heat insulation board body and the heat insulation transition layer, and the heat insulation transition layer and the inner bonding reinforcement layer are penetrated through the strip-shaped through grooves.

[0008] In the utility model, a plurality of strip-shaped through grooves are arranged in the heat insulation board body in the thickness direction and the strip-shaped through grooves penetrate the heat insulation board body, which can enable the heat insulation slurry to fill the strip-shaped through grooves, thereby improving the bonding strength between the heat insulation board body and the heat insulation transition layer and the inner bonding reinforcement layer, making the heat insulation board body, the heat insulation transition layer and the inner bonding reinforcement layer integrated as a whole, and preventing cracking at the bonding part between the heat insulation board body and the heat insulation transition layer and the inner bonding reinforcement layer.

[0009] Preferably, the strip-shaped through grooves are arranged in a rectangular array on the insulation board body, and 4 to 10 strip-shaped through grooves are provided per square meter. Arranging 4 to 10 strip-shaped through grooves per square meter in a rectangular array can increase the bonding strength between the insulation board body, the thermal insulation transition layer and the inner bonding reinforcement layer on the premise of meeting the structural strength of the insulation board body.

[0010] Preferably, the length of the strip-shaped through groove is 50 mm to 150 mm, and the width is 4 mm to 12 mm.

[0011] Preferably, the distance between the strip-shaped through groove and the edge of the insulation board body is not less than 50 mm, which can facilitate the processing of the strip-shaped through groove and prevent the edge of the insulation board body from being damaged during the processing of the strip-shaped through groove.

[0012] The beneficial effects of the present utility model are as follows: by arranging a plurality of strip-shaped through grooves in the thickness direction of the insulation board body, and the strip-shaped through grooves penetrate through the insulation board body, the thermal insulation slurry can be filled into the strip-shaped through grooves, thereby improving the bonding strength between the insulation board body, the thermal insulation transition layer and the inner bonding reinforcement layer, making the insulation board body, the thermal insulation transition layer and the inner bonding reinforcement layer integrated as a whole, and preventing cracks from occurring at the bonding part between the insulation board body, the thermal insulation transition layer and the inner bonding reinforcement layer.

It includes a thermal insulation board body 2, with a thermal insulation transition layer 5 and an inner bonding reinforcement layer 6 provided on both sides of the thermal insulation board body 2 respectively. The inner bonding reinforcement layer 6 is bonded to the side surface of the cast-in-place concrete wall 1. A plurality of strip-shaped through grooves 3 are formed in the thermal insulation board body 2. The strip-shaped through grooves 3 penetrate the thermal insulation board body 2 along its thickness direction, and the strip-shaped through grooves 3 are perpendicular to the side surface of the thermal insulation board body 2. There is thermal insulation slurry between the thermal insulation board body 2 and the thermal insulation transition layer 5. The thermal insulation transition layer 5 and the inner bonding reinforcement layer 6 are penetrated through by the strip-shaped through grooves. The thermal insulation slurry passes over the thermal insulation board body 2 through the strip-shaped through grooves 3 and bonds with the inner bonding reinforcement layer 6.

[0021] In the present utility model, a plurality of strip-shaped through grooves 3 are arranged in the thickness direction of the thermal insulation board body 2 and the strip-shaped through grooves 3 penetrate the thermal insulation board body 2, which can enable the thermal insulation slurry 4 to fill the strip-shaped through grooves 3, thereby improving the bonding strength between the thermal insulation board body 2 and the thermal insulation transition layer 5 and the inner bonding reinforcement layer 6, making the thermal insulation board body 2, the thermal insulation transition layer 5 and the inner bonding reinforcement layer 6 integrated as a whole, and preventing cracks from occurring at the bonding positions of the thermal insulation board body 2, the thermal insulation transition layer 5 and the inner bonding reinforcement layer 6.

[0022] The length of the strip-shaped through groove 3 is 50 mm to 150 mm, and the width is 4 mm to 12 mm.

[0023] The distance between the strip-shaped through groove 3 and the edge of the thermal insulation board body 2 is not less than 50 mm, which can facilitate the processing of the strip-shaped through groove 3 and prevent the edge of the thermal insulation board body 2 from being damaged during the processing of the strip-shaped through groove 3.

[0024] The strip-shaped through grooves 3 are arranged in a rectangular array on the thermal insulation board body 2 and 4 to 10 strip-shaped through grooves 3 are provided per square meter. Among them, the optimal number is 4 strip-shaped through grooves 3 per square meter. Arranging 4 to 10 strip-shaped through grooves 3 per square meter and in a rectangular array can increase the bonding strength between the thermal insulation board body 2 and the thermal insulation transition layer 5 and the inner bonding reinforcement layer 6 on the premise of meeting the structural strength of the thermal insulation board body 2.

[0025] The utility model arranges a plurality of strip-shaped through grooves 3 in the thickness direction of the insulation board body 2, and at the same time, the strip-shaped through grooves 3 penetrate through the insulation board body 2, so that the thermal insulation slurry 4 can fill the strip-shaped through grooves 3, thereby improving the bonding strength between the insulation board body 2, the thermal insulation transition layer 5 and the inner bonding strengthening layer 6, making the insulation board body 2, the thermal insulation transition layer 5 and the inner bonding strengthening layer 6 integrated as a whole, and preventing cracks from appearing at the bonding positions of the insulation board body 2, the thermal insulation transition layer 5 and the inner bonding strengthening layer 6.
