Description

Technical Field

[0001] The present invention relates to the technical field of exterior wall insulation construction, and more particularly to a method for installing a graphene formwork-free insulation board. Background Art

[0002] With the rapid development of composite wall insulation, the application of structural integrated insulation systems has become more and more widespread. Graphene formwork-free insulation boards have gradually been put into use. However, as external formwork for cast-in-place structures, improper installation can easily lead to molding defects. The specific defects are as follows:

[0003] The problem of slurry leakage due to mold expansion at the root is prominent: In the traditional installation method, the junction between the insulation board and the floor structure (especially the root) is not tightly connected, and slurry leakage is easy to occur during concrete pouring, resulting in defects such as honeycomb and rough surface at the root of the wall, which requires later repair, increasing construction time and cost.

[0004] Insufficient reliability of the connection between the upper and lower layers: The upper and lower layers of insulation boards are usually spliced flatly, lacking effective staggered joints or tongue-and-groove interlocking structures. During concrete pouring, displacement is easily caused due to stress concentration, resulting in a loose connection between the insulation layer and the wall, affecting the overall insulation performance and structural stability.

[0005] The molding quality control is difficult: there is no standardized installation process, and it relies on manual experience adjustment, which makes it difficult to ensure the installation accuracy of the insulation board. As a result, the flatness and verticality deviations of the wall surface exceed the specification requirements and require repeated rectification. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a method for installing a graphene mold-free insulation board, which can effectively improve the molding quality and reduce the cost.

[0007] The present invention adopts the following technical solutions:

[0008] A method for installing a graphene mold-free insulation board comprises the following steps:

[0009] S1. Before the construction of the cast-in-place structure of this floor, fix the wooden planks horizontally at a position 50mm below the design elevation of the floor;

[0010] S2. After the concrete pouring of this layer is completed and the formwork is removed, the wooden squares are removed to form a tongue-and-groove with a depth of 50 mm;

[0011] S3. When installing the upper graphene mold-free insulation board, hang its bottom down into the tongue and groove of the current layer to close the seam;

[0012] S4. Pour the upper layer of concrete to form an upper and lower staggered structure between the insulation board and the wall.

[0013] Furthermore, in step S1, the height of the wooden block is 50 mm, and the bottom of the wooden block is located at the upper end of the insulation board.

[0014] Furthermore, after the pouring of one layer is completed, the back ribs are removed, and then the wooden squares are removed to form a tongue and groove.

[0015] Furthermore, in step S3, the back rib is installed first, and then the bottom of the upper insulation board is inserted into the tongue and groove, and the upper insulation board is connected to the lower insulation board.

[0016] Furthermore, after pouring is completed, the back ribs are removed, and staggered joints are formed between the insulation board and the poured wall.

[0017] Beneficial effects

[0018] This invention creates a tongue-and-groove structure by placing wooden planks and closing the seam with the upper insulation board. This effectively solves the problems of mold expansion at the base, grout leakage, and loose joints in the prior art, significantly improving molding quality and reducing construction costs. It is suitable for exterior wall insulation projects with cast-in-place concrete structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] As shown in the figure, the present invention discloses a method for installing a graphene mold-free insulation board, comprising the following steps:

[0025] S1. Before the construction of the cast-in-place structure of this floor, fix the wooden beam 1 horizontally at a position 50mm below the design elevation of the floor; generally, the top of the wooden beam 1 is flush with the elevation.

[0026] S2. After the concrete pouring of this layer is completed and the formwork is removed, the wooden square 1 is removed to form a tongue-and-groove 2 with a depth of 50 mm; the tongue-and-groove 2 is used to place the insulation board 3 above, so that the insulation board 3 and the wall 4 form an upper and lower staggered structure.

[0027] S3, when installing the upper graphene mold-free insulation board 3, hang its bottom down into the tongue and groove 2 of the current layer to close the seam;

[0028] S4. Pour the upper layer of concrete to form an upper and lower staggered joint structure between the insulation board 3 and the wall 4. The present invention creatively utilizes the wooden square 1 to form a tongue and groove 2 during pouring. After pouring is completed, the tongue and groove 2 is formed at the upper end of the insulation board 3. In this way, the insulation board 3 and the poured wall 4 form a staggered joint. Then, the lower end of the next insulation board 3 is clamped at the tongue and groove 2 to form a connection.

[0029] In one embodiment of the present invention, in step S1 , the height of the wooden square 1 is 50 mm, and the bottom of the wooden square 1 is located at the upper end of the insulation board 3 .

[0030] In one embodiment of the present invention, after one layer of casting is completed, the back ribs 5 are removed, and then the wood squares 1 are removed to form the tongue and groove 2. The two back ribs 5 are connected by a tension screw 6. Of course, other devices can also be used to connect the back ribs 5. Here, the back ribs 5 are only used for casting formwork.

[0031] In one embodiment of the present invention, in step S3 , the back rib 5 is first installed, and then the bottom of the upper insulation board 3 is inserted into the groove 2 , so that the upper insulation board 3 is butted against the lower insulation board 3 .

[0032] In one embodiment of the present invention, after pouring is completed, the back ribs 5 are removed, and staggered joints are formed between the insulation board 3 and the poured wall 4 .
