Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation wall panels, in particular to a composite thermal insulation outer template with a multi-layer structure. Background Art

[0002] The composite insulation outer formwork is a non-removable outer formwork, the conventional formwork is the inner formwork, concrete is poured in the middle, and the composite insulation outer formwork and the cast-in-place concrete components are firmly connected together through connectors to form a cavity-free external insulation composite insulation system. On this basis, the mortar leveling finishing layer and other practices are completed. The connector is a bolt body conventionally used in the prior art and is made of virgin nylon, a combination of nylon and metal, and has a horn end or a barb on the end.

[0003] However, when installing the connectors, the composite insulation outer formwork in the prior art is assembled by drilling holes on site and installing the connectors. This assembly method firstly causes a gap between the connector and the hole, which is not tightly sealed and affects the insulation effect. At the same time, if the connector is subjected to radial force, the force will be transmitted to the composite insulation outer formwork. The composite insulation outer formwork cannot withstand the extrusion and will be deformed, which seriously affects the insulation effect of the composite insulation outer formwork. In order to improve this situation, it is necessary to design a composite insulation outer formwork with a multi-layer structure. Utility Model Content

The prefabricated connecting member channel is used to install the connecting member connecting the composite thermal insulation outer formwork of the multi-layer structure.

[0009] Furthermore, annular protrusions are coaxially arranged on both sides of the radial reinforcement plate.

[0010] Furthermore, the connecting member prefabricated channel comprises:

[0013] Furthermore, the radial reinforcement plate is provided with through holes corresponding to the cross-sectional shapes of the main pipeline and the grouting channel.

[0014] Furthermore, the inner diameter of the main pipeline corresponds to the cross-sectional shape of the connecting piece of the composite thermal insulation outer template of the multi-layer structure.

[0015] In the above technical solution, the utility model provides a multi-layer composite thermal insulation outer formwork, which has the following beneficial effects:

[0016] Two layers of radial reinforcement plates are added to the traditional composite thermal insulation outer formwork to rigidly connect and cooperate with the prefabricated channel of the connecting piece for fixing the connecting piece. When the connecting piece is subjected to radial force, the extrusion force from this direction is borne by the radial reinforcement plate, and the surface contact between the radial reinforcement plate and the traditional composite thermal insulation outer formwork layer is used to improve the overall force strength, and then improve the overall support stability, and avoid the deformation of the composite thermal insulation outer formwork that affects the insulation effect.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] See also Figure 1-4 A composite thermal insulation outer template with a multi-layer structure includes a thermal insulation layer 1, an adhesive layer 2 and a thermal insulation transition layer 3 constituting the composite thermal insulation outer template, the thermal insulation layer 1, the adhesive layer 2 and the thermal insulation transition layer 3 are distributed in sequence, and an alkali-resistant mesh layer 4 is arranged on the outside of the thermal insulation layer 1 and the thermal insulation transition layer 3. The above is a conventional structure of the composite thermal insulation outer template in the prior art, and also includes:

[0026] The radial reinforcement plates 5 are two groups of radial reinforcement plates 5 symmetrically arranged on both sides of the thermal insulation layer 1 and are interlayers respectively located between the thermal insulation layer 1 and the bonding layer 2, and between the thermal insulation layer 1 and the alkali-resistant mesh layer 4. The area of ​​the radial reinforcement plates 5 is smaller than the areas of the thermal insulation layer 1, the bonding layer 2 and the thermal insulation transition layer 3. The radial force received by the connecting parts of the radial reinforcement plates 5 is dispersed to the entire surface of the radial reinforcement plates 5, and then dispersed to the thermal insulation layer 1, the bonding layer 2 and the alkali-resistant mesh layer 4, so as to improve the overall force load of the composite thermal insulation outer template with a multi-layer structure and improve the overall stability.

[0027] The prefabricated channel of the connecting piece runs through the composite thermal insulation outer formwork of the multi-layer structure and is also set through the center position of the two groups of radial reinforcement plates 5, so that the prefabricated channel of the connecting piece is in rigid contact with the radial reinforcement plate 5. The prefabricated channel of the connecting piece is used to install the connecting piece connecting the composite thermal insulation outer formwork of the multi-layer structure, so that the prefabricated channel of the connecting piece and the connecting piece can be sealed by injecting building sealant into the prefabricated channel of the connecting piece, so that the composite thermal insulation outer formwork of the multi-layer structure has a good sealing structure with the connecting piece, thereby ensuring the overall thermal insulation effect.

[0028] Furthermore, annular protrusions 6 are coaxially arranged on both sides of the radial reinforcement plate 5, so that the surface contact between the radial reinforcement plate 5 and the insulation layer 1, the adhesive layer 2 and the alkali-resistant mesh layer 4 is combined with the limiting effect between the annular protrusion 6 and the insulation layer 1, the adhesive layer 2 and the alkali-resistant mesh layer 4, thereby improving the bearing capacity of the connecting part in the radial force direction.

[0029] Furthermore, the prefabricated channel of the connecting piece includes:

[0030] The main pipeline 7 is set through the composite insulation outer template of the multi-layer structure and is also set through the center position of the two groups of radial reinforcement plates 5. The main pipeline 7 is used to install a connector connecting the composite insulation outer template of the multi-layer structure;

[0031] The grouting channel 8 is arranged on the side surface of the main pipeline 7 along the axial direction of the main pipeline 7 , and a grouting notch 9 connected to the grouting channel 8 is opened on the side surface of the main pipeline 7 .

[0032] Specifically, the building sealant is injected through the grouting channel 8, which is open at both ends. The injected building sealant enters the main pipe 7 through the grouting notch 9, and enters between the inner wall of the main pipe 7 and the connecting piece to achieve adhesion and fixation. After the building sealant fills the main pipe 7, the grouting channel 8 and the grouting notch 9, the sealing operation is completed.

[0033] Furthermore, the radial reinforcement plate 5 is provided with a through hole 10 corresponding to the cross-sectional shape of the main pipeline 7 and the grouting channel 8, so that the main pipeline 7 and the grouting channel 8 can be in closer contact with the radial reinforcement plate 5 during assembly, so that the radial reinforcement plate 5 can better withstand the pressure from the connecting parts.

[0034] Furthermore, the inner diameter of the main pipe 7 corresponds to the cross-sectional shape of the connector of the composite insulation outer template of the multi-layer structure, so as to avoid shaking between the main pipe 7 and the connector, making the entire assembly structure more stable.

[0035] To sum up, the composite thermal insulation outer formwork of the present multi-layer structure adds two layers of radial reinforcement plates to the traditional composite thermal insulation outer formwork to perform rigid connection and cooperation with the prefabricated channel of the connecting piece for fixing the connecting piece. When the connecting piece is subjected to radial force, the extrusion force from this direction is borne by the radial reinforcement plate, and the surface contact between the radial reinforcement plate and the traditional composite thermal insulation outer formwork layer is used to improve the overall force strength, and then improve the overall support stability, thereby avoiding the deformation of the composite thermal insulation outer formwork and affecting the insulation effect. At the same time, the prefabricated channel of the connecting piece can be sealed and fixed with the connecting piece by pouring construction sealant, thereby ensuring the stable connection between the connecting piece and the composite thermal insulation outer formwork and also ensuring the sealing effect, thereby improving the overall thermal insulation effect of the composite thermal insulation outer formwork of the present multi-layer structure.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
