Description

Technical Field

[0001] This invention relates to the field of building materials technology, and in particular to a thermal insulation wall panel for building exterior walls and its manufacturing process. Background Technology

[0002] Prefabricated construction refers to the transfer of a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Compared to cast-in-place construction, prefabricated construction can save energy and resources, reduce labor, and improve construction quality.

[0003] Traditional exterior wall sandwich insulation composite wall panels consist of insulation material placed between inner and outer wall panels, connected together by connectors to form a "sandwich" structure. During installation, they are connected to a concrete steel frame structure via connectors, such as... Figure 1 As shown, during construction, the exterior wall panels are first laid on one side of the concrete steel frame structure to be poured; then, holes are drilled in the exterior wall panels and nylon connectors or metal composite connectors are inserted, so that the barbed sections of the connectors extend into the concrete steel frame structure. Concrete is then poured, and finally a stable connection between the exterior wall panels and the concrete is achieved.

[0004] The above-mentioned insulated exterior wall panels have the following problems in use: Since the service life of the connectors is much shorter than that of reinforced concrete, the connectors will be damaged or fall off after a long time, causing the exterior wall panels to fall off the concrete structure, which poses a safety hazard.

DETAILED DESCRIPTION

[0054] The embodiments of the present application will be described in detail by way of specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in the specification. The present application can also be implemented or applied by other different embodiments, and the details in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0055] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0056] Example 1

[0057] like Figures 1 to 7 As shown, a thermal insulation wall panel for building exterior walls includes an insulation core layer 1. To increase the structural strength of the insulation core layer 1, unit reinforcement channels are provided through the sidewalls of the insulation core layer 1. The unit reinforcement channels are connected to the main bonding channel 107. The unit reinforcement channels are configured as four channels, namely a first channel 101 and a second channel 102 that are horizontally arranged through the insulation core layer 1 and parallel to each other; and a third channel 103 and a fourth channel 104 that are vertically arranged through the insulation core layer 1 and parallel to each other.

[0058] Specifically, the first channel 101, the second channel 102, the third channel 103 and the fourth channel 104 are arranged in a grid pattern to form cross-shaped connections; the main bonding channel 107 is configured as four channels, which are connected to the cross-shaped connections.

[0059] To simplify the opening of the four channels in the insulation core layer, the insulation core layer 1 is designed to be composed of an inner core layer 12 and an outer core layer 11 joined together.

[0060] Specifically, the inner core layer 12 includes an inner core 1200, a first channel groove A1201 and a second channel groove A1202 that are horizontally parallel to each other along the inner side surface of the inner core 1200; and a third channel groove A1203 and a fourth channel groove A1204 that are vertically parallel to each other along the inner side surface of the inner core 1200. Specifically, the first channel groove A1201, the second channel groove A1202, the third channel groove A1203, and the fourth channel groove A1204 are preferably set as semicircles.

[0061] The outer core layer 11 includes an outer core 1100, a first channel groove B1101 and a second channel groove B1102 that are horizontally parallel to each other along the inner side surface of the outer core 1100; and a third channel groove B1103 and a fourth channel groove B1104 that are vertically parallel to each other along the inner side surface of the inner core 1200. The first channel groove B1101, the second channel groove B1102, the third channel groove B1103, and the fourth channel groove B1104 have the same structure as the inner core layer 12, and are preferably set as semi-circular.

[0062] In this scheme, the first channel slot A1201 and the first channel slot B1101 are combined to form the first channel 101;

[0063] The second channel groove A1202 and the second channel groove B1102 are combined to form a second channel 102; the third channel groove A1203 and the third channel groove B1103 are combined to form a third channel 103; and the fourth channel groove A1204 and the fourth channel groove B1104 are combined to form a fourth channel 104. The channel grooves are provided in a semicircular shape, and when the two groups of channel grooves are spliced, a circular channel is formed. It is worth noting that, in the present scheme, considering the difficulty of slotting, the semicircular shape is preferred, and the rectangular shape or other axisymmetric shapes can also be provided.

[0064] In order to realize the stable installation of the inner core 1200 and the outer core 1100, a first T-shaped groove 1205 is arranged on the outer edge of the inner core 1200, and a second T-shaped groove 1105 is arranged on the outer edge of the outer core 1100; the first T-shaped groove 1205 and the second T-shaped groove 1105 are spliced to form an I-shaped groove 105; and the I-shaped block 4 is embeddedly arranged in the I-shaped groove 105.

[0065] The outer wall panel 2 is adhesively arranged on the front side of the thermal insulation core layer 1; and the inner wall panel 3 is adhesively arranged on the inner side of the thermal insulation core layer 1; the outer wall panel 2 and the inner wall panel 3 are formed by pouring polymeric mortar, and a reinforcing net is additionally arranged in the outer wall panel 2 and the inner wall panel 3 to increase the structural strength of the outer wall panel 2 and the inner wall panel 3; the reinforcing net is used to improve the impact resistance and bending resistance of the formwork, and can be a rigid alkali-resistant glass fiber mesh, a hot-dipped galvanized welded mesh, or a galvanized steel sheet expansion mesh.

[0066] The main adhesion channel 107 is arranged through the inner wall panel 3 and the thermal insulation core layer 1; when the concrete is poured, the concrete flows into the main adhesion channel 107 and is adhesively arranged on the inner side surface of the outer wall panel 2, and the connecting member formed by the solidification of the concrete has high pulling force, thereby increasing the adhesion strength of the outer wall panel 2 and the concrete. In the present embodiment, the section surface of the main adhesion channel 107 is in any shape, and is preferably circular, and can also be square or hexagonal.

[0067] In order to realize the adhesion function of the adjacent wall panels above and below and left and right, the side wall of the thermal insulation core layer 1 is provided with a connecting groove 106; the connecting groove 106 is located at the two ends of the first channel 101, the second channel 102, the third channel 103, and the fourth channel 104. Specifically, the adjacent connecting grooves 106 form a connecting cavity, and when the concrete is poured, the mud flows into the connecting cavity through the unit reinforcing channel, and after the concrete is solidified, the adjacent wall panels can be stably connected together.

[0068] In order to increase the connection strength of the main bonding channel 107 and the outer wall panel 2, the front side of the heat preservation core layer 1 is provided with a reinforcing groove 1107, and the right end of the main bonding channel 107 communicates with the reinforcing groove 1107. In this scheme, the main bonding channel 107 is preferably provided as four, and the reinforcing groove 1107 is provided as a rectangular groove, and the right end of the four main bonding channels 107 communicates with the four corners of the rectangular groove. When the concrete is poured, the mud will enter the reinforcing groove 1107 through the main bonding channel 107 and be stably bonded with the outer wall panel.

[0069] In order to increase the waterproof performance of the outer wall panel 2, the upper end of the outer wall panel 2 is provided with a diagonal notch 21, and the upper end of the outer wall panel 2 is provided with a diagonal protrusion 22. When the upper and lower two adjacent outer wall panels 2 are butted, the diagonal protrusion 22 of the upper part is embedded with the diagonal notch 21 of the lower part.

[0070] In this scheme, from the aspect of connection effect, the existing nylon connecting piece is usually 60kg in pull-out test, while the pull-out force of a single main bonding channel of the present application is 300kg. The reason is that in this scheme, since the inner and outer wall panels and the poured concrete are made of the same material, when the concrete is poured, the concrete entering the main bonding channel will be bonded with the reinforcing groove 1107 and the inner surface of the outer wall panel 2, and under the cooperation of the four channels, a reticular structure composed of concrete will be formed. When the concrete solidifies, the reinforcing groove 1107, the main bonding channel 107 and the four channels form an integral whole, which is much larger than the bonding strength of the nylon connecting piece or the steel connecting piece and the concrete.

[0071] Embodiment 2

[0072] A production process of a heat preservation and insulation wall panel for building outer wall, comprising the following steps:

[0073] S1: preparation of the heat preservation core layer: pouring the core material block through the mold, and cutting and flattening the core material block to obtain unit core material and I-shaped block; specifically, the heat preservation core layer is specifically expandable polystyrene particles, which are foamed once, aged, foamed twice, aged, then stirred, poured into a mold, and molded by pressure casting, and cured after demolding.

[0074] S2: preparation of the inner and outer core bodies: setting a channel groove, a T-shaped groove and a connecting groove on the unit core material to obtain an inner core body, and setting a reinforcing groove on the outer side of the inner core body to obtain an outer core body;

[0075] S3: assembling of the heat preservation core layer: aligning the inner core body and the outer core body, and embedding the I-shaped block to form the heat preservation core layer;

[0076] S4: polymer mortar preparation: the polymer mortar raw materials are stirred to prepare the polymer mortar; the mortar is prepared by dry mixing cement, water-washed dry sand and additives, and then water is added and stirred to form the polymer mortar.

[0077] S5: inner wall plate laying: the polymer mortar is coated on the inner side of the thermal insulation core layer, then the reinforcing mesh is laid, and the polymer mortar is coated again to form the inner wall plate, thereby obtaining the prefabricated wall plate, and the prefabricated wall plate is cured;

[0078] S6: drilling: the prefabricated wall plate after curing is drilled along the inner wall plate side and cleaned; by arranging the drilling sequence before laying the outer wall plate, the drilling depth can be easily controlled; at this time, the drilling mode is direct through drilling; compared with drilling after laying the outer wall plate, the drilling depth cannot be accurately controlled, sometimes the outer wall plate is damaged, and sometimes the drilling position is only in the thermal insulation core layer; the drilling depth of the present preparation method can be accurately controlled, and the main bonding channel drilled has the best effect.

[0079] S7: outer wall plate laying: the polymer mortar is coated on the inner side of the prefabricated wall plate, then the reinforcing mesh is laid, and the polymer mortar is coated again to form the outer wall plate, and the outer wall plate is cured; in the present scheme, the curing method can be natural curing, steam curing or heat and moisture curing.

[0080] As shown in Figure 8 , the structure is installed on the outer side of the unreinforced frame structure, and when the concrete is poured, the concrete mortar will simultaneously enter the first channel 101, the second channel 102, the third channel 103 and the fourth channel 104 in the four channels, and also enter the reinforcing groove 1107 and the connecting groove 106; the connecting piece formed by the reinforcing groove 1107 and the main bonding channel 107 can realize stable polymerization of the outer wall plate 2, the thermal insulation core layer 1 and the inner wall plate 1, and can also realize stable bonding with the pouring body 100.

[0081] After the concrete in the four channels is bonded, a skeleton support structure is formed, the structural strength of the thermal insulation core layer 1 is increased, and the pull-out strength of the connecting piece formed by the main bonding channel 107 is further increased.

[0082] After the concrete in the connecting groove 106 is bonded, the connection between adjacent wall plate structures can be enhanced, so that the entire outer wall plate forms a large whole, and the occurrence of local falling is further reduced.

[0083] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
