Description

Technical Field

[0001] This utility model relates to the field of wall construction technology, and in particular to an insulated wall panel connector and a green building exterior wall insulation system. Background Technology

[0002] In building exterior wall insulation systems, reliable fixing of the insulation board to the wall is a crucial step in ensuring insulation performance and structural safety. With the promotion of lightweight and energy-saving building materials in green building, hollow bricks have become one of the mainstream materials for exterior wall construction due to their light weight, excellent sound insulation, and thermal insulation properties. However, when applying traditional expansion bolt fixing methods to hollow brick walls, the core structural characteristics of hollow bricks result in a significantly lower bond strength between the insulation board and the hollow bricks compared to solid walls.

[0003] In scenarios where solid walls are connected to insulation boards, expansion bolts penetrate the wall, causing the internal expansion tubes to open and form a tight, enveloping contact with the solid structure inside the wall, thus creating a stable interlocking structure. However, because hollow bricks have internal cavities, the area where the expansion tubes are opened after the bolts pierce the hollow brick is not supported by solid wall material and only contacts the thin wall of the hollow brick. This prevents the interlocking structure of the expansion tubes found in solid walls from being achieved. The bolts and walls are only fixed by the local friction of the thin wall, resulting in a much lower bonding strength compared to solid wall scenarios.

[0004] In summary, traditional expansion bolt fixing methods are poorly compatible with the hollow cavity structure of hollow bricks, failing to form an efficient interlocking structure and easily leading to problems such as loosening of the insulation board. Therefore, this study investigated a connector for insulation wall panels and an external insulation wall system for green buildings. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes a thermal insulation wall panel connector and a green building exterior wall insulation system.

[0006] The technical solution to the technical problem solved by this utility model is as follows: This utility model proposes a thermal insulation wall panel connector, including a cylinder, a drive rod that can move linearly and be positioned inside the cylinder, two clamping petals connected to one end of the drive rod, and a communicating opening and a clamping port between the two clamping petals. When the drive rod moves linearly along the inside of the cylinder, the inner wall of the cylinder interferes with the two clamping petals, causing the two clamping petals to retract inward and be placed inside the cylinder; a pressure cap is threadedly connected to the other end of the drive rod.

[0007] Preferably, the drive rod includes a screwing part and a connecting part that are rotatably connected to each other. When the screwing part is threadedly connected to the inner wall of the cylinder, it drives the connecting part to move linearly within the cylinder.

[0008] Preferably, the inner wall of the cylinder is provided with at least one set of guide grooves, and the outer wall of the connecting part is connected with at least one set of guide protrusions. The guide protrusions are placed in the guide grooves and are slidably arranged along the guide grooves.

[0009] Preferably, one end of the screwing part has a rotating groove with a "T" shaped cross-section, and one end of the connecting part is fixed with a connector with a "T" shaped cross-section. The connector is appropriately arranged in the rotating groove and forms a structure that can rotate relative to each other.

[0010] Preferably, the portion of the drive rod located outside the cylinder is connected to a screw ring.

[0011] Preferably, the clamping opening is located in the middle of the opening slit, so that the front part of the opening slit forms an entrance space and the rear part forms a space for the two clamping petals to retract inward.

[0012] This utility model also proposes a green building exterior wall insulation system, comprising: an insulation inner wall formed by several sets of hollow bricks, wherein one side wall of each hollow brick has a perforation, and vertically arranged reinforcing ribs are fixed in the insulation inner wall; an insulation wall panel connector as described above, wherein one end of the insulation wall panel connector freely passes through the perforation and clamps the reinforcing ribs by the contraction of the two clamping flaps; an insulation board having several sets of stepped holes inside, wherein the inner wall of the insulation board passes through the stepped holes and then fits against the outer wall of the hollow bricks, and is positioned between the hollow bricks and the outer wall by threaded connection of the pressure cap and the other end of the drive rod; and a finishing layer constructed on the outer wall of the insulation board.

[0013] Preferably, the hollow brick is filled with heat-insulating and / or sound-insulating grout.

[0014] Preferably, the outer end of the pressure cap is flush with the outer surface of the insulation board, or placed on the inner side of the outer surface of the insulation board.

[0015] The above technical solution has the following advantages or beneficial effects: 1. In this utility model, the insulation wall panel connector uses a drive rod to retract the clamping flaps, forming a tight engagement with the reinforcing ribs. This allows the tensile force of the connector to be directly transmitted to the reinforcing ribs, eliminating the reliance on the thin walls of the hollow bricks. Furthermore, the clamping caps hold the insulation board between the caps and the hollow bricks, creating a bidirectional constraint. The clamping flaps enhance the pull-out resistance and positioning of the insulation wall panel connector, while the clamping caps secure the insulation board. The combination of these two elements provides both pull-out resistance and clamping constraint on the insulation board, effectively preventing problems such as loosening of the insulation board.

[0016] 2. In this utility model, the clamping petal is designed to be concealed, which can avoid interference between the clamping petal and the outer wall of the hollow brick during the penetration process. This makes it easier for the insulation wall panel connector to maintain a close fit with the inner wall of the hole after the hole is penetrated, thus reducing the gap between the two.

[0025] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0027] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] like Figures 1 to 3 As shown, this embodiment proposes a thermal insulation wall panel connector c, including a cylinder 1. A linearly movable and positionable drive rod 2 is disposed inside the cylinder 1. One end of the drive rod 2 is connected to two clamping petals 3, which are arranged outwardly and are elastic. A communicating opening slit 4 and a clamping opening 5 are provided between the two clamping petals 3. The opening slit 4 provides space for the entry of reinforcing bars, and the clamping opening 5 clamps the reinforcing bars. When the drive rod 2 moves linearly along the inside of the cylinder 1, the inner wall of the cylinder 1 interferes with the two clamping petals 3, causing them to move inward and retract, allowing the clamping opening 5 to clamp and position the reinforcing bars, and placing a portion of the clamping petals 3 inside the cylinder.

[0029] It also includes a pressure cap 6, which has a threaded section at the end of the drive rod 2 away from the clamping petal 3, and the pressure cap 6 is positioned at the other end of the drive rod 2 by a threaded connection.

[0030] In actual use, the two clamping petals 3 are initially placed inside the cylinder 1. After the insulation wall panel connector c penetrates the hollow brick a, the driving rod 2 is moved, causing the two clamping petals 3 to move linearly and eventually open outwards outside the cylinder 1, allowing the reinforcing rib b to be placed in the clamping opening 5 between the two clamping petals 3. Subsequently, the driving rod 2 is moved in the opposite direction, causing the two clamping petals 3 to move, resulting in interference between the inner wall of the cylinder 1 and the two clamping petals 3. This causes the two clamping petals 3 to move and contract in a centered manner, thereby clamping the reinforcing rib b and positioning it in its current position.

[0031] In this design, the clamping petal 3 is designed to be concealed, which avoids interference between the clamping petal 3 and the outer wall of the hollow brick a during the penetration process. This allows the insulation wall panel connector c to remain in close contact with the inner wall of the perforation g after penetrating the perforation g, thus reducing the gap between the two.

[0032] refer to Figure 2 In some embodiments, the drive rod 2 includes a screwing part 21 and a connecting part 22 that are rotatably connected to each other. The screwing part 21 is threadedly connected to the inner wall of the cylinder 1, and the end of the screwing part 21 away from the clamping petal 3 extends to the outside of the cylinder 1. By manually rotating the screwing part 21 outside the cylinder 1, the screwing part 21 is threadedly connected to the inside of the cylinder 1, thereby driving the connecting part 22 to move linearly inside the cylinder 1.

[0033] Furthermore, at least one set of guide grooves 7 are provided on the inner wall of the cylinder 1, and at least one set of guide protrusions 8 are connected to the outer wall of the connecting part 22. The guide protrusions 8 are placed in the guide grooves 7 and slide along the guide grooves 7. The cooperation between the guide grooves 7 and the guide protrusions 8 constrains the connecting part 22, preventing the connecting part 22 from rotating while the screwing part 21 rotates, thus maintaining its linear state during movement. This facilitates the opening slit 4 remaining parallel to the reinforcing rib b when the two clamping petals 3 are fed into the hollow brick a.

[0034] Furthermore, one end of the screwing part 21 has a rotating groove 23 with a "T"-shaped cross-section, and one end of the connecting part 22 is fixed with a connector 24 with a "T"-shaped cross-section. The connector 24 is fitted into the rotating groove 23 to form a structure that can rotate relative to each other. Through the design of the rotating groove 23 and the connector 24, a structure that can rotate relative to each other can be formed, thereby preventing the connecting part 22 from rotating synchronously with the screwing part 21 during rotation.

[0035] In some embodiments, the portion of the drive rod 2 located outside the cylinder 1 is connected to a screw ring 9. The design of the screw ring 9 can increase the friction between the hand and the screwing part 21, avoid slippage during screwing, and make it more labor-saving.

[0036] In some embodiments, the clamping opening 5 is located in the middle of the opening slit 4, forming a guide channel at the front and a space at the rear for the two clamping petals 3 to retract inward. This design allows the reinforcing rib b to enter the opening slit 4 more smoothly, reducing the difficulty of aligning the reinforcing rib b with the opening slit 4, especially in construction scenarios within hollow bricks a, thus improving installation efficiency. The space at the rear provides ample room for the two clamping petals 3 to retract inward, ensuring that the two clamping petals 3 can fully retract, thereby allowing the clamping opening 5 to form a reliable clamping force on the reinforcing bar.

[0037] refer to Figures 3 to 6 This utility model also proposes a green building exterior wall insulation wall, which includes an insulation wall formed by a number of hollow bricks a, with a perforation g on one side of the hollow bricks a, and a vertically fixed reinforcing rib b in the insulation inner wall. The bottom of the reinforcing rib b is fixed to the foundation and extends upward, penetrating the center of the vertically stacked hollow bricks a.

[0038] It also includes the aforementioned insulated wall panel connector c and insulated board d. One end of the insulated wall panel connector c freely passes through the through hole g, and is positioned in its current position by the contraction and clamping of the reinforcing rib b by the two clamping petals 3. The insulated board d has several stepped holes e inside. The inner wall of the insulated board d passes through the cylinder 1 of the insulated wall panel connector c through the stepped holes e, and is in close contact with the outer wall of the hollow brick a. Subsequently, it is connected to the other end of the drive rod 2 by a threaded connection through the pressure cap 6, positioning the insulated board d between the hollow brick a and the pressure cap 6. A finishing layer f is fixed to the outer wall of the insulated board d, thus forming a green building exterior wall insulation structure.

[0039] The reinforcing rib b is fixed to the foundation at its bottom and vertically penetrates the center of several hollow bricks a. Combined with the clamping and positioning of the reinforcing rib b by the insulation wall panel connector c, a vertical structural force-bearing system is formed, which can significantly improve the rigidity of the insulation wall. The insulation board d is tightly fixed between the hollow bricks a and the clamping cap 6 via a threaded connection between the clamping cap 6 and the drive rod 2, forming a rigid connection with the wall, thereby preventing problems such as the insulation board d falling off during long-term use.

[0040] In some embodiments, insulating and / or sound-insulating mortar h is poured into the hollow bricks a. After the mortar is poured, the insulating inner wall formed by several hollow bricks a can become a whole, further enhancing its compressive and flexural strength, and improving the overall structural stability and durability. The filling of the insulating mortar can enhance the thermal insulation capacity of the hollow bricks a, thereby improving the overall thermal insulation and energy-saving effect of the building. The filling of the sound-insulating mortar can absorb and block the transmission of sound, creating a quieter space for residents or users, such as reducing interference from external traffic noise and neighborhood noise.

[0041] In some embodiments, the outer end of the retaining cap 6 is flush with the outer surface of the insulation board d, or placed inside the outer surface of the insulation board d. This avoids bulging of the finishing layer f due to the protrusion of the retaining cap 6, and allows the inner wall of the finishing layer f to fit against the outer wall of the insulation board d.

[0042] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
