Description

Technical Field

[0001] This utility model belongs to the field of rock wool formwork, specifically relating to a decorative rock wool formwork that does not require disassembly. Background Technology

[0002] The cast-in-place concrete construction system, which uses cast-in-place concrete composite external insulation rock wool without the need for formwork removal, is suitable for external wall insulation projects of civil buildings in extremely cold and cold regions. It can improve the thermal insulation capacity of the exterior walls of civil buildings, reduce the efficiency of indoor and outdoor temperature diffusion, and help reduce energy consumption for cooling and heating.

[0003] Decorative rock wool formwork is a type of formwork that uses external insulation rock wool as the outer formwork and internal interior finish as a permanent formwork, or traditional steel or aluminum formwork as a removable inner formwork. These are connected by tie bolts to form a pouring cavity, where concrete is poured. Once the concrete has hardened, only the removable inner formwork is removed. The external insulation rock wool formwork forms a permanent formwork with the wall, and a thin metal panel is pasted on the outside of the rock wool layer as a decorative surface layer.

[0004] To prevent the rock wool layer and the thin metal panel with a certain weight from falling off, threaded tail bolts are currently used to connect the thin metal panel and insert it through the rock wool layer into the cast-in-place concrete layer. Since the threaded tail bolts are installed in place before pouring, the concrete pouring generates a certain impact. Because the rock wool layer is relatively loose, it cannot provide good support, causing the thin metal panel to bear the cantilever force. This causes the thin metal panel to deform at the connection point of the threaded tail bolts, resulting in a decrease in the flatness of the thin metal panel and a deterioration in appearance. If the thin metal panel is torn, it may also lead to corrosion and water ingress into the rock wool layer, affecting the thermal insulation performance. Utility Model Content

[0005] In order to solve the problems existing in the prior art, this utility model provides a decorative rock wool non-removable template, which can enhance the support of the threaded tail screw, improve the final flatness of the thin metal panel, enhance the appearance of the exterior wall, and help protect the thermal insulation performance of the wall.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] The decorative rock wool non-removable template includes a thin metal panel, a rock wool layer, and a crack-resistant fiberglass cloth layer arranged sequentially from the outside to the inside. The back of the thin metal panel is bonded to the rock wool layer and is provided with multiple fixing sleeves at intervals. The cantilevered end of the fixing sleeve is detachably connected to a threaded tail screw by means of threads. The tail end of the threaded tail screw extends beyond the rock wool layer and the crack-resistant fiberglass cloth layer. A steel mesh layer is added outside the crack-resistant fiberglass cloth layer. The steel mesh is fixedly connected to the rock wool layer and the crack-resistant fiberglass cloth layer. The cantilevered end of the threaded tail screw is tied and fixed to the steel mesh.

[0008] The steel mesh is fixedly connected to the rock wool layer and the crack-resistant fiberglass cloth layer by means of fixing pins. The fixing pins have an n-shaped structure, and the two cantilevered pins of the fixing pins are provided with barbs formed by bending. The closed end of the fixing pin straddles the intersection of the warp and weft threads of the steel mesh.

[0009] A C-shaped steel sheet is welded and fixed to the back of the thin metal panel. The cross-section of the C-shaped steel sheet is bow-shaped. A through hole is provided in the middle recessed area of ​​the C-shaped steel sheet, and a fixing bolt is also provided. The fixing bolt passes through the through hole and is threadedly connected to the fixing sleeve. The fixing bolt and the fixing sleeve are clamped with the C-shaped steel sheet to form a fixed connection.

[0010] The threaded tail screw has an L-shaped structure. The straight end of the threaded tail screw is provided with a thread that is threaded to connect with the fixed screw sleeve. The hook end of the threaded tail screw is an overhanging end.

[0011] The rock wool layer has a tongue and groove joint at the edge of the thin metal panel, and the tongue and groove joint has a sealing edge with a concave and convex fit. The decorative rock wool templates are arranged in a matrix and overlap to form an outer template. The edges of adjacent decorative rock wool templates have concave filling seams. The thin metal panel has a semi-circular arc-shaped sealing flange at the lower tongue and groove joint and a quarter-circular arc-shaped support flange at the upper tongue and groove joint.

[0012] The beneficial effects of this utility model are:

[0013] This invention adds a steel mesh and forms a second support surface parallel to the thin metal panel by fixing the steel mesh to the rock wool layer and the crack-resistant fiberglass cloth layer. The threaded tail bolts are then fixed to the steel mesh by binding, thereby resisting the impact of the cast refractory material on the threaded tail bolts during pouring, enhancing the support of the threaded tail bolts, improving the final flatness of the thin metal panel, improving the appearance of the exterior wall, and helping to protect the thermal insulation performance of the wall.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1 As shown, this utility model is a decorative rock wool non-removable template, including a thin metal panel 1, a rock wool layer 2, and a crack-resistant fiberglass cloth layer 3 arranged sequentially from the outside to the inside. The back of the thin metal panel 1 is bonded to the rock wool layer 2 and is provided with multiple fixing sleeves 4 at intervals. The cantilever end of the fixing sleeve 4 is detachably connected to a threaded tail screw 5 by means of threads. The tail end of the threaded tail screw 5 extends outside the rock wool layer 2 and the crack-resistant fiberglass cloth layer 3. A steel mesh layer 6 is added outside the crack-resistant fiberglass cloth layer 3. The steel mesh is fixedly connected to the rock wool layer 2 and the crack-resistant fiberglass cloth layer 3. The cantilever end of the threaded tail screw 5 is tied and fixed to the steel mesh.

[0021] This invention adds a steel mesh and forms a second support surface parallel to the thin metal panel 1 by fixing the steel mesh to the rock wool layer 2 and the crack-resistant fiberglass cloth layer 3. The threaded tail bolt 5 is fixed to the steel mesh by binding, thereby resisting the impact of the cast refractory on the threaded tail bolt 5 during pouring, enhancing the support of the threaded tail bolt 5, improving the final flatness of the thin metal panel 1, improving the appearance of the exterior wall, and helping to protect the thermal insulation performance of the wall.

[0022] Furthermore, such as Figure 1 and Figure 3 As shown, the steel mesh is fixedly connected to the rock wool layer 2 and the crack-resistant fiberglass cloth layer 3 by means of fixing pins 7. The fixing pins 7 have an n-shaped structure, and the two cantilevered pins of the fixing pins 7 are provided with barbs formed by bending. The closed end of the fixing pins 7 straddles the intersection of the warp and weft threads of the steel mesh.

[0023] The length of the fixing pin 7 used in this invention is at least three-quarters of the thickness of the rock wool layer 2, so as to be as close as possible to the thin metal panel 1 coated with adhesive. Due to the penetration of the adhesive, the rock wool layer 2 in this part is dense and stable, thereby improving the pull-out force of the barbs of the fixing pin 7, ensuring that the steel mesh is fixed on the outside of the crack-resistant fiberglass cloth layer 3. The crack-resistant fiberglass cloth layer 3 is also bonded with adhesive, and the overflowing adhesive also plays a certain auxiliary bonding role for the metal mesh.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, a C-shaped steel sheet 8 is welded and fixed to the back of the thin metal panel 1. The cross-section of the C-shaped steel sheet 8 is bow-shaped. A through hole is provided in the middle recessed area of ​​the C-shaped steel sheet 8, and a fixing bolt 9 is also provided. The fixing bolt 9 passes through the through hole and is threadedly connected to the fixing sleeve 4. The fixing bolt 9, the fixing sleeve 4, and the C-shaped steel sheet 8 are clamped together to form a fixed connection.

[0025] The C-shaped steel sheet 8 is welded and fixed to the thin metal panel 1. The C-shaped steel sheet 8 enhances the structural strength of the thin metal panel 1 and forcibly ensures the flatness of the thin metal panel 1. At the same time, the C-shaped steel sheet 8 can also be set along the vertical direction of the thin metal panel 1 (in this embodiment...). Figure 3 (Not shown in the image), further dispersing the force on the thin metal panel 1, Figure 3 It is set along the horizontal direction of the thin metal panel 1.

[0026] Furthermore, such as Figure 2 As shown, the threaded tail screw 5 has an L-shaped structure. The straight end of the threaded tail screw 5 is provided with a thread that is threaded to the fixed screw sleeve 4. The hook end of the threaded tail screw 5 is an overhanging end.

[0027] The hook end of the threaded tail screw 5 extends into the cast-in-place layer. After the cast-in-place layer solidifies, it can pull out the wall and stabilize the rock wool layer 2. At the same time, the thin metal panel 1 and the steel mesh help stabilize the shape of the rock wool layer 2 and prevent the rock wool layer 2 from collapsing or shifting after being suspended for a long time.

[0028] Furthermore, the rock wool layer 2 has a strip-shaped tongue and groove joint 10 at the edge of the thin metal panel 1, and the tongue and groove joint has a sealing edge 11 with a concave and convex fit. The decorative rock wool templates are arranged in a matrix and overlap to form an outer template. The edges of adjacent decorative rock wool templates have concave filling seams. The thin metal panel 1 has a semi-circular sealing flange 12 at the lower tongue and groove joint, and the thin metal panel 1 has a quarter-circular supporting flange 13 at the upper tongue and groove joint.

[0029] like Figure 1 and Figure 4 As shown, the filling joint formed by the tongue and groove edge is filled with neutral silicone weather-resistant sealant after the wall is poured and initially set. The sealing flange 12 and the supporting flange 13 overlap and fit together, as shown. Figure 4 The right figure shows a schematic diagram of the disassembled state, where the sealing flange 12 rests on the supporting flange 13, as shown. Figure 4As shown in the left figure, after filling with neutral silicone weather-resistant adhesive, if the adhesive cracks and detaches due to long-term use or misalignment caused by downward pressure on the thin metal panel 1, the sealing flange 12 and the supporting flange 13 overlap. This allows the sealing flange 12 to guide water flow, preventing it from entering the tongue and groove joint. A sealing flange 12 can also be provided on one side of the thin metal panel 1 to mate with adjacent thin metal panels 1. Furthermore, to prevent cracking of the neutral silicone weather-resistant adhesive, through holes can be provided at the overlap between the sealing flange 12 and the supporting flange 13, thereby enhancing the gripping force of the sealing flange 12 on the adhesive.
