Description

Technical Field

[0001] This utility model relates to the field of construction template technology, and in particular to a non-removable composite thermal insulation template for building exterior walls. Background Technology

[0002] Existing thermal insulation templates, as shown in the patent application number CN201520537941.9, include a precast concrete exterior wall template, an insulation layer, a long screw, an inner template, and a nut. The precast concrete exterior wall template and the inner template are connected by the long screw and the nut. Concrete is poured between the precast concrete exterior wall template and the inner template to form the exterior wall of the building.

[0003] In the above-mentioned insulation process, the end of the long screw and the nut protrude from the inside of the insulation, which makes it inconvenient to directly paint and decorate the inside of the insulation. It is necessary to remove the nut and use a cutting machine to cut off the protruding end of the long screw. Only after the inside of the insulation is flat can it be painted. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of existing thermal insulation templates, this utility model proposes a non-removable composite thermal insulation template for building exterior walls, which has a smoother inner side, making it easier for subsequent painting and decoration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-removable composite thermal insulation template for building exterior walls includes a composite outer template, a first embedded part, a tensile pipe, a second embedded part, a composite inner template, and bolts. The first embedded part and the second embedded part are respectively embedded in the composite outer template and the composite inner template.

[0007] The side of the second embedded part away from the first embedded part is flush with the inner side of the composite inner template. The second embedded part has a through mounting hole adapted to the bolt. The end of the mounting hole near the first embedded part is provided with a conical slot. The flared end of the conical slot faces the composite outer template. The other end of the mounting hole is provided with a receiving groove.

[0008] One end of the tensile tube is locked to the first embedded part, and the other end of the tensile tube is tapered. The other end of the tensile tube is inserted into the tapered slot and fits against the wall of the tapered slot. The bolt includes a stud and a head. The head is embedded in the receiving groove. The side of the head away from the first embedded part is flush with the inner side of the composite inner template. The stud is screwed into the end of the tensile tube through the mounting hole.

[0009] With the above settings, firstly, the inner side of the non-removable composite insulation template is smoother, making it easier to paint; secondly, the tensile tube is hollow, improving the insulation effect of the exterior wall; and thirdly, the conical slot fits snugly with the end of the tensile tube, preventing water from seeping into the installation hole.

[0010] Furthermore, the conical slot has an annular groove along its circumferential direction at the constricted end, and the end of the tensile tube has an annular protrusion that matches the annular groove along its circumferential direction. The annular protrusion is located in the annular groove, and the outer periphery of the annular protrusion fits against the groove wall of the annular groove. The non-removable composite thermal insulation template also includes a first sealing ring located in the annular groove. The first sealing ring is squeezed by the annular protrusion and is at least partially embedded in the mounting hole.

[0011] The above settings further enhance waterproofing.

[0012] Furthermore, the non-removable composite insulation template also includes a second sealing ring set in the receiving groove, the second sealing ring being squeezed by the head of the bolt and at least partially embedded in the mounting hole.

[0013] The above settings further enhance waterproofing.

[0014] Furthermore, the first embedded part is provided with an internal thread groove, and the end of the tensile tube is screwed into the internal thread groove.

[0015] The above setup facilitates locking the end of the tensile tube into the first embedded part.

[0016] Furthermore, the outer periphery of the first embedded part is fixedly connected with several first anti-pull-out nails.

[0017] The above settings improve the pull-out resistance of the first embedded part.

[0018] Furthermore, the outer periphery of the second embedded part is fixedly connected with several second anti-pull-out nails.

[0019] The above settings improve the pull-out resistance of the second embedded part.

[0020] Furthermore, the composite outer formwork includes a first concrete layer and a first insulation layer disposed inside the first concrete layer. A first embedded part is embedded in the first concrete layer. A first clearance hole is provided on the first insulation layer. The tensile tube is locked onto the first embedded part through the first clearance hole.

[0021] Furthermore, the composite inner formwork includes a second concrete layer and a second insulation layer disposed outside the second concrete layer. A second embedded part is embedded in the second concrete layer. A second clearance hole is provided on the second insulation layer. The tensile tube is locked onto the second embedded part through the second clearance hole. Attached Figure Description

[0023] Figure 2 for Figure 1 Enlarged view of point A. Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] like Figures 1 to 2 A non-removable composite thermal insulation template for building exterior walls includes a composite outer template 3, a first embedded part 4, a tensile pipe 5, a second embedded part 6, a composite inner template 7, and bolts 8. The first embedded part 4 and the second embedded part 6 are respectively embedded in the composite outer template 3 and the composite inner template 7.

[0026] The side of the second embedded part 6 away from the first embedded part 4 is flush with the inner side of the composite inner template 7. The second embedded part 6 is provided with a mounting hole 9 that is compatible with the bolt 8. The end of the mounting hole 9 near the first embedded part 4 is provided with a conical slot 10. The flared end of the conical slot 10 faces the composite outer template 3. The other end of the mounting hole 9 is provided with a receiving groove 11.

[0027] One end of the tensile tube 5 is locked onto the first embedded part 4, and the other end of the tensile tube 5 is tapered. The other end of the tensile tube 5 is inserted into the tapered slot 10 and fits against the groove wall of the tapered slot 10. The bolt 8 includes a stud part 81 and a head 82. The head is embedded in the receiving groove 11. The side of the head away from the first embedded part 4 is flush with the inner side of the composite inner template 7. The stud part is screwed into the end of the tensile tube 5 through the mounting hole 9.

[0028] With the above settings, firstly, the inner side of the non-removable composite insulation template is smoother, making it easier to paint; secondly, the tensile tube 5 is hollow, improving the insulation effect of the exterior wall; and thirdly, the conical slot 10 fits snugly with the end of the tensile tube 5, preventing water from seeping into the installation hole 9.

[0029] When pouring the exterior wall of the building, the composite outer formwork 3 is first vertically installed on the ground formwork. The composite outer formwork 3 can refer to existing thermal insulation formwork, which is prefabricated in the factory and transported to the construction site for use. One end of the tensile tube 5 is vertically locked to the first embedded part 4 of the composite outer formwork 3. The tensile tube 5 has a hollow tubular structure to increase thermal insulation. In addition, a material with high strength and poor thermal conductivity, such as carbon fiber, can be used to further increase thermal resistance, thereby improving thermal insulation. The composite inner formwork 7 is placed vertically on the ground formwork. The conical slot 10 on the second embedded part 6 is aligned with the conical end of the tensile tube 5, so that the conical end of the tensile tube 5 can be smoothly inserted into the conical slot 10. The end of the tensile tube 5 is conical and fits against the conical slot 10. The mounting holes 9 are used to create a larger contact area between the tensile tube 5 and the second embedded part 6, improving waterproofing and preventing moisture from penetrating into the inner side of the composite inner formwork 7. The bolts 8 are passed through the mounting holes 9 and tightened at the end of the tensile tube 5, locking the end of the tensile tube 5 into the second embedded part 6. The side of the bolt head away from the first embedded part 4 is flush with the inner side of the composite inner formwork 7, making the inner side of the assembled non-removable composite insulation formwork relatively flat. Concrete is poured between the composite inner formwork 7 and the composite outer formwork 3. After the concrete has cured, the non-removable composite insulation formwork does not need to be removed. The non-removable composite insulation formwork is part of the exterior wall, improving the insulation performance of the exterior wall. Since the inner side is relatively flat, the interior of the exterior wall can be directly painted and decorated.

[0030] As one implementation, the conical slot 10 has an annular groove 12 circumferentially arranged at the constricted end, and the end of the tensile tube 5 has an annular protrusion 13 adapted to the annular groove 12 circumferentially arranged at the end. The annular protrusion 13 is arranged in the annular groove 12, and the outer periphery of the annular protrusion 13 fits against the groove wall of the annular groove 12. The non-removable composite thermal insulation template also includes a first sealing ring 14 arranged in the annular groove 12. The first sealing ring 14 is squeezed by the annular protrusion 13 and is at least partially embedded in the mounting hole 9.

[0031] The above settings further enhance waterproofing.

[0032] The tapered slot 10 has an annular groove 12 along its circumference at the end away from the first embedded part 4. The first sealing ring 14 is pre-embedded in the annular groove 12. Before installing the composite inner template 7, the bolt 8 passes through the mounting hole 9 and the first sealing ring 14. Then, the stud part of the bolt 8 is aligned with the tapered end of the tensile tube 5. The bolt 8 is rotated, and the stud part of the bolt 8 is slowly screwed into the tapered end of the tensile tube 5. The tapered end of the tensile tube 5 slowly enters the tapered slot 10. Finally, the end of the tensile tube 5 fits into the tapered slot 10, and the annular protrusion 13 enters the annular groove 12 and squeezes the first sealing ring 14. The first sealing ring 14 is made of rubber and is embedded in the mounting hole 9 after being squeezed by the annular protrusion 13, thus sealing the mounting hole 9.

[0033] As one implementation, the non-removable composite insulation template also includes a second sealing ring 15 disposed in the receiving groove 11. The second sealing ring 15 is pressed by the head of the bolt 8 and is at least partially embedded in the mounting hole 9.

[0034] The above settings further enhance waterproofing.

[0035] As one implementation method, the first embedded part 4 is provided with an internal thread groove 16, and the end of the tensile tube 5 is screwed into the internal thread groove 16.

[0036] The above setup facilitates locking the end of the tensile tube 5 into the first embedded part 4.

[0037] As one implementation method, the outer periphery of the first embedded part 4 is fixedly connected with several first anti-pull-out nails 17.

[0038] The above settings improve the pull-out resistance of the first embedded part 4.

[0039] As one implementation method, the outer periphery of the second embedded part 6 is fixedly connected with several second anti-pull-out nails 18.

[0040] The above settings improve the pull-out resistance of the second embedded part 6.

[0041] The first anti-pull-out nail 17 and the second anti-pull-out nail 18 of this application are specifically mushroom-shaped and are uniformly welded to the first embedded part 4 and the second embedded part 6, respectively, so as to increase the contact area between the first embedded part 4 and the composite outer template 3, and the contact area between the second embedded part 6 and the composite inner template 7, thereby improving the stability of the first embedded part 4 and the second embedded part 6.

[0042] As one implementation method, the composite outer formwork 3 includes a first concrete layer 31 and a first insulation layer 32 disposed inside the first concrete layer 31. A first embedded part 4 is embedded in the first concrete layer 31. A first clearance hole is provided on the first insulation layer 32. The tensile tube 5 is locked onto the first embedded part 4 through the first clearance hole.

[0043] As one implementation, the composite inner formwork 7 includes a second concrete layer 71 and a second insulation layer 72 disposed outside the second concrete layer 71. A second embedded part 6 is embedded in the second concrete layer 71. A second clearance hole is provided on the second insulation layer 72. The tensile tube 5 is locked onto the second embedded part 6 through the second clearance hole.

[0044] As one implementation method, the first insulation layer 32 and the second insulation layer 72 can be made of foamed materials.

[0045] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
