Description

Technical Field

[0001] The present invention relates to the technical field of exterior wall thermal insulation structures, and particularly to a composite thermal insulation and demountable formwork for building exterior walls. Background Art

[0002] With the improvement of building energy conservation requirements, thermal insulation exterior walls have become a standard configuration for modern buildings. Traditional exterior wall thermal insulation methods often use materials such as external thermal insulation boards and steel wire meshes. However, these materials are easily affected by the external environment, and the construction process is cumbersome. The thermal insulation demountable formwork combines the formwork with the thermal insulation layer, reducing the construction period and the waste generated during form removal, improving the construction efficiency, and saving manpower and material resources.

[0003] Among them, in order to ensure that the subsequent thermal insulation demountable formwork can be firmly combined with the base wall, corresponding internal threaded cylinders need to be inserted into the thermal insulation demountable formwork to facilitate the subsequent use of fixing steel nails to pass through them and insert into the base wall to achieve the fixation of the thermal insulation demountable formwork and the base wall. When combining the internal threaded cylinders during the production stage of the thermal insulation demountable formwork, although a certain fixing force can be generated on the surface of the internal threaded cylinders by using bonding substances such as cement, due to the smooth surface of the internal threaded cylinders under normal circumstances, when they are inserted into the unfixed thermal insulation demountable formwork, it is difficult to generate sufficient physical or chemical bonding forces with the surrounding materials, which easily leads to the detachment of the internal threaded cylinders from the materials when subsequent pressure or load is applied. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a composite thermal insulation and demountable formwork for building exterior walls to solve the problem of insufficient bonding force between the internal threaded cylinders added in the thermal insulation demountable formwork for connecting the fixing steel nails and the materials of the thermal insulation demountable formwork as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A composite thermal insulation and demountable formwork for building exterior walls, including a base wall, a thermal insulation demountable module is arranged on one side of the base wall, a reserved positioning component is installed on the thermal insulation demountable module, and a fixing steel nail extending into the interior of the base wall is threadedly connected inside the reserved positioning component; The reserved positioning component includes a positioning cylinder inserted into it during the production of the thermal insulation demountable module. A sealing structure for closing the tail end opening is connected to the tail end of the positioning cylinder when it is directly inserted into the unfixed thermal insulation demountable module made of materials. A deformation structure for increasing external protrusions is installed on the positioning cylinder when a direct tensile force is applied.

[0006] Preferably, the thermal insulation demountable module includes a thermal insulation core material arranged in the middle. Cement mortar layers are arranged on both sides of the thermal insulation core material. A bonding strengthening layer is arranged on the side of the cement mortar layer away from the thermal insulation core material, and a fiberglass mesh cloth is sandwiched between the bonding strengthening layer and the cement mortar layer.

[0007] Preferably, the fiberglass mesh is arranged in a double layer and is of the alkali-resistant type with a weight of 160 g / m 2 . The length of the positioning cylinder is the same as the thickness of the thermal insulation and non-removable module. When the two are combined, the tail end of the positioning cylinder is in the same plane as the rear side of the thermal insulation and non-removable module.

[0008] Preferably, the positioning cylinder is composed of an internal threaded cylinder passing through the thermal insulation core material and a receiving cylinder connected to the front end of the internal threaded cylinder, wherein the cross-section of the groove of the receiving cylinder is T-shaped.

[0009] Preferably, at least two grooves are formed on the outer surface of the internal threaded cylinder; The deformation structure includes a straight plate block rotatably installed in the groove. A support plate is rotatably installed on the straight plate block. A pull rod is rotatably installed on the support plate and passes through the internal threaded cylinder from the rear to the front along the groove and extends into the receiving cylinder. Widening strips are installed on both sides of the straight plate block.

[0010] Preferably, a notch is formed on the straight plate block for coinciding with the support plate when the straight plate block is horizontally arranged.

[0011] Preferably, when the straight plate block and the support plate are horizontally arranged, the sum of their thicknesses and the thickness of the pull rod fits the depth of the side of the groove. When the straight plate block is horizontally arranged, the bottom of the widening strip fits the bottom wall of the groove.

[0012] Preferably, the sealing structure is composed of a threaded ring detachably connected to the inside of the internal threaded cylinder and a tapered head integrally connected to the tail end of the threaded ring. A cross slot is formed on the front side of the tapered head.

[0013] By means of the above technical solutions, the present invention provides a composite thermal insulation and non-removable formwork for building exterior walls, which has at least the following beneficial effects: 1. While meeting the thermal insulation requirements of the building exterior wall, the composite thermal insulation and non-removable formwork for building exterior walls effectively realizes the integration of building thermal insulation and structure, and there is no need for additional disassembly.

[0014] 2. After the reserved positioning components are combined and inserted during the customization stage of the thermal insulation and non-removable module, the straight plate block and the support plate that overlap vertically and are horizontally arranged can be adjusted to an inclined state. A triangular protrusion is formed between them and the bottom wall of the groove in the internal threaded cylinder. Together with the widening strip, the side width of the straight plate block is increased, and they are embedded in the thermal insulation and non-removable module together to form a mechanical interlock, effectively preventing the internal threaded cylinder from rotating or loosening when stressed.

[0015] 3. During the stage of combining the positioning cylinder and the heat-insulating and formwork-removing module of the building exterior wall composite heat-insulating formwork, the detachable plugging structure can be used to plug the end opening of the positioning cylinder, effectively preventing the unfixed materials in the heat-insulating and formwork-removing module from adhering to the internal thread of the positioning cylinder and ensuring the integrity of its thread.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0019] Embodiment 1 As shown in the figure, 1- Figure 5As shown in the figure, this embodiment proposes a composite thermal insulation and non-removable formwork for building exterior walls, which can achieve the integration of building thermal insulation and structure while meeting the thermal insulation requirements of building exterior walls, without the need for additional disassembly. The composite thermal insulation and non-removable formwork for building exterior walls has a base wall 1 and a thermal insulation and non-removable module 2 arranged on one side of the base wall 1, and the two are firmly combined through a reserved positioning component 3 installed on the thermal insulation and non-removable module 2 and additional fixed steel nails 4, integrating the thermal insulation and non-removable module 2 and the base wall 1 into one. Subsequently, a surface glue mortar layer can be directly applied to the outer surface of the thermal insulation and non-removable module 2, and a decorative layer can be pasted, without the need for additional disassembly, reducing the processes of formwork removal, cleaning and repair, significantly shortening the construction period, and the thermal insulation and non-removable module 2 is closely combined with the base wall 1, improving the overall stability and seismic performance of the wall.

[0020] Continuing from the above, in order to accelerate the construction progress, the thermal insulation and non-removable module 2 is usually customized in advance according to building and construction requirements, and in order to facilitate the subsequent combination with the fixed steel nails 4, generally during the manufacturing process, the reserved positioning component 3 needs to be inserted inside. Among them, due to the relatively smooth surface of the reserved positioning component 3 under normal circumstances, the frictional force between it and the thermal insulation and non-removable module 2 is small. Therefore, the combination of the two lacks stability and there is not enough frictional force to support, which may cause the reserved positioning component 3 to separate from the thermal insulation and non-removable module 2. In order to effectively solve this problem, as Figures 1-4As shown in the figure, the reserved positioning component 3 in this embodiment includes a positioning cylinder 301 inserted into the thermal insulation and non-detachable module 2 during its production. A plugging structure 302 is connected to the tail end of the positioning cylinder 301, which is used to seal the tail end opening when the positioning cylinder 301 is directly inserted into the thermal insulation and non-detachable module 2 with unfrozen material. During the process of inserting the reserved positioning component 3 into the interior of the thermal insulation and non-detachable module 2, the unfrozen material in the thermal insulation and non-detachable module 2 may enter the positioning cylinder 301 and damage the internal thread pattern. The positioning cylinder 301 is composed of an internal thread cylinder 3011 passing through the thermal insulation core material 201 and a receiving cylinder 3012 connected to the front end of the internal thread cylinder 3011. The groove-shaped cross-section of the receiving cylinder 3012 is T-shaped, mainly used to adapt to the shape of the fixing steel nail 4. At least two grooves are provided on the outer surface of the internal thread cylinder 3011. A deformation structure 303 is installed on the positioning cylinder 301, which can increase the external protrusion when a direct tensile force is applied. The deformation structure 303 includes a straight strip plate 3031 rotatably installed in the groove. A support plate 3032 is rotatably installed on the straight strip plate 3031. A pull rod 3033 is rotatably installed on the support plate 3032 and passes through the internal thread cylinder 3011 from the rear to the front along the groove and extends into the interior of the receiving cylinder 3012. Widening strips 3034 are installed on both sides of the straight strip plate 3031. During the stage of customizing the thermal insulation and non-detachable module 2, the reserved positioning component 3 is inserted into the set position, so that the front end plane of the receiving cylinder 3012 is in the same plane as the front side plane of the thermal insulation and non-detachable module 2. After that, by applying a pulling force from the rear to the front on the pull rod 3033, the horizontally arranged straight strip plate 3031 and the support plate 3032 are gradually adjusted to an inclined state. A triangle is formed between them and the bottom wall of the groove of the internal thread cylinder 3011, which is used to increase the protrusion on the smooth surface of the internal thread cylinder 3011, further improving the biting force between the internal thread cylinder 3011 and the thermal insulation and non-detachable module 2. And this protrusion can be embedded in the gradually solidifying thermal insulation and non-detachable module 2 to form a mechanical interlock, preventing the internal thread cylinder 3011 from loosening and detaching from the thermal insulation and non-detachable module 2 when subjected to a forward pulling force. In addition, the widening strips 3034 are used to increase the side width of the straight strip plate 3031, also increasing the biting force with the thermal insulation and non-detachable module 2 to prevent the internal thread cylinder 3011 from rotating or loosening when stressed.

[0021] In addition, when the straight strip plate 3031 is horizontally arranged, the support plate 3032 coincides with the slot opened on the straight strip plate 3031, which can save the occupied space. And when the straight strip plate 3031 and the support plate 3032 are horizontally arranged, the sum of their thicknesses and the thickness of the pull rod 3033 fits the depth of the side of the groove, and the bottom of the widening strip 3034 fits the bottom wall of the groove, ensuring that the horizontally arranged straight strip plate 3031 does not form a protrusion outside the internal thread cylinder 3011, which is convenient for directly inserting into the unfrozen thermal insulation and non-detachable module 2.

[0022] More specifically, the heat-insulating non-removable module 2 includes a heat-insulating core material 201 disposed in the middle. The heat-insulating core material 201 is 30 mm polystyrene particle thermal insulation mortar with a combustion performance grade of A. On both sides of the heat-insulating core material 201, there are cement mortar layers 202, which can increase the overall strength and stability of the module. On the side of the cement mortar layer 202 away from the heat-insulating core material 201, there is an adhesion strengthening layer 203. A fiberglass mesh cloth 204 is sandwiched between the adhesion strengthening layer 203 and the cement mortar layer 202. The fiberglass mesh cloth 204 is arranged in a double layer and has a weight of 160 g / m 2 of alkali-resistant type. The adhesion strengthening layer 203 is used to improve the adhesion between the thermal insulation mortar and the cement mortar layer 202 and the fiberglass mesh cloth 204, enhance the integrity and reliability of the entire thermal insulation system, prevent the phenomenon of peeling or delamination, and cooperate with the fiberglass mesh cloth 204 to effectively enhance the crack resistance of the thermal insulation layer, avoid cracks caused by factors such as temperature change, humidity fluctuation or building settlement. The fiberglass mesh cloth 204 can evenly disperse stress, prevent crack propagation, and ensure the long-term stability of the thermal insulation layer. Moreover, the polystyrene particle thermal insulation mortar and the cement mortar layer 202 have certain waterproof properties, which can effectively prevent water from penetrating into the thermal insulation layer and avoid the decrease in thermal insulation performance caused by water accumulation; the combination of the cement mortar layer 202 and the fiberglass mesh cloth 204 makes the thermal insulation system have strong freeze-thaw resistance.

[0023] Embodiment 2 Under normal circumstances, during the stage of customizing the heat-insulating non-removable module 2, when inserting the internal thread cylinder 3011, the material that has not fully solidified inside the heat-insulating non-removable module 2 will enter the inside of the internal thread cylinder 3011, thereby damaging the internal thread therein and affecting the subsequent combination effect with the fixing steel nail 4. In order to effectively solve this problem, as Figure 2 、 Figure 3 and Figure 5As shown in the figure, by making the length of the positioning cylinder 301 consistent with the thickness of the heat-insulating and non-removable module 2, and when the two are combined, the tail end of the positioning cylinder 301 and the rear side of the heat-insulating and non-removable module 2 are in the same plane. The sealing structure 302 is composed of a threaded ring 3021 detachably connected inside the internal threaded cylinder 3011 and a tapered head 3022 integrally connected to the tail end of the threaded ring 3021. A cross slot 3023 is provided on the front side of the tapered head 3022. Before the positioning cylinder 301 and the heat-insulating and non-removable module 2 are combined, the sealing structure 302 is detachably connected to the end of the internal threaded cylinder 3011 to block the end opening thereof. In addition, with the cooperation of its tapered head 3022, it is convenient for the positioning cylinder 301 to be inserted into the unfixed heat-insulating and non-removable module 2, and at the same time, it avoids the unfixed material adhering to the internal thread of the internal threaded cylinder 3011. After the positioning cylinder 301 and the heat-insulating and non-removable module 2 are combined, insert a tool into the cross slot 3023 externally and drive the tapered head 3022 to rotate in the set direction, so that the threaded ring 3021 is separated from the internal threaded cylinder 3011, and then the sealing structure 302 can be removed to facilitate the subsequent assembly of the fixing steel nail 4.

[0024] As mentioned above, the above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
