Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of external wall insulation structure, in particular to a composite insulation formwork for building external wall. BACKGROUND

[0002] With the improvement of building energy saving requirements, the insulation external wall becomes the standard configuration of modern buildings. Traditional external wall insulation method often uses external insulation board, steel mesh and other materials, but these materials are easily affected by the external environment, and the construction process is complicated. The insulation formwork reduces the construction period and the demolition of waste, which can improve the construction efficiency and save manpower and material resources.

[0003] Among them, in order to ensure that the subsequent insulation formwork can be combined with the base wall firmly, the corresponding internal threaded cylinder needs to be inserted in the insulation formwork, so that the subsequent fixed steel nails can pass through it and be inserted into the base wall, realizing the fixation of the insulation formwork and the base wall. While combining the internal threaded cylinder in the production stage of the insulation formwork, the internal threaded cylinder surface can generate a certain fixation force by using the cement binder, but since the internal threaded cylinder surface is smooth in the conventional case, it is difficult to generate sufficient physical or chemical bonding force with the surrounding material when inserted into the un-solidified insulation formwork, which is easy to cause the internal threaded cylinder to separate from the material under the subsequent pressure or load. SUMMARY

[0004] In view of the deficiencies of the prior art, the purpose of the present application is to provide a composite insulation formwork for building external wall, to solve the problem of insufficient bonding force between the internal threaded cylinder added in the insulation formwork for connecting the fixed steel nails and the material of the insulation formwork.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a composite insulation formwork for building external wall, comprising a base wall, the base wall is provided with an insulation formwork module on one side, a reserved positioning assembly is installed on the insulation formwork module, and a fixed steel nail extending into the interior of the base wall is connected to the interior thread of the reserved positioning assembly.

[0006] The reserved positioning assembly comprises a positioning cylinder inserted into the insulation formwork module during production, the tail end of the positioning cylinder is connected with a plugging structure for closing the tail end opening when it is inserted straight into the un-solidified insulation formwork, and the positioning cylinder is provided with a deformation structure with external protrusions when a straight pulling force is applied.

[0007] As a preferred, the insulation formwork module comprises a thermal core material arranged in the middle, cement mortar layers are arranged on both sides of the thermal core material, a bonding reinforcement layer is arranged on the side of the cement mortar layer away from the thermal core material, and a glass fiber mesh is sandwiched between the bonding reinforcement layer and the cement mortar layer.

[0008] As preferred, the glass fiber mesh cloth is a double-layer arrangement, and it is 160 g / m 2 of alkali-resistant type;

[0009] The length of the positioning cylinder is consistent with the thickness of the thermal insulation and non-dismantling module, and 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-dismantling module.

[0010] As preferred, the positioning cylinder is composed of an internally threaded cylinder penetrating through the thermal insulation core material and a receiving cylinder connected to the front end of the internally threaded cylinder, wherein the cross section of the receiving cylinder groove is T-shaped.

[0011] As preferred, at least two grooves are opened on the outer surface of the internally threaded cylinder;

[0012] The deformation structure includes a straight strip plate rotatably installed in the groove, a support plate rotatably installed on the straight strip plate, and a pull rod rotatably installed on the support plate and penetrating through the internally threaded cylinder from back to front along the groove and extending to the inside of the receiving cylinder, and widened strips are installed on both sides of the straight strip plate.

[0013] As preferred, a notch is opened on the straight strip plate to coincide with the support plate when the straight strip plate and the support plate are arranged in a horizontal state.

[0014] As preferred, when the straight strip plate and the support plate are arranged in a horizontal state, the sum of the thicknesses of the straight strip plate and the support plate coincides with the depth of the side of the groove, and the bottom of the widened strip coincides with the bottom wall of the groove when the straight strip plate is arranged in a horizontal state.

[0015] As preferred, the plugging structure is composed of a threaded ring detachably connected inside the internally threaded cylinder and a sharp cone head integrally connected to the tail end of the threaded ring, and a cross-shaped insertion slot is opened on the front side of the sharp cone head.

[0016] Through the above technical solution, the present application provides a composite thermal insulation and non-dismantling formwork for building external walls, which has at least the following beneficial effects:

[0017] 1. The composite thermal insulation and non-dismantling formwork for building external walls meets the thermal insulation requirements of building external walls and effectively realizes the integration of building thermal insulation and structure without the need for additional disassembly.

[0018] 2. After the composite thermal insulation and non-dismantling formwork for building external walls is combined and inserted into the reserved positioning assembly during the customization of the thermal insulation and non-dismantling module, the straight strip plate and the support plate arranged in an overlapping and horizontal state can be adjusted to an inclined state, forming a triangular protrusion between the straight strip plate, the support plate, and the bottom wall of the groove in the internally threaded cylinder, and the widened strips increase the width of the side edges of the straight strip plate, which are embedded in the thermal insulation and non-dismantling module together, forming mechanical interlocking, effectively preventing the internally threaded cylinder from rotating or loosening under stress.

[0028] Embodiment One

[0029] As shown in the figure, 1- Figure 5 The building outer wall composite insulation formwork can meet the building outer wall insulation requirements, realize the integration of building insulation and structure, and does not need to be disassembled. The building outer wall composite insulation formwork has a base wall 1 and an insulation formwork 2 arranged on one side of the base wall 1. The insulation formwork 2 and the base wall 1 are firmly combined through a reserved positioning assembly 3 and a fixed steel nail 4 arranged on the insulation formwork 2. The insulation formwork 2 and the base wall 1 are combined into one. A face mortar layer is directly applied on the outer surface of the insulation formwork 2, and a facing layer is directly attached. The building outer wall composite insulation formwork does not need to be disassembled, reduces the processes of formwork disassembly, cleaning and repair, significantly shortens the construction period, and improves the overall stability and seismic performance of the wall.

[0030] In order to speed up the construction progress, the insulation formwork 2 is usually customized according to the building and construction requirements in advance. In order to facilitate the subsequent combination with the fixed steel nail 4, the reserved positioning assembly 3 is generally inserted into the interior during the manufacturing process. Since the surface of the reserved positioning assembly 3 is usually smooth, the friction between the reserved positioning assembly 3 and the insulation formwork 2 is small after contact, so that the combination of the two lacks stability and does not have enough friction support, which may cause the reserved positioning assembly 3 and the insulation formwork 2 to separate. In order to effectively solve this problem, the reserved positioning assembly 3 is provided with a plurality of protrusions 31 arranged on the surface. Figures 1-4As shown, the reserved positioning assembly 3 in this embodiment includes a positioning cylinder 301 inserted into the thermal insulation and demoulding-free module 2 when it is made, and the tail end of the positioning cylinder 301 is connected with a plugging structure 302 for closing the tail end opening when it is straightly inserted into the thermal insulation and demoulding-free module 2 in which the material has not been solidified, so as to prevent the material in the thermal insulation and demoulding-free module 2 which has not been solidified from entering the positioning cylinder 301 during the process of inserting the reserved positioning assembly 3 into the thermal insulation and demoulding-free module 2, and causing damage to the thread pattern inside the positioning cylinder 301. The positioning cylinder 301 is composed of an inner threaded cylinder 3011 penetrating through the thermal insulation core material 201 and a receiving cylinder 3012 connected to the front end of the inner threaded cylinder 3011, wherein the slot type cross section of the receiving cylinder 3012 is T-shaped, mainly used for adapting the shape of the fixed steel nail 4, and at least two grooves are opened on the outer surface of the inner threaded cylinder 3011. The positioning cylinder 301 is installed with a deformation structure 303 of external protrusion increasing when a straight pulling force is applied, which includes a straight strip block 3031 rotatably installed in the groove, a support plate 3032 rotatably installed on the straight strip block 3031, a pull rod 3033 rotatably installed on the support plate 3032 and penetrating through the inner threaded cylinder 3011 from back to front along the groove and extending into the inside of the receiving cylinder 3012, and widened strips 3034 installed on both sides of the straight strip block 3031. During the stage of customizing the thermal insulation and demoulding-free module 2, the reserved positioning assembly 3 is inserted into the designated position, so that the front end plane of the receiving cylinder 3012 is on the same plane as the front side plane of the thermal insulation and demoulding-free module 2. After that, by applying a pulling force from back to front to the pull rod 3033, the straight strip block 3031 and the support plate 3032 arranged in a horizontal state are gradually adjusted to be inclined, and a triangle is formed between them and the groove bottom wall of the inner threaded cylinder 3011, for increasing the protrusion on the smooth surface of the inner threaded cylinder 3011, further improving the engagement force between the inner threaded cylinder 3011 and the thermal insulation and demoulding-free module 2, and the protrusion can be embedded in the gradually solidified thermal insulation and demoulding-free module 2 to form mechanical interlocking, preventing the inner threaded cylinder 3011 from loosening and separating from the thermal insulation and demoulding-free module 2 under the pulling force. In addition, the widened strips 3034 increase the side width of the straight strip block 3031, which also increases the engagement force with the thermal insulation and demoulding-free module 2, preventing the inner threaded cylinder 3011 from rotating or loosening under stress.

[0031] In addition, when the straight strip block 3031 is arranged horizontally, the support plate 3032 coincides with the slot opening on the straight strip block 3031, which can save space; and when the straight strip block 3031 and the support plate 3032 are arranged in a horizontal state, the sum of the thicknesses of the straight strip block 3031, the support plate 3032 and the pull rod 3033 fits the depth of the groove side, and the bottom of the widened strip 3034 fits the groove bottom wall, which ensures that the straight strip block 3031 arranged horizontally does not form a protrusion on the outside of the inner threaded cylinder 3011, facilitating direct insertion into the un-solidified thermal insulation and demoulding-free module 2.

[0032] More specifically, the thermal insulation removable formwork module 2 comprises a thermal insulation core material 201 arranged in the middle, which is 30mm polystyrene particle thermal insulation mortar, with a combustion performance of A level, both sides of the thermal insulation core material 201 are provided with a cement mortar layer 202, which can increase the overall strength and stability of the module, the side of the cement mortar layer 202 away from the thermal insulation core material 201 is provided with a bonding reinforcement layer 203, a glass fiber mesh cloth 204 is clamped between the bonding reinforcement layer 203 and the cement mortar layer 202, the glass fiber mesh cloth 204 is arranged in double layers, and it is an alkali-resistant type with a weight of 160g / m 2 The bonding reinforcement layer 203 improves the adhesion between the thermal insulation mortar, the cement mortar layer 202 and the glass fiber mesh cloth 204, enhances the integrity and reliability of the entire thermal insulation system, prevents shedding or delamination, effectively enhances the crack resistance of the thermal insulation layer with the glass fiber mesh cloth 204, avoids cracks caused by factors such as temperature changes, humidity fluctuations or building settlement, the glass fiber mesh cloth 204 can uniformly disperse stress, prevent crack propagation and ensure long-term stability of the thermal insulation layer. In addition, the polystyrene particle thermal insulation mortar and the cement mortar layer 202 have certain waterproof performance, which can effectively prevent moisture from penetrating into the thermal insulation layer and avoid the decline of thermal insulation performance caused by moisture accumulation; and the combination of the cement mortar layer 202 and the glass fiber mesh cloth 204 makes the thermal insulation system have strong freeze-thaw resistance.

[0033] Example two

[0034] In the conventional case, when the inner threaded cylinder 3011 is inserted during the stage of customizing the thermal insulation removable formwork module 2, the material in the thermal insulation removable formwork module 2 that has not completely solidified will enter the inside of the inner threaded cylinder 3011, thereby causing damage to the internal threads therein and affecting the subsequent combination effect with the fixing nails 4. In order to effectively solve this problem, as shown in Figure 2 , Figure 3 and Figure 5As shown, by making the length of the positioning cylinder 301 consistent with the thickness of the thermal insulation and disassembly-free formwork module 2, and when the two are combined, the tail end of the positioning cylinder 301 is in the same plane as the rear side of the thermal insulation and disassembly-free formwork module 2, the plugging structure 302 is composed of a threaded ring 3021 detachably connected inside the inner threaded cylinder 3011 and a sharp cone head 3022 integrally connected with the tail end of the threaded ring 3021, and a cross-shaped slot 3023 is formed in the front side of the sharp cone head 3022. Before the positioning cylinder 301 is combined with the thermal insulation and disassembly-free formwork module 2, the plugging structure 302 is detachably connected to the end of the inner threaded cylinder 3011, which blocks the opening of the end, and in addition, cooperates with the sharp cone head 3022 to facilitate the insertion of the positioning cylinder 301 into the not yet solidified thermal insulation and disassembly-free formwork module 2, while avoiding the attachment of not yet solidified material to the internal threads of the inner threaded cylinder 3011. After the positioning cylinder 301 is combined with the thermal insulation and disassembly-free formwork module 2, the threaded ring 3021 is detached from the inner threaded cylinder 3011 by inserting a tool into the cross-shaped slot 3023 and rotating the sharp cone head 3022 towards the set direction, so that the plugging structure 302 can be removed to facilitate the subsequent assembly of the fixed steel nails 4.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
