Description

Technical Field

[0001] The utility model relates to the technical field of building thermal insulation, in particular to an external wall thermal insulation template. Background Art

[0002] The implementation of building energy-saving standards and building fire protection specifications has promoted the rapid development of wall insulation materials. In order to make full use of the insulation effect of organic insulation materials and meet the GB50016-2014 fire protection specification, the current cast-in-place insulation outer formwork widely adopts a 5cm non-combustible fire protection layer on the outside of the B-class fireproof insulation material. At present, almost all of them use 2-3cm polystyrene particle mortar or glass microbead mortar as a transition layer, plus a 3-2cm mortar protection layer to meet the 5cm non-combustible fire protection layer requirements. The main role of the transition layer is to increase the mechanical strength of the outer formwork and reduce the degree of cracking of the plastering leveling layer.

[0003] However, when polystyrene particle mortar or glass micro-bead mortar is used as a transition layer, the resulting structure has strong air permeability and water permeability, poor thermal insulation effect, and a thermal conductivity coefficient generally between 0.07-0.10W / (m·K), which greatly increases the overall thickness and unit area weight of the outer formwork; if used as an insulation layer, the overall thickness of the outer formwork will be greatly increased, and the cement mortar component contained in the polystyrene particle mortar will also greatly increase the unit area weight of the outer formwork, so it is not suitable to be used alone as an insulation layer. With the continuous improvement of insulation and energy-saving standards, the overall thickness of the outer formwork will become thicker and heavier, resulting in increasingly restricted construction and serious safety hazards.

[0004] The Chinese patent application number 201520727791.8 provides a fireproof cast-in-place concrete composite insulation formwork, which is composed of two outer protective layers and a middle inorganic material-wrapped polystyrene particle / organic insulation material composite board, and has the effects of good thermal insulation performance and high strength. However, since the inorganic material-wrapped organic particle layer is mainly inorganic material (accounting for about 90%), the inorganic material-wrapped organic particle layer and the organic insulation material layer are two material layers with very different properties, resulting in different shrinkage. When combined together, the organic insulation material layer has a greater shrinkage, which will bend the entire composite formwork, causing bending deformation, hollowing between the wall, and falling off, posing a high safety hazard. In response to this, the thickness of the inorganic material-wrapped organic particle layer and the protective layer is often thickened, which will also cause the same problem as the above-mentioned "the overall thickness of the outer formwork will become thicker and heavier, resulting in more and more restricted construction and serious safety hazards." Utility Model Content

[0005] In order to overcome the deficiencies in the above-mentioned prior art, the utility model provides an exterior wall insulation formwork, which can make the overall exterior formwork lighter, thinner, and more stable in size, is easy to construct, improves construction efficiency, greatly saves costs, is not easy to bend and deform, greatly eliminates the hidden dangers of hollowing and falling off, and is safer.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: an external wall insulation template, including an inorganic wrapped organic particle layer and an organic insulation layer, the organic insulation layer is located on one side of the inorganic wrapped organic particle layer, a mesh cloth is arranged between the inorganic wrapped organic particle layer and the organic insulation layer, and the inorganic wrapped organic particle layer, the mesh cloth, and the organic insulation layer are integrated. By compounding the mesh cloth between the inorganic wrapped organic particle layer and the organic insulation layer, a reinforcement layer is formed between the inorganic wrapped organic particle layer and the organic insulation layer, the mechanical properties between the composite surfaces of the two are improved, the phenomenon that the organic insulation layer shrinks and bends the inorganic material wrapped organic particle layer on the other side, and the inorganic wrapped organic particle layer and the organic insulation layer are more firmly bonded, avoiding the hidden danger of hollowing, peeling and falling caused by the asynchronous shrinkage of the inorganic wrapped organic particle layer and the organic insulation layer, and increasing the overall mechanical strength, thereby ensuring the stability of the performance of the entire template board. At the same time, during the production process, it can be ensured that the inorganic wrapped organic particle layer and the organic insulation layer are perfectly compounded together, and the layers are aligned. In general, the thermal insulation outer formwork has good thermal insulation, small thickness, light weight, stable size, easy construction, improved construction efficiency, cost savings, achieves A-level fire protection, has no fire safety hazards, and has a higher safety factor.

[0007] More importantly, the production can be stacked, that is, first place the inorganic coated organic particle layer, apply adhesive material, lay mesh cloth, and then place the organic thermal insulation layer, and then place the inorganic coated organic particle layer on the organic thermal insulation layer, apply adhesive material, lay mesh cloth, place the organic thermal insulation layer..., repeat this process over and over again, and finally compact it, with high production efficiency; if the mesh cloth is on the outside (whether it is the outside of the inorganic coated organic particle layer or the organic thermal insulation layer), it cannot be stacked for production, and when the adhesive material is used to stick the mesh cloth, the upper layer will also be stuck, and finally they will all be stuck together. Therefore, compared with the prior art, by compounding the mesh cloth between the inorganic coated organic particle layer and the organic thermal insulation layer, it has the above functions and can carry out stacked production, greatly improving production efficiency, and overcoming the problems of having to place a single piece in the traditional production process, occupying a large space and having low production efficiency. In addition, when the insulation formwork is used on cast-in-place walls, the mesh cloth between the inorganically coated organic particle layer and the organic insulation layer will be located on the side away from the cast-in-place wall, that is, on the outside of the organic insulation layer, and the resulting stress effect is greatly increased. When pouring concrete, the good stress effect can enhance the impact resistance and prevent the organic insulation layer from being deformed and broken into pieces due to impact.

[0008] Furthermore, the organic thermal insulation layer is provided with a plurality of stress relief seams for relieving stress.

[0009] Furthermore, the stress relief seams are arranged on both sides of the organic insulation layer, which effectively eliminates stress accumulation, so that the force of deformation of the organic insulation layer becomes very small, plays the function of offsetting stress on both sides, and further prevents the organic insulation layer from shrinking and bending.

[0010] Furthermore, the stress relief slits are arranged at intervals in the longitudinal direction of the organic thermal insulation layer, the stress relief slits on both sides are arranged alternately, the stress relief slits are parallel to each other, and the width of the stress relief slits is 0.1-1 mm, preferably 0.3-0.8 mm.

[0011] A further improvement scheme is that a groove is provided on the organic thermal insulation layer, and the groove is located on a side away from the inorganically coated organic particle layer. When pouring the wall, the slurry can enter the groove, thereby increasing the bite force between the thermal insulation formwork and the wall, and enhancing the connection performance between the thermal insulation formwork and the wall. The groove is a unidirectional groove, which can be arranged horizontally or vertically. Preferably, there are a plurality of grooves in this scheme, and the grooves are arranged at intervals in the longitudinal direction of the organic thermal insulation layer. The groove is spaced apart from the stress relief slit, and the opening depth of the stress relief slit is greater than the opening depth of the groove, and the stress relief slit is narrower than the groove.

[0012] Alternatively, instead of providing grooves, another embodiment is provided, that is, an interface layer is provided on the organic thermal insulation layer, and the interface layer is located on a side away from the inorganic coating organic particle layer. Replacing the grooves, it is easy to be integrated with the concrete structure and firmly combined with the wall.

[0013] Furthermore, a reinforcement layer is provided on the outer side of the inorganically coated organic particle layer, and the reinforcement layer is a mortar composite mesh cloth layer.

[0014] Furthermore, the thickness of the inorganic-coated organic particle layer is 1-5 cm, preferably 3-5 cm, which meets the standard requirements while greatly reducing the thickness, weight and cost.

[0015] In addition, the production method of the exterior wall insulation template mainly includes the following steps: applying a layer of adhesive material on the board surface of the inorganic coated organic particle layer, then laying a mesh cloth, and then compounding the organic insulation layer on the surface to make the two bonded together; or, applying a layer of adhesive material on the board surface of the organic insulation layer, then laying a mesh cloth, and then compounding the inorganic coated organic particle layer on the surface to make the two bonded together; in this scheme, the adhesive material is preferably bonding mortar.

[0016] The inorganic-coated organic particle layer undergoes a molding process.

[0017] Among them, before the above steps, the entire large inorganic-encapsulated organic particle layer is first produced by compression molding, and then cut into small pieces of inorganic-encapsulated organic particle layer, and the small pieces of inorganic-encapsulated organic particle layer are compounded with mesh cloth and organic thermal insulation layer. In this scheme, compression molding is as follows: when making the inorganic-encapsulated organic particle layer, the small organic particles are first heated and expanded into large particles, and then inorganic materials are added and mixed evenly to form a slurry, which is then poured into a mold, and a pressure mechanism is used to squeeze it from the outside to the inside on both sides or one side, and its volume is compressed by pressure, so that its structure is more compact, the density is greatly improved, the air permeability and water permeability are reduced, and the thermal insulation effect and waterproof effect are greatly improved.

[0018] Furthermore, a layer of interface agent is sprayed or rolled on the inner side of the organic thermal insulation layer to replace the groove, so that it is easy to be integrated with the concrete structure.

[0019] It can be seen from the above technical solutions that the utility model has the following advantages:

[0020] This solution provides an external wall insulation template. Compared with the prior art, by compounding a mesh cloth between the inorganic wrapped organic particle layer and the organic insulation layer, a reinforcement layer is formed between the inorganic wrapped organic particle layer and the organic insulation layer, thereby improving the mechanical properties between the composite surfaces of the two, reducing the phenomenon that the organic insulation layer shrinks and bends the inorganic material wrapped organic particle layer on the other side, and making the inorganic wrapped organic particle layer and the organic insulation layer more firmly bonded, avoiding the hidden danger of hollowing and peeling off and falling caused by the asynchronous shrinkage of the inorganic wrapped organic particle layer and the organic insulation layer, and increasing the overall mechanical strength, thereby ensuring the stability of the performance of the entire template body. At the same time, the production process can ensure that the inorganic wrapped organic particle layer and the organic insulation layer are perfectly compounded together, and the layers are aligned. Overall, the insulation external template has good insulation, small thickness, light weight, stable size, easy construction, improved construction efficiency, cost savings, and achieves Class A fire protection without fire safety hazards, with a higher safety factor; because the external template is thin, the wall can be made thinner, the indoor area can be increased, and the room rate is higher.

[0021] More importantly, the production can be stacked, that is, first place the inorganic coated organic particle layer, apply adhesive material, lay mesh cloth, and then place the organic thermal insulation layer, and then place the inorganic coated organic particle layer on the organic thermal insulation layer, apply adhesive material, lay mesh cloth, place the organic thermal insulation layer..., repeat this process over and over again, and finally compact it, with high production efficiency; if the mesh cloth is on the outside (whether it is the outside of the inorganic coated organic particle layer or the organic thermal insulation layer), it cannot be stacked for production, and when the adhesive material is used to stick the mesh cloth, the upper layer will also be stuck, and finally they will all be stuck together. Therefore, compared with the prior art, by compounding the mesh cloth between the inorganic coated organic particle layer and the organic thermal insulation layer, it has the above functions and can carry out stacked production, greatly improving production efficiency, and overcoming the problems of having to place a single piece in the traditional production process, occupying a large space and having low production efficiency. In addition, when the insulation formwork is used on cast-in-place walls, the mesh cloth between the inorganically coated organic particle layer and the organic insulation layer will be located on the side away from the cast-in-place wall, that is, on the outside of the organic insulation layer, and the resulting stress effect is greatly increased. When pouring concrete, the good stress effect can enhance the impact resistance and prevent the organic insulation layer from being deformed and broken into pieces due to impact.

[0022] What is more important is that the structure of the exterior wall insulation formwork determines that its production method can pre-produce large blocks of inorganic-coated organic particle layer blocks and organic insulation layer blocks, fully age them to stabilize the size, eliminate deformation stress, and then cut them into designed thickness sizes; when compounding, first apply adhesive material to the inorganic-coated organic particle layer, lay a mesh cloth, and place the organic insulation layer. Of course, whether the adhesive material is applied to the inorganic-coated organic particle layer or the organic insulation layer, they can be reversed and interchanged, and the upper and lower positions of the inorganic-coated organic particle layer and the organic insulation layer can be reversed and interchanged. After compaction; if it is a traditional thermal insulation formwork production process, whether it is a foamed organic thermal insulation layer on an inorganic coated organic particle layer, or an inorganic coated organic particle layer is scraped on an organic thermal insulation layer, one thermal insulation layer is first produced and cured and aged to stabilize, and then another thermal insulation layer is scraped or injection molded. The size of one material has been finalized in advance, and the other will shrink and deform sharply during the curing process after being attached. The shrinkage of the two materials is even more asynchronous, resulting in serious stratification stress at the interface, which is easy to bend and deform at the lightest, and peeling and delamination and hollowing at the worst, leaving a major safety hazard of falling off later. Therefore, compared with the prior art, by pre-aging the inorganic coated organic particle layer and the organic thermal insulation layer, and then compounding the two materials with a bonding material mesh cloth, the problem of asynchronous aging and shrinkage between different materials is greatly eliminated, and the problem of bending, deformation, peeling, delamination and hollowing caused by stress accumulation caused by asynchronous shrinkage is overcome, which effectively avoids the major safety hazard of falling and injuring people during long-term application after construction.

[0029] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0030] like Figures 1 to 4As shown, this specific embodiment provides an exterior wall insulation template, including an inorganic coated organic particle layer 1 and an organic insulation layer 2, the organic insulation layer 2 is located on one side of the inorganic coated organic particle layer 1, a mesh cloth 3 is arranged between the inorganic coated organic particle layer 1 and the organic insulation layer 2, the inorganic coated organic particle layer 1, the mesh cloth 3, and the organic insulation layer 2 are an integrated structure, the thickness of the inorganic coated organic particle layer 1 is preferably 3-5cm, and the thickness of the organic insulation layer 2 is designed according to actual conditions. By compounding a mesh cloth between the inorganic coated organic particle layer and the organic thermal insulation layer, a reinforcement layer is formed between the inorganic coated organic particle layer and the organic thermal insulation layer, thereby improving the mechanical properties between the composite surfaces of the two, reducing the phenomenon that the shrinkage of the organic thermal insulation layer causes the inorganic material coated organic particle layer on the other side to bend, and making the inorganic coated organic particle layer and the organic thermal insulation layer more firmly bonded, thereby avoiding the hidden danger of hollowing, peeling and falling caused by the asynchronous shrinkage of the inorganic coated organic particle layer and the organic thermal insulation layer, and increasing the overall mechanical strength, thereby ensuring the stability of the performance of the entire template board. At the same time, since the inorganic coated organic particle layer and the organic thermal insulation layer cannot be aligned when they are directly compounded into one piece (the inorganic coated organic particle layer and the organic thermal insulation layer are prone to stagger and offset), compounding a layer of mesh cloth between them through adhesive material can ensure that the inorganic coated organic particle layer and the organic thermal insulation layer are perfectly compounded together, and the layers are aligned, thereby ensuring the stability of the performance of the entire template board.

[0031] Further, in order to solve the problem of stress concentration after the insulation template is mounted on the wall, a plurality of stress relief seams 4 are provided on the organic insulation layer 2, which can be arranged horizontally or vertically. The stress relief seams 4 are arranged on both sides of the organic insulation layer 2. Preferably, the stress relief seams 4 are arranged at intervals in the longitudinal direction of the organic insulation layer 2 (see Figure 1 ), the stress relief seams 4 on both sides are arranged in a staggered manner, the stress relief seams 4 are parallel to each other, the width of the stress relief seams 4 is 0.3-0.8mm, preferably 0.5mm, stress relief seams are set on both sides of the organic insulation layer, the stress seams transmit force, the force gradually weakens, and the force that deforms the organic insulation layer becomes very small, which plays the role of offsetting the stress on both sides, and further prevents the organic insulation layer from shrinking and bending. At the same time, it reduces or eliminates the stress generated after the insulation template is put on the wall, and has a better stress relief effect.

[0032] The organic thermal insulation layer 2 is provided with a groove 5, the groove 5 is located on a side away from the inorganic coated organic particle layer 1, the groove 5 is a unidirectional groove, and the groove 5 is provided with a plurality of grooves along the longitudinal direction of the organic thermal insulation layer, which can be arranged horizontally or longitudinally. Preferably, the groove 5 in this scheme has a plurality of grooves, and the grooves 5 are arranged at intervals in the longitudinal direction of the organic thermal insulation layer 2 (see Figure 1), when pouring the wall, the slurry can enter the groove 5, increase the bite force between the insulation formwork and the wall, and enhance the connection performance between the insulation formwork and the wall. Specifically, the groove 5 is spaced apart from the stress relief seam 4, the opening depth of the stress relief seam 4 is greater than the opening depth of the groove 5, and the stress relief seam 4 is narrower than the groove 5. In other specific embodiments, the groove 5 may not be provided, and another method is adopted, that is: an interface layer is provided on the organic insulation layer 2, and the interface layer is located on the side away from the inorganic coated organic particle layer 1, replacing the groove 5, and is easy to be integrated with the concrete structure and firmly combined with the wall.

[0033] In addition, a reinforcing layer 6 is provided on the outer side of the inorganically coated organic particle layer 1 (ie, the side away from the organic thermal insulation layer), and the reinforcing layer 6 is a mortar layer or a mortar composite mesh cloth layer.

[0034] It should be noted that the inorganic material in the inorganic material-wrapped organic particle layer 1 is preferably cement, porous silicon, fly ash or slag powder, and the organic particles are preferably polystyrene foam particles; the organic insulation layer 2 is preferably polyurethane rigid foam plastic board, graphite polystyrene board, polystyrene foam plastic board, phenolic plastic foam board.

[0035] The insulation template can be stacked for production, that is, first place the inorganic coated organic particle layer 1, apply the adhesive material, lay the mesh cloth 3, and then place the organic insulation layer 2, and then place the inorganic coated organic particle layer 1 on the organic insulation layer 2, apply the adhesive material, lay the mesh cloth 3, place the organic insulation layer 2..., repeat the process over and over again, and finally compact it, so the production efficiency is high; if the mesh cloth 3 is on the outside (whether it is the outside of the inorganic coated organic particle layer 1 or the organic insulation layer 2), it cannot be stacked for production, and when the adhesive material is used to stick the mesh cloth 3, the upper layer will also be stuck, and finally they are all stuck together. Therefore, compared with the prior art, by compounding the mesh cloth 3 between the inorganic coated organic particle layer 1 and the organic insulation layer 2, it has the above functions and can be stacked for production, which greatly improves the production efficiency and overcomes the problem that the traditional production process must be placed individually, occupies a large space and has low production efficiency. In addition, when the insulation formwork is used on a cast-in-place wall, the mesh cloth 3 between the inorganically coated organic particle layer 1 and the organic insulation layer 2 will be located on the side away from the cast-in-place wall, that is, relatively speaking, on the upper and outer side of the organic insulation layer 2, and the resulting stress effect is greatly increased. When pouring concrete, the good stress effect can enhance the impact resistance and prevent the organic insulation layer 2 from being deformed and broken into pieces due to impact.

[0036] The production method of the exterior wall insulation template mainly includes the following steps: firstly, produce the entire large inorganic coated organic particle layer 1 by compression molding, then cut it into small pieces of inorganic coated organic particle layer 1, and compound the small pieces of inorganic coated organic particle layer 1 with mesh cloth 3 and organic insulation layer 2; specifically, apply a layer of adhesive material on the board surface of the inorganic coated organic particle layer 1, then lay the mesh cloth 3, and then compound the organic insulation layer 2 on the surface, so that the two are bonded together; or, apply a layer of adhesive material on the board surface of the organic insulation layer 2, then lay the mesh cloth 3, and then compound the inorganic coated organic particle layer 1 on the surface, so that the two are bonded together; in this scheme, the adhesive material is preferably bonding mortar. Firstly, produce a large piece of inorganic coated organic particle layer 1, and then cut it into small pieces for compounding, which greatly improves the production efficiency. Among them, the compression molding is: when making the inorganic-coated organic particle layer 1, the small organic particles are first heated and expanded into large particles, and then the inorganic material is added and mixed evenly to form a slurry, which is then poured into the mold and squeezed from the outside to the inside on both sides or one side by a pressure mechanism, and its volume is compressed by pressure to make its structure denser.

[0037] Among them, a plurality of unidirectional grooves 5 are provided on the side of the organic thermal insulation layer 2 away from the inorganic coated organic particle layer 1; stress relief seams 4 are provided on both sides of the organic thermal insulation layer 2; and a reinforcement layer 6 formed by a composite of mortar and mesh cloth is provided on the outside of the inorganic coated organic particle layer 1. It should be noted that the grooves and stress relief seams can be provided before the organic thermal insulation layer is composited with the inorganic coated organic particle layer, or after the organic thermal insulation layer is composited with the inorganic coated organic particle layer, and the same is true for the reinforcement layer. In addition, in other specific embodiments, a layer of interface agent can be sprayed or rolled on the inside of the organic material to replace the grooves, so as to facilitate integration with the concrete structure and firmly combine with the wall.

[0038] It should be noted that the method is to pre-produce large blocks of inorganic-coated organic particle layer blocks and organic thermal insulation layer blocks, which can be fully aged to stabilize the size and eliminate deformation stress, and then cut into designed thickness sizes; when compounding, first apply adhesive material to the inorganic-coated organic particle layer 1, spread the mesh cloth 3, and place the organic thermal insulation layer 2. Of course, whether the inorganic-coated organic particle layer 1 or the organic thermal insulation layer 2 is coated with adhesive material, the upper and lower positions of the inorganic-coated organic particle layer 1 and the organic thermal insulation layer 2 can be reversed and interchanged, and finally press In fact, if the traditional process, whether it is foaming an organic insulation layer 2 on an inorganically coated organic particle layer 1, or scraping an inorganically coated organic particle layer 1 on an organic insulation layer 2, is to first produce a good insulation layer, solidify and age to stabilize, and then scrape or injection mold another insulation layer. The size of one material has been finalized in advance, and the other will shrink and deform sharply during the curing process after being attached. The shrinkage of the two materials is even more asynchronous, resulting in serious stratification stress at the interface, which is easy to bend and deform at the lightest, and peeling and delamination and hollowing at the worst, leaving a major safety hazard of falling off later. Therefore, compared with the prior art, by pre-aging the inorganically coated organic particle layer 1 and the organic insulation layer 2, and then compounding the two materials through the bonding material mesh cloth 3, the problem of asynchronous aging and shrinkage between different materials is greatly eliminated, and the problem of bending, deformation, peeling, delamination and hollowing caused by stress accumulation caused by asynchronous shrinkage is overcome, which effectively avoids the major safety hazard of falling and injuring people during long-term use after construction.
