Description
Technical Field
[0001] The present application relates to the technical field of building engineering construction, and in particular to a heat insulation structure for concrete buildings. Background Art
[0002] The thermal insulation structure for concrete buildings mainly installs thermal insulation components on the outer wall of the concrete building wall. The thermal insulation components can play the role of thermal insulation, and the thermal insulation components are mainly composed of thermal insulation board materials. The common characteristics of thermal insulation materials are light weight, looseness, porous or fibrous, and the stagnant air inside them blocks the conduction of heat. Among them, inorganic materials have the characteristics of non-combustibility, wide operating temperature, and good chemical corrosion resistance. Organic materials have the characteristics of low water absorption and good impermeability. The combination of the two can achieve the ideal purpose of thermal insulation.
[0003] However, in the prior art, the thermal insulation structure is mainly constructed by fixing a single-sided inorganic foam insulation board or other material insulation board to the building wall through bonding mortar. The thermal insulation effect of the single-sided inorganic foam insulation board or other material insulation board is limited. When encountering extremely low or high temperatures, the inorganic foam insulation board or other material insulation board cannot effectively insulate and heat, resulting in a decrease or increase in the indoor temperature of the building. Moreover, when the thermal insulation structure is installed on the building wall, its connection stability is poor, which can easily cause the deformation and falling off of the decorative panel, thereby increasing the subsequent maintenance cost.

[0029] In order to facilitate understanding of the heat insulation structure for concrete buildings provided in the embodiments of the present application, its application scenario is first described.
[0030] The thermal insulation structure for concrete buildings mainly installs thermal insulation components on the outer wall of the concrete building wall. The thermal insulation components can play the role of thermal insulation, and the thermal insulation components are mainly composed of thermal insulation board materials. The common characteristics of thermal insulation materials are light weight, looseness, porous or fibrous, and the stagnant air inside them blocks the conduction of heat. Among them, inorganic materials have the characteristics of non-combustibility, wide operating temperature, and good chemical corrosion resistance. Organic materials have the characteristics of low water absorption and good impermeability. The combination of the two can achieve the ideal purpose of thermal insulation.
[0031] However, in the prior art, the thermal insulation structure is mainly constructed by fixing a single-sided inorganic foam insulation board or other material insulation board to the building wall through bonding mortar, and the single-sided inorganic foam insulation board or other material insulation board has limited thermal insulation effect. When encountering extremely low or high temperatures, the inorganic foam insulation board or other material insulation board cannot effectively insulate and heat, resulting in a decrease or increase in the indoor temperature of the building; and when the thermal insulation structure is installed on the building wall, its connection stability is poor, which can easily cause the deformation and fall off of the decorative panel, increasing the subsequent maintenance cost. In view of this, the present application provides a thermal insulation structure for concrete buildings, which has a firm and reliable connection performance and a significant thermal insulation effect at a relatively low overall weight.
[0032] refer to Figure 1The thermal insulation structure for concrete buildings provided in the embodiment of the present application includes: a thermal insulation board structure limitedly connected to a building wall 1; the building wall 1 is a brick wall or a concrete wall, and installing and fixing the thermal insulation board structure on the building wall 1 can effectively improve the thermal insulation effect, and the overall weight of the thermal insulation board structure is light, and has good connection stability, which improves the thermal insulation of the interior of the building, and makes the decorative board structure firmly and stably connected, reducing the risk of later damage.
[0033] In the present application, the insulation board structure is STP insulation board 8 and inorganic foam insulation board 3 from the inside to the outside; STP insulation board 8 adopts ultra-thin design to reduce the overall weight, and the thickness of STP insulation board 8 is one-fourth of the thickness of inorganic foam insulation board 3. For example, the thickness of STP insulation board 8 is 10mm, and the thickness of inorganic foam insulation board 3 is 40mm. The combined design with a relatively light overall weight is adopted to reduce the overall weight while ensuring strong connection stability.
[0034] Combination Figure 3 As shown in the figure, the STP thermal insulation board 8 is adhesively connected to the building wall 1, and the side of the STP thermal insulation board 8 facing the building wall 1 is provided with a convex structure that can be embedded in the building wall 1; the STP thermal insulation board 8 is provided with multiple convex structures, each of which is a convex block 10 that is an integral structure with the STP thermal insulation board 8. Through the provided convex structure, an embedded connection can be achieved with the building wall 1 to ensure a good connection relationship. It is preferred to set the convex blocks 10 at equal intervals on the back of the STP thermal insulation board 8, and after measuring and positioning the position of the convex blocks 10 on the building wall 1, a recessed hole 11 that matches the convex block 10 is drilled by an electric hammer.
[0035] Specifically, a plurality of recessed holes 11 are provided on the building wall 1, and a plurality of raised blocks 10 and a plurality of recessed holes 11 are plugged in and matched one by one. The recessed holes 11 are drilled with an electric hammer, and the drilling process is simple. The recessed holes 11 and the plurality of raised blocks 10 are plugged in and limitedly connected. Moreover, the recessed depth of each recessed hole 11 is greater than the protruding thickness of the corresponding raised block 10. It is convenient to fill the mortar, enhance the connection effect, and avoid the later displacement of the STP thermal insulation board 8. The diameter of each recessed hole 11 is greater than the diameter of the corresponding raised block 10. It is convenient to fill the mortar, enhance the connection effect, and avoid the later displacement of the STP thermal insulation board 8.
[0036] Exemplarily, the diameter of the raised block 10 is 18 mm, and the protruding thickness of the raised block 10 is 10 mm; when the recessed depth of the recessed hole 11 is greater than the protruding thickness of the raised block 10, the recessed depth of the recessed hole 11 is 15 mm, and when the diameter of the recessed hole 11 is greater than the diameter of the raised block 10, the diameter of the recessed hole 11 is 28 mm, so that there is a certain gap between the recessed hole 11 and the raised block 10, which is convenient for mortar filling to increase the contact surface and enhance the overall firmness and reliability.
[0037] Continue reading Figure 1 and Figure 2 After the recessed hole 11 is opened on the building wall 1, the first bonding mortar layer 2 is applied; the mortar of the first bonding mortar layer 2 also fills the recessed hole 11. When the STP thermal insulation board 8 is bonded to the first bonding mortar layer 2, the mortar of the first bonding mortar layer 2 fills the gap between any group of protrusions 10 and the recessed hole 11. When the STP thermal insulation board 8 is installed by pressing, multiple protrusions 10 enter the recessed hole 11 and squeeze the mortar of the first bonding mortar layer 2 to fill the existing gap, thereby achieving a larger contact surface and ensuring its connection strength.
[0038] At the same time, the inorganic foam insulation board 3 is anchored to the building wall 1; the inorganic foam insulation board 3 is closely attached to the STP insulation board 8, and the thickness of the STP insulation board 8 is less than the thickness of the inorganic foam insulation board 3. Thus, the ultra-thin performance of the STP insulation board 8 is utilized to reduce the overall weight.
[0039] Specifically, a plurality of anchor holes are reserved on the STP thermal insulation board 8; the anchor holes are preferably distributed at the four corners and do not destroy the overall thermal insulation structure of the STP thermal insulation board 8; Figure 3 As shown in the figure, the inorganic foam insulation board 3 is fixedly connected to the building wall 1 after passing through multiple anchoring holes through multiple anchoring pieces 9. The vacuum performance of the STP insulation board 8 is not damaged, and the positions of the anchoring holes are determined in an equidistant positioning manner, so as to achieve a better effect of fixing the STP insulation board 8 and the inorganic foam insulation board 3. The anchoring piece 9 adopts an expansion bolt or an expansion plug, etc., which can ensure the connection reliability with the building wall 1 while achieving a stable connection between the inorganic foam insulation board 3 and the STP insulation board 8.
[0040] In addition, the decorative panel structure in the present application includes: an anti-crack mesh cloth 5 bonded to the side of the inorganic foam insulation board 3 facing away from the STP insulation board 8, and a decorative panel 7 bonded to the outer surface of the anti-crack mesh cloth 5. Specifically, the inorganic foam insulation board 3 is connected to the anti-crack mesh cloth 5 through the second bonding mortar layer 4. By evenly applying the first bonding mortar layer 2, the connection performance between the inorganic foam insulation board 3 and the anti-crack mesh cloth 5 is improved. In addition, the anti-crack mesh cloth 5 is a mesh cloth made of alkali-resistant glass fiber material, and the anti-crack mesh cloth 5 is connected to the decorative panel 7 through the third bonding mortar layer 6. The decorative panel 7 is stably connected, and while having high thermal insulation performance, it prevents the decorative panel 7 from deforming and falling off.
[0041] It can be seen from the above structure that by arranging the installation position of the insulation board structure on the building wall 1, and opening the recessed hole 11 according to the position calculation, the first bonding mortar layer 2 is evenly applied after the recessed hole 11 is opened, and the STP insulation board 8 is positioned on the building wall 1 by pressing, and the raised block 10 extends into the recessed hole 11 and squeezes the mortar of the first bonding mortar layer 2 to fill the gap; drilling is performed according to the position of the anchor hole, and expansion bolts are pre-embedded. The screw of the expansion bolt passes through the inorganic foam insulation board 3 in the reverse direction and is locked by a nut, thereby ensuring the close fit of the inorganic foam insulation board 3 and the STP insulation board 8 and the connection stability with the building body. Then, the second bonding mortar layer 4 is evenly applied on the surface of the inorganic foam insulation board 3, and the anti-cracking mesh cloth 5 is attached on the second bonding mortar layer 4. After the anti-cracking mesh cloth 5 is firm, the third bonding mortar layer 6 is evenly applied on the outer surface of the anti-cracking mesh cloth 5, and then the decorative panel 7 is installed, and the overall connection performance is reliable.
[0042] In the present application, the vacuum performance of the ultra-thin STP insulation board 8 is utilized in combination with the inorganic foam insulation board 3 to improve the thermal insulation effect of the building. The connection between the STP insulation board 8 and the inorganic foam insulation board 3 and the building wall 1 is firm and reliable, the overall weight is light, and it has a long service life.
