Description

Technical Field

[0001] This utility model relates to the field of ancient building construction technology, specifically to a composite sandwich structure for thermal insulation of ancient building walls. Background Technology

[0002] Traditional ancient buildings typically have walls constructed of solid blue bricks or hollow bricks, which are thick but have low thermal resistance, resulting in cold interiors in winter and stuffy interiors in summer. Currently, during the restoration and construction of ancient buildings, to further improve the thermal insulation of the walls, an insulation structure made of EPS / XPS boards and polymer mortar is usually added to the inner or outer walls. To ensure insulation effectiveness, the EPS / XPS boards are often quite thick, further increasing the overall wall thickness and potentially impacting the historical appearance of the building. Furthermore, the finishing layer on the outer wall is more susceptible to cracking, damage, and even detachment under prolonged rain erosion. Additionally, the EPS / XPS boards usually require anchoring expansion bolts for further stabilization, which can further damage the brickwork and brick joints. Utility Model Content

[0003] The purpose of this utility model is to provide a composite sandwich structure for thermal insulation of ancient building walls. Compared with traditional insulation structures added to the inner or outer walls of the wall, this structure is less prone to cracking, damage, or even detachment. At the same time, it does not require additional anchoring expansion bolts or adhesives, effectively avoiding unnecessary structural damage to the bricks on the main wall due to the addition of the insulation structure. It also avoids unnecessary interference or even damage to the appearance of ancient buildings caused by exposed modern materials, thus preventing visual differences. It has high environmental adaptability and durability, effectively reduces later maintenance, lowers the overall cost of use, and meets the construction needs of ancient buildings with different architectural styles.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A composite sandwich structure for thermal insulation of ancient building walls includes a main wall body, which comprises several sets of bricks with two sets of grooves staggered at the upper and lower ends to form a right-angled "S" shape, and multiple sets of insulation layers inserted into the grooves of the bricks.

[0006] Preferably, the brick has multiple sets of horizontal or vertical through grooves arranged at intervals, and multiple sets of steel bars are threaded through the vertical through grooves, and the insulation layer is threaded through the multiple sets of steel bars.

[0007] Preferably, the insulation layer includes an intermediate layer and an outer layer bonded to both sides of the intermediate layer, wherein the intermediate layer is provided with multiple sets of reinforcing bars.

[0008] Preferably, the outer wall surfaces at both ends of the brick are either flat or a combination of multiple sets of facets formed by opening multiple sets of spaced grooves.

[0009] Preferably, the wall body further includes several sets of second bricks with second grooves formed in a right-angled "C" shape on the upper and lower end faces.

[0010] Compared with the prior art, this utility model has the following advantages and effects:

[0011] This utility model relates to a composite sandwich structure for thermal insulation of ancient building walls. The main body of this wall provides a certain degree of structural stability while incorporating the shape of the bricks and a staggered arrangement of the insulation layer within the grooves between adjacent rows of bricks within the main body. Compared to existing technologies that use EPS / XPS boards and polymer mortar to add insulation to the inner or outer wall, this design uses right-angled "S"-shaped grooves to interlock the mortar and insulation layer, embedding the insulation layer within the grooves rather than attaching it to the surface. This effectively reduces the risk of interface peeling caused by temperature stress and freeze-thaw cycles in traditional external insulation layers. Furthermore, the grooves on the bricks create capillary channels, which, combined with the breathability of the mortar, effectively reduce frost heave cracking caused by moisture accumulation in traditional external insulation (compared to the sealing properties of polymer mortar). This reduces the likelihood of cracking, damage, or even detachment, and also offers high environmental adaptability, durability, and safety. This design effectively reduces subsequent maintenance, lowers overall operating costs, and eliminates the risk of fire spread associated with traditional EPS / XPS external insulation. Furthermore, the groove depth on the bricks is greater than half the corresponding thickness of the brick in the groove's direction, ensuring that multiple sets of insulation layers arranged in a staggered pattern within the wall structure provide insulation at corresponding heights. This allows the insulation layer to be embedded and anchored to the bricks, completely concealing it within the wall structure. Combined with mortar, this ensures the stability of the insulation layer's position without the need for additional anchoring bolts or adhesives, effectively preventing unnecessary damage to the bricks on the wall structure due to the addition of insulation. It is also compatible with traditional "dry-laid silk seam" or "flowing white" masonry methods, maintaining the texture of exposed brick walls and avoiding unnecessary interference or damage to the ancient architectural style caused by exposed modern materials, thus meeting the construction needs of ancient buildings with different architectural styles.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0016] See Figure 1-2 This embodiment relates to a composite sandwich structure for thermal insulation of ancient building walls, including a wall body 100. The wall body 100 includes several sets of bricks 1 with two sets of grooves 11 staggered at the upper and lower ends to form a right-angled "S" shape, and multiple sets of thermal insulation layers 2 inserted into the grooves 11 of the bricks 1.

[0017] Specifically in this embodiment, such as Figure 1 The overall structural design of this type of composite sandwich structure for thermal insulation of ancient building walls, as shown, can be adopted during the construction or reconstruction of ancient buildings. Figure 1 The main wall structure 100 is constructed using the following method, which can be combined with specific details. Figure 2 As shown, the insulation layer 2 can be made of any insulation material commonly used in the prior art, such as EPS board, XPS board, or rock wool board, and can be selectively used according to usage requirements. The upper and lower ends are staggered with two sets of grooves 11 forming a number of sets of bricks 1 in a right-angled "S" shape, which can be used for... Figure 1 or Figure 2 The method shown involves arranging and stacking mortar 101, and simultaneously, during the arrangement and stacking of several groups of bricks 1, the insulation layer 2 of appropriate thickness is inserted into the groove 11 formed by several groups of bricks 1 in the same row over a certain span. This, combined with the shape setting of the bricks 1, achieves multiple sets of insulation layers 2 as shown... Figure 1In the state shown, the bricks are arranged in a staggered manner within the main body 100 of the wall. The process of stacking several groups of bricks 1 with mortar 101 can ensure the stability of the insulation layer 2 within the groove 11. After the main body 100 of the wall at the corresponding height is completed, its top and sides can be smoothed with mortar 101 according to the construction requirements. This type of wall structure 100 provides a certain degree of support and stability. Combined with the shape of the bricks 1 and the staggered arrangement of the insulation layer 2 within the grooves 11 between several groups of bricks 1 in adjacent rows within the wall structure 100, this method offers advantages over existing technologies that use EPS / XPS boards and polymer mortar 101 to form insulation structures on the inner or outer walls. In this method, the bricks 1 are interlocked with the mortar 101 and insulation layer 2 through right-angled "S"-shaped grooves 11, creating an interlocking structure. The insulation layer 2 is embedded in the grooves 11 rather than attached to the surface, effectively reducing the risk of interface peeling caused by temperature stress and freeze-thaw cycles in traditional external insulation layers 2. Simultaneously, the grooves 11 on the bricks 1 form capillary channels, which, combined with the breathability of the mortar 101, effectively reduce the risk of frost heave cracking caused by moisture accumulation in traditional external insulation (compared to the sealing properties of polymer mortar 101). This reduces the likelihood of cracking, damage, or even detachment, and provides high environmental adaptability, durability, and safety, effectively reducing the risk of future problems. This design addresses the challenges of maintenance, reducing overall operating costs, and mitigating the risk of fire spread associated with traditional EPS / XPS external insulation. Furthermore, by ensuring that the groove depth of the groove 11 on the brick 1 is greater than half the thickness of the brick 1 in the groove's direction, it guarantees that multiple sets of insulation layers 2, arranged in a staggered pattern within the wall body 100, provide insulation at corresponding heights. This allows the insulation layer 2 to be embedded and anchored to the brick 1, completely concealing it within the wall body 100. Combined with mortar 101, this ensures the stability of the insulation layer 2 without the need for additional anchoring bolts or adhesives. This effectively prevents unnecessary damage to the bricks 1 on the wall body 100 caused by the addition of insulation structures. Simultaneously, it is compatible with traditional architectural techniques such as "dry-laid silk seams" or "flowing white" masonry, maintaining the texture of exposed brick walls and preventing modern materials from interfering with or damaging the architectural style, thus avoiding visual discrepancies and meeting the construction needs of ancient buildings with different architectural styles.

[0018] The brick 1 has multiple sets of horizontally or vertically arranged through slots 12, and multiple sets of steel bars 102 are threaded through the vertically arranged through slots 12. The insulation layer 2 is threaded through the multiple sets of steel bars 102. For details on the multiple sets of horizontally or vertically arranged through slots 12, please refer to [link to relevant documentation]. Figure 2 and Figure 3As shown, the structure can be selected according to construction needs. When multiple sets of through grooves 12 are opened horizontally or vertically on the brick 1, the weight of the brick 1 can be reduced while also dispersing the local stress of the brick 1, avoiding crack concentration, and improving seismic performance. At the same time, compared with solid bricks, the multiple sets of through grooves 12 opened on the brick 1 form an air layer, which can significantly reduce the thermal bridging effect. In addition, when multiple sets of through grooves 12 are opened vertically in the brick 1 and its groove 11, they can be combined with... Figure 3 Taking this construction method as an example, the main body 100 of this wall can be constructed with multiple sets of steel bars 102 according to the needs of ancient building construction, combined with the foundation. The bricks 1 can be laid by passing through the longitudinally opened through grooves 12 and inserting them through the multiple sets of steel bars 102 at corresponding positions, combined with mortar 101. The insulation layer 2 can be stably inserted through the steel bars 102, depending on its thickness and material, to ensure that the whole structure will not break, and then inserted and fixed in the grooves 11 of the bricks 1. In addition, the diameter of the through grooves 12 outside the grooves 11 can be larger than the diameter of the steel bars 102 to facilitate the laying of bricks. While the bricklaying is being carried out, grouting can be performed in the through grooves 12 later according to construction needs. This, combined with the structure formed by multiple sets of steel bars 102 inside the wall body 100, can further improve the structural stability and load-bearing capacity of the wall body 100. It can also further improve the positional stability of the insulation layer 2 in the grooves 11 on the brick 1. The multiple longitudinally opened through grooves 12 on the brick 1 can also further improve the positional stability of the brick 1 and the convenience of stacking operations, thereby improving the construction efficiency of the entire wall body 100 construction process and meeting different construction requirements.

[0019] The insulation layer 2 includes an intermediate layer 21 and outer layers 22 bonded to both sides of the intermediate layer 21. The intermediate layer 21 is provided with multiple sets of reinforcing bars 102, specifically from... Figure 1 or Figure 2 As can be seen, the middle layer 21 of the insulation layer 2 can be made of any insulation material commonly used in the prior art, such as EPS board, XPS board or rock wool board, while the outer layer 22 can be integrally bonded to the middle layer 21 on both sides of the middle layer 21 with adhesive. The outer layer 22 can be made of protective materials such as calcium silicate board or aluminum foil composite cloth. Therefore, when the insulation layer 2 with this structure is installed through the middle layer 21 on multiple sets of steel bars 102, it can effectively reduce the degree of deformation of the insulation layer 2 and the probability of structural damage. It is convenient to install the insulation layer 2 and can also reduce the degree of wear and even structural damage to its surface, further improving the thermal insulation effect and stability of the insulation layer 2.

[0020] The outer walls at both ends of the brick 1 are designed with a plane 13 or a combination of multiple sets of facets 14 formed by opening multiple sets of spaced grooves 140. Figure 1-3 As can be seen, the bricks 1 with this structure can make the two sides of the wall body 100 formed by this structure have either a facet 14 or a plane 13 or a combination thereof. The side of the wall body 100 with the facet 14 can be directly exposed to the external environment; while the side of the wall body 100 with the plane 13 can be easily smoothed with mortar 101 or connected with the corresponding repair structure of ancient buildings, as well as sprayed with murals or carved with patterns on the plane 13, which further improves the structural flexibility and applicability of this wall body 100.

[0021] The wall body 100 also includes several sets of second bricks 3 forming a right-angled "C" shape with second grooves 31 formed on the upper and lower end faces, as detailed in the following document. Figure 4 As shown, the wall body 100 can be connected with second bricks 3 on the upper and lower end faces according to construction needs. Combined with the structure of the second bricks 3 forming a right-angled "C" shape by opening the second groove 31, it can further improve the protective effect of the insulation layer 2 at the corresponding end faces of the upper and lower ends of the wall body 100. The brick 1 body located below the second groove 31 can be placed below the ground and integrated with the foundation or embedded with the eaves of the external ancient building. While ensuring the heat insulation effect of the insulation layer 2 inside the wall body 100, it can also further improve the structural stability, flexibility and applicability of this type of wall body 100.
