Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a thermal insulation masonry wall and a construction method thereof. Background Art

[0002] Masonry walls are a crucial component of the building envelope, and their thermal performance directly impacts a building's energy consumption. In response to national energy conservation and emission reduction policies, the construction industry has widely adopted the practice of adding insulation panels to the exterior of masonry walls to improve their thermal insulation. Traditional insulation panel installation typically utilizes a "bonding first, then anchoring" construction method, whereby the panels are first affixed to the wall surface using adhesive. After the adhesive cures, mechanical anchors are drilled and installed for reinforcement. This process has numerous technical drawbacks in practical application. First, drilling can cause irreversible damage to the masonry material. The vibration and impact generated during drilling can lead to microcracks around the hole walls. This damage is particularly noticeable in lightweight masonry with low strength or walls with poor mortar quality. Second, the anchor holes create stress concentration points. Under horizontal loads such as earthquakes, stress concentration can easily occur in the areas surrounding the holes, causing cracking in the masonry or mortar, seriously affecting the seismic performance of the wall. Third, drilling construction requires high technical skills, and improper drilling can further damage the wall. Furthermore, this traditional construction method generates large amounts of construction dust and debris, which does not meet the requirements of green construction. This construction method, which requires drilling holes in masonry, is particularly disadvantageous in areas with high seismic fortification requirements.

[0003] Therefore, there is an urgent need to develop an insulating masonry wall and a construction method thereof that can ensure that the insulation board can be installed firmly and can maximize the protection of the structural integrity of the masonry wall. Summary of the Invention

[0007] Furthermore, a leveling layer is provided on one side of the masonry wall close to the insulation board, and the insulation board is bonded to the leveling layer by an adhesive.

[0008] Furthermore, the thickness of the first clamping plate is equal to the thickness of the leveling layer.

[0023] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0024] See also Figure 1-4 This embodiment discloses an insulated masonry wall, comprising a masonry wall 1, an insulation board 2, and a plurality of connection assemblies 3 arranged along the height direction of the masonry wall 1. The connection assemblies 3 include tie bars 301 disposed between two adjacent layers of masonry blocks, fasteners 303, and connecting rods 302 arranged along the thickness direction of the masonry wall 1 and fixed to the tie bars 301. The connecting rods 302 are arranged in a plurality of intervals along the length direction of the masonry wall 1. The tie bars 301 penetrate the masonry wall 1 along the length direction of the masonry wall 1. The connecting rods 302, at one end of the connecting rods 302 adjacent to the insulation board 2, extend along the thickness direction of the masonry wall 1 to the insulation board. The insulation board is fixedly connected to the connecting rods via fasteners.

[0025] It is understood that tie bars 301 are embedded in the mortar joints of the masonry blocks during the masonry construction process to enhance the stability of the connection between the masonry wall 1 and the primary structure or structural columns, and to improve the shear resistance of the masonry wall 1. During construction, tie bars 301 are arranged in multiple groups along the height of the wall, typically with one group of tie bars 301 for every two blocks. Depending on the width of the blocks, one or more tie bars 301 can be provided; in this embodiment, two tie bars 301 are provided. Tie bars 301 extend through the length of the masonry wall 1, effectively ensuring the stability of the connection between the masonry wall 1 and the primary structure or structural columns. It is understood that the end of the tie bar 301 closest to the primary structure can be fixedly connected to a pre-embedded component embedded in the primary structure, while the end closest to the structural column can extend into the structural column, becoming integrally connected to the column during the casting process. Tie bars 301 are typically made of steel bars, preferably with a diameter ranging from 6 to 12 mm and a length tailored to the length of the masonry wall 1. The length of the connecting rod 302 is determined by the thickness of the masonry wall 1 and the thickness of the insulation board 2. The connecting rod 302 and the tie bar 301 can be fixed by welding or snap connection. The fastener 303 can be a self-tapping screw, a nut, a chemical anchor bolt, etc.

[0026] In the above-mentioned thermal insulation masonry wall, it can ensure that the thermal insulation board 2 can be installed firmly and the structural integrity of the masonry wall 1 can be protected to the maximum extent. By setting the connecting rod 302 on the tie bar 301 of the masonry wall 1, the thermal insulation board 2 can be installed non-destructively, avoiding the damage to the wall caused by the traditional drilling process, and improving the integrity and seismic performance of the wall. At the same time, the construction process is simplified and meets the requirements of green construction. The tie bar 301 passes through the wall and is fixed vertically to the connecting rod 302, forming a stable spatial force system. More specifically, the drilling operation is completely avoided, eliminating the problems of micro cracks and stress concentration in the blocks caused by drilling; secondly, the connection component 3 is constructed simultaneously with the masonry wall 1, which has better integrity and is conducive to improving seismic performance; thirdly, the connecting rod 302 can be pre-processed and formed, and only simple assembly is required on site, which makes the construction efficiency higher. This technical solution is particularly suitable for the construction of exterior wall insulation systems of buildings with high seismic performance requirements.

[0027] In this embodiment, a first clamping plate 302a is fixedly provided at one end of the connecting rod 302 close to the insulation board 2, and the first clamping plate 302a is respectively fitted with the wall surfaces on the corresponding sides of the upper and lower adjacent layers of blocks; a second clamping plate 302b is fixedly provided at one end of the connecting rod 302 away from the insulation board 2, and the second clamping plate 302b is respectively fitted with the wall surfaces on the corresponding sides of the upper and lower adjacent layers of blocks. Specifically, the first clamping plate 302a and the second clamping plate 302b are metal plates, which are respectively welded and fixed to the connecting rod 302. This technical solution achieves a two-way limit fixation of the masonry wall 1 by arranging clamping plates at both ends of the connecting rod 302. Specifically, the first clamping plate 302a and the second clamping plate 302b are respectively tightly attached to the side surfaces of the upper and lower layers of blocks to form a clamping structure, which can effectively prevent the connecting rod 302 from being displaced in the thickness direction of the masonry wall 1. More importantly, this bidirectional fixing method significantly improves the overall stability of the connection assembly 3, the axial tensioning performance between the connecting rod 302 and the masonry wall 1 is good, and the stress concentration problem caused by single-point force of traditional anchors is avoided.

[0028] In this embodiment, a leveling layer 4 is provided on the side of the masonry wall 1 close to the insulation board 2, and the insulation board 2 is bonded to the leveling layer 4 by an adhesive. Specifically, the leveling layer 4 can be made of cement mortar or polymer mortar, and the thickness is controlled within the range of 5-15 mm. During construction, a scraper can be used to evenly apply the mortar on the surface of the masonry wall 1 to form a smooth base layer. The adhesive can be a polymer-modified cement-based adhesive or a polyurethane adhesive, and the recommended application thickness is 3-8 mm. The insulation board 2 and the leveling layer 4 are bonded by a full bonding method or a spot frame method. This technical solution effectively solves the problem of hollowing and falling off of the insulation board 2 caused by the uneven surface of the masonry wall 1 in traditional construction by providing a leveling layer 4 between the masonry wall 1 and the insulation board 2. The provision of the leveling layer 4 enables the insulation board 2 to obtain a uniform support surface, thereby improving the reliability of the bonding. By rationally selecting the adhesive and controlling the construction process, the stability of the insulation board 2 during long-term use can be ensured.

[0029] In this embodiment, the thickness of the first card plate 302a is equal to the thickness of the leveling layer 4. Specifically, the first card plate 302a here is a metal plate provided at one end of the connecting rod 302 close to the insulation board 2, and its thickness must be consistent with the thickness of the leveling layer 4 after construction is completed. This technical solution enables the outer surface of the card plate to remain flush with the completed surface of the leveling layer 4 by precisely matching the thickness of the first card plate 302a with the thickness of the leveling layer 4. During specific implementation, the construction personnel can first install the connecting component 3 in place, use the first card plate 302a as a leveling reference, and control the plaster thickness of the leveling layer 4 through the outer surface of the card plate. This ensures that the leveling layer 4 can form a flat installation base surface with the first card plate 302a after construction, providing good flatness guarantee for the subsequent pasting of the insulation board 2. Compared with the traditional construction method that requires a separate leveling reference to be set, this solution integrates the leveling control and structural connection functions into the same component, which not only simplifies the construction process but also improves the leveling accuracy.

[0030] In this embodiment, the first clip 302a is a rectangular plate, and the length direction of the rectangular plate is arranged along the length direction of the masonry wall 1. Specifically, the first clip 302a adopts a rectangular plate structure, and its length direction is consistent with the length direction of the masonry wall 1. The length of the rectangular plate can be adjusted according to actual construction requirements, for example, it can be set to different specifications such as 30mm, 40mm or 50mm. The four corners of the rectangular plate can be chamfered to avoid stress concentration. Therefore, by designing the first clip 302a as a rectangular plate arranged along the length direction of the masonry wall 1, the following technical effects can be achieved: first, the rectangular plate structure is convenient for standardized production and on-site installation, which is conducive to improving construction efficiency; second, the arrangement method with the length direction consistent with the masonry wall 1 can better adapt to the structural characteristics of the masonry wall 1 and ensure the fit between the first clip 302a and the block wall surface; third, the planar structure of the rectangular plate is conducive to uniform load transfer and avoids local stress concentration. At the same time, the rectangular plate is conducive to the leveling construction of the leveling layer 4.

[0031] In this embodiment, a threaded hole 302b1 is provided at the geometric center of the first clamping plate 302a. The threaded hole 302b1 extends into the connecting rod 302 along the hole depth direction. The fastener 303 is a bolt, which is threadedly connected to the threaded hole 302b1. As a preferred embodiment, the threaded hole 302b1 and the connecting rod 302 are coaxially processed to ensure the verticality of the bolt during installation. This technical solution achieves the fixation of the insulation board 2 and the connecting rod 302 through a threaded connection, which has significant advantages over the traditional drilling anchoring method. The combination of the bolt and the threaded hole 302b1 can provide stable axial tension, ensuring a tight fit between the insulation board 2 and the leveling layer 4. Since the connecting force is transmitted to the tie bar 301 through the connecting rod 302, the main body of the masonry wall 1 does not bear the local stress caused by drilling, which is particularly suitable for construction scenarios with high seismic requirements. During the threaded connection construction, only the bolts need to be tightened. The operation process does not cause impact vibration to the wall, which is conducive to maintaining the integrity of the masonry structure.

[0032] In this embodiment, a connecting hole 302c is provided on the connecting rod 302, and the tie bar 301 is passed through the connecting hole 302c and fixed to the connecting rod 302 by welding. The connecting hole 302c is a through hole that passes through the connecting rod 302, and its hole diameter is slightly larger than the diameter of the tie bar 301 to facilitate insertion. This technical solution achieves accurate positioning of the tie bar 301 and the connecting rod 302 through the connecting hole 302c, and then forms a reliable connection through welding. The connection between the connecting rod 302 and the tie bar 301 is reliable. Specifically, the welding connection enables the tie bar 301 and the connecting rod 302 to form an integral force system, which can effectively transfer horizontal loads and reduce stress concentration at the connection site.

[0033] In this embodiment, there are two tie bars 301, and the two tie bars 301 are arranged in parallel. Specifically, the tie bars 301 are arranged in parallel, which can effectively improve the overall stability of the connection assembly 3. The two tie bars 301 extend in parallel in the length direction of the masonry wall 1 and penetrate the masonry wall 1 itself. It can be understood that the connecting rod 302 is fixedly connected to the two tie bars 301 respectively. This technical solution significantly improves the tensile performance and overall stiffness of the connection assembly 3 by providing two tie bars 301. Compared with a single tie bar 301, the double tie bar 301 arrangement can better disperse the load and avoid stress concentration. This construction method is particularly suitable for occasions that need to withstand large tensile forces, and can effectively ensure the stability of the connection between the insulation board 2 and the masonry wall 1.

[0034] In this embodiment, a connecting plate 5 is provided at one end of the tie bar 301, which is welded to each of the two tie bars 301. Specifically, the connecting plate 5 is a metal sheet, with its length perpendicular to the extension direction of the tie bar 301. This technical solution, through the provision of the connecting plate 5, achieves a rigid connection between the ends of two parallel tie bars 301. The provision of the connecting plate 5 facilitates quick and reliable connection with embedded components in the building's primary structure, improving construction convenience.

[0035] This embodiment also provides a method for constructing an insulated masonry wall, utilizing the connection assembly described above to connect the insulation board to the masonry wall, and includes the following steps: S1: pre-embedded parts (which may be embedded plates or embedded bolts, etc.) for connecting tie bars during the construction of the primary structure; S2: constructing the masonry wall, wherein the tie bars are sequentially connected to the corresponding embedded parts from bottom to top as the masonry wall is constructed; S3: completing the fixed installation of the insulation board. More specifically, the first clip 302a on the connecting rod 302 can be utilized to complete the construction of the leveling layer 4, and finally, the fixed installation of the insulation board 2 is completed. In this construction method, the connection between the tie bars 301 and the embedded parts is completed simultaneously during the construction process, ensuring the integrity and reliability of the connection assembly 3. Using the first clip 302a as a leveling reference simplifies the construction process of the leveling layer 4 and improves construction efficiency. The insulation board 2 is fixed using a combination of bonding and mechanical fixing to ensure the firmness and durability of the connection. Therefore, this construction method is particularly suitable for areas with high requirements for earthquake resistance, and can effectively reduce the damage to the masonry wall 1 structure during the construction process and improve the overall earthquake resistance of the building.
