Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a connection structure between an insulation board and a masonry wall. Background Technology

[0002] As an important component of building envelope, masonry walls directly affect the building's energy consumption level due to their thermal performance. In response to national energy conservation and emission reduction policies, the construction industry commonly uses insulation boards on the outer surface of masonry walls to improve their thermal insulation performance. Traditional insulation board installation typically employs a "first adhesive, then anchor" method, where the insulation board is first adhered to the wall surface using adhesive, and then mechanical anchors are installed after the adhesive has cured. This process has several technical drawbacks in practical applications: First, drilling causes irreversible damage to the masonry material. The vibration and impact generated during drilling can lead to micro-cracks around the hole walls, which is particularly noticeable in lightweight masonry blocks with low strength or walls with poor mortar quality. Second, anchor holes create stress concentration points. Under horizontal loads such as earthquakes, stress concentration can easily occur around the holes, causing cracks in the masonry blocks or mortar and severely affecting the seismic performance of the wall. Third, drilling requires high operational skills, and improper drilling operations can further exacerbate the damage to the wall. In addition, this traditional construction method generates a large amount of construction dust and debris, which does not meet the requirements of green construction. Especially in areas with high seismic fortification requirements, this construction method that requires drilling into the masonry is even more disadvantageous.

[0003] Therefore, there is an urgent need to develop a new connection structure that can both ensure the insulation board can be installed firmly and protect the integrity of the masonry wall structure to the greatest extent. Utility Model Content

It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of this utility model. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0023] Please see Figure 1-4This embodiment discloses a connection structure between an insulation board and a masonry wall, including a connecting component 3 for connecting the insulation board 2 to the masonry wall 1. The connecting component 3 includes 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. Multiple connecting rods 302 are spaced apart along the length direction of the masonry wall 1. The tie bars 301 extend through the masonry wall 1 itself along its length direction. One end of the connecting rod 302 near the insulation board 2 extends along the thickness direction of the masonry wall 1 to the insulation board 2. The insulation board 2 is fixedly connected to the connecting rods 302 by the fasteners 303. It is understood that the tie bars 301 are pre-embedded in the mortar joints of the masonry blocks during the masonry process to enhance the connection stability between the masonry wall 1 and the primary structure or structural columns of the building, and to improve the shear resistance of the masonry wall 1. During construction, tie bars 301 are arranged in multiple sets along the height of the wall, typically one set every two blocks. The number of tie bars 301 varies depending on the block width; in this embodiment, two tie bars 301 are used. The tie bars 301 extend through the masonry wall 1 along its length, effectively ensuring the connection stability between the masonry wall 1 and the building's 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 an embedded part in the primary structure, while the end closest to the structural column can extend into the structural column, becoming integrated with it during the column's pouring process. Tie bars 301 are typically made of steel bars, preferably with a diameter of 6-12mm, and their length is adapted to the length of the masonry wall 1. The length of the connecting rod 302 is determined based on the thickness of the masonry wall 1 and the insulation board 2. The fixing methods between the connecting rod 302 and the tie bar 301 include welding or snap-fit ​​connections. Fastener 303 can be self-tapping screws, nuts, chemical anchors, etc.

[0024] The aforementioned connection structure between the insulation board 2 and the masonry wall 1 ensures both secure installation of the insulation board 2 and maximizes the protection of the structural integrity of the masonry wall 1. By installing connecting rods 302 on the tie bars 301 of the masonry wall 1, non-destructive installation of the insulation board 2 is achieved, avoiding damage to the wall caused by traditional drilling processes and improving the wall's integrity and seismic performance. It also simplifies the construction process and meets green construction requirements. The tie bars 301 penetrate the wall and are vertically fixed to the connecting rods 302, forming a stable spatial force-bearing system. More specifically, it completely avoids drilling operations, eliminating micro-cracks and stress concentration problems caused by drilling; secondly, the connecting components 3 and masonry wall 1 are constructed simultaneously, resulting in better integrity and improved seismic performance; furthermore, the connecting rods 302 can be pre-fabricated, requiring only simple assembly on-site, thus increasing construction efficiency. This technical solution is particularly suitable for the construction of building exterior wall insulation systems with high seismic performance requirements.

[0025] In this embodiment, a first clamping plate 302a is fixedly provided at the end of the connecting rod 302 near the insulation board 2, and the first clamping plate 302a is respectively attached to the wall surface on the corresponding side of the upper and lower adjacent masonry blocks; a second clamping plate 302b is fixedly provided at the end of the connecting rod 302 away from the insulation board 2, and the second clamping plate 302b is respectively attached to the wall surface on the corresponding side of the upper and lower adjacent masonry blocks. Specifically, the first clamping plate 302a and the second clamping plate 302b are metal plates, which are welded and fixed to the connecting rod 302. This technical solution achieves bidirectional limiting and fixing of the masonry wall 1 by setting 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 sides of the upper and lower masonry blocks to form a clamping structure, which can effectively prevent the connecting rod 302 from shifting in the thickness direction of the masonry wall 1. More importantly, this two-way fixing method significantly improves the overall stability of the connecting component 3, the axial tension performance of the connecting rod 302 and the masonry wall 1 is good, and the stress concentration problem caused by the single-point force of traditional anchors is avoided.

[0026] In this embodiment, a leveling layer 4 is provided on the side of the masonry wall 1 near the insulation board 2, and the insulation board 2 is bonded to the leveling layer 4 with an adhesive. Specifically, the leveling layer 4 can be made of cement mortar or polymer mortar, with a thickness controlled within the range of 5-15mm. During construction, a scraper can be used to evenly apply the mortar to 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, with a recommended application thickness of 3-8mm. The insulation board 2 and the leveling layer 4 are bonded using a full-bonding method or a dot-frame method. This technical solution, by setting a leveling layer 4 between the masonry wall 1 and the insulation board 2, effectively solves the problem of hollowing and falling off of the insulation board 2 caused by unevenness of the masonry wall 1 in traditional construction. The setting of the leveling layer 4 allows the insulation board 2 to obtain a uniform support surface, improving the reliability of the bonding. Through the reasonable selection of adhesive and the control of construction technology, the long-term stability of the insulation board 2 can be ensured.

[0027] In this embodiment, the thickness of the first clamping plate 302a is equal to the thickness of the leveling layer 4. Specifically, the first clamping plate 302a is a metal plate located near the 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. This technical solution ensures that the outer surface of the clamping plate is flush with the finished surface of the leveling layer 4 by precisely matching the thickness of the first clamping plate 302a with the thickness of the leveling layer 4. In practice, the construction personnel can first install the connecting component 3 in place, use the first clamping plate 302a as a leveling reference, and control the plastering thickness of the leveling layer 4 through the outer surface of the clamping plate. This ensures that the leveling layer 4 can form a flat installation base with the first clamping plate 302a after construction, providing a good flatness guarantee for the subsequent bonding of the insulation board 2. Compared with the traditional construction method that requires a separate leveling reference, this solution integrates the leveling control and structural connection functions into the same component, which simplifies the construction process and improves the leveling accuracy.

[0028] In this embodiment, the first card plate 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 card plate 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 needs, 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 card plate 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 facilitates standardized production and on-site installation, which is conducive to improving construction efficiency; second, the arrangement 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 card plate 302a and the masonry wall surface; third, the planar structure of the rectangular plate is conducive to the uniform transfer of load and avoids local stress concentration. At the same time, the rectangular plate is conducive to the leveling construction of the leveling layer 4.

[0029] In this embodiment, a threaded hole 302b1 is provided at the geometric center of the first card plate 302a. The threaded hole 302b1 extends into the connecting rod 302 along the 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 machined to ensure the perpendicularity of the bolt during installation. This technical solution achieves the fixation of the insulation board 2 and the connecting rod 302 through threaded connection, which has significant advantages over the traditional drilling and anchoring method. The cooperation between the bolt and the threaded hole 302b1 provides stable axial tensile force, ensuring a tight fit between the insulation board 2 and the leveling layer 4. Since the connection 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 building scenarios with high seismic resistance requirements. During the threaded connection construction, only the bolt needs to be tightened, and the operation process does not cause impact vibration to the wall, which is conducive to maintaining the integrity of the masonry structure.

[0030] In this embodiment, the connecting rod 302 is provided with a connecting hole 302c, and the tie bar 301 passes through the connecting hole 302c and is welded and fixed to the connecting rod 302. The connecting hole 302c is a through hole penetrating the connecting rod 302, and its diameter is slightly larger than the diameter of the tie bar 301 to facilitate its 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 welded connection makes the tie bar 301 and the connecting rod 302 form an integral force-bearing system, which can effectively transfer horizontal loads and reduce stress concentration at the connection point.

[0031] In this embodiment, there are two tie bars 301, and the two tie bars 301 are arranged in parallel. Specifically, the arrangement of two tie bars 301 in parallel can effectively improve the overall stability of the connecting component 3. The two tie bars 301 extend parallel to each other along the length of the masonry wall 1, penetrating 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 connecting component 3 by setting two tie bars 301. Compared with a single tie bar 301, the arrangement of double tie bars 301 can better distribute 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.

[0032] In this embodiment, a connecting plate 5 is provided at one end of the tie bar 301, and the connecting plate 5 is welded and fixed to the two tie bars 301 respectively. Specifically, the connecting plate 5 is a metal plate, and its length direction is arranged perpendicular to the extension direction of the tie bar 301. This technical solution achieves a rigid connection at the ends of the two parallel tie bars 301 through the setting of the connecting plate 5. By setting the connecting plate 5, it is convenient to achieve a quick and reliable connection with the embedded parts in the primary structure of the building, thereby improving the convenience of construction.

[0033] The connection between the insulation board 2 and the masonry wall 1 can be constructed using the following steps: First, the connecting components 3 are prefabricated; then, the masonry wall 1 is constructed, with the tie bars 301 connecting to the corresponding embedded parts sequentially from bottom to top during the construction process; then, the leveling layer 4 is constructed using the first clamping plate 302a on the connecting rod 302; finally, the insulation board 2 is fixedly installed. In this construction method, the connection between the tie bars 301 and the embedded parts is completed simultaneously during the masonry process, ensuring the integrity and reliability of the connecting components 3. Using the first clamping plate 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 adhesive and mechanical fixing, ensuring the strength and durability of the connection. Therefore, this construction method is particularly suitable for areas with high seismic performance requirements, effectively reducing damage to the masonry wall 1 structure during construction and improving the overall seismic performance of the building.

[0034] Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
