Description

Technical Field

[0001] This utility model belongs to the technical field of brick self-locking structure, and specifically relates to a brick block self-locking structure. Background Technology

[0002] In the restoration and construction of historical and cultural buildings, it is essential to strictly adhere to the fundamental principle of not altering the original state of the cultural relic, maintaining its original appearance and characteristics, and preserving the era and regional features of the cultural relic as authentically and completely as possible. Therefore, the same mortar and wall blocks as the original walls are usually used during the restoration of ancient building walls. However, the mortar strength of the original wall construction is typically low, making it difficult to guarantee the seismic performance and stability requirements of the wall. Cracks often appear after restoration, requiring repeated repairs with short repair cycles. Therefore, it is necessary to use connecting structures between the brick masonry to reinforce the masonry.

[0003] Existing brick masonry connection structures are generally complex and inconvenient to construct, resulting in long construction periods. Furthermore, they are prone to causing uneven masonry walls after use, affecting the original appearance of historical and cultural buildings and hindering their restoration, thus having low practicality. Utility Model Content

[0004] In order to simplify the structure of the brick masonry connection mechanism, facilitate construction, shorten the construction period, and avoid the impact of the connection structure on the flatness of the masonry wall, this utility model provides a self-locking structure for brick blocks.

[0005] The technical solution of this utility model is as follows:

[0006] A self-locking structure for brick blocks, comprising:

[0007] A brick block having a long side for adjoining an adjacent brick block, wherein a tenon is provided on the long side of the brick block, recessed along the thickness and width directions of the brick block;

[0008] The tenon, a portion of which is designed to be fitted into the tenons of two adjacent brick blocks, is used to connect the two adjacent brick blocks.

[0009] Furthermore, at least two tenons are spaced apart on the long side of the brick block, and the centers of the two tenons are respectively located at the trisection points along the long side of the brick block.

[0010] Furthermore, the tenon body includes:

[0011] Two fitting parts, the two fitting parts being isosceles trapezoids with their upper bases adjacent, are used to fit into the tenons of two adjacent brick blocks and connect the two brick blocks.

[0012] A mortar joint is provided between the two fitting parts to connect the two fitting parts, and the two fitting parts are symmetrically arranged with respect to the mortar joint.

[0013] Furthermore, the two inner angles of the lower bottom of the fitting portion are 65-75°.

[0014] Furthermore, the length of the fitting portion along the short side of the brick block is 50-55 mm, and the width along the long side of the brick block is 30-35 mm; and / or,

[0015] The length of the mortar joint along the short side of the brick block is 15-20mm.

[0016] Furthermore, the tenon has a depth of 5-10mm along the thickness direction of the brick block and a length of 50-55mm along the short side direction of the brick block.

[0017] Furthermore, the thickness of the tenon is the same as the depth of the tenon.

[0018] Furthermore, the tenon is in the shape of an isosceles trapezoid, with the side closest to the center of the brick block being the long base and the side coinciding with the long side of the brick block being the short base.

[0019] Furthermore, structural adhesive is provided between the tenon and the tenon body to enhance the connection strength between them.

[0020] Furthermore, the structural adhesive is epoxy resin.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model discloses a self-locking structure for brick blocks. By using tenons and tenons on the brick blocks to self-lock and fix two adjacent brick blocks, the connection structure is simplified, construction is facilitated, and the construction period is effectively shortened. After the self-locking structure is used, its surface is flush with the surface of the brick blocks, which will not affect the original appearance of historical and cultural buildings and is more conducive to the restoration of historical and cultural buildings, thus improving practicality. When the masonry wall is repaired by the self-locking structure of this utility model, the geological energy is gradually dissipated through the friction between the bricks and the tenon and tenon joint, reducing the risk of wall collapse. Moreover, the tenon and tenon joint structure formed by the tenon and tenon distributes the load to the adjacent bricks, avoids stress concentration, and improves the compressive and shear resistance of the wall.

[0030] Example:

[0031] refer to Figures 1 to 3 This embodiment provides a brick block self-locking structure, including a brick block 1 and a tenon 3.

[0032] The brick block 1 has a long side for connecting with adjacent brick blocks 1. The material of the brick block 1 can be blue bricks used for the repair of ancient building walls. During the firing process, a mold with tenons 2 needs to be made to ensure that the brick block 1 and the tenon 3 can be connected to each other. Tenons 2 are recessed along the thickness and width directions of the brick block 1 on the long side. Preferably, at least two tenons 2 are spaced apart on the long side of the brick block 1, and the centers of the two tenons 2 are preferably located at three points on the long side of the brick block 1. At the joint, the depth of tenon 2 along the thickness direction of brick block 1 is 5-10mm. The depth of tenon 2 can be set according to the thickness of brick block 1. When brick block 1 is thicker, tenon 2 can be set deeper, such as 10mm. Conversely, the depth of tenon 2 is shallower, such as 5mm. The length along the short side of brick block 1 is 50-55mm. The length of tenon 2 can be set according to the length of the short side of brick block 1. This improves the connection strength while ensuring the strength of brick block 1 itself.

[0033] The tenon 3 is partially embedded in the tenon 2 of two adjacent brick blocks 1 to connect the two adjacent brick blocks 1. The brick blocks 1 are connected by the tenon 3, which reduces the cracking and peeling of mortar caused by freeze-thaw and weathering, extends the life of the wall, reduces the maintenance needs of traditional mortar masonry due to mortar aging, and allows for quick assembly, effectively improving construction efficiency. The thickness of the tenon 3 is the same as the depth of the tenon 2, so that after the tenon 3 connects two brick blocks 1, it is flush with the surface of the brick blocks 1 and will not affect the overall appearance of the masonry wall.

[0034] The brick block self-locking structure provided in this embodiment uses tenons 2 and tenons 3 to lock and fix two adjacent brick blocks 1 together, simplifying the connection structure, facilitating construction, and effectively shortening the construction period. After the self-locking structure of this utility model is used, its surface is flush with the surface of the brick block 1, which will not affect the original appearance of the historical and cultural building, and is more conducive to the restoration of the historical and cultural building, thus improving its practicality. During use, geological energy is gradually dissipated through the friction between the bricks and the tenon and tenon 3, reducing the risk of wall collapse. The tenon and tenon 3 form a tenon structure that distributes the load to the adjacent bricks, avoiding stress concentration and improving the wall's compressive and shear resistance.

[0035] In a preferred embodiment, the tenon 3 includes two fitting portions 301 and a mortar joint portion 302.

[0036] The two fitting portions 301 are isosceles trapezoids with their upper bases adjacent to each other. They are used to fit into the tenons 2 of two adjacent brick blocks 1, connecting the two brick blocks 1. The two interior angles of the lower base of the fitting portion 301 are 65-75°, preferably 70°. The length of the fitting portion 301 along the shorter side of the brick block 1 is 50-55mm, equal to the length of the tenon 2, preferably 50mm. The width along the longer side of the brick block 1 is 30-35mm, preferably 30mm. In other embodiments, the fitting portion 301 can also be other shapes, such as semicircular or semi-elliptical.

[0037] The mortar joint 302 is disposed between the two fitting parts 301 and is used to connect the two fitting parts 301. The two fitting parts 301 are symmetrically arranged with respect to the mortar joint 302. The length of the mortar joint 302 along the short side of the brick block 1 is 15-20mm, preferably 15mm. The mortar joint 302 provides a suitable amount of mortar filling redundancy between two adjacent brick blocks 1.

[0038] In a preferred embodiment, the tenon 2 is an isosceles trapezoid, with the side closest to the center of the brick block 1 being the long base and the side coinciding with the long side of the brick block 1 being the short base. The tenon 2 and the fitting part 301 are adapted to each other and are both isosceles trapezoids. Through the interlocking of the tenon 2, the fitting part 301 enables the bricks to form a natural self-locking mechanism in the horizontal and vertical directions, effectively resisting displacement or slippage caused by external forces (such as earthquakes and wind loads). When the tenon 3 is embedded in the tenon 2 to connect two adjacent brick blocks 1, the tenon 2 and the fitting part 301 are not easy to separate, making the connection between the brick blocks 1 more reliable.

[0039] As a preferred embodiment, structural adhesive is provided between the tenon 2 and the tenon body 3 to enhance the connection strength between the tenon 2 and the tenon body 3. Before the mating part 301 of the tenon body 3 is inserted into the tenon 2, structural adhesive is poured into the tenon 2. On the one hand, it can play a lubricating role, making it easier for the mating part 301 to be inserted into the tenon 2. On the other hand, after the structural adhesive solidifies, it can prevent the mating part 301 from easily detaching from the tenon 2, making the connection more secure. The structural adhesive can be epoxy resin.

[0040] During construction, the sides of two adjacent brick blocks 1 with tenons 2 are brought close together, structural adhesive is poured into the tenons 2, and then the tenon 3 is inserted so that the two fitting parts 301 of the tenon 3 are respectively embedded into the corresponding tenons 2 of the two brick blocks 1, connecting the two brick blocks 1. Then, mortar joints are poured between the two brick blocks 1, and the joints are made full. The above operation is repeated until the wall is completed.
