Technical Field
[0001] This utility model belongs to the field of ancient building maintenance technology, specifically a brick joint adjustment device for laying antique-style brick tiles. Background Technology
[0002] As important historical and cultural heritage, the repair and protection of ancient buildings are of paramount importance. Under the long-term erosion of wind, sun, and rain, the bricks in the walls of ancient buildings often suffer from localized damage such as efflorescence, peeling, and cracking. To preserve the authenticity and historical appearance of ancient buildings to the greatest extent possible, a "partial patching" method is usually adopted for repair. This involves carefully removing the damaged bricks to create a neat rectangular groove (or "groove"), and then filling it with bricks of similar material, size, and color.
[0003] In existing technologies, this brick-filling work mainly relies on manual labor, and the specific steps are as follows:
[0004] Grooving: Workers use traditional tools such as chisels and hammers to manually remove the damaged brick area, striving to form a rectangular groove with relatively straight edges and a size slightly larger than the new brick (to reserve space for the adhesive layer).
[0005] Brick preparation: Based on the dimensions of the groove, the new bricks are appropriately modified (such as cut or polished) to make them slightly smaller than the groove.
[0006] Brick pieces: Apply traditional adhesive materials (such as lime mortar, glutinous rice mortar, etc.) to the inner wall of the groove and the surface of the new brick, and then carefully embed the new brick into the groove.
[0007] Leveling and grouting: By tapping and observing, manually adjust the position of the new bricks to make their surface as flush as possible with the original wall surface, and use tools to fill the brick joints to make them look consistent with the original brick joints.
[0008] However, in practice, this traditional manual filling method requires that the gaps between the top and bottom of the new brick and the edge of the groove (i.e., the pre-reserved brick joints) be kept uniform after the new brick is embedded to coordinate with the original brick joints and achieve the effect of "restoring the old as before." But because the grooving process relies entirely on manual operation, it is difficult to accurately guarantee the flatness and verticality of the groove walls (especially the upper and lower walls). Furthermore, when embedding brick pieces, workers mainly rely on visual observation and feel to adjust the position. This purely manual operation method easily leads to visible unevenness in the gaps between the upper and lower sides of the brick pieces, or one side being too wide and the other too narrow, or even the brick pieces tilting. This not only seriously affects the overall aesthetics of the restored wall but also contradicts the principle of meticulousness and harmony in the restoration of ancient buildings. Utility Model Content
[0009] This utility model provides a brick joint adjustment device for laying antique-style brick tiles, in order to solve the defects in the prior art.
[0010] This utility model is achieved through the following technical solution:
[0011] A brick joint adjustment device for laying antique-style bricks includes a transparent rectangular plate. A through groove is provided on the front of the rectangular plate, and two parallel horizontal bars are provided in the through groove. The horizontal bars have threaded holes with opposite thread directions. A screw rod is threaded into the threaded hole. The inner ends of the two screw rods are coaxial and fixedly connected, and the outer ends are rotatably connected to the rectangular plate through bearings. A round hole is also provided on the horizontal bar, and a round rod fixedly set in the through groove is fitted into the round hole.
[0012] In use, a worker first attaches a rectangular plate to the wall, ensuring the through groove and the groove in the brick are directly opposite each other. Using a ruler, the worker ensures the horizontal center line of the through groove aligns with the horizontal center line of the groove. Then, the vertical height of the brick is measured, and a screw is rotated. Because the two threads on the horizontal bar are opposite, the rotation of the screw drives the two horizontal bars in opposite directions via a screw-driven sliding table principle. This ensures the distance between the two horizontal bars is equal to the vertical width of the brick. The brick is then placed between the two horizontal bars, and plaster is applied between the horizontal bars and the corresponding gaps in the grooves to achieve the same vertical gap between the bricks, ensuring overall aesthetics.
[0013] Preferably, the two ends of the crossbar are bent forward and respectively provided with a wire hole and a round hole.
[0014] Preferably, the rectangular plate has grooves on both sides of its rear side, and a vertical leveling plate is fixedly embedded in the grooves. The rear sides of the arc-shaped rod and the horizontal rod are on the same plane as the rear side of the rectangular plate, and the length of the leveling plate is greater than the vertical width of the rectangular plate. The fact that the rear side of the horizontal rod is on the same plane as the rear side of the rectangular plate ensures that the bonded bricks are on the same plane as the original bricks, further guaranteeing aesthetics. The leveling plate, by extending vertically to level multiple wall bricks, achieves further leveling.
[0015] Preferably, a fixing block is fixedly connected to the rear side of the crossbar near its end. The fixing block is vertically connected to a telescopic rod with a locking function. The locking support rod ensures that even without measurement, when the telescopic rod is placed in the groove and moves synchronously and in opposite directions, the distance between the two crossbars and the groove is the same. The telescopic rod can adjust the distance between the crossbar and the groove while ensuring that the distance between the crossbar and the inner wall of the corresponding top and bottom surfaces of the groove is the same, so as to meet the requirements of the brick width between the two crossbars.
[0016] Preferably, the rectangular plate has a vertically oriented through hole that communicates with the through slot. A rotating shaft is coaxially fixedly connected to the opposite ends of the lead screw. The rotating shaft passes through the through hole and is rotatably connected to the through hole via a bearing. A rotating handle is provided at the outer end of each rotating shaft. The rotating handle facilitates the rotation of the rotating shaft, which in turn drives the lead screw to rotate.
[0017] The beneficial effects of this utility model are as follows: By adjusting the two horizontal bars synchronously and in the same direction, the spacing between the brick joints formed by the distance between the two horizontal bars and the inner walls of the top and bottom surfaces corresponding to the groove is the same, thereby ensuring that the spacing between the upper and lower brick joints is the same when placing brick pieces, thus ensuring the overall aesthetics.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] A brick joint adjustment device for laying antique-style brick tiles, such as Figure 1 and Figure 2As shown, it includes a transparent rectangular plate 1. The rectangular plate 1 has a through groove 2 that runs from front to back. Two parallel crossbars 3 are provided in the through groove 2. The two ends of the crossbars 3 are bent forward and have threaded holes and round holes respectively. The threads of the two crossbars 3 are in opposite directions. A lead screw 5 is threaded into the threaded hole. The inner ends of the two lead screws 5 are coaxial and fixedly connected. The outer ends are rotatably connected to the rectangular plate 1 through bearings. A round rod 6 is fixedly installed in the through groove 2 and fitted into the round hole.
[0025] In use, a worker first attaches a rectangular plate 1 to the wall, ensuring that the through groove 2 and the groove of the brick are directly opposite each other. Using a ruler, the worker ensures that the horizontal center line of the through groove 2 aligns with the horizontal center line of the groove. Then, the vertical height of the brick piece 4 is measured, and the screw rod 5 is rotated. Because the two threads on the crossbar 3 are opposite, the rotation of the screw rod 5, through the principle of the screw rod 5 driving the slide table, moves the two crossbars 3 in opposite directions. This ensures that the distance between the two crossbars 3 is equal to the vertical width of the brick piece 4. The brick piece 4 is then placed between the two crossbars 3, and plaster is applied between the crossbars 3 and the corresponding gaps in the grooves to ensure that the gaps between the brick pieces 4 are the same vertically, guaranteeing overall aesthetics.
[0026] The rectangular plate 1 has grooves on both sides of its rear side, and a vertical leveling plate 7 is fixedly embedded in the grooves. The rear sides of the arc-shaped rod and the horizontal bar 3 are on the same plane as the rear side of the rectangular plate 1. The length of the leveling plate 7 is greater than the vertical width of the rectangular plate 1. The fact that the rear side of the horizontal bar 3 is on the same plane as the rear side of the rectangular plate 1 ensures that the bonded brick 4 is on the same plane as the original brick, further guaranteeing its aesthetics. The leveling plate 7, by extending vertically to level multiple wall bricks, achieves further leveling.
[0027] A fixing block 9 is fixedly connected to the rear side of the crossbar 3 near its end. The fixing block 9 is vertically connected to a telescopic rod 10 with a locking function. The locking support rod ensures that even without measurement, the telescopic rod 10 can be placed in the groove and moved synchronously and in opposite directions, ensuring that the distance between the two crossbars 3 and the groove is the same. The telescopic rod 10 can adjust the distance between the crossbar 3 and the groove while ensuring that the distance between the crossbar 3 and the inner wall of the corresponding top and bottom surfaces of the groove is the same, so as to meet the width requirements of the brick piece 4 between the two crossbars 3.
[0028] The rectangular plate 1 has a vertically oriented through hole that communicates with the through slot 2. A rotating shaft 8 is coaxially fixedly connected to the opposite end of the lead screw 5. The rotating shaft 8 passes through the through hole and is rotatably connected to the through hole via a bearing. A rotating handle is provided at the outer end of each rotating shaft 8. The rotating handle facilitates the rotation of the rotating shaft 8, which in turn drives the lead screw 5 to rotate.
[0029] The use of this application can ensure that the distance between the two horizontal bars 3 and the inner wall of the top and bottom surfaces corresponding to the groove is the same by adjusting the two horizontal bars 3 in a synchronous and directional manner. This ensures that when placing the brick pieces 4, the upper and lower widths of the brick joints are the same, thereby ensuring the overall aesthetics.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
