Description
Technical Field
[0001] This invention relates to the field of ancient building brick wall repair technology, and more specifically, to a repair device and method for ancient building brick walls. Background Technology
[0002] Chinese traditional architecture possesses rich historical connotations, representing a precious cultural heritage and a vital carrier of traditional culture. "A thousand-mile dike can be breached by an ant hole," highlighting the crucial role of restoration in ensuring the longevity of ancient buildings. As the concepts of protecting cultural heritage and promoting traditional culture gain wider acceptance, ancient buildings across the country are being repaired. However, this surge in renovation and reconstruction has also brought with it a constant stream of controversies.
[0003] Common problems with ancient building brick walls include efflorescence and minor breakage, generally caused by weathering, dampness, or external damage. For localized efflorescence or damage, the surface layer can be removed to expose the hard parts of the bricks. Depending on the depth of the damage, brick pieces or blocks can be cut to the shape on-site and then firmly bonded to the wall. After drying, grouting can be done to make it consistent with the overall structure. Although this method is simple and convenient, the connection between the bricks and the wall is not strong enough, resulting in poor stability and unsatisfactory repair effects. Therefore, this invention provides a device and method for repairing ancient building brick walls. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a repair device and method for ancient building brick walls, which solves the problem of insufficient firmness between the patched bricks and the wall.

[0006] A further preferred embodiment is that the insertion rod includes an outer tube, an inner rod, a positioning plate, and a slider; The outer tube is sleeved on one end of the inner rod, and the inner rod and the outer tube are rotatably engaged. A first blind hole is opened on the back of the brick, and the outer tube is fixed in the first blind hole. The positioning plate and the slider are both fixed on the outer surface of the inner rod. The slider is located on the side of the positioning plate away from the brick. The end of the inner rod away from the outer tube is used to extend into the insertion tube and is positioned and locked by the positioning plate.
[0007] A further preferred embodiment is that the insertion tube includes a tube body and a gripping plate, the gripping plate being located between the brick and the brick wall, and the gripping plate being fixed to the outer surface of the tube body.
[0008] A further preferred embodiment includes a spring and a push plate; A second blind hole is provided in the brick wall, the tube is fixed in the second blind hole, the spring and the push plate are both located in the tube, one end of the spring is fixed to the push plate, and the other end is fixed to the bottom of the tube, and the push plate is used to contact the end face of the inner rod; The inner wall of one end of the tube body is provided with a guide groove adapted to the slider. The guide groove includes a first horizontal groove, an arc groove and a second horizontal groove connected in sequence. The length direction of the first horizontal groove and the second horizontal groove are consistent with the axial direction of the tube body. The slider slides in cooperation with the first horizontal groove, the arc groove and the second horizontal groove. A notch is provided on one side of the pipe body opening, and a limiting port for accommodating the positioning plate is provided on one side of the notch. The limiting port is located on the side of the gripping plate away from the brick.
[0009] A further preferred embodiment is that: a plurality of first gripping rods are evenly distributed on the circumferential surface of the outer tube, and the outer tube is fixed in the first blind hole by cement pouring.
[0010] A further preferred embodiment is that: multiple second gripping rods are evenly distributed on the circumferential surface of the tube body, and the tube body is fixed in the second blind hole by cement pouring.
[0011] A further preferred embodiment is that: multiple gripping plates are provided, and the multiple gripping plates are equally spaced around the perimeter of the pipe body, with the notches provided between adjacent gripping plates.
[0012] A further preferred embodiment is that at least two positioning plates are provided, and the limiting port corresponds one-to-one with the positioning plate.
[0013] A method for repairing the brick walls of ancient buildings includes the following steps: S1. Original wall treatment: Remove the peeling and broken parts of the brick wall surface to expose the hard parts of the bricks, so as to form a filling hole for brick replacement. S2.

As the inner rod continues to push in, the slider will enter the first horizontal groove. At this time, the positioning plate is located in the notch. When the slider enters the arc-shaped groove, the inner rod will drive the positioning plate to rotate, so that the positioning plate rotates into the limiting opening. When the slider enters the connection between the arc-shaped groove and the second horizontal groove, under the action of the spring, the slider will automatically enter the second horizontal groove. At this time, the slider will be locked in the second horizontal groove, and the positioning plate will be locked in the limiting opening, thereby installing the brick on the brick wall through the insertion rod and the insertion tube. When the brick is inserted into the filling opening, the mortar will be automatically squeezed to the gripping plate. After the mortar solidifies, the gripping plate can provide a good gripping force.
[0016] This invention, through the combination of insert rods and tubes and the bonding effect of mortar, solves the problem of insufficient connection between the patched bricks and the wall, and is suitable for the repair of localized efflorescence or damage to the brick walls of ancient buildings.

The inner wall of one end of the tube body 71 is provided with a guide groove adapted to the slider 65. The guide groove includes a first horizontal groove 751, an arc groove 752, and a second horizontal groove 753 connected in sequence. The lengths of the first horizontal groove 751 and the second horizontal groove 753 are aligned with the axial direction of the tube body 71. The slider 65 slides in conjunction with the first horizontal groove 751, the arc-shaped groove 752, and the second horizontal groove 753. The arc-shaped groove 752 is arc-shaped along the circumference of the tube body 71, with one end connected to the end of the first horizontal groove 751 away from the gripper plate 74, and the other end extending towards the bottom of the tube body 71 and connecting to the end of the second horizontal groove 753 away from the gripper plate 74. The first horizontal groove 751, the arc-shaped groove 752, and the second horizontal groove 753 have a smooth transition. To improve the adhesion between the brick 2 and the brick wall 1 through mortar bonding, it is preferable that the second horizontal groove 753 not be too long.
[0023] Preferably, a notch 76 for the positioning plate 64 to pass through is provided on one side of the pipe body 71.

[0024] A method for repairing the brick walls of ancient buildings, such as Figure 1-7 As shown, it includes the following steps: S1. Original wall treatment: Remove the peeling and broken parts of the brick wall 1 to expose the hard parts of the brick 2, so as to form a filling opening for the filling of the brick 2; S2. Filling port treatment: Trim the filling port to make it square and as flat as possible. Then, open a second blind hole 5 at the bottom of the filling port and insert the tube into the second blind hole 5. Pour cement into the second blind hole 5. After the cement solidifies, fix the tube in the second blind hole 5. S3. Treatment of patching brick 2: Cut brick 2 for patching the filling opening according to the shape of the filling opening, then open a first blind hole 4 on the back of brick 2 corresponding to the position of the second blind hole 5, and insert the rod 6 into the first blind hole 4; adjust the position of the rod 6 so that the slider 65 on the rod 6 corresponds to the first horizontal groove 751 on the tube body 71, and then pour cement into the first blind hole 4. After the cement solidifies, the rod 6 is fixed in the first blind hole 4. S4. Patch: Apply mortar to the back of the treated brick 2. When laying the mortar, avoid the insert rod 6, positioning plate 64 and slider 65. Then align the inner rod 62 with the tube body 71 and patch the brick 2 into the filling opening. When the brick 2 is patched into the filling opening, the mortar will be automatically squeezed to the grab plate 74.
[0025] S5. Grouting: After the mortar on the back of brick 2 dries, grout the mortar around brick 2.
[0026] In this invention, when brick 2 is inserted into the filling opening, inner rod 62 extends into tube 71 and pushes push plate 73 away from brick 2. As inner rod 62 continues to push in, slider 65 enters the first horizontal groove 751. At this time, positioning plate 64 is located in notch 76. When slider 65 enters arc groove 752, inner rod 62 will drive positioning plate 64 to rotate, so that positioning plate 64 rotates into limiting opening 77. When slider 65 enters the connection between arc groove 752 and second horizontal groove 753, under the action of spring 72, slider 65 will automatically enter second horizontal groove 753. At this time, slider 65 will be locked in second horizontal groove 753, and positioning plate 64 will be locked in limiting opening 77, thereby installing brick 2 on brick wall 1 through insertion rod 6 and insertion tube. When brick 2 is inserted into the filling opening, mortar will be automatically squeezed to gripping plate 74. After the mortar solidifies, gripping plate 74 can provide good gripping force.
