Description

Technical Field

[0001] This utility model relates to the field of historical building renovation technology, specifically to the replacement of a fixed structure with deteriorated bricks on the exterior wall of a historical building. Background Technology

[0002] The historical building complex holds an important place in the history of China's modern industrial development. However, due to years of disrepair, weathering, and rain erosion, many parts of the exposed brick walls on the exterior facade are damaged. In particular, the blue brick structure of the exterior wall is severely damaged, which has destroyed the original appearance of the historical buildings and urgently needs to be restored.

[0003] When replacing and repairing deteriorated bricks, some vertical fasteners with fixing claws can be used. These claws are used to fix the bricks to the cavity in the wall, and mixed mortar is poured into the cavity for further fixation, preventing the bricks from falling off. However, this type of fixing mechanism requires drilling holes in the undeteriorated parts of the exterior wall of the historical building, which can damage the undeteriorated parts during the fixing process, thereby accelerating the subsequent deterioration of the undeteriorated parts and affecting the quality of the repair of the deteriorated exterior wall of the historical building. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a replacement for the fixed structure with the deteriorated bricks of the exterior wall of a historical building, without the need to drill holes or cause damage to the undeteriorated parts of the exterior wall of the historical building.

[0005] Technical solution: A partial replacement and fixing structure for deteriorated bricks on the exterior wall of a historical building, comprising a fixing component, wherein the fixing component includes a first fixing mechanism and a second fixing mechanism. One first fixing mechanism is installed on the left and right sides of the replacement brick, and one second fixing mechanism is installed on the upper and lower surfaces of the replacement brick. The first fixing mechanism engages and fixes the replacement brick with the gaps on the left and right sides of the original bricks on the exterior wall, and the second fixing mechanism engages and fixes the replacement brick with the gaps on the upper and lower sides of the original bricks on the exterior wall, thereby fixing the replacement brick in the gaps of the deteriorated bricks.

[0006] The first fixing mechanism includes a plurality of first fixing bars and a first connecting bar. The plurality of first fixing bars are arranged side by side and spaced apart. The first connecting bar is disposed in the middle of the plurality of first fixing bars for connection. The first fixing bar has an arc-shaped structure and is fixed to the wall surface of the replacement brick.

[0007] The second fixing mechanism includes several second fixing bars, several third fixing bars, and a second connecting bar. The several second fixing bars are arranged side by side and spaced apart. The second connecting bar is disposed in the middle of the several second fixing bars for connection. The several third fixing bars are arranged side by side and spaced apart. The second connecting bar is disposed in the middle of the several third fixing bars for connection. The second fixing bars and the third fixing bars are arc-shaped. The second fixing bars and the third fixing bars are horizontally corresponding and connected one-to-one. The second fixing bars and the third fixing bars are fixed to the surface of the replacement brick.

[0008] Furthermore, an adjusting rod is provided at the inner end of the second fixing strip, and a plug-in rod is provided at the inner end of the third fixing strip. The adjusting rod has a slot opened from its inner end face inward. The plug-in rod extends into the slot and is movably installed with the adjusting rod. The plug-in rod moves along the adjusting rod to adjust the connection length between the second fixing strip and the third fixing strip.

[0009] Ideally, the adjusting rod and the plug rod are flat to facilitate their insertion and relative movement adjustment.

[0010] Furthermore, a first fixing bolt is installed at the inner end of the adjusting rod, and a sliding groove is provided on the plug rod. By rotating the first fixing bolt, the plug rod is inserted into the sliding groove and fixed to the adjusting rod.

[0011] Furthermore, ear plates are provided at both ends of the first fixing strip, the outer end of the second fixing strip, and the outer end of the third fixing strip. A second fixing bolt is installed on the ear plate. By rotating the second fixing bolt, it extends into the connecting hole on the substitute brick, thereby fixing the first fixing mechanism and the second fixing mechanism to the substitute brick.

[0012] Ideally, the ear plate is flat to facilitate fixing to the replacement brick at this location using a second fixing bolt, resulting in a good fit.

[0013] Furthermore, the first and second fixing mechanisms are made of metal, possessing both structural strength and toughness. During the process of inserting the replacement brick into the gap of the deteriorated brick to be replaced, the arc-shaped first, second, and third fixing strips, when subjected to pressure on their surfaces, can withstand slight deformation and enter the gap between the replacement brick and the original brick of the building's exterior wall. Then, they recover a certain deformation in the gap to adaptively snap and fix themselves in the gap.

[0014] Beneficial effects: The advantages of this utility model are: it changes the existing embedded fixing structure to a snap-fit ​​fixing structure. The first and second fixing mechanisms of the fixing components are installed around the replacement brick. The first, second, and third fixing strips of the arc structure are snap-fitted and supported in the gap between the replacement brick and the deteriorated brick. It eliminates the need to drill and damage the undeteriorated bricks of the historical building's exterior wall, thus preserving the original appearance as much as possible and improving the repair quality of the deteriorated bricks of the historical building's exterior wall. The overall length of the second fixing mechanism, which is set on the largest surface of the replacement brick, can be adjusted to fit the length of the replacement brick, thereby improving the practicality of the fixing structure.

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0021] A method of partially replacing the fixed structure with deteriorated bricks on the exterior wall of a historical building, as shown in the attached figure. Figure 1 , 2 As shown, a fixing component 100 is installed on the replacement brick 200. The fixing component 100 includes a first fixing mechanism 110 and a second fixing mechanism 120. According to the contact surface when the exterior wall bricks are laid, a first fixing mechanism 110 is installed on the left and right walls of the replacement brick 200, and a second fixing mechanism 120 is installed on the upper and lower surfaces of the replacement brick 200, so that the fixing component 100 is installed around the replacement brick 200. The first fixing mechanism engages and fixes the replacement brick with the gaps on the left and right sides of the original exterior wall bricks, and the second fixing mechanism engages and fixes the replacement brick with the gaps on the upper and lower sides of the original exterior wall bricks, thus engaging and fixing the replacement brick in the gaps of the deteriorated bricks.

[0022] As attached Figure 3 , 4As shown, the first fixing mechanism 110 includes several first fixing bars 111 and first connecting bars 112. The several first fixing bars 111 are arranged side by side and spaced apart, and are connected by first connecting bars 112. The first fixing bars 111 have an arc-shaped structure, and each end of the first fixing bar 111 is provided with an ear plate 130. The ear plate 130 is flat and a second fixing bolt 131 is installed on the ear plate 130. A connecting hole 201 is opened on the wall surface of the replacement brick 200. The second fixing bolt 131 is rotated and inserted into the connecting hole 201 to tighten and fix the mechanism. After all the second fixing bolts on the ear plates are tightened, the first fixing mechanism is fixed to the wall surface of the replacement brick. The first fixing bars 111, the first connecting bars 112, and the ear plates 130 can be integrally formed.

[0023] As attached Figure 3 , 5 As shown, the second fixing mechanism 120 includes several second fixing bars 121, several third fixing bars 122, and a second connecting bar 123. The several second fixing bars 121 are arranged side by side and spaced apart, and are connected in the middle by a second connecting bar 123. The several third fixing bars 122 are arranged side by side and spaced apart, and are also connected in the middle by a second connecting bar 123. The second fixing bars 121 and the third fixing bars 122 are arc-shaped. The second fixing bars 121 and the third fixing bars 122 are laterally corresponding and connected one-to-one. The connecting ends are the inner ends of the second fixing bars 121 and the inner ends of the third fixing bars 122.

[0024] An adjusting rod 1211 is provided at the inner end of the second fixing bar 121, and a connecting rod 1221 is provided at the inner end of the third fixing bar 122. The adjusting rod 1211 and the connecting rod 1221 are flat. The adjusting rod 1211 has a slot opened inward from its inner end face. The connecting rod 1221 extends into the slot and is movably installed with the adjusting rod 1211. That is, the connecting rod 1221 moves along the adjusting rod 1211 in the slot to adjust the connection length of the second fixing bar 121 and the third fixing bar 122. A first fixing bolt 1212 is installed at the inner end of the adjusting rod 1211. A sliding groove 1222 is opened on the connecting rod 1221 along its length direction. The first fixing bolt 1212 is rotated to extend into the sliding groove 1222 and tightened to lock the connecting rod 1221, thus fixing the connecting rod 1221 onto the adjusting rod 1211. The lengths of all adjusting rods and connecting rods are adjusted to be consistent, and the first fixing bolt is used to tighten and lock them in place.

[0025] The outer ends of the second fixing strip 121 and the third fixing strip 122 are also provided with flat ear plates 130. Second fixing bolts 131 are also installed on the ear plates 130. Connecting holes 201 are also provided on the surface of the replacement brick 200. The second fixing bolts 131 are rotated and inserted into the connecting holes 201 for tightening. Once all the second fixing bolts on the ear plates are tightened, the second fixing mechanism is fixed to the surface of the replacement brick. The first fixing strip 121, the second connecting strip 123, the adjusting rod 1211, and the ear plates 130 can be integrally molded. Similarly, the third fixing strip 122, the second connecting strip 123, the plug rod 1221, and the ear plates 130 can be integrally molded.

[0026] The first fixing mechanism 110 and the second fixing mechanism 120 can be made of metal or rigid plastic, possessing both structural strength and toughness. During the process of inserting the replacement brick into the gap of the deteriorated brick to be replaced, the arc-shaped first fixing strip 111, second fixing strip 121, and third fixing strip 122, when subjected to surface pressure, can withstand slight deformation and enter the gap between the replacement brick and the original brick of the building's exterior wall. They then recover a certain deformation in the gap to adaptively snap and fix themselves in the gap. Both materials also allow for the creation of slots in the adjusting rod, grooves on the plug-in rod, and screw holes for installing the second fixing bolt. The ear plate 130 is flat to facilitate fixing to the replacement brick at this location using the second fixing bolt, providing a good fit. The adjusting rod and plug-in rod are flat to facilitate their insertion and relative movement adjustment.

[0027] The second fixing mechanism is installed on the surface along the length of the replacement brick. The fixing length can be adjusted according to the length of the replacement brick used in different building exterior walls. After the adjustment is completed, it is tightened and locked by the first fixing bolt, thereby improving the practicality of the fixing structure. In addition, the structure of the second fixing mechanism can reduce the pressure of the snap-fit ​​fixing and the uniformity of the force on each fixing strip on the second fixing mechanism.

[0028] After the replacement bricks are fixed in the gaps of the deteriorated bricks, the gaps between the replacement bricks and the exterior wall of the historical building can be filled with adhesive concrete to seal the gaps, thereby improving the repair quality of the deteriorated bricks on the exterior wall of the historical building.

[0029] This application proposes a method to partially replace the fixed structure with deteriorated bricks on the exterior walls of historical buildings. It can be used to connect a replacement brick with the surrounding original bricks, or to use an additional replacement brick when there are large gaps in the deteriorated bricks. The replacement bricks can be connected to each other or to the surrounding original bricks.

[0030] This application replaces the existing embedded fixing structure with a snap-fit ​​fixing structure for the damaged bricks on the exterior walls of historical buildings. The first and second fixing mechanisms of the fixing components are installed around the replacement bricks. The first, second, and third fixing strips of the arc-shaped structure are snap-fitted and supported in the gaps between the replacement bricks and the damaged bricks. This eliminates the need to drill and damage the undamaged bricks on the exterior walls of historical buildings, thus preserving the original appearance as much as possible and improving the repair quality of the damaged bricks on the exterior walls of historical buildings. The overall length of the second fixing mechanism, which is located on the largest surface of the replacement brick, can be adjusted to fit the length of the replacement brick, thereby improving the practicality of the fixing structure.
