Description

Technical Field

[0001] The invention relates to the field of wall reinforcement, and in particular to an integral reinforcement structure and an integral reinforcement method for a pavilion-type brick-built ancient tower. Background Art

[0002] The pavilion-style brick-built ancient pagodas are an important historical and cultural heritage of China, with profound historical, artistic and scientific value. However, after experiencing long-term erosion by wind and rain, natural disasters and the impact of human activities, these ancient pagodas have gradually exposed a series of diseases. According to the nature and scope of the disease, the disease of the ancient pagoda can be divided into two categories: local damage and overall damage.

[0003] Local damage usually manifests itself in loose bricks, local cracks, and surface weathering. Due to long-term weathering, some bricks and mortar joints of some ancient towers have weathered and peeled off, and some bricks have become loose. Although these local looseness will not immediately lead to the collapse of the entire ancient tower, if not repaired in time, it may affect the long-term safety of the tower.

[0004] The overall damage is mainly manifested in the overall tilt of the tower and long cracks. After experiencing multiple earthquakes, some ancient towers have experienced uneven foundation settlement, resulting in serious tilt of the tower and expansion of cracks. The tower structure can no longer withstand further deformation, and the overall safety of the tower is seriously challenged. The overall damage seriously threatens the safety and durability of the ancient tower, and the tower structure needs to be reinforced and repaired.

[0005] At present, there are two ways to repair and strengthen the tower body: external reinforcement and internal reinforcement. External reinforcement is to set up a steel frame or other materials on the outside of the tower body to strengthen the tower wall structure; internal reinforcement is to set up a steel frame inside the tower body to support the tower body. Since external reinforcement is simple to construct, most of the repair and reinforcement of existing ancient towers adopt the external reinforcement method. However, in external reinforcement, exposed steel components are prone to rust, and carbon fiber cloth or glass fiber reinforced plastic (GFRP) hoops and tower bodies are prone to debonding. The steel frames in the existing internal reinforcement methods are basically arranged in layers, and there is a lack of effective connection between the reinforcement bodies, resulting in poor integrity. Summary of the invention

[0006] In order to overcome the above-mentioned deficiencies existing in the existing ancient building restoration and reinforcement process, the technical problem to be solved by the present invention is to provide an overall reinforcement structure and an overall reinforcement method for a pavilion-type brick masonry ancient tower, which can realize overall reinforcement of the tower body.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0009] Furthermore, a fixed pile extending into the foundation is provided below the column located at the bottom layer, and an embedded bolt is provided at the upper end of the fixed pile. The column is an I-beam, and a fixed plate is provided at the lower end thereof, and is fixedly connected to the embedded bolt via the fixed plate.

[0010] Furthermore, the interlayer connecting parts include connecting steel columns, and end steel plates and connecting bolts respectively arranged at the upper and lower ends of the connecting steel columns. A platform steel plate is provided on the top of the column. The connecting steel columns are inserted into through holes drilled in the floor slabs. The connecting bolts at the lower ends thereof are passed through the through holes on the platform steel plates and fixedly connected to the platform steel plates by nuts. The fixing plate at the lower end of the upper column is connected to the end steel plate by bolts.

[0011] Furthermore, a frame beam is respectively connected to the column top and the column bottom of two adjacent columns, and a diagonal brace is connected between the column top of one column and the column bottom of the other column.

[0012] Furthermore, the cross beam and frame beam are both C-shaped steels, wherein the openings of the upper and lower frame beams are opposite, the opening of the cross beam faces away from the wall, and the web of the cross beam is provided with a connecting hole for the through-wall screw to pass through.

[0013] Furthermore, tie bars are provided between the frame beam and the cross beam, and between two adjacent cross beams, and the adjacent upper and lower tie bars are staggered with each other in the vertical direction.

[0014] Furthermore, the clamping part is a cross-shaped steel clamp plate with a width greater than the mortar joint, a threaded hole is provided in the middle of the steel clamp plate, the through-wall screw is arranged at the intersection of the longitudinal and transverse mortar joints, the outer end of the through-wall screw is threadedly connected to the threaded hole of the steel clamp plate, and a serrated surface is provided on the surface of the steel clamp plate in contact with the wall.

[0015] Furthermore, the clamping member is a claw-type clamp, which includes a fixed block and a plurality of pressure strips arranged around the fixed block, and the ends of the pressure strips are provided with pins that can be inserted into the mortar joints of the wall.

[0016] Furthermore, the fixing blocks and the pressure strips are rectangular strip structures that match the size and direction of the wall mortar joints.

[0017] The overall reinforcement method for the pavilion-type brick masonry ancient tower comprises the above-mentioned overall reinforcement structure for the pavilion-type brick masonry ancient tower, and further comprises the following steps:

[0018] Step 1: According to the specific structure of each layer of the ancient pagoda, determine the location of the columns along the inner wall of the wall, as well as the height and model of the columns corresponding to each layer, and make corresponding beams according to the distance between two adjacent columns and the shape of the wall;

[0019] Step 2: Install the columns on the bottom layer, make sure the bottom end of the columns is firmly connected to the foundation, then confirm the positions of all external reinforcement parts on the bottom layer, drill holes in the wall mortar joints at the corresponding positions, and then insert through-wall screws into the holes, fix the outer ends of the through-wall screws to the clamping parts outside the wall, and temporarily connect the inner ends to the beams inside the wall through nuts.

[0020] Step 3: First, fix the two ends of the beam to the columns, then tighten the nuts connecting the through-wall screws and the beams, and use the through-wall screws and the clamps to press the wall against the beams;

[0021] Step 4: After the bottom layer is reinforced, first drill holes at the positions corresponding to the second layer floor slab and the bottom layer columns, then insert interlayer connectors into the drilled holes, and fix the lower ends of the interlayer connectors to the upper ends of the bottom layer columns, then fix the lower ends of the second layer columns to the upper ends of the interlayer connectors, and finally reinforce the wall in the manner of steps 2 and 3;

[0022] Step 5. According to step 4, follow the principle of bottom-up, after the reinforcement of one layer is completed, the upper wall will be reinforced until the reinforcement work of the entire ancient tower is completed.

[0023] The beneficial effects of the present invention are:

[0024] The present invention adopts a combination of internal reinforcement and external reinforcement to reinforce the ancient pagoda as a whole. This dual reinforcement strategy not only ensures the stability of the internal structure of the ancient pagoda, but also takes into account the reinforcement requirements of the external wall, achieving a coordinated reinforcement effect between the inside and the outside.

[0025] In terms of internal reinforcement, the connection between the upper and lower floor columns is achieved through interlayer connectors, and the entire structure is connected into a stable whole using beams. This not only enhances the stability of the internal reinforcement structure itself, but also realizes the interlaced connection between the columns and the floor slabs through interlayer connectors, further improving the stability of the internal structure of the ancient tower.

[0026] In terms of external reinforcement, multiple through-wall screws are arranged in an array, and the wall is clamped by tightening the clamping parts with a smaller area. This external reinforcement method has little impact on the appearance of the ancient tower, and can effectively enhance the stability of the wall and ensure the firmness of the overall structure of the ancient tower.

[0027] The present invention can firmly fix the wall and floor of the ancient pagoda on the steel structure through the organic combination of internal reinforcement and external reinforcement, thereby significantly improving the overall reinforcement effect of the ancient pagoda and providing a strong guarantee for the long-term protection and use of the ancient pagoda.

DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the accompanying drawings.

[0041] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not specific to the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0042] like Figure 1-3 As shown, the present invention provides an integral reinforcement structure for a pavilion-type brick masonry ancient tower, comprising an inner reinforcement member 1 and an outer reinforcement member 2, wherein the inner reinforcement member 1 comprises a plurality of columns 11 arranged at intervals along the circumferential direction of the inner wall of the ancient tower 3, wherein the lower end of the column 11 located at the bottom floor is fixedly connected to the foundation, and in the remaining floors, the lower end of the column 11 of the upper floor is fixedly connected to the upper end of the column 11 of the lower floor through the interlayer connector 4 passing through the floor slab of the corresponding floor, and a plurality of beams 12 are arranged at intervals along the vertical direction between two adjacent columns 11 of each floor; the outer reinforcement member 2 comprises a clamping member 21 and a through-wall screw 22 arranged in an array, the clamping member 21 is located on the outer wall of the wall of the ancient tower 3, the outer end of the through-wall screw 22 is fixedly connected to the clamping member 21, and the inner end of the through-wall screw 22 is connected to the cross beam 12 through a nut after passing through a through hole drilled along the mortar joint of the wall, so that the wall is clamped between the clamping member 21 and the cross beam 12. To ensure the structural strength, the inner reinforcement member 1 and the outer reinforcement member 2 are both made of steel structure and are treated with rust prevention. Only the pressing member 21 of the entire reinforcement structure is exposed to the outside, and it can be painted with an anti-corrosion paint that is consistent with the color of the wall of the ancient tower 3, which can not only prevent rust and corrosion of the pressing member exposed to the outside of the tower body, increase its durability, but also reduce the impact on the overall appearance of the ancient tower 3.

[0043] The present invention is mainly used for the overall reinforcement of the ancient tower 3, rather than the reinforcement of the wall alone. Therefore, it is necessary to ensure the integrity of the internal reinforcement 1 first. The present invention adopts the method of interlacing and setting interlayer connectors 4 on the floor slab to connect the upper column 11 and the lower column 11, and combines all the columns 11 into a whole through multiple beams 12 between two adjacent columns 11 to form a steel frame, thereby ensuring the stability of the entire internal reinforcement 1. At the same time, the interlaced connection between the column 11 and the floor slab is realized through the interlayer connector 4, which improves the stability of the internal structure of the ancient tower 3. After the internal steel frame is determined, external reinforcement can be carried out. In terms of external reinforcement, the present invention adopts an array of multiple through-wall screws 22 to tighten the clamping member 21 with a smaller area to clamp the wall to the internal steel frame. The present invention can firmly fix the wall and floor of the ancient tower 3 on the steel structure through the organic combination of the internal reinforcement member 1 and the external reinforcement member 2, thereby significantly improving the overall reinforcement effect of the ancient tower 3 and providing a strong guarantee for the long-term protection and use of the ancient tower 3.

[0044] In order to ensure the stability of the inner reinforcement 1 in the vertical direction, a fixed foundation pile 5 extending into the foundation is provided below the column 11 at the bottom layer, and an embedded bolt 51 is provided at the upper end of the fixed foundation pile 5. The column 11 is an I-beam, and a fixing plate 13 is provided at the lower end thereof, and is fixedly connected to the embedded bolt 51 through the fixing plate 13. The fixed foundation pile 5 is constructed by drilling a hole first and then pouring reinforced concrete in the hole. According to the height of the ancient tower 3 and the foundation conditions, the fixed foundation pile 5 can be set to 5 to 8 meters, and the diameter is determined according to the model of the column 11, and it can be no less than the longest side of the I-beam cross section.

[0045] For the interlayer connector 4, the solution adopted by the present invention is as follows: Figure 4-6As shown, the interlayer connector 4 includes a connecting steel column 41, and an end steel plate 42 and a connecting bolt 43 respectively arranged at the upper and lower ends of the connecting steel column 41. A platform steel plate 14 is arranged on the top of the column 11. The connecting steel column 41 is inserted into the through hole drilled in the floor slab. The connecting bolt 43 at the lower end thereof passes through the through hole on the platform steel plate 14 of the lower column 11 and is fixedly connected to the platform steel plate 14 through a nut. The fixing plate 13 at the lower end of the upper column 11 is connected to the end steel plate 42 through bolts. The size of the connecting steel column 41 is designed according to the load-bearing conditions. The drilled hole on the floor slab is equivalent to the outer diameter of the connecting steel column 41. After the connecting steel column 41 is fixed to the lower column 11, the gap between the connecting steel column 41 and the drilled hole can be filled with concrete or other fillers to prevent the column 11 from shaking. When installing the interlayer connector 4, first pass the connecting steel column 41 through the drilled hole from top to bottom, so that the connecting bolt 43 at the lower end passes through the through hole on the platform steel plate 14 until the lower end of the connecting steel column 41 contacts the platform steel plate 14, and then use the nut connected to the connecting bolt 43 to lock the connecting steel column 41 on the platform steel plate 14, and finally use bolts to connect the fixing plate 13 of the upper column 11 to the end steel plate 42 at the top of the interlayer connector 4.

[0046] Since the external reinforcement 2 needs to be set according to the wall conditions during the reinforcement process, the position of the corresponding crossbeam 12 of the internal reinforcement 1 is not fixed. In particular, some walls with window openings need to be flexibly set to avoid the window openings. Therefore, the crossbeam 12 is generally fixed to the column 11 after connecting the through-wall screw 22. Therefore, in order to ensure the stability of the column 11 before constructing the external reinforcement 2, a frame beam 15 can be respectively connected to the top and bottom of two adjacent columns 11 to connect the two columns 11 to form a frame, and a diagonal brace 16 is connected between the top of one column 11 and the bottom of the other column 11 to avoid deformation of the frame, thereby providing a stable steel structure foundation for the subsequent construction of the external reinforcement 2. Figure 6 As shown, external threads can be processed at both ends of the diagonal brace 16, and then connected to the mounting seat 19 on the column 11 through nuts, so as to facilitate the adjustment of the tensioning force.

[0047] Specifically, Figure 7 As shown, the cross beam 12 and the frame beam 15 are both C-shaped steels, wherein the openings of the upper and lower frame beams 15 are opposite, the opening of the cross beam 12 faces away from the wall, and the web of the cross beam 12 is provided with a connection hole 17 for the through-wall screw 22 to pass through. The connection hole 17 can be processed on site according to the position of the through-wall screw 22, and the cross beam 12 does not have to be arranged horizontally, and can be arranged according to actual conditions so as to be connected with more through-wall screws 22. The cross beam 12 can be fixed to the column 11 by welding, or an end plate can be provided at the end of the cross beam 12, and then connected to the column 11 by bolts.

[0048] Further, such as Figure 7 As shown, a tie bar 18 is connected between the frame beam 15 and the cross beam 12, and between two adjacent cross beams 12, and the adjacent upper and lower tie bars 18 are staggered in the vertical direction. The tie bars 18 can be stud bolts, connected to the cross beam 12 through nuts, and the number of tie bars 18 between two adjacent cross beams 12 is determined according to the length of the cross beam 12, and is set at a uniform interval as a reference. The horizontal staggering of the upper and lower tie bars 18 is conducive to dispersing the force and improving the seismic performance.

[0049] Regarding the structural form of the pressing member 21 of the external reinforcement member 2, the present invention provides the following three structural forms:

[0050] Option 1: If Figure 8 , Fig. 9 As shown, the clamping member 21 is a cross-shaped steel clamping plate with a width greater than the mortar joint of the wall. A threaded hole 23 is provided in the middle of the steel clamping plate. The through-wall screw 22 is provided at the intersection of the vertical and horizontal mortar joints. The outer end of the through-wall screw 22 is threadedly connected with the threaded hole 23 of the steel clamping plate. The surface of the steel clamping plate in contact with the wall is provided with a serrated surface 24. The steel clamping plate of this scheme is small in size and cross-shaped. After the array is set, it is similar to the mortar joint structure and is not easy to detect. Combined with the same color painting, it has little impact on the appearance of the wall. However, the tensioning area is small, the number of arrays required will be large, and the construction is more troublesome.

[0051] Option 2: If Fig.10 As shown, the clamping member 21 is a claw-type clamping plate, including a fixed block 25 and a plurality of pressure strips 26 arranged around the fixed block 25. A threaded hole 23 that can be connected to the through-wall screw 22 is provided in the middle of the fixed block 25, and a pin 27 that can be inserted into the mortar joint of the wall is provided at the end of the pressure strip 26. The advantage of this structural form is that the pressure strip 26 and the pin 27 can be used to tighten multiple wall tiles, thereby reducing the number of drilling holes. The disadvantage is that it has a certain impact on the appearance of the wall.

[0052] Option 3: If Fig.11 As shown, the fixing block 25 and the pressure strip 26 are rectangular strip structures that match the size and direction of the wall mortar joint. This structural form combines the advantages of solution one and solution two, can reduce the number of through-wall screws 22, improve construction efficiency, and have little impact on the wall appearance of the ancient tower 3.

[0053] According to the above reinforcement structure, the present invention also provides an overall reinforcement method for a pavilion-type brick masonry ancient tower, comprising the following steps:

[0054] Step 1: According to the specific structure of each layer of the ancient pagoda 3, determine the arrangement position of the columns 11 along the circumference of the inner wall, as well as the height and type of the columns 11 corresponding to each layer, and make corresponding crossbeams 12 according to the distance between two adjacent columns 11 and the shape of the wall. Usually, the size of the lower column 11 is larger and the upper one is smaller, so as to reduce the deadweight of the internal fixing 1;

[0055] Step 2: Install the columns 11 of the bottom layer, ensure that the lower end of the column 11 is firmly connected to the foundation, then confirm the positions of all the external reinforcement members 2 required for the bottom layer, drill holes in the wall mortar joints at the corresponding positions, and then insert the through-wall screws 22 into the drilled holes, and fix the outer ends of the through-wall screws 22 to the clamping members 21 outside the wall, and temporarily connect the inner ends to the beams 12 inside the wall through nuts to indicate the approximate positions of the beams 12. For those that need to construct fixed foundation piles 5, first construct the fixed foundation piles 5 and then install the columns 11;

[0056] Step 3: First, fix the two ends of the beam 12 to the column 11, and then tighten the nut connecting the through-wall screw 22 and the beam 12, and use the through-wall screw 22 and the clamping member 21 to press the wall against the beam 12 to achieve a stable connection between the outer reinforcement 2 and the inner reinforcement 1;

[0057] Step 4: After the bottom layer is reinforced, first drill holes at the positions corresponding to the second-layer floor slab and the bottom-layer columns 11, and then insert the interlayer connector 4 into the drilled holes. The lower end of the interlayer connector 4 is fixedly connected to the upper end of the bottom-layer column 11, and then the lower end of the second-layer column 11 is fixed to the upper end of the interlayer connector 4. Finally, the wall is reinforced according to the methods of steps 2 and 3.

[0058] Step 5. According to steps 2 to 4, follow the principle of bottom-up, after the reinforcement of one layer is completed, the upper wall will be reinforced until the reinforcement work of the entire ancient tower 3 is completed.

[0059] In summary, the overall reinforcement structure and overall reinforcement method for the pavilion-type brick masonry ancient tower provided by the present invention adopt a combination of internal reinforcement and external reinforcement to carry out overall reinforcement of the ancient tower. This double reinforcement strategy not only ensures the stability of the internal structure of the ancient tower, but also takes into account the reinforcement requirements of the external wall. The wall and floor of the ancient tower can be firmly fixed to the steel structure, achieving the coordinated reinforcement effect of the inside and outside, thereby significantly improving the structural strength of the ancient tower, providing a strong guarantee for the long-term protection and use of the ancient tower, and meeting the needs of historical and cultural heritage protection and sustainable development.
