In order to save building construction costs and avoid unnecessary building renovation, the aging building structure is usually secondarily reinforced to continue to be safely used. In order to avoid production stoppage and reduce the loss caused by production stoppage, the building structure is usually secondarily reinforced to meet new use requirements. When some old buildings in a city are renovated, the old buildings need to be reinforced to facilitate the renovation work.

The inner vertical surface of the sleeve clamping plate is provided with anti-skid lines to prevent the sleeve clamping plate from sliding downward. One end of a hose is connected to a connecting end, and the other two ends of the hose are connected to the ports of an extension rod. Finally, a steel wire rope is embedded in a clamping handle, and the steel wire rope is clamped tightly in cooperation with the use of a circular block. The device is not only convenient to disassemble, but also firm and fixed, and no punching is needed to avoid damage to the building. However, the patent still has the following problems in actual use: The beam reinforcement structure device for building structure design can sleeve four sleeve clamping plates at the top end of a beam column, and use a No. 1 bolt and a No. 3 bolt to fix the four sleeve clamping plates to each other.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: This building structure reinforcement device for urban renewal, when only wall support is needed, can be inverted, and the entire device can be fixed using the fixing bolts inside the curved support plate, further improving the support stability of the reinforcement device. It can adjust the horizontal support frame according to the size of the building space, thus adapting to buildings with limited space and facilitating renovation work within the building. By setting an adjustable support mechanism, it can support floor slabs and beam bottoms, as well as walls and columns, improving the applicability of the entire reinforcement device. It eliminates the need for additional support structures, achieving cost savings. When adjusting the height of the entire device, the bottom opening support plate and curved support legs can be unfolded, thereby increasing the bottom support area of the reinforcement device and further improving its support stability. The specific details are as follows: 1. By setting an adjustable support mechanism, the adjustable threaded sleeve and the lifting sleeve can be connected by threads to move the adjustable threaded sleeve and the limiting ring. The engaging connection between the locking block and the limiting ring secures the support rotating rod, thus keeping the horizontal support frame level. The support sliding plate at the top of the horizontal support frame reinforces the floor slab and beam sections, facilitating building renovation. Since the tilt angle of the support rotating rod is exactly the same as the tilt angle when the locking block and the outer side of the lifting sleeve are in contact, the horizontal support frame remains level, and this is further ensured by the locking screw... The bolts reinforce the horizontal support frame, thereby improving its stability. When support is needed at the connection between the floor slab and the wall, one side of the horizontal support frame can be rotated to a vertical position, and the vertically positioned horizontal support frame can be moved to the side of the wall. This reinforces the connection between the floor slab and the wall. Utilizing the sliding connection between the internal sliding rod and the sliding sleeve of the horizontal support frame, the sliding limit block and the support sliding plate can be moved. Furthermore, the locking pin and locking hole can be used to fix the sliding limit block and the support sliding plate, thus expanding the support area. This system is suitable for floor slabs or beam bottoms with long cracks. When the translation limit block and supporting sliding plate need to be retracted, pressing the unlock button together moves the second connecting plate and locking pin closer together. When the locking pin separates from the locking hole, the translation limit block and supporting sliding plate can be retracted. Under the elastic force of the top spring telescopic rod of the fixed support plate and the first buffer spring, and under the action of the buffer rotating rod, the buffer sliding sleeve slides relative to the outside of the buffer sliding rod. At the same time, the buffer sliding sleeve drives the supporting connecting rod and the supporting arc plate to unfold, which facilitates the support of the top floor slab and improves the support stability of the reinforcement device. When only wall support is needed, the entire support device can be inverted, and the fixing bolts inside the support arc plate can be used to fix the entire device, further improving the support stability of the reinforcement device. The horizontal support frame can be adjusted according to the size of the building space, thus adapting to buildings with small spaces and facilitating renovation work for workers inside the building. By setting an adjustable support mechanism, it can support the floor slab and beam bottom, as well as the wall and column, improving the applicability of the entire reinforcement device. No additional support structure is required, achieving the effect of saving costs. 2. By setting up a lifting support mechanism, the lifting handle can be used to drive the first bevel gear transmission assembly and the top lifting threaded rod to rotate, causing the lifting threaded sleeve to drive the lifting sliding plate and the lifting sleeve to move up and down. This allows the entire device to be height-adjusted to accommodate different building heights. Simultaneously, the first bevel gear transmission assembly drives the bottom lifting threaded rod and the second bevel gear transmission assembly to rotate, causing the second bevel gear transmission assembly to drive the opening and closing threaded rod to rotate. Under the action of the roller bracket and support rollers, the opening and closing threaded sleeve drives the opening and closing limit block, the opening and closing support plate, and the arc-shaped support leg to unfold. When adjusting the height of the entire device, the bottom opening and closing support plate and the arc-shaped support leg can be unfolded, thereby increasing the bottom support area of the reinforcement device and further improving the support stability of the reinforcement device.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-5 , Figure 9The present invention provides a technical solution: a building structure reinforcement device for urban renewal, comprising an adjustable support mechanism 1 and a support plate 109 installed on the top of the adjustable support mechanism 1. A lifting support mechanism 2 is provided at the bottom of the adjustable support mechanism 1, and a lifting sleeve 208 is provided on the outer side of the lifting support mechanism 2. The adjustable support mechanism 1 includes an adjusting threaded sleeve 101, an anti-slip plate 102 is fixedly installed on the outer side of the adjusting threaded sleeve 101, and a limiting ring 103 is fixedly installed on the top of the adjusting threaded sleeve 101. The top of the limiting ring 103... A locking block 104 is engaged, and a support rotating rod 105 is rotatably connected to the top of the locking block 104. A horizontal support frame 106 is rotatably connected to the top of the support rotating rod 105, and a rotating support 107 is rotatably connected to the end of the horizontal support frame 106. The rotating support 107 is fixedly installed around the support plate 109, and a locking bolt 108 is threaded into the interior of the rotating support 107. A sliding groove 110 is provided inside the horizontal support frame 106, and two translation sliding rods 111 are symmetrically installed inside the sliding groove 110. The outer sides of the moving rod 111 are slidably connected to translational sliding sleeves 112. A translational sliding block 113 is fixedly installed between the two translational sliding sleeves 112. A translational limiting block 114 is fixedly installed on the top of the translational sliding block 113. A support sliding plate 115 is fixedly installed on one side of the translational limiting block 114. Utilizing the threaded connection between the adjusting threaded sleeve 101 and the lifting sleeve 208, the lifting and lowering movement of the adjusting threaded sleeve 101 and the limiting ring 103 can be realized. Utilizing the engaging connection between the engaging block 104 and the limiting ring 103, the supporting rotating rod 111 can be realized. The fixing of 05 ensures that the horizontal support frame 106 remains horizontal. The support sliding plate 115 at the top of the horizontal support frame 106 can support and reinforce the openings of the floor slab and beam, facilitating building renovation. Since the tilt angle of the support rotating rod 105 is exactly the tilt angle when the locking block 104 and the outer side of the lifting sleeve 208 are in contact, it can ensure that the horizontal support frame 106 is in a horizontal state. The horizontal support frame 106 is reinforced by the locking bolt 108, thereby improving the support stability of the horizontal support frame 106.
[0020] Please see Figures 3-8The bottom of the sliding block 113 is symmetrically equipped with unlocking brackets 116. Unlocking sliding rods 117 are symmetrically installed inside each of the two unlocking brackets 116. Unlocking sliding sleeves 118 are slidably connected to the outer sides of each of the four unlocking sliding rods 117. A first connecting plate 119 is fixedly installed between the two unlocking sliding sleeves 118. A locking spring 120 is fixedly installed on one side of each unlocking sliding sleeve 118. A locking pin 121 is fixedly installed at the bottom of each unlocking sliding sleeve 118. A second connecting plate 122 is fixedly installed between the two locking pins 121. Unlocking buttons 123 are fixedly installed at the bottom of each of the two second connecting plates 122. Several locking holes 124 are provided on both sides of the bottom of the horizontal support frame 106 near the moving slide 110. The insertion hole 124 engages with the locking pin 121. A fixed support plate 125 is fixedly installed on the top of the support plate 109. A spring telescopic rod 126 is fixedly installed at the center of the top of the fixed support plate 125. A first buffer spring 127 is fixedly installed on the outer side of the fixed support plate 125 near the spring telescopic rod 126. A buffer sliding plate 128 is fixedly installed on the top of the spring telescopic rod 126 and the first buffer spring 127. A buffer rotating rod 129 is rotatably connected around the top of the fixed support plate 125. A buffer sliding sleeve 130 is rotatably connected to the top of the buffer rotating rod 129. A buffer sliding rod 131 is slidably connected inside the buffer sliding sleeve 130. The buffer sliding rod 131 is fixedly installed inside the buffer sliding plate 128. A second buffer spring 132 is fixedly installed on one side of the sliding sleeve 130, and a support connecting rod 133 is fixedly installed on the top of the buffer sliding sleeve 130. A support arc plate 134 is fixedly installed at the end of the support connecting rod 133. When it is necessary to support the connection between the floor slab and the wall, the horizontal support frame 106 on one side can be rotated to a vertical state and the vertical horizontal support frame 106 can be moved to one side of the wall to reinforce the connection between the floor slab and the wall. By utilizing the feature that the translation sliding rod 111 inside the horizontal support frame 106 is slidably connected to the translation sliding sleeve 112, the movement of the translation limit block 114 and the support sliding plate 115 can be realized, and the locking pin 121 is engaged with the locking hole 124. The connection features allow for the fixation of the translation limit block 114 and the support sliding plate 115, thereby expanding the support position. This is suitable for floor slabs or beam bottoms with long cracks. When it is necessary to retract the translation limit block 114 and the support sliding plate 115, pressing the unlocking button 123 together will move the second connecting plate 122 and the locking pin 121 closer together. When the locking pin 121 separates from the locking hole 124, the translation limit block 114 and the support sliding plate 115 can be retracted. Under the elastic force of the spring telescopic rod 126 at the top of the fixed support plate 125 and the first buffer spring 127, and under the action of the buffer rotating rod 129, the buffer sliding sleeve 130 slides relative to the outside of the buffer sliding rod 131.Simultaneously, the buffer sliding sleeve 130 drives the support connecting rod 133 and the support arc plate 134 to unfold, facilitating support for the top floor slab and improving the support stability of the reinforcement device.
[0021] Please see Figures 1-8 The internal threaded connection of the supporting arc plate 134 is a fixing bolt 135. When only the wall needs to be supported, the entire support device can be inverted, and the fixing bolt 135 inside the supporting arc plate 134 can be used to fix the entire device, further improving the support stability of the reinforcement device. The horizontal support frame 106 can be adjusted according to the size of the building space, so as to adapt to buildings with small spaces and facilitate workers to carry out renovation work in the building. By setting the adjustable support mechanism 1, it can support the floor slab and the bottom of the beam, as well as the wall and column, improving the applicability of the entire reinforcement device. No additional support structure is required, which achieves the effect of saving costs.
[0022] Please see Figure 1 , Figures 8-11The lifting support mechanism 2 includes a lifting bracket 201. A support column 202 is fixedly installed at the bottom of the lifting bracket 201. A lifting rotating handle 203 is rotatably connected to the outer side of the bottom of the lifting bracket 201. A first bevel gear transmission assembly 204 is fixedly installed at the end of the lifting rotating handle 203. A top lifting threaded rod 205 is fixedly connected to the top of the first bevel gear transmission assembly 204. A lifting threaded sleeve 206 is threadedly connected to the outer side of the top lifting threaded rod 205. A lifting sliding plate 207 is fixedly installed on the outer side of the lifting threaded sleeve 206. A lifting sleeve 208 is fixedly installed on the lifting sliding plate 207. At the top of 7, the lifting sleeve 208 is fixedly installed at the bottom of the support plate 109, the support base 209 is fixedly installed at the bottom of the support column 202, the bottom lifting threaded rod 210 is fixedly installed at the bottom of the first bevel gear transmission assembly 204, the bottom lifting threaded rod 210 is fixedly installed at the bottom of the bottom lifting threaded rod 210, the opening and closing threaded rod 212 is fixedly installed around the second bevel gear transmission assembly 211, the outer side of the opening and closing threaded rod 212 is threadedly connected to the opening and closing threaded sleeve 213, the bottom of the opening and closing threaded sleeve 213 is fixedly installed with an opening and closing limit block 214, and the opening and closing limit block 214... A hinged support plate 215 is fixedly installed at the bottom, and an arc-shaped support leg 216 is fixedly installed at the end of the hinged support plate 215. Roller brackets 217 are symmetrically installed around the bottom of the support base 209. Support rollers 218 are rotatably connected inside the two roller brackets 217. The lifting handle 203 drives the first bevel gear transmission assembly 204 and the top lifting threaded rod 205 to rotate, causing the lifting threaded sleeve 206 to drive the lifting sliding plate 207 and the lifting sleeve 208 to move up and down. This allows the entire device to be height-adjusted, adapting to different building heights. Simultaneously, the first… The bevel gear transmission assembly 204 drives the bottom lifting threaded rod 210 and the second bevel gear transmission assembly 211 to rotate, which in turn drives the opening and closing threaded rod 212 to rotate. At the same time, under the action of the roller bracket 217 and the support roller 218, the opening and closing threaded sleeve 213 drives the opening and closing limit block 214, the opening and closing support plate 215 and the arc-shaped support leg 216 to unfold. When adjusting the height of the entire device, the bottom opening and closing support plate 215 and the arc-shaped support leg 216 can be unfolded, thereby increasing the bottom support area of the reinforcement device and further improving the support stability of the reinforcement device.
[0023] Working principle: Before using this type of building structure reinforcement device for urban renewal, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 11As shown, firstly, the lifting and rotating handle 203 drives the first bevel gear transmission assembly 204 and the top lifting threaded rod 205 to rotate, causing the lifting threaded sleeve 206 to drive the lifting sliding plate 207 and the lifting sleeve 208 to move up and down, thereby enabling the height adjustment of the entire device to adapt to different building floors. At the same time, the first bevel gear transmission assembly 204 drives the bottom lifting threaded rod 210 and the second bevel gear transmission assembly 211 to rotate, causing the second bevel gear transmission assembly 211 to drive the opening and closing threaded rod 212 to rotate. Simultaneously, under the action of the roller bracket 217 and the supporting roller 218, the opening and closing threaded sleeve 213 drives the opening and closing limit block 214, the opening and closing support plate 215 and the arc-shaped support leg 216 to unfold. When adjusting the height of the entire device, the bottom opening and closing support plate 215 and the arc-shaped support leg 216 can be unfolded, thereby increasing the bottom support area of the reinforcement device and further improving the support stability of the reinforcement device.
[0024] Secondly, by utilizing the threaded connection between the adjusting threaded sleeve 101 and the lifting sleeve 208, the adjusting threaded sleeve 101 and the limiting ring 103 can be moved up and down. By utilizing the engaging connection between the locking block 104 and the limiting ring 103, the supporting rotating rod 105 can be fixed, thereby keeping the horizontal support frame 106 in a horizontal state. The supporting sliding plate 115 at the top of the horizontal support frame 106 can support and reinforce the openings of the floor slab and beam, facilitating building renovation. Since the tilt angle of the supporting rotating rod 105 is exactly the tilt angle when the locking block 104 and the outer side of the lifting sleeve 208 are in contact, the horizontal support frame 106 can be kept in a horizontal state. The horizontal support frame 106 is reinforced by the locking bolt 108, thereby improving the support stability of the horizontal support frame 106.
[0025] Finally, when support is needed at the connection between the floor slab and the wall, the horizontal support frame 106 on one side can be rotated to a vertical position, and then the vertically positioned horizontal support frame 106 can be moved to one side of the wall. This reinforces the connection between the floor slab and the wall. Utilizing the sliding connection between the internal sliding rod 111 and the sliding sleeve 112 of the horizontal support frame 106, the movement of the sliding limit block 114 and the supporting sliding plate 115 can be achieved, and the locking pin 121 and the locking hole 124 can be used to lock them in place. The combined connection allows for the fixation of the translation limit block 114 and the support sliding plate 115, thereby expanding the support position. This is suitable for floor slabs or beam bottoms with long cracks. When the translation limit block 114 and the support sliding plate 115 need to be retracted, pressing the unlocking button 123 together moves the second connecting plate 122 and the locking pin 121 closer together. When the locking pin 121 separates from the locking hole 124, the translation limit block 114 and the support sliding plate 115 can be retracted, utilizing the fixed support... Under the elastic force of the top spring telescopic rod 126 and the first buffer spring 127 of the support plate 125, and under the action of the buffer rotating rod 129, the buffer sliding sleeve 130 slides relative to the outside of the buffer sliding rod 131. At the same time, the buffer sliding sleeve 130 drives the support connecting rod 133 and the support arc plate 134 to unfold, which facilitates the support of the top floor slab and improves the support stability of the reinforcement device. When only the wall needs to be supported, the entire support device can be inverted, and the fixing bolts 135 inside the support arc plate 134 can be used to fix the entire device, further improving the support stability of the reinforcement device. The horizontal support frame 106 can be adjusted according to the size of the building space, so as to adapt to the building with a small space and facilitate workers to carry out renovation work in the building. By setting the adjustable support mechanism 1, it can support the floor slab and the bottom of the beam, and at the same time support the wall and column, improving the applicability of the entire reinforcement device. No additional support structure is required, which achieves the effect of saving costs.
