Description

Technical Field:

[0001] The utility model relates to the field of building deformation joints, and specifically relates to a building deformation joint protection structure. Background Art:

[0002] Building deformation joints are divided into three types according to different external damage factors, namely expansion joints, settlement joints and seismic joints. In industrial and civil buildings, due to the influence of factors such as temperature changes, uneven settlement of the foundation, and earthquakes, additional stresses and deformations will be generated inside the building structure. If not properly handled, it will cause damage to the building, cracks or even collapse, affecting use and safety.

[0003] The utility model patent with the application number 202122094864.2 discloses a building deformation joint protection structure, which reduces the possibility of rust on the surface of the protection structure body by applying an anti-corrosion layer on the surface of the protection structure body. However, it cannot adjust the width of the building deformation joint, which will affect the construction efficiency of the deformation joint.

[0004] At the same time, the existing protection device cannot fix the structure, resulting in the structure shifting during use, which reduces the construction efficiency of the deformation joint. Summary of the Invention:

[0005] The technical problem to be solved by the utility model is to provide a building deformation joint protection structure that can adjust the width of the building deformation joint and has a stable structure.

[0006] The purpose of the utility model is realized as follows: It includes a support frame, and the support frame includes two vertical plates arranged left and right and a top plate fixed to the tops of the two vertical plates;

[0007] A horizontal sliding groove is provided on the lower surface of the top plate of the support frame. The left and right two limit sliders are slidably installed in the sliding groove. The bottoms of the two limit sliders are respectively fixedly connected with adjusting plates. Among them, a left threaded rod extending to the left is movably connected to the adjusting plate on the left side. The left threaded rod is threadedly connected to the left vertical plate of the support frame and its left end extends out of the vertical plate. A handle is fixed to the left end of the left threaded rod; a right threaded rod extending to the right is movably connected to the adjusting plate on the right side. The right threaded rod is threadedly connected to the right vertical plate of the support frame and its right end extends out of the vertical plate. A handle is also fixed to the right end of the right threaded rod; rotating the handle drives the threaded rod to rotate, and then drives the adjusting plate to move.

[0008] Both the left threaded rod and the right threaded rod are connected to the adjusting plate through bearings.

[0009] Through holes are correspondingly provided on both of the two adjusting plates. The left and right ends of the injection pipe are respectively fixed on the two vertical plates of the support frame. The injection pipe located inside the support frame passes through the through holes of the two adjusting plates. A slurry outlet hole is provided at the middle position of the injection pipe. A cushion block is fixed on the injection pipe outside the two vertical plates of the support frame. The cushion block contacts the vertical plate of the support frame. The diameter of the through hole is larger than the diameter of the injection pipe.

[0010] Inlet ports are provided on the injection pipes outside the two vertical plates. A rotating shaft is provided inside the injection pipe. A screw conveyor blade is nested and connected outside the rotating shaft. The left and right ends of the rotating shaft both extend out of the injection pipe, and gears are fixed on the extending parts. When a deformation joint needs to be grouted, concrete is injected through the inlet port. The external motor gear meshes with the gear at the end of the rotating shaft to drive the rotating shaft to rotate. Then the rotating shaft drives the screw conveyor blade to rotate, pushing the cement slurry into the injection pipe, and injecting the concrete into the deformation joint through the slurry outlet hole of the injection pipe.

[0011] Fixing plates extending outward are provided at the lower ends of the two vertical plates of the support frame. A number of mounting holes are provided on both fixing plates. A fixing column is provided in each mounting hole, and a bolt is connected to the top of each fixing column. A number of positioning blocks are embedded on the lower surfaces of the two fixing plates. The positioning blocks have shapes and sizes matching the positioning parts on the ground or the foundation structure, so that when the device is placed at the position of the positioning part on the ground or the foundation structure, the positioning blocks can be docked with the corresponding parts on the ground or the foundation structure.

[0012] The advantages of the present utility model are:

[0013] When a deformation joint needs to be grouted, concrete is injected through the inlet port. The external motor gear meshes with the gear of the rotating shaft to drive the rotating shaft to rotate. Then the rotating shaft drives the auger to rotate, pushing the cement slurry to the bottom of the injection pipe, and injecting the concrete into the deformation joint through the slurry outlet hole at the bottom of the injection pipe. When the rotating shaft is rotating, it pressurizes the cement slurry in the injection pipe and can also stir the concrete evenly during this process.

[0014] When it is necessary to change the width of the deformation joint, the staff rotates the handle to drive the threaded rod to rotate inside the support frame. Supported by the support frame, when the threaded rod drives the adjusting plate to move left or backward, the limiting block on the top of the adjusting plate moves in the chute to play a role in limiting the adjusting plate. This device can adjust the width of the deformation joint, improving the flexibility of the device and thus improving the work efficiency. Description of the drawings:

[0018] Figure 4 It is Figure 1 an enlarged structure diagram of part A in Specific implementation manner:

[0019] The following combines Figures 1-4 to further illustrate the present utility model;

[0020] It includes a support frame 1, and the support frame includes two vertical plates arranged left and right and a top plate fixed to the tops of the two vertical plates;

[0021] A horizontal chute 2 is provided on the lower surface of the top plate of the support frame. The left and right two limit sliders 3 are slidably installed in the chute. The bottoms of the two limit sliders are respectively fixedly connected with adjusting plates 4. Among them, a left threaded rod 5 extending to the left is movably connected to the adjusting plate on the left side. The left threaded rod is threadedly connected to the left vertical plate of the support frame and its left end extends out of the vertical plate. A handle 6 is fixed to the left end of the left threaded rod; A right threaded rod 7 extending to the right is movably connected to the adjusting plate on the right side. The right threaded rod is threadedly connected to the right vertical plate of the support frame and its right end extends out of the vertical plate. A handle is also fixed to the right end of the right threaded rod. Rotating the handle drives the threaded rod to rotate, and then drives the adjusting plate to move.

[0022] Both the left threaded rod and the right threaded rod are connected to the adjusting plate through bearings.

[0023] Through holes are correspondingly provided on both adjusting plates. The left and right ends of the injection pipe 8 are respectively fixed to the two vertical plates of the support frame. The injection pipe located inside the support frame passes through the through holes of the two adjusting plates. A slurry outlet hole is provided at the middle position of the injection pipe. A cushion block 9 is fixed on the injection pipe outside the two vertical plates of the support frame. The cushion block contacts the vertical plate of the support frame. The diameter of the through hole is larger than the diameter of the injection pipe.

[0024] On the injection pipes located outside the two vertical plates, there are injection ports 10. Inside the injection pipes, there are rotating shafts 11. Outside the rotating shafts, there are nested auger blades 12. The left and right ends of the rotating shafts both extend out of the injection pipes, and gears 13 are fixed on the extended parts. When a deformation joint needs to be grouted, concrete is injected through the injection ports. The external motor gear meshes with the gear at the end of the rotating shaft to drive the rotating shaft to rotate. Then the rotating shaft drives the auger blades to rotate, pushing the cement slurry into the injection pipe and injecting the concrete into the deformation joint through the slurry outlet holes of the injection pipe. When the rotating shaft is rotating, the auger blades rotate to pressurize the cement slurry in the injection pipe and can also stir the concrete evenly during this process, improving the accuracy of concrete grouting and the grouting efficiency.

[0025] At the lower ends of the two vertical plates of the support frame, there are fixed plates 14 extending outward. On the two fixed plates, there are several mounting holes. Inside each mounting hole, there is a fixed column 15, and at the top of each fixed column, there is a bolt 16 connected. On the lower surfaces of the two fixed plates, several positioning blocks 17 are embedded. The positioning blocks have shapes and sizes matching the positioning parts on the ground or the foundation structure. When the device is placed at the position of the positioning part on the ground or the foundation structure, the positioning blocks can be docked with the corresponding parts on the ground or the foundation structure, thus ensuring the positioning accuracy and positioning stability of the entire protective structure. After positioning, the bolts can be driven in for fixation. The fixed columns at the bottom of the bolts are driven into the ground to fix the device. By setting the fixed plates, the stability of the device is improved, and thus the working efficiency is also improved.

[0026] Working process: Place the device at the designated position, position it through the positioning blocks at the bottom and the positioning parts on the ground or the foundation structure. After positioning, the bolts can be driven in for fixation. The fixed columns at the bottom of the bolts are driven into the ground to fix the device. After fixation, when it is necessary to change the width of the deformation joint, the staff rotates the handle to drive the threaded rod to rotate inside the support frame. Supported by the support frame, when the threaded rod drives the adjusting plate to move left or right, the limit sliding block at the top of the adjusting plate moves in the chute, playing a role in limiting the adjusting plate. Inject the concrete through the injection port of the injection pipe. The external motor gear meshes with the gear of the rotating shaft to drive the rotating shaft to rotate. Then the rotating shaft drives the auger blades to rotate, pushing the cement slurry to the bottom of the injection pipe and injecting the concrete into the deformation joint through the slurry outlet holes at the bottom of the injection pipe. When the rotating shaft is rotating, the auger blades can pressurize the cement slurry in the injection pipe and stir the concrete evenly during this process.
