Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a prefabricated sleeve grouting device for buildings. Background Technology

[0002] Buildings constructed from precast components have seen steady development thanks to public attention and government support. The construction process for prefabricated buildings typically involves casting individual components in a factory, transporting them to the site, and then assembling them, enabling rapid construction. In prefabricated reinforced concrete structure engineering, grouting sleeve connection is a common and universal connection method. Two precast components to be connected have pre-embedded, corresponding connecting reinforcing bars on their facing surfaces. These connecting reinforcing bars are inserted into the sleeve from both ends, and high-strength concrete grout is poured into the sleeve. After solidification, a stable connection is achieved.

[0003] When using existing grouting sleeves for grouting, after grouting is completed inside the sleeve, the outlet of the grout pipe is usually sealed with a rubber or wooden plug. Then, the grout pipe is pulled out of the grouting port and the rubber or wooden plug is inserted into the grouting port to seal it again. In this method of sealing the grouting hole, the time interval between removing the rubber or wooden plug after pulling out the grout pipe should not exceed one second. Otherwise, the grout may flow backward, which not only increases the difficulty of the workers' work, but also easily causes air bubbles and pores inside the grout pipe, affecting the overall quality.

[0008] Preferably, a first spring is sleeved on the outside of the first insertion rod, one end of the first spring is fixedly connected to the first connecting piece, and the other end of the first spring is fixedly connected to the support frame.

[0009] Preferably, a second spring is sleeved on the outside of the second insertion rod, one end of the second spring is fixedly connected to the second connecting piece, and the other end of the second spring is fixedly connected to the fluoroscopic tube.

[0010] Preferably, the first insertion rod has a first magnetic sheet at one end inside the support frame, and a second magnetic sheet that attracts each other on the first magnetic sheet. The second magnetic sheet is disposed on the sealing block, and the outer wall specifications of the first magnetic sheet and the second magnetic sheet are larger than the end specifications of the first insertion rod.

[0011] Preferably, the grouting sleeve has fixed rings on both sides inside, and a linkage component is provided inside the fixed ring. The linkage component includes a connecting frame, which is slidably inserted into the fixed ring. Linkage springs are provided on both sides of the top of the connecting frame. One end of the linkage spring is fixedly connected to the connecting frame, and the other end of the linkage spring is fixedly connected to the fixed ring. The bottom of the connecting frame has several ring-shaped and fixedly connected top blocks. The top of each top block has a fixedly connected extrusion plate, and the top of the extrusion plate is an inclined slope.

[0012] Preferably, the fixing ring has a sealing rubber cylinder at its center near the end of the grouting sleeve, and a plurality of ring-shaped and fixedly connected support frames are provided on one side of the fixing ring near the end of the grouting sleeve. A slidingly connected guide rod is inserted inside the support frame, and a fixedly connected extrusion block is provided at the end of the guide rod. A third spring is sleeved on the outside of the guide rod, and the two ends of the third spring are fixedly connected to the support frame and the extrusion block, respectively. The side wall of the extrusion block near the sealing rubber cylinder is an arc surface, and the outer wall of the extrusion block is an inclined slope surface. The position of the extrusion block corresponds to the position of the extrusion sheet.

[0013] Preferably, a first piezoelectric ceramic is provided at the end of the feed pipe away from the discharge pipe, a second piezoelectric ceramic is provided on the slider, a driver connected to the first piezoelectric ceramic is provided outside the feed pipe, and an oscilloscope connected to the second piezoelectric ceramic is provided outside the fluoroscopic tube.

[0014] Preferably, both ends of the grouting sleeve are provided with fixedly connected guide rings, the inside of the guide rings is a conical groove, the inside of the grout discharge pipe is provided with a fixedly connected retaining ring, the end of the grout discharge pipe is provided with a fixedly connected adapter pipe, and the outer wall of the adapter pipe is threadedly connected to the inner wall of the discharge pipe.

[0015] Compared with related technologies, the prefabricated sleeve grouting device for buildings provided by the present invention has the following beneficial effects: This invention, through the setting of the feeding component, requires that after the grouting injection is completed, the grouting roller needs to be pulled out and then sealed with a sealing plug. After the grouting is completed, the sealing plate can be controlled to move into the installation frame for sealing. This sealing method can avoid the time difference between removing the grouting pipe for sealing, which would cause the grout to flow back and cause air bubbles and holes in the grouting sleeve, thus improving the grouting effect of this device in the later stage.

[0016] This invention, through the setting of the discharge component, allows workers to observe the position of the grout through a viewing tube during the grouting process. When the grout pushes the first sliding plate and drives the second insert rod to slide, tools such as hammers can be used to hammer the first connecting piece at the end of the first insert rod, causing it to move the sealing plug at the end into the discharge pipe until the sealing plug moves into the transfer pipe and abuts against the end of the retaining ring, thus completing the sealing of the grout discharge pipe. Workers do not need to additionally take the sealing plug for alignment and insertion, making the entire sealing process more convenient and faster.

[0017] This invention, through the setting of the linkage component, allows the extrusion plate in the connecting frame to move smoothly when the end of the rebar abuts against the inner top of the connecting frame during the insertion of the rebar into the grouting sleeve. This extrusion plate then presses against the extrusion block, which in turn presses against the outer wall of the sealing rubber cylinder. The deformed sealing rubber cylinder then abuts against the outer wall of the rebar, thus sealing the rebar and the grouting sleeve without the need for additional tape binding. The entire sealing process is more convenient.

[0018] This invention, by setting guide rings at both ends of the grouting sleeve, guides the ends of the reinforcing bars during insertion, making the insertion of the reinforcing bars into the grouting sleeve smoother and more convenient. Therefore, it can help improve the efficiency of workers in the later stages of construction. This invention utilizes a first and a second piezoelectric ceramic, connecting each ceramic to a driver and an oscilloscope. During the grouting process, the driver causes the corresponding piezoelectric ceramic to generate a signal wave, which is displayed on the oscilloscope. Workers can then use the oscilloscope display to inject concrete grout into the sleeve. The grout, containing air bubbles, flows out from the outlet pipe, resulting in a denser filling of the sleeve with concrete grout. This process continues until the required saturation of the concrete grout between the two piezoelectric ceramics is achieved, thus improving the grouting effect of the device in the later stages.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 9 The present invention provides a prefabricated building sleeve grouting device, which includes a grouting sleeve 1, and a grouting pipe 13 and a grouting pipe 14 connected to each other on both sides inside the grouting sleeve 1.

[0024] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The end of the grouting pipe 13 is provided with a feeding assembly 2. The feeding assembly 2 includes a connecting sleeve 21. The connecting sleeve 21 is threaded onto the end of the grouting pipe 13. The end of the connecting sleeve 21 is provided with a connected mounting frame 211. The end of the mounting frame 211 away from the connecting sleeve 21 is provided with a connected feeding pipe 212. The top of the mounting frame 211 is provided with a sealing cover 22. A threaded rotating rod 221 is inserted inside the sealing cover 22. The top of the rotating rod 221 is provided with a fixedly connected turntable 222. The bottom of the rotating rod 221 is provided with a fixedly connected sealing piece 223. The outer wall of the sealing piece 223 abuts against and slides against the inner wall of the mounting frame 211. The outer wall of the sealing piece 223 is covered with a rubber cover.

[0025] It should be noted that after the grouting injection is completed, the grouting roller needs to be pulled out and then sealed with a sealing plug. After the grouting is completed, the sealing plate 223 can be moved into the installation frame 211 for sealing. This sealing method can avoid the time difference between taking the grouting pipe off for sealing 32, which would cause the grout to flow back and cause air bubbles to appear in the grouting sleeve 1, thereby improving the grouting effect of this device in the later stage. By setting a rubber cover on the outside of the sealing piece 223, the rubber cover can increase the fit between the sealing piece 223 and the mounting frame 211, thereby helping to increase the sealing effect of the sealing piece 223 on the mounting frame 211 in the later stage; Since the connecting sleeve 21 is connected to the outside of the grouting pipe 13 through the internal threaded connecting groove, and the inner wall specifications of the connecting sleeve 21 are the same as those of the inner wall of the grouting pipe after connection, the connecting sleeve 21 can be directly controlled to rotate after the concrete grout solidifies, and the feeding component 2 can be disassembled.

[0026] In an embodiment of the present invention, please refer to Figure 1 and Figure 5The end of the discharge pipe 14 is provided with a discharge assembly 3, which includes a discharge pipe 31. The discharge pipe 31 is sleeved outside the discharge pipe, and a support frame 311 is sleeved outside the discharge pipe 31. A slidingly connected first insert rod 312 is inserted into the side of the support frame 311 away from the discharge pipe 31. The end of the first insert rod 312 outside the support frame 311 is provided with a fixedly connected first connecting piece 314. The end of the first insert rod 312 inside the support frame 311 is provided with a movably connected sealing plug 32, and the sealing plug 32 is movably inserted into the discharge pipe 31. The discharge pipe 31 is provided with a communicating viewing tube 33, and a sliding connecting piece is inserted into the viewing tube 33. The second insertion rod 332 is connected to the first insertion rod 312. The first insertion rod 312 is fitted with a first spring 313. One end of the first spring 313 is fixedly connected to the first connecting piece 314, and the other end of the first spring 313 is fixedly connected to the support frame 311. The second insertion rod 332 is fitted with a second spring 333. One end of the second spring 333 is fixedly connected to the second connecting piece 334, and the other end of the second spring 333 is fixedly connected to the fluoroscopic tube 33.

[0027] It should be noted that during the grouting process, the staff can observe the position of the grout through the viewing tube 33. When the grout pushes the sliding plate 331 and drives the second insert rod 332 to slide upward, tools such as hammers can be used to hammer the first connecting piece 314 at the end of the first insert rod 312, causing it to move the sealing plug 32 at the end towards the inside of the discharge pipe 31 until the sealing plug 32 moves into the inside of the transfer pipe 142 and abuts against the end of the retaining ring 141, thus completing the sealing of the grout discharge pipe 14. The staff does not need to take the sealing plug 32 for alignment and sealing, making the entire sealing process more convenient and faster. Meanwhile, the first spring 313 can smoothly compress the sealing plug 32 through its own driving force, thereby making the sealing plug 32 stably located inside the transfer pipe 142. The second spring 333 can drive the sliding plate 331 towards the perspective tube 33 during grouting. This will prevent the sliding plate 331 from sliding outward due to the outward flow of gas during concrete pouring.

[0028] In an embodiment of the present invention, please refer to Figure 5 The first insertion rod 312 is provided with a first magnetic sheet 315 at one end inside the support frame 311. The first magnetic sheet 315 is provided with a second magnetic sheet 321 that attracts each other. The second magnetic sheet 321 is provided on the sealing block 32, and the outer wall specifications of the first magnetic sheet 315 and the second magnetic sheet 321 are larger than the end specifications of the first insertion rod 312.

[0029] It should be noted that the inner wall of the discharge pipe 31 is connected to the outer wall of the adapter pipe 142 through a threaded groove, and the inner wall of the discharge pipe 31 after connection has the same specifications as the inner wall of the adapter pipe 142. At the same time, the first insert rod 312 is connected to the sealing plug 32 by using the first magnetic piece 315 and the second magnetic piece 321. After the concrete grouting is completed, when the internal concrete solidifies, the discharge pipe 31 can be rotated to smoothly unscrew the discharge pipe 31 from the outside of the adapter pipe 142. During this process, the first magnetic piece 315 and the second magnetic piece 321 can be easily separated from each other, which makes the disassembly of the discharge assembly 3 more convenient in the later stage. Meanwhile, a first magnetic plate 315 and a second magnetic plate 321 with relatively large specifications are set. During the pouring of concrete slurry, when the sealing plug 32 located inside the discharge pipe 31 is squeezed by the concrete slurry, the first magnetic plate 315 and the second magnetic plate 321 with relatively large specifications can smoothly abut against the inside of the support frame 311, thereby preventing the sealing plug 32 from falling off from the inside of the discharge pipe 31. Therefore, it is convenient for personnel to hammer the sealing plug 32 to seal it later.

[0030] In an embodiment of the present invention, please refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 The grouting sleeve 1 has fixed rings 12 fixedly connected on both sides inside. A linkage assembly 4 is provided inside the fixed ring 12. The linkage assembly 4 includes a connecting frame 41, which is slidably inserted into the fixed ring 12. Linkage springs 411 are provided on both sides of the top of the connecting frame 41. One end of the linkage spring 411 is fixedly connected to the connecting frame 41, and the other end is fixedly connected to the fixed ring 12. Several annularly distributed and fixedly connected top blocks 42 are provided at the bottom of the connecting frame. Each top block 42 has a fixedly connected extrusion plate 421 at its top, and the top of the extrusion plate 421 is an inclined slope. The fixed rings... A sealing rubber cylinder 6 is provided at the center of the end of the grouting sleeve 12. Several ring-shaped and fixedly connected support frames 5 are provided on one side of the fixing ring 12 near the end of the grouting sleeve 1. A slidingly connected guide rod 51 is inserted inside the support frame 5. A pressing block 52 is fixedly connected at the end of the guide rod 51. A third spring 53 is sleeved on the outside of the guide rod 51. The two ends of the third spring 53 are fixedly connected to the support frame 5 and the pressing block 52 respectively. The side wall of the pressing block 52 near the sealing rubber cylinder 6 is an arc surface, and the outer wall of the pressing block 52 is an inclined slope surface. The position of the pressing block 52 corresponds to the position of the pressing piece 421.

[0031] It should be noted that by setting the outer walls of the extrusion block 52 and the extrusion plate 421 as inclined slopes, during later use, when the end of the reinforcing bar inserted into the grouting sleeve 1 abuts against the inner top of the connecting frame 41, the connecting frame 41 can be smoothly driven to slide inside the fixing ring 12. At this time, the sliding connecting frame 41 can smoothly drive the extrusion plate 421 to extrude. When the extrusion plate 421 abuts against the extrusion block 52, the inclined slope can smoothly convert the vertical driving force into the horizontal driving force, thereby enabling... The extrusion block 52 moves smoothly toward the sealing rubber cylinder 6 until it abuts against the outer wall of the sealing rubber cylinder 6, causing the sealing rubber cylinder 6 to deform. This allows the inner wall of the sealing rubber cylinder 6 to fit more fully with the outer wall of the reinforcing bar, thus quickly sealing the reinforcing bar after its insertion. With the linkage component 4 in place, there is no need for workers to wrap tape around the outside of the reinforcing bar for sealing during subsequent use of this device. This reduces the difficulty of sealing the reinforcing bar for workers and improves the user experience of this device.

[0032] In an embodiment of the present invention, please refer to Figure 1 , Figure 3 and Figure 5 The feed pipe 212 is provided with a first piezoelectric ceramic 213 at one end away from the discharge pipe 14, and a second piezoelectric ceramic 34 is provided on the slider 331. The feed pipe 212 is provided with a driver connected to the first piezoelectric ceramic 213, and the oscilloscope is provided on the outside of the oscilloscope tube 33 connected to the second piezoelectric ceramic 34.

[0033] It should be noted that by setting a driver and an oscilloscope connected to the first piezoelectric ceramic 213 and the second piezoelectric ceramic 34, during later use, when the piezoelectric ceramic is subjected to the extrusion pressure of concrete grout, the corresponding first piezoelectric ceramic 213 can generate an electromagnetic signal wave. At this time, the second piezoelectric ceramic 34 can successfully receive the signal wave and then display it on the oscilloscope. During this process, the staff can judge the air bubble status inside the grouting sleeve 1 by comparing the waveform on the oscilloscope with the standard waveform in the full state, and then control the grouting work of the grouting pipe.

[0034] In an embodiment of the present invention, please refer to Figure 1 and Figure 9 Both ends of the grouting sleeve 1 are provided with fixedly connected guide rings 11. The inside of the guide ring 11 is a conical groove. The inside of the grout discharge pipe 14 is provided with a fixedly connected retaining ring 141. The end of the grout discharge pipe 14 is provided with a fixedly connected adapter pipe 142, and the outer wall of the adapter pipe 142 is threadedly connected to the inner wall of the discharge pipe 31.

[0035] It should be noted that by setting a guide ring 11 with a tapered groove at the end of the grouting sleeve 1, when assembling the device later, after inserting the end of the reinforcing bar into the inner wall of the guide ring 11, the inclined inner wall of the guide ring 11 can smoothly guide the end of the reinforcing bar, thereby allowing the reinforcing bar to move smoothly into the interior of the grouting sleeve 1, making it more convenient to insert the steel coil later.

[0036] The working principle of the prefabricated sleeve grouting device for buildings provided by this invention is as follows: In use, the connecting steel bars required for assembly and connection can be inserted into the grouting sleeve 1 through the guide tube at the end of the grouting sleeve 1. During this process, when the end of the steel bar that has entered the grouting sleeve 1 abuts against the inner top of the connecting frame 41 in the linkage assembly 4, the connecting frame 41 can be smoothly driven to slide inside the fixing ring 12. At this time, the sliding connecting frame 41 can move smoothly through the top block 42 and the extrusion plate 421 located at its bottom. When the moving extrusion plate 421 abuts against the corresponding extrusion block 52, since the outer wall of the extrusion plate 421 and the outer wall of the extrusion block 52 are compatible cross sections, the vertically moving extrusion plate 421 can make the extrusion block 52 slide smoothly on the outer wall of the guide rod 51. When the outer wall of the sliding extrusion block 52 abuts against the outer wall of the sealing rubber cylinder 6, and the sealing rubber cylinder 6 is squeezed, the sealing rubber cylinder 6, which is deformed by the extrusion force, can smoothly abut against the outer wall of the steel bar inserted into the grouting sleeve 1, and thus can automatically seal the connection between the steel bar and the grouting sleeve 1 without the need for additional work to tie and seal the outer wall of the steel bar with tape. After the steel bars are inserted into the grouting sleeve 1 to complete the flat installation of the component, the end of the grouting pipe can be smoothly inserted into the feed pipe 212, and then the grouting work can be carried out. At this time, the concrete slurry flowing out from the grouting pipe can smoothly flow through the feed pipe 212 into the grouting pipe 13 until the concrete slurry flows into the grouting sleeve 1, fills the inside of the grouting sleeve 1, and smoothly flows from the grout discharge pipe 14 connected to the inside of the grouting sleeve 1. The concrete slurry that enters the grouting pipe flows smoothly through the transfer pipe 142 into the inside of the viewing tube 33, and squeezes the sliding plate 331 inside the viewing tube 33, causing it to drive the second insertion rod 332 to slide smoothly away from the viewing tube 33. This allows the staff to easily check the grouting status of the concrete slurry. During this process, by setting the first piezoelectric ceramic 213 and the second piezoelectric ceramic 34 inside the feed pipe 212 and the viewing tube 33 respectively, when subjected to the squeezing force of the concrete slurry, the driver connected to the first piezoelectric ceramic 213 can be turned on, causing the corresponding first piezoelectric ceramic 213 to generate an electromagnetic signal wave. At this time, the second piezoelectric ceramic 34 can successfully receive the signal wave and then display it on the oscilloscope. During this process, the staff can judge the air bubble status inside the grouting sleeve 1 by comparing the waveform on the oscilloscope with the standard waveform in the full state, and then control the grouting work of the grouting pipe. When the grouting sleeve 1 is completely filled with concrete grout, and the grout discharge pipe 14 needs to be sealed, the workers can directly pick up hammers or other hammering tools and hammer the outer wall of the first connecting piece 314. At this time, the first connecting piece 314 is driven by the hammering force to push the first insert rod 312 to squeeze the end sealing plug 32 until the plug is inserted into the adapter pipe 142 and abuts against the retaining ring 141 inside the grout discharge pipe 14, thus successfully sealing the grout discharge pipe 14. After sealing the grout pipe 14, the rotating rod 221 can be rotated directly by the turntable 222, so that the turntable can smoothly drive the sealing plate 223 to move inside the mounting frame 211 until the bottom of the sealing plate 223 abuts against the inner bottom of the mounting frame 211, thus completing the sealing of the inside of the mounting frame 211. After sealing the mounting frame 211, the grouting pipe can be disassembled and removed. Compared with the traditional method of using the sealing plug 32 to seal after pulling out the grouting pipe, this sealing method avoids the time difference between removing the sealing plug 32 when removing the grouting pipe, which can cause the concrete grout to flow back and cause air bubbles and holes in the grouting sleeve 1, thereby improving the grouting effect of this device in the later stage.

[0037] The above are merely embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
