Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a reinforced connection system for construction joints in underground parking garages. Background Technology

[0002] A construction joint is a joint formed between concrete poured in stages due to design requirements or construction needs. It is not a physical "seam," but rather a bonding surface between the first and second poured concrete sections, created when the first poured concrete exceeds its initial setting time.

[0003] In the Chinese patent application number CN202322503191.0, entitled "A Waterproof Structure for Construction Joints of Concrete Structures", the patent forms fitting grooves on the first and second concrete piles, installs a waterproof frame in the fitting grooves and construction joints, and then rotates the knob to make the screw run, causing the central plate to sink to a designated position. The water-absorbing cotton on both sides of the central plate absorbs water in the two water-absorbing grooves, thereby achieving a good waterproof effect. While the connection structure of the construction joint in this patent and existing technology can play a good role in waterproofing, the waterproof structure usually requires multiple bolts for fixation. When the waterproof structure ages and is damaged, the entire connection structure of the construction joint needs to be disassembled, which is cumbersome and has low maintenance efficiency. Moreover, when the construction joint deforms due to thermal expansion and contraction, the waterproof structure of the existing construction joint connection structure has poor sealing stability, resulting in poor waterproofing of the construction joint. Summary of the Invention

[0004] This invention provides a reinforced connection system for construction joints in basements, which can effectively solve the problem in the prior art mentioned above, where the waterproof structure of the construction joint connection structure needs to be disassembled after aging and damage. This process is cumbersome, has low maintenance efficiency, and results in poor waterproofing stability of the waterproof structure, leading to poor waterproofing of the construction joint.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reinforced connection system for construction joints in a basement, comprising two precast concrete slabs symmetrically distributed, each precast concrete slab being provided with a joint sealing assembly, the joint sealing assembly including a sinking groove; The precast concrete slab is provided with a sinking groove, and a fixing steel plate is fixed to the top of the sinking groove by screws. The top of the fixing steel plate is provided with several toothed grooves. A sealing pipe is connected between two precast concrete slabs, and L-shaped strips are connected to both sides of the sealing pipe. The L-shaped strips are provided with several teeth. A pressure plate is placed on the top of the L-shaped belt, a pressure frame is placed on the top of the pressure plate, and multiple pressure springs are connected at equal intervals on the top surface of the pressure plate. A force-bearing plate is welded to the top of each pressure spring. A panel is installed on the top of the precast concrete slab, and the top surface of the lower pressure plate is in contact with the bottom surface of the panel.

[0006] According to the above technical solution, the top surface of the L-shaped belt is flush with the top surface of the fixed steel plate, and the teeth mesh with the tooth groove.

[0007] According to the above technical solution, the top of the sealing tube is provided with multiple water guiding holes at equal intervals, and a polyurea sealing strip is bonded to the top of the sealing tube between two L-shaped strips.

[0008] According to the above technical solution, the top of the pressure frame is provided with multiple pressure grooves, the pressure spring and the force plate are located inside the pressure grooves, and the top surface of the force plate is in contact with the top surface of the pressure groove.

[0009] According to the above technical solution, a rubber strip is movably embedded between the two lower pressure frames, and a rubber strip is also movably embedded in the gap between one side of the lower pressure frame and the side of the sinking trough.

[0010] According to the above technical solution, multiple mating teeth are provided on the opposite sides of the two panels. The mating teeth are staggered in pairs, and gaps are left between the staggered mating teeth.

[0011] According to the above technical solution, a bearing seat is installed at the bottom of the panel rotation shaft on the top of the precast concrete slab. Multiple U-shaped steel bars are welded at equal intervals at the bottom of the bearing seat. Rotating seats are installed at both ends of the bearing seat on the top of the precast concrete slab. The rotating seats are rotatably connected to the panel rotation shaft. U-shaped steel bars are also welded to the bottom of the rotating seats. The U-shaped steel bars are embedded inside the precast concrete slab.

[0012] According to the above technical solution, the precast concrete slab is provided with a butt joint installation assembly, which includes a steel reinforcement ring; Multiple steel rings are embedded at equal intervals on one side of the precast concrete slab, and several longitudinal steel bars are welded inside the steel rings located on the same side. One of the precast concrete slabs has multiple butt joint steel bars fixed at equal intervals on one side of its bottom, and a rubber sleeve is fitted on the outside of the butt joint steel bars. The other precast concrete slab has multiple butt joint channels at equal intervals on one side of its bottom, and the rubber sleeve and the butt joint steel bars are embedded inside the butt joint channels.

[0013] According to the above technical solution, a plurality of grouting channels are provided at equal intervals inside a precast concrete slab, and the grouting channels are connected to the bottom of the gap between two precast concrete slabs.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A joint sealing assembly is provided. The lower pressure frame is made of iron. Under the action of gravity, the lower pressure frame can apply downward pressure to the lower pressure plate, and the lower pressure frame will squeeze the lower pressure spring. The elastic force of the lower pressure spring acts on the lower pressure plate. The combined action of gravity of the lower pressure plate and the lower pressure frame with the elastic force of the lower pressure spring fully ensures the meshing stability of the teeth and grooves, thereby ensuring the sealing stability of the construction joint. When the sealing tube ages and is damaged, the lower pressure frame, rubber strip, lower pressure plate and sealing tube are all installed in a movable modular manner. During future maintenance, each component is easy to disassemble and assemble. Compared with the existing technology, the connection of the construction joint of this basement is more convenient to maintain and more practical. Multiple water guide holes are evenly spaced at the top of the sealed pipe. A humidity sensor is placed inside the sealed pipe and is electrically connected to an external controller. When the sealed pipe ages and fails, groundwater will enter the sealed pipe through the water guide holes. The humidity sensor will feed back the signal to the external controller. Maintenance personnel can locate the aged and damaged sealed pipe based on the feedback information, making maintenance more convenient. The sealing pipes and L-shaped strips are made of rubber and are installed at the construction joints. When the construction gap deforms due to thermal expansion and contraction, the sealing pipes can elastically deform to follow the changes in the construction gap, ensuring the sealing stability of the construction joints and preventing groundwater from entering the basement floor from the construction joints. The top of the fixed steel plate has several grooves, and the L-shaped strip has several teeth. The teeth and grooves form an arch shape at the joint, which has a larger sealing area. Compared with the existing rubber water-blocking strips, this water-blocking effect is better. Rubber strips are also provided. The rubber strips can seal the joints between the two lower pressure frames and the joints between the two lower pressure frames and the sinkhole, preventing water on the basement floor from flowing into the bottom of the lower pressure frames. At the same time, the rubber strips can also prevent groundwater from entering the basement floor, resulting in a better water-blocking effect.

[0015] 2. It is equipped with a docking installation component. The top of a precast concrete slab with a grouting channel is docked. Polyurea grout is injected into the bottom of the grouting channel and the gap between the two precast concrete slabs through a grouting gun. After the polyurea grout solidifies at the bottom of the gap between the two precast concrete slabs, it prevents groundwater from entering the construction gap between the two precast concrete slabs. When the construction gap deforms due to thermal expansion and contraction, the solidified polyurea grout can elastically deform with the changes in the construction gap, resulting in good sealing stability. One side of the precast concrete slab is equipped with a steel ring and longitudinal reinforcement. During construction, the slurry-like concrete can be directly poured onto the outside of the steel ring and longitudinal reinforcement, making construction convenient and quick. When constructing the new basement floor, another precast concrete slab is connected to the previously installed precast concrete slab. One side of the precast concrete slab has a connecting steel bar at the bottom, and a rubber sleeve is fitted on the outside of the connecting steel bar. The other side of the precast concrete slab has a connecting channel at the bottom. When the two precast concrete slabs are connected, the rubber sleeve matches the connecting channel, making the installation of the two precast concrete slabs simpler and more convenient.

[0016] In summary, the solidified polyurea grout in the joint installation assembly serves as the first line of defense for sealing. In the joint sealing assembly, the sealing pipe and L-shaped strip serve as the second line of defense, and the rubber strip serves as the third line of defense. The three sealing and water-blocking lines work together to fully guarantee the construction quality of the construction joint. Moreover, this construction joint connection structure is simple and convenient to construct and maintain, and has good performance. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example: Figure 1-8 As shown, the present invention provides a technical solution for a reinforced connection system for construction joints in a basement, including a precast concrete slab 1. Two precast concrete slabs 1 are provided and symmetrically distributed. Each precast concrete slab 1 is provided with a joint sealing component 2. The joint sealing component 2 includes a sinking groove 201, a fixing steel plate 202, a toothed groove 203, a sealing pipe 204, an L-shaped strip 205, teeth 206, a water guide hole 207, a polyurea sealing strip 208, a lower pressure plate 209, a lower pressure spring 210, a force-bearing plate 211, a lower pressure frame 212, a lower pressure groove 213, a rubber strip 214, a panel 215, a butt joint tooth 216, a bearing seat 217, a rotating seat 218, and a U-shaped steel strip 219. The precast concrete slab 1 is provided with a sinking groove 201. A fixing steel plate 202 is fixed to the top of the sinking groove 201 by screws. The top of the fixing steel plate 202 is provided with several teeth 203. A sealing pipe 204 is connected between two precast concrete slabs 1. L-shaped strips 205 are connected to both sides of the sealing pipe 204. The L-shaped strips 205 are provided with several teeth 206. The sealing pipe 204 and the L-shaped strips 205 are made of rubber, so that the sealing pipe 204 and the L-shaped strips 205 have good elasticity. Multiple water guide holes 207 are evenly spaced at the top of the sealing pipe 204. A humidity sensor is placed inside the sealing pipe 204 and is electrically connected to an external controller. When the sealing pipe 204 ages and fails, groundwater will enter the sealing pipe 204 through the water guide holes 207. The humidity sensor will feed back the signal to the external controller. Maintenance personnel can locate the aged and damaged sealing pipe 204 based on the feedback information, which will facilitate the subsequent replacement of the sealing pipe 204. A polyurea sealing strip 208 is bonded between two L-shaped strips 205 at the top of the sealing pipe 204. The polyurea sealing strip 208 is formed by curing polyurea grout. The polyurea sealing strip 208 has good elasticity and water-blocking performance. When the sealing pipe 204 ages and fails, the polyurea sealing strip 208 can block groundwater and prevent groundwater from overflowing from the joint. A pressure plate 209, made of iron, is placed on top of the L-shaped belt 205. The top surface of the L-shaped belt 205 is flush with the top surface of the fixed steel plate 202. The teeth 206 and the grooves 203 mesh with each other. The pressure plate 209 can fix the teeth 206 and the grooves 203 in a fixed engagement, making the L-shaped belt 205 more secure. The joint between the teeth 206 and the grooves 203 forms an arc shape. When there is water at the bottom of the sealing pipe 204, the arc-shaped joint has a larger sealing area and a better sealing effect. A pressure bracket 212 is placed on top of the pressure plate 209. Multiple pressure springs 210 are connected at equal intervals on the top surface of the pressure plate 209. A force-bearing plate 211 is welded to the top of the pressure springs 210. The top of the pressure frame 212 is provided with multiple pressure grooves 213. The pressure spring 210 and the force plate 211 are located inside the pressure grooves 213. The top surface of the force plate 211 is in contact with the top surface of the pressure groove 213. The pressure frame 212 is made of iron. Under the action of gravity, the pressure frame 212 can apply downward pressure to the pressure plate 209, and the pressure frame 212 will squeeze the pressure spring 210. The elastic force of the pressure spring 210 reacts on the pressure plate 209. The gravity of the pressure plate 209 and the pressure frame 212, combined with the elastic force of the pressure spring 210, fully ensures the meshing stability of the teeth 206 and the grooves 203, thereby ensuring the sealing stability of the construction joint. A panel 215 is installed on the top of the precast concrete slab 1. The top surface of the lower pressure plate 209 is in contact with the bottom surface of the panel 215. Multiple butt teeth 216 are provided on the opposite sides of the two panels 215. The butt teeth 216 are staggered and there is a gap between the staggered butt teeth 216. When the concrete floor expands and contracts due to temperature changes, the width at the construction joint will change. The gap between the butt teeth 216 can provide deformation space for the changes at the contact point. A rubber strip 214 is movably embedded between the two lower pressure frames 212. A rubber strip 214 is also movably embedded in the gap between one side of the lower pressure frame 212 and the side of the sink trough 201. The rubber strip 214 has good elasticity and can seal the joint between the two lower pressure frames 212 and the joint between the two lower pressure frames 212 and the sink trough 201, preventing water on the ground floor from flowing into the bottom of the lower pressure frame 212. At the same time, the rubber strip 214 can also prevent groundwater from entering the ground floor. Panel 215 is made of iron and serves as a support on the basement floor. A bearing seat 217 is installed at the bottom of the rotating shaft of panel 215 on the top of precast concrete slab 1. Multiple U-shaped steel bars 219 are welded at equal intervals at the bottom of bearing seat 217. Rotating seats 218 are installed at both ends of bearing seat 217 on the top of precast concrete slab 1. Rotating seats 218 are rotatably connected to the rotating shaft of panel 215. U-shaped steel bars 219 are also welded to the bottom of rotating seats 218. The U-shaped steel bars 219 are embedded inside the precast concrete slab 1. The U-shaped steel bars 219 can make the rotating seats 218 and bearing seats 217 more firmly fixed on the precast concrete slab 1. Bearing seat 217 can provide support for panel 215 and prevent the rotating shaft from bending when panel 215 is subjected to greater pressure, thus ensuring the rotational stability of panel 215. The precast concrete slab 1 is provided with a butt joint installation component 3, which includes a steel ring 301, longitudinal steel bars 302, butt joint steel bars 303, rubber sleeve 304, butt joint channel 305 and grouting channel 306; Multiple steel rings 301 are embedded at equal intervals on one side of the precast concrete slab 1, and several longitudinal steel bars 302 are welded inside the steel rings 301 on the same side. Multiple butt joint steel bars 303 are fixed at equal intervals on one side of the bottom of a precast concrete slab 1. A rubber sleeve 304 is fitted over the outside of the butt joint steel bars 303. Multiple butt joint channels 305 are opened at equal intervals on one side of the bottom of another precast concrete slab 1. The rubber sleeve 304 and the butt joint steel bars 303 are embedded in the butt joint channels 305. Multiple grouting channels 306 are set at equal intervals inside one precast concrete slab 1. The grouting channels 306 are connected to the bottom of the gap between the two precast concrete slabs 1. The grouting gun head is connected to the top of the grouting channel 306. Polyurea grout is injected into the grouting channel 306 and the bottom of the gap between the two precast concrete slabs 1 through the grouting gun. After the polyurea grout solidifies at the bottom of the gap between the two precast concrete slabs 1, the solidified polyurea grout can further improve the sealing effect of the construction joint.

[0021] The working principle and usage process of this invention: During the construction of the old basement floor, a precast concrete slab 1 is pre-installed at the construction joint position during the floor pouring, so that the panel 215 is flush with the ground. A steel ring 301 and longitudinal steel bars 302 are provided on one side of the precast concrete slab 1. During the concrete pouring, the slurry concrete wraps around the steel ring 301 and longitudinal steel bars 302. After the concrete solidifies, the precast concrete slab 1 can be firmly bonded and fixed to the concrete. When constructing the new basement floor, another precast concrete slab 1 is joined to the previously installed precast concrete slab 1. A connecting steel bar 303 is provided on the bottom side of one precast concrete slab 1, and a rubber sleeve 304 is sleeved on the outside of the connecting steel bar 303. A connecting channel 305 is provided on the bottom side of the other precast concrete slab 1. When the two precast concrete slabs 1 are joined, the rubber sleeve 304 and the connecting channel 305 are matched and joined. The installation of the two precast concrete slabs 1 is simpler and more convenient. After the two precast concrete slabs 1 are joined, the concrete floor of the new basement can be poured. Then, rotate panel 215 to open it, and use screws to fix the fixing steel plate 202 to the top of the sink trough 201. Next, install the sealing tube 204, L-shaped belt 205, lower pressure plate 209, lower pressure bracket 212 and rubber strip 214 in sequence. After installation, lower panel 215. Subsequently, the grouting gun head is connected to the top of the grouting channel 306, and the polyurea grout is injected into the bottom of the gap between the grouting channel 306 and the two precast concrete slabs 1 through the grouting gun. After the polyurea grout solidifies at the bottom of the gap between the two precast concrete slabs 1, the solidified polyurea grout serves as the first line of defense to prevent groundwater from entering the construction gap between the two precast concrete slabs 1. When the construction gap deforms due to thermal expansion and contraction, the solidified polyurea grout can elastically deform with the changes in the construction gap, resulting in good sealing stability. The sealing pipe 204 and L-shaped strip 205 are made of rubber, giving them good elasticity. As a second line of defense, the sealing pipe 204 and L-shaped strip 205 prevent groundwater from entering the basement floor through the construction joint. When the construction gap deforms due to thermal expansion and contraction, the sealing pipe 204 can elastically deform to follow the changes in the construction gap, further ensuring the sealing stability of the construction joint. The top of the fixed steel plate 202 has several grooves 203, and the L-shaped strip 205 has several teeth 206. The teeth 206 mesh with the grooves 203, and the joint between the teeth 206 and the grooves 203 forms an arc shape. When there is water at the bottom of the sealing pipe 204, the arc-shaped joint has a larger sealing area and a better sealing and waterproofing effect. A rubber strip 214 is movably embedded between the two lower pressure frames 212, and a rubber strip 214 is also movably embedded in the gap between one side of the lower pressure frame 212 and the side of the sinking trough 201. The rubber strip 214 has good elasticity and serves as the third sealing line. The rubber strip 214 can seal the joint between the two lower pressure frames 212 and the joint between the two lower pressure frames 212 and the sinking trough 201, preventing water on the ground floor from flowing into the bottom of the lower pressure frame 212. At the same time, the rubber strip 214 can also prevent groundwater from entering the ground floor. The solidified polyurea grout serves as the first sealing line, the sealing pipe 204 and the L-shaped strip 205 serve as the second sealing line, and the rubber strip 214 serves as the third sealing line. The three sealing and water-blocking lines work together to fully ensure the construction quality of the construction joint. The lower pressure frame 212 is made of iron. Under the action of gravity, the lower pressure frame 212 can apply downward pressure to the lower pressure plate 209, and the lower pressure frame 212 will compress the lower pressure spring 210. The elastic force of the lower pressure spring 210 reacts on the lower pressure plate 209. The combined action of gravity of the lower pressure plate 209 and the lower pressure frame 212 with the elastic force of the lower pressure spring 210 fully ensures the meshing stability of the teeth 206 and the grooves 203, thereby ensuring the sealing stability of the construction joint. When the sealing tube 204 ages and is damaged... When it malfunctions, open panel 215, remove the lower pressure bracket 212, rubber strip 214 and lower pressure plate 209, remove the old sealing tube 204 and L-shaped belt 205, and reinstall the new sealing tube 204 and L-shaped belt 205. The lower pressure bracket 212, rubber strip 214, lower pressure plate 209 and sealing tube 204 are not fixed with bolts, making it easy to disassemble and assemble each component during future maintenance. Compared with existing technology, the connection of the construction joint of the basement is more convenient to maintain and more practical. Multiple water guide holes 207 are evenly spaced at the top of the sealing pipe 204. A humidity sensor is placed inside the sealing pipe 204 and is electrically connected to an external controller. When the sealing pipe 204 ages and fails, groundwater will enter the sealing pipe 204 through the water guide holes 207. The humidity sensor will feed back the signal to the external controller. Maintenance personnel can locate the aged and damaged sealing pipe 204 based on the feedback information, making maintenance more convenient.

[0022] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
