Description

Technical Field

[0001] This invention relates to the field of waterproofing technology for building floor expansion joints, specifically to an integrated waterproofing structure for building floor expansion joints. Background Technology

[0002] Due to factors such as temperature changes, uneven settlement, and earthquakes, additional stress will be generated inside the building structure. This stress often causes cracks or even damage to the building. To reduce the impact of stress on the building, the structure is pre-disconnected in the deformation-sensitive parts during the design phase, leaving gaps, namely expansion joints, to ensure that the disconnected parts of the building have sufficient deformation space to prevent damage or cracks. Waterproofing at expansion joints has always been a challenge in design and construction. Currently, when waterproofing expansion joints at the building's ground location, the common method is to cover the joint with galvanized iron sheet and then add a waterproof membrane layer. However, this waterproofing method is not ideal, unreliable, and has a short service life. Summary of the Invention

[0003] The purpose of this invention is to provide an integral waterproof structure for building floor expansion joints in order to solve the above-mentioned problems. The structure has a groove between both sides of the expansion joint body for placing a fixing and limiting pressure seat. By placing the limiting pressure seat, the roll material laid on top of the expansion joint body is pressed and fixed. The roll material then provides waterproof protection for the expansion joint body. The placement method of the limiting pressure seat is simple and easy to operate, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention provides an integral waterproofing structure for building floor expansion joints, comprising an expansion joint body and a roll of material. The expansion joint body is arranged longitudinally along its length, and both sides of the top of the expansion joint body have longitudinally spaced grooves, with the tops of the grooves open.

[0006] The expansion joint body is covered with a roll of material for waterproofing along the longitudinal direction above the top surface, and the two sides of the roll of material cover the placement groove.

[0007] A waterproof and seepage-proof structure is fixedly arranged between the top of the installation groove, and the waterproof and seepage-proof structure presses the edge of the roll material tightly against the expansion joint body and the installation groove.

[0008] Preferably, the seepage-proof and waterproof structure includes seepage-proof boards and limiting pressure seats. There are multiple seepage-proof boards, all of which are arranged longitudinally. Adjacent seepage-proof boards are connected together by disassembly and assembly components. Mounting wing plates are horizontally extended and fixed to the bottom of both sides of the seepage-proof board. The limiting pressure seats are arranged longitudinally and horizontally below the mounting wing plates on both sides. The limiting pressure seats are suspended above the adjacent placement slots and are placed in the corresponding placement slots in a vertical sliding fit. The mounting wing plates, the limiting pressure seats, and the placement slots are all vertically provided with multiple connecting holes, which are vertically coaxially aligned. Bolts are installed through each set of aligned connecting holes to press the edge of the roll material tightly against the expansion joint body and the placement slot by the limiting pressure seats.

[0009] Preferably, the top surface of the impermeable plate is sloping, and the front and rear end faces of adjacent impermeable plates are in contact with each other, and the end faces of adjacent limiting pressure seats are also in contact with each other.

[0010] Preferably, the connecting holes in the mounting wing plate and the limiting pressure seat are through holes, and the connecting holes in the mounting groove with the bottom facing downward are blind holes that pass through the edge of the roll material.

[0011] Preferably, the bottom surface of the seepage-proof board is covered and fixed with a flexible water-stop frame, and the top surface of the limiting pressure seat on both sides is vertically opened in the longitudinal direction at the part that is close to each other, and the edge of the flexible water-stop frame is attached and pressed tightly to the adjacent limiting groove.

[0012] Preferably, the flexible waterstop frame is rectangular and its thickness is not less than the vertical groove depth of the limiting groove, and the width between the limiting grooves on both sides matches the width of the flexible waterstop frame.

[0013] Preferably, the front and rear ends of the roll material extend beyond the front and rear ends of the expansion joint body, and the outer end faces of the waterproofing board at the front and rear ends are provided with end pressure plates parallel to each other. Both the end pressure plates and the waterproofing board have several butt holes along the longitudinal direction and are respectively aligned longitudinally. Furthermore, the portion of the end pressure plate that is higher than the top surface of the waterproofing board has several wall fixing holes along the longitudinal direction.

[0014] Preferably, each of the assembly and disassembly components includes a mating block and a mating groove. The mating blocks and mating grooves are fixed longitudinally on the opposite end faces of the front and rear adjacent geomembranes, and the mating blocks slide longitudinally with the corresponding mating grooves. Each mating block has a limiting hole in the vertical direction. Each bottom surface of the geomembrane has a mounting hole in the vertical direction. The mounting hole and the limiting hole are vertically coaxially aligned, and each set of aligned mounting holes and limiting holes is vertically coaxially interlocked with a locking component.

[0015] Preferably, all locking components are bolts, and both the mounting hole and the limiting hole are internally threaded holes.

[0016] Preferably, the cross-sectional shape of the mating block and the mating groove along the horizontal and vertical planes are both rectangular, the mating grooves are all blind grooves in the longitudinal direction and are opened from front to back, and the rear end of the mating block is in close contact with the rear end of the corresponding mating groove.

[0017] The above-mentioned integrated waterproofing structure for building ground expansion joints utilizes a method where, during the installation of the expansion joint body, grooves are created on both sides of the expansion joint body to hold and fix the limiting pressure seats. This method of placing the limiting pressure seats securely presses and fixes the rolled material laid on top of the expansion joint body, thereby providing waterproof protection for the expansion joint body. The placement of the limiting pressure seats is simple and easy to operate, facilitating the rapid installation and flattening of the rolled material to waterproof the expansion joint body. Waterproof protection is achieved through a method where the flexible water-stopping frames on both sides of the bottom surface of the waterproof plate are vertically slidably engaged with the limiting grooves on the top of the limiting pressure seats. Bolts are then installed through the connecting holes to press and fix the waterproof plate between the limiting pressure seats on both sides. This method of fixing the waterproof plate between the limiting pressure seats is simple and easy to operate. Furthermore, the flexible water-stopping frames are elastically pressed into the limiting grooves by the waterproof plate, further enhancing the waterproof protection of the expansion joint body. The longitudinal horizontal sliding engagement between the mating block and the mating groove, and the coaxial engagement between the locking member and the limiting hole through the mounting hole, enable rapid assembly of adjacent geomembranes. This assembly method is simple and easy to implement, facilitating the combination of multiple geomembranes into a unified structure conforming to the length of the expansion joint for deployment. Subsequently, simply disengaging the locking member from the limiting hole allows the mating block to disengage from the mating groove, separating adjacent geomembranes. This disassembly method is simple and easy to operate, facilitating subsequent repair of damaged geomembranes. Each individual waterproofing board can be replaced separately. Since the outer end face of the waterproofing board and the end pressure plate are both longitudinally provided with the docking holes, the end pressure plate can be fixed to the waterproofing board at the end position by adding bolts through the docking holes. Then, by setting the end pressure plate, the end of the roll material can be turned up and pressed tightly to the bottom position of the wall connecting to the ground. It can also be fixed to the wall by adding bolts through the wall fixing holes. This ensures that the roll material can also provide waterproof protection for the expansion joint body at the bottom position of the wall connecting to the ground.

[0018] The beneficial effects are as follows: 1. The present invention opens a groove between both sides of the expansion joint body to place a fixed limiting pressure seat. In this way, the roll material laid between the top of the expansion joint body is pressed and fixed by placing the limiting pressure seat. Then, the expansion joint body is protected against seepage and water by setting the roll material. The placement method of the limiting pressure seat is simple and easy to operate, and it is convenient to quickly lay and flatten the roll material to protect the expansion joint body from seepage and water.

[0019] 2. The waterproofing board is positioned by vertically sliding the flexible water-stopping frame on both sides of the bottom surface of the waterproofing board and the limiting groove on the top of the limiting pressure seat. The waterproofing board can be pressed and fixed between the limiting pressure seats on both sides by adding bolts through the connecting holes. The fixing combination of the waterproofing board between the limiting pressure seats is simple and easy to operate. In addition, the flexible water-stopping frame is elastically pressed into the limiting groove by the waterproofing board to further improve the waterproofing protection of the expansion joint body.

[0020] 3. The rapid combination of adjacent geomembranes can be achieved by the longitudinal horizontal sliding fit between the mating block and the mating groove, and the coaxial fit between the locking part and the limiting hole through the mounting hole. The combination of adjacent geomembranes is simple and easy to implement, which makes it easy to combine multiple geomembranes into an overall structure that conforms to the length of the expansion joint for deployment. Afterwards, the mating block can be dislodged from the mating groove by simply dislodging the locking part from the limiting hole, thus separating the two adjacent geomembranes. The method of separating adjacent geomembranes is simple and easy to operate, which facilitates the individual replacement of damaged single geomembranes in the later stage.

[0021] 4. The outer end face of the waterproofing board and the end pressure plate are provided with joint holes along the longitudinal direction. The end pressure plate can be fixed to the waterproofing board at the end position by bolts through the joint holes. Then, the end of the roll material can be turned up and pressed tightly at the bottom of the wall connected to the ground by the setting of the end pressure plate, so as to ensure that the roll material can also provide waterproof protection for the expansion joint at the bottom of the wall connected to the ground.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] See Figures 1-11As shown, the present invention provides an integral waterproof structure for building floor expansion joints, including an expansion joint body 5 and a roll material 2. The expansion joint body 5 is arranged longitudinally along its length, and installation grooves 501 are longitudinally formed on both sides of the top of the expansion joint body 5, with the top of the installation grooves 501 open. A roll material 2 for covering and waterproofing is laid horizontally on the top surface of the expansion joint body 5, and the two sides of the roll material 2 cover the installation grooves 501. A waterproof and seepage-proof structure 1 is fixedly arranged between the top of the installation groove 501. The waterproof and seepage-proof structure 1 presses the edge of the roll material 2 tightly against the expansion joint body 5 and the installation groove 501. Specifically, the waterproof and seepage-proof structure 1 includes a waterproof and seepage-proof plate 103 and a limiting pressure seat 105. There are multiple waterproof and seepage-proof plates 103, all of which are arranged longitudinally. The waterproof and seepage-proof plates 103 adjacent to each other are connected together by a disassembly and assembly component 6. The bottom of both sides of the waterproof and seepage-proof plate 103 are horizontally extended and fixed with mounting wing plates 102. The mounting wing plates 102 on both sides are horizontally arranged longitudinally below them. The limiting pressure seats 105 are all suspended above the adjacent installation grooves 501. The roll material 2 is placed in the corresponding placement slot 501 in a vertical sliding fit. The mounting wing plate 102, the limiting pressure seat 105 and the placement slot 501 are all vertically provided with multiple connecting holes 101, which are vertically coaxially aligned. The limiting pressure seat 105 presses the edge of the roll material 2 tightly against the expansion joint body 5 and the placement slot 501 by installing bolts through each set of corresponding connecting holes 101. This arrangement makes it easy to press and fix the roll material 2 laid on the top of the expansion joint body 5 by placing the limiting pressure seat 105. Then, the roll material 2 is used to achieve waterproof protection for the expansion joint body 5. At the same time, it is easy to quickly lay and flatten the roll material 2 to protect the expansion joint body 5 from seepage and water.

[0038] Specifically, the aforementioned disassembly and assembly component 6 includes a mating block 603 and a mating groove 601. Adjacent front and rear impermeable plates 103 have mating blocks 603 and mating grooves 601 longitudinally fixed on their opposite end faces, respectively. The mating blocks 603 slide longitudinally with their corresponding mating grooves 601. Each mating block 603 has a vertically extending limit hole 602. Each bottom surface of the impermeable plate 103 has a vertically extending mounting hole 604. The mounting holes 604 and limit holes 602 are vertically coaxially aligned. Each pair of aligned mounting holes 604 and limit holes 602 is vertically coaxially interlocked with a locking element 605. This arrangement facilitates the longitudinal horizontal sliding engagement of the mating blocks 603 and mating grooves 601, and allows the locking element 605 to pass through the mounting holes. The coaxial engagement of 604 and the limiting hole 602 enables rapid assembly between adjacent geomembranes 103. Subsequently, the locking piece 605 can be disengaged from the limiting hole 602 to allow the mating block 603 to disengage from the mating groove 601, thus separating the two adjacent geomembranes 103. It should be noted that when replacing a damaged geomembrane 103, the disassembly operation should begin from the end pressure plate 3 near the end of the damaged geomembrane 103 until the damaged geomembrane 103 is disassembled and replaced. After replacement, the parts should be restored until the end pressure plate 3 is fixed back to the wall. It should also be noted that during the installation process, the mating block 603 at the end of the outermost geomembrane 103 can be completely cut off.

[0039] As the preferred embodiment in this case, the top surfaces of the geomembrane 103 are all sloping, and the front and rear end faces of adjacent geomembranes 103 are in contact with each other. The end faces of adjacent limiting seats 105 are also in contact with each other. The purpose of this arrangement is twofold: firstly, the sloping top surface of the geomembrane 103 allows water at the top of the geomembrane 103 to flow smoothly to both sides; secondly, the contact between the front and rear end faces of adjacent geomembranes 103 provides a clear indication when the wing plates 10 are installed. The connecting hole 101 of the 2 and the limiting pressure seat 105 is a through hole, and the connecting hole 101 of the bottom of the placement groove 501 is a blind hole that passes through the edge of the roll material 2. This setting makes it easy to fix the seepage barrier 103 and the limiting pressure seat 105 together at the bottom of the placement groove 501 after the bolts are driven into each set of corresponding connecting holes 101. This achieves the fixed arrangement of the seepage barrier 103 and the limiting pressure seat 105 at the position of the expansion joint body 5. Preferably, the bolts driven into the groove are hexagonal bolts, and the top end of the bolt should be able to be pressed against the surface of the mounting wing plate 102 after it is driven into the groove.

[0040] Meanwhile, the bottom surface of the waterproofing board 103 is covered and fixed with flexible water-stopping frames 104. The top surfaces of the limiting pressure seats 105 on both sides have vertically spaced limiting grooves 106 at their closest points. The edges of the flexible water-stopping frames 104 are pressed tightly against the adjacent limiting grooves 106. This arrangement facilitates the enhancement of the waterproofing capability at the junction of the waterproofing board 103 and the limiting pressure seats 105 by pressing the flexible water-stopping frames 104 against the limiting grooves 106, preventing seepage and water damage when the installation is completed. Subsequently, water seepage and leakage occurred at the joint between the seepage-proof board 103 and the limiting pressure seat 105. The flexible water-stop frame 104 is a rectangular frame with a thickness not less than the vertical groove depth of the limiting groove 106. The width between the limiting grooves 106 on both sides matches the width of the flexible water-stop frame 104, so that the flexible water-stop frame 104 can further improve the seepage-proof and waterproofing ability at the joint between the seepage-proof board 103 and the limiting pressure seat 105 through its own elastic deformation after being pressed.

[0041] Furthermore, the front and rear ends of the roll material 2 extend beyond the front and rear ends of the expansion joint body 5. The outer end faces of the waterproofing board 103 at both ends are parallel to each other with end pressure plates 3. Both the end pressure plates 3 and the waterproofing board 103 have several longitudinally aligned butt joint holes 4. The portion of the end pressure plate 3 above the top surface of the waterproofing board 103 has several longitudinally aligned wall fixing holes 301. This design allows the end of the roll material 2 to be flipped up and pressed against the bottom of the wall connecting to the ground by the end pressure plates 3, and then fixed to the wall by bolts inserted through the wall fixing holes 301. All locking components 605 are bolts, and both the mounting hole 604 and the limiting hole 602 are internally threaded holes, allowing the locking components 605 to pass through... The mounting hole 604 and the limiting hole 602 are quickly assembled and disassembled through threaded engagement. The cross-sectional shape of the mating block 603 and the mating groove 601 along the horizontal and vertical planes is rectangular. The mating groove 601 is a blind groove in the longitudinal direction and is opened from front to back. The rear end of the mating block 603 is in close contact with the rear end of the corresponding mating groove 601. The purpose of this design is to ensure that the mating groove 601 has a good positioning and guiding design to ensure that the mating block 603 is properly aligned and assembled during the mating process of the mating block 603 and the mating groove 601. At the same time, when the end faces of adjacent waterproofing plates 103 are in close contact with each other, the contact between the rear end of the mating block 603 and the rear end of the mating groove 601 provides a clear indication of the alignment.

[0042] Using the above structure, specifically during the installation process at the location of the expansion joint body 5, since installation grooves 501 are opened between both sides of the expansion joint body 5 to place and fix the limiting pressure seat 105, the roll material 2 laid on top of the expansion joint body 5 can be pressed and fixed by placing the limiting pressure seat 105. Subsequently, the installation of the roll material 2 achieves waterproof protection for the expansion joint body 5. The installation method of the limiting pressure seat 105 is simple and easy to operate, facilitating the quick and easy laying and flattening of the roll material 2 to provide waterproof protection for the expansion joint body 5. At the same time, due to the two sides of the bottom surface of the waterproof board 103 The flexible waterstop frame 104 on the side and the limiting groove 106 on the top of the limiting pressure seat 105 are positioned and placed vertically in a sliding fit. The seepage-proof plate 103 can be pressed and fixed between the limiting pressure seats 105 on both sides by bolts installed through the connecting hole 101. The fixing method of the seepage-proof plate 103 between the limiting pressure seats 105 is simple and easy to operate. Furthermore, by using the seepage-proof plate 103 to elastically press the flexible waterstop frame 104 into the limiting groove 106, the seepage-proof plate 103 further enhances the seepage-proof and waterproof protection effect on the expansion joint body 5. Moreover, due to the mating block 603 and the mating groove... The longitudinal horizontal sliding fit of 601 and the coaxial engagement of the locking element 605 through the mounting hole 604 and the limiting hole 602 enable the rapid assembly of adjacent seepage-proof plates 103. This assembly method is simple and easy to implement, facilitating the combination of multiple seepage-proof plates 103 into a unified structure conforming to the length of the expansion joint body 5 for deployment. Subsequently, simply disengaging the locking element 605 from the limiting hole 602 allows the mating block 603 to disengage from the mating groove 601, separating the two adjacent seepage-proof plates 103. This disassembly method is simple and easy to operate, facilitating subsequent... Damaged individual waterproofing boards 103 are replaced individually. Since the outer end face of the waterproofing board 103 and the end pressure plate 3 are both longitudinally provided with connecting holes 4, the end pressure plate 3 can be fixed to the waterproofing board 103 at the end position by adding bolts through the connecting holes 4. Then, by setting the end pressure plate 3, the end of the roll material 2 can be turned up and pressed tightly to the bottom position of the wall connected to the ground. It can be fixed by adding bolts to the wall through the wall fixing holes 301. This ensures that the roll material 2 can also provide waterproof protection for the expansion joint body 5 at the bottom position of the wall connected to the ground.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
