Description

Technical Field

[0001] This invention belongs to the field of waterproof construction technology, and specifically relates to a method for waterproof construction of roofs. Background Technology

[0002] The roof refers to the surface of a building's roof, specifically the area between the ridge and the eaves. This part occupies a large area of ​​the roof, or in other words, the roof is the largest section of the roof. It generally includes a cast-in-place concrete floor, a cement mortar leveling layer, a thermal insulation layer, a waterproof layer, a cement mortar protective layer, a drainage system, parapet walls, and lightning protection measures. In special projects, the installation of roof tiles (batterboard) may also be involved.

[0003] Currently, most existing roofs in Chinese cities use precast reinforced concrete slab structures, primarily flat. Due to the large area of ​​the roof, to ensure sufficient time for the poured concrete to cure, improve its strength and quality, and avoid defects such as pits and cracks, it is often necessary to pour the roof concrete in sections.

[0004] However, segmented pouring can easily create gaps at the joints, leading to water seepage in the roof.

[0005] Therefore, a method for roof waterproofing construction is proposed. Summary of the Invention

[0006] The purpose of this invention is to solve the aforementioned technical problems existing in the prior art and to provide a method for roof waterproofing construction. After the concrete of the roof is poured in sections, a foundation pit is opened at the joints at both ends, exposing the square steel within the concrete within the pit. A fitting groove is excavated downwards at the joint gap at the bottom of the pit. A corresponding waterstop strip is prepared according to the size of the fitting groove and is clamped into the fitting groove. Then, a clamping seat is fixed at the bottom of the pit on both sides of the square steel, so that the clamping seat presses against the waterstop strip, thereby limiting and fixing the waterstop strip. A reinforcing frame is set on the clamping seat, and a reinforcing member is set between the two reinforcing frames on both sides of the square steel. The reinforcing member presses against the square steel, and a tightening component is set inside the reinforcing frame, abutting against both ends of the reinforcing member. Through the setting of the reinforcing member and the tightening component, the square steel and the waterstop strip are securely connected. The strips are connected to improve the overall integrity and increase the stability of the sealing strip installation, while also reinforcing the square steel. Next, a retaining wall is built along the edges of both sides of the foundation pit, and then a second pour is made. After the pour is completed, due to the gap between the retaining wall and the edge of the foundation pit, the poured concrete layer can be placed on the two spliced ​​roof sections. The concrete layer increases the contact surface with the roof, thereby improving the stability of the subsequently poured concrete layer. During the pouring of the concrete layer, pre-embedded bolts are installed. Then, step holes are opened on the top surface of the trapezoidal ramp. By installing the ramp onto the concrete layer, the pre-embedded bolts pass through the step holes, and then lock nuts are screwed in to fix it, thus fixing the ramp onto the concrete layer. The ramp covering the concrete layer further improves the waterproofing effect, and at the same time, the ramp can also protect the concrete layer.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A method for waterproofing roofs includes the following steps:

[0009] a. Grooving

[0010] First, a foundation pit is opened at the joint of the two cement floors on the roof, so that the square steel inside the roof is exposed in the foundation pit. Then, a fitting groove is opened again at the joint at the bottom of the foundation pit.

[0011] b. Installation of waterstop strips

[0012] Prepare a waterstop strip of the appropriate size for the size of the fitting groove, and fasten the waterstop strip into the fitting groove;

[0013] c. Fixing of waterstop strips

[0014] 1) Tighten

[0015] By setting a clamping seat, both ends of the clamping seat are fixed to the bottom of the foundation pit. The bottom of the clamping seat is provided with a slot, and the top of the waterstop strip is placed in the slot, so that the clamping seat presses the waterstop strip into the fitting groove.

[0016] 2) Square steel reinforcement

[0017] The clamping seats are set on both sides of the square steel, and the reinforcing frame is set on the top surface of the clamping seats. The reinforcing member is set between the two reinforcing frames on both sides of the square steel. The reinforcing member is pressed against the square steel. The clamping component is set inside the reinforcing frame and the clamping component abuts against the bottom of both ends of the reinforcing member.

[0018] d. Concrete pouring

[0019] Erect enclosure panels on both sides of the foundation pit, with a gap between the enclosure panels and the edge of the foundation pit, so that the two ends of the top surface of the poured concrete layer can be supported on the roof; after pouring, carry out curing, and after curing, remove the enclosure panels;

[0020] e. Ramp installation

[0021] During the pouring process, pre-embedded bolts are installed on the top surface of the concrete layer; the ramp adopts a trapezoidal structure, and step holes are set on the top surface of the ramp. The pre-embedded bolts pass through the step holes, and the top of the pre-embedded bolts is screwed into the locking nut. The locking nut is tightened in the step hole, thereby fixing the ramp to the concrete layer.

[0022] Furthermore, the waterstop strip is made of water-swellable material and has a T-shaped structure. It includes an insert and a limiting part, with the limiting part located at both ends of the top of the insert. The insert and the fitting groove are fitted with water-swellable material, and the limiting part rests against the bottom of the pit. The insert and the limiting part are integrally formed. The waterstop strip is made of water-swellable material, allowing it to expand upon contact with water, completely sealing the fitting groove and improving waterproofing performance. The T-shaped structure allows the limiting parts at both ends to be positioned at the bottom of the pit, while the insert is secured within the fitting groove, increasing the contact area for installation and improving the stability of the waterstop strip.

[0023] Furthermore, the clamping seat includes a clamping part and a fixing part. The fixing part is located at both ends of the clamping part and is integrally formed with the clamping part. The fixing part has stepped holes, and locking screws are screwed into the stepped holes. The locking screws are screwed into the bottom of the foundation pit, so that the fixing part is fixedly connected to the foundation pit. The bottom of the clamping part has a groove, and the top of the waterstop strip is matched with the groove. The waterstop strip is clamped in the groove, so that the clamping part presses the waterstop strip into the foundation pit. The fixing part is used to fix the clamping seat in the foundation pit, and the clamping part clamps onto the waterstop strip, pressing the waterstop strip into the fitting groove, which improves the stability of the waterstop strip installation.

[0024] Furthermore, the reinforcement frame adopts a U-shaped structure, with two ends at the bottom of the frame extending outwards to form fixing blocks. These fixing blocks are tightened onto the top surface of the clamping seat using fastening screws, creating an installation cavity between the reinforcement frame and the clamping seat. The two ends of the reinforcement member are movably connected to the reinforcement frame and are located within the installation cavity, pressing against the top surface of the square steel. The bottom of the clamping assembly is fixedly connected to the bottom surface within the installation cavity, with its top surface pressing against the bottom of both ends of the reinforcement member. The fixing blocks secure the reinforcement frame to the clamping seat, forming an installation cavity for the clamping assembly. The reinforcement member is clamped onto the square steel, connecting the square steel and the foundation pit together through the reinforcement member, the reinforcement frame, and the clamping seat. This ensures the integrity of the square steel and the foundation pit, reinforcing the square steel. The clamping assembly clamps against both ends of the reinforcement member, improving the stability of the reinforcement installation.

[0025] Furthermore, the reinforcement component includes a clamping rod, an adjusting screw, and an adjusting nut. The bottom of the clamping rod presses against the top surface of the square steel. The bottom of the adjusting screw passes through the top of the reinforcement frame and is fixedly connected to both ends of the top of the clamping rod. The adjusting nut is screwed into both ends of the adjusting screw and tightened on the upper and lower sides of the top of the reinforcement frame. By adjusting the screw, the clamping rod is driven to press down, causing it to press against the top surface of the square steel. The adjusting nut then fixes the clamping rod in place, thus completing the reinforcement of the square steel.

[0026] Furthermore, the bottom of the clamping rod is provided with a groove, within which an extension member is rotatably connected. The bottom surface of the extension member is on the same plane as the bottom surface of the clamping rod, ensuring that both the bottom surfaces of the extension member and the clamping rod abut against the top surface of the square steel. The extension member increases the contact area between the reinforcement and the square steel, allowing for multi-angle clamping of the square steel within the same plane, thereby enhancing the reinforcement effect.

[0027] Furthermore, the extension component includes an extension rod, a rotating shaft, and a fastening nut. The extension rod is movably connected within a groove. The bottom of the rotating shaft passes through a clamping rod and is fixedly connected to the top center of the extension rod. The fastening nut is screwed into the rotating shaft and tightened onto the clamping rod. A limiting end is provided at the top of the rotating shaft. The extension rod increases the contact area and allows for the application of clamping forces in two directions on the same plane, thereby reinforcing the square steel. The rotating shaft drives the extension rod to rotate, and after adjustment, the extension rod is fixed by the fastening nut.

[0028] Furthermore, the clamping assembly includes a clamping plate, a lifting component, and a buffer component. The bottom of the lifting component is fixedly connected to the bottom of the mounting cavity, the buffer component is fixedly connected to the lifting component, and the clamping plate is fixedly connected to the top of the buffer component. The top surface of the clamping plate abuts against both ends of the bottom surface of the clamping rod. The lifting component drives the buffer component and the clamping plate to rise and fall, so that the clamping plate abuts against both ends of the bottom surface of the clamping rod. The buffer component plays a buffering role. The clamping assembly abuts against both ends of the clamping rod, increasing the contact area between the reinforcement component and the reinforcement frame, thereby improving the stability of the reinforcement component. At the same time, it increases the integrity of the square steel and the foundation pit, thereby improving the reinforcement effect of the square steel.

[0029] Furthermore, the lifting component includes a fixed base, a lifting screw, and a lifting sleeve. The fixed base is fixedly connected to the clamping base, and the lifting screw is fixedly connected to the top surface of the fixed base. The bottom surface of the lifting sleeve has a slot, the inner wall of which has an internal thread, and the lifting screw has an external thread. The internal and external threads are matched to create a threaded connection between the lifting sleeve and the lifting screw. Through the threaded connection between the lifting sleeve and the lifting screw, the lifting bar can rotate, thereby enabling the lifting of the buffer component and the top clamping plate.

[0030] Furthermore, the buffer component includes a telescopic rod and a telescopic spring. The bottom of the telescopic rod is fixedly connected to the top surface of the lifting sleeve. A positioning sleeve is provided at the bottom of the clamping plate corresponding to the telescopic rod, and the top surface of the telescopic rod is fixedly connected inside the positioning sleeve. The telescopic spring is sleeved on the outside of the telescopic rod, with its two ends abutting against the bottom of the clamping plate and the top of the lifting sleeve, respectively. The telescopic rod acts as a damper, and the extension and retraction of the spring buffers the downward pressure of the clamping rod, preventing it from directly pressing down onto the clamping plate and causing deformation.

[0031] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0032] In step b of this invention, after the concrete of the roof is poured in sections, a foundation pit is opened at the joint of both ends, and the square steel in the concrete is exposed in the foundation pit. A fitting groove is dug downward at the joint gap at the bottom of the foundation pit. According to the size of the fitting groove, a corresponding waterstop strip is prepared. The waterstop strip is clamped in the fitting groove. The setting of the waterstop strip plays a waterproof role in the joint gap, increasing the sealing and waterproof performance between the joint sections.

[0033] In step c of this invention, the clamping seat is fixed at the bottom of the foundation pit on both sides of the square steel, so that the clamping seat presses against the waterstop strip, thereby limiting and fixing the waterstop strip. A reinforcing frame is set on the clamping seat, and a reinforcing member is set between the two reinforcing frames on both sides of the square steel. The reinforcing member presses against the square steel, and a tightening component is set inside the reinforcing frame. The tightening component abuts against both ends of the reinforcing member. Through the setting of the reinforcing member and the tightening component, the square steel and the waterstop strip are connected, which improves the overall integrity, increases the stability of the sealing strip installation, and also reinforces the square steel.

[0034] In step e of this invention, a retaining wall is erected along the edges of both sides of the foundation pit, and then a second pour is made. After the pouring is completed, due to the gap between the retaining wall and the edge of the foundation pit, the poured concrete layer can support the two spliced ​​roof sections. The concrete layer increases the contact surface with the roof, thereby improving the stability of the subsequently poured concrete layer. During the pouring process, pre-embedded bolts are installed in the concrete layer. Then, step holes are opened on the top surface of the trapezoidal ramp. By installing the ramp onto the concrete layer, the pre-embedded bolts pass through the step holes, and then lock nuts are screwed in for fixation, thereby fixing the ramp onto the concrete layer. The ramp covering the concrete layer further improves the waterproofing effect, and at the same time, the ramp can protect the concrete layer.

[0035] In this invention, the reinforcing frame adopts a U-shaped structure. The two ends of the bottom of the reinforcing frame extend outwards to form fixing blocks. These fixing blocks are tightened onto the top surface of the clamping seat by fastening screws, thus forming an installation cavity between the reinforcing frame and the clamping seat. The two ends of the reinforcing member are movably connected to the reinforcing frame and are located within the installation cavity, pressing against the top surface of the square steel. The bottom of the clamping component is fixedly connected to the bottom surface within the installation cavity, with its top surface pressing against the bottom of both ends of the reinforcing member. The fixing blocks are used to fix the reinforcing frame onto the clamping seat. After the reinforcing frame is fixed onto the clamping seat, it forms an installation cavity for installing the clamping component. The reinforcing member is clamped onto the square steel, connecting the square steel and the foundation pit together through the reinforcing member, the reinforcing frame, and the clamping seat, thus ensuring the integrity of the square steel and the foundation pit and providing reinforcement to the square steel. The clamping component clamps against both ends of the reinforcing member, thereby improving the stability of the reinforcing member installation. Attached Figure Description

[0053] c. Fixing of waterstop strips

[0054] 1) Tighten

[0055] By setting a clamping seat 4, both ends of the clamping seat 4 are fixed to the bottom of the foundation pit 1. The bottom of the clamping seat 4 is provided with a slot 5, and the top of the waterstop strip 3 is located in the slot 5, so that the clamping seat 4 presses the waterstop strip 3 into the fitting groove 2.

[0056] 2) Square steel reinforcement

[0057] The clamping seat 4 is set on both sides of the square steel 6. The reinforcing frame 7 is set on the top surface of the clamping seat 4. The reinforcing member 8 is set between the two reinforcing frames 7 on both sides of the square steel 6. The reinforcing member 8 is pressed on the square steel 6. The top clamping component 9 is set inside the reinforcing frame 7. The top clamping component 9 abuts against the bottom of both ends of the reinforcing member 8.

[0058] d. Concrete pouring

[0059] Construct enclosure panels 10 on both sides of the foundation pit 1, with a gap between the enclosure panels 10 and the edge of the foundation pit 1, so that the two ends of the top surface of the poured concrete layer 11 can be supported on the roof 42; after pouring, perform curing, and after curing, remove the enclosure panels 10.

[0060] e. Ramp installation

[0061] During the pouring process, the top surface of the concrete layer 11 is equipped with embedded bolts 12; the ramp 13 adopts a trapezoidal structure, and the top surface of the ramp 13 is provided with step holes. The embedded bolts 12 pass through the step holes, and the top of the embedded bolts 12 is screwed into the locking nut 14. The locking nut 14 is tightened in the step hole, thereby fixing the ramp 13 to the concrete layer 11.

[0062] The waterstop strip 3 is made of water-swellable material and has a T-shaped structure. It includes an insert portion 15 and a limiting portion 16. The limiting portion 16 is located at both ends of the top of the insert portion 15. The insert portion 15 and the fitting groove 2 are fitted with water-swellable material. The limiting portion 16 rests against the bottom surface of the foundation pit 1. The insert portion 15 and the limiting portion 16 are integrally formed. The waterstop strip 3 is made of water-swellable material, which allows it to expand upon contact with water, completely sealing the fitting groove 2 and improving waterproofing performance. The T-shaped structure of the waterstop strip 3 allows the limiting portions 16 at both ends to be positioned at the bottom of the foundation pit 1, while the insert portion 15 is secured within the fitting groove 2, thereby increasing the contact area for installation and improving the stability of the waterstop strip 3.

[0063] The clamping seat 4 includes a clamping part 17 and a fixing part 18. The fixing part 18 is located at both ends of the clamping part and is integrally formed with the clamping part 17 and the fixing part 18. The fixing part 18 has a stepped hole, and a locking screw 19 is screwed into the stepped hole. The locking screw 19 is screwed into the bottom of the pit 1, so that the fixing part 18 is fixedly connected to the pit 1. The bottom of the clamping part 17 has a groove 5. The top of the waterstop strip 3 is matched with the groove 5, and the waterstop strip 3 is clamped in the groove 5, so that the clamping part 17 presses the waterstop strip 3 into the pit 1. The fixing part 18 is used to fix the clamping seat in the pit 1, and the clamping part 17 clamps onto the waterstop strip 3, pressing the waterstop strip 3 into the fitting groove 2, which improves the stability of the installation of the waterstop strip 3.

[0064] The reinforcing frame 7 adopts a U-shaped structure. The two ends of the bottom of the reinforcing frame 7 extend outward to form fixing blocks 20. The fixing blocks 20 are tightened to the top surface of the clamping seat 4 by fastening screws 37, thereby forming an installation cavity 21 between the reinforcing frame 7 and the clamping seat 4. The two ends of the reinforcing member 8 are movably connected to the reinforcing frame 7. The two ends of the reinforcing member 8 are located in the installation cavity 21. The reinforcing member 8 abuts against the top surface of the square steel 6. The bottom of the clamping component 9 is fixedly connected to the bottom surface inside the installation cavity 21. The top surface of the clamping component 9 abuts against the bottom of the two ends of the reinforcing member 8. The fixing block 20 is used to fix the reinforcing frame 7 on the clamping seat 4. After the reinforcing frame 7 is fixed on the clamping seat 4, it forms the mounting cavity 21. The mounting cavity 21 is used for the installation of the clamping component 9. The reinforcing component 8 is clamped on the square steel 6. The square steel 6 and the foundation pit 1 are connected together through the reinforcing component 8, the reinforcing frame 7 and the clamping seat 4, thereby ensuring the integrity of the square steel 6 and the foundation pit 1 and playing a reinforcing role on the square steel 6. The clamping component 9 is clamped on both ends of the reinforcing component 8, thereby improving the stability of the reinforcing component 8.

[0065] The reinforcing component 8 includes a clamping rod 22, an adjusting screw 23, and an adjusting nut 24. The bottom of the clamping rod 22 is pressed against the top surface of the square steel 6. The bottom of the adjusting screw 23 passes through the top of the reinforcing frame 7 and is fixedly connected to both ends of the top of the clamping rod 22. The adjusting nut 24 is screwed into both ends of the adjusting screw 23 and tightened on the upper and lower sides of the top of the reinforcing frame 7. By driving the clamping rod 22 downward through the adjusting screw 23, the clamping rod 22 is pressed against the top surface of the square steel 6. The adjusting nut 24 fixes the clamping rod 22, thereby completing the reinforcement of the square steel 6.

[0066] The bottom of the clamping rod 22 is provided with a groove 25, and an extension member 26 is rotatably connected within the groove 25. The bottom surface of the extension member 26 is on the same plane as the bottom surface of the clamping rod 22, so that the bottom surfaces of both the extension member 26 and the clamping rod 22 abut against the top surface of the square steel 6. The extension member 26 increases the contact area between the reinforcing member 8 and the square steel 6, allowing for multi-angle clamping of the square steel 6 within the same plane, thereby increasing the reinforcement effect of the square steel 6. The extension member 26 includes an extension rod 27, a rotating shaft 28, and a fastening nut 29. The extension rod 27 is movably connected within the groove 25. The bottom of the rotating shaft 28 passes through the clamping rod 22 and is fixedly connected to the top center of the extension rod 27. The fastening nut 29 is screwed into the rotating shaft 28 and tightened onto the clamping rod 22. The top of the rotating shaft 28 is provided with a limiting end 30. The extension rod 27 increases the contact area and allows for the application of clamping forces in two directions on the same plane, thereby reinforcing the square steel 6. The rotating shaft 28 drives the extension rod 27 to rotate, and after the extension rod 27 is adjusted, it is fixed by the fastening nut 29.

[0067] The tightening assembly 9 includes a tightening plate 31, a lifting component 32, and a buffer component 33. The bottom of the lifting component 32 is fixedly connected to the bottom of the mounting cavity 21, the buffer component 33 is fixedly connected to the lifting component 32, and the tightening plate 31 is fixedly connected to the top of the buffer component 33. The top surface of the tightening plate 31 abuts against both ends of the bottom surface of the clamping rod 22. The lifting component 32 drives the buffer component 33 and the tightening plate 31 to rise and fall, so that the tightening plate 31 abuts against both ends of the bottom surface of the clamping rod 22. The buffer component 33 plays a buffering role. The tightening assembly 9 abuts against both ends of the clamping rod 22, increasing the contact area between the reinforcement component 8 and the reinforcement frame 7, thereby improving the stability of the reinforcement component 8. At the same time, it increases the integrity of the square steel 6 and the foundation pit 1, thereby improving the reinforcement effect of the square steel 6. The lifting component 32 includes a fixed base 34, a lifting screw 35, and a lifting sleeve 36. The fixed base 34 is fixedly connected to the clamping base 4, and the lifting screw 35 is fixedly connected to the top surface of the fixed base 34. The bottom surface of the lifting sleeve 36 has a slot, and the inner sidewall of the slot has an internal thread. The lifting screw 35 has an external thread 38. The internal thread and the external thread 38 are matched to make the lifting sleeve 36 and the lifting screw 35 threadedly connected. Through the threaded connection between the lifting sleeve 36 and the lifting screw 35, the lifting bar can rotate, thereby realizing the lifting and lowering of the buffer component 33 and the top clamping plate 31. The buffer component 33 includes a telescopic rod 39 and a telescopic spring 40. The bottom of the telescopic rod 39 is fixedly connected to the top surface of the lifting sleeve 36. The bottom of the clamping plate 31 is provided with a positioning sleeve 41 corresponding to the telescopic rod 39. The top surface of the telescopic rod 39 is fixedly connected inside the positioning sleeve 41. The telescopic spring 40 is sleeved on the outside of the telescopic rod 39, and both ends of the telescopic spring 40 abut against the bottom of the clamping plate and the top of the lifting sleeve 36, respectively. The telescopic rod 39 acts as a damper, and the extension and contraction of the spring buffers the downward pressure of the clamping rod 22, preventing the clamping rod 22 from directly pressing down onto the clamping plate 31 and causing deformation of the clamping rod 22.

[0068] This invention involves creating a foundation pit 1 at the joint of the roof 42, and a fitting groove 2 at the bottom of the foundation pit 1. A waterstop strip 3 is installed within the fitting groove 2, serving as a seal and waterproofing element. A clamping seat 4 is also installed on the waterstop strip 3. A reinforcing frame 7 is installed on the clamping seat 4, and reinforcing members 8 are installed between the reinforcing frames 7. A tightening component 9 is installed within the reinforcing frame 7. The reinforcing members 8 are pressed against the square steel 6, and the tightening component 9 abuts against both ends of the reinforcing members 8. The clamping seat 4 and the reinforcing member 8 are then tightened together. Fastener 8, tightening component 9, and reinforcing component 8 connect the waterstop strip 3 to the square steel, thereby reinforcing the square steel 6 and pressing the waterstop strip 3 into the fitting groove 2, improving the waterproof sealing effect. Supporting plates 10 are installed on both sides of the foundation pit 1 to pour the foundation pit 1. After the pouring is completed, a ramp 13 is installed on the concrete layer 11. The ramp 13 prevents water from accumulating on the concrete layer 11 and also provides protection for the concrete layer 11, further increasing the waterproof effect.

[0069] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
