Description

Technical Field

[0001] This invention belongs to the field of post-pouring strip construction technology, and specifically relates to an integrated aluminum formwork waterproof structure and waterproof construction process for post-pouring strips. Background Technology

[0002] Cast-in-place reinforced concrete structures are widely used in industrial and civil buildings due to their advantages such as good integrity, superior seismic performance, and flexible spatial arrangement. However, these structures typically have large planar dimensions and are prone to deformation during the hardening process due to the combined effects of multiple factors, including drying shrinkage, autogenous shrinkage, plastic shrinkage, chemical shrinkage, and temperature shrinkage. Furthermore, uneven settlement between the main building and the podium often induces harmful cracks that threaten structural safety. To effectively release temperature stress and regulate differential settlement, post-cast strip segmented construction techniques are commonly used in engineering projects.

[0003] Taking Chinese patent CN110439035B as an example, the disclosed method for waterproofing the post-cast strip of the basement floor includes the following steps: foundation cushion layer construction; SBS waterproofing additional layer and waterproofing layer construction; cement mortar protective layer construction; installation of steel reinforcement support frame, waterstop steel plate and quick-closing mesh; installation of water-swellable waterstop strip; installation of steel frame; pouring of self-waterproof structural floor slab; installation of protective wooden board for post-cast strip; and concrete sealing construction of post-cast strip.

[0004] In conventional construction of post-pouring strips, wooden formwork or wire mesh formwork is often used for formwork support on both sides. However, both have significant drawbacks: wooden formwork needs to be removed before subsequent pouring, which is a complicated process; and to ensure ease of removal, wooden formwork is usually assembled in sections, resulting in low support rigidity, easy formwork displacement, and easy grout leakage at the joints. Wire mesh formwork, due to its mesh structure, also struggles to avoid the risk of grout leakage. Furthermore, regardless of the traditional formwork used, it complicates subsequent waterproofing work in the post-pouring strip area, often requiring the waterstop strips to be installed later, which is prone to displacement and premature expansion failure, making the interface between the old and new concrete a weak point in terms of impermeability and easily leading to leakage risks. Summary of the Invention

[0005] In response to the problems in related technologies, this invention proposes an integrated aluminum formwork waterproof structure and waterproof construction process for post-pouring strips, in order to overcome the aforementioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an integrated aluminum formwork waterproof structure for post-pouring strips, comprising a pair of non-removable aluminum alloy side formworks, multiple lifting and adjustable support columns, and an aluminum alloy cover plate. The pair of non-removable aluminum alloy side formworks are longitudinally arranged on both sides along the post-pouring strip area. The side of the non-removable aluminum alloy side formworks facing the post-pouring strip area is provided with stiffening ribs, and the side of the non-removable aluminum alloy side formworks facing the first-poured concrete is provided with a sealing water-stop strip. The non-removable aluminum alloy side formworks are provided with through grooves for the steel bars in the steel bar support mesh to pass through, and the top surface of the non-removable aluminum alloy side formworks is provided with a slot. Multiple lifting and adjustable support columns are horizontally distributed and installed on the side of the non-removable aluminum alloy side formwork facing the post-pouring strip area, for supporting and positioning the non-removable aluminum alloy side formwork, and each of the lifting and adjustable support columns can be lifted and adjusted. The width of the aluminum alloy cover plate is greater than the width of the post-pouring strip area. The bottom surfaces on both sides of the aluminum alloy cover plate are provided with locking blocks that respectively engage with the top slots of a pair of non-removable aluminum alloy side templates. The locking blocks and slots are fitted with a gap. The aluminum alloy cover plate and the locking blocks are provided with glue injection channels that can communicate with the slots.

The glue injection hole is disposed inside the aluminum alloy cover plate, and one end of the glue injection hole is connected to the guide groove. The other end of the glue injection hole extends to the surface of the aluminum alloy cover plate. Multiple guide holes distributed along the guide groove are provided on both sides of the card block. One end of the guide hole is connected to the guide groove, and the other end of the guide hole can be connected to the card slot.

[0009] Preferably, the upper end of the non-removable aluminum alloy side template facing the pre-poured concrete is provided with a plurality of glue outlet holes evenly distributed along the slot. One end of the glue outlet hole is connected to the slot, and the other end of the glue outlet hole is connected to the pouring gap between the non-removable aluminum alloy side template and the pre-poured concrete, so that the sealant injected into the slot can be delivered along the glue outlet hole to fill the pouring gap between the non-removable aluminum alloy side template and the pre-poured concrete.

[0010] Preferably, a pressure check valve is installed in the glue outlet hole, with the conveying direction facing the direction of the first poured concrete. The pressure check valve can seal the glue outlet hole, and the pressure check valve can also be automatically opened under the hydraulic drive of the sealant in the slot, so that the sealant in the slot can be squeezed and conveyed to the pouring gap between the non-removable aluminum alloy side formwork and the first poured concrete through the pressure check valve. The pressure check valve is made of elastic rubber material, and the side of the pressure check valve facing the slot is open, while the side of the pressure check valve facing the first poured concrete is flat.

[0011] Preferably, the top surface of the aluminum alloy cover plate is provided with multiple concrete pouring ports distributed at equal intervals, and each concrete pouring port is equipped with a sealing cap.

[0012] Preferably, the adjustable support column includes a support sleeve, a base is fixedly installed on the bottom surface of the support sleeve, the base can be anchored to the top surface of the lower support base, a lifting support component is installed on the top of the support sleeve, the top of the lifting support component is fixedly connected to the non-removable aluminum alloy side template, and the lifting support component can be adjusted up and down along the support sleeve so that the lifting support component can adjust the non-removable aluminum alloy side template.

[0013] Preferably, a plurality of circumferentially distributed reinforcing plates are fixedly installed between the bottom end of the support sleeve and the base, and the base is provided with positioning holes so that the base can be anchored to the top surface of the lower support base by anchor bolts passing through the positioning holes.

[0014] Preferably, the support sleeve has an internal telescopic groove, and the top of the telescopic groove has a rotary table mounting groove. The lifting support includes a rotating platform, which is rotatably assembled in a rotating platform mounting slot. A nut is fixedly installed on the top surface of the rotating platform. A support screw is rotatably installed on the inner ring of the nut through an internal thread. The bottom end of the support screw passes through the inner ring of the rotating platform and extends into the telescopic groove. A connecting top plate is fixedly installed on the top end of the support screw. The connecting top plate is fixedly connected to the non-removable aluminum alloy side template. The outer surface of the lower end of the support screw is vertically provided with a limiting guide groove, and a threaded sleeve is installed through the outer wall of the support sleeve. A limiting locking bolt is rotatably installed inside the threaded sleeve, and the inner end of the limiting locking bolt is slidably engaged in the limiting guide groove.

[0015] A post-pouring strip waterproofing construction process, the specific steps of which are as follows: The location and dimensions of the post-pouring strip area were measured and planned at the construction site. A pair of non-removable aluminum alloy side formworks are fixedly installed on both sides of the post-pouring strip area using lifting and adjusting support columns, and the non-removable aluminum alloy side formworks are raised and lowered using lifting and adjusting support columns to ensure that the pair of non-removable aluminum alloy side formworks are installed flat and aligned. A steel reinforcement mesh structure is laid as a whole in the area where the concrete is poured first and the area where the concrete is poured later. The steel reinforcement in the steel reinforcement mesh structure that passes through the area where the concrete is poured later passes through the aluminum alloy side formwork that does not need to be removed. Pre-cast concrete is poured on both sides of the post-cast strip area, and the sealing waterstop strip is pressed tightly against the side of the pre-cast concrete to form the first waterproof structure. The aluminum alloy cover plate is overlapped on the top of a pair of non-removable aluminum alloy side templates, and the aluminum alloy cover plate is initially limited by the sliding engagement of the clip and the slot. Then, sealant is injected into the slot through the glue injection channel. The sealant cures to form a continuous elastic sealing strip and constitutes the second waterproof structure. After the pre-cast concrete on both sides has cured, micro-expansion impermeable concrete is poured into the post-cast strip area through the concrete pouring port on the aluminum alloy cover plate, and a vibrator is inserted through the concrete pouring port to assist in compaction, thus completing the pouring of concrete in the post-cast strip area.

[0016] The present invention has the following beneficial effects: 1. In this invention, formwork is supported by non-removable aluminum alloy side formwork. The non-removable aluminum alloy side formwork has high rigidity and is positioned by both lifting and adjusting support columns and rebar grooves, thereby improving the support strength of the formwork on both sides of the post-pouring strip area and making it less prone to formwork displacement. At the same time, the non-removable aluminum alloy side formwork adopts an integral non-mesh design, which is not easy to leak grout. This not only helps to improve the pouring effect of the first-poured concrete, but also prevents concrete grout from seeping into the post-pouring strip area, so as to facilitate the subsequent pouring of concrete in the post-pouring strip area.

[0017] 2. In this invention, a sealing waterstop strip is pre-installed in the groove on the side of the aluminum alloy side formwork facing the first-poured concrete. When the first-poured concrete is poured, the sealing waterstop strip is compacted and tightly attached between the aluminum alloy side formwork and the first-poured concrete, eliminating the hidden dangers of easy displacement and premature expansion failure of the sealing waterstop strip after installation, and improving the sealing and waterstop effect at the joint between the old and new concrete.

[0018] 3. In this invention, an aluminum alloy cover plate is installed on the top surface of a pair of non-removable aluminum alloy side formworks through a slot and a block. Simultaneously, sealant can be injected into the slot through an injection channel, forming a cured sealing layer at the joint between the aluminum alloy cover plate and the non-removable aluminum alloy side formwork. This not only improves the firmness of the connection between the non-removable aluminum alloy side formwork and the aluminum alloy cover plate, but also forms a second flexible waterproof structure at the joint. Combined with the sealing waterstop strip, this forms a double waterproof system, further improving the sealing and water-stopping effect at the joint between new and old concrete, preventing leakage. Furthermore, the aluminum alloy cover plate can protect the post-pouring strip area during the curing period of the first-poured concrete. This not only prevents rainwater from entering the post-pouring strip area and causing corrosion of the internal steel reinforcement, but also prevents impurities from entering the post-pouring strip area, eliminating the need for debris cleaning during subsequent pouring and improving the construction efficiency of the post-pouring strip area.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1 Please see Figures 1-3 , Figure 10 As shown, this embodiment is an integrated aluminum formwork waterproof structure for post-pouring strips, including a pair of non-removable aluminum alloy side formworks 1, multiple lifting and adjustable support columns 2 and aluminum alloy cover plates 3. The pair of non-removable aluminum alloy side formworks 1 are longitudinally arranged on both sides along the post-pouring strip area 200. The side of the non-removable aluminum alloy side formwork 1 facing the post-pouring strip area 200 is provided with stiffening ribs. The side of the non-removable aluminum alloy side formwork 1 facing the first-poured concrete 100 is provided with sealing water-stop strips 14. The non-removable aluminum alloy side formwork 1 is provided with through grooves 17 for the steel bars in the steel bar support mesh to pass through. The top surface of the non-removable aluminum alloy side formwork 1 is provided with slots 11. Multiple adjustable support columns 2 are horizontally distributed and installed on the side of the non-removable aluminum alloy side formwork 1 facing the post-pouring strip area 200, for supporting and positioning the non-removable aluminum alloy side formwork 1, and each adjustable support column 2 can be adjusted in height. The width of the aluminum alloy cover plate 3 is greater than the width of the post-pouring strip area 200. The bottom surfaces on both sides of the aluminum alloy cover plate 3 are provided with locking blocks 32 that respectively engage with the top surface slots 11 of a pair of non-removable aluminum alloy side templates 1. The locking blocks 32 and the slots 11 are fitted with a clearance. The aluminum alloy cover plate 3 and the locking blocks 32 are provided with glue injection channels that can communicate with the slots 11. The glue injection channels can inject sealant into the slots 11 to form a cured sealing layer in the slots 11. The aluminum alloy cover plate 3 is also provided with a concrete pouring port 36 that can communicate with the post-pouring strip area 200. The post-pouring strip area 200 is filled with micro-expansion anti-seepage concrete poured through the concrete pouring port 36.

[0026] When pouring concrete, firstly, the location and dimensions of the post-pouring strip area 200 are measured and planned at the construction site; then, a pair of non-removable aluminum alloy side formwork 1s are fixedly installed on both sides of the post-pouring strip area 200 using the lifting and adjusting support columns 2, and the non-removable aluminum alloy side formwork 1s are adjusted by lifting and adjusting the support columns 2 to ensure that the pair of non-removable aluminum alloy side formwork 1s are installed flat and aligned; next, a steel reinforcement mesh structure is laid as a whole in the area where the pre-pouring concrete 100 is located and the post-pouring strip area 200, and the steel reinforcement passing through the post-pouring strip area 200 in the steel reinforcement mesh structure passes through the non-removable aluminum alloy side formwork 1s through the through groove 17; the pre-pouring concrete 100 is poured on both sides of the post-pouring strip area 200. 0. The sealing waterstop strip 14 is pressed tightly against the side of the first-poured concrete 100 to form the first waterproof structure. The aluminum alloy cover plate 3 is overlapped on the top of a pair of non-removable aluminum alloy side templates 1, and the aluminum alloy cover plate 3 is initially limited by the sliding engagement of the clip 32 and the slot 11. Then, sealant is injected into the slot 11 through the glue injection channel. The sealant cures to form a continuous elastic sealing strip and constitutes the second waterproof structure. After the first-poured concrete 100 on both sides is cured, micro-expansion anti-seepage concrete is poured into the post-pouring strip area 200 through the concrete pouring port 36 on the aluminum alloy cover plate 3. The vibrator is inserted through the concrete pouring port 36 to assist in compaction. The concrete pouring in the post-pouring strip area 200 is then completed.

[0027] Among them, the formwork is supported by the non-removable aluminum alloy side formwork 1. The non-removable aluminum alloy side formwork 1 has high rigidity and is doubly positioned by the lifting and adjusting support column 2 and the through groove 17, thereby improving the support strength of the formwork on both sides of the post-pouring strip area and making it less prone to formwork displacement. At the same time, the non-removable aluminum alloy side formwork 1 adopts an integral non-mesh design, which is not easy to leak grout. This not only helps to improve the pouring effect of the first-poured concrete, but also prevents concrete grout from seeping into the post-pouring strip area, so as to facilitate the subsequent pouring of concrete in the post-pouring strip area. Moreover, when the first-poured concrete 100 is poured, the sealing waterstop 14 is compacted and tightly attached to the non-removable aluminum alloy side formwork 17. The removal of the aluminum alloy side formwork 1 and the pre-poured concrete 100 eliminates the potential for displacement and premature expansion failure of the sealing waterstop strip 14 after installation, thus improving the sealing and water-stopping effect at the joint between the old and new concrete. The aluminum alloy cover plate 3, fixed by injection, forms a second sealing and water-stopping structure at the joint between the old and new concrete, further improving the sealing and water-stopping effect at the joint. At the same time, the aluminum alloy cover plate 3 can also protect the post-pouring strip area 200 during the curing period of the pre-poured concrete 100, preventing rainwater and impurities from entering the post-pouring strip area 200, so as to facilitate the subsequent pouring of concrete in the post-pouring strip area 200.

[0028] Example 2 Please see Figure 1 , Figure 10 As shown, the difference between this embodiment and the above embodiment is that the stiffening ribs include transverse stiffening ribs 16 and multiple vertical stiffening ribs 15. The transverse stiffening ribs 16 are horizontally arranged on the side of the non-removable aluminum alloy side template 1, and the vertical stiffening ribs 15 are vertically arranged on the side of the non-removable aluminum alloy side template 1. The multiple vertical stiffening ribs 15 are equidistantly distributed along the transverse stiffening ribs 16. The support stiffness of the aluminum alloy side formwork 1 can be improved by setting a transverse stiffening rib 16 and multiple vertical stiffening ribs 15 on the side of the aluminum alloy side formwork 1 facing the post-pouring strip area 200. This prevents the aluminum alloy side formwork 1 from bending and deforming towards the post-pouring strip area 200 under the pressure of the pre-pouring concrete 100. At the same time, the transverse stiffening ribs 16 and vertical stiffening ribs 15 can form a rough surface on the aluminum alloy side formwork 1 to improve the bonding strength between the aluminum alloy side formwork 1 and the concrete poured in the post-pouring strip area 200.

[0029] Example 3 Please see Figures 1-9As shown, the difference between this embodiment and the above embodiment is that the glue injection channel includes a glue injection hole 31 and a guide groove 33. The guide groove 33 is disposed inside the block 32 along the length direction of the block 32. The glue injection hole 31 is disposed inside the aluminum alloy cover plate 3, and one end of the glue injection hole 31 is connected to the guide groove 33, while the other end of the glue injection hole 31 extends to the surface of the aluminum alloy cover plate 3. Multiple guide holes 34 distributed along the guide groove 33 are provided on both sides of the block 32. One end of the guide hole 34 is connected to the guide groove 33, and the other end of the guide hole 34 can be connected to the slot 11.

[0030] During glue injection, the nozzle of the glue gun is inserted into the glue injection hole 31. The glue gun then injects glue through the glue injection hole 31. Under the injection pressure, the glue can be delivered through the glue injection hole 31 to the guide channel 33 and distributed along the guide channel 33. Then, it is delivered to the card slot 11 through multiple guide holes 34 on both sides of the guide channel 33. As glue is continuously injected, the glue fills the card slot 11 and penetrates into the joint between the card block 32 and the non-removable aluminum alloy side template 1. After the glue solidifies, it can form a flexible sealing and waterproof structure at the joint between the card block 32 and the non-removable aluminum alloy side template 1, preventing mutual seepage between the first-poured concrete 100 and the post-poured strip area 200, thereby improving the sealing and waterproofing effect at the joint.

[0031] Furthermore, the upper end of the non-removable aluminum alloy side formwork 1 facing the pre-cast concrete 100 is provided with multiple glue outlet holes 12 equidistantly distributed along the slot 11. One end of the glue outlet hole 12 is connected to the slot 11, and the other end of the glue outlet hole 12 is connected to the pouring gap between the non-removable aluminum alloy side formwork 1 and the pre-cast concrete 100. This allows the sealant injected into the slot 11 to be delivered and filled into the pouring gap between the non-removable aluminum alloy side formwork 1 and the pre-cast concrete 100 along the glue outlet hole 12. This forms a flexible sealing structure in the pouring gap between the non-removable aluminum alloy side formwork 1 and the pre-cast concrete 100. This flexible sealing structure can cooperate with the sealing waterstop strip 14 to form a double sealing waterstop structure in the pouring gap between the non-removable aluminum alloy side formwork 1 and the pre-cast concrete 100, thereby further improving the sealing and waterproofing performance between the non-removable aluminum alloy side formwork 1 and the pre-cast concrete 100.

[0032] Furthermore, a pressure check valve 13 is installed inside the glue outlet 12, with the conveying direction facing the pre-poured concrete 100. The pressure check valve 13 can seal the glue outlet 12 to prevent the pre-poured concrete 100 from seeping back into the slot 11 along the glue outlet 12 during pouring. The pressure check valve 13 can also be automatically opened under the hydraulic drive of the sealant in the slot 11, so that the sealant in the slot 11 can be squeezed and delivered by the pressure check valve 13 to the pouring gap between the non-removable aluminum alloy side formwork 1 and the pre-poured concrete 100. The pressure check valve 13 is made of elastic rubber material. The side of the pressure check valve 13 facing the slot 11 is open, and the side facing the pre-cast concrete 100 is flat. The flat opening is initially sealed so that the sealant will not be transported outward through the pressure check valve 13 in the initial stage of injecting sealant into the slot 11. Instead, the sealant is continuously injected into the slot 11 to improve the uniformity and fullness of the sealant filling in the slot 11 until the slot 11 is filled with sealant. As the sealant is continuously delivered into the slot 11, the hydraulic pressure of the sealant in the slot 11 gradually increases. At this time, the sealant can open the flat opening of the pressure check valve 13 through the hydraulic pressure, thereby opening the pressure check valve 13. Then, the sealant is delivered into the pouring gap between the non-removable aluminum alloy side formwork 1 and the pre-cast concrete 100 through the pressure check valve 13.

[0033] Furthermore, the top surface of the aluminum alloy cover plate 3 is provided with multiple concrete pouring ports 36 evenly distributed, and each concrete pouring port 36 is equipped with a sealing cover 35. During the curing of the first poured concrete 100, the concrete pouring port 36 is sealed by the sealing cover 35 to prevent external moisture and debris from entering the post-pouring strip area 200 through the concrete pouring port 36. When the curing of the first poured concrete 100 is completed and it is necessary to pour concrete into the post-pouring strip area 200, the sealing cover 35 is removed to open the concrete pouring port 36, and then the micro-expansion impermeable concrete can be transported and poured into the post-pouring strip area 200 through the concrete pouring port 36. The spacing between adjacent concrete pouring ports 36 is 0.8m. At the same time, the diameter of the concrete pouring port 36 is larger than the diameter of the vibrator, so that the vibrator can be inserted into the post-pouring strip area 200 through the concrete pouring port 36 to vibrate the poured micro-expansion anti-permeability concrete, thereby improving the fullness of the micro-expansion anti-permeability concrete poured in the post-pouring strip area 200.

[0034] Example 4 Please see Figure 1 , Figures 10-13 As shown, the difference between this embodiment and the above embodiment is that the lifting and adjusting support column 2 includes a support sleeve 21, a base 22 is fixedly installed on the bottom surface of the support sleeve 21, the base 22 can be anchored to the top surface of the lower support base, a lifting support component is installed on the top of the support sleeve 21, the top of the lifting support component is fixedly connected to the non-removable aluminum alloy side template 1, and the lifting support component can be adjusted up and down along the support sleeve 21 so that the lifting support component can adjust the non-removable aluminum alloy side template 1 up and down.

[0035] The supporting base is either a foundation or a building structure. When installing the non-removable aluminum alloy side formwork 1, the lifting and adjusting support columns 2 are first fixedly installed on the supporting base below through the base 22. The initial positioning and installation of the non-removable aluminum alloy side formwork 1 is completed through the cooperation of multiple lifting and adjusting support columns 2. After both pairs of non-removable aluminum alloy side formwork 1 are installed, the level of the non-removable aluminum alloy side formwork 1 is tested with a level. Based on the test results, the lifting support components in the corresponding lifting and adjusting support columns 2 are adjusted to allow the lifting support components to adjust the level of the non-removable aluminum alloy side formwork 1, thereby fine-tuning the level of the non-removable aluminum alloy side formwork 1 and improving the level of the installation of the pair of non-removable aluminum alloy side formwork 1.

[0036] Furthermore, the bottom surface of the non-removable aluminum alloy side formwork 1 is equipped with a flexible sealing strip, which can improve the sealing performance between the bottom surface of the non-removable aluminum alloy side formwork 1 and the supporting base below, and prevent grout leakage into the interior when the pre-poured concrete 100 is poured.

[0037] Furthermore, multiple reinforcing plates arranged in a circular pattern are fixedly installed between the bottom end of the support sleeve 21 and the base 22. The base 22 is provided with positioning holes 26. When the lifting and adjusting support column 2 is installed, the base 22 is placed flat on the support base below, and then the anchor bolts are inserted through the positioning holes 26 on the base 22 and anchored in the support base below, thereby anchoring the base 22 to the top surface of the support base through the anchor bolts. The support sleeve 21 has an internal telescopic groove, and the top of the telescopic groove has a rotary table mounting groove 29; the lifting support includes a rotary table 211, which is rotatably assembled in the rotary table mounting groove 29. A nut 23 is fixedly installed on the top surface of the rotary table 211. A support screw 24 is rotatably installed on the inner ring of the nut 23 through an internal thread. The bottom end of the support screw 24 passes through the inner ring of the rotary table 211 and extends into the telescopic groove. A connecting top plate 25 is fixedly installed on the top of the support screw 24. The connecting top plate 25 is fixedly connected to the non-removable aluminum alloy side template 1. The connecting top plate 25 is supported or hinged to the transverse stiffening rib 16 on the side of the non-removable aluminum alloy side template 1, so that the supporting screw 24 supports and positions the non-removable aluminum alloy side template 1 through the connecting top plate 25 and the transverse stiffening rib 16. When the level of the non-removable aluminum alloy side template 1 is finely adjusted, the nut 23 is rotated, and the nut 23 drives the supporting screw 24 to move up and down through the thread transmission. When the supporting screw 24 moves upward, the supporting screw 24 pushes the transverse stiffening rib 16 and the non-removable aluminum alloy side template 1 upward through the connecting top plate 25. Correspondingly, when the supporting screw 24 moves downward, the supporting screw 24 drives the transverse stiffening rib 16 and the non-removable aluminum alloy side template 1 downward through the connecting top plate 25.

[0038] Furthermore, a limiting guide groove 210 is vertically provided on the outer surface of the lower end of the support screw 24, and a threaded sleeve 27 is installed through the outer wall of the support sleeve 21. A limiting locking bolt 28 is rotatably installed inside the threaded sleeve 27, and the inner end of the limiting locking bolt 28 is slidably engaged in the limiting guide groove 210. The sliding engagement between the end of the limiting locking bolt 28 and the limiting guide groove 210 can limit the support screw 24, allowing the support screw 24 to move up and down, preventing the support screw 24 from rotating with the nut 23. At the same time, after the adjustment and installation of the non-removable aluminum alloy side template 1 is completed, the limiting locking bolt 28 can be tightened, so that the limiting locking bolt 28 abuts and locks the support screw 24 in the support sleeve 21, thereby improving the stability of the support screw 24 installed in the support sleeve 21, and thus improving the stability of the support screw 24 in supporting and positioning the non-removable aluminum alloy side template 1.

[0039] Example 5 This embodiment discloses a waterproofing construction process for post-pouring strips, the specific steps of which are as follows: The location and dimensions of the 200mm post-pouring strip area were measured and planned at the construction site. A pair of non-removable aluminum alloy side templates 1 are fixedly installed on both sides of the post-pouring strip area 200 by means of lifting and adjusting support columns 2, and the non-removable aluminum alloy side templates 1 are adjusted by lifting and adjusting support columns 2 to make the pair of non-removable aluminum alloy side templates 1 flat and aligned. A steel reinforcement mesh structure is laid as a whole in the area where the pre-cast concrete 100 is located and the post-cast strip area 200, and the steel reinforcement passing through the post-cast strip area 200 in the steel reinforcement mesh structure passes through the through groove 17 and passes through the non-removable aluminum alloy side formwork 1. In the post-pouring strip area 200, pre-pouring concrete 100 is poured on both sides, and the sealing waterstop strip 14 is pressed tightly against the side of the pre-pouring concrete 100 to form the first waterproof structure. The aluminum alloy cover plate 3 is overlapped on the top of a pair of non-removable aluminum alloy side templates 1, and the aluminum alloy cover plate 3 is initially limited by the sliding engagement of the clip 32 and the slot 11. Then, sealant is injected into the slot 11 through the glue injection channel. The sealant cures to form a continuous elastic sealing strip and constitutes the second waterproof structure. After the first 100mm of concrete on both sides has been cured, micro-expansion anti-seepage concrete is poured into the post-pouring strip area 200 through the concrete pouring port 36 on the aluminum alloy cover plate 3. A vibrator is then inserted through the concrete pouring port 36 to assist in compaction, thus completing the pouring of concrete in the post-pouring strip area 200.
