Description

Technical Field

[0001] This application relates to the field of formwork for concrete wall and column casting, and in particular to a concrete wall and column anti-rotten root formwork structure and its construction process. Background Technology

[0002] Concrete walls and columns are typically constructed using cast-in-place concrete formwork. After the reinforcing steel frame is secured, the edges of the wall and column are marked with chalk lines according to the design requirements. A panel is then erected along the edges, a supporting structure is installed, and connectors are attached to form the casting formwork. Concrete mortar is then poured into the casting formwork. After the concrete mortar has hardened, the casting formwork is removed, resulting in the concrete wall and column.

[0003] When pouring concrete walls and columns on floor slabs, the floor slabs are concrete slabs, which are difficult to trim and groove. The panels also have uneven areas. After the panels are vertically installed on the floor slabs, gaps will exist between the floor slabs and the panels. When pouring concrete mortar, before the concrete mortar has solidified, the mortar will leak from the gaps, which is called concrete leakage. When the mortar leakage is serious, the ratio of water, mud and sand in the concrete mortar will be completely unbalanced, resulting in quality problems such as honeycomb, voids and exposed reinforcement in the solidified concrete, which is called concrete rot.

[0004] The main preventive measures to prevent concrete leakage are to insert long wooden wedges between the floor slab and the panel, or to pour concrete mortar outside the pouring formwork after installation to form a concrete seal to block the gap between the floor slab and the panel. After the pouring is completed and the pouring formwork is removed, the concrete seal is then removed.

[0005] In practical applications, it was found that the prevention effect of inserting long wooden wedges is poor. A gap will be formed between two adjacent panels and the floor slab. Long wooden wedges are difficult to prevent grout leakage at the gap. Concrete seals have a better prevention effect, but concrete seals consume additional building materials, and concrete seals are difficult to remove, which consumes more construction manpower, increases construction costs, and is not aesthetically pleasing after removal. Summary of the Invention

[0006] To improve the ability to prevent concrete grout leakage in an economical way, this application provides a concrete wall and column anti-rotten root formwork structure and its construction process.

[0007] Firstly, the concrete wall and column anti-rotten root formwork structure provided in this application adopts the following technical solution: A concrete wall column anti-rotten root formwork structure includes a panel and a support structure for supporting the panel. A spliced ​​sealing frame made of waste wood strips is provided at the lower end of the panel. A thermoplastic sealing assembly made of waste sleeve is detachably connected to the spliced ​​sealing frame. A fastening frame assembly is provided on the spliced ​​sealing frame. A parallel abutting component for abutting the spliced ​​sealing frame is provided on the fastening frame assembly. A vertical abutting component for abutting the spliced ​​sealing frame is provided on the support structure.

[0008] By adopting the above technical solution, after the panel and supporting structure form a casting template on the floor slab, a spliced ​​sealing frame is made from waste timber strips according to the shape of the casting template. The inner frame of the spliced ​​sealing frame can abut against the panel, and the bottom side of the spliced ​​sealing frame can abut against the floor slab. The spliced ​​sealing frame has splicing gaps, allowing the thermoplastic sealing assembly to be easily installed on it. The thermoplastic sealing assembly made from waste tubing has breaks, which can be eliminated through heat fusion bonding, allowing the thermoplastic sealing assembly to become a single unit similar in shape to the casting template. The fastening frame assembly secures the spliced ​​sealing frame, eliminating gaps at the joints. After heating the thermoplastic sealing assembly, a first thermoplastic seal is achieved. Parallel and vertical abutment components abut the spliced ​​sealing frame in two perpendicular directions. After reheating the thermoplastic sealing assembly, a second thermoplastic seal is achieved. The spliced ​​sealing frame and thermoplastic sealing assembly are recycled waste materials, while the fastening frame assembly, parallel abutment assembly, and vertical abutment assembly can be reused, economically improving the ability to prevent concrete leakage.

[0009] Optionally, the thermoplastic sealing assembly includes a ribbed thermoplastic strip disposed on the edge of the spliced ​​sealing frame. The ribbed thermoplastic strip is an open tube made by cutting a strip-shaped opening along the length of a waste PVC pipe. The ribbed thermoplastic strip abuts against the junction of the panel and the floor slab. Multiple insertion slots are provided on the spliced ​​sealing frame, and the rib thermoplastic strip is inserted into the insertion slots.

[0010] By adopting the above technical solution, the ribbed thermoplastic strip is a waste recycling of discarded PVC pipes. Through heat fusion connection, sections of open pipes can be spliced ​​into a whole ribbed thermoplastic strip. The ribbed thermoplastic strip can be easily and detachably connected to the edge of the spliced ​​sealing frame through two insertion slots, so that the ribbed thermoplastic strip abuts against the junction of the panel and the floor slab, with half of the ribbed thermoplastic strip abutting against the panel and the other half abutting against the floor slab.

[0011] Optionally, the thermoplastic sealing assembly further includes an inner thermoplastic strip disposed on the inner frame of the spliced ​​sealing frame and a side thermoplastic strip disposed on the bottom side of the spliced ​​sealing frame. The inner thermoplastic strip and the side thermoplastic strip are semi-circular tubes formed by splitting waste PVC pipes along their length. Both the inner thermoplastic strip and the side thermoplastic strip are fitted into the insertion groove, and the width of the insertion groove is adapted to the thickness of the waste PVC pipe.

[0012] By adopting the above technical solution, the inner and side thermoplastic strips are waste recycled PVC pipes. Through heat fusion connection, sections of semi-circular pipe can be spliced ​​into a complete inner or side thermoplastic strip. The inner thermoplastic strip, via two insertion slots, can be easily and detachably connected to the inner frame of the spliced ​​sealing frame, allowing it to abut against the panel. The side thermoplastic strip, via two insertion slots, can be easily and detachably connected to the bottom side of the spliced ​​sealing frame, allowing it to abut against the floor slab. The inner and side thermoplastic strips, together with the edge thermoplastic strip, form a double seal.

[0013] Optionally, the splicing sealing frame includes multiple correspondingly connected splicing strips, which are splicing strips made of waste wood strips, and there are gaps between adjacent splicing strips; A tenon is provided at one end of the splicing strip, and a mortise is provided at the end of the splicing strip away from the tenon for inserting the tenon.

[0014] By adopting the above technical solution, splicing strips are a way to reuse waste timber strips. Through the combination of tenons and mortises, splicing strips can be made into spliced ​​sealing frames of various shapes according to the shape of the casting template. The gaps between the splicing strips facilitate installation and disassembly, making it easy to install thermoplastic sealing components. Furthermore, the splicing strips can be reused.

[0015] Optionally, the fastening bracket assembly includes a fastening screw inserted into the spliced ​​sealing frame, a fastening ring sleeved on the end of the fastening screw, and a fastening nut threadedly connected to the end of the fastening screw; The spliced ​​sealing frame has a through hole for inserting the fastening screw.

[0016] By adopting the above technical solution, the fastening screw is inserted into the spliced ​​sealing frame through the through hole, and the fastening nut is rotated to tighten the spliced ​​sealing frame by the fastening ring.

[0017] Optionally, the parallel abutment assembly includes an abutment tube detachably connected to the fastening screw and a first abutment member detachably connected to the abutment tube, wherein the end of the first abutment member away from the abutment tube abuts against the outer frame of the spliced ​​sealing frame.

[0018] Optionally, a sleeve is provided at the end of the abutment pipe, the sleeve is sleeved on the fastening screw, and a fixing screw assembly for fixing the sleeve is provided on the fastening screw. The first abutting member includes a first sliding sleeve sleeved on the abutting tube, a first abutting screw disposed on the first sliding sleeve, a first abutting cylinder sleeved on the end of the first abutting screw away from the first sliding sleeve, a first abutting foot plate rotatably connected to the end of the first abutting cylinder away from the first abutting screw, and a first abutting nut threadedly connected to the end of the first abutting screw near the first abutting cylinder.

[0019] By adopting the above technical solution, the abutment pipe is fixed to the fastening screw rod through the sleeve fitting and the fixing screw assembly. The first sliding sleeve is movably sleeved on the abutment pipe. One end of the first abutment screw rod is vertically inserted into the first sliding sleeve. The first abutment cylinder is sleeved on the other end of the first abutment screw rod. The first abutment foot plate is universally hinged to the end of the first abutment cylinder sleeve away from the first abutment screw rod. Rotating the first abutment nut abuts against the first abutment cylinder, which enables the first abutment foot plate to abut against and fasten the spliced ​​sealing frame. At the same time, after heating the thermoplastic sealing component to soften it, thermoplastic sealing can be performed, improving the ability to prevent concrete leakage.

[0020] Optionally, the fixing screw assembly includes at least two adapter nuts, which are respectively disposed on both sides of the sleeve.

[0021] By adopting the above technical solution, the adapter nut can restrict the sleeve fitting, and the fixing position of the sleeve fitting can be easily adjusted by the fixing screw assembly.

[0022] Optionally, the support structure includes a secondary rib tube, and the vertical abutment assembly includes a second sliding sleeve sleeved on the secondary rib tube, a second abutment screw disposed on the second sliding sleeve, a second abutment cylinder sleeved on the end of the second abutment screw away from the second sliding sleeve, a second abutment foot plate rotatably connected to the end of the second abutment cylinder away from the second abutment screw, and a second abutment nut threadedly connected to the end of the second abutment screw near the second abutment cylinder.

[0023] By adopting the above technical solution, the vertical abutting component has a similar structure to the first abutting component. It is movably sleeved on the secondary tube via a second sliding sleeve. One end of the second abutting screw is vertically inserted into the second sliding sleeve, and the second abutting cylinder is sleeved on the other end of the second abutting screw. The second abutting foot plate is universally hinged to the end of the second abutting cylinder sleeve away from the second abutting screw. Rotating the second abutting nut abuts against the second abutting cylinder, which allows the second abutting foot plate to abut and tighten the spliced ​​sealing frame in another direction. At the same time, after heating the thermoplastic sealing component to soften it, it can perform thermoplastic sealing, thereby improving the ability to prevent concrete grout leakage.

[0024] Secondly, this application provides a construction process for a concrete wall and column anti-rotten root formwork structure, which adopts the following technical solution: A construction process for a concrete wall and column anti-rotten root formwork structure includes the following steps: Erecting the casting formwork: After drawing the outline of the wall column, set up the panel on the outside of the outline, and build the casting formwork by means of the supporting structure and connectors; Overall splicing: The splicing strips are spliced ​​into a splicing sealing frame. The inner thermoplastic strip, side thermoplastic strip and edge thermoplastic strip are fixed to the splicing sealing frame through the corresponding insertion slots. The inner thermoplastic strip, edge thermoplastic strip and edge line are left with a gap for the installation panel. The inner thermoplastic strip, side thermoplastic strip and edge thermoplastic strip are connected by heat fusion to make each of them a whole. Install vertical abutment components: Multiple vertical abutment components are fitted onto the secondary ribs of the support structure near the floor slab via the second sliding sleeve, and the second abutment foot plate abuts against the top side of the spliced ​​sealing frame. Install the fastening bracket assembly: Insert the fastening screw into the through hole of the rod, and fix the fastening screw to the spliced ​​sealing frame by fastening ring and fastening nut. Multiple fastening screws are fixed on the spliced ​​sealing frame to form a fastening bracket assembly. Install parallel abutment components: Fix the sleeve to the fastening screw by fixing the screw group, insert the abutment tube into the sleeve, and fit multiple parallel abutment components onto the abutment tube by the first sliding sleeve. The first abutment foot plate abuts against the outer frame of the spliced ​​sealing frame. Multiple thermoplastic sealing processes: The inner, side, and ridge thermoplastic strips are initially heated to soften them. The tightening nuts are then rotated to secure the spliced ​​sealing frame via the tightening rings, reducing gaps between the splicing strips. The inner, side, and ridge thermoplastic strips are then heated a second time. The first abutting nut is rotated to abut the first abutting foot against the outer frame of the spliced ​​sealing frame. The second abutting nut is rotated to abut the second abutting foot against the top side of the spliced ​​sealing frame. After the inner thermoplastic strip softens, it seals the gap between the spliced ​​sealing frame and the panel. After the side thermoplastic strip softens, it seals the gap between the spliced ​​sealing frame and the floor slab. After the ridge thermoplastic strip softens, it seals the gap between the panel and the floor slab, forming a double seal.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a spliced ​​sealing frame, thermoplastic sealing components, fastening frame components, parallel abutment components, and vertical abutment components, after the panel and supporting structure form a casting template on the floor slab, the spliced ​​sealing frame is made from waste timber strips according to the shape of the casting template. The inner frame of the spliced ​​sealing frame can abut against the panel, and the bottom side of the spliced ​​sealing frame can abut against the floor slab. The spliced ​​sealing frame has splicing gaps, allowing the thermoplastic sealing components to be easily installed on it. The thermoplastic sealing components made from waste tubing have breaks, which can be eliminated through heat fusion bonding, allowing the thermoplastic sealing components to become a single unit similar in shape to the casting template. The fastening frame assembly can be used to fasten the spliced ​​sealing frame and eliminate the splicing gaps. After heating the thermoplastic sealing assembly, a first thermoplastic seal can be performed. The spliced ​​sealing frame is abutted in two perpendicular directions by the parallel and vertical abutting components. After heating the thermoplastic sealing assembly again, a second thermoplastic seal can be performed. The spliced ​​sealing frame and thermoplastic sealing assembly are recycled waste materials. The fastening frame assembly, parallel abutting components and vertical abutting components can be reused, which can economically and effectively improve the ability to prevent concrete leakage. 2. By setting splicing strips, inserting slots, tenons and mortises, splicing strips are a way to reuse waste timber strips. Through the cooperation of tenons and mortises, splicing strips can be made into splicing sealing frames of various shapes according to the shape of the casting template. The gaps between splicing strips facilitate installation and disassembly. Inserting slots facilitate the installation of thermoplastic sealing components, and splicing strips can be reused. 3. By setting up a connecting pipe, a first abutting member, a first sliding sleeve, a first abutting screw, a first abutting cylinder, a first abutting foot plate, a first abutting nut, and a sleeve fitting, the connecting pipe is fixed to the fastening screw through the sleeve fitting and the fixing screw assembly. The first sliding sleeve is movably sleeved on the connecting pipe. One end of the first abutting screw is vertically inserted into the first sliding sleeve. The first abutting cylinder is sleeved on the other end of the first abutting screw. The first abutting foot plate is universally hinged to the end of the first abutting cylinder sleeve away from the first abutting screw. Rotating the first abutting nut abuts against the first abutting cylinder, which enables the first abutting foot plate to abut and fasten the spliced ​​sealing frame. At the same time, after heating the thermoplastic sealing component to soften it, it can perform thermoplastic sealing, improving the ability to prevent concrete leakage. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0036] This application discloses a formwork structure for preventing root rot in concrete walls and columns. (Refer to...) Figure 1 and Figure 2 A concrete wall column anti-rotten root template structure includes a panel 1 arranged along the edge line, a support structure 2 arranged on the panel 1 for support, a spliced ​​sealing frame 3 arranged at the lower end of the panel 1, a thermoplastic sealing component 5 arranged on the spliced ​​sealing frame 3, a vertical abutment component 7 detachably connected to the support structure 2, a fastening frame component 4 arranged on the spliced ​​sealing frame 3, and a parallel abutment component 6 detachably connected to the fastening frame component 4.

[0037] Panel 1 and supporting structure 2 are fixed to the floor slab to form a casting template. The spliced ​​sealing frame 3 is set at the lower end of panel 1. The inner frame of the spliced ​​sealing frame 3 is close to panel 1, and the bottom side of the spliced ​​sealing frame 3 is close to the floor slab. Thermoplastic sealing component 5 is set on the spliced ​​sealing frame 3. The opening of thermoplastic sealing component 5 is eliminated by heat fusion connection. The spliced ​​sealing frame 3 is tightly fixed by fastening bracket component 4 to reduce the gaps on the spliced ​​sealing frame 3. Vertical abutment component 7 abuts against the top side of spliced ​​sealing frame 3, and parallel abutment component 6 abuts against the outer frame of spliced ​​sealing frame 3.

[0038] After the thermoplastic sealing component 5 softens upon heating, it applies force to the spliced ​​sealing frame 3 through the vertical abutment component 7 and the parallel abutment component 6, thereby enabling the thermoplastic sealing component 5 to better seal the area between the sealing panel 1 and the floor slab. Both the spliced ​​sealing frame 3 and the thermoplastic sealing component 5 are made from waste casting template materials. The spliced ​​sealing frame 3, the fastening frame component 4, the vertical abutment component 7, and the parallel abutment component 6 can all be reused, economically improving the ability to prevent concrete leakage.

[0039] Reference Figure 2 The splicing sealing frame 3 includes multiple splicing strips 32 connected together with corresponding edge shapes. The splicing strips 32 are rectangular strips and are made of waste template wood strips. The cross-section of the splicing strips 32 is square. The length of the splicing strips 32 is set according to the situation. While referring to the edge length, the waste template wood strips are cut along the length direction, removing the parts damaged due to long-term use, and retaining the usable parts of the waste template wood strips.

[0040] A tenon 33 is provided at one end of the splicing strip 32, and a mortise 34 is provided at the end of the splicing strip 32 away from the tenon 33. The tenon 33 is an isosceles trapezoid, and the upper bottom surface of the tenon 33 is fixed to the square end face of the splicing strip 32. The tenon 33 of one splicing strip 32 can be inserted into the mortise 34 of another splicing strip 32. The mortise 34 is opened on the square end face of the splicing strip 32 so that the two splicing strips 32 can form a straight line. The mortise 34 is opened on the side of the splicing strip 32 so that the two splicing strips 32 can form an L-shape to fit the corner of the two panels 1.

[0041] In this embodiment, the cross-section of the mortise 34 is larger than that of the tenon 33, which facilitates the splicing strips 32 to form a splicing sealing frame 3. A fine-tuning distance is left between adjacent splicing strips 32. At the same time, the splicing sealing frame 3 can be easily disassembled into splicing strips 32, and the splicing strips 32 can be reused.

[0042] Reference Figure 3 and Figure 4The thermoplastic sealing assembly 5 includes an inner thermoplastic strip 51 detachably connected to the inner frame of the spliced ​​sealing frame 3, a side thermoplastic strip 52 detachably connected to the bottom side of the spliced ​​sealing frame 3, and a ridge thermoplastic strip 53 detachably connected to the edge of the spliced ​​sealing frame 3. The ridge thermoplastic strip 53 is disposed between the inner thermoplastic strip 51 and the side thermoplastic strip 52.

[0043] The thermoplastic sealing assembly 5 is made of waste PVC pipe. The inner thermoplastic strip 51 and the side thermoplastic strip 52 are both semi-circular tubes formed by splitting the waste PVC pipe along its length. The ridge thermoplastic strip 53 is an open tube made by cutting a strip-shaped opening along the length of the waste PVC pipe. After the ends of the PVC pipe are heat-melted, two sections of PVC pipe can be seamlessly fixed together. Multiple semi-circular tubes can be seamlessly fixed together to form an inner thermoplastic strip 51 or a side thermoplastic strip 52 similar in shape to the spliced ​​sealing frame 3. Multiple open tubes can be seamlessly fixed together to form a ridge thermoplastic strip 53 similar in shape to the spliced ​​sealing frame 3. This allows for the detachable and seamless connection of the inner thermoplastic strip 51, the side thermoplastic strip 52, and the ridge thermoplastic strip 53 on the spliced ​​sealing frame 3.

[0044] Reference Figure 3 and Figure 4 Multiple insertion slots 31 are provided on the spliced ​​sealing frame 3. The width of the insertion slot 31 is equal to the thickness of the waste PVC pipe. On the same surface, the distance between two adjacent insertion slots 31 is equal to the diameter of the waste PVC pipe. Multiple inner thermoplastic strips 51 or side thermoplastic strips 52 can be provided. The number of insertion slots 31 is twice the total number of inner thermoplastic strips 51, side thermoplastic strips 52 and ridge thermoplastic strips 53.

[0045] In this embodiment, there is one inner thermoplastic strip 51 and one side thermoplastic strip 52, and six insertion slots 31 are provided. Three insertion slots 31 are provided on the inner frame of the spliced ​​sealing frame 3, and three insertion slots 31 are provided on the bottom side of the spliced ​​sealing frame 3. The inner thermoplastic strip 51 is detachably connected to the spliced ​​sealing frame 3 through two adjacent insertion slots 31 on the inner frame. The side thermoplastic strip 52 is detachably connected to the spliced ​​sealing frame 3 through two adjacent insertion slots 31 on the bottom side. The edge thermoplastic strip 53 is detachably connected to the spliced ​​sealing frame 3 through the insertion slots 31 near the edge on the inner frame and the bottom side.

[0046] The edge of the wall column is far away from the edge of the floor slab. The inner frame of the spliced ​​sealing frame 3 is close to the outer surface of the panel 1. The bottom side of the spliced ​​sealing frame 3 is close to the top surface of the floor slab, so that the inner thermoplastic strip 51 abuts against the outer surface of the panel 1, the side thermoplastic strip 52 abuts against the top surface of the floor slab, and the edge thermoplastic strip 53 abuts against the junction of the outer surface of the panel 1 and the top surface of the floor slab.

[0047] Reference Figure 5In another embodiment, there is a wall column edge line near the edge of the floor slab. The edge of the floor slab coincides with the outer surface of a panel 1. At this time, the inner frame of the spliced ​​sealing frame 3 near the edge line simultaneously abuts against the outer surface of the panel 1, the edge of the floor slab, and the junction of the two. The inner frame simultaneously has an inner thermoplastic strip 51, a side thermoplastic strip 52, and a ridge thermoplastic strip 53. The inner thermoplastic strip 51 abuts against the outer surface of the panel 1, the side thermoplastic strip 52 abuts against the edge of the floor slab, and the ridge thermoplastic strip 53 abuts against the junction of the outer surface of the panel 1 and the top surface of the floor slab.

[0048] Reference Figure 6 In another embodiment, there is a wall column edge line that coincides with the edge of the floor slab. The edge surface of the floor slab coincides with the inner surface of a panel 1. At this time, the spliced ​​sealing frame 3 is folded near the edge line. The top surface of the floor slab and its edge surface are perpendicular to each other. The parts of the spliced ​​sealing frame 3 on both are also perpendicular to each other. At the edge line, the inner frame of the spliced ​​sealing frame 3 is close to the side surface of the panel 1, and the bottom side surface of the spliced ​​sealing frame 3 is close to the edge surface of the floor slab. This causes the inner thermoplastic strip 51 to abut against the side surface of the panel 1, the side thermoplastic strip 52 to abut against the edge surface of the floor slab, and the ridge thermoplastic strip 53 to abut against the junction of the side surface of the panel 1 and the edge surface of the floor slab.

[0049] Reference Figure 2 and Figure 7 The fastening frame assembly 4 includes multiple fastening screws 41 inserted into the spliced ​​sealing frame 3, fastening rings 42 sleeved on both ends of the fastening screws 41, and fastening nuts 43 threaded to both ends of the fastening screws 41. Rotating the fastening nuts 43 causes the fastening rings 42 to abut against the spliced ​​sealing frame 3, thereby fastening the spliced ​​sealing frame 3 and improving its firmness.

[0050] The spliced ​​sealing frame 3 is provided with a through hole 35 for inserting a fastening screw 41. The spliced ​​sealing frame 3 can be divided into multiple straight segments with the corner as the node. The through hole 35 is opened on the spliced ​​sealing frame 3 along the straight segments. The through holes 35 on the mutually perpendicular straight segments are staggered.

[0051] Reference Figure 1 and Figure 7 In this embodiment, the wall column is L-shaped. When the fastening bracket assembly 4 fastens the spliced ​​sealing frame 3, the fastening screw 41 needs to pass through the panel 1. The part of the fastening screw 41 inserted between the panels 1 is fitted with a PVC pipe, so that the fastening screw 41 can be pulled out when the fastening bracket assembly 4 is removed later.

[0052] Reference Figure 4 and Figure 8The parallel abutment assembly 6 includes a sleeve 63 sleeved on the fastening screw 41, a fixing screw group 44 threaded on the fastening screw 41 for fixing the sleeve 63, an abutment tube 61 inserted on multiple sleeves 63, and a first abutment member 62 sleeved on the abutment tube 61.

[0053] The sleeve 63 is rectangular and has a sleeve hole for inserting the fastening screw 41. The sleeve 63 is fitted onto the fastening screw 41. The sleeve 63 is restricted by the fixing screw assembly 44 to prevent it from detaching from the fastening screw 41. The fixing screw assembly 44 includes at least two adapter nuts 441, which are threaded onto the fastening screw 41. The two adapter nuts 441 are respectively located on both sides of the sleeve 63. The two adapter nuts 441 can fix the sleeve 63 onto the fastening screw 41.

[0054] A sleeve hole for inserting the abutment tube 61 is provided on the sleeve fitting 63. The sleeve hole is perpendicular to the sleeve rod hole. The abutment tube 61 is vertically fixed to the fastening screw 41 through the sleeve fitting 63. Since the first abutment member 62 supports the spliced ​​sealing frame 3, the abutment tube 61 is vertically fixed to at least two fastening screws 41, which improves the firmness of the abutment tube 61.

[0055] Reference Figure 4 and Figure 8 The first abutting member 62 includes a first sliding sleeve 621 sleeved on the abutting tube 61, a first abutting screw 622 inserted on the first sliding sleeve 621, a first abutting cylinder 623 sleeved on the end of the first abutting screw 622 away from the first sliding sleeve 621, a first abutting foot plate 624 rotatably connected to the end of the first abutting cylinder 623 away from the first abutting screw 622, and a first abutting nut 625 threadedly connected to the end of the first abutting screw 622 near the first abutting cylinder 623.

[0056] A slot adapted to the first abutting screw 622 is provided on the outer wall of the first sliding sleeve 621. The first abutting screw 622 is vertically inserted into the first sliding sleeve 621 through the slot. The length of the first abutting screw 622 is set according to the situation, and the length of the first abutting screw 622 is different at different positions.

[0057] The end of the first abutting cylinder 623 away from the first abutting screw 622 is sealed. A universal ball is fixed to the sealed end of the first abutting cylinder 623. The first abutting foot plate 624 is a square plate. A hinge that matches the universal ball is provided on the first abutting foot plate 624 so that the first abutting cylinder 623 and the first abutting foot plate 624 are universally hinged. A rotary knob plate is correspondingly provided on the outer wall of the first abutting nut 625. The rotary knob plate is parallelogram-shaped.

[0058] Reference Figure 1 andFigure 7 The support structure 2 includes a wooden strip that abuts against the panel 1, a secondary rib tube 21 that abuts against the wooden strip, and tie bolts inserted into the panel 1 to fix the secondary rib tube 21. The support structure 2 is existing technology and will not be described again.

[0059] Reference Figure 4 and Figure 8 The vertical abutment assembly 7 includes a second sliding sleeve 71 sleeved on the secondary tube 21, a second abutment screw 72 inserted on the second sliding sleeve 71, a second abutment cylinder 73 sleeved on the end of the second abutment screw 72 away from the second sliding sleeve 71, a second abutment foot plate 74 rotatably connected to the end of the second abutment cylinder 73 away from the second abutment screw 72, and a second abutment nut 75 threadedly connected to the end of the second abutment screw 72 near the second abutment cylinder 73.

[0060] The second sliding sleeve 71 has a similar structure to the first sliding sleeve 621, the second abutting screw 72 has a similar structure to the first abutting screw 622, the second abutting cylinder 73 has a similar structure to the first abutting cylinder 623, the second abutting foot plate 74 has a similar structure to the first abutting foot plate 624, and the second abutting nut 75 has a similar structure to the first abutting nut 625.

[0061] The vertical abutment component 7 and the parallel abutment component 6 can abut the splicing strip 32 from two mutually perpendicular directions, making the splicing sealing frame 3 more secure. At the same time, the thermoplastic sealing component 5 has a better sealing effect after being heated and softened.

[0062] The implementation principle of a concrete wall column anti-rotten root formwork structure in this application embodiment is as follows: splicing strips 32 are made from waste timber strips, and inner thermoplastic strips 51, side thermoplastic strips 52, and edge thermoplastic strips 53 are made from waste PVC pipes. Tenons 33 and mortises 34 are fitted together. Multiple splicing strips 32 are detachably connected to form a spliced ​​sealing frame 3 according to the panel 1. The inner thermoplastic strips 51, side thermoplastic strips 52, and edge thermoplastic strips 53 are detachably connected to the spliced ​​sealing frame 3. The breaks are eliminated through heat fusion, so that the inner thermoplastic strips 51, side thermoplastic strips 52, and edge thermoplastic strips 53 each form an integral part similar in shape to the spliced ​​sealing frame 3, making the inner thermoplastic strips 51, side thermoplastic strips 52, and edge thermoplastic strips 53... The material softens upon heating, and the fastening screw 41 is inserted into the spliced ​​sealing frame 3. Rotating the fastening nut 43 causes the fastening ring 42 to abut against the splicing strip 32, tightening the spliced ​​sealing frame 3. Simultaneously, the inner thermoplastic strip 51, side thermoplastic strip 52, and ridge thermoplastic strip 53 undergo a first thermoplastic seal. Rotating the first abutting nut 625 causes the first abutting foot 624 to abut against the splicing strip 32 via the first abutting cylinder 623. Rotating the second abutting nut 75 causes the second abutting foot 74 to abut against the splicing strip 32 via the second abutting cylinder 73, resulting in a second thermoplastic seal for the inner thermoplastic strip 51, side thermoplastic strip 52, and ridge thermoplastic strip 53. This economically and effectively improves the ability to prevent concrete leakage.
