Description

Technical Field

[0001] The present application relates to the field of formwork construction, and in particular to a single-sided formwork structure for a basement. Background Art

[0002] When constructing the basement, due to the limitation of the site space, when the foundation pit is supported by pile row support, the distance between the retaining piles and the outer wall of the underground project is relatively close, and it is impossible to carry out the outer wall formwork and concrete pouring of the underground project in the traditional way, i.e., formwork foundation treatment, erection of supporting formwork and scaffolding, formwork support and steel bar binding, and then concrete pouring after acceptance. As a result, the site only has the conditions for single-sided formwork of the outer wall.

[0003] During construction, several sections of single-sided formwork are spliced ​​together, and it is ensured that the single-sided formwork is parallel to the foundation pit supporting structure. The length of the spliced ​​several sections of single-sided formwork is the length of the basement outer wall. The single-sided formwork is then fixed with screws and anchor bolts pre-embedded in the base plate, and concrete is poured between the single-sided formwork and the foundation pit supporting structure to realize the construction of the basement outer wall.

[0004] However, since the size and length of a single single-sided formwork is fixed, the length of several single-sided formworks spliced ​​together cannot accurately meet the preset length of the exterior wall. Usually, there will be some shortages that cannot be filled with the same single single-sided formwork. At this time, it is necessary to select or re-prepare single-sided formworks of corresponding sizes to fill the gaps, which causes inconvenience in operation and affects construction efficiency, so it needs to be improved. Summary of the invention

[0005] In order to improve the problem that after the fixed-size single-sided formwork is spliced, it is difficult to just meet the length of the basement outer wall, and it is necessary to select or re-prepare the corresponding size of the single-sided formwork to fill the gap, resulting in low construction efficiency, the present application provides a basement single-sided formwork structure.

[0006] The present application provides a basement single-side formwork structure that adopts the following technical solution: A basement single-side formwork structure, comprising: Tripod bracket; A mounting plate, arranged horizontally and fixed on the tripod bracket; A plurality of connecting rods are arranged on a side of the mounting plate away from the triangular bracket, the connecting rods are evenly arranged along the length direction of the mounting plate, the connecting rod at one end of the mounting plate is fixed to the mounting plate, and the connecting rod at the other end is slidably connected to the mounting plate through a connecting block, and the connecting rods at both ends of the mounting plate are connected through a telescopic film, the telescopic film is located on a side of the connecting rod away from the mounting plate, and can cover the plurality of connecting rods; An adjusting component, wherein a plurality of the connecting rods are connected via the adjusting component, and the adjusting component is used for adjusting the distance between adjacent connecting rods.

[0007] By adopting the above technical solution, when in use, the triangular bracket and the mounting plate are first fixed together, the connecting rod is placed on the mounting plate, and the telescopic membrane covers all the connecting rods, so that the side of the connecting rod away from the mounting plate is a complete plane. At this time, the triangular bracket, the mounting plate and the connecting rod form a complete single-sided formwork structure.

[0008] Then, several single-sided formwork structures are delivered to the construction site, and several sections of the single-sided formwork structures are spliced ​​together to ensure that all the telescopic membranes are in the same plane. After several sections of the single-sided formwork structures are spliced ​​together, there are still gaps or surpluses compared to the preset exterior wall length. The adjustment component is started to drive several connecting rods to move along the length direction of the mounting plate at the same time to change the distance between adjacent connecting rods, so that the telescopic membranes are synchronously expanded and contracted, so that the telescopic membrane always covers the entire connecting rod, thereby ensuring that one side of the connecting rod is always a smooth plane.

[0009] The movement of the connecting rod changes the length of a single single-sided formwork structure, so that the length of several single-sided formworks spliced ​​together just meets the length of the preset exterior wall. The length of the single-sided formwork structure can be directly adjusted without selecting or preparing a single-sided formwork structure of a new size to meet the overall length of the preset exterior wall. The operation is convenient and the construction efficiency is high. Concrete is poured on the side of the telescopic membrane away from the triangular bracket. After the pouring is completed, the single-sided formwork structure is disassembled. The setting of the telescopic membrane not only ensures the flatness of the concrete side, but also plays an isolating role to prevent the concrete from sticking, which facilitates the demoulding of the single-sided formwork structure.

[0010] Optionally, the adjustment assembly includes a plurality of adjustment members, and the plurality of adjustment members correspond to the connecting rods one by one, and the adjustment members include: An adjusting rod, the center of which is hinged on the connecting rod, and a plurality of the adjusting rods are parallel to each other; A linkage rod, wherein the linkage rod and the adjusting rod are cross-arranged, the center of the linkage rod is hinged on the connecting rod, a plurality of linkage rods are parallel to each other, the end of the linkage rod is hinged on the adjusting rod of the adjacent adjusting member, and the end of the adjusting rod is hinged on the linkage rod of the adjacent adjusting member.

[0011] By adopting the above technical solution, two adjacent connecting rods are hinged by two adjusting rods and two linkage rods to form a rhombus, and the connection between the connecting rod and the adjusting member is the two vertices of the rhombus. When one of the connecting rods moves on the mounting plate, the distance between the adjacent connecting rods changes, that is, the two opposite vertices of the rhombus approach or move away from each other, so that the other two vertices of the rhombus move in opposite directions, that is, the hinge point of the end of the adjusting rod and the end of the linkage rod moves towards or away from the center of the rhombus.

[0012] During this process, the adjusting rod and the linkage rod rotate to ensure that adjacent connecting rods are always in a connected state, and the two sides of two adjacent rhombuses share an adjusting rod and a linkage rod, so that the deformation of all rhombuses is consistent, that is, all adjusting parts rotate at the same angle, so that the same distance is adjusted between adjacent connecting rods at the same time, thereby ensuring that the spacing between adjacent connecting rods is equal. The movement of the connecting rod changes the length of the telescopic membrane, and the setting of the adjusting part ensures that the several connecting rods are always evenly distributed along the length of the telescopic membrane, that is, the telescopic membrane after the length is changed can still be evenly supported, thereby improving the stability of the single-sided formwork structure.

[0013] Optionally, one of the adjusting members is provided with a telescopic rod, and the telescopic rod comprises: A fixing sleeve, one end of which is connected to the end of the linkage rod; A fixing rod is inserted into the fixing sleeve and can move in the fixing sleeve, and one end of the fixing rod away from the fixing sleeve is connected to the end of the adjusting rod.

[0014] By adopting the above technical solution, when the connecting rod moves, the hinge point of the adjusting rod and the linkage rod moves toward the center of the rhombus, thereby driving the fixed rod to slide in the fixed sleeve, so that the length of the entire telescopic rod changes, and the fixed rod and the fixed sleeve cooperate as the diagonal line of the rhombus, playing a guiding role, making the deformation of the rhombus more stable, thereby increasing the stability of the connecting rod distance adjustment.

[0015] Optionally, a fixing bolt is passed through the fixing sleeve, the fixing bolt is threadedly connected to the fixing sleeve, and an end of the fixing bolt can abut against a side wall of the fixing rod.

[0016] By adopting the above technical solution, when the fixing rod is extended and retracted in the fixing sleeve, the distance between the connecting rods is changed until the length of the telescopic membrane meets the setting, and the fixing bolt is adjusted in the direction of the fixing rod until the end of the fixing bolt abuts against the side wall of the fixing rod. The fixing bolt applies a tightening force to the fixing rod, thereby fixing the fixing rod on the fixing sleeve, so that the length of the diagonal line of the rhombus is fixed, thereby fixing the shape of the rhombus, that is, the distance between adjacent connecting rods is fixed, so that the connecting rod cannot move, thereby realizing the positioning of the connecting rod and completing the fixation of the length of the telescopic membrane.

[0017] Optionally, a plurality of connecting plates are fixed on the side wall of the connecting rod, and the connecting plates are evenly arranged along the length direction of the connecting rod, and the connecting plates on adjacent connecting rods are staggered.

[0018] By adopting the above technical solution, a number of connecting plates are staggered and crossed to fill the space between adjacent connecting rods, so that the part of the telescopic membrane corresponding to the area between the adjacent connecting rods can also be supported, thereby increasing the stability of the telescopic membrane, overcoming the pressure exerted by the concrete on the telescopic membrane to prevent the telescopic membrane from deforming, and improving the flatness of the side wall of the cast concrete wall.

[0019] Optionally, a receiving groove is formed between adjacent connecting plates, and the connecting plate on the connecting rod can be adapted to be inserted into the receiving groove on the adjacent connecting rod. A slider is provided on the side wall of the connecting plate, and a sliding groove is provided on the inner wall of the receiving groove. The slider is inserted into the sliding groove and can move in the sliding groove.

[0020] By adopting the above technical solution, when the adjusting component drives the connecting rod to move, the connecting plate moves in the accommodating groove, the slider moves in the slide groove, the inner wall of the slide groove contacts the side wall of the slider, which plays a limiting and guiding role, so that the connecting rod will not deflect during the movement, thereby realizing the integrity of several connecting rods, thereby improving the stability of the single-sided formwork structure.

[0021] Optionally, a mounting frame is provided on the connecting rod, a water storage bag is provided on the mounting frame, a water storage bag is provided in the accommodating groove, a connecting plate is provided on the connecting plate, the connecting plate is located between the water storage bag and the water storage bag, and the ends of the water storage bag and the water storage bag that are close to each other are fixed to the connecting plate, and the water storage bag and the water storage bag are connected through the connecting hole on the connecting plate.

[0022] By adopting the above technical solution, when adjacent connecting rods move away from each other, the connecting plate is gradually pulled out of the receiving groove, so that there is a gap between the end of the connecting plate and the receiving groove, and the water storage bag is located in the receiving groove and blocks the gap.

[0023] When the connecting rod moves, one of the two adjacent connecting rods moves synchronously with the mounting frame, while the other connecting rod moves with the connecting plate away from the water storage bag. In this process, the water storage bag is squeezed by the connecting plate, deformed, and its size and capacity become smaller. The water storage bag is pulled by the connecting plate and deformed, and its size and capacity become larger, so that the water in the water storage bag enters the water storage bag through the connecting hole on the connecting plate, so that the water storage bag is filled with water and is not easy to deform, so that the empty part of the receiving groove can also support the telescopic membrane. When the concrete is poured and the concrete exerts pressure on the telescopic membrane, the side of the entire telescopic membrane away from the concrete is fully supported, which improves the compressive strength of the single-sided formwork structure and further improves the flatness of the concrete.

[0024] Optionally, the stretch film comprises: Two winding rollers are respectively inserted into the connecting rods at both ends of the mounting plate, the ends of the winding rollers are rotatably connected to the connecting rods, and the winding tubes are arranged along the length direction of the connecting rods; Two coil springs, the two coil tubes correspond to the winding rollers one by one, the coil tubes are sleeved on the corresponding winding rollers, one end of the coil spring is fixed to the winding roller, and the other end is fixed to the connecting rod; An oil film, one end of which is fixed on one of the winding rollers, and the other end of which is fixed on the other winding roller, and the oil film can be wound on a winding tube.

[0025] By adopting the above technical solution, when the connecting rods move away from each other, the oil film is pulled apart, so that the oil film is released from the winding roller, driving the winding roller to rotate, causing the coil spring to deform, and the elastic force of the coil spring always drives the winding roller to reset, so that the oil film is always in a tensioned state to fit the connecting rod, so that the oil film itself is flat. When the connecting rods move closer to each other, the oil film shrinks, the coil spring recovers its deformation, drives the winding roller to reset, and the oil film is gradually wound on the winding roller, realizing the change of the length of the oil film.

[0026] Optionally, a rubber magnet is embedded on the oil film, and the rubber magnet can be attracted to the connecting plate and the connecting rod.

[0027] By adopting the above technical solution, the rubber magnet makes the oil film tightly attached to the connecting plate and the connecting rod, making the oil film not easy to bend and deform, improving the flatness of the oil film itself, thereby improving the flatness of the concrete side after pouring.

[0028] Optionally, a roller is hinged at the bottom of the tripod bracket.

[0029] By adopting the above technical solution, when the single-sided formwork structure arrives at the construction site, the triangular bracket is directly moved so that the rollers roll on the ground, which facilitates the overall movement of the single-mode formwork structure, realizes further detailed adjustment of the position of the single-mode formwork structure, and improves the construction accuracy.

[0030] In summary, the present application includes at least one of the following beneficial effects: 1. Deliver several single-sided formwork structures to the construction site, and splice several sections of the single-sided formwork structures to ensure that all the telescopic membranes are in the same plane. When several sections of the single-sided formwork structures are spliced, there are still gaps or surpluses compared to the preset length of the exterior wall. Start the adjustment component to drive several connecting rods to move along the length direction of the mounting plate at the same time to change the distance between adjacent connecting rods, so that the telescopic membranes are synchronously expanded and contracted, so that the telescopic membranes always cover the entire connecting rod, thereby ensuring that one side of the connecting rod is always a smooth plane. The overall length of the single-sided formwork structure changes, and there is no need to select or prepare a single-sided formwork structure of a new size to meet the preset overall length of the exterior wall. The operation is convenient, and the construction efficiency is high. 2. Several connecting plates are staggered and crossed to fill the space between adjacent connecting rods, so that the part of the telescopic membrane corresponding to the area between adjacent connecting rods can also be supported, which increases the stability of the telescopic membrane. At the same time, the connecting rod drives the connecting plate to move, so that the connecting plate squeezes the water storage bag, the water storage bag is deformed, and the size and capacity become smaller. The water storage bag is pulled by the connecting plate and deformed, and the size and capacity become larger, so that the water in the water storage bag enters the water storage bag through the connecting holes on the connecting plate, so that the water storage bag is filled with water and is not easy to deform, so that the empty part of the receiving groove can also support the telescopic membrane. When pouring concrete and the concrete exerts pressure on the telescopic membrane, the side of the entire telescopic membrane away from the concrete is fully supported, which improves the compressive capacity of the single-sided formwork structure, thereby improving the flatness of the concrete.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The present application embodiment discloses a basement single-side formwork structure. Figure 1 and Figure 2 The basement single-side formwork structure includes a triangular bracket 10, and a roller 11 is hinged at the bottom of the triangular bracket 10 to facilitate the displacement of the triangular bracket 10 on the ground. Anchor bolts are embedded in the bottom plate to be constructed. When the triangular bracket 10 arrives at the construction site, the inclined plate on the triangular bracket 10 is penetrated by the anchor bolts, and is pressed and fixed by a pad to achieve the fixation of the inclined plate and the anchor bolts, thereby limiting the movement of the triangular bracket 10 and fixing the position of the triangular bracket 10.

[0035] Reference Figure 1 and Figure 2 A mounting plate 20 is fixed on one side of the triangular bracket 10 in the vertical direction. The mounting plate 20 is arranged horizontally. A plurality of connecting rods 30 are installed on the side of the mounting plate 20 away from the triangular bracket 10. The connecting rods 30 are arranged vertically and are arranged at intervals along the length direction of the mounting plate 20. The connecting rod 30 at one end of the mounting plate 20 is fixed to the mounting plate 20. A connecting block 33 is fixed on the connecting rod 30 at the other end of the mounting plate 20. The connecting block 33 is inserted from the end opening of the mounting plate 20 and can slide on the mounting plate 20 along the length direction of the mounting plate 20. When the connecting rod 30 is pulled out of the length range of the mounting plate 20, part of the connecting block 33 is still located in the mounting plate 20, so that the connecting rod 30 always maintains a connection relationship with the mounting plate 20. The side walls of the remaining connecting rods 30 are all fixed with protrusions, which are inserted into the mounting plate 20 and can slide on the mounting plate 20.

[0036] Reference Figure 2 and Figure 3, several connecting rods 30 are connected by an adjusting assembly 40, the adjusting assembly 40 includes several adjusting members 41, several adjusting members 41 correspond to the connecting rods 30 one by one, several adjusting members 41 are on the same horizontal line, the adjusting member 41 includes an adjusting rod 411 and a linkage rod 412, the adjusting rod 411 and the linkage rod 412 are cross-arranged, the intersection of the adjusting rod 411 and the linkage rod 412 is the center point of the adjusting rod 411 and the linkage rod 412, and the intersection of the adjusting rod 411 and the linkage rod 412 is hinged on the corresponding connecting rod 30.

[0037] Reference Figure 2 and Figure 3 , a plurality of adjusting rods 411 are parallel to each other, a plurality of linkage rods 412 are parallel to each other, and adjacent adjusting members 41 are connected end to end. Specifically, the end of the adjusting rod 411 is hinged on the linkage rod 412 of the adjacent adjusting member 41, and the end of the linkage rod 412 is hinged on the adjusting rod 411 of the adjacent adjusting member 41. The adjusting member 41 located on the connecting rod 30 at the end of the mounting plate 20 can be set to half, that is, only to the center of the adjusting rod 411 and the linkage rod 412, ensuring that the intersection is hinged on the connecting rod 30 at the end, so that the adjusting member 41 will not exceed the range of the single-sided formwork structure.

[0038] Concrete will be poured on the side of the connecting rod 30 away from the triangular bracket 10. In order to make the side of the connecting rod 30 away from the triangular bracket 10 always a complete plane and ensure the flatness of the concrete wall after pouring, the side wall of the connecting rod 30 is covered with a telescopic film 50, which connects the connecting rod 30 at both ends of the mounting plate 20.

[0039] Reference Figure 2 and Figure 3 The triangular bracket 10, the mounting plate 20 and the connecting rod 30 form a complete single-sided formwork structure. When several single-sided formwork structures arrive at the construction site and are spliced, ensure that all the telescopic membranes 50 are in the same plane. When several sections of single-sided formwork structures are spliced, there is still a gap or surplus compared to the preset exterior wall length. Then the connecting rod 30 at the end of the mounting plate 20 is directly installed to the appropriate position. Since two adjacent connecting rods 30 are hinged by two adjustment rods 411 and two linkage rods 412 to form a rhombus, the connection between the connecting rod 30 and the adjustment member 41 is the two vertices of the rhombus. When one of the connecting rods 30 moves on the mounting plate 20, the distance between the adjacent connecting rods 30 changes, that is, the two opposite vertices of the rhombus are close to or away from each other, so that the other two vertices of the rhombus move in opposite directions, that is, the hinge point at the end of the adjustment rod 411 and the end of the linkage rod 412 moves in the direction close to or away from the center of the rhombus.

[0040] Reference Figure 1 and Figure 2During this process, the adjusting rod 411 and the linkage rod 412 rotate to ensure that the adjacent connecting rods 30 are always in a connected state, and the two sides of the two adjacent rhombuses share an adjusting rod 411 and a linkage rod 412, so that the deformation of all rhombuses is consistent, that is, all the adjusting members 41 rotate at the same angle, so that the adjacent connecting rods 30 are adjusted to the same distance at the same time, thereby ensuring that the spacing between adjacent connecting rods 30 is equal. The movement of the connecting rods 30 causes the telescopic membrane 50 to telescope synchronously, and the setting of the adjusting member 41 ensures that the plurality of connecting rods 30 are always evenly distributed along the length of the telescopic membrane 50, that is, the telescopic membrane 50 can still be evenly supported after the length is changed, thereby improving the stability of the single-sided formwork structure.

[0041] The movement of the connecting rod 30 changes the length of a single single-sided formwork structure, so that the length of a plurality of single-sided formworks spliced ​​together just meets the length of the preset external wall. Then, concrete is poured on the side of the telescopic membrane 50 away from the triangular bracket 10. After the pouring is completed, the single-sided formwork structure is disassembled. The setting of the telescopic membrane 50 not only ensures the flatness of the concrete side, but also plays an isolating role to prevent the concrete from sticking, which facilitates the demoulding of the single-sided formwork structure.

[0042] Reference Figure 3 and Figure 4 In order to increase the stability of the movement of the connecting rod 30 and fix the connecting rod 30 after it is moved into place, a telescopic rod 60 is provided on one of the adjusting members 41. The telescopic rod 60 includes a fixing sleeve 61 and a fixing rod 62. One end of the fixing sleeve 61 is hinged to the end of the linkage rod 412. The fixing rod 62 is inserted into the fixing sleeve 61 and can move in the fixing sleeve 61. One end of the fixing rod 62 away from the fixing sleeve 61 is hinged to the end of the adjusting rod 411. A fixing bolt 63 is passed through the fixing sleeve 61. The fixing bolt 63 is threadedly connected to the fixing sleeve 61. The end of the fixing bolt 63 can abut against the side wall of the fixing rod 62.

[0043] The fixing bolt 63 is adjusted in a direction away from the fixing rod 62 so that the fixing bolt 63 is separated from the fixing rod 62, and the connecting rod 30 can be moved. The movement of the connecting rod 30 causes the hinge point of the adjusting rod 411 and the linkage rod 412 to move toward the center of the rhombus, thereby driving the fixing rod 62 to slide in the fixing sleeve 61, so that the length of the entire telescopic rod 60 changes. The fixing rod 62 and the fixing sleeve 61 cooperate as the diagonal line of the rhombus, which plays a guiding role, making the deformation of the rhombus more stable, thereby increasing the stability of the distance adjustment of the connecting rod 30.

[0044] Reference Figure 3 and Figure 4When the length of the telescopic membrane 50 meets the setting, the fixing bolt 63 is adjusted toward the fixing rod 62 until the end of the fixing bolt 63 abuts against the side wall of the fixing rod 62. The fixing bolt 63 applies a tightening force to the fixing rod 62, thereby fixing the fixing rod 62 on the fixing sleeve 61, so that the length of the diagonal line of the rhombus is fixed, thereby fixing the shape of the rhombus, that is, the distance between adjacent connecting rods 30 is fixed, so that the connecting rod 30 cannot move, thereby realizing the positioning of the connecting rod 30 and completing the fixing of the length of the telescopic membrane 50.

[0045] Reference Figure 2 and Figure 3 In order to overcome the pressure of concrete on the telescopic membrane 50 and increase the supporting force of the telescopic membrane 50, a plurality of connecting plates 31 are integrally formed on the side wall of the connecting rod 30. The connecting plates 31 are located between adjacent connecting rods 30. The plurality of connecting plates 31 are evenly arranged along the length direction of the connecting rod 30. Accommodation grooves 70 are formed between adjacent connecting plates 31. The plurality of accommodation grooves 70 on the connecting rod 30 correspond to the connecting plates 31 on the opposite connecting rod 30 one by one, and the connecting plates 31 can be inserted into the corresponding accommodation grooves 70, that is, the connecting plates 31 on adjacent connecting rods 30 are staggered. A slider is provided on the side wall of the connecting plate 31, and a slide groove is provided on the inner wall of the accommodating groove 70. The slider is inserted into the slide groove and can move in the slide groove.

[0046] A plurality of connecting plates 31 are staggered and crossed to fill the space between adjacent connecting rods 30, so that the portion of the telescopic membrane 50 corresponding to the area between the adjacent connecting rods 30 can also be supported, thereby increasing the stability of the telescopic membrane 50, being able to overcome the pressure exerted by the concrete on the telescopic membrane 50 to prevent the telescopic membrane 50 from deforming, and improving the flatness of the side wall of the cast concrete wall.

[0047] Reference Figure 2 and Figure 3 When the connecting rod 30 moves, the connecting plate 31 moves in the accommodating groove 70, and the slider moves in the slide groove. The inner wall of the slide groove contacts the side wall of the slider, which plays a limiting and guiding role, so that the connecting rod 30 will not deflect during the movement, thereby realizing the integrity of several connecting rods 30, thereby improving the stability of the single-sided formwork structure.

[0048] Reference Figure 3 and Figure 5 When the adjacent connecting rods 30 move away from each other, the connecting plate 31 is gradually pulled out of the receiving groove 70, so that there is a gap between the end of the connecting plate 31 and the receiving groove 70. In order to fill this space, a mounting frame 32 is provided on the connecting rod 30, and a water storage bag 321 is installed on the mounting frame 32. A water storage bag 80 is installed in the receiving groove 70. The water bag 321 and the water bag 80 are both water bags made of rubber material, and only a part of the area of ​​the water bag 321 is glued to the mounting frame 32, and only a part of the area of ​​the water bag 80 is glued to the inner wall of the receiving groove 70. A connecting plate 311 is fixed on the connecting plate 31, and the connecting plate 311 is located between the water bag 321 and the water bag 80, and the ends of the water bag 321 and the water bag 80 that are close to each other are fixed to the connecting plate 311, and the water bag 321 and the water bag 80 are connected through the connecting hole on the connecting plate 311.

[0049] Reference Figure 3 and Figure 5 When adjacent connecting rods 30 move away from each other, the connecting plate 31 is gradually pulled out of the receiving groove 70, so that there is a gap between the end of the connecting plate 31 and the receiving groove 70, and the water storage bag 80 is located in the receiving groove 70 and blocks the gap. When the connecting rod 30 moves, one of the two adjacent connecting rods 30 moves synchronously with the mounting frame 32, while the other connecting rod 30 moves with the connecting plate 311 in the direction away from the water storage bag 80.

[0050] During this process, the water storage bag 321 is squeezed by the connecting plate 311, and the water storage bag 321 is deformed, and its size and capacity become smaller. The water storage bag 80 is pulled by the connecting plate 311 and deformed, and its size and capacity become larger, so that the water in the water storage bag 321 enters the water storage bag 80 through the connecting hole on the connecting plate 311, so that the water storage bag 80 is filled with water and is not easy to deform, so that the empty part of the receiving groove 70 can also support the telescopic membrane 50. When pouring concrete and the concrete applies pressure to the telescopic membrane 50, the side of the entire telescopic membrane 50 away from the concrete is fully supported, thereby improving the compressive strength of the single-sided formwork structure and further improving the flatness of the concrete.

[0051] Reference Figure 1 and Figure 6 The telescopic film 50 includes an oil film 53 and two winding rollers 51. The two winding rollers 51 are respectively inserted into the connecting rods 30 at both ends of the mounting plate 20. The ends of the winding rollers 51 are rotatably connected to the connecting rods 30. The winding tubes are arranged along the length direction of the connecting rods 30. A coil spring 52 is sleeved on the winding roller 51. One end of the coil spring 52 is fixed to the winding roller 51, and the other end is fixed to the connecting rod 30.

[0052] Reference Figure 1 and Figure 6 One end of the oil film 53 is fixed on one of the winding rollers 51, and the other end is fixed on the other winding roller 51, and the oil film 53 can be wound on the winding tube. Concrete demoulding oil is attached to the oil film 53 so that the single-sided formwork structure is separated from the concrete. A rubber magnet is embedded in the oil film 53, and the rubber magnet can be attracted to the connecting plate 31 and the connecting rod 30.

[0053] When the connecting rods 30 move away from each other, the oil film 53 is pulled apart, so that the oil film 53 is released from the winding roller 51, driving the winding roller 51 to rotate, causing the coil spring 52 to deform, and the elastic force of the coil spring 52 always drives the winding roller 51 to reset, so that the oil film 53 is always in a tensioned state to fit the connecting rod 30, so that the oil film 53 itself is flat. When the connecting rods 30 move closer to each other, the oil film 53 retracts, the coil spring 52 recovers its deformation, driving the winding roller 51 to reset, so that the oil film 53 is gradually wound on the winding roller 51, and the length of the oil film 53 is changed. The rubber magnet makes the oil film 53 close to the connecting plate 31 and the connecting rod 30, so that the oil film 53 is not easy to bend and deform, and the flatness of the oil film 53 itself is improved, thereby improving the flatness of the side of the concrete after pouring.

[0054] The implementation principle of a single-sided formwork structure for a basement in an embodiment of the present application is as follows: when in use, the triangular bracket 10 and the mounting plate 20 are first fixed together, the connecting rod 30 is placed on the mounting plate 20, and the telescopic membrane 50 covers all the connecting rods 30, so that the side of the connecting rod 30 away from the mounting plate 20 is a complete plane. At this time, the triangular bracket 10, the mounting plate 20 and the connecting rod 30 form a complete single-sided formwork structure.

[0055] Then, several single-sided formwork structures are delivered to the construction site, and several sections of single-sided formwork structures are spliced ​​to ensure that all the telescopic membranes 50 are in the same plane. After several sections of single-sided formwork structures are spliced, there are still gaps or surpluses compared to the preset exterior wall length. The adjustment component 40 is started to drive several connecting rods 30 to move along the length direction of the mounting plate 20 at the same time to change the distance between adjacent connecting rods 30, so that the telescopic membrane 50 is synchronously expanded and contracted, so that the telescopic membrane 50 always covers the entire connecting rod 30, thereby ensuring that one side of the connecting rod 30 is always a smooth plane.

[0056] The movement of the connecting rod 30 changes the length of a single single-sided formwork structure, so that the length of several single-sided formworks spliced ​​together just meets the length of the preset exterior wall. The length of the single-sided formwork structure is directly adjusted without selecting or preparing a single-sided formwork structure of a new size to meet the overall length of the preset exterior wall. The operation is convenient and the construction efficiency is high. Concrete is poured on the side of the telescopic membrane 50 away from the triangular bracket 10. After the pouring is completed, the single-sided formwork structure is disassembled. The setting of the telescopic membrane 50 not only ensures the flatness of the concrete side, but also plays an isolating role to prevent the concrete from sticking, which facilitates the demoulding of the single-sided formwork structure.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
