Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a fixed wall panel device for building construction and its installation method. Background Technology

[0002] In building construction, the construction of cast-in-place concrete walls usually requires the use of fixed wall panel devices to position, support and fix the formwork to ensure that the formwork remains stable during the concrete pouring process, avoid displacement and deformation, and thus ensure the dimensional accuracy and forming quality of the wall.

[0003] For example, Chinese invention patent CN114934671B, entitled "A wall panel fixing device for house construction and pouring and its installation method", discloses a wall panel fixing device that uses a fixed base, connecting rod, support rod, insert plate slot and cross connector for quick installation. It also sets up a splicing structure and a sealing structure, which improves the installation efficiency, disassembly convenience and fit between the fixed base and the wall panel. To a certain extent, it solves the problems of inconvenient positioning, installation and disassembly of traditional wall panel fixing devices.

[0004] However, the aforementioned fixing method is essentially a one-time rigid locking structure. That is, after the template is installed, the positions of the connecting parts remain basically fixed. It lacks continuous compensation capability throughout the concrete pouring process. As the concrete is continuously poured, the template is subjected to gradually increasing lateral pressure, which can cause slight bulging, elastic deformation, or force shift. This changes the fit between the support plate and the template. When the template shifts, the original fixing structure cannot actively compensate for the support stroke, which can easily lead to a decrease in support pressure, the formation of gaps in some areas, and uneven stress on the template. In severe cases, it may even cause template bulging, local shifting, or deviation in wall forming dimensions. At the same time, since the support end usually adopts a fixed contact method, when the template surface tilts or deforms locally, the support surface cannot always maintain a full fit, further reducing the overall support stability.

[0005] Therefore, how to automatically compensate for the support stroke and maintain a stable clamping force even when the template undergoes slight displacement, so that the template can maintain reliable support throughout the entire pouring process, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fixed wall panel device for building construction and its installation method.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows: This invention discloses a wall panel fixing device and its installation method for building construction pouring, including a fixing base, a connecting rod, a support member and a clamping plate. The connecting rod is installed on the top of the fixing base, the support member is installed on the top of the connecting rod, and the clamping plate is disposed on one side of the support member and is used to abut against the wall template. Multiple sets of compensation components are arranged in an array along the height direction of the support member, and the compensation components are disposed between the support member and the clamping plate, which are used to provide elastic compensation support for the clamping plate when the wall formwork is subjected to the lateral pressure of concrete and causes outward deformation. The hydraulic damping component, located inside the compensation component, provides damping and buffering when the compensation component is displaced, thereby limiting the rapid movement of the compensation component. A floating component is located on the side of the compensation component near the clamping plate and is connected to both the compensation component and the clamping plate, enabling the clamping plate to float relative to the compensation component. A progressive retaining component is disposed inside the compensation component and is connected in cooperation with the compensation component. When the outward displacement of the wall template exceeds a preset range, the progressive retaining component gradually increases the moving resistance as the compensation component moves, so as to limit the further movement of the compensation component.

[0008] Furthermore, the compensation component includes: The compensation block, installed on one side of the support, is a long strip structure with an internal space for accommodating the compensation structure. The slot is formed inside the compensation block along its length. The first spring is located inside the slot, with one end of it fixedly connected to the inner wall of the slot away from the clamping plate. The movable sleeve is slidably installed inside the slot and connected to the other end of the first spring; The slide bar has one end inserted into the interior of the movable sleeve and slidably connected to the movable sleeve, and the other end passes through the outside of the compensation block and is set on one side of the clamping plate. The limiting plate is fixedly installed on the outside of the slide bar and slidably connected inside the groove to limit the movement range of the slide bar. The second spring is sleeved on the outside of the slide bar and located between the limiting plate and the movable sleeve, and is used to generate elastic compensation when the slide bar moves. The elastic stiffness of the first spring is greater than that of the second spring, so that the compensation assembly forms a phased elastic compensation support.

[0009] Furthermore, the compensation components are provided in at least three sets, which are respectively arranged in the lower region, middle region and upper region of the template. The elastic stiffness of the first spring and the second spring in the compensation components located in the lower region to the upper region of the template decreases sequentially.

[0010] Furthermore, the hydraulic damping assembly includes: The damping cylinder is fixedly installed at the end of the compensation block away from the clamping plate and is filled with hydraulic oil. A partition is installed in the middle of the inside of the damping cylinder body. The partition divides the inside of the damping cylinder body into a first oil chamber and a second oil chamber. An oil outlet hole is opened in the partition to connect the first oil chamber and the second oil chamber. The piston rod has one end slidably inserted inside the damping cylinder and the other end fixedly connected to the movable sleeve. It is used to move synchronously with the sliding of the movable sleeve to change the volume inside the first oil chamber. A reset plate is slidably disposed at the end of the damping cylinder away from the piston rod and located inside the second oil chamber. A reset spring is provided between the reset plate and the inner wall of the damping cylinder to generate elastic compression when the hydraulic oil flows from the first oil chamber into the second oil chamber, and to push the hydraulic oil in the second oil chamber back into the first oil chamber during the recovery process of the compensation component.

[0011] Furthermore, a tapered throttling needle is installed at one end of the piston rod near the reset plate, and the outer diameter of the tapered throttling needle gradually increases along the direction of insertion into the partition plate.

[0012] Furthermore, when the movable sleeve moves, it drives the piston rod to move synchronously, causing the conical throttling needle to generate axial displacement relative to the partition plate, thereby changing the flow area of ​​the damping medium and thus forming a gradual damping adjustment that changes with the compensation displacement.

[0013] Furthermore, the floating component includes: The floating seat is fixedly installed at the end of the slide bar away from the compensation block. The floating ball is rotatably installed inside the floating seat and rotatably connected to the clamping plate.

[0014] Furthermore, the end of the movable sleeve facing the first spring is configured as a tapered pushing end, and the progressive holding assembly includes: The progressive ring is fixedly installed in the middle of the groove and sleeved on the outside of the movable sleeve; Multiple sets of spring rods are arranged in an array along the circumferential direction of the progressive ring, and one end of each spring rod is slidably connected to the inside of the progressive ring. The friction contact surface is fixedly installed at one end of the spring rod facing the movable sleeve, and the side of the friction contact surface facing the movable sleeve is set as an inclined surface. The friction contact surface cooperates with the conical pushing end of the movable sleeve. The slider is slidably installed inside the progressive ring and fixedly connected to the friction contact surface, and is used to drive the friction contact surface to move in the radial direction.

[0015] Furthermore, a baffle is installed on the outer side of the progressive ring, and one end of the baffle corresponds to one end of the slider, which is used to limit the range of movement of the slider. When the slider abuts against the baffle, the spring rod reaches the compression limit.

[0016] A method for installing a wall panel fixing device for concrete pouring in building construction includes the following steps: S1. Install the fixed base on the construction foundation, and install the connecting rod on the top of the fixed base. Connect and fix the support to the connecting rod. S2. According to the installation position of the wall formwork, set the clamping plate on one side of the support, so that the clamping plate abuts against the wall formwork, and adjust the compensation component to be in the pre-compression state so that the second spring generates the initial elastic support force. S3. Install multiple sets of compensation components with corresponding elastic stiffness along the height direction of the support component, so that the compensation components at different positions can provide corresponding elastic support according to the stress conditions of different height areas of the wall formwork. S4. Adjust the floating components so that the clamping plate adjusts the angle relative to the slide bar through the floating ball, so that the clamping plate keeps in contact with the surface of the wall template. S5. During the concrete pouring process, when the wall formwork is subjected to the lateral pressure of the concrete and causes outward deformation, the sliding rod is driven to move through the clamping plate, so that the compensation component can generate elastic compensation, and the rapid movement of the compensation component is limited by the hydraulic damping component. S6. When the outward displacement of the wall formwork exceeds the set range, the movement resistance of the compensation component is gradually increased by the cooperation of the progressive holding component and the movable sleeve, so as to limit the further deformation of the wall formwork.

[0017] Compared with the prior art, the wall panel fixing device and its installation method for house construction pouring described in this invention have the following advantages: 1. This invention, by setting a compensation component between the support member and the clamping plate, utilizes the outward bulging displacement of the wall formwork caused by the lateral pressure of concrete to drive the sliding rod and movable sleeve to move accordingly. The second spring first provides elastic compensation based on minor deformation of the formwork, and after the outward bulging displacement of the formwork reaches a preset range, the first spring participates in joint compensation, thus forming a staged elastic support effect. This allows the clamping plate to maintain continuous contact with the formwork during the pouring process, improving the problem of increased support gaps caused by formwork deformation in traditional fixed support structures and enhancing the stability of the formwork support process. Furthermore, by setting multiple sets of compensation components along the height of the formwork and gradient configuring the spring stiffness within the compensation components according to the changes in lateral pressure from concrete in different height areas of the formwork, the compensation components near the lower part of the formwork can provide greater support compensation force, while the compensation components in the upper part provide adaptive elastic adjustment. This allows the support structure to match the stress state of different areas of the formwork, improving the overall stress balance of the formwork and reducing the risk of local deformation.

[0018] 2. This invention, by incorporating a hydraulic damping component, a floating component, and a progressive holding component, enables the compensation component to form an adaptive support structure with elastic compensation, buffer adjustment, and stable holding functions during operation. The hydraulic damping component is linked to the movable sleeve, allowing the piston rod and conical throttling needle to move synchronously when the movable sleeve moves. By adjusting the hydraulic oil flow resistance, the compensation component maintains a rapid response when the template experiences small deformations and enhances damping as displacement increases, reducing instability caused by rapid movement of the compensation mechanism. Furthermore, the floating component, through a floating ball, allows the clamping plate to adjust its angle according to changes in the template surface posture, improving the fit between the clamping plate and the template and ensuring more even distribution of support force. Additionally, the progressive holding component, through the cooperation of the movable sleeve and the friction contact surface, maintains elastic compensation during small deformation stages and gradually increases the movement resistance when the template bulges outward, limiting the compensation stroke. Through this structural coordination, the device can dynamically adjust according to changes in template force during casting, improving the support stability and stress adaptability of the fixed wall panel device.

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] See Figures 1-4 As shown, this invention provides a wall panel fixing device for concrete pouring in house construction, including a fixing base 1, a connecting rod 11, a support member 12, and a clamping plate 13. The connecting rod 11 is installed on the top of the fixing base 1, the support member 12 is installed on the top of the connecting rod 11, and the clamping plate 13 is disposed on one side of the support member 12 for contacting the wall formwork. Multiple sets of compensation components 2 are arranged in an array along the height direction of the support member 12 and are disposed between the support member 12 and the clamping plate 13. These components provide elastic compensation support to the clamping plate 13 when the wall formwork is subjected to lateral pressure from concrete and undergoes outward deformation. Each compensation component 2 includes a compensation block 21, installed on one side of the support member 12, which is elongated and has an internal space for accommodating the compensation structure. A slot 22 is formed along the length direction of the compensation block 21. Inside the compensation block 21; a first spring 23 is disposed inside the slot 22, with one end fixedly connected to the inner wall of the slot 22 away from the clamping plate 13; a movable sleeve 24 is slidably installed inside the slot 22 and connected to the other end of the first spring 23; a sliding rod 25 has one end extending into the movable sleeve 24 and slidably connected to the movable sleeve 24, and the other end passing through the outside of the compensation block 21 and disposed on one side of the clamping plate 13; a limiting plate 26 is fixedly installed on the outside of the sliding rod 25 and slidably connected to the slot 22, used to limit the movement range of the sliding rod 25; a second spring 27 is sleeved on the outside of the sliding rod 25 and located between the limiting plate 26 and the movable sleeve 24, used to generate an elastic compensation effect when the sliding rod 25 moves; wherein the elastic stiffness of the first spring 23 is greater than the elastic stiffness of the second spring 27.

[0023] Preferably, a preset sliding stroke is provided between the slide rod 25 and the movable sleeve 24. When the sliding rod 25 moves a distance less than the preset sliding stroke, the slide rod 25 only drives the second spring 27 to undergo elastic deformation. When the slide rod 25 moves to the end of the preset sliding stroke, the slide rod 25 and the movable sleeve 24 form axial contact and move together, causing the movable sleeve 24 to compress the first spring 23. This allows the compensation component 2 to form a phased compensation mode in which the second spring 27 first provides elastic compensation, and then the first spring 23 participates in joint compensation.

[0024] It should be noted that during the pouring process of building construction, when the wall formwork is subjected to lateral pressure generated by the internal concrete, the formwork tends to bulge outward as the pouring height increases. During initial installation, the position of the clamping plate 13 is adjusted so that the second spring 27 is in a pre-compressed state, thereby keeping the clamping plate 13 in contact with the surface of the wall formwork. At this time, the first spring 23 and the movable sleeve 24 maintain a preset distance, and the first spring 23 is in a non-compensating state. At this time, the second spring 27 stores a certain elastic potential energy, so that the clamping plate 13 always maintains the pre-tight support of the formwork. When the lateral pressure of the concrete gradually increases and causes the wall formwork to undergo slight outward bulging deformation, the formwork pushes the clamping plate 13 to produce a slight displacement away from the formwork. The clamping plate 13 drives the sliding rod 25 to move along the axial direction of the compensation block 21 to enter the compensation state.

[0025] Since the slide rod 25 extends into the movable sleeve 24 and is slidably connected to it, during the movement of the slide rod 25, it first pushes the limiting plate 26 to move synchronously, causing the second spring 27 to be gradually compressed, thereby generating an elastic support force opposite to the outward bulging direction of the template, and providing compensating support for the template.

[0026] As the outer bulge of the template increases further, the moving distance of the slide bar 25 gradually increases. When the slide bar 25 reaches the preset sliding stroke, its end forms an axial abutment with the movable sleeve 24 and pushes the movable sleeve 24 to continue moving, so that the movable sleeve 24 compresses the first spring 23. Since the elastic stiffness of the first spring 23 is greater than that of the second spring 27, the overall equivalent stiffness of the compensation component 2 is improved after the first spring 23 participates in the force.

[0027] Through the above process, in the small deformation stage, the second spring 27 participates in compensation alone to provide flexible support; in the large deformation stage, the first spring 23 and the second spring 27 work together to improve the overall support force, so that the clamping plate 13 can automatically adjust the support force according to the change of the degree of bulging of the template. Therefore, it can avoid the initial support force being too large and causing local damage to the template, and at the same time, it can provide greater resistance in the high lateral pressure stage.

[0028] Existing fixed wall panel devices typically employ a rigid connection structure. After the formwork is installed, the support position is basically fixed. When the lateral pressure of the concrete increases, causing the formwork to deform, a pressure drop between the formwork and the support structure is likely to occur. This application addresses this by setting up a compensation component 2, which uses the displacement generated by the outward bulging of the formwork to drive the sliding rod 25 to move, causing the first spring 23 and the second spring 27 to automatically generate compensation displacement, thereby keeping the clamping plate 13 always in contact with the formwork surface and avoiding support gaps caused by formwork deformation.

[0029] See Figures 1-4 As shown, the compensation component 2 has at least three sets, which are respectively arranged in the lower, middle and upper regions of the template. The elastic stiffness of the first spring 23 and the second spring 27 in the compensation component 2 located in the lower to upper regions of the template gradually decreases.

[0030] It should be noted that during the concrete pouring process, the lateral pressure on the wall formwork is not uniformly distributed, but varies with the height of the formwork. Generally, the concrete height near the bottom of the pouring area is larger, and due to the self-overlapping effect of the upper concrete, the lateral pressure generated is higher, so the lower part of the formwork experiences a stronger bulging effect. As the height increases, the lateral pressure of the concrete on the upper part of the formwork gradually decreases, and the tendency of bulging deformation is relatively smaller.

[0031] To adapt to the aforementioned stress changes, this device is equipped with at least three sets of compensation components 2 along the height direction of the support member 12, corresponding to the lower, middle and upper regions of the template, respectively.

[0032] Among them, the compensation component 2 located in the lower part of the template is equipped with a first spring 23 and a second spring 27 with large elastic stiffness; A first spring 23 and a second spring 27 with moderate elastic stiffness are provided in the compensation component 2 located in the middle area of ​​the template. A first spring 23 and a second spring 27 with relatively low elastic stiffness are installed in the compensation component 2 located in the upper region of the template.

[0033] When the formwork bulges outward due to lateral pressure during concrete pouring, the bulging displacement is more pronounced because the lower part of the formwork experiences greater lateral pressure. The high-stiffness spring in the lower compensation component 2, after being compressed, can generate a large reverse support force, which resists the outward deformation of the formwork through the clamping plate 13. The middle compensation component 2 generates corresponding elastic compensation based on the moderate lateral pressure, keeping the middle area of ​​the formwork stably supported. Since the upper part of the formwork experiences less lateral pressure, the upper compensation component 2 uses a smaller stiffness spring, which can generate appropriate elastic compensation to avoid uneven local stress on the formwork due to excessive support force.

[0034] Through the above settings, multiple compensation components 2 arranged along the height direction of the template can provide matching support forces according to the stress state of different height areas, thereby forming a gradient compensation structure that adapts to the distribution of concrete lateral pressure, reducing the risk of local deformation of the template and improving the overall stress balance of the template.

[0035] See Figures 5-6 As shown, the hydraulic damping assembly 211 is disposed inside the compensation assembly 2 and is used to provide damping and buffering effect when the compensation assembly 2 generates displacement, so as to limit the rapid movement of the compensation assembly 2. The hydraulic damping assembly 211 includes: a damping cylinder 212, which is fixedly installed at the end of the compensation block 21 away from the clamping plate 13 and is filled with hydraulic oil; a partition 213, which is installed in the middle of the interior of the damping cylinder 212, and the partition 213 divides the interior of the damping cylinder 212 into a first oil chamber and a second oil chamber. The partition 213 has an oil outlet hole inside, which is used to connect the first oil chamber and the second oil chamber, so that the hydraulic oil can pass through the oil outlet hole during the piston movement. The oil flows from one oil chamber to another second oil chamber; the piston rod 214 has one end slidably inserted inside the damping cylinder 212, and the other end is fixedly connected to the movable sleeve 24, which moves synchronously with the sliding of the movable sleeve 24 to change the volume inside the first oil chamber; the reset plate 215 is slidably disposed at the end of the damping cylinder 212 away from the piston rod 214 and located inside the second oil chamber. A reset spring 2151 is provided between the reset plate 215 and the inner wall of the damping cylinder 212, which is used to generate elastic compression when the hydraulic oil flows from the first oil chamber into the second oil chamber, and push the hydraulic oil in the second oil chamber back into the first oil chamber during the recovery process of the compensation component 2.

[0036] It should be noted that when the hydraulic damping component 211 is working, when the wall formwork is subjected to the lateral pressure of the concrete and causes outward deformation, the clamping plate 13 is pushed by the formwork and drives the movable sleeve 24 to move backward. At this time, the movable sleeve 24 synchronously drives the piston rod 214 to move along the axial direction of the damping cylinder 212.

[0037] As the piston rod 214 moves, the internal space of the first oil chamber decreases, and the hydraulic oil in the first oil chamber is squeezed and enters the second oil chamber through the oil outlet on the partition 213. When the hydraulic oil passes through the oil outlet, the oil outlet has a throttling effect on the flow of hydraulic oil, which hinders the flow of hydraulic oil and generates a hydraulic damping force opposite to the direction of movement of the piston rod 214. This reduces the moving speed of the piston rod 214 and the movable sleeve 24, prevents the clamping plate 13 from retreating rapidly when it is subjected to the bulging of the template, and improves the stability of the compensation process.

[0038] Meanwhile, as hydraulic oil enters the second oil chamber, the internal pressure of the second oil chamber increases and pushes the reset plate 215 to move, causing the reset spring 2151 to compress. When the outward bulging effect of the template weakens, under the elastic force of the reset spring 2151, the reset plate 215 pushes the hydraulic oil in the second oil chamber to flow in the opposite direction, so that the hydraulic oil returns to the first oil chamber through the oil outlet on the partition plate 213. At the same time, it drives the piston rod 214 and the movable sleeve 24 to gradually return to their initial positions, thereby realizing the cyclic operation of the hydraulic damping assembly 211.

[0039] See Figure 6 As shown, a tapered throttling needle 216 is installed at one end of the piston rod 214 near the reset plate 215. The outer diameter of the tapered throttling needle 216 gradually increases from the needle tip to the needle root, and the tapered throttling needle 216 moves from the needle tip to the needle root along the insertion direction of the partition plate 213.

[0040] In this application, a piston is fixedly installed at the inner end of the piston rod 214, and the damping cylinder 212 is divided into a first oil chamber and a second oil chamber. The first oil chamber and the second oil chamber are connected through an oil outlet hole on the partition 213. During the piston movement, hydraulic oil flows through the partition 213 to form a damping force. The conical throttling needle 216 extends into the partition 213 and changes the effective flow area so that the damping force gradually increases with the piston displacement.

[0041] It should be noted that the conical throttle needle 216 is used to adjust the hydraulic oil flow resistance according to the moving distance of the piston rod 214. When the moving distance of the piston rod 214 is small, the conical throttle needle 216 is located on the outside of the partition 213 or in a shallow insertion position. At this time, the hydraulic oil flow area is large and the damping force is small, so that the compensation component 2 can quickly respond to the small deformation of the template. As the moving distance of the piston rod 214 increases, the conical throttle needle 216 gradually penetrates into the partition 213, which reduces the hydraulic oil flow area and gradually increases the hydraulic damping, thereby buffering and limiting the large outward bulging displacement of the template. See Figures 5-6 As shown, the hydraulic damping assembly 211 and the movable sleeve 24 form a progressive damping adjustment structure that changes with the compensation displacement. When the movable sleeve 24 slides, it drives the piston rod 214 to move synchronously, causing the conical throttle needle 216 to generate axial displacement relative to the partition 213, so as to adjust the hydraulic oil flow area and make the damping force of the hydraulic damping assembly 211 gradually increase with the increase of the compensation displacement.

[0042] It should be noted that the linkage between the hydraulic damping component 211 and the movable sleeve 24 enables the outward bulging displacement of the wall template to serve as the damping adjustment input. When the template deforms to different degrees, the movable sleeve 24 generates a corresponding displacement and simultaneously changes the engagement state between the conical throttling needle 216 and the partition plate 213. This allows the hydraulic damping component 211 to automatically adjust the damping magnitude according to the degree of template bulging, achieving a progressive damping control effect of rapid compensation for small deformations and slow maintenance of large deformations, thereby improving the stability of the fixed wall panel device during the pouring process.

[0043] See Figures 4-5 As shown, the floating component 221 is disposed on the side of the compensation component 2 near the clamping plate 13 and is connected to the compensation component 2 and the clamping plate 13 respectively. It is used to enable the clamping plate 13 to float relative to the compensation component 2 to adapt to the deformation of the wall template surface. The floating component 221 includes a floating seat 222, which is fixedly installed on the end of the slide rod 25 away from the compensation block 21. The floating ball 223 is rotatably installed inside the floating seat 222 and is rotatably connected to the clamping plate 13.

[0044] It should be noted that the floating component 221 is used to achieve adaptive fitting between the clamping plate 13 and the wall formwork. Specifically, when the wall formwork is subjected to the lateral pressure of concrete and undergoes local deformation or surface tilting, the clamping plate 13 is rotatably connected to the floating seat 222 through the floating ball 223, which allows the clamping plate 13 to adjust its angle relative to the sliding rod 25. During the outward bulging of the formwork, when the clamping plate 13 is deflected due to the change in the formwork surface, the floating ball 223 rotates inside the floating seat 222, so that the contact surface of the clamping plate 13 can be automatically adjusted according to the change in the posture of the formwork surface. This avoids the point contact or edge contact problems caused by the local tilting of the formwork in traditional fixed clamping plates 13, and keeps the clamping plate 13 in effective fit with the formwork surface.

[0045] Preferably, the floating ball 223 is disposed in the ball socket of the floating seat 222 and forms an anti-detachment fit through the limiting pressure cover, so that the clamping plate 13 can make multi-directional angle adjustments around the floating ball 223, while preventing the floating ball 223 from detaching from the floating seat 222.

[0046] The above structure enables the elastic support force generated by the compensation component 2 to be evenly transmitted to the template surface along the clamping plate 13, thereby improving the stability of the template support process.

[0047] See Figure 5 , Figure 6 and Figure 7As shown, a progressive retaining component 231 is set inside the compensation component 2. One end of the movable sleeve 24 facing the progressive retaining component 231 is set as a conical pushing end and is connected to the compensation component 2. When the outward displacement of the wall template exceeds the preset range, the progressive retaining component 231 gradually increases the moving resistance as the compensation component 2 moves, so as to limit the further movement of the compensation component 2. The progressive retaining component 231 includes: a progressive ring 232, which is fixedly installed in the middle of the slot 22 and sleeved on the outside of the movable sleeve 24; and a spring rod 233, which is provided with multiple The spring rod 233 is slidably connected to the inside of the progressive ring 232. The friction contact surface 234 is fixedly installed on the end of the spring rod 233 facing the movable sleeve 24, and the side of the friction contact surface 234 facing the movable sleeve 24 is set as an inclined surface. The friction contact surface 234 cooperates with the conical pushing end of the movable sleeve 24. The slider 235 is slidably installed inside the progressive ring 232 and fixedly connected to the friction contact surface 234, and is used to drive the friction contact surface 234 to move in the radial direction.

[0048] It should be noted that when the wall formwork is subjected to a small concrete lateral pressure and only a small outward bulge deformation occurs, the moving distance of the movable sleeve 24 is small, and its conical pushing end does not fully act on the friction contact surface 234. At this time, the spring rod 233 is in the initial state, and the friction contact surface 234 and the movable sleeve 24 maintain a small contact pressure, so that the compensation component 2 can move freely and achieve elastic compensation through the first spring 23 and the second spring 27. As the wall template bulges outward, the movable sleeve 24 continues to slide towards the progressive ring 232, and its conical pushing end gradually squeezes the inclined surface of the friction contact surface 234, causing the friction contact surface 234 to move inward in the radial direction under the action of the conical surface, and driving the slider 235 to move synchronously, while compressing the spring rod 233.

[0049] As the contact pressure between the friction contact surface 234 and the movable sleeve 24 gradually increases, the moving resistance of the movable sleeve 24 gradually increases, thereby limiting the continued movement of the compensation component 2 and causing the compensation component 2 to gradually change from an elastic compensation state to a stable holding state.

[0050] See Figure 6 and Figure 7 As shown, a baffle 236 is installed on the outer side of the progressive ring 232, and one end of the baffle 236 corresponds to one end of the slider 235. The baffle 236 is used to limit the range of movement of the slider 235. When the slider 235 abuts against the baffle 236, the spring rod 233 reaches the compression limit.

[0051] It should be noted that when the movable sleeve 24 pushes the friction contact surface 234 to move continuously, the slider 235 moves along the inside of the progressive ring 232 and gradually approaches the baffle 236. When the slider 235 abuts against the baffle 236, the spring rod 233 reaches the maximum compression state. At this time, the friction contact surface 234 and the movable sleeve 24 form the maximum contact pressure, so that the progressive holding component 231 reaches the maximum holding resistance. Through the limiting effect of the baffle 236 on the slider 235, the excessive compression of the spring rod 233 can be avoided to prevent structural failure. At the same time, the maximum compensation stroke of the compensation component 2 is limited, thereby improving the operational reliability of the device.

[0052] It is worth noting that during the normal pouring of the wall formwork, the compensation component 2 first compensates for the slight outward bulging of the formwork through the elastic deformation of the first spring 23 and the second spring 27. At this time, the progressive holding component 231 is in a low resistance state, which does not affect the normal movement of the compensation component 2.

[0053] When the bulge of the template exceeds the preset compensation range, the sliding distance of the movable sleeve 24 reaches the trigger position of the progressive holding component 231, so that the conical pushing end and the friction contact surface 234 are effectively squeezed, thereby gradually increasing the moving resistance of the progressive holding component 231.

[0054] With the above settings, the compensation component 2 can automatically switch from the elastic compensation stage to the restraint holding stage according to the degree of template deformation, avoiding the compensation mechanism being in a high resistance state throughout the process and improving the compensation sensitivity.

[0055] Furthermore, the hydraulic damping component 211 and the progressive holding component 231 work together during the sliding process of the movable sleeve 24. The hydraulic damping component 211 is used to suppress the rapid displacement of the compensation component 2 when it is subjected to instantaneous changes in lateral pressure, while the progressive holding component 231 is used to limit the maximum range of movement of the compensation component 2 under the continuous outward bulging state of the template. Through the cooperation of the hydraulic damping component 211 and the progressive holding component 231, the compensation component 2 maintains a slow and stable change when subjected to dynamic impact, and maintains reliable support under long-term stress.

[0056] A method for installing a wall panel fixing device for concrete pouring in building construction includes the following steps: S1. Fix the fixed base 1 to the construction foundation, assemble the connecting rod 11 on the top of the fixed base 1, and assemble the support 12 on the upper end of the connecting rod 11.

[0057] S2. Assemble multiple sets of compensation components 2 vertically between the support member 12 and the clamping plate 13 along the support member 12. The compensation block 21 is fixed to the support member 12. The slide rod 25 is slidably assembled on the compensation block 21. The clamping plate 13 is assembled on the outer end of the slide rod 25. Adjust the position of the clamping plate 13 so that the second spring 27 is in a pre-compression state and the first spring 23 and the movable sleeve 24 maintain a preset compensation distance.

[0058] S3. The lower, middle and upper parts of the wall formwork are respectively equipped with compensation components 2 that match high, medium and low stiffness springs.

[0059] S4. The floating seat 222 is fixed to the end of the slide bar 25. The floating ball 223 is rotatably assembled on the floating seat 222 and connected to the clamping plate 13. The floating ball 223 rotates adaptively to make the clamping plate 13 fit the template.

[0060] S5. The hydraulic damping assembly 211 is installed inside the compensation block 21, the piston rod 214 is fixedly connected to the movable sleeve 24, and the conical throttling needle 216 is axially aligned with the partition plate 213.

[0061] S6. Fix the progressive ring 232 to the middle of the slot 22 and sleeve it on the outside of the movable sleeve 24, so that the conical pushing end of the movable sleeve 24 cooperates with the inclined surface of the friction contact surface 234; the slider 235 and the spring rod 233 are assembled around the progressive ring 232, and the baffle 236 is assembled on the outside of the progressive ring 232 to limit the stroke of the slider 235; during the concrete pouring process, when the wall formwork is subjected to lateral pressure and bulges outward, the formwork squeezes the clamping plate 13 and drives the sliding rod 25 to move. In the initial stage, the sliding rod 25 compresses the second spring 27, so that the second spring 27 provides elasticity. The compensation function is as follows: When the slide rod 25 moves to the preset sliding stroke, the slide rod 25 forms an axial abutment with the movable sleeve 24 and pushes the movable sleeve 24 to move, so that the movable sleeve 24 further compresses the first spring 23, and at the same time drives the piston rod 214 and the conical throttling needle 216 to move along the direction of the partition 213; when the movable sleeve 24 moves beyond the preset compensation range, its conical pushing end pushes the friction contact surface 234, so that the friction contact surface 234 moves radially and compresses the spring rod 233, thereby generating a gradually increasing holding resistance in the progressive holding assembly 231.

[0062] It should be noted that the aforementioned compensation component 2, hydraulic damping component 211, floating component 221, and progressive holding component 231 together constitute the template adaptive compensation support mechanism. The components work collaboratively through mechanical linkage. The compensation component 2 provides continuous elastic compensation support based on the displacement changes of the wall template. The hydraulic damping component 211 buffers and limits the displacement of the compensation component 2 to improve the stability of the compensation process. The floating component 221 enables the clamping plate 13 to automatically adjust its contact angle according to changes in the template surface posture, improving the contact stability of the support surface. The progressive holding component 231 gradually increases the moving resistance of the compensation component 2 after the compensation displacement reaches a preset range. To limit the excessive compensation displacement of the compensation component 2, the compensation component 2 can gradually transition from elastic compensation to stable holding when the template deforms to different degrees. The components can be connected by a connection method that enables relative movement or force transmission. Those skilled in the art can select the appropriate connection structure, guide structure, damping implementation form and installation and fixing method according to the actual construction needs to complete the implementation. Under the condition of satisfying the above functional coordination relationship, the specific structural form, size parameters, processing technology, sealing form, hydraulic medium, friction material and manufacturing method are not the limiting content of this invention. All technical solutions that use equivalent technical means to achieve the above functions should fall within the protection scope of this invention.
