Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of precast cover plate construction, in particular to an adjustable formwork support and fixing device for precast cover plates.
Background Art
[0002] The deformation joint concrete cover plate is a device used for deformation joints in building structures. Its main function is to ensure that the building structures on both sides of the deformation joint can deform independently, and at the same time prevent dust, water vapor and other sundries from entering the deformation joint, thereby reducing potential damage to the building.
[0003] Under the conventional construction plan, the deformation joint concrete cover plate is generally cast on-site by formwork support at the specific construction site. This plan can be adjusted and customized according to the actual situation on-site to ensure a good combination of the cover plate and the surrounding structure. In the above construction plan, wooden formwork and square timbers are generally used for installation and splicing during formwork support, and nails are used to splice the formwork during the process. However, due to the relatively thin thickness of the deformation joint concrete cover plate, conventional reinforcement cannot be carried out on the side, and the yang angles where the wooden formworks are spliced with each other are weak parts. Therefore, quality problems such as leakage of mortar, bulging of formwork, and explosion of formwork are extremely likely to occur during the concrete pouring process. In addition, due to the relatively small height of the side piers hanging down on both sides of the cover plate, it is difficult to control the dimensional accuracy using the wooden formwork hanging formwork, and it is easy to cause edge collapse, affecting the quality appearance.

Specific Embodiment
[0026] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, the following further details this application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.
[0027] This embodiment provides an adjustable formwork support and fixing device for precast cover plates, which is used to solve the problems in the prior art that the formwork support and fixing device for cover plates cannot adjust the forming thickness of the side piers of the cover plates, and the problems such as slurry leakage and formwork bulging that may occur in the case of using the cast-in-place cover plate solution. Please refer to Figures 1 to 4 An adjustable formwork support and fixing device for precast cover plates includes two positioning members 2 respectively arranged in the cover plate forming mold 1 and cooperating with the two side templates thereof to reinforce the forming of the side piers of the cover plate. An adjusting mechanism 3 for controlling the forming thickness of the side piers of the cover plate is arranged between the two positioning members 2.
[0028] In this embodiment, the positioning member 2 can be a rod-shaped or plate-shaped structure with a certain strength and stiffness, which is used to cooperate with the two side templates of the cover plate forming mold 1. The positioning member 2 provides a space for the forming of the side piers of the cover plate between it and the two side templates of the cover plate forming mold 1, and at the same time provides a lateral supporting force to ensure the forming stability of the side piers of the cover plate. The adjusting mechanism 3 is arranged between the two positioning members 2 and is used to adjust the distance between the positioning members 2, so as to control the forming thickness of the side piers of the cover plate. The adjusting mechanism 3 can include structures such as a lead screw, a nut, and a sleeve screw to adjust the distance between the positioning members 2. In addition, the adjusting mechanism 3 can also be provided with scales or marks to facilitate accurate control of the adjustment range and accuracy, and since the on-site casting of the cover plate is avoided, the problems such as slurry leakage and formwork bulging that may occur in the on-site formwork casting are naturally eliminated.
[0029] Further, as a preferred implementation manner of this solution rather than a limitation, the adjusting mechanism 3 includes two connecting members 31 respectively fixed to the two positioning members 2, and an adjusting device 32 is connected between the two connecting members 31, which can move the two connecting members 31 away from or close to each other in opposite directions, so that the device can more accurately and conveniently adjust the forming thickness of the side stack of the cover plate.
[0030] In this embodiment, the connecting member 31 can be a structure with a fixing hole, and is fixed to the positioning member 2 through fasteners such as bolts or pins, or can also be directly fixed to the positioning member 2 by welding. The adjusting device 32 is arranged between the two connecting members 31 and is used to drive the two connecting members 31 to move relative to each other, that is, move away from or close to each other in opposite directions, so that the entire device can more accurately and conveniently adjust the forming thickness of the side stack of the cover plate.
[0031] Further, as a preferred implementation manner of this solution rather than a limitation, the connecting member 31 is a screw rod threadedly connected to the adjusting device 32, and the adjusting device 32 is a threaded sleeve.
[0032] In this embodiment, the connecting member 31 is in the form of a screw rod, one end of which is fixedly connected to the positioning member 2, and the other end is threadedly connected to the adjusting device 32. The adjusting device 32 is in the form of a threaded sleeve, and its inner wall is provided with threads matching the screw rod. By rotating the threaded sleeve, the screw rod threadedly connected to it can be driven to move synchronously, thereby adjusting the distance between the positioning members 2.
[0033] The threaded connection method between the screw rod and the threaded sleeve has self-locking property, which can provide reliable connection and adjustment effect. During the adjustment process, even if affected by external force impact or vibration, the connection between the screw rod and the threaded sleeve will not loosen, ensuring the stability and reliability of the adjustment. In addition, the structures of the screw rod and the threaded sleeve are relatively simple, with low manufacturing cost, and are easy to process and assemble. At the same time, this structure also makes the maintenance of the device more convenient. When the screw rod or the threaded sleeve is worn or damaged, it can be conveniently replaced or repaired.
[0034] Further, as a preferred implementation manner of this solution rather than a limitation, the positioning member 2 is a metal square tube with the same height as the side stack of the cover plate. Since the positioning member 2 adopts a metal square tube with the same height as the side stack of the cover plate, it can accurately cooperate with the cover plate forming die 1 to provide accurate lateral positioning, ensuring the forming quality of the side stack of the cover plate. In addition, the metal square tube is preferably made of steel, which is easy to obtain at the construction site and can also be customized according to the height of the side stack of the cover plate. Therefore, this device can be applied to cover plates with different side stack heights and has strong versatility.
[0035] Further, as a preferred implementation manner of this solution rather than a limitation, a plurality of reinforcing rib plates 4 are uniformly arranged at the connection part of the positioning member 2 and the connecting member 31.
[0036] In this embodiment, the provision of the reinforcing rib plate 4 can increase the contact area and connection strength between the positioning member 2 and the connecting member 31, improve the reliability and stability of the connection. By adding the reinforcing rib plate 4, the stiffness of the entire device can be improved, enhancing its ability to resist deformation, which is crucial for ensuring the forming quality of the cover side stack, and can effectively prevent dimensional deviations of the cover side stack caused by device deformation.
[0037] Furthermore, as a preferred implementation manner rather than a limitation of this solution, the number of the reinforcing rib plates 4 is two and they are respectively arranged at the upper and lower ends of the connecting member 31. The reinforcing rib plate 4 is triangular in shape, and its two right-angled sides are respectively connected to the connecting member 31 and the positioning member 2.
[0038] In this embodiment, by arranging the reinforcing rib plates 4 at the upper and lower ends of the connecting member 31, the force distribution can be optimized, the force transmission can be made more uniform, and stress concentration can be reduced, thereby improving the connection strength and reliability.
[0039] The triangular reinforcing rib plate 4 can provide a stable support structure, increase the stiffness of the connection part, and prevent relative displacement or deformation of the connecting member 31 and the positioning member 2 during use. Compared with reinforcing rib plates of other shapes, the triangular reinforcing rib plate can make more effective use of materials, reduce material consumption and manufacturing costs on the premise of ensuring strength and stiffness. In addition, the triangular rib plate structure is simple, easy to process, and the connection method with the connecting member 31 and the positioning member 2 is clear, facilitating assembly and installation.
[0040] Furthermore, as a preferred implementation manner rather than a limitation of this solution, no less than two of the adjusting mechanisms 3 are evenly arranged between the two positioning members 2.
[0041] In this embodiment, no less than two adjusting mechanisms 3 are evenly arranged between the two positioning members 2. This means that along the entire length of the positioning member 2, multiple adjusting mechanisms 3 are provided as needed, and these adjusting mechanisms 3 are evenly distributed along the length direction of the positioning member 2. By arranging multiple adjusting mechanisms 3 between the two positioning members 2, more precise adjustment of the forming thickness of the cover side stack can be achieved. It should be specifically noted that each adjusting mechanism 3 can independently adjust the distance between the positioning members 2, so that the thickness of the cover side stack can be locally adjusted as needed, improving the forming accuracy. The setting of multiple adjusting mechanisms 3 can increase the contact area and the number of support points of the device, thereby improving the stability of the device. During the forming process of the cover side stack, it can better resist lateral forces and prevent deformation or displacement of the positioning member 2. For covers of different lengths, the number of adjusting mechanisms 3 can be increased or decreased to adapt, which can improve the versatility of the device, reduce the types of spare parts, and lower the production cost.
[0042] Further, as a preferred implementation manner rather than a limitation of this solution, three of the adjusting mechanisms 3 are evenly arranged between the two positioning members 2, and the three adjusting mechanisms 3 are respectively arranged between the two ends and the middle end of the two positioning members 2.
[0043] In this embodiment, by evenly arranging three adjusting mechanisms 3 between the two positioning members 2 and respectively located between the two ends and the middle end, the force uniformity, structural stability and adjustment efficiency of the device are further improved, and it can better meet the formwork support and fixing position requirements of the cover plate side stacks with different lengths and thicknesses. By arranging the adjusting mechanisms 3 at the two ends and the middle end, the thickness of the cover plate side stack can be quickly adjusted. Construction workers can adjust these three adjusting mechanisms 3 simultaneously or separately according to needs, improving work efficiency.
[0044] Furthermore, as a preferred implementation manner rather than a limitation of this solution, the outer contour of the structure formed by connecting the three adjusting mechanisms 3 and the two positioning members 2 presents a rectangle.
[0045] In this embodiment, the outer contour of the structure formed by connecting the three adjusting mechanisms 3 and the two positioning members 2 presents a rectangle, which means that inside the cover plate forming die 1, the overall shape of the formwork support and fixing device composed of the positioning members 2 and the adjusting mechanisms 3 is a rectangular frame. The rectangular outer contour of the structure matches the internal space shape of the common cover plate forming die, can make full use of the internal space of the die, improve the fitting degree between the device and the die, and thus enhance the formwork support and reinforcement effect on the cover plate side stack.
[0046] Inside the cover plate forming die, the space is usually limited. The rectangular outer contour can better adapt to this space limitation, improve the space utilization rate, and enable the device to play the maximum formwork support and reinforcement role in the limited space. Moreover, the rectangular frame structure is simple and regular, which is convenient for installation and disassembly operations inside the cover plate forming die. Construction workers can quickly put the device into or take it out of the die, improving production efficiency.
[0047] The working principle of the present utility model is as follows:
[0048] This device is mainly used in the production process of precast cover plates to support, reinforce and position the side stacks of the cover plates to ensure the forming quality and dimensional accuracy of the cover plates, and at the same time eliminate problems such as slurry leakage and formwork swelling that may occur in the cast-in-place cover plate solution. Its working principle mainly involves the supporting effect of the positioning members, the thickness adjustment of the adjusting mechanisms, and the collaborative work between various components. The following is a detailed description of its working principle:
[0049] The construction workers install and adjust the device to its initial position. The positioning member 2 in the shape of a metal square tube forms a forming space for the side stack of the cover plate with the two side templates of the cover plate forming die 1 and provides basic lateral support for the side stack of the cover plate.
[0050] According to the required thickness of the side stack of the cover plate, by rotating the adjusting device 32, that is, the threaded sleeve, the screw rod threadedly connected thereto is driven to move. Since the screw rod is fixedly connected to the positioning member 2, the movement of the screw rod will drive the positioning member 2 to move synchronously, thereby adjusting the distance between the two positioning members 2 and realizing the control of the forming thickness of the side stack of the cover plate.
[0051] Three adjusting mechanisms 3 are evenly arranged between the two positioning members 2, respectively located between the two ends and the middle. This can make the force on the side stack of the cover plate more uniform during the forming process and avoid deformation caused by uneven force.
[0052] The setting of the reinforcing rib plate 4 increases the connection strength and overall stiffness between the positioning member 2 and the connecting member 31, and improves the stability of the device. At the same time, the rectangular structure outer contour formed by the connection of the three adjusting mechanisms 3 and the two positioning members 2 also enhances the stability of the device.
[0053] In summary, the adjustable precast cover plate formwork and fixing positioning device provided in this embodiment realizes the precise control of the forming thickness of the side stack of the cover plate through the adjusting mechanism 3, and improves the stability and reliability of the device through reasonable structural design, thereby ensuring the production quality and efficiency of the precast cover plate, and at the same time eliminating problems such as slurry leakage and formwork swelling that may occur in the cast-in-place cover plate scheme.
[0054] The above is the implementation manner provided in combination with specific content, and it is not considered that the specific implementation of this application is only limited to these descriptions. Any similarity to the method structure of this application, or several technical deductions or replacements made under the premise of the concept of this application, should be regarded as the protection scope of this application.
