Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable multi-functional diagonal bracing device for precast wall panels. Background Technology

[0002] With the rapid development of industrialized construction, prefabricated buildings are gradually becoming a development trend in the construction industry due to their advantages such as high construction efficiency and energy conservation and environmental protection. As a key component of prefabricated buildings, the installation quality and efficiency of prefabricated wall panels directly affect the overall performance and construction cycle of the building. Currently, diagonal bracing devices are widely used in the installation process of prefabricated wall panels for temporary support and positioning. This utility model is an adjustable multi-functional diagonal bracing device for prefabricated wall panels.

[0003] Currently, most precast wall panel bracing devices use single-direction threaded adjustment or segmented splicing structures, requiring the separate operation of multiple components to adjust the length of the upper and lower support rods. This process is not only cumbersome and prone to cumulative errors, but also requires the assistance of tools such as wrenches, resulting in long adjustment times and difficulty in quickly adapting to the installation needs of wall panels with different tilt angles, significantly reducing construction efficiency. Utility Model Content

[0004] This disclosure relates to an adjustable multi-functional diagonal bracing device for prefabricated wall panels, in order to solve the technical problems mentioned in the background art.

[0005] In a first aspect, this disclosure provides an adjustable multi-functional diagonal bracing device for precast wall panels, specifically comprising: an outer cylinder; the upper and lower ends of the outer cylinder are provided with internal threads of opposite directions, and two observation holes are provided on the outer cylinder; a lower support rod and an upper support rod are respectively threaded to the upper and lower ends of the outer cylinder; a connecting plate is installed on both the lower and upper support rods; the connecting plate is provided with a perforated groove; a connecting shaft is connected between the lower support rod and the connecting plate near the lower end of the outer cylinder, and between the upper support rod and the connecting plate near the upper end of the outer cylinder; the rear end of the connecting shaft is provided with a perforated structure, and the front end of the connecting shaft is provided with a through hole; a stop rod is installed in the through hole; a No. 1 spring is sleeved on the connecting shaft; a bottom plate is welded to the connecting plate near the lower end of the lower support rod, and a top plate is welded to the connecting plate near the upper end of the upper support rod.

[0006] In at least some embodiments, a toothed plate is fixed on the base plate, and the lower end of the toothed plate is configured with a tooth-shaped structure.

[0007] In at least some embodiments, four fixing cylinders are fixed to the lower end of the base plate, a rotating rod is rotatably mounted inside the fixing cylinder, a knob is fixed to the upper end of the rotating rod, and an end cap is fixed to the lower end of the fixing cylinder.

[0008] In at least some embodiments, the end cap has four sliding grooves, a slider slides in the grooves, and a telescopic rod is fixed on the slider.

[0009] In at least some embodiments, a rotatable rotating disk is mounted on the end cap, and four elastic plates are mounted on the rotating disk via pins. The end of the elastic plate away from the rotating disk is connected to a slider via a pin, and the lower end of the rotating rod is fixedly connected to the rotating disk.

[0010] In at least some embodiments, a contact plate is installed on the top plate, and four screws are fixed on the contact plate. All four screws are movable on the top plate, and movable plates are movable on the four screws. A second spring is sleeved on the screws, and the second spring is located between the movable plate and the contact plate.

[0011] In at least some embodiments, four fixed seats are fixed on the top plate, and each of the four fixed seats is threaded with an adjusting bolt. The adjusting bolt is provided with a conical surface, and a movable rod is movably mounted on the fixed seat. The upper end of the movable rod is provided with an inclined surface, which contacts the conical surface on the adjusting bolt, and the lower end of the movable rod rests on the movable plate.

[0012] This utility model provides an adjustable multi-functional diagonal bracing device for precast wall panels, which has the following beneficial effects:

[0013] In this invention, the upper and lower ends of the outer cylinder are provided with internal threads of opposite directions, which are threaded to the lower support rod and the upper support rod respectively. This unique design allows the extension length of the lower support rod and the upper support rod to be adjusted synchronously by rotating the outer cylinder, so as to realize the convenient adjustment of the overall height of the diagonal bracing device. Without complicated tools and operating procedures, it can quickly adapt to prefabricated wall panels of different heights, greatly improving installation efficiency and enhancing the versatility of the device.

[0014] Furthermore, in this invention, the structure consisting of the contact plate, screw, movable plate, and second spring at the top plate can provide elastic clamping force to the precast wall panel during installation, achieving temporary fixation and preventing displacement of the wall panel during adjustment. At the same time, by adjusting the bolt, fixing seat, and movable rod, the pressure of the movable rod on the movable plate can be precisely controlled, further adjusting the clamping force to ensure that the wall panel can be stably fixed under different working conditions.

[0015] Furthermore, in this invention, rotating the first knob causes the rotating rod to rotate, which in turn drives the rotating disk to rotate, causing the elastic plate to push the slider to extend the telescopic rod and embed it into the soil. This allows the device to penetrate deep into the soil when facing complex construction environments such as outdoor areas and soft soil foundations, using the soil resistance to achieve stable fixation, greatly enhancing the device's gripping ability and anti-overturning performance.

[0016] Furthermore, in this invention, the toothed structure at the lower end of the toothed groove plate on the base plate can tightly engage with the ground or other supporting surfaces, enhancing the overall stability of the device and preventing slippage or tilting during construction. The observation hole allows construction personnel to visually observe the thread engagement of the lower support rod, upper support rod, and outer cylinder. The observation hole can be used to observe the changes in the extension length of the lower support rod and upper support rod during the thread engagement process. Combined with the pre-set installation height requirements, the rotation of the outer cylinder can be stopped in time to ensure that the diagonal bracing device reaches the required height, avoiding the impact on the installation accuracy of the precast wall panel due to over-adjustment or under-adjustment.

[0017] Furthermore, in this invention, the lower support rod, upper support rod, and connecting plate are connected by a connecting shaft. The toothed structure at the rear end of the connecting shaft is engaged with the toothed groove of the connecting plate, allowing for flexible adjustment at multiple angles. During installation, this design can quickly adapt to prefabricated wall panels with different tilt angle requirements without complex disassembly and reassembly. After adjustment, the No. 1 spring provides elasticity to ensure the toothed structure is tightly engaged, ensuring a stable and fixed angle and preventing the wall panel angle from shifting due to external forces. This adjustable angle design greatly enhances the applicability of the diagonal bracing device, accurately addressing both conventional vertical installation and special angle installation needs. It effectively ensures the accuracy and reliability of prefabricated wall panel installation, reduces the risk of rework due to angle deviation, and improves construction efficiency and quality.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Please refer to Figures 1 to 7 Example 1:

[0032] This utility model proposes an adjustable multi-functional diagonal bracing device for precast wall panels, comprising: an outer cylinder 1; the upper and lower ends of the outer cylinder 1 are provided with internal threads of opposite directions, and two observation holes 11 are opened on the outer cylinder 1; a lower support rod 12 and an upper support rod 13 are respectively threaded to the upper and lower ends of the outer cylinder 1; a connecting plate 2 is installed on both the lower support rod 12 and the upper support rod 13; the connecting plate 2 is provided with a toothed groove; a connecting shaft 121 is connected between the lower support rod 12 and the connecting plate 2 near the lower end of the outer cylinder 1, and between the upper support rod 13 and the connecting plate 2 near the upper end of the outer cylinder 1; the rear end of the connecting shaft 121 is provided with a toothed structure, and the front end of the connecting shaft 121 is provided with a through hole; a stop rod 122 is installed in the through hole; a No. 1 spring 123 is sleeved on the connecting shaft 121; a bottom plate 21 is welded to the connecting plate 2 near the lower end of the lower support rod 12; and a top plate 3 is welded to the connecting plate 2 near the upper end of the upper support rod 13.

[0033] In this embodiment of the disclosure, a toothed plate 22 is fixed on the base plate 21. The lower end of the toothed plate 22 is configured with a toothed structure. Its function is: the toothed structure can significantly increase the contact friction between the base plate 21 and the ground or support surface. The toothed structure at the lower end of the toothed plate 22 can be effectively embedded in the ground to prevent the base plate 21 from sliding, thereby enhancing the stability of the entire inclined bracing device and ensuring that the prefabricated wall panel remains stable during installation.

[0034] In Example 2, based on Example 1, four fixed cylinders 23 are fixed to the lower end of the base plate 21. A rotating rod 231 rotates inside each fixed cylinder 23. A knob 2311 is fixed to the upper end of each rotating rod 231. An end cap 232 is fixed to the lower end of each fixed cylinder 23. The end cap 232 has four sliding grooves, within which slide blocks 2322 slide. A telescopic rod 2324 is fixed to each slide block 2322. A rotatable rotating disk 2321 is mounted on the end cap 232. Four elastic plates 2323 are mounted on the rotating disk 2321 via pins. The ends of the elastic plates 2323 away from the rotating disk 2321 are connected to the slide blocks 2322 via pins. The lower end of the rotating rod 231 is fixedly connected to the rotating disk 2321. Its function is: when the construction worker rotates the knob 2311, the rotating rod 2321 fixedly connected to the knob 2311... 31 rotates accordingly. Since the lower end of the rotating rod 231 is fixedly connected to the rotating disk 2321, it drives the rotating disk 2321 to rotate. The four elastic plates 2323 installed on the rotating disk 2321 by pins will change angle as the rotating disk 2321 rotates. The end of the elastic plate 2323 away from the rotating disk 2321 is connected to the slider 2322 by pins. During the process of the elastic plate 2323 changing angle, it will push the slider 2322 to slide in the groove of the end cover 232, so that the telescopic rod 2324 fixed to the slider 2322 extends or retracts. When encountering relatively soft ground, turn the first knob 2311 to make the telescopic rod 2324 extend and penetrate into the soil. By using the resistance of the soil to the telescopic rod 2324, the gripping ability of the inclined bracing device is greatly enhanced, preventing the device from tilting or shifting during the installation of the precast wall panel.

[0035] In Example 3, based on Examples 1 and 2, a contact plate 31 is installed on the top plate 3. Four screws are fixed on the contact plate 31, and all four screws are movable on the top plate 3. Movable plates 32 are movable on the four screws, and a second spring 311 is sleeved on the screws. The second spring 311 is located between the movable plate 32 and the contact plate 31. Four fixed seats 33 are fixed on the top plate 3, and each of the four fixed seats 33 is threaded with an adjusting bolt 332. The adjusting bolt 332 is provided with a conical surface, and a movable rod 331 is movable on the fixed seat 33. The upper end of the movable rod 331 is set as an inclined surface, which contacts the conical surface on the adjusting bolt 332. The lower end of the movable rod 331 rests on the movable plate 32. Its function is as follows: When installing precast wall panels, the contact plate 31 contacts the surface of the wall panel. In the initial stage of installation, the elasticity of the second spring 311 enables the movable plate 32 to generate a pre-tightening force on the wall panel, thereby temporarily fixing the wall panel and preventing displacement of the wall panel during the initial positioning process. When the adjusting bolt 332 is rotated, the conical surface on the adjusting bolt 332 contacts the inclined surface at the upper end of the movable rod 331. The rotation of the adjusting bolt 332 will be converted into the up and down movement of the movable rod 331 within the fixed seat 33. The lower end of the movable rod 331 presses against the movable plate 32. Its up and down movement will squeeze or release the movable plate 32, thereby changing the compression degree of the second spring 311 and achieving precise adjustment of the clamping force on the wall panel.

[0036] The working principle of this embodiment is as follows: First, the diagonal bracing device is moved to the vicinity of the precast wall panel installation position. The base plate 21 is placed on the ground. The toothed structure at the lower end of the toothed plate 22 on the base plate 21 tightly engages with the ground, using the increased friction to initially fix the position of the diagonal bracing device and prevent the device from sliding during subsequent operations. If the installation environment is a soft ground, the stability of the device needs to be further enhanced. Rotate the first knob 2311. The first knob 2311 drives the rotating rod 231 to rotate. The lower end of the rotating rod 231 is fixedly connected to the rotating disk 2321, thereby driving the rotating disk 2321 to rotate. The elastic plate 2323 on the rotating disk 2321 rotates with the rotating disk 2321. When rotation 321 changes angle, the elastic plate 2323 is connected to the slider 2322 via a pin. During the angle change, the slider 2322 is pushed to slide within the groove of the end cap 232, causing the telescopic rod 2324, fixed to the slider 2322, to extend and penetrate into the soil. The penetration depth of the telescopic rod 2324 can be adjusted by controlling the number of rotations of knob 2311. Soil resistance enhances the grip of the inclined support device, preventing tilting or displacement. Rotating the outer cylinder 1 causes the lower support rod 12 and the upper support rod 13 to move synchronously and in opposite directions according to the threaded transmission principle, thus adjusting the overall height of the inclined support device. The observation hole 11 on the outer cylinder 1 facilitates construction. Workers observe the thread engagement of the lower support rod 12 and upper support rod 13 with the outer cylinder 1, precisely controlling the adjustment height to match the installation height requirements of the precast wall panel. The lower support rod 12, upper support rod 13, and connecting plate 2 are connected by connecting shaft 121. The toothed structure at the rear end of connecting shaft 121 engages with the toothed groove on connecting plate 2. Pushing connecting shaft 121 backward separates the toothed structure from the toothed groove, allowing for rotational adjustment within a certain angle range. After adjustment, spring 123 provides a certain elastic force, ensuring a tight engagement between the toothed structure of connecting shaft 121 and the toothed groove of connecting plate 2, preventing angle deviation during subsequent operations. The top plate 3 is then moved closer to the precast wall. The contact plate 31 contacts the wall panel surface. In the initial stage of installation, the second spring 311 is in a compressed state. Its elasticity causes the movable plate 32 to generate a pre-tightening force on the wall panel, thereby temporarily fixing the wall panel and preventing displacement of the wall panel during initial positioning. If precise adjustment of the tightening force on the wall panel is required, rotate the adjusting bolt 332. The conical surface on the adjusting bolt 332 contacts the inclined surface at the upper end of the movable rod 331. The rotational movement of the adjusting bolt 332 is converted into the up-and-down movement of the movable rod 331 within the fixed seat 33. By changing the compression degree of the second spring 311 through the movable plate 32, the precise adjustment of the tightening force on the wall panel can be achieved, ensuring that the wall panel is firmly fixed.
