Description
Technical Field
[0001] This invention belongs to the field of composite slab technology, specifically relating to a portable quick positioning and adjustment device for use with prefabricated composite slabs. Background Technology
[0002] In the current construction industry, precast composite slabs are increasingly favored by building owners and engineers due to their advantages such as high production efficiency, fast construction speed, and easy quality control. However, despite the obvious advantages of precast composite slabs in many aspects, there are still some challenges and problems in the installation process.
[0003] First, the installation of precast composite slabs requires precise positioning. In actual construction, positional deviations between precast composite slabs can significantly affect their load-bearing performance and may even threaten the safety of the building structure. Due to the variety of specifications and models of precast composite slabs, the complexity and difficulty of their installation process are further increased. Existing positioning and adjustment devices have some limitations, often requiring a large amount of manual intervention during operation, which is not only inefficient but also prone to errors. Existing equipment is usually unable to adapt to various specifications and models of precast composite slabs, resulting in poor equipment versatility and inability to meet the diverse needs of construction sites.
[0004] To address the aforementioned problems, this invention proposes a portable, rapid positioning and adjustment device for use with precast composite slabs. The purpose is to solve the positioning problem during the installation of precast composite slabs so as to quickly complete the positioning and installation work of precast composite slabs and improve the installation efficiency of precast composite slabs. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides a portable, rapid positioning and adjustment device for use with precast composite slabs.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a portable quick positioning and adjustment device for use with precast composite slabs, wherein the precast composite slab to be installed includes a composite slab part and a reinforcing bar part, and the portable quick positioning and adjustment device for use with precast composite slabs includes a positioning and adjustment mechanism group, wherein the positioning and adjustment mechanism group includes positioning and adjustment mechanism one, positioning and adjustment mechanism two, positioning and adjustment mechanism three and positioning and adjustment mechanism four, and the installed composite slab part is horizontal and respectively engaged with the lower inner side of positioning and adjustment mechanism one, the lower inner side of positioning and adjustment mechanism two, the lower inner side of positioning and adjustment mechanism three and the lower inner side of positioning and adjustment mechanism four;
[0007] The positioning adjustment mechanism one, positioning adjustment mechanism two, positioning adjustment mechanism three and positioning adjustment mechanism four each include a positioning component and a fixing component. The positioning component is inclined vertically from bottom to top towards the side away from the stacked plate portion on the side closest to the stacked plate portion.
[0008] Preferably, the positioning component includes a trapezoidal positioning part, which includes a trapezoidal plate and a trapezoidal plate support bracket. There are multiple trapezoidal plates, and the trapezoidal plate support bracket is installed on the side of the trapezoidal plate away from the overlapping plate portion.
[0009] Preferably, all of the trapezoidal plates are slidably connected to the trapezoidal plate support.
[0010] Preferably, the fixing component includes a horizontal fixing member, which is plate-shaped and is installed on the lower end of the outer side of the trapezoidal plate.
[0011] Preferably, a plurality of ball bearings are installed on the side of the trapezoidal plate near the composite plate portion;
[0012] Alternatively, multiple needle rollers may be installed on the side of the trapezoidal plate near the composite plate, with the axis of the needle rollers being horizontal.
[0013] Preferably, the positioning component includes an arc-shaped positioning component, which includes an arched plate, wherein the side of the arched plate closest to the composite plate portion is arched.
[0014] Preferably, the positioning component includes a variable angle positioning part, which includes a horizontal plate, an inclined plate, and a telescopic part. The horizontal plate and the inclined plate are hinged together, and the two ends of the telescopic part are detachably connected to the horizontal plate and the inclined plate, respectively. A steel bar slot is provided on the inclined plate.
[0015] Preferably, the portable quick positioning and adjustment device for use with precast composite slabs further includes a pressure sensor group and a controller. The pressure sensor group includes pressure sensor one, pressure sensor two, pressure sensor three, and pressure sensor four. Pressure sensor one is installed on the side of positioning and adjustment mechanism one near the composite slab, pressure sensor two is installed on the side of positioning and adjustment mechanism two near the composite slab, pressure sensor three is installed on the side of positioning and adjustment mechanism three near the composite slab, and pressure sensor four is installed on the side of positioning and adjustment mechanism four near the composite slab. Pressure sensor one, pressure sensor two, pressure sensor three, and pressure sensor four are all communicatively connected to the controller, and the telescopic component is also communicatively connected to the controller.
[0016] Preferably, the fixing component includes a triangular stabilizing support, which is installed at the lower end of the positioning component.
[0017] Preferably, the fixing component includes an ear hook that is mounted on the side of the positioning component.
[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows:
[0019] (1) The positioning component is tilted vertically from bottom to top towards the side away from the composite slab on the side closest to the composite slab, which improves the positioning accuracy. The positioning adjustment mechanism group around the precast composite slab realizes the three-dimensional accurate positioning of the precast composite slab during the hoisting process, ensuring the accurate position of the composite slab during the installation process. Through the positioning component and the level adjustment instrument, the precast composite slab is accurately adjusted in real time during the hoisting process, which greatly improves the adjustment efficiency, shortens the hoisting time of the composite slab, and improves the on-site hoisting efficiency.
[0020] (2) The positioning components include trapezoidal positioning parts. The trapezoidal positioning parts are simple to manufacture, have low construction costs, and are easy to maintain. The horizontal fixing parts are installed on the lower end of the outer side of the trapezoidal plate. The horizontal fixing parts play a role in fixing the trapezoidal plate, ensuring the safety of hoisting and the accuracy of positioning.
[0021] (3) There are multiple trapezoidal plates, and the steel bars are located in the gap between multiple trapezoidal plates. During positioning, the positioning difficulty will not be increased due to the interference of the steel bars. Multiple trapezoidal plates are slidably connected to the trapezoidal plate support bracket. The spacing between multiple trapezoidal plates is adjustable. It can be adapted to the position and size of the steel bars of different precast composite slabs. It has strong adaptability and wide application range.
[0022] (4) Multiple rollers are installed on the side of the trapezoidal plate near the composite plate. The rollers are in rolling connection with the composite plate. Compared with sliding, the rolling connection reduces the friction between the rollers and the composite plate, making the relative movement smoother.
[0023] (5) The positioning component includes a variable angle positioning component, which changes the angle between the horizontal plate and the inclined plate to ensure that the overlapping plate part and the inclined plate are more likely to slide relative to each other, thus shortening the hoisting time and improving the hoisting efficiency.
[0024] (6) The portable quick positioning and adjustment device for use with precast composite slabs also includes a pressure sensor group. The angle between the horizontal plate and the inclined plate can be changed by the telescopic component, eliminating the need to manually change the angle and saving manpower. In addition, the pressure sensor group controls the synchronous movement of the inclined plate that needs to change the angle, which improves efficiency. Attached Figure Description

[0044] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0045] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.
[0046] Example 1
[0047] The following is combined Figures 1 to 5 Specific instructions for portable quick positioning and adjustment devices used with precast composite slabs, such as... Figure 1 and Figure 3 As shown, a portable quick positioning and adjustment device for use with precast composite slabs is disclosed. The precast composite slab 4 to be installed includes a composite slab portion 41 and a reinforcing bar portion 42. The portable quick positioning and adjustment device for use with precast composite slabs includes a positioning and adjustment mechanism group 1, which includes a positioning and adjustment mechanism one 11, a positioning and adjustment mechanism two 12, a positioning and adjustment mechanism three 13, and a positioning and adjustment mechanism four 14. The installed composite slab portion 41 is horizontal and is respectively engaged with the lower inner surface of the positioning and adjustment mechanism one 11, the lower inner surface of the positioning and adjustment mechanism two 12, the lower inner surface of the positioning and adjustment mechanism three 13, and the lower inner surface of the positioning and adjustment mechanism four 14. The shortest distance between the bottom surface of the positioning and adjustment mechanism one 11 and the bottom surface of the positioning and adjustment mechanism two 12 is equal to the length of the composite slab portion 41, and the shortest distance between the bottom surface of the positioning and adjustment mechanism three 13 and the bottom surface of the positioning and adjustment mechanism four 14 is equal to the width of the composite slab portion 41.
[0048] like Figure 2 and Figure 4 As shown, positioning adjustment mechanism 11, positioning adjustment mechanism 2 12, positioning adjustment mechanism 3 13 and positioning adjustment mechanism 4 14 all include positioning component 2 and fixing component 3. The side of positioning component 2 closest to the composite plate part 41 is inclined vertically from bottom to top toward the side away from the composite plate part 41.
[0049] like Figure 2 and Figure 5As shown, the positioning component 2 includes a trapezoidal positioning part 21, which includes a trapezoidal plate 22 and a trapezoidal plate support 23. There are multiple trapezoidal plates 22, and the trapezoidal plate support 23 is installed on the side of the trapezoidal plate 22 away from the overlapping plate part 41.
[0050] Multiple trapezoidal plates 22 are slidably connected to trapezoidal plate support brackets 23.
[0051] like Figure 2 As shown, the fixing component 3 includes a horizontal fixing member 31, which is plate-shaped and is installed on the lower end of the outer side of the trapezoidal plate 22.
[0052] Multiple ball bearings are installed on the side of the trapezoidal plate 22 near the composite plate portion 41.
[0053] like Figure 2 and Figure 5 As shown, the fixing component 3 includes a triangular stabilizing support 7, which is installed at the lower end of the positioning component 2.
[0054] like Figure 2 and Figure 5 As shown, the fixing component 3 includes an ear hook 6, which is mounted on the side of the positioning component 2.
[0055] The portable quick positioning and adjustment device for use with precast composite slabs also includes an L-shaped telescopic bracket 9. The positioning adjustment mechanism 11, positioning adjustment mechanism 212, positioning adjustment mechanism 313, and positioning adjustment mechanism 414 are detachably connected by the L-shaped telescopic bracket 9. The L-shaped telescopic bracket 9 is marked with scales, which are used to assist in the positioning of the positioning adjustment mechanism group 1, ensuring more accurate positioning. The L-shaped telescopic bracket 9 is made of metal and plays a supporting role, ensuring that the positioning adjustment mechanism group 1 does not undergo relative displacement after being fixed in the position. The L-shaped telescopic bracket 9 adapts to precast composite slabs 4 of different specifications by its own telescopic extension.
[0056] The portable quick positioning and adjustment device for use with precast composite slabs also includes a leveling device 8. During the positioning of the precast composite slab 4, the leveling device 8 is placed above the composite slab section 41, and the positioning is assisted by observing the leveling device 8.
[0057] Operating steps of the portable quick positioning and adjustment device for use with precast composite slabs:
[0058] Step 1: Place the four trapezoidal positioning components 21 in the designated positions. The shortest distance between the bottom surface of positioning adjustment mechanism 11 and the bottom surface of positioning adjustment mechanism 212 is equal to the length of the stacked plate part 41, and the shortest distance between the bottom surface of positioning adjustment mechanism 313 and the bottom surface of positioning adjustment mechanism 44 is equal to the width of the stacked plate part 41.
[0059] Step 2: Lift the precast composite slab 4, and then after the precast composite slab 4 has fallen to a certain height, place the leveling device 8 on the upper end of the composite slab part 41.
[0060] Step 3: The precast composite slab 4 continues to fall. Workers align the composite slab part 41 with the square area enclosed by the four trapezoidal positioning components 21. Since the area of the square area enclosed by the upper ends of the four trapezoidal positioning components 21 is larger than the area of the composite slab part 41, it is easy to place the composite slab part 41 into the square area enclosed by the upper ends of the four trapezoidal positioning components 21. The steel reinforcement part 42 close to the four trapezoidal positioning components 21 passes through the gap between the multiple trapezoidal plates 22.
[0061] Step 4: The precast composite slab 4 continues to fall, and the precast composite slab 4 contacts the side of the trapezoidal plate 22 of one or more trapezoidal positioning components 21;
[0062] Step 5: The precast composite slab 4 continues to fall, and the side of the composite slab portion 41 that contacts the side of the trapezoidal plate 22 of the trapezoidal positioning component 21 falls until the plane where the composite slab portion 41 is located is horizontal.
[0063] Example 2
[0064] The difference between this embodiment and Embodiment 1 is: Figure 6 As shown, the positioning component 2 includes an arc-shaped positioning component, which includes an arched plate 28. The side of the arched plate 28 closest to the composite plate portion 41 is arched.
[0065] Example 3
[0066] The difference between this embodiment and Embodiment 1 is: Figure 7 As shown, multiple needle rollers 29 are installed on the side of the trapezoidal plate 22 near the composite plate portion 41, and the axis of the needle rollers 29 is horizontal.
[0067] Example 4
[0068] The difference between this embodiment and Embodiment 1 is: Figure 8 and Figure 9 As shown, the positioning component 2 includes a variable angle positioning component 24, which includes a horizontal plate 25, an inclined plate 26, and a telescopic component 27. The horizontal plate 25 and the inclined plate 26 are hinged together. The two ends of the telescopic component 27 are detachably connected to the horizontal plate 25 and the inclined plate 26, respectively. The inclined plate 26 has a steel bar slot. The telescopic component 27 is a jack or a telescopic cylinder.
[0069] The portable quick positioning and adjustment device for use with precast composite slabs also includes a pressure sensor group and a controller. The pressure sensor group includes pressure sensor one, pressure sensor two, pressure sensor three and pressure sensor four. Pressure sensor one is installed on the side of positioning adjustment mechanism one 11 near the composite slab part 41, pressure sensor two is installed on the side of positioning adjustment mechanism two 12 near the composite slab part 41, pressure sensor three is installed on the side of positioning adjustment mechanism three 13 near the composite slab part 41, and pressure sensor four is installed on the side of positioning adjustment mechanism four 14 near the composite slab part 41. Pressure sensor one, pressure sensor two, pressure sensor three and pressure sensor four are all communicatively connected to the controller, and the telescopic component 27 is communicatively connected to the controller.
[0070] The telescopic component 27 is a telescopic cylinder.
[0071] Since the shortest distance between the bottom surfaces of positioning adjustment mechanism 11 and positioning adjustment mechanism 212 is equal to the length of the composite plate portion 41, and the shortest distance between the bottom surfaces of positioning adjustment mechanism 313 and positioning adjustment mechanism 414 is equal to the width of the composite plate portion 41, generally two of the positioning adjustment mechanisms 11, 212, 313 and 414 will be in contact with the composite plate portion 41.
[0072] When any two of the pressure sensors 1, 2, 3, and 4 are squeezed by the overlapping plate 41, a signal is sent to the controller when the pressure reaches the set value. The controller then sends a signal to the corresponding two telescopic cylinders, which extend synchronously. This increases the angle between the horizontal plate 25 and the inclined plate 26, making it easier for the overlapping plate 41 to slide down. Since the two telescopic cylinders extend synchronously, the overlapping plate 41 reaches the designated position faster, saving time.
[0073] As a technical solution of the present invention, the provided hardware configuration of pressure sensor 1, pressure sensor 2, pressure sensor 3, pressure sensor 4 and telescopic component 27 is only to facilitate the implementation of specific braking control based on the hardware facilities. How to implement braking control and the braking control method are not the technical problems to be solved or the objects of protection of the present invention. At the same time, the communication methods between the devices all adopt existing communication methods, which are not the inventive points of this application.
[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
