[0002] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, and the upper and lower surfaces of the slab are flat, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] Composite slab truss reinforcement is a special structural device made by welding several different types of steel bars according to a reasonable structure. It is mainly used in the bottom plate of composite roof slabs. Its main function is to strengthen the compressive strength and toughness of the bottom plate, which can effectively increase the earthquake resistance of the building.

[0004] In existing composite slab truss welding, bracing is often used to support the composite slab truss reinforcement. During the welding process, the components are heavy, and the welder needs external assistance, which wastes a lot of manpower and resources. In addition, there are many types of composite slab truss reinforcement, and the existing equipment cannot adjust the size according to different types of composite slab truss reinforcement, resulting in poor applicability of the equipment and causing many troubles in the welding process.

Specific embodiments

[0023] The following further describes the present utility model in detail with reference to embodiments:

[0025] The carriage 3 is in an inverted U shape.

[0026] In this solution, through the adjustment structure, by adjusting the distance between the carriages 3, the welding process of the laminated plate truss bars is made more time-saving and labor-saving, greatly improving the use effect of the device. Through the support structure, by rotating the rotating rod 46, the position of the connecting rod 47 can be adjusted, and the position of the placed laminated plate can be further positioned to ensure its stable support.

[0027] As Figures 2-3 shown, the adjustment mechanism 2 includes a mounting seat 21, one end of the mounting seat 21 is fixedly installed with the left end of the machine table 1, a double-shaft motor 22 is fixedly provided at the front end of the mounting seat 21, transmission rods 23 are installed at both ends of the double-shaft motor 22, a first cone pulley 24 is fixedly provided at the top of the transmission rod, stabilizing frames 25 are fixedly provided at both ends of the left end of the machine table 1, side plates 26 are symmetrically and fixedly provided on the front and back sides of the machine table 1, a bidirectional screw rod 27 is rotatably installed inside the side plates 26, a second cone pulley 28 is fixedly provided at the top of the bidirectional screw rod 27, and threaded seats 29 are threadedly installed on both sides of the bidirectional screw rod 27.

[0028] The front end inside of the stabilizing frame 25 is rotatably installed through the outside of the transmission rod 23, and the first cone pulley 24 and the second cone pulley 28 are engaged with each other.

[0029] The thread directions on both sides of the bidirectional screw rod 27 are set to be opposite, and the upper ends of the threaded seats 29 are fixedly installed with the bottom ends of the carriage 3.

[0030] In this solution, when welding composite slab truss reinforcement of different specifications, there is no need for tedious manual adjustment of the welding position, which greatly saves time and labor costs. The adjustment of the structure can quickly and accurately complete the spacing adjustment, which significantly improves the efficiency of the composite slab truss reinforcement welding process and greatly enhances the use effect of the device.

[0031] like Figure 4 As shown, the support mechanism 4 includes a baffle 41. The lower end of the baffle 41 is fixedly installed with the upper end of the slide 3. A rotating groove 42 is provided through both sides of the top of the baffle 41. Through holes 43 are provided through both sides of the rotating groove 42. A pentagonal insert 44 is movably installed inside the through hole 43. A horizontal plate 45 is fixedly provided at the front end of the pentagonal insert 44. A rotating rod 46 is provided inside the rotating groove 42. A connecting rod 47 is fixedly provided on the inner side of the bottom end of the rotating rod 46. Sleeves 48 are fixedly provided on both sides of the top of the rotating rod 46. An insertion hole 49 is fixedly provided on the inner side of the bottom end of the rotating rod 46.

[0032] The top of the rotating rod 46 is rotatably connected to the inside of the rotating groove 42, and the insertion hole 49 is opened through the top of the rotating rod 46.

[0033] The outside of the sleeve 48 fits into the inside of the through hole 43 and is rotatably connected.

[0034] Both the through hole 43 and the socket 49 are pentagonal, and the pentagonal plug 44 is installed through the interior of the socket 49.

[0035] In this design, the connecting rod 47 can be adjusted at multiple angles under the drive of the rotating rod 46, which enables the device to adapt and support different types of composite slab truss reinforcement.

[0036] The working principle of the composite plate stabilizing and limiting welding device will be explained in detail below.

[0037] like Figures 1-4As shown, when the composite plate stabilizing and limiting welding device needs to be used, the operator can pull the horizontal plate 45 outward to pull the pentagonal insert 44 out of the insertion hole 49 when the composite plate needs to be supported. Then, the rotating rod 46 can be rotated, which can drive the sleeve 48 to rotate synchronously in the through hole 43. During the rotation of the rotating rod 46, the connecting rod 47 connected to it will move synchronously. In this way, the position of the connecting rod 47 can be flexibly and accurately adjusted according to the actual placement requirements of the composite plate. In this way, the composite plate can be further supported at precise points, ensuring that the composite plate can obtain a stable support effect when placed. Then, the composite plate truss reinforcement to be welded can be placed between the baffles 41. The connecting rods 47 on both sides can support the composite plate truss reinforcement. Finally, it can be accurately passed through the through hole 43 and directly inserted into the corresponding pentagonal insert. The unique shape design of the pentagonal insert 44 and the pentagonal insert 49 inside the hole 49 allows them to form a tight mesh when they are engaged, thus firmly fixing the rotating rod 46. This ensures that the rotating rod 46 is not easily rotated due to external interference during the use of the device, effectively maintaining the stability of the support point. After the composite truss reinforcement is supported, it is convenient for operators to perform welding. By starting the dual-axis motor 22, the dual-axis motor 22 drives the transmission rods 23 on both sides to rotate. The transmission rods 23, through the meshing effect between the first conical wheel 24 and the second conical wheel 28, synchronously drive the bidirectional lead screws 27 on both sides to rotate. The bidirectional lead screws 27 then drive the threaded seats 29 on both sides to move, causing the threaded seats 29 to move the slides 3 on both sides closer or further apart. This allows for synchronous adjustment of the spacing between the rotating rods 46, eliminating the need for tedious manual adjustment of the welding position when dealing with composite truss reinforcement of different specifications.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
