Description

Technical Field

[0001] The present application relates to the technical field of concrete pavement, and in particular to an auxiliary device for welding angle steels of prefabricated concrete pavement panels. Background Art

[0002] Nowadays, most of the roads in cities are concrete roads. In order to facilitate the construction of concrete roads, prefabricated concrete road panels have appeared.

[0003] Precast concrete road panels are concrete panels that are prefabricated in factories or on site and are used in road construction. Precast concrete includes a formwork to limit the range of concrete pouring. Steel mesh connection points are set inside the formwork, and angle steels are required to be set around the inner surface of the formwork to protect the edges of the concrete. The adjacent angle steel connections need to be welded before pouring concrete into the formwork.

[0004] The above-mentioned existing technical solutions have the following defects: when welding the angle steel, workers are required to hold the angle steel, or directly use steel bars to press the angle steel against the edge of the inner surface of the template. Both methods are unstable in supporting the angle steel and are time-consuming and labor-intensive. Utility Model Content

[0005] In order to make the welding of angle steel more convenient and smooth, the present application provides a precast concrete road slab angle steel welding auxiliary device.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A precast concrete road slab angle steel welding auxiliary device comprises a top plate and a bottom plate, wherein one end of the top plate and the bottom plate are connected, and there is a certain distance between the top plate and the bottom plate, and a connection structure is arranged at one end of the top plate away from the bottom plate to connect with a template.

[0008] By adopting the above scheme, the angle steel is clamped by using the top plate and the bottom plate, and the top plate and the connecting structure are fixed by the connecting structure, so that the angle steel is fixed to the inner surface of the template, so that the angle steel will not move when the workers are welding the angle steel, making the angle steel welding more convenient and smooth.

[0009] Optionally, the connection structure includes nuts and bolts, a circular hole is opened on the surface of the top plate, the bolt passes through the circular hole and is rotatably connected to the top plate, the nut is connected to the bolt, and the nut is connected to the template.

[0010] By adopting the above scheme, the bolts and nuts are tightened, so that the top plate and the template are clamped between the bolts and nuts, thereby fixing the top plate template and facilitating the installation and removal of the top plate.

[0011] Optionally, the nut of the bolt is located above the top plate, and the nut is arranged below the top plate.

[0012] By adopting the above scheme, the upper part of the template is kept as flat as possible, which not only makes the surface of the template more beautiful, but also makes the surface of the template safer by turning the bolts downward.

[0013] Optionally, a shaft rod is rotatably connected to one end of the top plate away from the connection structure, and the shaft rod is connected to the bottom plate.

[0014] By adopting the above scheme, when installing the auxiliary device, the bottom plate can be first rotated to the side away from the template, and then the connection structure is used to fix the top plate to the template. Then the bottom plate is rotated again so that the bottom plate and the top plate clamp the angle steel, thereby making the installation of the auxiliary structure more convenient.

[0015] Optionally, a thread is provided on the surface of the shaft rod, a threaded sleeve is connected to the lower end of the shaft rod, a thread is provided in the threaded sleeve, the shaft rod and the threaded sleeve are connected by threads, and the threaded sleeve is connected to the bottom plate.

[0016] By adopting the above scheme, after the top plate and the bottom plate clamp the angle steel, the shaft rod can be rotated. Since the shaft rod and the threaded sleeve are connected by threads, when the shaft rod rotates, the top plate and the bottom plate approach each other, thereby clamping the angle steel more firmly and making the fixation of the angle steel more stable.

[0017] Optionally, a knob is fixedly connected to the upper end of the shaft rod.

[0018] By adopting the above scheme, the operator can rotate the shaft rod more conveniently.

[0019] Optionally, a through hole is provided on the surface of the bottom plate, the threaded sleeve is rotatably connected in the through hole, a rod hole is provided on the surface of the bottom plate away from the shaft rod, the rod hole communicates with the through hole, and a top rod is slidably connected in the rod hole, and the top rod is connected with a spring.

[0020] By adopting the above scheme, when the worker rotates the bottom plate, the threaded sleeve is rotatably connected to the bottom plate, so that the threaded sleeve does not move when the bottom plate rotates. When the bottom plate rotates to be parallel to the top plate, the angle steel presses the top rod into the rod hole, the top rod compresses the spring, and the other end of the top rod abuts against the surface of the threaded sleeve, thereby fixing the threaded sleeve to the bottom plate. Then the operator can drive the bottom plate to rise and fall when rotating the shaft rod.

[0021] Optionally, the top rod is a top rod with a spherical shape at one end away from the through hole.

[0022] By adopting the above scheme, the top rod can be more smoothly pressed into the top groove when the bottom plate rotates.

[0023] In summary, the present application has the following technical effects:

[0024] 1. By providing a top plate and a bottom plate to clamp the angle steel, the angle steel is fixed, thereby facilitating the worker to weld the angle steel;

[0025] 2. By opening a thread on the outside of the shaft and connecting it with the threaded sleeve, the top plate and the bottom plate can clamp the angle steel when the worker rotates the shaft, making the angle steel more firmly fixed;

[0026] 3. The top plate is connected to the template by setting bolts and nuts, making the installation and disassembly of the top plate more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 , a prefabricated concrete road slab angle steel welding auxiliary device, including a top plate 1 and a bottom plate 2, the top plate 1 and the bottom plate 2 are connected at one end, and there is a certain distance between the top plate 1 and the bottom plate 2, and a connecting structure 3 is set at the end of the top plate 1 away from the bottom plate 2 to connect with the template 7. When the angle steel 6 needs to be fixed, the top plate 1 and the bottom plate 2 are used to clamp the angle steel 6, and the top plate 1 and the connecting structure 3 are fixed by the connecting structure 3, so that the angle steel 6 is fixed to the inner surface of the template 7, so that the angle steel 6 will not move when the worker is welding the angle steel 6, so that the angle steel 6 is welded more conveniently and smoothly.

[0033] Reference Figure 1 and Figure 2 The connection structure 3 includes a nut 32 and a bolt 31. A circular hole is opened on the surface of the top plate 1. The bolt 31 passes through the circular hole and is rotatably connected to the top plate 1. The nut 32 is connected to the bolt 31. The bolt 31 faces downward, and the bolt 31 passes through the template 7. The nut is screwed into the bolt 31 under the bolt 31, thereby fixing the top plate 1 and the template 7. The above technical solution makes the connection between the top plate 1 and the template 7 more convenient, and the bolt 31 facing downward can make the surface of the template 7 smoother, which not only makes the surface of the template 7 more beautiful, but also safer.

[0034] Reference Figure 2, a shaft rod 4 is rotatably connected to one end of the top plate 1 away from the bolt 31. A knob 41 is fixedly connected to the upper end of the shaft rod 4, enabling the operator to rotate the shaft rod 4 more conveniently. Threads are provided on the surface of the shaft rod 4, and a threaded sleeve 5 is threadedly connected to the outside of the shaft rod 4. Threads are provided on the inner side of the threaded sleeve 5. A through hole 21 is provided at one end of the surface of the bottom plate 2, and a rotating groove is provided on the inner side wall of the through hole 21. The diameter of the rotating groove is larger than that of the through hole 21. The threaded sleeve 5 is rotatably connected in the rotating groove, thereby limiting the threaded sleeve 5. When installing the auxiliary device, the bottom plate 2 can be first rotated to the side away from the template 7, and then the connecting structure 3 is used to fix the top plate 1 and the template 7. Then the bottom plate 2 is rotated again so that the bottom plate 2 and the top plate 1 clamp the angle steel 6. Then the knob 41 can be rotated to clamp the angle steel 6 by the top plate 1 and the bottom plate 2, so that the angle steel 6 is fixed more firmly.

[0035] Refer to Figure 2 and Figure 3 , a rod hole 22 is provided at one end of the bottom plate 2 away from the shaft rod 4. The rod hole 22 communicates with the rotating groove. A top rod 23 is slidably connected in the rod hole 22, and a spring 24 is sleeved on the outside of the top rod 23. The other end of the spring 24 communicates with the inner wall of the rod hole 22. A rubber head is fixedly connected to one end of the top plate 1 close to the threaded sleeve 5, and the end of the top rod 23 away from the threaded sleeve 5 is spherical. When the worker rotates the bottom plate 2, the threaded sleeve 5 is rotatably connected to the bottom plate 2, so that the threaded sleeve 5 does not move when the bottom plate 2 rotates. When the bottom plate 2 rotates to be parallel to the top plate 1, the angle steel 6 presses the top rod 23 into the rod hole 22. The spherical shape of this end of the top rod 23 can reduce the friction between the top rod 23 and the angle steel 6, enabling the top rod 23 to be more smoothly pressed into the top groove when the bottom plate 2 rotates. The top rod 23 compresses the spring 24, and at the same time the top rod 23 abuts against the surface of the threaded sleeve 5. The rubber head increases the friction between the top rod 23 and the threaded sleeve 5, thereby fixing the threaded sleeve 5 and the bottom plate 2. Subsequently, when the operator rotates the shaft rod 4, the bottom plate 2 can be driven to rise and fall.

[0036] The specific implementation principle of this application is as follows: When it is necessary to fix the threaded rod to the bottom plate 2, the top plate 1 and the template 7 are fixed through the bolt 31 and the nut 32. Then the bottom plate 2 is rotated so that the bottom plate 2 and the top plate 1 clamp the angle steel 6 on both sides. At this time, the top rod 23 abuts against the surface of the threaded sleeve 5, fixing the threaded sleeve 5 and the bottom plate 2. Then the knob 41 is rotated to rotate the shaft rod 4, thereby driving the top plate 1 and the bottom plate 2 to clamp the angle steel 6, thereby strengthening the angle steel 6, making it more convenient for the worker to process the angle steel 6.

[0037] This specific embodiment is only an explanation of this application, and it is not a limitation of this application. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of this application, it is protected by the patent law.
