Description

Technical Field

[0001] The utility model relates to the technical field of highway reinforcement devices, and specifically relates to a highway pavement base reinforcement device. Background Technique

[0002] When the inner base of a highway is in use, it is mostly laid with a surface layer formwork. In order to ensure the stability of the surface layer formwork, a reinforcement device needs to be used to reinforce the formwork of the roadbed.

[0003] For example, the publication number is: CN219604107U (named a pavement base and surface layer formwork reinforcement device), which includes a channel steel formwork, a fixing wire, and a fixing nail; the front end of the fixing wire can be clamped into the channel steel formwork, and corresponding through holes are opened on the side wall of the channel steel formwork. A corresponding first cross bar and a second cross bar are fixed at the front end of the fixing wire, and there is a gap between the first cross bar and the second cross bar. The side wall of the channel steel is located between the first cross bar and the second cross bar; the width of the through hole is greater than the lengths of the first cross bar and the second cross bar; the rear end of the fixing wire is fixedly connected to the fixing nail, and the fixing nail is fixed on the roadbed or the cement stabilized base. The front end of the fixing wire is clamped with the channel steel formwork, and through the structural setting of the first cross bar and the second cross bar, the clamping can be conveniently realized; the other end of the fixing wire is fixed on the roadbed or the cement stabilized base; that is, the inner side reinforcement is adopted in this device; when the mixture is paved and compacted, the mixture gives an inward pulling force to the channel steel formwork through the fixing wire, and organizes the formwork to move outward, so as to ensure the reinforcement effect.

[0004] The above reinforcement device reinforces the roadbed formwork through the provided clamping mechanism on the inner side. However, since the thicknesses of most roadbed formworks are of different sizes, the clamping structure cannot be adapted and adjusted, resulting in the problem that different roadbed formworks cannot be reinforced. For this reason, we provide a highway pavement base reinforcement device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a highway pavement base reinforcement device to solve the problem that the existing reinforcement device reinforces the roadbed formwork through the provided clamping mechanism on the inner side. However, since the thicknesses of most roadbed formworks are of different sizes, the clamping structure cannot be adapted and adjusted, resulting in the problem that different roadbed formworks cannot be reinforced as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A highway pavement base reinforcement device includes a side baffle clamping seat. Two mounting hole plates are integrally formed on the front end face of the side baffle clamping seat, and a threaded linkage rod is arranged in the central groove position of the side baffle clamping seat;

[0007] It further includes:

[0008] The top pressing plate is arranged above the threaded linkage rod, and a through-guiding screw hole is arranged at the position where the threaded linkage rod penetrates through the side blocking clamping seat. A connecting shaft is integrally formed at the upper end of the through-guiding screw hole;

[0009] The assembly connecting grooves are arranged on the outer walls on both sides of the side blocking clamping seat, and an assembly connecting block is installed inside two adjacent assembly connecting grooves. The two side blocking clamping seats are fixedly connected in combination through the assembly connecting block;

[0010] The abutting clamping plate is arranged below the top pressing plate, and a limiting sliding block is integrally formed at the upper end of the abutting clamping plate. Inner sliding grooves and limiting sliding grooves are arranged at the sliding connection positions between the limiting sliding block and the top pressing plate. Both the inner sliding grooves and the limiting sliding grooves are of an integral structure with the top pressing plate;

[0011] The return spring is arranged inside the inner sliding groove, and spring discs are integrally formed at both ends of the return spring.

[0012] Preferably, two guiding insertion columns are welded at the bottom of the top pressing plate. Guiding inner grooves are arranged at the guiding connection positions between the two guiding insertion columns and the side blocking clamping seat. Both the two guiding inner grooves are of an integral structure with the side blocking clamping seat.

[0013] Preferably, an inscribed circular groove is arranged at the rotational connection position between the connecting shaft and the top pressing plate. The inscribed circular groove is of an integral structure with the top pressing plate. A bearing seat is arranged inside the inscribed circular groove. The connecting shaft is rotationally connected with the inscribed circular groove through the bearing seat.

[0014] Preferably, a bottom end disc is integrally formed at the other end of the threaded linkage rod. The size of the bottom end disc is larger than the caliber of the through-guiding screw hole.

[0015] Preferably, a turning handle is arranged on the outer wall of one side of the bottom end disc. The turning handle is of an integral structure with the bottom end disc.

[0016] Preferably, a positioning shaft disc is integrally formed at one end of the connecting shaft. The size of the positioning shaft disc is larger than the caliber of the bearing seat.

[0017] Preferably, the two spring discs are respectively welded and fixed to the outer wall of one side of the limiting sliding block and the inner wall of one end of the inner sliding groove.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] The utility model installs the side stopper holders to the positions on both sides of the highway roadbed, and can select a plurality of side stopper holders to be arranged in sequence for use according to the length of the highway roadbed. Two adjacent side stopper holders are connected and fixed by installing an assembly connecting block in an assembly connecting groove, and then the bottom end plate is reversed to drive the top pressure plate to be raised and lowered, so that the top pressure plate is adjusted to the edge position of the pressing roadbed template. Under the action of the top thrust of the reset spring, the abutting card plate abuts against the edge position of the roadbed template, thereby limiting the displacement of the roadbed template and achieving the purpose of reinforcing the roadbed template. The utility model overcomes the problem that the existing reinforcement device reinforces the inner side of the roadbed template by means of a clamping mechanism, but since the thickness of the roadbed template is mostly different in size, the clamping structure cannot adapt to the adjustment, resulting in the inability to reinforce different roadbed templates.

According to the length of the highway roadbed, multiple side stopper holders can be selected and arranged in sequence for use. Two adjacent side stopper holders are connected and fixed by installing an assembly connecting block in the assembly connecting groove. Then the bottom end plate is reversed to drive the top pressure plate to be raised and lowered, so that the top pressure plate is adjusted to the edge position of the roadbed template. Under the action of the top thrust of the reset spring, the abutment plate abuts against the edge position of the roadbed template, thereby limiting the displacement of the roadbed template.

[0034] See also Figure 3 Two guide pins 6 are welded at the bottom of the top pressure plate 2, and guide inner grooves 14 are provided at the guide connection positions between the two guide pins 6 and the side block holder 1. The two guide inner grooves 14 are an integral structure with the side block holder 1.

Under the action of the top thrust of the reset spring 13, the abutment plate 5 abuts against the edge position of the roadbed template, thereby limiting the displacement of the roadbed template and achieving the purpose of reinforcing the roadbed template. The side block holder 1 is fixed and grounded by installing the grounding bolt in the mounting hole plate 4 to complete the use of the highway pavement base reinforcement device.
