Description

Technical Field

[0001] The utility model belongs to the technical field of road and bridge construction, and specifically relates to a road and bridge construction supporting structure. Background Art

[0002] In the construction process of modern roads and bridges, the support system of the cap beam is particularly important for the safety, efficiency and quality of the construction. The currently widely used cap beam support method is the hoop method, that is, installing hoops on the outside of the pier, supporting the I-beam through the hoops, and then setting up a support frame above the I-beam for cap beam construction, using strong static friction to provide support. Since all the loads of the cap beam construction are supported by the hoops, the stable fit between the hoops and the pier and the tightness stability of the hoops are particularly important. The fault tolerance rate of a single hoop is low. Once the hoop is loose, the cap beam is at risk of sinking and collapsing at any time. Therefore, we need to make improvements based on the existing hoops to increase the support strength and stability of the hoops. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a road and bridge construction support structure to solve the problem that since all the loads of the cap beam construction are supported by the hoop, the stable fit between the hoop and the pier and the tightness stability of the bolts of the hoop are particularly important, and the fault tolerance rate of a single hoop is low. Once the hoop is loose, the cap beam is at risk of sinking and collapsing at any time. Therefore, we need to make improvements on the basis of the existing hoop to increase the supporting strength and stability of the hoop.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows: a road bridge construction support structure, including a pier column, a clamp assembly mechanism is arranged on the upper side of the pier column, an I-beam is symmetrically arranged on the upper side of the clamp assembly mechanism, the clamp assembly mechanism includes a clamp 1, a clamp 2, a semicircular ring 1, a semicircular ring 2, a reinforcement component, a fixing block, a connecting rod, a limiting rod, a nut and a plug-in hole, the clamp 1 and the clamp 2 are both sleeved on the outer side of the pier column, the clamp 1 is arranged on the upper side of the clamp 2, the I-beam is symmetrically arranged on the upper side of the clamp 1, and the lower side of the clamp 1 is symmetrically fixed A semicircular ring 1 is fixedly provided, and a semicircular ring 2 is symmetrically fixedly provided on the upper side of the hoop 2, and the semicircular ring 1 and the semicircular ring 2 are symmetrically sleeved on both sides of the pier, and a reinforcement component is provided between the semicircular ring 1 and the semicircular ring 2 on both sides, and the reinforcement component includes a reinforcement rod, a bolt, a pressure block, a structural arc rod, a plug-in rod, a movable groove, a pressure roller and a blocking block. The reinforcement rods are evenly arranged between the semicircular ring 1 and the semicircular ring 2, and bolts are equidistantly provided on the side of the reinforcement rod away from the pier, and the bolts penetrate the reinforcement rod and are rotatably provided with a pressure block, and the pressure block is provided close to the outer side of the pier.

[0005] The beneficial effects of the utility model are as follows: both the first and second clamps are sleeved on the outside of the pier column, an I-beam is set up on the upper side of the first clamp, the first clamp provides direct support for the construction of the cap beam, and the second clamp provides support for the first clamp through the reinforcing rod of the reinforcing assembly on the lower side, thereby increasing the stability of the support of the first clamp, and at the same time, the bolts are tightened, and the bolts push the pressure block to press the outer side of the pier column to increase the friction with the outer side of the pier column, thereby increasing the static friction between the entire clamp combination mechanism and the pier column. Compared with a single clamp, the present device has a higher fault tolerance rate and better strength and stability for supporting the construction of the cap beam.

[0006] In order to increase the structural strength of the reinforcement rod;

[0007] As a further improvement of the above technical solution: structural arc rods are arranged equidistantly between the reinforcing rods.

[0008] The beneficial effect of this improvement is that structural arc rods are arranged at equal distances between the reinforcing rods, so as to combine the reinforcing rods into a whole and increase the structural strength of the reinforcing rods.

[0009] In order to facilitate the maintenance and replacement of the structure of the clamp assembly mechanism;

[0010] As a further improvement of the above technical solution: plug-in holes are equidistantly provided between the semicircular ring 1 and the semicircular ring 2, plug-in rods are provided on the upper and lower sides of the reinforcing rod, and the plug-in rods are plugged with the semicircular ring 1 and the semicircular ring 2 through the plug-in holes.

[0011] The beneficial effect of this improvement is that the plug-in rod is plugged into the semicircular ring one and the semicircular ring two through the plug-in hole, which facilitates the disassembly and replacement of the reinforcement component during installation and use, thereby facilitating the maintenance and replacement of the component structure of the clamp combination mechanism.

[0012] In order to produce an emergency braking effect between the clamp assembly mechanism and the pier column;

[0013] As a further improvement of the above technical solution: a movable groove is opened on the side of the pressure block close to the pier, a pressure roller is rotatably arranged on the inner side of the movable groove, the pressure roller is arranged perpendicular to the pier, a blocking block is arranged on the lower side of the pressure roller, a side of the blocking block close to the pier is tangent to the outer periphery of the pressure roller, and the pressure roller and the blocking block are both arranged close to the outer side of the pier.

[0014] The beneficial effect of this improvement is as follows: a pressure roller and a blocking block are provided, and when the reinforcing component has a downward tendency under pressure, the pressure roller has a downward tendency due to friction, thereby driving the blocking block to press tightly against the outer side of the pier column. To a certain extent, the greater the downward pressure trend, the stronger the friction between the blocking block and the pier column, so that when the clamps 1 and 2 are accidentally loosened, an emergency braking effect is generated between the clamp assembly mechanism and the pier column, thereby preventing the clamp assembly mechanism from falling directly and losing its support and blocking effect on the I-beam.

[0015] In order to restrict the I-beam;

[0016] As a further improvement of the above technical solution: a fixing block is provided on one side of the semicircular ring that is away from each other, a connecting rod is provided on both sides of the fixing block, a limiting rod is sleeved on one side of the connecting rod that is away from each other, the limiting rod is provided on one side of the I-beam that is away from each other, nuts are provided on both sides of the limiting rod, and the nuts are threadedly connected to the connecting rod.

[0017] The beneficial effect of this improvement is that the limiting rod is provided to limit the I-beam and prevent the I-beam from falling off from the side and leaving the clamp one.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

Compared with a single clamp, the present device has a higher fault tolerance rate and better strength and stability for supporting the cap beam construction. Structural arc rods 254 are equidistantly arranged between the reinforcing rods 251.
