Description

Technical Field

[0001] This application relates to the field of bridge construction technology, and in particular to an auxiliary support device, bridge construction equipment and construction method. Background Technology

[0002] Steel-concrete composite beams are a new type of structural form developed based on steel and reinforced concrete structures. They primarily rely on shear connectors between the steel beams and reinforced concrete flanges to resist uplift and relative slippage at the interface, allowing them to function as a unified whole. Combining the advantages of both steel and reinforced concrete beams, steel-concrete composite beams are finding increasingly widespread application in bridge construction in my country.

[0003] The main construction approach for steel-concrete composite beams is to manufacture I-beams in sections at the factory, then set up an assembly yard on site, assemble the steel beam segments and crossbeams on the assembly platform according to the manufacturing alignment and camber, and then use the assembled steel beams as the bottom formwork support to erect the formwork and cast the bridge deck in place for stacking; after stacking, the crossbeams between each beam are removed, and then each steel-concrete composite beam is transported by a beam transport trolley and then erected by a bridge erecting machine.

[0004] During the construction of steel-concrete composite beams, the beams are typically prefabricated in a factory, transported to the bridge construction site, and then hoisted onto the bridge piers using a bridge erecting machine. During this process, ropes are used to position the steel-concrete composite beams. However, due to the significant weight of the beams, the positioning mechanisms are prone to tipping over due to the weight, affecting construction and potentially posing safety hazards to workers and property.

[0054] As shown in the figure, the embodiments of the present invention provide, in order to solve the above-mentioned technical problems, the first objective of the present invention is to provide an auxiliary support device; the second objective of the present invention is to provide a bridge construction equipment; and the third objective of the present invention is to provide a construction method.

[0055] The technical solution provided by this invention is as follows:

[0056] An auxiliary support device for auxiliary support when installing a panel on a cable tray body A, comprising a base 1, a displacement driving mechanism 2, a support seat 3, and a support assembly 4;

[0057] The base 1 is mounted on the cable tray body A;

[0058] The support base 3 is mounted on the cable tray body A, and the support base 3 is provided with a movable push plate 31 and a rotatable docking rod 32; the docking rod 32 is provided with two threaded sections 321 with opposite directions of rotation, and each threaded section 321 is provided with a threaded slider 34 that is threadedly engaged with it; each threaded slider 34 is provided with at least one inclined tie rod 33, one end of the inclined tie rod 33 is hinged to the threaded slider 34, and the other end is hinged to the push plate 31;

[0059] The support assembly 4 includes two connecting seats 41 and two support rods 42. The two connecting seats 41 are respectively connected to two threaded sliders 34. One end of the two support rods 42 is hinged to each other, and the other end is respectively hinged to a connecting seat 41.

[0060] The displacement driving mechanism 2 connects the base 1 and the push plate 31, and drives the push plate 31 to move along the height direction.

[0061] The rollover occurred due to the significant weight of the composite beam. The applicant discovered that the main increase in weight during bridge hoisting was in the areas where concrete was added. Therefore, the applicant provides an auxiliary support device pre-installed on the steel beam. This changes the traditional construction method where the concrete slab needs to be installed before hoisting the bridge frame. Instead, the steel beam section without the concrete slab is hoisted first. After the steel beam is hoisted, the auxiliary support device assists in the installation of the concrete slab. After concrete pouring, the concrete slab is fixed, and then the auxiliary support device is removed. The auxiliary support device provided in this application allows for hoisting only the steel beam without the weight of the concrete, significantly reducing the hoisting weight and minimizing the risk of rollover.

[0062] Specifically, the auxiliary support device provided in this application includes a base 1, a displacement driving mechanism 2, a support seat 3, and a support assembly 4. The base 1 is mounted on the cable tray body A. The support seat 3 is mounted on the cable tray body A, and a movable push plate 31 and a rotatable connecting rod 32 are provided on the support seat 3. The connecting rod 32 has two threaded sections 321 with opposite directions of rotation, and each threaded section 321 is provided with a threaded slider 34 that is threadedly engaged with it. Each threaded slider 34 is provided with at least one inclined tie rod 33, one end of which is hinged to the threaded slider 34, and the other end is hinged to the push plate 31. The support assembly 4 includes two connecting seats 41 and two support rods 42. The two connecting seats 41 are respectively connected to the two threaded sliders 34, and one end of the two support rods 42 is hinged to each other, and the other end is respectively hinged to one connecting seat 41. The displacement driving mechanism 2 connects the base 1 and the push plate 31 and drives the push plate 31 to move along the height direction. In use, the base 1 and the support seat 3 are fixed to the cable tray body A respectively. Then, the displacement drive mechanism 2 drives the push plate 31 to move downward. Since the inclined rod 33 is hinged to the push plate 31 and the threaded slider 34, and the threaded slider 34 is threadedly engaged with the connecting rod 32, the distance between the push plate 31 and the connecting rod 32 changes as the force is transmitted, causing the connecting rod 32 to rotate. This causes the threaded slider 34 to move along the axis of the connecting rod 32. Since the two threaded sections 321 have opposite directions of rotation, the two threaded sliders 34 move in opposite directions and approach each other, causing the connecting seat 41 to also approach each other. The hinged position of the support rod 42 and the connecting seat 41 also gradually approaches, so that the hinged end of the support rod 42 is lifted up and becomes a fulcrum for supporting the panel to be installed. By providing a fulcrum through multiple auxiliary support devices, the panel to be installed is supported. This allows the panel to be installed after the cable tray body A is in place, and the operation is simple.

[0065] Specifically, the push rod 23 and the cam cooperate to form a cam-cam structure, and the displacement power source 22 is set as a rotary drive (such as a motor, rotary cylinder, etc.). The push rod 23 drives the cam to rotate under the drive of the displacement power source 22, thereby causing the rotating rod 221 to move along the height direction. By controlling the angle of rotation of the cam, the push rod 23 can be raised or lowered.

[0066] Further preferably, the base 1 is also provided with a base support block, and a limiting block is provided above the base support block. The limiting block has a through hole for the rotating rod 221 to pass through.

[0069] Specifically, the positioning seat 21 is slidably mounted on the slide rod 24, allowing the positioning seat 21 and its connected displacement power source 22 to translate. This enables the movement of the aforementioned structures during the installation and adjustment of the base 1 and support 3. After adjustment, the positioning seat 21 is fixed; fixing can be achieved using conventional methods in the art, such as pins.

[0070] In addition, the outer edge of the base 1 is provided with a guard edge 11, the axis of which is parallel to the power output direction of the displacement power source 22, thus playing a protective role.
