The bracket enables the hinge support to be installed by utilizing the lifting bracket to complete three indexes of structural support, increasing the lower hanging point and increasing the height difference of the upper hanging point and the lower hanging point, and utilizes the laser plumb gauge to control the axis deviation in the installation process, and the hinge support can be hung by matching with the chain block.

Description

Bracket for assisting hanging and installing of hinged support

Technical Field

The utility model relates to the technical field of construction of steel structures, in particular to a bracket for assisting hanging and mounting of a hinged support.

Background

The sliding support has the characteristics of simple structure, large bearing capacity, strong adaptability, long service life and the like, and is widely used for bridge engineering. In recent years, along with rapid development of construction technology, construction methods are more and more diversified, and a pushing method and a sliding method are widely applied to bridge construction, and in order to ensure smooth progress of the pushing construction process, a hinged support is usually installed after a main structure is pushed into place.

For hanging construction, two methods of direct hanging and jacking installation are generally available.

1. The method needs enough construction sites and hoisting spaces by adopting a hoisting mechanical direct hoisting method, and the construction environment of the hoisting equipment is generally limited and has poor practical operability.

2. The lifting construction installation is adopted, and the hinged support has the characteristics of heavier weight, small volume and the like in construction, so that the lifting installation cannot be directly carried out by manpower, lifting equipment and a large amount of auxiliary materials are needed, and the safety and the construction efficiency are poor.

Disclosure of Invention

The utility model aims to overcome the defects and provides a method for realizing safe and efficient hanging and installing construction operation of a hinged support by combining a lifting bracket and lifting equipment.

In order to achieve the above object, the present utility model is achieved by:

the bracket for assisting hanging and mounting of the hinged support comprises the hinged support (3) and is characterized in that: the device also comprises a lifting chain block (1), a laser plumb aligner (2) and a lifting bracket (4), wherein an upper hook of the lifting chain block (1) is fixed at the upper part of the main structure, and a lower hook is connected with the lifting bracket (4); the laser plumb aligner (2) is arranged at the center of the hinged support (3) and is aligned with the cross center line at the bottom of the main body structure; the lifting bracket (4) comprises a base (41), lifting lugs (42), a grid (43), a limiting plate (44) and a rubber pad; the grid framework (43) is made of square tubes, the base is made of two steel tubes, the length of the base is required to be larger than the length or the width of the grid framework (43), lifting lugs are arranged at two ends of the base and used for the lower hanging point of the chain block (1); the method comprises the steps of placing a hinged support (3) on the upper part of a lifting bracket (4), connecting an upper lifting lug of the lifting bracket (4) with a lower hook of a chain block (1), then vertically lifting the lifting bracket (4) and the hinged support (3) to a designed elevation by the chain block (1), connecting the hinged support (3) with a main structure, and adjusting the axial position and the height of the hinged support (3) in an auxiliary manner through the chain block (1) in the connecting process; after the installation is completed, the lifting bracket (4) is put down and the other hinge supports (3) are reused and installed.

The bracket provided by the utility model can ensure that the hinge support can be mounted by utilizing the lifting bracket to complete three indexes of structural support, increasing the lower lifting point and increasing the height difference of the upper and lower lifting points, and can realize the mounting of the hinge support in a hanging way by utilizing the laser plumb aligner to control the axis deviation in the mounting process and matching with a chain block. Compared with the traditional installation process, the method has the following advantages:

1. the device has the advantages of simple structure and convenient use, can be repeatedly used for a plurality of times for the same type of hinged support, can be temporarily manufactured on a construction site, is made of common materials such as square tubes and angle steel, and has the characteristics of good stress performance, light weight and the like.

2. Compared with the traditional process, the construction method omits the use of large machinery, simplifies the construction process, and greatly improves and ensures the construction efficiency and the safety by combining the chain block with the lifting bracket.
