Stable supporting device for girder body

Abstract

The invention discloses a stable supporting device for a girder body. The stable supporting device comprises a set of supporting single parts or at least two sets of supporting single parts, wherein the two sets of supporting single parts are arranged side by side; each supporting single part comprises a base and an adjusting mechanism, and the base is used for bearing the girder body; the adjusting mechanism comprises at least one set of adjustable connection parts, the lower ends of the adjustable connection parts are movably arranged on the bases through connecting parts, and the upper ends of the adjustable connection parts are tightly attached to the girder body. According to the technical scheme, the stable supporting device for the girder body has the advantages that the quantity of the supporting single parts is selected according to the specific condition to meet the using requirement; each supporting single part comprises the base and the adjusting mechanism, the base is used for bearing the weight of the girder body, the adjustable connection parts are used for adjusting the contact position of the upper portion of the supporting device and the girder body, and on the condition that high supporting stability is guaranteed, the stable supporting device is concise in structure, light, and convenient to manufacture, deliver and use; the design of the bases leaves certain gaps between the lower portion of the girder body and the ground or other placing members, and the check of the girder body is facilitated.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a stable support device for a beam body. Background technique [0002] Prestressed concrete girder bridges (especially T-beams) have the characteristics of simple structure, clear force, material saving, convenient erection and installation, and large spanning capacity. my country's road traffic has played an important role. Its main advantages are as follows: First, it is a prefabricated structure with mature technology and relatively safe construction; second, it adopts prefabricated assembly, which can be factory-like construction, with short construction period and reliable quality. It is lighter than hollow slab bridges and can be used for larger span bridges. diameter, to overcome the shortcomings of the impact of multiple spans on the appearance; the third is to use a small cross-section during hoisting, and then pour wet joints to connect the steel bars of the...

Problems solved by technology

In the process of beam storage, due to the influence of the structure of the beam itself, in order to solve the problem of the stability of the beam storage, in engineering construction, it is generally simple to use logs to simply support the flange plate or the upper position of the web to solve the problem, but this kind of The method has the following defects: (1) the beam often overturns during storage, which easily leads to damage to the beam and causes unnecessary losses; (2) in order to ensure the quality of each beam erected, it usually takes more Each beam body is inspected. Due to the lack of special equipment or devices, most beam bodies have blind spots for inspection.
