Problems solved by technology
In this way, the traditional construction process leads to inaccurate positioning of the steel keel in the formwork. During the installation and positioning process, it takes a long time to occupy crane resources. The construction project is time-consuming and laborious, and the construction efficiency is low.

Embodiment 1
[0029] Embodiment 1: as Figure 1-4 , a construction method for a long-span steel concrete beam, comprising the steps of:
[0030] 1) Install multiple sets of scale lifting pipe devices on the bottom form of the steel concrete steel beam to be installed, and two scale lifting pipe devices are arranged opposite to each other to form a set of support units;
[0031] The lifting pipe device with a scale scale used in the construction includes a lifting pipe body 1, and two chute 2 are vertically opened on the side walls of the opposite sides of the lifting pipe body 1, and the chute 2 runs through the jacking pipe body 1. The upper end of the pipe body 1; a jacking beam 3 is horizontally provided in the chute 2, and the jacking beam 3 passes through the chute 2 and is connected to it by sliding fit;
[0032] 2) Use a crane to hoist the shaped steel beam to between the two graduated ruler lifting pipe devices, and clamp the graduated ruler lifting pipe device to the upper flange ...

The invention discloses a construction method of a large-span profile steel reinforced concrete beam, which comprises the following steps that 1) a plurality of groups of scale guiding rule jacking pipe devices are installed on a bottom form of a to-be-installed profile steel reinforced concrete profile steel beam, and two scale guiding rule jacking pipe devices are oppositely arranged to form a group of supporting units; 2) the profile steel beam is hoisted to a position between the two scale guiding rule jacking pipe devices by adopting a crane, and an upper flange plate of the profile steelbeam is clamped by the scale guiding rule jacking pipe devices; 3) the scale guiding rule jacking pipe devices are jacked by adopting a jack, and the profile steel beam is driven to move to a specified position; 4) binding and welding are conducted on a bottom rib and a surface rib of the profile steel beam; 5) stirrups and stirrup lower cushion blocks are placed; and 6), after the crane is unloaded, a formwork is supported, and concrete is poured. For installation of a large-span profile steel reinforced concrete beam, the very good positioning, supporting and fixing effects are achieved, the structure is simple, a jacking pipe can achieve the very good supporting effect, the jacking position can be fixed according to needs, the construction efficiency is improved, and construction resources are saved.
Description
technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a construction method of a large-span steel concrete beam. Background technique [0002] With the continuous improvement of construction technology, the form of building structure is becoming more and more complex, and steel concrete structures are more and more used in high-end buildings. The structural forms to solve large spans are: steel structure, prestressed concrete structure, steel concrete structure etc. Among them, the steel concrete structure can effectively reduce the cross-sectional area of the member and improve the mechanical performance of the member. In the steel concrete structural column, there is a composite structure of eight-shaped reinforced concrete clad with steel diagonal bracing. The structural components are dense and there are many connection nodes. It is a complicated subject for component positioning, node conne...
