Embodiment Construction

[0045] Attached to the following Figure 1-8 This application will be described in further detail.

[0046] refer to figure 1 , an existing renovation project is a circular frame structure. Four original structural columns 2 are distributed in an array at the bottom of the main beam 1 of the circular structure, and the original structural beams 3 are respectively connected between the opposite original structural columns 2. There are columns 4 to be pulled out at the intersections of the original structural beams 3, and now the columns 4 to be pulled out need to be cut off to increase the floor area.

[0047] The embodiment of the present application discloses a joist pulling column construction method. A joist pulling column construction method, comprising the following steps:

[0048] S1. Install hoop and steel beam: refer to figure 2 and image 3 , first install the hoop 5 on the four original structural columns 2, the hoop 5 includes an installation section 51 and a ...

Abstract

The present application relates to a joist pulling column construction method, comprising the following steps: S1, installing steel beams: installing a hoop on top of four original structural columns, connecting a steel beam at the end of the hoop, and extending the steel beam away from the end of the hoop To the position close to the column to be pulled out, and the steel beam is attached to the original structural beam; S2. Install the temporary support column: Install the temporary support column around the column to be pulled out, so that the temporary support column supports the steel beam; S3. Outsourcing steel plate: Cover the outer surface of the original structural beam with steel plates, and use chemical anchors to connect the steel plates to the original structural beams; S4. Cut the columns to be pulled out: After the support is stable, use cutting tools to cut off the columns to be pulled out; S5. Install cross steel beams : After cutting off the columns to be pulled out, install cross steel beams on the bottom surface of the intersection of the original structural beams; S6, inject steel glue: inject steel glue between the steel plate and the original structural beams; S7, remove the temporary support columns; S8, Measure the stress and deflection of composite beams. The present application has the effects of simple construction procedures and reduced workload.

Description

technical field [0001] The present application relates to the field of reconstruction construction, and in particular, to a construction method for pulling out joists. Background technique [0002] The joist pulling column is to remove the structural load-bearing column without dismantling or less dismantling the superstructure. Compared with the traditional large-lift cover transformation, the joist pulling-out method has the advantages of less impact on production and life, less impact on the original structure, short construction period and low cost, but the technical requirements are often very high in implementation. Security measures must be tight. [0003] At present, the underpinning steel support system generally adopted for joist pull-out column includes conventional steel tube fastener full-house scaffolding support, temporary reinforced concrete structural column support, and steel corbel steel support, etc., but in practical application, there are cumbersome pr...
