Problems solved by technology

The forms of connecting wall parts we often use include: fastener connection, welding, bolt connection, etc. The fastener connection is to use steel pipes to connect and fix structural columns or walls, but the connection walls must be repeatedly removed and modified during the construction of the external window Fasteners are labor-intensive; welded connections are pre-embedded steel plate embedded parts in the structure, and steel pipes for wall parts are welded on it, but gas welding needs to be cut from the welded steel pipes when dismantling, and the operation is cumbersome; bolted connections are structurally pre-installed. Burying bolts or drilling holes on the wall to make wall rods in

Embodiment 1

[0063] At the same time, refer to Fig. 2 and Fig. 3. Use oxyacetylene cutting equipment, punching machine, welding machine, welding rod, etc. to weld the short steel pipe 3 of Φ48mm and 600mm in length on the 200×100×10mm steel plate embedded part 1, and punch two Anchor holes pass through chemical anchor bolts 2 that have been anchored on steel structures and concrete building exterior walls 7, and are tightened and fixed by the nuts of connectors 4;

[0064] (11) Connect with the wall rod

[0065] Connect the short steel pipe 3 to the wall bar 601 of the existing floor fastener steel pipe scaffold 6 through the existing single or multiple fasteners 5; When tightening the steel pipe 3, the minimum distance between the openings is less than 5mm, and no damage shall occur when the bolt tightening torque reaches 65N·m;

Embodiment 2

[0067] Referring to Fig. 4 and Fig. 5, when the scaffold 6 needs to be partially unloaded, the size of the steel plate embedded part 1 with the short steel pipe 3 can be increased to 200×200×10mm, and a steel bar made of HPB235 grade and Φ18mm can be added. The lifting ring 8 is welded with the steel plate embedded part 1, the height and length of the weld seam are determined by calculation, and the lifting ring 8 is unloaded through the clamp 9 and the steel wire rope 10 and the scaffold 6;

[0068] (12) Acceptance of wall parts

[0069] a) Check whether the scaffolding construction plan is declared and approved according to the regulations;

[0070] b) Check whether the spacing and position of the setting points of the connecting wall parts are consistent with the plan;

[0071] c) Check whether the processing of post-embedded parts is qualified, and the qualification certificates of various materials;

[0072] d) Check whether the pull-out test results of the chemical bol...

Abstract

The invention relates to an erection construction method for a rearmounted pre-embedded type fastener to wall, wherein a chemical anchor widely applied to steel structure and concrete is anchored on the wall or post of a building, a steel plate embedded part with a short steel pipe is fixed on the chemical anchor, and the short steel pipe on the steel plate embedded part is connected with the a scaffold wall rod. The method comprises the following steps: (1) determining the chemical anchor; (2) placing a chemical anchor position line; (3) processing outer wall surface base material; (4) drilling holes the base material; (5) cleaning the holes; (6) putting a drug tube in; (7) screwing in a screw; (8) curing; (9) pull-out testing; (10) installing a rearmounted embedded part; (11) connecting with a wall rod and (12) acceptance checking the wall rod. The method is easy to operate, the anchoring force is reliable, the construction cost is low, the efficiency is high, convenient for detaching and turnover for many times, the safe use of a scaffold and the normal use and security of the inside of a building are effectively ensured; the damage to the original building structure is little, and the method can be widely applied to a floor type scaffold higher than 24 meters in rebuilding or refitting engineering, and the anchoring of steel structure and concrete having a concrete strength less than C20.

Description

technical field [0001] The invention belongs to the field of building construction, and relates to a construction method for using post-embedded pre-embedded connecting wall parts and floor-standing fastener steel pipe scaffolds in building reconstruction or renovation projects. Background technique [0002] The connecting wall structure of floor-standing fastener steel pipe scaffolding, referred to as "connecting wall parts", is generally divided into rigid connecting wall structure and flexible connecting wall structure. For rigid wall parts. The forms of connecting wall parts we often use are: fastener type connection, welding, bolt connection, etc. The fastener type connection is to use steel pipe to connect and fix the structural column or wall, but it is necessary to repeatedly dismantle and modify the connecting wall during the construction of external windows. Fasteners are labor-intensive and labor-intensive; welding connection is to embed steel plate embedded part...
