Description
The application is a divisional application of an invention patent application with the patent application date of 2020, 10 and 13, and the patent application number of 202011090231.8, and the name of the invention is 'a prestressed steel-concrete composite beam anchor groove construction method'.
Technical Field
The invention relates to a construction technology of a prestressed steel-concrete composite beam, in particular to a sulfur mortar anchor groove precast block for constructing an anchor groove of a prestressed steel-concrete composite beam.
Background
The steel-concrete composite beam has the advantages of both a steel structure and a concrete structure, has obvious economic benefit and social benefit, and is increasingly widely applied to urban overpasses and building structures in China.
The prestress applied to the steel-concrete composite beam is generally applied after the bridge deck and the steel beam form a composite section, and the steel structure and the concrete on the whole section are under the action of the prestress, so that the stress of the pressed bottom plate of the steel structure is more unfavorable, and the prestress applied to the concrete is greatly reduced.
When prestress is applied to the combined prestressed girder, the bridge deck and the steel girder are in a separated state, and most of prestress is applied to the bridge deck. In the prior art, when a bridge deck slab of a post-combined prestressed composite beam is constructed by a cast-in-place method, generally, welding nails are uniformly arranged on a steel beam top plate in a positive bending moment area of a continuous beam to be connected with the bridge deck slab, group nails are adopted in a negative bending moment area to be connected, and prestressed steel beams are arranged in the bridge deck slab in the negative bending moment area to apply prestress. In order to ensure that the bridge deck in the hogging moment area can be separated from the steel beam when prestress is applied, an anchor groove (group nail hole) needs to be reserved when the bridge deck is poured, and after the prestress is applied, micro-expansion high-strength mortar is poured into the anchor groove to enable the bridge deck and the steel beam to be combined to form a combined structure so as to participate in later-stage stress of the structure. At present, the construction method of the anchor groove usually adopts a wooden template to erect the template on site to reserve the position of the group nail hole, and chisels off the wooden template after pouring the concrete of the bridge deck slab. By adopting the construction method, the reserved steel bar holes on the wood template are difficult to position, the steel bars are difficult to penetrate, and when the bridge deck concrete is poured, mortar can leak from the reserved steel bar holes on the template to the group nail holes, so that the construction quality is difficult to ensure; after pouring, the wooden formwork is difficult to take out, so that not only is a large amount of working hours needed for formwork removal, but also a small amount of sawdust is remained in the concrete and cannot be taken out, and the progress and the quality of the project are seriously influenced.
