Embodiment Construction

[0035] Examples see Figure 1-8 As shown in the assembly type prefabricated floor connector for steel structure buildings, the prefabricated floor 1 is placed on the I-beam 4, and the prefabricated floor 1 is distributed with upper and lower rows of longitudinal steel bars 2 at intervals, and the two ends of the longitudinal steel bars 2 pass through Exposed steel bars are formed on both ends of the prefabricated floor slab 1 . The prefabricated floor 1 may have a width of 0.6-1.0m and a thickness of 90-130mm.

[0036] The ends of the exposed steel bars at both ends of the prefabricated floor slab 1 are steel bar piers 5 equipped with a backing plate 6, or the exposed steel bars at one end of the prefabricated floor 1 are steel bar piers 5 equipped with a backing plate 6, and the other end The extruded sleeve 7 is installed at the end of the exposed steel bar.

[0037] The I-beam 3 is vertically welded with a strip-shaped steel plate 4 along the entire length of the top surf...

Abstract

The invention discloses an assembly type prefabricated floor slab connecting piece for a steel structure building and a mounting method thereof. Exposed reinforcement end parts at the two ends of a prefabricated floor slab are both reinforcement pier heads of which the end parts are additionally provided with base plates, or the exposed reinforcement end part at one end of the prefabricated floor slab is a reinforcement pier head of which the end part is additionally provided with a base plate, and the exposed reinforcement end part at the other end is provided with an extrusion sleeve; an I steel beam is vertically welded with a strip-shaped steel plate in the full length along a top surface; reinforcement positioning grooves are spaced in the strip-shaped steel plate in the length direction; the prefabricated floor slabs on the two sides of the strip-shaped steel plate on each I steel beam are arranged in a staggering manner; the exposed reinforcements of the prefabricated floor slabs on the two sides of the strip-shaped steel plate are placed in the reinforcement positioning grooves in a mutual staggering manner and are fixed to the strip-shaped steel plate through the reinforcement pier head or the extrusion sleeve of which the end part is additionally provided with the base plate. The connecting piece is extremely convenient to mount, the construction processes can be greatly reduced, the anchoring time of the prefabricated floor slab and the steel beam is saved, and the anchoring strength of the floor slab can be obviously improved. The connecting piece can be widely applied to connection between the prefabricated floor slab and the steel beam in an assembly type steel structure building.

Description

technical field [0001] The invention relates to the field of prefabricated steel structure buildings, in particular to a connector of a prefabricated floor slab and a steel beam and an installation method thereof. Background technique [0002] At this stage, the floor slab of the steel structure building system mainly adopts cast-in-place concrete structure. After the steel beam is installed, the formwork is supported, the steel bars are bound, and the concrete is poured. After the concrete reaches a certain strength, the next process of construction can be carried out. The speed of steel structure installation is greatly reduced. [0003] The existing prefabricated reinforced concrete floor slabs can be pre-processed and shaped in the factory, and then transported to the construction site for installation. The prefabricated floor slabs can greatly shorten the construction period and reduce the project cost. The anchorage performance of prefabricated slabs and steel structu...
