Assembly type prefabricated stair hoisting hanger

Abstract

The invention relates to an assembly type prefabricated stair hoisting hanger, which consists of an angle steel bracket, a steel wire rope, a basket screw and a hoisting point connecting piece, the angle steel bracket adopts angle steel to be welded into a rectangular structure, the length and the welding size of the angle steel are determined according to the lifting point position of the prefabricated stair, and four corners of the angle steel bracket are drilled; the upper end of the steel wire rope is connected with the lifting hook, and the lower end of the steel wire rope penetrates through a hole in the angle steel support and then is connected with the upper end of the turnbuckle, and the lower end of the turnbuckle is connected with the lifting point connecting piece through the steel wire rope. The turn buckle screw is composed of round steel, steel sleeves and a screw, the two ends of the round steel are welded to the two steel sleeves, the welding interval angle of the round steel is 120 degrees, the screw penetrates through the steel sleeves at the two ends, one end of the screw is welded to a round hanging ring, the hanging rings at the two ends of the turn buckle screw are connected with the steel wire rope, and the screw penetrating through the steel sleeves at the two ends is turned in a positive and negative mode. The hanging bracket can ensure that the prefabricated staircase can be accurately positioned and quickly mounted in the hoisting process, and mounting deflection and deviation are avoided.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to the hoisting of a professional assembled staircase for house construction, specifically, a hoisting bracket for an assembled prefabricated staircase. Background technique: [0002] In recent years, under the active promotion of the national construction industrialization and housing industrialization policies, prefabricated buildings have been widely used in housing construction. The prefabricated staircase is an important part of the prefabricated integral structure. Compared with the cast-in-place staircase, it has the advantages of less on-site wet work, short construction period, low cost, energy saving and environmental protection. However, in actual construction, the installation of prefabricated stairs often fails to meet the standards, such as the deviation of the installation of the stair treads, insufficient shelving length, etc., which has a certain impact on the ...

Problems solved by technology

However, in actual construction, the installation of prefabricated stairs often fails to meet the standards, such as the deviation of the installation of the stairs, the insufficient length of the shelving, etc., which has a certain impact on the on-time acceptance of the sub-projects and the construction period of the entire project.
