Description

A guiding orientation device for prefabricated stair hoist and mount

Technical Field

The utility model relates to a wall body process of plastering, concretely relates to guiding orientation device for prefabricated staircase hoist and mount.

Background

The prefabricated staircase is prefabricated the shaping back at the mill with the stair, transports the job site after and installs, compares in traditional cast-in-place stair, need not to erect the template, also need not to water the maintenance, has solved the problem that cast-in-place stair technology is loaded down with trivial details, the efficiency of construction is low, very big reduction the time limit for a project, consequently adopted by more and more engineering.

Generally, the installation of the prefabricated staircase is realized by adopting the following steps: pouring and prefabricating a stair interface, maintaining, arranging a mortar leveling layer on the stair interface, hoisting the prefabricated stair, correcting the prefabricated stair, fixing the prefabricated stair and the stair interface, and protecting a finished product. In the above-mentioned work progress, there is the precision not enough when hoist and mount prefabricated staircase, is difficult to guarantee the problem of the accuracy of the plane position and the elevation of stair installation. After the elevator is hoisted in place, the elevator is generally finely adjusted by a crowbar, and the edges and corners of the stairs are easily damaged. The prefabricated staircase is generally made of fair-faced concrete, decoration is not performed on the prefabricated staircase, once edges and corners are damaged, the prefabricated staircase is not easy to repair, and the appearance is affected by color difference.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide one kind can be to prefabricated staircase accurate positioning, simultaneously, can not influence prefabricated staircase outward appearance, and prefabricated staircase location and install swift a guiding orientation device for prefabricated staircase hoist and mount.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a guide positioning device for hoisting a prefabricated staircase is fixed on a staircase interface and is characterized by comprising a positioning steel plate and a staircase guide plate detachably connected to the positioning steel plate, wherein the positioning steel plate consists of a vertically arranged angle steel and a horizontal foot plate connected to the outer wall of one side edge or two side edges of the lower end of the angle steel; the stair deflector is vertical setting, comprises last guide part and lower connecting portion, it is L shape to go up the guide part, and the both sides limit of going up the guide part corresponds with the both sides limit of angle steel respectively, and connects on the location steel sheet through lower connecting portion detachably to form the guide angle of an L shape after being connected with the angle steel. Like this, when using, through the unwrapping wire after measuring, can confirm the position of prefabricated staircase on the stair interface, then according to unwrapping wire position, can fix the location steel sheet on the stair interface, fix the stair deflector on the location steel sheet at last, form the guide angle of an extending direction together with the angle steel of location steel sheet to make prefabricated staircase corner correspond the back with this guide angle, can follow this guide angle and move down to accurate position, realize the disposable location of prefabricated staircase. The foot plate on the positioning steel plate is convenient for being fixedly connected with the stair interface and can be erected on the stair interface before being fixed. The height of angle steel can be prolonged to the stair deflector that sets up, and can select the stair deflector of different vertical height according to the hoist and mount condition.

Further, connect down and set up the projection at last guide part both sides board lower extreme for a plurality of intervals, the projection is vertical setting, and equal interval is equipped with a plurality of pilot holes that are vertical setting on angle steel both sides board, projection and pilot hole one-to-one set up, and projection and each pilot hole tight fit. Like this, fixed together through the mode of socket joint between stair deflector and the location steel sheet, the assembly methods is simple, and the structure is also firm.

Further, all overlap on every projection and have a rubber cylinder, the rubber cylinder can warp under the extrusion of pilot hole pore wall, and the external diameter is supreme crescent from down. Like this, the rubber cylinder that sets up can effectively increase the steadiness between projection and the pilot hole, and the change of external diameter can be convenient for the inserting of rubber cylinder.

Furthermore, the wall thickness of the upper guide part is gradually reduced from bottom to top, so that a slope surface is formed on the inner side of the upper guide part. Like this, the direction angle that forms between the angle steel inner wall of stair deflector and location steel sheet can form the guide to prefabricated stair transfer route, transfers appointed position gradually, and it is more convenient when slope makes transferring.

Further, the longitudinal height of the positioning steel plate is 200mm-300 mm. Therefore, the positioning steel plate is small in height, and the foot plate can stand conveniently.

Furthermore, the horizontal foot plate is L-shaped and is integrally formed with the angle steel. Thus, the positioning steel plate is integrally formed and has good strength. After the foot plate is L-shaped, the grounding area is large, and the stability is better.

Furthermore, a plurality of threaded holes or through holes are arranged on each side of the horizontal angle plate at intervals. Therefore, when the foot plate is fixed, the bolt can penetrate through the through hole and then is fixedly connected with the stair interface.
