Abstract
The utility model discloses a sizing through connection device of a stairway provisional protective barrier. The sizing through connection device of the stairway provisional protective barrier comprises a platform upright, a corner connecting pipe, and a stairway rail, wherein the platform is formed by adopting a lower end of a metal pipe to be connected with a metal plate in a welding mode, and two metal straight pipes are symmetrically arranged on the middle portion and the top end portion of the metal pipe; the corner connecting pipe is welded by two metal pipe right angles, and one end of the corner connecting pipe is connected with one ends of four metal straight pipes; and one end of the stairway rail is connected with the other end of the corner connecting pipe. The sizing through connection device of the stairway provisional protective barrier has the advantages of being capable of realizing the connection of stairway adjacent side provisional rails while going up and down, guaranteeing reliable connection of a structure, being used repetitively, easy and convenient to operate, attractive, and practical.
Description
Technical field:
The utility model relates to a kind of regularization switching device of the temporary protection railing for the building construction process stair, can be used for adopting in work progress steel pipe scaffolding to the reliable connection of unguarded stair corner when interim safeguard protection railing is installed.
Background technology:
Building operations structure stage and two structures are in the stage at present, the temporary railing of stair generally adopts the mode of steel tube lapping, because each stair length differs, highly differs, many steel pipes need carry out brachymemma to be processed, caused the waste of material, and it is large to set up workload with steel tube fastener, is connected without reliable with structure, usually causes in the process of stair activity and topples.
The utility model content:
The problems referred to above that exist for solving prior art, the purpose of this utility model is the regularization switching device that proposes a kind of temporary protection railing of stair, it adopts the transition of column steel pipe, the telescopic connection of corner, hex bolts is fixed, and can realize the connection of stair activity adjacent side temporary railing, guarantee to be connected with the reliable of structure, and easy and simple to handle, both artistic and practical, and can reuse.
For achieving the above object, the utility model is achieved by the following technical programs:
The regularization switching device of a kind of staircase temporary protective railing of the present utility model, comprise the platform column, it adopts a metal tube lower end weld plate to be formed by connecting, and the position, the top of this metal tube and centre position are symmetrical respectively is welded with 2 metal straight pipes; The corner tube connector be welded by 2 metal tube right angles respectively, and an end of this corner tube connector is connected with an end of described 4 metal straight pipes respectively; Stair railing, the one end is connected with the other end of described corner tube connector.
As further feature of the present utility model, offer some apertures on described metal sheet, by expansion bolt, this platform column is connected with the landing structure.
As further feature of the present utility model, described corner tube connector is provided with some apertures, and WELD NUTS, by bolt, one end of this corner tube connector and an end of described metal straight pipe is connected and fixed, and an end of the other end and described stair railing is fixed.
As further feature of the present utility model, described metal material is steel.
Owing to adopting above technical scheme, the regularization switching device of a kind of staircase temporary protective railing of the present utility model, it adopts column tube transition, the telescopic connection of corner in order to replace original conventional use steel pipe scaffolding overlap joint etc. as the method for stair temporary armrest, hex bolts is fixed, can realize the connection of stair activity adjacent side temporary railing, guarantee to be connected with the reliable of structure, and easy and simple to handle, both artistic and practical, and can reuse.

The specific embodiment
Below in conjunction with specific embodiment, further set forth embodiment of the present utility model.Should be understood that these embodiment only to be used for explanation the utility model and be not used in restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
as Fig. 1, 2, shown in 3, the regularization switching device of a kind of staircase temporary protective railing of the present utility model, comprise the platform column, it adopts a metal tube lower end weld plate 1 to be formed by connecting, and the position, the top of this metal tube and centre position are symmetrical respectively is welded with 2 metal straight pipes 3, in the present embodiment, this metal straight pipe 3 adopts diameter 60mm, wall thickness 3.5mm, the steel pipe of height 1100mm, metal sheet 1 adopts 6 * 100 * 200 steel plate (offering the circular hole of two diameter 12mm on steel plate), be connected with landing structure 7 by M10 expansion bolt 2, 4 metal straight pipes 3 of column shaft welding are that 110 ~ 150mm is long, diameter 48mm, the building operations scaffold tubes of wall thickness 3.5mm,
The corner tube connector be welded by 2 metal tube 4 right angles respectively, and an end of this corner tube connector is connected with an end of 4 metal straight pipes 3 respectively; In the present embodiment, metal tube 4 adopts two diameter 60mm, wall thickness 3.5mm, and the short steel pipes right angle of long 150mm ~ 500mm is welded, and offers the aperture 8 of 1 ~ 4 diameter 14mm on short steel pipes, welds M12 nut 6 at this position, and the nut place is screwed into M12 bolt 5; Stair railing, the one end is connected with the other end of corner tube connector, adopt the building operations scaffold tubes of diameter 48mm, wall thickness 3.5mm in the present embodiment, scaffold tubes can be selected 1500mm, 1800mm, 2700mm, 3600mm equal length specification, can adopt two fasteners to carry out the colligation overlap joint when length is inadequate.
The utility model when mounted, at first the fixed platform column, insert stair railing in the corner tube connector afterwards, the corner tube connector other end is inserted on the connection short tube of platform column, tighting a bolt at last gets final product.
