Embodiment 1

[0023] like figure 1 As shown, the temporary rotating protective railings for the flat opening of the elevator shaft opening of civil construction houses include two protective railings 1, which are respectively installed on the outer sides of the elevator shaft opening 3 through rotating supports 2 and are connected to the elevator shaft opening 3 in rotation. , The rotating support 2 is provided with fixing holes, and installation holes are provided at the corresponding positions on both sides of the elevator shaft opening 3, and the rotating support is fixed at the elevator shaft opening 3 by using Φ6-Φ8mm expansion bolts.

[0024] In this embodiment, two rotating supports are respectively provided on both sides of the entrance 3 of the elevator shaft, so as to ensure that the protective railings are installed and fixed. The installation hole adopts electric hammer drill Φ8-Φ10mm, depth 60-80mm.

[0025] In this embodiment, the width of the protective railing 1 is determin...

Embodiment 2

[0041] The temporary rotating protective railing for the horizontal opening of the elevator shaft opening of a civil building is different from Embodiment 1 in that the locking device of this embodiment is an intelligent lock, which can be opened / closed by a controller.

Embodiment 3

[0043] The temporary rotating protective railing for the flat opening of the elevator shaft opening of civil construction houses is different from Embodiment 2 in that this embodiment is also provided with a pressure sensor or / and an infrared sensor, which is installed on the On the protective railing, the controller is also connected with an alarm, which is a horn.

[0044] On the basis of Embodiment 2, this embodiment adds an alarm function, which judges whether someone is approaching the elevator shaft opening through a pressure sensor or / and an infrared sensor. If the locking device is not closed, an alarm is issued to prompt this protection The railing is not closed, be careful not to enter.

Abstract

The invention discloses a flat-opening temporary rotating guardrail at an elevator shaft entrance of a civil building. The flat-opening temporary rotating guardrail comprises two guardrails, wherein one end of the two guardrails is respectively arranged at each of the two sides of the elevator shaft entrance through a rotating support base and is in rotatable connection with the elevator shaft entrance; the other ends of the two guardrails are interlocked with each other through a locking device; a fixing hole is formed on the rotating support base; the rotating support base is fixed on the outer side of the elevator shaft entrance in the manner of penetrating a bolt into the fixing hole. The flat-opening temporary rotating guardrail disclosed by the invention is designed as being made of section steel; the dedicated rotating support base can be reused; the construction measurement cost is lowered; the width of the two guardrails can be uniformly confirmed according to the width of each elevator shaft entrance and the size of the guardrails at the elevator shaft entrance can be reduced; the guardrail can be horizontally and outward rotated and opened in the process of temporary construction in the elevator shaft, so that the constructors can conveniently enter into the elevator shaft; the flat-opening temporary rotating guardrail can meet the neat, beautiful and safe standard of the guardrail of comprehensive floor; the civilized construction image can be promoted; higher social benefit can be acquired; the popularization and application values are higher.

Description

technical field [0001] The invention belongs to the field of building construction equipment, and is a temporary protective railing that can be quickly installed to protect the opening of an elevator shaft in a civil building during the construction of a civil building. railing. Background technique [0002] In the construction of civil housing projects, when the main frame of reinforced concrete on each floor is completed, there is no enclosure for the opening of the elevator shaft on the floor, and accidents such as falling of people and objects are prone to occur at the opening of the elevator shaft on the floor. Take temporary protection. Contents of the invention [0003] The purpose of the present invention is to provide a temporary rotating protective railing for the horizontal opening of the elevator shaft opening of a civil building, mainly to solve the problem that there is no enclosure for the elevator shaft opening of the existing floors, and accidents such as...
