Problems solved by technology

Both the government and the construction companies attach great importance to the safety protection of elevator shafts. At present, there are various types of safety protection for elevator shafts at construction sites, but it is difficult to achieve the expected safety protection goals.
The main reasons are as follows: firstly, due to the hysteresis of the elevator shaft safety protection railings, that is, during the construction process, the elevator shaft safety protection railings were not added in time with the increase of the floor; second, the elevator shaft safety protection railings were artificially removed during the construction process; It is difficult to fill the protective railing in time when the elevator shaft protective railing is missing
The above reasons lead to the occurrence of accidents caused by people falling from heights

Embodiment

[0018] Such as Figure 1-Figure 3 As shown, a protective railing that can be turned over is used. The protective vertical bar 6 is welded between the protective upper rail 4 and the protective lower rail 12. Both ends of the protective upper rail 4 are connected to be fixed on the concrete wall 1. The screw rod 5 in the hole 3 is fixed by the nut 10, the opening of the sleeve 8 is sleeved on the protective lower cross bar 12, the non-open end of the sleeve 8 is welded to the steel corner bracket 9, and the steel corner bracket 9 The end is connected with the door opening limit, and the foot guard 7 is arranged on the bottom of the protective railing.

[0019] The length of the screw rod 5 extending into the reserved hole 3 is 50mm.

[0020] The protective vertical bar 6 adopts Made of steel.

[0021] Described foot guard 7 is the wooden plate that is coated with red and white alternate colors of wide 200mm, and setting position is apart from floor 250mm place, and its lowe...

Abstract

The invention relates to the technical field of construction engineering, in particular to a revolving protective railing. The protective vertical rod is welded between the protective upper cross bar and the protective lower cross bar. Both ends of the protective upper cross bar are connected to the screw for fixing in the reserved hole of the concrete wall. The screw is fixed by the nut, and the opening of the casing Sleeved on the protective lower cross bar, the non-open end of the casing is welded with a steel bar corner bracket, the end of the steel bar corner bracket is connected with the edge of the door opening, and the foot guard is arranged at the lower part of the protective railing. Because the installation and disassembly process of the protective railing is very convenient and fast, the present invention can realize the purpose and requirement of safety protection for the edge hole, and truly achieve the effects of safety, reliability, economy, practicality, speed and labor saving.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a revolving protective railing. Background technique [0002] At present, in the construction industry, with the continuous development of urbanization, urban land is becoming less and less, which makes the construction continue to develop to a higher height. In high-rise buildings, vertical reinforced concrete cylinder structures such as elevator shafts and stairwells are generally used to resist more and more horizontal loads. In the process of high-rise building construction, elevator shaft protection is the focus of safety protection on the construction site, and it is also a high-incidence location for safety accidents falling from heights. Both the government and the construction companies attach great importance to the safety protection of elevator shafts. At this stage, there are various safety protections for elevator shafts at construction sites, but i...
