Description

Elevator shaft protection device

technical field

The utility model relates to a safety protection device in the construction process of high-rise buildings, in particular to an elevator shaft protection device.

Background technique

In the construction process of high-rise buildings, the elevator is generally installed after the exterior decoration and interior decoration are completed. Before the elevator is installed, the elevator door is in an open state, and the construction personnel have to carry out work indoors, such as plastering the floor and plastering the wall. There is a great safety risk, and when the bottom construction workers enter the elevator shaft, if there is a falling object in the elevator shaft, it will directly threaten the personal safety of the construction workers. In addition, the elevator door is open during the high-level operation. , without any protection, high-rise workers also have the risk of accidentally falling; therefore, it is very necessary to protect the elevator doors during the indoor construction of high-rise buildings; the existing protective measures are basically on the outside of the elevator doors Block a formwork, or drill holes on the wall to fix the steel pipe guardrail or formwork, but there are problems to varying degrees; if only one formwork is blocked without any fixing measures, the safety risk still exists, and if it is used on the wall The technical means of drilling and fixing guardrails or templates also needs to repair the fixing holes after the construction is completed, and the process is complicated, causing a certain waste of manpower and material resources.

Utility model content

The technical problem to be solved by the utility model is to provide an elevator shaft protection device, which can effectively reduce the safety risks of construction personnel and avoid waste of manpower and material resources in the construction process.

The technical concept of the utility model is realized in this way. The horizontal bars are arranged on the inner and outer sides of the elevator shaft, and the inner and outer horizontal bars are connected with diagonal stays to play a fixed role. In addition, two horizontal and two vertical steel pipes are set on one side of the room as guardrails, effectively Reduce the safety risk of construction personnel and avoid the waste of manpower and material resources due to drilling and fixing.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a protective device for an elevator shaft, including an inner cross bar located inside the elevator shaft, a vertical bar, an outer cross bar located outside the elevator shaft, and a and the diagonal stay rod of the outer cross bar; the fixed connection between the vertical rod and the outer cross bar; connect.

There is at least one inner cross bar, at least one outer cross bar, at least two vertical bars, and at least one diagonal tie rod.

There is one inner cross bar, two outer cross bars; two vertical bars; two diagonal tie rods.

The cross fasteners are used to connect the inner cross bar, the outer cross bar, the vertical bar and the diagonal stay bar.

The inner cross bar, the vertical bar, the outer cross bar and the oblique tie rods are all made of steel pipes.

The beneficial effect produced by adopting the above-mentioned technical scheme is that: horizontal bars are arranged on the inside and outside of the elevator shaft; A cross bar, and a diagonal tie rod fixedly connected to the outer cross bar and the inner cross bar, forming a safety protection railing fixed on the elevator door, which can effectively prevent the bottom construction personnel from entering the elevator shaft, and can also effectively protect the safety of the high-rise construction personnel. Of course, in In the specific use process, warning signs or protective plates can also be hung on the outer crossbar to enhance the protective effect; and there is no need to drill holes on the wall during the fixing process, which reduces the process of repairing the drilling holes after construction, and reduces manpower and material resources. waste. the

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is a schematic diagram of the utility model in use;

In the accompanying drawings: 1. Elevator door; 2. Inner cross bar; 3. Outer cross bar; 4. Vertical bar; 5. Diagonal tie rod; 6. Cross fastener.

Detailed ways

A kind of elevator shaft protective device as shown in Figure 1, comprises the inner cross bar 2 that is positioned at elevator shaft, vertical bar 4, is positioned at the outer cross bar 3 outside elevator shaft and is used for connecting inner cross bar 2 and outer cross bar 3 Diagonal tie rod 5; fixed connection between the vertical rod 4 and the outer cross bar 3; Fixed connection between.

There is at least one inner cross bar 2 , at least one outer cross bar 3 , at least two vertical bars 4 , and at least one diagonal tie rod 5 .

There is one inner cross bar 2 , two outer cross bars 3 ; two vertical bars 4 ; two diagonal stay bars 5 .

The cross fasteners 6 are used to connect the inner cross bar 2 , the outer cross bar 3 , the vertical bar 4 and the diagonal tie rod 5 .

The inner cross bar 2, the vertical bar 4, the outer cross bar 3 and the diagonal tie rod 5 are all made of steel pipes.

In the specific application process, first of all, the two outer horizontal bars and two vertical bars are fixed and connected with cross fasteners to form a grid structure. Connect, then erect the vertical bar, and stick the two outer bars to the wall, and finally extend the inner bar into the elevator shaft, its position is slightly higher than the top outer bar, and use the cross fastener to connect the diagonal bar The outer end is fixedly connected with the top outer crossbar. Both the outer crossbar and the inner crossbar can be made of ordinary shelf tubes, the length of which is slightly larger than the width of the elevator door. The overall guardrail can be fixed with the wall to play a protective role, and there is no need to drill fixing holes on the wall during use, and there is no need to repair the fixing holes after work, saving manpower and material resources, and can effectively ensure the safety risks of construction personnel .
