Description

Simple and easy integration entrance to a cave protector

Technical Field

The utility model belongs to the technical field of the entrance to a cave protection among the building construction process specifically is building structure work progress to great simple and easy integration safety device who faces limit entrance to a cave.

Background

Face limit entrance to a cave in-process in the building construction includes: elevator room, ventilating shaft, tube well and basement sump pit etc. these portals all are the area that falls of going out of height and very easily trample empty and drop. Aiming at the situation, the conventional method is to set up a protective railing near the opening to block constructors outside the opening, or directly cover the opening with a steel pipe and a template, or reserve a steel bar net before pouring concrete.

However, such methods also have a number of disadvantages:

the method for protecting the barrier still has a large risk that garbage and sundries at the opening fall to hurt people, and great inconvenience is brought to processes such as plastering, building and the like near the opening; the method for directly covering the steel pipe and the template is easy to loosen, move and deform to generate loopholes, and the method is the most original method and the method which is most easy to cause accidents on a construction site; the method for pre-embedding the reinforcing steel mesh in advance at the opening has a good protection effect, but is high in cost, troublesome in later-stage reinforcing steel bar cutting and has potential safety hazards.

The high-altitude falling is the first injury of four injuries in the building industry, the occurrence frequency is the largest, and the danger is the largest, so that the working environment of construction workers is enhanced, and the improvement of the traditional safety protection device for reserving the hole is the most important.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple and easy integration entrance to a cave protector can avoid improving operation personnel's security owing to face the probability that the high altitude accident of falling that the limit entrance to a cave leads to takes place, and this protector reuse simultaneously, fast ann tears open, saves labour and saves labour in the time of saving and economizes the material, does not influence entrance to a cave edge workman's normal construction operation moreover.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a simple and easy integrated entrance to a cave protector, include evenly fixed in the entrance to a cave pendant of both sides of entrance to a cave, steel pipe and flitch placed in the upper end of the said steel pipe on the pendant of said entrance to a cave, the said entrance to a cave pendant includes small-scale steel pipe, L-shaped steel plate and channel-section steel, the long edge welding of the said L-shaped steel plate has channel-section steel and offers the bolt hole, its minor face longitudinal welding has small-scale steel pipes in the middle position, both ends of the said steel pipe are mounted in channel-section steel; the waist guard device is characterized by further comprising a vertical rod fixed at the upper end of the small steel pipe on one side and a waist guard rod transversely fixed on the vertical rod.

Preferably, the waist blocking rods comprise two waist blocking rods which are uniformly fixed on the vertical rods.

By last, the utility model discloses a simple and easy integration entrance to a cave protector possesses following beneficial effect at least:

firstly, the assembly and disassembly are quick and traceless. The utility model discloses the component that uses in the device is the equipment component, does not need traditional processes such as drilling, pre-buried, installation and dismantlement that can be very fast have market spreading value. The mounting and dismounting process avoids the damage to the building structure to the maximum extent, thereby protecting the quality of the building structure and avoiding the post-processing and repairing work.

Secondly, the protection ability is strong, and the promptness is strong. Traditional railing protection or bar planting net piece protection still remain the entrance to a cave in fact, have rubbish, debris fall to hinder people's risk to the entrance to a cave region can't be current. The utility model discloses but cast-in-place floor concrete stress component is analogized to the device, through the template atress, passes to the secondary beam, arrives the girder again, finally passes to the floor through the entrance to a cave pendant, has fabulous bearing capacity, has trafficability characteristic, has made things convenient for the constructor operation of floor. The template surface is parallel and level with the opening and is paved on the opening, thereby not only being beautiful, but also achieving the purpose of opening protection without dead angles. And because the device has the characteristic of quick assembly, the device can construct a hole protective net at the first time, and the edge safety of a construction site is ensured.

Third, this protector suitability is strong, not only be suitable for with the protection of general entrance to a cave such as elevartor shaft, can also set up protector to some structural edge's entrance to a cave and ensure safety, can satisfy different grade type entrance to a cave safety protection's setting, further saved manual work and material.

The fourth, carry the effect and fall the expense, the utility model discloses the device ann tears simply open, and materials such as entrance to a cave pendant, steel pipe, template that use are the building site and are visible everywhere, only need simply assemble the purpose that just can satisfy the entrance to a cave protection, and the protection efficiency is high. The component can repeatedly have enough to meet the need the use, and steel components such as entrance to a cave pendant, steel pipe can use for almost unlimited time under the condition of doing well rust-resistant work, and consumptive materials such as flitch, template then can adopt construction waste material, realize waste utilization, so, the device has saved manual work and material loss, has reduced the input cost of entrance to a cave protection.
