Description

Improved tunnel opening protective fence for building construction Technical Field The utility model relates to a protection structure, in particular to an improved hole protection fence for building construction, which is mainly used for shielding and protecting some temporary unsealed reserved construction holes in the building construction and preventing the risk of careless falling of extraneous personnel or constructors, and belongs to the technical field of building construction safety protection. Background In general, in the process of building engineering construction, temporary unblocked holes, such as holes after pile foundation pore forming, reserved holes on floors, structural holes, and the like, often give a safety hazard to a construction site before the next construction is performed. According to the 4.2 regulations in the 'construction high-place operation safety technical Specification' JGJ, when the short side size of the non-vertical opening is more than or equal to 50cm, a protective railing or a horizontal protective measure is adopted, and when the short side size of the non-vertical opening is more than 150cm, a protective railing and a horizontal protective safety net are adopted. Therefore, the protection of the hole of the construction site is an essential link of engineering safety construction, and how to quickly install and detach the protection railing of the hole directly influences the progress and safety of engineering construction. At present, traditional entrance to a cave protection railing adopts the steel pipe fastener to set up and adopts the mode of plank, wire netting, although simple structure, but the effect is more single, because the material of steel pipe and operation workman's technical reason such as, the protection railing that the steel pipe fastener set up installs and removes speed and railing height, length, steel pipe interval etc. can not accomplish unification, and waste time and energy when adopting foretell steel pipe fastener to set up, occupation space is big, the protection effect is also relatively poor, to the construction of some town roads, a lot of protection is with the road warning sign that can only play single face protection or directly adopt the roadblock to carry out single face protection, and these protection components still can often be dismantled by other people and use its department of moving, cause the potential safety hazard, influence the safe civilized construction of whole engineering. Although the existing structure is designed with a device specially used for protecting a reserved hole in building construction, the protection device of the existing structure has the problems of complex structure, time and labor waste in the installation process, difficult transportation, large occupied area and inconvenient transportation, so that the protection effect is directly affected, potential difficulties and dangers are caused in the protection work, and potential safety hazards are brought; On the other hand, a plurality of protection devices are not provided with related safety protection warning signs or corresponding safety warning banners, the public and third parties cannot recognize the danger existing around the protection devices quickly, meanwhile, passers-by persons or vehicles cannot recognize the potential safety hazards quickly, so that constructors or other persons can not contact or fall into the protection devices carelessly, the accident occurrence risk is increased, even consequences are not supposed to be serious, the existing structure can be detached, but the existing structure is inconvenient to detach, assembly needs to be carried out one by one, and when some pavement protection is carried out, construction is carried out at the position where constructors are needed to frequently enter and exit, time and labor are wasted when the fence stability is reduced if the constructors are detached frequently, and the construction efficiency is affected. In some construction sites, some waste battens are often used for plugging reserved holes, so that safety accidents are avoided, and even special persons are used for taking turns to sit and care. On the other hand, the device is inconvenient to carry and move, and cannot be flexibly moved to a designated construction position according to the requirement of actual site construction, so that the device is quite inconvenient in all cases. Therefore, development of an opening protection fence with high practicability and high working reliability, which is convenient for assembly and disassembly, is a key point for solving the technical problems. Disclosure of Invention Aiming at the defects and shortcomings in the background art, the utility model improves and innovates the defects and aims at providing an opening protection structure with good protection effect and uniform style, according to the utility model, the fence with uniform patterns is processed by us
