Description
Technical field
A kind of protective device is the utility model is related to, especially a kind of opening protective device, belongs to field of mechanical technique.
Background technology
At present, in reinforced concrete work work progress, in particular with the industrial premises of the structure, electric power plant
In room work progress, substantial amounts of hole can be usually reserved on floor.After the completion of constructing at this position, particularly rear civil construction rank
Section, because of the needs of safety construction, these holes are often required to do interim protection.It is in general, less for size
Hole, interim protection is done using glued board and flitch；And it is larger for dimension of opening, it is being used for glued board and flitch
After doing provisional protection, it is also necessary to steel pipe scaffolding fence is set up around it and is protected.But these safeguard procedures one are to wood
Side generates waste, second, more steel pipe, fastener are needed, third, needing frequent maintenance.The process of protection is more numerous above
It is trivial, and more human and material resources are taken, while do not meet the requirement of green construction.
Utility model content
The problem of the utility model is for above-mentioned protection inconvenience in hole existing in the prior art, proposes that a kind of hole is prevented
Protection unit, adapts to the protection requirements at different size holes.
The utility model solves technical problem, a kind of opening protective device, including center bearing bracket by the following technical programs,
The adjusted part connection supporting item in end of the center bearing bracket, the surface placement protective plate of the center bearing bracket and supporting item.It is logical
The distance of center bearing bracket and supporting item is overregulated, adapts to various dimensions of opening, and is installed simply, it is easy to maintain.
The utility model further realizes goal of the invention by the following technical programs, and the center bearing bracket is cross reinforcing bar,
One end of the cross reinforcing bar is formed with the screw thread being connected with regulating part, and the regulating part is sleeve, and one end of the sleeve connects
Cross reinforcing bar, other end connection supporting item, the supporting item is made of the bar dowel in the middle part of the connecting T-shaped angle steel of one end, described short
One end of reinforcing bar is formed with the screw thread with sleeve connection.Cross reinforcing bar is welded for the reinforcing bar of four or three unified specification models
Connect in succession, 25 grade III steel is preferably more than using diameter.
Before cross reinforcement welding, mantle fiber processing need to be carried out to one end of reinforcing bar, to be attached with sleeve.With it is T-shaped
One end of the bar dowel of Bolted angle connection need to carry out mantle fiber processing, to be attached with sleeve.
The cartridge exterior is symmetrically welded and connected rotating mechanism.The rotating mechanism is the round steel for being bent to c-type.The T
Protective port is formed between type angle steel, protective plate is disposed on the protective port.The protective plate is glued board, its sectional dimension is per side
Length be more than protective port size.
Compared with existing hole safeguard procedures technology, the utility model opening protective device is rational in infrastructure, easy to use, leads to
The rotation of sleeve is crossed, drives T-shaped angle steel to move forward and with hole edge lap and fitting closely, it is firmly combined with hole
Together.Then glued board is placed, the opposite side of T-shaped angle steel realizes the fixation to glued board, it is not rocked, so that
Realize the protection to hole.
The beneficial effects of the utility model are easy to operate, and security is good, and same model can be realized to a variety of different rulers
The protection at very little hole, has saved material, reduces cost, suitable for the protection at various floor holes, specifically realizes portion
The recycling of steel splitting muscle clout, T-shaped angle steel and old glued board；Only need to be by the either small steel of the common spanner in construction site
Dismounting can be achieved in muscle.Reduce artificial expenditure, reduce safety construction expense expenditure, played actively to cost-effective
Effect, while the present apparatus can be used in turn, and meet the requirement of green construction.
