One faces frontier defense protection unit and vertical rod thereof
Technical field
This utility model belongs to construction auxiliary equipment field, is specifically related to one and faces frontier defense protection unit and vertical rod thereof.
Background technology
In building construction process, face limit, stairs port limit, roofing periphery, light shaft periphery at deep foundation, turn and expect that platform periphery, balcony limit, walkway dual-side, discharging platform dual-side must be unified to install safety protection facility, safety and the project progress of engineering are played vital effect by these protective equipments, are the key factors controlling safety compliance.
Current building faces frontier defense and protects the following two mode that generally adopts: one is carry out Assembling with steel pipe and all kinds of fastener to set up, and this method technique is coarse, poor stability, it is difficult to meet the security protection requirement day by day strengthened;The steel pipe, the fastener amount that are used are big, and cost is high, and must start until top layer carries out vertical rod from bottom, take ladder lane, hinder and enter stair line laying work;Highlight outside steel pipe when setting up, hinder current, and the personnel that easily cause collide injury;Two is use tool-type guard rail, generally adopt standard package such as main vertical rod, upper and lower cross bar, the solid steel plate of main vertical rod, Corner Link, fixing bolt, screw etc. are assembled into temporary protection railing, former mode of comparing is attractive in appearance many, eliminate outside steel pipe prominent, hinder current drawback.But, above two protection method must utilize built-in fitting such as expansion bolt etc. to be fixed with the fixing of structural plane, or creeps into row perforate in the electricity consumption of fabric structure face, installs expansion bolt and is fixed.The former arranges built-in fitting in prefabricated components will increase extra work amount and cost, building perforate is destroyed the structure of original building by the latter to a certain extent, and the two faces after frontier defense protects in dismounting, need again structural plane is repaired, not only waste time and energy, the structural plane that also can affect attractive in appearance.Thus, current frontier defense maintaining method significant discomfort of facing answers the development of building industrialization, it is necessary to designs and new-type faces limit protective equipment.
Utility model content
The purpose of this utility model is to provide a kind of new-type clamp-type and faces frontier defense protection unit and vertical rod thereof, does not need to install built-in fitting, will not destroy the structure of precast concrete simultaneously in installing and using process, installs simple, saves cost, reusable.
Above-mentioned purpose is to be achieved through the following technical solutions: a kind of vertical rod facing frontier defense protection unit, including vertical rod body, described vertical rod body is provided with clamping device, and described clamping device includes at least two holder, described holder at least one be flexibly connected with vertical rod body.So arrange, this utility model is replaced traditional the fixing of frontier defense protection unit vertical rod structural plane that face and built-in fitting such as expansion bolt etc. must be utilized to be fixed, or creep into row perforate in the electricity consumption of fabric structure face, the mode that expansion bolt is fixed is installed, do not need again in prefabricated components and built-in fitting is set, also without the structure that building floor perforate is destroyed original building, install simple, save cost.
