Description

The frontier defense protection structure is faced in sustainable turnover

Technical field

The utility model is about a kind of building safety safeguard structure, refers to that especially a kind of sustainable turnover faces the frontier defense protection structure.

Background technology

In the high-building construction, the safety of facing the limit operating personnel is the most important thing of safety management, current domestic construction industry is protected and is normally adopted steel pipe (tubing of φ 48 * 3.5mm) as railing and baluster for the frontier defense of facing in the highrise building, in the fastener mode that it is fixing each other, its shortcoming has:

1) when material adopts lease, lease after date and can not continue to use, do not form the recycling of material as much as to say; If long-term the employing leased, will produce huge lease expenses;

2) when material adopts purchase, use problem though solved the turnover of material, the disposable input of the buying expenses of steel pipe, fastener is very big.

And reinforcing bar or other steel (as angle steel etc.) are made guard rail and baluster, during in the fixing mode of electric welding, have following shortcoming equally:

1) as the reinforcing bar or the steel of railing, all need carry out scale processing according to the width that faces the limit, so the limit of facing of different in width can not be general, this railing way versatility is poor, and turnover property is poor;

2) adopt electric welding to fix between reinforcing bar or the steel, because that the frontier defense amount of protecting is faced at the scene is very big, need a large amount of electric welding personnel constructions, artificial amount is big, the expense height;

3) reinforcing bar or the disposable input ratio of steel buying expenses are bigger.
