Further, wherein tie is installed as follows with method for dismounting: around the column template of installation, makes two tie mobile jibs intersect and presents four directions space mounting in column template periphery；Regulation tool-type tie mobile jib spacing, makes four directions space size adapt with the size of column template peripheral space, and both are against gapless；Tool-type tie main body is added the spacing saddle of tie, according to the spacing saddle number on four side space length of side size suitably homogenous layout ties；The fixing spacing saddle of tie, inserts the spacing saddle reserving hole on tie, fixing tie saddle position with connecting crab-bolt；Installing the spacing saddle of tie at tool-type tie main body infall, tool-type tie is fixed by recycling locking angle steel；Having only to intersect tie the crab-bolt of fixed position, locking angle steel and fixing saddle during dismounting removes, and whole tie just can be removed.
Further, the installation that beam skew back supports with method for dismounting is: the installation that beam skew back supports first has to the approximate size that the distance according to beam side determines that beam skew back supports, and greater depth is regulated by the position, hole between two sleeve pipes；Beam skew back is supported one end linked together by flat head bolt with bearing diagonal hold-down support, rotate bearing diagonal mobile jib, make the other end be connected with the reinforcement fin in inner corner trim mould, fix with flat head bolt；First rotate support bar during the dismounting that beam skew back supports and be at relaxed state, then remove the bolt of fixed position, two ends, then remove bearing diagonal.
Further, the installation of fast support with method for dismounting is: the point determined according to workmen's unwrapping wire places fast support, often place 2 rack rods to be just attached with cross bar, a fast rack rod is an elementary cell with 4, fast support at location, room four end points start the most longitudinally to be evenly arranged according to 1100mm, support installs rear mounting bracket top and connects seat；Can first remove and connect cross bar, the most successively striking vertical rod from the beginning of the one side in room when propping up the dismounting of support soon.
The positive Advantageous Effects of the present invention is following:
(1) standardization, fast, early tear open, high efficiency;
Tool-type steel framework Wood-plastic formwork system uses standardized components, standardized construction technology, standardized rack rod spacing and fast morning to tear support open, such that it is able to realize whole system Fast Installation and dismounting；By standardized construction technique, make to set up more simple and convenient, be greatly promoted artificial construction's efficiency, reduction of erection time, add investment return；
(2) safety coefficient is high, economical and practical;
By standardization vertical pole's span, standardized construction technique, safe and reliable connecting elements, improve the safety coefficient of workman in work progress；The utilization of standardized components reduces the expense during structure manufacture, has ensured the convenience producing component, thus has reduced component production prices, it is achieved that the target of low cost high repayment；
(3) low-carbon environment-friendly, economize on resources;
This system material uses steel and wood-plastic board, and steel back frame intensity high rigidity is big, and the number of turnover can reach more than 500 times, though steel back frame cannot repair after still can remanufacture rerolled steel entirely, comprehensive use cost is cheap, and almost without loss.Novel wood-plastic plate intensity is high, and abrasive resistance is strong, and form removal is easy, and use 20-30 time can be had enough to meet the need in plate face, and after plate face does not reaches level requirements, wood-plastic board can all reclaim, and as again producing the raw material of wood-plastic board, substantially achieves full recovery zero loss.Novel wood-plastic template plate face and the perfect adaptation of tool-type steel form back frame achieve " full recovery, zero loss " of template circulation material substantially.Compared with conventional template system, improve the turnover rate of template, decrease the wasting of resources of useless template, it is achieved that low-carbon environment-friendly economizes on resources.
