Description

To pulling-on piece subassembly, construction support system and cast-in-place self preservation temperature enclosure wall

Technical Field

The utility model relates to a system and cast-in-place self preservation temperature enclosure wall are strutted to lacing film subassembly, construction belongs to the building technology field.

Background

In the construction process of commercial buildings, residential buildings and industrial buildings, the requirements on the heat insulation performance and the construction quality of the external wall are higher and higher. The existing external wall external insulation cast-in-place concrete composite insulation system is mainly characterized in that a steel wire mesh frame insulation board is arranged between an external template and an internal template, the external template, the insulation board and the internal template are connected through connecting pieces, and then concrete is poured in a cavity formed among the insulation board, the internal template and the external template. After the concrete is solidified, the heat-insulating plate and the concrete are formed into a whole, and the heat-insulating plate has the advantages of firm fixation, long service life, short construction period and the like.

The common internal and external building templates include wood templates, steel templates, plywood templates, plastic templates, glass fiber reinforced plastic templates, aluminum alloy templates and the like. The aluminum alloy template has the advantages of light weight, high rigidity, good durability, high production standard degree, relatively high construction speed, high times of template turnover and low material consumption, and is a novel template which can effectively improve the construction efficiency, ensure the construction quality and obviously reduce the construction cost. The aluminum alloy template is connected with the joint position of the aluminum alloy template in a split manner by using the disposable split piece as a connecting piece, the template is dismantled after concrete is solidified, the exposed part of the split piece exposed out of the wall body is broken, and the rest part of the split piece is left in the wall body, so that holes are prevented from being left on the wall, later-stage filling is not needed, and the aluminum alloy template is more convenient and faster for a split bolt system.

When the existing external wall external thermal insulation cast-in-place concrete composite thermal insulation system is constructed, the inner side of a steel wire mesh frame thermal insulation board is leaned against a concrete steel bar mesh frame, the outer side of the steel wire mesh frame thermal insulation board is positioned with an external template through a cushion block, and the internal template and the external template are fixed through a connecting piece. The pair of pulling-on pieces are common connecting pieces used for installing and fixing the steel wire mesh frame heat insulation plate, the inner formwork and the outer formwork. However, current when practical application to the pulling-on piece, can not guarantee yet to obtain effective restraint between wire net frame heated board and interior template and the exterior sheathing, pouring impact can make the heated board take place to the interior template skew when the heated board when pouring concrete, leads to the thickness of concrete main part not up to standard to arouse structural stress potential safety hazard, perhaps makes in the crowded embedding heat preservation of cushion, and the heated board takes place to the exterior template skew, leads to the thickness of outside protective layer not up to standard to arouse fire prevention potential safety hazard.

Secondly, traditional wire net frame heated board receives its structural characteristic to influence, and the cost of transportation is high and receive handling influence easily to produce deformation or matter and become and arouse the quality problem in the transportation, causes the equipment degree of difficulty greatly, the equipment precision is poor, the piece interval is too big scheduling problem because of the characteristic of its wholeness processing easily when the equipment to difficult cutting tailors etc. and causes the secondary operation difficulty.

Thirdly, traditional external wall external insulation cast-in-place concrete composite insulation system, the oblique steel wire that inserts on the wire net rack heated board leads to pouring the cavity narrowly between heated board and the exterior sheathing, and the closely knit difficulty of concrete vibration produces the cavity easily, and especially narrow department need adopt self-compaction concrete placement, and material cost is higher relatively, leads to current external wall external insulation cast-in-place concrete composite insulation system price/performance ratio not high.
