Abstract
The invention discloses a concrete wallboard anti-crack steel-plastic grating web construction method. A positioning clamp is fixedly welded to a vertical steel bar of a wallboard and is used for hanging and fixing a steel-plastic geogrid, one end of the positioning clamp is bound to the steel-plastic geogrid, the other end of the positioning clamp is welded to the vertical steel bar of the wallboard and forms a composite interlocking system with a concrete wall, then conceal inspection is carried out, concrete pouring is carried out after conceal inspection is qualified, and maintenance work is carried out well after concrete pouring is finished. According to the method, construction is convenient to achieve, leaking and cracking phenomena can be effectively avoided, the concrete anti-crack requirement is met, concrete structural quality is well guaranteed, and obvious social benefits and economical benefits are achieved.
Description
Technical field
The present invention relates to a kind of concrete wall slab and mould cracking resistance grid job practices.
Background technology
Concrete material is current most widely used constructional materials, but concrete produces the shortcoming of embrittlement cracking because of contraction.Affected the use function of cracking resistance seepage resistance demand higher buildings, the crack of reinforced concrete structure and seepage, become the significant problem that perplexs reinforced concrete structure quality.
Summary of the invention
The object of the present invention is to provide a kind of concrete wall slab that causes seepage and crack phenomenon to occur of effectively avoiding to mould cracking resistance grid job practices.
Technical solution of the present invention is:
A kind of concrete wall slab is moulded cracking resistance grid job practices, it is characterized in that: comprise the following steps: after concrete panel reinforcing bar is checked and accepted, on wallboard vertical reinforcement, be welded and fixed locator card, for hanging and fixing steel plastic geogrid, one end colligation steel plastic geogrid of locator card, the other end and wallboard vertical reinforced-bar-welding, form compound interlocking system with concrete wall, steel plastic geogrid is arranged within the scope of the concrete cover that 50 ㎜ are thick, apart from body of wall vertical reinforcement 30 ㎜ and apart from concrete wall external surface 20 ㎜, steel plastic geogrid from external surface too close to concrete to the bond stress of steel plastic geogrid, can not guarantee, from external surface, do not reach effect of prestressed away from too, then carry out carrying out concrete construction after hidden acceptance(check), during concreting, adopt poker vibrator to carry out jolt ramming, vibration frequency and time are can make the composition of air effusion in mixture be as the criterion, the vibrator spacing of vibrating is 30～40 ㎝, insertion depth is 50 ㎝, after using secondary vibration technique 20～30min, shake again, the concrete protective bed thickness outside wallboard vertical reinforcement is 50 ㎜, after building, carry out maintenance work.
Described locator card is half-twist and " does " font, and steel plastic geogrid is fixed in head two parallel arms of " doing " font.
Easy construction of the present invention, effectively avoids causing seepage and crack phenomenon to occur, and has both reached the requirement of concrete anticracking, has well guaranteed again to have obvious Social benefit and economic benefit by concrete structure quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is steel plastic geogrid scheme of installation of the present invention.
The specific embodiment
A kind of concrete wall slab is moulded cracking resistance grid job practices, comprise the following steps: after concrete panel reinforcing bar is checked and accepted, on wallboard vertical reinforcement 1, be welded and fixed locator card 2, for hanging and fixing steel plastic geogrid 3, one end colligation steel plastic geogrid of locator card, the other end and wallboard vertical reinforced-bar-welding, form compound interlocking system with concrete wall, steel plastic geogrid is arranged within the scope of the concrete cover that 50 ㎜ are thick, apart from body of wall vertical reinforcement 30 ㎜ and apart from concrete wall external surface 20 ㎜, steel plastic geogrid from external surface too close to concrete to the bond stress of steel plastic geogrid, can not guarantee, from external surface, do not reach effect of prestressed away from too, then carry out carrying out concrete construction after hidden acceptance(check), during concreting, adopt poker vibrator to carry out jolt ramming, vibration frequency and time are can make the composition of air effusion in mixture be as the criterion, the vibrator spacing of vibrating is 30～40 ㎝, insertion depth is 50 ㎝, after using secondary vibration technique 20～30min, shake again, the concrete protective bed thickness outside wallboard vertical reinforcement is 50 ㎜, after building, carry out maintenance work.
Described locator card is half-twist and " does " font, and steel plastic geogrid is fixed in head two parallel arms of " doing " font.
