Description

A kind of superimposed sheet is installed and is supported with tool-type
Technical field
The invention discloses a kind of on-the-spot tool-type that usefulness is installed of reinforced concrete prefabricated superimposed sheet that is used for and support, support and form, belong to the civil engineering work technical field by vertical support bar, oblique drawbar, girt etc.
Background technology
Reinforced concrete sandwich plate commonly used is as the floor of structure in the precast reinforced concrete construction; This superimposed sheet is produced prefabricated superimposed sheet member in precast yard earlier; After the superimposed sheet member transports on-the-spot installation in position to; Assembling reinforcement is above it also built the overlapping layers concrete, finally accomplishes the construction of superimposed sheet.In this process, prefabricated superimposed sheet member will be born the deadweight of reinforced concrete sandwich layer and the corresponding working load on deadweight, top.Generally prefabricated superimposed sheet member does not have this supporting capacity, thereby needs to arrange support below the prefabricated superimposed sheet member with the minimizing structural span, thereby reaches satisfied purpose of carrying.Also some prefabricated superimposed sheet member just can reach load bearing requirements in order not establish to support; And take on prefabricated superimposed sheet member to increase the mode of rib; As increase steel bar girder, increase modes such as concrete rib; But owing to receive the restriction of thickness of slab condition, when plate is striden greatly, also uneconomical on the contrary by the mode that increases rib.And be stressed separately between traditional supporting way (similar template support) support and supported object, not forming cooperative structural bearing mode, thereby can not bring into play the supporting capacity that the superimposed sheet member has possessed fully, overall economic efficiency is not strong.The present invention is for giving full play to the existing structural-load-carrying capacity of prefabricated superimposed sheet member; Be provided with and the cooperative tool support of prefabricated superimposed sheet member; Make the two common string that forms prop up board-like structure; And bear upper load jointly, use can be repeatedly had enough to meet the need in the support of tool-type, thereby whole superimposed sheet installation economic benefit is improved.
Summary of the invention
The present invention can bear its top overlapping layers load of construction period for solving prefabricated superimposed sheet member safety economy; Providing a kind of superimposed sheet to install supports with tool-type; Be characterized in that this tool-type support forms string jointly with prefabricated superimposed sheet member and props up board-like structure; Improve the stress of superimposed sheet member, made structure reasonable more economically.
A kind of superimposed sheet of the present invention is installed and is supported with tool-type; Comprise: girt; At dismountable first oblique drawbar that is connected with of an end of girt with the first vertical support bar and be connected with the end of first oblique drawbar respectively with the first vertical support bar; At dismountable second oblique drawbar that is connected with of the other end of girt with the second vertical support bar and be connected with the end of second oblique drawbar respectively with the second vertical support bar; The first vertical support bar and the second vertical support bar adopt Adjustable bracing bar, and described Adjustable bracing bar comprises sleeve pipe and screw rod, and adjusting nut has been threaded on screw rod; One end of said sleeve pipe is set on the said screw rod and by adjusting nut and supports; On the other end of sleeve pipe, be provided with screwed hole, on the other end of first oblique drawbar and the first vertical support bar, be respectively equipped with screwed hole, on the other end of second oblique drawbar and the second vertical support bar, be respectively equipped with screwed hole.
The invention has the beneficial effects as follows:
1, the present invention, increases economic efficiency in application in engineering applicable to the bigger superimposed sheet of span.Support of the present invention and superimposed sheet member form string jointly and prop up board-like structure, have improved the internal force state of superimposed sheet member when bearing vertical load.Under vertical uniform load q; Vertical support bar of the present invention plays the effect that reduces superimposed sheet member span and vertical support power is provided; The bottom pull bar is drawn simultaneously, and the mode of pulling force with pressure is passed on the superimposed sheet member, and the compressive stress that this pressure produces in the superimposed sheet member will be offset the tensile stress in the superimposed sheet member; Thereby reduce or avoid the concrete cracking of superimposed sheet member, improved structural-load-carrying capacity.Thereby it has overcome with the too high restriction that influences the structure thickness of slab of anti-rib web height when span is big of anti-rib formula superimposed sheet on the one hand; Given full play to the existing structural-load-carrying capacity of prefabricated superimposed sheet member; Make steel that the superimposed sheet structure consumes, concrete material still less, structure is more economical.Of a large amount of uses of scaffold method for supporting have also been avoided directly under superimposed sheet, setting up on the other hand for material and manpower.So, forms string through the tool-type support jointly with prefabricated superimposed sheet member and prop up board-like structure, but the economical with materials use amount reduces manpower consumption, increases economic efficiency;
2, the string that this tool-type supports and prefabricated superimposed sheet member forms jointly props up board-like structure and can be good at solving the outer stable problem of braced structures face; The lower link of tensioning makes vertical support bar have good out-of-plane balance recovery capability; Vertical support bar stability is strong; Braced structures is succinct, has significantly reduced engineering quantity.
3, this tool-type supports and can pass through vertical Adjustable bracing bar in advance to girt and diagonal member pretension, and through diagonal member prefabricated superimposed sheet member is applied compressive pre-stress, reduces structure crack.
4, this tool-type supports and realizes that all detachably makeup is joined, and connector is less, and mounting or dismounting are convenient, and can have enough to meet the need use repeatedly, meet the requirement of modern construction technology development trend;
5, the pull bar and the built-in connection material of the support of this tool-type can be used reinforcing bar material commonly used, make with simple for use, and universality and economy are stronger.
