Abstract
The utility model relates to a one-time continuous poured circulating pipe network structure of super-mass concrete. The innovation point is that, the one-time continuous poured circulating pipe network structure of the super-mass concrete mainly comprises a circulating water steel pipe network and a preset support, wherein the preset support comprises a plurality of horizontal support steel pipes and vertical support steel pipes; the horizontal support steel pipes are connected with the plurality of vertical support steel pipes to constitute a stereo frame structure and then the stereo frame structure is placed between two brick wall interlayers of the super-mass concrete to be poured; the circulating water pipe network comprises a plurality of plane baffling circulating water pipes vertically arranged on the preset support and extended in S shape, and a circulating water inlet manifold and a circulating water outlet manifold respectively communicated with the water inlet and the water outlet of each plane baffling circulating water pipe. Low-temperature water is sent to each area in the concrete by the circulating water pipe network, and drains outwards for cyclic exchange after the heat of the water is absorbed, so that the hydration heat high-temperature area in the concrete is difficult to concentrate, influence to restraining around the concrete is reduced, temperature-control construction bars, cushion sliding layers and external restraining and mitigating measures of the structure are not needed to arrange, and thus the construction progress is sped up and the construction cost is reduced.
Description
Technical field
The utility model relates to a kind of concrete cooling equipment, ultra-large volume concrete one-time continuous cast circulation pipe network structure.
Background technology
At present China's engineering construction development rapidly, high-rise, super highrise building is increasing, and the application of prevention of mass concrete is also more and more extensive.In Mass Concrete Construction process, because hydrated cementitious heat effect produces very large heat, concrete surface heat loss is very fast, and internal heat is difficult for distributing, thereby inside produces the larger temperature difference with surface.When the temperature difference surpasses certain threshold, can produce thermal stresses, when this temperature tensile stress is greater than the tensile strength of concrete, concrete structure just can produce crack, thereby affects the durability of engineering.
The 5.1.4 bar of < < mass concrete construction standard > > (GB50496-2009) has been introduced the common three kinds of construction methods of " indwelling deformation joint ", " in conjunction with ater-casting ", " jumping storehouse method construction " of Present Domestic for " super long mass concrete "; In addition, for Present Domestic " super mass concrete ", adopt whole stratified continuous pouring or passing formula continuous placing and the measure of multiple heat insulating material covering and heat insulating more, distributing bar is set, sliding layer on bed course is set, arranges and reduce external constraint measure etc., this standard also has certain description to this.
But for " ultra-large volume concrete ": above-mentioned construction method, although solved the problem that produces crack, also exists the shortcoming time-consuming, expense is expected, taken a lot of work etc.Therefore research and develop a kind of more reasonably ultra-large volume concrete one-time continuous pouring procedure and corollary equipment thereof imperative.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of ultra-large volume concrete one-time continuous rational in infrastructure, good cooling results and pours into a mould circulation pipe network structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of ultra-large volume concrete one-time continuous cast circulation pipe network structure, its innovative point is: mainly comprise recirculated water steelpipe net, preset support, preset support comprises some horizontal support steel pipes and vertical support steel pipe, described horizontal support steel pipe forms " well " font plane structure by horizontal cross supporting steel pipe and horizontal longitudinal bracing steel pipe, and connects and composes in the two brick wall interlayer that a space frame structure is placed on ultra-large volume concrete to be cast by some vertical support steel pipes; Recirculated water pipe network comprises that several are vertically set on the plane baffling circulating water pipeline that the serpentine in preset support extends, and the recirculated water water inlet manifold and the recirculated water outfall sewer that are communicated with respectively each plane baffling circulating water pipeline water inlet and delivery port; Described plane baffling circulating water pipeline is connected and composed by elbow successively by some horizontal cyclic water steel pipes, vertical circulation water steel pipe, and horizontal cyclic water steel pipe drops on the horizontal support steel pipe of preset supporting.
Further, described horizontal cyclic water steel pipe, vertical circulation water steel pipe, elbow specification are ￠ 48mm.
Further, described horizontal cyclic water steel pipe, vertical circulation water steel pipe and elbow are threaded connection.
Further, in described plane baffling circulating water pipeline, the vertical interval of adjacent upper and lower horizontal cyclic water steel pipe is 800-820mm; And the level interval of adjacent plane baffling circulating water pipeline is 900-1100mm.
The utility model has the advantage of: utilize recirculated water pipe network that water at low temperature is sent into each region, concrete center, after absorbing heat, outer row's circulation exchanges, make concrete internal water heat-transmission high-temperature region be difficult to concentrate, reduced the concrete impact of constraint around, can not establish temperature control structure muscle, bed course sliding layer and structural outer constraint and slow down measure, accelerating construction progress, reduces construction cost; And there is extremely strong operation initiative, can improve the conventional way of passive insulation, reduce difficulty of construction, reduce concrete internal high temperature stress deformation occurrence risk.
Recirculated water pipe network adopts short scaffolding steel pipe to be made, for waste recovery utilization, and can with sole plate, cushion cap reinforcing bar operation synchronous construction, economic and practical is strong, constructing operation is convenient, construction technology is simple, easily grasp, production efficiency is high, safe and reliable, construction cost is low, and " ultra-large volume concrete " construction is had to good application value.
