Description
Technical field
This utility model relates to the concreting technical field of building trade, is applicable to, particularly to a kind of, routine or the special-shaped stiffness concrete column concrete pouring structure that all kinds of steel content is big, internal structure is complicated.
Background technology
At present, large scale business engineering, public buildings are presented in the life periphery people as gush, it is while pursuing the big scale of construction, large space, constantly weed out the old and bring forth the new, do things creatively, strengthening the resolution of building from structure design and construction style, fall over each other to contend the center reference point image in city, the stiffness structure developed therewith has become the new lover of this type of architectural design especially.In order to improve the bearing capacity of this type of vertical direction spatial supporting member, and control self cross section of consequent component greatly, from heavy technological deficiency, heavy in section steel tube concrete frame puncheon and steel reinforced concrete short columns with regard to this formation.
But when concrete engineering construction, for steel core concrete column, owing to its segmental hoisting assembly welding height is higher, and in it, it has been abound with shear stud and stiffener, conventional chute or tumbling barrel can be only put at capital grouting mouth and carry out high-order cloth, in casting process, concrete easily isolates, and column body concrete pouring compaction rate and quality cannot ensure, have a strong impact on the design bearing capacity of steel core concrete column；For rigid steel reinforced concrete column, when after cylinder template matched moulds, reinforcing bar, peg and reinforcing bar in cylinder etc. are arranged intensive, concrete is under conventional capital casting craft, concrete is by deadweight dropping process, sandstone cement is easily broken up hanging fascia by its interior reinforcing bar, reinforcing bar, there is serious isolation, even cause column body concrete hollow, honeycomb, cut the major quality defects such as stifled, especially at the pouring construction of the special-shaped stiffness concrete columns such as all kinds of Y types, inverted cone-shaped, greatly have impact on concrete Survival Rate.
Therefore, on the premise of guaranteeing that tall and big special-shaped cylinder one-time-concreting survives, how to reduce concreting process isolation, improve concrete compaction pouring quality, the big technical barrier that the stiffened column having become this type of reinforcing bar to gather is constructed.
Utility model content
This utility model causes concreting isolation because reinforcing bar in it, reinforcing bar gather to overcome existing tall and big stiffened column and steel pipe column, is difficult to water quality risk and the drawbacks such as closely knit, improve column body concrete Survival Rate, on the basis of existing cylinder casting craft, carry out technological improvement, form the biggest a kind of scale of construction stiffened column body and slip ball conduit string pipe concrete pouring structure.
The taked technical scheme of this utility model is: on the ground big scale of construction stiffened column body slips ball conduit string pipe concrete pouring structure, it is characterized in that: pour flexible catheter and concatenate by conduit threading snare hoop is elongated with wire, the bottom of wire is fixed with the concrete prefabricated through hole slipping ball and is connected, the top connecting port pouring flexible catheter engages with concrete hopper or pump line discharging opening, string pipe is embedded at the stiffener pouring hole at stiffened column body flex point position in advance, and the osculum diameter of string pipe is more than the concrete prefabricated diameter slipping ball.
Further, described conduit threading snare hoop includes threading circle, conduit cuff, and threading circle is fixedly linked with conduit cuff, and in threading circle, fixing connection wire, fixes connection in conduit cuff and pour flexible catheter.
Further, 1.1 1.25 times of a diameter of wire diameter of described threading circle, a diameter of pour flexible catheter diameter 1.05 1.15 times of conduit cuff.
Further, termination, the junction sealing off and covering anchorage of the bottom of described wire and the concrete prefabricated through hole slipping ball.
Further, the described concrete prefabricated material slipping ball is identical with stiffened column body concrete, the concrete prefabricated a diameter of 60-80mm slipping ball.
Further, described in pour flexible catheter through standard connecting port segment processing, every section engages in inverted cone, and every segment length is 2.4-3.0m, pours the diameter of flexible catheter identical with the concrete prefabricated diameter slipping ball.
Further, described string pipe is the unidirectional horn mouth rigid casing of a length of 150-300mm, big mouth at upper, osculum at lower placement, a diameter of pour flexible catheter diameter 2.0-2.5 times of big mouth, and no more than stiffened column headroom inner chamber, a diameter of pour flexible catheter diameter 1.2-1.5 times of osculum.
Further, the specification of described wire is 1.0-4.0mm, be positioned at the wire at stiffness cylinder upper port be fixedly connected at stiffness cylinder upper port arrange steel wire fix on bar.
Further, the arrangement pitch of described conduit threading snare hoop is 1.2-2.0m.
This utility model has the advantages that
1, concrete is used to slip ball, auxiliary flex point string pipe design, can easily conduit be walked the bottom introducing special-shaped cylinder, the ball that simultaneously slips can forever pour disappearance as concrete；
2, owing to using tremie placing construction, concreting transmits independent in path, is not obstructed by the space of reinforcing bar, reinforcing bar etc. in cylinder and isolates, it is ensured that the mixing quality of concrete to casting position and performance；
3, column body concrete pours and can select the modes such as tower crane hopper blanking, or machinery pumping flexibly according to field condition, without taking the tower crane hopper blanking that tradition is single completely, improve the efficiency that column body concrete pours；
4, due in cylinder casting process catheter tip discharging opening be buried in below concreting face all the time, column body the most progressively can be filled close by deadweight and fill real by concrete, avoid inclusion of air to be detained the mass defect produced, can realize seamless pouring standard；
5, it is not only suitable for the concrete pouring construction of big scale of construction chapped pipe cylinder and stiff steel reinforced column, is simultaneously applicable to use big punching block pouring construction abnormity frame post to construct；Both can guarantee that the one-time-concreting of tall and big shell of column concrete, can guarantee that again that concrete poured in concealed space closely knit.
