Abstract

The invention discloses a secondary casting molding construction method of a cast-in-situ concrete stand structure. After oblique beams under a frame column and a stand plate are cast, the stand plate structure is constructed in the second time. The secondary casting molding construction method is subjected to the casting for two times through the adjustment of construction joints, so that the construction difficulty is reduced, the construction of a main component, namely a stand beam is ensured, and a condition is created for the main body construction of other main components in the periphery of the stand beam. During the stand plate construction, the construction for the peripheral main body structures can be carried out continuously at the same time, and a lot of time is saved for the subsequent construction.

Description

Cast-in-situ concrete stand structure second pouring molding construction method
Technical field
The present invention relates to technical field of building construction, be specifically related to a kind of cast-in-situ concrete stand structure second pouring molding construction method.
Background technology
Along with steadily improving of people's living standard, the consciousness that the whole people pursue physical culture, culture life progressively strengthens, and the large-scale utilities buildings such as stadiums in all parts of the country, drama institute are more and more.Grandstand is as the indispensable ingredient of the type building.Its job practices often directly has influence on integral construction speed and the construction quality of this project.
There is no at present the stand structure secondary and build moulding process, but in conjunction with sports center, Qingdao City natatorium and diving pool engineering, studied the construction technology that the grandstand beam slab is divided into two-step pouring, engineering time proves, this technique does not affect the above structure construction of grandstand, greatly accelerating construction progress.
Summary of the invention
Technical problem to be solved by this invention is: a kind of cast-in-situ concrete stand structure second pouring molding construction method is provided, solves Stand Inclined Beams and see when platen is built simultaneously, the cant beam bottom will produce the problem than high thrust.
The technical scheme of technical solution problem of the present invention comprises the steps:
A, Stand Beams formwork erection and support scaffolding;
At the bottom of b, the Stand Beams and a side template install;
C, Stand Beams reinforcing bar and back plate muscle are reserved;
D, Stand Beams opposite side formwork reinforcement also arrange gauze wire cloth;
E, Stand Beams concreting;
F, the cleaning of interface, constuction joint place;
G, viewing platform form board install;
Interface cleaning and the grandstand reinforcing bar binding of h, Stand Beams;
I, grandstand concreting.
Stand Beams concreting among the described step e, use delivery pump directly with concrete conveyance to building a little, reduce the variation of water/binder ratio in the concrete transportation, placement layer by layer in order from low to high, one-time-reach-place, guarantee the continuity of concreting, adjacent sections is built be not more than blanking time concrete initial set time.
Viewing platform form board in the described step g installs, and the measures such as employing sticking two-faced adhesive tape guarantee that the constuction joint seam is tight.
Grandstand concreting in the described step I, before building the constuction joint place clean first wetting, then build 10~15mm thick with concrete with the proportioning mortar, construct again, select the little concrete of the slump to build.
The invention has the beneficial effects as follows: the construction of grandstand beam slab of the present invention, reduced difficulty of construction, guaranteed the construction of main member Stand Beams, for other main member main body construction of Stand Beams periphery creates conditions, when seeing the platen construction, can proceed the construction of perimeter body structure, for the plenty of time has been saved in follow-up construction.Since the greatly shortening of duration, a large amount of saving that brought turnover material tool, overhead cost etc.Prove that by practical engineering application the present invention has preferably techno-economic effect and higher application value.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further disclosure.
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of cast-in-situ concrete stand structure second pouring molding construction method comprises the steps: a, Stand Beams formwork erection and support scaffolding 1; At the bottom of b, the Stand Beams and a side template install; C, Stand Beams reinforcing bar and back plate muscle are reserved; D, Stand Beams opposite side formwork reinforcement also arrange gauze wire cloth; E, Stand Beams concreting, use delivery pump directly with concrete conveyance to building a little, reduce the variation of water/binder ratio in the concrete transportation, placement layer by layer in order from low to high, one-time-reach-place, guarantee the continuity of concreting, adjacent sections is built be not more than blanking time concrete initial set time; F, the cleaning of interface, constuction joint place; G, viewing platform form board install, and the measures such as employing sticking two-faced adhesive tape guarantee that the constuction joint seam is tight; Interface cleaning and the grandstand reinforcing bar binding of h, Stand Beams; I, grandstand concreting, before building the constuction joint place must clean first wetting, then build 10~15mm thick with concrete with the proportioning mortar, construct again, select the little concrete of the slump to build.
The above is not to be limitation of the present invention, and every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
