Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described, but do not limit the present invention.
Order with jump storehouse, interval and strengthen the overlong jointless structural construction method that combines, construction method comprises order and jumps construction organization technology and interval that storehouse combines and strengthen the construction organization technology that combines;
Order combines with jumping storehouse, interval combines with reinforcement and refers in concrete pouring construction the adjacent construction section meeting the shortest intermittent time, the construction method that employing order combines with jumping storehouse, to not meeting the shortest intermittent time, the adjacent construction section of jumping storehouse method can not being used again, adopt the construction method of intermittent reinforcing band;
Overlong jointless structural construction refers to that exceeding specification to length must arrange the building that ater-casting specify, does not arrange the method for the disposable sequence construction in any control temperature contraction ater-casting;
The shortest intermittent time be by experiment and the concrete temperature that draws of theory analysis shrink, in controlled range, the shortest of adjacent concrete construction section builds interval time.
1, the construction organization technology sequentially combined with jumping storehouse
For ensureing the jointless construction of Overlong Concrete Structure, under different construction requirement, keeping jointless construction, mainly taking the mobilization that order combines with jumping storehouse.First choose a typical condition of construction to be described, the face of making even is 160 meters of * 60 meters of operation sides, is divided into Liang Ge great district: I and II; 8 construction sections, are numbered A/B/C/D/E/F/G/H.
(1) as shown in Figure 1, when order cross construction can meet the requirement of the shortest intermittent time, then subregional order cross construction is organized; Can be changed the intermittent time by the construction organization of adjustment critical process (reinforcing bar), to meet the requirement of the shortest intermittent time or duration.In I, II Liang Ge great district, carry out cross construction respectively, sequence of construction as shown in the figure, i.e. construction section A → B → C → D and construction section E → F → G → H.The duration is tight and when can meeting the requirement of the shortest intermittent time, can pass through the node extending forward critical process, make it form certain parallel construction, to accelerate speed of application, that is: parallel combination with flowing water is constructed.Critical process reinforcing bar binding carries out certain parallel construction, thus accelerates speed of application.
(2) as shown in Figure 2, the duration tight and can not meet the shortest intermittent time require time, can select the method for jumping storehouse construction, its construction organization should be parallel construction or flowing water are constructed with parallel combination.Namely construction section A, C, E, G section of first constructing is constructed construction section B, D, F, H section again.Be concrete in mass at main building, its shortest intermittent time is long and sequence construction can not meet the demands time, also can adopt and jump storehouse with order in conjunction with construction.
(3) body of wall 1 and basement floor slab construction tissue.One, consistent with base plate subregion; Its two, body of wall 1 can not meet the intermittent time require time, subregion can be increased to reduce the pinch confinement of base plate to body of wall 1.As shown in Figure 3, body of wall 1 has carried out corresponding subregion by base plate.
2, interval and the construction organization technology strengthening combining
As shown in Figure 4, when engineering adjacent area need be built for meeting construction period in 1-3 days, can not the shortest intermittent time be met, when can not carry out again the method construction of jumping storehouse, the construction method of selectively-expandable reinforcing band 2.Here select a typical project case, the method is described.
Operation side is A/B/C/D/E/F six construction sections, and sequence construction is construction section A → B → C and construction section D → E → F; As required, construction section is built simultaneously, can arrange expansion reinforcing band 2, reach the object of synchronous construction between A-D, B-E, C-F district, saves the duration.
Be only the preferred embodiment of invention described in upper, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
