The construction technology of situ configuration wooden model: nine clamping plate → level is enclosed purlin and is adopted the reinforcing bar have circular arc or steel pipe → vertically enclose purlin to adopt steel pipe.Its advantage is that the single input cost is few, can be applicable to neatly that various planforms, plasticity are good.Its shortcoming is that apparent mass is poor behind the concrete formation, and easily loss, recycling rate of waterused are low, and it is many to drop into the labour during mounting or dismounting.When structure level number more for a long time, uneconomical not environmental protection more seems.
The construction technology of the little punching block of customizing round arc: the little punching block of circular arc → vertically enclose purlin to adopt channel-section steel → level to enclose purlin employing circular arc channel-section steel.Its advantage is that the apparent mass behind the concrete formation is better, is convenient to manpower mounting or dismounting and transportation, and the number of turnover is more.Its shortcoming is that the single input cost is higher, repeatedly has enough to meet the need the rear pattern plate easy deformation, and the labour drops into morely during mounting or dismounting, causes rough piece between the template easily.
Customize the construction technology of fixed large arc-shaped steel mould: adopt screw to connect (need not to establish in addition and enclose purlin) between the big punching block → punching block of customization.Its advantage is that the apparent mass behind the concrete formation is good, easy accessibility, and the number of turnover is many.Its shortcoming is a single input cost height, and shape of template can only modular in design, and structure adaptability is poor, and in a single day cross sectional shape changes just needs processing again, loses time and financial resources.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of circular arc metope that can adapt to variable cross-section, make full use of the many advantages of the big punching block number of turnover, when ensuring the quality of products, the large arc-shaped steel mould with adjustable width that can reduce cost significantly again is to overcome the above-mentioned defective that prior art exists.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of large arc-shaped steel mould with adjustable width, its integral body is in the arc-shaped, it is characterized in that, comprises the segmentation of some circular arc punching blocks, described circular arc punching block segmentation broad ways is interconnected to large arc-shaped steel mould, between the local two adjacent punching block segmentations stripping is set.
Further, the segmentation of described circular arc punching block interconnects and is ellipse arc; Described stripping is uniform to be arranged between the two adjacent punching block segmentations.
By above disclosed technical scheme as can be known, the present invention is by being divided into some circular arc segmentations with the big punching block of integral body, needs according to variable cross-section circular arc body of wall length, stripping is set between the circular arc segmentation at interval, run into the variable cross-section place during use and only need remove corresponding stripping, can adapt to the needs of new circular arc body of wall.
Beneficial effect of the present invention is as follows: generally speaking, the super highrise building changes of section belongs to normal phenomenon 4～5 times, the input cost of template mainly is the material input, as adopt the big mould of fixed steel then to need 4～5 cover templates, very uneconomical, adopt after the big mould of adjustable width formula steel of the present invention, can satisfy the total construction requirement once the cover template, economic benefit is very obvious.Product quality also very near fixed big punching block, can satisfy the standards of acceptance requirement fully.Avoided changing the trouble of template simultaneously, convenient construction.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment structure of the present invention is described in further details.
As shown in Figure 1, large arc-shaped steel mould with adjustable width of the present invention, its integral body is in the arc-shaped, comprise some circular arc punching blocks segmentation 1, described circular arc punching block segmentation 1 broad ways is interconnected to large arc-shaped steel mould 2, between the local two adjacent punching block segmentations stripping 3 is set, described stripping is uniform to be arranged between the two adjacent punching block segmentations.
Shown in Fig. 2～4, the segmentation of described circular arc punching block comprises that level encloses purlin 11, vertical rib 12, circular arc panel 13, vertically banded plate 14 and horizontal banded plate 15, described level encloses purlin 11 and vertical rib 12 is fixed on circular arc panel 13 back, described vertical banded plate 14 is fixed in the upper and lower end face of circular arc panel 13, described horizontal banded plate 15 is fixed in the side end face of circular arc panel 13, and wherein a level is enclosed hanger 16 is set on the purlin.
Embodiment such as certain TV transmission tower engineering, its core tube cross section ovalize, barrel thickness is contracted to 400mm gradually by 1000mm, and curvature and circular arc girth all will change after each cross-sectional constriction.Adopt large arc-shaped steel mould with adjustable width of the present invention, the average of getting core tube changes of section comes design template as benchmark, makes structural section change the error that produces and is in better controlled scope.
The big punching block of barrel should be designed to ellipse arc strictly speaking, considers the difficulty of processing, designs according to the standard circular arc near elliptic arc.In a single day steel form makes moulding, in construction, just can not adjust template curvature again, so for standard circular arc and elliptic arc shape are consistent substantially, on every section elliptic arc, get two end points and a mid point, with standard circular arc of this three dot generation, the maximum rise error of this circular arc and the oval camber line of former design is controlled in the 0.5mm, and after the barrel cross section repeatedly changes, and its rise error still can be controlled in the scope that standard allows.
Variation for elliptic arc girth behind the variable cross-section, the length that the elliptic arc girth is reduced when calculating each cross-sectional constriction, according to the width that reduces Design of length stripping template, after stripping template at every turn, the template total length all can adapt to the variation in cross section next time.Be not distorted in order to ensure the global shape of elliptic arc behind the stripping in addition or be out of shape, the template of each stripping is divided into 4 fritters, disperse to be arranged symmetrically in around the core tube, specifically as shown in Figure 1, number in the figure 4 is the separator bar of two adjacent circular arc punching block segmentations, among the figure each template segmentation with major axis as center line, bilateral symmetry, dash area stripping 3 ' is the template of next body of wall required stripping when shrinking.
