Abstract
The utility model relates to a large-section super-high steel-rib bare-concrete double-column construction mould plate which structurally comprises two chamfer arc-shaped steel moulds, two straight-plate steel moulds and a deformation joint wood mould. The deformation joint wood mould is installed between adjacent double columns, and the chamfer arc-shaped steel moulds are installed on two opposite edges of the adjacent double columns. The straight-plate steel moulds which serve as extended moulds of the chamfer arc-shaped steel moulds and the deformation joint wood mould are formed into a T shape and installed on two lateral edges of the adjacent double columns, and the two ends of the chamfer arc-shaped steel moulds are fixedly connected with the straight-plate steel moulds through inclined pull threaded rods. Accordingly, the mould plate guarantees that opposite pull bolt holes do not exist. If a reasonable construction method is applied, especially if attention is paid to the pouring speed, delaminating thickness and vibration sequence from the perimeter to the center during the concrete pouring process, residual bubbles can be reduced. After the mould plate is disassembled, the surfaces of the concretes are smooth, and the quality of the concretes and the formed appearance are good, thereby satisfying the requirement of bare concretes. In addition, because the mould plate is reasonable in design, the efficiency of mould plate assembling and disassembling is greatly improved. The mould plate is most suitable for the large-section super-high steel-rib bare-concrete double-column construction.

Description of drawings
Accompanying drawing 1 is a kind of cross section structure schematic diagram of twin columns construction formwork of the present utility model;
Accompanying drawing 2 is a kind of structural representations of chamfering arc punching block of the present utility model;
Accompanying drawing 3 is a kind of structural representations of straight slab mould of the present utility model.
The specific embodiment
Referring to accompanying drawing 1,1 among the figure is two chamfering arc punching blocks, and 2 is two straight slab moulds, the 3rd, and the deformation joint wooden model, the 4th, two the adjacent twin columns waiting to build clear-water concrete that surrounded by template, the 5th, tiltedly draw screw rod.Heavy in section of the present utility model superelevation reinforcing bar clear-water concrete twin columns construction formwork, its structure comprises two chamfering arc punching blocks 1, two straight slab moulds 2 and deformation joint wooden models 3, described deformation joint wooden model 3 is contained between the adjacent twin columns 4, chamfering arc punching block 1 is contained on two opposite side of adjacent twin columns 4, straight slab mould 2 is contained on two sides of adjacent twin columns 4 as 3 one-tenth T fonts of prolongation mould and deformation joint wooden model of chamfering arc punching block 1, and chamfering arc punching block 1 usefulness tiltedly draws screw rod 5 to fixedly connected with straight slab mould 2 from two ends.The piece of chamfering arc punching block 1 and straight slab mould 2 preferably is located at the place, point of contact of circular arc and straight line.
The structure of described two chamfering arc punching blocks 1 comprises chamfering curved plate 1-1, vertical rib channel-section steel 1-2 and at least two transverse channel steels 1-3, wherein, two chamfering curved plate 1-1 medial surface bucklings become corresponding with two opposite side and the adjacent chamfering of default twin columns 4 respectively, vertical rib channel-section steel 1-2 vertically distributes and is welded on the lateral surface of chamfering arc steel facing 1-1, transverse channel steels 1-3 cross direction profiles also is welded on the lateral surface of vertical rib channel-section steel 1-2, transverse channel steels 1-3 two ends are respectively equipped with and tiltedly draw nut 1-4, and its structure as shown in Figure 2.Described two straight slab moulds 2 comprise steel plate 2-1, vertical rib channel-section steel 2-2 and at least two transverse channel steels 2-3, wherein, vertical rib channel-section steel 2-2 vertically distributes and is welded on the lateral surface of steel plate 2-1, transverse channel steels 2-3 cross direction profiles also is welded on the lateral surface of vertical rib channel-section steel 2-2, transverse channel steels 2-3 two ends are respectively equipped with and tiltedly draw nut 2-4, and its structure as shown in Figure 3.Chamfering arc punching block 1 is through tiltedly drawing nut 1-4 with tiltedly drawing screw rod 5 to be fastenedly connected through tiltedly drawing nut 2-4 and straight slab mould 2, and its structure as shown in Figure 1.For the ease of removing, described deformation joint wooden model comprises wooden form and gripper shoe, and wooden form is contained on the deformation joint both sides, and gripper shoe is supported between the wooden form.As building the clear-water concrete twin columns body that lateral sizes does not wait, the size of straight slab mould 2 can be made adaptability revision and get final product.
When concrete pouring construction is operated, should note deformation joint concreting, practicable symmetrical blanking, symmetry is vibrated, pay special attention to the concreting time, control concrete speed of perfusion and lift height, concreting speed preferably was controlled at 3m/ hour, about layer height 2m, want during concrete vibrating evenly, on vibrating during layer concrete, should insert lower-layer concrete 50mm～100mm, to eliminate the loose contact between two-layer, must before the lower-layer concrete initial set, carry out the every layer concrete vibrating spear insertion depth of strict control simultaneously, when guaranteeing on vibrating layer concrete, vibrating spear inserts down that layer depth is no more than 200mm, therefore vibrates at every layer concrete and finishes back reply vibrating spear and identify, with convenient grasp vibrating spear insertion depth.Earlier along the template periphery circle that shakes, from coil to coil vibrates to the center then when vibrating, and Shi Gong advantage is like this: peripheral concrete is first closely knit, when second circle and center when vibrating, the periphery concrete repeatedly is squeezed, and can reduce residual bubble, and make mortar be full of the aggregate space.Other step is identical with the job practices of ordinary concrete post.When the pillar concrete strength reaches certain intensity and can guarantee that its surface is not damaged because of stripping, just dismountable.Generally can after 24h is finished in concreting, remove, and should in time adjust striking time according to variations in temperature.It is airtight to hang up plastic sheeting immediately after the form removal, carries out moisture-keeping maintaining, and curing time is no less than 14d.As the need insulation, outside plastic sheeting, can cover straw screen or mat or straw bag.After the form removable, should be immediately to the template scrubbing of polishing, brushing clear-water concrete dedicated templates lacquer, turnover is used.
After the form removal, the concrete smooth surface, concrete quality and molded appearance are good, twin columns gap width unanimity, the two sides is smooth in the seam, and the seam faulting of slab ends is less than 2mm, slit twin columns linea angulata bar is vertical, parallel, the mould phenomenon that do not have to expand, concrete formation satisfies the clear-water concrete requirement, the most suitablely carries out heavy in section superelevation reinforcing bar clear-water concrete twin columns construction and uses.
