The specific embodiment
As shown in Fig. 1-Fig. 4 for building the concrete casting device of column, construction formwork 4 is formed by injection molding by the polypropylene of weight portion 85, the mixture of glass fibers of weight portion 15, the side that the main board of construction formwork 4 deviates from concrete surface has crisscross strengthening rib strip, wherein the strengthening rib strip at main board edge has respectively at least more than one waist through hole 6, and the middle part of construction formwork 4 has conical through-hole.The side of construction formwork 4 is 45 degree, and upper is 90 degree below, and the adjacent side of four construction formworks 4 is locked by the handle 1 through waist through hole 6 formation one rectangle that links together and built device, is applicable to tetragonal column and builds.In the time need to increasing the height of concrete casting device, can increase in one end of construction formwork 4 corresponding construction formwork 4, upper and lower construction formwork 4 also links together by handle 1 locking through waist through hole 6, referring to Fig. 5 and Fig. 6, the strengthening rib strip of described waist through hole 6 simultaneously has for handle 1 obliquity prominence platform 8 of two construction formwork 4 lockings, handle 1 is put more loose in rotation starting bit, after rotation, under the effect of obliquity prominence platform 8, improve constantly tension force, two construction formworks 4 are compressed, the side of construction formwork 4 is 45 degree, on be below 90 degree, can make its junction increase contact area, building Shi Bulu slurry.Screw rod 3 passes the conical through-hole of relative two construction formworks 4 and between two construction formworks 4, has the stay pipe 5 of hollow cavity, be positioned at the spiral shell dish 2 that has been threaded on the screw rod 3 in construction formwork 4 outsides, between construction formwork 4 and spiral shell dish 2, also there is stiffening girder, the corresponding screw rod of stiffening girder 3 positions have through hole or the groove passing through for screw rod 3, U-shaped groove for example, screw rod is through after the through hole or groove of stiffening girder, by spiral shell dish 2, stiffening girder and construction formwork 4 are linked together, when concrete is tamped, stiffening girder plays reinforcement effect, pressure while making device can bear concrete compacting.By rotation spiral shell dish 2, relative two construction formworks 4 and stiffening girder are locked and located; rotation spiral shell dish 2 is by after construction formwork 4 and stiffening girder locking positioning; at the two ends of screw rod 3, put protective jacket 9; protective jacket 9 have protection constructor safely, prevent the effect that screw rod is polluted by concrete; make when being repeatedly used; spiral shell dish 2 and screw rod 3 still can be used, and protective jacket 9 has the internal thread coordinating with screw rod 3.The conical through-hole of construction formwork 4 is larger in the aperture of the one side with concrete Surface Contact, and the two ends of stay pipe 5 are the pyramidal structure coordinating with described bellmouth, when relative two construction formworks, 4 locking, can fit with described bellmouth well; Construction formwork 4 is not installed the unnecessary conical through-hole of screw rod spiral shell dish locking device, with plug 7, blocks, and plug 7 is taper, and microcephaly one end has a U-shaped groove, has certain elasticity, after conveniently installing and preventing from installing, comes off.Because using handle 1 and screw rod spiral shell dish locking device, there is the equal convenience and high-efficiency of installation and removal, construction formwork 4 is repeatedly reusable.Stay pipe 5 is played a supporting role when screw rod and spiral shell dish tension template, can prevent the undue tension of template and be out of shape, and its length arranges as required, and this pipe is running stores, after construction, stays in concrete and does not take out.
What in other embodiments, concrete casting device can be for as shown in Figure 7 is U-shaped; Or circle as shown in Figure 8.
In other embodiments, shown in Fig. 4, adjacent two construction formworks add the construction formwork of the formation new structure being made of one man-hour, the both sides shape of each construction formwork has angle, and column concrete casting device can be spliced by the construction formwork of two new structures.The preferred right angle of described angle, the length of side of both sides is preferably isometric.
In other embodiments, construction formwork 4 can select at least one polymer in the polypropylene of weight portion 80 ~ 90, polyethylene, ABS resin, Merlon or polyamide and the mixture of glass fibers of weight portion 10 ~ 15 to be formed by injection molding, and also can be other material.All can meet the Performance and quality requirement of construction formwork.
Obviously, the utility model is not limited to above preferred embodiment, also can be in the spirit of the utility model claims and manual restriction, carry out conversion and the improvement of various ways, can solve same technical problem, and obtain the technique effect of expection, therefore do not repeat.Those of ordinary skill in the art can be from the disclosed content of the utility model directly or all schemes of associating, as long as within the spirit limiting in claim, also belong to protection domain of the present utility model.
