Abstract
The utility model belongs to the technical field of civil engineering technology, and concretely relates to a quasi-elliptic section internal mold for a cast-in-place concrete hollow floor system. The key technical points are that one side wall and two end walls of an internal mold of which the cross section is quasi-elliptic break in the same plane while the other side wall is in flexible connection, and thus a box-type structure where the upper part and the lower part are openable is formed. The quasi-elliptic internal mold is treated as an openable box structure for integral manufacture, the internal mold can be conveniently stacked and transported layer upon layer when the upper part and the lower part are opened, and one quasi-elliptic section internal mold is combined when the upper part and the lower part are folded up and then is buried into concrete to form a cavity.
Description
Technical field
The utility model belongs to technical field of civil engineering, is specifically related to a kind of cast-in-place concrete hollow building roof with collapsible plan oval cross section internal mold.
Background technology
At present, cast-in-place concrete hollow structure and component application obtain more and more extensive, circular cross-section cylinder in-core mould has also obtained a large amount of uses, but in use, circular cross-section cylinder in-core mould hollowcore slab often faces Ban Ding and plate base thickness degree is inadequate or hollow rate is little problem, the patent No. discloses a kind of cast-in-place concrete hollow building roof with intending the oval cross section internal mold for the patent of " CN201120513403.8 ", this internal mold has solved the problems referred to above, but the making of above-mentioned internal mold, stacking, transportation and assembling are inconvenient; This internal mold is made integral manufacturing inconvenience of getting up, and stacks and needs a large amount of spaces, also occupies a large amount of vehicle space, inefficiency during transportation.Therefore being badly in need of a kind of new technology addresses the above problem.
Summary of the invention
The purpose of this utility model is for this cross section inconvenient for making, stacking, transportation and the assembling of intending oval internal mold, and the problem of inefficiency provides on a kind of structure and made improved cast-in-place concrete hollow building roof with collapsible plan oval cross section internal mold.
The purpose of this utility model realizes by the following technical solutions: this cast-in-place concrete hollow building roof is with collapsible plan oval cross section internal mold, be characterized in: this lateral cross section disconnects in same plane for a side wall and the end walls of intending oval-shaped hollow inner formwork, another side wall flexibly connects, thereby but forms a case structure of two parts folding up and down.
Specifically, but two parts up and down of the case structure of described folding are two parts of equal and opposite in direction, symmetry, are perhaps unequal, the asymmetric two parts of size.
For two parts up and down of making hollow inner formwork are more firm after altogether, two parts up and down of described hollow inner formwork connect by fixed connecting piece or active connection.Described fixed connecting piece adopts a kind of in welding, riveting method, described active connection to adopt a kind of in latch, bolt, rope or silk thread.
For higher being not easy of hollow inner formwork intensity is out of shape, the outer wall lateral cross section of described hollow inner formwork is provided with recessed or protruding muscle rib.
For making the hollow inner formwork outer wall be not easy under external force distortion, described hollow inner formwork the inside is provided with horizontal inner support.
Can be supported on reinforcement when hollow inner formwork is used, and open type is while stacking, piles up firmly, the upper bottom surface of described hollow inner formwork is provided with the feet of several strips.
But the utility model is intended the case structure integral manufacturing of oval internal mold as folding by handle, when up and down two parts are opened, is convenient to stack, transport, and open type is stacked layer by layer, and open type is transported layer by layer; During use, up and down two parts are folded up, and are merged into one and intend the oval cross section internal mold, then form cavity in Transducers Embedded in Concrete.Plan oval cross section internal mold of the present utility model is made and is assembled all very convenient, two parts integral manufacturing as open type,, as long as up and down two parts close up, adopt fixed connecting piece or active connection to connect during use and make up and down two parts more firm altogether during assembling.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, Fig. 1 is the transverse sectional view of the present embodiment when intending oval hollow inner formwork and closing up, and Fig. 2 is the right view of Fig. 1, and Fig. 3 is the transverse sectional view of the oval hollow inner formwork of the plan of Fig. 1 while opening, and Fig. 4 is the right view of Fig. 3.As seen from the figure, the lateral cross section of this hollow inner formwork 7 is for intending oval (approximate ellipsoidal), limit, left side wall and the rear and front end wall of hollow inner formwork 7 disconnect in same plane, right edge wall 3 flexibly connects, thereby but forms the case structure of a part 2 on it and lower part 1 equal and opposite in direction, symmetrical folding.Be also shown in from figure, two parts up and down that hollow inner formwork 7 disconnects connect by connector 4, and the connector 4 in the present embodiment is latch; The outer wall lateral cross section of hollow inner formwork 7 is provided with recessed or protruding muscle rib 6; In addition, the hollow inner formwork the inside also is provided with horizontal inner support (not shown in FIG.), this horizontal inner support is the circular member that the recessed or protruding muscle rib 6 that arranges on outer wall lateral cross section according to hollow inner formwork 7 is made, and is enclosed within or is stuck on the inwall corresponding to the hollow inner formwork at recessed or raised ribs 6 places that arrange on the outer wall lateral cross section.Be also shown in from figure, the front and back end of the upper bottom surface of hollow inner formwork 7 is respectively equipped with the feet 5 of two strips.
The macromolecular materials such as hollow inner formwork 7 employing plastics are made, upper part 2, the lower part 1 while opening wide and the right edge wall 3 that is connected, and this three part is as an integral manufacturing, be made into an open type integral inside molding, can put together by lamination when stacking and transportation, saved space, improved efficiency.During use, upper part 2, lower part 1 are superimposed together by right edge wall 3, then by connector 4, connect into integral body, form and intend oval hollow inner formwork 7.
