Abstract
The utility model relates to a large-scale prefabricated part core model which comprises a body, wherein the section of the body is in an inverted convex shape. A group of reinforced battens are arranged inside the body. Reserved cones are arranged on the side face of the body. A reserved pulling rod is arranged between two relative reserved cones. The large-scale prefabricated part core model has the advantages that the body and the reinforced battens are combined to form a stable whole, and the whole is staggered from a concrete vibration hole and a reserved high-strength pulling rod, placement of core models is more reasonable, next process of construction can be conducted conveniently, labor efficiency is improved, supporting capacity is improved due to the fact that manufacture procedure of combination of concrete and U-steels is adopted, subsidence of the core model is effectively controlled and floating of the core model is effectively prevented by combining section steels and pouring weights.
Description
Technical field
The utility model relates to a kind of core, and especially a kind of Large Precast Members core for the diesel engine platform construction belongs to the nuclear power construction technical field.
Background technology
The long 11.8m of diesel power generation platform in the nuclear power projects emergency diesel-oil machine factory building, wide 5.9m, high 3.68m, heavily about 377 tons, the centre is the reversed convex type perforated holes of Breadth Maximum 2.96m, local height 1.8m, the structure that its deadweight is stretched out by both sides is born.As Large Precast Members, the platform core has following shortcoming in construction:
1, the perforated holes shape in the middle of the diesel power generation platform is unique, and size is larger, and is not high in the stability of manufacturing process core mould, so that the diesel power generation platform that the very solidifying soil of primary concreting makes is undesirable;
2, the core layout is unreasonable, causes the site operation difficulty large, and causes easily core mold structure to destroy;
3, core generally adopts concrete pad to support, because the core size is large, from great, especially the thick Bars In Poured Concrete Slab of core load one deck 800mm makes its support difficulty large, and core sinks easily;
4, because core size and volume are large, can produce larger buoyancy to the core left and right sides in the bottom concrete casting process, cause easily the core come-up, the anti-floating dynamics of core is not enough, causes the core come-up.
The utility model content
The purpose of this utility model is: for the problem that above-mentioned prior art exists, propose a kind of simple in structure, the Large Precast Members core of convenient and quick construction.
In order to reach above purpose, Large Precast Members core of the present utility model, its improvements are, comprise that the cross section is the body of reversed convex type, be provided with one group in the inside of described body and reinforce flitch, be provided with the reservation centrum in the both sides of described body, between the two relative reservation centrums reservation pull bar be set.
It is to be shaped with one group of concrete vibrating hole on the described body that the utility model further improves.
The utility model further improves, and described core is connected by one group of body and forms, and is provided with channel-section steel at the joint of two adjacent block bodies, and described body is provided with one group of concrete pad.
The utility model further improves, and is provided with shaped steel above described body, and the both sides of described shaped steel are connected with pouring weight by bottle gouard moved by hands.
The utility model has the advantage of: Large Precast Members core of the present utility model adopts body to be combined with the reinforcing flitch and forms a stable integral body, and with the concrete vibrating hole, reserve high-strength pull bar and stagger, the layout that is core is more reasonable, so that next procedure construction, improved efficiency, the processing procedure mode that adopts in addition concrete to combine with channel-section steel has improved enabling capabilities, effectively control core, shaped steel and mass combination have prevented again the core come-up efficiently.

The specific embodiment
Embodiment one
The Large Precast Members core of present embodiment, its structure as shown in Figure 1, comprise the body 1 that three cross sections are reversed convex type, three block bodies 1 connect, be 1.8m so that the Breadth Maximum of core is 2.96m, local height, be provided with one group in the inside of body 1 and reinforce flitch 2, wherein reinforcing flitch 2 is 120 * 40mm, in order to increase the stability of core mold structure, it is closeer in body 1 internal placement to reinforce flitch 2, so that the core inner space is less, the horizontal spacing of reinforcing between the flitch 2 is 250mm, and longitudinal pitch is decided on the structure of core; Be provided with reservation centrum 3 in the both sides of body 1, arrange between the two relative reservation centrums 3 and reserve pull bar 4, reserve centrum 3 during installation and will stagger with external mold secondary joist position with reservation pull bar 4, to satisfy the requirement of core reinforcing.
In addition, the end face of body 1 and bottom surface are shaped with one group of concrete vibrating hole 5(and see Fig. 2), make the pouring concrete of core below more closely knit, the layout in concrete vibrating hole 5 not only will stagger and reinforces flitch 2 and reserve pull bar 4 during construction, can't conflict mutually with the steel sleeve position of core top, be conducive to like this improve the pouring quality of platform; Joint at two adjacent block bodies 1 is provided with channel-section steel 6, and the bottom surface of body 1 also is provided with one group of concrete pad 7(and sees Fig. 3), the concrete pad 7 support core that matches with channel-section steel 6 can prevent effectively that core from sinking in work progress, avoid producing and partially draw; And the top of body 1 is provided with shaped steel 8, and the both sides of shaped steel 8 are connected (see figure 4) by bottle gouard moved by hands 9 with pouring weight 10, prevents work progress core mould come-up, produces and partially draws.
In addition to the implementation, the utility model also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
