Abstract
The utility model relates to a building material, especially a modular mandrel. The anti-compression keel frame extends out of the bottom of the core mold, and a grid support is horizontally arranged on the extending part. The utility model discloses combination formula mandrel is upper and lower structure type product, and upper portion has the resistance to compression keel frame for in the main part mandrel, and the outer lower part of main part mandrel is the net support, can be used to the hollow superstructure of T cross-section exposed structure after both make up, and this combination formula mandrel product is pluralism material and structure, and overall structure performance is good, and intensity is high.
Description
Technical Field
The utility model relates to a building material, especially a modular mandrel.
Background
At present, two types of built-in structures and exposed structures exist in cast-in-place concrete hollow floor system products, in practice, the market share of the built-in structure hollow floor system products is smaller and smaller due to the defects of the built-in structure hollow floor system products, while the exposed structure hollow floor system products become the mainstream in the market, but the existing common exposed structure hollow floor system products also have some insurmountable defects, particularly, the exposed products used in the T-section structure floor system are prefabricated cement box bodies, the products are heavy and easy to damage, the products are particularly heavy and easy to damage when in installation construction and concrete pouring, when the damage is large, the products are poured into solid plate blocks, the small cracks can also lead the moisture in the concrete to be stored in the box bodies and permeate into a ceiling, the construction of installing and scraping is seriously affected due to the long-term drying, in addition, because the bottom surface of the box bodies is difficult to be matched with the surface of a building, the concrete grout during pouring is easy to flow onto the template through seams to cause the uneven ceiling, the leveling treatment is troublesome.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a good overall structure, intensity is high and install convenient combination formula mandrel that a mould is multi-purpose.
The purpose of the utility model is realized through the following ways: a combined core mould comprises a core mould body and a compression-resistant keel frame arranged in the core mould, wherein the compression-resistant keel frame extends out of the bottom of the core mould, and a grid support is horizontally arranged at the extending part.
As a further optimization of the scheme, the core mold is of a hollow, hollow or solid box structure.
As a further optimization of the scheme, the core mold is made of metal, rubber or plastic materials.
As a further optimization of the scheme, the compression-resistant keel frame and the grid support are made of metal materials.
Compared with the prior art, the utility model discloses its advantage of combination formula mandrel is as follows:
1. the utility model discloses combination formula mandrel is upper and lower structure type product, and upper portion has the resistance to compression keel frame for in the main part mandrel, and the outer lower part of main part mandrel is the net support, can be used to in the hollow superstructure of T cross-section exposed structure after both make up, removes bottom net support and can be used to in the hollow superstructure of built-in structure again, and this combination formula mandrel product is pluralism material and structure, and overall structure performance is good, and intensity is high.
2. The utility model discloses the prefabricated bottom plate of product changes the cast-in-place bottom plate before the net support in the combination formula mandrel, and its superstructure effect is smooth level and smooth as the roof of built-in structure, because what the combination formula mandrel adopted is reserved net support and not the prefabricated bottom plate of product, floor overall structure is better, and intensity is higher, and the change of mandrel material and structure has reduced the damage of mandrel, the effectual problem of having solved solid slab and roof infiltration.
3. The utility model discloses upper portion mandrel in the combination formula mandrel can be hollow, fretwork or solid three kinds, the material or metal or plastics or rubber or other material of adoption, lower part net support be metal or other materials. The lower grid support and the upper core mould can be of an integral structure or an up-and-down combined structure and can be separated or combined.
4. The utility model discloses the filler in the hollow superstructure of combination formula mandrel for cast in situ concrete, what adopt is hollow or fretwork mandrel or solid mandrel, is formed by metal or plastics or rubber or other light material preparation, and the product dead weight is light, has alleviateed the superstructure dead weight, has saved the quantity of reinforcing bar and concrete in the floor, has reduced engineering cost.
5. The core mould has the advantages of scientific structure, good integrity, high strength, difficult damage, no need of anti-floating treatment, convenient installation, saving anti-floating materials and improving construction progress and installation quality.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings:
FIG. 1 is a schematic view of the appearance structure of the present invention;
FIG. 2 is a schematic sectional view of the present invention;
in the figure, a core mould 1, a compression keel frame 2 and a grid support 3.
Detailed Description
As shown in fig. 1 and 2, the combined core mold of the present invention comprises a core mold 1 body and a compression-resistant keel frame 2 disposed in the core mold 1, wherein the compression-resistant keel frame 2 extends from the bottom of the core mold 1 and is horizontally installed with a grid support 3 at the extending portion.
The core mould 1 is a hollow, hollow or solid box structure. The core mould 1 is made of metal, rubber or plastic materials. The compression-resistant keel frame 2 and the grid support 3 are made of metal materials, and reinforcing steel bars of the grid support 3 exceed the core mold by about 10 centimeters or are flush with the core mold.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without the changes or substitutions thought by the inventive work within the technical scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
