Thin wall tyre case for cast-in-place concrete filling and method of manufacturing the same

Abstract

The present invention discloses a cast-in-situ concrete filling thin-wall tyre and its manufacturing method; firstly, hydration reaction mixtures such as wet loose cement mortar and lightweight cement mortar and the like are adopted to make a tyre soleplate and four side walls, all of which are integrated together; one or more than one bottom hole is arranged on the tyre soleplate; a vertical pylome tube is laid in each bottom hole correspondingly; a casting hole tube is made inside the pylome tube; then an inner model supporting plate is supported and laid on the top of the pylome tube; a pylome which is communicated with an inner hole of the casting hole tube is made on the inner model supporting plate; then the hydration reaction mixtures such as the wet cement mortar and the light cement mortar are coated on a top surface of the inner model supporting plate to make a top plate of the thin-wall tyre; during molding, the top plate is formed in one piece with the corresponding four side walls in a wet state into; the top plate is provided with the pylome which is communicated with the inner hole of the casting hole tube, and then the soleplate the four side wall and top plate are hardened to be integrated through static maintenance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thin-walled carcass for filling cast-in-place concrete and a manufacturing method thereof. Background technique [0002] In the production or construction process of reinforced concrete hollow slabs, some lightweight materials are filled in the concrete to reduce the weight of the structure and improve the thermal insulation, heat insulation, and sound insulation effects of the concrete. Most of the filler blocks are hollow. Thin-walled box, this kind of thin-walled box is also provided with concrete pouring holes through the top and bottom plates of the thin-walled box to facilitate pouring and improve its mechanical performance. Due to the limitation of the demoulding process, the inner cavity of the existing thin-walled box cannot be formed by the demoulding or pouring process at one time, so the existing thin-walled box is made of multiple prefabricated wall pane...

Problems solved by technology

[0004] But still there is defective in said method: the cavity formwork member of its one side opening is made in advance, and finally forming wall is post-fabricated, even if material is identical, but the slurry of final forming wall is with hardened surrounding side when forming The physical and chemical properties of the wall are very different, and the wall with asynchronous hardening speed cannot be integrated with the surrounding side walls. Therefore, the final forming wall and the surrounding side walls are still two different components in the manufactured cavity formwork. , the above-mentioned manufacturing method can only ensure the tight combination of the final formed wall and the surrounding side walls, but cannot realize the real one-piece combination

But the pouring hole pipe that is set in the existing thin-walled carcass and the cavity in the thin-walled carcass are closed, after concrete pouring, will form in the pouring hole pipe in the thin-walled carcass and isolate the cavity of the thin-walled carcass Solid concrete column, and the concrete column is integrally connected with the top and bottom of the reinforced concrete hollow slab, the noise in the pouring hole hollow slab and the floor below is easily transmitted along the concrete column in the pouring hole tube, because the tube wall of the pouring hole tube The same sound insulation material as the surface of the matrix is ​​used, and the wall of the closed pouring hole tube isolates the sound transmission between the concrete column and the cavity of the matrix, and the noise transmitted in the concrete column in the pouring hole tube will not be eliminated. The cavity in the wall carcass absorbs, and the noise is more easily transmitted by the concrete column in the pouring hole tube, so the structure of the pouring hole tube in the existing thin-walled carcass reduces the sound insulation effect of the thin-walled carcass for filling
