Abstract

The utility model relates to a double-sided superimposed sandwich heat-insulating parapet, which comprises a precast concrete outer leaf wall, a precast heat-insulating plate and cast-in-place concrete; the parapet and the wall body below the parapet adopt an integrated prefabricated concrete outer leaf wall; prefabricating the heat-insulation board as a prefabricated inner leaf board of the parapet; cast-in-place concrete is integrally poured in the parapet, the wall body below the parapet and the floor slab. For traditional outer heat preservation parapet: the heat insulation layer is arranged in the concrete outer leaf wall, so that the risk of falling of the outer heat insulation layer is reduced; the heat-insulating layer is combined with the structure, so that the service life is long, and the economic benefit is increased; the formwork supporting and painting of the inner wall and the outer wall are avoided, the working procedures of formwork supporting and reinforcement of the parapet are reduced, and the construction efficiency is improved. Relative to sleeve sandwich heat preservation wall: the concrete is integrally poured, the structure is self-waterproof, and the waterproof problem and the cold and hot bridge effect at the abutted seam are reduced; grouting is not carried out, the grouting sleeve has higher grouting requirement, and the construction quality cannot be ensured; and automatic assembly line production is adopted, a die does not need to be customized, and energy conservation and emission reduction are realized.

Description

Double-sided superimposed sandwich heat-insulation parapet

Technical Field

The utility model relates to a two-sided coincide sandwich heat preservation parapet belongs to prefabricated component technical field.

Background

The existing double-sided laminated sandwich heat-insulation parapet has the problems that the risk of falling of external heat insulation is caused by arranging a heat-insulation layer on the outer side of a prefabricated wall body, or the floor slab pouring and the parapet pouring are carried out twice, so that the process is complicated.

Disclosure of Invention

The utility model aims at: the double-sided overlapped sandwich heat-insulation parapet is provided, the heat-insulation layer is arranged in the concrete outer leaf wall, the risk of falling off of the outer heat-insulation layer is reduced, the heat-insulation layer is combined with the structure, and the service life and the economic benefit are prolonged; simultaneously, realize concrete monolithic placement, the structure is from waterproof, reduces the waterproof problem and the cold and hot bridge effect of piece department, also need not secondary hoist and mount parapet simultaneously, reduces construction process.

The utility model adopts the following technical proposal:

a double-sided superimposed sandwich heat-insulating parapet comprises a precast concrete outer leaf wall 1, a precast heat-insulating plate 7 and cast-in-place concrete 3; the parapet and the wall body below the parapet adopt the integrated precast concrete outer leaf wall 1; the prefabricated heat-insulation plate 7 is used as a prefabricated inner leaf plate of the parapet wall; and the cast-in-place concrete 3 is integrally poured in the parapet wall, the wall body below the parapet wall and the floor slab.

Preferably, the inner side of the precast concrete outer leaf wall 1 is provided with an insulation board 2.

Preferably, a plurality of pulling pieces 4 are transversely arranged in the double-sided overlapped sandwich heat-insulating parapet at intervals.

Preferably, the double-sided laminated sandwich heat-insulating parapet is not provided with an external heat-insulating layer.

Further, the plurality of pulling pieces 4 are arranged at equal intervals.

Furthermore, the top of the precast concrete outer leaf wall 1 is bent inwards and covers the heat insulation board 2.

The beneficial effects of the utility model reside in that:

1) for traditional outer heat preservation parapet: the heat insulation layer is arranged in the concrete outer leaf wall, so that the risk of falling of the outer heat insulation layer is reduced; the heat-insulating layer is combined with the structure, so that the service life is long, and the economic benefit is increased; the formwork supporting and painting of the inner wall and the outer wall are avoided, the working procedures of formwork supporting and reinforcement of the parapet are reduced, and the construction efficiency is improved.

2) Relative to sleeve sandwich heat preservation wall: the concrete is integrally poured, the structure is self-waterproof, and the waterproof problem and the cold and hot bridge effect at the abutted seam are reduced; grouting is not carried out, the grouting sleeve has higher grouting requirement, and the construction quality cannot be ensured; and automatic assembly line production is adopted, a die does not need to be customized, and energy conservation and emission reduction are realized.
