Description

Concrete sandwich heat-insulating wall plate

The technical field is as follows:

the utility model relates to a concrete sandwich heat preservation wallboard.

Background art:

at present, thermal insulation walls commonly used in building engineering are divided into three types, namely an inner thermal insulation wall, an outer thermal insulation wall and a precast concrete sandwich thermal insulation wall. The inner heat-insulating wall body has the problems that an inner heat-insulating layer is easy to damage, the influence of indoor decoration is large and the like, the outer heat-insulating wall body has the problems of serious fire prevention and durability, and the service life of the outer heat-insulating wall body is about 15 years generally. The precast concrete sandwich thermal insulation wall is a novel thermal insulation wall capable of realizing integration of enclosure and thermal insulation, and the wall is composed of inner and outer leaf reinforced concrete slabs, a middle thermal insulation layer and connecting pieces. The connecting piece is a key part for connecting the inner and outer leaf concrete slabs of the precast concrete sandwich heat-insulating wall body, and the stress performance of the connecting piece directly influences the safety of the wall body. The early precast concrete sandwich thermal insulation wall body mostly adopts metal lattice rib connecting pieces, and the thermal insulation property and the durability of the early precast concrete sandwich thermal insulation wall body are poor.

In addition, traditional heat preservation wallboard function singleness, more and more can't satisfy human daily needs, and the range of application reduces gradually.

The utility model has the following contents:

the utility model discloses just to above-mentioned problem, a concrete sandwich insulation wallboard is provided.

In order to achieve the purpose, the utility model adopts the following technical scheme that the plate body comprises a first concrete layer, a heat preservation layer, a second concrete layer, a sound insulation layer, a fireproof plate layer, a waterproof plate layer and a third concrete layer from outside to inside in sequence, and a plurality of FRP connecting pieces are uniformly arranged between the first concrete layer and the second concrete layer;

the heat-insulating layer is a foam glass plate, the fireproof plate layer is a gypsum fireproof plate, and the waterproof plate layer is a polyurethane waterproof plate.

The FRP connecting piece comprises connecting plate, the lantern ring and anchor bar, and the both ends of connecting plate are located first concrete layer, second concrete layer respectively in, and the lantern ring cup joints in the intraformational connecting plate outside that keeps warm, and the anchor bar is located two tip of connecting plate, and the FRP connecting piece adopts equidistance vertically and horizontally staggered formula to arrange on first concrete layer, heat preservation, second concrete layer.

The puigging includes two polyester fiber boards and inside gypsum board, still is provided with the rock wool layer between polyester fiber board and the gypsum board.

The thickness on first concrete layer, second concrete layer is 10 ~ 15mm, and the thickness of heat preservation is 7 ~ 10mm, and the thickness on puigging is 5 ~ 8mm, and the thickness on fire prevention sheet layer is 5 ~ 8mm, and the thickness on waterproof sheet layer is 5 ~ 8mm, and the thickness on third concrete layer is 6 ~ 10 mm.

The plate bodies are connected by pressing or by adhesive.

The utility model has the advantages that:

1. the utility model has the characteristics of it is effectual, fire-resistant and corrosion resisting property are strong, production and efficiency of construction are high to keep warm, can realize the structure with keep warm with life-span.

2. The utility model discloses have excellent heat preservation, syllable-dividing, resistance to compression, fire prevention, waterproof performance, the function is many, and economic benefits is showing.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

In fig. 1, 1 is a first concrete layer, 2 is a heat preservation layer, 3 is a second concrete layer, 4 is a sound insulation layer, 5 is a fireproof plate layer, 6 is a waterproof plate layer, 7 is a third concrete layer, and 8 is an FRP connecting piece.

The specific implementation mode is as follows:

as shown in fig. 1, the plate body of the present invention comprises a first concrete layer, a heat insulation layer, a second concrete layer, a sound insulation layer, a fireproof plate layer, a waterproof plate layer, and a third concrete layer from outside to inside, wherein a plurality of FRP connectors are uniformly arranged between the first concrete layer and the second concrete layer;

The plate bodies are connected by pressing or by adhesive.
