the invention aims to provide a heat-insulating layer structure which can resist the roof heat-insulating layer from being compressed and thinned under the action of roof load, prevent a concrete protective layer from non-uniform settlement, cracking and water seepage and reduce the maintenance frequency and the maintenance cost, and a pouring method of a heat-insulating waterproof roof adopting the heat-insulating layer structure.
The heat-insulating layer structure is realized by the following steps that the heat-insulating layer structure comprises a heat-insulating layer and a plurality of supporting columns arranged in the heat-insulating layer, wherein the supporting columns are inverted umbrella-shaped, the bottom surfaces of the supporting columns are flush with the bottom surface of the heat-insulating layer, and the upper ends of the inverted umbrella-shaped supporting columns penetrate out of the heat-insulating layer.
The top of the support column is provided with a cap.
The support column is made of one of polypropylene, nylon and ABS.
The supporting columns are distributed longitudinally and transversely or in a plum blossom shape and are uniformly distributed in the heat insulation layer.
The pouring method of the heat-insulating waterproof roof adopting the heat-insulating layer structure is realized by sequentially laying a waterproof layer, a heat-insulating layer and a concrete protective layer on a finished layer structure layer, and is characterized in that the heat-insulating layer adopts the heat-insulating layer structure, and the top of the upper end of an inverted umbrella-shaped support column of the heat-insulating layer structure, which penetrates out of the heat-insulating layer, extends into the poured concrete protective layer and is fixedly connected with the concrete protective layer.
The plurality of support columns are uniformly distributed in the heat preservation layer, so that the gravity of the concrete protection layer and the uneven live load in the use process can be transmitted to the waterproof layer through the support columns, the gravity of the concrete protection layer and the uneven live load in the use process are prevented from directly acting on the heat preservation layer, the heat preservation layer is easily compressed and thinned under the long-term action, the performance of the heat preservation layer is reduced or the heat preservation layer is made to lose efficacy, and the concrete protection layer is enabled to be unevenly settled, seep and cracked. The supporting columns are distributed longitudinally and transversely or in a plum blossom shape and are uniformly distributed in the heat-insulating layer, so that the gravity of the protective layer and the uneven live load in the using process are effectively and uniformly distributed on the supporting columns.
Compared with the prior art, the invention has the advantages of resisting the roof heat-insulating layer from being compressed and thinned under the action of roof load, preventing the concrete protective layer from non-uniform settlement, cracking and water seepage, and reducing the maintenance frequency and the maintenance cost.

Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings and examples:
as shown in fig. 1, the insulating layer structure a of the present invention is realized by including an insulating layer 1 made of one of foamed rigid polyurethane and rigid polystyrene board, and a plurality of supporting columns 2 disposed in the insulating layer 1, as shown in fig. 1 and 3, the supporting columns 2 are in an inverted umbrella shape, a bottom surface 201 of the supporting columns is flush with a bottom surface of the insulating layer 1, and top portions 202 of upper ends of the inverted umbrella-shaped supporting columns 2 penetrate out of an upper surface of the insulating layer 1.
The material of the heat-insulating layer 1 is a foamed hard plastic plate comprising one of a foamed hard polyurethane plate and a foamed hard polystyrene plate, so that when cement mortar is poured, the pouring of the concrete protective layer of the cement mortar is completed by utilizing the initial rigidity of the hard plastic plate when the cement mortar is new.
As shown in fig. 1, the top 202 of the support column 2 is provided with a cap 3. The cap 3 is screwed on the top 202 of the support column 2 and is matched with the plate 203 at the bottom of the inverted umbrella-shaped support column 2 to be fixed on the heat-insulating layer 1.
As shown in fig. 1, the bottom plate 203 of the inverted umbrella-shaped supporting column 2 is tapered, so that the force received by the vertical rod 204 of the inverted umbrella-shaped supporting column 2 is effectively and firmly transmitted to the bottom plate 203 and the inverted umbrella-shaped supporting column 2 has good rigidity.
The support column 2 is made of one of polypropylene, nylon and ABS.
As shown in fig. 2, a plurality of supporting pillars 2 are distributed in a longitudinal and transverse manner, and are uniformly distributed in the heat insulating layer 1.
As shown in fig. 4, the method for pouring the heat-insulating waterproof roof using the heat-insulating layer structure according to the present invention includes sequentially laying a waterproof layer 5 and protecting (using a cement mortar layer or geotextile 501 for protection) on a finished layer structure layer 4 (the surface of which is leveled by a cement mortar layer 401), laying a heat-insulating layer structure a, and finally laying a steel mesh and pouring a fine-grained concrete protective layer 6, and is characterized in that the heat-insulating layer structure a is the heat-insulating layer structure according to the present invention, the top 202 of the upper end of the inverted-umbrella-shaped support column 2 of the heat-insulating layer structure a of the present invention extends into the poured concrete protective layer 6 and is fixedly connected with the concrete protective layer 6, and the bottom surface 201 of the inverted-umbrella-shaped support column 2 of the heat-insulating layer structure a of the present invention is tightly pressed on the waterproof layer 5.
The waterproof layer 5 is protected by a cement mortar layer or geotextile 501, and the reverse umbrella-shaped support column 2 is prevented from directly acting on the waterproof layer 5 to damage the waterproof layer.
The cap 3 provided to the top 202 of the support column 2 increases the contact area of the top 202 of the support column 2 with the concrete cover 6, thereby effectively receiving the downward force transmitted from the concrete cover 6.
