Abstract

The utility model relates to a roof heat-insulation brick which relates to the prefabricated component used for the heat insulation of the roof, comprising a brick body 1, a cavity 2 manufactured on the brick body 1, and a supporting foot 3 arranged below the brick body 1. After the roof heat-insulation brick is laid on the roof, the roof heat-insulation brick can form at least two layers of air isolated layers on the roof, and thus the heat insulation effect is better. Additionally, the utility model does not use the heat insulation materials such as the expanded perlite, the cinder, etc., and meanwhile the water proof measure which needs to be adopted for solving the water proof problem of the heat insulation materials can be saved. Thus, the utility model also has the advantages of simple structure and low cost.

Description

Roofing heat insulation brick

The present invention relates to be used in the prefabricated component of roof insulation.

China Patent No. is called the prefabricated component of " roofing heat-insulating load-bearing plate " for the name that patent provided of " 86204486 "; its structure is: the centre is the isolation layer of making of heat-barrier materials such as expanded perlite, silica, cinder or haydites, and skin is with cement, the husky totally enclosed topping of making.Its major advantage of the prefabricated component of this structure is the good and easy construction of weight capacity, but weak point is, because of cement, husky water resistance poor, and be mainly used in heat insulation use expanded perlite,

It is very high again that heat-barrier materials such as stone, cinder or haydite are made the isolation layer water absorption rate, and therefore, the isolation layer when raining in this prefabricated component will be sucked a lot of water, thereby influences effect of heat insulation.In order to solve the suction problem of above-mentioned insulating board intermediate thermal insulating layer; China Patent No. has been taked a kind of measure of making one deck waterproofing course all around again at isolation layer for " 89203003 " name is called " can the heat insulation heat-insulating roof board that can be incubated again " patent, and cement, husky topping infiltrate in the isolation layer again after sucking water when preventing to rain.This way no doubt can solve the waterproof problem of isolation layer, but it makes not only manufacturing process's complexity of this prefabricated component, and cost is also high.

The objective of the invention is to overcome the shortcoming of prior art, a kind of not only good heat-insulation effect is provided, nor with taking waterproof measure and roof insulation brick also simple in structure, with low cost and easy to manufacture.

Practice in recent years as can be known, from the effect of heat insulation angle, it is much the same that aforementioned said two kinds of heat insulation built on stilts Canton-tile floor isolation layers that use with prefabricated component and tradition are compared its effect of heat insulation.Therefore, roof insulation brick provided by the present invention will adopt the structure of air buffer.This structure shows as: it comprises on brick body, the brick body and is processed with cavity that to form air buffer, the bottom of brick body is provided with feet.After this roof insulation brick is layered on the roofing, can on roofing, form two-layer air buffer at least.Its form of structure is similar to the hollow brick that building trade is used.The present invention compared with the prior art, come heat insulation owing to forming two-layer air buffer at least after it is layered on the roofing on the one hand, therefore its effect of heat insulation is better, on the other hand, because it does not use as the heat-barrier material of types such as expanded perlite, silica or cinder and has removed the waterproof measure that will take for the waterproof problem that solves these heat-barrier materials simultaneously from, thereby it makes simple, with low cost.

What accompanying drawing provided is embodiments of the invention.

As shown in Figure 1, wherein 1 is the brick body, and 2 is the cavity on the brick body 1, and 3 for being located at the feet under the brick body 1.The material of this roof insulation layer can use cement, sand, cement, rubble or cement, flyash etc.Add the method that can adopt an extrusion modling man-hour.Certainly, also can use of the method manufacturing of sticking worker's material by first moulding, back roasting.When cavity 2 numbers on the brick body 1 are a plurality of, can become two rows to arrange (as shown in Figure 2), can form three layer of air interlayers after this brick is layered on the roofing on roofing, obviously, effect of heat insulation is better.Cavity 2 on this heat insulating tile also can be made cellular (as shown in Figure 3).

Claims

1, a kind of roof insulation brick is characterized in that it comprises brick body 1, is processed with cavity 2 on the said brick body 1, and the bottom of brick body 1 is provided with feet 3.

2, roof insulation brick according to claim 1 is characterized in that 2 one-tenth two rows of cavity on the said brick body 1 arrange.
