Abstract

The utility model relates to a heart fired brick for wall laying in building construction. The utility model is characterized in that a junction which is made from polystyrene plastic beads by heating is filled in the hole of the sintered hollow brick. The utility model does not change the original appearance and other properties of the fired brick, thereby substantially enhancing the thermal insulation and noise performance of this fired brick.

Description

Crisp core sintered brick

Technical field

The utility model relates to a kind of constructional materials, specifically is a kind of crisp heart brick that is used for building wall.

Background technology

Clinker brick is the in all age the most frequently used materials for wall of China always, still accounts for national materials for wall total amount about 80% at present.For saving soil, energy-conservation, clinker brick singly is not to make raw material with pure clay gradually, and has increased such as clinker brick kinds such as shale, gangue, flyash and mud, slags.And, for sound insulation, the heat-insulating property of improving goods, also widely popularize sintered hollow block.In recent years, country is the energy-saving effect that further improves construction wall, by revising national technical standard, with sintered hollow block by the original circular hole that is arranged in parallel, change staggered rectangle pass into, even but like this, the still difficult requirement that reaches national building energy conservation 65% in the use.For reaching best insulation, heat insulation building demand, the external technology that generally adopts is to add plastics microballon, sawdust, grass fiber fragment etc. in the brick raw material, so that form microporous brick behind the sintering, or superposeing compound with the clinker brick layering thermal insulation material, plastics etc. is the multilayer composite heat insulating brick.Though these ways have improvement greatly to insulation, the heat-proof quality of clinker brick, this tends to change structure, the shape of clinker brick, and can influence physical properties such as clinker brick resistance to compression, freeze proof and water absorption rate, has also increased the complexity and the difficulty of production technology.

Summary of the invention

The purpose of this utility model is, under the prerequisite that does not change original shape of clinker brick itself and physical property, makes the crisp core sintered brick that a kind of insulation, sound insulation value significantly improve with existing clinker brick finished product reprocessing.

The purpose of this utility model is to realize like this, in the hole of the sintered hollow block of forming by outer wall, internal-rib and hole, insert the polymer foam microballon earlier, stretch into to heat in the hole with special equipment again and make its foaming and intumescing, fill thin hole and be shaped to crisp knot, natural coagulation and make the utility model crisp core sintered brick.The polymer plastic microballon that adds in the sintered hollow block hole can be the heat insulating material that polystyrene, polyamine fat or blown rigid phenolic resins etc. are in light weight, pollution-free, the life-span is long, cost is low.Special equipment is to charge into high steam to the mode of heating of inserting thing in the sintered hollow block hole, and heating and temperature control is at 120 ℃～140 ℃.

The utility model in the hole of existing sintered hollow block hot briquetting the sound-insulating material, on the basis that does not change sintered hollow block profile and other performance, significantly improved insulation, the sound insulation value of clinker brick, after tested, the goods thermal resistance is by existing 0.4m ².k/w bring up to 0.7m ².k/w, sound insulation value has improved 5～10 decibels than originally, and not only technology is simple, pollution-free but also the goods heat-insulating property satisfies the index of the building energy conservation 65% of national requirements fully.

The specific embodiment

Sintered clay hollow brick with brick field finished product 240mm * 240mm * 115mm specification is an example, utilize the throwing section device of special equipment in brick hole (3), to insert the polystyrene plastics microballon, the nozzle of special equipment moves and aims at and insert brick hole (3) then, import 120 ℃～140 ℃ high steams, 5～10 second polystyrene plastics microballon foaming and intumescing, be shaped to the shortcake knot (4) that fills thin brick hole (3), promptly make the utility model crisp core sintered brick finished product.

Claims

1. construction walling crisp core sintered brick, it is by the outer wall (1) of brick, and the hole (3) of internal-rib of brick (2) and brick is formed, and it is characterized in that, is filled with the shortcake knot (4) with the hot briquetting of polystyrene plastics microballon in the hole (3) of brick.
