Description
Technical field
The utility model relates to constructional materials, and particularly a kind of air-entrained concrete building block that is applicable to building construction technology, this air-entrained concrete building block are applicable to on-the-spot building construction technology and close rib composite wall structure.
Background technology
Air-entrained concrete building block have material source extensively, higher, the light weight of stable material quality, intensity, be prone to processing, advantage such as cost is lower and insulation, heat insulation, sound insulation, fire resistance be good, be widely used in building bearing wall or infilled wall masonry project in recent years.Air-entrained concrete building block is a kind of constructional materials of loose structure, and its inside is uniform-distribution with countless small pores, and porosity reaches 70-80%, and an one of which key property is that water imbibition is bigger, and the deadweight of suction back significantly increases.For guaranteeing the masonry quality of air-entrained concrete building block body of wall; Regulation in China's " masonry project constructure scheme ", before the air-entrained concrete building block construction, should carry a few days ago water moistening; And when build by laying bricks or stones at the scene; It is moistening still to need to water in right amount to bricklaying surface, so just can avoid because of the air-entrained concrete building block water imbibition causes the cement mortar dehydration too fast greatly, and then cause the cracking of cement mortar mortar joint.
In actual engineering, a problem that can not be ignored is, because air-entrained concrete building block belongs to the porous type building block, its water absorbing capacity is stronger, and the deadweight of suction back increases bigger, the difficulty that has increased workman's carrying greatly and built by laying bricks or stones; Receive the restriction of odjective causes such as China's present stage construction worker self diathesis is not high, management is not in place; The building construction difficult quality of air-entrained concrete building block is well ensured; In the actual engineering; Is no lack of the minority constructor for the weight that alleviates air-entrained concrete building block and be convenient to build by laying bricks or stones and save this important operation of moistening air-entrained concrete building block of watering; Cause and adopt the infilled wall that air-entrained concrete building block builds by laying bricks or stones and the construction quality of partition wall to be difficult to guarantee, limited applying of air-entrained concrete building block.
Therefore; Need the urgent technical problem that solves of those skilled in the art to be: how to design a kind of air-entrained concrete building block, when the workman adopts on-the-spot building construction air-entrained concrete building block body of wall, need be to the air-entrained concrete building block moistening work of watering in a large number; Be convenient to construction thereby reach; Accelerate speed of application, alleviate labor strength, and the purpose that guarantees air-entrained concrete building block building wall quality.
Summary of the invention
The utility model provides a kind of special air-entrained concrete building block that is applicable to existing block construction technology; Carrying out the moistening work of need not watering in a large number when concrete block masonry is constructed; Both guaranteed the lightweight characteristic of air-entrained concrete building block; Can strengthen the interlock performance between the air-entrained concrete building block again, reduce the crack between the building block, guarantee the masonry quality of air-entrained concrete building block body of wall.
The technical scheme that the utility model adopts is:
Four sides at the gas concrete piece all are provided with dense layer, and several equally distributed grooves are set on the dense layer of each side.
The unit weight of said dense layer is 2～3 times of gas concrete piece unit weight.
The thickness of said dense layer is 5mm～30mm.
Groove on the said dense layer is along the length or the width setting of dense layer.
Said groove be shaped as rectangle, V-arrangement, arc or trapezoidal.
The degree of depth of said groove is no more than 2/3rds of dense layer thickness, and the width of groove is 10mm～100mm.
The beneficial effect of the utility model is:
(1) the utility model is directed against the design that Autoclaved aerated concrete blocks is made, and is equally applicable to other light porous building-brick, like EPS concrete block, foam concrete block, foam cement building block etc.
(2) the special air-entrained concrete building block that utilizes the utility model to design; When the workman adopts on-the-spot building construction technology to build the air-entrained concrete building block body of wall by laying bricks or stones; Need be to the air-entrained concrete building block moistening work of watering in a large number; Only need to the dense layer upper and lower surfaces and about the dense layer on surface carry out suitably moistening get final product, thereby avoided air-entrained concrete building block integral body to water problem that the deadweight of moistening back increases greatly reaches and is convenient to construct; Accelerate speed of application, alleviate the purpose of labor strength; On the other hand, the setting of groove makes that the interlock performance between building block and the building block is stronger, and cement mortar should not come off, and the overall operation property of blockwork is better, thereby has guaranteed the masonry quality of air-entrained concrete building block body of wall.
(3) the special air-entrained concrete building block of the utility model design is particularly useful for the close rib composite wall structure.The prefabricated assembled job practices of the general employing of tradition close rib composite wall structure; Prefabricated close rib composite wall board overall dimensions is bigger; Mostly its length, height are 2.7m-3.0m; Thickness is 0.2m-0.25m, and the weight of monolithic wallboard is about 2.5-3.0t, and the job site need be by large-scale hanging devices such as tower cranes.Yet; The dwelling house density in the vast rural area of China, area, cities and towns is lower, and single building building construction area is little, and the low story dwelling below three layers and three layers occupies considerable proportion; In this case; Adopting prefabricated assembled construction will bring some inconvenience, and increase expenditure of construction, is the main factor that the restriction close rib structure is used in above-mentioned area.Be the characteristics that adapt to area, villages and small towns dwelling house low layer, disperse, have a large capacity and a wide range, can adopt existing block Cast-in-situs type construction technology to build low layer close rib composite wall structure, that is to say; Adopt the on-the-spot manual air-entrained concrete building block of building by laying bricks or stones; The mode of fluid concrete girt strip rib post is built up low layer close rib composite wall structure then, therefore, adopts the special air-entrained concrete building block of the utility model design to build the close rib composite wall structure; Need be to the air-entrained concrete building block moistening work of watering in a large number; Can alleviate labor strength greatly, accelerate speed of application, have crucial meaning for the large-area applications of this energy-conservation antidetonation type structure in the area, villages and small towns.
