Abstract

The utility model relates to an assemble type aerated concrete segment. Dead holes (3) with the same pore diameter and depth are respectively opened on the top surface and the bottom surface of a concrete segment body (1) thereof; the dead hole on the bottom surface is positioned right under the corresponding dead hole on the top surface; the assemble type aerated concrete segment also comprises a bolt pin (2); and when the bolt pin is used, an upper segment and a lower segment thereof are respectively inserted in the corresponding dead hole on the bottom surface of an upper layer concrete segment body and the dead hole on the top surface of a lower layer concrete segment body. The assemble type aerated concrete segment is a bearing building block or a non-bearing building block, and the building block can be molded in an integral manner for one time; the aerated concrete segment has the characteristics of wide material range and good cracking resistance and anti-seismic performance; and by using the aerated concrete segment, the masonry time of a wall body can be saved greatly, the working procedure is simple, mortars are not needed, and no crack can be achieved.

Description

The assembly type air-entrained concrete building block

Technical field

The utility model belongs to constructional materials, specifically is meant a kind of assembly type air-entrained concrete building block.

Background technology

Because the production of traditional materials for wall has caused serious harm for land resources, the energy, the environment of China, the whole nation each province, city all greatly develop and promote energy-conservation, save land, sharp useless novel wall material, the building block of various materials, brick are developed use in succession.Air-entrained concrete building block was used widely at building field in recent years, found that cracking appears in the conventional air-entrained concrete building block wall that uses easily but observe a large amount of case histories.Find that after deliberation the main cause that produces the crack is: on the one hand because the air-entrained concrete building block void content is big, water absorbing capacity is strong, after the moisture of masonry mortar is siphoned away in a large number by building block, cause and condense not exclusively, intensity reduces greatly, and the tension shear behavior of mortar joint does not reach designing requirement; The coefficient of deformation of air-entrained concrete building block itself is bigger on the other hand, and the pulling force that produces owing to deformation is also just bigger, thereby has weakened the ability of body of wall shearing resistance, tension and resistance to deformation, causes wall crazing, has caused a kind of sense of insecurity to people.

The utility model content

The purpose of this utility model is, the defective at prior art exists proposes a kind of assembly type air-entrained concrete building block, and it is load-bearing or non-bearing building block, and building block can a seamless moulding; Have draw materials extensively, cracking resistance and the good characteristics of anti-seismic performance, and use this kind building block to save greatly the building wall time, operation is simple, exempts from mortar, does not ftracture.

The technical solution of the utility model is, described assembly type air-entrained concrete building block comprises building block body, its design feature is, this assembly type air-entrained concrete building block also comprises pin, the end face of described building block body has the aperture blind hole identical with the degree of depth with the bottom surface, and the blind hole on the described bottom surface be positioned at corresponding blind hole on the end face under; The quantity of the described pin during use in the end face blind hole of its upper and lower two sections bottom surface blind holes that are plugged on the corresponding upper building block body respectively and lower floor's building block body is identical with end face blind hole or bottom surface blind hole quantity.

Below the utility model made further specify.

Referring to Fig. 1 and Fig. 2, assembly type air-entrained concrete building block described in the utility model comprises building block body 1, its design feature is, the end face of described building block body 1 has the aperture blind hole identical with the degree of depth 3 with the bottom surface, and the blind hole on the described bottom surface be positioned at corresponding blind hole on the end face under; This assembly type air-entrained concrete building block also comprises pin 2, and referring to Fig. 3, described pin 2 is in use in the end face blind hole of its upper and lower two sections bottom surface blind holes that are plugged on the corresponding upper building block body respectively and lower floor's building block body.

Design principle of the present utility model is, forms pin key thereby connect by described pin between the building block, and the shearing that acts in the building block can freely transmit in horizontal direction between the building block up and down by pin; Pin and building block adopt same material to make, and various performance basically identicals, two parts can better co-operation, have inherited the good heat preservation performance of traditional air-entrained concrete building block to greatest extent, from advantages such as heavy and lights; Avoid mortar and do not reach designing requirement because moisture is siphoned away the back performance by building block; Different aggregates and proportioning can be made into the load-bearing or the non-bearing fragment of brick of varying strength.

Product of the present utility model has following advantage:

A. draw materials extensively, be convenient to large-scale promotion.The raw material of assembly type air-entrained concrete building block mainly is cement and gathers materials that the resource of these two kinds of raw materials is all very abundant;

B. cracking resistance is good, owing to adopt the pin design, has ensured that shearing at the pipeline between the building block up and down, has overcome the low common fault of traditional air-entrained concrete building block wall masonry mortar intensity, has improved the cracking resistance of body of wall;

C. anti-seismic performance is good; Connect by pin between the building block, the material of pin is with the building block unanimity, and the unity of performance has been guaranteed integrality of wall, thereby improves the anti-seismic performance of body of wall greatly;

D. high efficiency; Because building block is adopted and is exempted from mortar, assembling mode, has saved the time of building by laying bricks or stones greatly;

E. exempt from mortar assembling masonry way because building block is adopted, saved mortar greatly.
