Abstract
The utility model provides a hollow aerated concrete building block, and the middle part of the building block is provided with a cavity; the building portion on the external part of the cavity is the foaming micro pores structure-shaped, and the cavities can be respectively arranged, or a plurality of cavities can be arranged at intervals; the volume of the cavities is the one fifth to the one second of the volume of the building blocks; the core rod can be embedded and poured, and the core rod can be extracted after condensation to form the cavity.
Description
The utility model relates to a kind of construction, particularly a kind of hollow air-entrained concrete building block of doing the enclosure wall use in the building of frame construction.
At present, in industry and civilian construction widely used air-entrained concrete building block be a kind of with calcareous material and silicon materials be basic components, chemically form many air hole structures, obtain the artificial stone material of lightweight of certain intensity by steam press maintenance, it can be divided into 6 unit weight ranks and corresponding with it 5 intensity ranks with the difference of Unit Weight.See GB11968-89 for details.
Produced the air-entrained concrete building block of different stage, be the increase that realizes pore in the concrete with the consumption that strengthens foaming agent in the past, and to reach different stage weight, the existing problem of this concrete block is:
1,, and then causes the mould that collapses, ratio of briquetting is reduced and cost rises because after the foaming agent consumption strengthened, pore can increase, and pore has then caused the increasing of buoyancy in the slip after increasing.
2, because ratio of water to material is bigger, make its sclerosis slow, curing time extends and the production efficiency reduction.
3, pore gathers greatly block strength is greatly reduced, so breakage rate is bigger in maintenance, carrying, handling process.So can only use as heat insulating material.
4, thick fiber crops of its appearance and easily fall quarrel have brought difficulty for the construction of surface layer.
Owing to above reason,, promptly can not produce the block that air-entrained concrete building block below 5 grades is used for enclosure wall and build so present domestic most aero-crete factories can not produce low unit weight air-entrained concrete building block.Therefore, have to adopt the building block of the high unit weight more than 5 grades, this not only makes, and building weight strengthens, load increases, and gives its Intensity Design, and the design and construction of ground has brought very big difficulty.Cost is greatly improved.In addition, the increase of building block unit weight had both caused the unnecessary waste of material, had also caused a large amount of building blocks in lifting, unloaded the waste of the transport power in the fortune process and the increase of freight charges.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and a kind of have under the guaranteed strength prerequisite lower unit weight, production efficiency height, hollow air-entrained concrete building block that cost is low are provided.
The purpose of this utility model is to realize by following technical scheme, offer vestibule at the building block middle part, building block beyond the vestibule part partly is the micro-pore structure of foaming, vestibule is single and offers or a plurality ofly offer separately, the shared volume of vestibule should be 1/5～1/2 of a building block cumulative volume, vestibule utilize pre-buried plug, after pour into a mould, treat that its back of condensing extracts plug out and form.
Therefore: remarkable result of the present utility model is:
1, guaranteeing under the block strength prerequisite plug of pre-buried different size as required, therefore, can obtain each different rank building block of needed unit weight, to satisfy in the builing industry needs to low unit weight building block.
2, because it is in light weight and enough intensity arranged.Therefore, can reduce the load-bearing of building greatly, reduce in building intensity the design difficulty on the ground.And can reduce building cost greatly.
3, save material.
4, cracky not in building block transportation and the handling process, utilization rate improves.
5, have higher production efficiency and yield rate stable and that be easy to control.
6, have insulation and soundproof effect preferably.
Structure of the present utility model realizes by the following examples and accompanying drawing thereof.
Fig. 1 is a structural perspective of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the section of structure of the utility model embodiment 2.
Fig. 4 is the section of structure of the utility model embodiment 3.
Below in conjunction with accompanying drawing 1-4 concrete structure of the present utility model is described in detail.
It is the autoclaved lightweight concrete of cuboid that the utility model has a profile, it is characterized in that: be provided with vestibule 1 at cuboid building block middle part, all the other cross sections 2 of vestibule 1 are the aerating structure that has air chamber, and the volume of vestibule 1 accounts for 1/5 to 1/2 of cuboid building block cumulative volume.Referring to Fig. 1 to Fig. 4
Architectural feature of the present utility model also is:
The hole shape of vestibule 1 is circular hole or rectangular opening, vestibule 1 offering to separately or gang up and offer in the cuboid building block.Referring to Fig. 3 to Fig. 4
The volume of vestibule accounts for 1/3 to 1/2 of cuboid building block cumulative volume.
To further specify the utility model for example below.
The unit weight of the existing air-entrained concrete building block of example 1:06 level unit weight is the 600-630/ cubic meter, be of a size of to produce monolithic that its weight is 17.28kg the building block of 600x240x200mm, hollow when being designed and sized to 0.6x0.14x0.1, hollow parts is 0.0084 cubic metre, its hollow parts unit weight is 600kg/ cubic meter x0.0084 cubic meter=5.04kg, its volume to weight ratio is 5.04 ÷ 17.28=29%, promptly near 1/3.
Example 2: be increased to the size building block of 0.6x0.6x0.24 as size, its building block heavily is 51.84kg, the hollow parts size Selection is at 0.6x0.6x0.14, its capacity is 21.7kg, volume to weight ratio then is 42%, and actual weight smooth be 30.14kg, its weight can be reduced to below the 350kg/ cubic meter from existing 600kg/ cubic meter, be that the unit weight rank can be reduced to 03 grade from 06 grade, intensity, size then remain unchanged.
This novel key is exactly partly to reduce weight, guarantee under the topic, to satisfy intensity and instructions for use under the topic before reduction aerating part unit weight within reason before the profile size constancy with cavity.
