Description

Big vertical hole cement hollow brick

The thickness of existing small-sized cement building-block (hollow concrete block) is no more than 24 centimetres, it saves type of material most is that the outside is square, and endoporus is near square, and this one hand tile is because body of wall is thin, (using one deck when generally building wall), the sound-insulating and heat-insulating effect is bad, conducts heat soon because of it in summer, and interior temperature is too high, at cold district Winter protection weak effect, room temperature is lower, and therefore this one hand tile is difficult to apply, especially at north cold area.Increase with two-layer then its entity part, cost up is not even than the loess saving of baking bricks.The cement hollow building blocks of original a kind of thicker (24 centimetres), its endoporus is hollow to be strip, entity part is big, with the many and cost height of material, the sound-insulating and heat-insulating weak effect, if reduce cost with the way that enlarges bar hole, then its intensity sharply descends even can not use.

The purpose of this utility model is that design is a kind of equally thick with institute's (more than 24 centimetres) body of wall of building, only get final product when building a house with one deck, sound-insulating and heat-insulating is effective, it is few and cost is low to consume material, intensity meets the requirements, have easy to usely, can accelerate building speed, save building man-hour, can realize the large-scale upright hole hollow concrete block that wall is prefabricated, that is a kind of large-scale cement building-block.

What this upright hole hollow concrete block was different with the ordinary Portland cement hollow brick is: 1, it is the same wide with the wall of thicker (more than 24 centimetres) that will build, and body is twice above than little building block, 2, the hollow of this brick is vertical hole, it is big that the volume of the volume ratio ordinary Portland cement hollow brick of interstitial hole is wanted, and also greatly promptly saves material more than the little building block volume of saving most material.3, ordinary Portland cement building-block, the hollow shape of hollow brick is roughly the same with profile, or bar shaped, the shape in hollow its hole of this hollow brick can be made into from above and is seen as circle, ellipse, and rectangle and circle, the combination on oval-shaped arc limit can have a hole on the brick; Also a plurality of holes can be arranged, be divided into a row or number row, be similar to cellular.4, the hole of this brick communicates up and down, does not seal top and bottom except that being placed on that building top etc. locates.

This hollow concrete block is made arch inside in the one side of wall table, promptly a kind of prestressed structure, even outer face wall matrix section system is thinner, this brick also can have bigger compressive strength.Be inside porous, can more effectively alleviate the conduction and the convection losses of heat, weaken the propagation of sound, thereby improve the sound isolating and heat insulating performance in house.Inside not by the part of wall table can make thinner because these places are under pressure, hitting power is little, can not adopt prestressed structure, can reduce materials so as far as possible, reduces cost.

This brick can be designed to the different series of specification according to the performance need of building walls, its body is twice above than ordinary Portland cement hollow brick (building-block), be actually a kind of prefabricated wall, time spent one assembling gets final product, and smears water toward the joint portion when building wall and mixes mortar and then normal maintenance.

The shared volume of volume compression concrete of hollow hole in will as far as possible enlarging under the prerequisite that guarantees surfaces externally and internally and whole firm degree for reducing cost to greatest extent.

The place that maybe need add the house column in the corner can also in the hole, settle reinforcing bar then fluid concrete this just formed pillar with the body of wall one, the low-rise building this point is very important, it can save the moulding material of beating column, thereby makes the building costs of building lower, and building speed is faster.

This brick adds sandstone or industrial residue manufacturing with various suitable cement, mechanization production in enormous quantities, but also manual production.

The good effect that uses this brick to build the wall generation is: bake bricks than loess, ordinary Portland cement hollow brick, small-sized cement building-block have better sound-insulating and heat-insulating effect; The wall of construction same thickness is baked bricks than with loess and is reduced cost about 50%; Than small-sized cement hollow brick, the small-sized cement building-block reduces cost about 20%.Since be maximize, tandem product, realized the prefabricated of wall, can save to build and accelerate building speed man-hour, it can also energy conservation, but more utilizes the industrial residue pollution abatement.

Accompanying drawing 1-3 is three embodiment of this upright hole hollow concrete block.

Fig. 1 is that volume is 40 * 36 * 40(cubic centimetre) master of the upright hole hollow concrete block of (length * wide * height) two views of bowing, this is one to be provided with the large-scale upright hole hollow concrete block in the upright hole of three rows, the 1, the 2nd, when building wall on the two sides on wall surface.3, the 4th, be placed in the wall with other the two sides of this brick combination.

Accompanying drawing 2 is that a volume is 40 * 36 * 40(cubic centimetre) the masters of the large-scale upright hole hollow concrete block that is provided with the upright hole of two rows two views of bowing, among the figure the 1, the 2nd, the two sides of wall table, the 3, the 4th, the two sides in wall.

Accompanying drawing 3 is that a volume is the vertical view cutaway drawing of large-scale upright hole hollow concrete block in a hole of 40 * 36 * 40 cubic centimetres, among the figure the 1, the 2nd, and the west of wall table, the 3, the 4th, the two sides in the wall.

Further specify the structure and the feature of this brick below in conjunction with accompanying drawing.

Large-scale upright hole hollow concrete block shown in Figure 1 is provided with three layers of upright hole; the hollow parts volume is bigger inside; this can reduce materials; reduce cost; the structure of three layers of porous can significantly reduce the conduction of heat; convection losses; because the thickness of this brick is that the conduction heat waste rate of 36 centimetres of its entity part is lower more than 50% than the little building block below 24 centimetres; add is inside loose structure; when heat (or cold) when surfaces externally and internally influences body of wall; hole wall through surfaces externally and internally arrives the first floor hole; there is bigger hollow surface in this one deck hole; cold or hot conduction is subjected to existing in the hole partition of air; and these air are owing to be in a less space; activity is very slow; therefore its convection heat losses is very little, when the heat that has greatly been reduced by the first floor hole (or cold) through second; during three layers of hole, pass heat (or cold) in the past just seldom.Therefore the house sidings of building with the upright hole hollow concrete block of this structure and specification has good heat-proof quality, compares with the loess brick with little building block, can make indoor cool in summer and warm in winter.

Because the thicker and porous wall of body of wall is to the reflex of sound wave, this brick also has than the better soundproof effect of little building block.

At the surfaces externally and internally of wall (among the figure 1,2) the inside hole wall is an arch, this is a kind of prestressed structure, this structure can guarantee when the layer of concrete of wall approaches, still bigger compressive strength can be arranged, be enough to resist the pressure that comes from surfaces externally and internally, such structure can reduce materials, can reach requirement of strength again, its two sides inside is (among the figure 3,4) arch of no use, and the limit wall is thinner, this be because they be combine with other upright hole hollow concrete block and be positioned at body of wall inside, the pressure that is subjected to is little, therefore can not adopt the arch form prestressed structure, can certainly adopt, whole so firm degree can be better, but will use some materials more.

Arc will be made in each angle in hole inside, and should not make the right angle, and it is concentrated unfavorable to the whole soundness of brick that stress easily takes place at the right angle.

Fig. 2 is the embodiment of double-deck endoporus, and double-deck endoporus generally also can satisfy the requirement to sound isolating and heat insulating performance, just weaker than three layers of endoporus.

Because big so its materials of three layers of endoporus of volume ratio that this endoporus is hollow still less, among the figure the 1, the 2nd, be positioned at the wall surface, here hole wall is the arch prestressed structure, though its effect is approaching of outer wall system bigger compressive strength is arranged but, prestressed structure is not adopted on the two sides that is positioned in the wall, and system is thinner, this be because this two sides be placed in the wall with other brick in conjunction with after be under pressure for a short time, it also can adopt the arch prestressed structure certainly.In order to prevent the concentrated influence to the firm degree of integral body of stress, arc all will be made in the angle of endoporus.

Accompanying drawing 3 is the large-scale upright hole hollow concrete blocks in a hole, because the volume in hole is big especially, so it saves material the most, its four sides all is the arch prestressed structure, therefore all there is compressive property preferably at its four sides, and this brick is good not as preceding two kinds of sound isolating and heat insulating performances, but can insert soil in endoporus, ashes etc. improve the sound isolating and heat insulating performance in house.

Except these three kinds shown in the drawings, can also design large-scale upright hole hollow concrete block, but its form of structure is with being substantially identical described in this manual with diversified upright hole and plurality of specifications.
