Abstract

The utility model discloses a non-bearing multihole brick by blind hole sintering. The utility model belongs to building masonry elements which are characterized in hollow body and comprises a brick body (1) and holes (2). The purposes of enhancing intensity, avoiding mortar leakage, saving materials and energy, cutting the cost and reducing the fabrication cost can be obtained by adopting the structure of conical blind holes (3) or conical semi-blind holes (4). The arrangement and machining of the holes of the utility model are different from that of ordinary hollow bricks and blind hole bearing hollow bricks and the source of raw material is wide and the utility model is applicable to processes of press forming and extrusion forming.

Description

Multihole brick by blind hole sintering

It is the non-bearing building masonry component of feature with the cavity that the utility model belongs to a kind of, is specifically related to a kind of non-bearing blind hole Fired perforated bricks with the tapered blind hole structure, is used for space enclosing structure or other occasions of building.

Present both at home and abroad sintered hollow block polyphyly extrusion molding and compression moulding.Adopt the blank-making method of extrusion molding to determine existing hollow brick to be through hole; Adopting the hollow brick major part of compression moulding is the through hole hollow brick.Several years ago, a kind of bearing hollow brick with blind holes of introducing in the domestic patent documentation is flat blind hole or half flat blind hole, and only is a load bearing hollow brick that end face is a blind hole.

The purpose of this utility model provides the blind hole Fired perforated bricks of a kind of nonweight-bearing compacting or extrusion molding band tapered blind hole structure.Its blind hole is simple, and hole ratio is big, is applicable to compression moulding technology and extruding-out process, adopts the tapered blind hole structure to help saving construction material.

The utility model is design like this: it is made up of parallel right angle hexahedral profile brick body and containing hole wherein, the hole blind hole can be arranged on an end face, also can be arranged on two end faces, its blind hole is tapered blind hole or taper half-blindness hole, wherein hole diameter is greater than the diameter in taper half-blindness hole, the cone angle of slope in tapered blind hole or taper half-blindness hole is between the 1-80 degree, and hole count is more than one.

Below in conjunction with accompanying drawing an embodiment of the present utility model is specified:

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is the part hole generalized section of Fig. 1;

Among the figure: 1-brick body, 2-hole, 3-tapered blind hole, 4-taper half-blindness hole, φ A-hole diameter, φ B-taper half-blindness bore dia, α-cone angle of slope.

Brick body (1) is of a size of: 1,240mm * 115mm * 90mm

2、180mm×115mm×90mm

3、190mm×190mm×90mm

Hole (2) number is: 11.

The utility model has the following advantages:

1, blind hole is arranged on an end face or two end faces 0≤φ B＜φ A in the hole (2). Construction method is identical with the shop slurry construction method of solid brick.

2, the setting of hole (2) neither is subjected to the restriction of " little and many " of existing hollow brick, also is not subjected to the constraint of " aperture is big, hole count is few " of blind hole load bearing hollow brick. The aperture is changeable, and hole count is the amount doesn't matter, is applicable to the different various raw material of the plasticity index various porous bricks different with hole ratio.

3, blind hole is designed to the tapered blind hole structure of stress performance excellence, compares with common blind hole, be difficult for dry, burn till, transport, load and unload, cause artificial holes in the process such as construction.Under the same terms of holes not, hole ratio of the present utility model is big.

4, for making blind hole, the utility model both can adopt the pressing moulding, also can adopt the extrusion molding moulding, was not subjected to the influence of production technology.

5, raw material wide material sources both can adopt half-dried raw material, also can adopt the wet raw material of moulding.

6, hole ratio of the present utility model is greatly greater than bearing hollow brick with blind holes, and unit weight reduces significantly, is suitable for the urban skyscraper, helps reducing cost, and reduces cost.
