Abstract

The utility model relates to a laid dry hollow brick without need of mortar during construction. The brick is provided with a trapezoid groove at upper part and a trapezoid heave at lower part, which shall match completely. The both sides of the upper grooves are respectively provided with two trapezoid notches in the same size, four in total; and two trapezoid heaves of the same size are positioned at the both sides of the lower one, and four in total either. In this case, the brick can match each other completely. During construction, the brick and brick occlude with each other so that it is no need to setting out for measuring whether they are built straightly. After completion of building, grout concrete into the hollow part to finish construction. Comparing with adopting common sintered clay solid brick, hollow brick and non-sintered (machine-made) solid brick and hollow brick, this brick can shorten construction period and deduct man-hour cost.

Description

The laid dry hollow brick

Affiliated technical field:

The utility model is a kind of laid dry hollow brick for building, builds a wall with it and can shorten construction period, reduces work time cost.

Background technology:

At present: the solid brick that building aspect brick major part commonly used is fired for clay, the hollow brick that the part clay fires and the solid brick and the hollow brick of non-firing (mechanism) are also arranged, above-mentioned several brick must can be constructed with mortar, need unwrapping wire in the work progress, be used for comparing and whether be built into straight line, so long construction period, working hour expense is also higher relatively.

Summary of the invention:

In order to overcome that above-mentioned these several bricks use operations such as mortar, unwrapping wire in work progress and the long construction period that causes, the shortcoming that work time cost is high.The utility model provides a kind of laid dry hollow brick, and it can laid dry, without unwrapping wire, compares with other brick, can reduce construction sequence, shortens construction period, reduces working hour expense.

The technical scheme that its technical problem that solves the utility model adopts: this brick have two square hollow, on this brick top a trapezoidal groove is arranged, a trapezoidal projection has been sent out in the bottom, two parts just in time coincide up and down.The trapezoidal groove on top, every side have two trapezoidal recesses, and both sides have four trapezoidal recesses, its recess equal and opposite in direction.The every side in trapezoidal protruding both sides has two trapezoidal projectioies in the lower part, and both sides have four identical trapezoidal projectioies.This brick is just in time coincide when in any case interlocking block.After wall puzzles, finish construction to its hollow position placing of concrete.

The beneficial effects of the utility model are: in the process of building a wall, do not use mortar, and without unwrapping wire, so short construction period, save working hour expense.

Description of drawings: the utility model is further specified below in conjunction with accompanying drawing:

Among the figure: 1, trapezoidal recess; 2, hollow; 3, trapezoidal groove; 4, trapezoidal projection; 5, the trapezoidal projection in side.

The specific embodiment: in the drawings, there is the equal trapezoidal recess (1) of a trapezoidal groove (3) and side four on the top of this brick, and there is the trapezoidal projection (5) of four identical sizes of a trapezoidal projection (4) and side this brick lower part.This brick hollow position (2).When brick when building, trapezoidal groove (3) coincide with trapezoidal projection (4); Four the trapezoidal recesses in side (1) coincide with four trapezoidal projectioies (5) of side.When needing in any case staggered the block, trapezoidal groove (3) coincide with the trapezoidal projection in side (5), and trapezoidal recess (1) coincide with trapezoidal projection (4).

In practical operation, this utility model is built a wall under without mortar, situation without unwrapping wire, can shorten construction period, reduces work time cost simultaneously.

Claims

1, a kind of laid dry hollow brick, it have two square hollow, it is characterized in that: a trapezoidal groove is arranged on the top of this brick, and there is a trapezoidal projection lower part, two parts just in time coincide up and down.

2, laid dry hollow brick according to claim 1 is characterized in that: in the reproduction both sides of top trapezoidal groove, every side has two trapezoidal recesses of equal and opposite in direction, the trapezoidal protruding both sides in the lower part, every side has two trapezoidal projectioies of equal and opposite in direction, and four trapezoidal recesses on top and four trapezoidal projectioies of bottom are just in time coincide.The trapezoidal groove size and the trapezoidal projection of lower side on top are just in time coincide, and the size of the size of the trapezoidal recess of both sides, top and the trapezoidal projection of lower part is just in time coincide.
