Brick making tools

Following is essential masonry equipment for laying brick , along with the purposes of each tool. It is the fundamental tool for brick masons, available in different sizes for certain tasks pertaining to mortar application. The corner pole is used as vertical support for the line block, which has a twine that designates the appropriate placement for each brick in a course. The corner pole may be clamped to frames, or pinned between blocks to keep it upright and in position. The line block is a wooden device that stores a line twine , which is able to catch on the edges of the structure.

Two are used at the ends of a line, with twine wrapping around them, and they are attached to the edges of walls or to corner posts, and their line is wound tight and stretched horizontally, marking the top corners of the bricks that are to be laid in a given course. Levels of various sizes are used for certain masonry activities. Four-foot levels are used to make sure that courses are flush and even, or to stand corner poles vertically. Two-foot levels can be used to perfect a few freshly laid brick, and torpedo levels are used to make sure an individual brick is a level and flush with those adjacent to it at its ends.

Wall ties are items that are placed in block or brick walls that are meant to connect to outer walls built in front of them, to keep the outer walls even and stable. When the block or first brick is laid, wall ties are placed in the bed joints every few courses, and then they are extended forward, into the mortar joints of the outer wall built in front of the original. Forming machine frame: it adopts high-strength steel and special welding technology, which enables the sand brick making machine to hold the compact pressure and the elements of brick block making machine reliably.

Control system: it adopts computer control system and the design of man-machine interface, and the electrical apparatuses adopt the international brand. The brick and block making machine can realize continuous productions. Distributor: it adopts the sensor and the hydraulic proportional drive technology, and the hydraulic cylinder drives the distribution box to flick. The flickering distribution box drives the distribution teeth to rotate for degrees with high speed, so that the brick block machine distributes the materials compulsorily and evenly.

Meanwhile, the mold vibrates with low frequency, and the mold cavities are full of materials due to the continuous vibration.

Storage and feeding device: it is controlled by the computer. When feeding the materials, the device can avoid the influence from the external factors. And it contributes to the even distribution. Through several decades of development, Aimix has developed as a top enterprise.

Such bricks should be, of course, properly dried before doing so. If after burning and subsequent cooling, the bricks retain the uniform shape and develop the brick red color and have a good appearance, the earth is said to have passed this test also for the manufacturing bricks process.

Then, the soil composition is defective with respect to one or another of the essential ingredients. The soil may not be suitable for manufacturing of bricks of good quality without proper investigations and treatment. These tests are carried out on a series of test bricks made from the soil as above and which has already passed all the three tests. These tests can be carried out approximately in the field, or, even in the laboratories. The test involves dropping the bricks, one by one, from a height of meters on a hard dry ground below.

For the laboratory testing, the test specimens are subjected to routine testing in a well-equipped civil engineering laboratory for compressive strength, bending strength and water absorption.

A series of steps are necessary before the earth is ready for moulding of bricks. The area selected for the brick-earth is first cleaned or unsoiled at the top. This is necessary to remove most of the undesirable top soil which is always rich in pebbles and organic matters. From this cleared area brick-earth is obtained by:.

This method is applied to large-scale mechanized brick making and especially when the earth is hard and compacted. After the removal of soil, the clay is spread in heaps and layers over the ground for weathering or seasoning. During this period, it is also cleared of any pebbles, stones and lime nodules.

Moreover, any clay lumps are broken into a fine powder so that a uniform-sized seasoned earth is prepared. The seasoned clay is said to be ready for conversion to mud by mixing with appropriate quantities of clean water. These Operations of selecting the earth, clearing and digging it, spreading it for weathering are together called as winning of clays. Tempering means converting of the prepared brick earth into a homogeneous mix of the desired plasticity by mixing it thoroughly with proper quantities of water.

This is done either by manual labor or with the help of a specially designed, mechanical device called pug mill. In manual tempering, the clay is thoroughly kneaded under feet of either men or cattle with gradual additions of water till desired homogeneity and plasticity are obtained. Molding is the process of making properly shaped brick units from a thoroughly tempered clay.

There are two main methods of molding. Machine Molding : When specially designed machines are used for moulding of bricks. In the advanced countries, however, mechanized brick making is the main process for large scale manufacture of bricks.

In hand moulding, the quality of the tempered clay is invariably soft, so that it can be molded into the required shapes conveniently. The mud contains more water percent by weight than what is used when machine molding is to be done.

Bricks are shaped from such a soft mud by hand either on a specially prepared ground called ground moulding or on special tables called table moulding. Tools: The essential tools used in the hand moulding process are: a brick mould, cutting wire or strike, wooden plates called pallets, and a stock board. The stock board also called molding block, is a small wooden block, slightly bigger in dimensions than the mold and with a raised central projection carrying the identification mark frog.

The strike made up of wood or metal has its one edge quite thin to slash surplus mud; cutting wire is meant for the same use. At present, this is the most common method of moulding of bricks in most countries. In this process a piece of land the ground is first cleaned, then thoroughly leveled and often made smooth by plastering.

The mold is either first dipped in water slop molding or some sand is sprinkled on its inside surfaces sand molding. This step is necessary to avoid sticking of the mud to the sides of the mold. Then, the mold is placed on the ground. A lump of mud is dashed into the mold by hand. Care is taken to see that mud reaches the edges and corners of the mold. Any surplus mud is then removed by using either the strike or the cutting wire.

After this, the mold is lifted up with a jerk. The molded brick is left behind on the ground. The moulder repeats this process. The face of the brick which rests on the ground will be naturally rough and without any identification mark. This requires a stock board and pallets, The stock board has a raised projection 6 mm carrying impressions or marks of the manufacturer carved out in it.

For moulding of bricks using the stock board, the mold is, as usual, either first dipped into a bucket of water slop molding or, some sand is sprinkled on its inner sides sand molding. This mold is then placed on the stock board with projection in the center and a lump of prepared clay is dashed into it. Any surplus mud is removed by using the strike or cutting wire.

A pallet is then placed on the top of the mold and the stock board is turned over. Another pallet is placed on the upper surface of the green brick and it is taken to the drying field, where it is placed first on its edges to dry. The pallets are thus available for use again and again. This process, where pallets and stock board are used is called rightly pallet molding. It is also a type of hand-molding method. The moulder carries out all the operations of pallet-molding on a table of suitable dimensions and while in a standing position.

Such a table is large enough to accommodate all the materials required in the hand moulding, namely: a stock board, molds, cutting-edge bucket full of water or sand and supply of tempered mud. The moulder places the stock board in front of him, sprinkles some sand on the inside of a mold or dips it into water, places it on the stock board,. A helper places another pallet on the brick so molded and carries it away to the drying ground where he makes the brick stand on edge. The pallets are thus available for use again.

Although initial cost is little higher in table moulding, it is considered more efficient. In advanced countries, machine moulding is an essential part of the Mechanized brick making plants.

It is both cheaper in the long run and gives bricks of uniformly good quality. There are two broad types of processes used in machine moulding: first, stiff mud process and second, dry press process.
