Description

Field of the Invention

The present invention relates to joint free sandwich brick used for building block serving as a mold when carrying out civil engineering and construction works and forming an external appearance of a structure, a building structure and a method of bricking a wall using the same.

Background of the Invention

Generally, when carrying out a civil engineering and construction work, several stages of processes are performed. Thus, it is required to take a long term of works, waste additional materials and use heavy weight materials. Also a lot of professional human resources are supplied, thereto, causing a building cost to increase and leakage frequently occurs due to problems on the material and the construction. Furthermore several problems exist, such as pollution generated from the material, fire, cracks, efflorescence phenomena etc.

Particularly, a bearing wall and a non bearing wall of the building structure are fabricated by forming a wall space into a desired shape generally using a mold infusing mortar made of cement and coarse sand into the wall space in a state that a reinforcing bar is placed and curing the motor. Alternately the bearing wall and the non bearing wall are fabricated by bricking cement blocks or cement bricks made of cement and coarse sand or bricking another kind of bricks. And an exterior wall of the bearing wall of the bearing wall is plastered with the cement mortar or finished by facing a tile or by bricking clay bricks.

However when forming a cement motor wall according to the related art method, efflorescence occurs, that is the cement mortar is partially, dissolved and outwardly flows due to an introduction of rainwater, causing the exterior wall of a building to be stained and in order to remove the efflorescence the exterior wall should be recoated with paint. Also the related art bearing and non bearing walls are weakened in intensity and have cracks due to a load of the building as time elapses. In addition, it is required to spend much time on bricking bricks or blocks and plastering, much money and profession human skill is also required. This involves very much time and cost on repairing process for leakage, cracks, efflorescence or the like.

To overcome the above stated limitation, in the present invention novel joint free sandwich brick is invented.

Object of the Invention

In the present invention joint fee sandwich brick is very easy to use as a building block serving as a mold when carrying out engineering and construction works and forming an external appearance of s structure.

The present invented block structure capable of firmly placing a reinforcing bar therein in length and width directions and building structure which can be easily built by any person without a professional worker in reduced term of works.

In the present invention multiple holes are provided directly into the bricks so, electric water, water, cable or telephone connection pipes/cables can easily done after the construction work is completed without affecting the existing construction.

The main objects of the present invention are as follows, All sides of bricks are made with prefect angle and perfect size so work will be easy and fast.

It is not required any skilled person to use the present invented brick.

After wall construction no curing is required.

In the present invention no groove filing required as work is joint free and no plastering for wall inside and outside required. To tiles fitting is required.

Single labor is required to use the present invention

Saving of time and labor to use the present invention

It requires minimum time for surface leveling so, paint will bind well and lasts long.

As outside glaze ( water proof) tiles will not allow moisture rainwater slippage and this will protect inside healthy environment.

As tiles are cured at high temperature and pressure it will have more strength and none fading of colour.

No cracking in wall surface which ensures bacteria and moisture proof.

The bricks are prepared without firing so, it is eco friendly and power saving.

Different types of elevation designs creation is possible to increase aesthetic value of building.

This bricks get insulation property so building heating /colling will be reduce. Building Outside is of glossy so heat reflection will also reduce building heating.

Less electricity will be required for building life will be increased.

- Durability and strength of the bricks are higher then the normal bricks so these bricks last in good condition over the life span of building.

High degree of resistance to fire is major asset for this bricks which makes a safety aspect. This bricks do not emit any toxic fumes and does not degenerate with time.

These bricks are acid, detergent and scratch resistance.

These bricks are light weight compared to normal and concrete bricks so, building does not required heavy foundations, structure frames and slabs, which reduce the construction cost of the building.

Statement of the Invention

In the present invention lower and upper side surface of the bricks are provided continuous grooves to join the two bricks in incline position or in overlapping position. In the present invention multiple holes are provided into each bricks to transmit the water connection, electricity line, cable line, telephone line etc, by just inserting pipes.
