The clay bricklaying process of an arch kiln#shorts

The clay bricklaying process of the arched kiln is a delicate and technically demanding process, mainly used in the construction of traditional kilns. The arched structure is supported by the deadweight of the masonry and the compression force of the arch.

1. Preparation

Choose the right clay: Choose the appropriate type of clay according to the temperature requirements of the kiln. Commonly used is refractory clay, which has high heat resistance and crack resistance.

Material preparation: The clay should be soaked in advance and properly treated. Usually the clay is mixed with water until it reaches a plasticity suitable for bricks. Make sure the bricks are uniform in size and have no cracks.

Tool preparation: Including hammer, shovel, trowel, rubber hammer, level, brick cutting tool, brick hammer, etc.

2. Foundation construction

Foundation preparation: First, you need to build a solid foundation on the ground. The quality of the foundation directly affects the stability of the kiln. Usually a layer of refractory material is laid on the foundation to ensure that heat is not absorbed by the foundation.

Bricklaying: Plan the placement and arrangement of each layer of bricks according to the size and shape of the kiln to ensure the stability of the arch structure.

3. Build the bottom of the arch

Bricklaying: Start with the bottom of the kiln. The bottom bricks need to be laid flat and level. You can use "dry masonry" or "wet masonry", that is, no or a small amount of mud as a binder.

Symmetrical layout: Arrange the bottom bricks symmetrically from the middle, and each layer of bricks needs to be measured horizontally to ensure the stability of the kiln structure.

4. Build the arch structure

Gradually lift the arch: When building the arch, the bricks should be lifted layer by layer. Use wedge-shaped bricks (or inclined bricks) to build the vault structure. Each brick must be placed very accurately to ensure that the pressure between the bricks is evenly distributed.

Use temporary supports: During the masonry process, support frames or templates need to be set up to help support the weight of the arch bricks and prevent the arch from collapsing. The supports are generally wood or iron frames.

Brick jointing: Each brick should be tightly connected to avoid gaps. The angle of the bricks can be adjusted to ensure a tight fit and reduce heat loss.

5. Complete the top of the arch

Brickwork of the arch: The bricks of the arch are usually gradually reduced to fit the narrow space above. The final brickwork will present a dome or arc structure. The overlap of the top bricks needs to be precise because it is the supporting core of the entire kiln.
