Special-shaped ceilings, curved ceilings and what we often call special ceilings are also often encountered in design, compared with flat-topped ceilings, special ceilings will be more complex in construction and design, but they will also be more effective. Today, I will talk to you about how to design special ceilings, which mainly solve the following problems:
1. What do we often refer to as special smallpox?
2. How to understand linear special smallpox?
3. What is the structural analysis of the planks in the sky?
01. What is Special Smallpox?
Our definition of special ceiling refers to the non-single straight line composition of the plane ceiling or the plane drop ceiling, which can be understood as a special ceiling.
Special ceilings are mainly divided into two categories: linear special ceilings (e.g., pitched roofs, rhombic roofs, false beam roofs) and curved special ceilings (e.g., domes, special-shaped roofs).
1. Linear special ceiling
2. Special ceiling with curved surface
Curved surface special ceilings can be divided into single surface ceilings and three-dimensional surface ceilings.
a. Single-curved ceiling
As shown in the diagram above, a single-curved ceiling refers to a special-shaped ceiling with only a single plane curved in the indoor ceiling.
b. Three-dimensional curved ceiling
As shown in the diagram, the three-dimensional curved ceiling refers to the special-shaped ceiling with two or more curved planes in the indoor ceiling. Such as: domes.
02. Analysis of special ceiling process practices
The picture above shows a typical example of a linear special ceiling, and we can see that this type of ceiling is often referred to as a "pitched roof".
1. The practice of pitched roofs
When using a pitched roof as a suspended ceiling, beams, ridges, straw mat surfaces and corrugated corrugated roofs are usually added to the pitched roof to create a spatial atmosphere of a wooden building, which is particularly popular in oriental-style buildings and interiors.
Let me show you some design cases, all of which use this design technique, you feel it~
2. Case analysis
Next, let's take an example of a pitched roof and see how it is done on site.
△ Design renderings
a. Drawings and node analysis
This kind of sloping roof must pay attention to the relationship between the ceiling plan and the node diagram, and combine the construction photos of the site on the basis of understanding to have an in-depth understanding, so as to truly grasp the practice of the suspended ceiling, and then everyone will face the inclined roof, it will become extremely easy.
△ Ceiling plan
b. On-site construction
3. Precautions for the construction of inclined roofs
a. When this method is adopted, the length of the low-end boom of the inclined roof is easily > 1500mm, so when giving the bottom, it is necessary to check whether the conversion layer needs to be set.
b. Pay attention to whether there is large-scale mechanical and electrical equipment in the ceiling, whether it is necessary to reserve the maintenance port, if it is necessary to reserve the maintenance port, it is necessary to consider whether the scheme design is fighting with the maintenance port.
c. In order to ensure the safety and stability of this inclined ceiling, we must pay attention to the positive and negative buckle settings of the main keel, the main hanger and the secondary dragon pendant when giving the bottom.
d. If the owner has particularly high requirements for fire prevention and acceptance audit, you can use glass magnesium board instead of flame retardant board to make ceiling base board, but no matter how the "meat" part changes, the "skeleton" will not change.
△ Flame retardant board acts as a keel, which can be replaced by glass magnesium board
e. There will be certain differences in the practices adopted by different requirements and different scales, but after understanding the above construction practices, almost most of the inclined roof structures can be used.
03. Analysis of the process of the wooden board
Like the oblique ceiling case mentioned above, if you want the wood grain effect, you can use the wood grain transfer aluminum plate to make a false beam to achieve it. Next, I would like to introduce you to 3 ways to go to the sky with a plank.
1. False beam ceiling practice
△ False beam ceiling node diagram
2. False beam ceiling form
△ Schematic diagram of the form node of the false beam ceiling
3. Solid wood board ceiling practice
△ Solid wood board ceiling node
Through comparison, we can see that in addition to the wood grain transfer aluminum plate to make false beams, the practice of using wood to make false beams is almost the same, but at present, in China, the fire protection requirements are becoming more and more stringent, if it is a commercial business place, it is recommended that we try to use the form of wood grain transfer aluminum plate to do the decoration of false beams.
