Adopting Roof Model House Joglo
Wednesday, April 14th, 2010 by admin # Homedesign
Build joglo roof, which is now popular again, should not be indiscriminate. In addition to the philosophical values contained, one can put the pole fatal in its construction.
According to the book Heinz Frick Building Construction Science vol II, the meaning and functions of the roof construction is as protective of human towards weather, better protection against heat and rain. Rainfall in Indonesia is quite large, so that rain water falling on the roof surface must be quickly distributed into the soil. That requires the slope of the roof area large enough, ie 30o. With this, hopefully, the rain water can be discharged directly from the horizontal surface of the roof through the gutter. Gutters are attached along the lip of the roof surface.
This is one reason why traditional roof forms in Indonesia has a fairly steep slope. This can be evidenced by various forms of sago palm-coated roof or a shingle from west to east Indonesia. Traditional roof forms that have an average slope of about 30o. An example is the roof of the house joglo in Java, West Sumatra gadang homes, traditional houses Betawi, until half-circle-roofed houses in the interior of Papua Dani. Now many found homes gadang or tin-roofed houses tile-roofed Betawi. Although the cover surface of the zinc roofs, which slope is more flexible, but still traditional roof is still steep.
Concept Joglo
One form of traditional Indonesian roof of the building is joglo. Joglo roofed building is very much its kind, which are distinguished based on the existing building functions below. In essence, the form of a roofed building has a characteristic shape joglo distinctive roof structure.
Construction of traditional houses that still thick joglo tradition, based on the philosophy joglo, must use teak. This teak wood must also comply with certain characteristics are determined by location and function of mast-mast. For example, teak wood comes from trees with branches two or three branches are used for the column or pole, or a particular pillar. According to belief, the use of timber in accordance with the requirements will be able to bring positive things for the future occupants.
Whatever shape the tree, there is an understanding that the structure must be understood, ie pole or pillar of the roof load will be distributed to other structural element to come into the land. For these reasons must be sturdy pillar. Just imagine, major foundation must distribute the load of the roof frame, such as roof tiles, rafter or usuk, and gording.
Pole Type (Soko)
Each pole has a name based on its location in the building. One or more columns that support the roof of the most high-called pillar, the pillar that is located over the outside of the pillar is the cornerstone Rowo, while the poles that support the roof of the outermost called the cornerstone patio.
In addition, there are several types of poles used for other joglo roofed building, which is the cornerstone bentung, which is hung between the roof top to roof beneath. Meanwhile, the cornerstone Santen is a pillar that does not directly support the roof, but the length of the girder support at a large building roofed joglo.
Roof Construction Joglo
Joglo roof truss construction consists of several columns called the cornerstone. Joglo roof construction has the absolute pillars known as the cornerstone. Without the cornerstone, the roof of the house can not be called joglo roof. When applied to pure joglo roof construction in residences, the cornerstone that serves as a proponent of the roof with a fairly steep slope of the roof should not be omitted.
Each type of these pillars supporting the roof which has a different slope. Increasingly toward the exit, the slope of the roof will be more gentle. Although the slope, but the slope of the roof must be able to channel water from the surface of the roof with a good field. In addition, must be taken into consideration in determining the slope of the roof, that roof with tile roof coverings that are too flat will cause leaks.
Shaped roof joglo many uses of wood materials, ranging from plain wood to wood-filled ornaments. This resulted in expenses that must be channeled to get to the ground by each pillar quite heavy. Actual load is carried by the pillar can be calculated, that is by knowing the roof area supported by each pillar. The area is then multiplied by the weight per square meter roof, so that got the roof load to be borne by each pillar or pole. As a result, the total load must be distributed by a major foundation is smaller than the voltage of land per square centimeter. When the load is distributed by a major foundation is greater than the ground voltage, then the foundation will be dented.
Applying Model Joglo
Now this concept of building a roof joglo difficult to apply, because the wood is required to have certain requirements and the way development takes patience too high. Meanwhile, a few poles required joglo roof construction, can not be eliminated because it has a value philosophy and specific functions.
Requires the presence of Filofosi joglo roof pillar as a room divider columns. Dividing the space becomes less flexible, because of the pillars or the roof pillar as the dealer charges. When you still want to use the philosophy joglo roof construction, space and its spatial distribution must follow the location of the cornerstone.
Difficulties arise if the area of the space created by the pillar is smaller than the needs of residents. How to expand the space divider for example by backing up several feet of space. However, what happened? Soko will be in the middle of space. In fact, uncomfortable if these poles are in the midst of space.
In addition, because of limited land, homes today typically have smaller dimensions than the house antiquity. Placing the pole or pillar in the middle of a small room that clearly was not wise.
In order to implement the desire joglo roof construction can still be executed, then the only valid when using joglo roof model but uses a pyramid roof construction. This is one alternative to the division of space is still flexible and suitable to the needs of residents, but still can use the roof joglo model.
