Manufacture of flat roofs and roof trusses for residential buildings

A flat roof is typically a lower roof and is defined as a roof slope of ten degrees or less from the horizontal. Usually the pitch angle is governed by the type of finish applied to the roof. Top views of Jamaican homes for sale.

The functions of a flat roof are:

a) Prevent the entry of rain and dust especially at joints and junctions

b) Resist the effects of wind (both pressure and suction), sunlight and solar intensity

c) Meet the requirements of current building regulations regarding structural stability, fire safety concerns, thermal insulation, condensation, vapor insulation and loads, dead and applied, depending on whether roofs are allowed.

d) Provide a suitable bearing surface

e) Allow for movement due to stress and natural causes

Construction of a flat roof in wood

Thirty-eight millimeters to fifty millimeters of wood beams are used in the construction of wooden flat roofs and seventy-five to two hundred millimeters deep are placed on the edge between the ends of four hundred millimeters to six hundredths of developed beams. on or against block walls and partitions. The depth of the beams should be sufficient to enable the lower rooms without collapsing, while the width is usually fifty millimeters, which will provide enough space to accommodate the boarding.

It should be noted that the strength of wooden beams is not in their width, but in their depth, therefore increasing the strength requires increasing the depth.

Flat roofs must be provided with springs to drain rainwater as quickly as possible. The direction of collapse must be determined by the position of the roof in relation to other buildings or its size or shape.

To stop the fall, the pellet pieces are attached to the top of the rafters and where the ceiling boards are nailed.

Firing strips consist of either thin lengths of wood nailed

To the top of each joist or lengths of wood of varying depths nailed to the joists. Peak firing is used to create different depths for roofs covered with agglomerates and planks laid parallel to roof slopes so that variations in plank level do not impede water-rain flow along shallow timber supplies.

Flat roof on concrete

Flat concrete roofs are constructed in the same way as reinforced concrete floors – both in situ and prefabricated.

Roof rails

Trusses are frames that are structurally designed based on the principles of triangulation. It usually consists of top and bottom wires, tension and compression webs and devices used to connect the members.

The trusses are designed to carry the load on the roof and transfer it to the nearby wall where it rests. The triangulation of the trusses varies according to the span It is important that the roof trusses are firmly attached, as lighter sections are often used.

Advantages of Roof Railways

1. Roof trusses save material and labor costs on site.

2. Roof trusses can also eliminate internal load-bearing partitions because the trusses are self-supporting.

3. The trusses can be installed quickly and therefore the structure can be built in a short period of time.

4. Root trusses come in many forms to solve almost any problem.

5. Trusses are usually designed to extend from one exterior wall to another with a length of six to nine meters or more.
