Master class from the pros: a complex truss system hipped roof with his hands

From the project to build the roof, life hacking, tips wizard

It is no secret that the more complex the design, the more demanding it is to skill the performers, and the more expensive. And this applies to both the houses of architecture as a whole and individual areas, such as roofs. But the visual component in complex shapes much higher. What they are attractive to many developers, who can afford such delights. One of the members of our portal, professionally engaged roofs, shares the secrets of his skill on the example of the construction of complicated tent structure.

Why and when you need a project

Ideally, any construction should start with the roof project. Plans needed for the construction of a complex truss construction. Simple roofs for small homes can be done on site. Another important point: the need to master the drawing, which is able to read it. If the artists chose the Uzbeks, the usual photos of the roof would be sufficient.

Roof, about which will be discussed, just can not be called simple.

A drawings Termit.spb (Andrew) is able to not only read, but also to create. According to him, the model of the roof with rafters traced - is needed. It allows you to understand the desires of the customer and agree on the future appearance of the roof.

For the convenience of the work will need scaffolding, such.

Step racks attached to a section of the deck boards themselves stand of timber 50 × 100 mm, they are the same then they will go to the cut and will cranial bars. A dyuymovka with deck will start up on the rough floors in hardwood floors - at once and save on material and not have to think where to put more wood waste after use.

The wizard also fulfilled roof drawings.

Customized rafters by eye I'm not really a master, so this roof will be cut according to the drawings. Here we see the attic floor joists, layout plan mauerlatov Scheme nakosnyh trusses, roofing plan with the mapping projection sizes (for pitched sizes must be divided by the cosine of the angle of the roof), and one of the sections of the roof, all of them will be five or six. The main thing is to draw them correctly.

Sectional view of the roof.

How do carpentry goats

During the manufacturing process of elements of roof Andrei system uses special carpentry goats, collecting them from the same timber as the rafters themselves. The main condition - the strength, because through this "machine" will be more than one cube timber.

Dimensions:

• Working length - no more than 2 meters.
• The length of the legs - not more than a meter.
• Height - 0.7 m (depending on carpenter growth, this height is optimal for the growth of about 2 meters).

It is imperative parallelism of goats, and the horizontal - all vymeryat the level of the installation. Time spent painstaking installation work simplification pay off the chain saw and cut quality. Naturally, the guarantee quality processing circuit is acute. It was a chain saw is indispensable for the processing section 100 mm rafters.

As it will be.

Marking and sawing rafters

To mark the rafters Andrew uses a "big Malki two lines of" if the plans only its roof (house, farm building), to make such a device can be of conventional plywood. If we engage in roofing work professionally, it is better to use solid wood: beech, oak, hornbeam, and mahogany. For convenience, at the edges of the rafters, at the end of the bevel made a small keel for fixing the line on the workpiece.

Dimensions Malki:

• Length - 800 mm.
• Width - 50 mm.
• First strap - 400 mm.
• The second strap - 300 mm.

Complementing the marker set of small bevel, for nakosnyh rafters, and completes the regular polygon with a tape measure.

Those who do not have extensive experience vrubok marking the first stage of development of this science would recommend to carry out the markup tools by sliding back and forth. In this case, can not be done "mirror" markup vrubok angle. Performing layout details vrubok have to work with a material that strongly walks in height. It vrubka and to compensate for the height difference. Bevel always slides on top of the rafters, elevation always put from the upper edge rafters. This is - the key to success and a flat plane rays.

Oblique cut rafter hipped slope of the fifties comfortable doing parketkoy (hand saws wood) Long reach - 75 mm.

In order not to get carried away and do not cut the party sided trusses, Andrew advises beginners to mark and cut the workpiece in pairs: right-left did the figure mentioned was postponed.

Supporting notching for naslonnyh rafters: two oblique cutting parketkoy, sample residue sharp chisel. Notching a thick bar (100 mm) at the cost of more convenient to do saw.

When working alone heavier - helps savvy. For manipulation with the items that are a little shorter than the goats, convenient additional support.

For a very short workpieces can be used backer board and clamp.

About cabins, storage of materials and physics

Termit.spb

... A few words about the cabins: if you decide that you need a change house, and you will be for some time to live (time of year does not matter) in it, never buy ready! In the summer in these houses will be hot, even with a split, and in the winter (as I), in the autumn, just wake okolevat. You want to live comfortably and based - do shed independently, with warming, a thickness of not less than 100 mm, with films and sizing seams. Remember, the warm air will find where to go.

Timber is a natural humidity, imported in advance, if stored properly dry out, which affects the work and the result. Instead of "small pile" - a space from the ground and through the storage timber linings, ventilation and drying. Regarding the blackening, it is not so critical, in adverse conditions, namely, under a well ventilated roof, the fungus will stop development.

To save on a crane or a worker, Andrew suggests using a hoist (electric winch). And if there is no electricity at the facility - rise blocks simplify cargo. One unit reduces the weight of the load in half, two blocks - four times. If apply physics knowledge really ease the physical labor.

roof assembly

Although the overlap would have to mount a bricklayer, and the mission was borne by the roofer as technical supervision and worker from neighboring countries as performers. The large span girder section 100 × 200 mm, main run - 100 × 200 mm; Laying nets for fixing on corners. The ends of the shut-board 50 × 200 mm, on nails in combination with screws, all hardware galvanized.

After several alterations and explanations from the worker to the "mighty Russian", which is usually in the air "zapikivayut" mauerlat liberated almost perfectly.

Mauerlat tower of the double height, when assembling the rafters maximum attention to landing vrubok to fit maximized. Even a slight displacement of the notching in the side streets is fraught with the need to align the entire plane. Another key point - the peak of the tower assembly, as all 16 members should take place strictly on. The second time, and with the help of clamps and parts of all happened.

This topic is considered the classic look hipped roofs, the inclination angle rays less than 30 degrees, the wind load is minimized. Rafters have a bearing on the central pillar and notching bearing on mauerlat. Nakosnye have additional support. In the future, will be filed cornices, which further increase the reliability of the roof.
