Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a purlin support material 4 with an eave protrusion 2 at one end and a joint 3 having the same length as the eave protrusion 2 at the other end, on the upper edge 1 of a truss base. A roof assembly consisting of a pair of trusses 6 installed in parallel at regular intervals, and a plurality of purlin materials 9 whose ends 7 are fixed to the joint portion 3 of the purlin support material 4 via joining fittings 8. The purpose of this is to improve the strength of the roof assembly and to significantly reduce the time and effort required for construction.

In addition, the reference numeral 10 in the figure indicates that the mounting bracket 11 of the truss 6 is a cutting;
5 shows the wall panel on the wife's side.

Since the present invention has the above-described configuration, in its construction, first, one end is attached to the upper edge 1 of the truss base at the eave protrusion 2.
A pair of trusses 6 are installed on both wall panels 5 on the gable side, and purlin support members 4 with the other end having a joint 3 having the same length as the eave protrusion 2 are attached in parallel at a certain interval. Mounting bracket 10
The joint parts 3 are fixed so as to face each other through the joints.

Next, after interposing a plurality of purlin materials 9 between the opposing joint portions 3 of the purlin support material 4, the both ends 7 of the purlin materials 9 are fixed to the joint portions 3 via the joining metal fittings 8. As shown in Figure 3, purlin supports are arranged at regular intervals on the upper edge of the truss base, with one end protruding from the eaves and the other end a joint having the same length as the eaves protrusion. A roof assembly is created on the wall structure by a pair of trusses attached to the wall structure and a purlin material whose both ends are fixed to the joint portion of the purlin support material via joining metal fittings.

In conventional roof assemblies of this type, both ends of the purlin material were directly bonded and fixed to the upper edge of the truss fixed on the gable wall panel, which caused the load to concentrate on the truss, resulting in a decrease in strength. It is not easy to do so, and the installation of the cantilever beam that is attached to the side of the truss to form the eaves has the disadvantage of requiring many parts and labor.However, as described above, the present invention Both ends of the purlin material were fixed to the joints of the purlin support material attached to the upper edge of the truss, so the load of the roof assembly was distributed between the purlin support material and the purlin material and fixed onto the wall panel. There is no need to concentrate on the truss, and since one end of the purlin support material forms a cantilever, there is no need to separately attach a cantilever for the eaves to the side of the truss.

Therefore, according to the present invention, the strength of the constructed roof assembly can be significantly improved, the labor and time required for construction can be greatly reduced, and the structure of the truss is simple, making it possible to manufacture it in a factory. Therefore, the cost required for construction is extremely low.
