Description

[Detailed Description of the Invention] The present invention relates to the roofs of balconies, terraces, entrances, etc. of houses, and in particular, the rafters that receive the ends of the rafters of the roof support frame so that the installation slope of the roof can be adjusted within a specific range. In addition to making the hanging surface two planes with a gentle and steep slope, the side frame of the roof plate support frame can be fixed by preventing exposure of the rafter hanging end surface that occurs as the roof slope increases. .

Conventionally, the slope of a roof installed on the outside wall of a house as described above is specified by the fixed position of the front and rear ends of the rafters of the roof plate support frame, and the front end of the eaves side is determined by the height of the pillar or beam supported by the pillar and the outside wall of the house. It is determined by the positional relationship of the height of the rafter hooks fixedly installed in the roof, and in this case, the rafter receiving surface of the rafter hooks is an inclined surface that matches the roof slope, so it cannot respond to changes in the roof slope. Therefore, if the roof slope is different, rafters must be prepared to accommodate the different slopes.
Moreover, while the roof slope is around 10° in warm regions, in cold and snowy regions it is desired to have a steeper slope of 15° or more. However, it was clear that this was disadvantageous in terms of production, economy, and construction work, and improvements were desired.

The present invention is in response to the above-mentioned request, and the receiving surface of the rafter hook is made into a two-slope plane of slow and steep slope, and the rafter is fixed to the rafter hook with screws at the ridge line part formed by the two planes, and the end surfaces of both sides of the rafter hook are covered. Then, fix the mounting piece, drill an arcuate long hole in the mounting piece that matches the steepness range of the rafters, and insert the bolts protruding from the side frames provided on both sides of the roof board base frame into the arcuate long hole. The roof is secured by tightening nuts to secure the side frame and provide stable installation of the roof.

Hereinafter, an embodiment of the present invention will be described for the case of a balcony roof shown in the drawings.

FIG. 1 is a partially omitted perspective view of the proposed roof installed on the exterior wall W of the house, and FIG. 2 is a perspective view showing the main parts of the frame member with the roof plate omitted,
Figure 3 is an enlarged perspective view of the main parts showing the relationship between rafters, rafters, and side edges; Figure 4 is a partially cutaway side sectional view of the side edge of the roof when a gently sloped roof is installed; FIG. 5 is a partially cutaway side sectional view of the main part in the case of a steeply sloped roof.

In the drawing, 1 is a rafter hanger fixed to the house wall W with hooks 8 and screws 9; 2 is a rafter;
3 is a main building, 4 is a front frame, and 5 is a side frame, which are connected by bolts, screws, etc. to form a support structure for the roof board 7, and the eaves side of the rafter 2 is supported by a support 6.
The other end of the rafter 2 is fixed to the rafter hook 1 with screws. The roof plate 7 is fixed to the main building 3 with screws, and its front and rear edges are fitted into the respective fitting parts of the upper part of the rafter hook 1 and the upper part of the front frame 4 to form a roof, and the roof slope is as follows. It is determined by the slope of the rafter 2 supported by the receiving edge 11 of the rafter hanging 1 and the support 6, but in the case of a conventional rafter hanging in which the receiving surface slope of the upper surface of the receiving edge 11 is adapted to the predetermined roof slope, the roof If the slope is large, even if the rafter 2 is fastened to the rafter 2 from the lower surface of the receiving edge 11 with screws, the fixation becomes extremely unstable and sufficient fixing strength cannot be obtained. The surfaces are divided into a gentle slope receiving surface 16 and a steep slope receiving surface 17 corresponding to the gradual and steep slope of the roof.
By fixing the lower surface of the receiving edge 11 to the rafter 2 with screws 18 on the ridgeline E formed by the two planes, the gradual slope can be adjusted. Stable and reliable fixation can be achieved at all times within this range.

Further, the side frames 5 of the support frame of the roof plate 7 cover both end faces of the rafter hook 1 when the slope is the gentlest, and the edges thereof approximately contact the house wall surface W, and as the roof slope increases, The edge is separated from the wall surface W of the house, and the end surface of the rafter hanging 1 is exposed, creating a gap that not only allows wind and rain to leak in and spoils the appearance, but also makes the holding and fixing of the side frame 5 unstable. However, in the present invention, this point is fixed by fixing the mounting pieces 10 covering both side end faces of the rafter hanging 1 with screws, welding, etc.
An arcuate long hole 20 suitable for the slope range of the rafter 2 is bored in the mounting piece 10, and a bolt 21 protruding from the side frame 5 is inserted into the arcuate hole 20 and tightened with a nut. The side frame 5 is stably oscillated and fixed in response to fluctuations, and the rafter hook 1 is
This prevents the exposure of the end surface of the wood and solves the above-mentioned drawbacks of the conventional method.

In addition, from the above conditions, the interval between the ridges 12 and 13 that form the upper roof plate insertion edge of the rafter hanging 1 should be wide enough to not hinder the tilting of the roof plate 7, and the space provided on the side frame 7 should be The edges of the roof retaining edge 25, the purlin receiving edge 26, and the lower flange 27 on the rafter hook 1 side are attached to the edge 1 of the rafter hook 1 so as not to interfere with roof slope change adjustment.
3. It is necessary that the shape is such that a gap is provided to prevent contact between the receiving edge 11 and the mounting piece 10.

Fig. 5 shows the relative positions of the rafters 1, rafters 2, side edges 5, and roof 7 in the case of the steepest slope.
The protruding bolt 21 provided on the side frame 5 is attached to the mounting piece 10
The lower surface of the rafter 2 faces the steeply sloped receiving surface 16, and is shown fixed with the screw 18 at the ridgeline E position of the receiving edge 11 of the rafter hook 1. ing.

As explained above, according to the present invention, rafter hangings can be installed by adjusting the slope of the roof according to certain design conditions. There is no exposure, and the side frames can be securely fixed, and the effect of improving the practicality as a roof for a balcony or the like is extremely large.
