Instead, the screw shaft 61 is passed through the building wall 6 in advance and the tightening plate 7 is attached to its tip, and then the engagement grooves 81 and 82 of the eaves plate 8 are engaged with the tightening plate 7. However, in this case, in order to engage the tightening plate 7 and the engagement grooves 81 and 82, it is necessary to insert the eaves plate 8 into the tightening plate 7 from the end, so it is difficult to It is difficult to employ this insertion method depending on surrounding conditions such as structure.

Recently, an eaves unit was proposed in which a mounting plate is fixed to the outer wall of a building, and the upper and lower edges of the rear end of the eaves plate are engaged with the upper and lower edges of the mounting plate from the front and fixed with screws. (Utility Model No. 61-117822).

However, in the case of this eaves unit, the upper and lower edges of the eaves plate are simply screwed to the mounting plate, so the eaves plate is not crimped onto the mounting plate, and the bonding strength between the mounting plate and the eaves plate is low. Moreover, since the rear end portion of the eaves plate is not supported from below, it does not have sufficient load resistance. Further, since there are many screw-fastening points, there are problems in that the screw-fastening work takes time and the number of parts increases.

This invention is intended to solve the above problems.It allows one worker to easily install and construct the eaves plate, has excellent bonding strength and load capacity, and also simplifies screw fastening work and reduces the number of parts. The purpose is to provide an eave unit that can achieve this reduction.

<Means for Solving the Problems> The eaves unit of this invention includes a mounting frame 3 fixed to the outer wall of a building, an eaves plate 4 supported by the mounting frame 3, and an eaves plate 4 attached to the mounting frame 3. It consists of a tightening screw 34 for fixing.

The mounting frame 3 has vertically opposing engagement grooves 32 and 33 formed by bending the upper and lower edges of the mounting board 31 to the same side, and the lower engagement groove 33
The bottom of the groove is sloped low toward the mounting board 31 side.

The eaves plate 4 includes a mounting wall 42 at the base end, and an engagement protrusion 43 that engages with the upper engagement groove 32 is formed at the upper part of the mounting wall 42.
An engagement protrusion 44 is formed at the lower part of the engagement groove 2. The engagement protrusion 44 has a width smaller than the groove width of the lower engagement groove 33 and has an inclined surface on the lower surface whose inclination direction coincides with the groove bottom of the engagement groove 33. ing.

The tightening screw 34 is disposed at the bottom of the groove of the upper engagement portion 32 of the mounting frame 3 so as to be able to protrude and retract into the groove, and when the tightening screw 34 is tightened, the screw tip engages with the eaves plate 4. The protrusion 43 is urged downward.

<Function> After attaching and fixing the mounting frame 3 to the outer wall of the building using bolts, special nails, etc., place the eaves plate 4 on the front side of the mounting frame 3 so as to face each other, and first insert the upper engagement protrusion 43 into the engagement groove 32. Then, the lower engaging protrusion 44 is pushed into the lower engaging groove 33 and engaged. After that, when the tightening screw 34 is tightened, the tip of the screw enters into the engagement groove 32 and urges the engagement protrusion 43 of the eaves plate 4 downward, and the eaves plate 4 moves along the slope. While moving toward the mounting frame 3, it is crimped onto the mounting board 31. As a result, the mounting frame 3 and the eaves plate 4 are strongly connected, and the engagement protrusion 4
3 is engaged with the lower engagement groove 33, the load of the eaves plate 4 is stably supported by the mounting frame 3.

The illustrated eaves unit 2 includes a mounting frame 3 fixed to a building outer wall 11, an eaves plate 4 that is engaged and supported by the mounting frame 3, and an end that is engaged and held by both ends of the eaves plate 4. It is composed of a plate 5.

The mounting frame 3 is a molded body formed by, for example, drawing or extrusion processing of aluminum, and the upper and lower edges of the mounting board 31 have arbitrary length and width depending on the length and thickness of the eaves plate 4. Engagement grooves 3 are formed on the edge, bent at right angles to the same side, and further bent inward at the tips, and facing upward and downward.
2 and 33 are formed.

The mounting board 31 has fastening holes penetrating through it from the front and back at appropriate locations, and the mounting frame 3 is fixed to the outer wall 11 of the building using anchor bolts or special nails.

A plurality of tightening screws 34 are provided on the groove bottom of the upper engagement groove 32 at appropriate intervals in the longitudinal direction so as to be retractable into the groove. 35 is inclined low toward the mounting board 31 side.

The eaves plate 4 is an aluminum molded body similar to the mounting frame 3, and is formed into a flat cylindrical shape depending on the width and thickness of the eaves. This eave plate 4 has an eave surface 41 on its upper surface that is sloped low toward the front side, and a vertical mounting wall 42 is provided at its rear end. The upper and lower edges of this mounting wall 42 are formed with engaging protrusions 43 and 44 having a depressed structure that engage with the respective engaging grooves 32 and 33 in the order of the upper and lower parts. 32, 33 and the engagement protrusions 43, 44, when the upper engagement protrusion 43 is engaged to the bottom of the corresponding engagement groove 32, the lower engagement protrusion 44 engages the corresponding engagement groove 33. The dimensional relationship is set such that it can be engaged from the front.

The upper end surface of the upper engagement protrusion 43 is formed into a curved surface 45 with a low thickness in the center over the entire length, and the screw tip of the tightening screw 34 is received at this curved surface 45. Eggplant.

The lower engagement protrusion 44 is formed to have a slightly narrower width than the corresponding engagement groove 33, and the lower surface is formed in the engagement groove 3.
The slope of the groove bottom 35 of No. 3 is made to match the slope of the groove bottom 35 of No. 3. As a result, when the tightening screw 34 is tightened, the tip of the screw enters into the engagement groove 32 and urges the engagement protrusion 43 of the eaves plate 4 downward, causing the eaves plate 4 to move along the slope. While moving toward the mounting frame 3, it is crimped onto the mounting board 31.

The end plate 5 is a cast molded body of aluminum or the like, and has a closing wall 5 that matches the end face shape of the eaves plate 4.
An engaging flange 52 is integrally formed on the periphery of the eaves plate 1, and is fitted onto both ends of the eaves plate 4 and fixed with screws.

If necessary, the eaves plate 4 in the illustrated example may be provided with a slide groove along the longitudinal direction of the lower wall to engage a runner, and blinds, hangers, decorations, etc. may be hung from this runner. It is possible.
