Description

[Detailed Description of the Invention] This invention relates to a hardened cement eaves device that is strong, does not corrode, and can be used for a long period of time, to be attached to the entrance or upper part of a window of a building such as a concrete house or a prefabricated house.

Generally, this type of eaves device requires a carpenter to prepare a wooden base on-site, then cover the surface with galvanized iron sheets or apply mortar. Work was essential. In addition, recently some products have been manufactured using synthetic resin or steel plates, but these conventional products have the drawback of generating intense noise during rainstorms and being easily corroded by rainwater. At the same time,
The disadvantage is that the eaves are heated by the sun's heat and generate radiant heat.

Therefore, this invention is an attempt to improve the above-mentioned drawbacks, and its purpose is to provide an eave device that is easy and strong to install, and is robust and non-combustible. The main structure of the eave is the roof eave board, eaves board, fixing fittings, and left and right side covers. The roof eave plate is extruded in the longitudinal direction with hardened cement mixed with glass fiber or asbestos, etc., and a drain groove and a front wall are provided on the front inner surface of the roof eave plate, and a drain groove and a front wall are provided on the back surface of the front wall. form a locking groove. Further, at the rear end of the roof eave plate, a vertical bent portion and an inclined side are formed inside the lower end of the bent portion. The several fixing metal fittings that support and fix the roof eaves plate and attach it to the wall of the building are provided with an insertion protrusion at the tip to be inserted into the locking groove, and a stepped horizontal plate with a screw hole at the rear end. form a section. The stepped horizontal portion is provided with a vertically connected fastening portion, and an inwardly directed mounting piece is formed in connection with the fastening portion. The presser metal fitting that is applied to the stepped horizontal portion has an inclined abutment portion formed at its tip, and the metal fitting and the stepped horizontal portion are fastened with a clamp to secure the roof eave plate. be.
Therefore, according to this invention, there is no fear of corrosion over a long period of time, and the noise caused by wind and rain can be satisfactorily resolved.

Next, an embodiment of this invention will be explained with reference to the drawings. The eave body 1 is made of a roof eave plate 2 which is extruded in the longitudinal direction from hardened cement with glass fiber or asbestos mixed inside the cement, and an inorganic board plate or the like. It consists of an eaves ceiling board 3, a fixing fitting 4 that can be attached to and removed from a wall surface 22 of the building with a fixing device 21 such as an anchor bottle, and left and right side covers 7, 7 made of hardened cement. Said roof eave board 2
A rainwater drainage groove 8 is provided on the front inner surface in the longitudinal direction, and a locking groove 11 is formed on the back surface thereof. Further, at the rear in the longitudinal direction of the roof eave plate 2, there is formed a bent part 9 that comes into contact with the wall surface 22 of the building, and an inclined side 10 on the inner surface of the lower end of the bent part 9. Next, the fixing metal fitting 4 has an insertion protrusion 1 at its tip.
2, and a bent mounting piece 20 having a screw hole 19 on the lower side is formed. Further, at the rear end of the fixture 4, a stepped horizontal portion 13 having a screw hole 19 is provided, and a vertical fixing portion 14 is formed in connection with the stepped horizontal portion 13. Also, the fixed part 1
At the bottom of 4 is a mounting piece 24 with a screw hole 19 screwed into it.
is provided. The stepped horizontal portion 13 and the inclined side 10
The presser metal fitting 5 to be abutted and tightened has an inclined abutment part 15 formed at one end thereof. In addition, the parting edge 6 that attaches the eave ceiling board 3 to the fixing bracket 4 includes:
A horizontal portion provided with a screw hole 19 and a downwardly bent bent piece 16 are formed over the entire longitudinal length. Further, the side lids 7, 7 are integrally formed with fitting protrusions 17, 17 on the back surfaces thereof to fit into the roof eaves plate 2.
Reference numeral 18 designates a fitting such as a bottle or a nut for tightening the stepped horizontal portion 13 and the presser fitting 5.

This device has the above-mentioned configuration, and now to explain how to use this device, a roof eave plate 2 extruded from hardened cement is cut into appropriate lengths such as one length or half length. When installing this above an entrance, window, etc., several vertical fixing parts 14 are attached in advance to the wall surface 22 at predetermined intervals using fixing fittings 21 at suitable positions. Next, the roof eave plate 2 is fitted onto the fixing metal fitting 4 from above. And the stepped horizontal part 13
When the holding member 5 located at the upper portion is tightened with the fastener 18, the inclined side 10 provided inside the lower end of the bent portion 9 of the roof eave plate 2 is firmly pressed by the inclined abutting portion 15. The eaves ceiling board 3 is attached and stretched to a mounting piece 20 and a mounting piece 24 provided on the lower surface of the fixing fitting 4 with screws 23, 23 via the parting edges 6, 6. In addition, the side lids 7,
7 is fitted through an adhesive or the like.

As mentioned above, in this invention, the roof eave plate and side cover, which are the main components of the eave body, are molded using hardened cement mixed with glass fiber or asbestos, so it is strong and does not corrode, and does not rust or rust. There is no need to worry about discoloration, and it is also nonflammable.
It has the excellent effect of absorbing noise caused by wind and rain. Furthermore, by simply attaching a few fixing fittings to the building, the eaves main body can be easily and reliably constructed on site. Furthermore, a drain groove is formed on the front inner surface of the roof eaves board, and a locking groove is formed on the back side of the groove, which reliably blocks the flow of rainwater to the eave ceiling board side.
In addition, the locking groove reliably fits into the insertion protrusion provided at the tip of the fixing fitting, thereby having the effect of preventing movement of the roof eave plate. In addition, the bent part and the sloped side provided at the rear of the roof eave plate provide stable bonding to the wall surface, and also have the effect of making the roof eave plate stronger.
The slanted side is securely crimped with the presser fitting, and has the effect of being firmly clamped between it and the stepped horizontal part. Furthermore, since the eave ceiling boards are attached to the lower mounting pieces of the fixing bracket with screws through the facing edges, the installation is extremely simple and reliable, and the facing edges make the frame very beautiful. It has an excellent effect.
