Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an eaves ceiling structure in which the lower surface of the eaves is covered with a plurality of plate materials serving as eaves ceiling plates.

(Prior Art) For a long time, in order to improve the appearance of the lower surface of the eaves of the building, it has been widely practiced to stretch and cover the eaves ceiling plate through a field edge or the like. Recently, there has been a strong demand for a fire resistant structure, and various fire resistant building panels have been used as the eave ceiling panel. It is general that such a plate material as an eaves ceiling plate is cut to a size from the side wall of the building to the eaves end, and is supported by a field edge so as to be parallel to the eaves end so as to cover the lower surface of the eaves. . The eaves gutter is attached to the tip of the eaves ceiling board in association with it, or the supporting material of the eaves ceiling board is buried at the rear end to finish the side wall of the building with mortar or the like.

(Problems to be solved by the invention) By the way, the eaves ceiling as described above is constructed by forming a frame such as a field edge on the lower surface of the eaves, and fixing and fixing each plate material to it. Is cumbersome and requires skill. In some cases, the eaves gutter is damaged after construction, and it may be necessary to remove the eaves ceiling plate at the same time when replacing or repairing it. Furthermore, when the eaves ceiling plate is partially soiled or decayed due to rainwater that has infiltrated on the upper surface of the eaves ceiling plate, it can be replaced as appropriate. In such a case, the eaves ceiling plate is composed of a series of continuous plates from the side wall of the building to the eaves, so if you remove this, some of the finishing material on the side wall of the building will also be removed and restored. Will be needed. Therefore,
Despite the fact that the part that needs to be removed is a part of the eaves side of the eaves ceiling plate, it requires such a large-scale repair work, resulting in high costs and waste of materials. Will occur.

The present invention has been made in view of the above, and is intended to provide a new eaves ceiling structure that is easy to construct and that allows the eaves ceiling plate to be removed to the minimum required even when the eaves gutter is restored. Is.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described with reference to the accompanying drawings. FIG. 1 is a partially cutaway vertical side view showing an embodiment of the eaves ceiling structure of the present invention, FIG. 2 is a similar view showing the construction procedure of the structure, and FIG. 3 is an exploded perspective view of the line III in FIG. Fig. 4 and Fig. 4 are exploded perspective views of line IV in Fig. 1, and Fig. 5 is first
FIG. 6 is a sectional view taken along the line V-V of FIG.
The figure is a vertical side view of another portion. That is, in the eaves ceiling structure of the present invention, a mounting bracket 1 is installed between the building side wall W and the eaves edge R at intervals, an eaves gutter 2 horizontally installed at the tip of the bracket, and the bracket 1 From the side of the eaves R, the first plate member 3 slidably inserted and held in contact with the side wall W of the building and the lower end portion of the eaves gutter 2 connected to the first plate member 3 are detachable. The second plate member 4 is fixed and fixed.

The first plate 3 is made of non-combustible plate such as asbestos calcium silicate plate, asbestos cement plate, magnesium plate, particle board, hard board, porous plate thereof, bending-reinforced metal panel and gypsum board, or wood. . also,
Each of the above plate materials can be used as the second plate material 4, but a porous metal panel is mainly used.

(Operation) The outline of how to construct the eaves ceiling structure having the above configuration will be outlined. First, the brackets 1 are installed between the building side walls W and the eaves R at intervals (see FIG. 2B). Next, the first plate member 3 is slidably inserted and held between the brackets 1 and 1 from the side of the eaves R so as to abut the side wall W, and the eaves gutter 2 is horizontally mounted on the tip of the bracket 1 [FIG. (See (b) and (c)). Finally, by fixing and fixing the second plate member 4 between the front end portion of the first plate member 3 and the lower end portion of the eaves gutter 2, the first and second plate members 3 and 4 are serialized. The eaves ceiling structure as shown in FIG. 1 is formed.

In such a structure, when the eaves ceiling plates 3 and 4 have partly decayed and need to be replaced, the second plate member 4 at the corresponding location is removed, and if necessary, the first plate member is removed. 3 eaves R
It is pulled out to the side and replaced.

(Example) Next, an example will be described. The bracket 1 in the example is
It is composed of a horizontal base rod 11 having an inverted H-shaped cross section fixedly fixed to the side wall W of the building and an eaves gutter holding rod 12 fixed and fixed to the tip end of the rafter R _1. The rod 12 is arranged in an up-and-down difference (the eaves gutter holding rod 12 is in an upper stage), and is connected and coupled to each other via vertical mounting pieces 111 and 121 connected to the front end and the rear end of each.

The eaves trough holding rod 12 includes an eaves trough receiving portion 13 formed in a shape that substantially conforms to the outer shape from the bottom surface to the rear wall of the eaves trough 2. Notches 131 and 131 are formed at two positions above and below the front end edge of the vertical portion of the receiving portion 13, and the protrusions 132 and 132 that are flush with the bottoms of the notches 131 and 131 and project to the left and right. Are formed. On the other hand, hook-shaped protrusions 22 and 22 for locking are vertically provided on the rear wall 21 of the eaves gutter 2, and when the eaves gutter 2 is received by the receiving portion 13, Notch 131, 13
1, and abuts the protrusions 132, 132. The eaves trough 2 is fixed by fitting the separately prepared C-shaped fitting members 14 and 14 including the hook-shaped projections 22 and 22 to the protrusions 132 and 132 in a close-fitting state. To be In addition, 132
As for the fitting mode between the fitting member 14 and the fitting member 14, various ones proposed in Japanese Patent Application No. 62-181457 (see Japanese Utility Model Laid-Open No. 1-86621) filed by the present applicant can be adopted.

As shown in FIG. 5, the first plate member 3 is held by inserting both side end portions into concave grooves 112, 112 formed in both side portions of the base rod 11. In this case, if the base rod 11 is visible from the bottom and this is not preferable in appearance, as shown in FIG. 6, the side end portion of the first plate member 3 is formed into a U-shape, and the concave groove 112, The lower part of 112 may be sandwiched, and when viewed from below, the first plate 3 may be connected in series so that only the plate 3 is visible. Since the first plate member 3 is held between the rafters R ₁ , when the bending becomes a problem, a metal core is embedded in the plate member 3, is inserted into a metal frame, or is attached between the rafters. You may reinforce by providing a rib in the direction and providing unevenness.

A rearward facing hook-shaped support piece 23 is hung on the front end of the bottom surface of the eaves gutter 2, and the second plate member 4 is connected to the first plate member 3 with the tap screw 41 interposed therebetween. It is fixed in place. An engaging groove 42 having a U-shaped cross section with a rearward opening is formed at a rear end portion of the second plate member 4, and the engaging groove 42 is engaged with a front end portion of the first plate member 3 in a vertically sandwiched state. It The groove width of the engaging groove 42 substantially corresponds to the thickness of the first plate member 3, and an enlarged portion 421 capable of holding the front end portion of the base rod 11 at appropriate places on the upper and lower groove walls thereof as shown in FIG. , 421 are formed, and a cutout portion 422 corresponding to the total thickness of the mounting pieces 111, 121 is formed in the upper enlarged portion 421. When the engagement groove 42 is engaged and connected to the first plate member 3, the enlarged portions 421, 421 hold the front end portion of the base rod 11 and the cutout portion 422 receives the attachment pieces 111, 121, The plate member 3 and the second plate member 4 can be connected in a close-fitting manner, and the rear end portion of the second plate member 4 is mainly the upper expanded portion 42.
It is supported by the base rod 11 via 1. Further, a large number of small holes 43 ... Are bored in the second plate member 4, and the outside air flows in through the small holes 43 ..., thereby suppressing the occurrence of dew condensation on the back of the eaves ceiling.

Thus, the eaves ceiling structure that is hidden by the series of the first and second plate members 3 and 4 and the eaves gutter 2 on the lower surface of the eaves and gives a simple and extremely novel image is developed.

FIG. 7 shows a connecting portion of the eaves gutter 2, the calling gutter 5 and the vertical gutter 6. That is, a right-angle elbow 51 is joined to the bottom of the eaves gutter 2, a substantially horizontal sluice gutter 5 is joined to the elbow 51, and a vertical gutter 6 is connected to the sluice gutter 5 via a right-angle elbow 61.
Are joined along the side wall W of the building. The above-mentioned gutter 5 is disposed on the first and second plate members 3 and 4 which are continuously connected,
A cutout portion 31 that receives the vertical gutter 6 is formed in the rear end portion of the first plate member 3. Therefore, when simultaneously constructing the gutter structure including the call gutter 5 and the vertical gutter 6, the
As the plate material 3, the plate material having the cutout portion 31 may be used. Further, in this gutter structure, the joint between the eaves gutter 2 and the gutter 5 and the gutter 5 are hidden by the eave ceiling in which the first and second plate members are connected. This is because the rod 11 and the holding rod 12 are formed in a stepped shape in the front-rear direction, and are preferably adopted in connection with the structure of the bracket 1. And in the unlikely event that the call gutter 5 needs to be removed, the second
If the plate member 4 is removed and the first plate member 3 is slid toward the eaves side, there will be no obstacles between the rafters R ₁ on which the call gutters 5 are arranged, and repair or the like can be easily performed. The side wall side of the first plate member 3 excluding the notch 31 may be supported on the building side wall W by a support piece such as an L-shape.

Reference numeral 24 in the drawing is a draining member, which is elastically mounted between the upper end of the eaves gutter rear wall 21 and the lower surface of the eaves edge R to prevent rainwater from entering the eaves lower surface.

Although not shown in the drawing, at the end of the gabled house, it is desirable to cover the entire eaves side with another cover including the end of the eaves gutter 2 via the bracket 1. In the case of a dormitory-type house, a retaining rod formed so as to be oriented at an angle of 90 ° is fixed to the rafters at the corners, and the horizontal base rods are arranged and fixed in a stepwise manner from the retaining rod. A corner joint is attached to the eaves gutters in different directions so that the eaves gutters are connected to each other, and a triangular plate member is held between the adjacent brackets to form a corner eave ceiling. Further, a non-combustible plate material may be interposed between the eaves gutter rear wall 21 and the eaves gutter receiving portion 13, or a non-combustible plate material may be attached to and integrated with the rear wall 21 to make the entire eaves ceiling structure a non-combustible structure. Is. Needless to say, other changes can be made without departing from the invention.

(Effect of the device) As described above, in the eaves ceiling structure of the present invention, the eaves ceiling plate is divided into two parts, the first and second plate members, and the first plate member is provided on the lower surface of the eaves at intervals. It is slidably inserted and held between the installed brackets, and the second plate member is detachably fixed between the first plate member and the eaves gutter. If it is necessary to remove this when repairing the eaves gutter or when the plate material is decaying, it is sufficient to remove only the second divided plate material, and the finishing material for the side wall of the building. It is possible to perform the process very easily and minimize the waste of material without the need to cut or repair the same. The present invention having such remarkable effects is of great practical value.
