Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device for a drain plate installed along a window frame.

Draining boards made of the same material as the sash are often used for windows fitted with aluminum sashes, and in the case of windows with wide openings, multiple drainage boards are connected to each other.

As shown in Fig. 1, the connection device for the draining plates is to weld and fix the angle members b, b to the back surfaces a', a' of the pair of draining plates a, a, and to connect the angle members b, b in a polymerized state. A structure in which a joint part c is formed by abutting against each other, and the abutting parts of a pair of angle members b and b are tightened and connected with a screw d, and the joint part c is filled with caulking material e.

As shown in Fig. 2, a member f with a grooved cross section is attached with screws g across the back surfaces a' and a' of a pair of adjacent draining plates a and a, and caulking is applied to the joint c in this member e. As shown in Figs. 3 and 4, a sealer is applied to the upper surfaces a'' and a'' of the joints of a pair of adjacent draining plates a and a.
A structure in which a connecting member i is fixed with a screw j via a screw j is known.

However, these connection devices require welding and screw fixing work when connecting the draining plate, making the connection very troublesome, and the cut surfaces of the screws g, j, sealer h, and connection member i are exposed to the outside. The problem is that the appearance may be damaged due to exposure to water.

Furthermore, since the joint width of the connecting portion is always constant in the above-mentioned connecting device, the draining plate cannot cope with expansion and contraction of the draining plate due to temperature changes or fluctuations in the joint width due to other causes, and the draining plate may become distorted.

Therefore, Publication No. 46-3965 (see Figure 5)
As shown in , a guide member k is attached to the back side a′ of the draining plate a.
and affixing the elastic sealing member l to the parts other than the guide member k, and crimping the elastic sealing member l to the connecting plate m between the guide members k and k of the adjacent draining plates a and a. A structure that fits and connects in such a way has been proposed.

With such a connecting device, adjacent draining plates can be relatively displaced to some extent, so expansion and contraction of the draining plates can be absorbed and distortion of the draining plates can be prevented. Since it is fitted into the guide member k while being compressed and deformed, the work becomes troublesome and the connection becomes troublesome.

This invention was devised in view of the above circumstances, and its purpose is to easily connect the draining plates, have a good appearance after connection, and furthermore prevent distortion of the draining plates when they expand or contract. An object of the present invention is to provide a connection device for a draining plate that allows the connection of a drain plate.

Embodiments of the present invention will be described below with reference to FIG. 6 and subsequent figures.

A pair of grooves 4, 4 for attaching an anchor are formed on the back surface 1a of one of the draining plates 1, and are continuous in the longitudinal direction and open opposite to each other. It is formed by a bent piece 8 bent into a substantially L-shape by the rising wall 7, and a hanging piece 9 provided opposite the rising wall 7.

A pair of similar grooves 4, 4' are also formed on the back surface 1'a of the other draining plate 1', but a ``''' is added to the reference numeral and the explanation thereof will be omitted.

In addition, the first joint component 2 has an L-shape that faces toward one draining plate 1 due to the vertical plate 10 and the horizontal plate 11 that serve as holding parts, and the vertical plate 10 has both ends facing toward the other draining plate 1'. The cover plates 12, 12 are each formed at right angles, and a protruding piece 13 is integrally formed on the vertical plate 10 at right angles toward one of the draining plates 1, and the upper surface 13a of the protruding piece 13 and the upper end surface 10a of the vertical plate are on the same plane, and the protruding piece 13 has a thin plate shape and is bent in the longitudinal direction (direction orthogonal to the vertical plate 10) to form a groove 14 in the middle part in the longitudinal direction. The groove 14 has an inclined side portion 14a,
14a and a flat bottom portion 14b, which is substantially parallel to the side plate 10, and has a width of the protruding piece 13.
L ₁ is slightly shorter than the distance L ₂ between the pair of grooves 4, 4 (that is, the distance between the inner surfaces 5a, 5a of the pair of vertical walls 5, 5), and the upper surface 1
3a and the lower surface 13b which is the bottom of the groove 14
L ₃ (that is, the sum of the depth of the groove 14 and the plate thickness) is the upper and lower opening width L ₄ of the groove 4 (that is, the upper surface of the rising wall 7).

A screw hole 15 is provided at the bottom 14b of the groove 14.
is drilled, and a screw 16 is screwed into the screw hole 15.

The second joint forming member 3 is a vertical plate 1 serving as a holding part.
7 and a horizontal plate 19 that serves as a receiving portion with an upwardly bent piece 18, it forms a substantially L-shape facing one draining plate 1, and this vertical plate 17 is longer than the vertical plate 10, and this horizontal plate 19 is The second joint forming member 3 is wider than the horizontal plate 11, and is longer and wider than the first joint forming member 2.

A protruding piece 13' formed in the same manner as described above is integrally formed on the vertical plate 17 toward the other draining plate 1'. Note that since this protruding piece 13 is the same as the above-mentioned protruding piece 13, a ``''' is added to the reference numeral and the explanation thereof will be omitted.

Since this is the case, the following procedure can be used to connect the draining plate 1 on one side and the draining plate 1' on the other side.

That is, with the screw 16 screwed into the screw hole 15 of the protruding piece 13 of the first joint component 2, the protruding piece 13
is inserted between the pair of grooves 4, 4 of one draining plate 1.

At this time, the protruding piece 13 is elastically compressed and deformed, and the upper surface 1
3a is in pressure contact with the lower surface 9a of the hanging piece, and the lower surface 13b is in pressure contact with the upper surface 7a of the rising wall.

After that, the screw 16 is tightened, the screw tip 16a is brought into contact with the back surface 1a of one of the draining plates, the lower surface 13b is pressed against the upper surface 7a of the pair of rising walls, and the protruding piece 13 is fixed in the grooves 4, 4 to form the first joint. The member 2 is attached and fixed to one of the draining plates 1.

Similarly, the second joint forming member 3 is attached and fixed to the other draining plate 1'.

Then, a pair of draining plates 1 and 1' are arranged opposite to each other with a predetermined gap, and the first joint forming member 2 is positioned above the second joint forming member 3, and the side plate 10 of the first joint forming member 2 and the side plate 10 of the first joint forming member 2 are side plate 17 of the second joint component 3;
The horizontal plate 19 constitutes a substantially concave joint A, and a back-up material B,
The upper part is filled with sealing material C. At this time, the pair of cover plates 12, 12 of the first joint forming member 2 prevents the sealant C from flowing out.

In other words, as shown in FIG.
is located at the middle in the width direction and above the horizontal plate 19 of the second joint component 3, and gaps are created between the horizontal plate 11 and the bent piece 18 and between the horizontal plate 11 and the horizontal plate 19, and the first , the second joint forming members 2 and 3 are spaced apart and facing each other to form a substantially concave joint A, and a backup material such as wood or vinyl chloride is placed at the bottom of the joint A to cover the gap. Fill with B and make horizontal piece 1
1 and the backup material B are brought into contact with each other,
The remaining upper part is filled with sealant C and the pair of draining plates 1 and 1' are connected.

As described above, the protruding pieces 13, 31' provided on the first joint forming member 2 and the second joint forming member 3
The vertical distances L ₃ and L ₃ ′ (that is, the thickness) of the concave groove 1
4 and 14', the plate thickness can be made smaller than the upper and lower opening widths of the grooves 4 and 4', so the protruding pieces 13 and 13' can be easily inserted into the grooves 14 and 14'. . In addition, in the embodiment, the protruding pieces 13,
Side portions 14a of grooves 14, 14' formed in 13',
14'a is inclined, so this side part 14a, 1
4'a serves as a guide when inserting the protruding pieces 13, 13, making insertion even easier.

Further, the screws 16, 16' are screwed into the screw holes 15, 15' of the protruding pieces 13, 13' in advance, and the protruding pieces 13,
Since the tightening operation can be performed after inserting the screws 13' into the grooves 4, 4, there is no need to position the screws 16, 16' for insertion and screwing.
13' becomes easier to insert.

Further, since the screws 16, 16' are screwed into the screw holes 15, 15' in the bottoms 14b, 14'b of the grooves 14, 14', their tips 16a, 16'a are connected to the upper surfaces 13a, 13 of the protruding pieces. Since the screws 16, 16' can be screwed and supported by the protruding pieces 13, 13' by tightening them until they are at a position slightly below 'a', the screws 16, 16' will not fall off when inserting the protruding pieces 13, 13'. At the same time, after insertion, it is only necessary to tighten the screws 16, 16' by a small distance, and the screws 16, 16'
The tightening operation is easy.

Therefore, the above effects combine to produce the following effects:
A pair of draining plates 1,
1', the pair of draining plates 1, 1' can be connected easily and quickly, improving work efficiency.

Further, since the screws 16, 16' and the cut surfaces of the members are not exposed to the outside, the appearance is clean and beautiful.

Furthermore, a first joint component 2 attached to one draining plate 1 and a second joint member 2 attached to the other draining plate 1'
Since they are separated from and not directly connected to the joint component 3, if the draining plates 1, 1' expand or contract due to temperature changes or other causes, the first and second joint components 2, 3 will be relatively displaced and the joint will be damaged. Since the expansion and contraction can be absorbed by changing the width, the draining plates 1, 1' are not distorted.

In the above embodiment, the protruding pieces 13, 13' have screws 1.
6, 16' and screw together the protruding piece 1 with screws 16, 16'.
3, 13' were installed and fixed between the grooves 4, 4, 4', 4', but the protruding piece 1 was fixed without using the screws 16, 16'.
Due to the elasticity of 3, 13', grooves 4, 4, 4', 4'
It may be installed and fixed on.

Further, the first and second joint forming members 2 and 3 may each have a substantially L-shape, and the horizontal plates serving as receiving portions may be disposed opposite each other to form a substantially concave joint. They may be overlapped to form a substantially concave joint.

Moreover, a pair of cover plates 12 of the first joint forming member 2,
12 prevents the sealant C from flowing out, but the cover plates 12, 12 may be provided separately from the first joint forming member 2.

As described above, the present invention has the following effects.

Each of the protruding pieces 13, 13' is elastically inserted between the pair of grooves 4, 4, 4', 4' of each draining plate 1, 1', and the protruding pieces 13, 13' are separated by elastic restoring force. Since the draining plates 1 and 1' can be firmly connected, the protruding piece 1
3 and 13', the first and second joint constituent members 2 and 3 can be connected to the draining plates 1 and 1'.
Can be attached to each end of the

Since each protruding piece 13, 13' is formed with grooves 14, 14' that are substantially parallel to the vertical plates 10, 17,
Although the protruding pieces 13, 13' are made into thin plate shapes so that they can be easily inserted between the grooves 4, 4', the entire width is hardened and reinforced by the grooves 14, 14', increasing the strength in the width direction. When inserted between the pair of grooves 4, 4, 4', 4' by elastic deformation, the protruding pieces 13, 1
3' is not locally deformed in the width direction, and the first and second joint forming members 2, 3 can be placed in close contact over the entire end portions of the draining plates 1, 1'.

In addition, the grooves 1 formed in the protruding pieces 13, 13'
4, 14' are a pair of inclined side parts 14a, 14
a, 14'a, 14'a, this side 1
4a and 14'a serve as guides when inserting the protruding pieces 13 and 13', so the above-mentioned protruding pieces 13 and
Coupled with the fact that the thickness of the protruding pieces 13' can be reduced, it becomes easier to smoothly insert the protruding pieces 13, 13' between the pair of grooves 4, 4, 4', 4'.

Therefore, the above-mentioned factors combine to make the first and second joint constituent members 2, 3 cut into draining plates 1, 1'.
Since it can be easily attached to the end of the drain plate, the pair of draining plates 1 and 1' can be easily connected and work efficiency can be improved. The sealing material C filled in the joint part A does not cause cracks and can be reliably sealed for a long period of time.

Further, since the pair of draining plates 1, 1' are not directly connected, distortion of the draining plates 1, 1' can be prevented when the draining plates 1, 1' expand and contract due to heat.

In addition, the backup material B is the first joint forming member 2.
There is no leakage from the concave joints in contact with the vertical plate 10, horizontal plate 11, pair of cover plates 12, 12, and vertical plate 17, horizontal plate 19, upward bent piece 18 of the second joint component 3, The back-up material B can be easily installed and the sealing material C can be installed, which simplifies the work, and even if the pair of draining plates 1 and 1' expand and contract due to heat, the back-up material B will not leak and the seal will break. This can be prevented.
