Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an openable / closable deck metal fitting.

[0002]

2. Description of the Related Art Recently, as an open space, a large number of wooden decks installed outdoors have been incorporated into public facilities and houses. Particularly in public facilities, there is a relatively large space, and wooden tables, chairs, etc. The number of items that are deployed and used for multiple purposes such as outdoor events is increasing. These wood decks are shown in Figure 22.
As shown in Fig. 2, it consists of a support leg with a plate attached to the bolt so that it can be adjusted up and down, a base consisting of joists placed on the plate and fixed, and a deck material of hard wood placed on the top of the joists. , The joists are mainly made of steel and have a hat-shaped cross section. In addition, the deck material has a constant width, has a continuous groove in the thickness center position in the length direction, and a small chamfer is applied to the corner portion.The deck materials are arranged in the direction orthogonal to the joists and fixed with mounting brackets. .

As a means for fixing the joist and the deck material at this time, as shown in FIG. 23, an attaching hole is provided on one side of the lower surface of the fixing metal fitting having an H-shaped cross section so that the joist and the deck material intersect. Place the H-shaped fixing bracket at the position, fit the H-shaped fixing bracket that does not have the mounting hole into the groove of the deck material, and secure it to the joist with the tapping screw at the mounting hole. Furthermore H
Insert the next deck material into the side where the tapping screw of the mold fixing bracket is stopped, fix the opposite side of the deck material to the joist with the H type fixing bracket and tapping screw, and repeat the above work to assemble continuously. In other words, for the joists, only the H type fixing bracket is fixed with tapping screws, there is no direct fixing means for the deck material and joist, and the brim part of the upper part of the H type fixing bracket is set in the groove of the deck material. By inserting it without sticking, the deck material and joists are indirectly fixed.

Therefore, after the construction, the gap between the deck materials arranged side by side is the gap corresponding to the thickness of the vertical surface portion of the H-shaped fixing bracket,
This gap is necessary to help prevent ventilation and moisture under the floor, and it is usually about 4 mm to 6 mm.
In addition, the H-shaped fixing metal fittings and the tapping screws for mounting are not exposed on the deck surface after construction, which is excellent in design. This H-shaped fixing bracket is often made by cutting a short piece of aluminum extrusion, or by bending two stainless steel plates into a U shape and welding them back to back.

[0005]

However, since there is a gap on the surface of the wood deck as described above, when a small object or a thin object is dropped on the wood deck, it may fall below the floor through the clearance. Possible items are coins, banknotes, rings, necklaces, various cards, etc., and of course you must pick up those that have fallen. However, in the conventional construction method, the tapping screw for mounting and the H-shaped fixing bracket are completely hidden between the deck material and the joist, and after the deck material is constructed, the entire deck must be disassembled except for disassembly. A major problem is that the material cannot be removed.

As a method of coping with such a case,
A method is used in which a large amount of water is poured under the floor from the edge of the wood deck, and what is dropped is flushed out together with the water. There is no. Also partially H
There is also a method in which only the height is adjusted and the deck material is directly penetrated from the top surface of the deck material with a long tapping screw to fix it to the joist without using the mold fixing bracket, but the screw head is exposed and it is designed. In addition to being bad, it is difficult to pull out the tapping screw and lift and remove the deck material, and it is impossible to open any place because the place where it can be opened is limited, and similarly it is not satisfied at present. .

Further, the joist is not pre-drilled for screwing a screw, and a screw tapping screw whose tip is a drill is used, and a fixing method is performed by directly making a hole in one step. Is the most. Therefore, in the case of steel joists with a thin wall thickness, there is a risk that the screw threads will be crushed and run idle if the tightening torque is too strong due to the thread pitch of the tapping screw. However, fixing with screws is not always excellent. In addition, some screws loosened during long-term use after construction, and walking around that part caused the deck material to rise and fall, causing noise, and the deck material was partially damaged. Even in such a case, it is not easy to repair or replace only that part.

The present invention has been made to solve the above-mentioned problems, and after the construction of the wood deck, the fixing means between the deck material and the joist can be released by a simple work, and the deck material can be opened and closed or removed at any position. An object is to provide a possible deck material mounting bracket.

[0009]

In order to achieve the above object, the present invention has the following technical means. As a means for attaching the deck material to the joists, a pair of separation metal fittings is provided by combining two metal fittings, and the deck material is distributed and mounted on the deck material arranged in a face-to-face relationship. The separating metal fittings are a collar portion to be inserted into a groove provided at a central position in the thickness direction of the deck material, a vertical surface portion positioned in a gap between the deck materials, and a U-shape for positioning the upper surface of the joist. A fulcrum portion is provided at a position lower than the upper surface of the joist of the U-shaped portion while the U-shaped portion is covered with the joist.

Next, the U-shaped portion is placed on the upper surface of the joist in a state where the brim portion of the separating fitting is fitted in the groove of the deck material. At this time, the width of the groove and the thickness of the brim are set so that the brim can move in the groove of the deck material without rattling. Similarly, the separation metal fittings are similarly attached to the deck materials arranged adjacent to each other, and the deck materials are arranged side by side so that the separation metal fittings face each other and only the fulcrums of the U-shaped portions contact each other. At this time, the vertical surface portions of the separating metal fittings facing each other are not overlapped with each other, and the vertical surface portions of the separating metal fittings are allowed to enter each other.

When one end of the deck material in the width direction is lifted from the above-mentioned state, the separating metal fittings on the lifted side are separated vertically without interfering with each other, and the separating metal fittings on the opposite side are arranged such that their vertical surfaces are on each other. It enters into the gap part of the material, and the rotation operation is centered on the fulcrum of the U-shaped part that is in contact.
This action causes the upper corner of the deck material on the opposite side to abut the upper corner of the adjacent deck material, but at this stage the lifted side is somewhat floating and there is already space in the lateral direction. After that, by further rotating the deck material while adding the operation of pulling out the deck material in the lateral direction, the deck material can continue the rotation operation while sliding on the joists, and the deck material can be completely opened.

Therefore, it is advisable to set the position of the fulcrum of the U-shaped portion of the separation fitting, the thickness of the vertical surface portion, and the clearance dimension between the deck materials with respect to the thickness and width of the deck material to be used.
To lift the deck material, use a hook-shaped tip such as a shutter bar to hook the deck material near the center position in the lengthwise direction of the groove, and at first, lift it upward and gradually pull it sideways. You can open it smoothly.

Next, the separation metal fittings and the joists are fixed. However, since the condition is that they can be released after construction, the range that can be used for fixing is the gap between the deck materials. As the fixing means satisfying such a condition, there are means for fixing the joist and the separation metal fitting by sandwiching them with each other by rotating the eccentric part so as to attract and fix each other, and a joist on the tip of the elastic fixing metal fitting. Providing an engaging portion with the lower end of
A means to hold each other by using elasticity by pushing with a certain force or more, and a notch for tapping screw insertion in the part located in the gap of the separation fitting, and tapping screw directly from the top of the gap of the deck material by tapping screw. A fixing means using a tapping screw for fixing the separation metal fitting can be considered. With either method, the gap between deck materials must be used, and the joists that are located in the gap of the separation bracket must be fixed. It is advisable to provide a flat part.

As a means for rotating the eccentric portion and attracting and fixing the joist and the separation metal fitting, a plate-shaped L-shaped arm and a handle plate are provided, and a protruding portion and an R surface are provided at one end of the L-shaped arm. The other end is provided with a connecting hole for rotatably mounting the handle plate, and the handle plate is further provided with an eccentric portion having the connecting hole and a grip portion. The two L-shaped arms are arranged so that their connecting holes overlap each other so that they have a U-shape, and the connecting holes of the handle plate are also overlapped so that they can be rotatably assembled with pins to form an eccentric fixing bracket. . At this time, set the thickness of the pin insertion part where the L-shaped arm of the eccentric fixing bracket and the handle plate overlap so that it can be inserted into the gap of the deck material.

Next, the eccentric fixing metal fitting is put on the separating metal fitting so that both protruding portions of the L-shaped arm are hooked on the lower end of the joist, and at this time, the eccentric part is attached to the flat surface of the separating metal fitting. It is in a state of abutting, and at the same time as the handle plate is rotated, the eccentric part is also rotated, and while holding the grip part in the gap of the deck material, the joist and the separation metal member are pulled and fixed.

Further, in the fixing means utilizing elasticity,
A U-shaped fixing bracket with a thickness that can be inserted into the gap of the deck material is provided, and the tip of the U-shape is configured to expand slightly in the gap direction due to elasticity. Providing uneven portions or engaging portions. Make the inner dimension between the tip inner surface of the U-shaped fixing bracket slightly shorter than the outer dimension of both bottom ends of the joist. By pushing the U-shaped fixing metal fitting over the separating metal fitting and pushing it downward, the both ends are slightly opened and caught on the lower end of the joist, and the concave-convex portion or the protruding portion provides a retaining action with a certain strength. Also, it is advisable to hook the U-shaped fixing bracket with a rod-shaped one so that it can be removed from the gap between the deck materials after construction.

Further, when a tapping screw is used as the fixing means, a screw tapping screw having a drilled tip is used, and a notch portion for inserting the tapping screw is provided on the plane portion of the separating metal fitting so that the head of the tapping screw is attached. Make it small so that it can be inserted into the gap of the deck material, and fix it directly on the joist upper surface through the notch for tapping screw insertion. Therefore, the tapping screw fixing means also removes the tapping screw when releasing it, so that two facing metal fittings can be fixed at the same time by the flange surface of one tapping screw in order to reduce the number of tapping screws. By doing so, it is possible to reduce the number of steps when constructing or opening / closing the deck material.

With the above-mentioned structure, after releasing the fixing means, it becomes possible to open and close the wood deck at an arbitrary position one by one and re-fix it. However, the width of one deck material is relatively narrow, and opening and closing a plurality of sheets at the same time rather than opening and closing one by one will be less troublesome when it is desired to open a larger space.

Therefore, a means for simultaneously opening and closing a plurality of deck materials will be described. The collar and the vertical surface part have the same shape as the above-mentioned separation metal fittings, and the hinge metal fittings of the shape in which two separation metal fittings are rotatably connected at the fulcrum position of the U-shaped portion are provided, and the decks are lined up. Separation metal fittings and hinge metal fittings are alternately arranged in every other row of the material so that they are of the same kind in the same row, and they are fixed by one of the fixing means described above. Next, release the fixing means of the deck material to be opened, and lift the position near the hinge metal fittings upwards to separate the two separation metal fittings on both sides of the hinge metal fitting, and place the two metal fittings around the hinge metal fitting. The deck material is folded up in an inverted V shape and lifted. In this state, the separation metal fittings on both sides of the deck material have already been detached, and the two deck materials can be folded and opened by a lateral pulling operation from a position where they are raised to some extent. With the above configuration, it is possible to open and close a wide space at a time with less work.

Is placed in the gap 30 and the U-shaped portion 4 is placed over the joist upper surface 32. Therefore, the width of the groove 29 of the deck material 28 is
It is preferable to make it slightly wider than the thickness of the separation metal fitting 1 and to make the width of the U-shaped portion 4 slightly wider than the width of the joist upper surface 32. At this time, the width of the vertical surface portion 3 is set to be slightly less than half the width of the U-shaped portion 4.

FIG. 6 is a front view of the two separating fittings 1 facing each other as seen from the direction of the mouth of the deck material 28, and FIG. 7 is a state in which the separating fitting 1 and the deck material 28 are arranged on the joist upper surface 32. FIG. As shown in FIG. 6, a fulcrum 5 is provided at a lower position of the U-shaped portion 4 so that the fulcrums 5 of the separation metal fittings 1 facing each other abut each other. At this time, the distance between the tip of the fulcrum 5 and the distance from the side surface of the deck material 28 is twice the dimension of the gap 30 between the deck materials 28, and as shown in FIG. Keep the thickness of.

When the separation fitting 1 is assembled to the deck material 28, the state shown in FIG. 6 (a) is obtained. From the state shown in FIG. 6 (a), the collar portion 2 of one of the separation fittings 1 is moved laterally. Press
As shown in FIG. 7, the vertical surface portions 3 do not overlap each other,
Since only the fulcrum 5 of the U-shaped portion 4 is in contact with each other, the vertical surface portions 3 enter into the gap 30 with the deck material 28,
As shown in FIG. 6 (b), a rotation operation about the fulcrum 5 can be obtained.

Next, in the state shown in FIG. 7, the deck material 28 and the separation metal fitting 1 are continuously mounted on the joist upper surface 32, and the operation when one end of one deck material 28 is lifted upward is shown in FIG. It shows in order. When one end of the deck material 28 in the width direction is lifted from the state shown in FIG. 3 (a), the lifting metal fittings 1 on the lifted side are vertically separated without interfering with each other as shown in FIG. 3 (b).

Further, two flat portions 7 are provided with tapping screw insertion notches 25. FIG. 17 shows a state in which two separation fittings 1 according to the sixth embodiment face each other. FIG. 17
As shown in (a), the tapping screw insertion notch portions 25 at the central position are brought close to each other, and the tapping screw 24 is screwed from the upper portion of the gap 30 of the deck material 28 at this position, whereby the tapping screw 24 The brim surface 26 of the both presses the flat surface portions 7 of both of the separation fittings 1 at the same time, and one tapping screw 24 is used to press both of the separation fittings 1.
Can be fixed. Therefore, it is necessary to set the head of the tapping screw 24 so that it can be rotated by a screwdriver and can be inserted into the gap 30 of the deck material 28.

Further, similarly to the conventional fixing method, it is preferable to use a screw tapping screw having a drilled tip, and as shown in FIG. 18, the tapping screw 24 can be screwed at any position on the joist upper surface 32, and a usual tapping screw can be screwed. In the construction, if the joist 31 and the separation metal fitting 1 are fixed to each other only by the tapping screw 24 at the flat portion 7 at the central position of the separation metal fitting 1, the number of working steps can be reduced. Further, the fixing can be released by returning the tapping screw 24 and pulling it out. Of course, it is necessary to open the deck material 28 and then close it again to fix it again.

However, the position of the tapping screw 24 at the time of re-fixing is completely the same as the extracted position, and it is not always possible to re-fix without crushing the screw thread. There are some things you can't do.
In such a case, as shown in FIG. 17 (b), the tapping screw 24 may be screwed into another tapping screw insertion notch portion 25 provided in the flat portion 7 located outside. In other words, it becomes possible to fix at two new positions, and if the central position is included, it can be fixed at three positions and reliable re-fixing can be performed. In addition, when the tapping screw insertion notch portion 25 is plural, when the separation metal fitting 1 is screwed to the joist 31 at the time of construction, the torque is too strong and the screw thread is crushed, and the tapping screw 24 idles. It is also effective in cases such as when it happens.

With the above structure, the deck material 28 can be placed at any position on the wood deck after the fixing means is released.
It is possible to open and close one by one, and after the deck material 28 is closed, it can be re-fixed by a simple operation. In addition, the deck material 28 may be continuously opened,
A larger space can be opened at the same time, as long as the deck material 28 can be surely returned to the same place. However, if a large space is to be left open, the width of each deck material 28 is relatively narrow and it is quite troublesome to open the deck materials 28 one by one continuously. There are difficult points.

A means for simultaneously opening and closing a plurality of deck materials 28 is shown in FIGS. 19 to 21 as a seventh embodiment.
FIG. 19 is a perspective view of the seventh embodiment with the deck material 28 opened, and FIG. 20 is a front view of the operation of opening the deck material 28 as seen from the direction of the mouth of the deck material 28, and FIG.
[Fig. 6] is a top view showing the positional relationship between the separation metal fitting 1 and the hinge metal fitting 27 when the adjacent deck materials 28 are arranged with a constant gap. As shown in FIG. 20, the collar portion 2 and the vertical surface portion 3
Is the same as that of the first embodiment, and the fulcrum 5 of the U-shaped portion 4
A hinge metal fitting 27 having a shape in which two separation metal fittings 1 facing each other at a position are rotatably assembled in advance is provided. Next in FIG.
As shown in FIG. 1, the separation metal fittings 1 and the hinge metal fittings 27 are alternately arranged in every other row of the deck materials arranged side by side so that they are always arranged in the same row in the same kind.

As shown in FIG. 20 (a), when the fixing means is not provided and the deck material 28 is closed, the hinge metal fitting 27 is separated when the vicinity of the hinge metal fitting 27 of the deck material 28 is lifted. In order not to do so, as shown in FIG. 20 (b), while the hinge metal fitting 27 rotates, the deck materials 28 on both sides are simultaneously lifted. At this time, the separation metal fittings 1 located on both sides of the hinge metal fitting 27 are separated along the same trajectory as in the first embodiment.
As shown in 0 (c), the deck materials 28 on both sides are bent around the hinge metal fitting 27 and lifted up in an inverted V shape. As for the operation of completely opening the deck material 28, it is good to first lift it upward and gradually pull it laterally.
The two deck materials 28 can be folded and opened simultaneously.

FIG. 19 shows a state in which two deck materials 28 are lined up side by side, and a space of about four sheets can be opened by two operations. Further, in the hinge metal fitting 27 as well as the separating metal fitting 1, by providing the flat surface portion 7 in the portion located in the gap 30 of the deck material 28, the fixing means may be any of the above-mentioned means also in the seventh embodiment. Can be used.

However, in the seventh embodiment, as shown in FIG.
When using a random deck material 28 having a non-uniform length, a plurality of deck materials 28 are used for one deck material 28.
It will be lined up in a shifted state, and the hinge metal fitting 27 remains as it is
When the entire row is connected with each other, when one deck material 28 is lifted up, a plurality of deck materials 28 are simultaneously lifted up in a row, which hinders opening and closing. Therefore, in the seventh embodiment, it is advisable to arrange the deck materials 28 of the same length in an orderly manner as shown in FIG. 19. With this configuration, a plurality of deck materials 28 can be simultaneously opened and closed at any position.

When the random-sized deck materials 28 are randomly arranged, it is difficult to open and close an arbitrary position in the seventh embodiment. Therefore, the deck materials 28 having the same length are provided on a part of the wood deck. It is advisable to arrange them so that they are specified as opening and closing parts by arranging them side by side, and such parts are provided at several places on the wood deck. Further, by providing an opening / closing handle or the like on the deck material 28 of the opening / closing portion specified in the seventh embodiment so as to correspond to more frequent opening / closing,
It is also possible to develop different uses such as using the underfloor of a wood deck for storage.
