Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing structure for a hanging door body of a steel plate assembly building.

[Conventional technology]

The opening/closing door of a prefabricated building made of steel plates, such as a prefabricated storage shed, has a pair of left and right hanging door wheels attached to the upper end of the door body via mounting brackets, and the hanging door wheels are formed on an upper frame member that also serves as a lintel member. A hanging door type opening/closing structure in which the door body is suspended by supporting it on a protrusion (guide rail) and the door roller is rolled along the guide rail to open and close from side to side has been widely used. There is. In addition, in order to prevent the swinging of the hanging door type door body in the front-rear direction and to stabilize the installation posture of the door body, a guide groove is formed in the lower frame member that also serves as the threshold member, and a guide groove is formed in the lower frame member that also serves as the sill member. A guide member at the lower end of the
For example, it is common to have a structure in which a pair of left and right copying rollers are provided and the guide member is fitted into a guide groove.

[Problem to be solved]

The running end of the above-mentioned hanging door type opening/closing door body in the door opening direction is the corner post (or stud in some cases), and
The side of the pillar has a structure that doubles as a doorstop. Therefore, when opening the door, the side surface of the door body often strongly collides with the side surface of the pillar. If the door body collides strongly with the pillar, not only will the collision sound be noisy, but the repeated impact and vibration of the collision will cause cracks and peeling of the rust-preventive and decorative coatings on the steel plates that make up the door body and frame. . When the coating film of a steel plate is damaged, not only does the appearance and appearance of the building suffer, but the corrosion of the steel plate rapidly progresses from the damaged part of the coating film, significantly shortening the useful life of the building.

In view of the above, the present invention aims to provide an opening/closing structure that reduces the noise caused by collision with the door stop when the door is opened and the impact that is applied to the door and the frame.

[Means for solving problems]

In the present invention, hanging door wheels 52, 52 are mounted on the base plates 51, 51 near the left and right sides of the upper end, and guide members 6 are mounted near the left and right sides of the lower end.
The door body 40 to which the guide members 60 and 60 are attached is suspended so as to be able to open and close freely on the door guide rail 21 formed on the upper frame member 20 which also serves as a lintel, and the guide members 60 and 60 are attached to the lower part which also serves as a sill. In the opening/closing structure of a hanging door type door body of a steel plate assembly building in which the door body 40 is opened and closed along a guide groove 31 formed in a frame member 30, the door body 40 when the door is opened. An upper door stop member 80 against which the door roller board 51 collides is attached to the door roller guide rail 21 of the upper frame member 20 in order to stop the running of the door roller at a predetermined position.
A lower door stop member 90 with which the guide member 60 collides with the collision of the door roller board 51 with the upper door stop member 80 is attached, and the collision position of the door roller board 51 with respect to the upper door stop member 80 and the collision position with respect to the lower door stop member 90 is adjusted. The collision position of the guide member 60 is 3 to 7 points in the running direction of the door body.
It is characterized by being separated by mm.

[Effect]

In the present invention, the door body 40 includes the upper frame member 20
Upper door stopper member 80 attached to the guide rail 21 of
The door roller base plate 51 collides with the vehicle and stops running, and does not directly collide with a corner post or the like. When the door body 40 is opened forcefully, immediately after the door roller base plate 51 collides with the upper door stop member 80, the hanging door roller 52 of the door roller part momentarily lifts up slightly from the guide rail 21, and then As the lower end side of the door body 40 moves forward (the door body instantaneously assumes a slightly inclined posture), the guide member 60 relative to the lower door stop member 90 moves forward.
resulting in a collision. Immediately after the collision, the hanging door vehicle 52 is moved toward the guide rail 21 due to the weight of the door body 40.
Return to the state where you landed on top.

In this way, the door body 40 effectively reduces its running inertia due to the two-stage collision of the door roller board 51 against the upper door stop member 80 and the subsequent collision of the guide member 60 against the lower door stop member 90. It is absorbed and relaxed and stopped there.

Therefore, unlike the conventional structure in which a corner post or the like is used as a doorstop to stop the door from opening, the collision noise and impact/vibration applied to the door and the frame forming the entrance/exit are slight. Also, the door body 40 that was opened forcefully
The repulsive force of the collision rarely causes the door to reversely move in the closing direction, and it stably stops at a predetermined position.

Note that the door roller section 50 is a part that supports the entire weight of the door body and allows stable opening/closing movement, and the door roller board 51 is designed to be strong and robust. Although the resistance against the upper door stop member 80 is relatively low, it precedes the collision of the door roller board 51 with the upper door stop member 80, and the guide member 6
Since the structure is such that the zero collision occurs later, the impact applied to the guide member 60 is relatively small, and damage to the guide member 60 can be prevented and the guide function can be sufficiently maintained.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 10 indicates corner pillars, which are erected at both left and right ends of the front of the assembled building. The upper frame member 20, which also serves as a lintel, has a substantially C-shaped cross section on which the door car guide rail 21 is formed, and the lower frame member 30, which also serves as a sill, has a substantially C-shaped cross-sectional shape.
has a bent cross section in which a guide groove 31 for guiding the lower end of the door body is formed. Corner pillar 1 above
0, 10, the upper frame member 20 and the lower frame member 30 constitute a frame around the entrance/exit side of the assembled building.

50 is a door roller section. The door roller part 50 is a substantially L-shaped board 51 with a hanging door roller 52 rotatably mounted on a shaft 53, and is located on the left and right sides of the upper end of the door body 40 and is firmly fixed with screws 54 or the like. has been done.

Copying roller 60 installed as a guide member
are located on the left and right sides of the lower end of the door body 40 and are rotatably mounted on a shaft 61.

The door body 40 is movably suspended from the guide rail 21 of the upper frame member 20 via the door roller 52, and the copying roller 60 at its lower end is fitted into the guide groove 31 of the lower frame member 30. This prevents the door body from swinging back and forth when it is opening, closing, or stopping.

In addition, 70 is a side wall, which is located on the left and right sides of the frame and fixed to each side.

The upper door stopper member 80 is a plate-like member having a substantially L-shape, and its base 81 is placed on the back surface of the guide rail 21 at a predetermined position near the end of the guide rail 21 of the upper frame member 20. The tip portion 82 is fixed with screws 83 or the like so as to protrude from the top surface of the guide rail 21 in the horizontal direction.

The lower door stop member 90 is a box body formed by bending a painted steel plate into an inverted isosceles trapezoid shape with an open bottom surface, and has longitudinal cut-and-raise holes 92 on both left and right sides. A protrusion 91 is formed. The lower door stopper member 90 has protrusions 91, 91 in notch holes 32, 32 bored in both side wall surfaces of the guide groove 31 at a predetermined position near the end of the guide groove 31 of the lower frame member 30. It is attached to the lower frame member 30 by being fitted. The lower door stop member 90 is inserted into the notch hole 32 of the lower frame member 30,
32, the lower door stopper member 90 should be strongly pushed into the guide groove 31, and as a result of the pushing, the guide groove 31 elastically expands and the protrusion 91,
91 is fitted and fixed into the notch holes 32, 32. In this case, the lower door stop member 90 is embedded and fixed in the guide groove 31 so as not to obstruct passage of the rear portion of the door body 40.

The upper door stop member 80 is positioned and fixed to the guide rail 21 of the upper frame member 20 so that the door body 40 being opened can be stopped at a predetermined stop position by the collision of the door roller board 51, On the other hand, the lower door stop member 90 is positioned such that the copying roller 60 collides with the upper door stop member 80 after the collision between the door roller base plate 51, and the lower frame member 30 moves into the guide groove 31.
Fixed inside.

FIG. 2 shows the positional relationship between the two upper and lower door stop members 80 and 90 in which the copying roller 60 collides with the lower door stop member 90 after the collision of the door roller base plate 51 with the upper door stop member 80. It shows. In the figure, x represents the upper door stop member 80 and the lower door stop member 9 in the running direction of the door body 40.
0 is the distance between two fixed positions. The distance x is suitably about 3 to 7 mm. distance x
If it is smaller than that, the two-stage collision with a time difference will not have a sufficient shock-reducing effect on each component when the door stops, and an excessive impact will be applied to the copying roller 60 that collides with the lower door stop member 90. 7mm, which causes the damage to be accelerated.
If the separation is larger, the hanging door wheel 52 will rise more from the guide rail 21 when the door body 40 collides with the upper door stop member 80, and problems such as derailment and increased vibration of the door body are likely to occur. It is from.

In FIG. 2, the lower door stop member 90 is located on the left side closer to the door stop than directly below the upper door stop member 80 because of the door roller base plate 51 and copying roller 60.
This is because they are located on a vertical line and are attached above and below the door body 40. Of course, this is just one example, and the mounting positional relationship of the door roller board 51 and copying roller 60 with respect to the door body 40 (left and right in the drawing) It goes without saying that the lower door stop member 90 may be located vertically below and fixed to the upper door stop member 80, or may be fixed to the right side of the upper door stop member 80, depending on the relative positional relationship in the direction. stomach.

In the above configuration, when the door body 40 is run toward the corner post 10 side along the guide rail 21 of the upper frame member and the guide groove 31 of the lower frame member, the rear side attached to the upper end of the door body 40 Door wheel board 51
The end face of the door collides with the upper door stop member 80, and after a slight time lag after the collision, the trailing copying roller 60 attached to the lower end of the door body 40 collides with the lower door stop member 90, causing the door to close. The body 40 stops running at that position.

The door stop member 80 and the lower door stop member 90
The material may be made of metal, resin, etc., as long as it has the impact resistance, rigidity, etc. necessary for a door stop member. Further, their shape is not limited to the illustrated example, and any shape may be used as long as it can reliably stop the movement of the door body without interfering with the passage of the rear part of the door body when the door body 40 is opened and closed. It is.

Although the attached diagram shows an example of a double door type in which two door bodies 40, 40 are attached to open and close from left to right, the structure of the present invention can also be applied to other types such as a single door type with a single door. Needless to say, this can be applied.

[Effects of the invention] In the present invention, the opening movement of the door body is stopped by the upper door stop member attached to the upper frame member and the lower door stop member attached to the lower frame member. Unlike the conventional structure in which the side of the pillar is used as a doorstop and the entire rear side of the door body collides with it to stop it, the collision noise when the door body stops is small.
It is not the door itself that collides with the upper and lower door stop members that stop the movement of the door, but the supporting members attached to the door body (door roller board, copying roller, etc.), and the door due to the collision The impact on the body and structure is also minor. Therefore, conventional problems such as cracking and peeling of the steel plate coating due to impact are avoided, the original appearance and appearance are maintained, and the service life is improved.

In addition, since the door body is stopped by a two-stage collision of the door roller board against the upper door stop member and the collision of the guide member against the lower door stop member that occurs later, the running inertia of the door body is effectively reduced. Even if the door body is opened forcefully, there is little return (reversal movement in the closing direction) of the door body due to the repulsive force of the collision, and there is no need to worry about opening it again.

Furthermore, in the conventional structure, the side of the pillar is used as a doorstop, so the pillar needs to have a shape that has a side that becomes the doorstop.In contrast, in the present invention, the pillar has a side that becomes the doorstop. Since it is not necessary, the side surface may be partially cut out as shown in FIG. 1, and the weight of the assembly member and the material cost can be reduced accordingly.

Moreover, in the conventional structure where the side of the pillar is used as a doorstop, it is necessary to consider the mutual relationship between the width of the door body, the opening/closing distance, the width of the wing wall, etc.
In the present invention, the positions of the upper and lower door stop members can be determined appropriately, so there is no restriction as described above, and there is a large degree of freedom in design. Since both the door stop member and the stopper member are constructed of small parts, they are inexpensive and easy to install.
