TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor bundle that is vertically disposed via a slab or the like to support a building such as a house, and supports a base material such as a slab of the building.
[0002]
For example, in a wooden house, the floor portion of the house is supported by placing a support member made of wood or a metal material called a floor bundle between the floor and a floor supporting the floor portion of the house. It has a structure.
[0003]
[Prior art]
In the structure in which the floor is supported by the floor bundle, the floor bundle whose floor is fixed by the temporal change of wood such as warp or strain of the pulling or joist, or the floor is fixed to the floor, A gap often occurs between the slabs supporting the bundle and the floor bundle no longer fulfills its intended role. Further, in the case of a floor bundle not fixed as described above, the floor bundle itself may fall down.
[0004]
[Problems to be solved by the invention]
In view of such a point, there has also been provided a floor bundle in which a part of the floor bundle is formed into a screwed structure and, for example, the whole support height is adjustable by rotating a nut. However, in practice, adjusting the length of the floor bundle requires labor, such as workers having to go under the floor, individually adjusting the height of a large number of floor bundles, and having to regularly look under the floor. Is not a very effective solution.
[0005]
[Means for Solving the Problems]
The present invention has been made in view of the above problems, and accommodates an elastic body such as a coil spring in a floor bundle main body, and makes the floor bundle expandable and contractable by utilizing the elasticity of the elastic body. This is a floor bundle in which the floor bundle is always pressed against the frame material side.
[0006]
That is, the present invention includes a main shaft supported on the base portion side, and a frame supporting portion that is supported by the main shaft and abuts against a frame of a building to directly support the frame. An elastic body such as a coil spring is interposed between the support member and the main shaft, so that the support member is configured to always contact the support member by the elastic force of the elastic member. A bunch.
[0007]
Japanese Patent Application Laid-Open No. 2001-59330 discloses a configuration of a floor bundle in which a coil spring is housed, which obliquely urges a locking piece that locks to a screw rod, The height adjustment of the floor bundle itself, not the elastic body for supporting the load, is also based on the screwing structure of the bolt and nut. That is, the present invention is based on the premise that the height of the floor bundle is periodically adjusted manually and aims to facilitate this height adjustment work.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The frame support portion resists the resilience of an elastic body housed therein (hereinafter, a coil spring will be described as an example also including the embodiment), and is positioned closest to the top of the main shaft, that is, on the main shaft side. In a lowered state, it is fixed in advance to the main shaft using a locking means.
[0009]
In this state, the floor bundle is arranged at a predetermined position below the floor of a structure such as a house. The main shaft is screwed with the support cylinder side, and the floor bundle arranged at a predetermined position raises and lowers the main shaft with respect to the axial direction of the support cylinder by adjusting the screwing state, and a bridge member at the upper end of the main shaft. The height is adjusted so that the support portion contacts the frame.
[0010]
In this state, when the locking state of the locking means for fixing the support member is released, the support member comes into contact with the support member by the elastic force of the coil spring, and thereafter the support member is suspended from the ground by subsidence. Even if the distance from the member increases, the frame supporting portion abuts on the member by the elastic force of the elastic body and supports the member.
[0011]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2A and 2B.
First, mainly in FIG. 1, the floor bundle indicated by the arrow 1 is composed of the following components. Reference numeral 2 denotes a base portion, which is placed on a slab made of concrete ground or a concrete block or the like and which supports a frame member of a structure through the entire floor bundle 1.
[0012]
Reference numeral 3 denotes a spindle support portion, which is configured to be integrated with the base portion by being inserted into the base portion 2. Reference numeral 4 denotes a fixing ring which is formed in half when a flange 3a is formed with respect to the upper end edge of the spindle support portion 3, and is formed as an integral ring when the flange 3a is not formed. It is configured. In the configuration shown in the drawing, if the spindle support portion 3 is fitted into the spindle support portion insertion hole 2a of the base portion 2, a pair of half-fixed fixing rings are fitted from both sides of the spindle support portion 3, respectively. The main shaft support 3 is fixed to the base 2 by being inserted into an annular space between the main shaft support insertion hole 2 a of the base 2 and the main shaft support 3. When the flange 3a is not formed on the spindle support portion 3, the spindle support portion 3 is inserted into the base portion 2, and then the integral fixing ring 4 is inserted from the upper end of the spindle support portion 3. Insert into the part.
[0013]
Next, reference numeral 5 denotes a main shaft, 6 denotes a coil spring as an elastic body, 7 denotes a frame supporting portion, and 8 denotes an attachment between the frame and the frame supporting portion 7 by being attached to the top of the frame supporting portion 7. An interposed piece interposed therebetween, for example, which is made of wood or the like, and which is pressed into contact with the frame supporting portion 7 made of a metal material. Works to prevent damage. By setting the area of the interposition piece 8 to be larger than the top area of the support member 7, it is possible to distribute the pressure on the support member side.
[0014]
A male screw portion 5a is formed in the lower half of the main shaft 5, and an insertion hole 5b into which the frame support portion 7 is inserted is formed in the upper portion. Further, a pin sliding opening 5c (see FIG. 2A) having a substantially L-shaped side surface is formed in a side wall portion of the insertion hole 5b. The nuts 9 and 10 are screwed to the male screw portion 5a of the main shaft 5 having such a configuration, and the male screw portion 5a is formed on the main shaft support portion 3 in a state where the nuts 9 and 10 are screwed. By screwing into the female screw portion 3b, the entire main shaft 5 is supported on the main shaft support portion 3 so as to be adjustable in height. The reason why the nuts 9 and 10 are used to form a so-called double nut is to securely maintain this position after adjusting the height of the main shaft 5 with respect to the main shaft support portion 3, and although not so much as the double nut. A so-called single nut can almost achieve its purpose.
[0015]
Next, the coil spring 6 is inserted into the coil arrangement space 7a of the support member 7. The coil spring 6 has a total length longer than the total length of the coil arrangement space 7a in a state where no load is applied, and the coil supporting member 7 is exposed in a state where a part of the coil spring 6 is exposed from the supporting member 7. Is disposed in the insertion hole 5b of the main shaft 5. In the configuration shown in the drawing, the pin 11 is attached to the frame support 7, but the pin 11 is configured to be detachable, such as by screwing to the frame support 7. The support 11 is inserted into the main shaft 5 with the pins 11 removed from the support 7.
[0016]
When the insertion of the support member 7 is completed, the pin 11 is attached to the support member 7 through the pin sliding opening 5c of the main shaft 5. When the attachment of the pin 11 is completed, the support member is pushed down against the elastic force of the coil spring 6, and the pin 11 is moved from the position indicated by the reference numeral 11 'in FIG. ′, The support member 7 is rotated next, and the pin is placed at the position of the locking portion 5c ′ which is a horizontal portion of the sliding opening 5c. . As a result, the frame supporting portion 7 is fixed at the lowest position indicated by reference numeral 7 'against the elastic force of the internal coil spring 6, and is in a state of waiting for the attachment of the floor bundle 1.
[0017]
Next, the installation state of the floor bundle having the above configuration will be described.
The floor bundle 1 is placed under the floor of the house with the support member 7 fixed to the main shaft 5 side as described above, and is erected at a predetermined position by grounding the base portion 2 between soils. In this state, the nuts 9 and 10 are loosened, and the threaded state of the male screw portion 5a of the main shaft 5 and the female screw portion 3b of the main shaft support portion 3 is adjusted so that the intervening piece 8 at the upper end of the support member 7 can be used as a house material. The spindle 5 is raised until it comes into contact with.
[0018]
When the main shaft 5 is further rotated in a state where the interposition piece 8 is in contact with the frame, the frame support portion 7 that has been rotating together with the main shaft 5 is fixed to the frame side, and only the main shaft 5 is relatively moved. Rotate. As a result, the pin 11 of the frame supporting portion 7 moves from the horizontal portion to the vertical portion of the pin sliding opening 5c, and the locked state of the pin is released. As a result, even if the distance between the bridge and the soil is widened due to land subsidence or the like after the floor bundle 1 is installed, the bridge support 7 is always in contact with the bridge by the elastic force of the coil spring 6, The bridge can be supported.
[0019]
FIG. 3 shows a second embodiment of the present invention.
According to the present invention, it is possible to support the bridge for a long time by the elastic force of the coil spring 6, but it is not a normal situation that the distance between the bridge and the ground increases. Therefore, when this distance is opened by a certain value or more, it is necessary to notify the outside of this abnormal situation even if it can be supported by the floor bundle according to the present invention. In view of this point, in the present embodiment, a sensor is provided in the floor bundle 1 so as to warn when the distance between the frame member and the ground is larger than a certain value.
[0020]
In FIG. 3, an arrow 12 indicates a sensor. The sensor 12 includes a sensor body 12a and a movable rod 12b attached to the sensor body 12a. The sensor main body 12a is attached to a predetermined position of the main shaft 5. In addition, this attachment position is arranged, for example, at a position relatively lower than the vertical portion of the pin sliding opening 5c when an abnormality is to be detected early. The sensor body 12 is fixed to the main shaft 5 by screwing or the like.
[0021]
When the sensor main body 12a is mounted at a predetermined position, the movable rod 12b is set substantially horizontally, and is arranged so as to be substantially perpendicular to the vertical portion of the pin sliding opening 5c. In this state, the setting of the sensor 12 is completed.
[0022]
When the frame and the ground gradually separate from each other for some reason, the frame support 7 rises relative to the main shaft 5 corresponding to this state. In response to this rise, the pin 11 fixed to the frame support portion 7 also rises up the vertical portion of the pin sliding opening 5c, and finally comes into contact with the movable rod 12b to push up the movable rod 12b. To try. This push-up operation is transmitted to the sensor main body 12 as a rotation operation of the movable rod 12b, and a switch circuit in the sensor main body is turned ON to issue an alarm to the outside.
[0023]
The sensing system can be incorporated in a sensing system in, for example, a "wooden structure grounding environment monitoring improvement system" (Japanese Patent Application No. 2000-293326) previously proposed by the applicant or the like.
[0024]
【The invention's effect】
As described above, according to the present invention, the frame support can be constantly brought into contact with the frame by the elastic force of the elastic body, so that the frame can be firmly supported without maintenance for a long period of time. This makes it possible to significantly reduce labor and costs.
