Abstract

<P>PROBLEM TO BE SOLVED: To provide a member which adequately possesses a strength high enough to bear a major load, in terms of a floor post which is installed on a foundation under the floor of a building so as to support a sleeper. <P>SOLUTION: A circularly constituted uneven surface 4 is formed around a central part of a sill board 1; a base end of a screw rod 5 is fixed to the central planar part of the uneven surface; a disc 6, which is composed of a proper thickness and a proper size, is fixed to the base end of the screw rod and the central planar part of the uneven surface; a circularly constituted uneven surface 12 is formed around the central part of a striker plate 10; a base end of a screw rod 13 is fixed to the central planar part of the uneven part; a disc 14, which is composed of a proper thickness and a proper size, is fixed to the base end of the screw rod and the central planar part of the uneven part; and the respective upper and lower screw rods are screwed into spiral parts which are formed in upper and lower inside parts of a pipe material whose central peripheral surface part is formed in a hexagonal shape. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a floor bundle installed on a foundation under a floor of a building to support a pulling.
[0002]
[Prior art]
In recent years, in prefabricated houses, turnbuckle type has become widespread as a simple means for the structure under the floor, but cracks and distortions occur in the receiving plate and base plate due to the load on the bolts during use Therefore, in view of the fact that the original function of the floor bundle could not be fulfilled, an increase in the strength has been a technical problem. As a conventional technology relating to a turnbuckle type floor bundle, for example, a device such as Utility Model Registration No. 3031622 can be found.
[0003]
[Problems to be solved by the invention]
In view of the above, an object of the present invention is to provide a floor bundle having a reinforcing mechanism that reinforces upper and lower bolt portions that receive a large load.
[0004]
[Means for Solving the Problems]
According to the present invention, a circular concave-convex surface is formed around a central portion of a base plate, and a proximal end of a screw is fixed to a central plane portion of the concave-convex surface. A disk having an appropriate thickness and size is fixed to the central plane portion, and a circular convex and concave surface is formed around the central portion of the seat plate. The base end of the screw is attached to the central planar portion of the concave and convex surface. A disk having an appropriate thickness and size is fixed to the base end of the screw rod at the center plane of the uneven surface, and the upper and lower screws are connected to the upper and lower ends of a tube having a hexagonal central peripheral surface. It is formed by screwing into a spiral part formed on the inner part.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The load pressure of the building, which is now applied via the pulling plate attached to the seat plate, is distributed from the center of the seat plate to a circular uneven surface in a ripple-like manner and can be uniformly received. Since the disk is integrally fixed without any gap, a strong durability is exhibited.
[0006]
Similarly, also on the base plate, the center portion of the base plate is dispersed in a rippled shape on a circular uneven surface and can be uniformly received, and a disk is integrally fixed to the center portion without a gap. By doing so, it will exhibit strong endurance.
[0007]
【Example】
Reference numeral 1 denotes a base plate provided with nail holes 2 and adhesive flow holes 3... Around the center of the base plate, and forms a circular concave and convex surface 4 for reinforcement around the center of the base plate.
[0008]
Reference numeral 5 denotes a screw rod having its base end fixedly mounted on the center plane portion of the concave and convex surface of the base plate 1, and the length of the screw rod is determined according to the length of the tube member 7 described later.
[0009]
Reference numeral 6 denotes a disk fixed at the base end of the threaded rod 5 to the central plane portion of the uneven surface of the base plate 1, which has an appropriate thickness and size.
[0010]
Reference numeral 7 denotes a tube having a spiral portion 8 into which the screw 5 is screwed. The central peripheral surface of the tube has a hexagonal shape and can be rotated by a work tool such as a spanner. The length of the hexagonal portion of this tube is arbitrary.
[0011]
In the tubular member 7, bulging portions 9, 9 are formed at the boundary between the hexagonal portion of the central peripheral surface and the spiral portions 8, 8 at the upper and lower inner portions thereof, to exert the reinforcing effect of the tubular member.
[0012]
Reference numeral 10 denotes a seat plate having an L-shaped side surface, and a number of nail holes 11 are provided around the seat plate.
[0013]
Reference numeral 12 denotes a reinforcing concave / convex surface formed in a circular shape around the center of the seat plate 10, and a screw 13 having a base end fixed thereto is erected at the center of the concave / convex surface. The length is determined according to the length of the tube 7.
[0014]
Numeral 14 denotes a disk fixed at the base end of the threaded rod 13 to the central plane of the concave and convex surface of the seat plate 10, which has an appropriate thickness and size.
[0015]
Numerals 15 and 15 are nuts which are screwed to the screw rods 5 and 13 via washers 16 and 16 to tighten the screw rods and the helical portion of the tube.
[0016]
【The invention's effect】
In the floor bundle according to the present invention, the large load of the building is evenly dispersed by the circular uneven surface and the disk provided around the screw rod particularly connected to the center plane portion of the seat plate and the base plate. It will be able to receive strongly, and it will be possible to perform prefabricated buildings safely and reliably.
