Description

[Detailed description of the invention] The present invention is mainly applicable to unit buildings.

The present invention relates to a floor bundle installed between a floor beam support member and a bundle stone in order to prevent vibration and deflection of the floor member.

Conventional floor bundles are rigid as a whole and have a constant length, so the vertical length may change due to manufacturing tolerances of the floor bundle itself, and the floor beam support members and bundle stones installed on site may vary. Due to changes in the vertical distance due to construction tolerances, gaps may occur between the floor bundle and the floor joist support member or bundle stones, or the floor bundle may be too long and the floor joist support member may be forced to curve upward. Such inconveniences were likely to occur.

Therefore, in order to avoid such inconveniences, workers have to crawl under the floor and insert spacers into the gaps mentioned above, or scrape away the piles of stones. However, due to the fact that the work involved fine-tuning each of the many floor bundles, the workability was extremely poor, and this was a major cause of increasing the overall construction cost and construction period.

In view of these circumstances, it is an object of the present invention to provide a floor bundle that can extremely easily and quickly absorb the manufacturing tolerances and construction tolerances described above, and is effective in reducing construction costs and construction periods.

The characteristic structure of the floor bundle according to the present invention is that in the floor bundle interposed between the floor beam support member and the bundle stones, this is attached to the expandable and contractible cylindrical main body that constitutes the floor bundle. In addition to incorporating a spring that biases the floor beam into an expanded state, a section is attached for attachment to the floor beam support member, and a hardening material injection hole is also provided, and this configuration provides the following operational effects.

That is, the cylindrical main body is configured to be expandable and contractible, and the hardening material injected into the cylindrical main body through the injection hole allows the telescopic cylindrical main body to be connected to the floor beam support member and the bundle stones. Since it can be made into a rigid body in a state of reliable contact with the cylindrical main body, no matter how the distance between the floor beam support member and the floor bundle changes from place to place, the cylindrical body can be made rigid by adjusting the length by expanding and contracting the cylindrical main body. The upper and lower ends of the main body can be brought into reliable contact with the lower surface of the floor beam support member and the upper surface of the bundle stones, respectively, and changes in the separation distance can be dealt with extremely easily and quickly,
After construction, it can provide sufficient support strength and reduce construction costs.
This is effective in reducing construction time and improving quality.

In particular, the floor bundle according to the present invention has a cylindrical main body equipped with a spring that tensions and biases the main body, so that the upper and lower ends of this cylindrical main body can be easily attached to the floor beam support members and the bundle. This has the advantage that it can be brought into more reliable and strong contact with the stones, and that the effective supporting strength of the floor bundle can be ensured sufficiently large.

In other words, even if the distance between the lower surface of the floor beam support member and the bundle stone changes, in order to change the length of the floor bundle accordingly, the length of the cylindrical main body that makes up the floor bundle must be It is necessary to divide the cylindrical main body in the direction so that it can expand and contract, but when the cylindrical main body is divided in the length direction in this way, the hardening material injected into the cylindrical main body hardens. Until then, the weight of the upper cylindrical body constituting the cylindrical main body must be held fixed by a hardening material in an unhardened state or by a specially provided support member. In the former case, there is a risk that the upper end level of the upper cylinder may drop due to the weight of the upper cylinder, and in the latter case, the upper end level of the upper cylinder may be lowered, and in the latter case, the length of each cylinder may be lowered by using an extra support member. However, according to the present invention, a spring is installed inside the extensible cylindrical main body, and the elastic force of the spring causes the upper cylinder to move. Since the main body is configured to be pressed against the upper floor joist support member, the installation process is extremely simple, as the cylindrical main body is simply inserted between the floor joist support member and the bundle stones. Therefore, the upper end level of the cylindrical body does not fall during the hardening period of the hardening material, and the length of each cylindrical body is adjusted to the distance between each floor beam support member and the bundle stone. Finally, the cylindrical main body can be installed in a substantially uniform pressure contact state with the elastic force of the spring without requiring the complicated work of precise adjustment, and as a result, the upper end of the cylindrical main body and the floor beam support Due to variations in the length adjustment accuracy of the cylindrical body, such as gaps of various sizes occurring at the contact points with the bottom surface of the member, there is a risk that a relatively large t-value may occur in the effective shared load supported by each cylindrical body. The cylindrical main body can be easily attached with a suitable length, and the supporting load shared by each cylindrical main body can be averaged to obtain a strong support structure.

Embodiments of the present invention will be described below based on the drawings.

The floor bundle A has both upper and lower cylinders IA and IB attached in an expanded state inside a telescoping cylindrical main body 1 which is formed by fitting an upper cylinder and a lower cylinder 1B so that they can slide vertically. At the same time, a compression spring 2 is attached to close the lower cylinder body 1B.A rod-shaped body 3a, which is erected from the center of the bottom plate 1b, is passed through the upper plate 1a of the upper cylinder body, and the upper end of the rod body 3a is placed in a horizontal position. The mounting, which is secured by a stopper 3b, has a portion 3, and a hardening material injection hole 4 is formed in the upper plate 1a.

The stopper 3b prevents both cylindrical bodies IA and IB from being pulled out.

The floor beam support member 8 is provided with elongated holes 8a, through which the stoppers 3b can be inserted, at a plurality of locations in the longitudinal direction thereof.

The construction procedure is as follows.

After the plurality of cylindrical main bodies 1, which are in a stretched state by the springs 2, are artificially contracted, each stopper 3b is inserted into each elongated hole 8a, and then the main bodies 1 are bent at 90 degrees. The cylindrical main body 1 is rotated to be suspended and supported by the floor beam support member 8. After that, each injection hole 4 is inserted into the cylindrical main body 1 which has been returned to the extended state. A hardening material S such as mortar is injected and filled through...

When the installation of the support frame 9 on the foundation 10 is completed, the contraction of the cylindrical main body 1 and the discharge of the hardened material S are also completed, and the upper and lower surfaces of the cylindrical main body 1 are covered with the springs 2 and 2.・
With the elastic force of . . . , it comes into strong and reliable contact with the lower surfaces of the floor beam support members 8 and the upper surfaces of the bundle stones 11.

In this state, it goes without saying that the hardening material S is completely filled in the cylindrical main body 1.
