Abstract

PURPOSE:To set each vertical plate to optional height by installing a horizontal insert hole in each corresponding spot of both section U-shaped vertical plates, inserting a support plate in the horizontal direction after piercing through both insert holes, and screwing a nut in a bolt leg in the vertical direction of a bottom plate. CONSTITUTION:Two horizontal linear insert holes 12 and one short insert hole 12' are installed in each vertical plate 11 at both sides of a semicylindrical bundle body 1 opened upward, and each through hole 13 is installed on the insert hole 12. In addition, an insert hole 16 is installed in the center of a bottom plate 15, and a stopper 17 is formed at both sides of it. Next, a bead 21 is additionally installed at both sides of the insert hole 16 installed in the center of a rectangular steel plate, setting it down to a support plate 2, and a presser plate 20 provided with the insert hole 16 at the center is prepared for. Then, the support plate 2 is inserted into the insert hole 12 of the bundle body 1, and respective insert holes 16 of a nut hole, the bottom plate 15, the presser plate 20 and the support plate 2 are aligned, then a nut 31 is screwed after making a bolt leg 32 so as to be insertable, thus a bundle 3 is completed. With this constitution, level control can be done even after floor joists 4 are set up.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a double-bedded east.

[Conventional technology]

A bolt is attached to the bottom of a metal fitting with a U-shaped cross section that opens in the L direction, and the bolt is fitted into a nut embedded in the floor to make height adjustment possible. There is.

[Problem that the invention seeks to solve]

The height of this bundle is adjusted by rotating the upper metal fitting itself to change the degree of screw engagement, and it is impossible to adjust the height after installing the joists. Ta. In addition, in order to increase the range of height adjustment, long bolts and nuts must be used, which means that they are expensive, resulting in increased costs.

Means for Solving the Problem] In order to solve this problem, the present invention has a horizontal straight line inserted into the corresponding part of the compatible plate having a U-shaped cross section and opening upward. A hole is provided, a horizontal support plate is inserted through both insertion holes, and 1. Attach a nut that penetrates in the vertical direction, and screw the bolt leg into the throat.

[Effect]

With this configuration, the vertical plate can be set to any desired height, so by attaching the nut to the lower end of the vertical plate, the bolt leg can be moved up and down more widely, thus increasing the range of height adjustment. be able to.

Furthermore, since the height can be adjusted by rotating the bolt leg, it is convenient to be able to adjust the height even after the joist is installed.

[Example 1] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Mold Body 1 As shown in FIG. 1, the mold body 1 is formed by forming a galvanized steel plate with a thickness of 2.3 mm into a single cylinder with an upward opening. Two straight horizontal insertion holes 12 and one short insertion hole 12'' are provided in the vertical plate 11 on both sides.Insertion hole 12
An X through hole 13 is provided at a predetermined distance above. A shallow ■-shaped recess 14 is provided at the upper edge of the two upright plates. As shown in FIG. 2, an insertion hole 16 is provided in the center of the bottom plate 15,
Stoppers 17 are formed on both sides by bending part of the bottom plate upward.

! As shown in Fig. 3, a galvanized steel plate with a thickness of 2.3R is formed into a rectangular shape, with an insertion hole J6 in the center, and beads 21 on both sides of which the plate is raised in the insertion direction. is attached to form the support plate 2.

Holding Plate 20 As shown in FIG. 4, a holding plate 20 made of a rectangular bent steel plate having a thickness of 2.3 mm and having an insertion hole 16 in the center is prepared.

As shown in FIG. 5, a nut 31 is dropped between the stoppers 17 at the bottom of the mold body 1. Short insertion hole 1 in mold body
2', insert the holding plate 20 and fix the bottom.

The support plate 2 is inserted into the insertion hole 12 on the lower side of the mold body.

The support plate is made to protrude from both sides of the vertical plate of the mold body, and the positions of the nut hole, the insertion hole 16 on the bottom, the insertion hole 16 of the holding plate, and the insertion hole 16 of the support plate are aligned.
can be inserted. Natsuto 31 has Boruto 3
Combine 2 to complete bundle 3. It is convenient to provide a screwdriver 'a33 at the upper end of the bolt leg. The lower end is covered with a cushioning material 34 such as rubber.

Joist 4 As shown in FIG. 5, a downwardly opened hat section 40 is externally fitted from the seventh of the plurality of bundles 3 arranged in a straight line, the flange 41 is supported by the support plate 2, and the web 42 penetrates. A connecting rod 43 is passed through the hole and the through hole 13 of the standing board to connect the joist material and the bundle to form the joist 4.

A screwdriver for the bolt leg through the operation hole 45 provided on the one side 44 of the hat-shaped 6!140 and the bundle! It is convenient because the height can be adjusted from the top of the joist by inserting a screwdriver into 33 and rotating it.

Adjacent joists and joist flanges 4 formed in this way
A flat floor plate is installed between the two floors to form a double floor.

Since the distance between the bottom surface of the mold body 1 (bottom surface of the nut) and the top surface of the hat section steel 40 is large, the height can be adjusted over a wide range.

If you want to further widen the adjustment range, you can insert the support plate into the insertion hole on the upper side of the standing plate. To make it bigger,
As shown in FIG. 6, the bundle 4 may be rotated 90 degrees and the hat section 40 may be placed in the dish-shaped recess 14 at the upper edge of the mold body.

As shown in FIG. 7, a square timber 5 may be fitted between two standing boards 11 of a bundle 3 and supported by a support plate 2 to form a joist 4. The square timbers are fixed with screws 46 passed through the through holes 13. The square timbers may have vertical operation holes drilled in them, or short square timbers may be connected at the 7th edge of the bundle, and Pol HI
In the area above JII, it may be installed with a gap between the square timbers, leaving a space above and below. This is convenient for adjusting the height by parking the screwdriver through the operation hole or gap.

In order to absorb the sound of the floor, methods such as pasting double-sided adhesive tape or pasting a thin sheet of cushioning rubber on the top surface of the support plate may be used.

Alternatively, the mold body may be formed separately from two upright plates.

[Embodiment 2] Double bundle 30 As shown in FIG. 8, a double bundle 30 can be formed by inserting the mold body 11 into both sides (1!I+) of the long support plate 2.

Since the two bundles are connected, it is convenient because the bundle is stable.

By installing the double bundles in a staggered manner, it is possible to create a structure in which all the joists are connected by support plates.
A joist with high malleability can be constructed.

Also, as shown in Figure 9, there is a long, dish-shaped depression 2 in the middle.
A double bundle 30 is formed using support plates 2 provided with 2, a joist 4 is formed by fitting a hat section steel 40 onto each bundle, and a floor board 6 is installed between the joists to form a double floor. Configure. If the partition plate 23 is installed over the dish-shaped depression, the underfloor space 7
is divided into upper and lower parts.

It is convenient to be able to separate the lines.

〔effect〕

Since the present invention is configured as described above, it has the following features.

■ A large east can be created while adjusting the height.

■ The method of producing bundles is extremely simple and can be obtained at low cost.

■ By using thick steel plates and forming high standing plates,
Easy to form strong bundles for raised beds.

■ Since support plates can be protruded from both sides of the bundle, joists can be fitted externally to the standing boards, or joists can be fitted internally between the standing boards.

■ A double bundle can be formed by lengthening the support plate.
A stable joist can be formed. Furthermore, it becomes possible to easily divide the underfloor area into upper and lower sections.
