Abstract

PURPOSE:To keep fastening a base to floor surface, and save material cost and work cost without extraction and loosening, by using a screw part provided on the lower portion of a coach screw inserted in a vertical hole and screwed in the tapered hole part of a wedge. CONSTITUTION:In execution, a vertical hole 16 is first provided in a floor 1. Next, a bond is applied on a screw portion 7 of a coach screw 5 inserted into a spring washer 17 and a center hole 14 of a base 12, and then the distal end of the screw portion 7 is inserted into a cowl 8. The coach screw 5 is driven into the vertical hole 16 together with the wedge 8 to fit the wedge 8 in the concrete layer 2 part in the lower portion of the vertical hole 16 so that a proper amount of the upper portion of the coach screw 5 projects from the vertical hole 16. Then, the coach screw 5 is screwed into the tapered hole portion 10 of the wedge 8 to expand the portion 10 so that the lower end edge 18 of a slit 11 is divided and the lower portion of the wedge 8 is press fitted in the concrete layer 2 of the vertical hole 16 by the slit 11, while the base 12 is fastened to a floor 1 through a washer 17 by the screw 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a base body of a gaming chair installed in a gaming machine such as a pachinko machine and a sled construction method.

[Conventional υ technology]

Conventionally, the construction of the base body of a game chair is carried out on a game floor 2t in which marble stone slabs 23 are laid on a concrete layer 2/j with a sandy layer 22 interposed therebetween, as shown in FIG. 5, for example.
First, a relatively large diameter shaft 2St whose lower part is immersed in the concrete layer 21 is drilled in the floor 2H, and screws 2 are inserted over the entire length.
1
Next, pour the bond 2g' into the gap formed by the anchor bolt 27 and the adjusted hole 2s, wait for the bond 2S to harden, and insert the center hole 30 of the game chair base body pace 2 into the upper part of the anchor bolt 27. 2? The Base Co. 9 was tightened to the floor 2 by screwing the γ-n η-bolt 27 into the nut 3/.

[Problems that the invention attempts to solve]

However, with the technique described above, not only is the material cost increased by requiring a multi-layered V-shaped core between the anchor port core, the hole-forming core, and the cFIJ, but it also takes a considerable amount of time to solidify, e.g. It took a long time to complete the construction, which caused the problem of increasing the amount of yellow.

Therefore, inventively, the material cost can be reduced.

A game chair base body and 70 construction methods that can be constructed in a short time and requires less construction cost! In order to solve the problem of υ in the prior art, we provide the following information: '1) (tJ).

[Small means to solve problems]

In other words, the first υ invention is concrete Mk, VC.

In a playground floor in which stone slabs are laid through a sandy layer, the floor, ? 1. Center 71 of the base for supporting the game chair arranged in
Open the coach screw with one thread on the fft+ marking floor, insert it into the hole inserted in F-13, and insert the screw part provided at the bottom of the coach screw into the hole V. A game chair base body, characterized in that it is screwed into the tapered hole part to tighten the base plate to the floor, and the base body is press-fitted into the concrete layer after preparing the hole. It is the dust that is enlightening.

In this case, there is a small amount of bond between the coach fluff and the sword, so there is no difference.

In the first invention, in a floor for an amusement park in which a stone slab is laid on a concrete layer with a sand-like m' interposed therebetween, the lower part of the hole is first immersed in the separately mentioned concrete layer. Drill a hole in the floor marked 0, pass through the center hole of the base of the game chair base, and fit the curl into the lower tip. 1. Next, screw the separately specified coach fluff into the curl υ taper hole, press fit the lower part of the curl υ into the preformed concrete layer in an expanded shape, and tighten the base to the floor. This is a complete summary of the construction method for the base body of a game chair, which is characterized by pressure.

In case of stiffness, it is okay to apply some pound t-coating to the coach fluff and insert curls.

[For production]

For stiff game chair foundations, there is a soft sandy layer 1' on the floor.
Regardless of the intention, the coach fluff that presses the base to the floor expands the curls that trap and exaggerate the holes and is fitted into the concrete layer.

Coach 7 chestnut υ removal does not cause protrusion or relaxation, and stably maintains the above-mentioned base and floor edge tension state.

〔Example〕

Next, an embodiment of the invention will be described with reference to FIGS.

l is a floor for a game hall, and is a conc I+-1jk1. Lh
Marble stone plate 4 through sandy layer 3 with sand and cement powder! It is laid down.

5 is a coach fluff with a head 6 at the hem and a slit 7 at the bottom of the fluff, and 8 is a synthetic resin IE4QJ cylindrical curl having a closure piece 9 facing outward.

v1 door - A tapered hole lO is formed at the bottom of the router with the same diameter n, curl? (The IJT ten thousand parts are provided with a diametrical slit //. 12 is a game machine in which a tapered hole 13 for fitting a game chair on the t-plane and a center hole 13 are penetrated through the bottom of the hole. The chair base has a circular shape with the lower surface 15 formed in the form of a hollow. When installing, place it at the required position facing the floor.

First, the vertical hole 16 that sinks into the lower part of the concrete layer 2 is placed on the floor l.
to be drilled in

Next, spring washer 17 and center hole /
4! After applying bond to the scrive $7 that has the coach suffix that is inserted through it, insert the tip rR of the scriwa portion 70 into the curl ffK, and drive the stiff coach suffliff S together with the curl 1 into the hole 16 with a hammer to curl r. Hole adjustment/6 lower ff1
Concrete MJ of 1 Fits in the 16th position, coach screw 5υJ: Adjust the hole/b> and make it protrude by an appropriate amount (see Figure 2). In this case, the spring washer 17 and the coach crease in the center hole /g may be made in advance.

Next, use an impact wrench etc. to screw the foot screw into the taper hole F.
1610 is widened, and this causes the curling hole LJ near, riwato//lower edge/I to be separated, and the lower part of the curl is slit 9)//''1?, and the hole is adjusted in a bifurcated expanded shape. At the same time, it is press-fitted into the concrete layer, and the base 12 is attached to the floor via the spring washer 17 to the coach fluff S.

In addition, the game chair 1 is installed in the base/2cLJ taper hole 13.
9 (tJ taper-shaped lower end f! 620 is fitted.

In this construction state, even though there is a soft sandy layer 3 on the floor 1, the coach fluff 5 that presses the base 1 against the floor 1 expands the η-rule screwed thereon. Hole adjustment/6Q
J Concrete layer 2c IJ hole wall Ef, fitted in a vertical shape □, stiffness prevents the coach fluff 5υ from coming out or loosening n, base 12υ floor 1 edge stabilizes the above-mentioned pressure-shaped drum a

In addition, the lower surface/S of the base 12 is a medium chain shape and the lower surface 1s
(/i The peripheral part is strongly pressed to the floor 10k+ nφ, and this (tJ) strongly prevents the base 12cLJ from wobbling.

[Invention effect]

kfill! As shown in υ, in the present invention, in the construction state, the coach fluff with the base pressed against the floor surface expands under the curl υ that is screwed to this and is press-fitted into the perforated concrete layer, so that it cannot be pulled out. It is possible to stably maintain the tight state of the floor surface edge of the t-page without causing tension or loosening, which is different from conventional υ
This is different from the bolt fixing method by pouring a pound, because it does not require a large amount of V pound, which reduces the cost of protection, and when the construction is completed, there is no need to wait for the concrete to harden, so the construction can be completed in a short time, and the construction cost is reduced. Less is enough.
