Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a simple nut for engineered spansion bolts, and more specifically, a screw nut for an engineered spansion bolt that is screwed into a wall, such as a wood screw, that passes through an object to be attached to a wall surface, and is fixed by tightening the screw. This relates to a nut cylinder whose portion expands radially outward and is defined by tK&.

Conventionally, nut tubes for this type of engineer's bolts have a uniform cross-sectional shape as shown in Figs. 1 and 2, and nuts with both front and rear ends as shown in Fig. 3. The remaining peripheral wall is divided in the circumferential direction by slits (3) K.

The conventional nut cylinder (11) shown in Figs. 1 and 2 takes advantage of the fact that the outer diameter expands due to the screw inserted into the nut cylinder (1), and the inner JIK outer periphery of the hole drilled in l! This method is suitable for hard walls, such as cosiclete walls, as the bonding force with the wall is high, but for soft walls, for example, lightweight foamed coscrete walls. (ALC) against 17, Natsuto a 11
The wall itself deforms over a long period of time due to the radial outward force received from the hole, making it impossible to maintain the state in which the outer periphery of the nut is in pressure contact with the hole for a long period of time. The problem was that I couldn't do it. Also, the conventional nut cylinder (!) shown in Fig. 3 has a screw K screwed into it.
Therefore, the tip is divided into a plurality of parts by the slit Ti1lK, and the divided part is moved outward in the radial direction by tightening the screw, and this divided part comes into pressure contact with the inner periphery of the hole provided in the wall. Since the tip has a large - point, it can be held securely even on soft walls. However, as shown in FIG.
The part of the fragment (6) that opened wide outwards was initially fixed to the wall (4) by digging into the back of the hole (4) around the wall hole (7), but As time passes, the soft wall material itself is compressed and deformed by the force from this biting part, and the engagement between the nut cylinder (2) and the wall 14+ becomes loose, and as a result, the screw (b) becomes loose. , key screw (6)
Even if you try to tighten it, the nut cylinder +
21 rotates idly, making it impossible to securely fix the member (8:) to the wall surface.In order to overcome the above-mentioned problems, recently, a structure with a shape as shown in Fig. 5 has been developed. A nut cylinder (lα) is provided. This nut cylinder α
o) As shown in Figs. 5 and 6, the front cylinder (1) and the rear cylinder (03) are integrally continuous via an intermediate ring, and the intermediate cylinder (03)
1 is formed into a shape divided in the circumferential direction by slits +s+K running in the longitudinal direction. And in this Natsutotsutsukoi, from the front Th + river to the middle tube (l: 1 through the rear tube 02
As the screw (6), the tip of which is inserted into the Each strip (14) of the intermediate cylinder O1 is bent at a position protruding outward in the radial direction, and a portion of each strip portion is engaged with the back surface of the periphery of the wall hole (7), thereby forming a thin wall (
4) K also has a structure that can hold the nut tube (end), but as shown in Figure 8, each strip ends bends into a small ball shape on the back side of Wf41, and as a result, the screw (
When a force is applied in the direction that 6) is pulled out, each strip 04) easily bends as shown by the imaginary line in the same figure, and as a result, the strip 041 separates from the back of the wrinkle (4). The nut cylinder (10i) wobbles in the front and back direction inside the wall hole (7), which means that it cannot be expected to have sufficient holding force against the thin wall, and of course it will not clump into a small clump against the soft and thin NICK. Since only a part of the strip (14) bits into the wall (41), the wall of the bited part is deformed in the same way as in the conventional example described above.
A sufficient effect cannot be obtained.

The present inventor has discovered that each strip 04) is wrinkled +
It was discovered that the small bends in the shape of a dumpling on the 4111 plane were the cause of the inability to exert sufficient holding force against the soft thin lN41, and the band was able to firmly engage the thin wall, especially the soft thin lN41. The present invention discloses a strip that has been improved to have a dandelion shape so that it can be bent in the shape of a strip.

The present invention has been made in view of the above points, and its main purpose is to be able to securely fix it to any hard or soft wall such as a cosiclete wall or a light IL1 foamed cosiclete wall, and to be able to securely fix it to a thin wall, especially a thin wall. The object of the present invention is to provide a nut cylinder that can securely hold even a soft thin wall and firmly support a screw screwed into the wall. The embodiments of each bridge that achieve this effect are shown in the figures below. The following will be described based on examples. As shown in the figure below, the front cylinder (11), the intermediate cylinder (+4 and the rear cylinder) are basically continuous on the same axis. The intermediate part I is divided into a plurality of strip parts I arranged along the circumferential direction, and the front cylinder As the long screw (・) like a single wood screw into which the tip is screwed is tightened within 0 days of the cylinder, the rear cylinder (l) is drawn towards the front. , a longitudinal compressive force acts on the intermediate 11i01, as a result of which each strip II (In) expands radially outwards independently of each other. It is divided into front and rear parts by the starting part 05), and when the intermediate cylinder receives the above-mentioned compressive force in the longitudinal direction, the strip and (14
1 begins to protrude radially outward. In Figures 9 to 14, the intermediate cylinder 0:1 is divided into four strips NHK arranged in the circumferential direction by four slits +31 arranged in the circumferential direction and running in the elongated direction, and two strips NHK arranged in the circumferential direction are separated. An embodiment is disclosed in which two strips are cut at the center in the longitudinal direction and this cut portion is used as a 05) bending start point. Due to this structure, the compressive force in the longitudinal direction due to the tightening of the above-mentioned screws is applied to the two intermediate wheels.
It independently protrudes outward in the radial direction, and the front and rear nills (14a) (14
b) In each K-divided strip part I, each piece (14 m) begins to bend @ts (starts to protrude outward from one end of the front and back opposite to 151. The embodiment shown in FIGS. 15 to 20 , the intermediate cylinder O3 is divided into four thin bands (16) K arranged along the circumferential direction and running in the pitcher direction; A structure is disclosed in which the center part in the longitudinal direction of piece 1t (n+ is cut to form a bending start part o) similar to the above embodiment, and when the compressive force in the pitcher direction is applied to the intermediate cylinder I, each The thin band C16) is broken and each band part (1
41 independently protrudes outward in the radial direction in the same manner as in the above embodiment, and begins to bend Since the nut tube flash is formed into a continuous thin-walled band, the mold structure is simpler than when the nut tube is formed by dividing each strip portion I with a slit fa+.The above-mentioned In the example of two nuts, when a plurality of grooves aη are lined up along the circumferential direction on the outer periphery of each of the two nuts, and a nut cylinder is inserted into the wall hole drilled by Each lip Oη bites into the inner periphery of the wall hole and positions the nut Ryogoku at a predetermined position.In addition, the inner diameter of the intermediate cylinder α in each embodiment,
That is, as shown in FIGS. 12 to 14 and 1.8 to 20, the size of the circle passing through the apex of each strip portion D4 having a fan-shaped cross section is
It is smaller than the inner diameter of I O'4, and there is
! ! The inner surface of the front end of the intermediate cylinder 01 that follows the intermediate cylinder 01 has a curved surface, and the inner diameter of the intermediate cylinder 01 in this part gradually decreases toward the rear. The inner diameter of the front cylinder (11) is set larger than the diameter of the screw (6) used, and the inner diameter of the rear cylinder ring is set to a size that allows it to be screwed into the screw (I+), as shown in Fig. 21. When inserting the screw (6) into the nut Ryogoku, the screw (6) hits the surface of the above-mentioned Q, pushing each strip 5 (I4I) outward and expanding it, causing the tip of the screw to It is screwed onto the inner surface of the rear cylinder (1'4).Next, the case where the Nut Ryogoku of each of the above embodiments is applied to various types of walls will be explained.Figure 422 shows ordinary reinforced Cosicrete I! as a hard wall.
