Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail cap unit used in places where handrails are installed in buildings, bridges, roads and the like.

[0002]

2. Description of the Related Art When a balustrade is attached to a handrail such as a balustrade installed on a balcony, a building rooftop, or the like, the cap is fixed to a parapet as shown in FIG. The handrail is supported by a bolt (not shown) held by a bolt held on a base also fixed to the parapet.

In FIG. 11, when the top end surface of the parapet has irregularities, it is necessary to adjust the height of the fixed position of each base and the holder in order to lay the handrail horizontally. In that case, the height adjustment of the same parts can be done by making a scoring groove through which the water thread passes in the same place on the surface, but even if the scribing groove is inserted in the base and holder with different shapes, the water thread will simultaneously Because they do not pass, it is not possible to adjust the height of both at the same time. There is also a method of forming a mark such as a protrusion having the same shape at the same height of both the base and the holder, but this is not easy because the body itself is not the same shape.

[0004] The problem of difficulty in height adjustment due to the different shapes of parts can be solved by integrating the base into the holder as shown in FIG. Since the support of the handrail is not always provided upright, the base of the base-integrated holder fixed at a position where the support is not provided upright is wasteful and uneconomical. The diameter of the bolt held by the base is made different depending on the size (diameter) of the support, but when the base is integrated with the holder, the entire base-integrated holder must be replaced. It is necessary to prepare a base integrated holder for each diameter, and the number of parts to be prepared increases.

[0005] As shown in FIG. 11, a hole for inserting the bolt is formed at a position corresponding to the bolt held on the base of the cap, a sleeve is arranged around the bolt having the cap inserted, and an upper end of the bolt is provided. Since the nut that locks to the sleeve is tightened, the cap is restrained by the base while being sandwiched between the base and the sleeve. The long-length caps tend to expand and contract due to temperature changes. However, when the caps are restrained by the base fixed to the parapet, thermal stress is generated in the caps between adjacent bases, causing distortion. If the insertion hole drilled in the Kasagi is a long hole, it can expand and contract when the strain exceeds a certain amount, but since it is compressed by the base and sleeve, expansion and contraction occurs rapidly, Friction noise is generated.

In view of the above background, the present invention proposes a heddle unit which facilitates height adjustment of the base and the holder, enables the base to be disposed at the standing position of the column, and eliminates distortion and frictional noise caused by temperature change of the heddle. Is what you do.

[0007]

According to a first aspect of the present invention, a base for supporting a support of a handrail is removably combined with a holder for holding a cap, so that the holder for the top end surface of a member to be mounted, such as a parapet, on which the cap is mounted. And the height adjustment of the base is simplified, and the base can be arranged only at the required position where the support is erected.

Since the base is detachable from the holder, if the base is combined with the holder with the height of the holder adjusted, the height of the base is adjusted as a result. , You only need to adjust the height of the holder,
There is no need to separately adjust the height of the base, and the height adjustment operation is simplified. In addition, since the base is detachable from the holder, the base only needs to be combined with the holder that is fixed to the place where the support is erected, and the base is not combined with the holder where the support is not erected. As a result, there is no waste of parts, and it is more economical than the base integrated holder. Specifically, the base is attached to the holder when the handrail is erected on the kasagi as described in claim 2, and is not attached to the holder when the handrail is not erected on the kasagi,
It is selectively used depending on the presence or absence of handrails.

In Japanese Utility Model Publication No. 4-21393, the base is detachable from the holder. However, a nut having a female screw for screwing a bolt holding the support column is formed on the upper surface of the base. In addition, it is not possible to place a cap on the base without bolts, and the base cannot be selectively used in the standing position of the support. According to the third aspect, by attaching a shaft member such as a bolt for holding the column detachably to the base, only the shaft member can be replaced while the base is combined with the holder, and with the difference in the dimensions of the column, It is easy to cope with a case where the dimensions of the shaft portion of the shaft member are different.

In this case, when changing the dimensions of the shaft member, the base may be left in the holder and only the shaft member may be separated from the base and replaced. It is not always necessary to replace the entire base. The types of parts to be prepared are reduced, and a rational configuration is achieved. According to claim 4, when the shaft member holding the support is attached to the base, the base is combined with the holder so as to be relatively movable in the longitudinal direction of the cap, and the shaft member is penetrated through the cap, whereby the shaft member is By holding the lower end to the base and connecting the upper end to the sleeve arranged around the shaft member on the cap, the integrity of the base and the cap is ensured, and the generation of friction noise between the holder and the expansion and contraction of the cap is reduced. To prevent. In this case, it does not matter whether the shaft member is detachable from the base or fixed to the base.

The lower end of the shaft member is held by the base, and the upper end of the shaft member that penetrates the cap is connected to the sleeve around it, so that the cap is sandwiched between the base and the sleeve that hold the shaft member and is integrated with the base. However, since the base is movable relative to the holder in the length direction of the cap, the expansion and contraction in the length direction of the cap is not restricted by the holder. Relative movement,
Expansion and contraction occur freely. As a result, no thermal stress is generated in the cap, and no distortion occurs.

When the cap is going to expand and contract, the cap is not distorted because it is not distorted, and the generation of friction noise between the base and the holder and between the cap and the holder is prevented. You.

The type of the fixing material 8 is determined by the structure of the member 5 to be mounted. In the case of concrete, mortar, ALC plate or the like, an anchor such as a hole-in anchor or a chemical anchor as shown in FIG. In the case of a bolt or the like made of wood, a coach screw or the like as shown in FIGS. 6 to 10 is used as the fixing material 8. The cap 2 is dropped from above the holder 3 so as to surround the holder 3 as shown in FIG. 3, and is formed at a position corresponding to the holding portions 3a, 3a of the holder 3 on both sides in the thickness direction of the mounted member 5. The engaged portions 2a, 2a are elastically engaged with the holding portions 3a, 3a, thereby maintaining the state held by the holder 3. FIG. 3 shows a cross section taken along the line xx in FIG.

When the engaging portions 2a, 2a are engaged with the holding portions 3a, 3a between the lower surface of the cap 2 and the upper surface of the holder 3,
The spacer 9 is interposed as necessary to suppress the generation of frictional force at the time of expansion and contraction of the coping 2 due to the contact between the holder 3 and the cap 2, and to enhance the effect of the engagement between the engaging portion 2a and the holding portion 3a. A clearance is secured between the cap 2 and the holder 3. The spacer 9 is made of a material having a small coefficient of friction between the cap 2 and the holder 3 or a material having a high deformability.

As shown in FIG. 1, the mounting portion 3b of the holder 3 is open in the sliding direction so that the base 4 can be attached to and detached from the holder 3 by sliding. Locked portions 3c, 3c are formed to hold the mounting state of 4 and prevent the upper portion 4 from slipping out. Locked part 3
The guides c and 3c serve as guides when the base 4 is detachably operated by sliding.

In the drawing, in order to freely expand and contract the cap 2 due to a temperature change, the mounting portion 3b is formed so as to be continuous in the length direction of the cap 2 and open at least one end in that direction. The holder 3 is detachable in the length direction of the cap 2 and is relatively movable with respect to the holder 3. However, when the influence of expansion and contraction does not matter, such as dividing the cap 2 into fixed length units, the mounting portion 3b May be opened in the width direction of the coping 2.

The base 4 has a shape that fits in the mounting portion 3b of the holder 3 and is engaged with the locked portions 3c, 3c of the holder 3 upwardly or vertically on both sides in the thickness direction of the mounted member 5. Part 4a,
4a is formed. The base 4 is screwed to the upper end of the shaft member 10 as will be described later, and tries to float up from the holder 3 by the tightness of the nut 12 that sandwiches the sleeve 11 between the shaft member 2 and the base member 4. The portion 4a only needs to have a relationship in which the locking portion 4a is locked at least upward with the locked portion 3c.

The base 4 has a locking portion 4a which is a locked portion of the holder 3.
By being slid in the horizontal direction while being guided by 3c, it is arranged on the bottom surface of the mounting part 3b, and the mounting state is maintained by the locking parts 4a, 4a locking to the locked parts 3c, 3c. When the fixing portion 10a is formed at the lower end of the shaft member 10 such as a bolt as shown in FIG. 1, FIG. 3, etc., the fixing portion 10a is inserted into the base 4 at a position corresponding to the standing position of the column 7. A storage section 4b is formed to lock the fixing section 10a upward. Storage section

When the upper end of the storage portion 4b and one end in the sliding direction are opened, the base 4 is held by the holder when the size of the shaft portion 10b of the shaft member 10 is changed due to the difference in the size (diameter) of the support column 7. It is possible to replace only the shaft member 10 while holding the shaft member 3. The shaft member 10 is composed of two parts, a fixing portion 10a and a shaft portion 10b that penetrates through the coping 2 and protrudes upward. When only the shaft member 10 is replaced while the base 4 is held by the holder 3, The shapes and dimensions of the fixing portions 10a of the plurality of shaft members 10 are unified, and only the diameter of the shaft portion 10b is different.

When a bolt is used for the shaft member 10, the head becomes the fixing portion 10a. The fixing portion 10a is also formed by joining a shaped steel such as a plate to one end of a bolt having only the shaft portion 10b. The height of the upper end of the shaft member 10 is adjusted by interposing the liner 13 above the fixing section 10a in the storage section 4b. At the position of the holder 3 where the base 4 is mounted, of the entire holder 3, the cap 2 is dropped onto the holder 3 with the shaft member 10 held by the base 4. As shown in FIG. 1, the shaft portion of the shaft member 10
An insertion hole 2b through which 10b is inserted is opened. As described above, when the base 4 is made relatively movable in the length direction of the coping 2 with respect to the holder 3, the coping 2 can freely expand and contract in the length direction with respect to the holder 3 together with the base 4 and the shaft member 10. The insertion hole 2b does not need to be a long hole.

After setting the cap 2 on the base 4, the sleeve 11 through which the shaft 10 b of the shaft member 10 is inserted is dropped from the cap 2, and the sleeve 11 is cut into the thread cut at the upper end of the shaft 10 b.
A nut 12 locked to 11 is tightened. A sealer 14 is sandwiched between the lower end of the sleeve 11 and the upper surface of the cap 2 at the position of the insertion hole 2b of the cap 2 to ensure watertightness. Sleeve by tightening nut 12
