Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail bracket mounting structure.

[0002]

2. Description of the Related Art Conventionally, the following method has been adopted for attaching a handrail to a wall surface of a building.

First, as shown in FIG. 3 (A), the wall surface portion 110 is constructed such that the wall surface portion 110 forms a frame body with a core material (not shown) assembled in a frame shape, and both surfaces thereof are formed. The face material 116 is fixed, and further, an interior material such as a gypsum board 112 is attached on the face material 116 of the wall surface portion 110 which is the inside of the wall of the building.

To attach the handrail 100 from the inner wall side to the wall surface portion 110 to which the gypsum board 112 is attached, the gypsum board 112 is cut out at a predetermined position of the wall surface portion 110 (that is, on the gypsum board) to which the handrail 100 is attached. Then, the base plywood 114 is embedded in the gypsum board 112, fixed by adhesive nailing, etc., and putty treatment 118 or the like is applied to the joint boundary area. Further, a receiving piece 92, a supporting piece 94, etc. are mounted on the base plywood 114, and the receiving piece 9
2. The supporting piece 94 is covered with the handrail bracket 90, and the supporting piece 94 and the handrail bracket 90 are attached and fixed from below by the screw 96 or the like, whereby the handrail 100 and the wall surface portion 110 are attached. The handrail bracket 90 and the handrail 1
00 is fixed by screws or the like (not shown).

However, mounting the handrail in this way is not only a troublesome work, but also because of the large number of members, cost down is not achieved and the construction work is simplified. Does not go along.

Further, as shown in FIG. 3 (B), a hole for screw insertion is preliminarily formed in the handrail bracket 120, and a screw 112 or the like is inserted into the hole, whereby the gypsum board 1
It is conceivable to mount and fix the handrail bracket 120 directly from above 34. In addition, in order to secure the strength of the wall surface portion, plywood 132 is provided in advance on the back surface of the plaster board 134 instead of the face material.

However, in such a configuration, FIG.
As indicated by the chain double-dashed line Z, a bending moment due to a load applied to the upper end of the handrail bracket 120 on the side opposite to the mounting side is applied to the mounting surface of the gypsum board 134, and the gypsum board 134 is a relatively soft material. Therefore, the handrail bracket 120 may be inclined.

In particular, when the handrail 100 having a relatively large weight is attached to the handrail bracket 120, the weight of the handrail 100 has a great influence. Furthermore, this is all the more true when a hand is placed on the handrail and a large load is applied.

When tilted, the handrail bracket 12
Since the lower end in the joining direction of 0 is embedded in the gypsum board 134, the handrail 100 itself is slanted so that it does not look good in appearance and cannot be used as a handrail.
It is conceivable that there will be a problem that 34 is crushed or damaged around the attachment portion as a center.

By the way, the applicant of the present invention has previously searched the prior art with the search formula: E04F11 / 18 * (reinforcement + enhancement + load) by the prior art search (Patris) of the Japan Patent Information Organization (JAPIO), and obtained a patent. 32 cases, utility model 97
The results of the survey were obtained. From this result, it was not possible to find a technique for solving the above problems.

The present invention has been made in order to solve the above-mentioned problems of the prior art. The object of the present invention is to prevent inclination due to a bending moment and maintain a good state even after mounting. It is to provide a mounting structure of a handrail bracket that can be performed.

Another object of the present invention is to provide a mounting structure for a handrail bracket which simplifies the mounting work.

[0013]

Can be supported and fixed.

Further, unlike the conventional case, the handrail bracket can be fixed to the wall surface without scraping or crushing the face material in the vicinity of the mounting position of the handrail bracket, so that the handrail bracket can be mounted well. The appearance after mounting is good and the mounting work can be simplified.

Further, even if the conventional handrail bracket is not specially processed, only the load receiving member needs to be provided, and the number of parts for mounting is small, so that the cost can be reduced.

[0020]

Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 FIG. 1 shows a mounting structure and its constituent elements when a handrail bracket 10 according to this embodiment is used on a wall surface of a building.
Will be explained.

FIG. 1 is a sectional view showing a mounting structure when a handrail bracket 10 according to this embodiment is used on a wall surface of a building.

As shown in FIG. 1, the handrail bracket 10 and the wall panel 40 are listed when the constituent elements of the mounting structure of this embodiment are listed. Hereinafter, each of the above constituent elements will be sequentially described.

First, the wall panel 40 to which the handrail bracket 10 is attached will be described, and the overall structure will be described. Then, the handrail bracket 10 will be described in detail.

As shown in FIG. 1, the wall panel 40 has a frame body composed of a core material 44 assembled in a rectangular frame shape and an auxiliary core material (not shown) provided between two opposing sides of the core material 44. Configure and
A face material 46 is fixed to both surfaces of the same wall panel 40.
A gypsum board 48 is attached as an interior material on the surface material 46, which is one surface on the inner wall side.

Although not shown, the face material may not be attached to one surface on the inner wall side of the frame body, and the gypsum board may be attached directly to the frame body. In this case, since the gypsum board also functions as a face material for maintaining the rigidity of the frame body, the material of the portion corresponding to the face material may be a decorative gypsum board, plywood or the like. Therefore, in the following description, when it is described as “on the surface of the gypsum board 48”, the face material 46 is attached to the frame body, and when the gypsum board 48 is attached from above the face material 46, the gypsum board 48 This means a case where the handrail bracket 10 is mounted and fixed from above. Also, "face material 46 or gypsum board 4
In addition to the above meaning, when a surface material (not shown) is directly attached to the frame and the portion corresponding to the surface material is plywood, gypsum board, etc., It is meant to include the case where the handrail bracket 10 is directly mounted and fixed on the face material.

Incidentally, the gypsum board 48 has a function as an interior material, and the material is preferably semi-incombustible and hard hemihydrate gypsum (CaSO ₄ .1 / 2H ₂ O) or the like, for example, semi-funtenten. (Product name) and the like. Further, glass gypsum, rock wool, pulp, perlite, and stones may be used as the plaster. Furthermore, the surface is processed by printing, scoring, etc. on the base paper for gypsum board, which has excellent discoloration resistance, stain resistance, and scratch resistance, or the surface is processed by overlay, embossing, painting, etc. Has been given a makeup finish.

Next, the structure of the handrail bracket 10 will be described with reference to FIG.

The handrail bracket 10 is a rigid member having a cross section as shown in FIG. 1, and includes a supporting portion 12 and a load receiving member 2.
0 and a handrail portion 30 fixed to the support portion 12. In the present embodiment, the support portion 12
The load receiving member 20 and the load receiving member 20 are integrated.

The support portion 12 has a function of supporting the handrail portion 30, and is formed so as to be parallel to the standing direction of the wall panel 40 and upward. Further, a rigid member is preferable, and examples of the material thereof include zinc die casting.

The load receiving member 20 is a wedge-shaped member having a substantially wedge-shaped lateral cross section, and is integrally formed with the supporting portion 12. Further, the wedge-shaped member is the handrail bracket 1
It is a protruding end formed by protruding from the lower portion of the mounting portion 12 on the mounting side toward the mounting direction. This is because the handrail bracket 10 constitutes the core member 46 that constitutes one surface of the wall panel 40.
Alternatively, when it is mounted on the surface of the gypsum board 48, it is easier to embed the wall panel 40 from the surface of the gypsum board 48 toward the inside of the wall panel 40.

The load receiving member 20 is attached to the wall panel 40.
The core material 44 inside the wall panel 40 should be installed beforehand.
Alternatively, a mark or the like is provided on the surface of the face material 46 or the gypsum board 48 having an auxiliary core material (not shown), and the load receiving member 20 is directed from the surface of the face material 46 or the gypsum board 48 toward the core material 44.
Embed Furthermore, the length (from the surface of the gypsum board 48 to the core material 4 is set in advance so that the tip portion of the wedge-shaped member, which is the wedge-shaped load receiving member 20, contacts the core material 44.
(Length up to the mounting surface of 4) is set. This allows
The bending moment applied to the support portion 12 can be transmitted to the core material 44 to prevent the gypsum board 48 from being deformed (the reason will be described later).

The handrail portion 30 is fixed to the projecting end of the support portion 12 of the handrail bracket 10 by a screw or the like (not shown). In this embodiment, it is formed of a member having a circular cross section as shown in FIG. Has been done.

Next, the structural characteristics of the handrail bracket 10 will be mechanically described.

In the handrail bracket 10 according to the present invention, the following three main structural characteristics can be considered.
That is, the wedge-shaped member that is the load receiving member 20 is the handrail bracket 10.
It should be provided in the lower region of the mounting side of the supporting part 12 of FIG.

The tip end of the protruding end of the wedge-shaped member that is the load receiving member 20 must be in contact with the core material 44 (in other words, the protruding length of the wedge-shaped member that is the load receiving member 20 is the gypsum board 48). The distance is not less than the sum of the plate thickness and the plate thickness of the face material 46). The load-bearing member 20, which is a wedge-shaped member, has a wedge shape and has an upwardly tapered surface in a state in which the tip is tapered in a direction orthogonal to the standing direction of the wall panel 40.

First, the reason, that is, the reason why the wedge-shaped member as the load receiving member 20 is provided in the lower region of the handrail bracket 10 on the mounting side will be described.

Here, each point and each variable are defined as follows (see also FIG. 1).

A: force point (upper end of the protrusion of the support portion 20 formed on the handrail bracket 10) B: fulcrum (protruding base end of the wedge-shaped member that is the load receiving member 20) C: point of action (wedge-shaped member that is the load receiving member 20) Member protruding end) D: _A fulcrum when a wedge-shaped member that is virtually the load receiving member 20 is provided in the upper region of the mounting side F _A : Force applied to the point A (load including the handrail 30's own weight) F _BD : Load receiving member 20 a force wedges is applied to point B when it is in the attachment-side upper region is (force F force _a due to the bending moment is transmitted to the point B when produced) F _C1: the force applied to the point C (Support reaction force generated by load F _A ) F _C2 : Vertical component of force applied to point C X: Length of vertical line dropped from point D to direction line of force F _A Y: Between point B and point D Distance: l: distance between points B and C θ: inclination angle of wedge-shaped wedge-shaped member Load F _A including the weight of the handrail bracket 10 to the projecting upper end (point A) of the support portion 12 of the bets 10 and are added.

As shown by the chain double-dashed line in FIG. 1, it is assumed that a virtually wedge-shaped member, which is the load receiving member 20, is located in the upper region of the handrail bracket 10 on the mounting side of the supporting portion 12. At this time, point A
Since the load F _A is applied to, a supporting reaction force (not shown) is generated at the tip portion of the wedge-shaped wedge-shaped member with the point D as the fulcrum. When balanced in this state (in the case of the chain double-dashed line in FIG. 1), the force F _BD as described below acts on the point B in the lower region. That is, since the moment about the point D is a constant, equal and moment around point D of the force F _A acting on the point A, the moment around point D of the force F _BD acting on the point B, X × F _A = Y × F _BD . Therefore, F _BD =
The force F _BD acting as (X / Y) F _A acts. This is because when the load F _A is applied to the point A, a force F _BD larger than the allowable stress of the gypsum board 48 is exerted, the surface of the gypsum board 48 is crushed, and the handrail bracket 10 main body has a small amount around the point D. It means that a rotating action occurs. This is a problem that occurs when the structure of the conventional handrail bracket is used.
_BD is the force transmitted by the bending moment generated by the load F _A, which is considered to be the cause of damaging the gypsum board.

On the other hand, as in this embodiment shown by the solid line in FIG. 1, the wedge-shaped member serving as the load receiving member 20 is the handrail bracket 1.
Consider the case where it is in the lower region on the mounting side of the supporting portion 12 of 0.
When balancing in this state, point B becomes a fulcrum,
The force transmitted by the bending moment generated by the load F _A is in this case generated at point C. That is, the force of bending the plaster board 48 by bending the mounting-side lower region of the support portion 12 of the handrail bracket 10 is transmitted to the wedge-shaped tip portion by the wedge-shaped member that is the load receiving member 20. Also,
At this time, in the above formula F _BD = (X / Y) F _A , since Y → 0 in the case of the mounting side lower area, if Y → 0, then F _BC
→ It becomes ∞, and it can be seen that the maximum force is applied at this point (lower end on the mounting side, point B). Therefore, if a wedge-shaped wedge-shaped member is provided at a position where this maximum force is generated, a force smaller than this maximum force is applied to the other mounting side surface,
The surface of the gypsum board 48 that abuts on the side surface of the mounting side other than the vicinity of this point (lower end of the mounting side, point B) is not damaged.

Further, in this state, conversely, the force F _DB (not shown) generated in the upper region (point D) on the mounting side acts in the direction opposite to the force F _BD , that is, in the direction opposite to the mounting side. The gypsum board 48 is not pressed by the mounting-side upper region, and the gypsum board 48 is not damaged in the mounting-side upper region.

Thus, the force (supporting reaction force in this case) is directly applied to the core material 44 of the wall panel 40 with which the wedge-shaped tip portion of the wedge-shaped member contacts without pressing the surface of the gypsum board 48.
Therefore, the problem as in the conventional example does not occur.

If the load receiving member 20 is in the upper region of the mounting side, the force F _BD that exceeds the allowable stress of the gypsum board 48 acts at the point B, and the surface of the mounted region of the gypsum board 48 is destroyed. . That is, the gypsum board 48 is crushed and damaged by the bending of the handrail bracket 10 due to the bending moment generated by the load F _A. However, by providing the load receiving member 20 as in the present embodiment in the lower region of the mounting side, and using the point B as a fulcrum, the force that should occur at that portion (point B) is applied to the tip portion (point C). It is possible to prevent the breakage of the gypsum board 48 by absorbing it by the supporting reaction force generated in. The following reason will be explained.

Now, it is assumed that the point C, which is the tip of the virtually wedge-shaped wedge-shaped member, is at a point C '(not shown) shorter than the length l. When balanced in this state, the moment around the point B is constant, so at the point C ′ (not shown) shorter than the length l, the force F _{C ′} acting on the point C ′ around the point B is the moment. And the force F _A acting on the point A is equal to the moment around the point B, and the distance between the points B and C ′ is m (where l> m), then X × F _A = m × F It becomes _{C '} .

On the other hand, as shown in FIG. 1, when the point C, which is the tip of the wedge-shaped wedge-shaped member, keeps the distance l with respect to the point B, when the points are balanced in this state, the moment around the point B is constant. Therefore, the force F _C acting on point C is point B
And moment around, equal to the moment around the point B of the force F _A acting on the point A, the _{X × F A = l × F} C.

Therefore, (X × F _A =) 1 × F _C = m × F _{C '}
Therefore, F _{C ′} / F _C = 1 / m. Where l>
Since m, F _{C '} > F _C.

[0048] Thus, the longer the wedges of wedge, the force F _C acting on the distal end portion constituting the projecting end is smaller than the short force when F _{C ',} the distal end portion, due to the load F _A It can be seen that the supporting reaction force F _C is less likely to be burdened. Further, in this manner, the tip end portion of the wedge-shaped wedge-shaped member always reaches the core material 44, so that the supporting reaction force F _C generated by the load F _A is generated in the gypsum board 48 to damage the gypsum board 48. There is no such a case, and it can be transmitted into the core material 44. This effect is the handrail bracket 1
The bending of the handrail bracket 10 due to the bending moment transmitted to the lower portion of the support portion 12 on the mounting side of the gypsum board 4
This occurs in combination with the above effect of not transmitting to the surface of No. 8.

Now, the reason will be described below. It is assumed that the wedge-shaped member, which is a load receiving member, is not a wedge-shaped member and is a plate-shaped member having one surface perpendicular to the standing direction of the wall panel 40 and having no tapered surface. Suppose there is. The supporting reaction force applied at this time point C is F (not shown). The supporting reaction force F acts in the same direction as the standing direction of the wall panel 40.

On the other hand, when the wedge-shaped member has a wedge shape, a force F _C1 equal to the force F is applied to the tapered surface. At this time, since the supporting reaction force that substantially supports the handrail bracket 10 is the vertical component F _{C2 in the} same direction as the standing direction of the wall panel 40, if the inclination angle of the wedge-shaped wedge-shaped member is θ, then F _C2 (=
F _C1 cos θ) <F _C1 force F _C2 is added.

Therefore, F (= F _C1 )> F _C2 , and the force F applied in the case of a plate shape is F> due to the wedge shape.
Is Genryoku to F _C2 become a force F _C2. Therefore, due to this reducing effect, at the point C, the load of the supporting reaction force due to the load F _A is less likely to be received. Further, not only the reduction effect of the wedge-shaped tapered surface but also the wedge shape, the wedge-shaped wedge-shaped member that is the load receiving member 20 of the handrail bracket 10 is embedded in the wall panel 40, and at the same time, the wall panel 40 side has the wedge-shaped shape. Since it can be expected that a so-called pulling effect that pulls the wedge-shaped member is generated, the handrail bracket 10 can be firmly fixed and the mounting work can be facilitated.

Further, it can be considered that the generation of the supporting reaction force having a small force in the longitudinal direction has an advantage that a force which does not exceed the maximum lateral shear stress of the core material is sufficient.

Due to the above-mentioned structural characteristics, the handrail bracket 10 of the present invention has a wedge-shaped load receiving member 20 for the bending of the lower portion of the handrail bracket 10 main body on the mounting side due to the bending moment generated by the load F _A. The wedge-shaped member prevents the wall panel 4 from being transmitted to the plasterboard 48.
Since it can be transmitted to and absorbed by the core material 44 in 0, the problem that the plaster board is crushed or damaged as in the conventional example is solved.

Next, the operation of the present embodiment, that is, the method of mounting the handrail bracket 10 will be described with reference to FIG.

A wall panel 40 provided with a core material 44 or an auxiliary core material (not shown) in advance in accordance with the mounting position of the handrail bracket 10 is erected in the building construction area.

A wedge-shaped member, which is the load receiving member 20 of the handrail bracket 10, is attached to the main body of the handrail bracket 10 on the surface of the gypsum board 48 where the core material 44 of the wall panel 40 or the auxiliary core material (not shown) is present. Insert and fix until the side end face and the surface of the gypsum board 48 come into surface contact. At this time, the wedge-shaped tip end portion of the wedge-shaped member that is the load receiving member 20 is located inside (on the side of the core material 44) from the mounting surface (end face of the surface material 46 on the contact side) of the core material 44 or the auxiliary core material (not shown). ) Until it is located.

By doing so, it is possible to prevent the inclination of the handrail bracket 10 and prevent the gypsum board 48 from being damaged by transmitting the above-described laterally applied bending moment to the core member 44.

Here, in FIG. 1, a screw or the like (not shown) as shown in FIG. 3B is attached.

Finally, the support portion 12 of the handrail bracket 10
The handrail portion 30 is attached and fixed to the upper end of the handrail by a screw or the like (not shown).

As described above, according to the present embodiment, since the wedge-shaped wedge-shaped member as the load receiving member is previously attached to the lower end of the handrail bracket 10 on the attachment side of the support portion 12,
Since it is possible to prevent the handrail bracket from sinking into the gypsum board due to the weight of the handrail as in the conventional example shown in FIG. 3C, it is possible to install the handrail bracket satisfactorily and the appearance is good after installation.

Further, the handrail bracket can be fixed to the wall surface with one touch without the need to grind the gypsum board in the vicinity of the mounting position of the handrail bracket as in the conventional case, so that the construction work can be simplified. .

Further, when the handrail is attached, the number of parts is small and the cost can be reduced. Second Embodiment Next, a second embodiment according to the present invention will be described with reference to the drawings. The members having substantially the same structure as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

The mounting structure and its constituent elements when the handrail bracket 50 according to this embodiment is used on the wall surface of a building will be described with reference to FIG.

FIG. 2 is a sectional view showing a mounting structure when the handrail bracket 50 according to this embodiment is used on the wall surface of a building.

As shown in FIG. 2, the second embodiment is different from the first embodiment in that the structure of the handrail bracket 50 is different, that is, the wedge-shaped member as the load receiving member is separated from the supporting portion of the handrail bracket. It is different in that it was done.

Therefore, except for the above members, the mounting structure of the handrail bracket is almost the same as that of the first embodiment, so the description of the common parts will be omitted and only the different members will be described.

The structure of the handrail bracket 50 will be described with reference to FIG.

The handrail bracket 50 is a rigid member having a cross section as shown in FIG.
0. In this embodiment, the support portion 52 and the load receiving member 60 are separate structures.

The support portion 52 has a function of supporting the handrail 30 and is formed so as to be parallel to the standing direction of the wall panel 40 and upward. Further, a rigid member is preferable, and examples of the material thereof include zinc die casting.

The load receiving member 60 is composed of an embedding member and has a function of being embedded from the surface of the gypsum board 48 of the wall panel 40. For example, screws, screws, nails,
A wedge-shaped driving member may be used.

When the embedding member which is the load receiving member 60 is attached to the wall panel 40, the wall panel 40 is previously prepared.
Face material 4 with inner core material 44 or auxiliary core material (not shown)
6 or a plaster board 48 is marked on the surface, and the face material 46
Alternatively, the embedding member that is the load receiving member 60 is inserted from the surface of the gypsum board 48 toward the core material 44. Further, the length of the embedding member (the length from the surface of the gypsum board 48 to the mounting surface of the core member 44) is set in advance so that the tip portion of the embedding member contacts the mounting surface of the core member 44. Keep it. Thereby, the bending moment applied to the support portion 12 can be transmitted to the core material 44, and the gypsum board 48 can be prevented from being deformed.

As in the case of the first embodiment, the handrail bracket 50 is mounted on the surface of the gypsum board 48 where the core material 44 of the wall panel 40 or the auxiliary core material (not shown) is present in the same manner as in the first embodiment. The load receiving member 60, which is an embedded member, is embedded, and the mounting-side lower region of the support portion 52 of the handrail bracket 50 is flush with the head of the embedded member and the surface of the gypsum board 48. The gypsum board 48 is brought into contact with the head and the mounting side region of the supporting portion 52 of the handrail bracket 50 is made into a plaster board 48.
The method of making it contact with the surface of is adopted. At this time, the head is embedded until the head is inside the surface of the gypsum board 48. Further, at this time, the screw tip portion of the embedding member which is the load receiving member 60 is made to bite from the end surface of the core member 44 or the auxiliary core member (not shown) on the contact side of the face member 46 to a position to be inserted therein. By doing so, it is possible to transmit the bending moment in the lateral direction to the core member 44, prevent the handrail bracket 50 from inclining, and prevent the gypsum board 48 from being damaged.

Here, in FIG. 2, a screw or the like (not shown) as shown in FIG. 3B is attached.

Finally, the support portion 52 of the handrail bracket 50
The handrail portion 30 is attached and fixed to the upper end of the handrail by a screw or the like (not shown).

The effects of the second embodiment are the same as those of the first embodiment.
The same effect can be expected. Further, since the load receiving member is composed of the embedding member while satisfying the above effects, the handrail bracket can be mounted more firmly than in the first embodiment.

The present invention is not limited to the above embodiment, but various modifications can be made within the scope of the invention. For example, referring to FIG.
Even if the structure of the prior art shown in FIG. 2 is further added, the effect of the present invention can be maintained, and such a modification is possible.

A plurality of wedge-shaped members, which are load receiving members,
They may be provided regardless of the arrangement state of columns and rows.

Further, the load receiving member may have any shape and means as long as it has a function of transmitting the load applied to the supporting portion to the core material, and various other modifications are possible. Furthermore, the handrail bracket and the handrail may have any shape and configuration as long as they have a load receiving member without having the shape and configuration as in this embodiment.

[0079]

According to each of the first to fifth aspects of the invention, since the load receiving member is attached to the handrail bracket in advance, it is fragile when the handrail bracket is attached and fixed to the face material of the wall surface portion. Even if the surface material is not suitable for supporting loads,
It is possible to prevent the handrail bracket from slipping into the face material due to the weight of the handrail part, etc., and maintain a good condition even after mounting.
The handrail to which a load is applied can be firmly supported and fixed.

Further, unlike the prior art, the handrail bracket can be fixed to the wall surface without scraping or crushing the face material in the vicinity of the mounting position of the handrail bracket, so that the handrail bracket can be mounted well. The appearance after installation is good-looking and the construction work can be simplified.
