Japanese Unexamined Patent Publication No. 09-004093 (pages 3 and 4; FIGS. 1 and 2) Japanese Unexamined Patent Publication No. 09-004094 (pages 3 and 4; FIGS. 2 and 3)

However, in the panel for a boundary wall disclosed in Patent Document 1 and Patent Document 2, it is possible to play a role as a boundary wall, but a heavy equipment such as a sink for a sink on the room side. It was difficult to install.
In other words, when attaching a heavy equipment such as a sink for a sink to the boundary wall as disclosed in Patent Documents 1 and 2, it is necessary to select a location with a core material, In addition to being restricted in position, the ready-made product could not be used and the cost increased.

  An object of the present invention is to solve the above-mentioned problems, and it is possible to easily install equipment on a boundary wall configured as a panel, and for equipment installation that can be easily installed. An object of the present invention is to provide a foundation and a field wall foundation, and a field wall panel.

According to the first aspect of the present invention, there is provided a facility mounting base embedded in a boundary wall for partitioning an indoor space and serving as a base for mounting fixtures outside the boundary wall. An equipment mounting portion, and a locking member that stands up from the equipment mounting portion, and the locking member includes an equipment mounting portion joint that stands up from the equipment mounting portion, and the equipment mounting portion joint. On the free end side, provided with a locking claw formed at a predetermined angle with the facility attachment portion joint portion, the facility attachment portion joint portion is erected from the facility attachment portion, A locking claw joint portion to which the locking claw is joined, and the connection portion and the locking claw joint portion are continuous in a substantially L-shape having an obtuse angle α. And the engaging claw is connected to the connecting portion on the surface opposite to the surface facing the connecting portion of the engaging claw joint portion. It is solved by being fixed at an acute angle (180 ° -α).

Thus, the equipment mounting base according to the present invention includes the equipment mounting portion and the locking member.
The locking member includes an equipment mounting portion joint that stands up from the equipment mounting portion, and a locking claw that is formed at a predetermined angle with the equipment mounting portion joint.
As described above, since the equipment mounting portion joint and the locking claw have a predetermined angle, if a force in the direction opposite to the equipment mounting portion joint direction is applied to the locking claw, Due to the flexibility of the claw, the locking claw bends in the direction opposite to the equipment attachment portion joint direction, and a pressing force is generated in the opposite direction by the restoring force.
In addition, since the equipment mounting part joint stands up from the equipment mounting part, if a force in the direction opposite to the side where the locking claw is disposed is applied to the equipment mounting part joint, the equipment mounting part joint Due to the flexibility of the part, it bends in the same direction, and a restoring force causes a pressing force in the opposite direction.
Therefore, when the object to be locked is press-fitted into the inner corner formed between the locking claw and the equipment mounting part joint, these pressing forces become an action force for locking the locking claw. The base for equipment installation is locked to the object by the locking claw.
Therefore, the equipment mounting base can be temporarily fixed easily by locking the locking claw to any of the members constituting the boundary wall.
In addition, the plate-like equipment mounting portion is not only a substantially flat plate-like member, but also has any shape such as a plurality of protrusions formed on the surface to improve the strength. Also good.

When the substantially T-shaped leg portion of the locking claw is configured to be flexible, a vertical frame is press-fitted into the inner corner formed by the locking claw and the connecting portion. This is preferable because the locking member can be easily locked to the vertical frame.
As above-mentioned, a latching claw and an installation attachment part junction part press a latching target object with the pressing force resulting from the restoring force produced by the flexibility. With this pressing force, the locking member is securely locked to the locking object.

Further, at this time, if a protruding edge standing substantially vertically is formed on at least one side of the facility mounting portion, the strength of the facility mounting portion (strength in the vertical direction of the facility mounting portion) ) Is preferable.
When installing equipment to the equipment mounting section, fixing members such as screws and bolts are driven through the surface material in the vertical direction of the equipment mounting section, so a large force is applied in the vertical direction of the equipment mounting section. It will be.
Therefore, if the protrusion is formed and the strength of the equipment mounting portion in the vertical direction is increased, the material forming the equipment mounting portion can be thinned. Therefore, the manufacturing cost of the equipment mounting base can be suppressed.

Furthermore, at this time, when the locking claw is locked to at least one corner of the steel frame forming a substantially rectangular frame that forms the framework of the boundary wall, the locking claw is easily locked. This is preferable because it can be securely locked to the frame of the boundary wall.
As described above, the locking claw and the equipment attachment portion joint are locked to the locking object by the pressing force resulting from the restoring force due to the flexibility.
For this reason, the base for equipment attachment can be easily latched by press-fitting the corner of the steel frame into the inner corner formed by the engaging claw and the equipment attachment portion joint.

Further, at this time, at least one of the locking claws is provided on each side of the equipment mounting base facing each other, and the equipment mounting base is in a state of bridging a pair of opposing steel frames. It is preferable to dispose the locking claw at the corner portion.
Such a configuration is preferable because the facility mounting base can be easily mounted on a necessary portion of the frame body which is a framework of the field wall panel.
In addition, since the locking claws are locked to the corners of the steel frame that forms the framework on the boundary wall, the installation position of the equipment mounting base is not limited, and the equipment mounting base can be easily placed at the required position. Can be arranged.

Furthermore, the field wall foundation according to the present invention includes at least the substantially rectangular frame that serves as a framework of the field wall for partitioning the indoor space, and the facility mounting foundation according to the present invention.

The base for equipment installation according to the present invention is a substantially flat plate-like member, and is embedded in the field wall panel in a state of being attached to a frame which is a framework of the field wall panel.
For this reason, this base for mounting equipment can be used as a basis for mounting equipment such as a sink for a sink.
Usually, the boundary wall panel is configured by attaching a surface material such as a gypsum board to a frame that is a framework.
For this reason, in order to attach a heavy equipment such as a sink for a sink to the wall, there is a limitation that it can be attached only to a steel frame portion as a framework.
However, if the equipment mounting base according to the present invention is used, the equipment mounting base serves as a basis for mounting the equipment, so that even if the steel frame that is the framework is not located, the weight of the equipment mounting base Large equipment can be installed.

Moreover, the base for equipment attachment which concerns on this invention has an equipment attachment part and a latching member, and is comprised.

In the present embodiment, the head of the locking claw 12c is welded to the back surface of the locking claw joint 12e, but the fixing method of the locking claw 12c is not limited to this.
For example, the leg portion of the locking claw 12c may be formed by notching and bending the locking claw 12c.

Thus, when the bending angle of the locking claw joint portion 12e is α, the angle β formed by the leg portion of the locking claw 12c and the vertical frame locking portion 12b (main body) is (180 ° -α).
For this reason, elasticity (elasticity due to flexibility) is generated in the leg portion of the locking claw 12c in the direction A in FIG. 4 and in the opposite direction.
Moreover, since the vertical frame latching | locking part 12b is bent continuously from the base steel plate junction part 12a, this vertical frame latching | locking part 12b has the A direction of FIG. Elasticity in the opposite direction (elasticity due to flexibility) occurs.

The base 3 for equipment attachment is obtained by locking the locking member 12 to the corner 1a of the vertical frame 1 with the sides on which the ribs 11a and 11a are formed facing each other in the vertical direction. Temporarily secured to W.

Next, the surface wall P is attached to one side of the outer frame W (the side on which the facility mounting base 3 is disposed) to form the field wall panel T.
The surface material P is attached to the outer frame W by driving a screw, a screw or the like from the outside. At this time, the equipment mounting base 3 is also permanently fixed by the screw, the screw or the like.

Thus, since the equipment mounting base 3 is temporarily fixed by the locking members 12, 12, 12, and 12, it is not necessary for the worker to hold down the equipment mounting base 3 until the fixing.
For this reason, the assembly work of the field wall panel T becomes easy.
As the surface material P, for example, a known surface material such as a gypsum board is used.

FIG. 7 shows an example of another embodiment of the locking member 12.
The 2nd latching member 112 is comprised by the 2nd base steel plate junction part 112a, the 2nd vertical frame latching | locking part 112b, and the 2nd latching claw 112c.
The second base steel plate joining portion 112a and the second vertical frame locking portion 112b according to the present embodiment are formed by bending a substantially rectangular steel plate into a substantially L shape.
In addition, the side with a small area from a bending point is made into the 2nd base steel plate junction part 112a, and the side with a large area is made into the 2nd vertical frame latching | locking part 112b.

An angle formed by the second locking claws 112c (the side where the second base steel plate joint 112a is formed) and the second vertical frame locking portion 112b is defined as γ.

Since it is formed in this way, the angle δ formed by the second vertical frame locking portion 112b and the second locking claw 112c (the side where the second base steel plate joining portion 112a is not formed) is (180 ° − γ).
For this reason, elasticity (elasticity due to flexibility) occurs in the leg direction of the second locking claw 112c in the direction B and the opposite direction in FIG.
Moreover, since the 2nd vertical frame latching | locking part 112b is bent continuously from the 2nd foundation steel plate junction part 112a, this 2nd longitudinal frame latching | locking part 112b is with respect to the 2nd foundation steel plate junction 112a. Thus, elasticity in the direction B and the opposite direction in FIG.

  For this reason, the corner | angular part of the vertical frame 1 is set in the inner corner part which the 2nd latching claw 112c (the side in which the 2nd base steel plate junction part 112a is not formed) and the 2nd vertical frame latching | locking part 112b (main body) form. Is inserted into the second vertical frame locking portion 112b (restoring force generated in the direction B in FIG. 7) and the restoring force of the second locking claw 112c (in the direction opposite to the direction B in FIG. 7). The vertical frame 1 is pressed by the restoring force generated toward The second locking member 112 is locked to the vertical frame 1 by this pressing force.

As described above, the locking member 12 (second locking member 112) provided on the equipment mounting base 3 is locked to the corner portions 1 a and 1 a of the vertical frames 1, 1, thereby providing the equipment mounting base. 3 can be temporarily fixed to the outer frame W.
For this reason, equipment such as a sink for a washstand can be attached to the base 3 for equipment installation, and construction is also facilitated.
