Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a reinforcing structure for reinforcing a predetermined space in a wall or ceiling base.

(Prior art) For example, a wall space or ceiling space that bears excessive weight, such as a wall surface on which a wall-mounted cooler is installed or a ceiling surface on which lighting equipment is hung, must be compared with other wall surfaces or ceiling surfaces. It needs to be reinforced in advance.

This reinforcing means is usually formed by forming a board fixed to the front of the wall stud or the underside of the field edge with a board material having a certain degree of strength, or
Alternatively, measures can be taken such as horizontally installing steady rests between the inner wall studs and reinforcing beams between the roof edges.

However, in buildings with a fireproof structure using a steel base, combustible materials must not be exposed on the interior walls or ceilings, so other materials such as wood boards are layered on the back side of the fireproof board. In practice, this construction is difficult. In the latter case, it is not effective unless the heavy object is fixed at a steady rest or the like.

(Purpose of the present invention) In view of the above-mentioned problems, the present invention is capable of sufficiently increasing the strength of a predetermined location on a wall or ceiling using a steel base material, and uniformly reinforcing the entire reinforced space. The purpose of this invention is to provide a reinforcing structure for walls, etc. that is easy to construct.

(Structure of the invention) In order to achieve the above-mentioned object, the present invention forms recesses or protrusions along the longitudinal direction on both sides of a steel base material such as a field edge or wall stud,
A holding part having a U-shaped cross section and having locking parts on both sides of the steel base material located on both sides of the space to be reinforced on the wall or ceiling to be locked in the recess or convex part. and a supporting piece connected outwardly at right angles to at least one side end of the holding part, so that the holding part holds and engages the front surface of the steel base material. The stop portion is fixed so as to be locked in the recess or the convex portion, and the supporting piece of the reinforcing metal fitting supports the back side end portion of the reinforcing board inserted in the space to be reinforced. It is characterized by the following points.

(Embodiments) The present invention will be described in detail below based on illustrated embodiments.

FIG. 1 shows an overall perspective view of a wall reinforcing structure according to an embodiment of the present invention, and reference numerals 1 and 1 in the figure indicate wall studs erected at predetermined intervals, and are made from square steel pipes. Wide grooves 2, 2 are recessed in the longitudinal direction on both sides thereof.

3 is the wall space to be reinforced between both wall studs 1, 1, 4 is the front part 1a, 1a of both wall studs 1, 1
This is a reinforcing metal fitting that is fixed in such a way as to hold it. As shown in FIG. 2, the reinforcing metal fittings 4 are formed into a shape by bending a thin strip of steel at predetermined locations. A part located in the center of this reinforcing metal fitting 4 and having a U-shaped cross section is a holding part 5 that holds the front part 1a of the wall stud 1, and its side plates 5
a is a reinforcing board 8 interposed in the reinforcing wall space 3;
It has a length corresponding to the thickness of the holding part, and has an inner locking claw 6 formed by cutting and raising the plate surface toward the holding part top plate. This inner locking pawl 6 is formed in such a length that its tip is locked in the groove 2 of the wall stud 1 when the holding portion 5 is held against the front surface 1a of the wall stud 1. There is. The supporting pieces 7, 7 integrally connected outward at right angles from the ends of the side plates 5a, 5a of the holding part 5 have a length sufficient to support the back side of both side ends of the reinforcing board 8. It has a certain quality. Reinforcement board 8
A wide variety of plate materials such as wooden plates and iron plates can be used.

During construction, first, install the left and right wall studs 1, 1.
When the reinforcing metal fittings 4 are fitted to the upper and lower ends of the wall studs 1, respectively, so that the holding parts 5 hold the front parts 1a of the wall studs 1, 1, these locking claws 6 are temporarily attached to the side surfaces of the wall studs 1. After being pushed and bent outward, it elastically returns to the groove 2 and is locked to the falling wall of the groove 2, and the reinforcing metal fitting 4 is firmly fixed at the corresponding position in the length direction of the wall stud 1 ( Figures 3 and 4
(see figure). Of course, when fixing the reinforcing metal fitting 4, screws may be driven into the top plate of the holding part 5, etc., as shown in FIG.

Next, the reinforcement space 3 between both wall studs 1, 1
Then, a plurality of reinforcing plates 8 having a surface area that fills the space 3 are stacked and interposed. This reinforcing plate material 8 is the side plate 5 of the holding part 5 of the reinforcing metal fitting 4.
The number of sheets corresponding to the thickness corresponding to the length a is stored, and the back surface of the side end is abutted against the support piece 7 of the reinforcing metal fitting 4 and supported. Interposed reinforcing plate material 8
is fixed between the wall studs 1, 1 by driving screws from the surface toward the support piece 7.

Finally, the wall board is nailed to the front of the wall stud 1 and fixed in the same manner as the other parts of the wall.

The reinforced wall constructed in this way has a reinforcing plate material 8 interposed inside, and this plate material 8 is connected to the wall studs 1, 1 via the reinforcing metal fittings 4, so that no part of the surface of the wall board It can withstand the weight of a heavy object even if it is fixed in place.

Then, if the length of the side plate 5a of the holding part 5 is adjusted according to the weight of the object fixed to the wall surface, etc.,
The number of reinforcing plates 8 supported by this can be adjusted,
A wall body with desired strength can be easily constructed. Of course, since a fire-resistant wall board is used for the innermost portion of the wall made of steel wall studs, no problem arises in terms of fire-resistant structure.

In addition, it is possible to simply fix a wall board to the wall space 3 adjacent to the wall studs 1, 1 to which the reinforcing metal fittings 4 are attached, but if this portion is also to be reinforced, it is sufficient to use the other support piece 7 to insert an appropriate number of similar board materials.

FIG. 5 shows reinforcing metal fittings 14 and wall studs 11 used in a reinforcing structure according to another embodiment of the present invention. Tsute ridge 1
2, and the reinforcing metal fitting 14 is fixed to the wall stud 11 by locking the locking recesses 16 formed on the inner surfaces of both side plates of the holding part of the reinforcing metal fitting 14 to this protrusion 12. This is the same in that the reinforcing board is interposed in the supporting piece 17 of the reinforcing metal fitting 14 in a laminated state.

In addition, in the embodiment shown in FIG. 6, grooves 22 having narrow arcuate cross-sections are formed along the longitudinal direction of the stud body on both sides of the wall stud 21 made of a square pipe, while reinforcing metal fittings A protrusion 26 is formed on the inner surface of both side plates of the holding portion 24 and is engaged with the groove 22 by using a bent portion with the support piece 27. The reinforcing metal fittings 2 are assembled by locking the protrusions 26 in the grooves 22.
4 to the wall stud 21 is the same as in each of the above embodiments.

In both embodiments, the locking portions 16, 26 of the reinforcing fittings 14, 24 and the reinforcing fittings 14, 24 themselves can be manufactured more easily than in the embodiments described above.

In any of the embodiments described above, the supporting pieces connected to the holding part of the reinforcing metal fitting are provided on both sides of the holding part, but they may be provided only on one side. In this case, it goes without saying that the support piece may be positioned on the side of the wall to be reinforced and fixed to the front surface of the wall stud.

In addition, if it is necessary to reinforce a part of the ceiling surface, although not shown, place the holding part of this metal fitting on the edge of the field located at the reinforcement point, and reinforce it in the same way as in the case of wall reinforcement described above. Simply load the board and secure the fireproof ceiling board to the surface.

(Effects) As described above, according to the present invention, a recess or protrusion formed on both sides of a steel base material such as a wall stud or a field edge is provided on both sides of the holding part of the reinforcing metal fitting. The reinforcing metal fittings are fixed to the base material by locking the locking parts, and the back side of the end of the reinforcing board inserted in the reinforcing space is supported by the supporting pieces extending to both ends of the reinforcing metal fittings. As a result, the reinforcing space between the left and right steel base materials is completely filled with reinforcing boards, which are then fixed to the steel base materials via reinforcing metal fittings, resulting in a fire-resistant wall surface. Alternatively, the strength of the ceiling surface can be sufficiently increased, and heavy objects can be fixed to arbitrary locations on the reinforced wall surface or ceiling surface.

Further, according to the present invention, the holding part of the reinforcing metal fitting can hold the front part of the steel base material within a desired range, whether shallow or wide, so the number of reinforcing boards to be inserted can be controlled by this. This makes it possible to construct walls or ceilings with desired strength.

Furthermore, according to the present invention, the reinforcing metal fittings are fixed by locking the locking parts provided on the holding parts of the reinforcing metal fittings into the recesses or protrusions on both sides of the steel base material. This allows for easy reinforcing of seeds.
