Description

[Detailed explanation of the idea] The present invention relates to a lath stopper for studs of building materials.

With the recent spread of high-rise buildings, building materials are required to have stronger fire resistance for disaster prevention purposes, and many raspods are now used for wall finishing. The lath was attached to the stud by clamping the lath with flexible ears.

However, according to the configuration of the prior art, it is first necessary to make a cut in the expensive stud, but this cut can be made integrally when the stud with a lip groove cross section is roll-formed from the plate material. As a result, processing operations separate from the forming operations are eliminated, which not only reduces the productivity of the studs but also increases the selling price of the studs.

In addition, conventional studs were transported to the site with the ears cut in the factory in an erect state, but during transportation, the erect ears were crushed by collisions between the studs, and the ears were re-cut at the site. I had to carry out correction work to make it stand up.

Furthermore, if there is a design change during the construction stage that makes it unnecessary to use the ears, the user is forced to correct the erect ears by making them lie down.

In order to solve these various drawbacks, the present invention aims to easily and reliably attach a lath to a stud without requiring cutting by using a fastener that can be easily formed.

The configuration of the present invention will be explained based on the illustrated embodiment.
The two opposing sides of the quadrilateral flat metal plate are bent to a predetermined height so that the center portions of each side extend deeply inward and alternate, so that the outer protruding piece 1a and the inner protruding piece 1b are left and right symmetrical. A fitting groove 1C is formed therebetween.

In addition, an eyelet tube portion 1d is provided at the center position between each inner protrusion piece 1b, lb by pushing up from the outer bottom of the face plate, and a stepped notch 1 is provided on the front plane portion of the eyelet tube portion 1d.
e is recessed to a desired depth to form an integrated substrate 1.

Next, the central part of the band-shaped metal plate is recessed and the eyelet tube part 1d is
A hole 2a into which the blade can be inserted is bored, and the area continuous with the central part is raised and raised at the same angle to form an inclined wing, and then horizontal pressing parts 2b, 2b are formed at the ends of the inclined wing. form,
Further, claw portions 2C, 2c are provided continuously to the respective pressing portions 2b, 2b to protrude in the longitudinal direction, thereby forming an integral fastener 2.

Further, the fastener 2 is pivoted onto the substrate 1 with the hole 2a fitting into the eyelet tube portion 1d, the eyelet tube portion 1d is caulked, and the fastener 2 is rotated onto the substrate 1. By attaching it freely, it constitutes a stud lath stopper A.

In the above configuration, the lath 4 is attached to the stud 3 by bending the lip tip of the lip channel steel inward to form the inwardly bent ends 3a, 3a.
Insert the lath stopper A, which is rotatably arranged parallel to the projecting pieces 1a and lb on both sides, into the stud, and fit the inwardly bent ends 3a and 3a of the stud into the fitting grooves 1c and lc of the board. Then, rotate the fastener 2 in a direction transverse to the longitudinal direction of the stud to stably and securely fit the lath stopper A to the stud 3 (Fig. 3,
(See Figure 4).

Next, as shown in FIG. 5, the laths 4 are attached to each stud 3 in such a manner that they are hooked to the claws 2C of the lath stoppers A that project laterally from the side surfaces of the studs 3, and then as shown in FIG. As shown, bend the claw portion 2C onto the lath and attach the lath 4 to the stud 3.
The installation to the stud is completed by clamping and holding it between the sides of the stud.

As described above, the present invention attaches the lath to the stud by using a lath stopper that can be easily and inexpensively provided by press forming, so there is no need to cut into the stud as in the past, and the stud It can improve productivity and provide inexpensive studs.

Furthermore, when transporting long studs from the factory to the site, it is possible to transport large quantities and quickly without worrying about crushing the erect ears as in the past.

Furthermore, even if there is a design change during construction, there is no need to make corrections to make the lug stoppers lie sideways.

The lath stopper of the present invention can clamp and hold the inwardly bent end of the stud between the fitting groove of the board and the pressing part of the fastener to prevent the end from expanding, thereby reinforcing the stud. It also has the effect of

A second embodiment of the lath stopper is shown in FIG.
In this second embodiment, mutually parallel claw parts 5a, 5a are made to protrude from both left corners of one quadrilateral board 5, and also from both right corners, the claw parts are directed oppositely to the left claw parts. The claw portions 5b, 5b of are made to protrude in parallel.

Further, a clamping part 5C is provided on the hanging side of the board located between each of the left claws 5a, 5a, and the left clamping part 5C is also provided at an intermediate position between each of the right claws 5b, 5b. A clamping portion 5d is provided opposite to the clamping portion 5d.

Each clamping portion 5 of the lath stopper in this second embodiment
C and 5d hold the inwardly bent end 3a of the stud 3, and the claws 5a and 5b are bent to perform lath fastening.
