Description

[Detailed description of the invention] (Field of industrial application) The present invention is a hanger mounting device for connecting the clamping parts and tensioning the roof sheets when assembling the clamping steel plate roof in roofing work. Regarding.

(Prior art and problems) A steel plate roof of the clasp type is one in which two left and right steel plates are assembled into a set in a concave and convex waveform, and the hook-shaped inner and outer clasp parts are clasp-fitted at the top of the waveform. A ridge with a pipe-like cross section is formed at the top of the waveform.

By the way, such a fastened steel plate roof is assembled only by so-called fastened fitting without using screws or fasteners, so the fastened fitting is carried out strongly and reliably, and the fixing parts of beams etc. It must be fixed immovably so that it does not float up. Hanging clips have traditionally been used to attach to fixed parts such as beams, but the conventional hanging hanging device has a cylindrical suspension fitting 40 between the clamping parts as shown in Fig. 4. Stop part 40a
Since it was only necessary to insert and lock the metal plate roof 45, when assembling, apply the suspender metal fittings to the inner frame part 45a of one steel plate roof 45, and then fit the outer frame part 46a of the other steel plate roof 46 from above. During this period, the hanger may come off upward, move back and forth or left and right, or even fall off from the mounting position, making it difficult to fix the hanger.

Temporary fixing using adhesive tape or the like is a common method for fixing the suspension fittings 40, but temporarily fixing a large number of suspension fittings is extremely troublesome and requires a great deal of effort and time. There is also a problem in that a considerable amount of temporary fixing material is required, resulting in high costs.

(Technical Problem) Therefore, in the present invention, the suspender metal fittings can be reliably set between the clamping parts, and once set, they are clamped elastically to prevent them from coming off upwards or moving loosely. To provide a technical object to easily and quickly attach suspender metal fittings without temporarily fixing them.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the suspender attachment device for the clamping steel plate roof according to the present invention has the following features: Hanging metal fittings 5 between
In a device in which a semi-cylindrical locking part 6 at the upper part of the hanger fitting 5 is inserted and locked, an inner frame part 3 fitted into the locking part 6 is attached to the tip of the locking part 6 of the suspender metal fitting 5. A protruding locking bullet 7 for pressing and a guide projection 9 having a circular arc surface larger than the radius of curvature of the locking bullet 7 are integrally formed so as to press the locking bullet from the outer surface. It is what it is.

Then, a plurality of pressing locking elastic pieces 7 at the tip of the locking part 6 are formed in a row at intervals, and
It is preferable that the guide protrusions 9 be formed at both front and rear ends with the locking elastic pieces 7 facing inside.

(effect) The above technical means works as follows.

To attach the suspender fittings 5, proceed as follows. First, the locking part 6 at the upper end of the hanger metal fitting 5 is applied to one of the inner ribs 3 of the steel plate roof 1, and as shown in FIG. The inner part 3 is connected at two points: the locking bullet piece 7 at the tip and the locking step 8.
It clamps and locks it oppressively and holds it. At this time, the locking bullet 7 comes into contact with the outer surface of the inner rib portion 3 and slides on the outer surface, and when it climbs over the peak of the maximum diameter, it engages with the stepped portion 3a and becomes a tightly fitted state. Next, the outer edge part 4 of the other steel plate roof 2 is placed over it, and when it is forcibly press-fitted, it slides on the guide protrusion 9 and fits together, so that both the inner and outer parts of the left and right steel plate roofs 1 and 2 are fitted together as shown in FIG. The three parts, the hanging parts 3 and 4 and the locking part 6 of the hanger fitting 5, are integrally connected. In this state, the locking step 8 of the suspender fitting 5 is locked upwardly to the tip 3b of the inner bar, and the locking bullet 7 is locked to the step 3a, so that It becomes completely locked.

The lower end of the hanger fitting 5 is vertically slidably held between the left and right mounting plates 12, 12 on the upper part of the mounting frame 11, and is in an upwardly pulled state before use. In this state, the engagement protrusion 13 is engaged with the engagement claw 14 so that the engagement protrusion 13 stops at a fixed position where it is forcibly pushed down and becomes immovable. Further, a wedge-shaped protrusion 15 is forcibly press-fitted between the left and right mounting plates 12, 12 to strengthen the clamping force.

(Effects) The present invention has the above-mentioned configuration, and when the semi-cylindrical locking part of the suspension fitting is forcedly press-fitted into one of the inner ribs of the steel plate roof, in the fitted state, A locking piece for pressing elastically presses the outer surface of the inner roof part to maintain the temporarily fixed state, and therefore, until the outer part of the other steel plate roof is fitted on top of it. During this process, there is no need to worry about the inner part and the engaging part of the hanger coming off or moving loosely.Furthermore, when the outer part is fitted together, the guiding protrusions serve as a guide to prevent the outer part from coming off. It is possible to quickly, smoothly and accurately perform the fitting and mounting of the hinge parts. Therefore, there is no need to temporarily fix the suspender metal fittings using an auxiliary material such as adhesive tape as in the past, so the work can be carried out efficiently and it is advantageous in terms of cost.

(Example) The hanger fitting 5 is formed by bending a thin elastic metal plate such as a steel plate, and the locking part 6 is formed into a semi-cylindrical shape according to the shape and size of the locking part. A locking step portion 8 is formed.

The locking bullet piece 7 is formed into an arc smaller than the radius of curvature of the locking portion 6 and is caused to protrude inward. The guide protrusion 9 is shaped to follow the arc of the locking portion 6, and is formed on both sides of the locking elastic piece 7 or between both sides.

It is also possible to provide a threaded socket at the lower part of the hanger fitting 5, and screw the mounting rod into the socket to tighten it, thereby connecting it to a fixed part such as a beam with a screw.
