Description

[Detailed explanation of the invention] (Industrial application field) This invention is very dangerous when snow accumulated on the roofs of factories, warehouses, gymnasiums, etc. falls, so this invention is designed to be attached to the roofs to prevent snow from falling. This relates to snow stoppers.

(Prior art) There are many types of snow stoppers with various structures, but basically they consist of a roof attachment part and a snow stopper part, and the snow stopper part is equipped with a snow stopper board or A fitting groove is formed for the retaining angle, and the mounting part is configured to be installed by clamping a part of the roof, depending on the type of roof, and the clamping means is a clamping bolt connected to the clamping member. This means that a part of the roof is held in place by the holding members. In other words, metal fittings for vertical flat roofs are published in Japanese Utility Model Publication No. 57-181827, metal fittings for flat roofs are published in Japanese Utility Model Publication No. 56-43472, and metal fittings for tiled roofs are published in Japanese Utility Model Publication No. 56.
-52354, metal fittings for folded roofs are shown in No. 58-26262, etc.

(Problem to be solved by the invention) The clamping method for attaching metal fittings to the roof involves attaching a clamping bolt to the clamping member and clamping a part of the roof with the clamping member, as described above. The component must be movable, and the clamping bolt is inserted into the movable part and the nut is screwed together, so the nut is loosely screwed together before it is installed on the roof. may become detached from the bolt. Furthermore, if the nut is tightened to prevent it from coming off, there is the inconvenience of having to loosen the nut when installing it on the roof.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention adds a spring to a part of the known snow stopper. That is, in a snow stopper that is mounted by compressing a part of the roof with clamping parts connected with clamping bolts, a compression spring is interposed between the clamping parts.

Therefore, the spring forces the clamping member in the direction of separation, so if the nut screwed onto the clamping bolt is tightened against the force of the spring, the nut will not loosen as in the conventional case. It does not come off from the bolt and can maintain an appropriate distance between the clamping members.

(Example) An embodiment of the present invention will now be described based on the drawings.

Figures 1 and 2 show the present invention applied to metal fittings for vertical flat roofs. Long zinc sheet that covered the roof a
A snow stopper to be attached to a vertical flat roof formed by overlapping and bending the adjacent end faces of ，
A clamping bolt 3 is inserted between 2' and a tightening nut 4 is screwed onto the bolt 3. In the present invention, a spring 5 for winding the bolt 3 is attached to the aforementioned metal fitting. It is something. Therefore, when it is not attached to the roof, the clamping plates 2, 2' are open and the nut 4 is lightly tightened. When tightened, the connecting portion b is firmly held between the holding plates 2 and 2'.

Next, FIGS. 3 and 4 show the present invention applied to a snow stopper that is attached to a horizontal roof (also called a flat roof). A metal fitting for a horizontal roof made by folding a zinc plate or the like parallel to the ridgeline of the roof is provided with clamping plates 6, 6' vertically opposed to each other behind a snow stopper plate 1', and between the clamping plates 6, 6'. A clamping bolt 3 is inserted from below, and a nut 4' is screwed into the threaded portion of the bolt protruding from the clamping plate 6'. In the present invention, a spring 5' is interposed between the clamping plates 6 and 6' in the aforementioned metal fitting. Therefore, since the upper clamping plates 6, 6' are in a raised state by the force of the spring 5', the tail end of the lower clamping plate 6 can be easily inserted into the folded part c of the roof, and the nut can be tightened. When 4' is tightened, the end portions of the clamping plates 6, 6' firmly clamp the folded portion c, and the metal fitting is attached to the roof.

This proposal is not limited to the above-mentioned metal fittings for vertical and flat roofs and metal fittings for horizontal roofs, but also applies to tile stick roofs,
It can be applied to all snow stoppers used on folded roofs and other roofs.

(Effects of the invention) As described above, the present invention has a simple structure in which a spring is attached to a snow stopper of a known structure, which prevents the nut from coming off, and since the clamping part is always open, the installation work is easy. can be done more effectively.

[Brief explanation of the drawing]

The figures show an example of the present invention. Figure 1 is a rear view of the metal fitting for a vertical flat roof, Figure 2 shows the installation state of the metal fitting, and Figure 3 is a sectional view of the metal fitting for a horizontal roof. FIG. 4 is a sectional view showing the mounting state of the metal fitting. 1, 1' are snow stopping boards, 2, 2', 6, 6' are clamping boards,
3, 3' are clamping bolts, 4, 4' are nuts, 5,
5' is the spring.

Claims (1)

[Scope of utility model registration request] This snow stopper is installed by pinching a part of the roof with a holding part connected with a pressure bolt, and has a compression spring interposed between the holding parts.
