The present invention relates to a collapse alarm apparatus for a temporary structure which detects a collapse risk of a temporary structure installed in various construction sites in advance and generates an alarm sound. More particularly, the present invention relates to a collapse alarm apparatus for a building, It is possible to eliminate the restriction on the installation by greatly simplifying the installation, and it is possible to adjust the horizontal alignment quickly and precisely regardless of the installation on any temporary structure so as to facilitate the installation and to prevent the malfunction, The present invention relates to a collapse alarm apparatus for a building, which can greatly improve practicality by freely setting a detection range of an inclination slope according to a location.

Generally, in the construction site, temporary structures such as horseshoes, scaffolds, toilets, and guard posts are installed to support the structure alone or during the construction period.

However, there is a risk of collapse due to the subsidence or weakening of the ground due to the load of the concrete or heavy rain. In recent years, there has been a problem in that the bridge concrete installation There were cases where the damage occurred due to the collapse of the form hillside, the scouring of the scaffold during the exterior finishing work, the collapse of the slag during the excavation work, the collapse of the tunnel excavated surface during the tunnel operation, and the collapse of the subway construction site.

In order to prevent human injury due to the collapse of such a hypothetical structure, an automatic alarm device for sudden collapse of a building which previously senses the risk of collapse of a hull used in a construction site and generates an alarm sound is disclosed in Patent No. 10-1358056 The alarm device is configured to detect a leaning of the tide early by using a tilt detection switch having a simple structure to generate an alarm sound.

However, according to the conventional warning device having the above-described structure, the electric contact point is formed at the moment of contact with the inner surface of the closed container in accordance with the tilting of the spherical additional trough installed in the pendulum- It is not easy to install in horizontal or vertical direction so that it does not tilt to the side where the sphere is added every time the installation is performed on each of the pseudo-structures, and malfunction occurs when the horizontal or vertical is not correctly set. There was a problem to be done.

In addition, since the conventional alarm device has a bulky shape due to the contact structure of pendulum type, it is difficult to install in a narrow space, so that the installation of the alarm device is restricted. In addition, Since the detection range of the tilt can not be set freely, there is a problem that practicality is significantly lowered.
