Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a ceiling structure using ALC panels that is used for horizontal parts such as roofs of buildings and floors of upper floors.

[Prior art]

ALC panels (lightweight aerated concrete panels) are used on the roofs and floors of upper floors of buildings.
There are cases where the back side of the panel is used as it is as a bare ceiling, but in such cases vibration may cause
ALC concrete powder falls from the ceiling joints due to friction on the ALC panels, etc.
There are many cases of people staining the floors downstairs. Conventionally, this has been dealt with as follows.

The first method is to provide another suspended ceiling on the ceiling surface of the ALC panel so that the concrete powder of the ALC is received by this suspended ceiling. However, there is a drawback that a suspended ceiling must be provided in buildings that do not originally require a suspended ceiling, such as factories and warehouses.

Next, the joints on the back of the panel and the joints with the frame and beams are sealed from the back of the panel, and the entire ceiling surface is sprayed to the same degree as the exterior material, so that the ALC concrete powder can be removed from the ceiling joints. Structures have also been proposed to prevent the panels from falling, but these treatments involve sealing or spraying the panels from below after the panels are installed as ceiling materials, so it is necessary to erect temporary scaffolding. ,
Moreover, the worker must work while facing upward.

For this reason, there were many inconveniences in terms of work efficiency and costs, and the finished appearance was not very good.

[Problem to be solved] The present invention was created in view of the above circumstances,
There is no need to construct a suspended ceiling to prevent powder from falling from the ALC panel, and there is no need to work from the back of the ceiling panel.Therefore, it is possible to shorten ceiling formation work time and save costs, and it also has a good appearance. become something
The purpose is to provide a ceiling structure using ALC panels.

[Means to solve problems]

The present invention is designed so that a short piece of ALC panel is on top of the beam, so that
In a ceiling structure using ALC panels in which ALC panels are installed, the left and right side surfaces of each ALC panel have protrusions 1a below their end faces, and the protrusions are chamfered in the longitudinal direction. At the same time, a groove 3 is formed in the protrusion 1a, a foam 4 is fixed in the groove 3 on one side of the ALC panel, and a pre-seal is applied to the back surface and chamfered part of each ALC panel. The finish is applied, and there is a slight gap between adjacent panels of the ALC panels, and grooves 3 and 3 between the ALC panels.
A foam 4 fixed to one of the ALC panels is inserted into the groove formed between the two ALC panels, and a joint mortar 8 is filled into the joint groove 5 between the ALC panels formed on top of the foam 4. This is a ceiling structure using ALC panels, which is characterized by a molded sealing material laid on the beams between the beams.

That is, each ALC used in the ceiling structure of the present invention
As shown in FIG. 2, the left and right sides of the panel have protrusions 1a below their end faces, and the protrusions are chamfered in the longitudinal direction, and grooves 3 are formed in the protrusions 1a. is formed, and the corresponding
A foam 4 is fixed in the groove 3 on one side of the ALC panel, and a pre-seal finish is applied to the back surface and chamfered portion of each ALC panel. Therefore, this ALC panel 1 should be aligned perpendicularly to the length of the beam so that a short piece of the ALC panel is on top of the beam 6, as shown in FIG.
If ALC panels are installed to form a ceiling structure, the third
As shown in the figure, on the left and right side contact surfaces 2a of mutually adjacent ALC panels, there are
The grooves 3 provided in the longitudinal direction are opposed to each other to form a groove, and the foam fixed in one of the grooves 3 of the ALC panel is fitted into this groove. At the same time, a joint groove 5 is formed on the upper surface side of each ALC panel by the end surfaces of the upper left and right side surfaces of the panels and the protrusions 1a and 1a'.

Another feature of the present invention is that when installing the ALC panel, a slight gap is provided between the left and right side surfaces 2a of the panel. In this way, a slight gap is created between the panels to prevent the generation of concrete powder due to vibration, and anything that falls through the gap is inserted into the groove formed between the grooves 3 and 3 between the ALC panels. The foam can prevent it from falling.

In addition, in this invention, the short side of the ALC panel is
As shown in FIG. 4, it is laid on a beam 6, and a molded sealing material 7 laid on the beam is laid between the beam 6 and the ALC panel.
The presence of this molded sealing material 7 also prevents powder from falling from this portion.

In addition, since the protrusions of the ALC panel used in this invention are chamfered in the longitudinal direction,
It is possible to prevent the edges from chipping when installing the ALC panel, and the chamfered part and the back surface of the panel are given a pre-seal finish to prevent powder from falling from this area as well.

Further, the foam 4 used in the present invention is made of, for example, extruded polyethylene foam,
Prior to laying the panel, it is fitted into one of the grooves 3 over the entire length of the groove and fixed to the panel with adhesive, nails, or the like. The preferred shape of this foam is a round bar as shown in the drawings, but the shape of the foam can also be changed in accordance with the change in the shape of the grooves 3.

When forming the ceiling structure of the present invention, a molded sealing material 7 is laid in advance on the beam material 6 so that there is no need to seal the joint between the ALC panel and the beam material after the panels are laid. , on which an ALC panel with foam 4 fixed in one groove is laid.
After the panels are laid in this way and the foam 4 is present between the grooves of each panel, joint mortar 8 is filled in the joint grooves 5 shown in FIG. 3, and the panels are joined together. The ceiling can be constructed by

In this way, the joint mortar 8 is used to join the panels together.

[Effect of idea]

The effects of the ceiling structure of the present invention are as follows.

The ALC panels are laid with a slight gap between them, and foam is inserted into the grooves between the panels to prevent powder from falling between the panels. .

Furthermore, since there is a molded sealing material between the beam material and the panel, it is possible to prevent powder from falling from this area.

Furthermore, since the ALC panel is chamfered and a pre-seal is applied to the chamfer and the back of the panel, there is no possibility of powder falling from the panel itself.

Furthermore, the panels themselves are interconnected with joint mortar on the top surface, and the present invention has a structure in which the molded sealant and foam are not visible from below, so it is not necessary to perform joint treatment from below, etc. in the conventional method. Unlike ceiling structures with post-finishing, this creates a ceiling structure with a good appearance.

Moreover, the ceiling structure of this invention does not require construction from the bottom of the panel, so there is no need for scaffolding.
This ceiling structure saves construction costs and is easy to construct.
