Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention enables interior materials to be placed on the inside of a wall by attaching a concrete plate to the outer surface of a steel frame on which interior materials can be attached. This invention relates to an exterior wall panel that can be installed without welding work, improves construction efficiency at the construction site, and increases work safety.

[Conventional technology]

In recent years, concrete panels have been frequently used for exterior walls, partition walls, etc. to improve the fire resistance and sound insulation of houses.

Such concrete panels are heavier than regular wall panels, which have side plates attached to the front and back of the frame to simultaneously form the inner and outer surfaces of the wall, and because interior materials cannot be attached to concrete panels, concrete panels are It will be attached to the frame material independently from the interior material.

The upper and lower ends of the concrete panels are bolted together via crosspieces that run along the upper and lower floor beams that form the frame members of the house, while the interior materials are attached in the form of studs between the upper and lower floor beams. The interior material was attached to the inner surface of the base material.

[Problem to be solved by the invention]

However, conventionally, attaching the base material to the upper and lower floor beams was done by welding at the construction site, which required time and effort, and it was necessary to secure welders just for this work. Therefore, it takes time and effort to secure work personnel and other arrangements, which tends to delay the construction period. Furthermore, since fire is used in welding work, there are also problems in terms of fire safety.

Furthermore, since the base material attached by welding is permanently fixed, it is difficult to correct its position, and correction requires time and effort.

The present invention aims to provide an exterior wall panel that can eliminate welding work for attaching interior materials, improve fire protection and safety, and improve construction efficiency at the construction site.

[Means to solve the problem]

The present invention includes horizontal and vertical upper frame materials, lower frame materials,
A lower mounting bracket made of steel that has a lower mounting piece attached to each of the upper frame members and a lower board facing downward, and a vertical member that connects the upper mounting piece and the lower mounting piece and is used for attaching interior materials. This is an external wall panel in which a concrete plate is attached to the outer surface of a frame by bolting to the upper frame material and the lower frame material.

[Effect]

The frame is made up of the upper mounting bracket, the lower mounting bracket, and the vertical member that connects the two, so the frame can easily adapt to changes in the dimensions of the concrete plate, allowing for the standardization of parts. It can be promoted.

In addition, since interior materials can be attached to the vertical members, there is no need to attach members for attaching the vertical members to the frame members as in the past, eliminating welding work at the construction site, improving work efficiency. Can improve safety.
