Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for constructing outer walls, fences, partitions, etc. of buildings.

Conventional technology Recently, lightweight concrete plates (ALC) have been increasingly used for the exterior walls of wooden or steel structures due to demands for shorter construction periods, easier workability, fire protection, water resistance, etc. Ta. These lightweight concrete plates are conventionally finished to have predetermined length, width, and thickness at a lightweight concrete plate manufacturing factory, and these lightweight concrete plates are transported to the construction site and used for construction. Attach to a fixed steel frame across the pillars of objects, between foundation frame materials and beam materials, and fix lightweight concrete plates to the steel frame with mounting bolts, drill screws, etc. for external walls, beams, partitions, etc. was forming.

Problems to be Solved by the Invention As mentioned above, conventionally, when constructing the outer wall of a wooden or steel structure building by attaching concrete plates, latticework was applied to the pillars, foundation frames, beams, etc. of the building. After fixing the steel frames by welding, screwing, etc., the concrete plates are loaded onto individual concrete plate transport vehicles from concrete plate manufacturing factories, storage warehouses, etc., and transported to the construction site, where multiple workers remove the individual concrete plates. The concrete plates were held at both ends and transported to the installation location and placed against the steel frame, and then other workers fixed the concrete plates to columns, lattice-shaped mounting frames, etc. with screws, nails, etc. Therefore, it takes a long time to attach the outer wall,
Scaffolding had to be constructed for each level of concrete slabs.
Filling the gaps between adjacent concrete plates to prevent water intrusion and surface painting had to be carried out on each concrete plate at a high place on the construction site, requiring a long construction period and a large number of workers. The disadvantage was that it required a large amount of construction cost.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a method for constructing an exterior wall of a Shinto Heavy Industries housing using two lightweight concrete panels (ALC) arranged with side panel openings facing each other on both sides. The narrowed portions at both ends of the two groove shaped steels are formed inside the side plates of one of the groove shaped steels, and the outer diameter of the opposing side plates is smaller than the inner diameter of the side plate of the one groove shaped steel. A process of fitting the two layers into a rectangular shape, and spot welding the side plate parts of the double layers that have been fitted and superimposed to form a rectangular frame, and placing concrete plates side by side in front of the rectangular frame, and then inserting the concrete plate and the rectangular frame from above the concrete plate. The process of fixing the rectangular frame and the concrete plate by driving nails or screwing through the side plates of the building, the pillars of the building, the foundation frame material,
The problem with the conventional method is that the bottom side of an L-shaped mounting member for external wall mounting is fixed to a beam material, etc., and the side plate of the rectangular frame with the concrete plate attached to the rising side of the L-shaped mounting member is attached with a bolt nut. This is the solution.

Function: As described above, the present invention uses groove sections having the same size in cross section, and inserts the outer diameter of the end of the side plate of the groove section inside the open end of one of the two opposing groove sections. The ends of the other two groove sections formed to be smaller than the inner diameter of the opening of one groove section are fitted at 90 degrees, and the double layer is welded to form a rectangular frame. Since we welded a double-layered part on the inside of the two opposed groove sections in the same direction as the other groove section and fitted with the narrow ends of the other groove sections, the entire surface of the rectangular frame is uniform. When concrete plates are lined up on the surface of a rectangular frame, there will be no gap between the miso shaped steel and the surface of each concrete plate, and they will be glued together to form a uniform plane. Then, the rectangular frame is fitted so as to close the space between the columns and the space between the beam and the foundation frame, and one side is attached to the column, the beam, and the foundation frame for L-shaped installation. By attaching the side plate of the rectangular frame to the other side of the member with screws, the work of attaching the outer wall of the building can be completed within a short period of time.

Furthermore, it is possible to fill the gap between the concrete plates attached to the rectangular frame in advance with a water leakage preventive agent and apply paint to the surface of the concrete plates.
