Construction method of boardlike building elements

Claim 2

A construction method according to claim 1, wherein the boardlike building element has a groove formed in the lower edge face thereof in the lengthwise direction thereof, and an upper portion of the second fixture is inserted in the lower edge groove, whereby a lower portion of the boardlike building element is fixed to the building body.

Claim 3

A construction method according to claim 1, wherein the first fixture is composed of an L-shaped fixture having a vertical segment to be fixed to the building body and a horizontal segment extending horizontally from the vertical segment, and a straight fixture to be secured to the horizontal segment of the L-shaped fixture by a bolt; the horizontal segment and the straight fixture are formed with individual slots which extend as to cross each other and in which the bolt is inserted; and the slit is formed in the straight fixture.

Claim 4

A construction method according to claim 3, wherein the straight fixture is formed with slits which extend from either lateral edge thereof; the second fixture has leg segments extending along either lateral edge thereof which are to be inserted in the slits; the width of each leg segment is larger than that of the slit; a spacer made of synthetic resin is attached to a portion, projecting from the slit, of each leg segment; and each leg segment together with the spacer is inserted in the upper edge groove of the boardlike building element.

Claim 5

A construction method according to claim 1, wherein the upper edge groove of the boardlike building element extends over the whole width of the boardlike building element.

Claim 6

A construction method according to claim 2, wherein the lower edge groove of the boardlike building element extends over the whole width of the boardlike building element.

Claim 7

A construction method according to claim 1, wherein the groove is semi-circular in side view.

Claim 8

A construction method according to claim 2, wherein the lower edge groove of the boardlike building element is semi-circular in side view.

Claim 9

A construction method according to claim 1, wherein a third fixture is coupled to the distal edge portion of the horizontal segment of the first fixture, and an upper portion of the boardlike building element is pinched between the second and third fixtures, whereby the upper portion of the boardlike building element is prevented from inclining toward the wall surface.

Claim 10

A structure in which boardlike building elements are fixed to the wall surface of a building body in arranged form by the use of fixtures, comprising a groove formed in the upper edge face, in the lengthwise direction thereof, of each boardlike building element, a plurality of first fixtures each fixed to the building body such that a horizontal segment of the first fixture extends as to depart from the wall surface, a slit formed in a distal edge portion of the horizontal segment of each first fixture which extends parallel to the wall surface, and a plurality of second straight fixtures each fitted in the corresponding slit in the downward direction so that the lower edge of each second fixture is inserted in the upper edge groove of the corresponding boardlike building element, whereby an upper portion of each boardlike building element is fixed to the building body.

Claim 11

A construction method of fixing boardlike building elements to the wall surface of a building body in arranged form by the use of fixtures, each boardlike building element having grooves formed in the upper and lower edge faces thereof in the lengthwise direction thereof; and each fixture being composed of an L-shaped fixture to be fixed to the wall surface, a straight fixture to be coupled to the L-shaped fixture as to project horizontally therefrom which has first and second slits formed in a distal edge portion thereof in parallel to the wall surface, and first and second insert plates to be inserted in the first and second slits, respectively, of the straight fixture in the downward direction; comprising the steps of inserting the first insert plate in the first slit after the straight fixture is coupled to the L-shaped fixture, fitting a lower edge portion of the first insert plate in the upper edge groove of the boardlike building element arranged on the lower side, fitting an upper edge portion of the first insert plate in the lower edge groove of the boardlike building element arranged on the upper side, whereby the boardlike building elements vertically arranged are fixed to the wall surface, and inserting the second insert plate in the second slit, whereby the boardlike building element is prevented from shifting toward the wall surface.
