Abstract: A firewood cord roof disposed on the top of a firewood cord to protect it against bad weather, thus, the firewood cords will dry, stay dry, and ready to use at its maximum. The firewood cord roof looks like a gable roof on the top of a house, here it is a gable roof on the top of the cord of firewood. The firewood cord roof is firmly attached to lower logs of the firewood cord so as not to be thrown down by the bad weather. The firewood cord roof comprises a wooden and plastic membrane framework structure disposed above the firewood cord and a roof covering membrane structure fixed on the wooden and plastic membrane framework structure and covering it, as well as the entire top surface of the firewood cord. Both structures capping the firewood cord like a gable roof on top of a house.

Abstract: In a balcony comprising parallel transverse boards forming a floor, transverse joists and longitudinal parallel joists supporting the transverse boards, the installation of a watertight underdeck membrane above each pair of longitudinal joists protects the structure from decomposing by recuperating water infiltrating between boards. The membrane comprises flat sloped zones and a foldable gutter shaped zone between two flat zones. The gutter zone becomes progressively deeper from upstream till downstream by stretching it with fingers. At the most upstream point of the balcony, above the first transverse joist attached against a wall of a construction, the gutter zone is completely flattened to bend the membrane and put it against the wall, thus acting as a flashing which collects water flowing along the wall before infiltrating into joists. The membrane is rollable for facilitating transportation and also to cut at a desired length according to balcony length for avoiding unnecessary junction.

Abstract: The present invention relates to a watertight sub-floor system for balcony or roof, in the form of a semi-rigid rollable plank of corrugated polymeric type installed in juxtaposition to form a waterproof flooring between boards and beams. Under-plank are unwrapped and cut at a desired length to avoid transverse junction with respect to water flow. Under-planks overlap parallel to water flow without loss of sealing. The corrugated under-plank has a design of crests and dips, crests widened and sloping to make possible the receiving of screws from deck board, thereby permitting the descent of water trickling from around the damaging screwing of the under-plank, and dips which bear no perforations from screwing and merely allow water to run off to protect wood structures of patios, balconies or terraces against moisture causing premature rot and to protect objects (bike, mowers . . . ) under a deck.

Abstract: An electronic spreadsheet or hand user calculator consists of an array of cells some containing formulas some into which a user enters stair dimension values such as total rise and run. After the user has entered such values the formulas proceed to other stair dimension calculations; then results are displayed on the spreadsheet. The system provides a facility not available on conventional electronic stair calculator spreadsheets: the first column provides results corresponding to initial values entered by the user and a second column, next to the first, allows to compare stair dimensions when the user plugs a different number of steps. For example an entered total rise of 111? and run of 10.5? will give, in the first column 14 steps each having a rise of 7.4?. Using a second column to compare stair dimension results for 15 steps shows a rise of 6.94?.

Abstract: A support for steps, having the shape of a triangular corner plate to be installed one after the other along a stringer. The sides of this support are reinforced, horizontally and vertically by a 90 degree fold, to fix the steps and risers. The ends are wider and possess a number of fixing holes to provide more stability when fixed against a stringer. The horizontal side is ended by a projecting horizontal rule. The wide part of the vertical side is flanked by vertical graduations. The horizontal rule is set against a stringer at a desired step run and the vertical graduations are set against the stringer at a desired step rise. The horizontal rule overlaps the vertical graduations of the preceding support.

Abstract: A support for steps, having the shape of a triangular corner plate to be installed one after the other along a stringer. The sides of this support are reinforced, horizontally and vertically, to fix the steps and risers. The ends are wider so successive supports overlap when installed. The wide part of the horizontal side includes in one embodiment a horizontal adjustment slit and the wide part of the vertical side includes a series of holes, at least one coinciding with the slit at the time of the installation on the stringer. Each wide part includes a second series of fixing holes spaced apart to secure the wide parts to the stringer. In another embodiment there is no slit but instead there is a pair of graduation rulers which overlap and permit direct reading of the width and of the height.
