Abstract
The utility model introduces a height-adjustable light steel keel used for paving wood floors, which is composed of a keel, a movable steel clamp, a square nut and an adjusting screw, wherein the keel is composed of a bottom board with a groove and a biplanar symmetrical vertical groove. The cross section of the keel is in a C shape, and the center of the keel is provided with the movable steel clamp. A wood floor is clamped by the upper end of the movable steel clamp, and the lower end of the movable steel clamp is clamped on a lateral wing of the biplanar vertical groove. A movable shim and the square nut are arranged below the bottom board of the keel for fixing the adjusting screw and connecting the light steel keel. The height of the light steel keel is adjusted by the adjusting screw according to the height of the planeness of the ground surface.
Description
Technical field: the utility model belongs to the cassette keel field that the decoration industry wood flooring is laid usefulness.Particularly belong to wood flooring and lay the height adjustable cassette lightgage steel joist field of usefulness.
Background technology: the decoration industry wood flooring is laid the keel of usefulness at present, mostly adopt rough ground, this keel are laid wood flooring, install loaded down with trivial details, price is high, time one long, occur distortion easily, play drum, cracking phenomena, though the keel that light steel, aluminium alloys or other material are made also occur at present, can solve distortion, a drum, the cracking phenomena of appearance.But because the smooth problem that the good bad influence wood flooring of ground layer planeness is laid also is not resolved.
Summary of the invention: the purpose of this utility model, invented a kind of lightgage steel joist that can adjust height exactly, when ground basic unit is uneven, can utilizes and adjust the leveling of key screw keel, reach the smooth of wood flooring laying.
The utility model is by keel, movable steel card, square nut and adjustment screw are formed, keel of the present utility model are made up of the vertical groove of two sides symmetry and base plate, keel are whole press forming, the cross section is " c " shape, the material of keel is zinc-plated cold-pressed steels, being commonly called as light steel. the centre of keel is movable steel cards, wood flooring is blocked in the upper end of movable steel card, block on the flank of two vertical grooves of keel the lower end, and the adjustment screw is housed on the base plate, with the fixing screw of adjusting of square nut, adjusting the key screw removable insole pieces holds out against, the sectional area of keel is wide to be 30mm, and height is 15mm, and movable steel card height is 12mm, the base is wide to be the wide 25mm of being of 25mm square nut, long is the vertical groove in 40mm two sides of the present utility model, can play spring action, can block square nut again.
Wood flooring out-of-flatness phenomenon appears in the utility model when having solved and having caused wood flooring to lay because of the ground out-of-flatness.The utlity model has cheap, easy construction, distortion fast, do not occur, play drum, cracking phenomena, feel is comfortable, and it is convenient to change, the advantage that the fire retardant anticorrosion performance is good.
