Raised floor and assembling method thereof
A raised floor and an assembling method thereof includes a plurality of raised floor boards, wherein a plurality of raised floor boards are assembled and connected to form an integrated floor, an edge of the integrated floor close to the wall is supported by a leveling beam, and leveling screws are arranged below connecting positions of two adjacent raised floor boards, a reserved expansion joint is arranged between the edge of the integrated floor and the wall, and a position above the integrated floor close to the wall is fixedly connected with frame beam by an expansion screw. An edge of the raised floor board body structure is processed, so that the raised floor boards can be assembled through lap joint and connection of structures, and supported through the leveling screws when they are in mutually lap joint for assembly.
1 . A method of assembling a raised floor, comprising the following steps:
step 1 : cleaning a base layer: preparing, classifying, placing and keeping clean construction tools, construction materials being floor boards and a support leg, and simultaneously clearing garbage and dust on the ground, and leveling the ground;
step 2 : laying down a horizontal line: before assembly, planning height of the raised floor according to an environment of a construction site and a use requirement, and then snap-lining through an ink fountain, and forming the horizontal line at an installed position, namely, a floor laying baseline;
step 3 : installing the beams: respectively installing a leveling beam ( 2 ) and a frame beam ( 5 );
step 4 : installing a leveling support leg: finding positions corresponding to preformed holes ( 17 ) according to a size of the raised floor, and arranging leveling screws ( 3 ) at the positions, so as to fix a support point of a floor board, and adjusting all the leveling screws ( 3 ) to a height approximately equal to a top end of the leveling beam ( 2 ); and
step 5 : laying the floor board, laying the raised floor boards ( 1 ), laying the floor board along the floor laying baseline, laying the raised floor boards ( 1 ) close to the positions of the leveling beam ( 2 ), and leaving the reserved expansion joint ( 4 ) so as to prevent the floor board from cracking or damaging integrated structure thereof due to climate and temperature changes, after laying a bottom plate close to the leveling beam ( 2 ), laying the bottom plate continuously with the raised floor boards ( 1 ), inserting an insertion rod ( 36 ) in leveling screws ( 3 ) into sockets ( 18 ), support and fixing the raised floor boards ( 1 ) through the leveling screws ( 3 ), and keeping preformed holes ( 17 ) above the leveling screws ( 3 ), and finely adjusting a height of the leveling screws ( 3 ) with the tools.
2 . The assembling method according to claim 1 , wherein: specific steps of installing the leveling beam ( 2 ) in step 3 are as follows:
the leveling beam ( 2 ) is calibrated by using a laser level gauge to ensure that horizontal misalignment of the floor over a three meters range does not exceed 0.5 mm, and the misalignment of a whole raised floor does not exceed 2 mm, and the leveling beam ( 2 ) is attached to a wall during installation, a bottom end of the leveling beam ( 2 ) is in contact with the ground during installing, a top end thereof is flush with the horizontal line, and then the leveling beam ( 2 ) is fixed on the wall through an expansion screw, so as to fix the leveling beam ( 2 );
specific steps of installing the frame beam ( 5 ) in step 3 are as follows:
step 3 - 1 : installing a leveling gasket ( 6 ), first attaching the leveling gasket ( 6 ) to the wall according to actual height of skirting line, and then fixing the leveling gasket ( 6 ) on the wall through the expansion screw; and
step 3 - 2 : installing the frame beam ( 5 ), providing the frame beam ( 5 ) according to the height of the skirting line, and placing the frame beam ( 5 ) close to the leveling gasket ( 6 ) to form a bottom frame of wallboard.
3 . The assembling method according to claim 1 , comprising a step 6 : installing the wallboard, wherein specific installing steps are as follows:
step 6 - 1 : installing the skirting line ( 8 ), attaching the skirting line ( 8 ) to the frame beam ( 5 ), and installing the skirting line ( 8 ) on the frame beam ( 5 ) through skirting buckle ( 7 ), thereby forming the skirting line of a wallboard; and
step 6 - 2 : installing the wallboard ( 9 ), installing the wallboard ( 9 ) above the skirting buckle ( 7 ), and fixing a bottom end of the wallboard ( 9 ) through a gap chamber formed by the skirting line ( 8 ) and the frame beam ( 5 ).
4 . The assembling method according to claim 1 , wherein specific operation of finely adjusting the height of the leveling screws ( 3 ) through the tools in step 5 is as follows: twisting the support column ( 32 ), and inserting a turning handle with a geometric shape in cross section into the cross chamber inside the support column ( 32 ), twisting the turning handle to cause the support column ( 32 ) to rotate, and changing the height of the support plate ( 31 ) through cooperation of an internal thread ( 34 ) and an external thread ( 35 ), and finely adjusting the height of the support plate ( 31 ) so that the support plate ( 31 ) maintains the same height as a top of the leveling beam ( 2 ), and keeping the height of the raised floor boards ( 1 ) consistent.
