The ceiling tile ladder attachment device holds ceiling tiles while a user is working on a ladder to install or replace the tiles in the ceiling, in addition to storing tiles that have to be removed from the ceiling and held for re-installation after performing other maintenance above the tiles. The ceiling tile ladder attachment device includes a rectangular wire rack that attaches to the back side of a ladder. The wire rack has a hook part on the back side. The hook part preferably attaches to the wire rack in two places to prevent the wire rack from swinging or slipping on the ladder. The hook part includes adjustable hook points for different styles and sizes of step ladders. The user can attach the ceiling tile ladder attachment device to the backside of the ladder using the hook part.

A multi-use support stand used for holding various types of building materials and used in other types of construction projects. The support stand includes a horizontal foot brace and a horizontal cross brace attached to a bottom of a vertical support post. An oblique support post is attached to a top portion of the vertical support post and a portion of the foot brace. One end of a horizontal extension arm is attached to a sliding “U” shaped channel. The channel is received around a portion of the oblique support post. A pin is received in a selected pin hole in the side of the support post for securing the sliding channel to the oblique support post. When a first and second support stands are placed next to each other, the horizontal extension arms are used for holding loads of sheet rock, plywood, bench table top, working platform, shelving, footbridge sections, dimensional lumber, and other application specific items needing to be supported horizontally or an elevated obtuse angle.

A levelling spacer device for the laying of slab-shaped products for coating surfaces, including at least one base having a lower surface and an opposite upper surface defining a support plane for two slab-shaped products placed side by side, a spacer bridge perimetrically delimiting a through opening adapted to be crossed by a pressure wedge along a crossing direction, wherein the bridge has at least two legs placed side by side between each other along a flanking direction orthogonal to the crossing direction and each one projecting from a respective portion of the upper surface of the base, in a direction orthogonal thereto, wherein each leg of the bridge is frangibly connected to the respective base portion, and a crosspiece, which joins the top of the two legs along the flanking direction, wherein each leg has an inner sidewall and an opposite outer sidewall converging on each other.

A wall and ceiling panel system which utilizes a concealed resilient beam for securing a panel to a wall or ceiling structure is disclosed. A wall and ceiling panel system having features of the present invention can comprise a panel configured for releasable attachment to a latching assembly. The latching assembly can comprise a resilient beam dynamically secured to a base bracket so as to allow the resilient beam to deflect relative to the base bracket during the panel installation and removal process. The panel can comprise a keyed flange having at least one locking slot configured to mate with the resilient beam, with the panel becoming secured to the latching assembly once the panel's key flange is mated with the resilient beam.

A sleeve for the centering of fasteners when installing structural parts on substructure of a building envelope is designed substantially as a hollow cylindrical sleeve body or split hollow cylindrical sleeve body. It has at least two gutter-like shell elements each having a head end and a rear end. The shell elements are grouped symmetrically about a central axis A and span between them a middle space with inner surfaces facing each other. The shell elements are spaced apart from each other and separated by axially parallel longitudinal slots, except for a connecting joint section at the head end. These sleeves are placed on a fastener and allow a precise centering in the predrilled hole of a facade plate, for example. The sleeve remains in the predrilled hole until such time as the centering of the fastener has been accomplished and is then ejected safely by driving the fastener home.

A device for leveling and aligning tiles and method for leveling and aligning tiles are disclosed. In one embodiment, the leveling device includes a body and two spaced and parallel strip members extending transversely from the body. Each of the spaced and parallel strip members extend to the front and rear of the body. Two opposing lateral open windows are formed in the body. A breakaway section is defined along the body. A wedge device is provided for penetrating one or more of the two opposing lateral open windows and exerting a force on the tiles for leveling them relative to each other.

The present invention relates to a novel tongue and groove installation device. The device allows a single person to install tongue and groove ceiling boards without the assistance of another. The device comprises a first holding component and a second holding component spaced apart, with a spacer component positioned at one end, between the first and second holding components. The space component is secured at one end, leaving the second end of the first and second holding components open. Typically, the length of the first and second holding components is longer than a width of a tongue and groove ceiling board. Further, the thickness of the spacer component is greater than the thickness of a tongue and groove ceiling board, such that the device slides onto the board with ease.

The present invention provides a method for constructing an access floor by using unmanned robot, the method comprising: a first step (S100) of constructing an installation frame (10) and a peripheral slab (60) formed on the periphery of the installation frame; a second step (S200) of positioning the unmanned robot on the peripheral slab (60); and a third step (S300) of coupling a floor (30) to the installation frame (10) by the unmanned robot while moving along the peripheral slab (60). According to the present invention, an automated robot can install a mat and floor in place of a worker performing dangerous floor installation work, so as to prevent the occurrence of workplace safety accidents. Furthermore, through the installation of a mat and floor by the robot, floor installation location selection and leveling work can be quickly performed, so as to reduce the construction costs and shorten the construction period.
