A tile spacer comprises a base for engaging a bottom surface of tiles and a stem projecting upwardly from the base. The stem comprises two oppositely facing surfaces and two projections (36, 38) extending in opposite directions from the surfaces so that the stem and the projections define cross-shaped profile with corners for contacting corners of four tiles. At least one of the surfaces of the stem includes a recessed, i.e. set-back, area. The projections extend from the recessed areas. One or both projections can be removed from the stem by breaking the projection(s) so that the tile spacer can be used with four, three or two tiles depending on whether one or both projections is removed. The recessed areas confine any residual material of the projection(s) that is not removed when the projection(s) is broken at least substantially within the recessed area(s) and minimises or avoids altogether interference with laying tiles.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket (1), an insertion block (2) and pushing and clamping pliers (3), wherein the ceramic tile leveling bracket (1) is provided at the junction between two adjacent ceramic tiles (4), one end of the insertion block (2) is inserted into an insertion block through hole (16) of the ceramic tile leveling bracket (1), and the pushing and clamping pliers (3) push and clamp the insertion block (2) into the insertion block through hole (16), so that an insertion block bottom surface (21) is tangent to upper surfaces of the two ceramic tiles (4). The ceramic tile leveling and laying system is easy to operate, and helps to improve the laying efficiency and laying quality.

A leveling spacer device for laying sheet shaped products for the covering of surfaces, including a base, which may be positioned at the rear of a laying surface of at least two sheet shaped products being adjacent and placed side-by-side relative to a side-by-side direction, a separator element rising from, and perpendicular to, the base and configured to slide between the facing side walls of the two sheet shaped products placed side by side, a threaded stem rising from the separator element with a screw axis orthogonal to the base, a presser screwable onto the threaded stem and an anti-sliding protection ring interposable between the presser and the base. The protection ring includes a first surface facing towards and configured to contact the presser and a second opposing surface facing towards the base. The second surface has a sliding friction coefficient greater than a sliding friction coefficient of the first surface.

A siding tool for siding installation in building construction to efficiently measure the distance between adjacent siding panels and to install siding. The body of the siding tool is preferably approximately 3/16 ( 3/16 inches) wide, and a depth of approximately two inches (2). The width and depth are used to measure distances according to building code. The body has a lip at one end that extends from the base of the body. The lip is configured to position the siding tool in place by catching the bottom edge of a panel of siding that has been placed. The lip of the siding tool is also configured for a user to position the siding tool upside down and use the lip to draw measurement lines.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers, and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket, an insertion block, and pushing and clamping pliers, wherein the ceramic tile leveling bracket is disposed at a junction of at least two adjacent ceramic tiles, one end of the insertion block is inserted into an insertion block receiving portion of the ceramic tile leveling bracket, and the pushing and clamping pliers push and clamp the insertion block into a ceramic tile leveling bracket such that a bottom face of the insertion block is tangent to upper surfaces of the ceramic tiles. The ceramic tile leveling and laying system is easy to operate, and improves the laying efficiency and laying quality.

A tile levelling device (10) includes a base portion (12) having an upper surface (14) and an opposing lower surface (16), the lower surface (16) being substantially planar; two stems (20) each having a proximal end frangibly connected to the base portion (120) and a distal end connected to a body (32), a generally rectangular hole (34) being defined by the stems (20) the base portion upper surface (14) and the body (32), the hole (34) being adapted to receive a wedge (50); and a stiffening formation (70) located at or near the interface between each stem (20) and the body (32).

A device for levelling tiles includes a traction member having a base which can be inserted below two or more of the tiles which are adjacent at mutual edges, and a C-shaped element extending from the base, the free ends of its wings being associated with the base. The device further includes a wedge having a surface with a serrated profile for interaction with the traction member at an edge of the core of the C-shaped element. The wedge is insertable inside the C-shaped element of the traction member between the wings thereof.

A wall construction system includes multiple block types that interfit with one another to form walls in a staggered arrangement. Block types include jamb blocks having front and back surfaces, a planar surface on a first end, and a second side having a projecting surface or a receiving surface configured to mate with the projecting surface. The jamb block includes a top mating surface and a bottom mating surface configured to mate with the top mating surface. Webs extend from the front surface to the back surface to form voids. A multi-directional elevation is formed over a void adjacent the planar surface to permit stacking of blocks in two orientations. Other block types include a half jamb block having a web to form a void and a planar surface, and a web stretcher having a projecting surface on one end and a receiving surface on another end.

For leveling tiles, a tile leveler includes a base, a plurality of joint spacers, and two or more break lines. The brake lines are formed in the base along planar axes. Each joint spacer is within a subdivision distance of a break line. Each joint spacer adjacent to a given break line is on a spacer side of the given break line, and the break lines divide the base into sections.

For leveling tile, a tile leveling device (100) includes a tower (105), a base (120), and leveling ridges (130). The tower (105) includes a cross piece (110) and at least one strut that extends (115) in a distal direction (150) along a first axis (145) from the cross piece (110). Each strut (115) has a first traverse width (170). The base (120) is connected to the at least one strut (115) at a base intersection (140) and extends transversely from the at least one strut (115). The cross piece (110), the at least one strut (115), and the base (120) form a tension gap (125). The leveling ridges (130) are disposed on a proximal surface (121) of the base (120). Each leveling ridge (130) comprises a distal ridge side (131) connected to the base and a proximal ridge surface (132).
