A clamp (51) for connecting panels in a surface coating structure on a base frame comprises a fixable element (100) and a rotatable element (200) having an upper part (220), projecting after its rotation from the fixable element (100) and provided with end (21, 22) of engagement in lateral grooves of adjacent panels. The rotatable element (200) has an intermediate part (280) and a lower part (290) which are constituted by two coaxial discs, the disc of the intermediate part (280) having a smaller diameter than the disc of the lower part (290). The fixable element (100) has two communicating coaxial holes (10, 11) housing the intermediate part (280) and the lower part (290) with a wide coupling to allow rotation of the rotatable element (200) with respect to the fixable element (100). A manufacturing process of the clamp (51) is also described.

The invention discloses a wooden floor with high utilization, a connection assembly, and a connection structure of a wooden floor with high utilization and a connection assembly. The wooden floor with high utilization includes a floor body. The floor body defines a first groove on one side surface thereof in a horizontal direction. The floor body defines a second groove on the other side surface thereof in the horizontal direction. The first groove and/or the second groove define a notch. The floor body of the present invention is merely required to define grooves on two sides thereof, and is not necessary to provide a protruding male buckle, as long as the first groove or the second groove is connected with a male buckle of the connection assembly, so that wood can be saved, thus increasing a utilization rate of the wood. The wood saved by a single piece of wood floor is limited, but many a little makes a mickle. Moreover, two adjacent floor bodies can be connected by the groove to reserve a certain gap therebetween according to need, which can increase the air permeability of the floor. The use of wood can be greatly saved to protect the ever-decreasing trees, and benefit the human society.

The present disclosure provides a paver lockdown system that prevents strong wind from uplifting pavers from pedestals installed on rooftops.

The invention relates to a deck connector for aligning adjacent decking members, such as deck boards, at a set distance from each other and for attaching the decking members to a support member, such as a joist.

The present disclosure provides a paver lockdown system that prevents strong wind from uplifting pavers from pedestals installed on rooftops.

A decking system including floor elements and a connecting system including a connecting device for connecting a first and a second floor element, wherein the connecting device is removably connectable to a support member. A first and a second connecting portion of the connecting device are configured to cooperate with a first and a second engagement portion, respectively, of the first and second floor elements for vertically connecting the first and second floor elements. The connecting device further includes a displaceable portion which is horizontally displaceable and is configured to assume a first and a second horizontal state, wherein a horizontal extension of the connecting device in the second horizontal state is smaller than a horizontal extension of thereof in the first horizontal state.

Disclosed herein is a clip for positioning and securing adjacent grooved planks to a joist. The clip includes a body and a pair of legs. The body extends longitudinally from a front end to a rear end and laterally between opposite lateral edges and defining a hole. Each leg of the pair of legs extends downward from the body at a longitudinal position between the front end and rear end. Each of the front end and the rear end includes a notch in the edge between the opposite lateral edges.

A hidden fastener and associated method for attaching decking members with side grooves to a support member includes a cross member and an elongate anchoring member. The cross member has a body with a front and rear end and defines a hole. The front end has at least one prong and the rear end includes a bent wing. At least one leg extends downward from the body intermediate the front and rear ends. Each of the front and rear ends are configured to engage with the groove of adjacent decking members. The front end is inserted into the groove of a leading decking member and the anchoring member is driven through the hole into the support member. A trailing decking member is placed with the rear end in the groove adjacent the leading decking member.

A bushing includes an upper collar with a lower sheath and an annular shoulder intermediate the collar and sheath. The collar has a plurality of spaced apart notches and the sheath has a plurality of spaced apart slits that may be circumferentially aligned with the notches. The sheath has a plurality of spaced apart ribs projecting outward circumferentially offset from the slit for assisting in maintaining the sheath within a hole in a fastener with the annular shoulder against the fastener. A securing member with an elongate shank extending from a head with a distal portion is maintained in the longitudinal opening in an upright position aligned with the hole. As the fastener is driven longitudinally through the opening and hole, force from the fastener causes the bushing to break away and yields direct contact between the securing member head against the top surface of the fastener.

In an exemplary embodiment, a hidden fastener may include a constraining member configured to support a plurality of boards, and a base member extending below the constraining member. The base member includes a pair of leg portions, each leg portion includes an opening at an inclined angle for receiving a fastener at an inclined position. The pair of leg portions is attached to a structural member via a spacing formed between the pair of leg portions, the spacing corresponding to a size of a top surface of a structural element.
