摘要： The present disclosure relates to a slab bolster upper for supporting rebars in a reinforced concrete structure. The slab bolster upper comprises an elongated base defining a lower surface, an upper surface for supporting the rebars, a first edge and a second edge opposite the first edge, voids formed through the elongated base to facilitate free flow of concrete therethrough and around the elongated base, a first connexion integrally formed about the first edge of the elongated base and a second connexion integrally formed about the second edge of the elongated base. The first and second connexions are configured to securely engage with corresponding first and second connexions of adjacent slab bolster uppers for interconnecting a plurality of slab bolster uppers together.

摘要： This rebar chair has a body with four legs between which there are defined two intersecting passages for simultaneously receiving the intersecting portions of two rebars normal to each other. The rebars are suspended by a fastening wire or supported by an auxiliary chair below said body. The legs forming one of the passages have a uniform spacing and are adapted to closely straddle the rebar extending through the same. The legs of the second passage flare downwardly so that their spacing progressively increases from the body to the free ends from a spacing smaller than to a spacing greater than the uniform spacing between the legs of the first passage. The chair is positively located and stabilized by the intersecting rebars. A saddle is formed on the top of the body for simultaneously supporting a third rebar. The spacing between the faces of the legs forming a first passage is uniform from the body to the free ends of the legs while the spacing between the faces of the legs forming the other right angle passage increases from the body to the free ends of the legs in such a manner that depending on the orientation of the chair with respect to the rebars the same can be positioned at two adjusted distances from the bottom of the concrete form.

摘要翻译： 该钢筋椅具有一个具有四条腿的主体，在该主体之间限定了两个相交的通道，用于同时接收彼此正常的两个钢筋的相交部分。 钢筋由紧固线悬挂或由辅助椅子支撑在所述主体下面。 形成其中一个通道的腿具有均匀的间隔，并且适于紧密地跨越延伸穿过其的钢筋。 第二通道的腿向下张开，使得它们的间隔从小于距第一通道的腿部之间的均匀间隔的间隔小的距离从身体逐渐增加到自由端。 椅子由相交的钢筋定位稳定。 鞍座形成在身体的顶部，用于同时支撑第三个钢筋。 形成第一通道的腿的面之间的间隔从身体到腿的自由端是均匀的，而形成另一个直角通道的腿的面之间的间隔从腿部的腿部自由端增加 以这样的方式，取决于椅子相对于钢筋的定向，它们可以位于距离混凝土形式的底部两个调整的距离处。

摘要： A wheel spacer is provided for spacing a reinforcing rod for a cementitious structure away from an object during fabrication of the structure. The spacer consists of two substantially semicircular sections configured for connection together with the rod abuttingly retained in saddles generally situated at the center of the sections when connected together in an assembled configuration for the spacer. Each section has, on an inner wall thereof in which the saddles are situated, primary inserting arms for insertion into apertures for locking engagement with teeth on the inserting arms with teeth on receiving arms of the other section. Retaining arms having guide walls further facilitate retention of the rod and guiding thereof towards the saddles while the spacer is placed in the assembled configuration.

摘要： The present disclosure relates to a chair for supporting rebars above a surface in a reinforced concrete structure. The chair comprises a support structure which includes a rebar supporting area for receiving the rebars, a first leg and a second leg. The chair further comprises first and second base members which are adapted to engage with the first and the second leg ends. Therefore, when the first leg end and the second leg end are securely engaged with respectively the first base member and the second base member, the support structure is supported above the surface by the first base member and the second base member such as to receive rebars. Accordingly, concrete may be poured around the chairs positioned on the surface and further around the rebars that are supported by them.

摘要： A rebar support system used in the reinforcement of concrete structures is disclosed, comprising a rebar support tower and a rebar support base, individually capable of holding rebar members at a predefined height within a range of possible heights, the two further capable of acting together in tower-base duplex fashion in the formation of multilevel rebar grids. The rebar tower has four legs between which there are defined two intersecting passages, the legs being open-ended at the bottom and forming bidirectional arches at the top of said intersecting passages, said rebar tower further having a saddle foil cation at its apex. The rebar tower provides a tapered and angled foot profile at the bottom of each leg to minimize the area of contact when used with a concrete form, thereby reducing rebar support footprints after form removal. The rebar base comprises a platform with centrally rising bidirectional saddle formations, the intersecting passages and saddle formations of tower and base providing means for receiving the intersecting segments of rebars which are normal to each other. Locking insert hooks and guide tabs incorporated in the rebar base, and hook receptacles, guide ridges and restraining surfaces incorporated in the rebar tower provide complementary means for the attachment of the two structures to form a rigid, yet detachable tower-base assembly in multiple rebar grid configurations. The rebar base provides a stable support means when used individually or in tower-base assemblies on granular surfaces, such as sand or gravel beds.

摘要： A cage spacer for spacing a reinforcement structure apart at a predefined distance from a forming surface of a forming structure for a cementitious structure during formation of the cementitious structure therein has a bracket and a roller wheel, both constructed of a plastic material. The bracket has an attachment face and a generally opposed roller face and is connectable to the reinforcement structure with the attachment face abutting thereagainst. The roller wheel is rotatably and removably mounted in the bracket with an outer circumferential surface thereof extending from within the bracket partially beyond the roller face. The roller wheel is sized and positioned relative the attachment face for abutting and rolling of the outer circumferential surface against the forming surface at the predefined distance from the reinforcement structure, thereby spacing the reinforcement structure apart from the forming surface at the predefined distance.
