Description:
A MOLD ASSEMBLY FOR PRODUCING CONCRETE SPACERS

TECHNICAL FIELD

[0001] The present disclosure relates to construction accessories, particularly to concrete spacers. More particularly, the present disclosure relates to molds for producing concrete spacers and methods for producing the same.

BACKGROUND

[0002] A rebar spacer is a device that secures the reinforcing steel or "rebar" in reinforced concrete structures. Specifically, a spacer is utilized to make enough coverage when the rebar is assembled in place, prior to the final concrete pour. The spacers are left in place for the pour and become a permanent part of the structure. Rebar spacers may be made of concrete, plastic, or steel. Plastic spacers are the most popular due to much lower prices, being lightweight and easily transportable, and more flexibility.

[0003] However, utilizing plastic spacers may have some issues. For example, due to the difference between plastic and concrete, moisture and destructive ions may penetrate into the concrete, which may cause an increase in rebar corrosion rate. Consequently, structure lifespan may significantly decrease. Furthermore, due to the different between thermal expansion coefficient of plastic and concrete, cracks in the border between spacer and concrete may expand. In addition, plastic spacers may have other issues, such as lower thermal conductivity and less pressure resistance compared to concrete spacers.

[0004] Concrete spacers that are being manufactured are expensive and their transportation is difficult due to their higher weight and fragility. There is, therefore, a need for a system and method that may allow for in situ production of concrete spacers at a lower cost. There is further a need for a system and method that may allow for utilizing the surplus mortar of different parts of construction process for in situ production of concrete spacers to prevent wasting the excess mortar.

[0057] FIG. 6 illustrates a front view of a transverse partitioning sheet 600, consistent with one or more exemplary embodiments of the present disclosure. In an exemplary embodiment, transverse partitioning sheet 600 may be structurally similar to transverse partitioning sheets 116. In an exemplary embodiment, transverse partitioning sheet 600 may include a plastic hollow profile sheet or a plastic twin wall sheet extended along transverse axis 402. In an exemplary embodiment, transverse partitioning sheet 600 may extend upward from a base sheet, such as base sheet 200 between a lower edge 604 of transverse partitioning sheet 600 and an upper edge 602 of transverse partitioning sheet 600. In an exemplary embodiment, transverse partitioning sheet 600 may further include a plurality of coupling slots 606 that may be formed on lower edge 604 of transverse partitioning sheet 600. In an exemplary embodiment, plurality of coupling slots 606 may be arranged in an array extended along transverse axis 402, where each coupling slot of plurality of coupling slots 606 may be cut into lower edge 604 of transverse partitioning sheet 600 along an axis perpendicular to transverse axis 402. In an exemplary embodiment, plurality of coupling slots 606 may be equally spaced apart.

[0058] In an exemplary embodiment, transverse partitioning sheet 600 may further include a pair of hangers (608a, 608ft) on extreme ends of transverse partitioning sheet 600 spaced apart along transverse axis 402. In an exemplary embodiment, each hanger of pair of hangers (608a, 608ft) may be configured to be receivable within a corresponding slot of a plurality of slots of a longitudinal outer sheet. For example, hanger 608a may be configured to be receivable within a corresponding slot of plurality of slots 306 of longitudinal outer sheet 300. In an exemplary embodiment, transverse partitioning sheet 600 may be transversely mounted between two longitudinal outer sheets, such as longitudinal outer sheets (104a, 104ft), where each hanger of pair of hangers (608a, 608ft) may be configured to be coupled to a corresponding slot of each longitudinal outer sheet of longitudinal outer sheets (104a, 104ft). In an exemplary embodiment, each hanger of pair of hangers (608a, 608ft) may include an L-shaped member forming a hanger slit that may be coupled to a corresponding slot of plurality of slots 306. For example, hanger 608a may include a first L-shaped member 611a forming a first hanger slit 610a and hanger 6086 may include a second L-shaped member 611/> forming a second hanger slit 610/>.

Such mounting may be carried out by hanging corresponding hangers of each transverse partitioning sheet of nine transverse partitioning sheets 116 within corresponding eight slots of longitudinal outer sheets (104a, 1046).

[0060] In exemplary embodiments, such arrangements of outer wall sheets and inner partitioning sheets of an exemplary mold assembly may allow for outer wall sheets to be easily mounted on an exemplary base sheet and then inner partitioning sheets to be fitted between outer wall sheets to create sub-molds. Corresponding holes within exemplary longitudinal outer walls and exemplary longitudinal partitioning sheets may allow for inserting exemplary plastic straws into sub-molds to create holes within produced concrete spacers, which may later be utilized for fastening exemplary concrete spacers with wires. In addition, semi-cylindrical recessed portions may be formed on produced concrete spacers by utilizing semi-cylindrical bulges on an exemplary base sheet of an exemplary mold.

[0061] In an exemplary embodiment, simple shape and assembly procedure of an exemplary mold assembly may allow for construction workers to easily assemble an exemplary mold assembly at a construction site. Since molding is to be carried out at the construction site, there may be access to excess mortar from construction. Consequently, excess mortar may be utilized for forming concrete spacers, thereby reducing production costs and waste.
