Description

Technical Field

[0001] This invention relates to a connector assembly for connecting multiple templates used in beam-slab construction. Specifically, the connector assembly includes at least one beam arch clamp connector and at least one plate clamp connector for securing one beam template to another. Background Technology

[0002] When providing a foundation or subgrade for laying concrete, formwork serves as a temporary mold for forming concrete structures in the construction industry. The formwork molds or holds the newly poured concrete into the desired shape for the building's structure. The formwork is then removed after the concrete has hardened.

[0003] Formwork is typically constructed using timber or plywood. Traditional types of formwork are flexible and suitable for low-cost construction. However, traditional formwork is not durable and has a high turnover rate. The use of timber has created various problems in formwork used for beam structures. Metal formwork made of steel or aluminum is reusable and can last a long time. However, metal formwork is much heavier than conventional formwork and may require a crane to lift it into place. Therefore, further research and development are ongoing to determine the optimal material for better use as environmentally friendly and more efficient formwork. One promising type of formwork is plastic formwork, which is considered more environmentally friendly, highly efficient, and offered for simple purposes. Plastic formwork is gaining popularity in the construction industry. Formwork made of engineering plastic materials is often prefabricated in a variety of sizes, making it customizable and easy to assemble quickly. Plastic formwork is also the most sustainable alternative to traditional formwork because concrete is easily washed away after removal from the formwork, allowing it to be reused more than 100 times. For formwork construction, plastic formwork is considered a superior option to traditional formwork due to its lightweight, durability, and reusability.

[0004] The inventors invented a plastic formwork in International Patent Publication No. WO 2008060138A (hereinafter referred to as WO 138A Publication) and have been granted patents in several jurisdictions under Patent No. MY 166995A. WO 138A discloses a system of formwork and connecting devices for forming concrete structures. The formwork panels, particularly plastic formwork, are designed with multiple ribs and multiple holes on the sides of the panels. As disclosed in WO 138A Publication, they can also be connected adjacent to each other, thereby enabling the formation of various building components such as walls, columns, and beams from concrete. To maximize the versatility of the plastic formwork, the need for vertical connections between panels has become apparent and desirable. Although the formwork itself forms the most visible part of the structure's construction, the connecting units or devices are equally important as they are used to hold and secure the formwork in place for pouring concrete. Therefore, connectors with optimal design and materials are important for the good functioning of the plastic formwork in the construction.

[0005] Currently, even connectors used for plastic formwork are made of aluminum or wood. To secure beam formwork, the connectors must also be nailed in place to further hold the formwork in place. Furthermore, when wood is used as a connector, the poured concrete can adhere to the wood due to the combination of the liquid properties of concrete and the wood's ability to absorb liquid materials. This results in high moisture content in the wood and can also lead to shrinkage and cupping of wet concrete, resulting in open joints and leaks within the formwork system. Moreover, wood reuse is limited to approximately five to six rounds until it is deemed unfeasible. With aluminum, a common problem is the inability to cut aluminum to the required dimensions according to the formwork connection and orientation. This makes holding the formwork more time-consuming and less efficient compared to prefabricated connectors that can be used for any connection and orientation of formwork components. Many connectors or connection devices have been applied and invented in the construction industry for connecting formwork panels or beams.

[0006] Chinese Patent Application No. CN 208310202 U discloses an example of a connector or connecting device, hereinafter referred to as Patent CN 202U, entitled "A Beam Bottom Corner Template," filed on April 26, 2018; Applicant: Shenzhen Guangshengda Construction Co., Ltd. Patent CN 202U relates to a beam connector with an L-shaped infill plate that connects one panel to another, particularly for facilitating the installation of a clothes rack onto a beam. The L-shaped infill plate is part of a beam corner template used as a connector. The L-shaped infill plate is made of plastic and is attached to the panels by adhesive that bonds them together.

[0007] Another example of a connector or connecting device is disclosed in Chinese Patent Application No. CN208072962 U, hereinafter referred to as Patent CN 962U, entitled "A Beam-Slab Arch," filed on February 2, 2018, by Jiangsu Lixin New Building Formwork Co., Ltd. Patent CN 962U discloses an L-shaped plate body used as a connector for connecting a beam arch panel to a wall panel. Patent CN 962U discloses a telescopic plate body having a sliding groove for adjusting the plate body according to the length of the beam arch. The beam arch and the wall panel are preferably secured to the plate body by pins for connecting multiple beam arches in the horizontal direction. The plate body includes a telescopic structure that slides on the sliding groove for adjusting the beam length. The telescopic structure includes two insert plates for inserting into each other into an insertion groove. Furthermore, the plate body includes a snap-fit ​​groove for clamping the edge of the panel.

[0008] Another example of a connector or connecting device is disclosed in Dutch Patent No. NL 1025505 C2, hereinafter referred to as "NL 505C2 Patent," entitled "Connecting Structure comprising at least two contours and connecting parts connected to one contour by a permanent connection (e.g., plastic deformation) and to the other contour by a snap-fit ​​connection," filed on February 17, 2004, by Alcoa Netherlands. NL 505C2 Patent discloses a connecting device that connects via a snap-fit ​​connection. This connecting device permanently connects at least two contours to one contour. The contour has a cavity in which the connecting device is inserted or received. NL 505C2 Patent generally relates to a window structure comprising four mutually configured contours connected by a connecting device. The connecting device is secured to the contours by a click element to hold each contour in place when connected to another contour.

[0009] Another example of a connector or connecting device is disclosed in Canadian Patent No. CA 2574964 A1, hereinafter referred to as "CA 964A1 Patent," entitled "Double-Ended Connector," filed on January 19, 2007, by Ideas Without Borders Inc., CA. CA 964A1 Patent discloses a block-shaped device for connecting insulating panels of insulated concrete formwork, the block-shaped device comprising male interconnecting devices and female interconnecting devices. Each insulating panel has opposing edges, wherein a male interconnecting device is present on a first edge and a female interconnecting device is present on a second edge. CA 964A1 Patent discloses that the insulating panels are formed of a malleable material, such as polystyrene. The interconnecting devices are distinct from each other. The male interconnecting device includes a protrusion and a bridging element, while the female interconnecting device includes a recess and a groove. The recess and groove are sized to receive the protrusion having the dimensions of the protrusion with the male interconnecting device. The positioning of the male and female interconnecting devices at each end enables a vertical connection of the insulating panels.

[0010] As mentioned above, various connectors or connection devices for connecting beam formwork have been developed; however, the prior art does not disclose a connector or connection device capable of connecting plastic formwork through a simple and effective locking joint mechanism. Therefore, there is a need for an improved connector that is easy to use, reusable, and cost-effective in the construction of beam formwork. Summary of the Invention
