Abstract

DC60 (09/12/57) This invention is a prefabricated wall panel with tongue and groove joints. The high precision of the tongue and grooves allows for easy and convenient installation, both vertically and horizontally. The grooves are pre-aligned for seamless assembly, eliminating the need for joint filler. The prefabricated wall panel consists of three layers: an outer layer of fiber cement and a core of foam cement. It is lightweight, easy to manufacture, and possesses all the necessary wall performance characteristics. This invention is a prefabricated wall panel with tongue and groove joints.

Revised 04/08/2015 1. Prefabricated walls assembled using tongue and groove systems consist of three layers. The outermost layers on both sides are fiber cement panels, and the middle layer is a cement-foam mixture composed of cement, sand, water, and polystyrene foam. A unique feature is the tongue and groove system. Along the width, a tongue is located opposite the groove, and along the length, another tongue is located opposite the groove. This allows for assembly with other prefabricated walls on the sides, top, or bottom by inserting the tongue of one panel into the groove of another, either sideways or vertically, using cement adhesive for bonding. These tongue and groove prefabricated walls have a height of 2,400-2,800 millimeters, a thickness of 75-100 millimeters, and a weight of 65-110 kilograms. The size and design of the tongue and groove are engineered to ensure a precise fit according to construction standards, achieving a height equivalent to one story and a weight that can be manually lifted without the need for machinery. 1. The work is to facilitate construction in areas without machinery. 2. The prefabricated wall is assembled using tongue and groove according to claim 1, where the fiber cement sheet, with the optimal thickness of 4 mm in this invention, is composed primarily of Portland cement and cellulose fibers to achieve expansion when immersed in water, and resistance to leakage, water absorption, thermal conductivity, sound insulation, and fire resistance that meet international standards and are suitable for the application. 3. The prefabricated wall is assembled using tongue and groove according to claim 1, where the cement-foamed layer has pores with a diameter of 1-2 mm to prevent water penetration and help distribute moisture. 4. The production of a prefabricated wall assembled using tongue and groove consisting of a three-layer structure, with the outermost two layers being fiber cement sheets and the middle layer being a cement-foamed structure composed of cement, sand, water, and polystyrene foam, with the following manufacturing process: a. Preparation of a concrete formwork with tongue and groove around the perimeter, with a tongue on the opposite side along the width. A. Installation on the formwork base: Place the fiber cement sheets on both sides, opposite each other, of the formwork, leaving a gap in the middle for filling with the foam cement mixture. B. Pour the foam cement mixture into the formwork. C. Allow the foam cement mixture to harden for 10-16 hours. The optimal hardening time is 14 hours. D. Remove the formwork once the foam cement mixture has fully hardened. This will result in a prefabricated wall panel assembled using a tongue and groove system, with the groove design varying depending on the specifications. Wrap the wall panel in plastic on all sides for curing for 10-20 days. The optimal curing time is 15 days. ------------------------------------------------------------------------------------------ 1. The prefabricated wall consists of three layers. The outermost layers on both sides are fiber cement sheets, and the middle layer is a foam cement mixture composed of cement, sand, water, and polystyrene foam. Its unique feature is the tongue and groove system on all four sides. One side of the inner surface can be either a tongue and groove or a groove, depending on the application, to facilitate the assembly of various prefabricated wall configurations. (Edited 09/12/2014) 1. Prefabricated walls assembled using tongue and groove systems consist of three layers. The outermost layers on both sides are fiber cement sheets, and the middle layer is a cement-foam mixture composed of cement, sand, water, and polystyrene foam. Its unique feature is the tongue and groove system. Along the width, there is a tongue opposite the groove, and along the length, there is a tongue opposite the groove, for easy assembly with other wall panels. The tongue of one panel is inserted into the groove of another panel, either sideways or vertically, using cement adhesive or other bonding materials to simplify the assembly process. These prefabricated walls, assembled using tongue and groove joints, have a height of 2,400-2,800 millimeters, a thickness of 75-100 millimeters, and weigh 65-110 kilograms. The size and design of the tongue and groove joints are arranged to ensure a perfect fit according to construction standards, equivalent to a single story in height, and with a weight that can be manually lifted without the need for machinery, making construction convenient in areas without machinery. (Revised 4/8/58) 1. Prefabricated interlocking walls consist of three layers. The outermost layers on both sides are fiber cement panels, and the middle layer is a cement-foam composite made from cement, sand, water, and polystyrene foam. A unique feature is the tongue and groove system. Along the width, a tongue is located opposite the groove, and along the length, another tongue is located opposite the groove. This allows for precise assembly with adjacent prefabricated walls by inserting the tongue of one panel into the groove of another, either horizontally or vertically, using cement adhesive for bonding. These interlocking prefabricated walls have a height of 2,400-2,800 millimeters, a thickness of 75-100 millimeters, and weigh 65-110 kilograms. The size and design of the tongue and groove are optimized for precise assembly to meet construction standards, achieving a height equivalent to one story and a weight that can be manually lifted without machinery, making construction convenient in areas without advanced equipment. 2. Prefabricated interlocking wall panels as per claim 1, whereby the optimal thickness of the fiber cement panel in this invention is 4 mm, composed primarily of Portland cement and cellulose fibers, to achieve expansion when immersed in water, and resistance to leakage, water absorption, thermal conductivity, sound insulation, and fire resistance that meet international standards and perform appropriately for the intended application. 3. Prefabricated walls assembled using tongue and groove joints as per claim 1, where the foamed cement layer has pores with a diameter of 1-2 millimeters to prevent water penetration and help distribute moisture. 4. Production of prefabricated interlocking wall panels consisting of a three-layer structure. The outermost layers on both sides are fiber cement sheets, and the middle layer is a cement-foam mixture composed of cement, sand, water, and polystyrene foam. The manufacturing process involves the following steps: a. Preparing a concrete formwork with tongue and groove joints around the perimeter. The tongue is located opposite the groove along the width and lengthwise sides. b. Installing the formwork by placing the fiber cement sheets on opposite sides of the formwork, leaving a gap in the center for filling with the cement-foam mixture. c. Pouring the cement-foam mixture into the formwork. d. Allowing the cement-foam mixture to harden for 10-16 hours. The optimal hardening time is 14 hours. e. Removing the formwork once the cement-foam mixture has fully hardened. The resulting prefabricated wall panel is assembled using a tongue and groove system, with the groove spacing depending on the design. The wall panel is then wrapped in plastic on all sides. To cure the wall panels, a curing period of 10-20 days is required; the optimal curing period is 15 days.
