Abstract
Disclosed herein is a plate-shaped heating panel having connecting members fastened to each other by means of bolts and nuts. The heating panel comprises upper and lower plates integrally formed to face each other so as to form an inner fluid pathway in which heating water flows, a plurality of connecting members, each symmetrically extending from the upper and lower plates toward the lower and upper plates, respectively, and connecting the upper and lower plates to each other, the inner fluid pathway formed inside of the plate by means of the plurality of connecting members, and two fluid communication portions for supplying and discharging the heating water, wherein one or more connecting members adjacent to the fluid communication portions are punctured such that punctured portions of the connecting members are fastened to each other by means of bolts and nuts. Accordingly, a bonding strength of the heating panel is enhanced, and even though the crack is generated, the crack is forced to change in its progressing direction and is prevented from spreading, thereby enhancing the pressure resistance of the heating panel.
