Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door structure, and particularly relates to a graphite door core plate. BACKGROUND

[0002] An indoor door comprises a door frame, a door core and a door panel, wherein the door core serves as a main functional component and bears the functions and effects of structural strength, fireproofness, moisture resistance, sound insulation and warmth retention of the door body, and most of the door cores on the market adopt a bridge-hole type wood plate structure, which can reduce the material usage and improve the thermal insulation performance, and the wood core plate has good processing performance.

[0003] In order to pursue better quality, graphite homogeneous plates commonly used for external wall thermal insulation are gradually applied to the door core, the graphite homogeneous plate has good thermal insulation, moisture resistance, sound insulation and fire resistance, and the graphite homogeneous plate is more environmentally friendly than wood, and is considered to be a high-quality alternative material to the wood bridge-hole plate. However, the graphite homogeneous plate with high strength has a larger density than wood, and if the foaming rate is increased, the strength of the graphite homogeneous plate will be greatly reduced, and the graphite homogeneous plate has poor processing performance and cannot be connected with the door frame and the door panel through bolts and other connecting pieces.

[0004] Therefore, how to provide a graphite door core plate that is easy to assemble has become a technical problem to be solved at present. SUMMARY

[0005] Therefore, the present application provides a graphite door core plate, which aims to improve the assembly convenience between the graphite door core plate and the door frame and the door panel without affecting the thermal insulation, moisture resistance and sound insulation performance brought by the graphite homogeneous plate.

[0006] The technical scheme of the present application is as follows: the present application provides a graphite door core plate, which can provide a connection site compared with a conventional graphite door core plate, so as to better fix and connect the door frame and the panel, specifically, the graphite door core plate comprises a graphite homogeneous plate and a framework, the graphite homogeneous plate is a rectangular plate, the framework is embedded on the inner side of the graphite homogeneous plate along the diagonal line, and the framework is in communication with the side surface of the graphite homogeneous plate near the four corners of the graphite homogeneous plate.

[0007] In some embodiments, the framework comprises two fixed rods, a tenon groove is formed in the middle of one of the fixed rods in the radial direction, and a tenon is formed on the middle of the other fixed rod and protrudes outward in the radial direction, the tenon is embedded in the tenon groove, and the two fixed rods are tightly connected.

[0008] In some embodiments, the middle part of each of the two fixing rods is provided with a groove, and the mortise and the tenon are arranged in the groove. When the two fixing rods are fastened, the two grooves are embedded with each other. By arranging the groove, the overall thickness of the embedded position of the two fixing rods can be consistent with the thickness of the fixing rod, thereby reducing the overall thickness of the two fixing rods after connection.

[0009] In some embodiments, a rib plate is further included, and at least one rib plate is arranged on the surface of each fixing rod in a protruding manner. The plane of the rib plate is perpendicular to the straight line direction of the fixing rod on which the rib plate is installed.

[0010] The rib plate can increase the contact area between the fixing rod and the graphite homogeneous plate, thereby improving the connection strength therebetween.

[0011] In some embodiments, at least one clamping groove is arranged on the surface of the fixing rod along the length direction, and the rib plate is arranged in the clamping groove in an embedded manner.

[0012] By clamping, the installation position and the number of the rib plate can be changed to adapt to different door plate installation requirements.

[0013] In some embodiments, a fixing wire is further included, and the end part of the fixing rod provided with the mortise is fastened with the end part of the fixing rod provided with the tenon through the fixing wire.

[0014] In the above embodiments, since the two fixing rods are connected through the middle part, when the end part of the fixing rod is stressed, the torque generated under the action of the lever is relatively large on the action force of the connection position of the middle part of the fixing rod, and the connection structure of the middle part is easily damaged. Therefore, the end part of the cross-connected fixing rod is sequentially connected through the fixing wire, so as to reduce the action force conducted to the connection point of the middle part of the fixing rod, bear part of the action force through the fixing wire, thereby improving the structural stability of the fixing rod.

[0015] In some embodiments, the fixing wire can be a chemical fiber wire, a carbon fiber, a glass fiber or a metal wire.

[0016] In some embodiments, a limiting sleeve is further included, and the limiting sleeve is sleeved outside the mortise joint of the two fixing rods.

[0017] The limiting sleeve can be a metal piece or a high polymer structural piece. By coating the outside of the mortise joint of the fixing rod, the structural strength is provided, and the limiting sleeve also has a certain shaping effect. During the installation of the fixing wire, the end part of the fixing rod is prevented from being deformed, so as to affect the structural cooperation of the graphite homogeneous plate in the later period and the normal use of the door plate.

[0018] In some embodiments, a first connecting protrusion and a second connecting protrusion are arranged on the side surface of the fixing rod in a protruding manner, and the side surface of the fixing rod away from the first connecting protrusion and the side surface of the fixing rod away from the second connecting protrusion are respectively communicated with the two side surfaces of the graphite homogeneous plate.

[0019] In some embodiments, the end of the fixed rod is in communication with two adjacent side surfaces of the graphite homogeneous plate.

[0020] The surface where the end of the fixed rod is in communication with the side surface of the graphite homogeneous plate is used to provide a fixed connection point of the door frame, for example, a bolt hole is formed on the surface where the fixed rod is in communication with the side surface of the graphite homogeneous plate, or the door frame and the fixed rod are directly connected through a fastening connector, for example, a nail is used for connection.

[0021] The graphite door core plate of the present application has the following beneficial effects compared with the prior art:

[0022] The present application provides a graphite door core plate, which can use a graphite homogeneous plate with a higher foaming rate compared with a conventional integrated graphite homogeneous plate, and the door core plate has high structural strength under the support of the skeleton structure. In addition, the skeleton structure provides connection sites, which can overcome the problem that the conventional graphite homogeneous plate can only be connected with the door plate and the frame through an adhesive, and the door plate and the frame can be connected through a connector such as a bolt or a nail provided on the connection sites, thereby improving the assembly performance and the stability of the connection of the graphite door core plate with the door plate and the frame, avoiding the use of a large amount of glue, and improving the environmental protection performance.
