Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of door core plates, and particularly relates to a gypsum door core plate. Background Art
[0002] A door core plate is a material used to fill the inside of a door, aiming to improve the sound insulation, heat insulation and overall structural strength of the door. There are many types of door core plates, which can be divided into various types according to different materials and uses, including solid wood boards, plywood boards, decorative panels, blockboards, particle boards, density boards, fireproof boards, etc. Each door core plate has its unique physical and chemical properties and is suitable for different environments and needs.
[0003] A gypsum door core plate refers to the filling material in the door core material.
[0004] The inventor found that the existing gypsum door core plates are all solid, resulting in an overly heavy overall weight, high cost, and poor strength.
[0005] Therefore, research and improvement are carried out on the existing structure and deficiencies to provide a gypsum door core plate, with the expectation of achieving a more practical value purpose. Summary of the Utility Model
[0006] Aiming at at least one problem in the prior art, an object of the utility model is to provide a gypsum door core plate.
[0007] To achieve the above object, the utility model adopts the following technical solutions to implement:
[0008] A gypsum door core plate includes a door core plate main body. The door core plate main body is a gypsum board, and there are a plurality of through horizontal holes on the door core plate. A framework net plate is symmetrically arranged inside the door core plate main body, and a connecting fixed rod is arranged between adjacent framework net plates.
[0009] Preferably, a hollow cavity is arranged inside the fixed rod, and a flame retardant liquid is stored inside the fixed rod.
[0010] Preferably, a connecting pipe is arranged between the upper and lower adjacent fixed rods and is communicated. A water injection pipe is arranged inside the door core plate main body at the upper end, and the water injection pipe is communicated with the fixed rod.
[0011] Preferably, a liquid outlet is arranged at one end of the hollow cavity, and a detachable sealing plug is arranged inside the liquid outlet. The gypsum door core plate outside the sealing plug is porous.
[0012] Preferably, a telescopic rod fixedly connected and used for pushing open the sealing plug is arranged inside the hollow cavity, and an expansion packet that expands when heated is arranged inside the telescopic rod.
[0013] Compared with the prior art, the utility model has the following technical effects:
[0014] Thermal insulation: The core of the gypsum door core board is composed of tiny air holes. Since the thermal conductivity of air is very small, it has good lightweight thermal insulation performance.
[0015] Good fire resistance: Since gypsum belongs to Class A non-combustible materials, and a large amount of heat will be absorbed during the process of releasing combined water when encountering fire, delaying the increase of the surrounding environmental temperature. Therefore, the gypsum door core board has good fireproof and flame-retardant performance.
[0016] Good sound insulation performance: Gypsum itself has a sound insulation effect. The door core board has a unique cavity structure and has good sound insulation performance.
[0017] The gypsum door core board can be combined with the external wooden or metal door frame to form a door with fireproof and sound insulation functions.
[0018] The design of the skeleton grid board and the fixing rod can effectively improve the overall strength of the gypsum door core board. The design of multiple transverse holes in the gypsum door core board can effectively reduce the cost, reduce the overall weight of the gypsum door core board, and facilitate transportation. The combination of the skeleton grid board and the fixing rod with the transverse holes not only reduces the weight of the gypsum door core board, but also ensures the overall strength, and even improves the strength.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be another intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific implementation manners and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0029] Example 1, please refer to Figure 1 、 Figure 2 , a gypsum door core board, including the main body 1 of the door core board. The main body 1 of the door core board is a gypsum board, and a plurality of through horizontal holes 11 are provided on the door core board. Symmetrically distributed skeleton mesh boards 12 are arranged inside the main body 1 of the door core board, and connecting fixed rods 13 are provided between adjacent skeleton mesh boards 12.
[0030] Please refer to Figure 3 , as a feasible implementation manner, a hollow cavity is provided inside the fixed rod 13, and a flame retardant liquid is stored inside the fixed rod 13.
[0031] The fixed rod 13 is designed to be hollow and store the flame retardant liquid, which can further improve the overall fire resistance performance.
[0032] In this embodiment, a connecting pipe 16 communicating with each other is provided between the upper and lower adjacent fixing rods 13. A water injection pipe 14 is provided in the door core board main body 1 at the upper end, and the water injection pipe 14 is communicated with the fixing rod 13.
[0033] The design of the connecting pipe 16 and the water injection pipe 14 enables the flame retardant liquid to be injected through the water injection pipe 14 after the gypsum door core board is installed. Such a design can not only keep the weight of the gypsum door core board light during transportation, but also facilitate ensuring the overall flame retardant performance of the gypsum door core board during use.
[0034] In this embodiment, a liquid outlet is provided at one end of the hollow cavity, and a detachable sealing plug 15 is provided in the liquid outlet. The gypsum door core board outside the sealing plug 15 is porous.
[0035] The detachable sealing plug 15 and the porous gypsum door core board outside the sealing plug 15 cooperate to enable the flame retardant liquid to flow out through the liquid outlet and the holes after the gypsum door core board encounters a set temperature by opening the sealing plug 15, and further realize the flame retardance of the outside of the gypsum door core board by using the flame retardant liquid, thereby improving the flame retardant effect.
[0036] In this embodiment, a telescopic rod 17 fixedly connected and used to push open the sealing plug 15 is provided in the hollow cavity, and an expansion packet 18 that expands when heated is provided in the telescopic rod 17.
[0037] The design of the telescopic rod 17 and the expansion packet 18 enables the expansion packet 18 to automatically expand after the gypsum door core board encounters a set temperature, thereby automatically controlling the telescopic rod 17 to extend and push open the sealing plug 15, so that the flame retardant liquid can flow out and be laid on the outer surface of the gypsum door core board, further improving the flame retardance of the gypsum door core board.
[0038] It should be understood that the above description is for illustrative purposes rather than for limitation. By reading the above description, many embodiments and many applications other than the provided examples will be obvious to those skilled in the art.
