Description

Technical Field

[0001] This utility model belongs to the field of fire door technology, and specifically relates to a fire door core panel that can be spliced. Background Technology

[0002] Fire-resistant door core panels are fire-resistant materials filled inside door frames, typically formed by casting and cooling multiple materials. Currently, these core panels only serve as partitions and do not provide cooling or fire extinguishing functions. To add cooling and fire extinguishing capabilities, water storage pipes can be installed inside the fire-resistant door core panel. However, since the core panel is cast as a single piece, it is not easy to cut out pipes, so splicing is required. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a splicable fireproof door core panel to solve the problems mentioned in the background art.

Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1

[0028] refer to Figures 1 to 5 The fireproof door core panel that can be spliced ​​according to this embodiment includes a first panel 1 and a second panel 2. Water pipes 3 are provided on the opposite surfaces of the first panel 1 and the second panel 2. The two sets of water pipes 3 are spliced ​​to form a complete pipe to accommodate water pipes. Water inlet 11 and water outlet 21 are respectively provided on the first panel 1 and the second panel 2. The water inlet 11 and the water outlet 21 are located at both ends of the water pipe 3. Multiple sets of fixing components 4 for splicing the two sets of panels are installed on the first panel 1 and the second panel 2.

[0029] Preferably, the inlet 11 faces outwards and the outlet 21 faces inwards.

[0030] Preferably, the fixing components 4 are in four groups and are respectively installed on the four corners of the first plate 1.

[0031] The fixing component 4 includes an insertion hole 41 penetrating the first plate 1 and the second plate 2 and two sets of stop hole 44. The two sets of stop hole 44 are located on both sides of the diameter of the insertion hole 41 and are connected to the insertion hole 41. Two sets of rotating holes 45 are provided on both the first plate 1 and the second plate 2. The rotating holes 45 are connected to the stop hole 44. The fixing component 4 also includes a pin 42. Four sets of stop blocks 43 are installed on both sides of the pin 42 along its diameter. The pin 42 is inserted into the insertion hole 41, and the stop block 43 enters the stop hole 44. When the stop block 43 is inserted into the rotating hole 45, the pin 42 rotates, and the stop block 43 enters the rotating hole 45 in the first plate 1 and the second plate 2 respectively and locks in place.

[0032] Working principle: Install the water storage pipe inside the water pipe 3, and pass both ends of the water pipe through the inlet 11 and the outlet 21 respectively. Then, align the first plate 1 and the second plate 2 together. Insert the pin 42 into the insertion hole 41 and push the pin 42 to move the stop block 43 in the stop block hole 44. When the stop block 43 is inserted into the rotating hole 45, rotate the pin 42, and the stop block 43 will enter the rotating hole 45 in the first plate 1 and the second plate 2 respectively and lock in place. The first plate 1 and the second plate 2 are then joined together. Position the second plate 2 facing indoors and connect the water pipe at the outlet 21 to the sprinkler head. When a fire breaks out indoors, water can be continuously supplied from the outdoor water inlet 11 to spray water into the room to extinguish the fire.

[0033] Example 2

[0034] refer to Figures 6 to 10 The fireproof door core panel that can be spliced ​​according to this embodiment preferably includes a first reinforcing plate 5 and a second reinforcing plate 6. The first reinforcing plate 5 and the second reinforcing plate 6 are spliced ​​onto the first plate 1 and the second plate 2 respectively by a reinforcing component 7 installed on the pin 42.

[0035] Preferably, the pin 42 is hollow inside, and the reinforcing component 7 includes a partition 71 installed in the middle of the pin 42. Press-and-telescopic components are respectively installed on both sides of the partition 71. The press-and-telescopic components have two states: retracted and extended. When in the extended state, the press-and-telescopic components are inserted into the first reinforcing plate 5 and / or the second reinforcing plate 6.

[0036] The press-and-retract assembly includes an elastic element 72 and a rotating block 73. The elastic element 72 is installed between the partition 71 and the rotating block 73, and the elastic element 72 is rotatably connected to the rotating block 73 through a plate fixedly installed on the elastic element 72. A set of inserts 74 are installed at both ends of the rotating block 73 along its diameter. A retaining ring 75 is fixedly installed on the inner wall of the end of the pin 42 away from the partition 71. The retaining ring 75 has an insertion port 76 and a locking position 78 at both ends of the two sets of diameters at the end facing the partition 71. The depth of the insertion port 76 is greater than that of the locking position 78. The inserts 74 intermittently engage with the insertion port 76 and the locking position 78. An insert rod 77 is inserted into the retaining ring 75. A locking block is provided at the end of the insert rod 77 near the partition 71, which engages with the insertion port 76. The locking block and the insert 74 are in intermittent contact.

[0037] Preferably, the lines connecting the two sets of sockets 76 and the two sets of locking positions 78 are perpendicular.

[0038] When in the extended state, the elastic element 72 returns to its original shape, the insert block 74 is inserted into the socket 76, and the insert rod 77 extends out of the first plate 1 / second plate 2 and is inserted into the reinforcing plate 1 / reinforcing plate 2; when in the retracted state, the elastic element 72 is compressed, and the insert block 74 is inserted into the locking position 78.

[0039] Working principle: Because water pipes 3 are installed inside the first board 1 and the second board 2, the boards become thinner at the corresponding locations. When better sound insulation and fireproofing are required, reinforcement board 5 and / or reinforcement board 6 can be spliced ​​together to achieve the desired effect. When splicing is required, press the insertion rod 77. The insertion rod 77 pushes the rotating block 73 to rotate, causing the insertion block 74 to disengage from the locking position 78 and insert into the insertion port 76 along the bottom edge of the retaining ring 75. The insertion block 74 pushes the insertion rod 77 to extend, and the insertion rod 77 is then inserted into reinforcement board 5 and / or reinforcement board 6 to complete the splicing.
