Embodiment 1

[0036] Such as Figure 1-3 As shown, a heavy-duty door includes a door leaf 1, and further includes an upper shaft and a floor spring 2. The ground shaft of the floor spring 2 is connected to the bottom of the door leaf 1, and the upper shaft includes a shaft 31 and a tapered roller bearing 32, The shaft 31 is rotatably connected to the tapered roller bearing 32, the lower end of the shaft 31 is connected to the frame on the top of the door leaf 1, the upper and lower ends of the shaft 31 are fixed by double nuts, and the double nut at the lower end is connected to the door leaf 1 to prevent the door leaf 1 from falling off. The tapered roller bearing 32 is arranged on a connecting piece for connecting to the door frame or beam 4. The sky shaft and the ground shaft are arranged coaxially, and the connecting piece includes The housing 5, the tapered roller bearing 32 is connected to the inside of the housing 5, the bottom of the housing 5 is provided with a through hole adapted ...

Embodiment 2

[0038] A method for installing a heavy door includes using a heavy door as in Example 1, such as Figure 4 , Its installation method includes the following steps:

[0039] Step 1. Pre-bury the floor spring 2;

[0040] Step 2: Connect the shaft 31 to the frame on the top of the door leaf 1;

[0041] Step 3: Connect the connecting piece to the door frame or beam 4;

[0042] Step 4: Connect the bottom of the door leaf 1 to the ground shaft of the floor spring 2;

[0043] Step 5: Connect the shaft 31 to the connecting piece, and then connect the tapered roller bearing 32.

[0044] The floor spring 2 is pre-embedded, the double nut is welded and connected to the inner side of the frame at the top of the door leaf 1, and then the shaft 31 is screwed into the double nut and tightened, and the shell 5 is welded to the The door frame or beam 4, and then lift the door leaf 1 so that the shaft of the floor spring 2 is inserted into the shaft hole under the door leaf 3, and then push the shaft 31 i...

Abstract

The invention discloses a heavy door and a mounting method. The stability of the heavy door in the using process can be improved; the heavy door can bear a larger load, has better stiffness, is more suitable for low-speed and heavy-load using scenes, is simple in structure, convenient to mount and convenient to open, and is suitable for frequent use; improvement on the safety coefficient of the heavy door is facilitated; a superhigh and superheavy door leaf is effectively prevented from sinking down, falling out and shifting, so that the service life of the door is prolonged; the post maintenance cost is effectively reduced, and the cost of an entrance door project is saved; the quality of the project is improved, and potential safety accidents are avoided; the heavy door can be conveniently and quickly mounted, and improvement on the construction safety is facilitated; alignment of an earth axis and a celestial axis is facilitated so as to control the verticality of the door leaf.

Description

Technical field [0001] The invention relates to the field of construction engineering construction, in particular to a heavy door and an installation method. Background technique [0002] In urban construction, in order to make the appearance of the building more beautiful, and at the same time convenient to enter and exit, and automatically close, some office buildings, hotels and other public buildings often use super-high and over-weight large entrance doors, which are often more than 3m high. With a weight of more than 200kg, stability problems are prone to occur during installation and use, which may bring potential safety hazards. [0003] In the prior art, a floor spring door is usually used to realize the bidirectional opening and automatic closing of the door through the cooperation of the sky shaft and the earth shaft. The sky shaft structure is mainly composed of a positioning piece and a positioning pin passing through. One end of the positioning pin is connected to the...
