[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1 , which is the first embodiment of the utility model, and provides a splicing mechanism, including a bearing assembly 100, including a first top arch 101 and a second top arch 102; and,

[0035] The locking assembly 200 includes a locking plate 201 disposed at one end of the second top arch 102 and a rotating shaft 201a disposed inside the locking plate 201; and,

[0036] The connecting assembly 400 includes a connecting column 401 disposed at one end of the first top arch 101; and

[0037] The reset assembly 300 includes a rotating rod 302 disposed inside the rotating shaft 201 a and a rotating plate 302 a disposed outside the rotating rod 302 .

[0038] The bearing assembly 100 further includes a corbel 103 disposed below the first top arch 101 and the second top arch 102 .

[0039] The locking assembly 200 further includes a through slot disposed inside the locking plate 201 , and a locking hook 202 is disposed on the outer side of the rotating shaft 201 a .

[0040] The connecting assembly 400 further includes connecting rods 401 a disposed on both sides of the connecting column 401 , and the connecting rods 401 a are adapted to the size of the through slot inside the locking plate 201 .

[0041] Usage process: When the arch needs to be quickly spliced, first align the first arch 101 with the second arch 102 and merge them together. When the first arch 101 and the second arch 102 are merged, the connecting rods 401a at both ends of the connecting column 401 will be embedded in the through grooves in the locking disk 201, and the locking hook 202 will be lifted up until it is behind the locking hook 202. At this time, the hook shape of the locking hook 202 is used to hook the connecting rod 401a to fix it, thereby realizing the rapid assembly of the arch, reducing the time consumed, and allowing the arch to protect the staff as soon as possible.

[0042] Example 2

[0043] Reference Figures 1 to 4 , which is the second embodiment of the utility model, is different from the previous embodiment in that it also includes: the reset assembly 300 also includes a turntable 303 arranged at one end of the rotating plate 302a, an axle is arranged inside the turntable 303, a ratchet 304 is arranged between the turntables 303, and a ratchet groove 301 is arranged inside the rotating shaft 201a.

[0044] An elastic member is provided inside the rotating rod 302, and the elastic member is a torsion spring. When the rotation of the rotating rod 302 is canceled, the torsion spring provided inside the rotating rod 302 drives the rotating rod 302 to reverse, so that the ratchet groove 301 and the ratchet pawl 304 cooperate, so that the rotating shaft 201a does not rotate. When the rotating rod 302 is reset, the handrail at the rear end of the rotating rod 302 is in a vertical state, thereby preventing falling rocks from hitting the handrail at the rear end of 302, causing the arch to not be released.

[0045] Usage process: When the arch needs to be disassembled, the rotating rod 302 is rotated to drive the rotating plate 302a to rotate, the rotating plate 302a drives the rotating disk 303 to rotate, and the rotating disk 303 drives the pawl 304 to rotate. The pawl 304 passes through the ratchet groove 301 set inside the rotating shaft 201a, thereby driving the rotating shaft 201a to rotate through the pawl 304, and then the locking hook 202 is driven to tilt upward through the rotating shaft 201a, thereby completing the unlocking of the arch.

[0046] Example 3

[0047] Reference Figures 1 to 4 , which is the third embodiment of the utility model, further provides an underground factory building arch, including a combination assembly 500, including a support rod 503 arranged inside the first arch 101 and the second arch 102.

[0048] The combined component 500 also includes a construction base 501 arranged inside the first top arch 101 and the second top arch 102, a sprayed mix layer 502 is provided on one side of the construction base 501, a steel lining unit 504 is provided on one side of the sprayed mix layer 502, anchor cables 505 are provided above the first top arch 101 and the second top arch 102, and anchor rods 506 are provided above the first top arch 101 and the second top arch 102. When the conventional anchor cables 505 are tensioned, the force at the anchor pier is concentrated, which is easy to cause damage or destruction to the rock mass at that location, thereby affecting the stability of the overall surrounding rock. The steel lining unit 504 can be jointly stressed with the anchor pier to evenly distribute the force during tensioning to the entire steel lining unit 504, thereby ensuring the stability and safety of the surrounding rock.

[0049] The material of the construction base layer 501 is cement concrete, and the material of the sprayed mixed layer 502 is dry sprayed concrete.

[0050] Usage process: firstly, blast excavate the pilot hole in the factory building arch, clean up the loose floating stones on the face and then spray concrete for 5 cm to seal it, backfill the over-excavated part with sprayed concrete, make the surface of the sprayed concrete bucket smooth, construct the system anchor 506, and drill the holes for anchor cable 505 simultaneously, use the support rod 503 to push the prefabricated steel tile to the arch surface, install the anchor cable 505 and tension it, the steel pad of anchor cable 505 should be slightly larger than the anchor cable hole, and finally, install the first arch 101 and the second arch 102 on both sides of the arch layer through the construction process of the pilot hole in the arch, and place the outer sides of the steel tiles on both sides on the reserved rock sill of the factory building corbel, so that the steel arch frame linear support and the steel lining unit can seal and support the entire face, with a larger force area and great guarantee for the construction safety of the working face.
