[0028] Please see attached Figure 1 To Attachment Figure 3 A temporary overhead passage structure comprises a passage main beam 1, a protective enclosure component 2 and a passage unit plate 4; the two ends of the passage main beam 1 are respectively erected on the floor slabs 3 on both sides, so that a pair of passage main beams 1 are arranged in parallel and straddle the cantilever gap 301 between the floor slabs 3 on both sides; a plurality of passage unit plates 4 are spliced ​​end to end in sequence to form a passage plate, and the passage plate is laid on a pair of passage main beams 1 to form a passage between the floor slabs 3 on both sides; a pair of protective enclosure components 2 are respectively vertically arranged on a pair of passage main beams 1, and the two ends of each group of protective enclosure components 2 extend to the floor slabs 3 on both sides.

[0029] A pair of channel main beams 1 are overlapped between two floor slabs 3 to support the channel plate formed by splicing a number of channel unit plates 4, so that the channel plate across the cantilever gap 301 provides an overhead passage platform for the cantilever gap 301 between the two side floor slabs 3, and transfers the load during passage to the two side floor slabs 3 to ensure the safe passage of construction personnel and organizations. At the same time, the enclosure components 2 on the pair of channel main beams 1 provide lateral protection, and the enclosure components 2 extend to the two side floor slabs 3 to ensure the effectiveness of protection and prevent personnel or equipment on the channel plate from falling.

[0030] Please see attached Figure 8 and attached Fig. 9 Each of the channel main beams 1 includes a main beam 101 and a load-bearing beam 102; the two ends of the main beam 101 are respectively overlapped on the floor slabs 3 on both sides, and the main beam 101 spans the cantilever gap 301; a pair of channel main beams 1 are respectively provided with load-bearing beams 102 on the opposite sides of the main beams 101, and the channel unit plates 4 are laid on the pair of load-bearing beams 102.

[0031] Preferably, the main beam 101 can be made of square steel ("U" shaped cross section), and the specifications and length of the square steel can be adaptively adjusted according to actual use requirements to ensure the bearing capacity of the channel. The load-bearing beam 102 can be welded to the main beam 101 using steel plates or angle steels ("L" shaped cross section or "I" shaped cross section), and the bottom surface of the load-bearing beam 102 is flush with the bottom surface of the main beam 101, and is used to bear the channel unit plate 4.

[0032] Please see attached Figure 4 To Attachment Figure 7 The channel unit plate 4 is provided with downwardly bent portions 401 at both side edges, and the outer walls of the downwardly bent portions 401 on both sides are respectively attached to one side of a pair of main beams 101 that are oppositely arranged, and the bottom of the downwardly bent portions 401 is abutted against the load-bearing beam 102, so that the top surface of the channel unit plate 4 is flush with the top surface of the main beam 101.

[0033] Preferably, the channel unit plate 4 can be made of patterned steel plate, and the edges on both sides are bent downward by 90° to form a lower bend 401, and the height of the lower bend 401 is equal to the thickness of the main beam 101 minus the thickness of the load-bearing beam 102, so as to ensure that when the lower bend 401 is overlapped on the load-bearing beam 102, the top surface of the channel unit plate 4 is flush with the top surface of the main beam 101.

[0034] The outer wall spacing of the lower bent parts 401 on both sides of the channel unit plate 4 is basically consistent with the spacing of the opposite sides of a pair of main beams 101, so that when the channel unit plate 4 is laid on a pair of bearing beams 102, there will be no large gap between it and the channel main beam 1, thereby ensuring the safety of the channel unit plate 4.

[0035] Please see attached Figure 4 To Attachment Figure 7 A unit plate beam 5 is provided between the bottom surface of the channel unit plate 4 and the inner wall of the lower bent portion 401 on both sides thereof. The unit plate beam 5 is arranged perpendicular to a pair of main beams 101 , and both ends of the unit plate beam 5 are placed on the load-bearing beams 102 of the pair of main beams 101 .

According to the size of the channel unit plate 4, three unit plate beams 5 can be arranged at equal intervals.

[0037] Please see attached Figure 4 To Attachment Figure 7 A hanging plate 7 is formed at one end of the channel unit plate 4, and a hanging groove 8 is formed at the other end of the channel unit plate 4. The hanging plate 7 can be matched and inserted into the hanging groove 8, so that two adjacent channel unit plates 4 are spliced ​​into a flat plate structure.

[0038] Preferably, the hanging plate 7 is in an inverted L-shaped structure, and the hanging groove 8 is in a U-shaped structure. By matching and plugging the hanging plate 7 and the hanging groove 8, the splicing convenience and efficiency of the two adjacent channel unit plates 4 can be improved, and the splicing position connection is reliable, ensuring the integrity and bearing capacity of the channel plate.

[0039] Please see attached Figure 4 To Attachment Figure 7 The two ends of the hanging plate 7 are respectively formed with rope holes 9, and the pulling rope is passed through the rope holes 9.

[0040] Preferably, the length of the hook of the hanging plate 7 is consistent with the length of the hanging groove 8, and is slightly smaller than the length of the hanging plate 7, so that a certain space is reserved at both ends of the hanging plate 7 to set the rope threading hole 9. The steel wire rope is threaded in the rope threading hole 9, and the threading of the steel wire rope will not interfere with the plugging of the hanging plate 7 and the hanging groove 8. After the steel wire rope is threaded, it is convenient for construction workers to pull the channel unit plate 4 and lay the channel unit plate 4 on a pair of channel main beams 1, which is convenient for disassembly and assembly and has high safety.

[0041] The channel unit plate 4, the lower bent portion 401, the hanging plate 7 and the hanging groove 8 can be integrally formed by a mold, and are easy to be standardized and mass-produced.

[0042] Please see attached Figure 8 A plurality of main beam mounting holes 6 are provided at intervals on the main beam 101 , and the enclosure assembly 2 is fixedly mounted on the main beam 101 through the main beam mounting holes 6 by means of mounting parts.

[0043] Preferably, the main beam mounting holes 6 can be threaded holes, and the mounting members can be bolts, which facilitates the convenient disassembly and assembly of the enclosure assembly 2 and the main beam 101, and has high connection reliability. The number and arrangement spacing of the main beam mounting holes 6 can be adaptively adjusted according to actual installation requirements.

[0044] Please see attached Figure 2 and attached Figure 3The enclosure assembly 2 includes columns 201 and fences 202 . The columns 201 are vertically mounted on the main beam 101 through the mounting pieces via the main beam mounting holes 6 , and the fences 202 are installed between every two adjacent columns 201 .

[0045] Preferably, the fence 202 can be made of a wire mesh fence with good protective effect, and the column 201 can be made of square steel. The bottom is vertically installed on the main beam 101 through the ear plate, the mounting part and the main beam mounting hole 6. The specifications of the column 201 and the fence 202 can be adaptively adjusted according to actual usage requirements.

[0046] Please see attached Figure 1 To Attachment Fig. 9 , the installation method of the utility model is:

[0047] The construction workers stand on the floor slabs 3 on both sides and transfer the channel main beam 1 from one side of the floor slab 3 to the other side, so that the channel main beam 1 is set across the cantilever gap 301. The setting spacing of a pair of channel main beams 1 is determined according to the width of the channel unit plate 4, and the two ends of the pair of channel main beams 1 are overlapped and fixed on the floor slabs 3 on both sides by chemical expansion bolts.

[0048] A shorter channel main beam 1 can be directly transferred manually, and a longer or heavier channel main beam 1 can be transferred with the assistance of equipment such as a hand winch to ensure construction safety.

[0049] On the floor 3 on one side, steel wire ropes are passed through the rope holes 9 at both ends of the hanging plate 7 of the first channel unit plate 4, and the construction workers on the floor 3 on the other side move the first channel unit plate 4 from the floor 3 on one side to the floor 3 on the other side by pulling the steel wire ropes.

[0050] During the movement of the first channel unit panel 4, the construction workers on the floor slab 3 on one side splice the second channel unit panel 4 to the first channel unit panel 4 through the hanging plate 7 and the hanging groove 8, and the construction workers on the floor slab 3 on the other side continue to pull the wire rope to make the first and second channel unit panels 4 move synchronously toward the floor slab 3 on the other side.

[0051] During the movement of the first and second channel unit panels 4, the third channel unit panel 4 is spliced ​​on the second channel unit panel 4 through the hanging panel 7 and the hanging groove 8, and so on, until the first channel unit panel 4 moves to the floor slab 3 on the other side, and the last channel unit panel 4 is located on the floor slab 3 on one side, forming a channel panel spanning the cantilever gap 301.

[0052] The bottom of the channel plate is placed on a pair of bearing beams 102 through the lower bend 401 and the unit plate beam 5, and there is no large gap between the two sides of the channel plate and the main beam 101, and the top surface of the channel plate is flush with the top surface of the main beam 101. The channel unit plate 4 and the channel main beam 1 can be fixed by spot welding and clamping to prevent the channel unit plate 4 from slipping.

[0053] After the construction workers wear the safety rope, they fix the columns 201 on the main beam 101 through the mounting pieces on the channel board through the main beam mounting holes 6, and install fences 202 between adjacent columns 201. During the construction process, the channel board can provide a safe passage at the cantilever gap 301 for construction workers and organizations.

[0054] When the passage is no longer needed, the construction workers tie a safety rope, remove the columns 201 and fences 202 on the passage board, connect the steel wire ropes through the rope holes 9 at both ends of the hanging plate 7 of the first passage unit plate 4, and cut off the welding points between the passage unit plate 4 and the passage main beam 1. The construction workers on one side of the floor slab 3 pull the steel wire ropes to pull all the passage unit plates 4 onto the floor slab 3, and lift the passage unit plate 4 to separate it from the adjacent passage unit plates 4. Then remove the expansion bolts used to fix a pair of passage main beams 1 on the floor slabs 3 on both sides, and remove the passage main beam 1.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
