Description

Technical Field

[0001] This invention belongs to the field of office building construction, and specifically relates to a method for attaching a tripod to a construction elevator on the first floor of an office building. Background Technology

[0002] Construction elevators consist of several parts, including the car, drive mechanism, standard section, wall attachment, chassis, railing, and electrical system. They are commonly used construction machinery for carrying people and goods.

[0003] Currently, many public buildings, such as office buildings, have relatively high first-floor heights. With the improvement of building safety construction standards, the distance between the construction elevator and the wall is required to be ≤9m. However, the first-floor height of office buildings is currently around 11m. Therefore, for buildings such as office buildings with extremely high first-floor heights, it is difficult to attach the construction elevator to the wall, and the construction elevator poses a safety hazard. Summary of the Invention

[0004] This invention provides a method for attaching a construction elevator to a tripod on the first floor of an office building, which solves the technical problem of difficulty in attaching the construction elevator to the wall and the potential safety hazards of the construction elevator in buildings such as office buildings with extremely high first-floor heights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A construction elevator is attached to a tripod on the first floor of an office building, comprising embedded parts, columns, diagonal bracing columns, and beams. The elevator foundation is located on the outside of the building wall, and a standard elevator section is set on the elevator foundation. Several wall-mounted rods attached to the building wall are installed on the standard elevator section in the height direction. The building wall and the elevator foundation are located on the basement roof slab. Plain soil backfill is provided on one side of the elevator foundation, and a retaining wall is set around the plain soil backfill. Concrete is poured on the top of the plain soil backfill. The embedded parts include several front embedded parts and rear embedded parts set in the concrete. The line connecting the front embedded parts is parallel to the standard elevator section, and the line connecting the rear embedded parts is parallel to the standard elevator section and located on the side of the front embedded parts away from the standard elevator section. The top of the front embedded parts is fixed. The building has a column with a square steel welded to its top. The square steel runs the entire length of the column and is parallel to the standard elevator section. A diagonal brace is fixed to the top of the rear embedded part. The top of the diagonal brace is welded to the square steel. A horizontal beam parallel to the standard elevator section is welded to the top of the square steel. The outer edge of the building wall is the structural edge line. The backfill soil extends beyond the structural edge line. The side of the horizontal beam closest to the standard elevator section is flush with the structural edge line. The wall-mounted rod is connected to the horizontal beam. The front and rear embedded parts have the same structure. The front embedded part includes an embedded plate and legs. The top of the embedded plate is flush with the top of the concrete. Four legs are set in a rectangular arrangement. Each leg includes a leg welded to the embedded plate and a right-angle bend at the bottom of the leg. A grid of steel bars is laid in the concrete. The center point of the four legs is vertically aligned with one of the intersections of the steel bars.

[0006] Preferably, an angle steel plate is welded onto the crossbeam, with one side of the angle steel plate welded to the crossbeam and the opening of the angle steel plate facing downwards. Two connecting plates perpendicular to the angle steel are welded onto the angle steel plate, and a butt plate located between the two connecting plates is provided on the wall-mounted rod. The connecting plates and the butt plate are connected by pins.

[0007] Preferably, the upright column is welded to the front embedded part, and the diagonal brace column is welded to the rear embedded part.

[0008] Preferably, the upright column is detachably connected to the front embedded part, and the diagonal brace column is detachably connected to the rear embedded part.

[0009] Preferably, the columns, diagonal braces, and crossbeams are all I-beams.

[0010] Preferably, the angle between the diagonal bracing column and the horizontal plane is 40-60°.

[0011] Preferably, the spacing between the columns is 2250mm.

[0012] A construction method for attaching a tripod to a construction elevator on the ground floor of an office building includes the following steps:

[0013] Step 1: Backfill the bottom of the building with plain soil, and fix the perimeter of the backfill with retaining walls.

[0014] Step 2: Lay steel bars on top of the plain soil and arrange the front and rear embedded parts, and erect the formwork;

[0015] Step 3: Pour concrete on top of the plain soil;

[0016] Step 4: Fix the column to the front embedded part, fix the square steel to the column, and fix the diagonal bracing column between the square steel and the rear embedded part;

[0017] Step 5: Weld a crossbeam to the top of the square steel, weld an angle steel plate onto the crossbeam, and weld a connecting plate onto the angle steel plate;

[0018] Step 6: Connect the wall-mounted rods and connecting plates installed on the standard elevator section using pins to complete the wall attachment.

[0019] The beneficial effects of this invention are as follows: The invention rationally arranges the construction site, arranges backfill with plain soil and raises the height of retaining walls, then pours concrete on the backfill, and places embedded parts on the concrete. A wall-mounted triangular frame is set up through the embedded parts to stabilize the structure. The wall-mounted rods of the elevator standard section can be connected to the wall-mounted triangular frame, thus ensuring that the spacing between the wall-mounted rods does not exceed 9m, meeting construction safety requirements. Furthermore, the combination of plain soil backfill and concrete results in a short construction period and low construction cost, representing significant progress. Moreover, the plain soil backfill extends beyond the structural edge line, and the outer edge of the crossbeam is flush with the structural edge line, thus achieving correspondence with the wall-mounted positions on other floors. Therefore, the wall-mounted rods of the elevator standard section do not need to be fabricated separately; all wall-mounted rods can be of the same standard. This invention has an ingenious structure and reasonable design, and has excellent prospects for widespread application.

[0030] Combination Figures 1-7 A construction elevator is attached to a tripod on the first floor of an office building, including embedded parts 1, columns 2, diagonal bracing columns 3, and beams 4. An elevator foundation 5 is located on the outer side of the building wall. An elevator standard section 6 is installed on the elevator foundation 5. Several wall-mounted rods 7 are installed on the elevator standard section 6 in the height direction, attached to the building wall. The building wall and elevator foundation 5 are located on the basement roof slab 8. Plain soil backfill 9 is provided on one side of the elevator foundation 5, and a retaining wall 10 is provided around the plain soil backfill 9. Concrete 11 is poured on the top of the plain soil backfill 9. The embedded parts 1 include several front embedded parts 12 and rear embedded parts 13 installed on the concrete 11. The line connecting the front embedded parts 12 is parallel to the elevator standard section 6, and the line connecting the rear embedded parts 13 is parallel to the elevator standard section 6 and located on the side of the front embedded parts 12 away from the elevator standard section 6. A column 2 is fixed to the top of the front embedded part 12, and a square steel 14 is welded to the top of the column 2. Steel 14 is set along its entire length and is parallel to the standard elevator section 6. The top of the rear embedded part 13 is fixed with a diagonal brace 3. The top of the diagonal brace 3 is welded to the square steel 14. The top of the square steel 14 is welded with a crossbeam 4 parallel to the standard elevator section 6. The outer side of the building wall is the structural edge line 15. The plain soil backfill 9 extends out of the structural edge line 15. The side of the crossbeam 4 closest to the standard elevator section 6 is flush with the structural edge line 15. The wall-mounted rod 7 is connected to the crossbeam 4. The front embedded part 12 and the rear embedded part 13 have the same structure. The front embedded part 12 includes an embedded plate 16 and a support leg 17. The top of the embedded plate 16 is flush with the top of the concrete 11. The support leg 17 is set in four rectangular positions. The support leg 17 includes a support leg 18 welded to the embedded plate 16 and a right-angle bend 19 at the bottom of the support leg 18. A grid of steel bars 20 is laid in the concrete 11. The center point of the four support legs 17 is vertically aligned with one of the intersections of the steel bars 20.

[0031] This invention rationally arranges the construction site, deploying plain soil backfill 9 and retaining walls 10 to increase the height, then pouring concrete 11 on the plain soil backfill 9, and placing embedded parts 1 on the concrete 11. A wall-mounted triangular frame is set up through the embedded parts 1 to stabilize the structure. The wall-mounted rods 7 of the elevator standard section 6 can be connected to the wall-mounted triangular frame, ensuring that the spacing between the wall-mounted rods 7 does not exceed 9m, meeting construction safety requirements. Furthermore, the combination of plain soil backfill 9 and concrete 11 results in a short construction period and low construction cost, representing significant progress. The plain soil backfill 9 extends beyond the structural edge line 15, and the outer edge of the crossbeam 4 is flush with the structural edge line 15, thus achieving correspondence with the wall-mounted positions on other floors. This eliminates the need for additional fabrication of the wall-mounted rods 7 of the elevator standard section 6; all wall-mounted rods 7 can be of the same standard. The well-matched positions of the embedded parts 1 and the reinforcing bars 20 ensure the stability of the embedded parts 1. This invention has an ingenious structure and reasonable design, with excellent prospects for widespread application.

[0032] Angle steel plate 21 is welded onto the crossbeam 4. One side of the angle steel plate 21 is welded onto the crossbeam 4. The opening of the angle steel plate 21 faces downward. Two connecting plates 22 perpendicular to the angle steel are welded onto the angle steel plate 21. A butt plate located between the two connecting plates 22 is provided on the wall-mounted rod 7. The connecting plate 22 and the butt plate are connected by pins, so that the wall-mounted rod 7 can be easily connected to the attached tripod.

[0033] The column 2 can be welded to the front embedded part 12 or detachably connected to the front embedded part 12. The detachable connection method is common knowledge and will not be elaborated here. The diagonal brace column 3 can be welded to the rear embedded part 13 or detachably connected to the rear embedded part 13.

[0034] Column 2, diagonal bracing column 3, and beam 4 are all made of I-beams, which are readily available and have high structural strength. The angle between diagonal bracing column 3 and the horizontal plane is 40-60°, resulting in high overall structural strength. The spacing between columns 2 is 2250mm, ensuring high overall structural strength.

[0035] A construction method for attaching a tripod to a construction elevator on the ground floor of an office building includes the following steps:

[0036] Step 1: Backfill the bottom of the building with plain soil, and fix the perimeter of the backfill with retaining walls 10.

[0037] Step 2: Lay 20 steel bars on the top of the plain soil and arrange the front embedded parts 12 and the rear embedded parts 13, and set up the formwork;

[0038] Step 3: Pour concrete 11 on top of the plain soil;

[0039] Step 4: Fix column 2 on the front embedded part 12, fix square steel 14 on column 2, and fix diagonal bracing column 3 between square steel 14 and rear embedded part 13.

[0040] Step 5: Weld a crossbeam 4 to the top of the square steel 14, weld an angle steel plate 21 to the crossbeam 4, and weld a connecting plate 22 to the angle steel plate 21.
