Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction method for a composite steel ultra-long triangular external protective frame for high-rise prefabricated buildings. Background Technology

[0002] In the construction of multi-story or high-rise frame buildings, the limitations of the external environment often result in the lack of support points for cantilever floor slabs, making construction difficult. Traditionally, the construction of external protective frames using combined steel triangular frames typically employs a combination of 1500-type combined steel triangular frames and ground-mounted scaffolding. However, on prefabricated components with balcony cladding, traditional combined steel triangular frames are insufficient in size to meet the requirements for erecting external protective frames. To better address the foundation construction of external protective frames in special locations, the integration of different construction techniques, further reduce construction difficulty, and accelerate construction progress, we offer a construction method for ultra-long combined steel triangular external protective frames in high-rise prefabricated buildings to solve these problems.

[0043] Preferably, the extra-long combined steel triangular frame 4 is welded from L90*8, L80*5, and L40*4 angle steel;

[0044] The working principle and beneficial effects of the above technical solution are as follows: Double I-beam steel columns 3 are installed at the indoor balcony location. The base of the double I-beam steel columns 3 is welded to the fixing frame 6. The fixing frame 6 is fixed to the concrete structure layer of the floor using expansion bolts 1. The top of the double I-beam steel columns 3 is fixed to the top reinforced concrete structural beam on the indoor side using a support frame 2 and expansion bolts 1. After the double I-beam steel columns 3 are installed, the extra-long combined steel triangular frame 4 is fixed to the double I-beam steel columns 3 using high-strength bolts 12. After the extra-long combined steel triangular frame 4 is installed, the outer protective frame 7 is erected along the floor height, and wall ties are installed in each balcony.

[0049] This invention features a simple process and convenient construction, solving the problem of the foundation of the combined steel ultra-long triangular external protective frame at the location of the balcony external hanging plate in high-rise prefabricated buildings.

[0050] Example 2

[0051] Based on Example 1, please refer to Figure 2-8 The connecting device 5 includes: a positioning ring 13, which is fixedly connected to the outer protective frame 7; a bidirectional hydraulic cylinder 14, which is fixedly connected to the inner wall of the right side of the positioning ring 13; two sets of arc-shaped connecting rods 15 are symmetrically fixedly connected to the two output ends of the bidirectional hydraulic cylinder 14, and a rubber brake ring 16 is sleeved on each set of arc-shaped connecting rods 15; two ends of a connecting spring 17 are fixedly connected to the two sets of rubber brake rings 16 respectively; two ends of a connecting spring 18 are fixedly connected to the two sets of arc-shaped connecting rods 15 respectively; a locking unit 19 is located between the two sets of rubber brake rings 16 and close to the bidirectional hydraulic cylinder 14; and an auxiliary unit 20 is located at the bottom center of the inner wall of the positioning ring 13 and connected to the rubber brake rings 16.

[0052] Preferably, the locking unit 19 includes: a positioning plate 21, which is fixedly connected to the inner wall of the right side of the positioning ring 13; a sliding groove 37 is provided on the positioning plate 21, and a plurality of spherical grooves 38 are provided on the inner wall of the sliding groove 37; a limiting member 22 is fixedly connected to the positioning plate 21; two sets of ring sleeves 25 are symmetrically provided at both ends of the limiting member 22, and two sets of locking rods 26 are symmetrically and movably arranged in the two sets of ring sleeves 25; a bidirectional hydraulic cylinder 39 is fixedly connected to the middle of the limiting member 22, and the two output ends of the bidirectional hydraulic cylinder 39 are fixedly connected to the two sets of locking rods 26 respectively.

[0053] Preferably, the connecting post 23 is movably disposed within the slide groove 37, and one end of the first connecting rod 24 is rotatably connected to the locking rod 26, and the other end of the first connecting rod 24 is rotatably connected to the connecting post 23. One end of the connecting post 23 disposed within the slide groove 37 is provided with a through groove 27, and two sets of second connecting rods 28 are movably disposed within the through groove 27. Both ends of the bidirectional hydraulic cylinder 30 are respectively fixedly connected to the two sets of second connecting rods 28, and the ends of the two sets of second connecting rods 28 that are far apart from each other are fixedly connected with spherical locking heads 29.

[0054] Preferably, the auxiliary unit 20 includes: an anti-detachment fixing block 36 fixedly sleeved on the annular electromagnetic coil 31, the anti-detachment fixing block 36 being fixedly connected to the inner wall of the right side of the positioning ring 13; a rotating arm 32 disposed inside the annular electromagnetic coil 31, and the rotating arm 32 being rotatably connected to the inner right side of the positioning ring 13; arc-shaped magnetic suction pieces 35 being fixedly connected to both ends of the rotating arm 32 near the inner wall of the annular electromagnetic coil 31, and the arc-shaped magnetic suction pieces 35 being movably connected to the inner wall of the annular electromagnetic coil 31; one end of the third connecting rod 33 being rotatably connected to the rotating arm 32; the other end of the third connecting rod 33 being rotatably connected to the rubber brake ring 16; and a magnetic piece 34 being fixedly connected to the rubber brake ring 16.

[0055] Preferably, the positioning ring 13 is a cylinder with a one-way opening.

[0056] The working principle and beneficial effects of the above technical solution are as follows: When in use, first fix the positioning ring 13 on the outer protective frame 7, then insert the double-layer wall connecting horizontal bar 9 into the positioning ring 13, and then drive the two sets of arc-shaped connecting rods 15 to move away from each other by starting the bidirectional hydraulic cylinder 14, so that the two sets of rubber brake rings 16 abut against the inner wall of the double-layer wall connecting horizontal bar 9 to prevent it from loosening.

[0057] At the same time, the bidirectional hydraulic cylinder 39 starts, driving the two sets of locking rods 26 to slide along the ring 25, so that the two sets of locking rods 26 are respectively inserted into the slots 40 opened in the rubber brake ring 16. When the two sets of locking rods 26 move in a direction away from each other, they will drive the connecting column 23 to slide in the sliding groove 37 of the positioning plate 21 through the first connecting rod 24. After stopping, the bidirectional hydraulic cylinder 30 starts, driving the spherical locking head 29 into the spherical groove 38 through the two sets of second connecting rods 28. Due to the different wall thicknesses of the horizontal rods 9 of the double-layer wall tie, Therefore, the movement distance of the rubber brake ring 16 when it comes into contact with the horizontal bar 9 of the double-layer wall tie is also different. In addition, a small displacement increment will be generated between the rubber brake ring 16 and the horizontal bar 9 of the double-layer wall tie each time it is used. Therefore, by setting several spherical grooves 38, the spherical locking head 29 can be inserted at any position, so that the positioning ring 13 can withstand greater pressure and ensure that the rubber brake ring 16 and the horizontal bar 9 of the double-layer wall tie are tightly fitted, so as to avoid affecting the load-bearing capacity, stability and use requirements of the structure due to excessive displacement.

[0058] Meanwhile, the rubber brake ring 16 pulls the rotating arm 32 to rotate via two sets of third connecting rods 33. After the bidirectional hydraulic cylinder 14 is closed, the annular electromagnetic ring 31 is energized to generate magnetic force. Since the arc-shaped magnetic absorbing piece 35 and the annular electromagnetic ring 31 have opposite magnetic forces, the arc-shaped magnetic absorbing piece 35 is firmly attracted to the inner wall of the annular electromagnetic ring 31, preventing the rotating arm 32 from rotating. The magnetic piece 34 and the annular electromagnetic ring 31 have the same magnetic force, so when the annular electromagnetic ring 31 is energized, it will give the magnetic piece 34 a repulsive force. This repulsive force will be applied to the double-layer wall-connecting horizontal bar 9 through the rubber brake ring 16, thereby ensuring the tightness of the connection between the double-layer wall-connecting horizontal bar 9 and the outer protective frame 7. Due to the repulsive force, the rubber brake ring 16 also has a certain displacement gap. When the outer protective frame 7 is affected by weather factors such as strong winds and shakes, it can make the double-layer wall-connecting horizontal bar 9 and the outer protective frame 7 have a certain flexibility, thereby enabling the entire protective frame 7 to maintain its original balance and improving the stability of the protective frame. Reality

[0059] Example 3

[0060] Based on any one of Examples 1-2, please refer to Figure 9-10 The locking device 11 includes: a connecting block 41 and a U-shaped frame 42. The protective frame 7 is fixedly connected to the connecting block 41 at one end near the extra-long combined steel triangular frame 4. The U-shaped frame 42 is fixedly connected to the connecting block 41 at one end near the connecting block 41. The drive motor 44 is fixedly connected to the U-shaped inner wall of the U-shaped frame 42, and a drive gear 43 is fixedly sleeved on the output shaft of the drive motor 44. The limiting block 46 is fixedly connected to the U-shaped inner wall of the U-shaped frame 42, and a rack 45 moves through the limiting block 46. The rack 45 meshes with the drive gear 43. A guide groove 47 is provided on the U-shaped inner wall of the U-shaped frame 42. A guide block 48 is movably disposed in the guide groove 47. The rack 45 is fixedly connected to the guide block 48 at one end near the guide block 48.

[0061] Preferably, one end of the first fixing plate 49 is fixedly connected to the guide block 48, and the other end of the first fixing plate 49 is fixedly connected to the second connecting block 51. The mounting sleeve 52 is fixedly connected to the second connecting block 51. A buffer spring 50 is provided between the mounting sleeve 52 and the U-shaped frame 42, and both ends of the buffer spring 50 are fixedly connected to the mounting sleeve 52 and the U-shaped frame 42 respectively. A hydraulic cylinder 53 is fixedly provided inside the mounting sleeve 52, and a pressure plate 54 is fixedly connected to the output end of the hydraulic cylinder 53.

[0062] The working principle and beneficial effects of the above technical solution are as follows: When in use, if the extra-long combined steel triangular frame 4 is welded with a profile with a larger width, after the U-shaped frame 42 installed on the protective frame 7 is fastened to the extra-long combined steel triangular frame 4, the hydraulic cylinder 53 is directly started to drive the pressure plate 54 to abut against the extra-long combined steel triangular frame 4, so that the pressure plate 54 tightly abuts the extra-long combined steel triangular frame 4 against the U-shaped frame 42, thereby connecting the extra-long combined steel triangular frame 4 and the protective frame 7 together.

[0063] If the extra-long combined steel triangular frame 4 is welded using a profile with a smaller width, the stroke of the hydraulic cylinder 53 is shorter. Therefore, after the U-shaped frame 42 installed on the protective frame 7 is fastened to the extra-long combined steel triangular frame 4, the drive motor 44 is started to drive the drive gear 43 to rotate. At this time, the rack 45 drives the guide block 48 to move in the guide groove 47 under the action of the drive gear 43. Under the action of the first fixed plate 49 and the second connecting block 51, the mounting sleeve 52 drives the hydraulic cylinder 53 to move towards the extra-long combined steel triangular frame 4, thereby shortening the distance between the hydraulic cylinder 53 and the extra-long combined steel triangular frame 4, making it easier for the hydraulic cylinder 53 to drive the pressure plate 54 to abut against the extra-long combined steel triangular frame 4.

[0064] The locking device 11 makes it very convenient to assemble the extra-long combined steel triangular frame 4 and the protective frame 7 together, which is easy to construct and has strong stability.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
