Description

Technical Field

[0001] This utility model relates to the field of engineering construction, and in particular to an unconventional installation device for an external wall suspended platform. Background Technology

[0002] Suspended platforms for high-altitude operations are suitable for exterior wall construction and decoration projects of high-rise and multi-story buildings. They can replace traditional scaffolding and lifting frames for exterior wall construction and are a highly efficient and multifunctional platform for high-altitude operations. Their main features are as follows:

[0003] (1) The suspended platform is easy and quick to set up. The suspension mechanism adopts counterweight balance and does not require pre-embedded parts, which does not affect the roof waterproofing and construction.

[0004] (2) The electric suspended platform is electrically driven, with a lifting speed of 9-11 m / min, which is highly efficient and flexible.

[0005] (3) The safety of the suspended platform construction is fully guaranteed. The ZLP high-altitude electric suspended platform is a standardized product manufactured in accordance with the national standard GB19155-2017. It has safety devices such as rope breakage anti-tilt safety lock, emergency stop device, speed limit protection, upper limit protection, and manual slow descent. Each suspended platform is also independently equipped with a safety life rope.

[0006] The suspended platform for high-altitude operations consists of a suspension mechanism, a working platform, a hoist, a safety lock, working wire ropes, safety wire ropes, a counterweight, travel limit switches, and an electrical control system. The suspension mechanism is erected above the building and suspends the working platform via wire ropes. The suspension mechanism is assembled from square steel pipes or channel steel. A counterweight is placed on the tail support of the suspension mechanism to balance the suspended platform system. No pre-embedded or other measures are required on the roof. The entire suspension mechanism can be adjusted horizontally and vertically according to the requirements of different roof structures.

[0007] However, in some unconventional buildings, such as the Chengdu Wanxing Environmental Protection Power Plant project, the main building roof has a double-row round steel beam structure. When constructing the exterior curtain wall decoration, the standard brackets of the hanging basket suspension mechanism cannot be installed, so the hanging basket cannot be used for the exterior curtain wall hoisting, which brings great trouble to the on-site construction. Therefore, it is urgent to design a new construction design scheme. Utility Model Content

[0008] The purpose of this utility model is to provide an unconventional installation device for an external wall suspended platform to solve the problem that a suspended platform suspension mechanism cannot be installed on a double-row round steel beam structure of a roof for curtain wall decoration construction.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: an unconventional installation device for an external wall suspended platform, comprising a suspension mechanism and a suspended platform. The suspension mechanism consists of a crossbeam, an upper column, and front and rear supports. The front and rear supports consist of a movable adjusting rod, a special-shaped support, and U-shaped clamp bolts. The upper end of the special-shaped support is fitted onto the lower end of the movable adjusting rod. The special-shaped support and the movable adjusting rod are fixedly connected by a positioning pin. The upper end of the movable adjusting rod is fixedly connected to the crossbeam. A base plate is welded to the bottom surface of the special-shaped support. A triangular reinforcing plate is welded between the special-shaped support and the base plate. The base plate has mounting holes for installing U-shaped clamp bolts. The base plates of the front and rear supports are respectively fixed to a double row of round steel beams at the construction site by U-shaped clamp bolts.

[0010] Preferably, the irregular support and the movable adjusting rod are provided with pin holes that match the positioning pins. There are multiple pin holes on the irregular support, and the multiple pin holes are evenly distributed along the length direction of the irregular support, with the interval between the pin holes being not less than 200 mm.

[0011] Preferably, the U-shaped clamp bolt is an M18 U-type bolt, the inner diameter of which matches the diameter of the double-row round steel beam.

[0012] Preferably, the two ends of the U-shaped clamp bolt are provided with locking nuts and washers, and the two ends of the U-shaped clamp bolt are fixed to the base plate of the irregular support by locking nuts.

[0013] Preferably, the base plate of the irregular support is provided with two sets of U-shaped clamp bolts, which are located on the left and right sides of the irregular support, respectively.

[0014] Preferably, the mounting hole is an elongated hole, the length of which is consistent with the length direction of the circular steel beam.

[0015] Preferably, the irregular support is an 80*80*3.75mm square tube column, and the base plate is a 250*250*8mm steel plate. The bottom of the irregular support is welded and fixed to the upper surface of the base plate.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: This utility model eliminates the original design of the front tripod and rear wheel frame of the suspension mechanism. Instead, a special-shaped support is designed in the original positions of the front tripod and rear wheel frame. The lower end of the special-shaped support is directly fixed to the double-row round steel beams on the construction site through a customized base plate and U-shaped clamp bolts, realizing the installation and erection of the suspension mechanism. This solves the problem that the double-row round steel beam structure on the roof cannot be used to install the suspended basket suspension mechanism for curtain wall decoration construction. Moreover, the overall height of the front and rear supports can be adjusted. When the parapet wall at the front of the roof is higher than the conventional horizontal beam, the height of the front and rear supports can be increased to allow the horizontal beam to be installed higher than the parapet wall.

[0024] For the standard support structure of the existing external wall suspended platform device suspension mechanism, please refer to Figure 5 and Figure 6 The suspended platform 6 is supported on the roof via a front tripod 8 and a rear wheel frame 9 below the crossbeam 1. A counterweight 10 is added to the rear wheel frame 9 to enable the platform to operate. However, when there is no floor on the roof, the front tripod 8 and rear wheel frame 9 cannot be installed. Therefore, this utility model eliminates the original design of the front tripod 8 and rear wheel frame 9 and designs a front and rear support for the roof with a double-row round steel beam 7 structure, realizing the unconventional installation of the external wall suspended platform 6. This utility model will be further explained below.

[0025] Example: An unconventional installation device for an external wall suspended platform 6, see [link / reference] Figures 1 to 4The system includes a suspension mechanism and a suspended platform 6. The suspension mechanism consists of a crossbeam 1, an upper column 5, and front and rear supports. The front and rear supports consist of a movable adjusting rod 2, a special-shaped support 3, and U-shaped clamp bolts 4. The upper end of the special-shaped support 3 is fitted onto the lower end of the movable adjusting rod 2. The special-shaped support 3 and the movable adjusting rod 2 are fixedly connected by a positioning pin. The upper end of the movable adjusting rod 2 is fixedly connected to the crossbeam 1. A base plate 31 is welded to the bottom surface of the special-shaped support 3. A triangular reinforcing plate 33 for reinforcement is welded between the special-shaped support 3 and the base plate 31. The base plate 31 is provided with mounting holes 34 for installing U-shaped clamp bolts 4. The base plates 31 of the front and rear supports are respectively fixed to the double-row round steel beams 7 at the construction site by U-shaped clamp bolts 4. This utility model eliminates the original design of the front tripod 8 and rear wheel frame 9 of the suspension mechanism. Instead, a special-shaped support 3 is designed in the original positions of the front tripod 8 and rear wheel frame 9. The lower end of the special-shaped support 3 is directly fixed to the double-row round steel beam 7 on the construction site through a customized base plate 31 and U-shaped clamp bolts 4, so as to realize the installation and erection of the suspension mechanism. Moreover, the special-shaped support 3 can adjust the overall height of the front and rear supports. When the parapet wall at the front of the roof is higher than the conventional crossbeam 1, the height of the front and rear supports can be increased to allow the crossbeam 1 to be installed higher than the parapet wall.

[0026] Since the bottoms of both the front and rear supports are directly fixed to the double-row circular steel beams 7 using U-shaped clamp bolts 4 to form supporting load-bearing parts, the rear support at the rear end of the crossbeam 1 does not require a counterweight, making its installation and use simpler. The installation and erection method is as follows:

[0027] First, the original front tripod 8 and rear wheel frame 9 are removed, and the special irregular support 3 of this utility model is adopted;

[0028] Secondly, the base plate 31 of the irregular support 3 is fixed to the double-row round steel beam 7 structure using two sets of M18 U-type clamp bolts 4;

[0029] Then, the movable adjustment rod 2 is vertically installed inside the square tube column of the front and rear irregular support 3, and after the movable adjustment rod 2 is adjusted to the set height, it is fixed to the irregular support 3 by the positioning pin;

[0030] Finally, install the crossbeam 1 and the vertical beam to complete the installation of the suspension mechanism bracket.

[0031] It should be noted that when installing clamp bolts and irregular supports 3 at the location of the double-row round steel beams 7 on the roof of the main workshop, the lessee of the suspended platform 6 should set up a scaffolding operating platform or use a mobile scissor truck as a passage for the installation, daily maintenance and inspection personnel of the suspended platform 6.

[0032] Because some parts of the roof edge have parapet walls that would obstruct the extension of the crossbeam 1, in order to adjust the height of the crossbeam 1, the irregular support 3 and the movable adjusting rod 2 are provided with pin holes 32 that match the positioning pins. There are multiple pin holes 32 on the irregular support 3, and the multiple pin holes 32 are evenly distributed along the length of the irregular support 3. Through the design of the pin holes 32, the movable adjusting rod 2 can be adjusted according to its installation height as needed to achieve the overall height adjustment of the crossbeam 1. In order not to affect the support strength of the irregular support 3, the most preferred solution is that the interval of the pin holes 32 is not less than 200 mm.

[0033] The U-shaped clamp bolt 4 is an M18 U-shaped bolt, and its inner diameter matches the diameter of the double-row round steel beam 7. The two ends of the U-shaped clamp bolt 4 are equipped with locking nuts and washers. The two ends of the U-shaped clamp bolt 4 are fixed to the base plate 31 of the irregular support 3 by locking nuts. After the clamp bolt is fixed, the irregular support 3 can be tightly clamped and fixed to the round steel beam 7. Since both the front and rear supports are irregular supports 3, after being fixed to the double-row round steel beam 7 by U-shaped clamp bolt 4, a stable square support structure can be formed, which can prevent the clamp bolt from rotating around the round steel beam 7.

[0034] The irregular support 3 has two sets of U-shaped clamp bolts 4 on its base plate 31. The two sets of U-shaped clamp bolts 4 are located on the left and right sides of the irregular support 3, respectively. The force on the irregular support 3 can be evenly transmitted to the base plate 31 and then to the round steel beam 7 through the U-shaped clamp bolts 4, so that the irregular support 3 is not easy to deviate.

[0035] Since the crossbeam 1 is a multi-segment splicing assembly structure, there will be certain installation errors between the front and rear supports. At the same time, there are also certain installation errors in the installation of the double-row round steel beams 7, resulting in non-standard spacing. Therefore, in order to ensure the verticality of the installation of the irregular support 3, the installation hole 34 for installing the U-shaped clamp bolt 4 is designed as an elongated hole, with its length direction consistent with the length direction of the round steel beam 7. This allows the irregular support 3 to have a certain amount of adjustment in the length direction of the round steel beam 7, so as to compensate for the tilting problem of the irregular support 3 caused by the installation error, and so that the force of the irregular support 3 can be better vertically transmitted to the round steel beam 7.

[0036] To ensure the strength of the irregular support 3, as a preferred embodiment, the irregular support 3 is an 80*80*3.75mm square tube column, the base plate 31 is a 250*250*8mm steel plate, and the bottom of the irregular support 3 is welded and fixed to the upper surface of the base plate 31.

Changes and improvements to this utility model are possible without exceeding the concept and scope specified in the appended claims. Therefore, the content of this specification should not be construed as a limitation of this utility model.
