[0002] In construction scenarios, it is often necessary to set up high-altitude construction platforms to meet the needs of personnel construction or tool placement, such as operating platforms for pouring bridge piers in highway and railway bridge construction, construction platforms for installing clamps for bridge piers, and tower crane maintenance platforms in the construction industry. These construction platforms usually use aerial platforms or scaffolding for construction, which has low construction efficiency and high safety risks. In addition, because aerial platforms need to be rented all the time, the construction cost is also very high. Considering the safety of construction, some projects will also customize a high-altitude construction platform with a fixed inner diameter according to the current construction scene. However, such a construction platform can only meet one-time use requirements or be reused only in customized scenarios because the inner diameter cannot be adjusted. The narrow scope of application leads to low turnover times and high construction costs. Therefore, there is an urgent need for a variable diameter construction platform with adjustable inner diameter. Utility Model Content

[0003] The embodiments of this specification provide a construction platform with a variable diameter, which can take into account the inconsistent requirements for the inner diameter of the construction platform in different construction scenarios, thereby reducing the construction cost of the project.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of this specification will be described clearly and completely below in conjunction with the drawings in the embodiments of this specification.

[0021] The terms "first", "second", "third", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0022] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present specification. Various processes or components may be appropriately omitted, substituted or added to each example.

In addition, features described with respect to some examples may be combined in other examples.

[0023] See also Figure 1 or Figure 2 , Figure 1 and Figure 2 A schematic structural diagram of a variable diameter construction platform provided in an embodiment of this specification is shown.

[0024] like Figure 2 As shown, the system may at least include a platform base 1, a hollow portion 2 is provided in the center of the platform base 1, and a plurality of adjustment platforms 3 are provided around the hollow portion 2 on the platform base 1, which can be relatively displaced with the platform base 1 in a direction parallel to the platform base 1 and a direction perpendicular to the platform base 1 to change the size of the overlapping area between the platform base 1 and the hollow portion 2 and the height difference between the platform base 1 and the platform base 1.

[0025] It is understandable that during construction, the internal construction column is inserted into the platform base 1 from the hollow part 2 in the middle of the platform base 1, and the construction personnel can stand on the platform base 1 or the adjustment platform 3 to perform construction operations on the internal construction column. Because the diameters of different internal construction columns are different, the required sizes of the hollow areas inside the platform base 1 are also different. The utility model adjusts the adjustment platform 3 to perform relative displacement in a direction parallel to the platform base 1 to change the size of the hollow area inside the platform base 1. It is understandable that if the aperture of the construction platform is relatively small, multiple adjustment platforms 3 will inevitably need to overlap each other during adjustment. Because the heights of the multiple adjustment platforms 3 relative to the platform base 1 are the same, there will be a phenomenon of collision between the multiple adjustment platforms 3. In order to avoid this situation, the utility model supports adjusting the height of the adjustment platform 3 so that the multiple adjustment platforms 3 can be staggered to avoid collision.

[0026] It is understandable that the height of the adjustment platform 3 may also be fixed, and two adjacent adjustment platforms 3 may be set to staggered fixed heights to avoid collision.

[0027] See also Figure 1 As shown, in one embodiment of the present specification, the platform base 1 is provided with a plurality of height adjustment devices 4 which are arranged perpendicular to the direction of the platform base 1 and whose number is the same as the adjustment platform 3, and the tops of the plurality of height adjustment devices 4 are respectively provided with a plurality of tracks 5 which are arranged parallel to the direction of the platform base 1, and the bottoms of the plurality of adjustment platforms 3 are respectively slidably connected to the plurality of tracks 5.

[0028] It can be known that in order to achieve height adjustment of the adjustment platform 3 in a direction perpendicular to the platform base 1, a height adjustment device 4 can be set on the platform base 1, and the height adjustment device 4 can be a height adjustment bolt, and the height of the track 5 and the adjustment platform 3 can be adjusted by screwing in or out the bolt on the platform base 1. The construction personnel can first adjust the height adjustment device 4 on the ground to ensure that multiple adjustment platforms 3 will not collide with each other during horizontal displacement, and then hang the construction platform for use. Preferably, the height adjustment device 4 can also be two telescopic vertical rods, and the adjustment components of the adjustment vertical rods are installed on the upper surface of the platform base 1, which is convenient for workers to move the adjustment platform 3 in the air to change the inner diameter of the construction platform and adjust the height of the adjustment platform 3 at the same time.

[0029] It is understandable that rollers can be installed at the bottom of the adjusting platform 3 to make it easier to move the adjusting platform 3 in the horizontal direction. Buckles can also be set on the rollers to facilitate fixing the adjusting platform 3 after it is rolled to a suitable position. In addition, in order to allow construction personnel to have a gripping point when pushing the adjusting platform 3 and avoid directly gripping the adjusting platform 3 and causing their fingers to be crushed by the operating platform, an operating handle can be set on the adjusting platform 3. The operating handle can be folded and retracted into a hidden groove of the operating handle set on the adjusting platform 3 to avoid bumps and collisions caused by the operating handle being vertically erected on the adjusting platform 3 after the adjustment is completed.

[0030] It is understandable that if the height of the track 5 is too high, the height difference between the adjustment platform 3 and the platform base 1 will also be large, which will affect the walking experience of the construction workers on the construction platform. Therefore, a groove can be set on the platform base 1 to accommodate the track 5, so that the height difference between the adjustment platform 3 and the platform base 1 can be smaller.

[0031] It is understandable that if the adjusting platform 3 needs to move more toward the hollow part 2, the width of the overlapping area between the adjusting platform 3 and the hollow part 2 in the displacement direction of the adjusting platform 3 toward the hollow part 2 will exceed half the width of the adjusting platform 3. Because the adjusting platform 3 is supported by the track 5, the adjusting platform 3 may be unstable. To solve this problem, the track 5 can be extended into the hollow part 2 to make the adjusting platform 3 more stable. Internal construction columns, such as bridge piers and tower cranes, will be inserted into the inner diameter of the construction platform. The longer the track 5, the smaller the diameter of the internal construction columns that can be inserted into the hollow part 2 of the construction platform. Therefore, the telescopic track 5 can be used to increase the placement stability of the adjusting platform 3 without reducing the maximum inner diameter value of the internal construction columns that can be inserted into the construction platform.

[0032] See also Figure 2 As shown, in one embodiment of the present specification, a recessed area 6 is provided on a side of the adjustment platform 3 facing the hollow portion 2 .

[0033] It is understandable that because the usage scenarios of the construction platform are diverse, the internal construction columns may be circular, square, regular hexagonal, etc., so a recessed area 6 can be set on the adjustment platform 3 toward the hollow part 2 to meet the needs of better adapting to internal construction columns of different shapes, so that the safety of the construction platform can be improved.

[0034] See also Figure 2 As shown, in one embodiment of the present specification, the recessed area 6 is arc-shaped.

[0035] It is understandable that when the internal construction column is circular or polygonal, the arc-shaped adjustment platform 3 facing the hollow portion 2 can reduce the gap between the adjustment platform 3 and the internal construction column to a greater extent, making construction workers safer during construction.

[0036] See also Figure 2 As shown, in one embodiment of the present specification, the construction platform further includes a plurality of extension plates 8, and the other three sides of the adjustment platform 3 except one side facing the hollow portion 2 are provided with extension plate mounting structures 7 for mounting the extension plates 8.

[0037] It is understandable that when the sizes of construction platforms required for construction projects are significantly different, although it is possible to use all construction platforms of the same size, this may result in the need to rent larger and more transport vehicles and cranes with greater lifting power, increasing the cost of renting machines. Therefore, several construction platforms of different specifications can be fixedly set up so that the construction platforms can be used while the cost of renting machines is also low. Considering that the specifications of the construction platforms are different, the sizes of the adjustment platforms 3 required will also be inconsistent. Therefore, an extension plate mounting structure 7 can be added on both sides of the adjustment platform 3 so that the adjustment platform 3 can be used on construction platforms of different specifications. The extension plate mounting structure 7 can be a bolt mounting hole.

[0038] In addition, in order to make the adjustment platform 3 more convenient to move when performing horizontal displacement, rollers are generally installed at the bottom of the adjustment platform 3. After the rollers are installed, the overall height of the adjustment platform 3 is higher. The tall and long adjustment platform 3 occupies a larger area during transportation. If the adjustment platform 3 has detachable extension plates 8 on both sides, the length of the adjustment platform 3 can be reduced after the extension plates 8 are removed. The height of the detached extension plates 8 is lower, and the volume occupied after stacking is smaller. Therefore, the use of the extension plates 8 can also reduce the requirements for the transport vehicle, making the adjustment platform 3 more convenient to transport.

[0039] See also Figure 2 As shown, in one embodiment of the present specification, the extension plate mounting structure 7 is a rotating mounting structure for mounting the extension plate 8 and realizing a rotational connection between the extension plate 8 and the side edge of the adjustment platform 3 .

[0040] It is understandable that because there is a height difference between the adjustment platform 3 and the platform base 1, and there will be a height difference after multiple adjustment platforms 3 are overlapped, it is not comfortable for construction workers to walk on the construction platform, and they may be bumped by the adjustment platform 3. Therefore, a rotatably connected extension plate 8 can be set on the outermost side of the adjustment platform 3. Because it is rotatable, the side of the extension plate 8 away from the adjustment platform 3 will automatically rotate downward to contact the platform base 1 of the lower layer, so that a small slope will appear between the adjustment platform 3 and the platform base 1 to improve the comfort of construction workers walking on the construction platform and prevent construction workers from being bumped. It is understandable that the extension plate 8 can be bolted to the outside of the adjustment platform 3 until the length of the adjustment platform 3 meets the use requirements, and then the rotatably connected extension plate 8 can be installed on the outside of the extension plate 8. This can meet the needs of lengthening the adjustment platform 3 and reducing the height difference between the adjustment platform 3 and the platform base 1.

[0041] See also Figure 1 As shown, in one embodiment of the present specification, a buffer structure 9 is disposed on the periphery of the adjustment platform 3 .

[0042] It is understandable that when adjusting the adjustment platform 3 for horizontal displacement, the construction personnel may forget to adjust the height of the adjustment platform 3, resulting in collisions between the adjustment platforms 3. Violent collisions may cause the construction platform to shake and cause danger, and may also cause the adjustment platform 3 to slide off the track 5 and damage the rollers, etc. Therefore, a buffer structure 9 is set outside the adjustment platform 3 to reduce the buffer force and prevent damage. The buffer structure 9 is a layer of sponge wrapped around the adjustment platform 3.

[0043] See also Figure 2 As shown, in one embodiment of the present specification, a plurality of position-limiting member mounting holes 10 are provided on the platform base 1 at intervals on a projection surface of a path where the adjustment platform 3 is parallel to the platform base 1 and undergoes relative displacement.

[0044] It is understandable that after the adjustment platform 3 is adjusted to a suitable position, the construction workers may use excessive force in the horizontal direction during the construction process, such as pushing the ground too hard, causing the adjustment platform 3 to move horizontally again, resulting in the adjustment platform 3 and the internal construction column moving away from each other, which puts the construction workers at risk of safety. Therefore, a limiter installation hole 10 may be provided on the platform base 1. After the position of the adjustment platform 3 is adjusted, a limiter is installed to prevent the adjustment platform 3 from sliding again. The limiter installation hole 10 may be a bolt installation hole provided at intervals on the platform base 1.

[0045] See also Figure 1 As shown, in one embodiment of the present specification, a protective structure 11 is provided around the periphery of the platform base 1 , and a door structure 12 is provided on at least one side of the protective structure 11 .

[0046] It is understandable that, because the construction platform is used for high-altitude operations, in order to further ensure the safety of personnel, a protective structure 11 should be set around the periphery of the construction platform. The protective structure 11 can be a protective railing or a protective plate. If a protective railing is installed, a protective plate of a certain height can be installed at the bottom of the protective railing to prevent the feet of the construction personnel from sliding out of the construction platform from the platform base 1. In addition, installing a protective plate in the tower crane maintenance platform can also prevent people from climbing.

[0047] It is understandable that, in order to facilitate the construction workers to enter and exit, a door structure 12 can be provided on one side of the protective structure 11 to perform the door opening and closing operations.

[0048] See also Figure 1 As shown, in one embodiment of the present specification, it is characterized in that the construction platform also includes two telescopic vertical rods 13 respectively connected to the opposite ends of the platform base 1 and a cross bar 14 with two ends respectively connected to the tops of the two telescopic vertical rods 13, and both ends of the cross bar 14 are provided with lifting ears 15.

[0049] It is understandable that although some construction platforms are supported by setting up support frames, when the construction platform can be suspended, setting up a hanging structure is simpler and more time-saving than building a support frame. Therefore, vertical rods 13 can be symmetrically set at both ends of the construction platform, and horizontal rods 14 connecting the vertical rods 13 can be used to suspend the construction platform.

[0050] It can be understood that for a square construction platform, a vertical bar 13 can be set on each side, and two cross bars 14 can be used to connect the vertical bars 13 on opposite sides. This will be more stable than setting only one cross bar. The two cross bars 14 can be cross-shaped or set in parallel. However, if set in parallel, the distance between the two parallel cross bars 14 should be smaller than the maximum cross-sectional width of the internal construction column to facilitate hanging.

[0051] It is understandable that different projects require different construction heights and the distances from the tops of the internal construction columns, so the retractable vertical rods 13 set at both ends of the construction platform can better meet the needs of different scenarios and have a wider range of applications.

[0052] It is understandable that, in order to facilitate the hanging of the construction platform, lifting ears 15 can be provided at both ends of the cross bar 14 to facilitate the hooking of the lifting equipment.

[0053] The following specifically describes the use of the utility model by applying the above-mentioned variable-diameter construction platform to the scene of the bridge hoop construction platform, as follows:

[0054] Step 1: Adjust the height of the adjustment platform 3 to ensure that the adjustment platform 3 does not collide with each other when sliding, then hang the wire rope on the construction platform lug 15, and use a crane to lift it onto the pier column;

[0055] Step 2: Use a climbing vehicle to send the construction workers to the construction platform, and the construction workers close the door on the side of the guardrail;

[0056] Step 3: The construction personnel adjust the height of the adjustment platform 3 to avoid collision between adjacent adjustment platforms 3, and then push the operating handle to move the adjustment platform 3 toward the pier column so that the adjustment platform 3 is in close contact with the pier column;

[0057] Step 4: After the clamp is installed, the construction workers use the aerial platform to return to the ground;

[0058] Step 5: Use a crane to lower the construction platform.

[0059] The embodiments described above are merely preferred embodiments of this specification and are not intended to limit the scope of this specification. Without departing from the design spirit of this specification, various modifications and improvements made to the technical solutions of this specification by ordinary technicians in this field should fall within the scope of protection determined by the claims of this specification.
