Description

Technical Field

[0001] The present invention relates to the technical field of steel cage support, and in particular to a rotatable steel cage support device and a method thereof. Background Art

[0002] Steel cages, as important structural parts in building and bridge construction, are made of steel bars twisted into a mesh cylindrical shape, and are mainly used to enhance the tensile strength of concrete structures. Steel cages play a vital role in pile foundation construction, bridge and culvert construction, and foundation construction of high-rise buildings. In the absence of a supporting structure, steel cages are easily affected by external forces during hoisting and transportation, causing deformation, which affects the construction quality and overall stability of the project.

[0003] The existing supports include split internal support devices and integrated internal support devices. During the installation and disassembly process of the split internal support device, it is necessary to enter the interior of the steel cage for installation and disassembly, which makes the installation and disassembly process very troublesome, and it is even more difficult to disassemble after the steel cage is vertically hoisted. Although the use of an internal support device can solve the disassembly problem to a certain extent, its installation process is carried out after the steel cage is manufactured, which still cannot avoid the need to enter the interior of the steel cage for installation. At the same time, the existing integrated internal support device is driven by pneumatic pressure, which makes the support mode not single and cannot be adjusted according to the condition of the steel cage. In addition, the support may become loose when the local stress increases during the hoisting and adjustment of the steel cage posture. At the same time, the existing integrated internal support device is not easy to be used in turnover because it is not removable. Summary of the invention

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Figure 3 FIG. 1 shows a schematic diagram of the exploded structure of the support device disclosed in the embodiment of the present invention. Generally speaking, in order to ensure the stability of the support, at least three inner support structures 1 ( Figure 3 The structure in the figure is used to display the structure. During use, it is necessary to select an appropriate number of internal support structures according to the actual situation 1).

[0039] like Figure 2 As shown, the inner support structure 1 is distributed inside the steel cage 5 along the length direction of the steel cage 5 to support the inside of the steel cage 5 .

[0040] like Figures 3-4 As shown, the internal support structure 1 includes a load-bearing ring 11 and a reinforcing rib 111 arranged inside the load-bearing ring 11, at least six connecting sleeves a112 are evenly arranged in the axial direction of the load-bearing ring 11, and a connecting sleeve b113 is coaxially arranged on the reinforcing rib 111 at the axis of the load-bearing ring 11.

[0041] The above-mentioned connecting sleeve a112 and the connecting sleeve b113 are both provided with internal threads for realizing detachable connection. Meanwhile, the connecting sleeve a112 and the connecting sleeve b113 can also adopt other detachable connection methods, such as using snaps or bolts.

[0042] In this embodiment, it is preferred to achieve detachable connection by providing threads.

[0043] The connecting sleeve a112 is detachably connected to the telescopic strut 12, wherein the telescopic struts 12 connected to different connecting sleeves a112 can adjust their lengths respectively, the telescopic strut 12 comprises a hydraulic rod 122, the end of the hydraulic rod 122 is provided with a connecting end 124, the connecting end 124 is detachably connected to the connecting sleeve a112, an extension rod 123 is connected to the head end of the hydraulic rod 122, wherein the extension rod 123 is connected to the connecting end 124, and the connecting end 124 is used to connect to the main reinforcement 51.

[0044] The number of telescopic struts 12 is set according to the number of connecting sleeves a112. Generally speaking, the more telescopic struts 12 there are, the better the supporting effect will be. However, the cost and weight of the structure will also increase. Therefore, it needs to be set according to actual conditions. In this embodiment, the number of telescopic struts 12 is not less than six.

[0045] It should be noted that the hydraulic rod 122 is also connected to a hydraulic driving structure, and the hydraulic driving structure is used to realize synchronous driving of the hydraulic rod 122 or asynchronous driving of the hydraulic rod 122 .

[0046] The above synchronous drive and asynchronous drive are defined as:

[0047] Synchronous drive: All hydraulic rods 122 extend or shorten synchronously.

[0048] Asynchronous drive: The hydraulic rod 122 is extended or shortened according to the settings.

[0049] In the supporting mode, the inner supporting structure 1 controls the head end of the hydraulic rod 122 to extend, driving the extension rod 123 to drive the connecting end 124 to contact the main reinforcement 51 of the steel cage 5. At the same time, the connecting end 124 is clamped together with the main reinforcement 51 of the steel cage 5 to form a fixation with the steel cage 5.

[0050] In the recovery mode, the inner support structure 1 controls the head end of the hydraulic rod 122 to retract, thereby driving the extension rod 123 to separate the connecting end 124 from the main reinforcement 51 of the reinforcement cage 5 .

[0051] At the same time, in order to facilitate turnover, multiple detachable structures are used, including:

[0052] The connecting end 124 is threadedly connected to the connecting sleeve a112.

[0053] The intermediate connecting rod 2 is threadedly connected to the connecting sleeve b113.

[0054] The end connecting rod 3 is threadedly connected to the connecting sleeve b113.

[0055] The benefits of doing this are:

[0056] 1. Easy to install. The inner support structure 1 can be decomposed into multiple substructures through the threaded connection between the intermediate connecting rod 2 and the connecting sleeve b113. During the installation process, they can be installed synchronously according to the construction progress of the steel cage 5, effectively reducing the difficulty of installation.

[0057] 2. The inner supporting structure 1 can be decomposed into multiple substructures by threading the middle connecting rod 2 with the connecting sleeve b113. At the same time, the connecting end 124 is threadedly connected to the connecting sleeve a112, so that the telescopic support rod 12 can be separated from the load-bearing ring 11. The end connecting rod 3 is threadedly connected to the connecting sleeve b113, so that the end connecting rod 3 can be separated from the connecting sleeve b113, which makes it easier to place and transport during the transfer process, effectively improving the turnover efficiency.

[0058] like Figure 1 As shown, after the inner support structure 1 and the steel cage 5 are installed, the outer support structure 4 is first installed on a transportation vehicle, and then the steel cage 5 is hoisted onto the outer support structure 4.

[0059] The outer support structure 4 includes a base 41, on both sides of the top of which are respectively provided with vertical support rods 42, a clamping plate 43 is provided between the two vertical support rods 42, and a clamping groove 431 is provided on the clamping plate 43. The shape of the clamping groove 431 is adapted to the shape of one end of the end connecting rod 3 close to the outer support structure 4, and the cross-section of the end of the end connecting rod 3 close to the outer support structure 4 is rectangular.

[0060] After being hoisted down, the end connecting rod 3 is placed into the slot 431 , and the slot 431 supports and protects the steel cage 5 installed with the inner supporting structure 1 .

[0061] In order to achieve the protective effect, the size of the outer support structure 4 should be larger than the cross-section of the steel cage 5 so that the steel cage 5 will not collide with adjacent steel cages 5 and other contact surfaces during the use of the outer support structure 4.

[0062] The base 41 can be fixed on a transport vehicle or on the ground in a fixed installation manner. When multiple steel cages 5 need to be stacked, the adjacent external support structures 4 in the horizontal or vertical direction can also be connected and fixed by bolts or other fixing methods to enhance the stability during transportation or storage.

[0063] like Figure 5 As shown, a supporting method for a rotatable steel cage supporting device comprises the following steps:

[0064] S1, calculate the corresponding number of internal support structures 1, support positions, and support postures according to the parameters of the steel cage 5.

[0065] The parameters of the steel cage 5 include material parameters, size parameters and shape parameters of the main reinforcement 51 .

[0066] The process of calculating the number and support position of the internal support structure 1 includes:

[0067] Using the parameters of the steel cage 5 mentioned above, a three-dimensional model of the steel cage 5 is established using finite element analysis software;

[0068] According to engineering experience and design requirements, a preliminary inner support structure 1 support point position is set inside the steel cage 5;

[0069] Apply boundary conditions and loads to the steel cage 5 model. The boundary conditions include the fixing method and constraint conditions of the steel cage 5. The loads include deadweight and external loads.

[0070] Use finite element analysis software to simulate and analyze the steel cage 5 model;

[0071] According to the simulation results, the stress distribution and deformation inside the steel cage 5 are analyzed;

[0072] If there is excessive stress or deformation in some areas, adjust the position and number of internal support points to improve the stress state of these areas;

[0073] Through multiple iterations and optimizations, the number and support positions of the internal support structures 1 are obtained.

[0074] The support posture calculation process includes:

[0075] According to the position of the integral inner support point, the shape parameters of the main reinforcement 51 at the corresponding position are obtained;

[0076] Perform feature recognition on the shape parameters to obtain the elongation of the hydraulic rod 122;

[0077] The elongations of all the hydraulic rods 122 of a single internal support structure 1 constitute a group of support postures, and multiple groups of support postures constitute a support posture set.

[0078] S2, calculate the pre-support load and transportation support load of the inner support structure 1 on the steel cage 5.

[0079] Among them, the pre-support load is used in the process of welding the steel cage 5, and the transport support load is used in the process of transporting the steel cage 5.

[0080] The pre-support load and the transport support load are both simulated by finite element analysis, wherein the pre-support load is obtained by a welding simulation process, and the transport support load is obtained by a transport simulation process.

[0081] S3, connecting the inner support structure 1 to the main reinforcement 51 of the reinforcement cage 5 for pre-support.

[0082] This step is a welding process, including controlling the head ends of different hydraulic rods 122 to extend according to the support posture, driving the extension rod 123 to drive the connecting end 124 to contact the main reinforcement 51 of the steel cage 5, and at the same time, the connecting end 124 is clamped together with the main reinforcement 51 of the steel cage 5 to form a fixation with the steel cage 5. At the same time, according to the calculated pre-support load, the hydraulic rod 122 is driven to continue to extend to apply the pre-support load to the steel cage 5.

[0083] The function of the pre-support load is to prevent the steel cage 5 from being deformed during the welding process, thereby improving the manufacturing quality of the steel cage 5 .

[0084] S4, during the welding process of the steel cage 5, the intermediate connecting rods 2 are installed in sequence according to the welding length of the steel cage 5 to connect the adjacent inner supporting structures 1 together.

[0085] This step is a segmented installation connection, and the inner support structure 1 can be installed simultaneously during the process of making the steel cage 5. The installation is convenient, and there is no need to use the method of installing inside the steel cage 5 later, which effectively improves efficiency.

[0086] S5, after the welding of the steel cage 5 is completed, the end connecting rod 3 is installed at the inner supporting structure 1 near the first and last ends of the steel cage 5.

[0087] S6, applying a transport support load to the steel cage 5, hoisting the steel cage 5 onto the outer support structure 4, and fixing the position of the steel cage 5 by using the clamping slot 431.

[0088] The hydraulic rod 122 is driven to continue to extend according to the calculated pre-support load, so as to apply a transport support load to the steel cage 5 .

[0089] The beneficial effects of the present invention are:

[0090] 1. A hydraulic telescopic support rod 12 is used. At the same time, the length of a single telescopic support rod 12 can be freely adjusted, and the support can be adaptively adjusted according to the condition of the steel cage 5, so as to achieve the effect of stable support according to the condition of the steel cage 5.

[0091] 2. The detachable structure is not only convenient for the installation of the support device, but also for storage, thus improving the convenience of turnover use.

[0092] 3. The structure of inner support plus outer support is adopted. The two support structures cooperate with each other to isolate two adjacent steel cages 5 from each other during the transportation of the steel cages 5, so as to avoid damage caused by collision during transportation.

[0093] It should be noted that the specific model and specifications of the hydraulic rod 122 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0094] The power supply and principle of the hydraulic rod 122 are clear to those skilled in the art and will not be described in detail here.

[0095] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
