Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a vertical support system bearing column, an installation guide platform and an installation method. Background Art

[0002] The vertical support system bearing column usually refers to the reverse construction method of vertical support system in which steel columns are inserted into pile foundations. It is a key component during the implementation of the reverse construction of the foundation pit. These bearing columns are mainly used to bear the deadweight of the structural beams and slabs, the road surface covering and related construction loads to ensure the structural stability and safety during the construction process. During the construction stage of the cover-excavation reverse construction method, only one steel column and column pile are set at each structural column position to bear the vertical loads such as the deadweight of the structure and construction loads in the corresponding range of each layer of the slab. This form is simple and direct, and is easy to construct and manage. If conditions permit, the form of one column and multiple piles can also be used to increase the bearing capacity and stability by increasing the number of pile foundations. This form is suitable for projects with large loads or poor geological conditions.

[0003] The supporting stability and bearing capacity of the bearing column in the existing technology are the core elements to ensure the quality and safety of the reverse construction project. During construction, as the depth of the foundation pit increases, the verticality of the column pile directly affects the bearing capacity and stability of the vertical support system, and is an important control factor in construction. The construction technology of bored piles or rotary piles is relatively mature, and the verticality of the pile body is relatively easy to control; and during the reverse construction process, the steel pipe column is fixed by the bored pile hole and freely hangs in the pile hole. There are insufficient constraints around it, and its own stability is poor. It is easily affected by the impact disturbance during the concrete pouring process, and the verticality is difficult to achieve high-precision control.

DETAILED DESCRIPTION

[0042] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1, this embodiment provides a vertical support system bearing column, such as Figure 1 and Figure 5 As shown, it includes: a bearing column 1, a plurality of bearing columns 1 are provided, a docking pile 2 is provided between two adjacent bearing columns 1, the axial ends of the docking pile 2 are respectively insertion ends 22, and an expansion part is provided at the middle position of the docking pile 2, the two insertion ends 22 are respectively inserted into the opposite ends of the two adjacent bearing columns 1, and the axial ends of the expansion part are respectively against the opposite side walls of the two adjacent bearing columns 1, where the diameter of the expansion part is equal to the diameter of the bearing column 1; the axial ends inside the bearing column 1 are expansion openings for docking the insertion end 22, and the inner diameter of the expansion opening is equal to the outer diameter of the insertion end 22; the bearing column 1 is provided with a reduction opening located between the two expansion openings axially, and the inner diameter of the reduction opening is equal to the inner diameter of the insertion end 22, so as to ensure that after the insertion end 22 is inserted into the end of the bearing column 1, seamless docking is achieved to avoid the existence of a large gap that causes the bearing column 1 to be tilted after docking.

[0044] In order to prevent the insertion end 22 from being separated from the inner end of the bearing column 1, the docking pile 2 and the bearing column 1 need to be stably spliced ​​to form a complete vertical support structure.

[0045] Specifically, a plurality of through holes are provided on the radial side wall of the insertion end 22, a flip block is provided on the inner wall of the through hole, and a convex block 21 is provided on the side wall of the flip block away from the axis of the insertion end 22, and a magnet block is embedded in the convex block 21, such as Figure 2 and Figure 4 As shown, under normal conditions, the magnetic poles of the magnet blocks of two adjacent protrusions 21 are different from each other, and the magnet blocks are attracted to each other and close together, which can drive multiple flip blocks to flip around the rotation position toward the axis of the insertion end 22. In this way, the insertion end 22 can be inserted into the enlarged opening at the end of the supporting column 1 without any resistance.

[0046] like Figure 1 and Figure 3As shown, the reinforcement is inserted into the docking pile 2, and the radial outer walls at both axial ends of the load-bearing column 1 are provided with a plurality of through holes 11 for docking protrusions 21. When the enlarged opening at the end of the load-bearing column 1 and the insertion end 22 are plugged into each other, the reinforcement is inserted into the docking pile 2. During the insertion process, the radial outer wall of the reinforcement pushes the plurality of rotating and close-together flip blocks to rotate in the opposite direction, and the protrusion 21 is pushed out from the through hole 1 and stuck into the through hole 2 11. The protrusion 21 is stuck in the through hole 2 11 to prevent the insertion end 22 from sliding out of the enlarged opening at the end of the load-bearing column 1.

[0047] Specifically, the first example of a reinforcement member: Figure 3 As shown, the reinforcement includes multiple hollow steel sleeves 3 and multiple threaded steel bars 31. The multiple hollow steel sleeves 3 are coaxial and evenly spaced. The multiple threaded steel bars 31 are arranged in a ring structure and penetrate the axial edge side walls of the multiple hollow steel sleeves 3 to form a columnar pile body. The axial ends of the threaded steel bars 31 are respectively flush with the ends of the uppermost and lowermost hollow steel sleeves 3 that are away from each other. The outer diameter of the hollow steel sleeve 3 is equal to the inner diameter of the insertion end 22. Figure 3 As shown, a radially distributed hanging beam 32 is fixed to the inner wall of the uppermost hollow steel sleeve 3. The entire pile body can be lifted by hanging it on the hanging beam 32 using the lock of the lifting equipment. The pile body is inserted from the enlarged opening at the upper end of the uppermost bearing column 1, and then enters the narrowed opening of the bearing column 1. It continues to slide down, passes through the insertion end 22, and enters from the enlarged opening at the upper end of the lower bearing column 1 again, and continues to slide down along the narrowed opening of the lower bearing column 1, and finally lowered to the enlarged opening at the lower end. The length of the entire pile body is equal to the sum of the length of the two bearing columns 1 and the axial length of the enlarged part, ensuring that the axial ends of the pile body do not extend out of the enlarged openings of the upper and lower bearing columns 1.

[0048] Moreover, the pile body composed of the hollow steel sleeve 3 and multiple threaded steel bars 31 is a hollow structure in the axial direction. The pile body is inserted into the bearing column 1 and the insertion end 22. The concrete can be corrected through the hollow structure of the uppermost hollow steel sleeve 3. The concrete flows downward along the hollow structure and fills the entire hollow structure, so as to enhance the bearing strength of the entire pile body.

[0049] like Figure 6 As shown, the second example of the reinforcement member: the reinforcement member includes an expansion support pile 33, the upper end of the expansion support pile 33 is provided with an expansion end, the expansion support pile 33 is inserted into the insertion end 22, the expansion end is located on the upper end surface of the insertion end 22, and the upper end surface of the expansion end is provided with a semicircular hook 34. Figure 6As shown, the outer diameter of the enlarged end is equal to the outer diameter of the insertion end 22, and the outer diameter of the lower end of the expansion support pile 33 is equal to the inner diameter of the insertion end 22. When the insertion end 22 is inserted into the enlarged opening at the end of the load-bearing column 1, the entire expansion support pile 33 can be lifted by hanging it on the hook 34 using the lock of the lifting equipment, and then inserted into the enlarged opening at the upper end of the uppermost load-bearing column 1, and then enters the reduced opening of the load-bearing column 1, continues to slide down, and is inserted into the insertion end 22. The enlarged end is located on the upper end surface of the insertion end 22, and the enlarged end here acts as a counterweight.

[0050] In addition, the entire expansion pile 33 is axially provided with a casting hole, and concrete is poured into the expanded opening of the upper bearing column 1. The concrete will flow through the casting hole and continue to flow downward to fill the interior of the bearing column 1, so as to enhance the bearing strength of the entire bearing column 1.

[0051] In summary, a corresponding number of prefabricated bearing columns 1 are selected according to the depth requirements of the support system, two adjacent bearing columns 1 are connected via a docking pile 2, and then a reinforcement is inserted into the insertion end 22. The reinforcement is used to push multiple rotating and close-together flip blocks to rotate in the opposite direction, and the protrusion 21 is pushed out of the through hole one and inserted into the through hole two 11, so as to prevent the insertion end 22 from arbitrarily detaching from the enlarged opening at the end of the bearing column 1, and stably dock the docking pile 2 with the bearing column 1.

[0052] Embodiment 2, this embodiment discloses a mounting guide platform for mounting a bearing column, such as Figure 7 As shown, it includes an installation guide platform 4, which is a hollow rectangular frame. A positioning sleeve 5 is fixedly welded on the upper end of the installation guide platform 4, and a guide sleeve 7 is fixedly welded on the lower end of the installation guide platform 4. The positioning sleeve 5 and the guide sleeve 7 are coaxial and have the same inner diameter. The positioning sleeve 5 and the guide sleeve 7 are used to guide the sinking installation of the bearing column 1, and the inner space of the positioning sleeve 5 and the guide sleeve 7 is used for the bearing column 1 to pass through when sinking and installing.

[0053] It also includes a correction sleeve 6, which is located between the positioning sleeve 5 and the guide sleeve 7 and can be adjusted up and down; specifically, the radial side wall of the correction sleeve 6 is provided with at least two hollow sleeves 61, one of the hollow sleeves 61 is slidably sleeved with an insertion rod 65, and the axial ends of the insertion rod 65 are respectively fixedly connected to the bottom wall and the top wall of the inner side wall of the mounting guide platform 4; the other hollow sleeve 61 is threadedly inserted with a threaded transmission rod 62, and the axial ends of the threaded transmission rod 62 are respectively fixedly connected to the bottom wall and the top wall of the inner side wall of the mounting guide platform 4, and a motor is fixed to the bottom wall of one side of the mounting guide platform 4, and the output end of the motor rotates through the bottom side wall of the mounting guide sleeve 7 and is connected to a toothed disc 1 64, and the outer wall of the bottom end of the threaded transmission rod 62 is fixedly sleeved with a toothed disc 2 63, and the toothed disc 1 64 is meshed with the toothed disc 2 63. The motor provides rotational power for gear plate 1 64, gear plate 2 63 rotates synchronously with gear plate 1 64, and the threaded transmission rod 62 rotates synchronously, which can drive the hollow sleeve 61 on the side wall of the correction sleeve 6 to adjust up and down along the axial direction of the threaded transmission rod 62, and the other hollow sleeve 61 slides up and down synchronously along the outer wall of the insertion rod 65 to ensure that the height of the correction sleeve 6 is adjusted up and down in the vertical direction.

[0054] Here, the inner diameters of the correction sleeve 6, the positioning sleeve 5 and the guide sleeve 7 are the same, and are all larger than the diameter of the bearing column 1. As a result, when the bearing column 1 is sunk for installation, there is a gap between the correction sleeve 6, the positioning sleeve 5 and the inner walls of the guide sleeve 7, causing the bearing column 1 to be easily tilted.

[0055] To this end, the inner space of the correction sleeve 6 and the positioning sleeve 5 is provided with a positioning piece; specifically, as Figure 7 and Figure 8 As shown, the positioning member includes a plurality of arc-shaped clamping plates 81 and a threaded adjustment rod 8 rotatably connected to the outer wall of the arc-shaped clamping plates 81. The plurality of arc-shaped clamping plates 81 are distributed in an annular structure. Slots are provided at both ends of the arc-shaped clamping plates 81. A connecting spring 82 is slidably inserted between the slots of two adjacent arc-shaped clamping plates 81. Threaded holes threadedly connected to the threaded adjustment rod 8 are provided on the radial side walls of the correction sleeve 6 and the positioning sleeve 5. Each positioning member has at least three arc-shaped clamping plates 81. The three arc-shaped clamping plates 81 are distributed in an annular structure and can form a limiting structure that is stuck on the radial outer wall of the bearing column 1. Specifically, by rotating the threaded adjustment rod 8, the threaded adjustment rod 8 rotates along the axial direction of the corresponding threaded hole, which can drive the arc-shaped clamping plate 81 to adjust its position synchronously, so that the inner diameter of the annular structure can be adjusted, so as to be used for positioning and clamping bearing columns 1 with different outer diameters.

[0056] like Fig.10 As shown, a connecting spring piece 82 is slidably inserted between two adjacent arc-shaped clamping plates 81. Both ends of the connecting spring piece 82 are provided with extension parts, and the slot is provided with an extended recessed part that is slidably inserted with the extension part. In this way, the connecting spring piece 82 can be prevented from sliding out of the slot.

[0057] Further, such as Fig. 9 As shown, the multiple arc-shaped card plates 81 located in the positioning sleeve 5 are all embedded with vertically downward laser emitters 83, and the multiple arc-shaped card plates 81 located in the correction sleeve 6 are all embedded with vertically downward laser receivers 84. According to the outer diameter of the bearing column 1, the positions of the multiple arc-shaped card plates 81 in the correction sleeve 6 and the positioning sleeve 5 are adjusted respectively, so that the inner diameters of the annular structures formed by the arc-shaped card plates 81 in the correction sleeve 6 and the positioning sleeve 5 are equal. In this way, the laser emitter 83 and the laser receiver 84 are directly opposite to each other up and down, the laser emitter 83 emits laser, and the laser receiver 84 receives laser. The coordinated use of the laser emitter 83 and the laser receiver 84 is to realize laser positioning, ensuring that the arc-shaped card plates 81 in the correction sleeve 6 and the positioning sleeve 5 are directly opposite to each other up and down.

[0058] The specific method for correcting the verticality of the bearing column 1 is to hoist the installation guide platform 4 to the position of the pile groove slot, and adjust the position of the installation guide platform 4 so that the positioning sleeve 5, the correction sleeve 6 and the guide sleeve 7 are directly opposite to the pile groove slot, and then the bearing column 1 is passed through the inner space of the positioning sleeve 5, the correction sleeve 6 and the guide sleeve 7, and at the same time, the correction sleeve 6 is adjusted upward in height to approach the positioning sleeve 5, and according to the outer diameter of the bearing column 1, the inner diameter of the annular structure composed of the correction sleeve 6 and the arc-shaped clamping plate 81 in the positioning sleeve 5 is adjusted to be equal, and then the correction sleeve 6 is uniformly lowered in height from top to bottom. The arc-shaped clamping plate 81 in the correction sleeve 6 can push the inclined bearing column 1 to move in the horizontal direction during the process from top to bottom, so that the bearing column 1 is gradually corrected from the inclined state to the vertical state.

[0059] In summary, by installing the guide platform 4 for vertical installation, the verticality of the bearing column 1 is easy to control, and finally the vertical support system composed of multiple bearing columns 1 has strong support stability, and the bearing capacity can be guaranteed, thereby ensuring the quality and safety of the reverse engineering.
