Description

Technical Field

[0001] The present application relates to the field of pylon construction, and particularly to a method for adjusting the accuracy of the steel section combination section of the pylon steel bars. Background Art

[0002] The pylon of a suspension bridge is a tower structure for supporting the main cable. Common pylon forms are arranged longitudinally along the bridge with single-column, A-shaped, and inverted Y-shaped, and arranged transversely along the bridge with single-column, double-column, portal, inclined-leg portal, inverted V-shaped, inverted Y-shaped, A-shaped, etc. The cross-section of the pylon can adopt a solid interface according to the design requirements.

[0003] The tower columns of the suspension bridge pylon generally adopt climbing formwork construction. Before pouring each layer of concrete, it is necessary to extend the exposed steel bars at the top of the previous layer of concrete. The steel bar connector generally uses a threaded sleeve, which has the advantage of low price, but has high requirements for the alignment accuracy of the steel bars. In related technologies, to improve the overall installation efficiency of the steel bars, frame-type steel members such as steel bar components are used to position multiple steel bars, and then the whole is hoisted by a tower crane, and then the steel bars of adjacent upper and lower steel bar components are connected. When constructing to the middle section of the tower body, it is necessary to add a cross brace between the two tower columns of the pylon. The connection part between the tower column and the cross brace is the combination section of the tower column. The steel bar components at the tower column combination section need to have strong structural strength. Therefore, it is necessary to add a steel skeleton to the steel bar components at the combination section position. During the hoisting process, since the steel bar components need to support the overall weight of the steel bars and the steel skeleton, the steel bar components will be deformed, resulting in a deviation in the alignment of the steel skeletons of adjacent upper and lower steel bar components, reducing the construction efficiency. Therefore, there is still room for improvement. Summary of the Invention

[0004] In order to facilitate the docking of the steel skeletons of adjacent upper and lower steel bar components, the present application provides a method for adjusting the accuracy of the steel section combination section of the pylon steel bars.

[0005] The method for adjusting the accuracy of the steel section combination section of the pylon steel bars provided by the present application adopts the following technical solution:

[0006] A method for adjusting the accuracy of the steel section combination section of the pylon steel bars includes the following steps:

[0007] S1: Construction preparation: Precast steel bar components. The steel bar components at the tower column combination section are sequentially divided into lower steel bar components, middle steel bar components, and upper steel bar components from bottom to top. The upper end of the steel skeleton in the lower steel bar component protrudes, the upper and lower ends of the steel skeleton in the middle steel bar component protrude, the lower end of the steel skeleton in the upper steel bar component protrudes. The steel skeleton of the middle steel bar component is rotatably connected to the middle steel bar component, the steel skeleton of the upper steel bar component is rotatably connected within the upper steel bar component, and the rotation axis of the steel skeleton is perpendicular to the steel skeleton.

[0008] S2: Hoist the lower steel bar component: Hoist the lower steel bar component to the lower position of the column joint section for installation and fixation, and then pour the lower part of the column joint section;

[0009] S3: Hoist the middle steel bar component: Hoist the middle steel bar component directly above the lower steel bar component, and then slowly lower the middle steel bar component. Swing and adjust the steel skeleton of the middle steel bar component, align and connect the steel skeletons of the lower steel bar component and the middle steel bar component, and then pour the middle part of the column joint section;

[0010] S4: Hoist the upper steel bar component: Hoist the upper steel bar component directly above the middle steel bar component, and then slowly lower the upper steel bar component. Swing and adjust the steel skeleton of the upper steel bar component, align and connect the steel skeletons of the upper steel bar component and the middle steel bar component, and then pour the upper part of the column joint section.

[0011] By adopting the above technical solution, the steel skeleton of the lower steel bar component protrudes from the upper surface of the lower steel bar component, the steel skeleton of the middle steel bar component penetrates through the middle steel bar component, and the steel skeleton of the upper steel bar component protrudes from the lower surface of the upper steel bar component, providing an operating space for the butt-joint position of the steel skeletons between the lower steel bar component and the middle steel bar component and between the middle steel bar component and the upper steel bar component. Moreover, the angular adjustment of the steel skeletons of the upper steel bar component and the middle steel bar component is realized by means of a rotational connection, so as to facilitate the adjustment and butt-joint between the steel skeletons of the adjacent upper and lower steel bar components. In addition, after the installation of the lower steel bar component is completed, the pouring construction of the lower position of the column joint section is carried out to form a construction platform, which is convenient for the construction personnel to carry out the steel bar connection operation and the steel skeleton butt-joint operation between the steel bar components, and is beneficial to improving the construction efficiency of the bridge tower.

[0012] Preferably, the steel skeleton is an I-shaped steel, the rotating shaft of the steel skeleton is fixed outside the two flange plates of the steel skeleton, and the rotating shaft of the steel skeleton and the web of the steel skeleton are in the same plane.

[0013] By adopting the above technical solution, the I-shaped steel is used as the steel skeleton of the steel bar component, the rotating shaft of the steel skeleton is arranged outside the flange plate of the steel skeleton, and the rotating shaft of the steel skeleton and the web of the steel skeleton are in the same plane, so as to achieve the purpose of stable swing of the steel skeleton.

[0014] Preferably, two clamping plates are arranged between the connecting ends of two adjacent steel skeleton members up and down. The two clamping plates are respectively located outside the two flange plates of the steel skeleton member. A locking member is arranged between the two clamping plates. The locking member is used to drive the adjacent clamping plates to approach each other and lock the connecting ends of two adjacent steel skeleton members up and down. When the inner sides of the two clamping plates are completely attached to the outer sides of the flange plates of the steel skeleton member, the connecting ends of two adjacent steel skeleton members up and down are aligned with each other.

[0015] Since the rotating shaft of the steel skeleton member and the web are in the same plane, the method of swinging the steel skeleton member can only adjust the webs of two adjacent steel skeleton members up and down to be in the same plane, but cannot adjust the relative positions of the flange plates of two adjacent steel skeleton members up and down. By adopting the above technical solution, the locking member is used to force the two clamping plates to approach each other, and the pressing plate moves towards the flange plate. Under the clamping action of the two clamping plates, the flange plates of two adjacent steel skeleton members up and down are tightly attached to the inner sides of the clamping plates and maintain the same verticality. When the inner sides of the clamping plates are completely attached to the outer sides of the flange plates of the steel skeleton member, the connecting ends of two adjacent steel skeleton members up and down are aligned with each other, achieving the purpose of fine adjustment of the steel skeleton member and being beneficial to the alignment of the steel skeleton member.

[0016] Preferably, a screw rod is arranged at the connecting end of the steel skeleton member. The screw rod vertically penetrates through the two flange plates of the steel skeleton member. A through groove for the screw rod to pass through is formed in the clamping plate along the thickness direction of the clamping plate. The locking member includes a nut and a lock washer. The nut is threadedly connected to the end of the screw rod, and the lock washer is sleeved on the end of the screw rod. The lock washer is clamped between the nut and the clamping plate.

[0017] By adopting the above technical solution, the screw rod plays a positioning role for the clamping plate, and through the threaded cooperation between the nut and the screw rod, the threaded locking of the clamping plate is realized. The lock washer plays an anti-loosening effect, which is beneficial to improving the stability of the clamping plate.

[0018] Preferably, the length direction of the through groove is consistent with the length direction of the steel skeleton member; a tie bolt is arranged between the connecting ends of two adjacent steel skeleton members up and down. The tie bolt is used to lock the screw rods between two adjacent steel skeleton members.

[0019] By adopting the above technical solution, under the locking action of the tie bolt, the connecting ends of two adjacent steel skeleton members up and down are driven to approach each other until they are in contact with each other, so as to facilitate the construction personnel to weld the connection part between the steel skeleton members.

[0020] Preferably, the lower steel bar component and the middle steel bar component are fixedly hooked by a tie bar, and the middle steel bar component and the upper steel bar component are fixedly hooked by a tie bar.

[0021] By adopting the above technical solution, since there is a rotational relationship between the middle steel bar component and the steel section frame, as well as between the upper steel bar component and the steel section frame, the stability of the middle steel bar component and the upper steel bar component is insufficient. Hooking and fixing the upper and lower steel bar components through tie bars is beneficial to improving the position accuracy of each steel bar component in the tower column joint section.

[0022] Preferably, before hoisting the lower steel bar component, several vertically arranged support steel members are pre-embedded on the top surface of the already constructed section of the tower column. The several support steel members are distributed on the periphery of the installation position of the lower steel bar component. A horizontal jack is installed on the side of the support steel member facing the lower steel bar component. When hoisting the lower steel bar component, the several horizontal jacks perform jacking and adjusting on the corner positions of the lower steel bar component.

[0023] By adopting the above technical solution, using the support steel member as a support point and performing jacking and adjusting through the horizontal jack to achieve the rough adjustment purpose of the lower steel bar component is beneficial to improving the position accuracy of the installation of the steel bar component.

[0024] Preferably, before hoisting the middle steel bar component, the support steel member is extended upward, and the horizontal jacks are installed on the periphery of the installation position of the middle steel bar component. When hoisting the middle steel bar component, the several horizontal jacks perform jacking and adjusting on the corner positions of the middle steel bar component.

[0025] By adopting the above technical solution, to achieve the rough adjustment purpose of the middle steel bar component is convenient for aligning the steel section frames of the lower steel bar component and the middle steel bar component.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By protruding the steel section frame of the lower steel bar component above the upper surface of the lower steel bar component, passing the steel section frame of the middle steel bar component through the middle steel bar component, and protruding the steel section frame of the upper steel bar component below the lower surface of the upper steel bar component, an operating space is provided for the docking position of the steel section frames between the lower steel bar component and the middle steel bar component, as well as between the middle steel bar component and the upper steel bar component. Moreover, the angle adjustment of the steel section frames of the upper steel bar component and the middle steel bar component is realized by adopting a rotational connection method, thus facilitating the adjustment and docking between the steel section frames of the adjacent upper and lower steel bar components;

[0028] 2. Using the locking member to force the two clamping plates to approach each other, the pressing plate moves towards the flange plate direction. Under the clamping action of the two clamping plates, the flange plates of the two adjacent upper and lower steel section frames closely fit with the inner sides of the clamping plates and maintain the same verticality. When the inner sides of the clamping plates are completely in contact with the outer sides of the flange plates of the steel section frames, the connecting ends of the two adjacent upper and lower steel section frames are aligned with each other, achieving the fine adjustment purpose of the steel section frame and being beneficial to the alignment of the steel section frame;

[0029] 3. Use the supporting steel members as the supporting points and adjust the jacking through the horizontal jacks to achieve the rough adjustment of the lower steel bar components, which is beneficial to improving the position accuracy of the installation of the steel bar components.

Detailed Description of the Embodiment

[0035] The following will further describe the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0036] An embodiment of the present application discloses a method for adjusting the accuracy of the steel section joint of the tower column steel bar components. Among them, referring to Figure 1 , the tower column joint section 3 is the section at the connection between the tower column and the cross brace 1.

[0037] Referring to Figures 2 to 4 , it includes the following steps:

[0038] S1: Construction preparation: Prefabricate steel bar components. The steel bar components at the three tower column joint sections are successively divided into lower steel bar components 4, middle steel bar components 6, and upper steel bar components 7 from bottom to top. The upper end of the steel skeleton 5 in the lower steel bar component 4 protrudes. The upper and lower ends of the steel skeleton 5 in the middle steel bar component 6 protrude. The lower end of the steel skeleton 5 in the upper steel bar component 7 protrudes. Among them, the steel skeleton 5 of the middle steel bar component 6 is rotatably connected to the middle steel bar component 6, and the steel skeleton 5 of the upper steel bar component 7 is rotatably connected within the upper steel bar component 7. The axis of rotation of the steel bar skeleton is perpendicular to the length direction of the steel bar skeleton.

[0039] S2: Hoist the lower steel bar component 4: First, embed several vertically arranged support steel members 21 in the already constructed section 2 of the tower column. The several support steel members 21 are distributed on the periphery of the installation position of the lower steel bar component 4. A horizontal jack 22 is installed on the side of the support steel member 21 facing the installation position of the lower steel bar component 4. A push plate 23 is fixed to the telescopic end of the horizontal jack 22. When hoisting the lower steel bar component 4, several horizontal jacks 22 perform horizontal jacking adjustment on the corner positions of the lower steel bar component 4 to achieve the purpose of rough adjustment of the lower steel bar component 4, which is beneficial to improving the position accuracy of the installation of the steel bar component. Then hoist the lower steel bar component 4 above the already constructed section 2 of the tower column. After the lower steel bar component 4 is in place at the installation position, connect the steel bars of the lower steel bar component 4 to the steel bars exposed at the top of the already constructed section 2 of the tower column, thereby fixing the lower steel bar component 4 at the lower position of the tower column joint section 3. Move the horizontal jack 22 upward to the top of the support steel member 21. Erect a formwork around the lower steel bar component 4. The height position of the formwork is lower than that of the horizontal jack 22. Then pour the lower part of the tower column joint section 3. The top of the lower steel bar component 4 is exposed on the lower surface of the tower column joint section 3, providing a connection space for the installation of the tie bar 24 in the subsequent steps. The horizontal jack is not embedded in the lower part of the tower column joint section, preparing for the installation of the middle steel bar component in the subsequent steps.

[0040] S3: Hoist the middle steel bar component 6: Extend the support steel member 21 upward, and then move the horizontal jack 22 upward to install the horizontal jack 22 on the periphery of the installation position of the middle steel bar component 6. Hoist the middle steel bar component 6 directly above the lower steel bar component 4, and then slowly lower the middle steel bar component 6. When hoisting the middle steel bar component 6, several horizontal jacks 22 perform jacking adjustment on the corner positions of the middle steel bar component 6 to achieve the purpose of rough adjustment of the position of the middle steel bar component 6, facilitating the alignment of the steel skeletons 5 of the lower steel bar component 4 and the middle steel bar component 6.

[0041] Then swing and adjust the steel skeleton 5 of the middle steel bar component 6, align and connect the steel skeletons 5 of the lower steel bar component 4 and the middle steel bar component 6, and then use the tie bars 24 to hook and fix the lower steel bar component 4 and the middle steel bar component 6 to stabilize the middle steel bar component 6, and then pour the middle part of the tower column joint section 3.

[0042] Refer to Figure 3 and Figure 4 In this embodiment, the steel skeleton 5 is an I-shaped steel. The rotating shaft of the steel skeleton 5 is fixed on the outer sides of the two flange plates 52 of the steel skeleton 5, and the rotating shaft of the steel skeleton 5 and the web 51 of the steel skeleton 5 are in the same plane. The rotating shaft of the steel skeleton 5 is horizontally arranged. By swinging the steel skeleton 5, the webs 51 of the upper and lower adjacent steel skeletons 5 can be swung to the same horizontal plane.

[0043] In addition, two clamping plates 55 are arranged between the connecting ends of the upper and lower adjacent steel skeletons 5. The two clamping plates 55 are respectively located on the outer sides of the two flange plates 52 of the steel skeleton 5. A locking member is installed between the two clamping plates 55. The locking member is used to drive the adjacent clamping plates 55 to approach each other and lock the connecting ends of the upper and lower adjacent steel skeletons 5.

[0044] Specifically, a screw rod 53 is fixed to the connecting end of the steel skeleton 5. Among them, the screw rod 53 vertically penetrates through the two flange plates 52 of the steel skeleton 5. The number of screw rods 53 at the connecting end of the steel skeleton 5 is 2, and the two screw rods 53 are respectively arranged on both sides of the web 51 of the steel skeleton 5.

[0045] The clamping plate 55 is provided with a through groove for the screw rod 53 to pass through along its own thickness direction, and the length of the through groove is the same as the length of the steel skeleton 5.

[0046] Among them, the locking member includes a nut 54 and a lock washer. The nut 54 is threadedly connected to the end of the screw rod 53, and the lock washer is sleeved on the end of the screw rod 53. The lock washer is clamped between the nut 54 and the clamping plate 55. By screwing the nut 54 in the direction towards the clamping plate 55, the connecting ends of the upper and lower adjacent steel skeletons 5 are clamped between the two clamping plates 55. And when the inner sides of the two clamping plates 55 are completely attached to the outer sides of the flange plates 52 of the steel skeleton 5, the connecting ends of the upper and lower adjacent steel skeletons 5 are aligned with each other. The screw rod 53 plays a positioning role for the clamping plate 55, and through the threaded cooperation between the nut 54 and the screw rod 53, the threaded locking of the clamping plate 55 is realized. The lock washer plays an anti-loosening effect, which is beneficial to improving the stability of the clamping plate 55.

[0047] In order to facilitate the butt joint of the upper and lower adjacent profiled steel skeletons 5, a tension bolt 8 is arranged between the connecting ends of the upper and lower adjacent profiled steel skeletons 5. The tension bolt 8 is used to lock the screw rod 53 between the upper and lower adjacent profiled steel skeletons 5. Among them, the tension bolt 8 includes a threaded rod member 81, two pressing plates 83 and two bolt heads 82. The length direction of the threaded rod member 81 of the tension bolt 8 is consistent with the length direction of the profiled steel skeleton 5, and the threaded rod member 81 is located between the two screw rods 53. The two pressing plates 83 are distributed up and down. By screwing the two bolt heads 82 along the length direction of the threaded rod member 81 towards the direction of each other's space, the two pressing plates 83 are forced to press the screw rod 53, thereby driving the butt joint of the connecting ends of the upper and lower adjacent profiled steel skeletons 5 to facilitate the welding operation of the construction workers.

[0048] S4: Hoist the upper steel bar component 7: Extend the supporting steel member 21 upwards, and then move the horizontal jack 22 upwards to install the horizontal jack 22 on the periphery of the installation position of the upper steel bar component 7. Hoist the upper steel bar component 7 to directly above the middle steel bar component 6, and then slowly lower the upper steel bar component 7. When hoisting and placing the upper steel bar component 7, several horizontal jacks 22 perform jacking adjustment on the corner positions of the upper steel bar component 7 to achieve the purpose of rough adjustment of the position of the upper steel bar component 7, facilitating the alignment of the profiled steel skeletons 5 of the upper steel bar component 7 and the middle steel bar component 6. Then use the tie bars 24 to hook and fix the upper steel bar component 7 and the middle steel bar component 6, and finally pour the upper part of the tower column joint section 3. Among them, the butt joint method of the profiled steel skeletons 5 of the upper steel bar component 7 and the middle steel bar component 6 is the same as that of the profiled steel skeletons 5 of the lower steel bar component 4 and the middle steel bar component 6, and it is also carried out by the method of locking with the screw rod 53 and the pressing plate 83 and the method of tension locking with the tension bolt 8.

[0049] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
