Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a steel wedge slope adjusting device in a bent cap support system. Background Technique

[0002] During the erection process of the bent cap support system, in order to ensure that the bottom elevation of the bent cap meets the design requirements and to ensure that each component of the support system meets the requirements for post-construction removal, the auxiliary devices adopted in the traditional process are sand barrels, jacks, conventional steel wedge devices, etc. The traditional elevation fine-tuning device for the bent cap support system has poor mobility and can only ensure the function of fine-tuning the elevation of the support system (ensuring that the device elevation is lowered at the end of construction so that the components of the support system can be removed after being separated from the bottom surface of the bent cap), and it cannot achieve cross-slope matching.

[0003] Among them, the sand barrel device is only limited to the first elevation calibration and cannot efficiently meet the secondary calibration requirements after elevation verification; when the elevation of the jack device is lowered, it cannot meet the fine-tuning requirements and there is a hidden danger of rapid lowering. The connection surface between the top of the elevation fine-tuning device and the main girder I-beam of the support system cannot be fitted, and the cross-slope calibration of the device top plate cannot be achieved, resulting in a phenomenon of voids in the contact area. It only bears force in line contact, leading to potential risks of eccentric compression of the device and concentrated force on the upper I-beam main girder, increasing the shear stress between components.

[0004] Therefore, the utility model provides a steel wedge slope adjusting device in a bent cap support system. A steel wedge device for fine-tuning elevation and cross-slope is arranged in the support system of the structure. By screwing the screw rod in the device and squeezing and loosening the wedge blocks, the up-and-down calibration of the device elevation is realized.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0024] The present application will be further elaborated in detail below with reference to the drawings and embodiments.

[0025] Refer to Figures 1 to 6 , the embodiments of the present application provide a steel wedge slope adjustment device in a capping beam support system, including a lower wedge block 1 and an upper wedge block 2. Both the lower wedge block 1 and the upper wedge block 2 are right-angled trapezoidal blocks. The inclined surface of the upper wedge block 2 is mutually attached to the inclined surface of the lower wedge block 1. A first notch 3 is opened on the left side of the upper wedge block 2, a second notch 10 is opened on the right side of the lower wedge block 1, a fourth notch 13 is opened at the lower right of the upper wedge block 2, and a third notch 12 is opened at the upper left of the lower wedge block 1. A screw 4 is inserted between the first notch 3, the second notch 10, the third notch 12, and the fourth notch 13. Two nuts 5 are screwed on the outer side of the screw 4, and the two nuts 5 are respectively located on the left side of the upper wedge block 2 and the right side of the lower wedge block 1. A wedge block support plate 11 is fixedly installed at the higher position on the right side of the lower wedge block 1, and the wedge block support plate 11 is located on the right side of the right side surface of the upper wedge block 2.

[0026] Two perforated special-shaped plates 7 are fixedly installed at the top of the upper wedge block 2. A cross-slope fine-tuning cover 6 is hinged to the top right of the upper wedge block 2, and the cross-slope fine-tuning cover 6 is located above the perforated special-shaped plate 7.

[0027] A bolt 9 is screwed inside the perforated special-shaped plate 7. An inner clamping plate 14 is fixedly installed at the bottom of the cross-slope fine-tuning cover 6, and the height of the bolt 9 increases sequentially from left to right.

[0028] A sand filling port 15 is opened in the upper left of the cross-slope fine-tuning cover 6, and a sleeve cover 8 is hinged inside the sand filling port 15. Both the lower wedge block 1 and the upper wedge block 2 are of hollow structure, and auxiliary support plates are fixedly installed inside both the lower wedge block 1 and the upper wedge block 2. The auxiliary support plate inside the lower wedge block 1 is parallel to the front and rear surfaces of the lower wedge block 1 and has the same shape, and the auxiliary support plate inside the upper wedge block 2 is parallel to the front and rear surfaces of the upper wedge block 2 and has the same shape.

[0029] The lower wedge block 1 of the steel wedge device is composed of an inclined panel, a bottom plate, side plates, internal reinforcing rib plates of the wedge block, and wedge block cushioning parts. Among them, the plate thickness of the wedge block cushioning part is selected as a steel plate with a thickness of 1.5 cm, and the thickness of other plate parts is selected as a steel plate with a thickness of 1 cm. All plate parts are connected and formed by welding. A notch is opened in the middle of the inclined panel of the steel wedge, the width of the notch is 30 mm, a notch is arranged in the middle of the high-side side plate of the steel wedge correspondingly, the groove width is also set to 30 mm, and the groove length is set to 7 cm.

[0030] Special setting: The trapezoidal side panels on both sides of the lower wedge block are embedded 1.5 cm inward compared with the rectangular side panels, so that the fingers of construction workers can grasp the edge eaves at this place during handling; at the same time, a wedge block cushioning part is welded to the top of the long-side rectangular side panel. Mainly to meet the requirement that when the steel wedge device is loosened, its upper support system can be located on both the upper wedge block and the cushioning part at the same time, avoiding the situation that the support system only sits on the upper wedge block and overturns due to eccentric compression during the disassembly process. The size of the cushioning part is set to 8 cm * 35 cm, and the top protrudes 3.3 cm higher than the inclined surface top edge of the lower wedge block.

[0031] The upper wedge block of the steel wedge device is composed of an inclined panel, a top plate, triangular side plates, rectangular side plates, perforated special-shaped side plates, internal reinforcing rib plates of the wedge block, and bearing sleeves. The thickness of each plate part is selected as a steel plate with a thickness of 1 cm. The outer diameter of the bearing sleeve is 1 cm, and the wall thickness is 1 mm. All plate parts are connected and formed by welding. Notches are opened in the middle of both the inclined panel and the high-side rectangular side plate of the steel wedge, and the notch size and position are the same as those of the lower wedge block.

[0032] Special setting:

[0033] The triangular side panels on both sides of the wedge block are embedded 1.5 cm inward compared with the rectangular side panels, so that the fingers of construction workers can grasp the edge eaves at this place during handling.

[0034] Compared with the lower wedge block, its top panel is set in the middle of the wedge block, leaving a vacant area reserved at the top of the wedge block to ensure that the cross-slope fine-tuning component can be freely embedded into the pothole.

[0035] On both sides of the edge of the top plate of the wedge block, a special-shaped side plate with holes is provided. The diameter of each hole is set to 8 mm, and the inside of the hole is a threaded structure for installing bolts during the construction process. At the same time, the cross-slope value is engraved at the corresponding position of each hole to ensure accurate search during construction. (To meet various cross-slope parameters as much as possible and reduce the number of holes, the following cross-slope parameter values are set. Just select the hole close to the design parameter value during construction.)

[0036] When setting any cross-slope value, if the reserved holes are not closed tightly, bolt 9 is used to tighten and block them. (When selecting a certain cross-slope value, the corresponding bolt hole is tightened with a long bolt, and the long bolt cap is marked with a special horizontal notch. The other holes are tightened and blocked with short bolts. During the process, no bolt can be missing from each hole. To avoid bolt loss, the positions of the short and long bolts are swapped to organize the construction to ensure that each bolt is on the special-shaped side plate.)

[0037] To facilitate the rotation of the cross-slope fine-tuning component at the top of the upper wedge block and have a connection relationship with the upper wedge block, a bearing sleeve is specially set on the top of the lower rectangular side plate of the upper wedge block. (The sleeve is welded to the side plate of the wedge block as a whole, distributed on both sides of the side plate, and the welding length on each side is 10 cm, with a 15 cm gap reserved in the middle for the rotation shaft of the cross-slope fine-tuning component to pass through.) The outer diameter of the sleeve is 1 cm, the inner diameter is 8 mm, and the wall thickness is 1 mm.

[0038] To make the cross-slope fine-tuning component rotate around the top of the upper wedge block, a rotating shaft is welded at the bottom of the rear side plate of the device. The diameter of the middle rotating shaft is 1 cm and the length is 15 cm. The diameters of the two ends of the rotating shaft are 8 mm and the lengths are both 10 cm. The middle and the two ends of the rotating shaft are welded into a whole and passed through the bearing sleeve on the top of the lower side plate of the upper wedge block.

[0039] To ensure that there is no interference between the cross-slope fine-tuning component and the upper wedge block during the rotation adjustment process and avoid gaps between the cross-slope fine-tuning component and the wedge block during use, the size of the inner clamping plate is specially treated. The end of the clamping plate is set into a double chamfer structure to further ensure the normal use of the device.

[0040] Since the cross-slope fine-tuning device selects different cross-slope parameter values, the internal space changes constantly, making it impossible to set the internal stiffening rib plate in a fixed form. Therefore, its interior is set as a hollow structure. After the cross-slope adjustment of the device is completed, fine sand is poured into its interior through the holes reserved on the top panel to fill the entire internal space, further enhancing the bearing capacity of this part of the device. To ensure that there is no overflow from the sand filling holes and to ensure that the cover plates are not lost during the construction process, the cover plates and the top panel are welded into a whole by means of bearing rotation. The rotation shaft principle and dimension construction are the same as those of the above-mentioned bearing sleeve and rotation shaft. At the same time, to ensure that the cover plates are tightly buckled and there is no interference or jamming with the top panel, the edges of the cover plates are set as inclined surfaces.

[0041] The tensioning high-strength steel bar assembly is mainly used to finely adjust the elevation according to the fine-tuning requirements of the elevation of the bent cap support system by loosening or tightening the nuts on both sides of the tie rod, further realizing the fine adjustment of the elevation and ensuring that the bottom elevation of the bent cap structure meets the design and specification requirements. During the process, the high-strength steel bar tie rods are installed in a horizontal state, so that the tie rods are always under tension when the steel wedges are under pressure, and the design force is safer and more reliable than that of the traditional steel wedge device (the side plates of the traditional steel wedge are provided with holes, and the high-strength steel bar tie rods installed are inclined during the elevation adjustment process, so that when the steel wedges are under pressure, the tie rods are subjected to single-point shear force at the holes of the side plates). The assembly is mainly equipped with high-strength steel bars with a diameter of φ28mm and double nuts.
