Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, specifically to a universal sliding support for the construction of segmental beams in the pier top area. Background Technology

[0002] With the gradual development of bridge construction and looking towards future technologies, future bridge piers and abutments will shed their bulky and cumbersome appearance, fully demonstrating "small size, big energy" to achieve greater spans. However, this "small size, big energy" structural form often concentrates weight more, which brings difficulties to scaffolding construction. In particular, the 0# block segment of a continuous beam (also known as the pier top area segmental beam) requires scaffolding to support the casting formwork during pouring, but the very small support surface of the 0# block segment of a continuous beam makes it difficult to perform support pouring.

[0003] Among the relevant technologies, the traditional and widely used technical solutions to solve the above problems are the pre-embedded bracket support scheme and the pipe pile ground support scheme.

[0004] However, when the transverse width of the pier is narrow, the embedded corbel support scheme cannot be aligned with the web of the beam to provide effective support for the cast-in-place construction of the segmental beam. When the pile cap is circular or has a small planar size, the pipe pile ground support scheme cannot provide sufficient support surface, with some support on the pile cap and some on the ground. The ground support will result in uneven settlement due to the different strength of the bottom support. Both technical schemes also have problems such as a large amount of high-altitude welding work during construction, high construction safety risks, low efficiency of support erection and dismantling, strong structural specificity, and difficulty in recycling. Summary of the Invention

[0005] This application provides a universal sliding support for the construction of segmental beams in the pier top area, which solves the problems of insufficient support surface and uneven settlement, and makes construction safe, efficient and convenient.

[0006] This application provides a general-purpose sliding support for the construction of segmental beams in the pier top area, comprising: several embedded parts, which are set on the top surface of the pier cap and avoid the web of the beam, and the several embedded parts are arranged in multiple rows along the longitudinal direction, with no less than three in each row in the transverse direction;

[0007] Several pad beams, each pad beam is fixed to a row of the aforementioned embedded parts, and both ends of each pad beam extend beyond the side of the foundation.

[0008] The support frame assembly supports the bottom formwork assembly of the segmental beam in the pier top area to be poured at its top, and its bottom is fixed to several pad beams when supported, and its bottom can slide relative to several pad beams as a whole when disassembled.

[0009] Based on the above technical solution, the pad beam includes a slide rail, and the bottom of the support frame assembly is provided with several column feet, which are engaged in the slide rail;

[0010] The column base is fixed to the slide rail by bolts at the support point; when the column base is not at the support point, the bolts are removed and the column base is slidably disposed on the slide rail.

[0011] Based on the above technical solution, the overall sliding universal support also includes longitudinal beams and transverse distribution beams. Several longitudinal beams are set on the top of the support frame assembly, and several transverse distribution beams are perpendicularly intersected by several longitudinal beams. The bottom formwork assembly is supported on the top surface of the transverse distribution beams, and the longitudinal beams extend beyond the bottom surface of the segment beam in the pier top area to be poured on all four sides.

[0012] Based on the above technical solution, the overall sliding universal support also includes steel wedges, and a number of the steel wedges are set between the transverse distribution beam and the longitudinal beam to form an inclination that matches the bottom surface of the segment beam in the pier top area to be poured.

[0013] Based on the above technical solution, the overall sliding universal support also includes a safety guardrail, which is set on the edge of the longitudinal beam and is set vertically upward.

[0014] Based on the above technical solution, the bottom of the safety guardrail is hinged to the edge of the longitudinal beam and can be rotated relative to the longitudinal beam.

[0015] Based on the above technical solution, the support frame assembly includes an adjusting section steel pipe pile and a standard assembly section of the support frame. The standard assembly section of the support frame is processed according to a set height, and the adjusting section steel pipe pile is processed according to the height of the web of the beam.

[0016] Based on the above technical solution, the support frame assembly also includes a connecting system, which is fixedly disposed between the standard assembly sections of the support frame.

[0017] Based on the above technical solution, the standard assembly section of the support includes a standard section steel pipe pile, a flange, an inter-section connection system, and a pile cap. The flange is located at the bottom end of the standard section steel pipe pile, the pile cap is located at the top end of the standard section steel pipe pile, and the inter-section connection system is located between two adjacent standard section steel pipe piles.

[0018] Based on the above technical solution, after the segmental beam in the pier top area is poured, the pad beam is extended laterally, and the overall sliding universal support slides as a whole.

[0019] The beneficial effects of the technical solutions provided in this application include at least the following:

[0020] 1. The universal sliding support of this application forms a stable support foundation by setting several embedded parts on the top surface of the pier, avoiding the web of the beam. These embedded parts are arranged in multiple rows along the longitudinal direction. Then, a pad beam is fixed on each row of embedded parts. Both ends of each pad beam extend beyond the side of the pier, forming a support plane that is much larger than the pier. This solves the problem of insufficient support surface in traditional technical solutions. At the same time, it forms a support platform composed entirely of pad beams. Compared with the traditional technical solution where some parts are supported on the pier and some parts are supported on the ground, this solves the problem of uneven settlement caused by different underlying structures of the support points.

[0021] More importantly, the bottom of the support frame assembly can be detachably fixed to several pad beams. When the connection is fixed, it can form a stable support. When the connection is disassembled, that is, after the bottom fixed part of the support frame assembly is disassembled, it can slide relative to several pad beams as a whole. It can be efficiently disassembled as a whole and reused repeatedly, reducing the risk factor of high-altitude operations, improving construction efficiency, and meeting the current needs of most projects for bridge construction safety, efficiency and convenience.

[0022] 2. The universal sliding support of this application includes a pad beam containing a slide rail and column feet at the bottom of the support frame assembly. When stable support is required, the support points can be connected by bolts to form a stable support structure. At non-support points, the bolts can be removed, and the column feet can slide along the slide rail, allowing the universal sliding support to be withdrawn as a whole. While forming a stable support structure, it can also be withdrawn efficiently as a whole, greatly improving construction efficiency.

[0023] 3. The overall sliding universal support of this application has steel wedges set between the transverse distribution beam and the longitudinal beam. It can not only make fine height adjustments through the top steel wedges, but also meet the inclination requirements of the bottom surface of the segment beam in various pier top areas. By adjusting the height of the top surface of the support through the steel wedges, it can better adapt to the inclination angle requirements of the bottom of the beam than ordinary supports.

[0024] 4. The universal sliding support system of this application adopts a rotating safety railing. During formwork construction, it flips upwards for fixation; during removal, it flips downwards to avoid obstruction. This solves the problem that the support system cannot be completely removed from one side due to railing height limitations, reducing the amount of disassembly and assembly work.

[0025] 5. The overall sliding universal support of this application, which uses the adjustable section steel pipe pile and the standard assembly section of the support together, can quickly form the required support frame assembly. The prefabricated installation effectively reduces the amount of high-altitude work. In use, the support assembly is formed first and then hoisted. The prefabricated processing and hoisting of the support reduces the work of high-altitude assembly and welding, improves work efficiency, and reduces construction safety risks.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0034] This application provides a universal sliding support for the construction of segmental beams in the pier top area, which solves the problems of insufficient support surface and uneven settlement, and makes construction safe, efficient and convenient.

[0035] like Figures 1-5 As shown, this application discloses an embodiment of an integral sliding universal support for the construction of segmental beams in the pier top area. This integral sliding universal support is mainly used to support the formwork of the segmental beams in the pier top area during construction, so as to successfully complete the casting and shaping.

[0036] The overall sliding universal support includes a support frame assembly, several embedded parts 3, and several pad beams 4. The embedded parts 3 are located on the top surface of the foundation 1, and are positioned away from the web of the beam (see...). Figure 3 Specifically, the top surface of the foundation 1 is larger than the web of the beam, and several embedded parts 3 are set in the extra plane. If the embedded parts 3 are arranged in multiple rows along the longitudinal direction, the number of each row in the transverse direction shall not be less than three, so as to lay a good foundation for the subsequent support fixing.

[0037] Specifically, such as Figure 3 In the middle, several embedded parts 3 form four rows, with two rows on each side of the web of the beam. The bottom of each pad beam 4 is fixed with at least three embedded parts 3 to form a stable foundation.

[0038] Specifically, the distance from the outermost edge of the embedded part 3 on the top surface of the pier cap 1 to the edge of the pier cap shall not be less than 30cm to ensure stable support.

[0039] In a plurality of pad beams 4, each pad beam 4 is fixed to a row of embedded parts 3, and both ends of each pad beam 4 extend beyond the side of the foundation 1 to expand the support surface, thereby solving the problem of insufficient support surface in traditional technical solutions.

[0040] The top of the support frame assembly supports the bottom formwork assembly 12 of the segment beam 2 in the pier top area to be poured. The bottom of the support frame assembly can be detachably fixed to several pad beams 4, and the bottom fixing point of the support frame assembly can slide relative to the several pad beams 4 as a whole after disassembly.

[0041] The overall sliding universal support of this application is formed by setting several embedded parts 3 on the top surface of the pier 1, avoiding the web of the beam. The embedded parts 3 are arranged in multiple rows along the longitudinal direction to form a stable support foundation. Then, a pad beam 4 is fixed on each row of embedded parts 3. Both ends of each pad beam 4 extend beyond the side of the pier 1 to form a support plane that is much larger than the pier. This solves the problem of insufficient support surface in traditional technical solutions. At the same time, it forms a support platform composed entirely of pad beams 4. Compared with the technical solution in traditional solutions where some parts are supported on the pier and some parts are supported on the ground, it solves the problem of uneven settlement caused by different underlying structures of the support points.

[0042] More importantly, the bottom of the support frame assembly can be detachably fixed to several pad beams 4. When the connection is fixed, it can form a stable support. When the connection is disassembled, that is, after the bottom fixed part of the support frame assembly is disassembled, it can slide relative to several pad beams 4 as a whole. It can be efficiently disassembled as a whole and reused repeatedly, reducing the risk factor of high-altitude operations, improving construction efficiency, and meeting the current needs of most projects for bridge construction safety, efficiency and convenience.

[0043] Furthermore, in one embodiment, the pad beam 4 includes a slide rail, and the bottom of the support frame assembly is provided with a plurality of column feet 5, which are engaged in the slide rail.

[0044] The support beam 4 has dedicated support points for connecting and positioning the column base 5. The column base 5 is fixed to the slide rail with bolts at the support points; when the column base 5 is not at a support point, the bolts are removed and the column base 5 slides along the slide rail.

[0045] Preferably, a sliding limit is provided at the bottom of the column base 5 to lock into the slide of the pad beam 4, preventing longitudinal overturning and ensuring the safety of the support moving along the pad beam 4.

[0046] The universal sliding support of this application includes a pad beam 4 containing a slide rail and column feet 5 at the bottom of the support frame assembly. When stable support is required, the support points can be connected by bolts to form a stable support structure. At non-support points, the bolts can be removed, and the column feet 5 can slide along the slide rail, allowing the universal sliding support to be removed as a whole. While forming a stable support structure, it can also be removed efficiently as a whole, greatly improving construction efficiency.

[0047] like Figure 4 As shown, in one embodiment, the overall sliding universal support also includes longitudinal beams 11 and transverse distribution beams 9. A plurality of longitudinal beams 11 are disposed on the top of the support frame assembly, and a plurality of transverse distribution beams 9 are perpendicularly intersected with the plurality of longitudinal beams 11. The bottom formwork assembly 12 is supported on the top surface of the transverse distribution beams 9, and the longitudinal beams 11 extend beyond the bottom surface of the segment beam 2 of the pier top area to be poured on all four sides.

[0048] The overall sliding universal support of this application has a staggered vertical structure formed by the longitudinal beam 11 and the transverse distribution beam 9, which stably supports the bottom formwork assembly 12. The structure is stable. The longitudinal beam 11 extends beyond the bottom surface of the segment beam 2 in the pier top area to be poured on all four sides, leaving space for manual operation.

[0049] Furthermore, in one embodiment, the overall sliding universal support also includes steel wedges 10, with a plurality of steel wedges 10 disposed between the transverse distribution beam 9 and the longitudinal beam 11 to form an inclination that matches the bottom surface of the segmental beam 2 in the pier top area to be poured.

[0050] The overall sliding universal support of this application not only allows for fine height adjustment of the steel wedge block 10 through the top steel wedge block, but also meets the inclination requirements of the bottom surface of the segment beam 2 in various pier top areas; by adjusting the height of the top surface of the support through the steel wedge block 10, it can better adapt to the inclination angle requirements of the bottom of the beam than a general support.

[0051] Furthermore, in one embodiment, the overall sliding universal support also includes a safety railing 13. The safety railing 13 is set on the edge of the longitudinal beam 11 and is set vertically upward. The safety railing 13 encloses and forms a safe operating platform for high-altitude operations, preventing accidents to construction personnel and reserving sufficient operating space for template-related work.

[0052] Furthermore, in one embodiment, the bottom of the safety guardrail 13 is hinged to the edge of the longitudinal beam 11 and can be flipped relative to the longitudinal beam 11.

[0053] This application's universal sliding support system uses a rotating safety railing. During formwork construction, it flips upwards for fixation; during removal, it flips downwards to avoid obstruction. This solves the problem of the support system being unable to be completely removed from one side due to railing height limitations, thus reducing the amount of disassembly and assembly work.

[0054] like Figure 1 , Figure 2 and Figure 5 As shown, the support frame assembly includes adjusting section steel pipe piles 6 and standard assembly section 7. The standard assembly section 7 is manufactured according to a set height, and the adjusting section steel pipe piles 6 are manufactured according to the height of the beam web. In actual use, the height of the crossbeam is achieved by using one or more standard assembly sections 7, and any insufficient height is supplemented by adjusting section steel pipe piles 6.

[0055] The overall sliding universal support of this application, with the adjustment section steel pipe pile 6 and the standard assembly section 7 of the support used together, can quickly form the required support frame assembly. The prefabricated installation effectively reduces the amount of high-altitude work. In use, the support assembly is formed first and then hoisted. The prefabricated processing and hoisting of the support reduces the work of high-altitude assembly and welding, improves work efficiency, and reduces construction safety risks.

[0056] Furthermore, the support frame assembly also includes a connecting system 8, which is fixedly installed between the standard assembly sections 7 of the support frame, further improving the overall structural stability.

[0057] Furthermore, in one embodiment, the standard assembly section 7 of the support includes a standard section steel pipe pile 71, a flange 72, an inter-section connection system 73, and a pile cap 74. The flange 72 is disposed at the bottom end of the standard section steel pipe pile 71, the pile cap 74 is disposed at the top end of the standard section steel pipe pile 71, and the inter-section connection system 73 is disposed between two adjacent standard section steel pipe piles 71.

[0058] The support frame is fabricated into standard assembly sections 7 before being hoisted as a whole. The number of standard assembly sections 7 can be determined according to the height of the piers. Standard assembly sections are connected to each other between sections, and the bottom standard assembly sections are connected to the adjusting section steel pipes 6 using flanges. Based on the overall height of the support frame, it is advisable to connect the adjusting section steel pipes 6 to the standard assembly sections for stability before hoisting the whole frame. The adjusting section steel pipes are welded to the column base to improve the ease of installation and alignment.

[0059] The scaffolding can be pulled outwards from one side of the bridge or pushed inwards for installation. Alternatively, it can be hoisted as a whole and then installed with column foot limiting devices before being pulled outwards. This construction method eliminates the cumbersome disassembly and assembly procedures of the scaffolding, improves work efficiency, and reduces construction costs.

[0060] Furthermore, in one embodiment, after the segmental beam 2 in the pier top area is poured, the pad beam 4 is extended laterally, and the overall sliding universal support slides as a whole.

[0061] Specifically, before the overall sliding universal support is moved out laterally, the pad beam 4 must be extended laterally, and temporary support must be added to the bottom of the pad beam 4. The elevation of the top surface of the extended pad beam must be consistent with the elevation of the top surface of the pad beam at the design position of the support. Then, the support is removed as a whole by sliding the column base using equipment.

[0062] Specifically, before the entire sliding universal support is moved horizontally and removed, the guardrail needs to be lowered first.

[0063] Specifically, when constructing a segment of a continuous beam (block 0), the supports on the left and right sides of the pier are hoisted as a whole using prefabricated methods and connected as a whole by the connecting system 8. When dismantling, the overall connection should be released first, and then the left and right sides should be moved out laterally as a whole.

[0064] The overall sliding universal support of this application, by utilizing the prefabricated standard section 7 and the column base sliding removal design, can eliminate the need for multiple and complicated support disassembly and assembly work during construction. The problem of insufficient support surface at the bottom of the support can be solved by the pad beam 4, while avoiding the occurrence of uneven settlement. The longitudinal beam 11 can be adjusted at any angle by the top steel wedge block 10, making it suitable for different tilt angle requirements of the beam bottom. It can meet the safety, efficiency, convenience and economy requirements of lightweight bridge construction.
