Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to a side formwork for bridge construction with a cable-beam anchorage block. Background Technique

[0002] A cable-stayed bridge, also known as a cable-stayed bridge, is a kind of bridge in which the main beam is directly pulled on the bridge tower by many stay cables. It is a structural system composed of a pressurized tower, a tensioned cable and a beam body that bears bending. It can be regarded as a multi-span elastic support continuous beam with stay cables replacing piers. It can reduce the bending moment in the beam body, lower the building height, reduce the structural weight and save materials. A cable-stayed bridge mainly consists of a cable tower, a main beam and stay cables.

[0003] As a large-span bridge form, the stay cables of a cable-stayed bridge undertake the important functions of transmitting the deck load and fixing the deck position. Therefore, the anchorage of the stay cables becomes an important link in the construction process. The position of the stay cables in the beam body changes for each segment of the continuous beam. Therefore, the position of the cable-beam anchorage block on each segment of the continuous beam is variable. The existing construction method for the cable-beam anchorage block segment in cantilever construction is as follows: move the standard formwork a certain distance along the transverse direction of the beam body, and reserve enough space to build a wooden formwork for pouring the cable-beam anchorage block.

[0004] The above pouring scheme for the cable-beam anchorage block currently has the following problems: for each segment that needs to pour the cable-beam anchorage block, during the construction process, it is necessary to repeatedly build a wooden formwork on site according to the position of the cable-beam anchorage block. The on-site production process of the wooden formwork is cumbersome and the pouring effect is not good; the upper part of the side formwork is in a cantilever state, there is a risk of overturning; the construction personnel are located inside the side formwork, there are great safety hazards. Content of the Utility Model

[0005] In view of this, the utility model provides a side formwork for bridge construction with a cable-beam anchorage block. The first part of the side formwork is set as a split structure, which consists of a cable-beam anchorage block form and multiple groups of standard forms. During the pouring construction process, the arrangement positions of the cable-beam anchorage block form and multiple groups of standard forms along the longitudinal direction of the beam body can be adjusted according to the pouring position of the cable-beam anchorage block. There is no need to repeatedly build a wooden formwork on site. The beam body and the cable-beam anchorage block are poured synchronously, effectively ensuring the pouring effect, avoiding the risk of overturning caused by a part of the side formwork being in a cantilever state, and avoiding the safety hazards caused by construction personnel being located inside the side formwork. With fewer types of formwork, it is applicable to the pouring of the continuous beam of a cable-stayed bridge with different positions of the cable-beam anchorage block, greatly saving the construction cost.

The cable-beam anchorage block mold 11 and the standard molds 12 are used for forming the transition connection part 103 between the wing plate 101, the beam body 102, and the wing plate 101. A shaping groove 13 for forming the cable-beam anchorage block is provided inside the cable-beam anchorage block mold 11; the cable-beam anchorage block mold 11 and N groups of standard molds 12 are arranged in combination along the longitudinal direction of the bridge of the beam body 102, and N is a positive integer greater than or equal to 1; the second part 20 is used for forming the main body of the beam body 102, and the second part 20 is provided at the bottom of the first part 10.

[0033] The side formwork for bridge construction with a cable-beam anchorage block provided in the embodiment of the present application sets the first part 10 of the side formwork as a split structure, which is composed of a cable-beam anchorage block mold 11 and multiple groups of standard molds 12. During the pouring construction process, the arrangement positions of the cable-beam anchorage block mold 11 and multiple groups of standard molds 12 along the longitudinal direction of the bridge of the beam body 102 can be adjusted according to the pouring position of the cable-beam anchorage block, without the need to repeatedly build wooden formworks on site. The beam body 102 and the cable-beam anchorage block are poured synchronously, effectively ensuring the pouring effect, avoiding the risk of overturning caused by part of the side formwork being in a cantilever state, and avoiding potential safety hazards caused by construction workers being inside the side formwork. With fewer types of formworks, it is applicable to the pouring of continuous beams of cable-stayed bridges with different positions of cable-beam anchorage blocks, greatly saving the construction cost. Please refer to Figures 13 to 16 , when pouring the segment without a cable-beam anchorage block, only by replacing the cable-beam anchorage block mold 11 with a standard mold 12 can the pouring of the standard beam segment be realized, and the applicability is strong.

[0034] As Figures 1 to 3 , Figure 8 and Figure 9As shown, in one embodiment, the cable-beam anchorage block mold 11 includes a first shaping part 112 for shaping the wing plate 101 and a second shaping part 114 for shaping the transition connection part 103 between the beam body 102 and the wing plate 101; the shaping groove 13 is arranged between two side plates 14 oppositely arranged along the longitudinal direction of the beam body 102, the bottom of the side plate 14 is provided with a bottom plate 15, the side plate 14 is fixedly connected to the first shaping part 112 and the second shaping part 114, and a back plate 16 connecting the side plate 14, the bottom plate 15 and the first shaping part 112 is arranged outside the cable-beam anchorage block mold 11; a first back frame assembly 116 is arranged outside the first shaping part 112 and the second shaping part 114. The cable-beam anchorage block mold 11 with the above structural form has a simple structure, is stable and reliable, is convenient for being combined and arranged with multiple groups of standard molds 12 to form the upper half of the side mold, and forms the shaping groove of the cable-beam anchorage block through the two side plates 14, and can effectively realize the casting of the cable-beam anchorage block and the beam body together.

[0035] In one embodiment, the standard mold 12 includes a third shaping part 121 for shaping the wing plate 101 and a fourth shaping part 123 for shaping the transition connection part 103 between the beam body 102 and the wing plate 101; a second back frame assembly 125 is arranged outside the third shaping part 121 and the fourth shaping part 123. The standard mold 12 with the above structural form also has the advantages of simple structure, stability and reliability, and is convenient for flexibly adjusting the combined arrangement position with the cable-beam anchorage block mold 11, thereby greatly improving the applicability of the side mold.

[0036] As Figures 1 to 5 and Figure 10 As shown, in one embodiment, a transfer platform 30 is arranged at the top of the second part 20, and the bottoms of the cable-beam anchorage block mold 11 and the standard mold 12 are detachably connected to the transfer platform 30. Specifically, the bottoms of the first back frame assembly 116 and the second back frame assembly 125 are placed on the transfer platform 30. By arranging the transfer platform 30, on the one hand, the stable and reliable positioning installation of the cable-beam anchorage block mold 11 and the standard mold 12 can be realized, and on the other hand, when different combined arrangements of the cable-beam anchorage block mold 11 and the standard mold 12 are realized, a transition placement area can be provided, and at the same time, an operation space is provided for the operator outside the side mold, which improves the construction efficiency and greatly avoids potential safety hazards.

[0037] In one embodiment, the adapter platform 30 is in the form of a plate structure or a support frame structure formed by splicing multiple groups of support rods. The adapter platform with the above structural form has a simple structure, is stable and reliable, and is easy to install and manufacture. In one embodiment, a first sliding structure is provided on the adapter platform 30, and second sliding structures are provided at the bottoms of the first back frame assembly 116 and the second back frame assembly 125. The second sliding structures are slidably connected to the first sliding structure along the longitudinal direction of the beam body. Specifically, by providing the first sliding structure and the second sliding structure that slidably cooperate with each other along the longitudinal direction of the beam body, it is convenient to achieve stepless fine adjustment of the positions of the cable-beam anchorage block mold 11 and the standard mold 12 along the longitudinal direction of the beam body during the process of combining and arranging the cable-beam anchorage block mold 11 and the standard mold 12 along the longitudinal direction of the beam body, eliminate deviations, and facilitate the precise installation of the cable-beam anchorage block mold 11 and the standard mold 12 at the corresponding positions on the adapter platform 30, thereby improving the construction efficiency. Specifically, the first sliding structure can be one of a chute, a sliding seat, and a slider. Correspondingly, the second sliding structure can be the bottoms of the first back frame assembly 116 and the second back frame assembly 125 that are slidably connected to the chute, or a slider that is slidably connected to the sliding seat, or a sliding seat that is slidably connected to the slider.

[0038] In one embodiment, a protective structure 301 is provided on the outer side of the adapter platform 30. Obviously, by further providing a protective structure on the outer side of the adapter platform 30, the personal safety of the operators can be ensured to a great extent, and potential safety hazards can be eliminated. Specifically, the protective structure 301 can be a guardrail constructed by rod-shaped structures that are spaced apart and connected to each other, or a protective wall constructed by plate-shaped structures that are connected to each other.

[0039] In one embodiment, a third back frame assembly 21 is provided on the outer side of the second part 20, and the adapter platform 30 is fixedly connected to the third back frame assembly 21. Specifically, fixedly connecting the adapter platform 30 to the third back frame assembly 21 can ensure sufficient support force for the adapter platform 30, thereby greatly improving the stability and reliability of the entire side mold. Specifically, in one embodiment, the first back frame assembly 116, the second back frame assembly 125, and the third back frame assembly 21 can all adopt a support frame structure formed by splicing multiple groups of support rods that are spaced apart and cross-set. The various back frame assemblies with the above structural form have a simple structure, are stable and reliable, and are easy to install and manufacture.

[0040] Such as Figure 17As shown in the figure, the construction method of the side formwork for bridge construction with a cable-beam anchorage block according to the embodiments of the present application includes: S11. Configure N groups of standard formworks 12 according to the width of the cable-beam anchorage block section and the cable-beam anchorage block formwork 11 along the longitudinal direction of the bridge of the beam body 102; S12. Combine and arrange the cable-beam anchorage block formwork 11 and N groups of standard formworks 12 along the longitudinal direction of the bridge of the beam body 102 according to the position of the cable-beam anchorage block on the cable-beam anchorage block section. Obviously, in this construction method, since the side formwork of the foregoing embodiment is adopted, it has all the advantages and technical effects of the side formwork of the foregoing embodiment.

[0041] In one embodiment, the construction method further includes: S13. Adjust the overlapping width 105 of the side formwork for bridge construction with a cable-beam anchorage block along the longitudinal direction of the bridge of the beam body 102 with the already cast beam end 104 according to the width of the cable-beam anchorage block section, the cable-beam anchorage block formwork 11 and N groups of standard formworks 12 along the longitudinal direction of the bridge of the beam body 102. Specifically, after the N groups of standard formworks 12 and the cable-beam anchorage block formwork 11 are combined and arranged according to the position of the cable-beam anchorage block, it may cause the width of the N groups of standard formworks 12 and the cable-beam anchorage block formwork 11 along the longitudinal direction of the bridge of the beam body 102 to be greater than or less than the width of the cable-beam anchorage block section along the longitudinal direction of the bridge of the beam body 102. At this time, the standard formwork 12 or the cable-beam anchorage block formwork 11 on one side of the first part 10 in the side formwork can be reduced or increased, and the overlapping width between the second part 20 and the already cast beam end 104 can be adjusted to ensure that the side formwork adapts to the width of the cable-beam anchorage block section along the longitudinal direction of the bridge of the beam body 102.

[0042] According to the above embodiments, it can be seen that the side formwork for bridge construction with a cable-beam anchorage block involved in the present application does not require repeated on-site erection of wooden formworks. The beam body and the cable-beam anchorage block are cast synchronously, effectively ensuring the casting effect, avoiding the risk of overturning caused by part of the side formwork being in a cantilever state, and avoiding potential safety hazards caused by construction workers being inside the side formwork. With fewer types of formworks, it is applicable to the casting of continuous beams of cable-stayed bridges with different cable-beam anchorage block positions, greatly saving the construction cost. When casting a section without a cable-beam anchorage block, only by replacing the cable-beam anchorage block formwork with a standard formwork can the casting of a standard beam section be realized, and it has strong applicability.

[0043] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily obtained by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
