Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction support, in particular to a wedge-shaped support structure. Background Art
[0002] Fish belly beam refers to a common beam type in building structures, also known as fish belly crane beam, its name comes from its shape similar to the belly of a fish. The characteristic of this beam is that the lower part of the beam is concave inwards, forming an arched structure, which can increase the bearing capacity of the beam and reduce the deadweight of the beam to a certain extent; fish belly beams are commonly used in bridges, large-span buildings and other projects that require large structural support because they can provide greater bearing capacity and structural stability.
[0003] The traditional fish belly beam lap joint method is complicated to construct, and the mortise and tenon connection or simple nail connection may not provide sufficient contact area to support the load-bearing requirements of the beam, which means that the stress distribution at the connection part is uneven, resulting in insufficient strength. Insufficient strength of the beam connection may cause damage to the beam itself, which in turn affects the structural integrity of the entire building or bridge, requiring more frequent repairs and higher maintenance costs. At the same time, it also cannot solve the problem of the secondary pouring cement slurry penetrating into the surface of the first phase of concrete pouring and affecting the appearance. If the secondary pouring cement slurry penetrates into the cement slurry on the surface of the first phase of concrete pouring, it will cause potholes on the surface of the fish belly beam after solidification. In severe cases, it will produce a certain bending moment. Finally, when it is filled, the cement slurry solidified on the surface of the fish belly beam will cause uneven force on the local structure and form a structural weak point, which will not only affect the appearance of the fish belly beam but also endanger the service life of the fish belly beam. Therefore, it needs to be solved urgently. Summary of the invention
[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a wedge-shaped support structure. The utility model provides a support combination including an arc support, a wedge-shaped support, a wedge-shaped block and a support column to provide sufficient contact area to meet the load-bearing requirements of the fish belly beam. At the same time, the solid wedge-shaped block and the wedge-shaped support can also effectively prevent the local leakage of cement slurry when pouring the fish belly beam, so as to avoid the local unevenness of the fish belly beam and the generation of local stress, thereby improving the service life and aesthetics of the fish belly beam.

[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] 1. The utility model provides a sufficient contact area for the arc-shaped part of the fish belly beam through a support combination consisting of an arc-shaped support, a wedge-shaped support, a wedge-shaped block and a support column, thereby ensuring the strength of the fish belly beam; and the solid wedge-shaped support and the wedge-shaped block can provide sufficient supporting force for the arc-shaped support to effectively avoid separation between the arc-shaped support and the fish belly beam during construction, and can also effectively prevent the template from expanding and leaking cement slurry during the pouring process. The leakage of cement slurry is further reduced due to the buffering of the wedge-shaped block and the wedge-shaped support, so as to improve the aesthetics of the surface of the fish belly beam, and at the same time, it can also prevent the solidified cement slurry on the surface of the fish belly beam from causing uneven stress on the local structure, forming the possibility of structural weak points, and delaying the service life of the fish belly beam.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] Embodiment 1:
[0037] See also Figure 1-Figure 6 In the embodiment of the utility model, a wedge-shaped support structure is provided, which includes a plurality of support combinations, the support combination including an arc-shaped support 1, a wedge-shaped support 2, a wedge-shaped block 3 and a support column 4, the upper arc surface of the arc-shaped support 1 is fitted with the external fish belly beam 8, the wedge-shaped support 2 is arranged at the top of the lower arc surface of the arc-shaped support 1, and a support column 4 is arranged on one side of the wedge-shaped support 2, and the support column 4 is used to connect with the external structure, and the wedge-shaped block 3 is arranged at the bottom of the lower arc surface of the arc-shaped support 1, and the contact surfaces of the wedge-shaped support 2 and the wedge-shaped block 3 with the arc-shaped support 1 are both arc-shaped; using a plurality of support combinations, the complexity of casting templates for the external fish belly beam 8 is reduced, so that the construction of the templates for the fish belly beam 8 is more convenient, and the wedge-shaped support 2 and the wedge-shaped block 3 can provide support force for the arc-shaped support 1, and can also effectively slow down the falling of concrete leaked locally, so as to improve the aesthetics and safety of the fish belly beam 8 during the secondary casting.
[0038] The support structure also includes an annular support 5, which is horizontally arranged to connect multiple support combinations. The support combinations are vertically arranged, and the support combinations and the annular support 5 are perpendicular to each other. The multiple support combinations are connected by using the annular support 5. The number of support combinations is set according to the width of the fish belly beam 8 to be cast, so that the multiple support combinations are connected into an integrated structure through the annular support 5, which is more convenient to use. The annular support 5 is connected to the lower end surface of the support column 4, and a mounting hole is opened on the wedge block 3. The annular support 5 passes through the wedge block 3 through the mounting hole. The annular support 5 can be used to enhance the strength of each support combination to extend its service life. The part of the annular support 5 located between two adjacent mounting holes can also be used to build an operating platform. The support structure is located at the arc-shaped bottom on one side of the fish belly beam 8, and the arc-shaped bottom on the other side of the fish belly beam 8 is also symmetrically provided with the support structure. When building the operating platform, the two ends of the wooden board are placed on the annular supports 5 of the two support structures to facilitate the construction personnel to walk and improve work efficiency.
[0039] A platform beam 6 is also provided between two adjacent support assemblies, and both ends of the platform beam 6 are connected to the support columns 4. The platform beam 6 and the support columns 4 are perpendicular to each other, so that the platform beam 6 is also in a horizontal state. During the construction process, wooden boards can also be built on the platform beam 6 to form an operating platform to facilitate the construction of construction workers. At the same time, since the platform beam 6 and the annular support 5 are located on horizontal planes at different heights, the operating platform constructed therefrom also allows construction workers to have a larger construction range, making the construction more efficient and convenient.
[0040] The arc support 1, wedge-shaped support 2, support column 4, annular support 5 and platform beam 6 are all made of steel and wood, and the wedge block 3 is made of wooden beam. Due to the good structure and force-bearing performance of steel and wood and wooden beam, using them as support structure is easy to install and disassemble, and has high safety performance. At the same time, compared with the existing traditional fish belly beam 8 construction method or the support structure using steel structure, the support structure can be adjusted according to different application scenarios, and it is also more cost-effective; the support column 4, wedge-shaped support 2, annular support 5, wedge block 3, platform beam 6 and arc support 1 are fixedly connected together, and can be directly installed when assembled on site, which is convenient for workers to work. It should be noted that when pouring the fish belly beam 8, the support structure plays a more connecting role rather than the main load-bearing part. Therefore, the use of steel and wood and wooden beams will not affect the service life of the support structure or affect the pouring of the fish belly beam 8.

[0043] The mounting hole is a circular hole, and the annular support 5 that passes through the wedge block 3 is a circular column. The cooperation between the circular hole and the circular column can achieve the maximum contact area between the wedge block 3 and the annular support 5, so as to improve the strength of the support structure and extend the service life.
[0044] Embodiment three:

[0046] A plurality of mounting grooves 51 are provided on the annular support 5, and the mounting grooves 51 are located between two adjacent support assemblies. In the present embodiment, the mounting grooves 51 are square grooves, and the portion of the annular support 5 connected thereto is a circular column. The mounting grooves 51 enable the wooden board built thereon to be placed more stably, and the formed operating platform is safer.
[0047] Embodiment 4:
[0048] Reference Figure 9-10 In the embodiment of the present invention, based on a wedge-shaped support structure of the first embodiment, the fourth embodiment further makes the following improvements:
[0049] The corresponding support structures arranged on both sides of the fish belly beam 8 are connected by multiple connecting beams 7, and the two ends of the connecting beams 7 are respectively connected to the lower end surface of the arc support 1.
