Description
Technical Field
[0001] The present application relates to the field of bridge construction equipment, and in particular to a pier-free large-span Bailey beam combined support structure system. Background Art
[0002] Cast-in-place construction is a construction technique that directly pours concrete on the construction site, and is often used for large building structures such as bridges, large slabs, industrial buildings, etc. This method allows the concrete structure to be formed in situ, rather than being manufactured in a precast plant and then transported to the site.
[0003] However, due to the low bending stiffness of the Bailey beam, the span of the conventional support structure generally does not exceed 12~15m, and a steel pipe pile support pier must be set in the middle of the span. The insertion of steel sheet piles requires professional equipment and has requirements for geological conditions. It is difficult to construct in strata such as pebble overburden layers. Especially in special terrain conditions such as shallow riverbeds and V-shaped canyons where professional piling equipment cannot reach, the support construction is difficult or even impossible, resulting in the problem that the span of the conventional steel pipe pile Bailey beam cast-in-place support cannot meet the construction requirements.

[0005] The present application provides a pier-free large-span Bailey beam combined support structure system adopts the following technical solutions:
[0006] A pier-free large-span Bailey beam combined support structure system, comprising
[0007] Bailey beams, used to carry loads;
[0008] A support, provided with a first connecting portion and a receiving portion, wherein the first connecting portion is provided with a latch hole, the support is connected to the Bailey beam pin shaft through the latch hole, and the receiving portion is provided on the support, and the receiving portion is used to receive the Bailey beam;
[0009] The support assembly includes a cap, and the cap is connected to the support to support the Bailey beam.
[0010] By adopting the above technical solution, firstly, the connection part of the support can connect two adjacent Bailey frames, so that the two adjacent Bailey frames form a whole, which increases the rigidity and stability of the whole structure; then, through the connection part of the support, the load of the adjacent Bailey frames can be evenly transferred to the support assembly, that is, the pedestal, and finally the load is safely transferred to the ground. This load distribution mechanism significantly improves the bending stiffness of the Bailey frame, so that the entire pier-free large-span Bailey beam combined support structure system can adapt to larger span requirements; furthermore, compared with the traditional support structure, there is no need to use large construction machinery when setting the pedestal, so it is suitable for special terrain conditions that traditional supports are difficult to cope with, such as shallow riverbeds, V-shaped canyons, etc., to improve the problem of small span of existing support structures under special terrain conditions.
[0011] Preferably, the support assembly also includes a pier top distribution beam and a steel pipe pile, the pier top distribution beam is connected to the support to support the Bailey beam, one end of the steel pipe pile is connected to the pedestal, and the other end of the steel pipe pile is connected to the pier top distribution beam to support the pier top distribution beam.
[0012] By adopting the above technical solution, steel pipe piles are used to connect the base and the pier top distribution beam, which can effectively extend the span and allow the Bailey beam to span a larger distance without the need for additional piers, so that the pier-free large-span Bailey beam combined support structure system can adapt to different terrains and geological conditions, especially in areas where traditional supports are difficult to construct, such as shallow riverbeds, V-shaped canyons, etc.; the pier top distribution beam disperses the load of the Bailey beam to several steel pipe piles through the support, which not only improves the bearing capacity, but also reduces the force on a single support point, thereby improving the safety of the entire structure, increasing the span of the pier-free large-span Bailey beam combined support structure system, and further improving the problem of the small span of the existing support structure under special terrain conditions.

Especially when bearing large loads or under adverse environmental conditions, it can effectively improve the bending stiffness of the Bailey beam, so that the pier-free large-span Bailey beam combined support structure system can be applied to harsh terrains that span large distances without setting intermediate piers, such as shallow riverbeds, V-shaped canyons, etc., and further improve the problem of small spans of existing support structures under special terrain conditions.
[0017] Preferably, the connecting assembly also includes a connecting socket, which is arranged between the vertical rod and the Bailey beam, one side of the connecting socket is connected to the Bailey beam, and the side of the connecting socket away from the Bailey beam is connected to an end of the vertical rod close to the Bailey beam.
[0018] By adopting the above technical solution, the connecting bracket allows precise positioning between the vertical rod and the Bailey beam, simplifies the connection method between the vertical rod and the Bailey beam, ensures more accurate and effective force transmission, and more effectively transmits the load borne by the Bailey beam to the entire support system, thereby improving the overall stiffness of the structure, making the pier-free large-span Bailey beam combined support structure system suitable for spanning a large distance without setting intermediate piers in harsh terrain, such as shallow riverbeds, V-shaped canyons, etc., and further improves the problem of small span of existing support structures under special terrain conditions.

[0020] By adopting the above technical solution, the connection method of the lattice structure provides additional support points for the steel pipe piles, so that a more solid frame is formed between the steel pipe piles, thereby enhancing the stability of the entire pierless large-span Bailey beam combined support structure system when facing lateral loads, and improving the bending resistance of the entire pierless large-span Bailey beam combined support structure system, thereby increasing the versatility of the pierless large-span Bailey beam combined support structure system.
[0021] Preferably, the lattice structure is a self-stabilizing lattice, and one side of the self-stabilizing lattice is connected to a plurality of the steel pipe piles.
[0022] By adopting the above technical solution, the self-stabilizing lattice structure can maintain stability without relying on external support, and no additional temporary support is required during the construction process, which simplifies the construction steps and speeds up the construction speed, especially at construction sites with complex terrain or limited space, and enhances the stability and safety of the pier-free large-span Bailey beam combined support structure system.
[0023] Preferably, the cap is provided with embedded parts, and the embedded parts are used to connect the cap and the steel pipe pile.
[0024] By adopting the above technical solution, the embedded parts provide a solid connection point between the pedestal and the steel pipe piles, ensuring the stability and reliability of the entire pier-free large-span Bailey beam combined support structure system; and, by setting the embedded parts, the need for on-site welding or other temporary fixing measures can be reduced, allowing the quick disassembly between the pedestal and the steel pipe piles and the recovery of the steel pipe piles, thereby increasing the utilization rate of materials.

[0037] The following is combined with Figure 1-7 This application is described in further detail.
[0038] The cast-in-place construction of the support method is widely used in bridge engineering. The conventional cast-in-place structural forms of bridge supports mainly include: bowl buckle support, disc buckle support, Bailey beam steel pipe support and other structural forms, but these support forms have obvious disadvantages and limited use conditions, such as: the bowl buckle support itself has low rigidity, the support erection is cumbersome, the engineering volume is large, the bearing capacity of the foundation at the bridge site is high, and it cannot be used in deep soft silt geology, riverbed geology, etc. At the same time, the support erection height is limited, and the cast-in-place beam with a higher pier cannot be used; the disc buckle support is cumbersome, the engineering volume is large, the cost is high, the bearing capacity of the foundation at the bridge site is high, it cannot be used in soft silt geology, riverbed geology, etc., the support erection height is limited, and the cast-in-place beam with a higher pier cannot be used; the span of the conventional Bailey beam steel pipe support is restricted by the bending stiffness of the Bailey beam, the span is small, especially in geological conditions such as V-shaped canyons and shallow silt layers, where it is difficult to insert steel pipe piles when construction equipment cannot reach, and the conventional Bailey beam steel pipe support cannot be constructed.
[0039] The present application embodiment discloses a pier-free large-span Bailey beam combined support structure system. Figure 1 The pier-free large-span Bailey beam combined support structure system includes a support component 3, a Bailey beam 1, a support 2 and a connection component 4.
[0040] like Figure 2 As shown, the support assembly 3 includes a cap 31 , embedded parts 32 , steel pipe piles 34 , a pier top distribution beam 33 and an adjustment pad 35 .
[0041] In the embodiment of the present application, the operator can cast the cap 31 at the required position on site in combination with the operation requirements and the operation environment, and set the embedded parts 32 on the top of the cap 31. Compared with the traditional support structure, no large-scale construction machinery is required when setting the cap 31, so it is suitable for special terrain conditions that traditional brackets are difficult to cope with, such as shallow riverbeds, V-shaped canyons, etc., to improve the problem of small span of existing bracket structures under special terrain conditions; after the construction of the cap 31 is completed, the steel pipe piles 34 are installed on the cap 31 through the embedded parts 32, for example: on the cap A plurality of threaded steel bar embedded parts 32 are vertically arranged on the top of 31, and the steel pipe piles 34 are installed on the pedestal 31 through the threaded steel bar embedded parts 32 and the connecting sleeves; the embedded parts 32 provide a solid connection point between the pedestal 31 and the steel pipe piles 34, ensuring the stability and reliability of the entire pier-free large-span Bailey beam combined support structure system; and, by providing the embedded parts 32, the need for on-site welding or other temporary fixing measures can be reduced, allowing the quick disassembly between the pedestal 31 and the steel pipe piles 34 and the recovery of the steel pipe piles 34, thereby increasing the utilization rate of materials.
[0042] A number of steel pipe piles 34 are provided, and the pier top distribution beam 33 is provided on the top of the number of steel pipe piles 34, and is connected to the number of steel pipe piles 34 by means including but not limited to welding, bolt connection, flange connection or pin connection, so as to disperse the load of the pier top distribution beam 33 to the number of steel pipe piles 34, thereby improving the bearing capacity of the pier-free large-span Bailey beam combined support structure system, reducing the stress on a single support point, thereby improving the safety of the entire structure, increasing the span of the pier-free large-span Bailey beam combined support structure system, and further improving the problem of the small span of the existing support structure under special terrain conditions.
[0043] It should be noted that the connection method between the pier top distribution beam 33 and the steel pipe pile 34 needs to be set according to the actual situation. For example, when it is necessary to recycle construction materials, a steel wedge can be set between the pier top distribution beam 33 and the steel pipe pile 34. In the embodiment of the present application, an adjustment pad 35 is set on the top of each steel pipe pile 34 to facilitate construction personnel to fine-tune the height of the pier top distribution beam 33 relative to the steel pipe pile 34, so that the pierless large-span Bailey beam combined support structure system can adapt to different construction requirements and ground conditions, and ensure the horizontal and vertical alignment of the pierless large-span Bailey beam combined support structure system; several adjustment pads 35 also play a role in evenly dispersing the load of the pier top distribution beam 33 and transferring it to the steel pipe pile 34, reducing local stress concentration, thereby improving the stability and durability of the entire pierless large-span Bailey beam combined support structure system.
[0044] The adjustment pad 35 can also provide additional adaptability for the pierless large-span Bailey beam combined support structure system, especially in uneven or changing terrain, ensuring the stability of the pierless large-span Bailey beam combined support structure system and reducing the workload of foundation treatment, such as errors in pouring the base, or inevitable uniform or uneven ground settlement caused by the deadweight of the base and / or steel pipe piles 34, so as to adjust the settlement difference of the pierless large-span Bailey beam combined support structure system and improve the adaptability and flexibility of the pierless large-span Bailey beam combined support structure system.
[0045] like Figure 2 As shown, several steel pipe piles 34 are connected by a self-stabilizing lattice structure 5. In the embodiment of the present application, the self-stabilizing lattice is a lattice steel beam, and one side of the lattice structure 5 is detachably connected to one side of several steel pipe piles 34, thereby providing additional support points for several steel pipe piles 34, so that several steel pipe piles 34 form a stable whole, enhance the stability of the entire pierless large-span Bailey beam combined support structure system when facing lateral loads, and improve the bending resistance of the entire pierless large-span Bailey beam combined support structure system, and increase the versatility of the pierless large-span Bailey beam combined support structure system.
[0046] At the same time, the self-stabilizing lattice structure 5 can maintain stability without relying on external support, and no additional temporary support is required during the construction process, especially at construction sites with complex terrain or limited space, which simplifies the construction steps and speeds up the construction speed, thereby improving the stability and safety of the pier-free large-span Bailey beam combined support structure system.
[0047] like Figure 2 and Figure 3 As shown, a plurality of Bailey beams 1 are provided, and two adjacent Bailey beams 1 are connected by a support 2 .
[0048] Specifically, referring to Figs. Figure 5 The support 2 is provided with a first connection part 21 and a receiving part 23. The bottom of the support 2 is connected to the pier top distribution beam 33. The first connection part 21 is provided with a plurality of pin holes 24. The support 2 is connected to the two Bailey beams 1 through the plurality of pin holes 24, so that the two adjacent Bailey frames form a whole, which increases the rigidity and stability of the entire structure. There are two receiving parts 23, which are respectively arranged on both sides of the support 2. The two receiving parts 23 abut against the two adjacent Bailey beams 1, so that the loads of the two Bailey frames can be evenly transferred to the support assembly 3, that is, the pedestal 31, and finally the load is safely transferred to the ground. This load distribution mechanism significantly improves the bending stiffness of the Bailey frame, so that the entire pier-free large-span Bailey beam combined support structure system can adapt to larger span requirements.
[0049] It should be noted that the support 2 is also provided with a second connecting portion 22, which extends outward and protrudes from the support 2.

[0050] Furthermore, the support 2 is connected to the Bailey beam 1 as a whole through a latch, and the damage caused to the Bailey beam 1 during the installation and disassembly process can be ignored, so that the Bailey beam 1 can be reused, thereby reducing the construction cost.

The tie rod 42 effectively transfers the load from the Bailey beam 1 to the support 2 through the vertical rod 41, and then transfers it to the cap 31 and the steel pipe pile 34 through the support 2, thereby dispersing the load, reducing the force of a single component, and enhancing the stability of the structure, especially when it is subjected to a large load or Under adverse environmental conditions, the bending stiffness of the Bailey beam 1 can be effectively improved; and the connecting bracket 43 can ensure that the force transmission is more accurate and effective, and the load borne by the Bailey beam 1 can be more effectively transmitted to the support 2, thereby improving the overall stiffness of the structure, reducing the mid-span steel pipe piles 34 in the supporting structure, and adapting to the construction of cast-in-place beams with a span of 20 to 40 meters, so that the pier-free large-span Bailey beam combined support structure system can be applied to harsh terrains that span a large distance without setting intermediate piers, such as shallow riverbeds, V-shaped canyons, etc., and further improve the problem of small spans of existing support structures under special terrain conditions.
[0052] It should be noted that, in the embodiment of the present application, the connecting component 4 has two connecting structures.

The connection base 43 is detachably connected to the Bailey beam 1. One end of the vertical rod 41 is connected to the side of the connection base 43 away from the Bailey beam 1. The other end of the vertical rod 41 is connected to the second connection parts 22 of two adjacent supports 2 through the two pull rods 42.
[0055] The first connection structure has higher structural stability and bearing capacity, is suitable for large-span or heavy-load construction environments, and is set in the middle position of the pier-free large-span Bailey beam combined support structure system. The second connection structure simplifies the construction and reduces the use of materials. It is suitable for space-constrained needs and is set at both ends of the pier-free large-span Bailey beam combined support structure system. It should be noted that the user can use the first connection structure or the second connection structure to set the connection component 4 according to actual construction needs.
[0056] Specifically, the construction method of the pier-free large-span Bailey beam combined support structure system is as follows: the construction personnel cast the pedestal 31, and bury the embedded parts 32 on the pedestal 31, and after the construction of the pedestal 31 is completed, the steel pipe piles 34 are installed on the pedestal 31, and the adjustment pads 35 and the pier top distribution beam 33 are set on the top of the steel pipe piles 34; the holder 43, the support 2, the vertical rod 41, the pull rod 42 and the Bailey beam 1 are connected by pins to form a truss structure, and the assembled truss structure is installed on the pier top distribution beam 33, and the bottom formwork and side formwork structures required for construction are set on the truss structure and the pre-stressed support is piled, the pre-arch of the support is adjusted, the steel bars are tied and the concrete beam is cast, the concrete box beam is maintained and prestressed, the side formwork and the truss structure are removed, and finally the support is removed to complete the construction of the concrete box beam.
