Abstract
Description
Technical Field
[0001] This invention relates to an assembly platform, and more particularly to a Bailey bridge support type mobile formwork bridge building machine assembly platform, belonging to the technical field of mobile formwork bridge building machines. Background Technology
[0002] Traditionally, the assembly of mobile formwork bridge-building machines can only begin on already constructed bridge abutments. This is because the rear outriggers of the mobile formwork must be supported on the existing abutments, and the rear outriggers generate significant backward pushing forces during longitudinal movement of the mobile formwork. Ordinary bridge pier locations do not provide suitable support for the rear outriggers. This limitation affects the site selection for assembling mobile formwork bridge-building machines during on-site bridge construction, thus restricting their application in long and large bridges. Summary of the Invention
[0003] The purpose of this invention is to provide a Bailey bridge support-type mobile formwork bridge-building machine assembly platform, which can solve the problem that existing ordinary bridge pier locations cannot provide support positions for the rear outriggers. This limitation affects the site selection for assembling mobile formwork bridge-building machines in on-site bridge construction, thus restricting the application of mobile formwork bridge-building machines in long and large bridges.
[0004] To achieve the above objectives, the main technical solution adopted by the present invention includes: a Bailey bridge support type mobile formwork bridge building machine assembly platform, comprising a bridge abutment, a pier body cast at the upper end of the bridge abutment, a first Bailey support frame and a second Bailey support frame respectively arranged on both sides of the pier body, a second I-beam installed at the upper end of the first Bailey support frame, a Bailey truss longitudinal beam arranged at the upper end of the second I-beam, sleepers laid at the upper end of the Bailey truss longitudinal beam, a first I-beam installed at the upper end of the second Bailey support frame, a steel plate laid at the upper end of the first I-beam, a mobile formwork main steel beam arranged at the upper end of the steel plate and sleepers, and rear support legs of the mobile formwork arranged on both sides of the lower end of the main steel beam of the mobile formwork, the rear support legs of the mobile formwork being in contact with the steel plate.
[0005] Preferably, a first side support pier and a second side support pier are cast on both sides of the upper end of the bridge pier, and the first side support pier and the second side support pier are located on both sides of the bridge pier body.

[0007] Preferably, pier body embedded connectors are pre-embedded on both sides of the pier body, and the pier body embedded connectors on both sides are respectively connected to the first Bailey support frame and the second Bailey support frame.
[0008] Preferably, a diagonal brace is welded to one side of the first I-beam, and the upper end of the diagonal brace is connected to the steel plate.
[0009] Preferably, the first I-beam is an I56a I-beam and the second I-beam is an I25b I-beam.
[0010] Preferably, the sleeper is made of 5 layers of 2 cm thick wooden boards stacked together.
[0011] Preferably, brackets are provided on both sides of the upper end of the first Bailey support frame.
[0012] This invention has at least the following beneficial effects:

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0021] like Figure 1-3 As shown, a Bailey bridge support type mobile formwork bridge construction machine assembly platform includes a bridge abutment 1, with a pier body 6 cast on the upper end of the bridge abutment 1. A first Bailey support frame 4 and a second Bailey support frame 5 are respectively installed on both sides of the pier body 6. A second I-beam 15 is installed on the upper end of the first Bailey support frame 4, and a Bailey truss longitudinal beam 11 is installed on the upper end of the second I-beam 15. Sleepers 10 are laid on the upper end of the Bailey truss longitudinal beam 11. A first I-beam 12 is installed on the upper end of the second Bailey support frame 5, and a steel plate 13 is laid on the upper end of the first I-beam 12. A mobile formwork assembly platform is installed on the upper ends of the steel plate 13 and the sleepers 10. The main steel beam 8 of the movable formwork frame is provided with rear support legs 9 on both sides of the lower end of the main steel beam 8 of the movable formwork frame. The rear support legs 9 of the movable formwork frame are attached to the steel plate 13. The upper end of the bridge abutment 1 is respectively cast with the first side support 2 and the second side support 3. The first side support 2 and the second side support 3 are located on both sides of the bridge pier body 6. The first side support 2 and the second side support 3 are respectively connected to the lower end of the first Bailey support frame 4 and the second Bailey support frame 5. The first side support 2 and the second side support 3 are made of concrete. The first I-beam 12 is an I56a I-beam and the second I-beam 15 is an I25b I-beam.
[0022] In this embodiment, the Bailey support type mobile formwork bridge building machine assembly platform can effectively solve the problem of longitudinal movement of the bridge building machine, enabling the bridge building machine to be assembled and implemented from any pier of the bridge, which is safe, reliable and easy to operate.
[0023] Both sides of the pier body 6 are pre-embedded with pier body pre-embedded connectors 7. The pier body pre-embedded connectors 7 on both sides are connected to the first Bailey support frame 4 and the second Bailey support frame 5 respectively. One side of the first I-beam 12 is welded with a diagonal brace 14. The upper end of the diagonal brace 14 is connected to the steel plate 13. The sleeper 10 is made of 5 layers of 2CM thick wooden boards. Both sides of the upper end of the first Bailey support frame 4 are equipped with supports.
[0024] In this embodiment, the pre-embedded connector 7 in the pier body allows the first Bailey support frame 4 and the second Bailey support frame 5 to be connected to the pier body 6, enhancing the stability of the first Bailey support frame 4 and the second Bailey support frame 5. Under the action of the support, the support effect of the Bailey truss longitudinal beam 11 is further strengthened, preventing the Bailey truss longitudinal beam 11 from deforming. Under the action of the diagonal bracing steel 14, the support of the steel plate 13 is strengthened.
[0025] The construction steps of a Bailey bridge support-type mobile formwork bridge-building machine assembly platform are as follows:
[0026] Step 1: Treat the first side abutment 2 and the second side abutment 3 in advance. If the bridge abutment 1 is not large enough, replace the first side abutment 2 and the second side abutment 3 to meet the bearing capacity requirements. Calculate the height of the first side abutment 2 and the second side abutment 3 based on the back-calculated elevation, and then pour the first side abutment 2 and the second side abutment 3.
[0027] Step 2: Install the first Bailey support frame 4 and the second Bailey support frame 5. The first Bailey support frame 4 and the second Bailey support frame 5 are composed of 5 or 6 vertical Baileys, with 3 groups of 6 Baileys in each layer, and 3 welded and fixed to the pre-embedded connectors of the pier body in the middle.
[0028] Part Three: Install Bailey truss longitudinal beam 11. Bailey truss longitudinal beam 11 is assembled from 1 single beam + 4 sets + 1 single-layer Bailey beam. The length is determined based on the specific conditions of the bridge. The middle section of Bailey truss longitudinal beam 11 consists of 4 sets of 45cm wide Bailey beams, 30m long, connected to each other by continuous [10 channel steel after hoisting. On each side of the main Bailey beam, there is one 1.5m wide Bailey set, connected to the middle Bailey beam by [8 channel steel scissor bracing, requiring additional fabrication. Reinforcement is added every 3m at the ends and in the middle. During hoisting, it is combined with the middle 45cm wide Bailey sets.
[0029] Part 4: Install sleepers 10. Sleepers 10 consist of 5 layers. The bottom layer of wooden planks is arranged horizontally, and the top 4 layers are arranged in a crisscross pattern to ensure that sleepers 10 press on the 4 sets of Bailey panels in the middle, and the 4 sets are stressed at the same time.
[0030] Part 5: Set up a support platform for the rear outriggers of the mobile formwork bridge-building machine. The rear outriggers 9 and auxiliary supports of the mobile formwork are placed on a 3cm thick steel plate 13. Ten first I-beams 12 (I56a I-beams) are arranged under the steel plate 13. Each I-beam is supported by a single Bailey bridge section. The cantilevered I-beams are supported by 10 20 channel steels on one side of the Bailey bridge section. The Bailey bridge section transfers the load to the Bailey bridge support.
