Description

Technical fields:

[0001] This invention relates to the technical field of building equipment, and more specifically to a support system for box girder support and wet joint casting of steel structures. Background technology:

[0002] In existing bridge construction, end beams are typically installed at the top of the columns, and then beam slabs are installed on top of the end beams. These are all precast components, which are then assembled and fixed in place later. However, in some bridge constructions, the specifications and shape of the end beams need to be changed according to the actual installation, making it impossible to manufacture precast components. In such cases, the end beams need to be cast in place. This requires corresponding equipment to support the beam slabs above during construction, and existing bridge erecting machines cannot meet this construction requirement. Summary of the Invention:

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a support equipment for box girder support and wet joint casting steel structure. It can be placed on the corresponding bearing platform to support the beams and formwork above it, thereby enabling the on-site casting of the connecting end beams and meeting the construction requirements.

[0004] The solution of the present invention to the aforementioned technical problem is:

[0005] A support frame for box girder support and wet joint casting steel structure includes multiple bearing platforms. A column is fixed in the middle of the top surface of the bearing platform. Side lifting legs are installed at the front and rear of the left and right sides of the bearing platform. Jacks are installed on the top surface of the side lifting legs. Electric anti-roller sets are fixed on the top surface of the jacks. The same load-bearing beam is installed on all corresponding electric anti-roller sets in the same horizontal row. All templates are pressed against the corresponding load-bearing beams. The beams to be processed are pressed against the corresponding templates. Connecting templates are provided on the top and bottom surfaces of the joints between two adjacent beams.

[0006] A connecting beam is cast between the adjacent beams at the front and rear, and the bottom surface of the connecting beam is fixed to the top surface of the corresponding column.

[0007] The side lifting outrigger includes an outer sleeve column and an inner sleeve column. The inner sleeve column is inserted into the outer sleeve column, and the inner sleeve column and the outer sleeve column cooperate with each other. The bottom end plate of the inner sleeve column presses against the top surface of the support platform. Multiple vertically arranged positioning through holes are formed on the side plate of the inner sleeve column. An upper positioning through hole is also formed on the corresponding side plate of the outer sleeve column. The positioning through hole corresponds to the upper positioning through hole. The same positioning pin is inserted into one of the positioning through holes and the upper positioning through hole.

[0008] A horizontal bar is fixed on the upper outer wall of the outer sleeve column of the leftmost and rightmost side lifting outriggers. A chain hoist is hung at the bottom of the horizontal bar, and the bottom hook of the chain hoist is hung on the hanging plate fixed on the side wall of the corresponding inner sleeve column.

[0009] An operating platform is fixed between the outer columns of the four adjacent side lifting legs of the two adjacent left and right pedestals in the middle. A chain hoist is hung on the bottom right side of the operating platform near the corresponding side lifting leg. The bottom hook of the chain hoist is hung on a hanging plate fixed on the side wall of the corresponding inner sleeve column.

[0010] A connecting beam is fixed between the outer sleeve columns of the two adjacent side lifting legs on the top surface of the pier.

[0011] A horizontal connecting frame is fixed between two adjacent load-bearing beams below the joint between two adjacent beams in the middle section. Multiple movable seats are fixed on the horizontal connecting frame. An upper connecting sleeve is movably connected to the movable seat via a hinge shaft. A vertical screw is screwed onto the upper connecting sleeve. The upper part of the vertical screw is inserted into the corresponding joint. The top of the vertical screw extends out of the top surface of the joint. An upper connecting template is fixed to the top of the vertical screw. The upper connecting template presses against the top surface of the two adjacent beams and covers the top surface of the joint. A connecting template is also fixed to the upper part of the vertical screw. The top surface of the connecting template presses against the bottom surface of the adjacent edges of the two adjacent beams and covers the bottom surface of the joint.

[0012] Support rods are provided between the left and right adjacent load-bearing beams of the foundation. The left and right ends of the support rods are movably connected to support seats through hinge shafts.

[0023] For example, see below. Figures 1 to 7 As shown, a support system for box girder support and wet joint casting steel structure includes multiple bearing platforms 10. A column 11 is fixed to the center of the top surface of each bearing platform 10. Side lifting legs 20 are installed on the front and rear of both sides of the bearing platforms 10. Each side lifting leg 20 includes an outer sleeve column 21 and an inner sleeve column 22. The inner sleeve column 22 is inserted into the outer sleeve column 21, and the inner sleeve column 22 cooperates with the outer sleeve column 21. The bottom end plate of the inner sleeve column 22 presses against the top surface of the bearing platform 10. Multiple vertically arranged positioning through holes 23 are formed on the side plate of the inner sleeve column 22. A corresponding upper positioning through hole 24 is also formed on the corresponding side plate of the outer sleeve column 21. The positioning through holes 23 and the upper positioning through hole 24 correspond to each other. A positioning through hole 23 and an upper positioning through hole 24 are fitted with the same positioning pin. Furthermore, a horizontal rod 25 is fixed on the upper outer wall of the outer sleeve column 21 of the leftmost and rightmost side lifting legs 20. A chain hoist 50 is hung at the bottom of the horizontal rod 25. The bottom hook of the chain hoist 50 is hung on a hanging plate fixed on the side wall of the corresponding inner sleeve column 22. An operating platform 60 is fixed between the outer sleeve columns 21 of the four adjacent side lifting legs 20 of the two adjacent left and right support platforms 10 in the middle. A chain hoist 50 is hung on the bottom surface of the operating platform 60 near the right side of the corresponding side lifting leg 20. The bottom hook of the chain hoist 50 is hung on a hanging plate fixed on the side wall of the corresponding inner sleeve column 22.

[0024] This structure allows the hook of the chain hoist 50 to be hooked onto the hanging plate of the corresponding inner sleeve column 22 during use. This allows the corresponding positioning pin to be pulled out. Then, by manually pulling the control part of the chain hoist 50, the height of the inner sleeve column 22 along the outer sleeve column 21 can be adjusted to meet the usage requirements. After the position is adjusted, the positioning pin is inserted into the corresponding positioning through hole 23 and the upper positioning through hole 24 to achieve positioning.

[0025] Furthermore, a jack 30 is fixed to the top surface of the outer sleeve column 21 of the side lifting outrigger 20, and an electric anti-roller assembly 40 is fixed to the top surface of the jack 30. The same load-bearing beam 100 is installed on all corresponding electric anti-roller assemblies 40 in the same horizontal row. When there is still a certain height difference after the corresponding positioning through hole 23 and the upper positioning through hole 24 are fixed by positioning pins, the height of the top surface of the jack 30 can be adjusted to ensure that the top surface of the transmission wheel 42 of the lower part of the electric anti-roller assembly 40 presses against the bottom surface of the load-bearing beam 100 to achieve support.

[0026] All templates 200 are pressed against the corresponding load-bearing beams 100, and the beams 300 to be processed are pressed against the corresponding templates 200. The top and bottom surfaces of the joints between two adjacent beams 300 are provided with connecting templates 400.

[0027] A connecting end beam 500 is cast between the adjacent beams 300 at the front and rear, and the bottom surface of the connecting end beam 500 is fixed to the top surface of the corresponding column 11.

[0028] Furthermore, the electric anti-roller assembly 40 includes a support frame 41, the base plate of the support frame 41 is fixed on the top surface of the jack 30, and side support plates are fixed on the left and right sides of the top surface of the base plate of the support frame 41. The upper front and rear sides of the inner sidewall of the side support plates are movably connected to the transmission wheel 42 through a hinge shaft. The bottom surface of the upper transmission wheel 42 corresponds to the top surface of the transverse rod fixed on the top surface of the bottom plate of the load-bearing beam 100. A transmission shaft 43 is provided at the lower front and rear sides between the two side support plates. The two ends of the transmission shaft 43 are fixed on the two side support plates. A lower transmission wheel 46 is movably connected to the transmission shaft 43 through a bearing. The left and right ends of the lower transmission wheel 46 are formed with external teeth, which mesh with the teeth formed on the outer side of the corresponding upper transmission wheel 42.

[0029] A drive motor 44 is fixed on the outer wall of one of the side support plates. The output shaft of the drive motor 44 passes through the corresponding side support plate and is fixed with a drive gear 45. The drive gear 45 meshes with the external teeth on the corresponding side of the two lower transmission wheels 46. The top surface of the lower transmission wheel 46 corresponds to the bottom surface of the bottom plate of the load-bearing beam 100.

[0030] Furthermore, a connecting beam 1 is fixed between the outer sleeve columns 21 of the two adjacent side lifting legs 20 on the top surface of the support platform 10.

[0031] Furthermore, a horizontal connecting frame 2 is fixed between two adjacent load-bearing beams 100 below the joint between two adjacent beams 300 in the middle. Multiple movable seats 3 are fixed on the horizontal connecting frame 2. An upper connecting sleeve 4 is movably connected to the movable seat 3 through a hinge shaft. A vertical screw 5 is screwed onto the upper connecting sleeve 4. The upper part of the vertical screw 5 is inserted into the corresponding joint. The top of the vertical screw 5 extends out of the top surface of the joint. An upper connecting template 400 is fixed to the top of the vertical screw 5. The upper connecting template 400 presses against the top surface of the two adjacent beams 300 and covers the top surface of the joint. A connecting template 400 is also fixed to the upper part of the vertical screw 5. The top surface of the connecting template 400 presses against the bottom surface of the adjacent edges of the two adjacent beams 300 and covers the bottom surface of the joint.

[0032] Furthermore, a support rod 6 is provided between the left and right adjacent load-bearing beams 100 of the foundation 10. The left and right ends of the support rod 6 are movably connected to the support seat 7 through the hinge shaft. The support seat 7 is welded and fixed to one side wall of the corresponding load-bearing beam 100.

[0033] Furthermore, an outer transverse beam 101 is fixed to the outer wall of the load-bearing beam 100 at the leftmost or rightmost outermost position. A first fixing seat 102 is fixed to the top surface of the outer transverse beam 101. One end of an inclined support rod 105 is movably connected to the upper part of the first fixing seat 102. The other end of the inclined support rod 105 is movably connected to a second connecting seat 104. The bottom surface of the outer side of the outer bending rod 103 is fixed to the second connecting seat 104. The bottom surface of the inner end of the outer bending rod 103 presses against the top surface of the corresponding load-bearing beam 100. The top surface of the inner end of the outer bending rod 103 presses against the bottom surface of the outer side of the corresponding beam slab 300. The outer bending rod 103 cooperates with the outer wall of the corresponding beam slab 300 and presses against the wall of the outer side of the leftmost or rightmost beam slab 300. It can support the outer edge of the leftmost or rightmost beam 300. After the leftmost or rightmost beam 300 is installed and poured, the hinge shaft of the inclined support rod 105 and the first fixed seat 102 can be disassembled. By adjusting the corresponding jack 30, its top surface can be lowered, and the outer bending rod 103 can be removed.

[0034] In this embodiment, the load-bearing beam 100 is an I-beam.

[0035] Working principle: In this embodiment, corresponding side lifting outriggers 20, jacks 30, and other components described above are installed on the top surfaces of the corresponding multiple support platforms 10. Figure 1As shown, the left side of the foundation 10 is equipped with side lifting outriggers 20 and other mechanisms, while the right side of the foundation 10 has a fixed auxiliary support column, which does not have side lifting outriggers 20 and other mechanisms installed on it. Multiple clamps 700 are fixed on its upper outer wall, and the bottom surface of the corresponding load-bearing beam 100 presses against the corresponding top clamp 700. The same row of foundation 10s on the right side is equipped with side lifting outriggers 20 and other mechanisms. The same row of foundation 10s on the right side is also equipped with an auxiliary support column, which does not have side lifting outriggers 20 and other mechanisms installed on it. Multiple clamps 700 are fixed on its upper outer wall, and the bottom surface of the corresponding load-bearing beam 100 presses against the corresponding top clamp 700 to achieve support. The same row of foundation 10s on the right side is equipped with side lifting outriggers 20 and other mechanisms.

[0036] The support platform 10, which is equipped with mechanisms such as side lifting outriggers 20, has a column 11 fixed on it as the main support.

[0037] At this point, there is a joint between two adjacent beams 300 on the left and right sides, which is located between the corresponding upper and lower connecting templates 400, where concrete can be poured to achieve the connection.

[0038] The portion between two adjacent beams 300 is located above multiple columns 11 or multiple secondary support columns. Each of the corresponding columns 11 or secondary support columns is equipped with a casting template, which can be used to cast the connecting end beam 500, thus achieving cast-in-place construction. This eliminates the need to install precast end beams; instead, the connecting end beam 500 is directly cast in place, meeting the building requirements.

[0039] After this part of the pouring is completed, this embodiment requires the hole to be made so that the subsequent beams and slabs 300 can be placed and poured.

[0040] like Figure 8 The row of foundations 10 behind it is the first foundation a. The row of foundations 10 after the first foundation a, separated by one foundation 10 (this upper fixed secondary support column), is the second foundation b. The corresponding rows of foundations 10 are named in this order as the third foundation c, the fourth foundation d, and the fifth foundation e.

[0041] The corresponding components such as the side lifting support leg 20 behind the first platform a are the sixth support leg group 91, the components such as the side lifting support leg 20 in front of the first platform a are the fifth support leg group 92, the components such as the side lifting support leg 20 behind the second platform b are the fourth support leg group 93, the components such as the side lifting support leg 20 in front of the second platform b are the third support leg group 94, the components such as the side lifting support leg 20 behind the third platform c are the second support leg group 95, and the components such as the side lifting support leg 20 in front of the third platform c are the first support leg group 96.

[0042] The process of passing through the hole is as follows: (1) The fourth leg group 93 retracts the corresponding inner sleeve column 22 by manually operating the control part of the corresponding chain hoist 50. Then, the bottom surface of the transmission wheel 42 on the upper part of the corresponding electric anti-roll wheel group 40 presses against the top surface of the horizontal bar fixed on the bottom plate of the load-bearing beam 100 and moves along the load-bearing beam 100 to the middle part of the second platform b. Then, the corresponding inner sleeve column 22 is extended by manually operating the control part of the corresponding chain hoist 50, and its bottom plate presses against the top surface of the second platform b.

[0043] (2) Move the fifth leg assembly 92 to the top surface of the rear of the second platform b in the same way after telescoping.

[0044] (3) Move the second leg assembly 95 to the top surface of the middle part of the first support platform a in the same way.

[0045] (4) In the same way, the third leg assembly 94 is extended and moved to the top surface of the rear part of the first support platform a.

[0046] (5) In the same way, the fourth leg assembly 93 is extended and moved to the top surface of the front part of the second platform b.

[0047] (6) Move the fifth leg assembly 92 to the top surface of the rear of the second platform b in the same way after telescoping.

[0048] (7) Move the fifth leg assembly 92 to the top surface of the middle part of the second platform b in the same way after telescoping.

[0049] (8) In the same way, the sixth leg assembly 91 is extended and moved to the top surface of the middle part of the first platform a in front of the first platform a, and then moved to the top surface of the rear part of the second platform b.

[0050] (9) Disassemble the load-bearing beam 100 and the related components of the already poured beam slab 300 and the connecting end crossbeam 500, and disassemble some related connecting templates 400 and templates 200. At this time, the load-bearing beam 100 is pressed against the top surface of the transmission wheel 42 at the bottom of the corresponding electric anti-roller set 40. Through the operation of the corresponding electric anti-roller set 40 and the operation of the lower transmission wheel 42, all the corresponding load-bearing beams 100 are moved forward a certain position, so that the front end exceeds the fourth pier d.

[0051] (10) Using the same method as before, move the first leg group 96 to the top surface of the front part of the fourth pier d. Then, the subsequent second leg group 95, third leg group 94, fifth leg group 92 and sixth leg group 91 move one position forward to replace the position of the previous leg group, thus realizing the movement of one position. In the above way, all the leg groups are moved to the third pier c, the fourth pier d and the fifth pier e to complete the through hole movement. Then, install the beam slab 300, the formwork 200 and the connecting end crossbeam 500, as well as install various components, so that the subsequent pouring can be realized.

[0052] During the process of passing through the hole, multiple clamps 700 are installed on the upper part of the auxiliary support column, and the bottom surface of the corresponding load-bearing beam 100 presses against the corresponding top clamp 700 to achieve auxiliary support.
