[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-Figure 9 As shown:

[0040] An integral sliding bracket cast-in-place mold formed in one step, comprising an integral sliding inner mold system 2 and a side mold system 4, the side mold system 4 is docked with the bottom mold 3, and the inner mold system 2 and the fixed mold 1 together form the main structure of the cast-in-place operation;

[0041] The inner mold system 2 includes a first inner mold 203, a second inner mold 204 and a third inner mold 205. The second inner mold 204 and the third inner mold 205 are symmetrically arranged on both sides of the first inner mold 203. The first inner mold 203 and the second inner mold 204 are hingedly connected to each other at their edges, and the second inner mold 204 and the third inner mold 205 are hingedly connected to each other at their edges.

[0042] In this embodiment, the traditional cast-in-place box girder support method generally uses a strip foundation with a spiral tube as the support foundation, the outer web and wing plate templates are assembled in sections using large steel templates, and the inner templates are assembled using small steel flat templates or bamboo plywood. After the construction of each hole of the simply supported box girder is completed, the spiral tube needs to be cut or extended according to the site terrain, the outer web and wing plate templates are disassembled in sections, and the inner template needs to be disassembled into small pieces and manually transported out of the box room and then transported to the next span. The traditional support cast-in-place simply supported box girder construction method has a large investment in personnel and machinery, a long template turnover time, a large template loss, and is extremely difficult to hoist the template on the side far away from the crane due to the restriction of the beam body, with a high safety risk, which is extremely unfavorable to the safety, cost and progress management of multi-span cast-in-place simply supported box girder projects;

[0043] Faced with many unfavorable factors of traditional construction methods, after extensive research and discussion, the support structure of the bracket is optimized and improved, and the assembled inner formwork system 2 and side formwork system 4 are used to realize the turnover use of the inner formwork system 2 and the side formwork system 4, thereby improving the material turnover rate. At the same time, during the turnover work, the inner formwork system 2 and the side formwork system 4 do not need to be put on the ground, which is more effective in complex environments such as gully areas with complex terrain, difficult construction of construction access roads, and inconvenient material transfer. It greatly shortens the template turnover construction time, reduces the investment in personnel and machinery, and is simple to operate with a high safety factor, which not only ensures construction safety but also reduces construction costs, with significant economic effects.

[0044] The inner form system 2 and the side form system 4 can slide as a whole, the side form system 4 is docked with the bottom form 3, and the inner form system 2 and the fixed form 1 together form the main structure of the cast-in-place operation. The inner form system 2 can be removed only when the concrete strength of the beam body reaches 75% of the design strength. When the inner form system 2 and the side form system 4 need to slide as a whole, the third inner form 205 of the inner form system 2 first rotates inward, that is, the bottom ends of the two third inner form 205 move toward each other, and then the bottom of the second inner form 204 rotates inward, and when the second inner form 204 rotates inward, it will drive the third inner form 205 to rotate together, and finally the first inner form 203 moves downward, and when the first inner form 203 moves, it drives the second inner form 204 and then drives the third inner form 205 to move downward, thereby realizing the separation of the first inner form 203, the second inner form 204 and the third inner form 205 from the beam body concrete;

[0045] The side formwork system 4 can be removed only when the concrete strength of the beam body reaches 75% of the design strength. When the side formwork system 4 slides, the side formwork system 4 is first moved downward, and then the two side formwork systems 4 are moved in opposite directions.

[0046] During the overall sliding operation of the inner formwork system 2 and the side formwork system 4, they are pulled forward by a winch, which saves time and effort in construction;

[0047] To ensure that the support foundation has sufficient bearing capacity, the mud circulation pool and the soft strata under the surface are excavated and replaced before foundation treatment. The replacement material is crushed slag, and each side is at least 0.5m wider than the support foundation. The excavator and roller are used to level and compact it. The bearing capacity is tested after compaction. Only after passing the test can the next construction process be continued. Since the construction period of cast-in-place simply supported box girders is relatively long, in order to ensure the bearing capacity of the foundation, drainage facilities should be well prepared around the support foundation to ensure that there is no water accumulation.

[0048] In an optional embodiment, a plurality of supporting beams 201 are arranged within the enclosed range when the inner mold system 2 is docked with the fixed mold 1, a pair of inner rails 2014 are commonly fixed on the top surfaces of the plurality of supporting beams 201, the top ends of the inner rails 2014 are rollingly connected to inner rollers 2013, and the top ends of the inner rollers 2013 are fixedly connected to the fixed body 202.

[0049] In this embodiment, the support beam 201 serves as a basis for installing the inner rail 2014 , so that the fixed body 202 can move on the inner rail 2014 through the inner roller 2013 .

[0050] In an optional embodiment, a second adjustable support bracket 11 is fixedly connected to the bottom of the support beam 201, and the second adjustable support bracket 11 is fixedly connected to the support beam 301 through a first drainage hole 101 opened on the fixed mold 1 and a second drainage hole 303 opened on the bottom mold 3.

[0051] In this embodiment, since the support beam 201 is arranged within the enclosed range when the inner mold system 2 and the fixed mold 1 are connected, a second adjustable support bracket 11 is required as a connecting piece to realize the fixed installation of the support beam 201. The second adjustable support bracket 11 can adjust the height of the support beam 201. After the position of the support beam 201 is adjusted, the position of the support beam 201 can be locked by the second adjustable support bracket 11. The support beam 201 is installed using the first drainage hole 101 and the second drainage hole 303, which can avoid additional holes in the fixed mold 1 and the bottom mold 3.

[0052] In an optional embodiment, the top end of the support beam 301 is fixedly connected to the surface of the bottom mold 3 , and the bottom end of the support beam 301 is fixedly connected to the square tube cross beam 6 through a plurality of I-beams 7 .

[0053] In this embodiment, the support beam 301 can provide support for the bottom mold 3. The combination of the square tube cross beam 6 and the I-beam 7 facilitates the adjustment and installation of the position of the bottom mold 3 and reduces costs. The square tube cross beam 6 is installed on the bracket foundation through a rigid unloading block.

[0054] In an optional embodiment, a lifting cylinder 206 is fixedly installed on the top of the fixed body 202, and the top of the lifting cylinder 206 is fixedly installed on the back water surface of the first inner template 203. A first adjusting cylinder 207 is hinged between the first inner template 203 and the second inner template 204, and a second adjusting cylinder 208 is hinged between the second inner template 204 and the third inner template 205.

[0055] In this embodiment, when the inner mold system 2 is removed, the second regulating cylinder 208 is first controlled to contract, then the first regulating cylinder 207 is controlled to contract, and finally the lifting cylinder 206 is controlled to contract.

[0056] In an optional embodiment, the inner mold system 2 also includes a first fixed adjusting rod 209, a second fixed adjusting rod 2011 and a third fixed adjusting rod 2012 for stabilizing the cast-in-place working structure, one end of the first fixed adjusting rod 209 is hingedly connected to the back water surface of the first inner mold 203, both ends of the second fixed adjusting rod 2011 are respectively hingedly connected to the back water surface of the second inner mold 204 and one end of the fixed body 202, and both ends of the third fixed adjusting rod 2012 are respectively hingedly connected to the back water surface of the third inner mold 205 and one end of the fixed body 202.

[0057] In this embodiment, the lifting cylinder 206, the first adjusting cylinder 207 and the second adjusting cylinder 208 are mainly used to control the rotation of the first inner template 203, the second inner template 204 and the third inner template 205. Simply relying on the cylinder cannot achieve stable fixation of the first inner template 203, the second inner template 204 and the third inner template 205. On the basis of cost considerations, secondary reinforcement of the adjusting rod can increase the structural strength of the first inner template 203, the second inner template 204 and the third inner template 205, thereby improving its load-bearing capacity, and preventing its deformation and bending, thereby improving its service life and cast-in-place molding quality. When the lifting cylinder 206, the first adjusting cylinder 207 and the second adjusting cylinder 208 are working, the first fixed adjusting rod 209, the second fixed adjusting rod 2011 and the third fixed adjusting rod 2012 are all removed, and the first fixed adjusting rod 209, the second fixed adjusting rod 2011 and the third fixed adjusting rod are changed their lengths manually and the lengths are locked.

[0058] In an optional embodiment, a plurality of rotating brackets 2010 are fixedly connected to the top end of the supporting beam 201 , and the other end of the first fixed adjustment rod 209 is hingedly connected to the rotating bracket 2010 .

[0059] In this embodiment, the other end of the first fixed adjustment rod 209 is hinged to the supporting beam 201, which can improve the load-bearing capacity of the first inner template 203. On the basis of the stable position of the first inner template 203, the second inner template 204 and the third inner template 205 can be better fixed. Since the second inner template 204 and the third inner template 205 are fixed relative to the fixed body 202, the fixed body 202 itself has the function of moving and has poor stability. However, the tedious work of disassembling the second fixed adjustment rod 2011 and the third fixed adjustment rod 2012 can be avoided, reducing the work intensity. The first fixed adjustment rod 209 can directly fix the first inner template 203 relatively to the supporting beam 201, thereby improving the overall structural stability.

[0060] In an optional embodiment, the side formwork system 4 includes a side formwork 401 and a side beam 402, the back water surface of the side formwork 401 is fixedly connected to the side beam 402, the outer side of the side beam 402 is fixedly connected to a support frame 403, a first adjustable support bracket 9 is fixedly installed between the bottom end surface of the support frame 403 and the top end surface of the square tube cross beam 6, and a mechanical jack 10 is fixedly installed between the top end surface of the support frame 403 and the top back water surface of the side formwork 401.

[0061] In this embodiment, the position and angle of the support frame 403 can be adjusted by the first adjustable support bracket 9, so as to adjust the relative position of the side template 401 and the bottom template 3. The mechanical jack 10 can be set to support the top of the side template 401, thereby improving the load-bearing capacity of the side template 401.

[0062] In an optional embodiment, a pull rod 404 for fixing the side beam 402 and the support beam 301 is installed on the outer side of the side beam 402, a reserved hole 302 is opened at one end of the support beam 301, and one end of the pull rod 404 passes through the reserved hole 302 and is connected to the support beam 301.

[0063] In this embodiment, during cast-in-place work, concrete has a relatively large weight. It is difficult to ensure the docking stability between the side formwork 401 and the bottom formwork 3 by simply relying on the first adjustable support bracket 9 as support. Under the extrusion pressure of the concrete, the gap between the side formwork 401 and the bottom formwork 3 will increase. By connecting the side beam 402 and the support beam 301 through the pull rod 404, it is possible to avoid the gap between the side formwork 401 and the bottom formwork 3 from increasing under the pressure of the concrete. Of course, when sliding the side formwork system 4, the pull rod 404 needs to be removed.

[0064] In an optional embodiment, an outer steel rail 8 is fixedly connected to the top surface of the square tube crossbeam 6, and a sliding vehicle 5 rolls on the top of the outer steel rail 8. The sliding vehicle 5 includes a frame 501 and an outer roller 502. The bottom of the frame 501 is fixedly connected to the outer roller 502, and the outer surface of the outer roller 502 rolls with the outer surface of the outer steel rail 8. A slide groove 503 for accommodating the bottom end of the support frame 403 is provided on the top of the frame 501, and a rolling shaft 504 is rotatably connected to the bottom of the slide groove 503 of the frame 501.

[0065] In this embodiment, when pouring concrete, the support frame 403 is fixed to the square tube crossbeam 6 by the first adjustable support bracket 9, and the sliding vehicle 5 does not support the support frame 403, but the support frame 403 is still located in the slide groove 503 of the frame 501. When the side form system 4 needs to slide, the support frame 403 is lowered by adjusting the length of the first adjustable support bracket 9 until the support frame 403 contacts the transverse rolling shaft 504. Therefore, during the work of pouring concrete, a certain gap is required between the support frame 403 and the transverse rolling shaft 504. After the support frame 403 contacts the transverse rolling shaft 504, the side form system 4 is moved laterally. The setting of the transverse rolling shaft 504 facilitates the movement of the support frame 403. The support frame 403 is driven by a hand winch to move horizontally by 5-10 cm, so that the side form system 4 is completely separated from the beam body, and then the side form system 4 can be driven by the sliding vehicle 5 to move along the outer rail 8.

[0066] Finally, it should be noted that the first adjustable support bracket 9, the mechanical jack 10, the second adjustable support bracket 11, the first fixed adjustment rod 209, the second fixed adjustment rod 2011, and the third fixed adjustment rod 2012 all have existing mechanical structures for adjusting the height and locking at the height.

[0067] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
