All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0020] The present utility model provides a formwork support for cast-in-place box girders herein. As Figures 1 - 6 shown, it can be implemented in the following manner; the formwork support has a base 1, a main frame sleeve 2, a cross bar 3, a diagonal bar 4, a connecting rod 5, and a U-shaped adjusting seat tooth tube 6; among them, there are four groups of bases 1, and above each base 1, there are multiple main frame sleeves 2 and connecting rods 5 corresponding thereto, thereby forming four groups of support units. The support units are connected by cross bars 3 and diagonal bars 4. The outer surface of the base 1 has an external thread, the inner wall of the main frame sleeve 2 has an internal thread, the outer surface of the connecting rod 5 has an external thread, and the outer surface of the U-shaped adjusting seat tooth tube 6 has an external thread. The adjacent main frame sleeves 2 up and down are connected into a whole by the connecting rod 5. The lowermost main frame sleeve 2 is sleeved on the base 1, and the U-shaped adjusting seat tooth tube 6 is sleeved on the uppermost main frame sleeve 2. A U-shaped adjusting seat 8 is fixed at the top of the U-shaped adjusting seat tooth tube 6. In this application, the formwork support is realized by matching multiple groups of main frame sleeves 2 and connecting rods 5, and the number of main frame sleeves 2 can be determined according to specific situations, which is convenient for raising or adjusting the overall height of the support.

[0021] In this application, each group of main frame sleeves 2 has a wrench 21 and a connecting disc 22 that are integrally formed or welded. Multiple wedge holes 23 are provided on the connecting disc 22; both ends of the cross bar 3 and the diagonal bar 4 are respectively connected with a wedge through joint 7. The wedge through joint 7 has a disc bayonet 71 and a wedge through socket 72; the wedge through joint 7 of the cross bar 3 is sleeved into the corresponding connecting disc 22. At the position of the disc bayonet 71, the front end of the cross bar head abuts against the main frame sleeve, and then a wedge 9 is passed through the wedge hole 23 for fixation; the wedge through joint 7 of the diagonal bar 4 is sleeved into the position of the connecting disc, so that the front end of the diagonal bar head abuts against the main frame sleeve, and then a wedge 9 is passed through the wedge hole and tightened for fixation. In this application, when disassembling or assembling the main frame sleeve 2, the rotation of the main frame sleeve 2 can be completed through the wrench 21 that is integrally formed or welded with the main frame sleeve 2, which is convenient for loosening or tightening the main frame sleeve 2, thereby making the erection of the support easier; moreover, both the cross bar 3 and the diagonal bar 4 are fixed by wedge inserts, which not only makes the operation easy but also ensures its overall strength.

[0022] In this application, the cross bar 3 needs to be installed one layer every 150 cm and assembled according to the actual height.

[0023] In this application, a pipe wrench 61 is welded to the middle of the U-shaped adjustment seat pipe 6, which facilitates the adjustment of the U-shaped adjustment seat pipe 6 through the pipe wrench 61.

[0024] The process of scaffolding erection will be described as follows:

[0025] (1) Construction preparation: First, according to the approved special construction plan, technical and safety disclosures are given to the project management personnel and construction workers, as well as the hazards and construction key points are informed. The construction tools are prepared completely, the site drainage measures are improved, and the operation site is processed according to the plan.

[0026] (2) Measuring and lofting positioning: The surveyors use a total station to loft the vertical projection line of the beam slab on the foundation, and use a ink line to pop out the marking line. The on-site technician determines the center line of the bottom row according to the projection line and makes a mark with paint. The disk buckle scaffolds are symmetrically arranged on both sides according to the center line.

[0027] (3) Steps for erecting the disk buckle scaffold

[0028] 1) Adjusting the base: After lofting, arrange the bases to the fixed points, and put the main frame sleeve part of the standard base upward into the upper part of the adjustment seat. The lower edge of the standard base needs to be completely placed into the groove of the wrench stress plane.

[0029] 2) The first layer of crossbar: Put the crossbar head into the small hole position of the disk so that the front end of the crossbar head abuts against the main frame round pipe, and then penetrate the small hole with a wedge and knock it tightly to fix.

[0030] 3) Flat main frame: The main frames without connecting rods installed are collectively called flat main frames. Insert the long end of the flat main frame into the sleeve of the standard base. The flat main frame is only used for the first layer of lapping, and the main frames are used from the second layer upwards.

[0031] 4) Diagonal bar: Assemble all the diagonal bars in the clockwise or counterclockwise direction. Put the diagonal bar into the large hole position of the disk so that the front end of the diagonal bar head abuts against the main frame round pipe, and then penetrate the large hole with a wedge and knock it tightly to fix. The diagonal bar has a directionality, and it cannot be lapped if the directions are opposite.

[0032] Install the third layer of crossbars and the second layer of diagonal bars lapped in the same direction as the first layer according to the above steps. If the first layer is assembled in the counterclockwise direction, the diagonal bars above the second layer also need to be assembled in the counterclockwise direction.

[0033] 5) Main frame: The main frames are connected with square pipes, and just insert the connecting rod into the lower layer of pipes. If the main frame pins need to be used, it is necessary to check whether the disk alignment holes are in the same direction.

[0034] 6) Crossbar: The crossbars need to be installed one layer every 150 cm and assembled according to the actual height. The crossbars in the top layer of the support frame (i.e., below the U-shaped adjustment seat) shall not exceed a step distance of 100 cm.

[0035] 7) Third-layer diagonal bar: Lap the third-layer diagonal bar in the same direction as the first and second layers.

[0036] 8) U-shaped adjustment seat: Insert the tooth tube of the U-shaped adjustment seat into the main frame tube, and then adjust it to the required height with a wrench.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
