[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] The utility model embodiment provides a steel box girder support construction structure, referring to Figure 1 and Figure 2 As shown, the steel box girder support construction structure includes: a support bracket 10, a support 20, a wedge block 30 and a horse plate 40;

[0033] The upper steel box girder 01 and the lower steel box girder 02 are arranged opposite to each other in the vertical direction; the support bracket 10 is arranged on the lower steel box girder 02, and the support 20 is arranged on the support bracket 10;

[0034] The wedge block 30 is arranged between the support 20 and the upper steel box girder 01 , and the horse plate 40 surrounds the wedge block 30 and is connected to the support 20 .

[0035] Before the sliding construction of the upper steel box girder 01, the support 20 and the wedge block 30 are arranged on one side of the supporting bracket 10;

[0036] After the sliding construction of the upper steel box girder 01 , the support 20 and the wedge block 30 are arranged on the top of the supporting bracket 10 .

[0037] It is understandable that before the upper steel box girder 01 is slipped, the support 20 is placed next to the location where it needs to be installed, so as not to affect the construction of the upper steel box girder 01. Furthermore, a wedge block 30 is also provided on the top of the support 20. The support bracket 10 is provided at the installation location, that is, before the upper steel box girder 01 is slipped, the support 20 and the support bracket 10 are arranged adjacent to each other.

[0038] Furthermore, a pad stone reinforcement 50 is provided on the lower steel box girder 02, and the pad stone reinforcement 50 and the support 20 are located in the same vertical direction;

[0039] The support bracket 10 is arranged around the pad stone reinforcement 50 .

[0040] The bottom of the installation position of the support 20 is a pad stone. After the upper steel box girder 01 is slidably constructed, the pad stone reinforcement 50 used for casting the pad stone is welded first, and then a rectangular support bracket 10 is welded around the pad stone reinforcement 50.

[0041] Furthermore, after the sliding construction of the upper steel box girder 01 , the support 20 and the wedge block 30 are connected to the lifting device with the stretching direction close to the side of the supporting bracket 10 .

[0042] A temporary pad 60 is provided on one side of the support bracket 10 , and the temporary pad 60 is equal in height to the support bracket 10 .

[0043] Before the sliding construction of the upper steel box girder 01 , the support 20 and the wedge block 30 are arranged on the top of the temporary pad 60 .

[0044] Before the sliding construction of the upper steel box girder 01, the support 20 is placed on one side of the installation position. After the sliding construction of the upper steel box girder 01, the support 20 is hoisted from one side to the installation position by the hoisting device. In the vertical direction, the projection of the support 20 falls within the range of the projection of the support bracket 10. In other words, the support bracket 10 can fully support the support 20. The hoisting device can be a hand winch. At the same time, in order for the support 20 to be able to move horizontally to the installation position, a temporary pad 60 can be set on one side of the support bracket 10. The temporary pad 60 is equal in height to the support bracket 10, which facilitates the hoisting of the support 20. It should be noted that during the hoisting process, the wedge block 30 arranged on the top of the support 20 moves together with the support 20, and the wedge block 30 includes a plurality of wedge blocks 30, which are evenly arranged around the top of the support 20.

[0045] Further, after the support 20 and the wedge block 30 are moved into place, the support 20 and the wedge block 30 are welded, and the horse plate 40 is welded around the wedge block 30 and welded to the bottom of the upper steel box girder 01. After the support is supported by the support bracket 10, the pad stone template is set around the pad stone steel bar 50. Concrete is poured into the pad stone template. After the pad stone concrete is cured, grouting is performed between the pad stone concrete and the support 10. Finally, the horse plate 40 is removed, the support bracket 10 is removed, and the wedge block 30 is connected to the upper steel box girder 01. The support 20 is installed.

[0046] The construction method of the steel box girder support construction structure is as follows:

[0047] ① The upper steel box girder 01 sliding track occupies the support 20 position, cuts off the steel bars that conflict with the pad stone, and retains sufficient lap welding length;

[0048] ② Place the support 20 next to the part where it needs to be installed;

[0049] ③ The upper steel box girder 01 slides into place;

[0050] ④ Remove the upper steel box girder 01 sliding track and install the pad stone reinforcement 50;

[0051] ⑤ Use angle steel to weld a support bracket 10 around the pad stone steel bar 50, use a hand chain hoist to move the side support 20 and the wedge block 30 to the specified position, and support them with the support bracket 10;

[0052] ⑥ Use the horse plate 40 to fix the wedge block 30 and the support 20;

[0053] ⑦Install the pad stone formwork and pour the pad stone concrete;

[0054] ⑧ After the curing of the pad stone concrete is completed, grouting is performed between the pad stone concrete and the support 20;

[0055] ⑨ Remove the horse plate 40, remove the supporting bracket 10, and weld the wedge block 30 to the bottom of the upper steel box beam 01.

[0056] In summary, the steel box girder support construction structure provided by the utility model achieves at least the following beneficial effects:

[0057] In the embodiment provided by the utility model, before the upper steel box girder is slidably constructed, the support is preset at one side of the installation position, and a support bracket is set at the installation position as a support structure of the support. After the upper steel box girder is slidably constructed, the support is placed at the installation position by horizontal hoisting, and the shim casting and support installation are performed in sequence. Finally, the relevant support structure is removed. The utility model is simple and convenient to operate, saves time and effort, and is more conducive to construction in the narrow space between the upper and lower steel box girders.
