[0002] The steel-concrete composite beam is a new technology and new process with a complex structure. It consists of an open steel box beam and a precast concrete bridge deck. The two are combined together by shear nails set at the wing plate to form a steel-concrete composite beam structure, so that the steel-concrete structure can achieve common force. A reserved groove is set at the connection between the concrete precast bridge deck and the shear nail, and the reserved groove is divided into a steel grid. The minimum distance between the shear nail and the reserved groove wall is only 1.5 cm, and the positioning and welding accuracy of the shear nails during steel beam processing is required to be high. The relevant technology adopts the method of marking and fixing points. The accuracy can be guaranteed in theory, but in actual operation, due to human factors, the shear nails after welding cannot meet the requirements of horizontal position and verticality, resulting in low efficiency of steel-concrete connection positioning, damage to shear nails and other problems.

[0003] With regard to the problem in the related art that the shear studs welded on the steel box girder cannot meet the requirements of horizontal position and verticality, no effective solution has been proposed yet. Summary of the invention

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figures 1 to 4 As shown, an embodiment of the present application provides a shear nail positioning welding mold, including: a positioning plate 2 for being installed on the surface of a steel box girder wing plate 1, the positioning plate 2 is provided with a plurality of positioning holes 4 for installing the shear nail welding part, and the positioning holes 4 are distributed in an array.

[0031] In this embodiment, when welding the shear nails, the positioning plate 2 is first installed on the surface of the steel box girder wing 1. Since a plurality of positioning holes 4 for installing the shear nail welding part are provided on the positioning plate 2, the welding part at the lower end of the shear nail can be inserted into the positioning hole 4 so as to contact the surface of the steel box girder wing 1, so that the shear nail can be welded on the steel box girder wing 1 by welding equipment. Since the positioning holes 4 are distributed in an array on the positioning plate 2, the verticality of the horizontal positions of the plurality of positioning holes 4 is determined, and the shear nails are limited to the same horizontal position and verticality by the positioning holes 4, so that the shear nails can ensure the horizontal position and verticality on the steel box girder wing 1 after welding, which solves the problem in the related art that the shear nails after welding on the steel box girder cannot meet the horizontal position and verticality requirements.

[0032] like Figures 1 to 4 As shown, the thickness of the positioning hole 4 is less than or equal to the thickness of the shear nail welding part; wherein, the positioning hole 4 includes a first hole 41 for passing the shear nail cap and a second hole 43 for installing the shear nail welding part, and the first hole 41 and the second hole 43 are connected through a connecting channel 42, and the connecting channel 42 is used for sliding the shear nail column body.

[0033] Specifically, it should be noted that the thickness of the positioning hole 4 is smaller than the thickness of the shear nail welding part, which is convenient for welding during the construction process. The shear nail is welded in the second hole 43. After welding, the positioning plate 2 is moved to make the column body of the shear nail slide in the connecting channel 42 to the first hole 41, and then the positioning plate 2 is lifted upward to make the nail cap of the shear nail detach from the first hole 41, thereby completing the disassembly of the positioning plate 2.

[0034] like Figures 1 to 4 As shown, the diameter of the first hole 41 is larger than the diameter of the shear nail cap, the diameter of the second hole 43 is larger than the diameter of the shear nail welding part, and the width of the connecting channel 42 is larger than the diameter of the shear nail column.

[0035] Specifically, it should be noted that the positioning hole 4 is formed by the intersection of the first hole 41 and the second hole 43, and the connecting channel 42 is the surface where the first hole 41 and the second hole 43 intersect. The first hole 41 and the second hole 43 are both set as circular holes. The diameter of the second hole 43 is larger than the diameter of the shear nail welding part, so that the shear nail is first installed in the second hole 43 before welding. Since the length of the line connecting the intersection of the first hole 41 and the second hole 43 is larger than the diameter of the shear nail column, the positioning plate 2 can be pushed after the welding is completed, so that the column of the shear nail passes through the intersection of the first hole 41 and the second hole 43 to enter the first hole 41. Since the diameter of the first hole 41 is larger than the diameter of the shear nail cap, when the shear nail column is located in the first hole 41, the positioning plate 2 can be pulled out from bottom to top, so that the shear nail is completely separated from the positioning hole 4, and the disassembly of the positioning plate 2 is completed. Through the special-shaped positioning hole 4, the positioning welding of the shear nail can be realized, and the positioning plate 2 can be conveniently removed, and the construction efficiency is further improved.

[0036] like Figures 1 to 4 As shown, the diameter of the first hole 41 is 1.5 cm-3 cm larger than the diameter of the shear nail cap, and the diameter of the second hole 43 is 1 mm-2 mm larger than the diameter of the shear nail welding part.

[0037] Specifically, it should be noted that when the diameter of the second hole 43 is 1mm-2mm larger than the diameter of the shear nail welding part, the shear nail positioning deviation can be controlled within 0.5mm-1mm, meeting the precision requirement of the shear nail welding positioning, and at the same time, the shear nail welding part can be installed in the second hole 43. The diameter of the first hole 41 is 1.5cm-3cm larger than the diameter of the shear nail cap, which is convenient for disassembly of the positioning plate 2. The first hole 41 and the second hole 43 are distributed left and right.

[0038] The first holes 41 and the second holes 43 are distributed left and right, that is, distributed along the length direction of the steel box girder flange plate 1, so it is more convenient to move the positioning plate 2 laterally during the construction process.

[0039] like Figures 1 to 4 As shown, the welding mold further includes a positioning member, which is arranged on the positioning plate 2 and is used to position the positioning plate 2 on the surface of the steel box girder wing plate 1.

[0040] Specifically, it should be noted that the positioning member is used to position the positioning plate 2 on the surface of the steel box girder wing 1, so that the position of the positioning plate 2 is determined during the welding process of the shear nails, thereby ensuring the accuracy of the shear nails through the positioning holes 4. The positioning member here can be pin-positioned or slot-positioned, etc., as long as the positioning plate 2 can be fixed on the steel box girder wing 1.

[0041] like Figures 1 to 4 As shown, two positioning plates 2 are provided and are parallel to each other, and the two positioning plates 2 are respectively located on the two wing plates of the steel box girder.

[0042] Specifically, it should be noted that, since flanges are provided on both sides of the steel box girder, two positioning plates 2 can be provided so that shear nail welding can be performed on the flanges on both sides at the same time, thereby improving the shear nail welding efficiency.

[0043] like Figures 1 to 4 As shown, the two positioning plates 2 are symmetrically arranged and fixedly connected by a connecting member 3.

[0044] Specifically, it should be noted that the two positioning plates 2 are symmetrically arranged through the center line of the steel box girder surface, and the two positioning plates 2 are fixed by connecting parts 3, so that the relative positions of the two positioning plates 2 are determined, and the relative positions of the positioning holes 4 on the positioning plates 2 are determined, so that the two positioning plates 2 can be quickly installed on the steel box girder wing plates 1 at the same time, and the horizontal position and verticality of the shear nails on the two side wing plates are guaranteed.

[0045] like Figures 1 to 4 As shown, the connecting member 3 is configured as a steel cross-connection, and at least two steel cross-connections are configured.

[0046] Specifically, it should be noted that the two positioning plates 2 are fixedly connected by a steel cross-joint. The steel cross-joint and the positioning plates 2 can be connected by bolts. The steel cross-joint is easy to obtain at the construction site. The steel cross-joint is set to at least two, which can ensure the stability of the connection between the two positioning plates 2 and improve the structural strength.

[0047] like Figures 1 to 4 As shown, the positioning member includes a clamp arranged on the inner side of the positioning plate 2, and the lower end of the clamp extends out of the lower surface of the positioning plate 2. The clamp is set as a first clamp 6 and a second clamp 7. The first clamp 6 is perpendicular to the inner side surface of the positioning plate 2, and the second clamp 7 is parallel to the inner side surface of the positioning plate 2. The first clamp 6 is used to contact with the steel box girder cross diaphragm 5, and the second clamp 7 is used to contact with the side of the steel box girder flange 1.

[0048] Specifically, it should be noted that the positioning member is installed on the inner side of the positioning plate 2, that is, the opposite side of the two positioning plates 2, and the lower end of the clamp extends out of the lower surface of the positioning plate 2, so that the lower end of the clamp can act on the positioning point on the steel box girder to determine the position of the positioning plate 2, and the clamp is divided into a first clamp 6 and a second clamp 7. Since the first clamp 6 is perpendicular to the side of the positioning plate 2 and is used to contact the cross-diaphragm 5 of the steel box girder, the lateral position of the positioning plate 2 can be determined by the first clamp 6, and the second clamp 7 is parallel to the inner side of the positioning plate 2 and contacts the inner side of the steel box girder flange 1, so that the longitudinal position of the positioning plate 2 can be determined by the second clamp 7, that is, the lateral and longitudinal positions of the positioning plate 2 are determined by the first clamp 6 and the second clamp 7, and the positioning accuracy is high and the positioning is convenient.

[0049] like Figures 1 to 4As shown, the first clamp 6 and the second clamp 7 are both made of angle steel, a right-angled side of the first clamp 6 is fixedly connected to the inner side of the positioning plate 2, and the other right-angled side is used for abutment connection with the steel box girder cross diaphragm 5, a right-angled side of the second clamp 7 is fixedly connected to the inner side of the positioning plate 2, and the other right-angled side is fixedly connected to the connecting member 3.

[0050] Specifically, it should be noted that a right-angled side of the first clamp 6 is welded to the inner side surface of the positioning plate 2, and two right-angled sides of the second clamp 7 are respectively welded to the connecting member 3 and the inner side surface of the positioning plate 2. The second clamp 7 can simultaneously determine the verticality of the connecting member 3, thereby improving the use accuracy of the positioning plate 2.

[0051] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
