In general, as shown in FIG. 1, one girder joint may be required to be installed at both ends of the stringer 10, and the girder joints at both ends of the stringer 10 may be different in structure and form, and thus, the present embodiment refers to girder joints at both ends of the stringer 10 by the first girder joint 9 and the second girder joint 11, respectively. It should be noted that the first girder joint 9 and the second girder joint 11 may be the same or different, and this is merely for distinguishing and facilitating the following description.
As shown in fig. 1 and 2, the installation and size assurance tool for girder joints and stringers according to the embodiment of the present utility model includes a platform 5, a second positioning support 2 and a third positioning support 7. For convenience of description, a space rectangular coordinate system shown in fig. 1 is introduced to illustrate a related structure of an embodiment of the present utility model, wherein a direction shown by an X axis is a rear direction, a direction shown by a Y axis is a left direction, and a direction shown by a Z axis is an upper direction.
The second positioning support 2 and the third positioning support 7 are mounted on the platform 5 at intervals along the length direction of the platform 5, and the second positioning support 2 and the third positioning support 7 are located on the same surface of the platform 5, such as the top surface. The second positioning support 2 and the third positioning support 7 are connected to the platform 5 by fasteners including, but not limited to, bolts or the like.
The second locating abutment 2 is used for locating and supporting the junction of the first girder joint 9 and the stringer 10. For example, the second locating abutment 2 is provided where the left end of the stringer 10 is connected to the right end of the first girder joint 9. And, some spacing grooves or spacing protrusions can be preset on the second positioning support 2 to adapt to the shapes of the ends of the first girder joint 9 and the stringer 10, so that the ends of the first girder joint 9 and the stringer 10 have unique assembly positions on the second positioning support 2 to ensure assembly accuracy.
Correspondingly, the third positioning support 7 is used for positioning and supporting the connection of the second girder connection 11 and the stringer 10. For example, the third positioning support 7 is provided where the right end of the stringer 10 is connected to the left end of the second girder joint 11. In addition, a plurality of limit grooves or limit protrusions can be preset on the third positioning support 7 to adapt to the shapes of the second girder joint 11 and the end part of the stringer 10, so that the second girder joint 11 and the end part of the stringer 10 have a unique assembly position on the third positioning support 7 to ensure the assembly precision.
The second positioning support 2 and the third positioning support 7 are matched, so that the stringer 10 and the girder joint can be rapidly positioned and assembled, the position and the size of the stringer 10 and the girder joint after being assembled can be guaranteed by the second positioning support 2 and the third positioning support 7, and the conditions of deformation, dislocation, size deviation, short or the like can not occur after the assembly; and the contact surface of the stringer 10 and the girder joint can be completely fitted, no gaps can occur any more so as to prevent the entry of surplus substances.
In some embodiments, at least one first jig 3 may also be mounted on the platform 5. The first jig 3 is located at the connection of the first girder joint 9 and the stringer 10, and the first jig 3 is used for positioning a connection through hole at the connection of the first girder joint 9 and the stringer 10. In general, the stringer 10 and the girder joint are accurately positioned by plugging, and after plugging in place, holes are needed to be formed at the joint of the stringer 10 and the girder joint so as to add firm pieces such as bolts and the like to realize firm connection of the stringer 10 and the girder joint. According to the embodiment of the utility model, the first drilling jig 3 is arranged on the platform 5 to realize the positioning of the connecting through hole at the joint of the first girder joint 9 and the stringer 10, and then a cutter or a drilling, reaming tool and the like can be guided to pass through the first drilling jig 3 to process a required hole at the joint of the first girder joint 9 and the stringer 10, and the type of the first drilling jig 3 can be replaced at any time according to the drilling, reaming and reaming requirements. The first jig 3 ensures the position of the opening, so that the connection precision of the stringer 10 and the girder joint is easier to control, and the situation that the dislocation, the size deviation or the deviation and the like are beyond design when the stringer 10 and the girder joint are connected is avoided.
The first drilling jig 3 can be respectively arranged at the two sides of the joint of the first girder joint 9 and the stringer 10 to improve the perforating efficiency, and perforating can be simultaneously carried out at the two sides, but under the condition that certain perforating depths are deeper and the perforating can not be completed at one side at one time, the drilling jig can be further rotated to the other side to continue perforating after the perforating work with a certain depth is completed at one side, and the first drilling jig 3 is not required to be moved.
Similarly, in the embodiment of the present utility model, at least one second jig 6 may be further installed on the platform 5 corresponding to the connection between the second girder joint 11 and the stringer 10 for positioning the connection through hole at the connection between the second girder joint 11 and the stringer 10, or even one second jig 6 may be installed on each of two sides of the connection between the second girder joint 11 and the stringer 10. The second drill jig 6 functions similarly to the first drill jig 3 and will not be described again here for the sake of economy.
In order to achieve positioning and support of the stringers 10, embodiments of the utility model may also mount at least one support foot 4 on the platform 5. Since the stringers 10 are located between the first and second girder joints 9, 11, the support seat 4 is also located between the second and third locating seats 2, 7. The support seat 4 may be provided with grooves or projections according to the shape of the stringer 10 to adapt as closely as possible to the contact surface of the stringer 10 so that the stringer 10 has a single support limit on the support seat 4. Meanwhile, as the stringer 10 may be longer, the support of the stringer 10 by the support seat 4 also ensures that the stringer 10 cannot be easily deformed in the assembly process, and finally ensures the dimensional accuracy after assembly. When the support seats 4 are provided with more than two support seats, the support seats 4 are arranged at intervals along the length direction of the platform 5 and are uniformly distributed, so as to provide a more uniform support effect for the stringers 10.
To further ensure dimensional accuracy of the stringer 10 during assembly, embodiments of the present utility model may further comprise at least one clamp plate 8, the clamp plate 8 being detachably connected to the platform 5 by fasteners including, but not limited to, bolts, the clamp plate 8 being adapted to compress the stringer 10 onto the support base 4. Since the bolts are required to be connected between the stringers 10 and the girder joints, in order to avoid the stringers 10 moving during operation, the embodiment of the present utility model can press the stringers 10 to the support base 4 by the press plate 8, so that dimensional errors caused by the movement of the stringers 10 can not occur any more during the connection of the bolts, even during the perforation of the stringers 10 and the girder joints using the first jig 3 and the second jig 6. When the pressure plate 8 is provided with more than two pressure plates, the pressure plates 8 are arranged at intervals along the length direction of the platform 5 so as to provide better compression effect on the stringers 10.
If the size of a certain girder joint is too large, a positioning support can be additionally arranged on the platform 5 when effective support cannot be realized by only one positioning support. For example, when the first girder joint 9 is the case, a first positioning support 1 may be installed on the platform 5 at a side of the second positioning support 2 remote from the third positioning support 7, the first positioning support 1 being used for positioning and supporting the first girder joint 9. Since the first girder erection joint 9 and the second girder erection joint 11 are relatively, the positioning support additionally installed can also be used for positioning and supporting the second girder erection joint 11.
The embodiment of the utility model is used in the following manner:
and placing the first girder joint 9 and the second girder joint 11 on the tool, and tightly attaching the surfaces of the first girder joint 9 and the second girder joint 11 to the limiting support surfaces of the second positioning support 2 and the third positioning support 7. The first girder joint 9 and the second girder joint 11 are provided with preset through holes, the second positioning support 2 and the third positioning support 7 are also provided with preset positioning holes, and the first girder joint 9 and the second girder joint 11 can be tightly attached to the second positioning support 2 and the third positioning support 7 after the fasteners such as bolts, gaskets, nuts and the like pass through the corresponding holes. The stringer 10 is then installed between the first and second girder joints 9 and 11 and placed on the support base 4, and the pressure plate 8 is pressed against the stringer 10 to prevent loosening of the stringer 10. Finally, the first drilling jig 3 and the second drilling jig 6 are assembled according to the requirement, the drilling jigs are sequentially replaced according to the sequence of drilling, reaming and reaming, hole machining is carried out, surplus materials are cleaned, bolts, gaskets and nuts are installed and screwed down, and therefore the accurate assembly of the first girder joint 9, the second girder joint 11 and the stringers 10 is completed.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
