[0002] With the development of bridge engineering, the construction of large-span continuous beams is becoming more and more widespread. Currently, the commonly used bridge construction methods include cantilever casting or cantilever assembly. Although this cantilever construction method is quick and convenient, it also has the problem of bridge deck overturning caused by uneven cantilever weight.

[0003] To solve this problem, the commonly used solution is to set up temporary column brackets next to the pier or take temporary consolidation measures on the top of the pier:

[0004] The solution of setting up temporary columns next to the pier is costly, difficult to remove and has a long construction period, so this solution is rarely adopted now;

[0005] The solution generally adopted for temporary consolidation measures on the top of the pier is to set up an embedded temporary consolidation support on the top of the pier. However, setting up this type of support also has disadvantages such as a long construction period and difficulty in removal.

[0006] The technical problem to be solved by this application is to design a temporary consolidation device for piers and beams that is simple to construct and can save materials. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: a pier-beam temporary consolidation device, comprising an upper anchor beam 2 fixedly mounted on a steel box beam 1, a lower anchor bracket 4 fixedly mounted on a pier column 3, and a temporary pier 5 arranged on the top of the pier column 3, a stiffening plate 7 is pre-buried inside the pier column 3, and the lower anchor bracket 4 is fixedly connected to the stiffening plate 7. When the temporary pier 5 is arranged on the top of the pier column 3, the upper end of the temporary pier 5 abuts against the lower surface of the upper anchor beam 2, thereby supporting the upper anchor beam 2 and the steel box beam 1 located at the upper end of the upper anchor beam 2. When the upper anchor beam 2 is installed at the bottom of the steel box beam 1, the temporary bracket end is installed at the top of the pier column 3 and the upper surface abuts against the upper anchor beam 2, and then the steel rod 6 is used to pass through the upper anchor beam 2 and the lower anchor bracket 4 respectively, the steel rod Double nut pads 8 are provided at both ends of 6, and finally the double nut pads 8 are used to lock and fix the two ends of the steel rod 6 with the upper anchor beam 2 and the lower anchor corbel 4 respectively, so that the installation of the entire pier-beam temporary consolidation device can be completed. The entire installation process is simple and easy to operate, which can greatly improve the construction efficiency. The upper anchor beam 2 is installed at the lower end of the steel box girder 1, and a temporary pier 5 is provided on the top of the pier column 3, and a fixed lower anchor corbel 4 is also provided on the side of the pier column 3. Finally, the steel rod 6 is locked and fixed with the upper anchor beam 2 and the lower anchor corbel 4 respectively. In this way, even if the steel box girder 1 is subjected to an overturning force, the steel rod 6 will generate tension, thereby forming an anti-overturning moment with the temporary pier 5, thereby preventing the steel box girder 1 from overturning and collapsing.

[0026] The upper anchor beam 2 includes an upper top plate 20 and a lower bottom plate 21, and a plurality of webs 22 are provided between the upper top plate 20 and the lower bottom plate 21, which are respectively connected to the upper top plate 20 and the lower bottom plate 21. The upper anchor beam 2 is anchored to the steel box girder 1 by anchoring the upper top plate 20. Corresponding connecting holes 23 are also provided between the upper top plate 20 and the lower bottom plate 21. The steel rod 6 is limitedly matched with the upper anchor beam 2 by passing through the connecting hole 23. When this end of the steel rod 6 passes through the connecting hole 23 and is limitedly matched with the upper anchor beam 2, the double nut pad 8 can be used to lock and fix the steel rod 6 to the upper anchor beam 2.

[0027] The lower anchoring corbel 4 comprises an upper steel plate 40 and a lower steel plate 41, a plurality of connecting plates 42 respectively connected to the upper steel plate 40 and the lower steel plate 41 are arranged between the upper steel plate 40 and the lower steel plate 41, a web plate 22 is arranged between the upper top plate 20 and the lower bottom plate 21, and a connecting plate 42 is arranged between the upper steel plate 40 and the lower steel plate 41, so that the rigidity strength of the upper anchoring beam 2 and the lower anchoring corbel 4 can be improved, mainly by fixing the side of the connecting plate 42 with the stiffening plate 7 embedded in the pier column 3 so that the lower anchoring corbel 4 is fixedly connected to the stiffening plate 7, and the upper steel plate 40 is fixedly connected to the lower steel plate 40. There are also corresponding through holes 43 between the lower steel plate 41. The lower end of the steel rod 6 is mainly limited by the through hole 43 to cooperate with the lower anchoring corbel 4. When the lower end of the steel rod 6 passes through the lower anchoring corbel 4 and then is locked with the double nut pad 8, the connection between the steel rod 6 and the lower anchoring corbel 4 can be completed. Since the steel rod 6 and the upper anchoring beam 2 and the lower anchoring corbel 4 are fixed by the double nut pad 8, the steel rod 6 and the upper anchoring beam 2 and the lower anchoring corbel 4 are easy to remove and can be reused, thereby saving corresponding material costs.

[0028] The temporary pier 5 includes an upper end plate 50 and a lower end plate 51. A plurality of support plates 52 are arranged between the upper end plate 50 and the lower end plate 51, which are respectively connected to the upper end plate 50 and the lower end plate 51. The upper surface of the upper end plate 50 is inclined, and the slope of the upper surface of the upper end plate 50 in the transverse direction is consistent with the slope of the steel box girder 1. By making the slope of the upper surface of the upper end plate 50 in the transverse direction consistent with the slope of the steel box girder 1, the temporary pier 5 can better form an anti-overturning moment to prevent the bridge from overturning and damage. Since the overturning moments of the bridge in the longitudinal direction and the transverse direction are different, when it is necessary to select the size of the steel rod 6, the longitudinal direction, transverse direction and composite overturning moment of the bridge should be calculated separately. For example, according to the position of the steel rod 6 and the temporary pier 5, the force L of the tensile force of the steel rod 6 can be obtained. The force on each steel rod 6 in the longitudinal direction can be obtained by the formula

[0029]

[0030] The calculation shows that the most unfavorable position is the edge of the transverse bridge. Let its force arm be y1, and the maximum tension it receives can be expressed by the formula:

[0031]

[0032] Calculate and convert F x By superimposing it with F1, we can get the magnitude of the tension on the steel rod 6 at the most unfavorable position under the composite overturning moment, and then select the corresponding diameter of the steel rod 6 based on the calculated magnitude of the tension.

[0033] The working principle or beneficial effect of the utility model is as follows: by fixing the upper anchor beam 2 and the steel box beam 1, and providing a fixedly installed lower anchor corbel 4 on the side of the pier column 3, and also providing a temporary pier 5 at the upper end of the pier column 3, and then using the two ends of the steel rod 6 to pass through the upper anchor beam 2 and the steel box beam 1 respectively and connect them to each other, the installation of the entire pier-beam temporary consolidation device can be completed, and the whole installation process is simple and convenient. After the installation is completed, when the steel box beam 1 is subjected to an overturning force, the steel rod 6 will generate a tensile force, and then form an anti-overturning moment with the corresponding temporary pier 5, thereby preventing the steel box beam 1 from overturning and collapsing. Because the steel rod 6 is detachably connected to the upper anchor beam 2 and the steel box beam 1, it can be easily dismantled and can be repeatedly used, thereby saving the corresponding material cost.
