[0029] As Figures 1 - 3 shown, this embodiment provides a temporary fixing structure for the construction of a tower-beam through structure. The main beam 1 and the main tower 2 are both arranged on the lower tower pier 3, and the main tower 2 vertically penetrates the main beam 1. Transverse temporary consolidation systems 4 are arranged between both longitudinal sides of the main tower 2 and the main beam 1, and longitudinal temporary consolidation systems 5 are arranged between both transverse sides of the main tower 2 and the main beam 1. The transverse temporary consolidation systems 4 and the longitudinal temporary consolidation systems 5 are both arranged in the horizontal direction. This embodiment utilizes the characteristics of the tower-beam through structure itself to horizontally arrange the temporary consolidation systems, effectively solving the problem of the tight temporary consolidation space of the tower-beam through structure; and separating the longitudinal and transverse consolidations to avoid the unfavorable stress conditions under the combined action of bending, shear, and torsion in the traditional vertical consolidation.

[0030] In some embodiments, the transverse temporary consolidation system 4 includes a transverse limiting block 41 and a transverse block cushion stone 42. One end of the transverse block cushion stone 42 abuts against the main tower 2, and the transverse limiting block 41 is arranged between the other end and the main beam 1. This embodiment realizes the effective fixation and limitation of the main tower 2 and the main beam 1 in the transverse direction through the combined use of the transverse limiting block 41 and the transverse block cushion stone 42.

[0031] Optimally, first bituminous felt isolation layers are arranged on both end faces of the transverse limiting block 41. In this embodiment, first bituminous felt isolation layers are arranged on the end face for abutting against one end of the main beam 1 and on the end face for abutting against one end of the transverse block cushion stone 42 of the transverse limiting block 41, which is beneficial for removing the transverse limiting block 41 and reducing friction and wear at the same time.

[0032] Further optimally, a first sulfuric acid mortar layer is arranged between at least one end face of the transverse limiting block 41 and the corresponding first bituminous felt isolation layer. In this embodiment, the first sulfuric acid mortar layer can be arranged only between the end face for abutting against one end of the main beam 1 of the transverse limiting block 41 and the first bituminous felt isolation layer thereon, or only between the end face for abutting against one end of the transverse block cushion stone 42 of the transverse limiting block 41 and the first bituminous felt isolation layer thereon, or the first sulfuric acid mortar layer can be arranged between both end faces of the transverse limiting block 41 and the first bituminous felt isolation layers on both end faces. The first sulfuric acid mortar layer can be removed relatively conveniently through methods such as high-temperature melting, so as to facilitate the removal of the transverse temporary consolidation system 4.

[0033] In this embodiment, the lateral limiting block 41 is a concrete block, and the sulfur cement mortar used for the first sulfur cement mortar layer is required to reach the M40 grade to ensure the strength requirement of the lateral temporary consolidation system 4.

In this embodiment, through the combined use of the longitudinal limiting block 51 and the longitudinal block cushion stone 52, the effective fixation and limitation of the main tower 2 and the main girder 1 in the longitudinal direction of the bridge are realized.

[0035] Optimally, second felt isolation layers are arranged on the end faces at both ends of the longitudinal limiting block 51. In this embodiment, second felt isolation layers are arranged on the end face for abutting against one end of the main girder 1 and the end face for abutting against one end of the longitudinal block cushion stone 52 of the longitudinal limiting block 51, so as to facilitate the removal of the longitudinal limiting block 51 and reduce friction and wear at the same time.

[0036] Further optimally, a second sulfur cement mortar layer is arranged between the end face of at least one end of the longitudinal limiting block 51 and the corresponding second felt isolation layer. In this embodiment, the second sulfur cement mortar layer can be arranged only between the end face for abutting against one end of the main girder 1 of the longitudinal limiting block 51 and the second felt isolation layer thereon, or only between the end face for abutting against one end of the longitudinal block cushion stone 52 of the longitudinal limiting block 51 and the second felt isolation layer thereon, or the second sulfur cement mortar layer can be arranged between the end faces at both ends of the longitudinal limiting block 51 and the second felt isolation layers at both end faces. The second sulfur cement mortar layer can be removed more conveniently by means of high-temperature melting, etc., so as to facilitate the removal of the longitudinal temporary consolidation system 5.

[0037] In this embodiment, the longitudinal limiting block 51 is a concrete block, and the sulfur cement mortar used for the second sulfur cement mortar layer is required to reach the M40 grade to ensure the strength requirement of the longitudinal temporary consolidation system 5. Further, the thickness of the second sulfur cement mortar layer is 5-15 cm; preferably, the thickness of the second sulfur cement mortar layer is 10 cm.

[0038] Such as Figure 2 and Figure 3As shown, the main beam 1 includes a main beam 1 top plate, a middle main beam 12, a side main beam 13 and a cross beam 14; the main tower 2 vertically penetrates the main beam 1 top plate from the space surrounded by the two middle main beams 12 and the two cross beams 14; the transverse temporary consolidation system 4 is arranged between the main tower 2 and the middle main beam 12, and the longitudinal temporary consolidation system 5 is arranged between the main tower 2 and the cross beam 14.

[0039] Among them, the middle main beam 12 and the side main beam 13 are arranged along the longitudinal bridge direction, and the two at the two ends of the transverse bridge direction are the side main beams 13, and the two in the middle are the middle main beams 12; the two middle main beams 12 are arranged on the lower tower pier 3 through a support system; the cross beam 14 is arranged along the transverse bridge direction, and there are multiple cross beams 14; the top plate of the main beam 1 is arranged on the top of the middle main beam 12, the side main beam 13 and the cross beam 14, and the top plate of the main beam 1 is provided with a through hole for the main tower 2 to pass through, and the through hole is provided with cross beams 14 on both sides of the transverse bridge direction, and the middle main beams 12 are provided on both sides of the longitudinal bridge direction; longitudinal temporary consolidation systems 5 are provided between the two sides of the transverse bridge direction of the main tower 2 and the cross beams 14 on both sides, and transverse temporary consolidation systems 4 are provided between the two sides of the longitudinal bridge direction of the main tower 2 and the middle main beams 12 on both sides.

[0040] In one embodiment, the main tower 2 includes an upper tower column and two lower tower columns 21 arranged along the longitudinal bridge direction, and the tops of the two lower tower columns 21 are fixed to the bottom of the upper tower column, and the bottoms of the two lower tower columns 21 are arranged on the lower tower pier 3; a transverse temporary consolidation system 4 is arranged between the two sides of the longitudinal bridge direction of each lower tower column 21 and the main beam 1; a longitudinal temporary consolidation system 5 is arranged between the opposite ends of the two lower tower columns 21 and the main beam 1.

[0041] like Figure 1 and Figure 2 As shown, two through holes for two lower tower columns 21 to pass through are arranged on the top plate of the main beam 1, and the bottoms of the two lower tower columns 21 pass through the two through holes respectively and are arranged on the lower tower pier 3; and a transverse temporary consolidation system 4 is arranged between the two sides of the longitudinal bridge direction of each lower tower column 21 and the middle main beams 12 on both sides, and two longitudinal temporary consolidation systems 5 are arranged between the side of each lower tower column 21 away from the other lower tower column 21 and the corresponding cross beam 14.

[0042] The working principle of the temporary fixed structure used for the tower-beam interpenetrating structure construction of this embodiment is as follows:

[0043] like Figure 4 As shown, when there is an unbalanced bending moment M in the longitudinal direction of the bridge during construction, the longitudinal temporary consolidation system 5 comes into play. Under the action of the unbalanced bending moment M, an axial force F sufficient to balance M is generated in the longitudinal temporary consolidation system 5. At this time, the temporary consolidation system is mainly under pressure.

[0044] like Figure 5As shown in the figure, when there is a transverse unbalanced bending moment M during the construction process, the transverse temporary consolidation system 4 comes into play at this time. Under the action of the unbalanced bending moment M, an axial force F sufficient to balance M is generated in the transverse temporary consolidation system 4. At this time, the temporary consolidation system is mainly under pressure.

[0045] As Figure 6 shown in the figure, when there is an unbalanced torque Mz in the horizontal plane during the construction process, the longitudinal temporary consolidation system 5 and the transverse temporary consolidation system 4 come into play simultaneously at this time. Under the action of the unbalanced torque Mz, an axial force F sufficient to balance Mz is generated in the longitudinal temporary consolidation system 5 and the transverse temporary consolidation system 4. At this time, the temporary consolidation system is mainly under pressure.

[0046] The compressive strength of concrete is much higher than its tensile strength. By using the temporary consolidation system to be under pressure to balance the bending moment and torque, it is possible to avoid the structural complexity caused by the vertical temporary consolidation being under tension to balance the bending moment and torque, and give full play to the advantage of the strong compressive capacity of the concrete material. Moreover, the temporary consolidation structure of this embodiment is simple in structure, convenient to install and operate, and has a low cost.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
