Description

Technical Field

[0001] The utility model relates to the technical field of bridge support construction, in particular to an anchored water diversion aqueduct template steel support device. Background Art

[0002] In traditional aqueduct construction, the formwork support system for the trough body typically utilizes floor-standing steel pipe supports. Before the supports are erected, the foundation must be reinforced with concrete and drainage ditches must be installed around the supports. This support system consumes a large amount of concrete and earthwork, and is susceptible to flooding during the rainy season. Furthermore, during arch aqueduct construction, if floor-standing supports are used for the trough body formwork located above the arch ribs, the trough body is relatively tall, resulting in a lengthy and slow erection process and significant consumption of manpower and equipment resources. Furthermore, due to the overlapping space between the arch ribs and the trough body, the supports cannot be erected in certain areas. Consequently, floor-standing supports have poor on-site applicability and low stability and safety. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-6 As shown, an anchored water diversion aqueduct template steel support support device includes a cap beam 1, and anchoring legs 2 are respectively provided on opposite sides of the cap beam 1. Through-core steel rods 3 and fine-rolled threaded steel bars 4 are passed through the cap beam 1 and the anchoring legs 2. The through-core steel rods 3 and the fine-rolled threaded steel bars 4 are set at the same elevation, which not only limits the movement of the anchoring legs to the greatest extent, but also makes the characteristic values such as the moment of inertia and section resistance moment of the anchoring legs force transmission steel plate reach the optimal value, thereby ensuring the bearing capacity of the anchoring legs. The surface of the cap beam 1 is provided with through-core steel rod reserved holes 11 and fine-rolled threaded steel reserved holes 12, and the anchoring legs 2 are provided with through-core steel rod mounting holes 21 and fine-rolled threaded steel mounting holes 22. The through-core steel rod 3 is passed through the through-core steel The reserved holes 11 for the rods and the mounting holes 21 for the through-steel rods, and the spacing between the through-steel rods 3 and the high-quality rolled threaded steel bars 4 are 110-130mm, which increases the strength of the force transmission section of the anchoring corbel and minimizes the risk of self-instability. The high-quality rolled threaded steel bars 4 are passed through the reserved holes 12 for the high-quality rolled threaded steel bars and the mounting holes 22 for the high-quality rolled threaded steel bars. Steel gaskets 5 are set at both ends of the high-quality rolled threaded steel bars 4 to fit tightly with the anchoring corbels 2 and are firmly fixed by nuts 6, so that the anchoring corbels 2 fit tightly with the cap beam. Sand boxes 7 are horizontally arranged above the multiple anchoring corbels 2. The bottom mold elevation can be adjusted by adjusting the sand boxes 7. I25a double-piece I-beams 8 are installed in the transverse bridge direction above the multiple sand boxes 7, and multiple I25 I-beams 9 are installed in the longitudinal groove direction above the I25a double-piece I-beams 8.

[0021] The reserved hole 21 for the through-steel rod in the cap beam is set as a steel pipe, and the inner diameter is 10-13mm larger than the diameter of the through-steel rod 3. The reserved hole 12 for the high-quality rolled threaded steel in the cap beam is a circular hole, and the aperture of the reserved hole 12 for the high-quality rolled threaded steel in the cap beam is 8-10mm larger than the diameter of the high-quality rolled threaded steel 4. A certain gap is reserved for easy installation. The through-steel rod 3 is made of an alloy material with 40cr or more, and the steel plate material of the anchoring corbel 2 is Q235B. The materials of the I25a double-piece I-beam 8 and the I25 I-beam 9 are both Q235B. The above design ensures that the material strength required to meet the bearing capacity is met.

[0022] Working principle: During the construction of the cap beam, installation holes are reserved. During the construction of the bracket, the through steel rod 3 and the high-precision rolled threaded steel bar 4 are inserted into the reserved opening of the cap beam. Two anchoring corbels 2 are set as a group, one on each side of the cap beam 1. The number of groups is determined according to the size of the cap beam and the calculated load. The anchoring corbel 2 is put on the through steel rod 3 and the high-precision rolled threaded steel bar 4. Steel gaskets 5 are set at both ends of the high-precision rolled threaded steel bar 4 to fit tightly with the anchoring corbel 2 and are firmly fixed by nuts 6, so that the anchoring corbel is close to the cap beam 1 to prevent the anchoring corbel 2 from moving outward. Then set up the sand box 7 and repeat the above steps in sequence. After the installation is completed in the same span, the longitudinal and transverse beams and I-beams are set in sequence. When dismantling the device, from top to bottom, symmetrically, set up the I25 I-beam longitudinal beam 9, the I25a double-piece I-beam 8, and the sand box 7 in sequence. After the nut 6 is removed, the anchoring corbel 2 is lifted off, and then the through steel rod 3 and the high-precision rolled threaded steel bar 4 are removed, and the reserved holes of the cap beam are filled and repaired to complete the construction.
