[0032] Please refer to Figure 1 The present embodiment provides a cap beam support system 100 for forming a cap beam 50, which includes a pier 10, a hoop 20, a sand cylinder 30 and an I-beam system 40. The pier 10 is used to support the cap beam formwork 51. The hoop 20 is sleeved on the pier 10 and fixed on the pier 10. A support platform 21 is provided on the top of the hoop 20. The sand cylinder 30 is located on the support platform 21. The sand cylinder 30 can adjust the top surface height of the sand cylinder 30 by adding or releasing sand. The I-beam system 40 is covered on the top of the sand cylinder 30 to support the cap beam formwork 51. The cap beam formwork 51 is used to cast and form the cap beam 50.

[0033] In this embodiment, one end of the pier column 10 is fixed on the ground, and the other end is used to support the cap beam template 51. When the construction is completed, the pier column 10 is also used to support the cap beam 50.

[0034] The hoop 20 includes two semicircular steel plates, which are fixed by bolts to form a circular hoop. A support platform 21 is provided on the top surface of the hoop 20, and the area of ​​the support platform 21 is larger than the cross-sectional area of ​​the pier 10. It can be understood that the bolt tension of the hoop 20 in this embodiment ensures that the friction between the hoop 20 and the pier 10 reliably transfers the load.

[0035] Optionally, in order to increase the friction between the hoop 20 and the pier 10 , the inner wall of the hoop 20 is provided with felt (not shown).

[0036] Further, the sand barrel 30 includes a barrel wall 31 and a sand core 32 disposed in the barrel wall 31. The sand core 32 can be adjusted by adding sand or releasing sand to adjust the top surface height of the sand core 32. Specifically, in this embodiment, the sand of the sand core 32 should not contain any impurities, such as stones, soil, etc.; the sand particles should be uniform in size, without too much fine sand or coarse sand; the sand should be kept dry to avoid excessive moisture and high humidity; the sand should be kept loose, without obvious caking or agglomeration.

[0037] Please refer to Figure 2 There are multiple sand cylinders 30, which are respectively located on both sides of the pier 10. Optionally, in this embodiment, two sand cylinders 30 are provided on each pier 10, one on each side of the pier 10, for supporting the I-beam system 40.

[0038] Please refer to Figure 1 and Figure 2 In this embodiment, the I-beam system 40 includes a transverse I-beam 41. The transverse I-beam 41 includes a first I-beam 411 and a second I-beam 412. The first I-beam 411 and the second I-beam 412 are both covered on the top of the sand cylinder 30. The first I-beam 411 and the second I-beam 412 are respectively located on both sides of the pier 10. It can be understood that the length direction of the transverse I-beam 41 is along the transverse direction of the bridge deck. It should be noted that the cap beam 50 in this embodiment is used to support the bridge deck, and the length direction of the cap beam 50 is consistent with the transverse direction of the bridge deck.

[0039] Furthermore, the first I-beam 411 and the second I-beam 412 are fixedly connected by a tie rod 413. The tie rod 413 pulls the first I-beam 411 and the second I-beam 412 against each other, so that the first I-beam 411 and the second I-beam 412 are stably placed on the sand cylinder 30, and also plays a role in stabilizing the sand cylinder 30 and preventing overturning.

[0040] Optionally, in order to ensure the integrity of the cap beam support system 100 , the first I-beam 411 and the second I-beam 412 are respectively fitted with the outer surface of the pier 10 . Further, the outer wall of the sand cylinder 30 is fitted with the outer surface of the pier 10 .

[0041] In this embodiment, in order to improve the strength of the cap beam support system 100, the I-beam system 40 further includes a longitudinal I-beam 42. The longitudinal I-beam 42 is located on the top of the transverse I-beam 41 and is fixedly connected to the first I-beam 411 and the second I-beam 412. The top surface of the longitudinal I-beam 42 is used to support the cap beam formwork 51.

[0042] Specifically, there are a plurality of longitudinal I-beams 42 , which are spaced apart above the transverse I-beams 41 .

[0043] The working principle and process of the cap beam support system 100 provided by the embodiment of the utility model are:

[0044] When the cap beam 50 is being formed, the hoop 20 is set on the completed pier 10, and the hoop 20 is tightened by bolts to increase the friction between the hoop 20 and the pier 10, so as to fix the hoop 20 to the pier 10. In this embodiment, the average height of the pier 10 is 7.5m, and the hoop 20 is installed at a position 80cm away from the top of the pier 10 through measurement.

[0045] After measuring the gravity of poured concrete and steel bars, the deadweight of formwork and I-beams, the loads of construction personnel, construction equipment and construction materials, and comparing the maximum load borne by a single sand barrel 30, the number of sand barrels 30 to be used is calculated. The sand barrel 30 is placed on the support platform 21 of the hoop 20. The transverse I-beam 41 is placed on the sand barrel 30 and fixed with a tie rod 413 to stabilize the sand barrel 30 and prevent it from overturning.

[0046] The bottom elevation of the cap beam template 51 should be 2 cm higher than the actual elevation to eliminate the sedimentation of sand in the sand tube 30. The top elevation of the sand tube 30 = the bottom elevation of the cap beam 50 + 2 cm - the bottom mold height - the height of the longitudinal I-beam 42 - the height of the transverse I-beam 41.

[0047] It is understandable that when the clamp 20 is not installed at the designated position or deviates from the designated position, the sand cylinder 30 can adjust the top surface height of the sand cylinder 30 by adding or releasing sand, thereby adjusting the bottom elevation of the cap beam 50, without removing the clamp 20 to adjust the position. When the cap beam 50 needs to be demolded, the sand in the sand cylinder 30 only needs to be released, and the bottom mold of the cap beam 50 will fall off while the I-beam system 40 falls.

[0048] The cap beam support system 100 provided by the embodiment of the utility model has the following beneficial effects:

[0049] The utility model includes a pier column 10, a hoop 20, a sand cylinder 30 and an I-beam system 40. The pier column 10 is used to support a cap beam formwork 51. The hoop 20 is sleeved on the pier column 10 and fixed on the pier column 10. A support platform 21 is provided on the top of the hoop 20. The sand cylinder 30 is located on the support platform 21. The sand cylinder 30 can adjust the top surface height of the sand cylinder 30 by adding sand or releasing sand. The I-beam system 40 is covered on the top of the sand cylinder 30 and is used to support the cap beam formwork 51. The utility model adds a sand cylinder 30 between the pier column 10 and the I-beam system 40, and the sand cylinder 30 can adjust the top surface height of the sand cylinder 30 by adding sand or releasing sand, thereby adjusting the bottom elevation of the cap beam 50. When the hoop 20 is not installed at the specified position or deviates from the specified position, there is no need to remove the hoop 20 to adjust the position, thereby improving construction efficiency. Furthermore, when demoulding, it is only necessary to release the sand in the sand cylinder 30 , and the bottom mold of the cap beam 50 will fall off while the I-beam system 40 falls, so that the cap beam 50 can be demoulded easily.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
