[0002] This utility model relates to concrete pouring formwork in the field of building construction, and in particular to a support structure for constructing upper beam pouring formwork based on lower beams. Background Technology

[0003] In the construction of large-scale buildings with frame structures in the existing technology, when pouring multi-layer concrete beams, the height distance between adjacent beams can be more than ten meters, and the beams need to be poured layer by layer. The construction of the beam pouring formwork requires ensuring the relative parallel position error, dimensional error, stability of the formwork support, and the ability to withstand certain external pouring forces, especially ensuring the parallel position error and the stability of the formwork support.

[0004] In existing technologies, the re-casting of beam formwork involves erecting scaffolding to support the formwork. The disadvantages of this technology are: high cost, difficulty in adjusting the formwork support, potential for positional errors, and poor stability of the formwork support. Utility Model Content

[0005] To address the drawbacks of using scaffolding to support the formwork during the re-casting of beams, such as high costs, difficulty in adjusting formwork supports, potential for positional errors, and poor stability, this utility model discloses a support structure for constructing upper beam formwork based on a lower beam.

[0006] The technical solution adopted by this utility model to achieve the purpose of the invention is: a support structure for building an upper beam casting template based on a lower beam. The support structure includes: a beam template, a support back plate and a back plate support rod. The beam template is fixed as a whole by the back plate tie rod bolts through the support back plate. The back plate support rods form a support structure for the support back plate.

[0007] The support structure further includes: a diagonal brace support section and a diagonal brace section.

[0008] The inclined tie rod support includes: a horizontal support beam, an inclined support rod, and an inclined support rod connecting seat. The horizontal support beam is set on the cast-in-place crossbeam, and the back plate support rod is set on the horizontal support beam. Both ends of the inclined support rod are rotatably connected to the inclined support rod connecting seat. The inclined support rod connecting seat at one end of the inclined support rod is fixedly connected to the side of the cast-in-place crossbeam, and the inclined support rod connecting seat at the other end of the inclined support rod is fixedly connected to the horizontal support beam with an adjustable relative connection position.

[0009] The diagonal brace section includes: a back plate diagonal brace, a back plate diagonal brace connecting seat, a support diagonal brace, and a support diagonal brace connecting seat, all arranged in symmetrical pairs. The two ends of the back plate diagonal brace are rotatably connected to the back plate diagonal brace connecting seat, and the two ends of the support diagonal brace are rotatably connected to the support diagonal brace connecting seat.

[0010] The back plate diagonal bracing rod connecting seat at one end of the symmetrically paired back plate diagonal bracing rod is fixedly connected to the crossbeam template and the supporting back plate by template bolts and tie rods. The back plate diagonal bracing rod connecting seat at the other end of the back plate diagonal bracing rod forms a fixed connection with the horizontal support beam with an adjustable relative connection position.

[0011] The symmetrically paired support diagonal braces have their support diagonal brace connecting seats at one end fixedly connected to the back plate support rod by support rod bolts and tie rods. The support diagonal brace connecting seats at the other end of the support diagonal braces form a fixed connection with the horizontal support beam with adjustable relative connection position.

[0012] The beneficial effects of this utility model are: the formwork for recasting the beam is built based on the already cast beam, which is simple in structure, saves materials, is easy to adjust, has high accuracy in position, and has low support height and good stability.

[0019] See the attached diagram. A support structure for constructing an upper beam casting template based on a lower beam is provided. This support structure includes: a beam template 4, a support back plate 5, and back plate support rods 8. The beam template 4 is fixed to the support back plate 5 as a single unit by tie rod bolts. The back plate support rods 8 form a support structure for the support back plate 5.

[0020] The template support structure also includes: a diagonal brace support section and a diagonal brace section;

[0021] The inclined tie rod support includes: a horizontal support beam 1-1, an inclined support rod 1-2, and an inclined support rod connecting seat 1-3. The horizontal support beam 1-1 is mounted on the cast-in-place crossbeam 2, and the back plate support rod 8 is mounted on the horizontal support beam 1-1. The two ends of the inclined support rod 1-2 are rotatably connected to the inclined support rod connecting seat 1-3. The inclined support rod connecting seat 1-3 at one end of the inclined support rod 1-2 is fixedly connected to the side of the cast-in-place crossbeam 2, and the inclined support rod connecting seat 1-3 at the other end of the inclined support rod 1-2 is fixedly connected to the horizontal support beam 1-1 with an adjustable relative connection position.

[0022] The diagonal brace section includes: a back plate diagonal brace 3-1, a back plate diagonal brace connecting seat 3-2, a support diagonal brace 3-3, and a support diagonal brace connecting seat 3-4, which are arranged in symmetrical pairs. The two ends of the back plate diagonal brace 3-1 are rotatably connected to the back plate diagonal brace connecting seat 3-2, and the two ends of the support diagonal brace 3-3 are rotatably connected to the support diagonal brace connecting seat 3-4.

[0023] The back plate diagonal bracing rod 3-1 is symmetrically paired.
