Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, and more specifically to a temporary supporting device for a cast-in-place beam. Background Art

[0002] Cast-in-place beams are a construction process that is usually used for large and medium-sized bridges. Because of the inconvenience of transportation, bridges are made on-site at the construction site. The method is to first tie up the steel skeleton to form a formwork, and then pour concrete. At present, the construction of cast-in-place beams of bridges mostly adopts the scaffolding method. The formwork of the scaffolding method is supported by evenly arranged steel columns. The adjacent steel columns are reinforced by support rods. After the construction of the cast-in-place beam is completed, the steel columns and support rods must be removed. However, the steel columns and support rods are fixed by welding. The technical requirements of welding are high. Welding and subsequent dismantling are both time-consuming and laborious, and the labor and material costs are high, which seriously affects the efficiency and cost of cast-in-place beam construction. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a temporary support device for cast-in-place beams, in which the support rods and steel columns are connected in an assembled manner, which is convenient for assembly and dismantling, improves construction efficiency and reduces construction costs.

[0005] The clamp comprises two clamps butted together, and the clamp comprises an intermediate plate tightly attached to the outer wall of the steel column and a first connecting plate and a second connecting plate respectively arranged on both sides of the intermediate plate, the width of the first connecting plate is greater than the width of the second connecting plate, connecting holes are arranged on the edges of the first connecting plate and the second connecting plate close to the intermediate plate, and a mounting hole is arranged on the edge of the first connecting plate away from the intermediate plate.

[0006] The connecting hole of the first connecting plate of the clamp is aligned with the corresponding connecting hole of the second connecting plate of the clamp and connected by bolts and nuts, and the end of the support rod is connected to the mounting hole by bolts and nuts.

[0007] The middle plate is an arc plate, and the first connecting plate and the second connecting plate are respectively arranged along two straight sides of the arc plate.

[0008] The angle of the arc plate is less than 180 degrees and greater than 150 degrees, and the inner diameter of the arc plate is equal to the outer diameter of the steel column.

[0009] The middle plate is a U-shaped plate, which includes a square plate and side plates vertically connected to both sides of the square plate, the spacing between the two side plates is equal to the width of the steel column, and the first connecting plate and the second connecting plate are respectively arranged along the edges of the corresponding side plates.

[0010] The width of the side plate is less than half of the width of the steel column.

[0011] The number of the connection holes is greater than 3, and the connection holes are arranged along the edge of the middle plate.

[0012] The number of the mounting holes is one, two or three, and the mounting holes are arranged along the edge of the first connecting plate away from the middle plate.
