Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a beam formwork support for a beam and slab node of a bent formwork support system. Background Art
[0002] Please refer to Figure 1 , in the bent formwork support system, for the beam formwork support at the beam and slab node, generally, the top horizontal steel pipe of the bent formwork support system is tightly pressed against the upper part of the lateral formwork of the corresponding side beam formwork, that is, the top horizontal steel pipe serves as both the formwork support rod 10 of the slab formwork and the support rod of the lateral formwork of the beam formwork. A plurality of tension bolts 16 are arranged and connected between the two lateral formworks of the beam formwork. The bottom formwork of the beam formwork is supported by the bottom horizontal steel pipe of the horizontal bent formwork support system. At this time, the bottom horizontal steel pipe serves as the beam support rod 1. Side vertical steel pipes 2 are arranged on both sides of the lateral formwork of the beam formwork. The intersection points of the side vertical steel pipes 2 with the formwork support rod 10 and the beam support rod 1 are connected by pipe fasteners (not shown). The cross-section of the beam formwork is U-shaped, and the bent formwork support system is a disc buckle type scaffolding or a fastener type scaffolding. Since the formwork support rod 10 of the beam formwork is tightly pressed against the lateral formwork of the beam formwork, the cantilever of the formwork support rod 10 at the beam and slab node is too large, which affects the load transfer force on the beam side support 6 and the vertical pole 5. In addition, at the node of the formwork support rod 10 and the side vertical steel pipe 2 at the beam formwork node, it is difficult to connect and fix by pipe fasteners due to the narrow working space, which affects the structural force on the side of the beam formwork. At the intersection point of the beam support rod 1 and the support 6 at the bottom of the beam, since the beam support rod 1 is a round steel pipe and the threaded rod of the support 6, it is difficult to connect and fix at the intersection point, which affects the structural force at the bottom of the beam formwork, resulting in poor concrete forming quality at the beam formwork. In addition, when connecting by the tension bolt 16 at the beam formwork, it is necessary to punch holes between the two lateral formworks of the beam formwork and subsequent plugging is required. Limited by the operation space at the beam and slab node, it is not convenient for plugging construction, and the tension bolts 16 distributed longitudinally on the beam formwork increase the cost. In addition, when the dimensions such as the height and width of the beam formwork change, it is difficult to adjust the connection between the formwork support rod 10, the beam support rod 1, the side vertical steel pipe 2 and the bent formwork support system, resulting in poor versatility of the existing beam formwork support. Especially, when the distance between the beam side vertical pole and the beam edge is too small, the construction is inconvenient; when the distance between the beam side vertical pole and the beam edge is too large, it affects the beam side load transfer. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a beam formwork support for a beam and slab node of a bent formwork support system to solve the problems that when the formwork support rod is tightly pressed against the lateral formwork of the beam formwork, there is a large cantilever resulting in poor structural force, the working space at the intersection nodes of the beam support rod, the side vertical steel pipe, the formwork support rod and the vertical pole or the top plate is small and it is impossible to connect by pipe fasteners or inconvenient to connect by pipe fasteners, and the use of tension bolts for the beam formwork results in high cost and complicated subsequent construction.
