Embodiment Construction

[0010] The specific implementation will be described in detail below in conjunction with the accompanying drawings: Figure 1 ~ Figure 2 One embodiment of the invention is shown. In the figure, a reinforcement fixture for the ventral formwork of a stiffened concrete beam includes: several fixture units, the fixture unit consists of a left side rod 1, a right side rod 2, a pull screw 3 and a nut 4, and a limit sleeve rod 5 composition. One side rod ends of the left side rod 1 and the right side rod 2 are provided with grooves 6, and there are several equally spaced pull screw rods from the middle section of the left side rod 1 and the right side rod 2 to the other side of the rod section. The holes 7 through which the left side bar 1 and the right side bar 3 are grooved are attached to the ventral formwork 8 of the stiffened concrete beam, and the middle section and the tail section of the left side bar 1 and the right side bar 2 Each pair is provided with a pull screw 3, and...

Abstract

The invention relates to a fastening clamp for a web side formwork of a stiffened concrete beam. The fastening clamp comprises a plurality of clamp units, wherein each clamp unit consists of a left / right side rod, split bolts, nuts and stop collar rods, grooves are formed in the rod ends of one sides of the left / right side rods, a plurality of holes for threading the split bolts are formed from the middle sections of the left / right side rods to the rod sections on the other sides at an equal interval, the groove rod sections of the left / right side rods are attached to the web side formwork of the stiffened concrete beam, the split bolts are threaded through the middle sections and the tail sections of the left / right side rods, the stop collar rods are arranged on the split bolts at the tail sections in a sleeving way, the nuts of the split bolts in the middle sections of the left / right side rods are tightened, and the web side formwork of the stiffened concrete beam is tightly clamped by the left / right side rods. The fastening clamp has the advantages that the traditional fastening mode of forming the holes in the web of the steel beam and threading the split bolts is replaced by the product, the problems that the inaccurate alignment of formwork holes on the two sides of the beam causes difficult construction and repeated formwork hole forming are effectively solved, and the concrete molding quality is ensured.

Description

technical field [0001] The invention relates to the construction of a building structure component, in particular to a reinforcement fixture for a formwork on the ventral side of a rigid concrete beam. Background technique [0002] With the development of society, buildings are gradually developing in the direction of super high-rise and large-scale, and the main structure design adopts steel-concrete structural forms more and more. During the construction of steel-concrete structures, steel beams are generally reinforced by means of double-tensioned screws and steel pipe keels. The disadvantage of this reinforcement method is that it is necessary to perforate the web of the shaped steel beam, and the alignment of the holes in the web and the holes in the formwork often occurs. Larger difficulties have affected the progress of the project. Contents of the invention [0003] The purpose of the present invention is to provide a stiffened concrete beam ventral formwork rein...
