Problems solved by technology

Compared with bare tapered nuts without nut sleeves, the success rate of removing tapered nuts with plastic nut sleeves is much higher, but about 10% of the tapered nuts cannot be removed
In addition, due to the strong adhesion between the conical nut and the concrete, when the conical nut is taken out, it is easy to damage the nut disassembly wrench, which virtually increases the project cost
The cost of the plastic nut sleeve is high, and the plastic nut sleeve and the tapered nut are easy to loosen, and the wet concrete material is easy to enter, making it difficult to take out the tapered nut; in addition, due to the high strength of the plastic material, the bite with the tapered nut is serious. It is also one of the reasons why the tapered nut is difficult to remove

Embodiment Construction

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] Such as figure 1 Shown, the tapered nut combination of the present invention comprises tapered nut 1, the fixed bolt 2 that is fixedly connected with tapered nut 1 large end, the tail muscle 3 that one end is fixedly connected with tapered nut small end, wrapping tapered nut 1 Nut rubber cover 4, the taper nut 1 two ends of the present embodiment have different threaded holes, and the taper nut 1 two ends are respectively fixedly connected with different diameters, different pitches of fixing bolts 2, tail ribs 3 threaded ends 31. Screw the tail tendon 3 into the tapered nut 1 from the small end plane 12 of the tapered nut, and screw the fixing bolt 2 into the tapered nut 1 from the big end plane 11 of the tapered nut, so that the tail tendon 3, the tapered nut 1 and the fixing bolt 2 are connected into a combination of embedded nuts that can jointly bear the lo...

Abstract

The invention discloses a conical embedded nut assembly for creeping formwork construction. The conical embedded nut assembly comprises a conical nut, a fixed bolt fixedly connected with the big end of a conical pre-nut, a tail rib fixedly connected with the small end of the conical nut, and a nut rubber sleeve, wherein the shape of the nut rubber sleeve is engaged with the shape of the conical nut, binding port annular reinforcing ribs are arranged at the binding ports of two ends of the nut rubber sleeve, and the nut rubber sleeve wraps the big end plane and the small end plane of the conical nut. An installation method for the conical nut assembly comprises the following steps of: 1) coating butter on the peripheral surface of the conical nut; 2) sheathing the conical nut rubber sleeveon the conical nut; and 3) fixing the embedded nut assembly on one side of a formwork through fixing bolts. The conical nut assembly tightly wraps the conical nut in a 'covering sleeve' shape so as to ensure that a wet concrete material cannot intrude into the nut rubber sleeve and bring convenience to take-out of the conical nut.

Description

technical field [0001] The invention relates to a climbing formwork construction tool for cast-in-situ vertical reinforced concrete structures in construction engineering, in particular to a tapered nut combination bearing formwork loads, and also to a method for installing the tapered nut combination, which belongs to the technical field of building construction . Background technique [0002] Hydraulic self-climbing formwork is a relatively advanced construction method for cast-in-place vertical reinforced concrete structures. On the basis of buildings or structures, a section of formwork is installed along the periphery of the structure at one time. , continuously lift the formwork to complete the pouring and molding of the entire building. During the construction of hydraulic self-climbing formwork, only one assembled hydraulic sliding formwork is used for the entire structure, and the concrete is kept pouring continuously. The construction speed is fast, and constructi...
