Abstract
The invention discloses an integral nut gasket fastener which comprises a butterfly nut, a square gasket, a steel washer and a steel gasket. The square gasket, the steel washer and the steel gasket are arranged on the butterfly nut in a sleeving manner, and the square gasket and the steel gasket are fixed to the lower end of the butterfly nut through the steel washer. According to the integral nut gasket fastener, the construction processes of a formwork strengthening system are reduced, the work efficiency of constructors of a construction engineering formwork is improved, the construction progress of the formwork engineering is accelerated, the construction quality of formwork strengthening is ensured, and economic benefits are obvious.
Description
Technical field
The present invention relates to a kind of fastening piece, particularly a kind of integrated type nut shim fastening piece.
Background technique
Template subdivisional work is the important component part of the sub-partitioned project of concrete structure, and the reinforcement system of template is the important construction system of template subdivisional work.Adopt advanced formwork reinforcement system technology, for raising construction quality, accelerating construction progress and reduction construction cost, all tool is of great significance.
The formwork reinforcement systems such as basis, wall, post are mainly divided into support system and to drawing system, template to drawing system by haling bar to drawing high, cone, nut, pad combine.To the whole process of drawing the construction of system through formwork reinforcement, its construction quality determines the firm of template and safety.In current nuclear power projects, template has drawing Problems existing in system: 1) to drawing nut and pad in system to be separate to use, need single-piece to purchase, and construction usage process needs classified storage, receives, installs, and adds user cost; 2) nut and these two kinds of objects of pad all belong to drawing the middle-size and small-size component and fitting of reinforcement system, and when separately using, job site is easily lost, and is unfavorable for the storage management of circulation material; 3), in formwork erection and demolishing process, must singlely carry out installing and remove, thus adding a working procedure, the efficiency that impact is constructed.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of integrated type nut shim fastening piece easy for installation.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of integrated type nut shim fastening piece, it is characterized in that: comprise wing nut, square washer, Steel Washer and steel plate washer, described square washer, Steel Washer and steel plate washer are all set on wing nut and square washer and steel plate washer are fixed on wing nut lower end by Steel Washer.
Further, described wing nut is made up of nut, support arm and both sides butterfly handle, and support arm is sheathed to be fixed on outside nut, and both sides butterfly handle is perpendicular to support arm upper surface and be fixed on support arm both sides.
Further, being provided with hollow hemisphere in the middle of described square washer and arching upward portion, in the middle of upper end, portion of arching upward, having the through hole for passing through pull bar.
Further, described in arch upward between portion's surrounding and square washer bottom surface and be provided with some stiffening ribs, some stiffening ribs are evenly distributed on the portion's surrounding that arches upward.
Further, described Steel Washer adopts jump ring.
Further, described wing nut, square washer, Steel Washer and steel plate washer all adopt QT500-7 nodular cast iron material.
Further, described wing nut, square washer, Steel Washer and steel plate washer appearance are zinc-plated.
The present invention compared with prior art, has the following advantages and effect:
1, processing and fabricating is simple, practicality is comparatively strong, be applicable in template construction to tension solid system;
2, all component combinations of fastening piece become an entirety, and parts are not easily lost, and to be disposablely in place when installing, and step is few, install simple and fast;
3, wing nut reduces the load of Screw arbor with nut at both-ends screw thread, extends the working life of fastening piece.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of integrated type nut shim fastening piece of the present invention.
Fig. 2 is the schematic diagram of wing nut of the present invention.
Fig. 3 is the schematic diagram of square washer of the present invention.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
As shown in the figure, a kind of integrated type nut shim fastening piece of the present invention, comprise wing nut 1, square washer 2, Steel Washer 3 and steel plate washer 4, square washer 2, Steel Washer 3 and steel plate washer 4 are all set on wing nut 1 and square washer 2 and steel plate washer 4 are fixed on wing nut 1 lower end by Steel Washer 3.By such structure, integrated type nut shim fastening piece processing and fabricating of the present invention is simple, practicality is comparatively strong, be applicable in template construction to tension solid system.Wing nut 1, square washer 2, Steel Washer 3 and steel plate washer 4 overall package link into an integrated entity, thus avoid the problem that drops of part, only need when installing directly to carry out integrated type installation simultaneously, save operating procedure, improve the efficiency of installation, thus effectively reduce construction cost, solve store keeping, decrease working procedure, thus improve the work efficiency of template construction, accelerate the progress of form work engineering.
Wing nut 1 is made up of nut 5, support arm 6 and both sides butterfly handle 7, support arm 6 is sheathed to be fixed on outside nut 5, both sides butterfly handle 7 is perpendicular to support arm 6 upper surface and be fixed on support arm 6 both sides, by the wing nut of this structure, decrease the load of Screw arbor with nut at both-ends screw thread, extend the working life of fastening piece.Being provided with hollow hemisphere in the middle of square washer 2 to arch upward portion 8, in the middle of upper end, portion 8 of arching upward, having the through hole 9 for passing through pull bar.Some stiffening ribs 10 are provided with between portion 8 surrounding that arches upward and square washer 2 bottom surface; some stiffening ribs 10 are evenly distributed on the portion of arching upward 8 surrounding; Steel Washer 3 and steel plate washer 4 can be protected interior by such square washer 2, and structure is more compact attractive in appearance and outside concrete disintegrating slag can be avoided to cause damage to Steel Washer 3 and steel plate washer 4.
Steel Washer 3 adopts jump ring, conveniently mounts and dismounts.Wing nut 1, square washer 2, Steel Washer 3 and steel plate washer 4 all adopt QT500-7 nodular cast iron material.Wing nut 1, square washer 2, Steel Washer 3 and steel plate washer 4 appearance are zinc-plated.
Feedback effects is put into practice good through onsite application, more practical compared with separating use with general nut, pad.Fastening piece of the present invention is that the one of formwork reinforcement system method is improved, and adopts die casting to form, makes processing simple, can produce in batches, can be applied to industry with civil building formwork reinforcement system.
Above content described in this specification is only made for the present invention illustrating.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of specification of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
