Abstract
The utility model provides a circular arc building templates fastener, includes steel band, bolt, connecting block and nut, all be provided with coaxial through -hole on first connecting block, second connecting block and steel band, the bolt passes coaxially with the nut cooperation, connect the both ends of steel band behind the through -hole. The outer terminal surface of the through -hole on first connecting block and second connecting block is provided with circular chamfer. The outer terminal surface of the through -hole on the steel band is provided with circular chamfer. The utility model discloses simple structure, the steel band can use for ever, owing to do not have the screw thread in the connecting block, the phenomenon damaged can not appear, consequently can repeat repetitious usage, the bolt damage the back directly change the bolt can, need not change the steel band, and, can not make the bolt scrape at the perforation in -process and the terminal surface edge of through -hole in the circular chamfer of the terminal surface setting of through -hole and bump the problem that causes the difficulty of perforating, improved the efficiency of connecting the fastening.
Description
Technical field
The utility model relates to circular arc construction formwork securing member.
Background technology
Circular arc construction formwork needs to carry out connecting with securing member fastening in work progress, Authorization Notice No. is that the Chinese utility model patent of CN202544402U discloses a kind of Novel arc construction formwork securing member, it comprises steel band, the first hold-down nut, the second hold-down nut, screw bolt and nut (actual is bolt head), there is problem in this product: 1, the first hold-down nut is connected by threaded engagement with bolt with the second hold-down nut in use, when connecting, operation is very inconvenient, needs to screw bolt for a long time; 2 once the first hold-down nut and the second hold-down nut internal thread damage after, whole steel band just can not employ, and causes great waste.
Utility model content
For the problems referred to above of existing product, it is rapidly convenient that the purpose of this utility model is to provide one to be fixedly connected with, and only need change bolt, the circular arc construction formwork securing member that steel band can forever use after bolt failure.
The technical scheme in the invention for solving the technical problem is: a kind of circular arc construction formwork securing member, comprise steel band, bolt and contiguous block, the two ends of described steel band are bent into the groove adapted with the first contiguous block and the second contiguous block respectively, described first contiguous block and the second contiguous block are fixed in described groove, it is characterized in that, this securing member also comprises the nut coordinated with described bolt; Described steel band on described first contiguous block, the second contiguous block and the side relative with the second contiguous block with described first contiguous block is provided with coaxial through hole; Described bolt through after coaxial described through hole with described nut screw connection, the two ends of described steel band are connected.
Further, the outer face of the through hole on described first contiguous block and the second contiguous block is provided with rounded corners.
Further, the outer face of the through hole on described steel band is provided with rounded corners.
The beneficial effects of the utility model are: its structure is simple, and steel band can permanently use, and owing to not having screw thread in contiguous block, there will not be the phenomenon of damage, therefore can repeatedly use, after bolt failure, directly change bolt, do not need to change steel band; And the rounded corners arranged at the end face of through hole can not make bolt cause with the end face edge scratching of through hole in perforation procedure to bore a hole the problem of difficulty, improves and connects fastening efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is part preferred embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the utility model contiguous block and part steel band structural representation;
Fig. 3 is the sectional view of Fig. 2 structure.
In figure, 1 steel band, 11 through holes, 111 rounded corners, 2 bolts, 31 first contiguous blocks, 311 through holes, 3111 rounded corners, 32 second contiguous blocks, 4 nuts.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail:
As shown in Figure 1 to Figure 3, the nut 4 that the utility model comprises steel band 1, bolt 2, contiguous block and coordinates with described bolt, the two ends of described steel band 2 are bent into the groove adapted with the first contiguous block 31 and the second contiguous block 32 respectively, and described first contiguous block 31 and the second contiguous block 32 are fixed in described groove; Described steel band 1 on described first contiguous block 31, second contiguous block 32 and the side relative with the second contiguous block 32 with described first contiguous block 31 is provided with coaxial through hole, described bolt 2 coordinates with described nut 4 through after coaxial described through hole, is connected at the two ends of described steel band 1.First contiguous block 31 and the second contiguous block 32 directly adopt through hole and do not adopt screwed hole, substantially increase installation joint efficiency, and contiguous block can not be damaged, thus steel band can be made forever to use.
As shown in Figures 2 and 3, collide to prevent the screw thread of the outward flange of through hole and bolt 2 cause bolt 2 through or exit through hole time inconvenient, the outer face of the through hole 311 of described first contiguous block 31 is provided with rounded corners 3111.And the outer face of through hole 11 on described steel band 1 is provided with rounded corners 111.In like manner, be also provided with rounded corners in the outer face of the through hole on the second contiguous block 32, the outer face of the through hole on the described steel band welded with the second contiguous block is also provided with rounded corners.
The above has made detailed description to preferred embodiment of the present utility model and embodiment by reference to the accompanying drawings; but the utility model is not limited to the above-described embodiment and examples; for those skilled in the art; without departing from the concept of the premise utility; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
