Description

M315269 VIII. New description·· 【New technical field of the invention】 This creation is about a screw structure. After the drill body of the front of the Japanese priest is used in the through-building formwork, the screw can be broken and the nut can be used. Through the break and the snail: the user uses the screw-tail structure for the building formwork. [Prior Art] Please refer to Figure 1A, Figure 1B and Figure 1C. JL is a schematic diagram of the fixing method of the feather left. The general construction personnel will properly fix all the building templates in the county, and then the cement will be pre-set = = = = A, the common construction method is mainly to drill the first drill on the pine board 1 - 12, so that Template u, two = wide 12,. As shown in Fig. 1B, after the screw 13 of the pure plate is built, the two openings 112 are opposite to each other. As shown in Fig. C, after the screw 13 is inserted into the opening 112, (2), the two ends of the screw 13 are respectively locked with the pressing pieces 14, 15 and the nuts 16, 17 and the templates u, 12. Since the fixing method must first be on the template =' and then the screw is used to open the hole, it is more inconvenient to spend more B-inch in the construction day. Li Ming's examination of Figure 2 is a diagram of another known method of fixing a building template. ^ The constructor uses an electric drill 22 provided with a sleeve 21, and sleeves a screw 24 having a drill bit 23 on the sleeve, and the combination of the screw 24 and the sleeve 21 is directly screwed in, and then utilizes this. The screw 24 having the drill bit 23 5 M315269 is drilled directly on the stencils 25, 26, and after the screw 24 passes through the stencils 25, 26, the sleeve 21 and the screw 24 are separated by screwing. The combination with the sleeve 21 and the disassembly method must take a long time, which is extremely inconsistent with the inertia of the construction and less convenient. [New content] In view of this, in order to avoid the lack of the above-mentioned prior art, the present invention proposes a fixed screw tail structure for a building formwork, the main purpose of which is to provide a construction worker with a reduced construction time and a reduced construction complexity. The fixed screw tail structure is fixed to facilitate quick integration and disassembly with an electric drill sleeve. In order to achieve the above object, the present invention proposes a fixed screw tail structure for a building formwork, which comprises: a rod body having a tip end portion with a front end portion and a thread formed on the outer edge thereof; The rear end portion is formed with one-way tapered shape, two-way oblique shape, straight-line groove and straight-line convex block, and is matched with an electric drill sleeve to set a reverse chamfering shape and a reverse V-shaped beveling The space of the straight, straight and straight grooves is combined. In summary, the fixed screw structure of the fixed screw structure proposed by the present invention can not only reduce the construction complexity and save the construction time, but also the fixed screw structure proposed by the present invention can be compared with the conventional nuts and the forced nuts. The tight film sharing is not only convenient for materials, but also has no cost increase. M315269 [Embodiment] _: can? =, the levy, purpose and function have a more advanced cognition ', cautious % affiliation & the detailed description of the following: 〆 > : Figure: A 'the system is A preferred embodiment of the creation is for a building 4: a snail-spindle body. A schematic view of a first embodiment. The fixed screw structure has a threaded ί body and a first body 仏 'the outer edge of the rod body 41 is formed: the eve, the text of the body of the drill body 42a is formed with a tip end portion, and the tip end of the 'M22 tip The distance d4 is larger than the outer diameter of the rod 41, and the first body 42a is formed with a neck which is connected to the rod 41, and the outer diameter d6 of the neck 424 is smaller than the outer diameter of the rod 41. Since the neck is similar (the diameter d6 is small), a user can be broken from the position of the neck 424 to separate the body-drill 42a from the shaft 41. The rod body 41 ^ is integrally formed, and the tip end portion 422 can be formed into a flat cone shape. Except as disclosed in FIG. 2, the first drill body has a triangular pyramid structure, and FIG. 3b discloses a separate structure. The second drill body 42b has a peach-shaped structure, and is still provided with the neck portion 426. In addition to the function of providing the drilled-in construction of the anti-A end of FIG. 3A, the rear end of the second drill body 42b is curved at 427. It can be used to scrape the burrs generated by other fixed screws that are drilled into the building formwork, and has better practicability. ~ Please also refer to Figure 4A to Figure 4D, which is the preferred embodiment of the creation = the first, second, third and fourth structures of the mosquito screw tail of the building template, Figure 4 A discloses that the front end of the rod body 41 has a drill body 42 (shown in FIG. 3), and the rear end of the first tail 43 is formed with an early oblique shape to fit an electric drill sleeve ( The figure is not shown) is combined with the corresponding reverse chamfered space; the fourth tail 44 M315269 disclosed in Fig. 4 is a bidirectional beveled shape, which is matched with an electric drill sleeve to set a corresponding reverse V-shaped oblique The chamfered space is combined; FIG. 4C discloses that the third rod tail 45 is a linear trough 451, which is combined with an electric drill sleeve to set a corresponding linear lug space (not shown); FIG. 4D discloses the fourth The tail 46 is a linear projection 461 which is combined with an electric drill sleeve to provide a corresponding straight groove space (not shown). Please refer to FIG. 5A, FIG. 5B and FIG. 5C at the same time, which is a schematic diagram of the fixing manner of the fixed screw tail structure of the building template for the preferred embodiment. As shown in FIG. 5A, the tail end of the fixed screw structure 40 can be screwed with a sleeve 51 having an internal thread, and the sleeve 51 can be combined with a driving device 52 (such as an electric drill), and the constructor starts the driving device. After 52, the sleeve 51 will rotate and drive the rod 41 to rotate. Due to the special design of the tip end portion 422 and the neck portion 424 of the front end of the drill body 42, when the constructor drills the chips on the templates 53, 54, the chips can be discharged, so that the rod body 41 and the drill body 42 can be easily Pass through the templates 53, 54. As shown in Fig. 5B, the rod body 41 is separated from the sleeve 51 at this time, and the drill body 42 is broken from the position of the neck portion 424 to separate the drill body 42 from the rod body 41. As shown in FIG. 5C, finally, the pressing pieces 55, 56 and the nuts 57, 58 are nested and screwed from both ends of the rod 41, thereby fixing the templates 53, 54 to complete the drilling and fixing. jobs. In the embodiment disclosed in the above FIG. 3, the fixing manners shown in FIG. 4A to FIG. 4C can be applied. The tip end is not limited to a flat cone shape. Anyone who has a pointed tip and can be drilled is an equal embodiment of the creation. The emphasis is on the design of the arc portion for easy chip evacuation and the width of the arc portion. It is larger than the outer diameter of the rod, and the outer diameter of the neck must be smaller than the outer diameter of the rod. M315269 In combination with the above, the <tail" tail structure, the right to propose the fixed screw degree for the building formwork, convenient to apply; reduce the time required for construction and reduce the complicated construction of the construction, and can work without causing the drill body The card worker was injured. (4) Avoiding the exposure of the drill bit and causing the limitations of the above-mentioned ones. The scope of this creation is equally changed and modified to the spirit and condition of the creation. It is only a preferred embodiment of the present invention, and cannot be surrounded. That is to say, according to the scope of patent application for the creation of this article, it will not lose the essence of the creation, and it will not be considered as the scope of the creation. Therefore, it should be regarded as further implementation of this creation.
