4. Description of creation (l) [Technical field to which the new type belongs] This creation is applied to the technical field of engineering, especially an engineering board mold fixing device that can be repeatedly used to reduce costs and has environmental protection effects. . [Previous technology] According to the general project, during the grouting, in order to increase the strength and positioning effect of the plate mold, a fixing device is usually provided between the plate molds, and the conventional engineering plate ^ fixing device, as shown in the third figure It is provided with a screw 60 with an external thread on the outer periphery, and the screw 60 can pass through a die (not shown in the figure), and the screw 60 is sleeved at two ends of the die through the die. A positioning nut 7 0 ′ and a screw cap 80 are locked at both ends of the screw 60, and the two screw caps 80 are respectively pressed on the outer peripheral surface of the two positioning members 70, so as to handle the two sides of the mold. strength. 9 w However, 'the conventional engineering mold fixing device is still missing, so after the completion of grouting in the mold, the screw cannot be pulled out because of the external thread section formed on the periphery', and the mold can only be two The end of the nut and the positioning member are loosened] and then cut off the part of the screw protruding from both sides of the die, so that there is still a part of the screw in the die, so that the screw cannot be used repeatedly The cut-off of the screw segment also results in waste, which greatly increases the cost of the project and the problem of environmental protection. [New content] In view of the fact that the conventional mold fixing device for conventional engineering is actually used, the creator still has the disadvantages of high cost and environmental protection.

Page 5 M252766, Creative Instructions (2) Design. The creation of this > + system is to provide a kind of engineering plate mold fixedly installed to greatly reduce the ejection of the work rod, so that the screw can be used repeatedly, "in order to achieve ΐ 本 'and improve Environmental protection. "The paragraph is to mention;" The purpose of the dagger, the technical rod used in this creation, the screw mold fixing device for the outer periphery of the screw, 'the system includes: the second cover-the outer body, and the outer rod-the body shot Since the two holes of the screw are formed with a-mouth and a nut, one end surface M of the two nuts and one surface of the outer casing are locked. The knife doesn't guilty of this position. [Embodiment] As shown in the first figure, Tailu contains: a plate die fixing device for the process, which is a screw (such as (10)), the screw (texture, and the screw (JL 0) outer 0) An outer screw (20) is formed on the outer periphery, and the outer casing (2: Outer-coated (2 0) is set in a cone shape, and is made of rubber material on the outer periphery.) For the two ends of the screw (1 0):-tapered surface (2 1) 'with a small diameter end (23); ^ becomes a large diameter end (22) and two positioning members (3 0), two fixed screws At both ends of (1 0), i-phase objects (3 0) are respectively put on the surface; two nuts (4 0) and two nuts v 4 0) are locked at the two ends of the outer casing (20). To the screw

The two ends of (1 0) 'and the two nuts (the positioning parts (3 0) are different from the structure of the outer casing, in order to complete the project of this creation, when a plate mold (50) is used for the grouting operation of the project, At least the screw ((20) in the die (50), and the positioning member (30 (40) is sleeved on the outer periphery of the screw (10)), so that two nuts (40) (30) ) For the two sides of the two positioning members (50), and fit with the lubricating oil, while the plate mold (50 cap (40)) and the two positioning members (30) are loosened and borrowed From the outer casing (rod (10)) to the outer casing (20), the screw (10) can be repeatedly used from (23) toward the large-diameter end (22) (10). Reduce the effect of improving environmental protection. 4〇) —The end faces abut one side of the (20) respectively; by the above-mentioned fixing device with a plate mold, when the 'as shown in the second figure, by a screw (1 0) And for covering the outer periphery of the outer body with a cover (1) to penetrate one of the plate molds (50)) ', and the lock nut is tightly fitted to the two positioning members (3 0) to be clamped in the Plate mold shell (2 0) surface coating equipment) When the inner grouting is completed, the two snails can be set into a cone shape from the plate mold (50) to 20), and the small diameter end (2 3) of the snail) is directed to the outer casing (2 0). The small-diameter end exits to reach the cost of the fixing device at the bottom of the screw, and
