Description
Technical Field
The utility model relates to a concrete placement screw rod belongs to stagnant water screw rod technical field.
Background
The stagnant water screw rod that uses at present simple structure when carrying out the opposite draw to the template, need place the filler in the chevron piece inboard to guarantee the fastness of template clamping, preparation, the very big extravagant engineering time of placing of filler. In order to solve the problems, a new technical scheme is provided.
Disclosure of Invention
An object of the utility model is to provide a concrete placement screw rod to solve the problem that proposes in the above-mentioned background art.
In order to realize the purpose, the utility model adopts the following technical scheme: the utility model provides a concrete placement screw rod, includes waterproof screw rod and pull rod, be provided with waterproof board and sleeve pipe on the waterproof screw rod, the waterproof board welds in the middle of the waterproof screw rod, the sleeve pipe symmetry suit is at waterproof screw rod both ends, the pull rod passes through screw thread symmetric connection in waterproof screw rod both ends, is provided with external screw thread and stripper plate on the pull rod, the external screw thread is seted up in the pull rod outer end, and threaded connection has holding nut on the external screw thread, the stripper plate suit is on the pull rod.
Preferably, the sleeve pipe is of a conical structure, the inner end of the sleeve pipe is integrally connected with the elastic rubber sleeve, and the inner end of the elastic rubber sleeve is integrally connected with the inner conical sleeve pipe.
Preferably, the two sides of the extrusion plate are symmetrically connected with fastening screws through threads, the inner ends of the fastening screws are integrally connected with a ball head, and a base is sleeved on the ball head.
Compared with the prior art, the beneficial effects of the utility model are that: the inner end of the elastic rubber sleeve of the utility model is integrally connected with the inner conical sleeve, and the elastic rubber sleeve can be driven to shrink by the inner conical sleeve to wrap and seal the waterproof screw rod when concrete is poured; the base is sleeved on the ball head, so that the pressure application of the tightening screw to the template at different angles and positions can be conveniently carried out, and the firmness of template clamping is effectively improved; synthesize the above the utility model discloses but convenient and fast ground fixes pouring the template, has effectively improved and has pour efficiency.

Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention.
As shown in fig. 1-4, a concrete pouring screw comprises a waterproof screw 1 and a pull rod 2, wherein a waterproof plate 3 and a sleeve 4 are arranged on the waterproof screw 1, the waterproof plate 3 is welded in the middle of the waterproof screw 1, the sleeve 4 is symmetrically sleeved at two ends of the waterproof screw 1, the pull rod 2 is symmetrically connected at two ends of the waterproof screw 1 through threads, an external thread 5 and an extrusion plate 6 are arranged on the pull rod 2, the external thread 5 is arranged at the outer end of the pull rod 2, and the external thread 5 is connected with a fastening nut 7 by screw thread, the extrusion plate 6 is sleeved on the pull rod 2, the sleeve 4 is in a conical structure, and the inner end of the sleeve 4 is integrally connected with an elastic rubber sleeve 8, the inner end of the elastic rubber sleeve 8 is integrally connected with an inner conical sleeve 9, two sides of the extrusion plate 6 are symmetrically connected with tightening screws 10 through threads, the inner end of the tightening screws 10 is integrally connected with a ball head 11, and the ball head 11 is sleeved with a base 12.
The specific use mode is as follows: placing the waterproof screw rod 1 on the inner side of the pouring template, and then enabling the pull rod 2 to penetrate through the pouring template to be in threaded connection with the waterproof screw rod 1; when the template is fixed, the extruding plate 6 is fixed by screwing the fastening nut 7, and then the base 12 is driven by screwing the fastening screw 10 to be tightly attached to the template according to the angle position of the extruding plate 6 and the template; when the template finishes the concrete pouring, the sleeve 4 is tightly attached to the inner wall of the template under the thrust of the concrete, and the inner conical sleeve 9 is driven by the thrust of the concrete to contract the elastic rubber sleeve 8 to seal the two ends of the waterproof screw rod 1, so that the concrete is effectively prevented from leaking along the waterproof screw rod 1 and the pull rod.
The foregoing is a preferred embodiment of the present invention, and for those skilled in the art to understand the teaching of the present invention, the changes, modifications, replacements and variations to the embodiments will still fall within the protection scope of the present invention without departing from the principle and spirit of the present invention.
