Abstract
The invention discloses a threadless self-locking wall penetrating pulling rod. The pulling rod is composed of an opposite-pulling rod, an L-shaped fixed part, a fixed column, a fixed nut, a hollow screw rod and an opposite-pulling nut. The opposite-pulling nut is screwed on the hollow screw rod, and one end of the opposite-pulling rod is sleeved with the hollow screw rod; the fixed nut is screwed at the lower end of the fixed column, and the fixed column penetrates a fixed column penetrating hole of the L-shaped fixed part, and the L-shaped fixed part leans against the wall; the opposite-pulling rod penetrates through a wall, and then is sequentially inserted into a first penetrating hole of the L-shaped fixed part and a second penetrating hole of the fixed column; the hollow screw rod slides to be blocked by a limiting block of the opposite-pulling rod, and then the fixed nut is screwed to enable the other end of the opposite-pulling rod to be fixed; and finally, the opposite-pulling nut is rotated towards the other end of the opposite-pulling rod to achieve the aim of tightening the opposite-pulling rod. The threadless self-locking wall penetrating pulling rod can achieve the aim that a common reinforcing steel bar is used for replacing the screw rod, and therefore the aims that materials are conveniently taken, and in the wall penetrating process, a PVC casing pipe is not needed are achieved; and the threadless self-locking wall penetrating pulling rod is simple in structure, convenient to dismount and large in turnover frequency.
Description
Technical field
The present invention relates to a kind of building engineering construction with to pull bar, particularly a kind of wall-through pull rod.
Background technology
The cast-in-place concrete structures such as the concrete wall of concrete structure, heavy in section beam generally adopt the drawknot of form as inner and outer template of Screw arbor with nut at both-ends in the process of inside and outside side template strengthening.Traditional Screw arbor with nut at both-ends as shown in Figure 1, is made up of a screw rod A and two mountain type card B and two nut C being positioned at screw rod two ends.The screw rod crossing wall, for ease of reusing, also needs outward to overlap pvc pipe at screw rod.
In prior art, also has the Screw arbor with nut at both-ends structure of other structures multiple, pretensioner for form cable such as disclosed in Chinese patent application 201210035472.1, comprise outer sleeve, inner sleeve, crescent moon rule, handle block, inner sleeve and outer sleeve are the cylinder of hollow, the internal diameter of outer sleeve is greater than the external diameter of inner sleeve, bar shape trench hole is provided with in the middle part of outer sleeve, the top of inner sleeve is provided with external screw thread, bar shape trench hole is opened in the bottom of inner sleeve, inner sleeve is enclosed in outer sleeve, and inner sleeve top is stretched out from the upper end of outer sleeve; Handle block is provided with internal thread and is threaded connection with the external part of inner sleeve, and handle block is provided with handle socket; Crescent moon rule are L shape, and the notch place of the corner that crescent moon is advised and inner sleeve bar shape trench hole lower end is hinged, and what crescent moon advised back is semicircle, and semicircular edge is provided with ratchet, and the another side at crescent moon rule back is flattened edge.A kind of reinforcing bar butterfly button again such as disclosed in Chinese patent application 201320240854.8, comprises two reinforcing bar fasteners, and the two ends of reinforcing bar fastener bend respectively clockwise and counterclockwise, are welded together between two reinforcing bar fasteners by rebar connector; Rebar connector is provided with screw hole, and one end of screw rod makes reinforcing bar butterfly button coordinate with steel pipe through screw hole, the other end and nut screw connection.This utility model is drawn materials facility, makes simple, easy to use, can save construction cost, and intensity is higher, can guarantees the firm of construction formwork supporter better.
The Screw arbor with nut at both-ends ubiquity of above-mentioned prior art expends pvc pipe, removes inconvenience and remove unsafe shortcoming time through walls, and part also exists baroque shortcoming.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of without the tight wall-through pull rod of screw thread self-locking, of the present inventionly can realize substituting screw rod with plain bars without the tight wall-through pull rod of screw thread self-locking, thus it is convenient and through walls without the need to using the object of PVC sleeve pipe to realize drawing materials, and structure simple, remove convenient, the number of turnover is large.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of without the tight wall-through pull rod of screw thread self-locking, by to pull bar, L shape fixture, fixed leg, hold-down nut, cored screw and to drawing nut to form, described L shape fixture has the horizontal stator and longitudinal stator that intersect vertically, described longitudinal stator offers the first perforation, described horizontal stator offers fixed leg perforation, the upper semisection of described fixed leg offers the second perforation and lower semisection has screw thread, described cored screw has external screw thread, described one end to pull bar is fixed with limited block, described to drawing nut to twist in described cored screw, described cored screw is placed on described one end to pull bar and stops by described limited block, described fixed leg is through in the fixed leg perforation of L shape stator, hold-down nut is twisted in fixed leg lower end, described to first perforation of the pull bar other end through L shape stator and the second perforation of fixed leg, tighten hold-down nut to make to fix the other end of pull bar, rotate drawing nut with tension to pull bar to the other end of pull bar.
The present invention in order to the further technical scheme solving its technical problem and adopt is:
Say further, described to drawing nut to be plateau nut.
It is preferred that described limited block is one section of reinforcing bar of the one end be welded in pull bar, make to form T connector to one end of pull bar.
It is preferred that described to drawing nut to be hex nut.
It is preferred that described hold-down nut is hex nut.
Say further, described is plain bars to pull bar.
The invention has the beneficial effects as follows: of the present invention without the tight wall-through pull rod of screw thread self-locking by pull bar, L shape fixture, fixed leg, hold-down nut, cored screw and to drawing nut to form, during use, first will twist on cored screw to drawing nut, then cored screw is placed on to pull bar one end, hold-down nut is twisted in fixed leg lower end, fixed leg is through in the fixed leg perforation of L shape fixture, make L shape fixture by wall, insert in the first perforation of L shape fixture and the second perforation of fixed leg successively after through walls to pull bar again, and cored screw is slid into be subject to the stop of the limited block to tie rod end, then hold-down nut is tightened to make to fix the other end of pull bar, finally by drawing nut to reach the object of tension to pull bar towards rotating the other end of pull bar.Of the present inventionly can realize substituting screw rod with plain bars without the tight wall-through pull rod of screw thread self-locking, thus it is convenient and through walls without the need to using the object of PVC sleeve pipe to realize drawing materials, and structure simple, remove convenient, the number of turnover is large.
