Abstract

The utility model relates to a construction engineering device, in particular to a combined threaded rod, which aims to solve the problem of hidden trouble of leakage or mold blast of the conventional combined threaded rod due to the facts that manufacture and installation are complicated, leakage is easily caused by collision in mold removal, a wooden wedge embedded into a wall is difficult to take out, the wrapping occlusion of concrete is affected due to high temperature expansion of a reinforcing steel bar when the exposed reinforcing steel bar is cut twice and the like. The utility model has the technical scheme that the combined threaded rod consists of a split threaded rod, connectors and tool threaded rods, wherein the head end and the tail end of the split threaded rod are provided with the connectors, and the connectors are connected with the tool threaded rods.

Description

A kind of combined threaded rod
Technical field:
The utility model relates to a kind of building engineering equipment, especially a kind of combined threaded rod.
Background technology:
At present, the underground parking in the construction work, underground store, underground civil air defense constructions and installations, engineering concrete walls such as the water works in the municipal public use engineering, Wastewater Treatment Plant, mistake tunnel, street, subway platform, tunnel all have very high impervious requirement.The conventional job practices of fixed form relative position has the method for outside Zhi Dingyu Screw arbor with nut at both-ends to fix template, and the most frequently used way is to adopt Screw arbor with nut at both-ends to fix template, and weighing apparatus newly placed concrete body of wall lateral pressure guarantees concrete physical dimension.
The utility model content:
The purpose of the utility model is in order to solve; Fabrication and installation are complicated because the conventional combination screw rod exists, the form removal collision is prone to cause seepage, imbed timber wedge in the wall when picking out trouble, exposed steel bar cutting twice, cutting, and reinforcing bar high temperature expands that concrete is bonded the problems such as influence that interlock produces, all can produce hidden leakage defect person or fried mould.
The utility model solves through following technical proposals: a kind of combined threaded rod is made up of Screw arbor with nut at both-ends, connector, instrument screw rod, it is characterized in that said Screw arbor with nut at both-ends is provided with connector in two ends end to end, said connector fastening means screw rod.
The middle part is provided with seal ring on the said Screw arbor with nut at both-ends, and there is helical at two ends.
Wear on the said instrument screw rod body of rod and be loaded with mountain type card, pad, both sides are provided with helical, a side helical connecting bolt, and a side connects connector.
Establish pipe in the said connector, be provided with helical in the pipe.
As pipe helical in the preferred said connector, half the is along pointer direction helical, and half the is the counter clockwise direction helical.
Effective effect of the utility model is: after waterproof, seepage control operation and body of wall pouring were accomplished, the instrument screw rod of this combined threaded rod can manually be removed, and exempts cutting action in the past; The instrument screw rod of removing is reused once more, and during stripping process, gasket construction can drive module and break away from body of wall; Situation such as fried mould when avoiding manual form removal; Significantly speed up the work, reduce labour intensity, reduce the engineering cost expenditure and have good effect.
Description of drawings:
Fig. 1 is a kind of structural representation of combined threaded rod;
Fig. 2 is a kind of embodiment sketch map of combined threaded rod;
Among the figure: 1-chevron card, 2-bolt, 3-instrument screw rod, 4-connector, 5-Screw arbor with nut at both-ends, 6-seal ring, 7-pad, 8-template, 9-steelframe pipe.
The specific embodiment:
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Referring to Fig. 2, a kind of combined threaded rod of present embodiment: mainly include chevron card 1, bolt 2, instrument screw rod 3, connector 4, Screw arbor with nut at both-ends 5, seal ring 6, pad 7.Said instrument screw rod 3 one end helical erection bolts 2; Install chevron card 1 from the other end again, with 3 every groups 2 of instrument screw rods that assembles in twos symmetrical, parallel penetrate template 8, for guaranteeing the effect of this Screw arbor with nut at both-ends when antiseepage is handled; We can install steelframe pipe 9 additional; And utilize chevron card 1 engaging steelframe pipe 9 to fit and go up on template 8, after said a kind of Screw arbor with nut at both-ends was fit into template 8, the end in instrument screw rod 3 penetrates template 8 was installed pad 7 earlier; Install connector 4 again, use connector 4 that Screw arbor with nut at both-ends 5 and the instrument screw rod 3 about it are coupled together.After building the body of wall completion; We rotate counterclockwise connector 4; Instrument screw rod 3 makes connector 4 separate with Screw arbor with nut at both-ends 5, and the connector 4 push-and-pull pads 7 on the instrument screw rod 3 promote template 8 outer moving, and loosening whole template 8 makes this combined threaded rod have demoulding ability; Avoided the manpower crowbar to prize the template demoulding, had the body of wall that the antiseepage pouring is handled well thereby stay.
Specific embodiment described herein only is that the utility model is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
