Description
Technical field
The utility model relates to bridge pier column constructions, in particular to a kind of to facilitate the steel form for increasing abutment pier pier seam.
Background technique
The structural system of straddle type monorail rail tracks has system of simple supporting, continuous system, continuous rigid frame system.At present in the world
It has runed and in the cross-saddle single-track traffic built, track girder generallys use prestressed concrete Simple Rail Bearer.
The continuous rigid frame PC guideway beam structural system that Wuhu City's rail traffic uses.The system uses simple-supported thencontinuous
Method construction, the form of construction work of simply supported-to-continuous system is by the batch Prefabrication of simply supported beam and the superior function of continuous beam
Combine, its main feature is that first press simply supported beam scale fabrication and erection construction, after by pouring continuous segment, tensioning second phase prestressing force
Muscle and dismounting temporary support, complete the conversion by freely-supported to continuous system, realize the mode of batch Prefabrication to accelerate to connect
The construction speed of continuous beam, has the advantages of saving cumbersome branch die process, having taken into account freely-supported and continuous system.In order to guarantee longitudinal direction
It adjusts, needs that the pier seam of 5cm is arranged in continuous rigid frame abutment pier, but since the pier seam between steel form is smaller, need to stitch in pier
Middle filled and process stitches to increase pier, and this mode for increasing pier seam is relatively complicated and easily impacts to environment.
Utility model content
The purpose of the utility model is to provide a kind of steel forms for facilitating and increasing abutment pier pier and stitching, and have and facilitate increase steel form
Between pier seam the advantages of.
The above-mentioned technical purpose of the utility model has the technical scheme that
It is a kind of to facilitate the steel form for increasing abutment pier pier seam, including two pieces of steel forms for being spliced to form cavity, steel rib and to drawing
Bolt, the steel rib are fixed on the outside of the surrounding of steel form, and split bolt is arranged on adjacent steel rib, two pieces of steel forms
Between be formed with pier seam, rotating bar is equipped in pier seam, the one end of the rotating bar on the outside of steel form is equipped with threaded portion,
Nut is threaded on the threaded portion；
Two pieces of steel forms are outward extended with connecting plate towards the two sides that pier stitches respectively, and connecting plate is located under threaded portion
Side, the connecting plate are equipped with bolt.
By using above-mentioned technical proposal, rotating bar is raised by tool, steel form is placed on to the two sides of swingle,
Two pieces of steel forms are tensed by steel rib and split bolt, rotating bar is clamped between two pieces of steel forms, finally leads to again
Bolt is crossed further to clamp rotating bar, to keep the pier of 5cm to stitch.After use, by tool rotating nut by rotating bar
Back-out.More convenient to increase pier seam operation in this way, operating efficiency is higher.
Further, the nut is fixedly connected with annular slab, the diameter of the annular slab on the side of steel form
Greater than the diameter of nut.
By using above-mentioned technical proposal, the setting of annular slab increases the contact area of tool and nut, so that nut
It is not easy to slip from tool, nut rotation is more steady, accelerates rotating bar taking-up.
Further, two connecting plates are relatively set with fixed block close to the side of rotating bar, on the fixed block
It is equipped with half slot of positioning for annular slab rotation.
By using above-mentioned technical proposal, the setting for positioning half slot not only can play position-limiting action to the rotation of nut,
So that nut is not easily shifted during rotation, it can also play a supporting role to nut, so that nut begins during rotation
Whole and rotating bar coaxial line, so that rotating bar taking-up is more steady.
Further, the nut is equipped with card slot far from the side of annular slab, is arranged with swivel becket in the rotating bar, institute
It states swivel becket and is equipped with the limited post cooperated with card slot close to the side of nut, be fixedly connected with and rotating bar axis on the swivel becket
The vertical driving lever of line；
Half slot of limit is equipped on two fixed blocks, the swivel becket is located in half slot of limit.
Limited post is embedded into card slot when nut needs to rotate by using above-mentioned technical proposal, rotating lever,
Thus to drive nut to rotate.It is more laborsaving when making rotating nut provided with driving lever, it is more convenient.Swivel becket is placed in limit half
In slot, support and position-limiting action can be played to the rotation of fixed block, more convenient swivel becket turns nut.
Further, spring, and spring are equipped between side of the swivel becket far from nut and the side wall of half slot of limit
One end be fixedly connected with the side wall of half slot of limit, the other end and swivel becket contradict.
It is done due to the setting of fixed block so that driving lever exists when rotating nut by using above-mentioned technical proposal
It relates to, needs after swivel becket turns an angle, limited post is detached from from card slot, then adjust the position of driving lever, then will limit
Position column is embedded into card slot, and continues to rotate nut.When the setting of spring is so that limited post is detached from from card slot, swivel becket is risen
It to the effect of buffering, reduces swivel becket and is directly contacted with the side wall for limiting half slot, and swivel becket is caused to damage.
Further, the limited post is equipped with guide surface towards the side of card slot side wall.
By using above-mentioned technical proposal, be equipped in the more convenient limited post insertion card slot of guide surface, reduce limited post with
Swivel becket collides and damages limited post.
Further, the slot bottom of half slot of half slot of the positioning and limit is equipped with ball.
By using above-mentioned technical proposal, annular slab contacts with the slot bottom of half slot of limit in the course of rotation and generates cunning
Dynamic friction accelerates the abrasion of annular slab, and the abrasion of annular slab can be reduced equipped with ball, extends the service life of annular slab.
The abrasion of swivel becket can be reduced by limiting the ball in half slot equally, extend the service life of swivel becket.
Further, the driving lever is equipped with anti-skid chequer far from one end of swivel becket.
By using above-mentioned technical proposal, anti-skid chequer increases the friction between driving lever and the tool of rotating lever, so that
Tool is not easy to slip from driving lever during the work time, improves work efficiency.
In conclusion the utility model has the following beneficial effects:
1. using rotating bar, threaded portion and nut, the pier between steel form is enabled to stitch the effect that distance is maintained at 5cm
Fruit；
2. using half slot of annular slab and positioning, the effect of support and limit can be played to the rotation of nut；
3. using swivel becket, card slot, limited post and driving lever, it can play and facilitate rotating nut, so that taking-up be facilitated to turn
The effect of lever.
