Description
Technical field
The invention belongs to technical field of building construction, in particular to a kind of rotation controls whole branch release method and its machinery
System.
Background technique
The form work engineering of skyscraper is developed so far, and the degree of automation of construction operation has had fairly horizontal, such as platform
It is means that modular system, fast mounting-dismounting system etc., which are all by integral disassembly, assembly, to reach the target that saving of work and time improves efficiency.But
As core wall structure part that must be cast-in-place, wherein the template of elevator borehole wall, the shadow at interior right angle is especially by inner space
It rings, template is on the corner mutually twisted, and can not integrally assemble whole promotion, can only dissipate consolidation service, work consuming is time-consuming and affects
The construction speed of flood template.There is the method using aluminium alloy angle mould in the prior art, but after three~tetra- layers of construction, aluminium alloy
Angle mould is deformed by the impact of concreting, and angle mould is stuck after initial set, is caused inner template not promoted integrally, is still forced
It returns in the method in bulk for dissipating and tearing open, could not finally break through old mode.Therefore, for the template of this kind of core wall structure, such as
It is a particularly significant technical problem that, which conveniently and efficiently carries out whole branch demoulding,.
Summary of the invention
The object of the present invention is to provide a kind of rotations to control whole branch release method and its mechanical system to solve above-mentioned ask
Topic.
The present invention is implemented as follows:
A kind of whole branch release method of rotation control, this method control whole branch demoulding mechanical system using a kind of rotation,
The mechanical system includes main rotating shaft and the barrel internal mold plate for being erected at main rotating shaft surrounding, therebetween by stretching transmission dress
It sets and is attached, the stitching portion of barrel internal mold plate is equipped with inflated rubber contracture inflated rubber contracture angle mould；This method includes as follows
Step: main rotating shaft rotation is driven by the rocking handle rotated forward on main rotating shaft, stretching actuator is made to drive pass connected to it
The barrel internal mold plate that connection drive rod pushes out four sides, which moves it to be combined with each other with cylinder external mold, reaches construction requirement wall thickness ruler
It is very little.
Wherein, stretching actuator has lock performance, so that not made by other External force interferences after barrel internal mold plate is in place
It moves dislocation.
Further, after pushing barrel internal mold plate accurate in place by stretching actuator, then to be equipped with barrel internal mold plate pre-
Split bolt is stayed to be connected with cylinder exterior sheathing；Barrel internal mold plate is spliced by being realized after inflated rubber contracture angle mould inflation
The erection of inner and outer template is completed in the closure at place, after the completion can casting concrete；After concrete initial set, unclamps inflated rubber and receive
The exhaust valve of subangle mould, allows the interface of template and concrete in inflated rubber contracture angle mould deflation impact cylinder body, realizes preliminary de-
Mould inverts rocking handle, returns to initial reset condition after making association drive rod drive barrel internal mold plate inside to reach demoulding
Effect.
A kind of rotation for realizing the above method controls whole branch and demoulds mechanical system, including main rotating shaft, in cylinder
Template sets up the template system for constituting square column type along the main rotating shaft surrounding；Several stretchings are equipped at intervals on the main rotating shaft
Transmission device draws high transmission device by being arranged on its four direction in the association drive rod of right-angled intersection and barrel internal mold plate
Connection；Rocking handle is additionally provided on the main rotating shaft, rocking handle is realized by manually or mechanically power by the rotation of main rotating shaft；Cylinder
Four angles stitching portion of internal template is equipped with inflated rubber contracture angle mould.
Further, each stretching actuator includes about two pieces overlappings but discontiguous oval plate, oval plate set
On the main rotating shaft and fixed, upper and lower two blocks of oval plates are arranged in right-angled intersection；Twice arc is equipped on every block of oval plate
Shape slot, this twice arc groove are centrosymmetric arrangement referring to the center of oval plate；One end of the association drive rod is fixedly connected
One sphere, the sphere are embedded in the arc groove and being capable of arcuately slot movements.
Further, the main rotating shaft top is connected with Core Walls Structure cap, and lower part is connected with operating platform, forms the axis of rolling
Holding, which rotates it in main rotating shaft, drives stretching actuator；It is equipped with below the operating platform and to be used to support and be finely adjusted
It is whole to promote platform.
Further, the association drive rod is cased with casing at the position connecting with stretching actuator.
Further, the oval plate is made of a rectangle with two semicircles for being connected to two short side of rectangle.
Further, semicircle internal recessing of the arc groove along oval plate both ends extends to the clockwise length of rectangle
Side midline position, the profile of arc groove and the outer profile of oval plate are consistent.
Compared with prior art, the invention has the following beneficial effects:
The present invention makes to close using the design feature of the arc groove of the oval plate of stretching actuator when rotating main rotating shaft
The steel ball for joining drive rod end arcuately slides in slot, due to the design feature of oval plate, steel ball position different in arc groove
It is different from the spacing between barrel internal mold plate that drive rod is associated with when setting, so as to push out barrel internal mold plate or inwardly receive
Shrinkage porosite opens barrel internal mold plate.Meanwhile inflated rubber contracture angle mould can free contracture characteristic, improve the internal model that mutually restricts of four sides
Plate is allowed to form retractable entirety, by rotating the target for controlling whole branch and demoulding mechanical system completion internal model while contracture
Process, the final whole promotion for realizing barrel internal mold plate and branch are torn open, that is, realize mechanization, the automation of barrel internal mold plate.
