Abstract
The invention discloses a mechanical core die structure of a precast concrete box beam. The mechanical core die structure comprises a first framework, a second framework, a third framework, a fourth framework, a fifth framework, a sixth framework, a seventh framework, an eighth framework, pulling rods, guide rods, guide blocks and a pulling head; one of the ends of the second framework and the third framework is respectively connected with the first framework as well as being connected with the pulling head arranged on a base through the pulling rods; the guide blocks are fixedly connected to the fourth framework and the fifth framework; one end of each guide rod is inserted into each guide block and while the other end of each guide rod is fixed on the base; when assembling a core die, a surface plate is adhered on the frameworks, and then the pulling head is pushed to push the pulling rods so as to expand the frameworks to form a core die section; when dismounting the die, the pulling head is reversely pulled to pull the pulling rods to contract the core die so as to separate the core die from concrete, and the core die can be pulled out of the box beam. The whole mechanical core die structure is simple, high in practicality and easy to be popularized and used.
Description
Technical field
The present invention relates to reinforced concrete prefabricated box beam applied technical field, especially a kind of machinery core mode structure of box beam.
Background technology
At present, when prefabricated bridge beam, hollow in order to cause, a core must be laid in beam body, after treating that concreting is shaping, again core is split out, and tear a pattern pretty troublesome job often open, because core can cement by concrete in the process of solidifying, and the process of concrete setting also can expand, extruding core, increases concrete cohesive force.The way of tearing core at present open is, workman is arranged to crawl in core, loosen the screw a little, split core, then with hoist engine, core is pulled out, core inside not only narrow space is not easy to operation, and temperature is often up to 50 degrees Celsius, and working environment is more severe, and workman needs inside at least operation 30 minutes, the work of therefore tearing core open can bring more cost to product.
Summary of the invention
Prior art can not meet the needs of people, and for making up prior art deficiency, the present invention aims to provide a kind of machinery core mode structure of box beam.
For achieving the above object, the present invention is by the following technical solutions: a kind of machinery core mode structure of box beam, comprises the first skeleton, the second skeleton, the 3rd skeleton, the 4th skeleton, the 5th skeleton, the 6th skeleton, the 7th skeleton, the 8th skeleton, pull bar, guide post, guide pad and pull head; Described second skeleton is connected with the first skeleton respectively with the 3rd skeleton one end, and is also connected in the pull head on pedestal respectively by pull bar; Described 4th skeleton and the 5th skeleton are respectively fixedly connected with guide pad; Described guide post one end is inserted in guide pad, and another end is fixed on pedestal; Described 6th skeleton is connected with the 8th skeleton respectively with the 7th skeleton one end, and is connected by pull bar with the pull head be arranged on pedestal.
As further technical scheme of the present invention: described 4th skeleton is all connected with pedestal by pull bar with the 5th skeleton upper and lower side.
As further technical scheme of the present invention: described one end guide post other end be inserted in guide pad is bolted on the pedestal in the middle of whole core mold structure.
As further technical scheme of the present invention: described second skeleton and the 3rd skeleton and the 6th skeleton and the 7th skeleton junction are rotational structure.
As preferred version of the present invention: described pull head is slide construction in pedestal.
Compared with prior art, the invention has the beneficial effects as follows: the machinery core mode structure of this box beam, when needs assembling core time, panel is attached on skeleton, then promote pull head, pull head pushing drawing rod, and then skeleton is opened, form one section of core, then by end to end for core same for the multistage core just constituting concrete prefabricated box beam; When can form removal time, only need oppositely to pull pull head, pull head drives pull bar and then shrinks core, core and concrete just can be made to separate, and then core is pulled out case beam.Therefore can avoid manually piercing core inside to go to dismantle core, reduce task difficulty, improve production efficiency; Overall structure is simple, practical, is easy to promote the use of.

Fig. 2 ~ 5 are for promoting the structural representation that pull head struts core when the present invention uses.
The structural representation of Fig. 6 ~ 10 for pulling pull head to shrink core when the present invention carries out form removal.
Wherein: the first skeleton 1, second skeleton 2, the 3rd skeleton 3, the 4th skeleton 4, the 5th skeleton 5, the 6th skeleton 6, the 7th skeleton 7, the 8th skeleton 8, pull head 9, pull head 91, pull head 92, pull head 12, guide post 10, guide post 101, guide pad 11, guide pad 111, pull bar 13, pedestal 14, pull bar 15, pull bar 16, pull bar 17, pull bar 19, pull bar 20, pull bar 21 and pull bar 22.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 ~ 10, in the embodiment of the present invention: a kind of machinery core mode structure of box beam, the first skeleton 1, second skeleton 2, the 3rd skeleton 3, the 4th skeleton 4, the 5th skeleton 5, the 6th skeleton 6, the 7th skeleton 7, the 8th skeleton 8, pull head 9, pull head 91, pull head 92, pull head 12, guide post 10, guide post 101, guide pad 11, guide pad 111, pull bar 13, pedestal 14, pull bar 15, pull bar 16, pull bar 17, pull bar 19, pull bar 20, pull bar 21 and pull bar 22; Described second skeleton 2 is connected with the first skeleton 1 respectively with the 3rd skeleton 3 one end, and is also connected in the pull head 12 on pedestal respectively by pull bar 13 and pull bar 15; Described 4th skeleton 4 and the 5th skeleton 5 are respectively fixedly connected with guide pad 11 and to block 111; Described guide post 10 and guide post 101 respectively one end are inserted in guide pad 111 and guide pad 101, and the other end is fixed on pedestal; Described 6th skeleton 6 and the 7th skeleton 7 one end are connected with the 8th skeleton 8 respectively and are connected respectively by pull bar 22 and pull bar 21 with the pull head 92 be arranged on pedestal 14.
