The prefabricated large-scale occupation for turning round king's block steel form and removing operating efficiency, reducing engineering investment cost, enhance operating environment in construction site
All various aspects such as healthy and safe accordance show unique advantage.
The present invention is to solve above-mentioned technical problem by following technical proposals：A kind of prefabricated torsion king block demoulding method,
It is characterized in that, it includes step used below：
Step 1：It is prepared work, is carrying out first being ready to need the tool of demoulding in advance when demoulding work；
Step 2：Splice mobile crowbar, mobile crowbar selects the round steel one meter five long, diameter is 25 millimeters；
Step 3：Aperture, to the round hole for opening 15 centimetres or so in the middle part of torsion king's block steel form；
Step 4：Polishing circular hole, needs the circular hole of split mistake to polish, and polishes smooth, is smooth sealing steel plate inner wall；
Step 5：Start demoulding work, staff begins to use hydraulic jack, mobile crowbar to start to work；
Step 6：It deals with problems arising from an accident, packs up sweep scene after the completion.
Preferably, need the basic holding of three people operation is synchronous to carry out during the progress striking job.
Preferably, the hydraulic jack selects the screw jack that top power is five tons.
Preferably, steel form top two sides are equipped with overturning-preventing pull rod made of long 500 millimeters of zinc-plated screw rod.
The positive effect of the present invention is that：The present invention can combine live site condition well, be able to satisfy all kinds of big
Type turns round the dismounting operation of the fast prefabricated steel-template of king, and adaptability is stronger, and structure is simple, making material saves, low manufacture cost, protects
It supports and goes along with sb. to guard him also convenient and easy, there is extraordinary economy and practicability, construction site is prefabricated large-scale to turn round king's block steel to improve
Form removable operating efficiency reduces all various aspects such as engineering investment cost, the career safety & health accordance for enhancing operating environment
Show unique advantage.

Specific embodiment
Present pre-ferred embodiments are provided with reference to the accompanying drawing, in order to explain the technical scheme of the invention in detail.
As shown in Figures 1 to 6, the prefabricated torsion king block demoulding method of the present invention includes step used below：
Step 1：It is prepared work, is carrying out first being ready to need the tool of demoulding, including hydraulic thousand in advance when demoulding work
The tools such as jin top, mobile two sets of crowbar, safety rope, limit pull rod, save the time for next work；
Step 2：Splice mobile crowbar, mobile crowbar selects the round steel one meter five long, diameter is 25 millimeters, a conduct
Manipulator's lever, other end bending, bends 250 millimeters of segment length, and cross bar, the weldering of cross bar both ends are welded in portion position in this paragraph
Meet each one, bearing of 62 millimeters of outer diameter of installation, and with electric weld handle bearing inner ring and round steel contact surface firm welding, and it is preceding
Face round steel is welded into trolley form, and bending segment end is made into flat form, and crowbar mobile in this way can agitate more at work
Heavy article can also realize planar movement in agitating shuttering work state, the working efficiency of demoulding can be improved；
Step 3：Aperture, to the round hole for opening 15 centimetres or so in the middle part of king's block steel form is turned round, the hole is when template is installed with slightly
Big circular seal steel plate blocks, and back is by the fastening of wooden wedge choker block, and the circular hole is by the installation site as jack；
Step 4：Polishing circular hole, needs the circular hole of split mistake to polish, and polishes smooth, is smooth sealing steel plate inner wall, hairless
The defects of thorn, pit slot, as steel form material, inner wall surface thereof quality also requires on an equal basis, which constantly seals in casting concrete
Blocking is closed, changes plate to need to remove the circular hole before demoulding, exposes and turn round king's block concrete face, the circular hole by polishing can allow hydraulic
The work of jack becomes more convenient；
Step 5：Start demoulding work, staff begins to use hydraulic jack, mobile crowbar to start to work, first removes top
Upper workbench railing, then the clamping screw between template is loosened, fix overturn-preventing stay-bolt.After the completion of preparation, by
Edge sealing under template to be removed is filled at the tip position that two people hold mobile crowbar respectively, and in addition a people installs jack, by thousand
Jin top is installed by circular hole, and slowly operation jack jacks outward, meanwhile, mobile crowbar firmly sled top upwards, and exert oneself to
Outer drawing moves crowbar handle, and when above-mentioned jack is with mobile crowbar collective effect, holding is coordinated, is synchronous, slowly removes punching block in this way
It after distance reaches 20 centimetres or so between plate, then unscrews overturning-preventing rod nut to the end, repeats above-mentioned mobile crowbar and thousand
Jin top operation sequence, can safely and fast loosen steel form in this way, move to free state, improve work by operating repeatedly
Make efficiency；
Step 6：It deals with problems arising from an accident, all unlocks overturning-preventing pull rod device, hung by loop wheel machine and move on to designated position and polished, removed
The road Zha Dengxia treatment process, packs up sweep scene after the completion.
It carries out needing the basic holding of three people operation is synchronous to carry out during striking job, it is ensured that template safety and steady is torn open
It removes.
Hydraulic jack selects the screw jack that top power is five tons, and the work of such hydraulic jack can become more
It is convenient.
Steel form top two sides are equipped with overturning-preventing pull rod made of long 500 millimeters of zinc-plated screw rod, and protection staff is more
Add safety.
In conclusion the present invention can combine live site condition well, it is able to satisfy all kinds of large-scale torsion kings prefabricated punching block fastly
The dismounting operation of plate, adaptability is stronger, and structure is simple, making material saves, low manufacture cost, maintains and goes along with sb. to guard him and also facilitates province
Thing has extraordinary economy and practicability, for improve construction site it is prefabricated it is large-scale turn round king's block steel form remove operating efficiency,
It reduces all various aspects such as engineering investment cost, the career safety & health accordance for enhancing operating environment and shows unique advantage.
Particular embodiments described above, the technical issues of to solution of the invention, technical scheme and beneficial effects carry out
It is further described, it should be understood that the above is only a specific embodiment of the present invention, is not limited to
The present invention, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in this
Within the protection scope of invention.
