Step by step length tight
Detailed step by step tight size chart
Suitable for specific parts apply to construction of engineering models
60cm application of ring beam reinforced 30cm beam
70cm suitable for brick and frame 30-35cm constructional columns
80cm brick and frame 40-45cm of structural column
90cm brick pillars and frame 50-55cm
100cm brick pillars and frame 60-65cm
110cm applies to plants and tall buildings 70cm the framework of pillar
120cm applies to plants and tall buildings 75-80cm the framework of pillar
Specific calculation methods are as follows:
Example: 40cm structural columns template + 5 cm (sides 2.5cm) + timber 20cm (10cm on both sides) recommended type 80cm = 65cm and so on
(Remind the user 40cm posts don't have wood as direct reinforcement)
Spacing between the layers of constructional column description
Pillar model interval distance
30—45cm 40cm
50-55cm more than 1.5 30cm
Under 1.5 40cm
60—65cm 30cm
65cm some of these logs are recommended methods
1, and clips encryption law: 65cm above of big pillars to special note bottom of reinforcement (is 1.5 m following), by general operation 1.5cm following spacing should for 30cm, now due to pillars too big should to 15cm a spacing, more with of this layer on called encryption, encryption of this layer can in pillars poured finished 2 hours voting at the demolition, used to reinforcement other of pillars, this on called encryption law.
2, mixed method: according to workers using empirical methods
(1) step by step and tight
Butterflybuckle combination. (2) step by step and tight triangle fastener combination. (3) step by step tightening and tube combination. (4) step by step tight polo bar combination. Note: Although some fasteners disadvantage a lot up for elimination, but combine and step by step close combat posts more useful.
2 step by step making tight editing
Formwork system is developing rapidly, currently used, combined steel formwork, assembly-type sliding formwork, climbing formwork, templates, template to the high degree of mechanization development. But according to the project's characteristics, construction technology, formwork in construction of small technology, allows us to learn from each other, according to local conditions. For example, my company's woodwork master set when the template is just like using a very lightweight, practical "step by step the bear" with clamp the template.
Template fixed-there are a lot of ways, traditional construction methods commonly 8th wire bending, wooden poles, steel traps, as well as
steel, welded steel pipe adjustable stationary jigs or fixtures, and so on. When used in these types of articles, using a large number of nails, expensive, and wood can easily be damaged, wasted the greater need for leasing large amounts of steel pipes, fasteners, and must-have accessories such as wedges, bolts or steel rod, turnover is less time-consuming. And that their use is narrow, fastening is ineffective, is limited to one or two types of concrete formwork supporting, not interchangeable, custody is not convenient, and slow pace of construction, increased construction costs.
Our woodwork teacher compared from Shandong has introduced this "step by step the bear" steel template card, after many years of use, we believe that in many respects it has other templates located incomparable advantages, and used it to master some usage and experience.
This steel using high quality rail steel forging, and strength, and snaps at once, not only substantial reliable, flexible, easy to use, labor efficiency, high turnover rate, and style lightweight and beautiful, safe deposit. This clips adaptable and frame beam, girder, Wale is available, short columns, independent columns, structural columns, concrete formwork can be used, such as capping, and Assembly and disassembly, construction speed, easy to use.
"Step by step the bear" steel template based upon length, there are 70 cm, 80 cm, 90 cm, 100 cm measure, this template, clip, and site production costs of less than 9 million. Produced by the factory, cost reducing, and available for re-use, the damage rate is extremely low.
"Step by step the bear" templates, clip, hook-shaped rod and made up of active head restraints. Hooked flat card bar 30mmx6mm steel, rail steel for active head restraints by oven wrought made, its size and shape as shown in Figure 1. Cards, cards after they were done, put them together will be able to use.
Clips when using template wooden rod with hook a hook one side, then with a small hammer to rod hook end striking the lower part of the active head restraints, until tight. Due to active head restraints between holes and gaps are small, with self-locking ability, and that any such self-locking ability to resist stress resulting from expansion of template.
"Step by step the bear" fixtures removed the template, just no hook with a small hammer to rod end striking the lower part of the active head restraints, vibration and impact hammers-elastic loose, they can take off clips. Fixtures, demolition, qiaojin, percussion fixtures do not use brute force, prevent fixture it knocked on more urgent. After finishing his work along the rod to slide into the active head restraints with hook side over a bale, cover good or stacked on the specified for the library, so that next time the formwork re-use.
After use, we have found that this fixture in use should be aware of the following issues:
End 1, active head restraints must be used with wood, not with hard materials (such as steel) is used prevent fixture not clamping.
2, due to our limitations, "step by step the bear" templates should use jigs maximum effective range is less than 80 cm formwork and reinforcement.
3, the "step by step the bear" template fixtures set has been completed, may not be on top of fixture Stampede, preventing the clamp loose security caused by accident or clamps loose heaving caused by mold.
4, use should be done "step by step close" custody. Clips due to the small size, light weight, if it does not do the custody work, very easy to lose. Active head restraints parts are easily lost. Hook-shaped pole after having penetrated the active head restraints, should be in the hook-shaped tail covered electrodes for welding into a snare drum, or wearing a 4 mm hole, screw on the bolts, active head restraints do not take off the lost.
5, clamp removed, should specify the location stack and pay attention to moisture, prevents corrosion.
