Preferably, shoes 7 are mounted on the end of two support bars 6, wherein support bars 6 are horizontal and another support bar is located on the upper side.
The construction method of the structure comprises the following steps:
step of paying off
After the platform bottom template 1 is erected, a template supporting line and a control datum line are released on the template by taking the center of the hole as a circular point. Wherein the distance between the control datum line and the support formwork line is equal to the thickness of the inner side formwork plus the thickness of the support batten.
The second step is that: setting a positioning plate
And correspondingly fixing the same number of positioning plates 9 on the platform bottom template 1 along the control datum line according to the distance and the number of the designed support battens 4. When the positioning plate is fixed, the front end part of the positioning plate 9 is opposite to the datum line, the positioning plate 9 is made of common battens (wood templates or multi-layer plates), the size is about 120 mm by 250mm, and the thickness is larger than 20 mm.
The third step: inside form closure
The supporting battens 4 are vertically fixed on the bottom template 1, the inner sides of the bottoms of the supporting battens 4 tightly push against the positioning plate 9, and the outer sides of the supporting battens 4 are provided with the inner side templates 3 in a supporting mode and are sealed.
The fourth step: transverse back edge arrangement
An upper group of transverse steel bar back edges and a lower group of transverse steel bar back edges 8 are arranged in the supporting battens 4, each group of back edges is made of two rows of steel bars, oppositely-pulling screw rods penetrate out from the middle of the two rows of steel discs, and the 3-shaped clamps are arranged at the ends of the back edges and lock the steel bar back edges towards the direction of the template.
When single reinforcing bar is not enough circles week length, can adopt overlap joint or welding mode extension the screw-thread steel is preferred to the reinforcing bar, two more than the diameter >20mm are groups, can adopt four to be groups when the diameter <18mm, the effect is better when adopting the welding or butt joint.
The fifth step: providing a support system
The central position of the opening is provided with a vertical rod 5, a supporting rod 6 is arranged on the vertical rod, the supporting rod 6 is arranged in a symmetrical mode by taking the vertical rod 5 as an axial center, a moving support 7 is arranged at the outer end of the supporting rod 6, the moving support 7 is buckled on a steel bar back edge 8, and the length of an adjusting screw rod 71 is used for outwards supporting the steel bar back edge 8.
The front end of the support rod 6 is clamped and fixed by the support 7, and the stress is uniform, so that the rigidity is increased. The more the number of the floating supports 7 is, the more uniform the supporting tops of the templates are, and the number of the floating supports is increased or decreased according to the thickness of the platform plate. For example, if the diameter of the silo opening is 10 meters, the thickness of the platform plate is 1-1.2 meters, and 8 floating supports are arranged. If the diameter of the constructed silo opening is more than 12 meters, and the thickness of the platform plate is 1.2-1.5 meters, 12 floating supports can be arranged, and the symmetrical and uniform arrangement is also ensured.
The trip holds in the palm the strong point of template promptly, and the bracing piece is the support arm, the utility model designs a support trips simultaneously with 2 or 3 support arms jointly and hold in the palm.
The utility model provides a silo inner formword is strutted the scheme and is dual, be the foundation outside the holding power to the taut template of stay bolt, be the support arm top supporting power at the center of foundation.
For example, the original construction of silo openings with the diameter of 10 meters and the platform thickness of 1-1.2 meters needs to arrange at least 20 counter bolts to meet the requirement of supporting strength, and the supporting effect is obviously superior to that of 20 counter bolts, so that the openings of the platform are effectively protected from deformation when concrete is poured.
In addition, when the size of the corner structure of the platform is larger, the number of the split bolts can be properly increased to achieve the purpose of reinforcement.
The above components are not limited to manufacturing materials and specifications, and the structure manufactured or used according to the utility model belongs to the protection scope of the scheme.
The utility model has the beneficial effects of 1, reduce the use amount of a large amount of split bolts, reduce material consumption, improve construction speed, 2, from single template split reinforcement mode optimization for split and the dual mode of consolidating and combining together of roof pressure, the fulcrum position can be adjusted at any time or increase and decrease, the template atress is even reasonable, the protection effect improves and is showing, 3, in the aspect of the construction operation on the platform, can realize through the trip support that the template props up the size fine setting, 4, evenly set up the locating plate on the bottom plate, the atress more tends to rationally from structure itself from top to bottom, also play the reinforcement to the roof pressure simultaneously.
