Nut 11: select the M14 mountain type nut mated with standing screw 8.
The processing of the utility model bracing means, installation and use procedure:
The processing of each part in device:
Standing screw 8: screw rod reinforcing bar adopts toothless saw cutting die, by die head threading machine or screw die machining screw.The bar dowel of screw rod tail end fourth weldering requires vertical with screw rod, firm welding.Supporting steel pipe 9: outsourcing or lease, tests to steel pipe used, and its specification, quality should meet instructions for use and relevant criterion, and without the defect such as flexural deformation, crack.PVC sleeve pipe 7: be outsourcing, its specification, quality should meet use and standard-required.Weather strip 4: the self-adhesive foamed sealing joint strip of outsourcing, specification, quality should meet instructions for use and standard.Mountain type card 10: outsourcing or lease the mountain type card that mates with supporting steel pipe 9, its specification, quality should meet and use and standard-required, and free from flaw, distortion.Nut 11: the mountain type nut that outsourcing is mated with standing screw 8, require that quality meets standard, screw thread coordinates closely with screw rod screw thread, and not damaged.
Install and use:
Before installation, under concrete, screw hole is reserved on the top of wall 1a: during construction lower floor's wall, be located at by the Screw arbor with nut at both-ends on wall form top and be about 150mm absolute altitude place apart from soffit, transfer is about 500mm.Screw arbor with nut at both-ends is positioned at section within the walls and is installed on PVC sleeve pipe, and after dismounting Screw arbor with nut at both-ends, the PVC sleeve pipe be retained within the walls forms screw hole.Configuration upper walls (in Fig. 1 concrete wall 1) form surfacing: the template being positioned at through metope side is lengthened downwards along short transverse, the top pre-buried PVC sleeve pipe 7 centre distance+100mm of wall 1a under extension length=floor top to concrete, and the pre-buried PVC sleeve position of corresponding lower floor wall bores row Ф 18 hole on form surfacing.
The process of installing and dismantling:
At the side adhesive seal bar 4 at concrete slab 2 top;
Install upper walls template (it is positioned at through metope side template and extends to wall horizontal joint less than 3);
Inboard from lower floor's wall, the boring of aiming in wall top PVC sleeve pipe 7 and the downward template of upper walls penetrates standing screw 8, and the bar dowel 12 that standing screw 8 tail end fourth is welded is abutted against lower floor side within the walls;
Mountain type card, nut is inserted in the front end of standing screw 8;
Install supporting steel pipe 9, supporting steel pipe 9 is abutted in the outside of template lumps of wood back cord 6, its two supporting steel pipes 9 lay respectively at the upper and lower of standing screw 8 front end, are stuck in the groove of mountain type card 10, fastening nut after in place.
Reinforce after using, dismantle nut 11, mountain type card 10, supporting steel pipe 9, standing screw 8, then stripping panel 5 successively.
Compared with prior art, the main feature of this device is:
Adopt standing screw 8, supporting steel pipe 9 etc. wall horizontal joint position template and wall connecting of constructing to be fixed, template end opening can be prevented outer swollen.With the difference of counter screw shuttering: the standing screw of this device is used for template and anatomical connectivity, carry out support using structure as supporting mass to template to fix, stop template deformation displacement, and the Screw arbor with nut at both-ends usually adopted just carries out drawknot reinforcing to template itself, inner and outer template global displacement can not be prevented.
Concrete slab 2 side adhesive seal bar 4 below concrete wall horizontal joint 3 place, is reinforced by standing screw 8 pairs of form surfacings 5, reaches tightly seamless, can mortar leakage prevention effectively.Standing screw 8 as the rest of upper mould, can keep form stable simultaneously.Take in pre-buried PVC sleeve pipe 7 indwelling screw hole mode within the walls, standing screw 8 detachably reclaims turnover and uses, and saves and drops into.Utilize lower floor wall formwork screw hole that the standing screw of upper strata wall form is installed, need not apertured in addition, thus simplify operation, to save manually, material.Device simple structure, is adapted at job site processing.Wherein the former material of standing screw can utilizing works reinforcing bar leftover bits and pieces, thus reduces costs.
Although be described the utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; when not departing from the utility model aim, can also make a lot of distortion, these all belong within protection of the present utility model.
