Description
Technical field
The present invention relates to the pouring technique field of concrete wall, especially a kind of callable internal stay casing tube.
Background technology
Any concrete wall is built Shi Douhui and is used the inner bracing strip controlling width of wall body and control the foundation to protect layer thickness of reinforcing bar in concrete.Its object is to concrete wall width of wall body in casting process can be effectively controlled, the elemental cap layer THICKNESS CONTROL of reinforcing bar in body of wall is in effective allowed band.Any form bracing system all can use Screw arbor with nut at both-ends in template support process, all can use sleeve pipe, wishing that its concrete and screw rod in concreting process are isolated when using Screw arbor with nut at both-ends, can remove screw rod recycling after having built.The method and the device that control width of wall body and thickness of protection tier adopt usually: cement inner bracing strip; But exist and easily destroy, the not easily problem such as fixing in template support process.
In template support, the sleeve pipe used during Screw arbor with nut at both-ends is used usually to adopt: common PVC pipe and bolt special sleeve pipe etc.; But exist after concreting completes and cannot take out sleeve pipe, waste material, the problems such as not reproducible utilization.
Summary of the invention
The object of the invention is to the defect for existing in above-mentioned prior art; a kind of recyclable internal stay casing tube is provided; control width of wall body when building for concrete wall and control reinforcing bar foundation to protect layer thickness in concrete, using in form work engineering during Screw arbor with nut at both-ends and itself and concrete can be made effectively to isolate.The present invention effectively can control width of wall body and reinforcing bar protective layer thickness in concrete, and Screw arbor with nut at both-ends and concrete can be made in form work engineering effectively to isolate.The present invention can reuse, and does not produce building waste, accomplishes energy-saving and environmental protection and civilized construction.
The present invention is achieved by following technical solution: a kind of callable internal stay casing tube, comprise internal stay casing tube chock plug and the main footpath of internal stay casing tube, two, internal stay casing tube main footpath respectively connects an internal stay casing tube chock plug, be provided with in the two ends of internal stay casing tube main footpath and frustrate platform, internal stay casing tube chock plug is connected by frustrating platform, frustrate platform to be connected footpath with internal stay casing tube chock plug and to connect, internal stay casing tube chock plug is provided with keyhole, and described keyhole is T-shaped torsion 90 ° of dismounting types; In template support, two, main for internal stay casing tube footpath is respectively connected an internal stay casing tube chock plug and be combined into internal stay casing tube, in use Screw arbor with nut at both-ends position, internal stay casing tube and wall steel bar are fixed in internal stay casing tube chock plug position, Screw arbor with nut at both-ends passes in the middle of internal stay casing tube, carries out concreting; Treat that concreting completes, after form removable, keyhole is inserted with T-shaped key bit, half-twist is removed handle end at key and is pulled at, take out internal stay casing tube chock plug, main for internal stay casing tube footpath is removed in the main footpath microcephaly of bar insertion internal stay casing tube to withstand after internal stay casing tube chock plug takes out and frustrate platform, remove the bar other end with the knocking main footpath of internal stay casing tube and namely remove the main footpath of internal stay casing tube.
Preferably, described internal stay casing tube chock plug and the main footpath of internal stay casing tube adopt rigid PVC material to process.
Preferably, the main footpath of described internal stay casing tube and internal stay casing tube chock plug are concentric reducer design size, internal stay casing tube main footpath top diameter 24.5mm, diameter at butt end 30mm, the main path length of internal stay casing tube is respectively 110mm, 160mm, 210mm, 260mm or 310mm, and two, internal stay casing tube main footpath wall thickness is different, microcephaly is thinner than major part, microcephaly's wall thickness 2mm, major part is according to the change of model difference, and internal stay casing tube main footpath hollow diameters is 16.5mm; Describedly frustrate the wide 2mm of platform, high 15mm; The long 35mm of described internal stay casing tube chock plug, connects footpath by internal stay casing tube and chock plug end forms, top diameter 30mm, diameter at butt end 35mm, hollow diameters 16.5mm; Described internal stay casing tube chock plug connects path length 15mm, wide 20.5mm, wall thickness 2mm, hollow diameters 16.5mm.
Preferably, the main footpath of described internal stay casing tube is removed bar and is adopted rod or steel bar.
Preferably, shank diameter is removed in the main footpath of described internal stay casing tube is 17 ~ 18mm.
Described internal stay casing tube and wall steel bar are fixed at No. 22 iron wires in internal stay casing tube chock plug (1) position.
The technique effect of technical solution of the present invention is as follows:
1,internal stay casing tube effectively can control width of wall body when concrete wall is built and control reinforcing bar foundation to protect layer thickness in concrete, internal stay casing tube had both played the effect of inner bracing strip, in form work engineering, make Screw arbor with nut at both-ends and concrete isolate, play the effect of sleeve pipe simultaneously;
2, internal stay casing tube adopts rigid PVC material to process, and is combinationally used by the main footpath of sleeve pipe and thimble plug head;
3, the main footpath of sleeve pipe and sleeve pipe chock plug be concentric reducer be convenient to remove recycling;
4, establish in the main footpath of sleeve pipe and frustrate platform, reduce the damage to the main footpath of sleeve pipe when removing, increase recycling number of times;
5, sleeve pipe chock plug is for convenience of the T-shaped keyhole removed, and it is convenient to remove, and weares and teares less, adds and reuse number of times;
6, internal stay casing tube model variation, be applicable to various width body of wall, different model internal stay casing tube, internal stay casing tube chock plug is general, and internal stay casing tube concentric reducer is general, and unique difference is that the length in the main footpath of internal stay casing tube is different according to the demand of different body of wall; Internal stay casing tube has 150mm, 200mm, 250mm, 300mm, 350mm type usually.
