Technical field
The utility model relates to a kind of building implements, particularly relates to a kind of reducing and reuses building reservation hole device.
Background technology
At present, the method for reserving the hole in the building trade mainly is: iron wire on iron nail, again the iron nail nail on template, with iron wire short tube is bound and to form the hole and reserve device, again flexible material such as injection yellow sand in the short tube.When adopting this method,, cause the location inaccurate because it is not enough and occur the displacement phenomenon easily to reserve the device bulk strength with iron wire and the fixing hole of iron nail.In addition, this method material recovery difficulty is big, not only causes man power and material's waste, and construction is caused greatly trouble, the progress of influence construction greatly.
Summary of the invention
Technical problem to be solved in the utility model is: overcome defective of the prior art, provide a kind of reducing simple, easy to operate, accurate positioning to reuse building and reserve the hole device.
For achieving the above object, the technical solution of the utility model is: a kind of reducing is reused building and is reserved the hole device, contain sleeve, fixed mechanism and template, the center that fixed mechanism in axial direction passes sleeve is fixed on sleeve on the template, the sleeve cover plate that is stamped suitable for reading, described fixed mechanism contains vertical bar, cross-arm, nut, horizontal circular ring and fixing hitcher, vertical bar lower end is passed behind the cross-arm and the center of horizontal circular ring is connected and fixed, be set with fixedly hitcher on the horizontal circular ring, fixedly the bottom of hitcher is fixed on the template, vertically on the bar nut is installed above the cross-arm, the upper edge radial direction of described sleeve has two grooves, cross-arm is placed in the groove, makes the cross-arm clamp sleeve by adjusting nut.The cover plate of sleeve placement suitable for reading is used to prevent that concrete falls in the sleeve when concreting.
This reducing is reused building and is reserved in the device of hole, and vertically the bar upper end is provided with handle, is convenient to install, and described handle is annular handle or hook-type handle or long handle shape handle.
This reducing is reused building and is reserved in the device of hole, have one group of cutting that is positioned on the concentric circles according to the size of reserving sleeve diameter on the cross-arm, cross-arm is placed in the sleeve groove suitable for reading, cutting that is complementary with sleeve diameter on the cross-arm and sleeve groove suitable for reading are stuck and fix, therefore can select the sleeve of different-diameter according to the diameter of reserving the hole, be stuck fixing with the big or small identical cutting of selected sleeve diameter and the cutting of sleeve on the cross-arm.
This reducing repeated use building is reserved in the device of hole, and sleeve is cylindrical or for conical, along slit of axis direction incision of sleeve, so that be convenient to construction when form removal, sleeve adopts the pvc pipe material.
This reducing is reused building and is reserved in the device of hole, and there is herringbone at the horizontal circular ring center, and vertically the lower end of bar and the center of herringbone are connected and fixed.
This reducing is reused building and is reserved in the device of hole, fixedly hitcher is the fixing hitcher of claws of a hawk shape, claws of a hawk shape fixedly has small circle ring in the hitcher upper end, and claws of a hawk shape fixedly hitcher is sleeved on horizontal circular ring by small circle ring, is set with fixedly hitcher of 3 claws of a hawk shapes on the horizontal circular ring.
When using this reducing to reuse building to reserve the hole device, 3 claws of a hawk shapes fixedly hitcher be placed on respectively in the hole of accomplishing fluently in advance on the template, the fastening sleeve of adjusting nut is put cover plate at last then.Carry out form removal when concrete strength reaches condition, because sleeve adopts the pvc pipe material, pvc pipe material itself and concrete have good detachment, along axis direction sleeve are cut again, can easily prize mould with special fixture during form removal and can damaged structure.
The beneficial effects of the utility model are:
1) simple in structure, be convenient to construction.
2) this device can reducing, has one group of cutting that is positioned on the concentric circles in the device on the cross-arm, when reserving the hole diameter not simultaneously, only needs to change sleeve, operates practical and convenient.
3) this device is convenient to dismounting, can reuse tens of time, can economical with materials, have certain economic benefits and environmental-protection function.
4) this device use three claws of a hawk shapes fixedly hitcher position, can in work progress, not be offset accurate positioning.

The specific embodiment
Embodiment 1: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, among the figure, 1 is vertical bar, 2 is nut, and 3 is cross-arm, and 4 is horizontal circular ring, 5 are the fixing hitcher of claws of a hawk shape, and 6 is the annular handle, and 7 is small circle ring, 8 is sleeve, 9 is cover plate, and 10 is herringbone, and 11 is template, 12 are cutting, and 13 is concrete.Vertically the top of bar 1 is equipped with nut 2, the center that the herringbone 10 of cross-arm 3 and horizontal circular ring 4 is passed in the lower end of vertical bar 1 is connected to a fixed, claws of a hawk shape fixedly small circle ring 7 and horizontal circular ring 4 the be nested load of hitcher 5 by its upper end connects, have one group of cutting 12 according to the size of reserving casing diameter on the cross-arm 3, all cuttings 12 are positioned on one group of concentric circles, sleeve 8 upper edge radial direction have two grooves, cross-arm 3 is placed in the groove of sleeve 8, the cutting 12 that is complementary with sleeve 8 diameters on the cross-arm 3 and the groove of sleeve 8 are stuck and fix, and make cross-arm 3 press sleeve 8 by adjusting nut 2.Cover plate 9 is placed on the suitable for reading of sleeve 8.Vertically the upper end of bar 1 has annular handle 6.Sleeve 8 adopts the pvc pipe material, and sleeve 8 is cylindrical, has cut off a slit along the axis direction of sleeve 8.
During construction, at first determine to determine the distance of pipeline center according to standard and drawing after wall column finally whitewashes thickness that according to drawing the center of circle is determined in the line location in conjunction with the Structural Engineer apart from wall and post; Determine three summits of equilateral triangle then according to the center of circle, the place, three summits of locating on template 11 with drill bit holes; Sleeve 8 is placed on reserved location, 3 claws of a hawk shapes fixedly hitcher 5 be placed in the hole that template 11 bored, the cutting 12 that is complementary with sleeve 8 diameters on the cross-arm 3 is placed in sleeve 8 groove radially, with hand vice clamp nut 2, make cross-arm 3 clamp sleeves 8 and make sleeve 8 fixing, again cover plate 9 is placed on the suitable for reading of sleeve 8, concrete 13 falls in the sleeve 8 when preventing to build; After reaching condition, concrete 13 intensity turn this device of dismantling successively around, because sleeve 8 adopts the pvc pipe material, itself has good detachment with concrete 13, and sleeve 8 in axial direction cuts again the slit, can easily prize mould with special fixture during form removal and can damaged structure.
