Description
Technical field
The present invention relates to Equipment Foundations and reserve the job practices of circular anchor (bolt) hole.
Background technology
In the Equipment Foundations construction, need the anchor (bolt) hole of reservation equipment on the concrete foundation, the general employing of its method for obligating installs corrugated steel pipe, plastic pipe and perhaps installs methods such as wooden form, treats in time to remove after the concrete setting.Corrugated steel pipe adopts a termination band draw-in groove, and the instrument of other end headband handle is clamped corrugated steel pipe with draw-in groove, successively peels off dismounting, and the dismounting effect is undesirable; Plastic pipe adopts high-temperature baking, makes its deliquescing, and integral body is extracted then, and its method causes the plastic pipe dialysis sometimes, directly influences the intensity of the back-grouting of anchor (bolt) hole; Wooden form adopts big down young rectangular pyramid shape tub structure suitable for reading, and it is little to install the cross section, and firmly all difficulties such as difficulty, limited space system can appear in the hole that the degree of depth is darker when removing.In order to improve the resistance to plucking supporting capacity of bolt, often adopt end opening slightly than big structure suitable for reading, corrugated steel pipe and plastic pipe are standard material, can't satisfy, and go up the big rectangular pyramid shape tub of young end opening and promptly enable to satisfy dimensional requirement, also can't remove.That is: the characteristics of anchor (bolt) hole are the big long and narrow spaces of draw ratio, therefore dismounting are brought great inconvenience, and its template all can not be reused in demolishing process again.
Summary of the invention
The object of the present invention is to provide a kind of Equipment Foundations to reserve the job practices of circular anchor (bolt) hole, this method is simple to operate, form removal is fast, and this mould is reusable.
For realizing above-mentioned purpose, the present invention adopts following technical scheme: Equipment Foundations are reserved the job practices of circular anchor (bolt) hole, it is characterized in that it comprises the steps:

The 4th step, dismounting mould: after concrete pouring finishes, get final product the steel pipe or the flitch of the top reinforcing in the stripping and the outside of the plate of squeegeeing, and in time carry out the leveling of surface of base; When treating concrete initial set, extract the plate 17 of squeegeeing out, the twisting handle makes between plastic sheeting and the concrete of template protection layer and gets into air; Before final set, unclamp first setscrew nut 10, the 3rd setscrew nut 12, lift the first slidable adjustment seat 3, the second slidable adjustment seat 4; Make the distance between the first slidable adjustment seat 3 and second holder elongated, the distance between the second slidable adjustment seat 4 and first holder is elongated, and 4 15 of templates surround columniform diameter and just diminish; Rotary handle 1 makes base plate 18 separate with central axis 2, extracts template; Lift base plate 18, stay a circular hole hole (cylindrical hole); At this moment, come off when the initial set as the cement paste of the plastic sheeting of the topping of template and concrete surface in the circular hole hole, be convenient to cleaning;
The 5th step, cleaning hole:, and garbage-cleaning in the hole is clean with cleek with the concrete surface plucking in the circular hole hole, again hole is sealed, obtain Equipment Foundations and reserve circular anchor (bolt) hole.
In the present embodiment, handle 1 adopts round steel to make with central axis 2, and handle 1 is welded into " T " font with an end of central axis 2; The middle part of central axis 2 is welded with first holder 7, is welded with second holder 9 apart from lower end 300mm place; The top of central axis is processed with screw thread (external screw thread) between first holder 7, so that first setscrew nut 10, second setscrew nut 11, the 3rd setscrew nut 12 and the 4th setscrew nut 13 are installed; The lower end of central axis is processed with screw thread (external screw thread), so that be connected with base plate 18;
Empty somewhat larger in diameter was about the pipe of 40mm in central axis 2 in the first slidable adjustment seat 3, the second slidable adjustment seat 4 and the 3rd slidable adjustment seat 8 all adopted, and located to be welded with steel plate 0 °, 90 °, 180 ° and 270 ° of pipe; One end of steel plate is drilled with the hole, so that hinged with movable link rod 5; Distance between slidable adjustment seat and the holder shortens, and the columniform diameter that 4 templates 15 and 4 plates 17 of squeegeeing are surrounded just becomes big; Distance between slidable adjustment seat and the holder is elongated, and the columniform diameter that 4 templates 15 and 4 plates 17 of squeegeeing are surrounded just diminishes;
Connecting rod 14 adopts diameter 8mm round steel to make, and is shaped as " [" type; " [" type round steel has two, and two ends is connected with the first slidable adjustment seat 3, the 3rd slidable adjustment seat 8 respectively, forms an integral body, so that when adjusting the first slidable adjustment seat 3, the 3rd slidable adjustment seat 8 moves together for this;
Template bearing 16 adopts the band steel of thick 6mm to make, and an end is welded on the steel square plane of template 15, and the other end is drilled with the hole, so that hinged with movable link rod 5; Be welded with two template bearings 16 on the steel square plane of each template 15;
The plate 17 of squeegeeing is four, and each is welded into the T font by two block plates, so that a straight flange is inserted in four slits of the cylindrical template that four templates 15 form; The steel plate that the plate 17 of squeegeeing contacts with template surface should be processed into cambered surface, makes it can be close to template surface; The squeegee upper end of plate 17 is porose, lifts hook so that install when removing;
Application example shows: in the Equipment Foundations construction; When needing the circular anchor (bolt) hole of reservation equipment on the concrete foundation, adopted method of the present invention after, can accomplish installing and removing of template flexibly, fast; Can realize big young down, the reservation of going up the cylindrical equipment anchor (bolt) hole of the big or straight barrel structure of young end opening suitable for reading; Help improving the resistance to plucking supporting capacity of bolt, alleviated hand labor intensity greatly, template can be reused; Reduced construction cost, explained that method effect of the present invention is remarkable.
More than explanation is merely application implementation example of the present invention, can not limit the present invention's interest field certainly with this, therefore changes according to the equivalence that claim of the present invention is done, and still belongs to protection scope of the present invention.
