Abstract
The utility model discloses a mould in structural slab embedded plate hole, its characteristics include tube core, sheath and filler, the tube core is formed by the pipe intercepting, the tube -shape body that the sheath formed for the sheet iron curls, its tube -shape body radially be equipped with one at least bead, the bead is equipped with several incisions on the circumference, pack to netted steel wire, the sheath parcel is on the tube core outer wall, in the bead of locating the sheath that packs and between the outer wall of tube core. The utility model discloses after structural slab reinforcement accomplishes, directly set up on the check point of structural slab, wait to examine time measuring, demolish the utility model discloses obtaining the detect process hole promptly, having simple structure, the preparation is convenient, neither influences the quality of structural slab, the shutoff of the fabrication hole of being convenient for again.
Description
Technical field
The utility model relates to building operations and detection technique field, especially a kind of mould of structural slab embedded board hole.
Background technology
In civilian construction construction, before carrying out agent structure examination, to survey the thickness of slab of structural slab.Prior art constructor adopts electric drill to implement to abolish method to structural slab, namely the fabrication hole of a diameter 2 ~ 4 centimetres is got out, surveyed by the thickness of fabrication hole to structural slab local, Problems existing is, this detection method wastes time and energy, and when boring procedure runs into reinforcing bar, position of remapping is bored again, both cause the damage of bar construction, affected the presentation quality of structural slab, and be not easy to the shutoff of fabrication hole.
Utility model content
The purpose of this utility model is the mould in a kind of structural slab embedded board hole provided for the deficiencies in the prior art, the utility model is after structural slab reinforcing bar binding completes, be set directly on the test point of structural slab, time to be detected, remove the utility model and namely obtain characterization processes hole, there is structure simple, easy to make, neither affect the quality of structural slab, be convenient to again the shutoff of fabrication hole.
The concrete technical scheme realizing the utility model object is:
The mould in structural slab embedded board hole, its feature comprises tube core, sheath and filler, and described tube core is intercepted by pipe and forms, sheath is the cylindrical body that sheet iron is curling, the radial direction of its cylindrical body is provided with at least one fin, and fin is circumferentially provided with several otch, and filler is meshy steel wire; Described sheath is wrapped on tube core outer wall, in the fin that sheath is located at by filler and between the outer wall of tube core.
The utility model, after structural slab reinforcing bar binding completes, is set directly on the test point of structural slab, time to be detected, remove the utility model and namely obtain characterization processes hole, there is structure simple, easy to make, neither affect the quality of structural slab, be convenient to again the shutoff of fabrication hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the deployed configuration schematic diagram of the utility model sheath;
Fig. 4 is using state schematic diagram of the present utility model.
Detailed description of the invention
Consult Fig. 1, Fig. 2, Fig. 3, the utility model comprises tube core 1, sheath 2 and filler 3, described tube core 1 is intercepted by pipe and forms, sheath 2 is the cylindrical body that sheet iron is curling, the radial direction of its cylindrical body is provided with at least one fin 22, fin 22 is circumferentially provided with several otch 21, and filler 3 is meshy steel wire; Described sheath 2 is wrapped on tube core 1 outer wall, in the fin 22 that sheath 2 is located at by filler 3 and between the outer wall of tube core 1.
The utility model uses like this:
Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, after structural slab reinforcing bar binding completes, before concreting, each test point the utility model being set directly at structural slab is fixed with structural slab reinforcing bar 4 colligation, and make tube core 1, upper plane that sheath 2 exposes structural slab, treat concreting, maintenance completes, when structural slab is detected, remove the utility model and namely obtain characterization processes hole.
Dismounting of the present utility model
Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, first, tube core 1 is extracted in sheath 2, secondly, take out the filler 3 be loaded in sheath 2 fin 22 and between tube core 1 outer wall, finally, the position that sheath 2 exposes structural slab is clamped with pliers, outside one drag and sheath 2 can be extracted out in structural slab vertically, its extraction is analyzed as follows, one is because sheath 2 is the curling cylindrical body being wrapped in tube core 1 outer wall of sheet iron, the cylindrical body of sheath 2 is not closed vertically, under the effect of external force, cylindrical body can be closed up by natural shrinking, two be due to cylindrical body radial direction arrange fin 22 circumferentially on be provided with several otch 21, under the effect of external force, cylindrical body radial direction is subject to the extruding of structural slab, make cylindrical body under the double action of pulling force and extruding force, the prismatic of fin 22 is stretched, several otch 21 that fin 22 is arranged radially draws in, so sheath 2 is removed by fast dismantling, and on structural slab, remain the characterization processes hole with annular groove, can implement to survey the thickness of slab of structural slab.
The shutoff of fabrication hole on structural slab
Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, because the radial direction of the utility model sheath 2 cylindrical body is provided with twice fin 22, after the utility model is removed in structural slab, due to the setting of fin 22, structural slab remains the characterization processes hole with annular groove, when implementing shutoff to the fabrication hole on structural slab, annular groove is exactly the seal groove in fabrication hole, the antiseep difficult problem that effective guarantee fabrication hole is set of seal groove, concrete shutoff process is as follows, after completing the actual measurement to the whole test point of structural slab, after supervising engineer's acceptance(check), prepare to implement shutoff to fabrication hole.Before shutoff, in the annular groove first in fabrication hole bottom structural slab, gauze wire cloth is set, by the hole dabbing in concrete technology hole, and evacuation concrete is cleaned out, with the moistening fabrication hole periphery of water, then fabrication hole inwall brush plain-water slurry one time, water with C35 microdilatancy water-tight concrete, pouring limit, limit iron staff vibrates gently, until pouring strikes off with plane on structural slab, surface is rubbed with the hands flat with wood, with covering with ground sheeting, prevent moisture from evaporating rapidly, and mark is set.After spending 24 hours, start maintenance, curing time is no less than 7 days, and on structural slab, the shutoff of fabrication hole completes.
Adopt the utility model to after the shutoff of fabrication hole completes on structural slab, the concrete of pouring defines sealing ring in the annular groove of fabrication hole, serves the antiseep effect of fabrication hole.
The utility model not only solves and arrange characterization processes hole problem on structural slab, but also guarantee is provided to effective shutoff of fabrication hole, on the basis meeting structural slab monitoring technique, achieve the quality neither affecting structural slab, be convenient to again effective shutoff of fabrication hole.
