Abstract
The utility model discloses a concrete thickness control measurer for a cast-in-place floorslab. The control measurer comprises a substrate, a plurality of measuring rods and a handrail, wherein the substrate is a flat plate; the measuring rods are arranged below the substrate, are fixed to the lower surface of the substrate and are perpendicular to the substrate; the lengths of the measuring rods are the same; the handrail is arranged on the upper surface of the substrate and is fixed with the substrate; and fluorescent paint is coated on the surface of the handrail. According to the control measurer, the measuring rods of which the heights are equal to the thickness of the concrete detect whether the thickness of the concrete reaches the standard or not, the control measurer is put on a lower die plate directly during the placement of the concrete, and a substrate surface can be used as a thickness reference plane of a cast-in-place floorslab, so that the control measurer is used visually and clearly, and the thickness is measured conveniently and quickly; and the fluorescent paint is coated on the surface of the handrail, so that the control measurer is suitable for pouring and smashing operation at night or under the condition of poor light rays.
Description
Technical field
The utility model relates to a kind of survey tool, refers more particularly to the thick control survey device of a kind of cast-in-situ floor concrete easy to use.
Background technology
The control of floorslab concrete thickness of slab; Directly have influence on thickness of protection tier; And then have influence on concrete durability, and the primary approach of raising concrete structure durability is exactly the density that increases concrete material self, and increase concrete cover to reinforcement thickness; So just can stop the intrusion of moisture, carbon dioxide and harmful chemical, and delay the time that it arrives reinforcement location.
In practice of construction; Plate steel bar stress protective layer thickness has ± allowable variation of 3mm; Add sectional dimension+8; The too small situation of protective layer thickness of plate face reinforcing bar appears in the influence of-5 surface finish 8mm allowable variations easily, causes the concrete surface phenomenon that tangible corrosion of steel bar and concrete ftracture along muscle to occur.
Secondly, thickness of slab is the principal element that has influence on the concrete actual amount, concerning unit in charge of construction, concrete amount how much be directly connected to its economic interests, therefore, do not note just occurring easily the thickness of slab minus deviation phenomenon that exceeds standard in the site operation process slightly.
Several kinds of control methods below general employing the in management process in the past:
1, water smash before, copy 50 lines usually and to the post muscle, (paint and mark), draw 2 points with wide line during pour concrete, wide line is to the plate face, the discrepancy in elevation is the 50 centimeters absolute altitudes that just can control a line, needs only and on reinforcing bar, copies abundant point, promptly can control panel face absolute altitude.Also can directly measure 50cm up and down from the post muscle controls;
2, to the wall column gap ratio be not easy to more greatly to locate, the structure of backguy, can be welded in the steel bar end point and control absolute altitude (steel bar end is fit to do into L shaped downhand welding on the plate muscle) on the plate muscle.
3, can make root reinforcing bar hammer drill and insert concrete.This situation requires will keep vertical with the plate face when pricking down, confirm to prick the template face.
Said method all needs other station personnel nearby to operate in watering the process of smashing, and especially when carrying on construction work at night, surveys very inconvenience, lets the constructor go to survey not quite relieved again.
Chinese patent ZL200820106261.1, name is called the utility model patent of the thick inspection chi of cast-in-situ reinforced concrete slab; A kind of instrument of measuring thickness of slab is disclosed; Be made up of blade, absolute altitude chi, blade is a stock, and sharp-pointed front end is arranged; Absolute altitude chi and blade are perpendicular, and absolute altitude chi and blade are adjustable sliding connection; One end of absolute altitude chi has sliding sleeve, and the internal diameter of sliding sleeve and the external diameter of blade are complementary, and in the side of sliding sleeve positioning screw hole are arranged; Be rotary with positioning bolt in the positioning screw hole, this inspection chi, the thickness of the fluid concrete height of absolute altitude chi in advance as required; Be fixed after adjustment absolute altitude chi puts in place, insert in the cast-in-situ concrete of examine, know promptly whether the thickness of cast reaches requirement; But because the inspection chi is still similar with the measuring method that reinforcing bar directly inserts in the concrete with employing, the inspection chi is difficult for fixing in operation, the bad control of verticality; And the testing staff still needs operation nearby, has brought certain inconvenience to detection.
The utility model content
The utility model solves mainly that common inspection chi is difficult for fixing, the bad control of verticality and the testing staff needs the technical problem of operation nearby; Provide a kind of and can directly be placed on the Cast-in-place concrete scope of operation, do not need the testing staff nearby to measure and again can be as the thick control survey device of cast-in-situ floor concrete of the fixed thick control of Cast-in-place concrete thickness.
In order to solve the technical problem of above-mentioned existence, the utility model mainly is to adopt following technical proposals:
The thick control survey device of the cast-in-situ floor concrete of the utility model comprises that substrate, some survey rod and handrail, and said substrate be dull and stereotyped, and said survey is excellent to be located at the below of substrate and to fix with base lower surface; Survey rod all perpendicular to substrate, survey excellent identical length together, said handrail is located at the upper surface of substrate and fixes with substrate; Etc. excellent setting of many high surveys the control survey device is placed firmly, convenient measurement and flexible, substrate can remain level in the pouring operation; The measurement accuracy is high, and simultaneously, the control survey device is intuitively eye-catching to the thick fixed high observation of concrete in watering the process of smashing; Make the site operation personnel observe detection easily, the concrete plate quality of pouring is good.
As preferably, said substrate is a steel plate, and it is square or circular to be rectangle.
As preferably, said survey rod is a round steel, and quantity is 3 or 4; Survey the edge that rod is evenly distributed on base lower surface, survey the edge that rod is located at substrate, make substrate water smash place in the scope of operation firm; Measure precisely, satisfy the requirement of thick measurement of cast-in-situ floor operation concrete and control.
As preferably, said survey rod and substrate welding.
As preferably, said handrail semicircular in shape, arc or rectangle.
As preferably, said handrail is a round steel, is located at the central authorities of substrate and welds with substrate.
As preferably, said handrail surface is provided with one deck fluorescent paint, makes things convenient for the field operation personnel under darker light or use night.
Whether the beneficial effect of the utility model: it is thick up to standard to detect concrete through the survey rod with the thick grade of concrete height if being; And when placing of concrete, directly be placed on the control survey device on the lower bolster; The real estate of control survey device can be used as the thickness datum of In-situ cast concrete board, uses intuitively eye-catchingly, and convenient measurement is quick; Smear fluorescent paint on the handrail surface, operation is smash in watering when adaptation night or light are not good.
