Background technology
In the work progress of industry and civilian industry, being controlled in work progress of concrete ground surface evenness is a difficult point always.
For many years, construction industry is when carrying out levelling absolute altitude, mostly adopt building leveling layer is set, pre-plugged reinforcement bar in required pour of building exactly, at top, reinforcement bar upper end, smear red paint, the position height of establishing with red paint mark is determined the concrete height of building, build after initial set, then the reinforcing bar and the red paint that expose outside concrete block are polished.But adopt the construction method of this levelling absolute altitude, have following problem: first, because building levelling needs a large amount of reinforcement bars of pre-plugged, easily produce error in setting up procedure, concrete surface planeness can not get effective control all the time thus; Secondly, the use of a large amount of reinforcement bars has not only increased construction cost, and after building, be deposited in reinforcement bar in concrete floor long-time after, due to get rusty etc. problem, can impact terrace itself.
Development along with technology, novel terrace planeness control technology also emerges in an endless stream, these novel technology are not only more accurate to the control of terrace planeness, also saved to a certain extent construction costs, and recoverable high accuracy terrace absolute altitude adjustment structure is exactly wherein a kind of.The method by place in Practical Project according to the block of dividing, longitudinally elevation control line usually adopts the elongated setting of channel-section steel, channel-section steel top absolute altitude is terrace absolute altitude, and the even perforate of channel-section steel waist regulates screw mandrel bottom that fixedly reinforcing bar is set, be embedded in advance in concrete foundation, regulate screw mandrel top to run through the hole of channel-section steel waist, channel-section steel waist bottom arranges regulating nut, pad, and channel-section steel waist top arranges pad, hold-doun nut, by rotation regulating nut, reach the object that changes absolute altitude.Channel-section steel in the method, hold-doun nut, regulating nut and pad are usually reusable, have greatly saved construction costs.Yet absolute altitude regulates screw mandrel to be embedded in advance in concrete foundation, often can only disposablely use, and the high screw mandrel layout points position that regulates of Practical Project acceptance of the bid is more, still has the space that can save; Regulating nut is arranged on channel-section steel bottom, regulates comparatively difficulty, is prone to the phenomenon of channel-section steel off normal in adjustment process.
In sum, for solving the problem of channel-section steel off normal, realize the recoverable that absolute altitude regulates screw mandrel simultaneously, need at present the recoverable high accuracy terrace absolute altitude adjustment structure that a kind of absolute altitude of invention is easy to adjust, precision is high, cost is saved badly, can be used as concrete floor levelling, elevation control use.
Summary of the invention
The purpose of this utility model is take that channel-section steel top is as terrace absolute altitude, take regulating nut and spring as elevation adjusting device, take fixedly reinforcing bar and locating ring is positioner, invent a kind of highly easy to adjust, precision high that has, the terrace absolute altitude adjustment structure of recoverable, can be used as cast-in-place concrete ground surface planeness and absolute altitude and controls construction use simultaneously.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A recoverable high accuracy terrace absolute altitude adjustment structure, is characterized in that, described structure mainly comprises that absolute altitude regulates screw mandrel, channel-section steel, regulating nut and locating ring; The hole that absolute altitude regulates screw mandrel uniformly-spaced to arrange through channel-section steel waist, on screw mandrel on channel-section steel, be provided with regulating nut and nut pad, on screw mandrel under channel-section steel, be disposed with spring Upper gasket, spring, spring lower gasket, hold-doun nut and locating ring, screw mandrel bottom is provided with screw thread, can screw in the absolute altitude being embedded in advance in concrete foundation and regulate in screw mandrel sleeve pipe; The level that is welded with on retainer ring is to fixedly reinforcing bar, the fixedly other end of reinforcing bar and embedded bar welding of crosswise.
Further, the hole aperture ratio absolute altitude of described channel-section steel waist regulates the large 2 ~ 3mm of screw mandrel diameter.
Described absolute altitude regulates in screw mandrel sleeve pipe and is provided with mantle fiber.
Described spring housing regulates screw mandrel outside at absolute altitude, and the upper and lower pad of spring and spring is welded to connect.
The utlity model has following feature and beneficial effect:
(1) absolute altitude being embedded in advance in basis that absolute altitude of the present utility model regulates screw mandrel to screw in mantle fiber regulates in screw mandrel sleeve pipe, after band terrace has been built, only needs reverse rotation absolute altitude to regulate screw mandrel, and just recoverable absolute altitude regulates screw mandrel, saving construction cost.
(2) regulating nut is arranged on channel-section steel waist, and hold-doun nut is arranged under channel-section steel, coordinates spring to carry out adjusting elevation, operates more simple and convenient.
(3) fixedly reinforcing bar is horizontally disposed with, and end is welded with locating ring, and absolute altitude regulates screw mandrel to be difficult for producing off normal, and the horizontally disposed fixedly reinforcing bar later stage can be played and be strengthened interconnective effect.
