Description

The leveling unit of usefulness is built on the plane

Technical field

The utility model discloses a kind of plane and build the leveling unit of usefulness, is a kind of construction equipment of levelling and lattice when being used for whole building ground and building, and can improve the integral level degree of building on ground.

Background technology

In the work progress of industry and civilian construction, the cast-in-situ concrete terrace must be to required concrete leveling absolute altitude of building before building.

Building operations industry in the past is when carrying out the levelling absolute altitude, often adopt and bury reinforcement bar in advance underground, red paint is smeared at top, upper end at reinforcement bar, determine the concrete height of building with the position height that the red paint mark is established, after building initial set, prescind will exposing the reinforcing bar of building outside the top layer, polish with red paint.Adopt the method for this levelling absolute altitude, exist very big problem: first, owing to will bury a large amount of reinforcing bars in advance underground, on every reinforcing bar, make marks, error can appear unavoidably, it is big more to build area, exists the possibility of error just big more, and the planeness of concrete surface can not get effective control all the time so; The second, use a large amount of reinforcing bars not only to increase construction cost, and just be deposited in after building in the terrace, long-time after because the problem such as get rusty of reinforcement bar also can impact building itself.

In recent years, when building operations levelling absolute altitude, also adopt in such a way.Being exactly first joints cement mortar rail bar, the square crossing of rail bar is overlapped to form frame, is the terrace absolute altitude with the suitable for reading of every rail bar.Its shortcoming is: the first, and mortar rail bar is made complicated, need reach identical standard, and consume material is made the time that maintenance needs a week again, is damaged easily again in construction, thereby influences the absolute altitude precision; Second, it all must be cut, walks clearly after building, otherwise can be because rail bar and the old and new different with the material of building ground build bonding problem such as bad, and cause day and problems such as crack, back, seepage, and cut the rail bar is thing when quite taking a lot of work, the short slot that also it will have been stayed after having cleared up fills up smooth, is difficult to guarantee the smooth precision of integral terrace after filling up.

The utility model content

The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of simple in structure, leveling unit that usefulness is built on the obvious results plane, and this device helps regulating height, and reusable.

The purpose of this utility model is achieved in that the bracing frame that comprises crossbeam and bottom thereof, it is characterized in that: also include nut, the upper and lower corresponding surface of crossbeam is respectively equipped with on same axial line and the macropore that communicate in the center of circle, aperture, bracing frame comprises screw rod, adjusting nut and keeper, and screw rod is all spiral being connected with adjusting nut, the keeper of the nut that places macropore, crossbeam below.

Described crossbeam is the hollow type rectangular structure, and the screw in the nut equates that with the pore size of aperture the height of nut is not more than crossbeam thickness.Its middle cross beam is the construction needs for the square structure, and is convenient to the fixing of nut; The effect of hollow type structure mainly is to alleviate the measurement overall weight, helps convenient in carrying, and saves cost.Purpose to the qualification of nut height is to be: after nut is fit into macropore, the end face of nut is equal with the last plane of crossbeam, the bottom surface of nut then places on the crossbeam inwall at aperture place, and this moment nut and aperture and macropore central axis all on same straight line.

Support frame as described above quantity serves as preferred with two, evenly is located at position, the crossbeam left and right sides; Correspondingly, the macropore on the crossbeam, aperture, nut all are set to preferably with about two correspondences.This qualification effect is to be supported by left and right sidesing supporting frame, makes crossbeam keep balance.The quantity of bracing frame also can promptly be supported in the intersection of diagonal place of the baseplane of crossbeam for single, and this mode also can reach effect of the present utility model, just operates difficultly, and influenced by external force and influences level.The quantity of bracing frame can also still be considered the construction cost problem for more than two, so bracing frame quantity is got two left and right ends of distribution crossbeam as of the present utility model preferred.

An area minimum lateral of described crossbeam is provided with a core body, and the vestibule on the crossbeam of the corresponding end with it of the size of this core body is suitable.When being used for large-area flooring levelling native system is interconnected.

Described keeper adopts expansion bolt, helps combining firmly with the bottom surface, makes equipment the back is installed steadily.

When the utility model is used in flooring levelling when building, its operating principle is: earlier basic unit's ground line is cleaned out, water seasoning makes ground fully moistening, determines the layout of crossbeam again according to ground shape.Generally arrange continuously, the crossbeam of this device long side direction head and the tail tandem according to ground is connected along the longer sides direction of earth construction; And ground than short side direction on place this device and be advisable with interior spacing with 6 meters, promptly the spacing between two crossbeams arranged side by side is controlled in 6 meters; On ground line, play the lattice line of ink marker then, according to the position correspondence in the hole on the crossbeam at surface drilling, the degree of depth in hole is advisable with about 2.5 centimetres, influence its supporting capacity to prevent to get to the pre-buried reinforcing bar in the floor, then expansion bolt is placed one by one in the hole and the abundant and bloated reality in ground, the screw rod of screwing on then, put on the screw rod with nut that it matches after insert in the aperture of crossbeam, again an end that is provided with internal thread in the nut is inserted by macropore and it is screwed on the screw rod and get final product with sleeve barrel tool, build required absolute altitude by adjusting nut control, and about adjust its levelness, adjust the back is fixed crossbeam by nut screwing clamping smoothness.When build finish after, with instrument nut is back-outed, split out crossbeam, the expansion bolt of again screw rod being back-outed, expansion bolt finally is fixed in the ground concrete, the part of dismounting can be reused.

When this device is applied in basic unit when building, keeper can omit and not use, and directly the bottom of screw rod is fixed, and only dismantles the crossbeam and the nut of this device after building, and screw rod and adjusting nut stay in the concrete structure that solidifies.

Below in conjunction with description of drawings and specific embodiment the utility model is further specified:
