In the construction process, the height is estimated and adjusted only by the elevation deviation identifier, the scale foundation is avoided, repeated adjustment is needed for many times, and multiple persons are matched to complete the adjustment. Therefore, the construction difficulty is increased, the installation quality is difficult to guarantee, and a large amount of labor is consumed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: for reducing the board top built-in fitting installation degree of difficulty, improve the embedded fitting installation progress, practice thrift the labour. Therefore, the utility model provides a board top built-in fitting elevation fine tuning device.
The utility model provides a board top built-in fitting elevation fine tuning device, specifically is: the screw rod is provided with an adjusting nut matched with the screw rod, the top end of the screw rod is welded with the top seat, the screw rod is arranged in the guide pipe, and the guide pipe is in threaded connection with the base. The guide pipe is provided with a guide bayonet along the axial direction, the side surface of the bottom end of the screw rod is welded with an axial control valve and limited by the axial control valve, and the screw rod can only axially move and cannot rotate in the guide pipe.
Furthermore, the guide pipe is provided with a graduated scale along the guide bayonet, and the telescopic length of the screw rod can be measured according to the graduated scale.
Further, the minimum scale of the graduated scale is 1 mm.
Furthermore, the adjusting nut is a butterfly nut, and operation is convenient.
Furthermore, screw rods with different lengths are arranged to adapt to different plate thicknesses and embedded part elevations, and time required by adjustment of the embedded part elevations is shortened.
The utility model has the advantages of:
the elevation fine adjustment device of the utility model is simple to manufacture, and can be assembled only by cutting according to the size; the material is convenient to obtain, the waste electro-galvanized pipe can be used for manufacturing, and the waste can be recycled; can be repeatedly used in a turnover way, and the length of the screw rod can be changed according to the plate thickness and the embedded part elevation, so that the applicability of the device is improved. The elevation fine adjustment device of the utility model controls the elevation precision of the embedded part through the adjusting nut and the graduated scale, thereby effectively solving the problem of the installation precision of the embedded part on the top of the plate; meanwhile, the adjustment and fixing process can be completed by only one person without retesting, and the adjustment process has reliable basis, so that the rework frequency is greatly reduced, and the labor force is saved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a board top built-in fitting elevation fine tuning device is shown in figure 1, specifically is: the screw rod 2 is provided with an adjusting nut 3 matched with the screw rod, the top end of the screw rod 2 is welded with the top seat 1, the screw rod 2 is arranged in the guide pipe 4, and the guide pipe 4 is in threaded connection with the base 5. The guide tube 4 is provided with a guide bayonet along the axial direction, the side surface of the bottom end of the screw rod 2 is welded with an axial control valve 6 and limited by the axial control valve 6, and the screw rod 2 can only move axially in the guide tube 4 and can not rotate.
Furthermore, the guide tube 4 is provided with a graduated scale 7 along the guide bayonet, and the telescopic length of the screw rod 2 can be measured according to the graduated scale 7.
Further, the scale 7 has a minimum scale of 1 mm.
Furthermore, the adjusting nut 3 is a butterfly nut, so that the operation is convenient.
Furthermore, the screw rods 2 with different lengths are arranged to adapt to different plate thicknesses and embedded part elevations, and the time required by the adjustment of the embedded part elevations is shortened.
The method comprises the following steps:
1) and (5) repeatedly measuring all the roughly-installed embedded part elevations by using the level gauge and marking elevation deviation values.
2) And placing the elevation fine adjustment device at the bottom of the embedded part at the top of the plate with elevation deviation.
3) The height of the adjusting screw rod 2 is adjusted by screwing the adjusting nut 3, and then the elevation is controlled by observing the graduated scale 7 (the positive and negative deviations can be adjusted).
4) And after the embedded part is adjusted, welding and fixing (checking a small amount of retest, and checking the adjustment precision).
5) And adjusting the adjusting nut 3 back, taking out the elevation fine adjustment device, and adjusting the next embedded part.
The embodiment and the effect are as follows:
the work load is to showing for example table 1 around the fine tuning device of elevation of a certain building site is using the utility model discloses a.
TABLE 1 USE the utility model discloses a comparison of engineering volume around elevation fine tuning device
According to the market price at that time: and calculating by 300 yuan per work day. Use the utility model discloses a before the elevation fine tuning device, the recruitment expense is: (37+51) × 300 ═ 26400 yuan. Use the utility model discloses an after the elevation fine tuning device, elevation fine tuning device expense is: (6+9) × 30 ═ 450 yuan; the labor cost is as follows: (23+32) × 300 ═ 16500 members. The cost is saved: 26400 and 450 and 16500 to 9450.
Through comparison, the cost is saved after the plate top embedded part installing device is used, and the problem of installation accuracy of the plate top embedded part is effectively solved.
