Abstract

The utility model relates to the field of electronic factory building construction, in particular to a height-adjustable raft plate flatness control track; the method is characterized in that: including foundation column, crossbeam, sleeve pipe and locking bolt, wherein, the both ends of crossbeam set up the sleeve pipe, and the foundation column has two, the crossbeam is established on two foundation columns through the sleeve pipe of establishing at its both ends and the cover, and open at the sheathed tube lateral wall has the screw, penetrates locking bolt in the screw, through screwing up locking bolt and with sleeve pipe and foundation column fastening connection. This control track adopts above-mentioned structural design, and it adjusts the elasticity between sleeve pipe and the foundation through the locking bolt when using to reach the adjustable purpose of crossbeam and the regulation of the raft board roughness of finally being convenient for.

Description

Height-adjustable raft plate flatness control track

Technical Field

The utility model relates to a building field of electron factory building specifically is a but height-adjusting's raft board roughness control track.

Background

The raft foundation can not only give full play to the bearing capacity of the foundation and adjust the uneven settlement, but also meet the space use requirement, thereby becoming a more ideal foundation form. However, because the raft is large in area and poor in flatness control, the electronic factory building has high requirements for ground flatness, elevation needs to be repeatedly measured for many times before the raft is poured, the flatness of the raft is guaranteed, the existing common site construction method is to weld steel bars, and the elevation is modified in repeated measurement for many times. Such operation process is very extravagant time and the whippletree is difficult to keep at same level among the welding process, and elevation measuring effect can't guarantee promptly.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned defect, provide a control track for raft board roughness is adjusted.

In order to achieve the above object, the present invention is realized as follows:

a height-adjustable raft plate flatness control track; including foundation column, crossbeam, sleeve pipe and locking bolt, wherein, the both ends of crossbeam set up the sleeve pipe, and the foundation column has two, the crossbeam is established on two foundation columns through the sleeve pipe of establishing at its both ends and the cover, and open at the sheathed tube lateral wall has the screw, penetrates locking bolt in the screw, through screwing up locking bolt and with sleeve pipe and foundation column fastening connection.

The height-adjustable raft plate flatness control track; the foundation columns are arranged on the base surface of the building floor slab.

This control track adopts above-mentioned structural design, and it adjusts the elasticity between sleeve pipe and the foundation through the locking bolt when using to reach the adjustable purpose of crossbeam and the regulation of the raft board roughness of finally being convenient for.

Drawings

Fig. 1 is a schematic structural diagram of the control track.

Detailed Description

The invention is further illustrated by the following specific examples.

As shown in fig. 1, a height adjustable raft plate flatness control track; including foundation column 1, crossbeam 2, sleeve pipe 3 and locking bolt 4, wherein, the both ends of crossbeam 2 set up sleeve pipe 3, and foundation column 1 has two, crossbeam 2 overlaps through the sleeve pipe 3 of establishing at its both ends and establishes on two foundation columns 1, and the screw has been opened to sleeve pipe 3's lateral wall, penetrates locking bolt 4 in the screw, through screwing up locking bolt 4 and with sleeve pipe 3 and foundation column 1 fastening connection.

The height-adjustable raft plate flatness control track; the foundation column 1 is arranged on the base surface of the building floor.

The control track adopts the structural design, and the specific application method is as follows:

step 1, when a large-area raft is poured, firstly, the raft is divided into long strips, then 2 vertical reinforcing steel bars with the distance of 20cm are welded on top reinforcing steel bars at intervals of 2m, then elevation points are marked on the vertical bars, cross bars are sleeved on the vertical bars, and screws are screwed at the corresponding elevation positions for fixing; in the subsequent retest process, if the elevation is not right, the horizontal pole is adjusted from top to bottom through unscrewing the screw until the correct elevation is fastened again.

And 2, the width of the divided area is not too wide, otherwise, manual leveling is not convenient, and the fine leveling effect cannot be achieved.

And 3, pouring a small amount of concrete at the position of the cross rod during plastering, and filling after the section of the cross rod and the track are plastered and removed.

Claims

1. The utility model provides a but height-adjusting's raft board roughness control track, characterized by: including foundation column, crossbeam, sleeve pipe and locking bolt, wherein, the both ends of crossbeam set up the sleeve pipe, and the foundation column has two, the crossbeam is established on two foundation columns through the sleeve pipe of establishing at its both ends and the cover, and open at the sheathed tube lateral wall has the screw, penetrates locking bolt in the screw, through screwing up locking bolt and with sleeve pipe and foundation column fastening connection.

2. The adjustable height raft plate flatness control track of claim 1, further comprising: the foundation columns are arranged on the base surface of the building floor slab.
