Example 1

As shown in fig. 1-3, a bottom plate fixing structure for module installation includes a steel plate 3 and a module base 10, the steel plate 3 is fixed on the upper surface of a concrete foundation 1 through four anchor bolts 4, the steel plate 3 is separated from the concrete foundation 1 through a cushion block 2, a secondary concrete layer 6 is filled in a gap, the aperture of a through groove formed in the surface of the steel plate 3 and used for accommodating the anchor bolts 4 is larger than the diameter of the anchor bolts 4 and is fixed through a gasket 5, an elongated slot 7 used for accommodating an elongated bolt 8 is formed in the upper surface of the steel plate 3, and the diameter of the elongated bolt 8 is smaller than the width of the elongated slot 7;

the bottom end surface of the module base 10 is fixedly connected with a bottom plate 11, wherein a through hole 12 for butting with the long-foot screw 8 is formed in the surface of the bottom plate 11, and a fixing bolt 13 for fixing the bottom plate 11 is arranged.

The anchor bolt 4 is fixed on concrete foundation 1 through 4 preformed holes to steel sheet 3, the size is 50 millimeters less than each limit of 1 size of concrete foundation, concrete foundation 1 has been reduced to the high accuracy requirement of anchor bolt 4 coordinate, the basic construction technology has been simplified, wherein anchor bolt 4's effect is tentatively fixed to steel sheet 3, therefore, the fastness requirement to its fixing is not high, logical groove aperture that steel sheet 3 surface was seted up is greater than anchor bolt 4, then fix through gasket 5, it is not high to lead to the big precision requirement when anchor bolt 4 is pre-buried of groove aperture, convenient construction, a long foot screw 8 that is used for fixed module base 10 calibrates the position earlier, long foot screw 8 acts as pre-buried bolt and fixes bottom plate 11 after secondary concrete layer 6 solidifies, and long foot screw 8's pre-buried in-process, low to the requirement of construction precision, can not cause the unable butt joint phenomenon of bolt and through-hole 12.

In the specific construction process, the elevation of the steel plate 3 can be adjusted before being installed through the cushion block 2, the elevation error can be controlled to be between minus 5mm and 0mm, the quality controllability is improved, the adjustable amount of at least 75mm is increased in the extending direction of the long groove 7 of the module base 10, an adjusting space is also formed in the vertical direction, the centers of the anchor bolt holes and the module base 10 do not need to be accurately measured according to a traditional construction method, the center prefabrication and transportation deformation errors of the module base 10 do not need to be excessively worried about, redundant processes caused by center mismatching of chambering and the like when the module base 10 is in place are avoided, and the module base 10 can be placed in place at one time conveniently.

The upper surface of the steel plate 3 is further provided with a vibrating hole 9, after the module base 10 is in place, the fixing bolt 13 is screwed, the long-foot screw 8 is automatically calibrated in the process, the bottom end of the long-foot screw 8 and the secondary concrete layer 6 move, and the part is filled through vibrating, so that the strength is improved.

The bottom opening of the through hole 12 is funnel-shaped, which is convenient to butt joint with the long-foot screw 8.

The bottom end of the long-foot screw 8 is arranged in contact with the upper surface of the concrete foundation 1, so that the long-foot screw 8 is buried in the secondary concrete layer 6 to the maximum extent.

The implementation mode specifically comprises the following steps: at first when concreting concrete foundation 1, pre-buried rag bolt 4, then set up cushion 2 and steel sheet 3 on

concrete foundation

1, 3 four corners departments of steel sheet have seted up logical groove and the butt joint of rag bolt 4, wherein the aperture ratio of logical groove is 4 big than rag bolt, the installation degree of difficulty has been reduced, it is lower to the pre-buried required precision of rag bolt 4 simultaneously, rag bolt 4 passes through 5 fixes steel sheet 3 on cushion 2 surfaces with gasket, wherein rag bolt 4 only plays preliminary fixed steel sheet 3's effect, consequently, it is big than rag bolt 4 to lead to the groove can design into, easy to assemble steel sheet 3.

Pouring a secondary concrete layer 6 from the long groove 7 to enable the gap between the steel plate 3 and the concrete foundation 1 to be filled with concrete slurry, then inserting a long-foot screw 8 into the long groove 7, enabling the long-foot screw 8 to penetrate into the uncured secondary concrete layer 6, finally enabling the module base 10 to enter the field, enabling the long-foot screw 8 to enter the through hole 12, enabling the long-foot screw 8 to properly change the position and align to the through hole 12, calibrating the position of the long-foot screw 8 by screwing a fixing bolt 13, enabling the bottom end of the long-foot screw 8 to transversely move in the secondary concrete layer 6 while in the calibrating position, leaking a gap, then extending a vibrator into the vibrating hole 9 to vibrate to enable the concrete around the long-foot screw 8 to be filled, and after the secondary concrete layer 6 is completely cured, forming a new embedded bolt by the long-foot screw 8, wherein the fixing strength of the embedded bolt is the same as that of the foundation bolt 4, but the requirement on the construction positioning accuracy is greatly reduced, the fault tolerance rate is high, and the phenomenon that the alignment is difficult can not occur.
