That is, as the lifting height of the lifting device is adjusted, the pin shaft can ascend or descend along the long hole, so that the elevation of the upright post 10 meets the design requirement. In this embodiment, when the stand is at the set elevation, the pin shaft has a distance of the set threshold from both the top side and the bottom side of the long hole. That is, when the pin is at a predetermined elevation, the pin is located between the top and bottom sides of the slot. And the distance between the top side and the pin shaft and the distance between the bottom side and the pin shaft can be used as the threshold value of the height adjusting range of the upright column. Namely, the distance between the pin shaft and the top side forms a threshold value for vertically and upwardly adjusting the upright column; the distance between the pin shaft and the bottom side forms a threshold value for vertically and downwardly adjusting the upright column.

The hollow area may be used to place jacking devices and the reference line of the backing plate 122 may be exposed to facilitate alignment of the backing plate 122 with the column 10. In a preferred embodiment, the outer profile of the backing plate 122 is rectangular. Since the rectangle has perpendicular long and wide sides, the long and wide sides of the pad plate 122 can be easily aligned with the reference line of the pad plate 122.

As shown in fig. 1, in an embodiment of the present invention, the bracket 12 further includes a plurality of supporting members 124 disposed along the vertical direction, and the supporting members 124 are uniformly distributed. In a preferred embodiment, the contour of the backing plate 122 is rectangular, and four supports 124 are welded to four corners of the backing plate 122, respectively. In this embodiment, the supporting member 124 is made of channel steel, which has high strength and is not easy to deform, so as to support the upright post 10 well.

As shown in fig. 1, in an embodiment of the present invention, two adjacent supporting members 124 are connected by a diagonal brace 126. The diagonal brace 126 may be made of steel bars, round tubes, or the like. Brace 126 may stiffen bracket 12 such that bracket 12 may be a more stable system.

As shown in fig. 1, in an embodiment of the present invention, a lifting lug for connecting a lifting device is provided on the upright post 10. In a preferred embodiment, the distance between the lifting lug and the top end of the upright 10 is one third of the length of the upright 10. The lifting lug greatly facilitates the lifting operation and elevation adjustment of the upright post 10.

In an embodiment of the present invention, the jacking device may be a jack.

The assembling process of the pillar mounting structure will be described with reference to fig. 2 to 8 of the drawings attached to the specification.

In an embodiment of the present invention, the floor slab cushion construction is performed first. In the link, foundation backfill construction is carried out; and after the construction is finished, the ramming coefficient of the plain soil needs to reach 0.95. And after the tamping operation is finished, pouring concrete on the tamped soil layer to build the floor slab cushion layer.

In an embodiment of the present invention, after the construction of the floor mat layer is completed and the expected strength is reached, the measurement setting line can be performed, and then the installation reference line of the backing plate 122 is set.

As shown in fig. 2, in an embodiment of the present invention, after the reference line of the backing plate 122 is drawn, the position of the backing plate 122 is determined according to the reference line. Backing plate 122 is then secured to the floor mat, such as by cement nails or anchors. In this embodiment, the backing plate 122 has a positioning function to help determine the installation position of the upright 10 and the bracket 12.

In this embodiment, the backing plate 122 may be an annular plate. Specifically, the outermost contour of the pad 122 is rectangular, and the contour of the hollow portion of the pad 122 is also rectangular. After the backing plate 122 is fixed on the cushion layer by the cement nails, the reference line of the backing plate 122 can be observed in the hollow area of the center of the backing plate 122, so that the installation error of the backing plate 122 can be reduced. Of course, in some other embodiments, the backing plate 122 may be a complete plate, and may be formed in any shape, such as a circle, a trapezoid, a parallelogram triangle, etc.

In one embodiment of the present invention, after the backing plate 122 is fixed, the vertical column 10 is hoisted. Specifically, the operation is divided into two steps.

As shown in fig. 3, in a first step the mast 10 is hoisted and moved by means of a hoisting device to a position above the support structure (not shown) and from this position the mast 10 is slowly lowered until the mast 10 reaches a desired position. In this ideal position, the shaft of the upright 10 is inclined 10-30 degrees (e.g. 20 degrees) to the direction of the vertical floor slab underlayment, the bottom end 102 of the upright 10 is suspended, and the beam of the support structure is above the top end of the upright 10. In some preferred embodiments, the upright post 10 is provided with a lifting lug, and the distance between the lifting lug and the top end of the upright post 10 is one third of the length of the upright post 10. The lifting lugs in this position help maintain the mast 10 at a preferred angle of inclination during lifting to facilitate control and installation of the mast 10 by the builder. It should be noted that the support structure provided with the beams may be constructed either before or during the hoisting operation. In this embodiment, the support structure may be a large steel structure building.

And secondly, connecting the top end of the upright post 10 with a connecting plate of a beam through the matching of a hoisting device and manual operation. In the process, the pin holes at the top end of the upright 10 and the long holes of the connecting plate (of the beam) are aligned to enable the upright 10 and the beam to be in a connecting and positioning state. The pin spacers are then inserted into the gap between the top end of the upright 10 and the connecting plate. In some embodiments, because the gap is narrow, a short rod of steel reinforcement may be welded to the pin washer, and then the pin washer may be slowly fed into the gap by manipulating the short rod of steel reinforcement and aligning the hole of the pin washer with the long hole and the pin hole. Then, the pin shaft is inserted through the long hole, the pin hole and the hole of the pin shaft gasket, and the pin connection of the upright column 10 and the beam is completed. In some other embodiments, the upright 10 may be pivotally connected to the beam by other means, such as by a living rivet. It is within the contemplation of the invention that the control post 10 can be in a vertical (or perpendicular to the floor mat) position.

As shown in fig. 3, in an embodiment of the present invention, after the column 10 is connected to the beam, the height-adjustable jacking device is disposed at the center of the steel pad plate 122, and then the height of the jacking device is increased.

In this embodiment, the column 10 is still suspended by the lifting device, and the column 10 is controlled not to move, so as to prevent the pin from being damaged by the force applied by the column 10.

As shown in fig. 4, in an embodiment of the present invention, after the height adjustment of the jacking device is completed, the upright 10 is slowly lowered until the upright 10 is in a vertical state (i.e. the shaft of the upright 10 is perpendicular to the floor mat). At this point, the jacking device is still directly below the center of the bottom end 102 of the mast 10. In this embodiment, the column 10 is still in a suspended state to avoid the pin from being damaged by the force applied by the column 10. It should be noted that, when the upright post 10 is in the vertical state, the distance between the top of the jacking device and the bottom end 102 of the upright post 10 should be 3 cm-8 cm, which is helpful to reserve a space for adjusting the verticality of the upright post 10.

In an embodiment of the present invention, after the stand column 10 is completely lowered, the height of the jacking device is adjusted until the top of the jacking device contacts the bottom end 102 of the stand column 10. Then, through the cooperation of sopwith staff and prism, continue to adjust jacking device's height to realize the more accurate adjustment to the elevation and the coordinate of stand 10, so that each item parameter of stand 10 accords with the design requirement. In this embodiment, the column 10 with the adjusted elevation and coordinates is supported by the jacking device, and then the hoisting device is cancelled to hoist the column 10. That is, the column 10 is supported entirely or mainly by the jacking devices to maintain the upright state.

As shown in fig. 5, in an embodiment of the present invention, after the elevation and coordinates of the column 10 are adjusted, a plurality of support members 124, which are previously blanked, are vertically disposed between the backing plate 122 and the bottom end 102 of the column 10, and the bottom ends of the support members 124 are fixedly connected (e.g., welded) to the backing plate 122. When all the supporting members 124 are connected to the backing plate 122, all the supporting members 124 and the backing plate 122 together constitute the bracket 12. As shown in fig. 6, two adjacent supporting members 124 may be reinforced by a diagonal brace 126, so that the bracket 12 forms a more solid whole. Of course, after all the supports 124 have been connected to the backing plate 122, the elevation of the column 10 is retested. If the deviation is found, the elevation of the upright post 10 is adjusted in time by changing the height of the jacking device until the elevation of the upright post 10 meets the design requirement.

It should be noted that, since the supporting members 124 are made by pre-blanking, and the size thereof meets the design requirements, even if there is a deviation in the elevation of the vertical column 10, the actual deviation is not particularly large (for example, the deviation of the elevation is allowed to be within 5mm during the construction process, and the actual deviation is 5mm to 7mm), so that the deviation can be remedied by the constructor only by adjusting the height of the jacking device. In other words, the elevation adjustment by the jacking device after the bracket 12 is made is due to the fact that the actual deviation is within the range that can be remedied, otherwise the column mounting structure 10 is unusable. This is, of course, common knowledge to the skilled person.

In one embodiment of the present invention, all of the support members 124 can be welded to the bottom end 102 of the column 10 after the elevation of the column 10 meets the design requirements. The height of the jacking device can be adjusted downwards, and the jacking device can be taken out. Of course, it is also possible to lower the height of the jacking device and to remove the jacking device, which can continue to support the upright 10 together with the carriage 12.

In one embodiment of the utility model, after the jacking device is taken out, the binding operation of the floor slab reinforcement cage is carried out; or after all the supporting pieces 124 are welded with the bottom ends 102 of the upright columns 10, the floor slab reinforcement cage binding operation is carried out. In this embodiment, the floor reinforcement cage is disposed around the bracket 12, and the height of the floor reinforcement cage is less than or equal to the height of the bottom end 102 of the column 10.

The utility model discloses an in the embodiment, after terrace plate steel reinforcement cage ligature was accomplished and was approved, concrete begins to pour. In this embodiment, the upright post 10 is in a vertical state (i.e. the shaft of the upright post 10 is perpendicular to the floor mat layer at this time), the bottom end 102 of the upright post 10 has a bottom plate parallel to the floor mat layer, and the bottom plate is provided with bolt holes penetrating through the bottom plate. Before concrete is poured, the positions of the bolt holes need to be sealed by adhesive tapes so as to avoid the pollution of the concrete to the bolt holes. When pouring the concrete, the concrete is poured under the floor, and the bracket 12 is completely submerged by the concrete. After the concrete reaches a predetermined strength, the floor is positioned above and in contact with the concrete.

As shown in fig. 7, in an embodiment of the present invention, after the concrete for placing the floor slab satisfies a predetermined strength, the drilling operation is performed along the bolt hole of the bottom plate. After the drilling operation is completed, chemical anchors are implanted into the bolt holes and the holes in the concrete. The columns 10 are firmly fixed to the concrete by installing chemical anchors.

In connection with the above-described construction process, the brackets 12 are used to support and connect the columns 10. On one hand, the bracket 12 is manufactured in the process of installing the upright post 10, so that the construction time is shortened; on the other hand, the bracket 12 and the floor slab reinforcement cage can be poured together by the concrete, so that the upright post 10 is prevented from being installed by digging an opening on the concrete, and the construction time is shortened.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
