AI Technical Summary
In the light steel industry, a 50mm gap is usually reserved between the sole plate of the steel column and the top surface of the concrete foundation, and secondary grouting is required. During the construction period, steel plates need to be temporarily padded to cope with wind loads, resulting in a large amount of steel used and it is difficult to accurately match the gap height.
An adjustable height pad is designed, including upper support, lower support and height adjustment mechanism. Through the screwing depth adjustment of bolts and nuts, the height adjustment of the pad is realized, adapted to different gap heights, and if necessary, steel plates are placed on the surface of the pad to match the gap height.
It effectively saves the amount of steel used, saves about half of the material, and at the same time improves the adjustment ability, can tightly hold the column foot sole plate, avoid gaps, and improves the economic and efficiency of construction.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a height-adjustable pad and a column and foundation supporting structure in a construction stage. Background Art
[0002] In the light steel industry, a 50mm gap is usually reserved between the bottom plate of the steel column foot and the top surface of the concrete foundation. After the column elevation is adjusted, secondary grouting is carried out. During construction, considering the wind load during construction, it is necessary to temporarily place steel plates at the column foot. Usually the steel plate specifications are 40*80mm; the height varies from 30 to 100mm. According to engineering experience, the usual average is about 60mm; a stack weighs 1.5 kg; 4 plates are placed on a column foot, which is 5.6 kg, which is also a lot of material; the worst thing is that since the thickness of the stacked plates may not be able to match the bottom gap exactly, they are often not tight. Utility Model Content
[0003] The utility model aims to provide an adjustable height pad which can fully save the steel consumption of the pad steel plate and is height-adjustable to provide effective leveling support between the column bottom and the foundation, as well as a column and foundation support structure during the construction stage.
[0004] In order to achieve the above-mentioned purpose, the utility model proposes an adjustable height pad, which includes an upper support, a lower support and a height adjustment mechanism;
[0005] The height adjustment mechanism is disposed between the upper support and the lower support, and the distance between the upper support and the lower support is adjusted by the height adjustment mechanism.
[0006] Furthermore, the upper support and the lower support are both a support steel plate.
[0007] Furthermore, the height adjustment mechanism includes a bolt and a nut, the bolt is welded to the upper support, and the nut is welded to the lower support, and the distance between the upper support and the lower support is adjusted by adjusting the screwing depth of the bolt relative to the nut.
[0008] Furthermore, the cross section of the height-adjustable pad is in the shape of a uniform spiral line, and has a good force-bearing structure.
[0009] The utility model also provides a column and foundation support structure in the construction stage, including a steel column, a foundation and a plurality of height-adjustable pads;
[0010] A certain gap is reserved between the base plate of the steel column and the top surface of the foundation, and a plurality of adjustable height pads are arranged in the gap. The support between the steel column and the foundation is achieved by adjusting the height of the adjustable height pads.
[0011] Furthermore, the number of the adjustable height pads is 4, and the 4 adjustable height pads are evenly distributed in the gap.
[0012] Furthermore, the adjustable height of the height-adjustable pad is 40-75 mm.
[0013] Furthermore, if the maximum supporting height of the adjustable height pad is smaller than the height of the gap, a steel plate is placed on the upper surface or the lower surface of the adjustable height pad to match the height of the gap.
[0014] Compared with the prior art, the advantages of the present invention are:
[0015] 1. The gap between the column and the foundation. Compared with the traditional steel plate stacking, the pad of the utility model can save half of the steel consumption due to the height adjustment mechanism, thereby improving the overall economy.
[0016] 2. The height-adjustable pad of the utility model can have better adjustment ability, tightly press against the bottom plate of the column foot, and prevent the generation of gaps. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 2 Schematic diagram of the disassembly of the adjustable height pad in the embodiment of the present invention. DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be further described below.
[0020] like Figure 1 As shown, the utility model proposes a column and foundation support structure in the construction stage, including a steel column 1, a foundation 2 and a plurality of adjustable height pads 3; a certain gap is reserved between the column foot bottom plate of the steel column 1 and the top surface of the foundation 2, and four adjustable height pads 3 are evenly distributed in the gap, and the support between the steel column 1 and the foundation 2 is achieved by adjusting the height of the adjustable height pads 3.
[0021] In this embodiment, the pad includes an upper support 31, a lower support 32 and a height adjustment mechanism; the upper support 31 and the lower support 32 are both a support steel plate; the height adjustment mechanism is a bolt 33 and a nut 34, the bolt 33 is welded to the upper support 31, and the nut 34 is welded to the lower support 32. By adjusting the screwing depth of the bolt 33 relative to the nut 34, the distance between the upper support 31 and the lower support 32 is adjusted to achieve the adjustment of the pad height.
[0022] In this embodiment, the cross-section of the adjustable height pad 3 is a uniform spiral shape and has a good force-bearing structure. In order to further ensure the force-bearing performance of the bolt 33 and nut 34 in the adjustable height pad 3, the adjustment height of the adjustable height pad 3 is set to 40-75mm. If the maximum support height of the adjustable height pad 3 is less than the height of the gap, a steel plate is placed on the upper or lower surface of the adjustable height pad 3 to match the gap height. The adjustable height pad 3 of the utility model not only saves materials, but also has better adjustment capabilities. It can tightly support the bottom plate of the column foot to a height of 60mm and weighs only 0.8 kg. Compared with a stack of steel plates, it saves half of the material.
[0023] The above are only preferred embodiments of the present invention and do not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, may make any equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which shall be deemed as the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
