Description

Technical Field

[0001] The utility model relates to the field of steel structure columns, in particular to a bottom giant steel column installation structure based on a steel horse stool base connection. Background Art

[0002] With the increasing application of steel structures in construction projects, steel structures have become an indispensable structural form in modern buildings due to their advantages such as light weight, high strength, small component cross-section, excellent seismic performance, short construction period, and large effective space. As a key component of steel structures, the installation quality of steel column foundations directly affects the stability and safety of the entire building. Therefore, the research and progress of steel column installation technology has important theoretical and practical significance for ensuring the quality of steel structure buildings.

[0003] When installing steel structures, in order to ensure the installation quality of the giant steel columns at the bottom, it is necessary to consider the impact of factors such as foundation conditions, geometric dimensions of steel columns, and connection methods on the installation accuracy and stability of steel columns. Therefore, in order to improve the quality and efficiency of steel column installation, it is necessary to take necessary measures to ensure the installation accuracy of steel columns, especially the first section of steel columns connected to the foundation, whose installation accuracy plays an important role in controlling the overall installation quality of the steel structure. At present, when installing steel columns, the method of welding embedded parts on the foundation steel bars is usually adopted, and the embedded parts including support pallets, multiple support columns and connecting screws are inserted and welded on the foundation steel bars. First, when installing traditional embedded parts, it is necessary to adjust the position of each support column so that it can contact smoothly with the threaded steel bars in the foundation below, so as to facilitate welding of the two. When the arrangement spacing of the steel bars below cannot meet the positioning requirements of the embedded parts, it is necessary to readjust the arrangement of the already tied steel bars, which is time-consuming and laborious. Secondly, when the spacing of the foundation steel bars is dense, it is not conducive to the installation of multiple support columns under the support plate. The narrow operating space will also bring great obstacles to the welding operation, and even affect the welding quality in severe cases. Finally, the positioning and installation of traditional embedded parts are usually carried out in the early stage of steel bar binding. Since steel bar binding operations will be carried out later and concrete has not been poured during this process, the position and level of traditional embedded parts are easily affected by the movement of the steel bar position during the subsequent binding process, resulting in reduced embedding accuracy. Therefore, it is usually necessary to make secondary adjustments to the elevation, horizontal position, levelness, etc. of the embedded parts, which wastes manpower, material resources and construction period, and ultimately affects the progress and cost of the project. Utility Model Content

[0004] The purpose of the utility model is to provide a solution that can improve the installation accuracy of steel columns and save manpower and material resources in view of the shortcomings of the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a bottom giant steel column installation structure based on a steel horse stool base connection, including a foundation cushion layer positioning embedded part and a steel horse stool base, the foundation cushion layer positioning embedded part is pre-arranged in the foundation cushion layer, the steel horse stool base includes a plurality of vertical steel horse stool angle steel columns and a plurality of horizontal steel horse stool horizontal angle steels, the top of the steel horse stool angle steel column is welded and fixed to the corresponding steel horse stool horizontal angle steel, the steel horse stool angle steel columns on each side are connected by welding steel bars, the bottom of the steel horse stool angle steel column is welded and fixed to the corresponding foundation cushion layer positioning embedded part, the steel horse stool base is arranged inside the foundation pedestal, and the steel horse stool base is welded and fixed to the bottom of the steel column.

[0006] Furthermore, the upper surface of the foundation cushion layer positioning embedded parts is set horizontally, and the elevations of different foundation cushion layer positioning embedded parts are set on the same horizontal plane.

[0007] Furthermore, the foundation cushion positioning embedded part is a structure of an upper steel plate and a lower threaded planting rod.

[0008] Furthermore, the steel horse stool angle steel columns adopt the same specification and length so that the support surface elevation of the steel horse stool horizontal angle steel is maintained on the same horizontal plane, and the steel horse stool angle steel columns correspond one-to-one with the foundation cushion positioning embedded parts.

[0009] Furthermore, part of the horizontal steel bars of the foundation pedestal are tied and fixed to the top of the steel horse stool base.

[0010] Furthermore, the side length of the steel horse stool base is smaller than the diameter of the steel column, and the diagonal length of the steel horse stool base is greater than the diameter of the steel column.

[0011] The above solution of the utility model has the following beneficial effects:

[0012] The bottom giant steel column installation structure based on the steel horse stool base connection provided by the utility model aims at the problems that the bottom installation positioning of the giant steel column is difficult and the elevation and level adjustment are difficult. According to the foundation cushion thickness and the steel column geometric lofting result, the foundation cushion layer positioning embedded parts are reserved in the cushion layer, which greatly facilitates the adjustment and determination of the steel column position, elevation and level, ensures the installation accuracy of the steel column, and saves manpower and material resources. At the same time, in view of the problems that the steel bars are densely arranged and the working space is narrow inside the foundation pedestal of the giant steel column, the steel horse stool base is relied on to complete the positioning and installation of the steel column connection base in advance before the steel bars of the foundation pedestal are tied, thereby reducing the welding work in the dense steel bar space below the connection surface, ensuring that the welding work is carried out in a wider operating space, and ensuring the welding quality. In addition, the prefabricated steel horse stool base is directly welded to the foundation cushion layer positioning embedded parts, thereby avoiding the influence of steel bar displacement during the subsequent steel bar tying operation, reducing the secondary adjustment of the base elevation, horizontal position and level before the steel column is installed, ensuring the installation accuracy of the steel column, and saving manpower, material resources and construction period.

[0013] Other beneficial effects of the present invention will be described in detail in the subsequent specific implementation sections. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 As shown, an embodiment of the utility model provides a bottom giant steel column installation structure based on a steel horse stool base connection, including a foundation cushion layer positioning embedded part 1. Among them, the foundation cushion layer positioning embedded part 1 is pre-placed in the foundation cushion layer 2 according to the thickness of the foundation cushion layer 2 and the geometric lofting result of the steel column. The number of foundation cushion layer positioning embedded parts 1 is consistent with the number of columns on the steel horse stool base 3. The embedded part is in the form of an upper steel plate plus a lower threaded planting rod. When pre-placed, the focus is on adjusting and determining the elevation, horizontal position, and horizontality of the embedded part. After placement, measurement and verification are carried out to ensure that the upper surface of the foundation cushion layer positioning embedded part 1 is horizontal and the elevations of different foundation cushion layer positioning embedded parts 1 are on the same horizontal plane.

[0026] The steel horse stool base 3 can be installed only after the concrete of the foundation cushion layer 2 is poured and reaches the specified curing strength. The steel horse stool base 3 is prefabricated in the factory. The steel horse stool base 3 is mainly composed of eight vertical steel horse stool angle steel columns 4 and four horizontal steel horse stool horizontal angle steels 5. The top of the steel horse stool angle steel column 4 is welded and fixed to the steel horse stool horizontal angle steel 5 on the corresponding side. The steel horse stool angle steel columns 4 on each side are connected by welded steel bars 6 to improve the overall rigidity of the steel horse stool base 3. Among them, the steel horse stool angle steel columns 4 use the same specification length to keep the support surface elevation of the steel horse stool horizontal angle steel 5 on the same horizontal plane. After entering the site, the steel horse stool base 3 is installed in alignment with the foundation cushion layer positioning embedded parts 1 to ensure the accurate position of the steel horse stool base 3. Finally, the bottom of the steel horse stool angle steel column 4 is welded and fixed to the corresponding foundation cushion layer positioning embedded parts 1.

[0027] At the same time Figure 2 As shown, the steel horse stool base 3 is arranged inside the foundation pedestal 7. Since the horizontal and vertical steel bars 8 are densely interlaced inside the pedestal foundation 7 of the giant steel column, the horizontal steel bars 8 can be first tied to the vicinity of the top elevation of the steel horse stool base 3, and the foundation pedestal 7 can be poured with the first concrete pouring so that the pouring rough surface is slightly lower than the top elevation of the steel horse stool base 3. When the concrete reaches the specified curing strength, it can not only ensure the rigidity and load-bearing capacity of the steel horse stool base 3, but also reserve sufficient working space for the next step of steel column installation. After the foundation pedestal 7 is poured with concrete for the first time and reaches the specified curing strength, the first section of the bottom of the steel column can be installed. At the same time, Figure 3 As shown, after the prefabricated steel column arrives at the site, the steel column is first hoisted above the steel horse stool base 3, the position of the steel column is measured and adjusted so that the steel column and the steel horse stool base 3 are centered along the vertical axis, and finally the bottom of the steel column is welded and fixed to the steel horse stool horizontal angle steel 5.

[0028] It should be noted that, in this embodiment, the side length of the steel horse stool base 3 should be slightly smaller than the diameter of the steel column connected thereto, and the diagonal length of the steel horse stool base 3 should be slightly larger than the diameter of the steel column. Figure 4 As shown, the steel column and the steel horse stool horizontal angle steel 5 have a larger connection area and a longer welding length.

[0029] After the steel column is accurately installed and verified, the foundation pedestal 7 and the steel bars 8 around the steel column can be tied upwards. After the steel bars 8 are tied, the foundation pedestal 7 can be poured for the second time.

[0030] As described above, the bottom giant steel column installation structure based on the steel horse stool base 3 provided in this embodiment aims at the problem that the bottom installation positioning of the giant steel column is difficult and the elevation and level adjustment are difficult. According to the thickness of the foundation cushion 2 and the geometric lofting result of the steel column, the foundation cushion positioning embedded parts are reserved in the cushion, which greatly facilitates the adjustment and determination of the position, elevation and level of the steel column, ensures the installation accuracy of the steel column, and saves manpower and material resources. At the same time, in order to solve the problems that the steel bars 8 are densely arranged inside the foundation pedestal 7 of the giant steel column and the working space is narrow, the steel horse stool base 3 is used to The positioning and installation of the steel column connection base is completed in advance before the steel bars 8 of the foundation pedestal 7 are tied, which reduces the welding work in the space with dense steel bars 8 below the connection surface, ensures that the welding work is carried out in a wider operating space, and ensures the welding quality; in addition, the prefabricated steel horse stool base 3 is directly welded to the foundation cushion positioning embedded parts 1, thereby avoiding the influence of the displacement of the steel bars 8 during the subsequent steel bar 8 tying operation, reducing the secondary adjustment of the base elevation, horizontal position, and horizontality before the installation of the steel column, ensuring the installation accuracy of the steel column, and saving manpower, material resources and construction period.

[0031] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
