However, in the steel sinking well construction process, the steel sinking well main structure provides a limited column bottom support surface for the steel pipe column, and the grouting pipe laying problem during the steel sinking well filling needs to be considered. In addition, the steel pipe column is high in the steel sinking well, and the upper load is complex and changeable. These all put forward higher requirements for the structure of the steel pipe column. The structure of the traditional steel pipe support column is generally in the form of a column top slot or a column cap to place the distribution beam of the construction platform, and the column bottom is inserted into the foundation or directly supported on the ground. This structure is simple and thin in connection, and obviously cannot meet the platform support in the complex structure such as steel sinking well. SUMMARY

[0003] The main technical problem to be solved by the utility model is to provide a platform support column which can stably support the upper construction platform in the steel sinking well and can be used as a pipe laying channel for concrete grouting pipe.

[0007] The base is a rigid space structure composed of several steel plates; the base is fixedly connected to the outer periphery of the bottom of the column body; the bottom of the base is fixedly connected to the bottom structure;

[0008] The supporting part is fixed to the top outer periphery of the column body and extends outward to support the distribution beam at the bottom of the construction platform.

[0010] In a preferred embodiment, the base further includes stiffening plates; a plurality of stiffening plates are spaced apart on the top of the ring plate along the circumferential direction of the column; the stiffening plates are simultaneously welded perpendicularly to both the column and the ring plate.

[0011] In a preferred embodiment, the supporting beam is a "well"-shaped structure welded from several I-beams.

[0012] In a preferred embodiment, a plurality of limiting members extend upward from the top of the support portion; the plurality of limiting members are spaced apart in the beam width direction of the distribution beam to limit and cooperate with the distribution beam.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In addition, the term "first", "second" is only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the utility model, it needs to explain, unless otherwise explicitly provided and limited, the term "installation", "set with", "sleeve set / interface", "connection" and so on, should be broad understanding, for example "connection", can be wall-mounted connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through intermediate medium, can be the communication inside two elements, for ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0031] As Figs. 1-6 The utility model discloses a platform support column 1 that is used as concrete pouring channel simultaneously, the support column 1 is arranged at the top of steel caisson compartment 2 to support the construction platform 3 at the top of steel caisson. Meanwhile, the support column 1 is through in the inside, and the concrete pipe channel for filling the steel caisson compartment 2 is provided. Therefore, in the embodiment, the "bottom structure" in the claim is the steel caisson compartment 2. The support column 1 includes column body 11, base 12 and supporting part 13. Overall, the column body 11 is vertically installed at the top of the steel caisson compartment 2 through the base 12, and the supporting part 13 is fixedly connected at the top of the column body 11 to support the construction platform 3. Now, the components and connection relationship of the support column 1 will be further described with reference to the drawings.

[0032] The column body 11 adopts a steel pipe through in the middle, and the inner diameter is not less than the outer diameter of concrete grouting guide pipe (hereinafter referred to as "guide pipe"). In order to further facilitate pipe running, the top of the column body 11 is flush with the top of the construction platform 3. As Figs. 1-4As shown, the bottom of the column 11 is vertically welded to the sealing plate 21 on top of the steel caisson compartment 2. As an existing structure, the sealing plate 21 has a grouting hole 211 in its central area. Therefore, the inner diameter of the column 11 should not be less than the diameter of the grouting hole 211, and the projection area on the sealing plate 21 should encompass the grouting hole 211. Since the load transmitted from the upper construction platform 3 to the supporting column 1 is complex and variable, relying solely on the welded connection between the column 11 and the sealing plate 21 to transfer the load not only lacks sufficient lateral stiffness but also causes stress concentration at the bottom of the column 11, resulting in a strong punching shearing effect on the sealing plate 21, thus affecting the service life of the structure. To improve the connection strength and structural stability, a base 12 is also provided at the bottom of the supporting column 1.

[0033] The essential features of the base 12 are: structurally, the base 12 is a rigid spatial structure welded from several steel plates, possessing high vertical and lateral stiffness; in terms of connection, the base 12 is welded around the periphery of the column 11, and its bottom is welded to the sealing plate 21. Fig. 4 As shown, in this embodiment, the base 12 includes a supporting beam 121, a ring plate 122, and stiffening plates 123. The supporting beam 121 is a "well"-shaped structure formed by cross-welding of several steel components, possessing high vertical stiffness. In this embodiment, the steel components are I-beams. The supporting beam 121 surrounds the periphery of the column 11 and is welded to the top of the sealing plate 21. The ring plate 122 is horizontally and tightly welded around the outer periphery of the column 11. The ring plate 122 extends away from the column 11 to be welded to the top of the supporting beam 121. Several stiffening plates 123 are spaced apart on the top of the ring plate 122 along the circumferential direction of the column 11. Specifically, a single stiffening plate 123 is vertically arranged and welded perpendicularly to both the column 11 and the ring plate 122 in the diameter direction of the column 11. Based on this connection, the base 12, through the bridging effect of the stiffening plate 123 and the ring plate 122, transmits the lateral force from the column 11 to the supporting beam 121, thereby improving the lateral stability of the column 11. Furthermore, the base 12 also distributes some of the vertical force of the column 11 onto the I-beams, greatly reducing the shearing effect of the column 11 on the sealing plate 21.

[0034] It is not difficult to understand that the "well"-shaped structure is not a limitation on the supporting beam 121. In other embodiments, the supporting beam 121 can be constructed as a triangular structure or as a radial structure resembling a gas stove bracket. In a further structural upgrade, the combined structure of the supporting beam 121 and the ring plate 122 can also be replaced by a single thick steel plate. In this alternative, the thick steel plate is welded around the outer periphery of the column 11 and welded to the sealing plate 21 at the bottom. The stiffening plate 123 is welded between the column 11 and the thick steel plate. Furthermore, the base 12 can also be a cylindrical structure welded from several circular horizontal plates and radial vertical plates, with its center welded around the outer periphery of the column 11 and its bottom welded to the sealing plate 21, which can also improve the connection strength between the column 11 and the sealing plate 21.

[0035] The main body of the support portion 13 is a bracket 131. The bracket 131 is a rigid spatial structure welded from several steel plates, possessing high vertical stiffness. For example... Figs. 5-6 As shown, two brackets 131 are welded to the outer periphery of the top of the column 11 and extend outward along the diameter of the column 11. As mature existing technology, the connection relationship between the brackets 131 and the column 11 will not be elaborated upon here. It should be noted that the brackets 131 serve to support the distribution beam 31 at the bottom of the construction platform 3; therefore, the extension direction of the brackets 131 is perpendicular to the distribution beam 31. Furthermore, the height difference between the top of the bracket 131 and the bottom of the column 11 should match the height difference between the distribution beam 31 and the sealing plate 21. As shown in the figure, several limiting members 1311 extend upward from the top of the bracket 131 to limit the distribution beam 31. Specifically, at the top of each bracket 131, two limiting members 1311 are spaced apart in the extension direction of the bracket 131, i.e., in the width direction of the distribution beam 31, and the spacing is equal to the beam width of the distribution beam 31. In this way, the limiting member 1311 can be matched with the distribution beam 31 along the beam width direction to limit the latter from sliding off the top of the bracket 131. The support part 13 also includes several reinforcing plates 132. The reinforcing plates 132 are horizontally arranged and welded to the column 11 and the brackets 131 on both sides of the column 11. Within the height range of the brackets 131, several reinforcing plates 132 are arranged at intervals in the vertical direction. The reinforcing plates 132 distribute the load between the column 11 and the brackets 131 to more connecting welds, thereby greatly reducing the strength requirement of a single weld and improving the integrity and load-bearing limit of the support part 13.

[0036] In the embodiment, the column 11, the base 12 and the support part 13 are all made of Q235B steel. Specifically, the column 11 is made of a round steel pipe with an outer diameter of 630 mm and a wall thickness of 12 mm; in the base 12, the beam 121 is made of an HN600mmx200mm I-beam, the ring plate 122 and the ring plate are made of 20 mm thick steel plates; in the support part 13, the corbel 131 and the reinforcing plate 132 are both made of 20 mm thick steel plates.

[0037] In the connection relationship of the components, the internal and external connection of the support column 1 does not rely on welding alone. In other embodiments, bolts can be pre-buried on the blocking plate 21, and the column 11 and the beam 121 are fixedly connected with the blocking plate 21 through threaded fasteners. For example, the corbel 131 and the column 11 can also be fixedly connected through a plurality of threaded fasteners arranged at intervals in the height direction. As a common prior art, this will not be described here.

[0038] Now the installation and manufacturing process of the support column 1 will be briefly described. The installation and manufacturing process includes the following steps: S1, welding the beam 121 on the blocking plate 21 around the grouting hole 211; S2, hoisting and positioning the column 11 to the outer periphery of the grouting hole 211, and then full-welding the column 11 and the blocking plate 21; S3, welding the ring plate 122 on the outer periphery of the column 11 and the top of the beam 121; S4, welding the stiffening plate 123 along the circumferential direction of the column 11; S5, according to the height difference between the construction platform 3 and the blocking plate 21, welding the corbel 131 on the top of the column 11, and welding each layer of the reinforcing plate 132 in the height direction. In the above steps, S1 and S2 are not sequential.

[0039] The use method of the support column 1 is: after the support column 1 is welded on the top of the blocking plate 21, the distribution beam 31 at the bottom of the construction platform 3 is placed between the limit members 1311 on the top of the corbel 131. Then, the concrete grouting pipe is inserted from the top of the column and extends into the steel caisson compartment 2 from the grouting hole 211 on the top of the blocking plate 21.

[0040] In summary, the support column 1 provided by the embodiment of the utility model in function not only realizes reliable support to the construction platform 3, but also serves as a pipe channel of the concrete grouting guide pipe, avoids the problem of guide pipe deflection and zigzagging caused by excessive height difference in the prior construction, improves the installation precision of the guide pipe, and further improves the filling efficiency of the concrete. This innovative idea of improving the construction efficiency by double utilization of the force bearing member has high technical inspiration and engineering promotion value. In structure, the base 12 not only improves the lateral stiffness of the column body 11 at the foot, but also distributes the load transmitted by the column body 11 to the blocking plate 21, avoids stress concentration at the connection, and greatly reduces the punching action on the blocking plate 21. Secondly, the corbels 131 are relatively arranged at the outer periphery of the column body 11 to avoid eccentric force of the column body 11, and the reinforcing plates 132 are used to improve the connection strength between the corbels 131 and the column body 11. The above two structural designs improve the connection stability and bearing capacity of the support column 1, so that it can still work stably under complex and variable upper loads.

[0041] The above is only the preferred specific embodiment of the utility model, and is not limited to the patent range of the utility model, and any equivalent transformation of the technical content in the utility model specification belongs to the protection range of the utility model.
