Description

Technical Field

[0001] This utility model belongs to the field of steel structure building technology, specifically relating to a through-sleeve and a steel beam-steel pipe column connection node using the through-sleeve. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In steel structure construction, quality control of bolted connections is relatively simple, requiring only torque or tension checks. Welding, on the other hand, demands higher levels of worker skill and environmental conditions, necessitating strict quality control. Furthermore, bolted connections easily connect different materials, offering wider adaptability. Therefore, bolted connections are more suitable for connecting dissimilar materials and for structures requiring high flexibility and reliability. However, in steel structures, steel beam-concrete composite column joints are difficult to bolt, primarily because the closed cross-section of the steel column limits the bolt's operating space, making standard installation methods difficult to implement. Even with holes, the limited space makes bolt tool operation difficult. Moreover, even if bolted connections are achieved, after concrete pouring, the bolts cannot be disassembled and reinstalled, leading to significant difficulties in subsequent maintenance. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a through-sleeve and a steel beam-steel pipe column connection node using the through-sleeve, which solves the problem that existing steel pipe concrete column and steel beam connection nodes cannot be connected by bolts, and can be easily disassembled after installation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] In a first aspect, this utility model provides a through-hole sleeve structure, comprising: a steel pipe column, wherein two sets of circular through holes are arranged opposite to each other on two opposite side walls of the steel pipe column, each set including multiple through holes; the through holes of one set correspond one-to-one with the through holes of the other set and are arranged coaxially, and a through-hole threaded sleeve is installed in each coaxially arranged through hole; the through-hole threaded sleeve is a circular tubular component, and the through-hole threaded sleeve is provided with a full thread inside.

[0007] Furthermore, each set of through holes is arranged in a rectangular array on the side wall of the steel pipe column; the diameter of the outer wall of the circular tubular member is smaller than the diameter of the through hole, and the length of the circular tubular member is equal to the distance between the two opposite outer walls of the steel pipe column.

[0008] Alternatively, a through-sleeve structure includes: a steel pipe column, on which two sets of regular hexagonal through holes are arranged opposite each other, and respectively on two opposite side walls of the steel pipe column, each set including multiple through holes; the through holes of one set correspond one-to-one with the through holes of the other set and are arranged coaxially, and a through-threaded sleeve is installed in each coaxially arranged through hole; the through-threaded sleeve is a regular hexagonal tubular component, and the through-threaded sleeve is provided with full threads inside.

[0009] Furthermore, each set of through holes is arranged in a rectangular array on the side wall of the steel pipe column; the diameter of the circumcircle of the regular hexagonal tubular member is smaller than the diameter of the circumcircle of the through hole, and the length of the regular hexagonal tubular member is equal to the distance between the two opposite outer side walls of the steel pipe column.

[0010] Alternatively, a through-sleeve structure includes: a steel pipe column, on which two sets of circular through holes are arranged opposite each other, and respectively disposed on two opposite side walls of the steel pipe column. Each set includes multiple through holes, and each through hole is provided with an internal thread; the through holes of one set correspond one-to-one with the through holes of the other set and are arranged coaxially, and a through-threaded sleeve is installed in each coaxially arranged through hole; the through-threaded sleeve is a circular tubular component, and the inside of the through-threaded sleeve is provided with a full thread, and both ends of the outer side wall of the circular tubular component are provided with external threads for engaging with the internal threads in the through holes.

[0011] Furthermore, each set of through holes is arranged in a rectangular array on the side wall of the steel pipe column; the parameters of the external thread on the circular tubular member are the same as the parameters of the internal thread of the through hole, and the length of the circular tubular member is equal to the distance between the two opposite outer side walls of the steel pipe column.

[0012] Secondly, this utility model also provides a steel beam-steel pipe column connection node utilizing a through-sleeve, comprising: the aforementioned through-sleeve structure, a steel beam, and connecting fasteners; the steel beam includes an H-beam and an end plate, the end plate being fixedly disposed at the end of the H-beam, the end plate having a connecting hole, the diameter of the connecting hole being larger than the nominal diameter of the full thread inside the through-sleeve and smaller than the diameter of the through-sleeve or the diameter of its circumscribed circle; an H-beam is respectively installed on each of the two side walls of the steel pipe column, the end of the H-beam being connected to the full thread inside the through-sleeve via a connector.

[0013] Furthermore, concrete is poured into the steel pipe column to anchor the through-threaded sleeve in the steel pipe column.

[0014] Furthermore, the arrangement of the connecting holes on the end plate is the same as the arrangement of the through holes on one of the side walls of the steel pipe column, and the center distance between adjacent through holes is equal to the center distance between adjacent connecting holes.

[0015] Furthermore, the connecting component is a high-strength bolt; the through-threaded sleeve is made of high-strength steel.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are:

[0017] All connection nodes of this utility model are connected by bolts, replacing the traditional welding method, which improves the construction speed and quality. The construction method is simple, easy to operate, and improves construction efficiency. The connection nodes are symmetrical on both sides, and the tension or pressure generated at the end of the steel beam will also be symmetrically transmitted to the threaded sleeve through the bolts. At this time, most of the external load borne by the sleeve itself can be canceled out, so that no additional load is generated on the steel tube concrete column, which enhances the load resistance of the entire frame structure.

[0018] All components of this invention are prefabricated in the factory without welding, and on-site assembly also requires no welding, achieving a fully prefabricated processing procedure. The construction process is green and environmentally friendly, ensuring component quality, improving construction efficiency, and greatly enhancing the level of prefabrication. The structure formed by the construction method can be connected using ordinary high-strength bolts, which not only solves the problem of the difficulty in connecting steel pipe column nodes with bolts, but also allows the bolts to be removed after construction for building maintenance.

[0038] Example 4

[0039] This embodiment provides a steel beam-steel pipe column connection node utilizing a through-sleeve, such as... Figures 1-6As shown, it includes: a through-sleeve structure for a steel pipe column 2 as described above, as well as a steel beam 4 and connecting fasteners; the steel beam 4 includes an H-beam 41 and an end plate 42, the end plate 42 is fixedly disposed at the end of the H-beam 41, the end plate 42 is provided with a connecting hole, the diameter of the connecting hole is larger than the nominal diameter of the full thread 11 inside the through-thread sleeve 1, and smaller than the diameter of the through-thread sleeve 1 or the diameter of its circumscribed circle; an H-beam 41 is respectively installed on each of the two side walls of the steel pipe column 2, and the end of the H-beam 41 is connected to the full thread 11 inside the through-thread sleeve 1 through a connector 3.

[0043] The construction process of the connection node is as follows:

[0044] First, the components are pre-processed in the factory, including opening through holes 21 on the two opposite side walls of the steel pipe column 2 and connecting holes on the end plate 42; then the end plate 42 is welded to the H-beam 41 to form a whole; then it is installed on the construction site. After the steel pipe column 2 is fixed, the threaded sleeve 1 is horizontally inserted into the steel pipe column 2, so that the two ends of the threaded sleeve 1 fall into the corresponding through holes 21 on the two sides of the steel pipe column 2. After checking that there is no exposed threaded sleeve 1 on the two side walls of the steel pipe column 2, the position of the threaded sleeve 1 is initially fixed by injecting epoxy resin.

[0045] Then, the steel beam 4 is hoisted, aligning the connecting holes on the end plate 42 with the center line of the through holes 21 on the steel pipe column 2, and then fixed using the connectors 3. When installing the connectors 3, first manually tighten all the connectors 3 on one side of the steel beam 4, and then install the connectors 3 by manually tightening them as well, for initial fixing. Then, using a torque wrench or electric wrench, apply the specified preload to all the connecting bolts according to the specifications to complete the final tightening, and then remove the hoisting equipment from the steel beam 4.

[0046] Finally, concrete is pumped into the steel pipe column 2, and then cured to complete the construction process.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
