Description

Technical Field

[0001] This utility model relates to the field of building steel structure connection technology, and in particular to the construction of a sleeve-insertion type steel column base connection node. Background Technology

[0002] In current technology, steel structure buildings are becoming increasingly common. Composed of steel columns, steel beams, and various steel components, they are widely used in lightweight buildings, large-span houses, landscape features, structures, residences, office buildings, and other applications. Due to their ease of construction, light weight, and good seismic performance, steel structures are widely used. Corresponding national codes and standards are also relatively complete, ensuring safety, reliability, and practicality.

[0003] In steel structures, various connections are particularly important and place higher demands on the construction site. The connection between the common steel column and the concrete foundation is a problem that most steel structure connections will encounter. Common practices include pre-embedded anchors, on-site welding, and embedded installation, which are relatively convenient and reliable when conditions permit. However, when there are situations where pre-embedded parts cannot be placed later or the steel column cannot be installed in one go, the on-site installation requirements are usually not met.

[0004] Therefore, how to optimize the connection node between the steel column and the concrete foundation to make the construction and installation easier while ensuring structural safety has become a technical problem that technicians in this field urgently need to solve. Utility Model Content

[0008] The steel sleeve is fixed to the side of the embedded steel plate facing away from the concrete foundation.

[0009] The steel sleeve includes a mounting hole that matches the end of the steel column, through which one end of the steel column is nested;

[0010] The end of the steel column is nested inside the steel sleeve, and the outer wall of the corresponding suspended end of the steel sleeve is fixed to the steel sleeve by welding.

[0011] Preferably, the steel column is cylindrical.

[0012] Preferably, the embedded steel plate, all the anchor bars, and the steel sleeve are an integral part, and are fixed by welding during factory manufacturing.

[0013] Preferably, the number of anchor bars connected to the pre-embedded steel plate is no less than four.

[0014] Preferably, each of the anchor bars has a 90-degree hook structure with a length of 4 times at one end embedded in the concrete foundation.

[0015] Preferably, each of the anchor bars and the embedded steel plate is connected by pressure submerged arc welding or through-hole plug welding.

[0016] Preferably, the inner diameter of the steel sleeve is 1 mm to 2 mm larger than the outer diameter of the steel column.

[0017] Preferably, the embedded steel plate, the steel sleeve, and the steel column are all made of Q235B or Q355B material.

[0018] The beneficial effects of this utility model are:

[0019] The application of this utility model optimizes the structure of the steel column base connection node, making it easier to process, manufacture, and install while ensuring structural safety.

[0026] Example

[0027] like Figures 1 to 4 As shown, the sleeve-insertion type steel column base connection node structure includes a steel structure embedded part 2 fixed to the concrete foundation 1, and a steel column 4 fixed to the steel structure embedded part 2 by a steel sleeve 3.

[0028] Among them, the steel structure embedded part 2 includes an embedded steel plate 21 set on the surface of the concrete foundation 1, and a number of anchor bars 22 embedded in the concrete foundation 1 and connected to the embedded steel plate 21.

[0029] The steel sleeve 3 is fixed to the side of the embedded steel plate 21 facing away from the concrete foundation 1;

[0030] The steel sleeve 3 includes a mounting hole that matches the end of the steel column 4, through which one end of the steel column 4 is nested;

[0031] The end of the steel column 4 is nested inside the steel sleeve 3, and the outer wall of the corresponding suspended end of the steel sleeve 3 is fixed to the steel sleeve 3 by welding.

[0032] This invention achieves overall fixation by inserting the steel column 4 into the steel sleeve 3 on-site and welding it to the embedded part 2 of the steel structure. This makes the processing, fabrication, construction, and installation convenient, quick, safe, and reliable.

[0033] In practical applications, the length of the anchor bar 22 should meet the anchorage length requirements of the specification, and the thickness of the anchor plate 21 should meet the calculation requirements and construction requirements.

[0034] In some embodiments, the steel column 4 is cylindrical.

[0035] In some embodiments, the embedded steel plate 21, all anchor bars 22, and steel sleeve 3 are an integral part and are fixed by welding during factory manufacturing.

[0036] In some embodiments, the pre-embedded steel plate 21 is connected to no fewer than four anchor bars 22.

[0037] In some embodiments, each anchor bar 22 is provided with a 90-degree hook structure with a length of 4 times at one end embedded in the concrete foundation 1.

[0038] In some embodiments, each anchor bar 22 is connected to the embedded steel plate 21 by pressure submerged arc welding or through-hole plug welding.

[0039] In practical applications, the choice between pressure submerged arc welding or through-hole plug welding is determined based on the connection dimensions between the anchor bar 22 and the anchor plate 21.

[0040] In some embodiments, the inner diameter of the steel sleeve 3 is 1 mm to 2 mm larger than the outer diameter of the steel column 4.

[0041] In practical applications, the inner diameter of the steel sleeve 3 is 1mm to 2mm larger than the outer diameter of the steel column 4, which allows the round steel column 4 to be inserted more tightly.

[0042] The embedded steel plate 21, steel sleeve 3 and steel column 4 are all made of Q235B or Q355B material.

[0043] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
