[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0035] See also Figure 1-5 The utility model discloses an assembled steel column butt joint auxiliary connector, which is used to assist the lifting and alignment of a lower steel column 01 and an upper steel column 02, and includes:
[0036] Connector 1, which is an L-shaped steel plate that fits the inner walls of the lower steel column 01 and the upper steel column 02;
[0037] The lower steel column 01 and the upper steel column 02 are both provided with connection bolt holes 03;
[0038] The connecting member 1 includes a guide section 11 and a connecting section 12 distributed up and down;
[0039] The guide section 11 is offset away from the inner wall side of the lower steel column 01 and the upper steel column 02 to guide the upper steel column 02 to dock;
[0040] The connecting section 12 is provided with locking bolt holes 13 corresponding to the connecting bolt holes 03 for connecting with the lower steel column 01 and the upper steel column 02 .
[0041] It also includes a fixing bolt 2, which is used to penetrate the connecting bolt hole 03 and the locking bolt hole 13 to preliminarily fix the lower steel column 01 and the upper steel column 02.
[0042] When the present application is used, during the prefabrication process in the factory, the connecting section 12 of the connecting member 1 can be firstly arranged in the lower steel column 01, and after the connecting bolt hole 03 and the locking bolt hole 13 are aligned, the two can be fixed by the fixing bolt 2;
[0043] Then, during on-site construction, the upper steel column 02 is transported to the top of the lower steel column 01 by means of lifting equipment, and then the upper steel column 02 is lowered and connected to the guide section 11 of the connector 1. The guide section 11 guides the lifting and alignment process, assists in the quick connection of the upper steel column 02 and the lower steel column 01, and then the connector 1 and the upper steel column 02 are connected by means of fixing bolts 2, so as to achieve the purpose of quickly completing the lifting and docking of the upper steel column 02 and the lower steel column 01. The construction is quick and convenient, which can greatly save the steel structure prefabricated building period.
[0044] It should be further explained that the connecting bolt hole 03 provided on the upper steel column 02 is an elliptical bolt hole. The elliptical bolt hole is provided to provide redundancy to avoid deviation after the upper steel column 02 and the lower steel column 01 are docked, resulting in the connecting bolt hole 03 and the locking bolt hole 13 not being completely corresponding, thereby affecting the normal setting of the fixing bolt 2.
[0045] An embodiment that needs to be explained is that the connecting section 12 of the connecting member 1 is welded to the lower steel column 01. During the factory prefabrication process, the connecting section 12 of the connecting member 1 can be first set in the lower steel column 01, and after the connecting bolt hole 03 and the locking bolt hole 13 are aligned, the two are fixed by welding.
[0046] Another embodiment that needs to be explained in the present application is that an elastic resistance member 3 is provided at the locking bolt hole 13 on the connecting member 1;
[0047] The elastic resisting member 3 is provided with a telescopic latch 31 penetrating through the locking bolt hole 13 and a resisting spring 32 for resisting the telescopic latch 31;
[0048] The telescopic bayonet 31 is provided with a tilting block 311, and the tilting block 311 is used to shrink when the telescopic bayonet 31 contacts the lower steel column 01;
[0049] The resisting spring 32 is used to push the telescopic bayonet 31 to be engaged in the connecting bolt hole 03 to fix the lower steel column 01 when the connecting bolt hole 03 and the locking bolt hole 13 correspond to each other.
[0050] The above-mentioned structural arrangement is for the purpose of setting the connecting section 12 of the auxiliary connecting member 1 in the lower steel column 01 during the factory prefabrication process. When in use, the connecting member 1 can be directly pushed into the lower steel column 01 until the connecting bolt hole 03 and the locking bolt hole 13 correspond. The resistance spring 32 pushes the telescopic bayonet 31 to be engaged in the connecting bolt hole 03, so that the connecting member 1 and the lower steel column 01 are initially fixed, thereby saving the calibration process of manually placing the connecting member 1, and being able to avoid the connecting member 1 from falling into the lower steel column 01, thereby improving the production and processing efficiency.
[0051] It should be noted that the elastic abutment member 3 is provided with a contraction cavity 33 corresponding to the fixing bolt 2;
[0052] When the fixing bolt 2 penetrates the connecting bolt hole 03 and the locking bolt hole 13 , it extends into the contraction cavity 33 and pushes the telescopic bayonet 31 to contract.
[0053] In the present application, there are two groups of elastic resistance members 3, which are arranged perpendicularly to each other and fixedly connected to the connecting member 1. The two groups of elastic resistance members 3 can effectively improve the installation accuracy of the connecting member 1 and the lower steel column 01 and avoid displacement during the installation process.
[0054] Furthermore, the lengths of the two groups of elastic resistance members 3 correspond to the length and width of the inner wall of the lower steel column 01 respectively. The length of the elastic resistance members 3 is adapted to the inner wall of the lower steel column 01, which can effectively prevent the connecting member 1 from falling into the lower steel column 01.
[0055] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0056] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0057] In addition, "plurality" means two or more.
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
