Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to a quick connection device for wall column bases in building structures. Background Technology

[0002] In a building structure system, the connection point between vertical load-bearing components (such as columns and shear walls) and the foundation, namely the "wall-column foot", is the necessary path for the transmission of force. It safely transfers the vertical loads (dead loads and live loads), horizontal loads (wind loads and seismic forces) and bending moments borne by the superstructure to the foundation. A well-designed, properly constructed, and precisely installed wall-column foot connection is a prerequisite for ensuring that the building is "deeply rooted".

[0003] The wall and column base structure mainly includes steel beams, foundation, anchor bolts and column base plates. The anchor bolts are buried in the foundation, the column base plates are placed on the foundation and restrained by the anchor bolts, and then the steel beams are stacked on the column base plates and fixed with anchor bolts and nuts.

[0004] When installing wall column bases, a crane is first used to lift the steel beam above the foundation and column base plate. Then, ground workers guide the steel beam to accurately insert the anchor bolts into the anchor bolt holes. However, this installation method has some drawbacks, such as:

[0005] The diameter of the anchor bolt hole in the steel beam cannot exceed the diameter of the nut or nut washer. Therefore, there is a limitation on the size of the anchor bolt hole, which makes it difficult for workers to quickly and accurately align the anchor bolt with the anchor bolt hole when guiding the steel beam. In other words, the existing wall column base structure is not convenient to install.

[0006] Therefore, this utility model provides a quick connection device for wall column bases in building structures to solve the above problems. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model provides a quick connection device for wall column bases in building structures, so as to solve the problem that workers have difficulty quickly and accurately aligning anchor bolts with anchor bolt holes when guiding steel beams.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A quick-connection device for wall column bases in building structures includes steel beams, an intermediate layer plate, and a foundation;

[0010] Foundation: Anchor bolt assemblies are embedded in the foundation;

[0011] Middle layer plate: The middle layer plate is stacked on the upper side of the foundation and fixed by the anchor bolt group. The upper side of the middle layer plate has an integrally formed inner plug. The upper end of the inner plug is set as an inclined surface and the lower end of the inclined surface is higher than the upper end of the anchor bolt group.

[0012] Steel beams: Steel beams are stacked on the upper side of the middle plate and fixed by anchor bolts. Inclined panels are welded to the side of the steel beams. The upper end of the inclined panels is provided with an inclined part, and the lower end of the inclined part is higher than the upper end of the anchor bolt group. The inclined part of the inclined panels is stacked on the inclined surface of the inner plug.

[0013] Through the above technical solution, the anchor bolt assembly fixes the middle layer plate and steel beam to the foundation, realizing the conventional installation and connection function. The upper end of the inner plug is inclined, making the upper end of the inner plug conical, which facilitates the insertion of the inner plug under the inclined panel of the steel beam. Furthermore, the lower end height of the inclined surface of the inner plug and the lower end height of the inclined part of the inclined panel are higher than the upper end height of the anchor bolt assembly. When the inclined panel falls on the inner plug, the upper end of the inclined panel slides relative to the upper end of the inner plug, allowing the inner plug to be accurately inserted into the inclined panel. This enables the middle layer plate and steel beam to be aligned. In other words, the cooperation of the inclined panel and the inner plug assists the workers in guiding the steel beam for positioning and alignment, enabling faster and more convenient installation of the steel beam.

[0014] Preferably, the anchor bolt assembly includes a first nut, a first anchor bolt, a second nut, and a second anchor bolt. The lower ends of the first anchor bolt and the second anchor bolt are both fixedly embedded in the foundation. There are four first anchor bolts, which are located at the four corners of the center of the foundation. There are four second anchor bolts, which are located at the four sides of the center of the foundation. The first anchor bolt is threaded with a first nut, and the second anchor bolt is threaded with a second nut.

[0015] The first anchor bolt passes through the four corners of the middle layer plate and the steel beam and is then secured with the first nut;

[0016] The first and second anchor bolts are at the same height and both are lower than the lower end of the inclined surface of the inner insert and the lower end of the inclined portion of the inclined panel.

[0017] The above technical solution secures the four corners of the middle layer plate and the steel beam with the first anchor bolt and the first nut.

[0018] Preferably, a lower mesh plate is sandwiched between the middle layer plate and the foundation. The lower mesh plate is made of steel, and the first anchor bolt passes through the four corners of the lower mesh plate.

[0019] With the above technical solution, when there are soil particles on the foundation, the lower mesh plate can crush the soil particles, and the crushed soil particles fall into the holes of the lower mesh plate, thus avoiding soil particles being trapped between the middle plate and the foundation, which would cause the middle plate to tilt and improve the flatness between the foundation and the middle plate.

[0020] Preferably, the upper periphery of the lower mesh plate is provided with a stepped groove, and the periphery of the middle layer plate is inserted downward into the stepped groove;

[0021] The above technical solution confines the lower mesh plate within the middle layer plate, making the lower mesh plate and the middle layer plate fit together more closely, preventing the lower mesh plate from shifting relative to the middle layer plate, and making the installation structure more robust.

[0022] Preferably, the upper periphery of the lower mesh plate is integrally formed with a connecting post, and the middle of the inner plug is a hollow structure, so that the connecting post is located in the middle of the inner plug, and the second anchor bolt passes through the connecting post and is fixed with the second nut.

[0023] With the above technical solution, the second anchor bolt passes through the connecting column and is fixed with the second nut, thus fixing the connecting column and the lower mesh plate, making the installation structure more reliable.

[0024] Preferably, both the side of the inclined panel and the side of the inner plug are provided with notches, the lower height of the notches is equal to the upper height of the connecting column, an auxiliary fixing bracket is placed between the inclined panel, the inner plug and the connecting column, the auxiliary fixing bracket passes through the notches of the inclined panel and the inner plug and covers the upper side of the connecting column, the second anchor bolt passes through the auxiliary fixing bracket, and a fixing screw is threaded through the end of the auxiliary fixing bracket, between the inclined panel and the inner plug.

[0025] The above technical solution uses auxiliary fixing frames to connect the inclined panels, internal inserts, and connecting columns together, and fixes the four sides of the lower mesh plate, middle plate, and steel beam. By improving the installation stability of the inclined panels, internal inserts, and connecting columns, the connection stability of the foundation, lower mesh plate, middle plate, and steel beam is further improved, making the installation structure more reliable.

[0026] The beneficial effects of this utility model are as follows:

[0027] In summary, this device can fix the lower mesh plate, middle plate, and steel beam to the foundation from the four corners and four sides of the steel beam using anchor bolts, achieving conventional installation and connection functions and ensuring a stable installation structure.

[0028] Furthermore, the lower end height of the inclined surface of the inner plug and the lower end height of the inclined part of the inclined plate are higher than the upper end height of the anchor bolt assembly. When the inclined plate falls on the inner plug, the upper end of the inclined plate slides relative to the upper end of the inner plug, allowing the inner plug to be accurately inserted into the inclined plate. This enables the middle layer plate and the steel beam to be aligned. That is, even when the first and second anchor bolts are not inserted into the anchor bolt holes of the steel beam, the cooperation of the inclined plate and the inner plug helps the workers guide the steel beam to be positioned and aligned, making the installation of the steel beam faster and more convenient.

[0035] The following will refer to the attached reference. Figures 1 to 5 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0036] As attached Figure 1 -Appendix Figure 5 As shown, a quick connection device for wall column bases in building structures includes a steel beam 1, a lower mesh plate 8, a middle plate 5, and a foundation 9;

[0037] Foundation 9: An anchor bolt assembly is embedded in foundation 9. The anchor bolt assembly includes a first nut 10, a first anchor bolt 11, a second nut 12, and a second anchor bolt 13. See Appendix. Figure 3 and attached Figure 5 There are four first anchor bolts 11 and four second anchor bolts 13, and their lower ends are fixedly buried in the foundation 9. The four first anchor bolts 11 are located at the four corners of the center of the foundation 9, and the four second anchor bolts 13 are located at the four sides of the center of the foundation 9. The first anchor bolt 11 is threaded with a first nut 10, and the second anchor bolt 13 is threaded with a second nut 12.

[0038] Lower layer mesh panel 8: See appendix Figure 1 and attached Figure 4 The lower mesh plate 8 is stacked on the upper side of the foundation 9. The lower mesh plate 8 is made of steel. The first anchor bolt 11 passes through the four corners of the lower mesh plate 8. The upper periphery of the lower mesh plate 8 is provided with a stepped groove 14. The upper periphery of the lower mesh plate 8 is integrally formed with a connecting column 7. The second anchor bolt 13 passes through the connecting column 7.

[0039] Middle layer 5: See Appendix Figure 1 -Appendix Figure 3 The middle layer plate 5 is also made of steel. The middle layer plate 5 is stacked on the upper side of the lower mesh plate 8. The periphery of the middle layer plate 5 is inserted into the stepped groove 14. The upper side of the middle layer plate 5 is integrally formed with an inner plug 6. The middle of the inner plug 6 is a hollow structure, so that the connecting column 7 is located in the middle of the inner plug 6. The upper end of the inner plug 6 is set as an inclined surface and the lower end of the inclined surface is higher than the upper end of the first anchor bolt 11 and the second anchor bolt 13. The four first anchor bolts 11 pass through the four corners of the middle layer plate 5 respectively.

[0040] Steel Beam 1: See Appendix Figure 1 -Appendix Figure 3 The steel beam 1 is stacked on the upper side of the middle plate 5. Two symmetrical inclined plates 2 are welded and fixed on the four sides of the steel beam 1. The upper end of the inclined plate 2 is provided with an inclined part, and the lower end of the inclined part is higher than the upper end of the first anchor bolt 11 and the second anchor bolt 13. The inclined part of the inclined plate 2 is stacked on the inclined surface of the inner plug 6, that is, the inner plug 6 is inserted upward into the inclined plate 2. The four first anchor bolts 11 pass through the four corners of the steel beam 1 respectively, and then the first nut 10 is screwed into the upper end of the first anchor bolt 11.

[0041] In summary, after the first anchor bolt 11 passes through the lower mesh plate 8, the middle plate 5 and the steel beam 1, the first nut 10 is screwed on. After the first nut 10 is tightened, it clamps the lower mesh plate 8, the middle plate 5 and the steel beam 1 for fixation.

[0042] Both the side of the inclined panel 2 and the side of the inner plug 6 are provided with notches. The lower height of the notch is equal to the upper height of the connecting post 7. An auxiliary fixing bracket 4 is placed between the inclined panel 2, the inner plug 6 and the connecting post 7. The auxiliary fixing bracket 4 passes through the notch of the inclined panel 2 and the inner plug 6 and covers the upper side of the connecting post 7. The second anchor bolt 13 passes through the auxiliary fixing bracket 4 and is fixed with the second nut 12. A fixing screw 3 is threaded through the end of the auxiliary fixing bracket 4 and between the inclined panel 2 and the inner plug 6.

[0043] The working principle of this device is as follows:

[0044] During installation, the lower mesh plate 8 is first placed on the foundation 9, with the first anchor bolt 11 passing through the lower mesh plate 8 and the second anchor bolt 13 passing through the connecting column 7. Then, the middle layer plate 5 is placed on the lower mesh plate 8, with the first anchor bolt 11 passing through the middle layer plate 5. The connecting column 7 is located inside the inner insert 6. Finally, the steel beam 1 is hoisted above the inner insert 6. Because the lower end of the inclined section of the inclined panel 2 is higher than the upper end of the first anchor bolt 11 and the second anchor bolt 13, and the lower end of the inclined surface of the inner insert 6 is higher than the upper end of the first anchor bolt 11 and the second anchor bolt 13, the inner insert 6 is inserted into the inclined surface first. The inner plug 6 positions the inclined panel 2 within the plate 2. When the inclined panel 2 is tilted to the left or right or front or back, the inner plug 6 corrects the inclined panel 2, thereby correcting the steel beam 1. As the steel beam 1 slowly falls, the inner plug 6 is fully inserted into the inclined panel 2, thus completing the positioning installation. At this time, the first anchor bolt 11 passes through the four corners of the steel beam 1, and the first nut 10 is screwed on. Then, the auxiliary fixing frame 4 is placed in, and the second anchor bolt 13 passes through the auxiliary fixing frame 4. The second nut 12 is screwed on, and the fixing screw 3 is screwed into the end of the auxiliary fixing frame 4, between the inclined panel 2 and the inner plug 6, thus completing the installation.
