Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a footnote. Background Art

[0002] The column foot node of the frame column is the link to realize the internal force transmission between the superstructure and the base, and its performance and quality are very important for the entire project. The form of the column foot can be simply divided into two types according to its force transmission characteristics: hinged type and rigid type. The former only transmits axial force and shear force, while the latter can also transmit the bending moment from the column body. The rigid column foot can provide rigid constraints on the column body and reduce the lateral deformation of the column body under the action of axial force. In the current substation steel frame design, the rigid column foot has many advantages over the hinged column foot, so the hinged column foot has gradually withdrawn from the stage of history.

[0003] Traditional footers are usually fixed by the sleeve insertion method, where the sleeve is fixed on the ground, and then the steel pipe is inserted into the sleeve and fixed by bolts; however, this fixing method has the following defects: when the steel pipe is separated from the sleeve, since the top of the sleeve is open, external particles usually fall into the sleeve. When the steel pipe is inserted next time, the particles in the sleeve will block the steel pipe, making it impossible to insert the steel pipe downward, resulting in misalignment between the mounting holes on the steel pipe and the mounting holes on the sleeve. Therefore, the bolts cannot be installed. Utility Model Content

[0004] The utility model aims to solve the problem that the mounting hole on the steel pipe and the mounting hole on the sleeve are misaligned and the bolt cannot be installed.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a footer; comprising a base plate and a plurality of sleeves fixed on the base plate, and a support rod is inserted on the sleeve, a mounting cylinder and a threaded cylinder are fixed on the outer surface of the sleeve, and the axes of the mounting cylinder and the threaded cylinder are located on the same straight line, the same bolt is installed in the mounting cylinder and the threaded cylinder, a mounting hole for use with the bolt is opened on the sleeve, a spring is fixed on the inner bottom wall of the sleeve, and a sealing block for sealing the top opening of the sleeve is fixed on the top of the spring; when the support rod is not inserted into the interior of the sleeve, the thrust of the spring pushes the sealing block upward, and the opening at the top of the sleeve can be sealed by the sealing block.

[0006] Furthermore: a support ring is fixed to the lower part of the inner bottom wall of the sleeve, and the inner diameter of the support ring is smaller than the diameter of the sealing block. When the sealing block moves downward, the support ring supports the sealing block.

[0007] Furthermore: a limiting groove is provided on the inner side wall of the sleeve along the axial direction, a sliding block is fixed to the outer surface of the support rod, and the sliding block is installed inside the limiting groove so as to slide up and down.

[0008] Furthermore: the bottom end of the sleeve is fixedly connected to the top of the base plate through a fixing plate, a plurality of ribs are fixed on the outer surface of the sleeve at equal intervals along the circumferential direction, and a plurality of ribs are fixed on the top of the same fixing plate.

[0009] Furthermore: the thickness of the sealing block is greater than the aperture of the mounting tube.

[0010] Beneficial effects of the utility model:

[0011] The utility model provides a spring and a sealing block inside the sleeve. When the steel pipe is separated from the support rod, the spring can push the sealing block upward, so that the opening at the top of the sleeve and the mounting tube can be blocked by the sealing block to prevent foreign particles from falling into the sleeve, reduce the obstruction of the support rod by particles and cause the mounting hole and the mounting tube and the grooved tube to be misaligned, thereby facilitating the installation of the bolt.

[0012] The utility model has a limiting groove on the inner side wall of the sleeve and a sliding block fixed on the outer surface of the support rod. When the support rod is installed, the limiting groove and the sliding block cooperate to limit the support rod, so that after the support rod is inserted into the interior of the sleeve, the mounting hole is directly aligned with the mounting tube and the threaded tube, and there is no need to rotate and adjust the support rod, which brings convenience to the staff.

[0018] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0019] Embodiments of the present utility model:

[0020] like Figure 1 and 2 As shown: a footer includes a base plate 1, a plurality of fixed plates 13 are equidistantly fixed on the top of the base plate 1, a sleeve 2 is fixed on each fixed plate 13, and a plurality of ribs 14 are equidistantly fixed on the outer surface of the lower part of the sleeve 2 along the circumferential direction, and a plurality of ribs 14 are fixedly connected to the top of the same fixed plate 13. The arrangement of the ribs 14 reinforces the sleeve 2, thereby reducing the phenomenon of tilting or breaking of the sleeve 2 during use.

[0021] like Figure 2 As shown: the inside of the sleeve 2 is inserted with a support rod 3. It should be noted that: the support rod 3 is a steel pipe, and the outer surface of the base plate 1 is fixed with a mounting tube 4 and a threaded tube 5, and the axes of the mounting tube 4 and the threaded tube 5 are located on the same straight line. A mounting hole 7 is opened at the lower part of the support rod 3, and after the support rod 3 is inserted into the inside of the mounting hole 7, the bolt 6 passes through the mounting tube 4, the mounting hole 7 and the threaded tube 5 in sequence for threaded connection, thereby playing a role in fixing the support rod 3 and reducing the shaking or movement of the support rod 3 in the sleeve 2.

[0022] like Figure 2 As shown: the inner wall of the sleeve 2 is symmetrically provided with a limiting groove 11 about the axis, and the outer surface of the support rod 3 is symmetrically fixed with a slider 12 about the axis, and the slider 12 is slidably installed in the limiting groove 11. Through the setting of the limiting groove 11 and the slider 12, the support rod 3 is limited, so that the mounting hole 7 on the support rod 3 can be directly aligned with the mounting tube 4 and the threaded tube 5, and there is no need to rotate and adjust the support rod 3, thereby providing convenience for the staff.

[0023] like Figure 3As shown: a spring 8 is fixed to the inner bottom wall of the sleeve 2, and a sealing block 9 is fixed to the top of the spring 8. It should be noted that the thickness of the sealing block 9 is greater than the diameter of the mounting tube 4. The sealing block 9 is slidably installed inside the sleeve 2. When the support rod 3 is taken out from the inside of the sleeve 2, the spring 8 loses the extrusion force and pushes the sealing block 9 upward. The sealing block 9 can block the opening at the top of the sleeve 2. The outer surface of the sealing block 9 can block the mounting tube 4 to reduce the entry of particulate matter into the interior of the sleeve 2. A support ring 10 is fixed to the inner bottom wall of the sleeve 2. It should be noted that the aperture of the support ring 10 is smaller than the outer diameter of the sealing block 9. Through the setting of the sealing block 9, if the self-gravity of the support rod 3 squeezes the spring 8 downward, the support ring 10 plays a role in supporting the sealing block 9.

[0024] When installing the base plate 1, first fix the base plate 1 on the ground, and then insert the support rod 3 into the interior of the sleeve 2, so that the sliders 12 on both sides of the support rod 3 slide in the limit grooves 11, and the self-weight of the support rod 3 applies downward pressure to the sealing block 9. When the sealing block 9 is subjected to the applied pressure, the sealing block 9 moves downward and squeezes the spring 8. At this time, the spring 8 changes from the original state to the compressed state. If the bottom of the sealing block 9 conflicts with the top of the support ring 10, the mounting holes 7 on the support rod 3 are respectively aligned with the mounting tube 4 and the threaded tube 5, and then the bolts 6 are used to pass through the mounting tube 4 and the mounting holes 7 in turn and are threadedly connected to the threaded tube 5, thereby completing the work of fixing the support rod 3.

[0025] When removing the support rod 3, first remove the bolt 6 from the threaded tube 5, the mounting hole 7 and the mounting tube 4 in turn, and then the support rod 3 can be taken out from the inside of the sleeve 2. After the support rod 3 is taken out, the spring 8 loses the extrusion force, and the spring 8 recovers from the extrusion state to the original state and pushes the sealing block 9 upward. The sealing block 9 can block the opening of the sleeve 2 and the mounting hole 4, thereby reducing the entry of external impurities into the sleeve 2, resulting in the situation where particulate matter blocks the support rod 3 when the support rod 3 is installed next time.
