Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a novel anti-detachment tension and compression support. Background Technology

[0002] Tension-compression bearings are key components used to connect the superstructure of a building structure (such as bridges and buildings) to the foundation. Their main functions are to transfer loads (including tension and compression), accommodate structural deformations (such as horizontal displacement and vertical rotation), and improve the safety, stability, and reliability of the structure.

[0003] However, during the grouting process of traditional tension-compression bearings, air retention can easily lead to incomplete grouting of the bearing base plate, resulting in voids. Voids cause uneven stress on the bearing, reducing the structural bearing capacity and potentially causing structural safety accidents in severe cases. Existing bearings also have insufficient displacement control, which can easily lead to excessive displacement and serious consequences such as beam collapse under the action of earthquakes and strong winds. The overall pull-out resistance of the bearings is also poor, failing to meet the structural stability requirements under some special working conditions. Therefore, a new type of anti-void tension-compression bearing is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a novel anti-void tension and compression bearing, which improves the problem in the existing technology where air retention during the grouting process of traditional bearings easily leads to incomplete grouting of the bearing base plate, resulting in voids. Voids will cause uneven stress on the bearing, reduce the structural bearing capacity, and in severe cases, may lead to structural safety accidents.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel anti-detachment tension and compression support, comprising an upper support plate, a lower support plate, an L-shaped hook, and a pier top anchoring assembly. A top plate is fixedly connected to the center of the top of the upper support plate, and wing plates are fixedly connected to both sides of the upper support plate. An upper threaded hole is provided on the upper surface of the upper support plate, and an upper structural plate is detachably installed on the surface of the upper threaded hole by means of an upper bolt. Limit grooves are provided on both sides of the wing plates. Longitudinal and transverse ribs are provided on the lower surface of the lower support plate, and baffles are fixedly connected to both sides of the upper surface of the lower support plate. Two sets of mounting holes A are provided on the surface of the baffles.

[0006] The pier top anchoring assembly includes a lower anchor bolt, the bottom end of which is threadedly connected to a lower sleeve, the bottom end of the outer wall of the lower sleeve is threadedly connected to a lower anchor rod, and the bottom end of the lower anchor rod is fixedly connected to an anti-pull-out structure.

[0013] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The fastening bolt is threaded into the inner wall of the mounting hole A.

[0017] As a further description of the above technical solution:

[0018] Both sides of the lower seat plate are provided with protrusions on their outer arc surfaces. The inner wall of the protrusions of the lower seat plate is provided with mounting holes B, through which the lower anchor bolts pass and contact the inner wall of the mounting holes B.

[0019] As a further description of the above technical solution:

[0020] The longitudinal and transverse ribs are all provided with inclined surfaces on all four sides.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting the inclined structure of longitudinal and transverse ribs, the problem of air retention in grouting is effectively solved, ensuring a tight connection between the support and the foundation and improving structural stability. At the same time, the shear-resistant structure and the pull-out-resistant structure enhance the support's ability to resist shear and tension, respectively, so that the support can still work stably under complex stress environment and improve the overall safety of the building structure.

In this utility model, the L-shaped hook design simplifies the processing technology, reduces costs, and has a reliable tensile structure that can effectively resist tensile forces, meet the stress requirements of different working conditions, and the wing plate limiting structure accurately controls the displacement of the support, ensuring structural safety under special working conditions and reducing the risk of accidents such as beam falling.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a novel anti-detachment tension-compression bearing, comprising an upper bearing plate 1, a lower bearing plate 2, an L-shaped hook 3, and a pier top anchoring assembly 4. A top plate 11 is fixedly connected to the center of the top of the upper bearing plate 1. The function of the top plate 11 is to enhance the shear resistance between the upper bearing plate 1 and the bridge superstructure, ensuring that the upper bearing plate 1 and the upper structural plate 7 can work together under horizontal loads. Wing plates 12 are fixedly connected to both sides of the upper bearing plate 1. Four sets of upper threaded holes 13 are opened on the upper surface of the upper bearing plate 1. The upper structural plate 7 is detachably installed on the surface of the upper threaded holes 13 by upper bolts 6. A slot is opened at the center of the upper structural plate 7. The inner wall contacts the outer wall of the top plate 11. The contact between the two allows for the positioning of the upper structural plate 7. The upper bolt 6 is threaded into the upper threaded hole 13 to fix the upper structural plate 7. The upper bolt 6 is threaded into the inner wall of the upper threaded hole 13. Limit grooves are provided on both sides of the wing plate 12. The upper surface of the lower seat plate 2 is fixedly connected to both sides of the upper surface of the lower seat plate 2. The inner side wall of the limit groove of the wing plate 12 and the outer wall of the stop strip 22 are connected with a certain gap. By providing limit grooves on both sides of the wing plate 12, the relative displacement of the upper seat plate 1 to the lower seat plate 2 is limited, preventing the support from moving beyond the limit and greatly reducing the risk of beam falling.

[0033] Reference Figures 2-4 The lower surface of the lower base plate 2 is provided with two sets of longitudinal and transverse ribs 21. The longitudinal and transverse ribs 21 are all provided with inclined surfaces on all four sides. By making the longitudinal and transverse ribs 21 all provided with inclined surfaces on all four sides, this inclined surface structure can guide air to be discharged smoothly during grouting operations, avoiding air from being retained between the support base plate and the lower structure, thereby ensuring the grouting chamber of the support base plate and preventing the occurrence of voids; the surface of the baffle 22 is provided with two sets of mounting holes A 221.

[0034] Reference Figure 3 The pier top anchoring component 4 includes a lower anchor bolt 41. Both sides of the lower seat plate 2 have protrusions on their outer arc surfaces. The inner wall of the protrusions of the lower seat plate 2 has an installation hole B 23. The lower anchor bolt 41 passes through and contacts the inner wall of the installation hole B 23. The bottom end of the lower anchor bolt 41 is threadedly connected to a lower sleeve 42. The bottom end of the outer wall of the lower sleeve 42 is fixedly connected to a lower anchor rod 43. The bottom end of the lower anchor rod 43 is fixedly connected to an anti-pull-out structure 411. The bottom end of the anti-pull-out structure 411 can be threaded, protruded, or other structures that can increase the anchoring force, and can be adjusted according to the actual use conditions.

[0035] Reference Figures 2-3 and Figure 5The bottom end of the upper seat plate 1 contacts the spherical crown plate 5, and the top end of the lower seat plate 2 contacts the lower surface of the spherical crown plate 5. By setting the spherical crown plate 5, it can achieve horizontal displacement function in cooperation with the upper seat plate 1 and vertical rotation function in cooperation with the lower seat plate 2. The surface of the L-shaped hook 3 is provided with a mounting hole C 32. The inner wall of the mounting hole C 32 is penetrated and contacts the fastening bolt 31. The fastening bolt 31 is threaded to the inner wall of the mounting hole A 221. The threaded connection between the two allows the L-shaped hook 3 to transfer the tension to the lower seat plate 2 when the support is subjected to tension, thus achieving the tensile function. Moreover, the design of the L-shaped hook 3 greatly reduces the processing difficulty of the tension and compression support compared with the traditional tensile structure.

[0036] Working principle: When installing the new type of anti-detachment tension and compression bearing, firstly, the lower anchor bolt 41 passes through the mounting hole B 23 on the protrusion of the lower seat plate 2 and cooperates with the lower sleeve 42, the lower anchor rod 43 and the anti-pull-out structure 411 to anchor the lower seat plate 2 to the top of the pier; then, the spherical crown plate 5 is placed so that it contacts the top of the lower seat plate 2; then, the upper seat plate 1 is placed on the spherical crown plate 5 so that the limiting grooves on both sides of the wing plate 12 cooperate with the stop strip 22 of the lower seat plate 2. The top plate 11 is positioned by the central slot hole of the upper structural plate 7. The upper structural plate 7 is connected and fixed to the upper seat plate 1 by the upper bolt 6. Finally, the L-shaped hook 3 is connected to the lower seat plate 2 by the fastening bolt 31. During use, the upper seat plate 1 bears and transmits the vertical load of the upper structure, while the wing plate 12 and the baffle 22 restrict horizontal displacement. The spherical crown plate 5 works with the upper seat plate 1 and the lower seat plate 2 to achieve horizontal displacement and vertical rotation, respectively. The L-shaped hook 3 transmits tension when under tension. The inclined surface design of the longitudinal and transverse ribs 21 on the lower surface of the lower seat plate 2 ensures that the grouting is dense and prevents voids. All components work together to ensure the stable operation of the support.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
