[0031] Compared with the prior art, the application has the beneficial effects that:

[0032] The application sets the reinforcing structure as a plurality of reinforcing plates, designs the reinforcing structure as a plurality of independent reinforcing plates, adopts a unitized design concept, provides a connecting piece between adjacent reinforcing plates, and forms a movable connection between the adjacent reinforcing plates and the connecting piece, so that the single foundation foundation can not affect the settlement of other foundation foundations when bearing load and settling, thereby avoiding adverse effects on the buildings on other foundation foundations, effectively solving the problem that uneven settlement is caused by different building loads when the traditional foundation foundations are connected into one piece, and finally causing the buildings to tilt. In addition, the application adds a transverse reinforcing beam and a longitudinal reinforcing beam at the bottom of the reinforcing plate, significantly enhances the structural strength of the reinforcing plate itself, makes it better cope with various complex stress conditions, and further improves the stability and reliability of the entire reinforcing structure.

[0033] The combination of the longitudinal and transverse reinforcing beams enables the reinforcing plate to better bear the load from the upper building, disperse stress, reduce the situation of excessive local stress, and provide more stable support for the foundation foundation. The reinforcing plate, the transverse reinforcing beam and the longitudinal reinforcing beam are buried in the foundation foundation, so that the stiffness of the bearing layer of the natural foundation is significantly improved. The increase of the stiffness of the bearing layer can better resist foundation settlement, especially in the case of uneven settlement, and reduce foundation deformation.

[0034] By setting the longitudinal reinforcing beam as an arch unit, the sliding direction of the reinforcing plate compared to the extension direction of the longitudinal reinforcing beam is reduced.

[0035] In the application, the adjacent reinforcing plates are connected by the connecting piece, and the connecting piece is movably connected with the connecting ring at the end of the transverse reinforcing beam, forming a movable settlement joint. This enables the foundation plate to be divided into independent stress units, and when a local area is subjected to a large load or settlement, it will not affect the foundation foundation of other areas; at the same time, the connecting ring can deform under stress, which can effectively reduce the influence of local stress on the overall structure, avoid damage to the entire foundation foundation caused by local problems, and further improve the stability and safety of the foundation foundation.

[0036] In the application, the connecting piece is composed of multiple connecting modules, the connecting modules are connected through threads, and installation is convenient and fast. The length and the connecting position of the connecting piece can be flexibly adjusted according to actual needs on the construction site, different sizes and shape requirements of different foundation bases are adapted, the clamping part of the second connecting part and the inner profile of the first connecting part are provided as corresponding tapered structures, the stability of the connection between the first connecting part and the second connecting part is realized, the tensioning groove is arranged on the clamping part of the second connecting part, the easy connection of the two is realized, and the connection loosening of the first connecting part and the second connecting part after connection is avoided.

[0037] The gap between the connecting ring at the end of the transverse reinforcing beam and the mounting part is arranged, so that the transverse reinforcing beam can have a certain movement space relative to the connecting piece during installation, the alignment and adjustment during installation are facilitated, the construction efficiency is improved, and the construction difficulty is reduced.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0045] As shown in the accompanying drawings, the application is an anti-settlement foundation reinforcing structure, which comprises reinforcing plates and connecting members; Figure 1

[0046] The connecting member 4 is located between two adjacent reinforcing plates (the first reinforcing plate 1 and the second reinforcing plate 7) and is arranged along the extension direction of the reinforcing plates; Figure 1

[0047] The bottom of the reinforcing plate is provided with a plurality of transverse reinforcing beams and a plurality of longitudinal reinforcing beams along the transverse and longitudinal directions respectively, and the area of the reinforcing plate is determined according to the superstructure; the area of the reinforcing plate is consistent with the cross section of the corresponding superstructure, so as to realize the accurate correspondence between the reinforcing plate and the superstructure, thereby ensuring that superstructures of different heights can be respectively arranged on the reinforcing plates matched therewith; by making the area of the reinforcing plate same as the cross section of the corresponding superstructure, the reinforcing plate and the superstructure are matched one by one, so that superstructures of different heights are arranged on the corresponding reinforcing plates respectively;

[0048] The longitudinal reinforcing beams are respectively arranged at intervals along the extension direction of the reinforcing plate, and the longitudinal reinforcing beams are respectively mounted on the bottom of the reinforcing plate;

[0049] The transverse reinforcing beams are respectively perpendicular to the longitudinal reinforcing beams (i.e. the transverse reinforcing beams are arranged along the transverse direction of the reinforcing plate), and the transverse reinforcing beams are respectively mounted on the bottom of the reinforcing plate and located at the outer side of the reinforcing plate at both ends respectively;

[0050] The opposite ends of the corresponding two transverse reinforcing beams (i.e. the first transverse reinforcing beam 2 on the first reinforcing plate 1 and the second transverse reinforcing beam 6 on the second reinforcing plate 7) on two adjacent reinforcing plates (the first reinforcing plate 1 and the second reinforcing plate 7) are respectively arranged staggered, the ends of the transverse reinforcing beams are respectively arranged in gaps with the connecting member 4, and the transverse reinforcing beams rotate along the connecting member 4.

[0051] Further, the connecting member comprises a plurality of connecting modules;

[0052] The connecting modules are sequentially connected head to tail to form the connecting member, as shown in the accompanying drawings; Figure 2 The connecting module comprises a first connecting part 41, a limiting part 42, a mounting part 43 and a second connecting part which are sequentially connected along the extension direction of the reinforcing plate;

[0053] The limiting part 42 is in a ring structure and is mounted between the first connecting part 41 and the mounting part 43;

[0054] The opposite ends of the corresponding two transverse reinforcing beams on two adjacent reinforcing plates are respectively mounted on the mounting part 43 and rotate around the connection with the mounting part respectively;​​

[0055] The cross-section of the first connecting part 41 and the cross-section of the limiting part 42 are larger than the cross-sections of the second connecting part and the mounting part 43, respectively. The inner contour of the first connecting part 41 matches the outer contour of the second connecting part. The first connecting part 41 is threadedly connected to the second connecting part on the adjacent connecting module (that is, in two adjacent connecting modules, the first connecting part 41 on one connecting module is threadedly connected to the second connecting part on the other connecting module that is close to the first connecting part 41).

[0056] Furthermore, the second connecting portion includes an external thread 44 and a clamping portion disposed along the extending direction of the connecting member;

[0057] The external thread 44 is located between the clamping part and the mounting part 43;

[0058] The clamping part is generally tapered, and the cross section of the clamping part decreases linearly along the direction away from the external thread. Several tension grooves 45 are evenly provided on the clamping part.

[0059] The tensioning groove 45 is provided along the extending direction of the clamping part, and the tensioning groove 45 extends through the inside and outside of the clamping part.

[0060] Furthermore, the inner side of the end of the first connecting part 41 facing away from the second connecting part on the same connecting module is provided with an internal thread that matches the external thread 44. The shape and size of the inner side of the end of the first connecting part 41 facing the second connecting part on the same connecting module are matched with the overall shape and size of the clamping part, that is, the shapes of the two are matched with each other. This structural design is beneficial to the tightness and stability of the connection.

[0061] Further details are attached. Figures 3-5 The longitudinal reinforcement beam 8 shown includes several arched units. The design of the arched units has unique advantages. Its arched structure can effectively distribute the pressure from above to the bottom of the reinforcement plate and the adjacent arched units. Compared with ordinary beam structures, it can better withstand the stress changes caused by uneven settlement of the foundation, improve the bending resistance of the reinforcement plate, and thus enhance the stability of the entire foundation, while avoiding lateral displacement of the reinforcement plate as a whole.

[0062] Several arched units are arranged along the transverse direction of the reinforcing plate, and the tops of the arched units are respectively connected to the...

[0063] The bottom of the reinforcing plate;

[0064] The transverse reinforcing beams are respectively located between two adjacent arch units, the top of the transverse reinforcing beam is connected with the bottom of the reinforcing plate, and the opposite sides of the transverse reinforcing beam are respectively connected with the opposite sides of the two adjacent arch units.

[0065] Further, the end of the transverse reinforcing beam is respectively provided with a connecting ring;

[0066] The connecting ring is respectively connected perpendicularly to the end of the transverse reinforcing beam, that is, the end face of the connecting ring is perpendicular to the extension direction of the transverse reinforcing beam, the connecting ring is respectively sleeved on the mounting portion, and is provided with a gap from the mounting portion.

[0067] Further, the inner profile size of the connecting ring is greater than the outer profile size of the mounting portion and is less than the outer profile size of the limiting portion and the first connecting portion.

[0068] Further, the connecting ring is in an elliptical shape.

[0069] Further, the overall thickness of the limiting portion and the thickness of the end of the first connecting portion 41 and the second connecting portion are greater than the thickness of the connecting ring.

[0070] It should be noted that:

[0071] In the present application, the length of the mounting portion 43 is determined according to the number of connecting rings mounted on the mounting portion 43 and the thickness of the unit connecting ring, that is, the length of the mounting portion 43 is equal to the product of the number of connecting rings and the thickness of the unit connecting ring.

[0072] In use, first, the reinforcing plates are respectively installed on the foundation, and the opposite ends of the transverse reinforcing beams of the two adjacent reinforcing plates are respectively staggered;

[0073] Then, the head and tail of each connecting module are placed between the two adjacent reinforcing plates along the extension direction of the reinforcing plate; the tail of the connecting module (that is, the second connecting portion) is first sequentially inserted through the connecting rings connected to the staggered ends of the transverse reinforcing beams of the two adjacent reinforcing plates (for example, the first connecting ring 3 connected to the first transverse reinforcing beam 2 and the second connecting ring 5 connected to the second transverse reinforcing beam 6), and then is threadedly connected with the corresponding first connecting portion 41 in the adjacent second connecting module. Such a connection mode can ensure that the adjacent reinforcing plates form a stable and movable connection structure through the connecting member, thereby adapting to the slight deformation of the foundation under different conditions; the installation of the entire connecting member between the two adjacent reinforcing plates and the connection of the opposite end of the transverse reinforcing beam on the two adjacent reinforcing plates to the connecting member are sequentially completed in this way.

[0074] Finally, each connecting module is fixed to the foundation by bolts to complete the fixation of the entire connecting member.

[0075] In use, due to the unitized design of the reinforcing structure (i.e. divided into several reinforcing plates), a single reinforcing plate is respectively installed on the foundation base located directly below the unit building, a transverse reinforcing beam and a longitudinal reinforcing beam are respectively arranged at the bottom of the reinforcing plate to improve the strength of the reinforcing plate itself, thereby improving the overall strength of the foundation plate, the reinforcing plate, the transverse reinforcing beam and the longitudinal reinforcing beam located at the bottom of the reinforcing plate are respectively buried in the foundation base, so that the bearing layer of the natural foundation has greater rigidity, thereby further improving the anti-settlement property of the foundation base;

[0076] A connecting piece is arranged between the two adjacent reinforcing plates, and the two adjacent reinforcing plates are movably connected with the connecting piece through the connecting ring at the end of the cross beam, so that a movable settlement joint is formed between the two adjacent reinforcing plates, thereby dividing the entire foundation base into independent force receiving units. When the foundation base is locally stressed, due to the gap between the connecting ring and the mounting portion and the elliptical shape, the connecting ring can deform to a certain extent. This deformation can buffer and disperse the local stress, avoiding the direct transmission of the local stress to the overall structure, thereby effectively reducing the impact of the local stress on the entire foundation base and further improving the stability of the foundation base under complex stress conditions.
