Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit support structures, in particular to a beam-column bracket structure, specifically an impact-resistant bracket, a use method, and an impact-resistant fish-belly beam support structure. Background Art

[0002] In the foundation pit support structure, fish belly beams are sometimes used in combination with columns in the foundation pit to laterally support the foundation pit wall, that is, the fish belly beams are placed horizontally to resist the horizontal force of the foundation pit. Under normal use, the fish belly beam is mainly used to resist the horizontal lateral pressure of the soil, but it is easy to become unstable when subjected to impact. In addition, in the foundation pit support structure, there are usually vehicle transportation operations around the fish belly beam, and the fish belly beam itself has prestressed stress, which makes it easy to become unstable out of plane when impacted, which will cause serious safety hazards to the fish belly beam and even the entire foundation pit support structure. The existing traditional fish belly beam supports do not take into account the impact damage effect and are difficult to resist impact damage, especially accidental impact in the vertical direction. Therefore, the present invention designs a new type of impact-resistant support to meet the needs of structural use. Summary of the Invention

[0008] In some embodiments, bolt holes are provided on the first surface of the bracket box body for being fixed to the column member of the support structure by bolt connection.

[0009] In some embodiments, k rows of bolt holes are symmetrically opened on the third and fourth surfaces of the bracket box, k>1, and the m rows of support members are fixed in the inner cavity of the box via bolt connections.

[0012] In some embodiments, the second surface of the bracket box is provided with a cover plate for closing and opening the inner cavity of the box.

[0013] In some embodiments, the bracket sliding member is a box-shaped short column, one end of the box-shaped short column extends into the inner cavity of the box body, and the other end of the box-shaped short column is used to support the beam component of the support structure.

[0014] In some embodiments, the engaging members are claws extending outward and downward on two opposite sides of the bracket sliding member in the second direction, the bottom surfaces of the claws are horizontal, and the top surfaces are inclined downward.

[0017] (3) Beneficial effects

[0018] The present invention designs a new impact-resistant bracket.

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in conjunction with the embodiments and drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0034] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] It should be understood that the terms "comprises / comprising," "consisting of," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product, apparatus, process, or method that includes a list of elements includes not only those elements but also, if necessary, other elements not explicitly listed, or elements inherent to such product, apparatus, process, or method. In the absence of further limitations, elements defined by the phrases "comprises / comprising," "consisting of," do not preclude the presence of additional identical elements in the product, apparatus, process, or method that includes the elements.

[0036] It should also be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific direction, be constructed or operate in a specific direction, and should not be understood as limiting the present invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0038] In the foundation pit support structure, when using a fish belly beam, the fish belly beam is placed horizontally to resist the horizontal force of the foundation pit. Under normal use, the fish belly beam is mainly used to resist the horizontal side pressure of the soil. There are often vehicle transportation operations around the fish belly beam. In addition, the fish belly beam itself has prestressing and is prone to out-of-plane instability when impacted. Therefore, the impact protection of the fish belly beam is crucial. The traditional fish belly beam support member cannot absorb the impact energy when the fish belly beam is impacted by falling objects or other impacts, and cannot provide effective impact protection, resulting in a safety hazard for the overall structure. Therefore, the present invention designs a new type of impact-resistant support. When the fish belly beam is impacted by falling objects or other impacts, the new type of impact-resistant support member will absorb the impact energy transmitted thereto by destroying the impact-resistant rib structure in the support member to protect the overall structure.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] See also Figure 1-3 An impact-resistant bracket 100 mainly includes a bracket box body 1 and a bracket slide 2. The bracket slide 2 is nested in the bracket box body 1 and can slide downward in the bracket box body 1 under certain conditions to absorb impact energy.

[0041] Specifically, such as Figure 1-3 As shown, the support box 1 has a first surface A1 and a second surface A2 that are opposite to each other in the first direction, and a third surface A3 and a fourth surface A4 that are opposite to each other in the second direction. The first surface A1, the second surface A2, the third surface A3 and the fourth surface A4 enclose the inner cavity 11 of the box. In this embodiment, the first surface A1 can be understood as the back side, or the rear side, of the support box 1, which is used for fitting the column installation. The second surface A2 can be understood as the front side, or the front side, of the support box 1. The third surface A3 and the fourth surface A4 are the left and right sides of the support box 1. It should be noted that although the support box 1 is described above as having a first surface A1, a second surface A2, a third surface A3 and a fourth surface A4, the support box 1 of the present invention cannot be strictly limited to being understood as a square structure. The present invention is demonstrated and explained using a square or a nearly square structure as an example, but it is obvious that this is not the only shape structure. The support box 1 of the present invention is preferably a cylindrical structure with a quadrilateral cross section, that is, similar to a short section of a steel pipe column.

[0042] See also Figure 3-4 On the third surface A3 and the fourth surface A4, m rows of support members 12 are symmetrically installed in the inner cavity 11 of the box, where m>1, that is, multiple rows of support members 12 are installed. The function of the support members 12 will be explained later.

[0043] Continue to see Figure 1-4 Specifically, the bracket sliding member 2 at least partially extends into the inner cavity 11 of the box body, and the bracket sliding member 2 is provided with n rows of clips 21 on the two opposite sides in the second direction, that is, n rows of clips 21 are provided on the two sides corresponding to the third surface A3 and the fourth surface A4 of the bracket box body 1, and the clips 21 on the opposite sides are respectively engaged with the support members 12 on the third surface A3 and the fourth surface A4; n≥1 and n<m, that is, the number of rows of clips 21 is less than the number of rows of support members 12, so that the support members 12 can support the clips 21 while there are surplus support members 12 for the clips 21 to slide and engage.

[0044] When the impact-resistant bracket of the present invention is in use, the bracket housing 1 is connected and fixed to the column component of the support structure, such as the column in the foundation pit support structure, through the first surface A1. The lower end of the bracket slide 2 is inserted into the inner cavity 11 of the bracket housing 1. The clamping member 21 on the bracket slide 2 is clamped and matched with the support member 12 in the bracket housing 1. The upper end of the bracket slide 2 is used to support the beam component of the support structure, such as the fish belly beam in the foundation pit support structure. When the fish belly beam is impacted, the bracket slide 2 tends to move downward, and the clamping member 21 on it impacts the support member 12, causing the support member 12 currently supporting the clamping member 21 to be damaged. While the support member 12 is damaged, the clamping member 21 continues to slide downward. Since the support member 12 is redundant relative to the clamping member 21, the clamping member 21 is clamped on the next row of support members 12 during the downward sliding process, forming a stable support again. In this process, the impact energy is absorbed to prevent the column from becoming unstable and the fish belly beam from being damaged by the impact. It should be noted that the upper end of the support slide 2 can directly support the fish belly beam, or can indirectly support the fish belly beam through a support beam. The upper end of the support slide 2 can be designed with an outward flange structure, with bolt holes or a flange plate provided on the flange structure to facilitate bolt connection and fixation with the drag beam.

[0045] In some embodiments, see Figure 1 First, on one hand, the first surface A1 of the bracket housing 1 is provided with bolt holes 13 for fixing to the column member of the support structure by bolt connection. The bolt holes 13 are provided in multiple rows according to the length and width of the bracket housing 1. Figure 1 As shown in the figure, 8 rows are opened vertically and 2 columns are opened horizontally to ensure that they can be stably connected to the columns. The bolt connection method is convenient for quick connection with the columns and can be disassembled and reused after use.

[0046] In some embodiments, the support members 12 are installed as follows: k rows of bolt holes 13 are symmetrically defined on the third and fourth surfaces A3 and A4 of the bracket housing 1, where k > 1. The m rows of support members 12 are bolted together and secured within the housing cavity 11. Providing bolt holes in the sidewalls of the bracket housing 1 and using bolts to install the support members 12 simplifies the structure and facilitates installation and removal. Furthermore, the number and location of the bolt holes can be flexibly adjusted according to actual needs, allowing for flexible installation of various rows of support members 12.

[0047] Preferably, the present invention sets k≥m, that is, the number of rows of bolt holes 13 on the third surface A3 and the fourth surface A4 is greater than or equal to the number of rows of support members 12 to be installed, so that the number and position of the support members 12 installed in the box cavity 11 can be adjusted, for example, each row is installed, or a number of rows are not installed, etc., so that a variety of different impact resistance conditions can be provided, such as Figure 5 .

[0048] The support member 12 provided by the present invention can be understood as an impact-resistant rib. In some embodiments, see Figure 4-5 The support member 12 is specifically an L-shaped steel plate. One side of the L-shape is provided with a bolt hole. This side is in contact with the third surface A3 and the fourth surface A4 and is bolted to the bolt holes 13 thereon. The other side of the L-shape supports the clip 21. The L-shaped steel plate is conveniently connected and fixed to the inner wall of the bracket housing 1 and also facilitates supporting the clip 21 on the bracket slider 2. The length of the L-shaped steel plate is consistent with the inner cavity 11 of the bracket housing 1. The length of each side and the thickness of the steel plate are determined based on the design requirements for impact resistance or engineering experience.

[0049] In some embodiments, see Figure 2 The second side A2 of the bracket housing 1 is provided with a cover 14 for closing and opening the housing cavity 11. The retractable design of the bracket housing 1 facilitates operations such as opening bolt holes in the housing cavity 11, installing the support member 12, and replacing the bracket slide 2. Furthermore, the cover 14 seals the internal structure, preventing contamination from the construction environment during long-term use and preventing internal snap-fit ​​and sliding failure. The cover 14 can be installed on the second side A2 of the bracket housing 1 using bolts.

[0050] In addition, a triangular support 3 is formed at the bottom of the bracket housing 1 to provide a reinforced support. The triangular support 3 can be formed by extending downward from the bottom of the bracket housing 1, or it can be an independent structure fixed to the bottom of the bracket housing 1.

[0051] On the other hand, in some embodiments, see Figure 4The bracket slide 2 is a box-shaped short column, one end of which extends into the box body cavity 11, and the other end of which is used to support the beam member of the support structure. The box-shaped short column structure is easy to nest with the bracket box 1, and the box structure can provide sufficient support strength and stability.

[0052] In some embodiments, see Figure 4 The clamping members 21 are arranged in three layers on both sides of the bracket sliding member 2 in the second direction, and are arranged at the bottom and middle position of the bracket sliding member 2, or are evenly spaced on the bracket sliding member 2.

[0053] More specifically, the clamping member 21 is a claw extending outward and downward on both sides of the bracket sliding member 2 relative to each other in the second direction. The claw is integrally formed with the bracket sliding member 2 to ensure that the claw is not easily damaged. The bottom surface of the claw is horizontal, and the top surface is tilted downward. The claw structure is convenient for clamping and cooperating with the L-shaped steel plate of the support member 12. The horizontal bottom surface is clamped on one side of the L-shaped steel plate, and the downward-tilted top surface provides sufficient vertical support strength. Under normal circumstances, it can ensure stable clamping and prevent the claw from being damaged before the L-shaped steel plate under the action of accidental impact, that is, to ensure that the claw remains effective and the L-shaped steel plate is damaged by impact. In this way, it is ensured that the clamping member 21 can be clamped again on the support member 12 of the next layer when sliding downward, clamping step by step, absorbing impact energy step by step, and not being completely destroyed.

[0054] On this basis, another aspect of the present invention provides a method for using an impact-resistant bracket, comprising:

[0055] S10, unscrew the bolts on the cover plate 14 and open the cover plate 14 of the bracket box 1;

[0056] S20, fixing m rows of L-shaped steel plates to the third surface A3 and the fourth surface A4 of the bracket box 1 via bolts in the box cavity 11 according to design requirements;

[0057] S30, fixing the first surface A1 of the bracket box 1 to the column member of the support structure via bolts;

[0058] S40, placing the bracket slide 2 into the box cavity 11, and making the claws engage with the L-shaped steel plate in place;

[0059] S50, installing the cover plate 14;

[0060] S60, connecting and fixing the beam member of the supporting structure to the top end of the bracket sliding member 2 via bolts.

[0061] like Figure 5 As shown, Figure 5(a), (b), and (c) in the figure respectively show three different impact strength settings from low to high. In (a), the L-shaped steel plates are sparsely spaced, and it can be seen that the L-shaped steel plates are not fully distributed. The top layer of clamps corresponds to one layer of L-shaped steel plates, the middle layer of clamps corresponds to two layers of L-shaped steel plates, and the bottom layer of clamps does not clamp the L-shaped steel plates for the time being. In this case, the impact strength is relatively low. In (b), the L-shaped steel plates are not fully distributed either. The three layers of clamps correspond to six layers of L-shaped steel plates, and each layer of clamps corresponds to two layers of L-shaped steel plates, but there is a gap between two adjacent layers of L-shaped steel plates. In this case, the impact strength is improved to a certain extent. In (c), the L-shaped steel plates are fully distributed. The three layers of clamps correspond to nine layers of L-shaped steel plates, and each layer of clamps corresponds to three layers of L-shaped steel plates, and there is no gap in the L-shaped steel plates. In this case, the impact strength is the highest. By properly disassembling and adjusting the position and number of the ribs (i.e., L-shaped steel plates) in the box cavity 11 by means of bolts, and by controlling the number and position of the ribs, various impact resistance conditions can be met.

[0062] like Figure 6 As shown, on this basis, the present invention also provides an impact-resistant fish belly beam support structure, which adopts the above-mentioned impact-resistant bracket 100 and includes:

[0063] Column 200;

[0064] The impact-resistant bracket 100 is installed on the side of the column 200;

[0065] The joist 300 is mounted on the impact-resistant bracket 100 and supported by the impact-resistant bracket 100;

[0066] The fish belly beam (not shown in the figure) is installed on the joist 300 and supported by the joist 300.

[0067] The column 200 is preferably an H-shaped steel column with bolt holes on the side of its flange to facilitate the installation of the impact-resistant bracket 100 by bolts. The support beam 300 is also an H-shaped steel beam with bolt holes on its lower flange, which is fixed to the top of the bracket sliding member 2 of the impact-resistant bracket 100 by bolts.

[0068] Although several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of the present invention. Certain features described in the context of separate embodiments may also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation may also be implemented in multiple implementations individually or in any suitable sub-combination.

[0069] While various embodiments of the present invention have been described above, the above descriptions are intended to be illustrative, non-exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable others skilled in the art to understand the embodiments disclosed herein.
