Description

Technical Field

[0001] This utility model belongs to the field of diaphragm walls, and in particular relates to a processing device for manufacturing heavy-duty small-diameter diaphragm wall steel cages. Background Technology

[0002] Diaphragm walls are constructed using trenching machinery to excavate a long, narrow trench along the perimeter of a deep excavation project, under slurry wall protection. After cleaning the trench, a reinforcing cage is lowered into the trench, and then underwater concrete is poured using the tremie method to form a unit segment. This process is repeated segment by segment to build a continuous reinforced concrete wall underground.

[0003] Currently, the commonly used supports or brackets in the production of steel cages can only process single-layer and lightweight steel cages, and cannot process small-diameter steel cages with a weight of more than 30t and a thickness between 800 and 1200mm.

[0004] For the diaphragm wall support structure of circular foundation pits, the commonly used methods can only make the foundation pit into a polygonal shape, and it is impossible to make it into a circle according to the design requirements. First, it cannot meet the design requirements, and second, after the foundation pit is excavated, the surface needs to be rounded, which wastes materials such as concrete, resulting in an increase in the process of making the rounded surface later, and the construction is more complicated.

[0005] This necessitates a new processing device capable of manufacturing large-scale, high-quality, and curved steel cages for underground continuous walls. Summary of the Invention

[0006] In view of this, the present invention aims to provide a processing device for manufacturing heavy-duty small-diameter underground continuous wall steel cages.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] A processing device for manufacturing heavy-duty small-diameter underground continuous wall steel cages includes several parallel horizontal beams and several parallel vertical beams. The horizontal beams and vertical beams are fixed perpendicularly to each other to form a grid-like base. The vertical beams are located below the horizontal beams. Above each horizontal beam, a row of columns is fixed. The upper ends of each row of columns are distributed in an arc shape. The upper end of each row of columns is fixed to an arc-shaped bracket.

[0009] Furthermore, in each row of columns, the columns at both ends are the tallest, while the columns in the middle are [height missing].

[0010] Furthermore, it also includes several longitudinal reinforcing ribs, each of which is located at the same position as several of the aforementioned arc-shaped brackets. Connecting several arc-shaped brackets together can effectively prevent deformation and increase strength.

[0011] Furthermore, it also includes several brackets, which are V-shaped structures located at the bottom of the longitudinal beams to support them. The grid-like base can be leveled by adjusting the brackets.

[0012] Furthermore, a transverse connecting bar is fixed above the beam, and the lower end of the column is fixed to the beam by means of fixing it to the transverse connecting bar.

[0013] Furthermore, several longitudinal connecting bars are provided between two adjacent longitudinal beams.

[0014] Furthermore, it also includes ground anchor bolts, which are used to fix the bracket to the foundation.

[0015] Furthermore, the various structures are fixedly connected by welding.

[0016] Furthermore, the arc-shaped bracket uses Φ22 or Φ25 HPB400 steel bars; the column, longitudinal connecting bar, and support use Φ28 HPB400 steel bars; the transverse connecting bar uses Φ25 HPB400 steel bars; the crossbeam and longitudinal beam use 14b# channel steel; and the ground anchor bolts are M28.

[0017] Furthermore, the interval between adjacent horizontal beams is 2000mm; the interval between adjacent longitudinal beams is 2000mm; the interval between adjacent longitudinal connecting bars is 600mm; the interval between adjacent columns in the same row is 200mm; and the height of the column at the outermost edge is 900mm.

[0018] The advantages and positive effects of this utility model are as follows: This solution can realize the fabrication of small-diameter irregular-shaped steel cages for the support structure of underground continuous walls in small-diameter circular foundation pits. It can quickly and conveniently process heavy-duty small-diameter steel cages. Currently, there is no equipment on the market that can process heavy-duty steel cages with curvature. This device realizes the rapid processing of ultra-heavy-duty small-diameter underground continuous wall steel cages, providing convenience for construction personnel, improving production efficiency, and ensuring project quality.

[0019] Furthermore, it has a simple structure and is easy and quick to install. It can be used to process and manufacture underground continuous wall steel cages with a weight of over 30t and a thickness of 800-1200mm and different curvatures, achieving the goal of rapid and accurate processing of steel cages, accelerating the overall progress of the project and improving work efficiency.

[0027] 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 scope of protection of the present utility model. In the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the structure of the device will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and height should be included.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 3 As shown, this utility model includes several parallel horizontal beams 5 and several parallel vertical beams 6. The horizontal beams 5 and vertical beams 6 are made of 14b# channel steel and are fixed perpendicularly to each other to form a grid-like base. The vertical beams 6 are located below the horizontal beams 5, and several V-shaped supports 7 are also provided at the bottom of the vertical beams 6. The supports 7 are fixed to the foundation by ground anchor bolts 8. The grid-like base can be leveled by adjusting the supports.

[0033] If the base is not level enough or the base is not flat enough, it can be leveled using a level instrument, and the height of bracket 7 can be adjusted to keep the overall structure level.

[0034] The required arc of the reinforcing cage is calculated by computer, thereby determining the height of each column. This ensures that the upper ends of the row of columns 2 fixed above each beam 5 form an arc shape. In each row of columns 2, the columns at both ends are the tallest, while the columns in the middle are 0cm high. The upper end of each row of columns 2 is fixed to an arc-shaped bracket 1, which is made of highly ductile round steel. The brackets are gradually fixed from one end of the row of columns to the other, forming an arc and completing the arc shaping of the bracket. This structure primarily controls the arc of the bracket by controlling the height of the columns.

[0035] It also includes several longitudinal reinforcing ribs, each of which is fixed at the same position to several of the aforementioned arc-shaped brackets 1. Connecting several arc-shaped brackets 1 together can effectively prevent deformation and increase strength.

[0036] A transverse connecting rib 4 is fixed above the crossbeam 5, and several longitudinal connecting ribs 3 are also provided between two adjacent longitudinal beams 6. The longitudinal and transverse connecting ribs connect the rows of arc-shaped brackets, so that the base is connected into a whole in both longitudinal and transverse directions, increasing the overall rigidity.

[0037] Various structures are fixedly connected by welding, a method that is safe and reliable.

[0038] The materials used in this plan are:

[0039] The arc-shaped bracket uses Φ22 or Φ25 HPB400 steel bars; the column, longitudinal connecting bar, and support use Φ28 HPB400 steel bars; the transverse connecting bar uses Φ25 HPB400 steel bars; the crossbeam and longitudinal beam use 14b# channel steel; and the ground anchor bolts are M28.

[0040] The relevant dimensions are:

[0041] The spacing between adjacent horizontal beams is 2000mm; the spacing between adjacent longitudinal beams is 2000mm; the spacing between adjacent longitudinal connecting bars 3 is 600mm; the spacing between adjacent columns 2 in the same row is 200mm; the height of the column at the outermost edge is 900mm. The length of the longitudinal beams is the same as the desired length of the steel cage.

[0042] When in use, we can build a steel cage above the arc-shaped bracket of this device according to the specified arc.

[0043] The existing cast-in-place pile reinforcement cage brackets (such as patent publication number CN101245595A) can only process round single-row reinforcement cages, and can only support light-weight reinforcement cages, so they can only process relatively short reinforcement cages. If a long reinforcement cage is needed, it needs to be made in sections and then spliced ​​together to form a long reinforcement cage. The splicing time is long, the construction efficiency is low, and the construction accuracy requirements are very high.

[0044] This device can process steel cages with a transverse width of 4-6m, a thickness of 800-1200mm, and a length of up to 50m. It can also directly process the upper and lower rows of steel mesh. The steel cage is integrally formed on this device in one piece, with good overall rigidity. The processed steel cage can bear a weight of over 30 tons, which is 10 to 20 times the load-bearing capacity of the cast-in-place pile steel cage bracket and 4 times the length of the cage processed in one piece. It eliminates the need for secondary or multiple splicing, improving construction efficiency and reducing construction difficulty. Furthermore, the materials used are the same as those used for diaphragm wall steel cages, eliminating the need for separate purchases or external processing, and greatly saving costs through on-site fabrication.

[0045] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
