Description

Technical Field

[0001] The utility model relates to the technical field of steel cages, in particular to a steel cage structure of an ecological T-shaped pile. Background Art

[0002] T-shaped piles are an important component of river bank retaining walls at this stage and are widely used in river construction. They are mainly made of internal steel keels and concrete pouring. The existing T-shaped piles are whole-pile T-shaped structures, which leads to the internal steel keels also being whole-pile T-shaped structures. This structure will increase the amount of steel bars used, resulting in higher manufacturing costs and lower economic practicality. The whole-pile T-shaped structure also causes inconvenience for the later pre-embedding of the lower end of the pile body. To this end, in response to the above problems, a steel cage structure of an ecological T-shaped pile is designed to better meet actual use needs. Utility Model Content

[0003] The utility model aims to provide a steel cage structure of an ecological T-shaped pile to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel cage structure of an ecological T-shaped pile, including a web and a flange plate, the flange plate is fixed on the web, the web is composed of a stirrup body and main steel bars, the stirrup body and the main steel bars pass through the center of the flange plate, and the flange plate is composed of a combination of transverse bars and longitudinal bars.

[0005] Preferably, an end plate is installed on the upper end of the web, the end plate is a "T"-shaped structure, and the two lateral ends of the "T" are provided with S-shaped splicing joints, and the S-shaped splicing joints can facilitate the subsequent splicing and assembly of the pile body.

[0006] Preferably, the two ends of the transverse rib are bent into a "Z"-shaped structure. The "Z"-shaped structure at the two ends of the transverse rib can support the flange of the formed pile body, ensure the stability of the pile body flange, and facilitate the later assembly of the pile body.

[0007] Preferably, the transverse and longitudinal bars are crisscrossed to form a steel mesh, and the intersections of the transverse and longitudinal bars are fixed by wire binding or welding. The crisscrossed distribution of the transverse and longitudinal bars can ensure the bending and shear resistance of the later formed pile body.

[0008] Preferably, the stirrup body and the main steel bar are fixedly connected to form a rectangular main keel, and the rectangular main keel and the steel mesh are vertically distributed, and the width of the steel mesh is more than 1.5 times the width of the rectangular main keel. At the same time, the length of the steel mesh is less than the length of the rectangular main keel. By limiting the length and width of the rectangular main keel, the entire steel keel can be made into a semi-T-shaped structure, thereby effectively saving the amount of steel bars and reducing production costs.

[0009] Preferably, the stirrup body is a spiral stirrup or a square stirrup, and the main steel bar is an ordinary steel bar, a prestressed steel bar or a prestressed steel strand. The performance of the entire steel keel can be guaranteed through the action of the main steel bar and the stirrup body.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the steel cage structure of the ecological T-shaped pile is a semi-T-shaped structure composed of a rectangular main keel and a steel mesh. Compared with the traditional full T-shaped structure, it can greatly save materials while ensuring the performance of the pile body, reduce production costs, and improve cost performance. The rectangular main keel has a larger main reinforcement distance and a reasonable and effective main reinforcement arrangement structure, so that the rectangular main keel and the concrete form a smaller amount of steel bars after solidification to achieve greater mechanical properties, and the entire steel bar is firm.

[0011] The T-shaped steel cage is essentially a combination of a rectangular steel cage and a plate-type steel mesh, which greatly improves the performance with the same amount of steel bars, while avoiding many defects of the separate rectangular steel cage and plate-type steel mesh, such as the inability to form performance superposition, the easy separation of the component combination after casting and the inability to form a reliable and stable structure, and other problems.

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 without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 5 The utility model provides a technical solution: a steel cage structure of an ecological T-shaped pile, including a web 1 and a flange plate 2, the flange plate 2 is fixed on the web 1, the web 1 is composed of a stirrup body 6 and a main steel bar 7, the stirrup body 6 and the main steel bar 7 pass through the center of the flange plate 2, and the flange plate 2 is composed of a combination of transverse ribs 3 and longitudinal ribs 4.

[0020] An end plate 5 is installed at the upper end of the web 1, and the end plate 5 is a "T"-shaped structure, and the two transverse ends of the "T" are provided with S-shaped joints; the transverse ribs 3 and the longitudinal ribs 4 are crisscrossed to form a steel mesh, and the intersection of the transverse ribs 3 and the longitudinal ribs 4 is fixed by steel wire binding or welding; the stirrup body 6 and the main steel bar 7 are fixed to form a rectangular main keel, and the rectangular main keel and the steel mesh are vertically distributed, and the width of the steel mesh is greater than 1.5 times the width of the rectangular main keel, and the length of the steel mesh is less than the length of the rectangular main keel; the stirrup body 6 is a spiral stirrup or a square stirrup, and the main steel bar 7 is an ordinary steel bar, a prestressed steel bar or a prestressed steel strand;

[0021] When producing the reinforced cage structure of the ecological T-shaped pile, Figure 1 and Figure 2 As shown, a rectangular main keel can be formed by consolidating the stirrup body 6 and a plurality of main steel bars 7, and then the transverse bars 3 and the longitudinal bars 4 are staggered and fixed to form a steel mesh, and finally the steel mesh and the rectangular main keel are welded and assembled to form a semi-T-shaped steel cage, and the length and width of the rectangular main keel can be limited according to actual needs to meet actual use requirements, and compared with the traditional full T steel cage, the semi-T steel cage can greatly save the amount of steel while ensuring performance, and ensure cost performance;

[0022] The two ends of the transverse rib 3 are bent into a "Z"-shaped structure;

[0023] After the semi-T-shaped steel cage is produced, Figure 3As shown, the semi-T-shaped steel cage frame can be combined with concrete to form a semi-T-shaped pile body, and the side of the pile body has an arc structure for splicing, which, in conjunction with the "Z"-shaped structure at both ends of the transverse reinforcement 3, can support the side arc structure of the semi-T-shaped pile body to ensure stability. When the pile body is installed, the lower rectangular structure can be conveniently embedded in advance, thereby reducing the difficulty of installation. When the pile body is spliced, when only a single layer is required, such as Figure 4 As shown, the assembly function can be achieved by splicing the arc-shaped structures on the sides of adjacent flange plates 2. When double-layer assembly is required, as shown in FIG. Figure 5 As shown, a double-layer assembly effect can be achieved by splicing the arc-shaped edge structure of the upper flange plate 2 of the upper half T-shaped pile body with the arc-shaped edge structure of the upper web plate 1 of the lower half T-shaped pile body, so as to better meet actual use requirements.
