Description

Technical Field

[0001] The present application relates to a guide device and a structural component with the guide device, and is applicable to the technical field of construction equipment. Background Art

[0002] The post-insertion process of piles or anchors refers to inserting steel bars or steel cages into concrete, cement slurry, or mortar after pouring. At this time, it is usually necessary to set a guide device at the bottom of the steel bars or steel cages. The guide device preferably has a conical bottom. After the concrete bearing body hardens, the conical bottom and the concrete bearing body form a whole. This design enhances the integrity and stability of the structure, making the conical bottom widely used in use.

[0003] The Chinese patent application with publication number CN117328447A discloses a pressure-type post-insertion composite reinforcement anti-pullout pile for construction engineering, comprising an anti-pullout pile body, a composite reinforcement implanted inside the anti-pullout pile body, a composite reinforcement post-insertion cone head guide cap, a pressure plate, a lower positioning plate, a steel pipe bearing body, slow-bonding steel bars, a prestressed steel bar self-locking device and a prestressed steel bar, a post-insertion cone head guide cap inserted at the lower end of the anti-pullout pile body, and a cone surface of the cone head guide cap is a closed design. In addition, the side wall of the steel pipe bearing body arranged above the pressure plate is also a closed design. This closed conical bottom has the following problems: (1) it may make it difficult for the concrete slurry to penetrate evenly into all required areas during construction, especially at the contact point between the conical bottom and the steel bars, where the fluidity and filling capacity of the concrete are key. If the concrete cannot effectively fill these spaces, it may cause local voids and microcracks, affecting the overall structural integrity and bearing capacity. (2) The tensioning bars need to be in full contact with the concrete slurry to ensure the anchoring effect and force transfer. If the concrete cannot fully bond to the steel bars, it may cause loose anchoring, which in turn may lead to failure of the interface between the steel bars and concrete when tension is applied, affecting the overall performance of the pile. If the defects inside the conical space are later repaired or reinforced, this will greatly increase the construction and maintenance costs.

[0004] The Chinese patent application with publication number CN113152535A discloses a post-insertion unbonded steel strand pressure-bearing anti-pulling pile, comprising a concrete pile body, an unbonded steel strand and a precast concrete composite component; the unbonded steel strand and the precast concrete composite component are precast components, wherein the precast concrete composite component comprises a precast concrete cone, a guide device, a positioning device, an anchor plate and an anchor; the upper part of the precast concrete composite component is cylindrical or rectangular, and the lower part is conical. The lower positioning plate in the patent is arranged on the upper part of the conical guide device, and the defect of such arrangement is that the inner part of the conical guide device lacks support, which reduces the strength and rigidity of the conical guide device.

[0005] Therefore, there is a need in the prior art for a guiding device that can improve the technical problems existing in the closed conical bottom and enhance the strength of the conical bottom. Utility Model Content

[0006] The present application provides a guide device and a structural member having the guide device, which enables casting materials such as concrete to flow freely in the conical bottom and fill the entire area without causing local areas to be incompletely filled and form voids, thereby enhancing the use function of the structural member.

Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

[0021] The guide device of the present application includes a guide body 1, and an opening is provided on the guide body 1. A pressure plate 3 is provided on the top or inside of the guide body 1, and the guide body 1 and the pressure plate 3 are connected. The pressure plate 3 is provided with a rib hole for the tensioning bar 12 to pass through, and the bottom of the tensioning bar 12 is anchored on the pressure plate 3. The number of tensioning bars can be set as needed, for example, it can be one, two or three. In one embodiment, an extrusion sleeve 2 can be set between the pressure plate 3 and the bottom of the tensioning bar 12, and the tensioning bar passes through the extrusion sleeve 2 and is anchored on the pressure plate 3. As a part of the anchor, the extrusion sleeve 2 usually has a spring and tensioning bars inside. After the extrusion sleeve is inserted, the spring is broken after being squeezed, and the tensioning bar and the extrusion sleeve can be frictionally locked. At least one lower positioning plate 5 can also be provided in the guide body 1, and the lower positioning plate 5 and the pressure plate 3 are connected by a connecting rod 6, and the connecting rod 6 can be a screw. The lower positioning plate is arranged in the guide body to form a strength support for the guide body and improve the strength and stability of the structure. The extrusion sleeve 2 may be disposed between the lower positioning plate 5 and the pressure bearing plate 3. The guide body of the present application may preferably be in a cone shape, or may be in a prism or a prism shape.

[0022] like Figure 1 As shown, the guide body 1 is a conical body, which can be surrounded by a metal plate, and the opening 10 is arranged on the side wall of the metal plate. The opening 10 can be a rectangular opening, and its number can be set as needed, usually two symmetrically arranged. The tensioning reinforcement 12 can be a steel bar, a steel strand, a fiber reinforcement, etc. The conical body is preferably made of a steel plate, and the conical steel plate and the pressure plate can be welded and connected, for example, by a connection plate or a fillet weld. The lower positioning plate 5 is arranged above the bottom of the opening 10, so that the casting material can flow smoothly from the opening into the entire space of the conical body without generating a casting blind area. A through hole 11 can also be formed at the bottom of the guide body 1 so that a sealed air cavity will not be formed at the bottom of the cone during casting, resulting in unreal concrete casting.

[0023] like Figure 2 As shown, preferably, at least one upper positioning plate 4 can be spaced above the pressure plate 3 to position the tensioning bar 12. The pressure plate 3 is provided with a connection hole corresponding to the connecting rod 6.

Figure 4 As shown, the connection is first made to the joining component 9, and then the joining component 9 is connected to the pressure plate 3. The joining component 9 can be in the form of a connecting ring. Figure 4 The conical head shown in the figure does not affect the flow of concrete because there are openings between the steel bars. Figure 5 As shown, a pressure bearing member 7 may be provided on the pressure bearing plate 3. The pressure bearing member 7 may be in the form of a metal sleeve, and the pressure bearing member 7 is welded to the pressure bearing plate 3. Preferably, the pressure bearing member 7 is also provided with a side opening to facilitate the circulation of the casting material.

[0025] The present application provides an opening on the guide device so that the space inside the guide device is no longer closed, and the concrete can flow smoothly in the guide device and effectively fill the space inside the guide device, ensuring that the tensioning reinforcement can be effectively contacted and connected with the concrete, thereby ensuring the integrity and bearing capacity of the entire structure. Furthermore, the present application provides a lower positioning plate in the conical body so that a stiffening support can be formed in the conical body, thereby improving the overall strength of the conical body; at the same time, the lower positioning plate is provided above the bottom of the opening, which will not affect the flow of concrete in the conical body.
