Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway bridge construction, in particular to a prestressed deep-buried anchor rapid removal device. Background Art
[0002] Highway bridges are an important part of transportation facilities. Highway bridge cap beams and box beams require prestressed construction. During the construction process, deep-buried anchors are installed. The deep-buried anchors are designed with reserved tensioning openings. Therefore, when pouring concrete, holes are reserved as tensioning openings by deeply burying steel sleeves. Since the steel sleeves are integral structures and have no supporting parts inside, the thickness is generally more than 5mm to ensure load capacity. After the concrete is poured, they are difficult to remove, resulting in low construction efficiency. Some of the steel sleeves cannot be removed and can only be buried deep in the concrete. Moreover, the removed steel sleeves are severely damaged after cutting and knocking, and cannot be recycled again, resulting in a large amount of material waste. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the Invention
[0003] In view of the above-mentioned deficiencies, the purpose of the present invention is to provide a prestressed deep-buried anchor rapid removal device, which is provided with a tube support to enhance the load capacity of the embedded sleeve, making removal quick and convenient, thereby improving construction efficiency.
[0004] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is:
[0005] A prestressed deep-buried anchor rapid removal device, characterized by comprising:
[0006] The embedded sleeve with the embedded cavity includes a plurality of cylinder plates, two adjacent cylinder plates are connected to each other, and the thickness of the cylinder plates is 0.2 mm to 2 mm;
[0007] at least one inner support member disposed in the embedded cavity, for supporting the anchor;
[0008] A plurality of cylinder support members are arranged on the inner support member and are used to support the cylinder plate. One end of the cylinder support member abuts against the inner wall of the cylinder plate, and the other end thereof is connected to the inner support member.
[0009] As a preferred technical solution, the inner support member is an annular support ring.
[0010] As a preferred technical solution, the inner support member is a spiral support.
[0011] As a preferred technical solution, the cylindrical plates have a curved surface, and two adjacent cylindrical plates are overlapped and fixed to each other.
[0012] As a preferred technical solution, the cylindrical plates are in the shape of circular arcs and are arranged in a circular array.
[0013] As an optimal technical solution, the cylinder support member includes a fastening nut and a fastening support bolt. The fastening support bolt is arranged radially and is fixedly arranged on the inner support member. The fastening support bolt has a nut at one end that abuts against the inner wall of the cylinder plate, and the other end is threadedly connected to the fastening nut.
[0014] As a preferred technical solution, the number of the support rings is at least 2, and the support rings are concentrically arranged and spaced apart in the axial direction.
[0015] As a preferred technical solution, the support ring is fixedly provided with connecting ribs extending in the axial direction.
[0016] As a preferred technical solution, the material of the cylinder plate is a thin steel plate or a thin iron plate.
[0017] Compared with the traditional technical solution, the beneficial effects of the utility model are:
[0018] 1) The cylinder plates are connected to form embedded sleeves. Since the cylinder plates are thin, they are easily deformed by knocking and can be removed from the concrete more easily. In addition, there are multiple cylinder plates, which makes it easier to separate them from the concrete during removal. The cylinder supports can support the cylinder plates and improve the load capacity of the entire embedded sleeve. After the concrete is poured, the embedded sleeve will not be deformed. After the concrete is poured, the cylinder supports are removed, and then the cylinder plates are removed. The removal is quick and convenient, and the construction efficiency is high.
[0019] 2) The annular support ring has a simple structure and light weight. The anchor can pass through the support ring, which provides good support for the anchor and can serve as a fixing point for the tube support.
[0020] 3) The support ring has a disadvantage. Generally, multiple support rings are required. When dismantling, multiple support rings fall off, and the recovery amount is large. However, the spiral support generally only requires one, which extends along the axial direction. This can better support the anchor. At the same time, when dismantling, the whole can be directly recovered and recycled, saving material costs and making the operation more convenient.
[0021] 4) The purpose of the curved surface of the cylinder plate is to make the shape of the cavity close to a circle, preferably an arc shape, so that the reserved holes are more in line with the design requirements;
[0022] 5) The fastening support bolts and fastening nuts can be adjusted to adjust the support for the tube plate to ensure that the reserved sleeve will not be excessively deformed when bearing the concrete load. After pouring is completed, the fastening support bolts are easy to disassemble, and then it is more convenient to remove the tube plate;
[0023] 6) The connecting ribs connect the support rings into a whole, making installation and removal and recycling more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "top", "bottom", "left", "right", "front", "back", "inside", "outside" and the like appear to indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, they are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0028] Please refer to Figure 1 , an embodiment of the present invention provides a prestressed deep-buried anchor rapid removal device, comprising an embedded sleeve 1 with a embedded cavity 102, at least one inner support member 2 arranged in the embedded cavity 102 and a plurality of tube supports 3 arranged in the inner support member 2, the embedded sleeve 1 comprises a plurality of tube plates 101, two adjacent tube plates 101 are connected to each other, the thickness of the tube plates 101 is 0.2mm-2mm, the inner support member 2 is used to support the anchor, the tube support member 3 is used to support the tube plate 101, one end of the tube support member 3 is against the inner wall of the tube plate 101, and the other end is connected to the inner support member 2, first make a plurality of tube plates 101 , and then the cylinder plate 101 is connected to the embedded sleeve 1. Since the cylinder plate 101 is thin, it is easy to be knocked and deformed. In this way, the cylinder plate 101 is easier to fall off from the concrete and can be more easily removed from the concrete. There are multiple cylinder plates 101, which makes it easier to separate from the concrete during removal. The cylinder support 3 can support the cylinder plate 101 and improve the load capacity of the entire embedded sleeve 1. After the concrete pouring is completed, the embedded sleeve 1 will not be deformed. After the concrete pouring is completed, the cylinder support 3 is removed, and then the cylinder plate 101 is removed. The removal is quick and convenient, the construction efficiency is high, the labor intensity is low, and the removed cylinder plate 101 can generally be reused after a little processing, saving material costs.
[0029] like Figure 1As shown, the inner support member 2 is an annular support ring. The annular support ring has a simple structure and is lightweight. The anchor can pass through the support ring, which provides good support for the anchor and can serve as a fixed point for the tube support member 3. Specifically, the number of the support rings is at least 2, and the support rings are concentrically arranged and spaced apart in the axial direction. The more support rings there are, the better the support effect on the anchor, and they also play a guiding role.
[0030] like Figure 1 As shown, the inner support member 2 is a spiral spiral support. The spaced arrangement of the support rings has a disadvantage, and generally multiple support rings are required. During dismantling, multiple support rings fall off, and the recovery amount is large. However, generally only one spiral support is required, which extends axially, so that the anchor can be better supported. At the same time, during dismantling, the entire structure can be directly recovered and recycled, saving material costs and making operation more convenient.
[0031] like Figure 1 As shown, the cylinder plate 101 has a curved surface, and two adjacent cylinder plates 101 are overlapped and fixed to each other, that is, one end of one cylinder plate 101 is overlapped with the inner wall of one end of the other cylinder plate 101, so that the connection is more secure. Specifically, the shape of the cylinder plate 101 is an arc, and the cylinder plates 101 are arranged in a circular array. The cylinder plate 101 has a curved surface in order to make the shape of the cavity close to a circle. The cylinder plate 101 is preferably an arc, so that the reserved holes are more in line with the design requirements.
[0032] like Figure 1 As shown, the cylinder support 3 includes a fastening nut 301 and a fastening support bolt 302. The fastening support bolt 302 is arranged radially, and the fastening nut 301 is fixedly arranged on the inner support 2. The fastening support bolt 302 has a nut at one end that is against the inner wall of the cylinder plate 101, and the other end is threadedly connected to the fastening nut 301. The fastening support bolt 302 cooperates with the fastening nut 301 to be telescopically adjusted to adjust the support for the cylinder plate 101 and ensure that the reserved sleeve will not be excessively deformed when bearing the concrete load. After pouring is completed, the fastening support bolt 302 is easy to disassemble, and then it is more convenient to remove the cylinder plate 101.
[0033] like Figure 1 As shown, the support ring is fixedly provided with connecting ribs extending in the axial direction, and the connecting ribs connect the support ring into a whole, thereby improving the overall rigidity and making installation, removal and recycling more convenient.
[0034] like Figure 1 As shown, the material of the cylinder plate 101 is a thin steel plate or a thin iron plate, and the material cost is low.
