Description

Technical Field

[0001] The utility model relates to the technical field of anchorages, in particular to an anchorage that can be unlocked and recycled. Background Art

[0002] Anchors play a key role in concrete structures. The anchor head structure, when combined with the anchor rod, can tighten the anchor rod, increase the prestress of the concrete structure, enhance the bearing capacity of the structure, and ensure the stability and safety of the structure.

[0003] The existing prestressed concrete anchor rods rely on the locking tension of the anchor head nut. When the nut loosens under the action of external forces such as vibration, the tensioning effect of the anchor rod on the concrete structure is reduced, affecting the stability of the concrete structure. Therefore, an unlockable and recyclable anchor is proposed to provide a set of recyclable unlocking anchor structure with good tensioning and locking effect for the construction of prestressed concrete, so that the anchor rod has a double locking effect and can be recycled, thereby reducing the loss of the anchor head structure and reducing the cost of prestressed concrete construction. Utility Model Content

[0004] In response to the problems in the prior art, the utility model provides an unlockable and recyclable anchor to provide a set of recyclable unlocking anchor structure with good tensioning and locking effect for the construction of prestressed concrete, so that the anchor rod has a double locking effect and can be recycled, thereby reducing the loss of the anchor head structure and reducing the cost of prestressed concrete construction.

[0005] The technical solution adopted by the utility model to solve the technical problem is an anchor that can be unlocked and recycled, including:

[0006] Anchor plates;

[0007] Anchor head structures, at least one set is provided and arranged on the anchor plate;

[0008] At least one group of anchor rods is provided and connected to the anchor head structure.

[0009] By adopting the above technical scheme, a set of recyclable unlocking anchor structure is provided for the construction of prestressed concrete through the components consisting of anchor plates, anchor head structures and anchor rods. The anchor head structure used for tensioning on the anchor rod can be removed for later recycling without cutting the anchor rod and destroying the anchor head structure, thereby reducing the loss of the anchor head structure. The anchor head structure can be well recycled when needed, effectively reducing the cost of prestressed concrete construction.

[0010] Specifically, the anchor head structure includes:

[0011] An external threaded sleeve is inserted into the anchor plate;

[0012] The conical insert cavity is arranged at the center of the external thread sleeve;

[0013] A conical insert sleeve is inserted into the conical insert cavity;

[0014] A first nut connected to the external threaded sleeve;

[0015] The second nut is connected to the anchor rod.

[0016] By adopting the above technical solution, through the cooperation of the second nut and the conical sleeve, the anchor rod has a double locking effect, thereby ensuring the stability of the tension of the anchor rod inside the concrete structure.

[0017] Specifically, the tail of the tapered sleeve is in the shape of a petal, and at least one group of petals is provided and connected at equal distances along the circumference of the tail end of the tapered sleeve. Expansion joints are formed between the petals. The first nut is threadedly sleeved on the external threaded sleeve, and the second nut is threadedly sleeved on the anchor rod.

[0018] By adopting the above technical solution, the end of the external threaded sleeve is fixed by the first nut, so that the external threaded sleeve is prevented from being subjected to the tension of the anchor rod and continuously moving toward the inside of the anchor plate.

[0019] Specifically, the external structure of the tapered socket is consistent with the shape of the cavity in the tapered cavity.

[0020] The inner cavity diameter of the conical sleeve is consistent with the diameter of the anchor rod, and the diameter of the petal is smaller than the diameter of the anchor rod.

[0021] The beneficial effects of the utility model are as follows: through the assembly consisting of the anchor plate, the anchor head structure and the anchor rod, a set of recyclable unlocking anchor structure with good tensioning and locking effect is provided for the construction of prestressed concrete; through the cooperation of the second nut and the conical sleeve, the anchor rod has a double locking effect, thereby ensuring the stability of the tension of the anchor rod inside the concrete structure; and in the later stage, without cutting off the anchor rod and destroying the anchor head structure, the anchor head structure used for tensioning on the anchor rod can be removed for later recycling, thereby reducing the loss of the anchor head structure, and the anchor head structure can be well recovered when needed, effectively reducing the cost of prestressed concrete construction, and solving the problem that the existing prestressed concrete anchor rod relies on the locking tension of the nut, and after the nut is loosened under the action of external forces such as vibration, the tensioning effect of the anchor rod on the concrete structure is reduced, thereby affecting the stability of the concrete structure.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to reduce costs, such as Figure 1-4 As shown, the anchorage device that can be unlocked and recycled according to the utility model comprises:

[0030] Anchor plate 1;

[0031] Anchor head structures 2, at least one set is provided and arranged on the anchor plate 1;

[0032] At least one group of anchor rods 3 is provided and connected to the anchor head structure 2 .

[0033] The anchor plate 1 is a circular plate structure with a socket.

[0034] When in use, the anchor plate 1, the anchor head structure 2 and the anchor rod 3 provide a set of recyclable unlocking anchor structure with good tensioning and locking effect for the construction of prestressed concrete, so that the anchor rod 3 has a double locking effect and can be recycled, thereby reducing the loss of the anchor head structure 2 and reducing the cost of prestressed concrete construction.

[0035] In order to improve the tension stability, for example, Figure 3 As shown, the utility model also includes that the anchor head structure 2 includes:

[0036] The external thread sleeve 201 is inserted on the anchor plate 1;

[0037] The tapered insert cavity 202 is arranged at the center of the external thread sleeve 201;

[0038] The conical insert sleeve 203 is inserted into the conical insert cavity 202;

[0039] A first nut 206 connected to the external threaded sleeve 201;

[0040] The second nut 207 is connected to the anchor rod 3 .

[0041] When in use, the external threaded sleeve 201 is sleeved on the anchor rod 3 and inserted into the socket of the anchor plate 1. The tail thread of the external threaded sleeve 201 is connected by the first nut 206 to ensure that the external threaded sleeve 201 will not be completely inserted into the socket of the anchor plate 1. The conical sleeve 203 is sleeved on the anchor rod 3 and inserted into the conical insertion cavity 202 of the external threaded sleeve 201. The tail thread of the anchor rod 3 is locked by the second nut 207, so that the anchor rod 3 is tensioned in the concrete.

[0042] The tail of the conical plug sleeve 203 is in the shape of a petal 204 , and at least one group of petals 204 is provided and connected at equal distances along the circumference of the tail end of the conical plug sleeve 203 , and expansion joints 205 are formed between the petals 204 .

[0043] For example, Figure 3 As shown, the utility model also includes that the first nut 206 is threadedly sleeved on the external thread sleeve 201 , and the second nut 207 is threadedly sleeved on the anchor rod 3 .

[0044] The external structure of the tapered insert sleeve 203 is consistent with the cavity shape in the tapered insert cavity 202 .

[0045] The inner diameter of the conical sleeve 203 is consistent with the diameter of the anchor rod 3 , and the diameter of the petal 204 is smaller than the diameter of the anchor rod 3 .

[0046] When the utility model is in use, the anchor rod 3 is inserted into the concrete through the supporting formwork, and then the anchor plate 1 is sleeved on the anchor rod 3, and then the external threaded sleeve 201 is sleeved on the anchor rod 3 and inserted into the insertion hole of the anchor plate 1, and the tail thread of the external threaded sleeve 201 is connected by the first nut 206 to ensure that the external threaded sleeve 201 will not be completely inserted into the insertion hole of the anchor plate 1, and the tapered sleeve 203 is sleeved on the anchor rod 3 and inserted into the tapered insertion cavity 202 of the external threaded sleeve 201, and the tail thread of the anchor rod 3 is locked by the second nut 207, so that the anchor rod 3 is tensioned in the concrete. During the drying and solidification of the concrete, the two ends of the anchor rod 3 will generate contraction force under the influence of the concrete, driving the tapered sleeve 203 to clamp in the tapered insertion cavity 202, and cooperate with the locking of the second nut 207 to make the tensioning effect of the anchor rod 3 more stable;

[0047] When it is necessary to unlock and remove the anchor head part at a later stage, the workers remove the first nut 206 and the second nut 207 in turn, and take down the anchor plate 1. After the anchor plate 1 is taken out, there is a certain amount of space for movement between the external threaded sleeve 201 and the support. The workers push the external threaded sleeve 201 toward the concrete, so that the external threaded sleeve 201 leaves the tapered sleeve 203, causing the tapered sleeve 203 to lose its clamping force on the anchor rod 3. Then the workers remove the tapered sleeve 203 and the external threaded sleeve 201 in turn, and the complete anchor head structure 2 can be obtained, completing the unlocking of the anchor, and recycling it for use in the next project.
