[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0029] In order to facilitate the understanding of the anchoring template connection structure and the anchoring template provided by the utility model, its application background is first introduced. In the prestressed construction of the box girder, the main purpose of the anchoring at the beam end is to protect the anchor and steel strands after tensioning to ensure the performance and life of the box girder. The traditional anchoring method is the template support method, that is, after the anchor hole is processed, the steel bar with a hook at the end is used to connect the anchor plate and the mesh to achieve the connection and installation of the mesh, and then the end-sealing template is fixed outside the anchor hole, and then concrete is poured. After solidification, the end-sealing template is removed to achieve the sealing of the anchor hole.

[0030] In the related art, the end-sealing formwork is generally reinforced through the corners of the beam ends by means of methods such as horizontal full-length back ribs or vertical U-shaped clamps.

[0031] However, when using the above method, the formwork is bulky and difficult to reinforce, and sometimes some auxiliary measures such as rivets and expansion screws have to be taken, which is a cumbersome and labor-intensive process.

[0032] Based on the above, the utility model provides a sealing and anchoring template connection structure and a sealing and anchoring template, which can greatly simplify the construction process while ensuring the construction quality, saving time and labor in the construction process.

[0033] Combine the following Figure 1-Figure 3 The utility model describes a sealing and anchoring template connection structure and a sealing and anchoring template.

[0034] Reference Figure 1 A sealing anchor template connection structure includes a first connecting rib 10, a second connecting rib 11 and a locking piece 12; wherein, one end of the first connecting rib 10 is fixedly connected to the anchor pad 21 in the anchor hole 20, and the other end opposite thereto is used to connect the mesh in the anchor hole 20; one end of the second connecting rib 11 is detachably connected to the end of the first connecting rib 10 away from the anchor pad 21 along the axial direction, and the other end opposite thereto is detachably connected to the sealing template 22 through the locking piece 12, which is used to lock the sealing template 22 on the anchor hole 20.

[0035] In a specific application scenario, when connecting the end formwork 22, the first connecting rib 10 is first used to connect the mesh and the anchor plate 21 to achieve the connection and fixation of the mesh in the anchor hole 20. On this basis, the end of the second connecting rib 11 is docked with the first connecting rib 10, and the second connecting rib 11 can provide a connection basis for the end formwork 22. After the end formwork 22 is buckled outside the anchor hole 20, the end formwork 22 and the second connecting rib 11 are connected by the locking member 12, so that the end formwork 22 is locked on the anchor hole 20 to achieve the connection and fixation of the end formwork 22 on the anchor hole 20. Subsequently, concrete is filled in the anchor hole 20. After the concrete is cured, the locking member 12 is removed to disassemble the end formwork 22, and then the second connecting rib 11 is pulled axially to separate the second connecting rib 11 from the first connecting rib 10, and the second connecting rib 11 is pulled out of the cured concrete, and finally the hole is sealed.

[0036] Compared with the related art, on the basis of the original structure, the second connecting rib 11 connected with the first connecting rib 10 is used to provide a connection basis for the end template 22. There is no need to use bulky connecting components such as full-length back ribs or U-shaped clips, nor is there any need to use rivets, expansion screws and other components for auxiliary reinforcement, which makes the connection of the end template 22 simpler and more convenient, and the connection process is more time-saving and labor-saving.

[0037] It should be pointed out that the anchor plate 21 is a steel plate or cast iron plate required for anchoring the prestressed tendons during prestressing construction. During prestressing, under the action of the prestressed tendons and anchors, the anchor plate 21 is pressed and fixed to the bottom wall of the anchor hole 20. In the embodiment of the utility model, the anchor plate 21 is used to provide a connection basis for the end capping formwork 22, without involving changes in the structure or principle of the anchor plate 21 itself. Its specific structure and working principle can refer to the prior art, and will not be repeated in the embodiment of the utility model.

[0038] According to different requirements and application scenarios, locking members 12 of different structures or types may be selected to connect the end-capping template 22 .

[0039] In a specific embodiment of the present invention, referring to Figures 1 to 3 The locking member 12 includes a first threaded portion 120 and a first nut 121; wherein the first threaded portion 120 is connected to an end of the second connecting rib 11 away from the first connecting rib 10, and the first nut 121 is used for threaded connection with the first threaded portion 120 passing through the end sealing template 22.

[0040] In actual application, after the second connecting rib 11 is connected to the first connecting rib 10, the end template 22 is buckled on the anchor hole 20, the first threaded portion 120 passes through the end template 22, and then the first nut 121 is tightened. Under the action of the first nut 121, the end template 22 is locked on the anchor hole 20; when disassembling the end template 22, the first nut 121 is unscrewed to remove the end template 22. In this way, the convenience of installing and removing the end template 22 can be improved.

[0041] Specifically, there are a variety of optional connection methods between the first threaded portion 120 and the second connecting rib 11. For example, the two can be welded and fixed, or can be integrally formed. The specific selection can be flexibly made according to actual needs and application scenarios.

[0042] Of course, the locking member 12 includes but is not limited to the structures or forms listed above. Other structures or forms of locking members 12 are also applicable as long as they can lock the end-sealing template 22 on the anchor hole 20.

[0043] The first connecting rib 10 and the second connecting rib 11 are detachably connected via a connecting piece 13 . Similarly, based on different needs and application scenarios, connecting pieces 13 of different structures or forms may be selected to achieve the connection between the first connecting rib 10 and the second connecting rib 11 .

[0044] In a specific embodiment of the present invention, referring to Figure 2 and Figure 3 The connecting member 13 includes a second threaded portion 130 and a second nut 131; wherein the second threaded portion 130 is arranged on one of the first connecting rib 10 and the second connecting rib 11, and the second nut 131 is arranged on the other, and the second nut 131 is threadedly connected to the second threaded portion 130.

[0045] In practical applications, the connection between the first connecting rib 10 and the second connecting rib 11 can be achieved by docking the second nut 131 on one of the first connecting rib 10 and the second connecting rib 11 with the second threaded portion 130 of the other; after the anchor sealing is completed, the end sealing template 22 is removed, and the end of the second connecting rib 11 away from one end of the first connecting rib 10 is pinched with pliers or other tools, and then the second connecting rib 11 is rotated to separate the second threaded portion 130 and the second nut 131, so as to facilitate the second connecting rib 11 to be pulled out axially.

[0046] It is understandable that after the anchoring is completed, the second connecting rib 11 needs to be pulled out, so it is necessary to ensure that the outer diameter of the second nut 131 or the second threaded portion 130 connected to the second connecting rib 11 is not larger than the diameter of the second connecting rib 11, otherwise the second connecting rib 11 may not be pulled out.

[0047] In a specific embodiment of the present invention, the second nut 131 is fixedly connected to the end of the first connecting rib 10 away from the anchor plate 21, and the second threaded portion 130 is connected to the end of the second connecting rib 11. In this way, since the second nut 131 does not need to be disassembled, the restriction of the diameter of the second connecting rib 11 on the size of the second nut 131 can be minimized, thereby ensuring the stability of the connection between the first connecting rib 10 and the second connecting rib 11.

[0048] Specifically, there are a variety of optional connection methods between the second nut 131 and the first connecting rib 10. For example, the two can be welded, integrally formed, or connected by threads. The specific selection can be flexibly made according to actual needs and application scenarios.

[0049] Specifically, there are a variety of optional connection methods between the second threaded portion 130 and the second connecting rib 11. For example, the two can be fixed by welding, or the second threaded portion 130 can be formed by threading the end of the second connecting rib 11, so that the second threaded portion 130 and the second connecting rib 11 are integrally formed. The specific selection can be flexibly made according to actual needs and application scenarios.

[0050] It is understandable that the connecting member 13 includes but is not limited to the structures or forms listed above, and other structures or forms of connecting members 13 are applicable as long as they can achieve axially detachable connection between the first connecting rib 10 and the second connecting rib 11.

[0051] In order to facilitate the connection of the mesh in the anchor hole 20, in a specific embodiment of the utility model, a threaded hole 210 is provided on the anchor plate 21, and a third threaded portion 100 is provided at one end of the first connecting rib 10 away from the second connecting rib 11, and the third threaded portion 100 is threadedly connected to the threaded hole 210 on the anchor plate 21, and a hook end 101 is provided at one end of the first connecting rib 10 away from the anchor plate 21 for hooking the mesh.

[0052] In actual applications, the third threaded portion 100 on the first connecting rib 10 is threadedly connected to the threaded hole 210 on the anchor plate 21 to achieve the connection and fixation of the first connecting rib 10 on the anchor plate 21, and then the mesh is hooked through the hook end 101 at the end of the first connecting rib 10 to achieve the connection and fixation of the mesh in the anchor hole 20.

[0053] Specifically, there are a variety of optional connection methods between the third threaded portion 100 and the first connecting rib 10. For example, the two can be fixed by welding, or the third threaded portion 100 can be formed by threading the end of the first connecting rib 10, so that the third threaded portion 100 and the first connecting rib 10 are integrally formed. The specific selection can be flexibly made according to actual needs and application scenarios.

[0054] In a specific embodiment of the present invention, the hook end 101 and the first connecting rib 10 can be fixed by welding, or can be integrally formed, or can be connected in a detachable manner. Specifically, they can be flexibly configured according to actual needs and application scenarios.

[0055] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present invention can be combined.

[0056] The anchoring template provided by the present invention is described below. The anchoring template described below and the anchoring template connection structure described above can be referred to each other.

[0057] A sealing anchor template comprises an anchor pad 21, a mesh and an end-sealing template 22; wherein the anchor pad 21 is arranged at the bottom of an anchor hole 20, and the mesh is arranged in the anchor hole 20; and also comprises the above-mentioned sealing anchor template connection structure for connecting the anchor pad 21, the mesh and the end-sealing template 22.

[0058] The novelty of the utility model is that when the end-capping template 22 is connected, the first connecting rib 10 is first used to connect the mesh and the anchor pad 21 to achieve the connection and fixation of the mesh in the anchor hole 20. On this basis, the end of the second connecting rib 11 is butted with the first connecting rib 10, and the second connecting rib 11 can provide a connection basis for the end-capping template 22. After the end-capping template 22 is buckled on the anchor hole 20, the end-capping template 22 and the second connecting rib 11 are connected by the locking member 12, so that the end-capping template 22 is locked on the anchor hole 20, and the connection and fixation of the end-capping template 22 on the anchor hole 20 is achieved, and then the anchor hole 20 is filled with concrete. After the concrete solidifies, the locking piece 12 is removed to disassemble the end-capping formwork 22, and then the second connecting rib 11 is pulled axially to separate the second connecting rib 11 from the first connecting rib 10, and the second connecting rib 11 is pulled out of the solidified concrete, and finally the hole is sealed. Compared with the related art, the second connecting rib 11 connected to the first connecting rib 10 provides a connection basis for the end-capping formwork 22, without the need to use bulky connecting components such as full-length back ribs or U-shaped clips, and without the need to use rivets, expansion screws and other components for auxiliary reinforcement, so that the connection of the end-capping formwork 22 is simpler and more convenient, and the connection process is more time-saving and labor-saving.
