Description

Technical Field

[0001] The utility model relates to the technical field of cap production, in particular to a detachable combined mould for secondary pouring holes of a stay cable cap. Background Art

[0002] In large-scale fish-photovoltaic hybrid power generation projects, the dense pile foundations of traditional fixed supports in fish ponds can hinder water flow. To address this, the fixed support method was replaced with a flexible cable support system. This cap structure greatly reduces the number of pile foundations, but this system has the characteristics of high clearance and large span, so it has extremely high requirements for the stability of the system. Therefore, a cable-stayed cap is used as the anchor point of the flexible cable structure. An anchor point connected to the cable is set at the top center of the cap. Variable diameter secondary casting holes are set on both sides of the cap for pouring pile foundations in the fish pond. The reasons for the variable diameter of the secondary casting holes are: 1. After the secondary casting of the cap and the pile foundation, the upper part of the secondary casting hole is larger than the lower part to prevent the pile foundation from sinking and separating from the cap; 2. When the cap anchor point is connected to the cable structure, an upward pulling force is generated. The variable diameter secondary casting method prevents the cap from separating from the pile foundation. However, due to the obstruction of the upper steel mesh of the cap and the diameter of the secondary casting hole being larger at the top and smaller at the bottom, it cannot be removed using traditional molds. Utility Model Content

[0003] The utility model aims to solve the above problems, thereby providing a detachable combined mold that is easy to dismantle and is used for secondary pouring holes of a cable-stayed cable cap.

[0004] The utility model solves the above problems by adopting the following technical solutions:

The lower casing is composed of several splicing plates connected along the circumferential direction, and the bottom of the upper casing is provided with several reinforcement holes along the circumferential direction for placing on the upper steel mesh of the pedestal.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0007] The lower casing is set in advance, and then the steel mesh is arranged on the outside of the lower casing. Subsequently, the reinforcement opening of the upper casing is clamped on the upper steel mesh and opposite to the lower casing to cast the pedestal. After the casting is completed, the upper casing can be pulled out directly at the top, and the connections of the adjacent splicing plates are untied and taken out from under the pedestal respectively. The split module is dismantled, which solves the problem of not being able to dismantle the entire pedestal.

[0009] Furthermore, a connecting plate is longitudinally provided on the inner wall of the splicing plate and at the intersection of two adjacent splicing plates, and a plurality of pads are longitudinally provided between two adjacent connecting plates. Connecting bolts penetrate both the connecting plate and the pads.

[0010] Furthermore, a gap of 5-8 mm is left between adjacent spliced ​​plates.

[0011] Furthermore, the spacing between adjacent connecting splints is between 40-50 mm.

[0012] Furthermore, the bottom diameter of the upper casing is equal to the top diameter of the lower casing.

[0013] Furthermore, the height of the upper casing located above the reinforcement opening is greater than the thickness of the upper concrete protective layer of the cap. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0019] A detachable combined mold for secondary pouring holes of a cable-stayed cap comprises an upper casing 1 and a lower casing which are both frustum-shaped. The lower casing is composed of a plurality of splicing plates 2 connected along a circumferential direction. There are four splicing plates 2 in total. The bottom of the upper casing 1 is provided with a plurality of reinforcement holes 11 along a circumferential direction for placing on the upper steel mesh of the cap.

[0020] Furthermore, a connecting splint 21 is longitudinally arranged on the inner wall of the splicing plate 2 and at the intersection of two adjacent splicing plates 2. A number of pads 3 are longitudinally arranged between the two adjacent connecting splints 21. Connecting bolts are passed through the connecting splint 21 and the pads 3. The two adjacent splicing plates 2 are connected by the pads 3 and the connecting splint 21. When disassembling, the connecting bolts are removed and the splicing plates 2 can be taken out separately.

[0021] Furthermore, a gap of 5-8 mm is left between adjacent splicing plates 2 to avoid mutual squeezing force during dismantling causing difficulty in dismantling.

[0022] Furthermore, the spacing between adjacent connecting splices 21 is between 40-50 mm, which prevents the splicing panels 2 from moving inwards due to the squeezing of concrete during dismantling and interfering with the connecting splices 21 on the adjacent splicing panels 2 .

[0023] Furthermore, the bottom diameter of the upper casing 1 is equal to the top diameter of the lower casing.

[0024] Furthermore, the height of the upper casing 1 above the reinforcement 11 opening is greater than the thickness of the upper concrete protective layer of the cap 4, which is convenient for clamping and disassembly.

[0025] The lower casing is set in advance, and then the steel mesh is arranged on the outside of the lower casing. Subsequently, the reinforcement opening 1 of the upper casing 1 is clamped on the upper steel mesh 5 and opposite to the lower casing, and the base 4 is cast. After the casting is completed, the upper casing 1 can be pulled out directly at the top, and the connection between the adjacent splicing plates 2 is untied and taken out from under the base 4 respectively. The split module is dismantled, which solves the problem of not being able to dismantle the entire module.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. Any equivalent changes made using the contents of the present invention specification and its drawings are included in the scope of the present invention.
