Description

A carbon fiber plate tensioning anchor end triangular area carbon plate adhesive filling mold Technical Field

[0001] This utility model relates to the technical field of old bridge repair and reinforcement engineering, and more specifically to a carbon fiber plate adhesive filling mold for the triangular area of ​​the tensioning and anchoring end of a carbon fiber plate. Background Technology

[0002] Carbon fiber plate tensioning is a technique that utilizes the high strength properties of carbon fiber plates to enhance the load-bearing capacity of structures by applying prestress through tensioning. It is widely used in the reinforcement of bridges, buildings, and other structures.

[0003] Carbon fiber sheet tensioning involves stretching carbon fiber sheets to the design stress using tensioning equipment and then anchoring them to the structure, thereby applying prestress to the structure. This prestress can alter the internal force distribution of the structure, improving its load-bearing capacity and crack resistance.

[0004] Common methods for tensioning carbon fiber plates include single-end tensioning and double-end tensioning. After single-end tensioning, a triangular area naturally forms between the anchoring end and the bottom of the beam along the longitudinal length of the carbon fiber plate. This triangular area is typically sealed with carbon fiber adhesive. The traditional method involves applying carbon fiber adhesive in layers to the carbon fiber plate, but this method cannot guarantee a dense filling or an aesthetically pleasing appearance.

[0005] Therefore, in order to prevent the colloid from leaking and the appearance from becoming irregular after hardening, a small mold needs to be made for shaping before injecting the carbon plate adhesive. Summary of the Invention

[0006] In view of this, the present invention provides a carbon fiber plate adhesive filling mold for the triangular area of ​​the tension anchorage end of carbon fiber plate, which can be widely used for filling and shaping carbon fiber plate adhesive in the triangular area of ​​the tension anchorage end of carbon fiber plate in various old bridge reinforcement and repair projects.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A carbon fiber plate tensioning anchoring end triangular area carbon plate adhesive filling mold, including a side mold and clamping components;

[0009] The bottom formwork is a triangular carbon fiber plate tensioned on the bottom surface of the beam. There are two side forms, which are symmetrical on both sides of the triangular carbon fiber plate. The upper ends of the two side forms abut against the bottom surface of the beam, and the face plates abut against the two side ends of the triangular carbon fiber plate. The clamping members are clamped on the face plates of the two side forms to secure the two side forms to the triangular carbon fiber plate.

[0010] The beneficial effects of this utility model are that by using the tensioned carbon fiber plate as the bottom mold and clamping the two side molds on both sides of the bottom mold with clamping parts, the defects such as carbon plate adhesive leakage and irregular appearance after hardening are solved, and the quality is controllable and the effect is good.

[0011] Preferably, the clamping component includes a U-shaped clip, and the two side molds are embedded in the U-shaped groove of the U-shaped clip. The two side molds are clamped to both sides of the carbon fiber plate in the triangular area by the U-shaped clip, thereby realizing the installation of the beam formwork.

[0012] Preferably, the device further includes a locking screw. One side of the U-shaped clip abuts against the panel of one of the side molds, and the other side of the clip has a screw hole. The threaded end of the locking screw is screwed into the screw hole and abuts against the other side mold. The locking screw ensures the U-shaped clip securely holds the side mold, preventing mold deformation due to the U-shaped clip falling off, and ensuring the filling quality and aesthetics of the carbon fiber adhesive.

[0013] Preferably, a wedge-shaped block is embedded between the bottom surface of the triangular carbon fiber plate at its tensioning end and the inner bottom wall of the U-shaped card. The wedge-shaped block acts as a positioning block for the tensioning end of the U-shaped card, ensuring the overall stability of the mold.

[0014] Preferably, the side mold is a carbon fiber plate.

[0015] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a carbon fiber plate adhesive filling mold for the triangular area of ​​the carbon fiber plate tensioning and anchoring end. This reduces bridge defects such as adhesive leakage and irregular appearance after hardening, ensuring that the carbon fiber plate adhesive is dense, well-shaped, and leak-free after curing. Fundamentally, it achieves the inherent safety of the bridge superstructure; ensures the quality of carbon fiber plate adhesive filling in the triangular area of ​​the carbon fiber plate tensioning and anchoring section; and extends the service life of the entire bridge beam after repair and reinforcement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As shown in Figures 1-3, this utility model embodiment discloses a carbon fiber plate adhesive filling mold for the triangular area of ​​the tension anchoring end of a carbon fiber plate, including a side mold 3 and a clamping component 4.

[0024] The bottom of the beam 1 is tensioned and the triangular carbon fiber plate 2 is used as the bottom mold; there are two side molds 3, which are symmetrically placed on both sides of the triangular carbon fiber plate 2. The upper ends of the two side molds 3 abut against the bottom surface of the beam 1, and the panels abut against the two sides of the triangular carbon fiber plate 2; the clamping parts 4 are clamped on the panels of the two side molds 3 to make the two side molds 3 and the triangular carbon fiber plate 2 secure.

[0025] As shown in the figure, the carbon plate adhesive filling method in this embodiment is as follows: carbon fiber plate tensioning → the tensioned carbon fiber plate is used as the bottom mold → carbon plate adhesive is injected into the triangular carbon fiber plate in the first stage → existing carbon limiting plate scraps are used to assemble as one side mold in the longitudinal direction → pre-shaping → continuous injection of carbon plate adhesive in the second stage → adhesive filling → existing carbon plate scraps are used to assemble as the other side mold in the longitudinal direction → pressing the adhesive into the mold → final shaping → fastening with fasteners.

[0026] In practical applications, after the carbon fiber plate is tensioned, it is used as a bottom mold, and the first stage of carbon fiber adhesive is injected into the bottom mold. Then, the remaining carbon fiber plate is used as a longitudinal side mold. First, one side mold of the longitudinal direction of the carbon fiber plate in the triangular area is installed. The carbon fiber plate in the triangular area is temporarily fixed to the side mold installed. The temporary fixing method can be by binding the carbon fiber plate in the triangular area to the side mold, or by setting a stop in the beam for temporary fixing. After the side mold on one side is temporarily fixed, the carbon fiber adhesive injected in the first stage can be pre-shaped. Then, the second stage of carbon fiber adhesive is injected. When the adhesive fills the entire triangular area, the other side mold in the longitudinal direction is installed, and the adhesive is squeezed into the triangular area enclosed by the two side molds and the carbon fiber plate in the triangular area for final shaping. Finally, the two side molds and the carbon fiber plate in the triangular area are fastened with fasteners. After the carbon fiber adhesive solidifies, the template is removed, and the carbon fiber adhesive filling operation in the triangular area is completed.

[0027] In this embodiment, the clamping component 4 includes a U-shaped clip 41, and the two side molds 3 are embedded in the U-shaped groove of the U-shaped clip 41. By clamping and fixing the two side molds to the carbon fiber plate in the triangular area through the U-shaped clip, the final shaping of the entire mold can be achieved.

[0028] To further optimize the above technical solution and ensure the firmness of the connection between the side mold and the carbon fiber plate in the triangular area, a locking screw 42 is also included. One side of the groove wall of the U-shaped clip 41 abuts against the panel of one of the side molds 3, and the other side of the groove wall is provided with a screw hole. The threaded end of the locking screw 42 is screwed from the screw hole and abuts against the other side mold 3.

[0029] To further optimize the above technical solution, a wedge block 5 is embedded between the bottom surface of the triangular carbon fiber plate 2 at its tensioning end and the inner bottom wall of the U-shaped card 41.

[0030] After testing, compared with the existing construction methods, the construction time was shortened by 1 / 6 to 1 / 3 by using this filling mold, and the carbon plate adhesive filling and shaping of each hole in the carbon plate triangle area of ​​half width can save direct costs of 150-300 yuan.

[0031] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
