Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a tool for one-time forming of drainage dividing joints. Background Technology

[0002] In building construction, a drainage slope refers to the slope created around the exterior walls of a building to drain rainwater and protect the foundation from erosion. To prevent cracking of the drainage slope due to factors such as temperature changes, expansion joints are usually installed on it.

[0003] Currently, the common method for creating expansion joints on aprons is to first mark the surface of the apron and then cut along the marked lines using a cutting tool. However, this method has some drawbacks: firstly, the construction process is cumbersome, requiring marking before cutting, resulting in low construction efficiency; secondly, manual cutting is prone to deviations, making it difficult to guarantee the straightness and dimensional accuracy of the expansion joint, affecting the quality and aesthetics of the apron. Therefore, there is an urgent need for a tool that can achieve one-time forming of expansion joints on aprons, improving construction efficiency and cutting quality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a tool for one-time forming of drainage dividing joints to solve the problems pointed out in the background art.

[0005] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: A tool for one-time forming of drainage dividing joints includes a forming cutter head, a guide plate, and an operating rod. The forming cutter head includes a cutter head body, a guide plate is vertically arranged on the top of the cutter head body, and a cutting blade is provided on one side and the bottom of the cutter head body. The operating rod is connected to the guide plate through a connecting component.

[0006] As a further improvement of this utility model, the connecting assembly includes a rectangular connecting frame and mounting plates symmetrically fixed at both ends of the top of the guide plate. One end of the rectangular connecting frame is rotatably mounted between the two mounting plates, and the other end is detachably connected to an operating rod. An angle adjustment plate is rotatably mounted on one of the mounting plates. An adjustment groove is formed on the angle adjustment plate along its length. An adjustment bolt is fixed on the side of the rectangular connecting frame near the angle adjustment plate. The adjustment bolt passes through the adjustment groove and is threaded with an adjustment nut. The angle of the operating rod can be adjusted by adjusting the position of the adjustment bolt in the adjustment groove.

[0007] As a further improvement of this utility model, one end of the operating rod is fixed with a threaded connecting rod, and the other end is vertically fixed with a handle. The threaded connecting rod passes through the connecting hole on the rectangular connecting frame and is threadedly connected with a locking nut.

[0008] As a further improvement of this utility model, the operating lever includes a telescopic sleeve and a telescopic rod, one end of which is threaded into the telescopic sleeve. The length of the operating lever can be adjusted by adjusting the connection length of the telescopic rod within the telescopic sleeve.

[0009] As a further improvement of this utility model, the material of the blade body is high-strength alloy steel, and the cross-sectional shape of the cutting blade is V-shaped.

[0010] As a further improvement of this utility model, the cutter head body is detachably connected to the guide plate, and a plurality of mounting bolts are fixed on the top of the cutter head body. The mounting bolts pass through the mounting holes on the guide plate and are threaded with mounting nuts.

[0011] The beneficial effects of this utility model are: 1. This utility model has a simple structure, reasonable design, easy operation, high construction efficiency, good forming quality, and strong versatility, and has broad application prospects. In this utility model, the cutter head body has cutting blades on one side and at the bottom, enabling direct cutting of dividing joints on the apron concrete. This achieves one-time forming of the apron dividing joint, eliminating the need for pre-positioning before cutting, simplifying the construction process, and greatly improving construction efficiency.

[0012] 2. The guide plate can guide the movement direction of the cutter head, ensuring the straightness of the cut and improving the dimensional accuracy of the dividing seam and the aesthetics of the drainage.

[0013] 3. The connecting components allow for adjustment of the operating lever angle, enabling operators to adjust their operating posture according to construction needs and their own habits, thus reducing labor intensity. The operating lever adopts a telescopic structure, allowing its length to be adjusted according to actual construction conditions, further improving the tool's versatility.

[0014] 4. The cutter head body and guide plate are detachably connected, making it easy to replace the cutter head body when the cutting edge is worn or damaged, thus reducing operating costs. It also facilitates the replacement of different specifications of pre-formed cutter heads to meet the construction needs of drainage joints of different sizes and shapes, demonstrating strong versatility.
