Description

Technical Field

[0001] This utility model relates to a tool for horizontal construction joints that does not require roughening. Background Technology

[0002] With the development of the construction industry, the requirements for construction quality are becoming increasingly stringent, and the deadlines are becoming faster. During the main construction phase, the treatment of horizontal construction joints directly affects the bonding between new and old concrete, thus impacting the overall concrete quality. Furthermore, workers may inadequately remove or clean the concrete during the roughening process, further affecting the quality and appearance of the finished concrete.

[0003] Therefore, a tool for horizontal construction joints that does not require roughening is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing defects and provide a horizontal construction joint roughening tool that can achieve the purpose of eliminating the need for chiseling and improve the joint quality of new and old concrete.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a horizontal construction joint roughening tool, comprising a plate body, one side wall of which is covered with hemispherical protrusions, and multiple slots for engaging with vertical reinforcing bars of the wall are provided on both sides of the plate body; a pre-drilled material outlet is provided on the plate body;

[0006] The plate is fastened to the pre-set vertical reinforcing bars of the wall via a slot.

[0007] Preferably, the plate can be a rigid plastic plate or a thin-walled iron plate.

[0008] Preferably, there can be multiple pre-reserved feed ports, arranged at equal intervals.

[0009] Preferably, the hemispherical protrusion has a diameter of 5mm and a height of 5mm.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This horizontal construction joint roughening tool, by setting one side wall of the plate fully covered with hemispherical protrusions facing downwards, creates a rough concrete contact surface at the horizontal construction joint after pouring, thereby achieving the purpose of eliminating the need for chiseling and improving the joint quality of new and old concrete. Furthermore, this tool is reusable, effectively reducing manual chiseling costs. Since the chiseling process is eliminated for horizontal joints, the construction period is shortened.

[0016] 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.

[0017] like Figure 1-3 As shown, a horizontal construction joint roughening tool includes a plate 1, which can be a rigid plastic plate or a thin-walled iron plate. One side wall of the plate 1 is covered with hemispherical protrusions 2, each with a diameter of 5mm and a height of 5mm. Multiple slots 4 are provided on both sides of the plate 1 for engaging with vertical reinforcing bars 3 in the wall. The plate 1 also has pre-drilled material inlets 5, which can be multiple and evenly spaced. The diameter of each inlet 5 is ≥75mm, and the spacing is 750mm. The plate 1 is engaged with the pre-drilled vertical reinforcing bars 3 in the wall via the slots 4.

[0018] Before pouring concrete, place the plate 1 with one side wall of the hemispherical protrusions 2 facing downwards on the pre-set vertical reinforcing bars 3 of the wall, so that the slot 4 engages with the vertical reinforcing bars 3. Set the elevation to the surface of the cast-in-place concrete slab, ensuring that the rough surface of the tool penetrates 5mm into the surface of the cast-in-place concrete. Pour and vibrate through the pre-drilled material inlet 5. After the concrete strength reaches 1.2MPa, remove the tool, and the horizontal construction joint will form a rough concrete contact surface.

[0019] This horizontal construction joint roughening tool eliminates the need for chiseling. By positioning one side of the plate 1 covered with hemispherical protrusions 2 facing downwards, the hemispherical protrusions 2 create a rough concrete contact surface at the horizontal construction joint after pouring, thus eliminating the need for chiseling and improving the joint quality between new and old concrete. Furthermore, this tool is reusable, effectively reducing manual chiseling costs. By eliminating the chiseling process for horizontal joints, the construction period is shortened.

[0020] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
