Description

Technical Field

[0001] The invention relates to the technical field of construction engineering measurement tools, and in particular to a tool for controlling the thickness of concrete when pouring concrete in road construction. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. It refers to cement concrete obtained by mixing cement as cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is also called ordinary concrete. It is widely used in civil engineering. Premixed concrete is in a flowable state for a certain period of time. It can be poured into the mold and compacted and solidified to form structures or components of various shapes and sizes. After forming, cement and water react for a period of time to harden the concrete. The hardened concrete has the properties of general stone, so concrete is also called concrete, which means artificial stone.

[0003] When pouring concrete, it is necessary to carefully control the thickness of the poured concrete to meet the quality requirements of the project. When pouring concrete on the top plate of a cast-in-place concrete structure, in order to control the thickness of the top plate concrete, a 50cm control point is generally drawn on the column reinforcement. When pouring concrete, an engineering line is drawn between the two points, and a tape measure or a 50cm long PVC pipe is used to measure the height. The disadvantage of this method is that the measurement is cumbersome, the control line will swing up and down with the environment, and the measurement accuracy is inaccurate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1 like Figure 1 to Figure 6 As shown, this embodiment proposes a tool for controlling the thickness of concrete when pouring concrete in road construction, including a shell 1, a sliding component 3 is installed on the top of the shell 1, a knob 4 is rotatably connected to the top of the shell 1 through the sliding component 3, a connecting rod 5 is fixedly connected to the bottom of the knob 4, and a rotating component 6 is installed on the outside of the connecting rod 5; a threaded rod 2, the threaded rod 2 is slidably connected to the inside of the shell 1, a positioning component 7 is installed on the outside of the threaded rod 2, a ball slider 8 is driven and connected to the outside of the threaded rod 2, and a movable plate 9 is fixedly connected to the outside of the ball slider 8. The inner diameter of the shell 1 is larger than the outer diameter of the threaded rod 2, and a fixed plate 10 is fixedly connected to the outside of the shell 1. The movable plate 9 and the fixed plate 10 have the same cross-sectional size when viewed from above, the bottom end of the threaded rod 2 is fixedly connected to a limiting plate 11, and a plurality of anti-slip grooves are provided on the outside of the knob 4. The threaded rod 2 is inserted into the poured concrete, and the top of the concrete pushes the movable plate 9 to make the ball slider 8 move outside the threaded rod 2, so that the concrete thickness of the structural plate can be stably measured.

[0018] Furthermore, the sliding assembly 3 includes a sliding ring 31, which is fixed on the top of the outer shell 1. A guide rail 32 is provided at the bottom of the knob 4. The inside of the guide rail 32 is slidably connected to the outside of the sliding ring 31. Rotating the knob 4 causes the guide rail 32 to slide outside the sliding ring 31, so that the knob 4 and the outer shell 1 rotate relative to each other, facilitating the subsequent extension of the threaded rod 2.

[0019] Furthermore, the rotating assembly 6 includes a limit rod 1 61, which is fixed at the lower end of the connecting rod 5, and the lower end of the connecting rod 5 is fixedly connected to a limit rod 2 62. A spiral groove 1 63 is provided inside the threaded rod 2, and a spiral groove 2 64 is provided inside the threaded rod 2. The outside of the limit rod 1 61 is slidably connected to the inside of the spiral groove 1 63 and the spiral groove 2 64, and the outside of the limit rod 2 62 is slidably connected to the inside of the spiral groove 1 63 and the spiral groove 2 64. The spiral groove 1 63 and the spiral groove 2 64 have the same pitch and are consistent in size. Rotating the knob 4 causes the guide rail 32 to slide outside the sliding ring 31, and the knob 4 drives the connecting rod 5 to cause the limit rod 1 61 and the limit rod 2 62 to slide inside the spiral groove 1 63 and the spiral groove 2 64, and cooperate with the positioning assembly 7 to move the threaded rod 2 downward.

[0020] Furthermore, the positioning assembly 7 includes a limit block 71, which is fixed inside the outer shell 1. The upper end of the threaded rod 2 extends to the inside of the outer shell 1 and is fixedly connected to a fixing ring 72. A sliding groove 73 is provided on the outside of the fixing ring 72. The inside of the sliding groove 73 is slidably connected to the outside of the limit block 71, so that the limit block 71 slides inside the sliding groove 73 on the fixing ring 72. Under the limitation of the fixing ring 72 and the limit block 71, the threaded rod 2 moves downward to reach the end position, which is convenient for measuring the concrete thickness of the subsequent structural plate.

[0021] In this embodiment, when it is needed, the knob 4 is rotated to make the guide rail 32 slide outside the sliding ring 31, and the knob 4 drives the connecting rod 5 to make the limit rod 1 61 and the limit rod 2 62 slide inside the spiral groove 1 63 and the spiral groove 2 64, so that the limit block 71 slides inside the sliding groove 73 on the fixed ring 72, and the threaded rod 2 moves downward under the limitation of the fixed ring 72 and the limit block 71. After reaching the end position, the threaded rod 2 is inserted into the poured concrete, and the top of the concrete pushes the movable plate 9 to make the ball slider 8 move outside the threaded rod 2, which can stably measure the concrete thickness of the structural plate and improve the construction efficiency. At the same time, it reduces the material loss rate, reduces labor input, and controls the construction cost.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
