Description

Technical Field

[0001] This utility model relates to the field of civil engineering, specifically to a pouring height auxiliary device for UHPC. Background Technology

[0002] Currently, with the continuous development and improvement of bridge construction technology, the molding quality of bridge superstructure components needs to be controlled. During the pouring of bridge superstructure components, over-pouring of 0.5m-1.0m is necessary to ensure the molding quality of the concrete within the superstructure components. Since bridge superstructure components generally have a certain depth during construction, controlling the pouring height is difficult. This is often done manually based on experience, but differences in the experience levels of on-site construction personnel can lead to accidents such as under-pouring and over-pouring. Under-pouring is a serious quality defect, while over-pouring results in concrete waste.

[0003] Currently, most methods for detecting the height of concrete during the pouring process rely on concrete monitoring instruments. These instruments typically use sensors to monitor the level of the poured concrete in the superstructure of bridges. Consequently, they are expensive, complex in structure, and costly to repair if damaged, resulting in long repair cycles and very high operating costs.

[0004] Therefore, we propose a pouring height assist device for UHPC. Summary of the Invention

[0005] To address the aforementioned shortcomings of the existing technology, this utility model provides a pouring height auxiliary device for UHPC.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: A UHPC pouring height auxiliary device includes: an outer measuring tube, which is cylindrical and has an outer scale on its wall along the axial direction; an inner measuring component, which is slidably disposed inside the outer measuring tube and has a density less than that of the concrete slurry, and has an inner scale on its inner measuring component, which extends out from the top of the outer measuring tube and displays the inner scale as the outer measuring tube is inserted into the concrete slurry; and a fixing component, which is disposed on the circumference of the outer measuring tube and fixes the outer measuring tube on the working plane.

[0007] In use, the inner measuring component, equipped with an outer measuring tube, is inserted into the space enclosed by the casting template of the bridge superstructure until it extends from the top of the outer measuring tube. At this point, by reading the outer scale above the top of the bridge superstructure and the inner scale where the inner measuring component extends, and then subtracting the readings from the total length of the outer measuring component, the liquid level of the concrete slurry inside the bridge superstructure can be obtained. This provides liquid level height assistance during the casting process. Since the density of the inner measuring component is lower than that of the concrete slurry, it will float when inserted into the concrete slurry surface together with the outer measuring tube. No sensors are required, making it inexpensive and not easily damaged, resulting in very low operating costs.

[0008] Further defined, the internal measuring component includes a float, a connecting rod, a limiting block, and a rolling structure; the float is fixedly located at the bottom end of the connecting rod and has a clearance fit with the inner diameter of the outer measuring tube; the limiting block is located at the top end of the connecting rod, and the outer diameter of the limiting block is the same as the outer diameter of the outer measuring tube; the connecting rod and the float are located inside the outer measuring tube; the rolling structure is located on the connecting rod above the float, so that the connecting rod is in rolling connection with the inner wall of the outer measuring tube; when the limiting block contacts the top end of the outer measuring tube, the bottom surface of the float and the bottom opening of the outer measuring tube are located on the same horizontal plane; the inner scale is opened on the circumferential surface of the connecting rod along the axial direction of the connecting rod.

[0009] By setting up a float, when the float encounters concrete slurry, the float will float because its density is less than that of the concrete slurry. This will push the connecting rod and the limiting block to rise and extend beyond the top of the outer measuring tube. The rolling structure makes the relative movement between the connecting rod and the outer measuring tube smoother, reduces the resistance to the float's ascent, and makes it more convenient to use.

[0010] Further defining the structure, the rolling structure includes a mounting block, mounting ears, and rolling wheels. The mounting blocks are positioned opposite each other on the circumferential surface of the connecting rod, the mounting ears are located on the outer end face of the mounting blocks, and the rolling wheels are rotatably connected to the mounting ears via a rotating shaft. The distance between the outer ends of the two rolling wheels is clearance-fitted with the inner diameter of the outer measuring tube. By setting the rolling wheels, during the floating process of the float, the rolling wheels roll on the inner wall of the outer measuring tube, thereby reducing the floating resistance of the float. The structure is simple.

[0011] Furthermore, the starting point of the outer scale is at the top of the outer measuring tube, and the starting point of the inner scale is at the top of the connecting rod. This setting of the starting points of the outer and inner scales allows for direct observation of the outer scale extending from the top of the upper component of the bridge and the inner scale extending from the top of the outer measuring tube, making readings more convenient.

[0012] Further defining the fixing component, it includes a fixing ring, a fixing bolt, a fixing arm, a fixing block, and a fixing cone; the inner diameter of the fixing ring and the outer diameter of the outer measuring tube are clearance-fitted; one end of the fixing arm is fixedly connected to the fixing ring and the other end is fixedly connected to the fixing block; the fixing block has a vertically through fixing hole; the fixing cone passes through the fixing hole to fix the fixing component on the working plane; the circumferential surface of the fixing ring has a threaded hole for the fixing bolt to be screwed in; the outer measuring tube is screwed into the threaded hole by the fixing bolt and fixed inside the fixing ring.

[0013] By inserting the external measuring tube into the fixing ring and fixing it with fixing bolts, the external scale is fixed. Then, through the fixing block and fixing cone, the fixing cone passes through the fixing hole and into the working plane, and the fixing assembly is fixed as a whole, preventing the external measuring tube from falling into the upper structure of the bridge, and also saving manpower.

[0014] Furthermore, the fixing component also includes a reading aid plate; the bottom surface of the fixing block is recessed and has a sliding groove that runs through the front and rear sides, the reading aid plate is slidably disposed in the sliding groove, and the plate surface of the reading aid plate has a strip-shaped through groove for the fixing cone to pass through; since there is a certain gap between the outer measuring tube and the template of the upper part of the bridge, and most people look down from a high place, it is relatively troublesome to read the accurate reading of the outer scale. By setting up the reading aid plate, the reading aid plate slides towards the outer measuring tube through the sliding groove, and contacts the outer measuring tube in a horizontal state. The contact position is the degree of the outer scale, which makes it convenient for people to read the degree of the outer scale and is more convenient to use.

[0015] The beneficial effects of this utility model are as follows: by setting an outer measuring tube and an inner measuring component, and by reading the readings of the outer and inner scales, the distance between the liquid level of the concrete slurry and the top of the upper component of the bridge can be directly calculated. No sensor is required, the structure is simple, the cost is low, and it is easy to use. Attached Figure Description

[0018] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0019] Example: like Figures 1-4As shown, a UHPC pouring height auxiliary device includes an outer measuring tube 1, an inner measuring component 2, and a fixing component 3. The outer measuring tube 1 is cylindrical and has an outer scale along the axial direction on its wall. The inner measuring component 2 is slidably disposed inside the outer measuring tube 1 and has a density less than that of the concrete slurry. The inner measuring component 2 has an inner scale. The inner measuring component 2 includes a float 21, a connecting rod 22, a limiting block 23, and a rolling structure 24. The float 21 is fixedly disposed at the bottom end of the connecting rod 22 and has a clearance fit with the inner diameter of the outer measuring tube 1. The limiting block 23 is disposed at the top end of the connecting rod 22, and the outer diameter of the limiting block 23 is... The outer diameters of the measuring tubes 1 are the same. The connecting rod 22 and the float 21 are located inside the outer measuring tube 1. The rolling structure 24 is located on the connecting rod 22 above the float 21, so that the connecting rod 22 is in rolling connection with the inner wall of the outer measuring tube 1. When the limiting block 23 contacts the top of the outer measuring tube 1, the bottom surface of the float 21 and the bottom opening of the outer measuring tube 1 are on the same horizontal plane. The inner scale is opened on the circumferential surface of the connecting rod 22 along the axial direction of the connecting rod 22. The starting scale of the outer scale is at the top of the outer measuring tube 1, and the starting scale of the inner scale is at the top of the connecting rod 22. The rolling structure 24 includes a mounting block 241 and a mounting ear 242. The connecting rod 22 has two rollers 243 and two mounting blocks 241, which are positioned opposite each other on the circumferential surface of the connecting rod 22. Mounting ears 242 are located on the outer end face of the mounting blocks 241. The rollers 243 are rotatably connected to the mounting ears 242 via a rotating shaft. The distance between the outer ends of the two rollers 243 is clearance-fitted with the inner diameter of the outer measuring tube 1. A fixing assembly 3 is used to fix the outer measuring tube 1 on the working plane. The fixing assembly 3 includes a fixing ring 31, a fixing bolt 32, a fixing arm 33, a fixing block 34, a fixing cone 35, and a reading aid plate 36. The inner diameter of the fixing ring 31 is clearance-fitted with the outer diameter of the outer measuring tube 1, and one end of the fixing arm 33 is fixed... One end is fixed to the fixed ring 31, and the other end is fixed to the fixed block 34. The fixed block 34 has a vertical through-hole 341. The fixed cone 35 passes through the fixed hole 341 to fix the fixed component 3 on the working plane. The circumferential surface of the fixed ring 31 has a threaded hole for the fixed bolt 32 to be screwed in. The outer measuring tube 1 is screwed into the threaded hole by the fixed bolt 32 and fixed in the fixed ring 31. The bottom surface of the fixed block 34 has an inwardly recessed groove 342 that passes through the front and rear sides. The reading aid plate 36 is slidably disposed in the groove 342, and the plate surface of the reading aid plate 36 has a strip-shaped through groove for the fixed cone 35 to pass through.

[0020] In this embodiment, the structure of the fixing cone 35 is suitable for fixing on a soil surface. However, in some embodiments, if fixing on a hard surface is required, the fixing cone 35 in the fixing assembly 3 can be replaced with a bolt to achieve fixing.

[0021] In use, the inner measuring component 2, equipped with an outer measuring tube 1, is inserted into the space enclosed by the casting template of the bridge superstructure until it protrudes from the top of the outer measuring tube 1. At this point, by reading the outer scale above the top of the bridge superstructure and the inner scale where the inner measuring component 2 protrudes, and then subtracting the readings from the total length of the outer measuring component, the liquid level of the concrete slurry inside the bridge superstructure can be obtained. This provides assistance in determining the liquid level during the casting process. Since the density of the inner measuring component 2 is less than that of the concrete slurry... Therefore, when the inner measuring component 2 is inserted into the concrete slurry surface along with the outer measuring tube 1, it will float up. No sensors are required, making it inexpensive and durable, resulting in very low operating costs. By setting a float 21, when the float 21 encounters the concrete slurry, it will float because its density is less than that of the concrete slurry. This will push the connecting rod 22 and the limiting block 23 upwards, extending them beyond the top of the outer measuring tube 1. The rolling structure 24 allows for smoother relative movement between the connecting rod 22 and the outer measuring tube 1, reducing the resistance to the float 21's upward movement. More convenient; by setting the rolling wheel 243, during the upward movement of the float 21, the rolling wheel 243 rolls on the inner wall of the outer measuring tube 1, thereby reducing the upward resistance of the float 21, and the structure is simple; by setting the starting scale of the outer and inner scales in this way, the outer scale extending from the top of the upper component of the bridge and the inner scale extending from the top of the outer measuring tube 1 can be directly seen, making it easier to read; by passing the outer measuring tube 1 through the fixing ring 31 and fixing it with the fixing bolt 32, the outer scale is fixed at this time, and then through the fixing block 34 and the fixing cone 35, the fixing cone 35 passes through The outer measuring tube 1 is inserted through the fixing hole 341 into the working plane to fix the fixing assembly 3 as a whole, preventing the outer measuring tube 1 from falling into the upper part of the bridge and saving manpower. Since there is a certain gap between the outer measuring tube 1 and the template of the upper part of the bridge, and most people look down from a high place, it is difficult to read the accurate reading of the outer scale. By setting up the reading aid plate 36, the reading aid plate 36 slides to the outer measuring tube 1 through the slide groove 342 and contacts the outer measuring tube 1 in a horizontal state. The contact position is the degree of the outer scale, which makes it convenient for people to read the degree of the outer scale and makes it easier to use.
