Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and in particular to a concrete placement elevation control device. Background Technology

[0002] Finishing the concrete pour is a crucial step. Its core function is not only to control the flatness, elevation, and shape of the concrete surface to meet design requirements, but also to ensure the integrity and durability of the structure. Controlling the finishing elevation is especially important when pouring large-volume concrete (large-volume concrete refers to concrete structures with a minimum geometric dimension of 1m; a large concrete pour surface refers to a concrete pouring surface with an area exceeding 5000㎡). Uneven finishing often leads to non-straight horizontal construction joints. Traditionally, the finishing elevation is controlled by manually spraying paint, but this method is prone to inaccuracies.

[0003] The prior art (publication number: CN202559717U, patent name: large template device with sample receiving rack) discloses a large template device with a sample receiving rack. Although the sample receiving rack solves the problem of inaccurate control during manual paint spraying, it still has the following problems: Its adjusting screw passes through the template frame and is fixed to the adjusting screw at the bottom of the template frame with a nut. After the concrete is poured and the template frame is closed, the nut and adjusting screw section at the bottom of the template frame will cause damage to the concrete. This sample rack is only suitable for templates of fixed thickness. The height of the sample rack can only be adjusted by adjusting the adjusting screw to meet the design elevation requirements. There are bound to be errors when the L-shaped connecting plate used to fix the adjusting screw is opened. These errors will cause the sample rack to not be able to be installed smoothly inside the template and will also cause unevenness in the storage. The sample rack for receiving concrete is made of angle steel. The width of the angle steel is limited, making it difficult to ensure that the horizontal construction joints of large-volume concrete are straight. Utility Model Content

[0011] Preferably, the adjusting receiving component is made of angle steel and includes a first straight edge and a second straight edge that are perpendicular to each other and have their openings facing upwards. The first end face of the connecting rod is welded to the first straight edge, or multiple non-penetrating fixing holes are arranged side by side along the length of the first straight edge, and the first end of the connecting rod is fixedly connected to the first straight edge through the fixing holes. A sliding groove is provided between two adjacent connecting rods on the first straight edge, with the two ends of the sliding groove being far apart from each other and extending to the connecting rod.

It not only avoids damaging the concrete surface but also increases the control area for final placement, thus improving its applicability. When the connecting rod connects to the adjusting final placement component, the connecting rod does not pass through the first straight edge of the adjusting final placement component, keeping the bottom of the first straight edge flat. After the concrete is poured and finalized, the concrete surface remains flat without causing damage. The design of the rotating final placement system increases the final placement area; the reference strip not only serves as a final placement elevation control but also enables the leveling of the concrete surface. The slotted hole design of the pad plate improves the applicability of this control device, allowing it to adapt to templates of different thicknesses. Attached Figure Description

The rotating placement system is rotatably connected to the adjustable placement system and is used to increase the concrete placement surface.

[0031] Each set of the template system includes a template 1 and transverse side reinforcement 2 set on the top of the template 1. The transverse side reinforcement 2 is located on the outside of the template 1 (the side away from the concrete to be poured), and multiple connecting holes 21 are arranged side by side along the length of the transverse side reinforcement 2 (see reference). Figure 4 The connecting hole 21 is used to fix the adjustable receiving system.

[0032] The adjustable receiving system is located inside template 1 (on the side closest to the concrete to be poured), see reference. Figure 1 The adjustable receiving system includes a pad 3, a fixing rod 4, a connecting rod 5, and an adjusting receiving component 6. The pad 3 is made of steel plate and is located on top of the transverse side reinforcement 2. Multiple pads 3 are arranged side by side along the length of the transverse side reinforcement 2 (the spacing between two adjacent pads 3 is, for example, 3m). A first strip hole 31 and a circular hole 32 are respectively opened at the first and second ends near the pad 3 (see reference). Figure 5 The first and second ends of the pad 3 are opposite each other. The first strip hole 31 and the circular hole 32 are used to connect the connecting rod 5 and the fixing rod 4 respectively (the first strip hole 31 and the circular hole 32 can also be used to connect the fixing rod 4 and the connecting rod 5 respectively).

The first end of the connecting rod 5 is fixedly connected to the first straight edge 61 through the fixing hole. The first end face of the connecting rod 5 is located in the fixing hole. Adjusting the position of the connecting rod 5 in the first strip hole 31 (the position of the fixing rod 4 in the first strip hole 31 can also be adjusted, in which case the connecting rod 4 and the connecting rod 5 pass through the first strip hole 31 and the circular hole 32 respectively) makes the second straight edge 62 of the adjusting receiving component 6 tightly attached to the inner side of the template 1; Reference Figure 8 A sliding groove 63 is provided between two adjacent connecting rods 5 on the first straight edge 61. The sliding groove 63 is formed by the inward indentation from the top to the bottom of the first straight edge 61 (when a fixing hole is provided on the first straight edge 61, in order to ensure the reliability of the connection between the connecting rod 5 and the first straight edge 61, the depth of the fixing hole is preferably greater than the depth of the sliding groove 63). The two ends of the sliding groove 63 are far apart from each other and extend to the connecting rod 5. When the rotating receiving system moves along the length direction of the adjusting receiving component 6, the sliding groove 63 is used to provide a moving track.

[0033] In one preferred embodiment, a first strip-shaped hole 31 and a second strip-shaped hole 33 are respectively provided near the first end and the second end of the pad 3 (see reference). Figure 6 The first strip hole 31 and the second strip hole 33 are used to connect the connecting rod 5 and the fixing rod 4 respectively (the first strip hole 31 and the second strip hole 33 can also be used to connect the fixing rod 4 and the connecting rod 5 respectively). Adjust the position of the connecting rod 5 in the first strip hole 31 and / or adjust the position of the fixing rod 4 in the second strip hole 33 (the position of the connecting rod 5 in the second strip hole 33 and / or adjust the position of the fixing rod 4 in the first strip hole 31 can also be adjusted, at which time the fixing rod 4 and the connecting rod 5 pass through the first strip hole 31 and the second strip hole 33 respectively), so that the adjusting receiving part 6 is tightly attached to the inner side of the template 1 on the second straight edge 62.

[0034] refer to Figure 2 and Figure 3 Each set of the rotating storage system includes a rotating storage component 9, a reference bar 10, a rotating connecting rod 11, and a diagonal brace 12. The rotating storage component 9 is made of angle steel (such as #3 angle steel, and the length of the rotating storage component 9 is 0.8-1.2m). The rotating storage component 9 is mounted on the first straight edge 61 of the adjusting storage component 6 via the rotating connecting rod 11 and is rotatably connected to the first straight edge 61. The rotating storage component 9 includes a first rotating edge 91 and a second rotating edge 92 that are perpendicular to each other. The first rotating edge 91 is horizontally mounted on the first straight edge 61, and a through hole is provided at the first end near the first rotating edge 91 for fixing the rotating connecting rod 11. Figure 2 and Figure 7The reference strip 10 is arranged along the length of the first rotating edge 91 and is located on the side of the first rotating edge 91 away from the second rotating edge 92. The reference strip 10 extends from the second end of the first rotating edge 91 to the first end. The first end and the second end of the first rotating edge 91 are opposite each other and correspond to the first end and the second end of the rotating receiving component 9, respectively. The bottom of the reference strip 10 is flush with the bottom of the first straight edge 61 of the adjusting receiving component 6. The rotating connecting rod 11 is arranged vertically. The first end of the rotating connecting rod 11 passes through the through hole on the first rotating edge 91 and extends into the sliding groove 63 of the first straight edge 61, and is stably connected to the first straight edge 61. The rotating connecting rod 11 is connected to the first rotating edge 92. A rotating edge 91 is fixedly connected. The rotating connecting rod 11 can be rotatably connected to the first straight edge 61 at both ends of the sliding groove 63. The second end of the rotating connecting rod 11 has a groove formed by the second end of the rotating connecting rod 11 being recessed inward towards the first end. The first end of the diagonal brace 12 is fixedly connected to the rotating connecting rod 11 and is close to the second end of the rotating connecting rod 11.

The second end of the diagonal brace 12 is fixedly connected to the first rotating edge 91 of the rotating receiving component 9 and is close to the second end of the first rotating edge 91. The diagonal brace 12 is used to improve the structural stability of the rotating receiving system.

[0035] In practical application, when the rotating receiving system is not in use, the entire rotating receiving component 9 is located on the first straight edge 61 of the adjusting receiving component 6. At this time, the reference strip 10 is attached to the first straight edge 61 and is located on the side of the first straight edge 61 away from the second straight edge 62. When the rotating receiving system is in use, the rotating connecting rod 11 is rotated so that the rotating receiving component 9 rotates to a state perpendicular to the adjusting receiving component 6 under the action of the rotating connecting rod 1. A push rod is then placed in the slot of the corresponding rotating connecting rod 11 on both sides of the concrete to be poured (the push rod can be made of channel steel). Simultaneously, the push rod is pushed to make reciprocating motion at both ends. Under the action of the push rod, the reference strip 10 on the rotating receiving part 9 can achieve the function of smoothing the concrete surface, thereby achieving the effect of receiving. After the rotating receiving system is used up, the push rod is removed and the rotating connecting rod 11 is rotated so that the rotating receiving part 9 rotates to a state parallel to the adjusting receiving part 6 under the action of the rotating connecting rod 1. At this time, the entire rotating receiving part 9 is located on the first straight edge 61 of the adjusting receiving part 6, and the reference strip 10 is attached to the side of the first straight edge 61 away from the second straight edge 62, and the receiving is completed. Example 2

[0036] This embodiment illustrates another structural form of the concrete placement elevation control device, see reference. Figure 9 and Figure 10The difference between this embodiment and embodiment 1 is that multiple first measuring scales 13 are arranged side by side along the length of the second rotating edge 92 of the rotating receiving component 9. When the second straight edge 62 of the adjusting receiving component 6 cannot be tightly attached to the inner side of the template 1, multiple second measuring scales 14 are arranged side by side along the length of the second straight edge 62. The first measuring scales 13 and the second measuring scales 14 are used to observe whether the concrete surface is flat. The first measuring scales 13 and the second measuring scales 14 have the same structure, and both the first measuring scales 13 and the second measuring scales 14 are provided with strip-shaped fixing holes; along The second rotating edge 92 has a plurality of fixed circular holes arranged side by side along its length, and the second straight edge 62 has a plurality of fixed circular holes arranged side by side along its length. Each first measuring scale 13 is fixedly connected to the second rotating edge 92 by a first bolt 15, which passes through the fixed circular holes on the second rotating edge 92 and the strip-shaped fixing hole on the first measuring scale 13. Each second measuring scale 14 is fixedly connected to the second straight edge 62 by a second bolt 16, which passes through the fixed circular holes on the second straight edge 62 and the strip-shaped fixing hole on the second measuring scale 14.
