Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and in particular to a device for verifying the position of reinforcing bars. Background Technology

[0002] With the development of science and technology and the promotion of green building concepts, more and more prefabricated buildings are being widely used in the construction of subways, stations and houses. However, in the current prefabricated construction, when the lower layer is a cast-in-place column and the upper layer is a precast column, the connection node between the cast-in-place column and the precast column is a key and difficult point. The current conventional practice is: at the column connection node, according to the design drawings of the upper precast column, the line is laid out and positioned, and then the dowel bars are reserved in the cast-in-place column. During the pouring process, spacers are used for positioning and the position of each steel bar is manually checked.

[0003] Traditional methods involve manual verification, which is arduous and inefficient. Although existing technologies have developed location verification devices, they are all customized for specific projects. In practice, the location of pre-embedded steel bars is complex and varied, resulting in poor versatility of existing rebar location verification devices. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a rebar position verification device, which solves the problem of poor versatility of the rebar position verification device in the prior art.

[0005] According to an embodiment of the present invention, a rebar position verification device includes a positioning plate, a detection cylinder, and a locking mechanism, wherein...

[0006] The positioning plate is provided with multiple horizontally extending grooves and each groove is vertically connected. Each groove is connected to the other by a longitudinal groove. Horizontal and vertical scales are respectively fixed on the grooves and the longitudinal groove.

[0007] Multiple detection cylinders are provided, and each detection cylinder can slide along the transverse groove or the longitudinal groove. Each detection cylinder is vertically connected and its inner diameter matches the outer diameter of the insert rib.

[0008] The locking mechanism is provided in multiple ways and is installed on each of the detection cylinders. Each locking mechanism is connected to the positioning plate to lock each of the detection cylinders on the positioning plate.

[0009] Compared with existing technologies, this invention has the following advantages: Since each detection cylinder can slide along the transverse and longitudinal grooves and its position on the positioning plate can be adjusted by a scale, and after proper adjustment, each detection cylinder can be locked by a locking mechanism, in practice, each detection cylinder can be adjusted to the position marked on the drawing according to different working conditions. At this time, the entire positioning plate is pressed on the rebar to be detected, and the rebar with the correct size and position will be inserted into the detection cylinder and pass upward. Therefore, workers can directly identify which rebars are in the wrong position by visual inspection and mark them on the positioning plate. It can be seen that this rebar position verification device greatly improves the versatility of the device. Attached Figure Description

[0014] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] This invention proposes an embodiment, such as... Figure 1 and Figure 2 As shown, a rebar position verification device includes a positioning plate 1, a detection cylinder 5, and a locking mechanism, wherein...

[0016] The positioning plate 1 is provided with multiple horizontally extending horizontal grooves 2, and each horizontal groove 2 is vertically connected. Each horizontal groove 2 is connected to the other by a vertical groove 3. In this embodiment, the vertical groove 3 is set in the middle of the positioning plate 1, and one end of the vertical groove 3 is set as an open shape so that each detection cylinder 5 can slide in or out. Horizontal and vertical scales 4 are respectively fixed on the horizontal grooves 2 and the vertical grooves 3. In the accompanying drawings, only the horizontal scale 4 is shown. The vertical scale 4 can be vertically fixed on the edge of the vertical groove 3 or the positioning plate 1. The scale 4 is used to indicate the specific position of the detection cylinder 5.

[0017] Multiple detection cylinders 5 are provided. Each detection cylinder 5 can slide along the transverse groove 2 or the longitudinal groove 3. Each detection cylinder 5 is vertically connected and its inner diameter matches the outer diameter of the insert bar.

[0018] Multiple locking mechanisms are provided and installed on each detection cylinder 5. Each locking mechanism is connected to the positioning plate 1 to lock each detection cylinder 5 onto the positioning plate 1. To illustrate the above structure more clearly, this embodiment takes one of the detection cylinders 5 as an example.

[0019] Using the above scheme, since each detection cylinder 5 can slide along the transverse groove 2 and longitudinal groove 3 and its position on the positioning plate 1 can be adjusted by the scale 4, and after proper adjustment, each detection cylinder 5 can be locked by the locking mechanism. In practice, each detection cylinder 5 can be adjusted to the position marked on the drawing according to different working conditions. At this time, the entire positioning plate 1 is pressed on the rebar to be tested. The rebar with the correct size and position will be inserted into the detection cylinder 5 and pass upward. Therefore, workers can directly identify which rebars are in the wrong position by visual inspection and mark them on the positioning plate 1. It can be seen that this rebar position verification device greatly improves the versatility of the device.

[0020] Furthermore, considering that the positioning plate 1 should be horizontal in practice, a level is installed on the positioning plate 1 to facilitate its position adjustment. The level can be any existing bubble level.

[0021] In another embodiment of the present invention, the main difference from the above embodiment is that a specific implementation of the detection cylinder 5 is proposed. The detection cylinder 5 includes an inner cylinder 502 and an outer cylinder 501. The outer wall of the outer cylinder 501 is in contact with the inner wall of any transverse groove 2 and the two can rotate relative to each other. The inner cylinder 502 is sleeved inside the outer cylinder 501 and the two are detachably fixed together. It also includes a limiting component, which is connected to the outer cylinder 501 and the positioning plate 1 to limit the axial movement of the outer cylinder 501. In this way, the inner cylinder 502 can be detached from the outer cylinder 501, and steel bars of different diameters can be detected by replacing the inner cylinder 502 with one of different inner diameters.

[0022] In another embodiment of the present invention, the main difference from the above embodiment lies in the specific implementation of the limiting component, which includes a first disc 6, a locking strip 7, and a stop strip 8, wherein...

[0023] The two ends of the baffle 8 are fixed on the positioning plate 1, and a gap is left between the middle part and the positioning plate 1 to form a cavity;

[0024] The snap-fit ​​strip 7 is fixed on the outer cylinder 501 or the first disc 6. In this embodiment, the snap-fit ​​strip 7 is fixed on the circumferential side of the first disc 6 as an example.

[0025] The first disc 6 is sleeved and fixed outside the outer cylinder 501. The first disc 6 can rotate to drive the snap-fit ​​strip 7 to insert or withdraw from the cavity. When the outer cylinder 501 slides along the transverse groove 2, the first disc 6 restricts the outer cylinder 501 from moving downward. When the free end of the snap-fit ​​strip 7 rotates between the stop strip 8 and the positioning plate 1, the snap-fit ​​strip 7 plays an auxiliary role in restricting the outer cylinder 501 from moving downward, and on the other hand, it prevents the outer cylinder 501 from moving upward.

[0026] In another embodiment of the present invention, the main difference from the above embodiment is that a different implementation of the locking mechanism is proposed. Specifically, the locking mechanism includes a first magnetic strip 9 and a second magnetic strip (in the accompanying drawings of this embodiment, the second magnetic strip and the snap-fit ​​strip 7 are integrally formed). The first magnetic strip 9 has multiple scales 4 that are perpendicular to the horizontal direction. The second magnetic strip is fixed on the snap-fit ​​strip 7 and magnetically attracted to the first magnetic strip 9. Thus, when the inner cylinder 502 and the outer cylinder 501 slide along the horizontal groove 2, the two second magnetic strips are parallel to the horizontal groove 2. When locking is required, rotating the outer cylinder 501 will drive the two second magnetic strips to rotate until they are attracted to the first magnetic strip 9, thereby locking the outer cylinder 501 in the horizontal groove 2. It should be understood that the spacing between the first magnetic strips 9 should be set reasonably. On the one hand, it can be set according to the common steel bar distribution spacing in practice to ensure the applicability of the device. On the other hand, the spacing between adjacent first magnetic strips 9 should be able to ensure that the second magnetic strip can rotate smoothly into the cavity. In addition, when the first magnetic strip 9 and the second magnetic strip are in contact, the second magnetic strip acts as a pointer.

[0027] Furthermore, there are two of each snap-fit ​​strip 7 and first magnetic strip 9. Each snap-fit ​​strip 7 and each magnetic strip are distributed in pairs on both sides of the outer cylinder 501 or the first disc 6. It should be noted that the two snap-fit ​​strips 7 are not symmetrically distributed, but are distributed on the left and right sides of the longitudinal axis of the outer cylinder 501. This arrangement is to ensure that the snap-fit ​​strips 7 on both sides can smoothly fit with each first magnetic strip 9 when the outer cylinder 501 is rotated.

[0028] In another embodiment of the present invention, the top of the outer cylinder 501 is higher than the first disc 6, and the upper and lower ends of the inner cylinder 502 are respectively fixed with a second disc 10 and a third disc (not shown in the figure). The second disc 10 is sleeved and fixed at the top of the inner cylinder 502, and the third disc is detachably fixed to the bottom of the inner cylinder 502 by bolts. The inner cylinder 502 and the outer cylinder 501 are keyed together. The second disc 10 and the third disc serve to restrict the axial movement of the inner cylinder 502. On the other hand, a space is formed between the second disc 10 and the first disc 6, which is convenient for workers to insert their fingertips, so that the outer cylinder 501 and the inner cylinder 502 can be rotated easily.

[0029] Furthermore, the bottom end of the inner cylinder 502 extends through the outer cylinder 501, which allows the bottom end of the inner cylinder 502 to be more clearly fitted onto the reinforcing bars.

[0030] In another embodiment of the present invention, the main difference from the above embodiments lies in the provision of another specific implementation method of the locking mechanism, such as... Figure 3 As shown, the detection cylinder 5 has an external thread, and the locking mechanism includes a nut 11. The nut 11 is sleeved on the outside of the detection cylinder 5 and the two are threaded together. The end face of the nut 11 is pressed against the positioning plate 1 to complete the locking. In practice, an anti-slip rubber pad can also be set between the nut 11 and the positioning plate 1 to make the locking of the detection cylinder 5 more stable. However, this locking method is obviously not as convenient as the other locking method mentioned above. A pointer can also be fixed on the detection cylinder 5 to facilitate workers to read the reading of the scale 4.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
