Description

Technical Field

[0001] The utility model relates to the technical field of steel bar measuring tools, in particular to an auxiliary frame for measuring the length of steel bars. Background Technique

[0002] Steel bars are commonly used in steel bars for reinforced concrete and prestressed reinforced concrete. Their cross-sections are usually circular, and they include various types such as plain round steel bars and ribbed steel bars. Steel bars play a crucial role in building structures. Currently, relevant technical standards in implementation require measuring the weight of steel bars during inspection. The current inspection method is to first manually measure the length of the steel bar, then weigh it, and then calculate the weight of the steel bar through a formula. Therefore, the measurement of the length of the steel bar plays a crucial role in the accuracy of the test results.

[0003] Currently, the common method for measuring the length of steel bars is to place the steel bar on the operating table and directly measure its actual length with a steel tape measure. When measuring, one person needs to fix the steel bar, and another person uses the steel tape measure for measurement. This method increases the number of inspectors when measuring a large number of steel bar samples, reduces the measurement efficiency and accuracy, and may also result in large deviations.

[0004] Therefore, it is necessary to provide an auxiliary frame for measuring the length of steel bars to solve the above technical problems. Content of the Utility Model

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an auxiliary frame for measuring the length of steel bars to solve the current common method for measuring the length of steel bars, which is to place the steel bar on the operating table and directly measure its actual length with a steel tape measure. When measuring, one person needs to fix the steel bar, and another person uses the steel tape measure for measurement. This method increases the number of inspectors when measuring a large number of steel bar samples, reduces the measurement efficiency and accuracy, and may also result in large deviations.

[0006] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] An auxiliary frame for measuring the length of steel bars, comprising: a support frame;

[0008] The overall shape of the support frame is a U-shaped structure, and its inner top surface is bolted and connected to the right top surface of the measuring mechanism. An operating mechanism is installed on the left side of the measuring mechanism. The inner length of the measuring mechanism is set to a standard size, and the value of the standard size is consistent with the reference length of the steel bar.

[0009] In one embodiment, the measuring mechanism is composed of a fixing plate, an auxiliary plate, through holes, slots, connection grooves, and a measuring ruler. The fixing plate is of a rectangular structure as a whole. Its left side is integrally provided with the auxiliary plate. The auxiliary plate is of an L-shaped structure arranged horizontally as a whole. The short side of the auxiliary plate is connected to the fixing plate. The other end of the auxiliary plate and the fixing plate is open. Through holes are arranged at intervals on the long side section of the auxiliary plate. A slot is opened at the lower part of the left side surface of the fixing plate. A connection groove is opened in the middle of the end surface of the fixing plate that is open. A measuring ruler is arranged inside the connection groove, and a tension spring is installed at the connection between the two.

[0010] In one embodiment, the operating mechanism is composed of a positioning table, an arc convex surface, a bottom plate, a connecting rod, a pulling plate, a positioning groove, and a spring telescopic rod. The positioning table is located between the fixing plate and the auxiliary plate. The surface of the positioning table facing the fixing plate is an arc convex surface. The bottom of the arc convex surface is provided with a bottom plate. The bottom plate is arranged corresponding to the slot, and their sizes are the same. Both sides of the left side surface of the positioning table are connected to the pulling plate through connecting rods. The connecting rods penetrate through the through holes. A handle is installed on the left side surface of the pulling plate. A positioning groove is opened in the middle of the left side surface of the positioning table. The telescopic end of the spring telescopic rod is installed and connected to the inner wall of the positioning groove, and the other end of the spring telescopic rod is installed and connected to the wall surface of the auxiliary plate.

[0011] In one embodiment, a baffle is installed at the end of the extending end of the measuring ruler. The baffle and the measuring ruler are of an L-shaped structure as a whole.

[0012] In one embodiment, the support frame is installed and connected to the buffer mechanism. A placement rack is temporarily placed below the auxiliary plate and the fixing plate. Moving wheels are installed at the bottom of the placement rack. The buffer mechanism is composed of a mounting plate, a connecting frame, a buffer plate, and a buffer pad. The installation height of the mounting plate is below the top opening of the placement rack. A connecting frame is installed on the side surface of the mounting plate facing the placement rack. The buffer plate is hinged to the connecting frame, and a torsion spring is installed at the hinge. The extending section of the buffer plate extends to the middle inside the placement rack. A buffer pad is bonded to the top surface of the buffer plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) The utility model positions the steel bar by placing it between the auxiliary plate and the fixed plate, making the bottom of the steel bar abut against the top surface of the bottom plate and the end of the steel bar abut against the short side of the auxiliary plate. Due to the arrangement of the spring telescopic rod, the arc convex surface continuously extrudes the steel bar. If the steel bar extends beyond the open notch of the fixed plate and the auxiliary plate, by pulling the measuring ruler, making the end of the measuring ruler flush with the extended end of the steel bar, the length of the steel bar outside the calibrated size can be obtained. Adding the two lengths can complete the accurate dimension measurement. After the measurement is completed, by pulling the pull plate, the positioning table retreats towards the auxiliary plate under the action of the spring telescopic rod, causing the bottom plate to disengage from the slot, and the steel bar drops after losing the limit.

[0015] (2) After the steel bar measurement is completed by the utility model, it falls inside the placement rack. After contacting the buffer plate, the torsion spring at the hinged end of the buffer plate dissipates the force, reducing the impact collision between the steel bar and the placement rack. After the placement racks are stacked, they are removed and placed into another set of placement racks to complete the storage after the steel bar measurement, reducing the workload of manual labor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the utility model in conjunction with the drawings and embodiments. The implementation manners of the utility model include but are not limited to the following embodiments.

[0022] As Figure 1 - Figure 2 shown, the steel bar length measurement auxiliary rack provided by the utility model includes: support frame 1, measurement mechanism 2, operation mechanism 3, placement rack 4, buffer mechanism 5;

[0023] As Figure 1 - Figure 2As shown, the support frame 1 is integrally U-shaped. Its inner top surface is bolted to the right top surface of the measuring mechanism 2. An operating mechanism 3 is installed on the left side of the measuring mechanism 2. The operating mechanism 3 is used to support the steel bar and cancel the support after the steel bar is measured. The inner length of the measuring mechanism 2 is set to a standard size, and the value of the standard size is consistent with the reference length of the steel bar. For example, if the required length of the steel bar at the construction site is 50 cm, the inner length of the measuring mechanism 2 is also 50 cm. After placing the steel bar in the measuring mechanism 2, only the part of the steel bar that extends beyond the measuring mechanism 2 needs to be measured and added to the fixed length of 50 cm to obtain the length of the steel bar, reducing the operation steps of manually pulling the tape measure and positioning the end of the steel bar.

[0024] Preferably, in one embodiment, as Figure 3 shown, the measuring mechanism 2 is composed of a fixing plate 21, an auxiliary plate 22, through holes 23, slots 24, connection grooves 25, and a measuring ruler 26. The fixing plate 21 is integrally rectangular. Its left side is integrally provided with the auxiliary plate 22. The auxiliary plate 22 is integrally L-shaped and horizontally arranged. The short side of the auxiliary plate 22 is connected to the fixing plate 21. The other end of the auxiliary plate 22 and the fixing plate 21 is open. Through holes 23 are spacedly arranged on the long side section of the auxiliary plate 22. A slot 24 is opened at the lower part of the left side surface of the fixing plate 24. A connection groove 25 is opened in the middle of the open end surface of the fixing plate 21. A measuring ruler 26 is arranged inside the connection groove 25, and a tension spring is installed at the connection part between the two.

[0025] Preferably, in one embodiment, as Figure 3As shown in the figure, the operating mechanism 3 is composed of a positioning table 31, an arc convex surface 32, a bottom plate 33, a connecting rod 34, a pulling plate 35, a positioning groove 36, and a spring telescopic rod 37. The positioning table 31 is located between the fixing plate 21 and the auxiliary plate 22. The surface of the positioning table 31 facing the fixing plate 21 is an arc convex surface 32. The bottom of the arc convex surface 32 is provided with a bottom plate 33. The bottom plate 33 is correspondingly arranged with the slot 24, and their sizes are the same. The two sides of the left side surface of the positioning table 31 are connected to the pulling plate 35 through the connecting rod 34. The connecting rod 34 penetrates through the through hole 23. A handle is installed on the left side surface of the pulling plate 35. A positioning groove 36 is opened in the middle of the left side surface of the positioning table 31. The inner wall of the positioning groove 36 is installed and connected to the telescopic end of the spring telescopic rod 37. The other end of the spring telescopic rod 37 is installed and connected to the wall surface of the auxiliary plate 22. During operation, by placing the steel bar between the auxiliary plate 22 and the fixing plate 21, the bottom of the steel bar abuts against the top surface of the bottom plate 33, and the end of the steel bar abuts against the short side of the auxiliary plate 22 to complete the positioning. Due to the setting of the spring telescopic rod 37, the arc convex surface 32 continuously presses the steel bar. If the steel bar extends beyond the open notch of the fixing plate 21 and the auxiliary plate 22, by pulling the measuring ruler 26, the end of the measuring ruler 26 is level with the extended end of the steel bar, and the length of the steel bar outside the calibrated size can be obtained. The sum of the two can complete the accurate size measurement. After the measurement is completed, by pulling the pulling plate 35, the positioning table 31 retreats towards the auxiliary plate 22 under the action of the spring telescopic rod 37, so that the bottom plate 33 disengages from the slot 24, and the steel bar falls after losing the limit.

[0026] Preferably, in one embodiment, as Figure 3 shown, a baffle 27 is installed at the end of the extended end of the measuring ruler 26. The baffle 27 and the measuring ruler 26 are integrally in an L-shaped structure. Through the setting of the baffle 27, when measuring the extended part of the steel bar, the baffle 27 abuts against the end of the steel bar to provide an auxiliary positioning effect and make the measurement result more accurate.

[0027] Preferably, in one embodiment, as Figure 1 、 Figure 4As shown, the support frame 1 is installed and connected to the buffer mechanism 5. A placement rack 4 is temporarily placed below the auxiliary plate 22 and the fixed plate 21. Movable wheels are installed at the bottom of the placement rack 4. The buffer mechanism 5 is composed of a mounting plate 51, a connecting frame 52, a buffer plate 53, and a buffer pad 54. The installation height of the mounting plate 51 is below the top opening of the placement rack 4. A connecting frame 52 is installed on the side of the mounting plate 51 facing the placement rack 4. The buffer plate 53 is hinged to the connecting frame 52, and a torsion spring is installed at the hinge. The extending section of the buffer plate 53 extends to the middle inside the placement rack 4. A buffer pad 54 is adhesively bonded to the top surface of the buffer plate 53. During operation, after the steel bar measurement is completed, it falls into the placement rack 4. After contacting the buffer plate 53, the torsion spring at the hinged end of the buffer plate 53 is used to relieve the force, reducing the impact collision between the steel bar and the placement rack 4. After the placement rack 4 is stacked, it is removed and another set of placement racks 4 is placed, completing the storage after the steel bar measurement and reducing the workload of manual labor.

[0028] The working principle of the present utility model:

[0029] During operation, by placing the steel bar between the auxiliary plate 22 and the fixed plate 21, the bottom of the steel bar abuts against the top surface of the bottom plate 33, and the end of the steel bar abuts against the short side of the auxiliary plate 22 to complete positioning. Due to the setting of the spring telescopic rod 37, the arc convex surface 32 continuously presses the steel bar. If the steel bar extends beyond the open notch of the fixed plate 21 and the auxiliary plate 22, by pulling the measuring ruler 26, the end of the measuring ruler 26 is made to be level with the extended end of the steel bar, and the length of the steel bar outside the calibrated size can be obtained. Adding the two can complete the accurate size measurement. After the measurement is completed, by pulling the pull plate 35, the positioning table 31 retracts towards the auxiliary plate 22 under the action of the spring telescopic rod 37, causing the bottom plate 33 to disengage from the slot 24. After the steel bar loses its limit, it falls. After the steel bar measurement is completed, it falls into the placement rack 4. After contacting the buffer plate 53, the torsion spring at the hinged end of the buffer plate 53 is used to relieve the force, reducing the impact collision between the steel bar and the placement rack 4. After the placement rack 4 is stacked, it is removed and another set of placement racks 4 is placed, completing the storage after the steel bar measurement and reducing the workload of manual labor.

[0030] The above embodiments are only one of the preferred embodiments of the present utility model and should not be used to limit the protection scope of the present utility model. Any meaningless modifications or polishings made on the main design concept and spirit of the present utility model, as long as the technical problems solved are still the same as those of the present utility model, should be included within the protection scope of the present utility model.
