Therefore, it is urgent to improve the detection equipment and methods, and design a steel bar strength detection device for construction engineering to improve safety and reduce the potential harm to personnel caused by debris flying. Summary of the Utility Model
[0004] In order to overcome the shortcomings of the currently adopted steel bar strength detection devices and methods, where the pressure applied during the process may cause the steel bar to break and debris to fly, the technical problem to be solved is: to provide a steel bar strength detection device for construction engineering.

Detailed Embodiment
[0018] The present utility model will be specifically described below with reference to the drawings.
[0019] Embodiment: A steel bar strength detection device for construction engineering, as Figures 1 - 5 shown, includes a mounting base 1, a pressure gauge 2, a display screen 3, a slide rail 4, a placement rack 5, a hydraulic press 7, a limit block 81, a screw rod 9, a protective shell 12, a guide rod 13, a covering cover 14 and a second handle 15. The pressure gauge 2 is embedded in the middle of the mounting base 1. The pressure gauge 2 is connected to the display screen 3 through a circuit. The display screen 3 is installed on the front side of the mounting base 1. The hydraulic press 7 is fixedly installed at the rear side of the top of the mounting base 1 through a support frame. The pressing head of the hydraulic press 7 is located directly above the pressure gauge 2. Slide rails 4 are symmetrically arranged on the left and right sides of the top of the mounting base 1. A placement rack 5 is slidably connected to the slide rails 4. Guide sleeves are provided at both the left and right ends of the upper part of the placement rack 5. Round rods 8 are slidably arranged in the guide sleeves. Limit blocks 81 are provided at the ends of the round rods 8. The bottom of the limit block 81 cooperates with the vertical block at the rear side of the placement rack 5 to clamp and fix steel bars of different sizes. A cross bar 82 is fixedly connected between the middle parts of the two round rods 8. An internal threaded hole is opened in the middle of the front side of the placement rack 5. A screw rod 9 is screwed onto the internal threaded hole on the front side of the placement rack 5. The screw rod 9 is rotatably connected to the middle part of the cross bar 82. A protective shell 12 is provided at the top of the mounting base 1. Guide rods 13 are provided at the front side of the top of the protective shell 12 and the front side of the top of the mounting base 1. Covering covers 14 are symmetrically slidably arranged on the guide rods 13. Second handles 15 are symmetrically provided on the front sides of the two covering covers 14. When detecting the strength of a steel bar, by turning the screw rod 9, the cross bar 82 is driven to move outward along the screw rod 9. Because the cross bar 82, the round rod 8 and the limit block 81 are connected as a whole, finally the limit block 81 slides outward along the surface of the placement rack 5. Then the steel bar is placed into the groove formed by the limit block 81 and the placement rack 5. By turning the screw rod 9 in the opposite direction, the limit block 81 slides in the opposite direction until the limit block 81 clamps the steel bar with the placement rack 5, then stop turning the screw rod 9. The design of the limit block 81 and other devices enables steel bars of different sizes to be fixed, and the limit block 81 is integrally long strip-shaped, effectively preventing the steel bar from flying off when it is bent to a certain extent during detection. After the steel bar is fixed, by starting the hydraulic press 7, the hydraulic press 7 slowly descends to press the steel bar onto the surface of the pressure gauge 2. The pressure gauge 2 transmits the detected pressure value to the display screen 3 through a circuit for display. Pull the second handle 15 to close the two covering covers 14 along the guide rods 13 towards the middle. When the hydraulic press 7 presses down until the steel bar is about to break, the protective shell 12 and the covering cover 14 on the mounting base 1 will effectively ensure the safety of the detection personnel.
[0020] As Figure 2As shown in the figure, it further includes a limit frame 10 and a clamping rod 11. The clamping rod 11 is provided at the bottom of the front side of the placement rack 5, and the limit frame 10 is provided at the front side of the top of the mounting seat 1. The clamping rod 11 is located at the middle position of the limit frame 10. The middle part of the clamping rod 11 and the limit frame 10 are both penetrated and interlocked by the stud on the limit frame 10. Before the steel bar strength test, it is necessary to place the steel bar first. Slide the placement rack 5 forward along the slide rail 4 by pulling out the stud. After placing and fixing the steel bar, reset the placement rack 5 and reinsert the stud to fix the placement rack 5 to prevent the placement rack 5 from moving along the slide rail 4 during the test.
[0021] As Figure 5 shown in the figure, it further includes a lighting lamp 18. Two lighting lamps 18 are symmetrically arranged at the top of the rear panel inside the protective shell 12. When performing the steel bar strength test, it is necessary to first place the steel bar into the placement rack 5 and fix it through the limit block 81. Since the light inside the protective shell 12 is weak, using the lighting lamp 18 can complete these actions more quickly and accurately.
[0022] As Figure 3 and Figure 4 shown in the figure, it further includes a locking shaft 16 and a lock catch 17. The locking shaft 16 is provided on the right side of the left covering cover 14, and the lock catch 17 is provided on the left side of the right covering cover 14. After sliding the two covering covers 14 along the guide rod 13 to the middle and closing them tightly through the second handle 15, rotate the lock catch 17 counterclockwise by a certain angle to fasten the locking shaft 16, further strengthening the covering cover 14 and the protective shell 12, and further ensuring the safety of the testing personnel in case of an accident during the steel bar strength test.
[0023] As Figures 3 - 5 shown in the figure, the side of the covering cover 14 opposite to the sliding direction is designed as an arc. A rectangular opening is provided in the middle of the covering cover 14, and a rectangular grille is provided in the rectangular opening. When performing the steel bar strength test, the internal test situation can be observed through the rectangular grille. If it is found that the steel bar breaks and debris splashes, the test process can be paused in time. The arc design of the side of the covering cover 14 opposite to the sliding direction makes the covering cover 14 fit the protective shell 12 more closely.
[0024] As Figure 2 and Figure 4 shown in the figure, it further includes a first handle 6. The first handle 6 is provided on both the left and right sides of the top plate of the mounting seat 1. Through the first handle 6, the entire steel bar strength testing equipment can be carried, and it can be carried to places where some large testing equipment cannot reach, realizing portable and flexible testing.
[0025] Those skilled in the art of this industry should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
