Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a masonry flatness testing device for testing the quality of building construction. Background Technology

[0002] Compared to reinforced concrete structures, masonry saves on cement and steel, and does not require formwork or special technical equipment during construction, thus saving timber. The disadvantages of masonry structures are their heavy weight, large volume, and labor-intensive construction. Due to the weak bond between bricks, stones, blocks, and mortar, unreinforced masonry has very low tensile, flexural, and shear strengths. Its brittle nature, determined by its constituent materials and connection methods, makes it more susceptible to damage during earthquakes, resulting in poor seismic performance. Therefore, the seismic design of multi-story masonry structures requires the use of structural columns, ring beams, and other tie beams to improve their ductility and collapse resistance.

[0003] After masonry construction, the flatness of the outer surface of the masonry needs to be tested to determine whether it meets the acceptance standards. However, existing testing equipment has low efficiency, reducing testing speed and accuracy, and cannot obtain flatness data from multiple locations at once. Therefore, further improvements are needed. Summary of the Invention

A connecting plate is mounted on the upper end of the moving block, and a testing plate is vertically mounted on the upper end of the connecting plate. A testing mechanism is provided on the testing plate. A moving mechanism for changing the horizontal position of the testing mechanism is also provided on the upper end of the testing base.

For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1: See Figures 1 to 7 In this embodiment of the invention, a masonry flatness testing device for construction quality testing includes a testing base 1. A support frame 21 is symmetrically hinged inside the testing base 1. A support wheel 22 is rotatably mounted on the bottom of the support frame 21. A support mechanism for changing the position of the support wheel 22 is provided inside the testing base 1. A moving block 4 is slidably mounted on the upper end of the testing base 1 through a guide part. A connecting plate 7 is mounted on the upper end of the moving block 4. A testing plate 8 is vertically mounted on the upper end of the connecting plate 7. A testing mechanism is provided on the testing plate 8. A moving mechanism for changing the horizontal position of the testing mechanism is also provided on the upper end of the testing base 1.

[0022] The moving mechanism in this embodiment includes fixed plates 2 symmetrically mounted on both sides of the upper end of the detection base 1. A movable lead screw 3 is rotatably mounted between the fixed plates 2. The movable lead screw 3 is mounted on a movable block 4 via a threaded structure. One end of the movable lead screw 3 passes through the fixed plate 2 and is connected to a movable handle 5. By rotating the movable handle 5, the movable lead screw 3 is driven to rotate. Then, with the cooperation of the threaded structure, the movable block 4 drives the entire detection plate 8 to move horizontally, ultimately enabling the detection mechanism to perform a large-scale flatness detection.

[0023] In addition, the detection mechanism in this embodiment includes a magnetic plate 15 vertically fixed on the connecting plate 7, a writing paper 11 is provided on the magnetic plate 15 through a plurality of magnetic blocks 16, a plurality of scale lines 14 are provided on the writing paper 11, and the detection mechanism also includes a detection component.

[0024] The detection assembly includes multiple detection shafts 10 that are horizontally slidably mounted on the detection plate 8. One end of each detection shaft 10 is fixedly mounted with an abutment block 13. An abutment spring 12 is installed between the abutment block 13 and the detection plate 8 and is sleeved on the outside of the detection shaft 10. A writing pen 18 is detachably mounted on the side of the abutment block 13 that cooperates with the writing paper 11. The end of the abutment shaft away from the abutment block 13 abuts against the masonry.

[0025] Meanwhile, the detection plate 8 is provided with a detection hole 17 that cooperates with the detection shaft 10.

[0026] With the above setup, during testing, the clean writing paper 11 is first fixed on the magnetic plate 15 using the magnetic block 16. Then, one end of each of the multiple detection shafts 10 is brought into contact with the masonry to be tested under the pressure of the abutment spring 12. After that, the entire detection plate 8 is moved horizontally using the moving mechanism. At this time, the writing pen 18 continuously draws lines on the writing paper 11 under the action of the abutment block 13. When uneven masonry is required, the drawn straight line is longer, and vice versa. Then, the staff uses the scale line 14 to determine which horizontal position has the worst flatness and which horizontal position has the lowest flatness, thereby obtaining the flatness parameters of the masonry in a specific area.

[0027] In addition, in one embodiment, the support mechanism includes a support shaft 9 rotatably mounted between the bottom of the detection seat 1. One end of the support shaft 9 passes through the detection seat 1 and is connected to a support handle 23. The support shaft 9 is fitted with a support block 19 through a threaded portion. The support block 19 is mounted on the support frame 21 through a support portion.

[0028] The threaded part includes a threaded sleeve a24 at one end of the support shaft 9 and a threaded sleeve b25 at the other end, with the threads of the threaded sleeves a24 and b25 having opposite directions.

[0029] In addition, the support includes support columns 20 symmetrically fixed on the support block 19 and support grooves 26 provided on the support frame 21, with the support columns 20 slidably disposed inside the support grooves 26.

[0030] With the above settings, during testing, firstly, rotate the support handle 23 to make the support shaft 9 rotate. Then, under the action of the threaded part, ensure that the support frame 21 is unfolded and supported. At this time, the support wheel 22 will contact the ground to ensure the mobility of the entire testing device. After the testing device moves to the corresponding position, reverse the support handle 23 to make the support wheel 22 retract into the testing seat 1. At this time, the testing seat 1 will contact the ground to ensure the stability of the testing device during the testing process.

[0031] Example 2: In another embodiment of the present invention, the difference from the above embodiment is that the guide portion includes a guide groove 6 disposed on the upper surface of the detection seat 1, and a movable block 4 is slidably installed inside the guide groove 6. The guide groove 6 has a trapezoidal groove structure, and the bottom of the movable block 4 has a dovetail block structure. By setting the guide groove 6 and the movable block 4 into the above structure, the stability of the detection plate 8 during movement is effectively guaranteed, ultimately ensuring the accuracy of the detection mechanism in detecting the flatness of the masonry.

[0032] In summary, during the inspection, the entire inspection device is first moved to the area to be inspected using a support mechanism, while the ends of multiple inspection shafts 10 are placed against the masonry. Then, a moving mechanism is used to perform multi-position flatness inspections within a certain horizontal range. Afterward, the support mechanism is moved again to obtain flatness data for other areas. The above inspection process is simple, convenient, and quick.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
