Description

Technical Field

[0001] This utility model relates to the field of building inspection equipment technology, specifically to a flatness testing device for building engineering. Background Technology

[0002] In building construction, after concrete is poured, the flatness of the poured components needs to be inspected. Only after the inspection is passed can the next step of construction be carried out. The existing method for inspecting the flatness of concrete components is to use a steel ruler and a feeler gauge together. The steel ruler is placed close to the surface of the concrete component and rotated while the feeler gauge is inserted into the gap between the steel ruler and the surface of the concrete component for inspection.

[0003] However, this detection method has many drawbacks:

[0004] Firstly, during the operation, the staff needs to hold a steel ruler against the wall with one hand and operate a wedge gauge with the other. However, it is difficult to stabilize the steel ruler and accurately control the gauge to insert into the gap with one hand at the same time, which makes the inspection operation cumbersome and inefficient. It must be completed by two staff members, resulting in a waste of human resources.

[0005] Secondly, existing testing tools lack a reliable elastic clamping mechanism, and the feeler gauge cannot automatically and tightly fit the surface to be tested. During testing, it is necessary to press continuously by hand, which not only increases the operating burden, but also easily causes the feeler gauge to shift due to uneven pressing pressure or hand tremors, affecting the accuracy of the test results.

[0006] Third, during the testing process, the relative position adjustment of the steel ruler and feeler gauge is inconvenient, making it difficult to quickly locate different testing points. Furthermore, the lack of an effective locking device after adjustment makes it easy for the position to slip, further reducing testing efficiency and accuracy. Utility Model Content

[0007] The present invention aims to solve the problems mentioned in the background art by providing a flatness testing device for building engineering.

[0008] The specific technical solution is as follows:

[0009] A flatness testing device for building engineering includes a reference plate, a mounting base, and a wedge gauge. The wedge gauge is straight. Supports are fixed on both sides of the reference plate, and a mounting rod extending along the length of the reference plate is fixed between the two supports. A sliding seat is slidably fitted on the mounting rod, and a spring-loaded mechanism is provided on the side of the sliding seat. The mounting seat is installed on the side of the reference plate through the spring-loaded mechanism. A sliding rod is slidably inserted into a guide hole provided on the mounting seat. The wedge gauge is fixed to one end of the sliding rod, and a handle is installed at the other end of the sliding rod. The spring-loaded mechanism is used to press the wedge gauge firmly onto the surface to be tested.

[0010] Furthermore, the spring-loaded mechanism includes a cantilever, a guide rod, and a spring. The cantilever is fixed to the side of the sliding seat, and a through hole is provided on the cantilever. The guide rod is slidably installed through the through hole, and the mounting seat is fixed to the bottom end of the guide rod. The spring is sleeved on the guide rod, with one end of the spring fixed to the cantilever and the other end fixed to the top of the mounting seat.

[0011] Furthermore, the through hole and guide hole are square holes, and the guide rod and slide rod are square rods.

[0012] Furthermore, the sliding seat is provided with a fastening device for locking and limiting the sliding seat. The fastening device is a fastening bolt. The top of the sliding seat is provided with a threaded hole that extends vertically downward and communicates with the hole inside. The fastening bolt is screwed into the threaded hole in a matching threaded manner, and the bottom end of the fastening bolt abuts against the outer wall of the mounting rod.

[0013] Furthermore, the bottom surface of the sliding seat slides and fits into contact with the surface of the reference plate.

[0014] Furthermore, two L-shaped arms are fixed to one side of the reference plate, and a handle is fixed between the ends of the two L-shaped arms. The handle is fitted with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, through the connection of the spring-loaded mechanism mounting base and the guide hole, allows a wedge gauge to be installed on one side of a reference plate. The sliding cooperation between the sliding seat and the mounting rod ensures that the wedge gauge can be adjusted and moved along the length of the reference plate. The spring-loaded mechanism ensures that the contact surface of the wedge gauge is pressed firmly against the surface to be tested. The operator holds the reference plate with one hand, placing it against the surface to be tested, and uses the other hand to grasp the handle and push the sliding rod, allowing the wedge gauge to enter the gap between the reference plate and the wall surface, thus enabling flatness measurement. This allows for testing to be completed by a single person, saving manpower. Furthermore, the structure is simple, the operation is convenient, and the testing is more efficient.

[0017] This invention features a spring-loaded mechanism that allows the wedge gauge to be pressed tightly against the surface to be tested by the elastic force of the spring, improving testing accuracy. Simultaneously, the elasticity of the spring and the sliding action of the guide rod allow the wedge gauge to move adaptively according to the actual flatness of the wall surface, ensuring that the wedge gauge remains in contact with the wall surface at all times, eliminating the need for manual hand-holding and pressing.

[0018] This invention achieves a fastening effect on the sliding seat by tightening the fastening bolt, which presses against the mounting rod, ensuring that the wedge gauge does not shift arbitrarily. This helps the wedge gauge to remain in the position to be tested, making it convenient for workers to operate the wedge gauge with one hand. Furthermore, by pinching the end of the fastening bolt, it is easy to apply force to push and adjust the sliding seat, achieving two benefits in one. Attached Figure Description

In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more.

[0025] like Figures 1-4 As shown, this utility model provides a flatness testing device for building engineering, comprising:

[0026] The device includes a reference plate 1, a mounting base 4, and a wedge gauge 5. The wedge gauge 5 is straight. Supports 11 are fixed on both sides of the reference plate 1. A mounting rod 12 extending along the length of the reference plate 1 is fixed between the two supports 11. A sliding seat 2 is slidably mounted on the mounting rod 12. A spring-loaded mechanism 3 is provided on the side of the sliding seat 2. The mounting base 4 is mounted on the side of the reference plate 1 through the spring-loaded mechanism 3. A sliding rod 42 is slidably inserted into a guide hole 41 provided on the mounting base 4. The wedge gauge 5 is fixed to one end of the sliding rod 42. A handle 421 is installed on the other end of the sliding rod 42. The spring-loaded mechanism 3 is used to press the wedge gauge 5 against the surface to be tested.

[0027] When using this flatness measuring device to test the flatness of a building, the wedge gauge 5 is installed on one side of the reference plate 1 under the connection of the spring-loaded mechanism 3, the mounting base 4, and the guide hole 41. Under the sliding cooperation of the sliding seat 2 and the mounting rod 12, the wedge gauge 5 can be adjusted to move along the length of the reference plate 1. Under the spring-loaded action of the spring-loaded mechanism 3, the contact surface of the wedge gauge 5 can be pressed tightly onto the surface to be tested. The operator holds the reference plate 1 with one hand and places it against the surface to be tested, while the other hand pinches the handle 421 and pushes the sliding rod 42 to allow the wedge gauge 5 to enter the gap between the reference plate 1 and the wall surface, thus allowing the flatness measurement to be performed. This allows the testing work to be completed by a single person, saving manpower. The device is simple in structure, easy to operate, and more efficient in testing.

[0028] In addition, when it is necessary to measure different positions, by pushing the wedge gauge 5, the sliding seat 2 is driven to slide along the mounting rod 12 until the wedge gauge 5 reaches the required detection position. The stability of the wedge gauge 5 can be guaranteed throughout the entire operation process.

[0029] Specifically, the spring-pressing mechanism 3 includes a cantilever 31, a guide rod 32, and a spring 33. The cantilever 31 is fixed to the side of the sliding seat 2, and a through hole 311 is provided on the cantilever 31. The guide rod 32 is slidably installed through the through hole 311. The mounting seat 4 is fixed to the bottom end of the guide rod 32. The spring 33 is sleeved on the guide rod 32. One end of the spring 33 is fixed to the cantilever 31, and the other end is fixed to the top of the mounting seat 4. By setting the spring-pressing mechanism 3, the spring force of the spring 33 can push the wedge gauge 5 to fit tightly against the surface to be tested, improving the testing accuracy. At the same time, with the elasticity of the spring 33 and the sliding action of the guide rod 32, the wedge gauge 5 can adaptively move according to the actual flatness of the wall surface, ensuring that the wedge gauge 5 can always fit against the wall surface without manual hand-pressing.

[0030] Specifically, the through hole 311 and guide hole 41 are square holes, and the guide rod 32 and slide rod 42 are square rods. Designing the cross-sections of the through hole 311 and guide rod 32 to be mutually compatible square shapes can prevent the guide rod 32 from deflecting. Designing the cross-sections of the guide hole 41 and slide rod 42 to be mutually compatible square shapes can prevent the guide hole 41 from deflecting arbitrarily, thereby ensuring the accurate orientation of the wedge gauge 5.

[0031] Specifically, the sliding seat 2 is equipped with a fastening device for locking and limiting the sliding seat 2. The fastening device is a fastening bolt 23. The top of the sliding seat 2 is provided with a threaded hole 22 that extends vertically downward and communicates with the hole 21 inside. The fastening bolt 23 is screwed into the threaded hole 22 with matching threads. The bottom end of the fastening bolt 23 abuts against the outer wall of the mounting rod 12. When the sliding seat 2 is slid and adjusted to the desired position of the wedge gauge 5, the fastening bolt 23 is tightened. The fastening bolt 23 abuts against the mounting rod 12 to achieve a fastening effect on the sliding seat 2, ensuring that the wedge gauge 5 will not shift arbitrarily. This helps the wedge gauge 5 to be continuously maintained at the position to be tested, thus facilitating the operation of the wedge gauge 5 with one hand. Furthermore, by pinching the end of the fastening bolt 23, it is convenient to apply force to push and adjust the sliding seat 2. This achieves two goals at once. When it is necessary to slide and adjust the sliding seat 2 again, the fastening bolt 23 can be loosened.

[0032] Specifically, the bottom surface of the sliding seat 2 slides and fits against the surface of the reference plate 1, which can guide and limit the sliding seat 2, preventing the sliding seat 2 from deflecting and causing the wedge gauge 5 to become misaligned.

[0033] Specifically, two L-shaped arms 13 are fixed on one side of the reference plate 1, and a handle 14 is fixed between the ends of the two L-shaped arms 13. By holding the handle 14, the reference plate 1 can be pressed against the wall. The handle 14 is fixedly fitted with anti-slip texture 15, which has a protective effect and prevents the hand from slipping and falling when holding the handle 14.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
