Description

Technical Field

[0001] The utility model belongs to the technical field of pressure resistance detection, and in particular relates to a pressure resistance safety detection device. Background Art

[0002] Walls are the main load-bearing components of buildings, and their compressive performance is directly related to the building's load-bearing capacity and stability. Multiple safety inspections are required during construction to promptly detect problems with the building's compressive performance, such as wall cracks, structural deformation, etc., so that appropriate repair and reinforcement measures can be taken to prevent accidents. If the compressive performance is insufficient, the building may be damaged when subjected to external forces (such as wind loads, earthquakes, etc.), seriously threatening people's lives and property.

[0003] The compressive performance that needs to be monitored is mainly divided into two parts: the compressive performance of the wall and the compressive strength of the concrete components. Among them, concrete components (such as beams, columns, etc.) are important load-bearing parts of the building, and their compressive performance is also crucial to the stability of the building.

[0004] The compressive performance of concrete is mainly tested by concrete rebound tester, and the main technical indicators include impact function; spring stiffness of the rebound spring; hammer stroke; maximum static friction of the pointer system and average value of the rigidity of the drill. However, the existing concrete rebound tester is mostly operated by hand, and the following two defects often occur: the measuring instrument of the concrete rebound tester cannot be always placed perpendicular to the surface to be tested, resulting in inaccurate test values, and the test surface is manually painted with an oil pen before testing, which is time-consuming and labor-intensive, resulting in low test efficiency. Therefore, a construction compressive safety detection device is designed to solve the above problems. Utility Model Content

[0021] Example 1

[0022] like Figures 1 to 4 The construction pressure safety detection device shown in the figure includes a test area template 1 and a concrete return flow meter 2. An adsorption positioning frame 3 is arranged above the test area template 1. The inner wall of the adsorption positioning frame 3 is provided with a plurality of first hinge seats 4.

[0023] The utility model sets an adsorption positioning frame 3 and a positioning ring 8 so that the two are vertically parallel. When the adsorption positioning frame 3 is adsorbed onto the measuring area template 1 and the concrete return flow meter 2 is installed onto the positioning ring 8, the concrete return flow meter 2 can be kept vertical to the measured plane. The first swing arm 5 and the second swing arm 6 are flexibly hinged between the adsorption positioning frame 3 and the positioning ring 8, so that the concrete return flow meter 2 can always move within the detection range of the measuring area template 1, so as to realize the accurate detection of the compressive performance value. Finally, five scale grooves 13 are provided on the four sides of the top of the adsorption positioning frame 3 to form a 4X4 specification detection space 14. The detection personnel can choose whether to make marks with a marker pen or directly perform spring pressure detection according to experience according to the scale grooves 13, thereby improving the detection efficiency and making the detection data more accurate.

[0024] Example 2

[0025] like Figures 1 to 4 The construction compressive safety detection device shown in the figure includes a measuring area template 1 and a concrete rebound meter 2. It should be noted that the concrete rebound meter is a tool used to evaluate the surface hardness and strength of concrete. It mainly uses the principle of energy conservation to hit the concrete surface with a heavy hammer, and evaluates its surface hardness and compressive strength according to the rebound height of the concrete surface. For general components, in order to ensure the comprehensiveness and accuracy of the evaluation results, the number of measuring areas should not be less than 10, and 16 rebound values ​​should be read in each measuring area. The specific method of use is: first, place the measuring instrument of the concrete rebound meter perpendicular to the surface to be measured, and align the hammer head with the measuring point, then use the handle to drop the impact hammer perpendicular to the measuring point, so that the hammer head impacts the concrete surface, after the impact is completed, observe the rebound value on the measuring instrument on the instrument, and record the rebound value, and convert the rebound value into the strength value of the concrete according to the model and instruction manual of the concrete rebound meter used.

[0026] During the test, the test area template 1 can be placed at the position to be tested first, and then the staff holds the concrete backflow meter 2 and aims the hammer at the test area template 1, pressing down while moving until 16 rebound values ​​are read. In order to facilitate the staff's test, an auxiliary tool is specially designed to position the concrete backflow meter 2 and the test area template 1, driving the concrete backflow meter 2 to take the correct way to complete the test sampling; the auxiliary tool includes an adsorption positioning frame 3, which can be directly adsorbed on the test area template 1, and then only the concrete rebound test hammer is fixed on the adsorption positioning frame 3, and the concrete backflow meter 2 and the test area template 1 can be indirectly positioned. The shape of the adsorption positioning frame 3 is consistent with the test area template 1, both of which are squares with equal length and width, and the lower frame of the adsorption positioning frame 3 is larger than the test area template 1, so that the adsorption positioning frame 3 can directly wrap the test area template 1, and the two are combined into an integrated design to further accurately position the concrete backflow meter 2.

[0027] In order to realize that after the concrete return flow meter 2 is connected to the adsorption positioning frame 3, the concrete return flow meter 2 can move forward, backward, left and right, and complete the reading of 16 ranges and 16 rebound values, the connecting parts of the concrete return flow meter 2 are set as follows: it is known that the adsorption positioning frame 3 has 4 inner walls, each of which is provided with a first hinge seat 4, and each of the first hinge seats 4 is rotatably provided with a first swing rod 5, and a positioning ring 8 is also provided. The positioning ring 8 is designed as a circular ring and is located above the adsorption positioning frame 3. It is used to install the concrete return flow meter 2, so that the concrete return flow meter 2 can pass through the positioning ring 8. It is installed above the adsorption positioning frame 3, and the moving range of the concrete return flow meter 2 is indirectly positioned in the measuring area template 1, so as to further accurately detect the value; then the same number of second hinge seats 7 are installed to the inner wall of the positioning ring 8, and then the second swing arm 6 is rotatably set on the second hinge seat 7. At this time, the lower end of the second swing arm 6 and the upper end of the first swing arm 5 are close to each other, and then the two are connected by a fastening nut, so that the concrete return flow meter 2 can be driven to move forward, backward, left and right in the measuring area template 1 with the flexible cooperation of the first swing arm 5 and the second swing arm 6, and complete the reading of the values ​​in 16 ranges.

[0028] Example 3

[0029] like Figures 1 to 4 The construction compressive safety detection device shown in the figure installs the concrete return flow meter 2 on the positioning ring 8, and through the flexible connection between the positioning ring 8 and the adsorption positioning frame 3, drives the concrete return flow meter 2 in the positioning ring 8 to move forward, backward, left and right in the measuring area template 1, completes the numerical reading of 16 ranges, and then realizes the detection of the compressive strength of the wall. The outer side of the positioning ring 8 is evenly provided with a plurality of sliding holes 9, the number of the sliding holes 9 is 4, and they are indirectly arranged with the second hinge seat 7. A clamping rod 10 is slidably arranged in the sliding hole 9, and a clamping block 153 with a quarter arc shape is arranged at the inner end of the clamping rod 10. The four clamping blocks 153 are all moved inwardly to clamp the concrete return flow meter 2, thereby completing the installation of the concrete return flow meter 2 on the positioning ring 8; at the same time, in order to prevent the concrete return flow meter 2 from accidentally falling when the clamping block 153 is clamped on the concrete return flow meter 2, a spring 11 is also provided, and the spring 11 is sleeved on the clamping rod 10 and connected between the inner wall of the positioning ring 8 and the clamping block 153. When the spring 11 is a tension spring 11, it can generate resistance to the clamping rod 10 under the tensile force of the spring 11 itself, driving the clamping rod 10 to keep moving inward at all times, and firmly clamping the concrete return flow meter 2 between the clamping blocks 153, thereby preventing the concrete return flow meter 2 from falling and being damaged, thereby increasing the detection cost.

[0030] In addition, an adjusting handle 12 is provided at the outer end of the clamping rod 10. The inner diameter of the adjusting handle 12 is larger than the sliding hole 9, so that the staff can hold the adjusting handle 12 and easily pull the clamping rod 10 outward, and no longer clamp the concrete return flow meter 2, thereby realizing the recovery of the concrete return flow meter 2; and the positioning ring 8 and the adsorption positioning frame 3 can also be folded and recovered by the first swing arm 5 and the second swing arm 6 when not in use, which is convenient for the staff to carry and use, thereby improving the convenience of use.

[0031] Example 4

[0032] It is understandable that the concrete rebound test hammer will read 16 rebound values ​​in each measuring area to ensure that these measuring areas are evenly distributed on the concrete structure, thereby covering different parts of the entire structure and reducing errors caused by local differences. Moreover, since 16 measuring areas are selected for measurement at one time, the test efficiency can be significantly improved compared with the measurement of a single measuring area or a small number of measuring areas. In actual operation, in order to control the distance between measuring points to be no less than 20 mm, most inspectors will use a marker to subdivide the measuring area into four rows and four columns, so that each measuring point is individually marked with a rebound range, so that the inspectors can accurately rebound in each small frame when the concrete rebound test hammer rebounds. Therefore, in this embodiment, a plurality of scale grooves 13 are also provided on the top four sides of the adsorption positioning frame 3, and the number of scale grooves 13 is 5, so that the space in the adsorption positioning frame 3 can be formed into a 4X4 specification detection space 14, and the inspectors can choose whether to mark with a marker according to the scale grooves 13, or directly perform the spring pressure test according to experience, standardize the test process, and make the test data more accurate.

[0033] In order to further reduce fatigue and trembling caused by long-term holding of the concrete reflux meter 2 by human hands, which in turn causes the concrete reflux meter to be unable to be in a vertical state with the surface to be tested, a handle 16 is also provided on the top of the concrete reflux meter 2, and an arc groove 17 is provided in the handle 16 close to the human hand holding. The arc groove 17 has three bending arcs, so that it can be placed on the four fingers of the human hand to reduce the holding pressure; therefore, the tester can hold the concrete reflux meter 2 by holding the handle 16, and the positioning ring 8 also has a certain supporting force on the concrete reflux meter 2, which effectively reduces the pressure of the tester on the concrete reflux meter 2 when holding it, keeps the concrete reflux meter and the surface to be tested in a vertical state, and obtains accurate test values.

[0034] Example 5

[0035] Furthermore, the number of measurement areas of the concrete rebound tester should not be less than 10, mainly to ensure the comprehensiveness and accuracy of the evaluation results, and the distance between two adjacent measurement areas should not be greater than 2m to ensure the continuity of the evaluation results in spatial distribution, and then a measurement area template 1 can be used as a reference. Therefore, this embodiment also designs the measurement area template 1 to be spliced, and the inspection personnel can splice multiple measurement area templates 1 before inspection, and then place them on the plane to be inspected, so that there is no need to use a marker pen to draw manually, reducing the inaccuracy of the inspection results.

[0036] That is, a plurality of test area templates 1 can be provided, and they are mutually connected through the snap assembly 15. The snap assembly 15 includes a T-shaped slot 151, a slide plate 152 and a clamping block 153. Two T-shaped slots 151 are provided on the right side of the test area template 1. The T-shaped slots 151 are provided one above and one below. Correspondingly, a clamping block 153 is provided on the left side of the test area template 1 through the slide plate 152. The area of ​​the clamping block 153 is the same as the lateral area of ​​the T-shaped slot 151. The T-shaped slot 1 The vertical width of 51 is adapted to the size of the slide plate 152, and then the test area template 1 to be spliced ​​can be installed from top to bottom, and the block 153 on the test area template 1 to be spliced ​​is inserted into the slot of the initial splicing test area template 1, and then the slide plate 152 slides downward through the "I" on the T-shaped slot 151, driving the block 153 to be stuck on the "I" on the T-shaped slot 151, completing the splicing of the two test area templates 1, and cooperating with multiple uses of the test area templates 1.
