Description

Technical Field

[0001] This utility model belongs to the field of building material testing technology, and in particular relates to a safety testing device for construction engineering materials. Background Technology

[0002] In construction engineering, all raw materials, semi-finished products, building components, and spare parts used in buildings and structures are collectively referred to as building materials. Safety testing of materials is a crucial step in ensuring the quality and safety of buildings. By using scientific testing methods and technologies, quality problems of materials can be effectively identified, avoiding safety hazards caused by substandard materials. Safety testing of building materials is not only a key means of quality control but also an important measure to ensure public safety.

[0003] In particular, strength testing of poured concrete can effectively ensure public safety. Currently, concrete testing is mainly carried out through the rebound method. When using the rebound method, multiple tests need to be performed in a fixed area. Currently, grid lines are drawn directly on the wall, and then the rebound value is measured with a rebound hammer. However, drawing grid lines on the wall takes a lot of time and affects efficiency because there are many areas to draw, generally no less than 10. Secondly, after the grid lines are drawn, they remain on the wall, affecting the aesthetics. Utility Model Content

[0004] The purpose of this invention is to provide a safety testing device for construction materials that eliminates the need to draw grid lines on walls for rebound testing.

[0005] The construction material safety testing equipment includes a frame that is open at the front and back. The frame is a rectangular structure. At least four first inserts parallel to its width direction are provided inside the frame. A first adjustment mechanism is provided on the frame to allow the first inserts to move along their length direction.

[0006] The frame also has at least four second inserts parallel to its length direction, and a second adjustment mechanism for moving the second inserts along its width direction is provided on the frame. A support frame is provided at the bottom of the frame.

[0007] Furthermore, both the first and second insert blocks are provided with 5 rods.

[0008] Furthermore, the first adjustment mechanism includes a plurality of first through holes opened on the side wall along the length of the frame. The first through holes are used for the first insert to pass through and are evenly distributed along the length of the frame. A third groove for inserting the first insert is opened on the inner side wall along the length of the frame corresponding to the first through holes.

[0009] Furthermore, the second adjustment mechanism includes a plurality of second through holes opened on the side wall in the width direction of the frame. The second through holes are used for the second insert to pass through and are evenly distributed along the width direction of the frame. A fourth groove for the insertion of the second insert is opened on the inner side wall in the width direction of the frame corresponding to the second through holes.

[0010] Furthermore, the first insertion block is horizontally positioned, and a sliding groove is provided on the first insertion block for the second insertion block to pass through and slide horizontally.

[0011] Furthermore, a fixing block is vertically fixed to the top of the frame, and a positioning hole is provided on the fixing block.

[0012] Furthermore, the support frame includes a horizontally arranged base plate, with rollers installed at the bottom of the base plate, a fixed plate horizontally fixed at the bottom of the frame, and an adjustment component for adjusting the horizontal height of the fixed plate between the base plate and the fixed plate.

[0013] Furthermore, the adjustment assembly includes an adjustment rod vertically fixed to the top of the base plate, an adjustment tube independently sleeved on the adjustment rod, the adjustment tube being fixed to the bottom of the frame, and a first bolt being provided on the adjustment tube to fix it to the adjustment rod.

[0014] Furthermore, a connecting frame is fixed to the left side wall of the regulating tube, and a sliding rod is independently installed inside the connecting frame. A second bolt is provided on the connecting frame to fix the sliding rod to the connecting frame, and a suction cup is provided at the rear end of the sliding rod that protrudes from the connecting frame.

[0015] Furthermore, the adjusting rod, adjusting tube, sliding rod, and connecting frame are all rectangular structures.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention uses a first and a second insert block to form a grid-like area within a frame. The frame is then attached to a concrete wall, allowing the rebound hammer to perform rebound testing on the wall through the area formed by the first and second insert blocks. Furthermore, the size of a single testing area can be changed by moving the first and second insert blocks, eliminating the need to draw grid lines on the wall, which is more convenient and reduces the likelihood of soiling the wall surface.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is 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.

[0025] This embodiment describes a safety testing device for construction materials, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the frame 1 is a rectangular structure with a rectangular inner wall and an outer wall. The frame 1 has at least four first inserts 2 parallel to its width direction and at least four second inserts 3 parallel to its length direction. The upper and lower sidewalls of the frame 1 are its width, and the length of the frame 1 is its left and right sidewalls.

[0026] The first insertion block 2 and the second insertion block 3 are each provided with 5 rods. 16 small detection areas can be formed between the 5 first insertion blocks 2 and the 5 second insertion blocks 3, which can meet the quantity requirements of the rebound method. Of course, in some embodiments, the first insertion block 2 and the second insertion block 3 can also be 4 rods. The top or bottom wall of the frame 1 and the left or right side wall of the frame 1 act as a rod, so that a small detection area is also formed between the first insertion block 2 or the second insertion block 3 near the inner side wall of the frame 1 and the inner side wall of the frame 1.

[0027] Several first through holes 1.1 are provided on the side wall along the length direction of the frame 1. The first insert 2 is a block structure. The first through holes 1.1 are used for the first insert 2 to pass through, and the first through holes 1.1 are evenly distributed along the length direction of the frame 1, that is, the distance between two adjacent first through holes 1.1 is the same. Corresponding to the first through holes 1.1, a third groove 1.3 is provided on the inner side wall along the length direction of the frame 1 for the insertion of the first insert 2. The third groove 1.3 is opened on the left inner side wall of the frame 1, and the first through hole 1.1 is opened on the right side wall of the frame 1. The first through hole 1.1 is a through hole that connects the left and right sides. The third groove 1.3 and the first through hole 1.1 correspond one-to-one. By inserting the first insert 2 into different first through holes 1.1, the position of the first insert 2 can be adjusted. This section as a whole constitutes a first adjustment mechanism for the first insert 2 to move along the length direction of the frame 1.

[0028] Of course, in some embodiments, the first adjustment mechanism can also be that the first insert 2 is rod-shaped, and a first groove is opened on the right side wall of the frame 1 for the first insert 2 to pass through and slide up and down. The upper limit block of the first insert 2 is close to the right inner side wall of the frame 1. The right end of the first insert 2 extends beyond the frame 1, and the first insert 2 extending beyond the frame 1 is provided with external threads. A nut is fitted on the right end of the first insert 2. By rotating the nut to the left, the limit block is made to fit tightly against the right side wall of the frame 1. The right side wall of the frame 1 is clamped by the nut and the limit block, and the first insert 2 is fixed. The position can be adjusted by sliding the first insert 2 up and down in the first groove.

[0029] Several second through holes 1.2 are provided on the side wall of the frame 1 in the width direction. The second through holes 1.2 are used for the second insert 3 to pass through, and the second through holes 1.2 are evenly distributed along the width direction of the frame 1. Corresponding to the second through holes 1.2, a fourth groove 1.4 is provided on the inner side wall of the frame 1 in the width direction for the insertion of the second insert 3. The second through holes 1.2 are located at the top of the frame 1, and the fourth groove 1.4 is located at the inner bottom of the frame 1. By inserting the second insert 3 into different second through holes 1.2, the position of the second insert 3 is adjusted. This section as a whole constitutes a second adjustment mechanism for moving the second insert 3 along the width direction of the frame 1. Of course, the structure of the second adjustment mechanism can also be the same as the nut structure of another structure in the first adjustment mechanism, that is, the second insert 3 is rod-shaped, a nut is fitted on the top of the second insert 3, and a limit block is fixed on the second insert 3 near the inner top of the frame 1.

[0030] The first insert 2 is horizontally positioned, and a sliding groove 2.1 is provided on the first insert 2 for the second insert 3 to pass through and slide horizontally. The thickness of the second insert 3 is less than the thickness of the first insert 2, so that the second insert 3 can move horizontally within the sliding groove 2.1 on the first insert 2 without obstruction. When the first insert 2 needs to be adjusted, the second insert 3 needs to be removed. In this way, the second insert 3 can also prevent the first insert 2 from detaching. Of course, in some embodiments, the first insert 2 and the second insert 3 can also be staggered, such as the first insert 2 being located in front of the second insert 3. In this way, the first insert 2 and the second insert 3 will not obstruct each other when they are adjusted.

[0031] A fixing block 4 is vertically fixed to the top of the frame 1. The fixing block 4 has a positioning hole. The rear side wall of the fixing block 4 is flush with the rear side wall of the frame 1. After the frame 1 is attached to the concrete wall, a marker is used to make a mark on the wall through the positioning hole of the fixing block 4. In this way, if the detected value is incorrect, it can also be used to locate the original detection area. The contaminated area is also relatively small when marked through the positioning hole on the fixing block 4.

[0032] A base plate 8 is horizontally arranged below the frame 1. Rollers are installed at the bottom of the base plate 8. The rollers are four universal wheels with self-locking function, which facilitates the movement of the base plate 8. A fixing plate 5 is horizontally fixed at the bottom of the frame 1. The rear side wall of the base plate 8 and the rear side wall of the fixing plate 5 do not extend beyond the rear side wall of the frame 1, so as to avoid the base plate 8 and the fixing plate 5 obstructing the fit between the frame 1 and the wall.

[0033] An adjusting rod 9 is fixed to the top of the base plate 8. An adjusting tube 10 is independently fitted onto the adjusting rod 9. The adjusting tube 10 is fixed to the bottom of the frame 1. A first bolt is provided on the adjusting tube 10 to fix it to the adjusting rod 9. The adjusting tube 10 slides up and down on the adjusting rod 9, thereby adjusting the combined length of the adjusting rod 9 and the adjusting tube 10, and adjusting the height of the frame 1 so that the frame 1 can be aligned with the wall at different heights. The height of the frame 1 is also adjusted by the threaded engagement between the adjusting tube 10 and the adjusting rod 9. This section constitutes an adjusting assembly for adjusting the horizontal height of the fixed plate 5. Of course, in some embodiments, the adjusting assembly can also have the adjusting rod 9 as a screw, and the inner wall of the adjusting tube 10 has internal threads. This section, together with the previous section, constitutes a support frame.

[0034] A connecting frame 7 is fixed to the left side wall of the adjusting tube 10. A sliding rod 6 is independently installed inside the connecting frame 7. A second bolt is provided on the connecting frame 7 to fix it to the sliding rod 6. A suction cup 11 is provided at the rear end of the sliding rod 6 through the connecting frame 7. After the frame 1 is attached to the wall, the suction cup 11 is moved by the sliding rod 6 to make the suction cup 11 adhere to the wall. Then, the sliding rod 6 and the connecting frame 7 are fixed by the second bolt to connect the frame 1 to the wall, increase stability, and improve the adhesion between the frame 1 and the wall.

[0035] The adjusting rod 9, adjusting tube 10, sliding rod 6, and connecting frame 7 are all rectangular structures. The outer walls of the connecting frame 7 and the adjusting tube 10 are rectangular, which increases the contact area between the connecting frame 7 and the adjusting tube 10 and enhances their fixing effect. The sliding rod 6 and adjusting rod 9 are square rods, which prevents the sliding rod 6 from rotating inside the connecting frame 7 and the adjusting rod 9 from rotating inside the adjusting tube 10. The rear end of the sliding rod 6 is circular, which makes it easy for the suction cup 11 to be fitted onto the sliding rod 6. Alternatively, the suction cup 11 can be directly attached to the rear end of the sliding rod 6.

[0036] The working principle and technical effects of this embodiment:

[0037] In use, the first insert 2 and the second insert 3 form a grid-lined square within the frame 1. Then, the base plate 8 is moved so that the rear side wall of the frame 1 fits against the wall. The concrete wall in the area between the first insert 2 and the second insert 3 is then tested using a rebound hammer. After the test is completed, the frame 1 is moved, and the next area can be tested directly. There is no need to draw grid lines on the wall, which is more convenient and will not dirty the concrete wall. Moreover, by sliding the first insert 2 and the second insert 3, the size of the area formed by the first insert 2 and the second insert 3 can be adjusted, making it applicable to a wide range of situations.
