Description
Technical Field
[0001] The present invention relates to the technical field of engineering detection, and specifically to an engineering quality stability detection device and a detection method. Background Art
[0002] Construction engineering refers to the planning, surveying, design, construction, completion and other technical work for the new construction, renovation or expansion of buildings and ancillary structures, as well as the completed engineering entities and the installation works of their supporting lines, pipelines and equipment. It also refers to the construction projects of various houses and buildings, also known as construction work volume. This part of the investment must start construction and use materials, and can only be realized through construction activities. The construction projects of "buildings" include factories, theaters, hotels, stores, schools, hospitals and residences, etc. Their new construction, renovation or expansion must start construction and use materials, and can only be realized through construction activities; "ancillary structures" refer to water towers, bicycle sheds, pools, etc.配套 to the buildings.
[0003] After the start of the project, bricks need to be used for building to construct the houses and walls in the project. After the production of bricks, in order to ensure the stability of the bricks when building houses and walls, the bricks need to be detected, and thus an engineering quality stability detection device is used.
[0004] When most of the existing engineering quality stability detection devices are in use, generally, the motor and the hammering member cooperate with each other to detect the strength of the bricks through the hammering member. However, most of the existing engineering quality stability detection devices cannot detect the walls built with bricks, so the stability of the walls during use cannot be ensured, resulting in certain risks after the walls are built and affecting the normal use of the walls.
[0005] Therefore, the present invention provides an engineering quality stability detection device and a detection method to solve the above problems. Summary of the Invention
[0006] The present invention provides an engineering quality stability detection device and a detection method, aiming to solve the problems proposed in the background art.
[0007] To achieve the above object, the present invention provides the following technical solution: An engineering quality stability detection device includes a detection box body and a sealing plate slidably connected to one side of the detection box body. A mortar joint detection mechanism is installed inside the detection box body, and a control mechanism is installed on the inner wall of the detection box body; The grout joint detection mechanism includes several mounting plates arranged in a rectangular array and slidably connected inside the detection chamber. Probes with torque sensors mounted on their surfaces are fixedly connected in a path array on the surface of each mounting plate. A buffer plate is located on one side of each probe, and a buffer spring, also fixedly connected to the mounting plate, is fixedly connected in a path array on one side of the buffer plate. The buffer spring corresponds to the probe. A support plate is fixedly connected to one side of each mounting plate, and a laser marker corresponding to the probe is fixedly connected in a path array on the upper surface of the support plate. A connecting rod is fixedly connected in a path array to every two opposite sides of the mounting plate.
[0008] As a preferred technical solution of this application, the grout joint detection mechanism further includes movable plates that are fixedly connected to the upper and lower surfaces of two of the mounting plates respectively. The surfaces of the movable plates are provided with movable grooves in a path array. Both sides of the movable grooves are slidably connected with clamping springs. One end of the two clamping springs is fixedly connected to a clamping plate corresponding to the movable groove. A strain gauge force sensor is fixedly connected to one side of the clamping plate in a path array.
[0009] As a preferred technical solution of this application, the grout joint detection mechanism further includes threaded cylinders that are fixedly connected to the outside of the other two mounting plates respectively. The threaded cylinders are internally threaded with threaded rods. One end of the threaded rods is fixedly connected to a drive motor that is fixedly connected to the detection box. The other end of the clamping spring is fixedly connected to a limiting plate that is fixedly connected to the moving plate.
[0010] As a preferred technical solution of this application, the control mechanism includes a support plate slidably connected to the inside of the detection box. The upper surface of the support plate is fixedly connected with clamping springs in a rectangular array. One end of the clamping springs is fixedly connected to a clamping plate slidably connected to the support plate. The surface of the clamping plate is magnetically attracted with an extension plate corresponding to the clamping plate. The surface of the extension plate is sleeved with a guide box fixedly connected to the clamping plate.
[0011] As a preferred technical solution of this application, the control mechanism further includes a sliding block that is slidably connected to the inside of the detection chamber and fixedly connected to the support plate. The surface of the sliding block is threadedly connected to a lead screw that is rotatably connected to the detection chamber through a bearing seat. One end of the lead screw is fixedly connected to a servo motor that is fixedly connected to the inside of the detection chamber. The support plate corresponds to the detection chamber and the sealing plate.
[0012] As a preferred technical solution of this application, the control mechanism further includes a water storage box fixedly connected to the inside of the detection box. A spray pipe is connected to one side of the water storage box via a water pump. A spray head inserted into the inside of the detection box is fixedly connected to one end of the spray pipe. A water inlet pipe is fixedly connected to the upper surface of the water storage box.
[0013] As a preferred technical solution of this application, the control mechanism further includes an electric heating plate that is fixedly connected to one side of the water storage box by bolts. A heat-conducting pipe inserted into the inside of the detection box is fixedly connected to one side of the electric heating plate. The spray pipe is installed inside the electric heating plate, and the heat-conducting pipe is inserted into the inside of the water storage box.
[0014] A detection method for an engineering quality stability testing device, applied to any one of the above-mentioned engineering quality stability testing devices, specifically includes the following steps: S1: Place the newly built wall on the support plate, limit the wall based on the clamping plate and extension plate, and use a servo motor and lead screw to drive the support plate and the wall into the interior of the detection box. S2: Close the sealing plate and start the drive motor so that the threaded rod and the threaded cylinder cooperate with each other, driving the mounting plate and the probe to be inserted into the mortar joint of the wall. Based on the settings of the torque sensor and the probe, record the torque resisted by the probe, infer the filling density of the mortar joint, and detect the filling density of the mortar joint. S3: The mounting plate moves, synchronously driving the moving plate and the clamping plate to move, so that the clamping plate fits into the mortar joint. Based on the continuous movement of the moving plate, the strain gauge force sensor fits into the mortar joint to detect the stress distribution of the mortar joint. The clamping spring and the buffer spring buffer the resistance between the probe and the strain gauge force sensor. S4: While inspecting mortar joints, the temperature and humidity inside the inspection chamber are controlled by the spray head and heat pipes to adjust the environment inside the inspection chamber, thereby enabling the inspection of the wall's environmental adaptability while inspecting mortar joints, achieving multi-dimensional inspection of project quality.
[0015] The mortar joint detection mechanism and other structures work together to drive the motor, which moves the mounting plate and probe. This allows the probe to be inserted into the mortar joint of the wall at a uniform speed. A torque sensor detects the torque encountered by the probe, thereby deducing the filling density of the mortar joint. This allows for the detection of the mortar joints in the engineering wall. Based on the detection results of the mortar joint filling density, the stability of the wall construction is reflected. This prevents the load from being concentrated at a few brick contact points due to gaps in the mortar joints after the wall construction is completed. The local compressive stress may exceed the compressive strength of the bricks, leading to brick breakage and affecting the use of the wall. Furthermore, the cooperation between the buffer spring and the buffer plate buffers the insertion force of the probe, ensuring that the probe automatically stops insertion when it comes into contact with a hard brick, thus avoiding damage to the probe. Based on the setup of the mortar joint detection mechanism, during the mortar joint filling density detection process, the moving plate moves with the installation plate. After the probe is inserted into the mortar joint, the clamping plate drives the strain gauge force sensor to fit into the mortar joint, detecting the stress distribution in the mortar joint, and further detecting the stability of the project quality. This avoids the situation where uneven stress distribution causes the local stress of the bricks to exceed the brick's bearing limit, forming a stress concentration area that leads to wall cracking and affects the stability of the project quality. Based on the setup of the testing chamber and control mechanism, the temperature and humidity inside the testing chamber are controlled by spray heads and electric heating plates to simulate different environments. This allows the wall to undergo mortar joint testing in different environments, thereby simultaneously conducting environmental adaptability testing during the mortar joint testing process and further testing the stability of the project quality.

The clamping plate 18 clamps the wall by the elastic force of the clamping spring 17. Then, the servo motor 22 is started, and its output end drives the lead screw 21 to rotate, so that the sliding block 20 moves the support plate 16 into the detection box 1, and the wall moves into the detection box 1 at the same time.

A laser marker 7 corresponding to the probes 3 is fixedly connected in a path array on the upper surface of the support plate 6. A connecting rod is fixedly connected in a path array to the opposite sides of every two corresponding mounting plates 2. Among them, the mounting plate 2 is used to support the probe 3 and the buffer plate 4; Among them, probe 3 and torque sensor are used to detect the torque of probe 3 when it is resisted in the mortar joint; Among them, the buffer plate 4 and the buffer spring 5 are used to buffer the force of the probe 3 being inserted into the mortar joint; Among them, the support plate 6 is used to install the laser line marker 7, and the laser line marker 7 is used to guide the movement of the mounting plate 2; Specifically, the drive motor 15 is started, and its output end drives the threaded rod 14 to rotate, thereby causing the threaded cylinder 13 to move the mounting plate 2, so that the probe 3 and the torque sensor are inserted into the mortar joint. Based on the setting of the torque sensor and the probe 3, the torque resisted by the probe 3 is recorded, the filling density of the mortar joint is deduced, the filling density of the mortar joint is detected, and the stability of the project quality is detected. The buffer spring 5 and the buffer plate 4 work together to buffer the insertion force of the probe 3, ensuring that the probe 3 automatically stops being inserted when it comes into contact with a hard brick, thus avoiding damage to the probe 3. The grout joint detection mechanism also includes movable plates 8 that are fixedly connected to the upper and lower surfaces of two mounting plates 2 respectively. The surface of the movable plates 8 is provided with movable grooves 9 in a path array. Both sides of the movable grooves 9 are slidably connected with clamping springs 10. One end of the two clamping springs 10 is fixedly connected to the corresponding clamping plate 11 of the movable grooves 9. One side of the clamping plate 11 is fixedly connected with a strain gauge force sensor 12 in a path array. The movable plate 8 and the movable groove 9 are used to support the clamping plate 11; The clamping plate 11 is used to install the strain gauge force sensor 12; Among them, the strain gauge force sensor 12 is used to detect the stress distribution in the mortar joint; Specifically, when the mounting plate 2 moves, it simultaneously drives the moving plate 8 and the clamping plate 11 to move, so that the clamping plate 11 fits into the mortar joint. Based on the continuous movement of the moving plate 8, the strain gauge force sensor 12 fits into the mortar joint to detect the stress distribution of the mortar joint, and further detect the stability of the project quality. This avoids the local stress of the bricks exceeding the brick's bearing limit due to uneven stress distribution, which would form a stress concentration area and cause the wall to crack, thus affecting the stability of the project quality.
