Description

Technical Field

[0001] The invention relates to the technical field of building material detection, in particular to a building material detection device for building construction. Background Art

[0002] Building materials refer to all materials used in construction projects. In a broad sense, it includes all kinds of materials that constitute the entities of buildings and structures, as well as auxiliary materials required in the construction process.

[0003] In today's construction field, the quality of building materials is directly related to the safety, durability and stability of the entire construction project. With the continuous development of construction technology and the increasing scale of construction, the performance requirements for building materials are becoming more and more stringent, and the requirements for material testing are also getting higher and higher.

[0004] The prior art publication number is CN118258741A, which provides a building material detection device for construction, and relates to the technical field of building material porosity detection. The device comprises a detection box and a test block body. A test cavity is provided inside the detection box, and a lower sealing shell is fixedly connected to the inner wall of the test cavity. A collecting cavity is provided inside the detection box. The device for detecting building materials for construction, when detecting the test block body, can use a heating plate and a pressing plate to press liquid thermoplastic material into the pores of the test block body, and then can drive the upper and lower clamping blocks to clamp the test block body through a second electric push rod, and cooperate with a fan to sequentially deliver strong wind to each side of the test block body, so as to blow out the solid thermoplastic material in the effective pores in the test block body, and then use a weight method to weigh the blown solid thermoplastic material, so as to obtain the effective porosity of the test block body, thereby ensuring the actual effect achieved after the porous concrete construction.

[0005] Although the above-mentioned prior art uses air blowing to detect the effective pores of the test block, the use of solid thermoplastic material blowing is only suitable for the case where the test block has obvious pores. For test blocks with small pores or pores not located on the surface, the penetration method is still used for detection. The penetration method includes the steady-state penetration method and the transient penetration method. Both test methods are to first seal the sides of the test block, and then use water with different water pressures to pass through the upper and lower sides of the test block, record the passing time, the pressure at both ends of the test block, and the thickness of the test block. The permeability can be calculated using the expression of Darcy's law. The difference between the steady-state penetration method and the transient penetration method lies in the use of stable water pressure and variable pressure water pressure. In the experimental process of the steady-state penetration method, the existing equipment uses manual operation to first seal the sides of the test block, and then conduct the experiment. During the experiment, the water tank pressure cannot be changed. If the thickness of the test block is large, it is necessary to increase the pressure on both sides of the test block, which can only be controlled by another pressurizing device, and the device detection test is inconvenient.

[0006] It can be seen that a building material detection device for construction is needed to solve the problem mentioned in the above background technology that the existing steady-state permeability method uses manual operation to first seal the side of the test block during the experiment and cannot simply increase the pressure difference on both sides of the test block during the experiment.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0037] In this embodiment, the steady-state permeability method is based on Darcy's law. Under a stable fluid flow state, the permeability of porous materials is measured. It is necessary to measure the volume flow rate of the fluid, the cross-sectional area perpendicular to the fluid flow direction, the head difference of the fluid at both ends of the material, that is, the pressure difference, and the thickness of the material. When other parameters are kept unchanged in the experiment, the permeability can be calculated by measuring the flow rate and the pressure difference. The existing equipment generally mainly includes a liquid supply system such as a constant pressure water tank, a test specimen porous material sample, which is usually cylindrical or rectangular in shape, and the side is sealed to only allow the fluid to pass through the upper and lower surfaces, a pressure measurement system for measuring the pressure difference at both ends of the specimen, such as a pressure sensor and a collection system for collecting the fluid passing through the specimen. For example, in the side sealing of the measuring cylinder, manual operation is required. In this embodiment, the side of the test block is sealed by spraying sealing paint. In fact, it can also be wrapped with a sealing strip. In this embodiment, the sealing material can be changed according to actual needs. A controller is installed in the device, and the operation of the device experiment can be controlled by the controller.

[0038] Specifically, the output end of the driving motor 201 is connected to the output shaft, the first pulley 202 is located on the outside of the output shaft, the retaining frame 204 is located above the first pulley 202 and on the outside of the output shaft, and the top of the output shaft is connected to a support column through a bearing, one end of the support column is connected to the first end gear 203, and the other end of the support column is in contact with the ground, a nozzle is installed on the side of the installation box 1 away from the water tank assembly 5, and a collecting bin is arranged under the nozzle, and the top of the nozzle is connected to the spraying equipment through a nozzle.

[0039] In this embodiment, a sealed door is provided on the outside of the installation box 1. After closing, the experimental environment can be free from external factors. After opening, some equipment can be manually adjusted, such as a handle 509. An opening is provided at the top of the installation box 1. The setting of the opening facilitates the folding of the box body 501 for telescopic operation. The interior of the installation box 1 includes two spaces, which are located on both sides of the movable flip assembly 2. One group is the space where the water tank assembly 5 is located, which is used for penetration experiments, and the other group is the space where the paint spray head is located, which is used for sealing the test block. A partition can be provided in the middle, and the flip door 410 is flipped and located on one side of the partition. The flip door 410 itself is provided with an opening, which can bypass the position of the movable flip assembly 2, so that the two spaces are not completely sealed, but can be divided to a certain extent. When the drive motor 201 is started, the flip door assembly 4 will be linked, so the flip door assembly 4 can be closed when the movable flip assembly 2 drives the test block to rotate to the side of the paint spray head, and the flip door assembly 4 can also be closed when the penetration experiment is performed. The user can adjust according to the actual usage. A drying device can be installed on one side of the paint spray head to accelerate the drying of the sealing paint and shorten the waiting time.

[0040] Specifically, a motor is installed at one end inside the installation bin 206, and the output end of the motor passes through the rotating frame 301 and is connected to the central gear 305. A large turbine 302 is arranged at the middle position inside the rotating frame 301, and a large worm 303 is meshed above the large turbine 302. Both the large worm 303 and the large turbine 302 can rotate inside the rotating frame 301, and a rotating coupling 304 is connected to one side of the large turbine 302. Two ends of the rotating coupling 304 are correspondingly connected to two sets of transmission gears 306, and the two sets of transmission gears 306 are meshed with the central gear 305. The other side of the transmission gear 306 is meshed with an external gear 307, and the number of external gears 307 is two sets.

[0041] In this embodiment, the driving motor 201 can be a forward and reverse motor. After starting, it drives the adjusting component 3 to rotate from the bottom of the water tank component 5 to the bottom of the paint spray head, and can also rotate back, from the bottom of the paint spray head to the bottom of the water tank component 5. In the adjusting component 3, there are no partitions on both sides of the rotating frame 301, and the interior is hollow. A partition is provided on the front side, and a vertical groove is opened on the partition. Two groups of first vertical shafts 309 pass through the vertical groove and extend to the outside thereof. A fixing plate is provided inside the rotating frame 301 to fix the large worm 303. A handle can be installed at one end of the large worm 303 for easy rotation. The rotation of the large worm 303 drives the large turbine 302 to rotate, which can prevent reversal. A through hole is provided in the middle of the large turbine 302, which is located at the rotating The motor output shaft on the rear side of the frame 301 passes through the through hole and is connected to the central gear 305. The two ends of the rotating shaft 304 are connected to the two sets of transmission gears 306 through bearings and shafts. When the central gear 305 is driven by the motor to rotate, it will drive the transmission gear 306 to rotate and also drive the outer gear 307 to rotate. The rotation of the outer gear 307 will drive the first vertical shaft 309 to rotate. The second vertical shaft 313 is rotated through the rotation of the sleeve ring 310, the Z-shaped shaft 311 and the vertical auxiliary shaft 312, thereby rotating the test block clamped in the middle. Therefore, the test block can be rotated when being sprayed, so that the outer side of the test block can be evenly sprayed by the paint spray head. The test block can be a rectangular structure or a cylindrical structure.

[0042] Specifically, one side of the central gear 305, the transmission gear 306 and the external gear 307 are all connected to the auxiliary frame 308, one side of the two sets of external gears 307 are all connected to the first vertical axis 309, and one end of the first vertical axis 309 is connected to the sleeve ring 310, one end of the sleeve ring 310 is hinged with a Z-shaped axis 311, and one side of the sleeve ring 310 is connected to a vertical auxiliary axis 312, the other end of the Z-shaped axis 311 is hinged with a second vertical axis 313, and the second vertical axis 313 is located on one side of the vertical auxiliary axis 312, one end of the second vertical axis 313 is connected to a gasket, and the gasket is located at both ends of the test block.

[0043] In this embodiment, the rotating large worm 303 is separated from the rotating center gear 305. The center gear 305 is driven by a motor on the rear side of the rotating frame 301, and the large worm 303 is manually driven. The large worm 303 drives the large turbine 302 to rotate. The rotation of the large turbine 302 drives the rotating connecting shaft 304 to rotate, thereby changing the position of the transmission gears 306 located on both sides of the center gear 305. With the assistance of the front auxiliary frame 308, the positions of the outer gear 307 and the transmission gear 306 are changed. The attached figure shows the situation where the five groups of gears are located on the same vertical line, and the two groups of first vertical axes 309 are the farthest apart. By rotating the large worm 303, the positions of the five groups of gears can be changed. Although they are always in a meshing state, they are no longer located on the same vertical line.

[0044] See also Figure 10-11 A building material detection device for construction, wherein two spaces inside an installation box 1 are separated by a flip door assembly 4, and a movable flip assembly 2 is linked with the flip door assembly 4.

[0045] In this embodiment, the flip door 410 moves back and forth with the movement of the worm gear set 402, and its states are divided into horizontal and vertical states. When the flip door 410 is in the vertical state, it is located in the middle position of the internal space of the installation box 1, and the internal space of the installation box 1 is blocked as a whole. A groove is opened inside the flip door 410, and the shape of the groove matches the outer contour of the driving motor 201 and other related parts to avoid mutual interference. Because the flip door 410 itself is fixedly installed in the middle position inside the installation box 1, the movement of the flip door 410 does not interfere with the setting of the flip door 410 itself, and the belt between the first pulley 202 and the second pulley 401 can also pass through the groove. Sealing pads can be set on the four sides of the flip door 410, and the two sides can also be assisted by limit blocks matching the inner wall of the installation box 1. The material itself can be a lighter plate material, which is convenient for flipping back and forth.

[0046] Specifically, the flip door assembly 4 includes a second pulley 401, and the second pulley 401 is connected to the first pulley 202 by a belt, a worm gear group 402 is arranged above the second pulley 401, and the worm gear group 402 includes a turbine and a worm that mesh with each other, and the worm is located above the second pulley 401, a pulley group 403 is connected to one side of the worm gear group 402, and the rear side of the pulley group 403 is connected to a driving gear 404, an outer sleeve shaft 406 is arranged above the driving gear 404, and a moving rack 405 is arranged inside the outer sleeve shaft 406, teeth are arranged at both front and rear ends of the moving rack 405, and the driving gear 404 passes through the outer sleeve shaft 406 and meshes with the teeth at the rear end of the moving rack 405, and the end of the moving rack 405 is connected to the hinge block 408.

[0047] In this embodiment, the worm gear set 402 can prevent reversal to a certain extent. In this embodiment, the worm gear set 402, the pulley set 403, the driving gear 404 and the outer sleeve shaft 406 are all arranged on a mounting plate extending from the inside of the mounting box 1, and the mounting plate is used as a support to meet the operation of the flip door assembly 4. When the motor starts to drive the second pulley 401 to rotate, the second pulley 401 drives the worm gear set 402 to rotate. The turbine in the worm gear set 402 is coaxial with a group of pulleys in the pulley set 403, so it will drive the entire pulley set 403 to rotate. Another group of pulleys in the pulley set 403 is coaxial with the driving gear 404, so it will drive the driving gear 404 to rotate. The rear side of the driving gear 404 is connected to the mounting box 1 through a shaft and a bearing. The outer sleeve shaft 406 is connected to the mounting plate extending from the inner wall. The rotation of the driving gear 404 will drive the movable rack 405 to extend or retract from the inside of the outer sleeve shaft 406. Because the lower end of the movable rack 405 is provided with teeth meshing with the driving gear 404, the outer sleeve shaft 406 is a hollow structure, one end of which is fixed to the inner wall of the mounting box 1. Matching limit blocks and limit grooves can be provided between the outer sleeve shaft 406 and the movable rack 405 to assist the movement of the movable rack 405.

[0048] Specifically, a half gear 407 is meshed below the front end teeth of the movable rack 405, and a hinge block 408 is hinged on the rear side of the half gear 407, the bottom end of the half gear 407 is connected to an extension rod 409, one side of the extension rod 409 is connected to a flip door 410, the inner wall of the installation box 1 is connected to a limiting groove 411, and the hinge block 408 moves inside the limiting groove 411.

[0049] In this embodiment, the forward and backward movement of the movable rack 405 will also drive the hinge block 408 forward and backward, and the half gear 407 hingedly connected on one side of the hinge block 408 will also move together. However, due to the hinged connection, when the hinge block 408 moves to the turning point of the limiting groove 411, the half gear 407 will rotate due to the engagement with the front end teeth of the movable rack 405, thereby causing the horizontally arranged flip door 410 to rotate and flip from a horizontal state to a vertical state. The limiting groove 411 includes a vertical portion and a horizontal portion, and the vertical portion and the horizontal portion are connected at the end. The extension rod 409 is connected to the flip door 410, and the extension rod 409 and the flip door 410 will both rotate with the rotation of the half gear 407.

Parts such as the top plate 502, the bottom plate 503 and the lifting frame 504 are located in the water, so they can be made of materials that are not easy to corrode. In this embodiment, water enters the interior of the folding box 501 from the through water pipe at the top, and then is discharged from the drain pipe at the bottom. After the pressure at both ends of the test block is determined, the folding degree of the folding box 501 will not change in the experiment, and the pressure in the experiment will not change.

[0052] Specifically, a water pipe is provided at the top of the folding box body 501, and the water pipe passes through the top plate 502 and extends to the bottom thereof, a through hole is opened inside the bottom plate 503, and the through hole is connected to the drain pipe 510, a control valve is connected to the outside of the drain pipe 510, and a pressure detection device is installed below the control valve, a collection box is provided inside the installation box 1 below the water tank assembly 5, and a detection head and a pressure detection device are provided above the collection box.

The side turbine 508 cooperates with the threaded worm 507 to have a certain anti-reversal function. When the handle 509 is released, the hinge angle of the lifting frame 504 will not change. Even if there is a certain amount of water inside the folding box 501, it will not interfere with the experiment. A water level sensor can be installed at the top of the folding box 501. When the water level drops, the water supply pump will pump water into the folding box 501 to maintain a certain water level and keep the drainage water pressure normal.

[0054] Specifically, the lifting frame 504 includes an upper hinged short axis 5041, a first tilting axis 5042 and a second tilting axis 5043. The first tilting axis 5042 and the second tilting axis 5043 are hinged at a middle position, and one end of the first tilting axis 5042 and the second tilting axis 5043 is hinged to the upper hinged short axis 5041, and the other end is hinged to the lower hinged short axis 5044. One end of the upper hinged short axis 5041 is hinged to the top plate 502, and one end of the lower hinged short axis 5044 is hinged to the bottom plate 503. The lifting frame 504 is hinged on four sides of the top plate 502 and the bottom plate 503.

[0055] In this embodiment, when the handle 509 is shaken, the rotation of the side turbine 508 will drive the threaded worm 507 to rotate. The rotation of the threaded worm 507 in conjunction with the limit of the fixed cylinder will drive the limit threaded shaft 506 to rise and fall, thereby driving the lifting frame 505 to rise and fall. The lifting and lowering of the lifting frame 505 will drive the lifting frame 504 to expand or compress, thereby expanding or shrinking the distance between the top plate 502 and the bottom plate 503, and then drive the outer folding box 501 to fold or unfold, thereby changing the volume.

[0056] Specifically, limiting holes are provided on all four sides of the lifting frame 505, and the limiting holes match the axes at the hinges of the first tilting axis 5042 and the second tilting axis 5043. A groove is vertically opened on the limiting threaded axis 506, and a fixed cylinder matching the groove is installed on the outer side of the limiting threaded axis 506. The limiting threaded axis 506 penetrates the folding box body 501 and extends to the bottom thereof, and a seal is provided at the contact between the folding box body 501 and the limiting threaded axis 506. The threaded worm 507 rotates at the bottom of the folding box body 501, and a vertical plate is connected to the bottom of the folding box body 501. A handle 509 is connected to one side of the side turbine 508, and the handle 509 penetrates the vertical plate and extends to the outside thereof.

[0057] In this embodiment, the position where the limiting threaded shaft 506 contacts the folding box body 501 is sealed, so that even if the limiting threaded shaft 506 is raised or lowered and passes through the folding box body 501, water leakage will not occur. In this embodiment, the handle 509 can be rotated by a motor to improve the degree of automation of the device, or it can be manually controlled. As for whether to use manual rotation or electric drive, it can be selected according to actual conditions.

[0058] When in use, it is necessary to connect an external power supply, which provides electrical energy for the device so that the device can operate normally. First, the large worm 303 is shaken, so that the large worm 303 drives the large turbine 302 to rotate, and the large turbine 302 drives the rotating shaft 304 to rotate, so that the position of the transmission gear 306 on both sides of the central gear 305 changes. With the cooperation of the auxiliary frame 308, the position of the external gears 307 on both sides will also change, and the position of the first vertical axis 309 output from one side of the external gear 307 will change, so that the distance between the two groups of first vertical axes 309 is extended or shortened, so that the clamping piece can better adapt to the size of the test block, and the test block is clamped in the middle, and the drive motor 201 is started, so that the drive motor 201 drives the first pulley 202 and the retaining frame 204 to rotate, and the retaining frame 204 drives the second end gear 205 to rotate around the first end gear 203 The second end gear 205 meshes with the first end gear 203 so that it also rotates. The second end gear 205 rotates while revolving, thereby driving the rotating frame 301 to revolve and rotate as a whole, so that the rotating frame 301 moves to the side of the installation box 1 away from the water tank assembly 5, and at the same time rotates from the original vertical state to the horizontal state, located below the paint spray head. When the paint spray head is spraying paint, the motor on the rear side of the rotating frame 301 can be started to rotate the central gear 305, and the central gear 305 drives the transmission gear 306 to rotate, thereby driving the outer gear 307 to rotate, and the outer gear 307 drives the first vertical shaft 309 to rotate. The first vertical shaft 309 is driven by the sleeve ring 310 and the vertical auxiliary shaft 312 to rotate the second vertical shaft 313, thereby rotating the test block clamped in the middle. The paint spray head rotates downwardly so that the paint is evenly distributed on the outside of the test block, ensuring that the side of the test block is evenly sprayed and sealed, and the rotation of the first pulley 202 drives the second pulley 401 to rotate, so that the second pulley 401 drives the worm gear set 402 to rotate, and the worm gear set 402 drives the pulley set 403 to rotate, thereby driving the driving gear 404 to rotate, and the rotation of the driving gear 404 drives the moving rack 405 to move inside the outer sleeve shaft 406, so that the moving rack 405 moves out from the inside of the outer sleeve shaft 406, and the movement of the moving rack 405 drives the hinge block 408 to move together, so that the hinge block 408 moves inside the limiting groove 411, and the movement of the hinge block 408 drives the half gear 407 and the extension rod 409 to move together, and because the end of the moving rack 405 is meshed with the half gear 407 and the hinge block 408 Due to the hinged connection with the half gear 407, when the extension rod 409 reaches the turning position of the limit groove 411, the flip door 410 will also turn, thereby dividing the two spaces inside the installation box 1, so that the test block can be sealed by the paint spraying under the paint spraying head while reducing the impact on the water tank assembly 5. When the paint spraying surface of the test block is dry, it can be rotated back.When the test block is flipped, it is in a vertical state and located at the bottom of the drain pipe 510, and the penetration test can be carried out. Whether the differential pressure on both sides of the test block needs to be increased is determined according to the thickness of the test block. If necessary, the handle 509 is shaken to make the handle 509 drive the side turbine 508 to rotate, and the side turbine 508 drives the threaded worm 507 to rotate, so that the limit threaded shaft 506 is lifted and lowered, and the lifting and lowering of the limit threaded shaft 506 drives the lifting frame 505 to lift and lower, so that the folded lifting frame 504 is unfolded, and the outer folding box body 501 is a folding structure, which will also unfold with the internal unfolding structure. The foldable box 501 is unfolded, thereby expanding the height of the foldable box 501 and increasing the internal volume. At this time, the water inside the foldable box 501 is filled, and the water level height is maintained during the experiment using a water level sensor. The control valve outside the drain pipe 510 is opened to conduct a permeation experiment. In the experiment, since the sides are sealed, the test block can only penetrate from top to bottom. The detection equipment below contacts the water to obtain the permeation time. The permeability of the test block can be calculated by cooperating with the pressure detection equipment installed at both ends of the test block and the thickness of the test block, thereby obtaining the permeability of the porous material in the building material.

The scope of the present application is defined by the appended claims and their equivalents.
