[0040] The following is combined with Figure 1-11 The present invention is described in further detail.

[0041] like Figure 1-11 As shown, a material testing device for construction engineering includes a frame 1, a guide rail mechanism 2, a clamp mechanism 3, a pressure test mechanism 4 and a distance adjustment mechanism 5; the guide rail mechanism 2 is installed on the frame 1; there are two clamp mechanisms 3, and the two clamp mechanisms 3 are relatively matched on both sides of the guide rail mechanism 2; the pressure test mechanism 4 is detachably connected to the frame 1 and is located between the two clamp mechanisms 3; the distance adjustment mechanism 5 is installed on the frame 1, and the distance adjustment mechanism 5 is transmission-connected to the two clamp mechanisms 3 to drive the two clamp mechanisms 3 to synchronously approach the pressure test mechanism 4 or synchronously move away from the pressure test mechanism 4.

[0042] A material testing device for construction projects according to the present invention is mainly used for testing the structural strength of building boards, and can also be used for fixing building boards during the testing process, and cooperate with other testing equipment to perform multiple tests on the present invention; when the present invention tests the structural strength of building boards, it can test one building board, or it can test two different building boards at the same time, so as to form a comparison, which is convenient for intuitively observing the structural strength of different building boards; the two clamping mechanisms 3 inside it are used to support and clamp the building boards; after the building boards are installed, the distance adjusting mechanism 5 can be started, and the distance adjusting mechanism 5 controls the two clamping mechanisms 3 to slide on the guide rail mechanism 2, thereby controlling the building boards on the two clamping mechanisms 3 to move synchronously toward the pressure test mechanism 4, so as to press the building boards through the pressure test mechanism 4, and record the pressure at that time when the building boards are deformed or broken, thereby testing the structural strength of the building boards.

[0043] The guide rail mechanism 2 includes an I-shaped guide rail 201, a movable bracket 202, a transmission rod 203, a displacement seat 204, a first lead screw 205 and a first motor 206; the I-shaped guide rail 201 is provided with two, and the two I-shaped guide rails 201 are slidably fitted on the top surface of the frame 1, and the two I-shaped guide rails 201 are fixedly connected one by one with the two movable brackets 202, and the two movable brackets 202 slide relatively in the side slides on both sides of the frame 1; one end of the two movable brackets 202 is rotatably connected one by one with one end of the two transmission rods 203, and the other ends of the two transmission rods 203 rotate relatively at both ends of the displacement seat 204; the displacement seat 204 is threadedly fitted in the middle of the first lead screw 205, and the first lead screw 205 rotates on the bottom surface of the frame 1 through the lead screw support; one end of the first lead screw 205 is transmission-connected to the output shaft of the first motor 206 mounted on the frame 1; the clamp mechanism 3 slides on the two I-shaped guide rails 201.

[0044] The guide rail mechanism 2 is an adjustable guide rail. When in use, the distance between the two I-shaped guide rails 201 can be adjusted according to the size of the building board required to be clamped by the clamp mechanism 3. During adjustment, the first motor 206 is powered on and started. After the first motor 206 is started, it can drive the first screw 205 to rotate. When the first screw 205 rotates, it can change its contact position with the displacement seat 204, thereby pushing or pulling one end of the two transmission rods 203 to move through the displacement seat 204, and the other ends of the two transmission rods 203 drive the two movable brackets 202 to slide toward or away from each other in the side slides on both sides of the frame 1, thereby changing the distance between the two I-shaped guide rails 201.

[0045] The pitch adjustment mechanism 5 includes a second motor 501 and a bidirectional screw 502. The output shaft of the second motor 501, mounted on the frame 1, is connected to one end of the bidirectional screw 502. The bidirectional screw 502 has a left-handed thread at one end and a right-handed thread at the other end. The two ends of the bidirectional screw 502 are connected to the two oppositely disposed clamp mechanisms 3 by threaded connection. After the second motor 501 is started, it can drive the bidirectional screw 502 to rotate. Because the bidirectional screw 502 has a left-handed thread at one end and a right-handed thread at the other end, the rotation of the bidirectional screw 502 can drive the two clamp mechanisms 3 to slide toward or away from each other on the two I-shaped guide rails 201 of the guide rail mechanism 2, thereby driving the two building boards to move synchronously toward the compression test mechanism 4, so that the building boards can pass the top pressure test of the compression test mechanism 4.

[0046] The clamping mechanism 3 includes a U-shaped clamping groove frame 301, a short shaft 302, a slide seat 303 and a telescopic rod assembly 304; there are two slide seats 303, the two slide seats 303 are slidably matched with the two I-shaped guide rails 201, and the two slide seats 303 are connected by the telescopic rod assembly 304; each slide seat 303 is rotatably connected to a short shaft 302, and the tops of the two short shafts 302 are fixed to the two U-shaped clamping groove frames 301 one by one, and the side surfaces of the two U-shaped clamping groove frames 301 are threadedly matched to connect the upper and lower multiple first push rods; the middle part of the telescopic rod assembly 304 is threadedly matched on the bidirectional screw 502.

[0047] The U-shaped clamping groove frame 301 in the clamping mechanism 3 is used to support the building board. One side surface of the U-shaped clamping groove frame 301 is threadedly connected to the upper and lower multiple first push rods, and the multiple first push rods are used to press and limit one side of the building board, so that the building board has better stability during testing; there are two U-shaped clamping groove frames 301, and the bottoms of the two U-shaped clamping groove frames 301 are rotatably connected to the slide seat 303 through a short shaft 302, so that they can rotate relative to each other to a certain extent during testing, thereby reducing the damage to the contact position between the U-shaped clamping groove frame 301 and the building board when the pressure testing mechanism 4 performs pressure testing on the building board, affecting the testing effect; the overall length of the telescopic rod assembly 304 can be adjusted as the distance between the two slide seats 303 changes. The setting of the telescopic rod assembly 304 enables the two slide seats 303 to move under the drive of the two I-shaped guide rails 201 of the guide rail mechanism 2, thereby adjusting the distance between the two U-shaped clamping groove frames 301, so as to more stably support building boards of different sizes.

[0048] The telescopic rod assembly 304 includes a central slide 304a, a central sleeve 304b, a telescopic slide 304c and a side support 304d; the central slide 304a is threadedly engaged on the bidirectional screw 502, the middle part of the central sleeve 304b is rotatably engaged in the transverse through hole of the central slide 304a, and the two ends of the central sleeve 304b are respectively slidably engaged with a telescopic slide 304c, and the telescopic slide 304c is provided with a guide groove, which slides with the guide ridge in the central sleeve 304b; the outer ends of the two telescopic slides 304c are rotatably connected to the side supports 304d, and the two side supports 304d are fixedly connected to the two slide groove seats 303 one by one.

[0049] The central slide 304a inside the telescopic rod assembly 304 can slide on the frame 1 under the drive of the bidirectional screw 502, thereby driving the telescopic rod assembly 304 to move as a whole. The telescopic rod assembly 304 drives the entire clamp mechanism 3 to slide on the two I-shaped guide rails 201. When the distance between the two I-shaped guide rails 201 is adjusted, the two slide seats 303 can drive the two telescopic slide rods 304c to slide in the central sleeve 304b.

[0050] The two telescopic slide rods 304c are both worm structures. The two telescopic slide rods 304c are engaged one by one with the worm wheels 305 fixed on the two short shafts 302 to drive the two worm wheels 305 to rotate in different clockwise directions; the outer end of one telescopic slide rod 304c is connected to the output shaft of the third motor 306.

[0051] Since the telescopic slide rod 304c is provided with a guide groove, the guide groove slides with the guide ridge in the central sleeve 304b, thereby ensuring that the telescopic slide rod 304c and the central sleeve 304b can rotate synchronously. After the third motor 306 is powered on and started, it can drive one telescopic slide rod 304c to rotate. When the telescopic slide rod 304c rotates, it can drive the central sleeve 304b and the other telescopic slide rod 304c to rotate. The two telescopic slide rods 304c are both worm structures. When the two telescopic slide rods 304c rotate, they can drive the two worm wheels 305 to rotate in different clockwise directions, so that the building materials installed in the two U-shaped clamping groove frames 301 can be bent, such as bending steel pipes, which enriches the detection means of the present invention and improves the detection effect.

[0052] The compression test mechanism 4 includes a gate-shaped bracket 401, a power assembly 402, a transmission assembly 403, and an impact assembly 404; the two ends of the gate-shaped bracket 401 are connected to the two ends of the frame 1 by bolts; the power assembly 402 installed on the frame 1 is transmission-connected to the transmission assembly 403, and the transmission assembly 403 is transmission-connected to two impact assemblies 404 connected to the gate-shaped bracket 401.

[0053] The impact assembly 404 includes an impact plate 404a, a horizontal sliding shaft 404b, a linkage plate 404c, a guide seat plate 404d and an inclined link 404e; there are multiple horizontal sliding shafts 404b, the middle parts of the multiple horizontal sliding shafts 404b are slidably fitted on the guide seat plate 404d, the guide seat plate 404d is fixed on the door-shaped bracket 401, and the inner and outer ends of the multiple horizontal sliding shafts 404b are respectively detachably connected to the linkage plate 404c and the impact plate 404a; the linkage plate 404c is rotatably connected to one end of the inclined link 404e, and the other end of the inclined link 404e is rotatably connected to the transmission assembly 403; a pressure sensor is provided on the outer surface of the impact plate 404a.

[0054] After the power component 402 is started, it can drive the transmission component 403 to move. When the transmission component 403 moves, it can drive one end of the tilting link 404e to move in the up and down directions. The other end of the tilting link 404e pushes or pulls the linkage plate 404c to move. The linkage plate 404c drives multiple horizontal sliding shafts 404b to slide on the guide seat plate 404d, thereby driving the impact plate 404a through the multiple horizontal sliding shafts 404b to perform impact tests on the building panels.

[0055] The transmission assembly 403 includes a driven friction disc 403a, a wheel shaft 403b, a rotating gear 403c, a rack 403d, upper and lower slides 403e, a vertical support shaft 403f, a top plate 403g, a tension spring 403h and a limit screw 403i; the driven friction disc 403a is connected to the power assembly 402 in a transmission manner, the driven friction disc 403a and the rotating gear 403c are respectively fixed at both ends of the wheel shaft 403b, the wheel shaft 403b rotates on the bearing frame, and the bearing frame is fixed on the door-shaped bracket 401; the rotating gear 403c engages with the transmission connection The rack 403d is connected, and the top end of the rack 403d is fixed on the upper and lower slides 403e. The upper and lower slides 403e slide in the middle of the two vertical support shafts 403f. The bottom ends of the two vertical support shafts 403f are fixed on the door-shaped bracket 401. The upper and lower slides 403e are fixedly connected to the door-shaped bracket 401 through multiple tension springs 403h. The top ends of the two vertical support shafts 403f are fixedly connected to the top plate 403g. The threads on the top plate 403g cooperate with the limit screw 403i to limit the top ends of the upper and lower slides 403e through the limit screw 403i. After the power assembly 402 is started, when the power assembly 402 contacts the driven friction disc 403a, the driven friction disc 403a can be driven to rotate. When the driven friction disc 403a rotates, the rotating gear 403c can be driven to rotate through the wheel shaft 403b. The rotating gear 403c drives the rack 403d to move by meshing with the rack 403d. When the rack 403d moves upward, it can drive the upper and lower slides 403e to slide upward on the vertical support shaft 403f and stretch the tension spring 403h. When a is separated, the upper and lower slides 403e move downward under the elastic force of the tension spring 403h, thereby driving one end of the inclined link 404e to move downward, and finally controlling the impact plate 404a to perform an impact test on the building board, which is convenient for multiple impact tests on the building board to test its impact resistance; the limiting screw 403i is used to limit the height of the upper and lower slides 403e, and is suitable for the clamp mechanism 3 to drive the building board to move toward the pressure test mechanism 4, and the pressure test mechanism 4 is used in a stationary state to limit the position of the impact plate 404a.

[0056] The power assembly 402 includes a power motor 402a, a drive shaft 402b, an irregular friction wheel 402c and an adjusting screw 402d; the output shaft of the power motor 402a is connected to one end of the drive shaft 402b, and the drive shaft 402b is slidably fitted with the irregular friction wheel 402c, and the irregular friction wheel 402c is intermittently friction-drivenly connected to the driven friction disk 403a; one end of the adjusting screw 402d rotates on the protrusion at the other end of the drive shaft 402b, and the other end of the adjusting screw 402d is threadedly fitted on the irregular friction wheel 402c to drive the irregular friction wheel 402c to slide on the drive shaft 402b; a tensioning spring is sleeved on the adjusting screw 402d, and the tensioning spring is located between the irregular friction wheel 402c and the protrusion. After the power motor 402a is powered on and started, it can drive the drive shaft 402b to rotate. The rotation of the drive shaft 402b drives the irregular friction wheel 402c to rotate. When the irregular friction wheel 402c rotates to contact the driven friction disk 403a, the vertical friction transmission drives the driven friction disk 403a to rotate. When the irregular friction wheel 402c is separated from the driven friction disk 403a, the transmission stops; the contact position of the irregular friction wheel 402c and the driven friction disk 403a can be adjusted by rotating the adjusting screw 402d to change the transmission ratio, change the stretching amplitude of the tension spring 403h, and finally change the impact force of the impact plate 404a to meet the detection requirements of different building panels.

[0057] The method for using the construction material detection device comprises the following steps:

[0058] Step 1: Adjust the distance between the two U-shaped clamping groove frames 301 in the clamp mechanism 3 according to the size of the building board to be tested;

[0059] Step 2: Install the building board to be tested on the fixture mechanism 3;

[0060] Step 3: Control the clamp mechanism 3 to slide on the guide rail mechanism 2 through the distance adjustment mechanism 5 to adjust the relative position of the building board installed in the clamp mechanism 3 and the compression test mechanism 4;

[0061] Step 4: Start the compression test mechanism 4 to press the building board installed on the clamp mechanism 3 to detect the pressure required for the building board to deform, thereby detecting whether the building board meets the pre-set quality standards.

[0062] Principle: A material testing device for construction engineering of the present invention is mainly used for testing the structural strength of building boards, and can also be used for fixing building boards during the testing process, and cooperate with other testing equipment to perform multiple tests on the present invention; when the present invention tests the structural strength of building boards, it can test one building board, or it can test two different building boards at the same time, so as to form a comparison, which is convenient for intuitively observing the structural strength of different building boards; the two clamping mechanisms 3 inside it are used to support and clamp the building boards; after the building boards are installed, the distance adjusting mechanism 5 can be started, and the distance adjusting mechanism 5 controls the two clamping mechanisms 3 to slide on the guide rail mechanism 2, thereby controlling the building boards on the two clamping mechanisms 3 to move synchronously toward the pressure test mechanism 4, so as to press the building boards through the pressure test mechanism 4, and record the pressure at that time when the building boards are deformed or broken, thereby testing the structural strength of the building boards.
