Description

Technical Field

[0001] The present invention relates to the field of glass strength detection, and in particular to a glass curtain wall detection device for engineering supervision. Background Art

[0002] Engineering supervision refers to a professional service activity in which a supervision unit with relevant qualifications is entrusted by Party A to monitor the construction of Party B's project on behalf of Party A in accordance with the project construction documents approved by the state, relevant laws and regulations on project construction, the project construction supervision contract and other project construction contracts. Engineering supervision is a paid engineering consulting service entrusted by Party A. The main basis for supervision is laws, regulations, technical standards, relevant contracts and documents. The principles of supervision are to abide by the law, be honest, fair and scientific. The purpose of supervision is to ensure the quality and safety of project construction, improve the level of project construction, and give full play to the investment benefits. Its responsibilities include investment control, construction period control, project quality control, safety control, information management, project construction contract management, and coordination of the working relationships between relevant units. Among them, in the work of controlling project quality, engineering supervision needs to use detection devices for engineering supervision to detect building materials, construction quality, etc.

[0003] When detecting building materials, some indicators of the glass curtain wall need to be detected. The main detection indicators include materials, structural bearing capacity, heat conduction, tensile strength and shear strength, etc. These indicators are analyzed to ensure the safety of the curtain wall.

[0004] At present, for the detection device of the structural bearing capacity of the glass curtain wall, the sample of the glass curtain wall to be detected is tested by applying an external force, and the data obtained is used to evaluate the level of the structural bearing capacity of the glass curtain wall. In addition to being able to change the external force to detect the glass curtain wall, the existing glass curtain wall detection device is not convenient to simulate the situation of the glass curtain wall under different bearing surfaces and different stress surfaces, so that the evaluation data of the glass curtain wall strength is not comprehensive enough.

[0005] Existing patent: CN117347181B discloses a glass curtain wall detection device, and the technical solution is: a glass curtain wall detection device, including two support legs, etc.; a hydraulic cylinder is fixedly connected between the two support bent columns, and a strip-shaped extrusion mechanism is arranged on the two support bent columns. The strip-shaped extrusion mechanism is used for extruding and testing the glass curtain wall sample, and a pull plate mechanism is arranged on the two support legs.

[0006] In the above solution, when the telescopic shaft of the hydraulic cylinder moves downward, it will drive the sliding bracket, the strip-shaped extrusion rod and the sleeve long rod to move downward together, so that the extrusion force of the strip-shaped extrusion rod on the glass curtain wall gradually increases.

[0007] However, the test results are still relatively single, and it is impossible to fully obtain the test data of the curtain wall types existing on the market, especially the data of all-glass curtain walls or glass keel curtain walls. Summary of the Invention

[0008] Aiming at the deficiencies of the prior art, the present invention provides a glass curtain wall detection device for engineering supervision, which solves the problems raised in the above background technology.

[0009] To achieve the above objectives, the present invention is realized through the following technical solutions: A glass curtain wall detection device for engineering supervision includes a test base, a stepped platform, and a test platform.

When the retaining pin is stuck below the snap ring, the retaining pin fixes the sleeve and the displacement plate;

[0013] The upper end of the column core is inside the sleeve. A piston is fixedly installed at the upper end of the column core, and the piston cooperates with the inner wall of the sleeve. A spring is fixedly sleeved outside the end of the column core at the bottom of the sleeve, and the upper end of the spring is fixed to the bottom of the column core. When the column core moves upward, the piston moves upward along the inner cavity of the sleeve, and at this time the spring is compressed. The pressure rod is fixed to the bottom end of the column core. A protective shell is fixedly sleeved at the bottom of the outer end of the sleeve, and the pressure rod and the column core can both pass through the protective shell.

[0014] Preferably, the displacement platform includes two horizontal bars and two vertical bars, the two horizontal bars are arranged in parallel, the angle between the horizontal bars and the vertical bars is ninety degrees, the vertical bars are arranged below the horizontal bars, and the bottom of the vertical bars are installed with stepping platforms A, and the stepping platform A cooperates with the test platform to move laterally, and the intersection of the horizontal bars and the vertical bars is installed with stepping platforms B, and the stepping platform B slides in cooperation with the horizontal bars, and the bottom of the stepping platform B slides in cooperation with the vertical bars, and the stepping platform A and the stepping platform B can adjust the size of the rectangular area between the horizontal bars and the vertical bars under the action of electric drive.

[0015] Preferably, the displacement platform also includes a short support rod and a long support rod, and a plurality of array-distributed sockets are provided on the horizontal rod and the vertical rod. The short support rod can be inserted into the socket of the horizontal rod, and the long support rod can be inserted into the socket of the vertical rod. After the two are inserted, the upper ends are at the same height. The upper ends of the long support rod and the short support rod are provided with a central screw hole and a plurality of positioning screw holes distributed around the central screw hole, and the positioning screw holes are used to fix the glass keel.

[0016] Preferably, the displacement platform further comprises a glass fixer, which can be installed on the central screw hole and is used to fix the corners of the glass.

[0017] Preferably, the pneumatic pressure assembly comprises a cylinder, the cylinder is fixed on the test base platform by a support plate, and the output end of the cylinder is fixed to the sliding sleeve.

[0018] Preferably, the hydraulic pressure assembly includes a hydraulic cylinder, which is fixed to the test platform by a support plate, and the output end of the hydraulic cylinder corresponds to the upper side of the sliding sleeve.

[0019] Preferably, the upper ends of the short support rod and the long support rod are provided with a protruding round table, and the lower ends are provided with a boss on the outside, the boss is used to limit the depth of insertion into the socket, and the center screw hole and the positioning screw hole are both provided on the round table.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The glass curtain wall detection device for project supervision can change the rectangular area enclosed between the cross bar and the longitudinal bar according to the glass area to be tested by setting a displacement platform. After determining the area, when testing the glass with framed keels, long support rods and short support rods can be inserted into appropriate jacks to support the glass keels. The aluminum alloy keels can be fixed in the positioning screw holes with screws. At this time, when testing the glass, the glass belongs to the fixed outer circle. When testing the pure glass curtain wall structure, the glass fixator is installed on the long support rods or short support rods distributed at the four corners of the rectangle. The glass fixator can fix the four corners of the glass. At this time, when conducting the glass compression test, the glass belongs to the four fixed points. Thus, there are two special fixing forms, and when detecting the glass curtain wall, various different data can be obtained, and the detection result is more accurate.

[0022] 2. The glass curtain wall detection device for project supervision can install a matrix-distributed dot-type pressure measuring mechanism on the through holes of the displacement plate according to the size of the rectangle formed by the combination of the displacement platforms. The matrix-distributed dot-type pressure measuring mechanism corresponds to the glass to be tested. When the hydraulic pressure application component applies pressure, the displacement plate can drive all the dot-type pressure measuring mechanisms to fit against the glass. By filling hydraulic oil into the envelope, the column core cannot be compressed, so the pressure rod cannot move into the envelope. At this time, the envelope and the pressure rod are integral and fixed, and a point pressure can be applied to the glass. When the hydraulic oil inside the envelope is extracted, the spring can be compressed, and at this time, the pressure rod cannot apply pressure to the glass. Thus, by filling or extracting the hydraulic oil in different areas of the envelope, it can be ensured that the dot-type pressure measuring mechanisms at different positions can perform tests or stop working, so that multiple groups of test data can be obtained at one time when testing the glass, and the deformation data at each position can be tested in one clamping.

[0023] 3. The glass curtain wall detection device for project supervision can set a pneumatic pressure application component and a hydraulic pressure application component. When applying pressure to the glass, the pressure is mainly applied by the hydraulic pressure application component. Under the action of high-pressure gas, the pneumatic pressure application component can quickly drive the displacement plate with the dot-type pressure measuring mechanism to approach the glass. Since the displacement plate is not directly connected to the hydraulic pressure application component, the instantaneous contact between the dot-type pressure measuring mechanism and the glass can be tested, and the change of the glass curtain wall under impact at different points in the real environment can be tested. It can also be continuously impacted. Combined with the intermittent operation of the dot-type pressure measuring mechanisms at different positions, the impact conditions of multiple points on a piece of glass can be tested.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] As Figures 1-9 shown, a glass curtain wall detection device for engineering supervision includes a test base 1, a stepped platform 2, and a test platform 3. The stepped platform 2 and the test platform 3 are both fixedly installed on the test base 1, and the test platform 3 is at the uppermost position. It also includes a pneumatic pressure application component 4 and a hydraulic pressure application component 5. There are two of both the pneumatic pressure application component 4 and the hydraulic pressure application component 5, and they are respectively fixed at the four corners of the test base 1. The pneumatic pressure application component 4 and the hydraulic pressure application component 5 are arranged alternately;

[0039] It includes a detection component 6, which is suspended above the test platform 3 and includes a displacement platform 7, which is arranged on the test platform 3 and corresponds to be below the detection component 6;

[0040] The detection component 6 includes a displacement plate 601 and sliding rods 602. There are four sliding rods 602, and their bottom ends are respectively fixed to the four corners of the upper surface of the stepped platform 2. The displacement plate 601 is between the four sliding rods 602. Four corners of the displacement plate 601 are respectively slidably connected to the sliding rods 602 by sliding sleeves 603. The output end of the pneumatic pressure application component 4 is fixed to the sliding sleeves 603 at two diagonal corners, and the output end of the hydraulic pressure application component 5 corresponds to be above the sliding sleeves 603 at the other two diagonal corners. The displacement plate 601 is provided with through holes 604 distributed in a matrix, and the through holes 604 penetrate the displacement plate 601 downward; it also includes a dot matrix pressure measurement mechanism 605, which passes through the through holes 604 from bottom to top and is fixed to the displacement plate 601 by a snap pin 606 above.

[0041] The wiring harness, oil pipes, and air pipes of the device are all installed in the test base 1. A processor and an integrated circuit board are also installed inside the test base 1. When in use, the test base 1 is installed on an existing device bracket, and an air compressor and an oil pump need to be set up externally for pipeline cooperation.

[0042] The displacement plate 601 is a rectangular plate, and a frame-type reinforcement is welded above it. The reinforcement is a U-shaped metal beam, and the reinforcement is connected to the sliding sleeve 603. The force received by the sliding sleeve 603 itself can be transmitted to the displacement plate 601 through the reinforcement. The sliding sleeve 603 is in sliding fit with the sliding rod 602, and lubricating oil is applied between the two. Multiple dot matrix pressure measuring mechanisms 605 are provided, and the redundant ones are placed in the storage box. When actually testing the glass, the dot matrix pressure measuring mechanism 605 is installed according to the size of the glass.

[0043] The dot matrix pressure measuring mechanism 605 includes an envelope 6051, a column core 6052, and a pressure rod 6053. A bottom ring 6054 is fixedly installed on the outer ring of the envelope 6051. The envelope 6051 can pass through the through hole 604, and the bottom ring 6054 is blocked. The inside of the envelope 6051 is a hollow structure. An oil injection pipe 6055 is installed at the upper end of the envelope 6051. A snap ring 6056 is fixedly installed outside the oil injection pipe 6055. When the snap pin 606 is stuck below the snap ring 6056, the snap pin 606 fixes the envelope 6051 and the displacement plate 601.

[0044] The upper end of the column core 6052 is inside the envelope 6051. A piston 6057 is fixedly installed at the upper end of the column core 6052. The piston 6057 cooperates with the inner wall of the envelope 6051. A spring 6058 is fixedly sleeved outside the end of the column core 6052 at the bottom of the envelope 6051. The upper end of the spring 6058 is fixed to the bottom of the column core 6052. When the column core 6052 moves upward, the piston 6057 moves upward along the inner cavity of the envelope 6051. At this time, the spring 6058 is compressed. The pressure rod 6053 is fixed to the bottom end of the column core 6052. A protective shell 6059 is fixedly sleeved at the bottom of the outer end of the envelope 6051. Both the pressure rod 6053 and the column core 6052 can pass through the protective shell 6059.

[0045] The outer diameter of the envelope 6051 matches the through hole 604. The oil injection pipe 6055 is above the displacement plate 601. A pipeline quick connector is installed on each oil injection pipe 6055, and a solenoid valve is provided inside the high-pressure oil circuit connected to the oil injection pipe 6055. The circuit of each solenoid valve is connected to the circuit board inside the test base 1. The solenoid valve is opened and closed according to the electrical signal emitted by the circuit board. Thus, it can be realized to control whether there is hydraulic oil inside each envelope 6051 according to the internal system. An air valve is also installed on each envelope 6051. The air valve can keep the pressure inside the envelope 6051 constant when injecting or pumping oil. However, the air valve is a single-medium valve, and the hydraulic oil cannot pass through the air valve.

[0046] The variable-position platform 7 includes two cross bars 701 and two longitudinal bars 702. The two cross bars 701 are arranged in parallel, and the two longitudinal bars 702 are arranged in parallel. The included angle between the cross bar 701 and the longitudinal bar 702 is ninety degrees. The longitudinal bar 702 is arranged below the cross bar 701. Stepping platforms A703 are installed at the bottoms of the longitudinal bars 702. The stepping platforms A703 cooperate with the test platform 3 for lateral movement. Stepping platforms B704 are installed at the intersections of the cross bar 701 and the longitudinal bar 702. The stepping platforms B704 cooperate with the cross bar 701 for sliding, and the bottoms of the stepping platforms B704 also cooperate with the longitudinal bar 702 for sliding. The stepping platforms A703 and the stepping platforms B704 can adjust the size of the rectangular area between the cross bar 701 and the longitudinal bar 702 under the action of electric drive.

[0047] The stepping platforms A703 and the stepping platforms B704 have basically the same structure, and a servo motor and a small gear are installed inside. The servo motor is controlled by a servo drive board. The stepping platform A703 can move forward along the test platform 3 under the action of the servo motor. Multiple chutes are provided at the mating part of the test platform 3 with it. Different from this, the stepping platform B704 is provided with two servo motors, and the two servo motors act on the cross bar 701 and the longitudinal bar 702 respectively. Thus, the longitudinal bar 702 can not only slide along the direction of the cross bar 701, but also slide along its own axis. Chutes are provided at the mating parts of the cross bar 701 and the longitudinal bar 702 with the servo motors, and smaller tooth grooves are provided in the chutes, or rubber rollers can also be driven by the servo motor to move.

[0048] In one of the embodiments, as Figure 3 、 5 shown, the variable-position platform 7 further includes short support rods 705 and long support rods 706. A number of arrayed jacks 707 are opened on both the cross bar 701 and the longitudinal bar 702. The short support rods 705 can be inserted into the jacks 707 of the cross bar 701, and the long support rods 706 can be inserted into the jacks 707 of the longitudinal bar 702. After they are inserted, their upper ends are at the same height. Central screw holes 708 and a plurality of positioning screw holes 709 distributed around the central screw hole 708 are provided at the upper ends of the long support rods 706 and the short support rods 705. The positioning screw holes 709 are used to fix the glass keel.

[0049] A number of short support rods 705 and long support rods 706 are also provided in a set of equipment. The quantity is selected according to the actual use requirements. When they are inserted into the inside of the jacks 707, the insertion depth is sufficient and there will be no shaking, and they can be used to fix the aluminum alloy outer frame of the glass.

[0050] In another embodiment, as Figure 4 shown, the variable-position platform 7 further includes a glass fixer 710. The glass fixer 710 can be installed on the central screw hole 708 and is used to fix the corners of the glass.

[0051] The glass fixator 710 is used to fix the four corner positions of the glass, which is different from the form of fixing the outer frame of the glass in terms of testing.

[0052] The pneumatic pressing assembly 4 includes a cylinder 401. The cylinder 401 is fixed on the test base 1 by a support plate, and the output end of the cylinder 401 is fixed to the sliding sleeve 603.

[0053] The hydraulic pressing assembly 5 includes a hydraulic cylinder 501. The hydraulic cylinder 501 is fixed on the test base 1 by a support plate, and the output end of the hydraulic cylinder 501 corresponds to the upper part of the sliding sleeve 603.

[0054] Both the upper ends of the short support rod 705 and the long support rod 706 are provided with protruding frustums, and the outer parts of the lower ends are provided with bosses. The bosses are used to limit the insertion depth into the jack 707. The central screw hole 708 and the positioning screw hole 709 are both arranged on the frustum.

[0055] The frustum plays a supporting role, and the boss plays a limiting role.

[0056] During use, first, by operating the stepping platform A 703 and the stepping platform B 704, the rectangular area enclosed between the cross bar 701 and the longitudinal bar 702 can be changed according to the area of the glass to be tested. After determining the area, when testing the glass with a framed keel, the long support rod 706 and the short support rod 705 can be inserted into the appropriate jacks 707. The long support rod 706 and the short support rod 705 form a rectangle to support the glass keel. The aluminum alloy keel can be fixed in the positioning screw hole 709 with screws. At this time, when testing the glass, the glass belongs to the fixed outer circle. When testing a pure glass curtain wall structure, the glass fixator 710 is installed on the long support rod 706 or the short support rod 705 distributed at the four corners of the rectangle, and the glass fixator 710 is installed in the central screw hole 708 with a large bolt. The glass fixator 710 can fix the four corners of the glass. At this time, when conducting the glass compression test again, the glass belongs to the four fixed points;

[0057] After the fixation is completed, according to the rectangular size of the displacement platform 7 combination, the matrix-distributed dot matrix pressure measuring mechanism 605 is installed on the through hole 604 of the displacement plate 601. The installation is very convenient. The cover 6051 is inserted into the through hole 604 from bottom to top, and then the cover 6051 is fixed with the bayonet 606. The matrix-distributed dot matrix pressure measuring mechanism 605 is placed against the glass to be tested. When the hydraulic pressure component 5 applies pressure, the displacement plate 601 can bring all the dot matrix pressure measuring mechanisms 605 to fit the glass. By filling the cover 6051 with liquid, the pressure is reduced. Hydraulic oil, the column core 6052 cannot be compressed, so the pressure rod 6053 cannot move into the envelope 6051. At this time, the envelope 6051 and the pressure rod 6053 are fixed as a whole, and a pressure of one point can be applied to the glass. When the hydraulic oil in the envelope 6051 is extracted, the spring 6058 can be compressed. At this time, the pressure rod 6053 cannot apply pressure to the glass. Therefore, according to the filling or extraction of hydraulic oil in different areas of the envelope 6051, it can be ensured that the dot matrix pressure measuring mechanism 605 at different positions can be tested or not work;

[0058] Two different test forms: when applying pressure to the glass, the pressure is mainly applied by the hydraulic pressure component 5, and the pneumatic pressure component 4 can, under the action of high-pressure gas, make the displacement plate 601 quickly bring the dot matrix pressure measuring mechanism 605 close to the glass, and the displacement plate 601 is not directly connected to the hydraulic pressure component 5, so the instantaneous contact between the dot matrix pressure measuring mechanism 605 and the glass can be tested. The pneumatic pressure component 4 is used alone, and the pneumatic pressure component 4 cooperates with the hydraulic pressure component 5 when it is in use. The changes in the impact of different points on the glass curtain wall in a real environment can be tested, and continuous impact can be performed. Combined with the intermittent operation of the dot matrix pressure measuring mechanism 605 at different positions, the impact of multiple points on a piece of glass can be tested.

[0059] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0060] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on what can be achieved by those of ordinary skill in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
