Description

Technical Field

[0001] This utility model belongs to the field of building inspection technology, and specifically relates to a building reinforced concrete inspection device. Background Technology

[0002] During the construction process, steel bars and concrete are used together to build the main structure of the building. Different types of buildings have different requirements for the strength of the reinforced concrete and the thickness of the protective layer. Therefore, the selected reinforced concrete needs to be tested before construction.

[0003] The existing reinforced concrete testing device consists of an operating table, a pressure testing device, and a power unit. By placing the reinforced concrete sample block to be tested on the operating table and turning on the power unit, the reinforced concrete can be tested under the action of the pressure device.

[0004] A testing device for reinforced concrete in construction, authorized by CN 222232217 U3, includes a base plate; a testing device is mounted on the base plate; a hydraulic cylinder is mounted at the center of the top of the top plate; a pressure plate is fixedly connected to the bottom end of the hydraulic rod; slots are formed on both sides of the top of the pressure plate; telescopic rods are mounted at both ends of the bottom of the clamping rod; limit rods are mounted on the opposite surface of the fixing block; a scale is fixedly connected to the top end face of the fixing block; a cleaning device is mounted on the base plate; the output shaft end of a small motor is connected to a lead screw; air nozzles are obliquely mounted on both sides of the bottom of the actuating rod; and a fan is mounted at one end of the top of the actuating rod. Through the combined action of the testing device and the cleaning device, pressure resistance testing and protective layer thickness testing can be performed simultaneously, improving the efficiency of the testing work and reducing the time spent on preliminary preparation.

[0005] Although the above-mentioned application can simultaneously detect the pressure and thickness of the concrete block to be tested, the installation of the thickness detection structure requires fixing to the pressure plate through a fixing plate, and both assembly and disassembly require manual intervention. It is impossible to automatically fix or loosen the thickness detection structure by raising and lowering the pressure plate, which greatly reduces the actual ease of assembly and disassembly of the thickness detection structure. Therefore, a building reinforced concrete testing device is needed. Utility Model Content

[0006] The purpose of this invention is to provide a testing device for reinforced concrete in buildings to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A reinforced concrete testing device for buildings includes a base, with a top plate fixed to the top of the base via columns on all four sides. A hydraulic cylinder is fixed to the center of the top of the top plate, with the telescopic end of the hydraulic cylinder penetrating the top plate and fixed to a pressure plate. A pressure detector is also fixed to the center of the top of the base. A linkage-fixed thickness measuring component is installed on the pressure plate.

[0009] Preferably, the linkage fixed thickness measuring component includes two symmetrically arranged grooves at the top of the pressure plate. The grooves have a convex cross-section, and each groove has a mounting plate with a convex cross-section that is movably inserted into it. T-shaped rulers are movably inserted into both ends of the mounting plates, and the bottom ends of the two T-shaped rulers on the same side are fixed to the same base plate.

[0010] Preferably, the top of the mounting plate has two symmetrically arranged slots, and the vertical cross-section of each slot is an isosceles trapezoidal structure.

[0011] Preferably, both sides of the mounting plate are provided with guide rails fixed to the top of the pressure plate, and the guide rails are movably sleeved on the outside of the insert rod with an isosceles trapezoidal vertical cross section.

[0012] Preferably, a transmission column is fixedly connected to the end of the insertion rod away from the slot, and the end of the transmission column away from the insertion rod is movably connected to the transmission channel opened on the Z-shaped transmission rod. The bottom end of the Z-shaped transmission rod is fixedly connected to the top end of the base, and the vertical cross section of the transmission channel is also Z-shaped.

[0013] Preferably, the inner width of the transmission channel is equal to the diameter of the transmission column.

[0014] Compared with the prior art, the building reinforced concrete testing device provided by this utility model has the following beneficial effects:

[0015] In this invention, when using the reinforced concrete testing device, the hydraulic cylinder is activated and pushes the pressure plate downward, simultaneously driving the four insertion rods downward. At the same time, the transmission column moves downward through the transmission channel in the Z-shaped transmission rod. Combined with the shape design of the transmission channel on the Z-shaped transmission rod, the insertion rods, guided by the guide rail, move towards the slot and insert, thus actively fixing the mounting plate. This allows the thickness measuring component to be actively fixed on the pressure plate as it descends, eliminating the need for manual intervention. Furthermore, after the pressure plate automatically rises to its reset height, the end of the insertion rod furthest from the transmission column is actively pulled out of the slot, achieving automatic loosening. In summary, the fixing or loosening of the mounting plate requires no manual intervention, greatly improving the convenience of mounting and dismounting the thickness measuring component from the pressure plate, saving time, and significantly increasing testing efficiency.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Example

[0025] Although the above application can simultaneously detect the pressure and thickness of the concrete block to be tested, the installation of the thickness detection structure requires fixing to the pressure plate 15 through a fixing plate, and both installation and disassembly require manual intervention. It is impossible to automatically fix or loosen the thickness detection structure by raising and lowering the pressure plate 15, which greatly reduces the actual ease of installation and disassembly of the thickness detection structure.

[0026] For this purpose, please refer to Figure 1-3This utility model provides a building reinforced concrete testing device, including: a base 1, with the same top plate 13 fixed to the top of the base 1 around the top perimeter by columns 12, a hydraulic cylinder 14 fixed to the center of the top of the top plate 13, the telescopic end of the hydraulic cylinder 14 penetrating the top plate 13 and fixed to a pressure plate 15, a pressure detector 11 fixed to the center of the top of the base 1, and a linkage fixed thickness measuring component 2 installed on the pressure plate 15.

[0027] Among them, the pressure detector 11 is a component in the prior art application, and everything is the same as in the prior art application, so it will not be described in detail.

[0028] Further as Figure 1-3 As shown, it is worth noting that, in order to enable the installation or disassembly of the thickness measuring structure to be achieved by raising and lowering the pressure plate 15 without manual intervention, a linkage-fixed thickness measuring component 2 is provided. This component includes two symmetrically arranged grooves 21 at the top of the pressure plate 15. The cross-section of each groove 21 is convex, and a mounting plate 22 with a convex cross-section is movably inserted into each groove 21. T-shaped rulers 23 are movably inserted into both ends of each mounting plate 22. The bottom ends of the two T-shaped rulers 23 on the same side are fixed to the same base plate 24. Two symmetrically arranged slots are provided at the top of the mounting plate 22. 25. The vertical cross-section of the slot 25 is an isosceles trapezoidal structure. The two sides of the mounting plate 22 are provided with guide rails 26 fixed to the top of the pressure plate 15. The guide rails 26 are movably sleeved on the outside of the insert rod 27 with an isosceles trapezoidal vertical cross-section. The end of the insert rod 27 away from the slot 25 is fixedly connected to a transmission column 28. The end of the transmission column 28 away from the insert rod 27 is movably connected to the transmission channel 210 opened on the Z-shaped transmission rod 29. The bottom end of the Z-shaped transmission rod 29 is fixedly connected to the top of the base 1. The vertical cross-section of the transmission channel 210 is also Z-shaped. The inner width of the transmission channel 210 is equal to the diameter of the transmission column 28.

[0029] The top of the guide rail 26 is movably fitted onto the bottom of the insertion rod 27 through a slot, so the vertical cross section of the slot is also an isosceles trapezoidal structure. An inclined section is provided in the transmission channel 210 near the top of its Z-shaped transmission rod 29. The inclined section is provided to change the position of the transmission column 28. As the pressure plate 15 moves down, the transmission column 28 moves down in the transmission channel 210. When passing through the inclined section, the insertion rod 27 is guided into the insertion slot 25, thereby fixing the mounting plate 22 on the pressure plate 15. The inner width of the transmission channel 210 is equal to the diameter of the transmission column 28 to prevent the insertion rod 27 from moving left and right and becoming unstable.

[0030] In summary: When using this reinforced concrete testing device, when the hydraulic cylinder 14 is activated and pushes the pressure plate 15 downward, it simultaneously moves the four insertion rods 27 downward, and at the same time moves the transmission column 28 downward in the transmission channel 210 opened in the Z-shaped transmission rod 29. Combined with the shape design of the transmission channel 210 on the Z-shaped transmission rod 29, the insertion rods 27 move towards the slots 25 under the auxiliary guidance of the guide rail 26 and are inserted, thereby achieving active fixation of the mounting plate 22. As the thickness measuring component descends with the pressure plate 15, it is actively fixed on the pressure plate 15 without manual intervention. In addition, after the pressure plate 15 automatically rises to the reset height, the end of the insertion rod 27 away from the transmission column 28 is actively pulled out of the slot 25, achieving the purpose of automatic loosening. In summary, the fixing or loosening of the mounting plate 22 does not require manual intervention, greatly improving the convenience of installing and removing the thickness measuring component from the pressure plate 15, saving installation and removal time, and greatly improving the efficiency of testing.
