Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a steel structure strength testing device for building engineering. Background Technology
[0002] In modern architecture, steel structure is a common structural component. Steel structure is mainly composed of steel components connected together. During the construction process, due to changes in the weight of the building, the steel structure needs to have sufficient strength to overcome the influence of the weight of the building materials.
[0003] In the current construction process, in order to ensure the stability of steel structures, it is necessary to conduct strength tests on the steel structure components before the steel structure building is erected. The current strength testing method mainly relies on strength testing machines. When fixing the workpiece to be tested, the strength testing machine mainly relies on relative clamping. However, this clamping method has no limit in the other two horizontal directions because the force direction is bidirectional. Therefore, during the relative movement of the jaws, the end of the workpiece is prone to skew due to the lack of sufficient limit on both sides, resulting in inaccurate test results. In view of this, this case was developed through in-depth research on the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides an implementation scheme: In modern steel structure buildings, steel structures are common structural components. Due to the large stress on steel components, the strength requirements for steel structure components are high. At present, the strength testing of steel structure components mainly relies on strength testing machines. At present, strength testing machines mainly rely on clamps to fix the workpiece. However, due to the method of clamping on both sides, the steel component may move along the direction of the clamping gap during the test due to stress issues, causing the steel component to move and resulting in inaccurate test results.
[0021] To address the aforementioned issues, this application discloses a steel structure strength testing device for building engineering, comprising a testing frame 1 and a main unit. The testing frame 1 is connected to the main unit, which is an integrated electrical system for the tested structure. The main unit uses a computer as its core to collect data from various sensors used in the testing. A hydraulic control pump station 2 is installed at the bottom of the testing frame 1 to control the movement of various components. A testing platform 3 is installed on the upper part of the testing frame 1, which is the device for testing the structural strength of steel components. A guide lifting frame 4 is installed on the testing platform 3, and a pair of sliding guide rails 5 are installed on both sides of the guide lifting frame 4. The lifting and lowering of the testing device can be controlled through the pair of sliding guide rails 5, thereby realizing the lifting and lowering movement during the testing process.
[0022] According to the instruction manual Figure 1-3 It can be seen that a lifting control seat 6 is assembled between the pair of sliding guide rails 5, and a clamping guide rail 7 is provided on the lifting control seat 6. A pair of clamping seats 8 are assembled on the clamping guide rail 7, and the relative movement of the pair of clamping seats 8 is controlled by a pair of clamping cylinders 9.
[0023] In the specific implementation process, the lifting control seat 6 serves as the fixed base for the end of the workpiece. A pair of clamping cylinders 9 can control the relative movement of a pair of clamping seats 8. The clamping guide rail 7 controls and guides the pair of clamping seats 8. Through the relative movement of the pair of clamping seats 8, the pair of clamping seats 8 clamp the end of the workpiece.
[0024] Then, according to the instruction manual attached Figure 1-3It can be seen that the pair of clamping cylinders 9 are assembled on the lower part of the clamping guide rail 7. A pair of clamping control blocks 10 are connected to the telescopic ends of the pair of clamping cylinders 9. The pair of clamping control blocks 10 are connected to a pair of clamping seats 8. The telescopic ends of the pair of clamping cylinders 9 can adjust the telescopic movement of the pair of clamping control blocks 10, thereby using the pair of clamping control blocks 10 to drive the pair of clamping seats 8 to move, and using the pair of clamping seats 8 to clamp the two sides of the workpiece to be inspected.
[0025] To further limit the other two sides of the workpiece, two pairs of insertion slots 11 are provided on the opposite wall surfaces of a pair of clamping seats 8. A pair of fixing plates 12 are inserted into the two pairs of insertion slots 11. A pair of clamping fixing bolts 13 are provided on the pair of fixing plates 12. The pair of fixing plates 12 are arranged on the empty sides of the workpiece to be inspected. By using the clamping fixing bolts 13 on the fixing plates 12 to engage with the threads of the fixing plates 12, the feed amount of the clamping fixing bolts 13 can be adjusted. Then, by using the head end of the clamping fixing bolts 13 to contact the outer side of the workpiece, the limiting effect of the empty sides of the workpiece can be achieved.
[0026] As a preferred option, furthermore, a pair of clamping seats 8 are separately connected to a pair of clamping control blocks 10 by at least two fixing bolts, which facilitates disassembly and maintenance.
[0027] As a preferred option, a hydraulically controlled cylinder is further provided on the testing platform 3 between a pair of sliding guide rails 5. The hydraulically controlled cylinder can push or perform other actions on the other end of the workpiece.
[0028] As a preferred option, the insertion slot 11 is a rectangular groove, and a pair of telescopic guide blocks 14 are provided on both sides of the fixing plate 12. These guide blocks 14 are inserted into the insertion slot 11 and match the width of the insertion slot 11. The guide blocks 14 cooperate with the insertion slot 11 to guide the installation of the fixing plate 12.
[0029] As a preferred embodiment, the pair of guide blocks 14 are further connected to both sides of the fixing plate 12 by at least two pairs of telescopic rods, and the tail end of the pair of guide blocks 14 is provided with a pair of columnar limiting blocks. The pair of guide blocks 14 and the fixing plate 12 are connected by a telescopic structure to match workpieces with different widths.
[0030] As a preferred option, the fixing plate 12 is further provided with a fixing threaded hole, and the clamping fixing bolt 13 is assembled in the fixing threaded hole to facilitate the adjustment of the position of the clamping fixing bolt 13.
[0031] In summary, this steel structure strength testing device for building engineering, based on the current steel component strength testing machine, uses a clamping method to limit the two ends of the workpiece. Furthermore, by using a fixed plate 12 installed on the empty sides of the workpiece in an insert manner, and using the clamping fixing bolts 13 on the fixed plate 12 to limit the empty sides of the workpiece, the problem of workpiece head displacement when the workpiece is subjected to two pairs of relative forces is avoided, thus avoiding the problem of inaccurate test results.
