Description

Technical Field

[0001] The present application relates to the technical field of detection structures, and more specifically, to a stress detection structure for a building steel structure. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Building steel structure is mainly made of construction steel, and building steel structure needs to undergo prestressing testing before normal use.

[0003] The document with the prior art announcement number CN220170743U provides a stress detection device for building steel structures. By setting a placement groove on the support, and the placement groove is a V-shaped structure, when the steel bars are placed inside the placement groove, since the bottom size of the placement groove is gradually reduced, steel bars of different sizes can be supported and fixed, and there is no need to use a complex transmission structure to fix the steel bars; by setting a baffle, screw and nut on the top of the placement groove, after the steel bars are placed inside the placement groove, the placement groove opening is blocked by the baffle, and then it is fixed by the cooperation of the screw and nut, so that it can play a certain shielding function for the steel bars, and this is not an absolute compression and fixing effect on the steel bars.

[0004] Although this device has many beneficial effects, it still has the following problems: since the cross-section of the placement groove is V-shaped, after the steel bars are squeezed, some of the steel bars will be stuck in the placement groove and difficult to remove. It takes a long time for the staff to remove the stuck steel bars, which can easily reduce the staff's detection efficiency. In view of this, we propose a stress detection structure for building steel structures. Utility Model Content

DETAILED DESCRIPTION

[0028] The present application is further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a stress detection structure for a building steel structure. The stress detection structure for a building steel structure comprises: a detection platform 1;

[0030] Support plates 2 are fixedly connected to both sides of the top of the testing platform 1. A through groove for placing steel bars is opened on one side of the support plate 2. A fixing frame 11 is fixedly connected to one side of the top of the testing platform 1. A hydraulic cylinder 4 is installed on the inside of the fixing frame 11. A horizontal plate 7 is fixedly sleeved on the outside of the output shaft of the hydraulic cylinder 4. A pressure sensor 5 is installed at the bottom of the horizontal plate 7. An extrusion head 6 is fixedly connected to the bottom of the pressure sensor 5.

[0031] A lifting mechanism 3 is provided on the outside of the horizontal plate 7 to prevent the steel bars from getting stuck in the through groove;

[0032] The lifting mechanism 3 includes a connecting plate 31, which is slidably mounted on the outside of the transverse plate 7. A lifting hook 37 is provided on one side of the connecting plate 31 to facilitate pulling out the stuck steel bars.

[0033] Reference Figure 1 and Figure 4 The cross section of the through slot is V-shaped, which makes it easy to place steel bars of different thicknesses in the through slot.

[0034] Reference Figure 2 and Figure 3 A groove is provided on one side of the connecting plate 31, and a through hole is provided through the bottom of the connecting plate 31. A screw rod 38 is rotatably connected in the through hole. A screw sleeve 39 is provided on the outer thread of the screw rod 38. The screw sleeve 39 is fixedly connected to the lifting hook 37, and the screw sleeve 39 is slidably connected in the groove, so that the distance between the lifting hook 37 and the horizontal plate 7 can be adjusted according to the thickness of the steel bar.

[0035] Reference Figure 1 and Figure 2 A damping bearing is installed in the through hole, and the screw rod 38 is located in the damping bearing, so that there is a large resistance to the rotation of the screw rod 38, preventing the screw rod 38 from rotating at will, and playing the role of locking the screw rod 38.

[0036] Reference Figure 2 and Figure 3 There are sliding grooves on both sides of the horizontal plate 7, and sliders 32 are fixedly connected to both sides of the inner wall of the connecting plate 31. The sliders 32 are slidably connected to the sliding grooves, so that the connecting plate 31 can move along the direction of the sliding grooves.

[0037] Reference Figure 2 and Figure 3The top of the connecting plate 31 is fixedly connected to a fixing plate 33 on both sides, and a plurality of sockets are opened on both sides of the top of the horizontal plate 7. The top of the fixing plate 33 is slidably connected with an insertion rod 34, and the bottom end of the insertion rod 34 is located in the socket, so as to facilitate the positioning of the connecting plate 31.

[0038] Reference Figure 2 and Figure 3 The top of the insertion rod 34 is fixedly connected to a pull plate 35, the bottom of the pull plate 35 is fixedly connected to a spring 36, and the bottom end of the spring 36 is fixedly connected to the top of the fixed plate 33 to prevent the insertion rod 34 from rising and moving at will.

[0039] Reference Figure 1 and Figure 4 , screws 9 are fixedly connected on both sides of the top of the supporting plate 2, a baffle 8 is provided on the sliding sleeve outside the screw 9, and a nut 10 is provided on the threaded sleeve outside the screw 9, which can shield the two ends of the steel bar and avoid the phenomenon of excessive warping at both ends of the steel bar.

[0040] Reference Figure 1 and Figure 2 The size of the inner side of the connecting plate 31 is larger than the size of the pressure sensor 5 and the extrusion head 6, so that the movement of the connecting plate 31 will not be blocked by the pressure sensor 5 and the extrusion head 6.

[0041] Reference Figure 1 A slot is provided through the top of the inspection platform 1 so that the lifting mechanism 3 can normally descend and move into the slot, and the lifting mechanism 3 will not be blocked by the inspection platform 1 when it descends.

[0042] The implementation principle of the stress detection structure of a building steel structure in the embodiment of the present application is as follows: when the staff needs to detect the steel bars, the steel bars are placed in the through groove, and then the hydraulic cylinder 4 is started to drive the cross plate 7, the pressure sensor 5 and the extrusion head 6 to move downward to squeeze the steel bars, thereby performing stress detection on the steel bars. When the detection is completed, the staff can take the steel bars out of the through groove. Since the cross section of the through groove is V-shaped, when the steel bars are pressed down, some steel bars will be stuck in the through groove. At this time, the staff can pull the pull plate 35 to drive the insertion rod 34 to move upward, so that the insertion rod 34 moves out of one of the insertion holes, and then the staff pushes the connecting plate 31 and the lifting hook 37 to move along the direction of the slide groove, so that the lifting hook 37 moves to the bottom of the steel bar, and then releases the pull plate 35 to allow the insertion rod 34 to move downward and insert into another socket to position the fixed plate 33 and the connecting plate 31. Then, the staff drives the cross plate 7 to move upward through the hydraulic cylinder 4. The upward movement of the cross plate 7 can drive the connecting plate 31 to move upward through the slider 32 and the fixed plate 33. The upward movement of the connecting plate 31 can drive the lifting hook 37 to move upward through the screw rod 38 and the screw sleeve 39, so that the stuck steel bar is lifted by the lifting hook 37. When the steel bar is lifted, the staff can remove the steel bar from the through groove, and then move the connecting plate 31 and the lifting hook 37 to the initial position according to the above method, so that the next steel bar can be detected by the extrusion head 6.

[0043] The embodiment of the present application provides a stress detection structure for a building steel structure. By setting a pulling mechanism 3, when the steel bar is squeezed and the steel bar happens to be stuck in the through groove, the staff can quickly pull up the stuck steel bar, thereby facilitating the staff to quickly remove the steel bar and improving the staff's detection efficiency.
