[0002] Simple houses are usually built with steel frame structures, which form the frame structure of the house such as columns and beams through the steel structure, and then the wall panels are installed on the frame structure. Therefore, in the process of erecting simple houses, square steel is generally used as the columns of the house. At this time, since a single square steel cannot meet the construction height of the house, the square steel needs to be connected.

[0003] For example, the prefabricated residential seismic split-level connector with publication number CN205917879U still has the following shortcomings in actual use:

[0004] The above patent can only be installed by inserting and fixing specific square steels because the size is fixed. However, since it is assembled, there will still be gaps that cause shaking, which reduces the stability of the device.

[0005] At the same time, the above device itself does not have a device for consuming energy and therefore has a poor earthquake resistance effect. Utility Model Content

[0006] In order to solve the problems raised in the above-mentioned background technology, the utility model provides an anti-seismic staggered-level connector for an assembled house, which has the advantages of fixing square steel more stably and increasing the anti-seismic effect.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 4 As shown, the utility model provides an assembled residential earthquake-resistant staggered-level connector, including a flange 1 and a connecting end 3 fixed in the middle of the flange 1, a cone 2 is fixed at the lower end of the connecting end 3, and a transition section 11 is provided between the cone 2 and the flange 1. The above-mentioned installation method is the same as the existing installation method, and the function of the structure is also the same as the existing structure, so it will not be repeated.

[0026] A plurality of rectangular limit grooves 7 and a rectangular damping groove 8 are provided around the lower end of the flange 1. The plurality of limit grooves 7 and the damping grooves 8 are arranged alternately and the length of the limit groove 7 is much smaller than the length of the damping groove 8. The damping groove 8 is filled with sand and gravel 15. It should be noted that the sand and gravel 15 cannot be filled completely (e.g. Figure 2 As shown in the figure, it is necessary to reserve space for the sand and gravel 15 to bounce so as to achieve the effect of shock absorption. A cover plate 9 is fixed to the lower end of the flange 1 by a number of screws. The outer size of the cover plate 9 is the same as the outer size of the flange 1. The relative position of the surface of the cover plate 9 and the limiting groove 7 is fixed with a limiting block 10. The limiting block 10 is inserted into the limiting groove 7, and the gap between the limiting block 10 and the limiting groove 7 is matched to achieve the supporting and fixing effect. The end of the limiting block 10 abuts against the top of the inner cavity of the limiting groove 7 to reduce the gap and prevent the device from shaking.

[0027] The tensioning mechanism 5 includes a movable seat 53 fixed to the upper opening inside the connecting end 3 through a transverse plate 16, one end of the four transverse plates 16 is fixed to the four sides of the movable seat 53 respectively, and the other end of the four transverse plates 16 is fixed to the four sides of the connecting end 3 respectively. Notches are provided in the four directions of the upper end of the movable seat 53, and connecting rods 52 are arranged in the four notches through the rotation of a rotating shaft. One end of the four connecting rods 52 is fixed with a bottom plate 51 that abuts against the inner wall of the square steel, and the bottom plate 51 is arranged with an inclined surface toward the inner wall of the square steel, so that as the bottom plate 51 rotates, a section of the inclined surface can always fit with the inner wall of the square steel to achieve a tightening effect. The tensioning mechanism 5 also includes a movable seat 54 (such as a movable seat 54) arranged at one end of the connecting rod 52 away from the bottom plate 51 through the rotation of the rotating shaft Figure 1As shown in the figure, the moving seat 54 is located inside the movable seat 53 and moves longitudinally, the lower end of the moving seat 54 protrudes from the lower end of the movable seat 53, thereby leaving a distance for the moving seat 54 to move, and one side of the lower end of the moving seat 54 is arranged in an arc shape, and the moving column 14 is located on one side of the fastening bolt 4 and is fixed with an inclined block 13 abutting against one side of the lower end of the moving seat 54, and the inclined block 13 is arranged with an inclined surface toward the arc-shaped side of the lower end of the moving seat 54, thereby achieving the effect of squeezing and pushing.

[0028] A transverse groove 12 for sliding of the movable column 14 is provided in the middle of the opposite side of the connecting end 3. The transverse groove 12 is set to be rectangular, and the transverse groove 12 away from the fastening bolt 4 is set to be a through groove. An internal threaded hole 6 connected to the transverse groove 12 is provided on one side of the connecting end 3. The internal thread of the internal threaded hole 6 is connected to the fastening bolt 4, and the rod end of the fastening bolt 4 abuts against the movable column 14. Under normal circumstances, a distance is left between the end of the movable column 14 away from the fastening bolt 4 and the outer end face of the transverse groove 12 for the movable column 14 to move. It should be noted that when the movable seat 54 moves upward to the top, one end of the movable column 14 does not protrude from the end face of the transverse groove 12.

[0029] Principle and process of this utility model:

[0030] The cone 2 and the transition section 11 of the device are installed on the square steel at the lower end according to the existing installation method. Then, the user inserts another square steel into the groove formed between the flange 1 and the connecting end 3. At the same time, the tensioning mechanism 5 is inserted into the square steel at the upper end, and the internal threaded hole 6 is made to correspond to the screw hole on the surface of the square steel at the upper end.

[0031] Subsequently, the user uses a socket tool to pass the fastening bolt 4 through the screw hole of the square steel and then screws it into the internal threaded hole 6. As the fastening bolt 4 continues to rotate, its rod portion contacts one end of the moving column 14 and the moving column 14 slides in the transverse groove 12. The moving column 14 drives the inclined block 13 to move, and the inclined block 13 drives the moving seat 54 to move upward. At the same time, the moving seat 54 drives the connecting rod 52 to rotate around the rotating shaft, thereby driving the connecting rod 52 to drive the bottom plate 51 to move in the opposite direction of the moving seat 54, and then drives the bottom plate 51 to rotate downward, thereby making the bottom plate 51 press against the inner wall of the square steel at the upper end to achieve a fixing effect. The setting of the four bottom plates 51 can fix the square steel on all sides of the upper end. At the same time, in order to make the four bottom plates 51 move the same distance to increase synchronization, and the lengths of the four connecting rods 52 are different, they need to be set according to the size of the connecting end 3.

[0032] After installation, when the square steel is vibrated, the gravel 15 inside the damping groove 8 will bounce up due to the vibration, thereby absorbing the energy, reducing the vibration energy and improving the anti-seismic effect.

[0033] In summary, the device has the advantages of fixing the square steel more stably and increasing the earthquake resistance effect.
