[0001] This utility model relates to the field of building technology, and in particular to a prefabricated component connector with enhanced seismic performance. Background Technology

[0002] The concept of prefabricated components refers to the prefabrication of structural components that will be used in advance, mainly assembly components that are prefabricated in the factory according to design specifications.

[0003] A search revealed Chinese patent CN217896913U, which discloses a precast floor slab connector for precast assembled steel structure buildings. The connector includes a steel beam with precast floor slabs on the upper sides of both ends. An installation mechanism is located on the upper side of the steel beam between the two precast floor slabs. A reinforcement mechanism is located on the upper side of the precast floor slabs. The installation mechanism consists of a fixing plate, a rectangular groove, mounting blocks, a mounting plate, and a screw. The fixing plate is fixedly connected to the side of the precast floor slab near the middle of the steel beam. The rectangular groove is located on the upper side of the fixing plate. The mounting blocks are located inside the rectangular groove. The mounting plate is fixedly connected between the two mounting blocks. The screw is located between the mounting plate and the steel beam.

[0004] When precast floor slabs are installed, concrete mortar is usually used to fill and compact the gap between two adjacent precast floor slabs. However, after a certain period of use, the concrete used for compaction may crack under a certain bearing pressure, thereby reducing the overall seismic strength of the floor slab. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, concrete used for dense filling may cause cracks in the concrete mortar between two adjacent precast floor slabs under a certain bearing pressure, thereby reducing the overall seismic strength of the floor slab. Therefore, this invention proposes a seismically enhanced precast component connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A seismically enhanced precast component connector includes a connecting steel and a connecting groove disposed at both ends of the connecting steel. A connecting plate is engaged within the connecting groove, and a protrusion extends from the end of the connecting plate, with the outer wall of the protrusion abutting against the inner wall of the connecting groove. A reinforcing bar is fixedly connected to the protrusion, wherein both ends of the reinforcing bar extend into the connecting groove, the connecting groove is filled with a filling grout, and the filling grout covers the outside of the reinforcing bar.

[0008] To facilitate the fixed connection of the connecting steel and the connecting plate, preferably, the connecting steel has a first through hole and the connecting plate has a second through hole, and the two sets of through holes are fixedly connected by through ribs.

[0009] To improve the stable connection between the connecting steel and the connecting plate, the connecting plate is further provided with a first insertion hole, which is connected to a second through hole. The through rib is provided with a second insertion hole, and the two sets of insertion holes are fixedly connected by a limiting rib.

[0010] To facilitate the positioning of the limiting rib, preferably, the two ends of the limiting rib are fixedly connected to limiting plates.

[0011] To improve the seismic performance between the connecting steel and the connecting plate, preferably, the connecting steel has a first through hole and the connecting plate has a second through hole. The two sets of through holes are fixedly connected by connecting ribs, and the through holes are located between the two sets of through holes.

[0012] To facilitate the filling of the grout, preferably, the cross-sectional area of ​​the protrusion is smaller than the cross-sectional area of ​​the connecting groove.

[0013] Compared with the prior art, this utility model provides a seismically enhanced prefabricated component connector, which has the following beneficial effects:

[0014] 1. This seismic-enhanced precast component connector has a reinforcing bar installed on the protrusion, with both ends of the reinforcing bar extending into the connecting groove. The filling grout covers the outside of the reinforcing bar. When the filling grout solidifies, it can work in conjunction with the outer wall of the reinforcing bar to reinforce the filling cavity and improve the seismic performance between the connecting plate and the connecting steel.

[0015] 2. This seismic-enhanced precast component connector, after the concrete grout or epoxy resin grout filling the cavity has cured after the connector plate has been in use for a certain period of time, cooperates with the connecting bars, through bars and dowel bars to withstand a certain pressure, thereby improving the seismic effect between the connector plate and the connecting steel, reducing the phenomenon of cracking in the concrete grout or epoxy resin grout, and improving the overall seismic strength of the connector plate.

[0016] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model can make the concrete grout or epoxy resin grout in the filling cavity, after curing, cooperate with the connecting bars, through bars and insert bars to withstand a certain pressure, thereby improving the seismic effect between the connecting plate and the connecting steel, reducing the phenomenon of cracks in the concrete grout or epoxy resin grout, and improving the overall seismic strength of the connecting plate.

[0027] Example:

[0028] Reference Figures 1-7 A seismically enhanced precast component connector includes a connecting steel 1 and a connecting groove 4 disposed at both ends of the connecting steel 1. A connecting plate 5 is engaged within the connecting groove 4, and a protrusion 6 extends from the end of the connecting plate 5, with the outer wall of the protrusion 6 abutting against the inner wall of the connecting groove 4. A reinforcing bar 10 is fixedly connected to the protrusion 6, with both ends of the reinforcing bar 10 extending into the connecting groove 4. The connecting groove 4 is filled with a filling grout, and the filling grout covers the outside of the reinforcing bar 10.

[0029] In this application, the connecting steel 1 is an I-beam, whose cross-sectional shape gives it strong load-bearing capacity and flexibility. Connecting grooves 4 are formed at both ends of the connecting steel 1; these grooves are the two side grooves of the I-beam, used to connect the connecting plate 5. In this application, the connecting plate 5 is a precast floor slab. Please refer to [reference needed]. Figure 5 and Figure 6 As shown in the figure, the diagram is only a partial schematic diagram of the precast floor slab, and the length, width, height and volume of the precast floor slab need to be precast according to the actual construction dimensions.

[0030] The connecting plate 5 extends into the connecting groove 4 of the connecting steel 1 through its end. The cross-sectional area of ​​the protrusion 6 is smaller than that of the connecting groove 4. The cross-section of the protrusion 6 is trapezoidal, while the cross-section of the connecting groove 4 is rectangular. When the protrusion 6 extends into the connecting groove 4, a filling cavity is formed between the connecting groove 4 and the protrusion 6. The filling cavity can be filled with a filling grout, which can be concrete grout or epoxy resin grout.

[0031] In addition, a reinforcing bar 10 is installed on the protrusion 6, and both ends of the reinforcing bar 10 extend into the connecting groove 4 respectively. The filling grout covers the outside of the reinforcing bar 10. When the filling grout solidifies, it can cooperate with the outer wall of the reinforcing bar 10 to reinforce the filling cavity and improve the seismic resistance between the connecting plate 5 and the connecting steel 1.

[0032] In order to improve the connection effect between the connecting plate 5 and the connecting steel 1, a first through hole 2 is provided on the connecting steel 1, and a second through hole 7 is provided on the connecting plate 5. The two sets of through holes are fixedly connected by through ribs 11.

[0033] By passing the through rib 11 through the first through hole 2 and the second through hole 7, the position of the connecting plate 5 can be fixed in advance.

[0034] A first insertion hole 9 is provided on the connecting plate 5, and the first insertion hole 9 is connected to the second through hole 7. A second insertion hole 12 is provided on the through rib 11, and the two sets of insertion holes are fixedly connected by the limiting rib 14. The two ends of the limiting rib 14 are respectively fixedly connected to the limiting plate 15.

[0035] The position of the through rib 11 can be limited and fixed by the limiting rib 14 to prevent the through rib 11 from shaking inside.

[0036] A first through hole 3 is provided on the connecting steel 1, and a second through hole 8 is provided on the connecting plate 5. The two sets of through holes are fixedly connected by the connecting rib 13, and the through holes are located between the two sets of through holes.

[0037] The connecting rib 13 can limit the position of the connecting plate 5 and the connecting steel 1 to prevent lateral misalignment.

[0038] After the connecting plate 5 has been used for a certain period of time, the concrete grout or epoxy resin grout filling the cavity will solidify and cooperate with the connecting bar 13, the through bar 11 and the dowel bar 10 to withstand a certain pressure. This will improve the seismic performance between the connecting plate 5 and the connecting steel 1, reduce the occurrence of cracks in the concrete grout or epoxy resin grout, and improve the overall seismic strength of the connecting plate 5.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
