Description

Technical Field

[0001] The utility model relates to the technical field of raft slab phased construction, in particular to a shear key structure which is convenient for splicing. Background Art

[0002] At present, with the development of modern cities, the building volume and the scale of foundation pit rafts are getting larger and larger. In the process of phased development, it is inevitable that the raft of the second phase (later development) is connected to the raft of the first phase (earlier development).

[0003] During construction, the first and second phases of the project will be connected to solve the problem of uneven settlement that may occur between the two phases. The shear keys are embedded in the raft slab of the building. Half of the shear keys are embedded in the first phase raft slab and the other half are embedded in the second phase raft slab at the separation point between the first phase raft slab and the second phase raft slab. They are used to bear uniform loads on both sides and bear the shear forces on both sides. However, in the process of using the existing technology, two adjacent waterstop steel plates are usually connected together by bolts or welding. Since the waterstop steel plates are only subjected to vertical loads and the sides are limited by the load of H-shaped steel, both methods currently have low construction efficiency. For this reason, we propose a shear key structure that is easy to splice. Utility Model Content

A pressing plate is fixed on one side of the transmission round rod, and a second-stage transmission plate is fixed on the other side of the transmission round rod. An inclined surface is provided on the top of the pressing plate, and the inclined surface fits tightly with the bottom of the locking plate.

[0010] Preferably, the helical tooth-shaped ridges are all inclined in a direction away from the H-shaped steel.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example 1

[0026] Reference Figure 1-4 A shear key structure that is easy to splice includes an H-shaped steel 1 and waterstop steel plates 4 fixed on both sides of the H-shaped steel 1. The top and bottom of the H-shaped steel 1 are provided with connecting surfaces 2, and a plurality of bolts 3 are evenly fixed on the connecting surfaces 2. The inner sides of the two waterstop steel plates 4 are equipped with a splicing mechanism, which is used for quick connection between two adjacent H-shaped steels 1.

[0027] The splicing mechanism includes a docking ridge plate 5, a ridge slot 6 and a docking piece. A docking ridge plate 5 is fixed at one end of the waterstop steel plate 4 on the left, and a ridge slot 6 corresponding to the position of the docking ridge plate 5 is opened on the top of the inner side of the waterstop steel plate 4 on the right. The ridge slot 6 is slidingly connected to the docking ridge plate 5. A docking piece is installed between the two waterstop steel plates 4. The docking ridge plate 5 and the ridge slot 6 are matched with a dovetail groove. When the docking ridge plate 5 and the ridge slot 6 are connected, the docking ridge plate 5 and the ridge slot 6 cannot be separated from each other vertically.

[0028] The docking parts include a locking plate 7, a transmission round rod 8, a pressing plate 9, a second-stage transmission plate 10 and an inclined surface 11. Locking plates 7 are fixed on both sides of the docking ridge plate 5. One side of the H-shaped steel 1 is located inside the right waterstop steel plate 4 and is rotatably connected to two transmission round rods 8. A pressing plate 9 is fixed on one side of the transmission round rod 8, and a second-stage transmission plate 10 is fixed on the other side of the transmission round rod 8. An inclined surface 11 is provided on the top of the pressing plate 9, and the inclined surface 11 fits tightly with the bottom of the locking plate 7. There is a gap between the top of the second-stage transmission plate 10 and the waterstop steel plate 4.

[0029] A plurality of beveled tooth-shaped ridges 12 are evenly fixed on the top of the inclined surface 11, and a plurality of matching recesses 13 corresponding to the positions of the beveled tooth-shaped ridges 12 are evenly distributed on the bottom of the locking plate 7. The matching recesses 13 transitionally match the beveled tooth-shaped ridges 12. Through the setting of the beveled tooth-shaped ridges 12, when the locking plate 7 is placed on the inclined surface 11 under force, the beveled tooth-shaped ridges 12 can be quickly connected with the matching recesses 13.

[0030] The oblique tooth-shaped protrusions 12 are all inclined in a direction away from the H-shaped steel 1, so that the matching recesses 13 can be tightly engaged with the oblique tooth-shaped protrusions 12 after being connected and are not easy to fall off.

[0031] Example 2

[0032] Further optimize Example 1, specifically, Figure 5 As shown, the bottom of the second-stage transmission plate 10 is equipped with a reverse tensioning mechanism.

[0033] The reverse tensioning mechanism includes a mounting side plate 14, an inner cross plate 15, a cylindrical groove 16 and a deformed protrusion 17. The bottom of the second-stage transmission plate 10 is fixed with a mounting side plate 14, and the bottom of the mounting side plate 14 is fixed with a cylindrical protrusion in an integrated manner. The two ends of the inner side of the water-stop steel plate 4 on the left are fixed with an inner cross plate 15. The top of the inner cross plate 15 is provided with a cylindrical groove 16 corresponding to the position of the cylindrical protrusion. The cylindrical protrusion is slidably connected to the cylindrical groove 16, and a deformed protrusion 17 is fixed between the two inner cross plates 15. When docked, the cylindrical protrusion is inserted into the cylindrical groove 16. Due to the shape limitation of the cylindrical protrusion, the cylindrical protrusion cannot be vertically disengaged from the cylindrical groove 16. When the second-stage transmission plate 10 is subjected to force to pull the mounting side plate 14, the cylindrical protrusion can cooperate with the cylindrical groove 16 to increase the vertical tensioning effect of the inner cross plate 15.

[0034] From the above, we can know that:

[0035] The present invention addresses the following technical issues: However, in the existing technology, two adjacent waterstop steel plates are usually connected together by bolts or welding. Since the waterstop steel plates are only subjected to vertical loads and the sides are limited by the load of H-shaped steel, both methods have low construction efficiency. The technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is as follows:

[0036] During use, when it is necessary to connect two adjacent H-shaped steels 1 into a whole, the docking ridge plate 5 of one of the H-shaped steels 1 is inserted into the ridge slot 6 on the other H-shaped steel 1, and the cylindrical protrusion at the bottom of the side plate 14 is also inserted into the cylindrical groove 16, so that the bottom of the locking plate 7 contacts the inclined surface 11. Under the guidance of the inclined surface 11, the beveled tooth protrusion 12 gradually engages with the matching recess 13 one by one, so that the bottom of the locking plate 7 is tightly fitted with the inclined surface 11. At the same time, the inclined surface 11 is forced to drive the transmission rod 8 to rotate, and the transmission rod 8 drives the second-stage transmission plate 10 to rotate, so that the second-stage transmission plate 10 pulls the cylindrical protrusion through the side plate 14, so that the internal cross plate 15 is forced to be tightened upward, so that the deformed protrusion 17 produces a certain deformation, thereby increasing the firmness of the connection between the two adjacent waterstop steel plates 4.

[0037] Through the above configuration, this application can certainly solve the above technical problems and achieve the following technical effects:

[0038] The utility model realizes the fast and efficient splicing function between two adjacent H-shaped steel parts 1 and the waterstop steel plate 4 parts through the structural design of the splicing mechanism and the reverse tensioning mechanism, greatly improving the ease of use and operating efficiency of the device and improving the efficiency of construction.
