Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to an assembled steel structure floor slab for construction engineering. Background Art

[0002] With the continuous development of the construction industry, prefabricated buildings have attracted widespread attention due to their advantages such as fast construction speed, controllable quality, environmental protection and energy saving. Among them, steel structure has become one of the main structural forms of prefabricated buildings due to its high strength, light weight and convenient construction. In particular, prefabricated steel structure floor, as an important part of the building, its performance directly affects the safety and comfort of the entire building.

[0003] However, traditional steel structure floors are mostly installed by on-site welding or bolt connection, both of which have obvious shortcomings. First, on-site welding is not only time-consuming and labor-intensive, but the welding quality is greatly affected by environmental factors, making it difficult to ensure the stability and durability of the connection. Secondly, although bolt connection is relatively simple, it requires precise hole alignment during actual operation. When the number of bolts is large, the installation efficiency is low. At the same time, bolts are prone to rust when exposed to the air for a long time, affecting the safety of the structure.

[0004] Therefore, a prefabricated steel structure floor for construction engineering is needed to solve the above problems. Summary of the invention

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0030] like Figure 2 and Figure 4 As shown, the embodiment of the present invention discloses an assembled steel structure floor for construction engineering, including a floor 1, a connecting card plate 2 is fixedly installed on both sides of the floor 1, and a connecting card slot 3 matching the connecting card plate 2 is opened on the other two sides of the floor 1, a driving mechanism is arranged on the upper surface of the floor 1, and a reinforcing plug rod 4 is slidably arranged on both sides of the floor 1, and the reinforcing plug rod 4 is drivingly connected to the driving mechanism, and a reinforcing plug hole 5 matching the reinforcing plug rod 4 is opened on the other two sides of the floor 1, and locks matching each other are arranged on the reinforcing plug rod 4 and in the reinforcing plug hole 5.

Through double locking, not only the safety during work is guaranteed, but also the connection operation is convenient, which greatly improves the work efficiency.

[0031] like Figure 1-2 As shown, the floor 1 is square, the connecting card plate 2 is fixedly installed on the two adjacent sides of the floor 1, the connecting card plate 2 is in the shape of 7, and a filling plate 6 is fixedly installed on the top of the outer side of the floor 1, and the filling plate 6 is located directly above the connecting card plate 2. The connecting card slot 3 is opened on the other two adjacent sides of the floor 1, and the connecting card slot 3 is in the shape of 7. The top and the outer side of the connecting card slot 3 are both transparent ends; after the connecting card plate 2 is inserted into the connecting card slot 3, the filling plate 6 will block the top of the connecting card slot 3.

[0032] like Figure 2-3As shown, a first retracted cavity 7 is provided on the inner side of the connecting slot 3, and a blocking slide plate 9 is slidably installed inside the first retracted cavity 7 through a first push-up spring 8. A second retracted cavity 10 is provided on both sides of the connecting slot 3, and a blocking inclined plate 12 is slidably installed inside the second retracted cavity 10 through a second push-up spring 11. When the blocking slide plate 9 is completely retracted into the first retracted cavity 7 and the inclined end of the blocking inclined plate 12 extends out of the second retracted cavity 10, the blocking slide plate 9 pushes against the blocking inclined plate 12. By setting the blocking The slide plate 9 and the blocking inclined plate 12, when the connecting card plate 2 is inserted into the connecting card slot 3, the connecting card plate 2 will first push the blocking inclined plate 12 into the second retracted cavity 10, at this time, the blocking slide plate 9 is against the connecting card plate 2 and will not slide out, when the connecting card plate 2 is fully inserted into the connecting card slot 3, the blocking slide plate 9 extends out between the connecting card plate 2 and the filling plate 6, locks the connecting card plate 2 to prevent the connecting card plate 2 from sliding out, and has the effect of automatically performing preliminary connection locking, and at this time the upper surface of the filling plate 6 is flush with the upper surface of the floor slab 1.

[0033] like Figure 4 and Figure 8 As shown, the driving mechanism includes two driving chambers 13, and the two driving chambers 13 are both opened near the middle of the upper surface of the floor 1. A pressing plate 15 is slidably installed at the bottom of the driving chamber 13 through a third push-up spring 14. When the third push-up spring 14 is not pressed, the upper surface of the pressing plate 15 is flush with the upper surface of the floor 1. A matching groove 16 is vertically opened on one side of the pressing plate 15 close to the reinforcing rod 4, and a driving tooth plate 17 is fixedly installed on one side of the matching groove 16.

[0034] like Figure 5 As shown, installation sliding holes 18 are opened near the middle of the two adjacent sides of the floor 1, and the reinforcement plug rod 4 slides in the installation sliding hole 18. The inner end of the reinforcement plug rod 4 is coaxially opened with a screw hole 19, and the inner end of the installation sliding hole 18 is rotatably installed with an installation shaft 20. One end of the installation shaft 20 is coaxially fixedly installed with a driving screw rod 21, and the driving screw rod 21 is threadedly installed in the screw hole 19.

[0035] like Figure 5 As shown, one end of the mounting shaft 20 away from the driving screw 21 extends into the driving cavity 13 and a gear ring 22 is coaxially rotatably mounted on the outer surface. The gear ring 22 rotates in the matching groove 16 and is meshedly connected with the driving gear plate 17 .

[0036] like Figure 7As shown, the outer surface of the mounting shaft 20 is provided with a fourth retracted cavity 23, and a beveled tooth block 25 is slidably installed inside the fourth retracted cavity 23 through a fifth abutting spring 24. The inner side of the gear ring 22 is provided with a beveled tooth groove 26 matching the beveled tooth block 25, and the beveled tooth block 25 abuts against the beveled tooth groove 26; the driving screw 21 is installed with the inner thread of the reinforcing plug rod 4, and one end of the driving screw 21 is connected to the driving tooth plate 17 on the pressing plate 15 through the mounting shaft 20 and the gear ring 22. A bevel gear block 25 and a bevel gear groove 26 are provided between the mounting shaft 20 and the gear ring 22. When the pressing plate 15 is pressed down, the driving gear plate 17 drives the gear ring 22 to drive the driving screw 21 to rotate, and drives the reinforcement plug rod 4 to slide outward. When the pressing plate 15 rebounds and slides up, due to the action of the bevel gear block 25 and the bevel gear groove 26, the gear ring 22 will not drive the driving screw 21 to rotate. By reciprocatingly pressing the pressing plate 15, the reinforcement plug rod 4 can be inserted into the reinforcement socket 5, which is easy to operate.

[0037] like Figure 5-6 As shown, the locking mechanism includes a third retracted cavity 27 and a locking groove 28. The third retracted cavity 27 is opened on the side of the reinforcement socket 5. A locking inclined plate 30 is slidably installed inside the third retracted cavity 27 through a fourth abutting spring 29. The locking groove 28 is opened on the side of the reinforcement plug rod 4 to match the locking inclined plate 30. By slidingly setting the locking inclined plate 30 on the side of the reinforcement socket 5, and opening a locking groove 28 matching the locking inclined plate 30 on the side of the reinforcement plug rod 4, when the outer end of the reinforcement plug rod 4 abuts against the inner end of the reinforcement socket 5, the locking inclined plate 30 is stuck in the locking groove 28, locking the reinforcement plug rod 4 to prevent the reinforcement plug rod 4 from sliding out, thereby automatically fixing the connection of the floor slab 1 again, facilitating operation, and improving work efficiency.

[0038] Working principle:

[0039] When multiple floor slabs 1 need to be assembled and installed, the connecting card plate 2 on one floor slab 1 is inserted into the connecting card slot 3 on another floor slab 1. The connecting card plate 2 will press the blocking inclined plate 12 into the second retracted cavity 10. When the connecting card plate 2 is fully inserted into the connecting card slot 3, the blocking slide plate 9 will slide out between the connecting card plate 2 and the filling plate 6, and then the pressing plate 15 is pressed down reciprocatingly, so that the driving tooth plate 17 drives the tooth ring 22 to drive the driving screw 21 to rotate, drive the reinforcement plug rod 4 to slide out, and insert it into the reinforcement plug hole 5 until the locking inclined plate 30 is inserted into the locking groove 28, wherein the cross-section of the reinforcement plug rod 4 is square, and when the driving screw 21 rotates, the reinforcement plug rod 4 will not rotate under the restriction of the installation slide hole 18 By setting mutually matching connecting card plates 2 and connecting card slots 3, as well as mutually matching reinforcing plug rods 4 and reinforcing sockets 5, when multiple floor slabs 1 need to be assembled and installed, the connecting card plates 2 can be first inserted into the connecting card slots 3 to make a preliminary connection between the floor slabs 1, and then the reinforcing plug rods 4 can be driven by the operating driving mechanism to be inserted into the reinforcing sockets 5 until the locking mechanisms on the reinforcing plug rods 4 and the reinforcing sockets 5 are locked. Through double locking, not only the safety during work is ensured, but also the connection operation is convenient, which greatly improves the work efficiency. By setting the blocking slide plate 9 and the blocking inclined plate 12, when the connecting card plate 2 is inserted into the connecting card slot 3, the connecting card plate 2 will first push the blocking inclined plate 12 into the second shrinkage cavity 10 When the connecting card plate 2 is fully inserted into the connecting card slot 3, the blocking slide plate 9 extends out between the connecting card plate 2 and the filling plate to lock the connecting card plate 2 and prevent the connecting card plate 2 from sliding out, thereby automatically performing the initial connection locking effect. The driving screw 21 is installed with the inner thread of the reinforcing plug rod 4, and one end of the driving screw 21 is connected to the driving tooth plate 17 on the pressing plate 15 through the mounting shaft 20 and the gear ring 22, and an oblique tooth block 25 and an oblique tooth groove 26 are arranged between the mounting shaft 20 and the gear ring 22. When the pressing plate 15 is pressed down, the driving tooth plate 17 drives the gear ring 22 to drive the driving screw 21 to rotate, driving the reinforcing plug rod 4 slides outward, and when the pressing plate 15 rebounds and slides upward, due to the action of the oblique tooth block 25 and the oblique tooth groove 26, the gear ring 22 will not drive the driving screw 21 to rotate. By reciprocatingly pressing the pressing plate 15, the reinforcement plug rod 4 can be inserted into the reinforcement plug hole 5, which is convenient for operation. A locking inclined plate 30 is slidably arranged on the side of the reinforcement plug hole 5, and a locking groove 28 matching the locking inclined plate 30 is opened on the side of the reinforcement plug rod 4. When the outer end of the reinforcement plug rod 4 abuts against the inner end of the reinforcement plug hole 5, the locking inclined plate 30 is stuck in the locking groove 28 to lock the reinforcement plug rod 4 to prevent the reinforcement plug rod 4 from sliding out, thereby automatically fixing the connection of the floor slab 1 again, facilitating operation and improving work efficiency.
