Description

Technical Field

[0001] The utility model belongs to the technical field of building accessories, and particularly relates to a pre-buried screw rod which is more firmly buried. Background Art

[0002] Embedded parts are very important in building construction. They have embedded sections embedded in concrete and exposed sections exposed on the ground. During construction, the embedded sections are placed in unsolidified concrete. After the concrete solidifies, the embedded sections are firmly connected to the concrete, and the exposed sections are used to install mechanical components on the ground.

[0003] The embedded screw rod is a common embedded part. The current embedded screw rod has a simple structure. Specifically, it consists of a bent rod embedded in the concrete and a screw rod exposed on the ground. The connection with the concrete only relies on the bent rod.

[0004] However, in the actual construction process, due to factors such as load changes, environmental changes, and foundation settlement, faults are easily generated inside the concrete. The existing pre-embedded random dry bent rod is a hard rod. When deformation occurs inside the concrete, the bent rod is easily broken, thereby weakening the connection force between the pre-embedded screw and the concrete, greatly reducing the embedding firmness of the pre-embedded screw in the concrete, and sometimes even causing the screw exposed on the ground to fall off from the concrete. Utility Model Content

[0039] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0040] Example:

[0041] like Figures 1-6 As shown, the embedded screw provided by this embodiment comprises a first plate body 100, a bent rod 200, a screw rod 300, a second plate body 400 and an embedded rope 700. The bent rod 200 and the screw rod 300 are integrally formed and fixed on the two side surfaces of the first plate body 100. The bent rod 200 and the first plate body 100 are used to be embedded in concrete, the screw rod 300 is exposed outside the concrete, and the second plate body 400 is detachably fixed to the first plate body 100 through a locking assembly. A plate body 100, and a second plate body 400 is stacked with the first plate body 100. In this embodiment, the screw rod 300 is located on the upper surface of the first plate body 100, the bending rod 200 is provided on the lower surface of the first plate body 100, the second plate body 400 is placed on the upper surface of the first plate body 100, and the embedded rope 700 is fixed to the bottom surface of the second plate body 400. The embedded rope 700 is located on the side of the bending rod 200, and the embedded rope 700 is used to be buried in concrete.

[0042] The above-mentioned embedded screw connects the second plate body 400 and the first plate body 100 together with the help of a locking assembly. In this way, the embedded rope 700, the second plate body 400, the first plate body 100, the bent rod 200 and the screw 300 form a whole. When in use, the embedded rope 700, the first plate body 100 and the bent rod 200 are buried in the concrete together, so that the bent rod 200 is exposed outside the concrete. When the concrete is dry and solidified, the bent rod 200 of the embedded screw, the first plate body 100 and the embedded rope 700 are all tightly connected to the concrete, so that the embedded screw is more firmly embedded in the concrete. When the concrete has a fault, even if the bent rod 200 breaks, the first plate body 100 and the embedded rope 700 will not be affected by the fault. In particular, the embedded rope 700 has a certain flexibility and can better adapt to the faulted concrete, so that the embedded screw is more firmly connected to the concrete.

[0043] Optionally, the first plate 100 is a circular steel plate, and the screw rod 300 and the bent rod 200 are integrally formed with the first plate 100 by casting, with the bent rod 200 and the screw rod 300 both located at the center of the first plate 100. The second plate 400 is also a circular steel structure, with a through hole 431 adapted for the screw rod 300 defined at the center of the second plate 400. The screw rod 300 is inserted into the through hole 431, and the second plate 400 is overlapped on the top surface of the first plate 100.

[0044] The above-mentioned locking assembly includes a stud 500 and a nut 600. The stud 500 is welded and fixed on the top surface of the first plate body 100, that is, the stud 500 and the screw 300 are located on the same side plate surface of the first plate body 100. A through hole 432 is opened on the second plate body 400, and the position of the through hole 432 corresponds to the above-mentioned stud 500. The above-mentioned stud 500 passes through the above-mentioned through hole 432 and is screwed with the above-mentioned nut 600. When the nut 600 is tightened, the nut 600 presses the second plate body 400 on the top surface of the first plate body 100 to lock the second plate body 400 to the first plate body 100. Optimally, there are multiple studs 500, which are evenly distributed around the screw rod 300, and there are multiple through holes 432 and nuts 600. Multiple studs 500 correspond one-to-one with multiple through holes 432 and multiple nuts 600, thereby more firmly connecting the second plate body 400 to the first plate body 100.

[0045] Of course, the second plate body 400 may also be connected to the first plate body 100 by welding, in which case the locking assembly is not required.

[0046] An optional implementation of this embodiment is as follows: the second plate body 400 includes an annular plate 410, a tube body 420 and a sealing plate 430, wherein:

[0047] The annular plate 410 is a steel annular structure, and one end of the embedded rope 700 is fixedly connected to the annular plate 410. The tube body 420 is fixedly arranged in the inner ring hole of the annular plate 410. The tube body 420 is coaxially arranged with the annular plate 410, and one end of the tube body 420 is flush with one side plate surface of the annular plate 410, and the other end of the tube body 420 extends out of the inner ring hole of the annular plate 410. The sealing plate 430 is arranged at the other end of the tube body 420 and blocks the tube body 420. The through hole 431 and the through hole 432 are both opened in the sealing plate 430. The sealing plate 430 is in contact with the first plate 100, and the stud 500 and the nut 600 are both accommodated in the tube body 420. Optionally, the annular plate 410, the tube body 420 and the sealing plate 430 in this embodiment are integrally formed by casting. Optionally, the above-mentioned embedded rope 700 is a steel wire rope, one end of which is welded and fixed to the annular plate 410, and there are multiple steel wire ropes, which are evenly distributed around the tube body 420.

[0048] The above-mentioned sealing plate 430 is located below the annular plate 410. When installed in concrete, the top surface of the above-mentioned annular plate 410 is flush with the surface of the concrete. At this time, the tube body 420 and the sealing plate 430 form a concave groove, and the above-mentioned stud 500 and nut 600 are built into the above-mentioned groove, which can prevent the stud 500 and nut 600 from protruding from the ground.

[0049] More preferably, the embedded screw provided in this embodiment further includes a protective cover 800 or a blocking block.

[0050] Specifically, when the screw 300 is not needed to connect components, the screw 300 is protected by a protective cover 800. In this case, the protective cover 800 is screwed onto the screw 300 and covers the screw 300. A sealing gasket 900 is bonded and fixed to the end wall of the protective cover 800. When the protective cover 800 is tightened onto the screw 300, the sealing gasket 900 is installed between the end wall of the protective cover 800 and the second plate 400, which not only protects the screw 300 but also effectively prevents water from entering the groove. To prevent pedestrians from being bumped by the protruding protective cover 800, in this embodiment, a fluorescent film is provided on the outer wall of the protective cover 800 to help people notice the protective cover 800 in the dark, and thus notice the embedded screw protruding from the ground.

[0051] When the screw 300 is needed to connect components, the protective cover 800 is first removed. A blocking block is then placed over the screw 300 and pressed down into the groove. The blocking block is tightly attached to the groove wall (i.e., the inner wall of the tube body 420), thereby sealing the groove opening with the blocking block. The blocking block can be a rubber block. Of course, concrete can also be poured into the groove instead of the blocking block.

[0052] An optional implementation of this embodiment is as follows: a plurality of rigid rods 110 are further welded to the first plate 100. The rigid rods 110 and the studs 500 are respectively located on both sides of the first plate 100. The rigid rods 110 are also curved and are also embedded in the concrete, thereby making the embedded screws provided in this embodiment more securely connected to the concrete.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
