Description

Technical Field

[0001] The utility model relates to an embedded component, in particular to a civil engineering steel structure embedded component. Background Art

[0002] Generally, when doing civil engineering or foundation, in order to facilitate the installation of structures or equipment on the foundation in the future, the base of part of the equipment or the auxiliary steel plate structure is placed on the foundation in advance. After the work is completed, the subsequent equipment can be easily fixed on the embedded parts. Common embedded parts in engineering include flat embedded parts and through-embedded parts.

[0003] Among them, the embedded parts are also called tension embedded parts or plywood embedded parts, which are often used in the concrete structure of the civil engineering of buildings. The function of the embedded parts is to connect the concrete components to each other and withstand the shear force, torsion force, tensile force and other forces in different directions between the joint surfaces.

[0004] The embedded parts currently in use are made by welding two steel plates together in parallel through several steel bars of the same length; welding increases the connection strength between the steel plates and the steel bars; however, in the actual process of making the embedded parts, fusion welding consumes part of the material at the end of the steel bars, causing the length of the steel bars to be slightly shortened after fusion welding; and the length loss caused by fusion welding is uncontrollable.

[0005] In order to reduce the length loss of steel bars, the degree of molten welding should be reduced in theory. However, in actual operation, if the welding is not sufficient, there will be a problem of cold welding, resulting in insufficient connection strength between the steel bars and the steel plates. It is precisely because the embedded parts are connected by welding multiple steel bars, and the length loss of each steel bar during the welding process cannot be guaranteed to be completely consistent, so the two steel plates on the final embedded parts are not absolutely parallel.

[0006] For this reason, some production personnel use bolt connections to connect the steel bars and steel plates; however, during the concrete pouring and vibration process, the bolted steel bars and steel plates may become loose. Utility Model Content

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0040] See also Figures 1 to 12 As an embodiment of the utility model, the civil engineering steel structure embedded part comprises two steel plates 1 which are arranged parallel to each other and corresponding to each other, and the two steel plates 1 are connected by a plurality of steel bars 3;

[0041] A fixing sleeve 2 is fixedly provided on one side opposite to the two steel plates 1 , and the fixing sleeve 2 is connected to the end of the steel bar body 3 by a quick riveting structure.

[0042] In this embodiment, since the fixing sleeve 2 and the steel bar body 3 are connected by a quick riveting structure, and the fixing sleeve 2 is fixed on the steel plate 1, the two ends of the steel bar body 3 can be quickly and firmly connected to the two steel plates 1.

[0043] During the whole connection process, there is no loss of the steel bar body 3 as a whole, so the size and shape of the embedded parts after forming are highly consistent with the designed size and shape. The steel plate 1 and the steel bar body 3 are connected together by assembly, which can be connected and fixed, and can also be disassembled and replaced, avoiding material waste due to material matching errors.

[0044] As a further solution of the utility model, the quick riveting structure includes a first insertion channel 201 and a second insertion channel 202 arranged in the fixing sleeve 2, wherein the first insertion channel 201 passes through one end of the fixing sleeve 2, the second insertion channel 202 passes through the other end of the fixing sleeve 2, and an outer cone step 203 is formed between the first insertion channel 201 and the second insertion channel 202;

[0045] The end of the steel bar body 3 and the outer cone step 203 are riveted to each other.

[0046] In this embodiment, the outer cone step 203 formed between the first insertion channel 201 and the second insertion channel 202 is connected to the end of the steel bar body 3 to form a riveted connection relationship, which can maintain the connection strength between the steel bar body 3 and the fixing sleeve 2 and meet the use requirements of the integral embedded parts; and during the entire connection process, welding is not required, and the connection speed is faster.

[0047] As a further solution of the present invention, the steel bar body 3 includes a steel bar body and connecting parts 301 integrally arranged at both ends of the steel bar body;

[0048] An end cap 302 is integrally formed at one end of the connection portion 301 away from the main body of the steel bar, an inner cone step 304 is formed between the end cap 302 and the connection portion 301, and the inner cone step 304 is adapted to the outer cone step 203;

[0049] An inner seam 305 is formed in the center of the connection portion 301 , and the inner seam 305 passes through an end of the connection portion 301 away from the main body of the steel bar.

[0050] In this embodiment, an inner cone step 304 is formed between the end 302 and the connecting portion 301. The inner cone step 304 can be regarded as a hook facing the steel bar body, while the outer cone step 203 can be regarded as a hook facing away from the steel bar body. The two cooperate with each other to form a riveted structure similar to a barb, and the connection is very stable.

[0051] Because the inner seam 305 is provided on the connecting portion 301, when the end head 302 is inserted into the first insertion channel 201, an extrusion force is applied to the end head 302 through the inner wall of the first insertion channel 201, so that the end head 302 shrinks; once the end head 302 passes through the first insertion channel 201 and enters the second insertion channel 202, since the inner diameter of the second insertion channel 202 is larger than the inner diameter of the first insertion channel 201, the shrunk end head 302 will be reset and expanded to expand the inner cone step 304. The expanded inner cone step 304 is constrained by the outer cone step 203, so that the connecting portion 301 cannot be pulled out of the fixing sleeve 2.

[0052] As a further solution of the utility model, the outer edge of the end cap 302 away from the steel bar body is formed with an inclined conical surface 303, and the inner edge of the first insertion channel 201 close to the steel bar body is formed with an inner inclined conical chamfer, and the inner inclined conical chamfer is adapted to the inclined conical surface 303.

[0053] In this embodiment, the inner oblique cone chamfer cooperates with the oblique cone surface 303, so that the end 302 has less resistance and less wear during the insertion of the end 302 into the first insertion channel 201, and it is also more conducive to smoothly inserting the connecting part 301 into the fixing sleeve 2.

[0054] As a further solution of the utility model, the steel plate 1 is provided with an internal thread countersunk hole 101, and an external thread cylinder 4 is threadedly connected in the internal thread countersunk hole 101, and the external thread cylinder 4 is coaxial with the steel bar body 3;

[0055] A pin piece 401 is integrally fixedly provided at the center of one end of the external threaded cylinder 4 facing the steel bar body.

[0056] In this embodiment, at the moment when the inner cone step 304 completely passes through the first insertion channel 201 and enters the second insertion channel 202, the inner cone step 304 is not completely in contact with the outer cone step 203, and there is a gap between the two; therefore, the steel bar body 3 after the initial connection is able to move slightly in the fixing sleeve 2.

[0057] In order to increase the stability of the connection between the steel bar body 3 and the fixing sleeve 2, an externally threaded cylinder 4 is added in the present application; when the inner conical step 304 completely passes through the first insertion channel 201 and enters the second insertion channel 202, the connecting portion 301 is pushed further into the fixing sleeve 2, so that the pin piece 401 is inserted into the inner seam 305, and then the steel bar body 3 is rotated, and the pin piece 401 is driven to rotate through the inner seam 305 to rotate the externally threaded cylinder 4; the externally threaded cylinder 4 cooperates with the internally threaded countersunk hole 101, so that the externally threaded cylinder 4 continuously approaches the end head 302 during the rotation process until it fits with the end head 302, and squeezes the inner conical step 304 to fit into the outer conical step 203, so that the two are completely fitted.

[0058] As a further solution of the utility model, top holes are symmetrically opened on both sides of the fixing sleeve 2, and the internal threads of the top holes are matched with top screws 5, and the top screws 5 are directly opposite to the outer edge of the end head 302.

[0059] In this embodiment, when the steel bar body 3 with mismatched specifications is installed in the fixing sleeve 2 due to material matching error, the steel bar body 3 can be rotated in the opposite direction first, and the pin piece 401 can be driven to reverse through the inner shrinkage seam 305, so that the external threaded cylinder 4 rotates in the opposite direction and keeps moving away from the end head 302, so as to restore the clearance between the external threaded cylinder 4 and the end head 302; then, the top shrinkage screws 5 on both sides are screwed in, and the top shrinkage screws 5 squeeze the outer edge of the end head 302 to shrink the end head 302 inwardly; during the process of the end head 302 shrinking inwardly, the inner cone step 304 interacts with the outer cone step 203, so that the end head 302 shrinks inwardly while approaching the external threaded cylinder 4, and the details can be referred to. Figure 8 , and finally the inner cone step 304 is separated from the outer cone step 203; after the inner cone step 304 is separated from the outer cone step 203, the end head 302 remains in a contracted state under the action of the retraction screws 5 on both sides, and the connecting part 301 can be pulled out of the fixing sleeve 2 at this time.

[0060] As a further solution of the utility model, the connecting portion 301 and the steel bar main body support form an outer oblique cone chamfer, the outer oblique cone chamfer is adapted to the inner oblique cone chamfer, and when the inner cone step 304 is riveted to the outer cone step 203, a disassembly gap is formed between the outer oblique cone chamfer and the inner oblique cone chamfer.

[0061] In this embodiment, the disassembly and assembly gap has two functions. On the one hand, when the connecting portion 301 is inserted into the fixing sleeve 2, there is a gap between the two at the moment when the inner cone step 304 completely passes through the first insertion channel 201 and enters the second insertion channel 202, and the disassembly and assembly gap provides expansion space for the gap.

[0062] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
