Description

Technical Field

[0001] This utility model relates to the field of concrete embedded part installation technology, specifically a telescopic fixing device for cast-in-place concrete embedded parts. Background Technology

[0002] Steel structures, equipment bases, and other components installed on civil engineering projects are often reliably connected to the civil engineering projects using embedded parts. As the key carriers connecting the upper steel structure and equipment base, the installation position accuracy of the embedded parts directly affects the quality of subsequent equipment installation.

[0003] Traditional embedded parts are fixed by welding or binding. When the distance between the embedded part and the positioning steel bar is large, the support needs to be cut / bent on site, which damages the structural strength. Moreover, the impact of concrete vibration can easily cause the weld to crack and the embedded part to be displaced beyond the tolerance (the installation position of the embedded part is large, which makes the subsequent installation of the upper components or equipment difficult, requiring remedial measures or rework, affecting the construction progress). Therefore, this utility model provides a telescopic fixing device for embedded parts in cast-in-place concrete. Utility Model Content

[0004] To address the problem of difficulty in fixing embedded parts when there is a deviation between the embedded parts and the positioning reinforcement, this utility model provides a telescopic fixing device for embedded parts in cast-in-place concrete.

[0035] Please refer to the attached document. Figures 1-6 This application illustrates a telescopic fixing device for embedded parts in cast-in-place concrete, which is used to stably fix the embedded parts when there is a deviation between the embedded parts (referring to the embedded steel bars 2 and embedded steel plates 1 below) and the positioning steel bars. Specifically, it includes: a fixedly installed positioning steel bar 4, embedded steel bars 2, embedded steel plates 1, and telescopic fixing components 3.

[0036] The bottom of the pre-embedded steel plate 1 is fixedly connected with pre-embedded steel bars 2, which are generally installed by full welding or thread. The pre-embedded steel bars 2 and the positioning steel bars 4 are connected by expansion and contraction fixing components 3.

[0037] The telescopic fixing component 3 is used to compensate for the deviation between the embedded part and the positioning steel bar 4. According to the actual deviation, the telescopic fixing component 3 is adjusted to a suitable length, which can achieve efficient and accurate fixing of the embedded part and solve the problem of reliable and stable connection between the embedded part and the positioning steel bar 4.

[0038] In a specific embodiment, the telescopic fixing member 3 includes: a first body 301 and a second body 304.

[0039] The first main body 301 has a first annular connector 302 fixedly connected to its first end, and a plug rod 303 fixedly connected to its second end. Generally, the first main body 301, the first annular connector 302, and the plug rod 303 are integrated. The first annular connector 302 is used to connect the positioning steel bar 4. The second main body 304 has a second annular connector 305 fixedly connected to its first end, and a socket 306 that mates with the plug rod 303 is opened at its second end. The plug rod 303 is slidably inserted into the socket 306, which can realize the sliding extension and retraction adjustment of the overall length of the first main body 301 and the second main body 304. The second annular connector 305 is used to connect the embedded steel bar 2.

[0040] In one embodiment, in order to prevent the first body 301 and the second body 304 from sliding apart, a sliding groove is provided on the top of the insertion rod 303, and both ends of the sliding groove are closed ends. A frame opening 307 is provided on the inner top of the insertion port 306, and a locking block 308 is provided inside the frame opening 307. The frame opening 307 corresponds to the sliding groove.

[0041] like Figure 5 , Figure 6 As shown, the locking block 308 falls under the action of gravity and gets stuck in the sliding groove. Within the limited length of the sliding groove, the insertion rod 303 and the insertion port 306 can slide freely. When it slides to the end of the sliding groove, the closed end of the sliding groove abuts against the locking block 308, thereby restricting the sliding of the insertion rod 303 and the insertion port 306. This can prevent the insertion rod 303 from sliding out of the insertion port 306 (separation of the first body 301 and the second body 304).

[0042] In one embodiment, multiple sets of positioning reinforcing bars 4, embedded reinforcing bars 2, and expansion joints 3 are provided, such as... Figure 1 , Figure 2 As shown, the positioning steel bar 4, the pre-embedded steel bar 2, and the expansion fixing component 3 are all provided with four sets. Specifically, three sets, six sets, twelve sets, etc. can be provided, depending on the actual design requirements.

[0043] In one embodiment, a connecting member 5 is provided on the top of the embedded steel plate 1. The connecting member 5 can be a connecting column or a mounting hole to facilitate the installation of the embedded steel plate 1 with the upper component or equipment.

[0044] In one embodiment, the bottom end of the embedded steel bar 2 is provided with a hook 2a, which is used to increase the tensile strength of the embedded steel bar 2 and ensure that the embedded parts (referring to the embedded steel bar 2 and the embedded steel plate 1) have sufficient strength.
