Description

Technical Field

[0001] The utility model relates to a protective device for preventing pollution of exposed anchoring steel bars of a pile core steel bar cage, belonging to the technical field of building construction. Background Art

[0002] In the construction of prestressed pipe pile foundations in foundation pit projects of construction projects, due to the needs of the process, the core of the pipe pile needs to be reinforced with a steel cage and poured with concrete. After the concrete pouring of the core is completed, the steel cage has exposed steel bars for anchoring to the foundation cap. Before the foundation cap is poured, the anchor steel bars are exposed and unprotected. During the pouring of the core concrete and the construction of the waterproof protective layer, the anchor steel bars are easily contaminated by the concrete, making the surface slurry difficult to clean. If contaminated, it must be thoroughly cleaned, which requires a lot of manpower and material resources, and it is difficult to ensure the quality of the cleaning, which reduces the bond strength between the anchor steel bars and the cap concrete, affecting the construction quality.

[0003] The present application aims to solve the above-mentioned problems.

[0004] In order to be more targeted in solving the above problems, we conducted relevant searches to find patent documents that are strongly related to this application. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to implement anti-pollution protection for the exposed anchoring steel bars of the pile core steel cage before the construction of the foundation.

[0006] In view of the above problems, the technical solution proposed by the utility model is:

[0007] A protective device for preventing the exposed anchor steel bars of a pile core steel cage from being contaminated, comprising a sleeve and a chain belt. There are multiple sleeves, which are equally spaced and bound on the chain belt. When used, each sleeve can be sleeved outside an anchor steel bar to prevent concrete slurry from adhering to the outer periphery of the anchor steel bar.

[0008] Furthermore, the top end of the sleeve has a blocking piece for blocking the top end pipe opening.

[0009] Furthermore, it also includes a binding belt, which binds the sleeve to the chain belt.

[0010] Furthermore, a limiting collar is sleeved and fixed on the upper section of the sleeve, and the restraining belt is restrained on the sleeve below the limiting collar.

[0011] Furthermore, the chain belt is made of a flexible material, and a tensioning rod is provided inside the chain belt for shortening the chain belt longitudinally.

[0012] Furthermore, the number of the sleeves is greater than or equal to the number of the anchoring steel bars. Beneficial Effects

[0013] 1. When pouring concrete into the pile core, it is possible to prevent the anchor steel bars from being stained with concrete slurry, thus eliminating the waste of labor costs caused by subsequent cleaning;

[0014] 2. Simple structure and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings: Embodiment 1

[0021] like Figure 1 As shown in FIG. 4 , a protective device for preventing the exposed anchor steel bars of the pile core reinforcement cage from being contaminated comprises a sleeve 1 and a chain belt 2. The sleeve 1 is provided in plurality and is equally spaced and bound to the chain belt 2. When used, each sleeve 1 can be sleeved outside an anchor steel bar to prevent the concrete slurry from adhering to the outer periphery of the anchor steel bar. In this way, when pouring concrete into the pile core, the concrete slurry can be prevented from adhering to the anchor steel bar, thereby eliminating the waste of labor costs caused by subsequent cleaning.

[0022] The top end of the sleeve 1 is provided with a plugging piece 101 for plugging the top end pipe opening, so that the sleeve 1 sleeved on the anchoring steel bar will not slide down, and concrete slurry can be prevented from flowing from the upper end to the anchoring steel bar.

[0023] Furthermore, it also includes a binding belt 3, which binds the sleeve 1 to the chain belt 2, so that the sleeves 1 can be prevented from scattering, and the sleeves 1 can be pulled out together.

[0024] The upper section of the sleeve 1 is sleeved and fixed with a limiting collar 4, and the restraining belt 3 is restrained on the sleeve 1 below the limiting collar, so that the restraining belt 3 can be prevented from slipping out upward when the sleeve 1 is pulled out by pulling the chain belt 2.

[0025] The number of the sleeves 1 is equal to the number of the anchoring steel bars, and the number of the sleeves 1 can also be more than the number of the anchoring steel bars, which can be used when the number of anchoring steel bars increases. Embodiment 2

[0026] like Figure 2 As shown in FIG. 4 , the difference from the first embodiment is that the chain belt 2 is made of a flexible material, and a tensioning rod 5 is provided inside the chain belt 2 for shortening the chain belt 2 longitudinally, so that the chain belt can be tightened by tightening the tensioning rod 5 when in use.

[0027] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the protection scope of the present invention. Any modifications in equivalent forms should be regarded as falling within the protection scope of the present invention.
