Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a novel sleeve type steel bar protective layer pad. Background Art

[0002] When pouring reinforced concrete, it is necessary to place a spacer between the formwork and the steel mesh, so that there is a distance between the steel mesh and the formwork. After pouring the concrete, a steel protection layer is formed outside the steel mesh. The thickness of the steel protection layer is controlled by the height of the spacer. Whether the thickness of the protection layer meets the design requirements will directly affect the stress and durability of the component.

[0003] At present, during construction, pads are usually tied on the outside of the steel mesh to limit the distance between the steel mesh and the formwork. The stability of the tied pads is relatively low, and they are easily dislocated or even fallen due to external vibrations in the later stage, causing the problem of exposed reinforcement in the later stage.

[0005] The utility model discloses a novel sleeve type steel bar protective layer pad, comprising a cubic concrete block. A pre-embedded rod is arranged on one side of the cubic concrete block. A sleeve is arranged on the exposed end of the pre-embedded rod. A card interface is opened on the sleeve. Both ends of the card interface are connected by bolts.

[0006] Preferably, a gasket is provided at the exposed end of the embedded rod, one side of the gasket is in close contact with the cubic concrete block, and the other side is integrally formed with the ferrule.

[0007] Preferably, a threaded sleeve is pre-embedded in the cubic concrete block, and the pre-embedded rod is threadedly connected in the threaded sleeve.

[0008] Preferably, a mounting hole penetrating the gasket is provided on the inner ring wall of the ferrule, and the exposed end of the embedded rod passes through the mounting hole and is fixed to the polygonal anti-drop cap.

[0009] Preferably, the exposed end of the embedded rod is fixed to the gasket by welding.

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment 1

[0020] like Figure 1 As shown, this embodiment discloses a novel sleeve type steel bar protective layer pad, including a cubic concrete block 1, a side surface of the cubic concrete block 1 is provided with an embedded rod 2, the exposed end of the embedded rod 2 is provided with a sleeve 3, a card interface 301 is opened on the sleeve 3, and the two ends of the card interface 301 are connected by bolts 4.

[0021] In this embodiment, a gasket 302 is provided at the exposed end of the embedded rod 2, and the gasket 302 and the ferrule 3 are both made of metal, one side of the gasket 302 is in close contact with the cubic concrete block 1, and the other side is integrally formed with the ferrule 3. The gasket 302 can effectively improve the stability of the ferrule 3.

[0022] In this embodiment, the embedded rod 2 is detachably connected to the cubic concrete block 1. Specifically, a threaded sleeve 5 is embedded in the cubic concrete block 1, and the embedded rod 2 is threadedly connected to the threaded sleeve 5. The embedded rod 2 is detachably connected to the threaded sleeve 5, so that cubic concrete blocks 1 of different sizes can be replaced. In order to improve the firmness of the connection between the threaded sleeve 5 and the cubic concrete block 1, a plurality of protrusions 501 can be provided on the outer wall of the threaded sleeve 5.

[0023] At the same time, in this embodiment, the embedded rod 2 is also detachably connected to the ferrule 3. Specifically, a mounting hole 303 penetrating the gasket 302 is provided on the inner ring wall of the ferrule 3. The exposed end of the embedded rod 2 penetrates the mounting hole 303 and is welded and fixed to the polygonal anti-drop cap 201. During installation, after the lower end of the embedded rod 2 penetrates the mounting hole 303, the anti-drop cap 201 is twisted with a wrench to fix the ferrule 3 on the cubic concrete block 1.

[0024] like Figure 2 As shown, the use principle of the utility model is: the clamping sleeve 3 is clamped on the steel mesh 6 through the clamping interface 301, and then a template 7 is supported around the steel mesh 6, and the cubic concrete block 1 is against the template 7.

[0025] Embodiment 2

[0026] like Figure 3 As shown, the exposed end of the embedded rod 2 in this embodiment is welded and fixed to the gasket 302, and the remaining structure of the gasket in this embodiment is the same as that in the first embodiment.
