Description

Technical Field

[0001] The utility model relates to an auxiliary tool for building construction, in particular to a steel bar protection layer cushion block. Background Art

[0002] Existing measures to ensure the steel bar protection layer include concrete supporting rods, ladder-shaped steel bars, and plastic clips. Generally, positioning hoops are used for frame columns to ensure the position of steel bars and the thickness of the steel bar protection layer.

[0003] The above methods have problems of being unable to construct and inconvenient construction. For example, the concrete supporting rods are generally 200 mm long for 200-mm-thick walls and cannot be used for walls with thicknesses of 300 mm, 350 mm, and 400 mm that often appear at the construction site; the ladder-shaped steel bars and positioning hoops need to be welded with steel bars and need to be turned over during the construction process, and the construction is relatively complicated; the plastic clips are easy to fall off during the formwork closing process and have low strength, which is not conducive to ensuring the thickness of the steel bar protection layer. Summary of the Invention

[0004] The utility model provides a steel bar protection layer cushion block to solve the problems of being unable to construct and inconvenient construction existing in the measures taken for the previous steel bar protection layer.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a steel bar protection layer cushion block, including a spring steel sheet and a rubber outer sleeve. The spring steel sheet is in a shape similar to a "U", and the steel sheets on both sides of the open end of the spring steel sheet incline towards the center to form a clamping end; the rubber outer sleeve is wrapped outside the spring steel sheet, and the outer shape of the rubber outer sleeve is generally the same as and matches the outer shape of the spring steel sheet, except that the clamping surface inside the clamping end of the rubber outer sleeve is an arc surface.

[0006] Further, a flat clamping flaring is provided at the entrance of the clamping end of the rubber outer sleeve, and the size of the clamping flaring gradually decreases from outside to inside.

[0007] Furthermore, the spring steel sheet is made of spring steel.

[0008] Further, the rubber outer sleeve is made of synthetic rubber.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The use of the cushion block and support method of the utility model realizes the effects of convenient construction and effective guarantee of construction quality. Since the cushion block of the utility model adopts a pressing and clamping method, the construction operation is simple, and the cushion block is applicable to walls of any thickness and frame columns, beams, and slab members with any cross-sectional dimensions, and has strong applicability.

[0014] The following further illustrates the utility model in conjunction with specific embodiments. Embodiment

[0015] As Figure 1 shown, a steel bar protection layer spacer block includes a spring steel sheet 1 and a rubber outer sleeve 2. The spring steel sheet 1 is in a shape similar to a "U". The steel sheets on both sides of the open end of the spring steel sheet 1 incline towards the center to form a clamping end. The rubber outer sleeve 2 is wrapped outside the spring steel sheet 1. The outer shape of the rubber outer sleeve 2 is generally the same as and matches the outer shape of the spring steel sheet 1, except that the clamping surface inside the clamping end of the rubber outer sleeve 2 is an arc surface.

[0016] Furthermore, a flat clamping flaring is provided at the entrance of the clamping end of the rubber outer sleeve 2, and the size of the clamping flaring gradually shrinks from outside to inside. The design of the clamping flaring facilitates the steel bar protection layer spacer block

[0017] Furthermore, the spring steel sheet 1 is made of spring steel.

[0018] Furthermore, the rubber outer sleeve 2 is made of synthetic rubber.

[0019] Working principle and operation method: The steel bar protection layer spacer block is composed of a spring steel sheet 1 and a rubber outer sleeve 2. Align the clamping end of the spacer block with the outermost steel bar and clamp it on the outermost steel bar. By pressing the spacer block, since the spring steel sheet 1 can be further deformed, the spacer block can be more firmly clamped on the outermost steel bar. The layout of the spacer blocks is the same as that of ordinary spacer blocks according to the specification requirements. The steel bars are separated from the formwork through the spacer blocks, thereby realizing the control of the steel bar protection layer. Since the spacer block adopts the method of pressing and clamping, the construction operation is simple. The spacer block is applicable to walls of any thickness and frame columns, beams, and slab members with any cross-sectional dimensions.
