Abstract

The utility model provides a cushion block for molding mortar into a cover for reinforcement, which pertains to the field of construction material. The cushion block takes the shape of a rectangular hexahedron, and is characterized in that: a Y-axis arc groove (1) and a Z-axis arc groove(2) which is perpendicular to the Y-axis arc groove(1) are arranged on an X-axis plane CBFG of the rectangular hexahedron ABCDEFGH,; and an X-axis arc groove(3) is arranged on a Y-axis plane DCGH adjacent to the plane CBFG,; wherein depth of the Z-axis arc groove(2) is less than that of the Y-axis arc groove(1). The utility model is compact and delicate, and increases supplementary sizes of length, width and height between a bottom surface of an arc groove and a corresponding basic surface based on basic sizes of the length, the width and the height. By changing placement directions and reinforcement arrangement of products of the cushion block and base plates of buildings, the utility model can meet six different thickness requirements on a concrete cover for reinforcement. The utility model adopts a method of mechanical extrusion molding, achieves high production efficiency and produces high-quality products.

Description

A kind of reinforcement cover mortar moulding cushion block

Technical field

A kind of reinforcement cover mortar of the utility model moulding cushion block belongs to building material field, particularly mortar moulding material.

Background technology

In building operations; for guaranteeing that the cage of reinforcement in the steel concrete meets the positioning requirements of design; when disturbing concrete, do not produce displacement; so in the bottom of plate class A of geometric unitA and the bottom and the both sides of beam class A of geometric unitA; need to be arranged between the skeleton and template of reinforcing bar with the cushion block of given size; after guaranteeing fluid concrete, the outer thickness of concrete cover of the reinforcing bar that can meet design requirement.The present mortar cushion block that adopts, offhand is made, and intensity is low, and size is single, can not satisfy in the construction work the quality of different size cushion block and the demand of quantity.

The utility model content

The purpose of this utility model provides a kind of reinforcement cover mortar moulding cushion block; by the regulation position that the hexahedral relevant surface of basic length size is arranged to; be designed to the arc groove face; thereby on the basis of basic length size; increase replenishes size by the length that arc groove bottom surface and corresponding basic surface constitute; realizing that same cushion block product can satisfy the demand of six specifications, and can the extrusion modling processing.

The utility model purpose is achieved by the following technical solution:

The design's reinforcement cover mortar moulding cushion block; it is a rectangle hexahedron; it is characterized in that on the X axis surface C BFG of rectangle hexahedron ABCDEFGH; have a Y-axis to arc groove 1 with one with Y-axis to the vertical axial arc groove 2 of Z of arc groove 1; with the adjacent Y-axis in CBFG surface on surperficial DCGH; an X axis arc groove 3 is arranged, the degree of depth of the axial arc groove 2 of this Z less than Y-axis to arc groove 1.

The design's

arc groove

1,2,3 is vertical mutually at three dimensions, thus, on the basis of substantially hexahedral piece length size, corresponding having increased by arc groove bottom surface and the additional size of the available length between corresponding basic surface, can be by the placement direction and the reinforcing bar position of conversion the design hexahedron cushion block and building datum plate face, make between reinforcing bar and the building datum plate face, obtain six different spacing dimensions.Therefore can be in construction work, according to the engineering discipline requirement, by the placement direction and the reinforcement location of conversion the utility model cushion block and building datum plate face, to satisfy six kinds of various criterion thickness requirements of reinforced concrete protective layer.

The utility model design is succinct exquisite; on the basis of substantially hexahedral piece length size; corresponding having increased by the available length that is constituted between arc groove bottom surface and corresponding basic surface replenished size; placement direction and reinforcing bar setting by conversion the utility model cushion block product and building datum plate face; can satisfy six kinds of different-thickness requirements of reinforced concrete protective layer; the design's product adopts the mechanical presses moulding to produce production efficiency height, good product quality.

The specific embodiment

How now further specify the utility model in conjunction with the accompanying drawings implements:

According to present Standards for building industry, the Minimum Concrete Protective Coating Thickness regulation is respectively 15mm, 20mm, 25mm, 30mm, 35mm and 40mm.For satisfying the regulation of current standard, the basic size of the design's cushion block hexahedron ABCDEFGH as shown in Figure 1 is 25mm * 35mm * 40mm, the bottom surface of arc groove 1 as shown in Figure 3 is apart from CBFG surface 10mm, the degree of depth of arc groove 2 is less than arc groove 1 as shown in Figure 4, its bottom surface is apart from CBFG surface 5mm, the bottom surface of arc groove 3 has X axis through hole 4 apart from DCGH surface 5mm at the CBFG centre of surface as shown in Figure 2.

Setting building datum plate face is W, and the reinforcing bar that is positioned is S, wears steel wire from cushion block through hole 4, with cushion block and reinforcing bar binding.Extremely shown in Figure 10 as Fig. 5, the placement direction of conversion the utility model cushion block product and building datum plate face W and the position of reinforcing bar S, can with building datum plate face between obtain 15mm, 20mm, 25mm, 30mm, 35mm and six different spacing dimensions of 40mm successively.Therefore can be in construction work; according to the engineering specification code requirement; by the placement direction of conversion the design cushion block and building datum plate face and the position of reinforcing bar S, satisfy six kinds of respective thickness requirements of 15mm, 20mm, 25mm, 30mm, 35mm and the 40mm of reinforced concrete protective layer.

Specification of the present utility model is that the utility model is not limited thereto specification at the current standard design.
