Description

Technical Field

[0001] The utility model relates to the technical field of cushion blocks, in particular to an anti-dislocation steel bar protective layer cushion block. Background Art

[0002] Steel bar protective layer pads, also known as concrete pads, are indispensable structural parts in construction projects. When in use, the steel bar protective layer pads are placed under the steel bars to expand the bearing area of ​​the steel bars and solve the problem of local bearing. At the same time, the steel bar concrete protective layer has the functions of preventing erosion, heat insulation, and strengthening the ability to withstand external forces, thereby maximizing the optimal strength of the building structure and extending its service life. Traditional steel bar protective layer pads are square blocks with positioning grooves on the top surface that match the steel bars. When in use, the steel bars are placed in the positioning grooves. However, since the positioning of the steel bar protective layer pads and the steel bars is not firm, the steel bar protective layer pads are prone to displacement and missing, which affects the construction effect. Summary of the invention

[0003] In order to solve the problem that the traditional steel bar protection layer pad is prone to deviation and loss, the utility model provides a new anti-dislocation steel bar protection layer pad.

[0004] The utility model is realized by adopting the following technical solutions:

[0005] A dislocation-proof steel bar protective layer pad comprises an upper pad body, a lower pad body, and four C-shaped spring clips. The upper pad body and the lower pad body are spliced ​​up and down to form a columnar pad whose axial arrangement direction is the front-to-back direction. The bottom surface of the upper pad body and the top surface of the lower pad body are respectively provided with an upper semicircular steel bar positioning groove and a lower semicircular steel bar positioning groove, both of which are arranged axially along the front-to-back direction. The upper semicircular steel bar positioning groove and the lower semicircular steel bar positioning groove form a through-bar hole adapted to the steel bar. The bottom surface of the upper pad body is provided with an upper tenon and / or upper groove, the top surface of the lower pad body is provided with a lower groove and / or a lower tenon matched with the upper tenon and / or upper groove, the front side and the rear side of the columnar pad are provided with two C-shaped grooves whose length arrangement directions are both in the up and down directions, the upper end and the lower end of each C-shaped groove are respectively distributed on the upper pad body and the lower pad body, the two C-shaped grooves located on the same side of the columnar pad are symmetrically arranged on the left and right sides of the rib hole, and the four C-shaped spring clips are respectively clamped in the four C-shaped grooves to realize the fixed connection between the upper pad body and the lower pad body.

[0006] Working principle: The steel bar protective layer pad realizes the combination and positioning of the upper pad body and the lower pad body through the structural design of tenons and grooves, and realizes the fixed connection between the upper pad body and the lower pad body through the structure of C-shaped spring clip. This structure is easy to install and can effectively avoid the deviation and loss of the steel bar protective layer pad, thereby ensuring the construction effect.

[0007] Furthermore, a circular load-bearing iron cylinder with an inner diameter matching the steel bar is sleeved in the reinforcement hole. The circular load-bearing iron cylinder is composed of two semicircular iron plates. The joint surfaces of the two semicircular iron plates are staggered with the joint surfaces of the upper pad body and the lower pad body to prevent the upper pad body from separating from the lower pad body when the force is large.

[0008] Furthermore, an upper tenon and an upper groove are provided on the main body of the upper pad, and the upper tenon and the upper groove are arranged symmetrically about the upper semicircular steel bar positioning groove. The lower pad main body is provided with a lower groove and a lower tenon matched with the upper tenon and the upper groove, respectively. The structure is concretized and standardized, which improves the overall stability of the steel bar protective layer pad.

[0009] Furthermore, the cross section of the columnar pad is polygonal. Compared with the columnar pad with a circular cross section, this structure increases the contact area between the steel bar protective layer pad and the formwork.

[0010] Furthermore, the main body of the upper pad block is an isosceles trapezoid that is narrow at the top and wide at the bottom, and the main body of the lower pad block is an isosceles trapezoid that is wide at the top and narrow at the bottom. The columnar pad formed by splicing the upper pad block main body and the lower pad block main body up and down is a columnar pad with a regular hexagonal cross-section, and the structure is concretized and standardized.

[0011] The beneficial effects produced by the utility model are as follows: the utility model cleverly realizes the combination and positioning of the upper pad block body and the lower pad block body through the structural design of the tenon and groove, and realizes the fixed connection between the upper pad block body and the lower pad block body through the structure of the C-shaped spring clip. This structure is easy to install and can effectively avoid the deviation and missing of the steel bar protective layer pad, thereby ensuring the construction effect.

The upper semicircular steel bar positioning groove and the lower semicircular steel bar positioning groove form a through-bar hole 4 adapted to the steel bar. The bottom surface of the upper pad body 1 is provided with an upper tenon and / or upper groove, the top surface of the lower pad body 2 is provided with a lower groove 5 and / or a lower tenon 6 matched with the upper tenon and / or upper groove, the front side and the rear side of the columnar pad are provided with two C-shaped grooves 7 whose length arrangement directions are both in the up and down directions, the upper end and the lower end of each C-shaped groove 7 are respectively distributed on the upper pad body 1 and the lower pad body 2, the two C-shaped grooves 7 located on the same side of the columnar pad are symmetrically arranged on the left and right sides of the rib hole 4, and the four C-shaped spring clips 3 are respectively clamped in the four C-shaped grooves 7 to realize the fixed connection between the upper pad body 1 and the lower pad body 2.
