Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined or explained in subsequent figures.
Example 1
As further described below with reference to the specific embodiments, referring to fig. 1 to 4, this embodiment 1 is a reinforcing mesh spacer for tunnel concrete casting, including a spacer body 1, the spacer body 1 is provided with a first engaging groove 2 for engaging with a reinforcing mesh, one end of the spacer body 1 is embedded with a ball 5 and rotatably connected therewith, specifically, before the reinforcing mesh is laid into a gap between a steel plate and a tunnel wall, a worker previously inserts a plurality of spacer bodies 1 into the reinforcing mesh through the first engaging groove 2, and winds a fixing wire around the tail end of the spacer body 1 to fix the spacer bodies on the reinforcing mesh, the reinforcing mesh slides in from one side of the steel plate, the ball 5 of the spacer body 1 contacts and rolls with a supporting steel plate, and changes from surface contact to point contact, so that resistance during the laying of the reinforcing mesh is greatly reduced, thereby greatly reducing the possibility of engagement, and making the operation more convenient and easier, and simultaneously ensuring that any point of the reinforcing mesh and the surface of the steel plate has an equal interval, and further casting concrete into the gap between the tunnel wall and the steel plate to complete construction, thereby solving the problem of exposed reinforcing mesh.
In this embodiment, the second slot 3 for inserting the reinforcing mesh is further formed at one end of the cushion block body 1, the second slot 3 and the first slot 2 are vertically crossed, and the bottom of the first slot 2 and the bottom of the second slot 3 have a spacing distance in the axial direction of the cushion block body 1, specifically, the reinforcing mesh is formed by weaving and interlacing the reinforcing mesh in a vertically and horizontally staggered manner, the first slot 2 and the second slot 3 are vertically crossed and the spacing distance is used for perfectly adapting to the interlaced position of the reinforcing mesh, the fixing method is firmer, and relative sliding between the cushion block body 1 and the reinforcing mesh is not easy to occur.
In this embodiment, the bottoms of the first engaging groove 2 and the second engaging groove 3 are both arc-shaped structures, specifically, the steel bars on the steel bar mesh are mostly cylindrical steel bars, and the first engaging groove 2 and the second engaging groove 3 of the arc-shaped structures make the connection between the cushion block body 1 and the steel bar mesh more tight.
