Problems solved by technology

[0002] The tongue-and-groove plate is a metal plate commonly used in construction. Specifically, it is an important part of the steel mold for the production of prestressed pipe piles. It is responsible for the mold opening of the pipe mold and the sealing of the tongue and groove of the mold. However, there is a slight negligence when assembling the upper table There will be gaps, and it will be uneven, which will affect the sealing of the mold, and produce centrifugal slurry leakage and other phenomena.
The JC / T605-2005 standard stipulates that "at the joint, the gap between the tongue and groove plate and the cylinder is generally on the segmented mold body, the length of a single segment should not be greater than 50mm, and the cumulative length should not be greater than the length of the segmented mold body." 1 / 20 of that, no gap of 1mm is allowed", and in actual operation, if you don't pay attention, the gap will be larger than the standard. arc, and then use arc welding to weld the gap, because it is a welded part, it is labor-intensive and time-consuming to repair

Embodiment 1

[0013] Depend on figure 2 Known, a kind of circular mold tongue-and-groove plate, comprises cylinder body plate 1 and tongue-and-groove plate 2, described tongue-and-groove plate 2 is made up of upper and lower two templates, and boss is arranged on the template, and groove is arranged on the lower template, And fixed with positioning pins, the cylinder plate 1 is annular. It is divided into upper and lower parts. The upper and lower ends of one side of the tongue-and-groove plate 2 are respectively provided with arc grooves 2-1. The width of the arc groove 2-1 is the same as the thickness of the annular cylinder plate 1. The cylinder The outer diameter of the plate 1 is matched with the arc groove 2-1 of the tongue and groove plate 2 and then welded.

Embodiment 2

[0015] Depend on image 3 Known, a kind of square mold tongue-and-groove plate, comprises cylinder body plate 1 and tongue-and-groove plate 2, and described tongue-and-groove plate 2 is made up of upper and lower two templates, and boss is arranged on the template, and groove is arranged on the lower template, The upper and lower templates are fixed with positioning pins, and one side of the tongue and groove plate 2 is provided with an arc groove 2-1, the radius of the arc is R23mm, and the radian of the arc groove 2-1 is the same as that of the annular cylinder plate 1. The inner diameter is tangent at 90o, and the cylinder plate 1 is set on the tangent line of the arc groove 2-1, and then welded with the tongue and groove plate 2.

[0016] Compared with the original tongue-and-groove plate, the present invention has zero gap in the pipe mold and improves the mold-closing standard.

Abstract

A tubular pile steel die matchboard comprises a cylinder board (1) and a matchboard body (2). The matchboard body is formed by an upper die plate and a lower die plate. A boss is arranged on the upper die plate, a groove is formed in the lower die plate, the lower die plate is fixed through a locating pin and the cylinder board (1) is annular. The tubular pile steel die matchboard is characterized in that arc grooves (2-1) are formed in the upper end of one side of the matchboard body (2) and the lower end of the matchboard body (2)respectively, the width of the arc grooves (2-1) is the same as the thickness of the annular cylinder board (1), and the cylinder board (1) is welded with the matchboard body (2) after the diameter part of the cylinder board (1) is matched with the arc grooves (2-1). According to the tubular pile steel die matchboard, the cylinder board and the matchboard body are welded after being assembled, and a pipe die is free of clearance, so that the sealing performance of a die opening rabbet and the sealing performance of a die assembly rabbet are higher than the requirements of national standards, and the phenomena such as centrifugal pulp leakage cannot occur.
