Abstract
The utility model discloses a pressing part system used for an immersed tube channel GINA water-stop. The pressing part system is welded to a steel shell and characterized by being mainly composed of pressing blocks and pressing plates, wherein the pressing blocks and the pressing plates are arranged coaxially. The pressing plates are located above the pressing blocks which are provided with screw holes. Each pressing plate is composed of a concave-type through hole and a limiting plate, wherein the limiting plate extends outwards from one side of the corresponding concave-type through hole. The concave-type through holes are connected with the screw holes through bolts in a fastened mode. The pressing part system has the advantages that in the butt joint process of a front tube joint and a rear tube joint, the water-stop is pressed flat and extruded toward the two sides of the pressing part system, and the pressing part system is used for clamping the two wing edges of the GINA water-stop installed in place through the pressing blocks and the pressing plates, so that the pressing part system plays a role in fixing the water-stop in an in-place mode, and it is avoided that because screws of the pressing part system are excessively protruded out of the surfaces of the pressing parts, the GINA water-stop is damaged; the pressing part system can be adaptive to certain screw hole machining deviation, and pre-tightening on the screws is not affected.
Description
Technical field
The utility model relates to waterstop fastening devices, is specifically related to a kind of casting die system for immersed tube tunnel GINA waterstop.
Background technology
In immersed tube tunnel, the joint waterproofing between pipeline section and pipeline section is very important, often adopts GINA, two kinds of sealings of OMEGA to bring the tunnel joint waterproof task of bearing.
The material of GINA waterstop is generally natural rubber or butadiene-styrene rubber, after tube manufacture, GINA waterstop is installed on the end box hat of pipeline section termination, then along with the haul of pipeline section, sinking, to assigned address, through contraposition, drawing, crimping process, acts on the free-ended huge hydraulic pressure of new sinking pipeline section, by GINA waterstop tightly densification in the end box hat surface of a upper joint sinking pipeline section, played the good result of sealing waterproof.
In addition, the fixed form that GINA waterstop adopts is also more important problem, the GINA waterstop of general immersed tube joint adopts perforation fixed form, especially see many earthquakes countries such as Japan, perforation fixed form is in GINA waterstop manufacturing process, in its two side flange reserved screw that keeps at a certain distance away, in the time that waterstop is installed, pressing plate is pressed on waterstop flange, and bolt, through pressing plate, flange, is finally fixed on end box hat.Its advantage is waterstop fixation, can not come off; When its shortcoming is to install, screw aligning accuracy is had relatively high expectations, construction inconvenience, and need hold perforate on box hat, reduce the integral waterproofing performance of end box hat.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of casting die system for immersed tube tunnel GINA waterstop is provided, this casting die system is welded on end box hat, block the both wings of the GINA waterstop being in place by briquetting and pressing plate, thereby play its effect in position.
The utility model object realizes and being completed by following technical scheme:
A kind of casting die system for immersed tube tunnel GINA waterstop, this casting die system is welded on end box hat, it is characterized in that described casting die system is mainly made up of the briquetting coaxially arranging, pressing plate, described pressing plate is positioned at described briquetting top, described briquetting has screw, the limiting plate that described pressing plate is stretched by matrix through hole and from described matrix through hole one epitaxial lateral overgrowth forms, and described matrix through hole is connected by screw fastening with described screw.
The height of described briquetting is lower than the height on described GINA waterstop two edges of a wing.
The diameter of described matrix through hole is greater than described screw head diameter.
Described matrix through hole is provided with spring washer on bottom surface.
The utility model has the advantages that, in the tube coupling docking operation of front and back, waterstop is crushed and pushes to the casting die system of both sides, casting die system is blocked two edges of a wing of the GINA waterstop being in place by briquetting and pressing plate, thereby play to its effect in position the injury of having avoided the too outstanding laminate surface of screw of casting die system to cause GINA waterstop; And can adapt to certain screw machining deviation, the pretension of screw is not affected.
Brief description of the drawings
Fig. 1 is the scheme of installation of casting die system in the utility model;
Fig. 2 is the partial enlarged drawing I of Fig. 1 in the utility model;
Fig. 3 is the utility model center platen schematic diagram.
Detailed description of the invention
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Fig. 1-3, in figure, mark 1-9 is respectively: GINA waterstop 1, screw 2, pressing plate 3, briquetting 4, end box hat 5, matrix through hole 6, spring washer 7, limiting plate 8, the edge of a wing 9.
Embodiment: as shown in Figure 1, the present embodiment is specifically related to a kind of casting die system for immersed tube tunnel GINA waterstop, this casting die system adopts the briquetting 4 and the pressing plate 3 that are welded on end box hat 5, blocks the edge of a wing of GINA waterstop 1 both sides that are in place, thereby plays its effect in position.
As shown in Figure 1, 2, 3, casting die system mainly comprises briquetting 4, pressing plate 3 and screw 2.
Between two side bottoms of briquetting 4 and end box hat 5, be welded and fixed, heart position offers the female screw of tool therein, the size of the size of this screw and screw 2 matches, in addition the height of briquetting 4 is less than the thickness of two side wing edges 9 of GINA waterstop 1, to give the contact surface of pressing plate 3 reserved lateral Displacements.
Pressing plate 3 is positioned at the top of briquetting 4, as shown in Figure 2,3, pressing plate 3 is designed to concave configuration, specifically formed by matrix through hole 6 and limiting plate 8, limiting plate 8 is from the outside horizontal expansion in the side of matrix through hole 6, and both are structure as a whole, that is to say, the side direction outside wall surface of matrix through hole 6 provides side direction to prop up a grade power to the edge of a wing 9, and the Ze Xiang edge of a wing, bottom surface 9 of limiting plate 8 provides the spacing of vertical direction, certainly, the length of limiting plate 8 should be less than the width on the edge of a wing 9, in order to avoid limiting plate 8 causes damage to GINA waterstop 1.
The concrete hexagon socket cap head screw that adopts of screw 2, it tightens cooperation by running through matrix through hole 6 with the screw of briquetting 4, so that fixing between briquetting 4 and pressing plate 3, loosening for preventing that screw 2 from producing, between the bottom surface of matrix through hole 6 and the socket cap of screw 2, a spring washer 7 is set.The area of the matrix through hole 6 of pressing plate 3 is greater than the head area of screw 2, can make screw 2 and the screw of briquetting 4 exist in the situation of certain deviations, still can tighten screw 2.
In the present embodiment, the advantage of casting die system is GINA waterstop itself not to be produced and destroyed, and it is convenient to install, and is conducive to improve work actual effect; And can adapt to certain casting die screw machining deviation, the pretension of screw is not affected.
