Description

Novel replaceable channel groove making mold

Technical Field

The utility model relates to the technical field of the track, especially, relate to a novel groove mould is made to removable channel.

Background

Channel embedment, which uses T-bolts or toothed bolts with mating nuts and washers, can be used to secure any structural component, and is an ideal fixture for ease of installation and adjustability. The channel is pre-buried in the concrete, and the surface is parallel and level with the concrete. In urban rail transit tunnels and electrified railway contact net tunnels, pre-buried channels are required to serve as fixing devices of contact nets, and the expansion bolts are used as substitutes of the conventional expansion bolts, so that the expansion bolts are remarkably improved.

However, after the existing embedded channel is embedded in the concrete, the embedded sleeve is axially inserted into the concrete, so that the embedded sleeve is not easy to disassemble, and the adjustment and maintenance are difficult. Some replaceable channels are exposed outside cement, the transverse shearing resistance of the replaceable channels can be greatly influenced due to no protection of a cement groove, the fire resistance can not meet the requirement, and some replaceable channels are pre-embedded with an iron plate and then fixed on the iron plate, or are pre-embedded with a section of channel steel and then installed inside; these methods are complicated and costly to operate.

Therefore, a novel replaceable channel grooving die is provided to solve the problem.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel groove mould is done to removable channel, includes the mould body and pre-buried sleeve, its characterized in that, mould body up end equipartition has the inside round hole of a plurality of intercommunications, the internal equipartition of mould has a plurality of die sleeve, and is a plurality of the die sleeve corresponds, and is a plurality of with a plurality of round hole positions respectively the die sleeve upper end all welds with the mould body, be equipped with the working of plastics in the round hole, the first half of working of plastics extends to outside the round hole and with pre-buried sleeve threaded connection, the latter half of working of plastics extends to the mould internally and with die sleeve threaded connection.

Preferably, the embedded sleeve is made of stainless steel, and the surface of the die body is covered with a zinc coating.

Preferably, plugs are welded at two ports of the mold body, the side faces of the plugs are trapezoidal, the plugs are inserted into the ports of the mold body, and the plugs and the mold body are made of Q345B materials.

Preferably, the upper half part and the lower half part of the plastic part are integrated, and a ring groove for breaking is arranged at the joint of the upper half part and the lower half part.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the pre-embedded sleeve in the grooving die and the die body are of a detachable connection structure, and the pre-embedded sleeve is made of stainless steel materials and can be pre-embedded in concrete for a long time; when pre-buried, with the embedded sleeve and the mould body is pre-buried in cement, terminal surface and cement surface are kept flat under the mould body simultaneously, and the cement is dismantled the mould body after the setting futilely and gets off at cement surface formation mounting groove, and the embedded sleeve is pre-buried in cement simultaneously, can install the channel in the mounting groove through the screw hole groove of a plurality of embedded sleeve lower extremes, and the mould body cross-section is the trapezium, and the mould body can not destroy cement groove face at the in-process of loading and unloading, conveniently dismantles.

2. The fixed pre-buried sleeve position of the mould body and working of plastics, it is pre-buried to have realized pre-buried sleeve's accurate position, after having the mounting groove, the mountable channel, the channel damage back, can also change again, the end cap of the mould body tip is the end cap that has the inclination, the end cap is as an organic whole with the welding of the mould body, convenient to detach like this, do not destroy cement groove surface simultaneously, the even pre-buried of pre-buried sleeve can be according to the demand in the mounting groove different position installation channels in cement in addition.

3. When the channel is arranged in the installation groove made of the groove making mold, compared with the existing channel exposed outside cement, the channel can be protected by the cement, and the transverse shear resistance is larger; the current pre-buried channel in cement of contrast, the change is conveniently dismantled, can decide the position and the length of installation channel moreover according to the demand.

Drawings

Fig. 1 is a schematic structural view of a grooving mold of a novel replaceable channel grooving mold provided by the present invention;

fig. 2 is the utility model provides a novel removable channel is made groove mould and is looked sideways make groove mould structure schematic diagram.

In the figure: the mould comprises a mould body 1, a pre-buried sleeve 2, a mould sleeve 3, a plastic part 4, an upper half part 5, a lower half part 6 and a plug 7.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a novel groove mould is made to removable channel, including the mould body 1 and pre-buried sleeve 2, pre-buried sleeve 2 adopts stainless steel, the surface covering of the mould body 1 has the galvanizing coat, the durability has, reduce the corrosion, increase of service life, the welding of the both ends mouth department of the mould body 1 has end cap 7, the side of end cap 7 is trapezoidal, and end cap 7 pegs graft in the port of the mould body 1, end cap 7 all adopts Q345B material with the mould body 1, do not destroy the cement tank surface when convenient to detach like this, can allow the tolerance within 2-3MM in length when installing new channel, reduce and make installation cost.
