Abstract
The utility model discloses a step mounting structure of railway pier hood, including railway pier and step, 5 degrees settings two corrugated metal pipes that are parallel to each other of difference downward sloping in a vertical side of railway pier, corrugated metal pipe's medial extremity is setting up the concrete shutoff piece, the step be character cut in bas-relief, two pins of step insert respectively the corrugated metal pipe in and the corrugated metal pipe intussuseption be provided with the epoxy mortar, the step pin outside portion that is located the railway pier outside bends downwards and constitutes the step horizontal segment. The utility model discloses can avoid welding operation under the high altitude condition and execute and do many first alloy and ooze anticorrosive treatment's step altogether, reduce the step ladder and execute and do the degree of difficulty.
Description
Technical Field
The utility model relates to a ladder mounting structure of railway pier hood, this ladder provide the upper and lower passageway between rail and the hanging flower basket for the maintainer, belong to bridge and culvert engineering technical field.
Background
The way that railway pier provides passageway between rail and the hanging flower basket sets up U-shaped steel bar ladder for pier top cap side, supplies the maintainer to come and go between rail and hanging flower basket, and common way is: and pre-embedding steel bars at the positions, corresponding to the steps, on the side surface of the top cap of the railway pier, and welding the U-shaped steel bar steps on the reserved steel bars. A hole is reserved in a pier top cap template before construction, top cap steel bars are bound, after the templates are connected into a whole, embedded steel bars are inserted into the hole to a certain depth, the pier top cap steel bar cage is fixed, and concrete is poured; and (3) demoulding after the concrete reaches 75% of the design strength, mounting the fence and the hanging basket on the top cap, and finally welding the U-shaped step ladder on the reserved steel bars. The traditional step ladder construction method is complex in process, and mainly comprises the following 4 points: 1. and reserving holes on the template, and pouring pier top cap concrete to increase the process of blocking the holes. 2. The U-shaped ladder is reserved for welding reinforcing steel bars and is inserted into the top cap reinforcing steel bar cage from the hole, and the process of fixing the reserved welding reinforcing steel bars in the reinforcing steel bar cage is added. 3. A U-shaped step ladder is welded on a reserved steel bar, which belongs to high-altitude welding operation and increases the construction difficulty. 4. After the U-shaped step ladder is welded, the multi-element alloy anticorrosion treatment is carried out on the welding seam according to the regulations of the railway industry, and the anticorrosion treatment needs to be carried out at high temperature, so that the difficulty is great.
Disclosure of Invention
An object of the utility model is to provide a step mounting structure of railway pier hood can avoid under the high altitude condition welding operation and execute and do many first alloys and ooze anticorrosive treatment's step altogether, reduces the step and executes and do the degree of difficulty.
The utility model discloses a realize above-mentioned purpose, the technical solution who adopts is: the utility model provides a step ladder mounting structure of railway pier hood, includes railway pier and step ladder, is setting up two corrugated metal pipes that are parallel to each other in a vertical side of railway pier downward sloping 5 respectively, and corrugated metal pipe's medial extremity is setting up the concrete shutoff piece, the step ladder be character cut in bas-relief, two pins of step ladder insert respectively the corrugated metal pipe in and the corrugated metal pipe intussuseption be set up the epoxy mortar, the step ladder pin outside portion that is located the railway pier outside bends downwards and constitutes the step horizontal segment.
In order to prevent the metal corrugated pipe from flowing into the railway pier top cap in the concrete pouring and vibrating process, a concrete plugging block is adopted to plug one end of the metal corrugated pipe extending into the top cap, the concrete plugging block is not taken out, a rubber plugging block is adopted to plug one end of the metal corrugated pipe extending out of the top cap, and the top cap is taken out for recycling after being demoulded; after the top cap concrete is demoulded and initially set, inserting the step ladder into the metal corrugated pipe, and pouring epoxy resin mortar; and curing the epoxy resin mortar under the same condition with the top cap concrete, and normally using the epoxy resin mortar after curing.
The utility model discloses a set up corrugated metal pipe and reserve the pore as the installation of step ladder. Through setting up concrete block and rubber block, guarantee that top cap concrete placement and the use of the follow-up grout of metal bellows are guaranteed not to flow into the metal bellows in the process of vibrating. The pore canal of the arranged metal corrugated pipe is inclined downwards by 5 degrees, which is beneficial to the compact grouting of epoxy resin mortar. Adopt the epoxy resin mortar anchor step that intensity is high, initial set time is short, anchor intensity is high, and anchor time is short, shortens the step construction cycle, buries the section through buckling the step, makes it unanimous with the metal bellows direction, the step location of being convenient for.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a side view of the ladder of the present invention;
FIG. 2 is a perspective view of the ladder;
FIG. 3 is a schematic view of a pier structure before installation of the ladder;
fig. 4 is a schematic view of a pier structure after the ladder is installed.
Detailed Description
The utility model provides a ladder mounting structure of railway pier hood, as shown in fig. 1, 2, 3, 4, including railway pier 6 and ladder 5, the 5 metal bellows 1 that are parallel to each other are being set up to the 5 deg. that inclines down respectively in a vertical side 61 of railway pier, the medial extremity of metal bellows 1 is setting up concrete shutoff piece 3, ladder 5 be character cut in bas-relief, two base pin outside parts of ladder constitute horizontal segment 51, medial part constitute slope section 52, slope section 52 inserts respectively metal bellows 3 in and metal bellows 3 intussuseption be provided with epoxy mortar 2, the ladder 5 base pin outside part that is located the railway pier outside bends downwards and constitutes the ladder horizontal segment that is used for bearing. As shown in figure 3, before the ladder is installed, a rubber plug 4 is arranged in the port of the outer side of the metal corrugated pipe 1, and the rubber plug 4 is taken out when the ladder is installed.
Claims (1)
1. The utility model provides a step ladder mounting structure of railway pier top cap, includes railway pier and step ladder, characterized by: two parallel metal corrugated pipes are arranged in a vertical side face of the railway pier and are respectively inclined downwards by 5 degrees, a concrete plugging block is arranged at the inner side end of each metal corrugated pipe, the step is in a concave shape, two pins of the step are respectively inserted into the metal corrugated pipes, epoxy resin mortar is filled in the metal corrugated pipes, and the outer side parts of the pins of the step, which are positioned outside the railway pier, are bent downwards to form a horizontal section of the step.
