SU727730A1 - Apparatus for filling-up expansion joints in prefabricated linings - Google Patents

Description

The invention relates to the construction of prefabricated coatings, namely, devices for sealing joints between elements in the lining of irrigation canals, road and airfield pavements.

A device for filling an elastic gasket in a freshly laid concrete pavement is known, including a working body mounted on the base machine frame, made in the form of disks arranged at an angle to one another and attached to the frame by means of levers in the vertical plane, and on each lever a vibrator is mounted l

It is also known a device for creating a butt joint, including a movable frame and a bunker with a discharge part mounted thereon and a working body for laying the elastic element 2.

A disadvantage of the known devices is that they can only work in conjunction with concrete pavers, and pulling an elastic element through the working member requires considerable traction force, which makes them difficult to apply in cramped conditions due to the difficulty of orienting the elastic element along the seam, and by dragging the element it may be damaged,

The purpose of the invention is to reduce the energy consumption for movement and accelerate the laying of an elastic element.

This goal is achieved by the fact that

According to the proposed device, which includes a movable frame, a bunker with a unloading part and a working member for laying the elastic element mounted on it, the unloading part of the bunker is made with two nozzles arranged stepwise in the course of the movement, the working member for placing the elastic element in the first one.

body 6 for laying the elastic polymer element 7, including the casing 8, directed to the rollers 9 mounted on the roller 10, and supporting rollers 11 mounted on separate rigidly attached to the hopper 1 axis x 12, sealing the working body 13 with the smoothing plate 14 and a vibrator 15, which is powered from the receiver 16 through pipe 17 when the two-way valve 18 is opened. The hopper 1 is connected to the frame 2 by means of the half-axis 20 with the help of the sleeve 19, which makes it possible to change its angle of inclination relative to the frame 2. Bracket 21 The carcass 22 for the coil of the elastic element 7 is fitted on the hopper 1. On the movable frame 2 is mounted the seat 23 for the operator. The stepped nozzles 24 and 23 with flaps 26 and 27 of the segment type are made on the discharge part of the bunker 1, of which in the first part

movement is the working body 6,

The principle of the machine is as follows. The concrete mix put into the expansion joint is loaded into the hopper 1, a coil with an elastic element 7 is installed on the coil 22, the receiver 16 is filled with compressed air, the operator takes His work place on the seat 23, the device goes down to the bottom of the keel and orients along the deformation woo .

From the reel 22, the elastic element 7 is unwound, is passed through the guides 9 and the supporting rollers 11 of the working body 6 and passes to the slab. The operator opens the valve 18 and turns on the vibrator 15 compacted with his working body 13, then opens the flaps 26, 27 on the nozzles 24, 25 of the bunker 1 and, including the troso-block system 5, starts moving the device. The concrete mixture 28 of the first (longer) nozzle 26 stops at the bottom of the seam, due to the heavy force generated by the movement of the device, the elastic element 7 is unwound from the reel 22 and placed in a strictly defined position relative to the walls of the seam into the concrete mix that filled the seam , J and the second nozzle 27 provides a mixture that covers the elastic polymer element 7 from above and fills the seam. In order to reduce the pulling force required for laying the elastic element into the seam, it is fed into mutually perpendicular strings of movable profile rollers 9, 11. The smoothing plate 14 and the pneumatic vibrator 15 level and compact the concrete mix. Due to the free suspension of the hopper 1.in semi-axis x 20 on

Moving the pc1me 2 when the device is moving and the work of the compacting ofiraHa 13 is working, hopper 1 oscillates, which ensures uniform

0 feeding and laying of concrete mix.

This embodiment of the device provides improved performance when sealing expansion joints and reducing the cost of these works on

5 35-40%.
