The width of the first slot 311 is matched with the thickness of the first board 100, and the width of the second slot 312 is matched with the thickness of the second board 200.

Optionally, the width of the first slot 311 is equal to the width of the second slot 312, and correspondingly, the thickness of the first board 100 is equal to the thickness of the second board 200. In some embodiments, the first plate 100 and the second plate 200 may be identical in structure, so as to improve the replaceability of the expansion joint isolation device.

More specifically, as shown in fig. 4, the first plate 100 includes a first body 110 and a first connecting portion 120 connected along a length direction thereof, and the second plate 200 includes a second body 210 and a second connecting portion 220 connected along a length direction thereof; the two faces of deviating from each other of the first connecting portion 120 and the second connecting portion 220 are both provided with two concave surfaces, and the two concave surfaces of the first connecting portion 120 and the second connecting portion 220 which are arranged opposite to each other can be abutted against the groove walls of the first clamping groove 311 and the second clamping groove 312 respectively.

The two concave surfaces of the first connecting portion 120 and the second connecting portion 220, which are disposed opposite to each other, can position the fastener 310, so as to facilitate the installation of the fastener 310. With the above description of the fastener 310, the fastener 310 of this structure can not only connect the first panel 100 and the second panel 200, but also position the fastener 310 to facilitate the installation of the fastener 310.

Illustratively, the cross-sectional shapes of the first and second pull holes 130 and 230 may be circular or rectangular.

In this embodiment, the first plate body 100 and the second plate body 200 are both made of steel plates; since the steel plate has a certain rigidity, this arrangement can reduce the possibility of vibration deformation of the first plate body 100 and the second plate body 200 to some extent.

One implementation manner of this embodiment is: the thicknesses of the first plate body 100 and the second plate body 200 are both 5mm, wherein the part of the cushion block 320 between the first plate body 100 and the second plate body 200 is 1 cm; the first plate body 100 and the second plate body 200 are both provided with grooves of 2cm × 2mm at positions 20cm away from the bottom surface, and an expansion joint of about 2cm can be constructed through the arrangement.

An operation method of the expansion joint isolation device comprises the following steps:

mounting a cushion block 320 in a groove between the first board 100 and the second board 200, and then connecting the first board 100 and the second board 200 together by a fastener 310 to form an assembled expansion joint isolation device, and placing the assembled expansion joint isolation device at a required position;

after the pouring is completed, the fastener 310 is removed, the cushion block 320 is pulled out from one side, and finally the first board 100 and the second board 200 are removed.

More than synthesizing, this expansion joint isolating device can guarantee first plate body 100 and second plate body 200 can not take place to vibrate the deformation well, consequently the expansion joint that constructs through this expansion joint isolating device is difficult to deform outward, can form a straight logical seam, and the shaping effect is better. In addition, the expansion joint isolating device also has the advantages of convenient installation and disassembly, repeated utilization for many times, recycling and the like. In addition, the expansion joint isolation device has a wide application range and can be used in expansion joint construction projects such as side walls and partition walls without waterproof requirements.

This embodiment still provides a concrete side wall, and this concrete side wall constructs through aforementioned expansion joint isolating device.
