Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, with reference to the accompanying drawing and specific embodiment pair
The present invention is described in further detail.
As shown in Figure 1 and Figure 2, the fixed device of a kind of four side spacer bar concrete slab blast wave load tests, the examination
Test the reinforced concrete plinth 5 that fixed device has hollow structure；The reinforced concrete plinth 5 is the square of upper surface opening
Body, and the middle part of the side wall surface of reinforced concrete plinth 5 have opened with what the hollow structure of reinforced concrete plinth was connected to
Mouthful；The upper surface of the reinforced concrete plinth 5 has the rectangle card slot of collar reinforced concrete plinth upper surface opening setting
6；In conjunction with Fig. 3, the test fixtures are additionally provided with armoured concrete slab, and the armoured concrete slab 4 is plate, institute
The surrounding for stating plate lower end surface is bent to form the rectangular frame of upper surface sealing, lower end surface opening, and rectangle frame downward vertically
