[0023] Embodiment one

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4The shown recycled aggregate concrete cavity floor support device comprises a pry-mounted base 100, a rectangular boss 101 arranged on one side of the pry-mounted base 100, a strip-shaped clamping groove 102 symmetrically arranged in the end faces of the two ends of the rectangular boss 101, a plurality of groups of vertical support blocks 104 symmetrically arranged in the strip-shaped clamping groove 102, a strip-shaped support plate 107 connected with the upper end faces of the vertical support blocks 104 at the two ends respectively, and a plurality of transition support plates 108 evenly arranged on one side of the strip-shaped support plate 107 respectively.

[0025] The working principle is as follows:

[0026] (1) According to the construction specification requirements, the pry-mounted base 100 and the rectangular boss 101 are arranged on the corresponding working surface;

[0027] (2) A plurality of groups of vertical support blocks 104 are clamped in the strip-shaped clamping groove 102, at this time the strip-shaped support plate 107 is horizontally located on the surface of the rectangular boss 101, and the size of the cavity floor is installed, the spacing between the strip-shaped support plates 107 is adjusted, and during the adjustment, only the vertical support blocks 104 need to be horizontally slid in the vertical support blocks 104;

[0028] (3) The bottom surface of the assembled cavity floor A is placed on the surface of the transition support plate 108.

[0029] Example Two

[0030] On the basis of Example One, the recycled aggregate concrete cavity floor support device further comprises a strip-shaped bolt through groove 103 arranged in the outer walls on the two sides of the rectangular boss 101 respectively and matched with the strip-shaped clamping groove 102, a vertical support block screw groove 105 arranged in one side of the vertical support block 104 respectively, and a nut bolt 106 for fixing the rectangular boss 101 and the vertical support block 104 through the strip-shaped bolt through groove 103 and the vertical support block screw groove 105.

[0031] The above design is used for the relative horizontal adjustment between the strip-shaped support plates 107 in (2) of Example One, and the main purpose is to lock and fix the rectangular boss 101 and the vertical support block 104 after relative horizontal adjustment through the strip-shaped bolt through groove 103 and the vertical support block screw groove 105 by using the nut bolt 106, so as to prevent the sliding problem of the cavity floor A placed on the surface of the transition support plate 108, and solve the safety hazard.

[0032] In addition, the vertical support block 104 and the strip-shaped support plate 107 are preferably in an n-shaped structure, which can be conveniently placed vertically in the strip-shaped clamping groove 102 on the two sides of the rectangular boss 101, and is convenient to operate and use.

[0033] In addition, preferably several transition support plates 108 are welded on one side of the strip-shaped support plate 107, and the other side of the strip-shaped support plate 107 abuts against the surface of the rectangular boss 101, which not only can improve the service life of the strip-shaped support plate 107 (reduce the surface wear of the strip-shaped support plate 107), but also can conveniently guide the hoisting rope (the hoisting rope passes through between the transition support plates 108).

[0034] In addition, the connecting surface of the pry-mounted base 100 and the rectangular boss 101 is in a stepped structure and has a certain vertical height, which on the one hand prevents foreign matters from invading the cavity floor A and causing damage to the cavity floor A, and on the other hand solves the pollution problem of the cavity floor A caused by rainwater and meets the high-quality pouring construction of the subsequent hoisted concrete.
