Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-6 , an assembled non-disassembly steel truss floor deck, comprising a galvanized steel plate 1 and two base rods 2 arranged above the galvanized steel plate 1, a balance rod 4 is arranged above the two base rods 2, a connecting rod 3 is fixedly installed between the balance rod 4 and the two base rods 2, and a U-shaped rod 5 is arranged above the galvanized steel plate 1;

[0025] The U-shaped rod 5 is fitted with the two base rods 2. A limiting assembly 8 for further limiting the two base rods 2 is provided on the U-shaped rod 5. A limiting panel 9 is slidably provided on the U-shaped rod 5. Through the setting of the U-shaped rod 5, it can conveniently support the base rod 2 and also facilitate limiting the position thereof. The limiting assembly 8 can drive the limiting panel 9 to slide so as to limit the position of the base rod 2.

[0026] The limiting assembly 8 includes a rotating rod 81 rotatably set on the U-shaped rod 5 and a disc 82 fixedly installed at the lower end of the rotating rod 81, and limiting blocks 83 are fixedly installed at both ends of the disc 82. A circular groove 6 is opened on the galvanized steel plate 1, and limiting holes 7 are opened at both ends of the circular groove 6. The disc 82 and the limiting block 83 are inserted into the corresponding circular groove 6 and the limiting hole 7.

[0027] A limiting block 12 and a limiting unit 11 are fixedly installed on the bottom wall of the inner cavity of the circular groove 6. The limiting unit 11 includes a mounting groove 112 connected to the circular groove 6 and a trapezoidal block 111 slidably arranged on the mounting groove 112. A spring 113 is fixedly connected between the trapezoidal block 111 and the mounting groove 112. The trapezoidal block 111 is arranged on one side of the limit block 83.

[0028] In this embodiment: first, the overall base rod 2, connecting rod 3, balance rod 4 and U-shaped rod 5 are placed on the galvanized steel plate 1. During the placement process, the limit block 83 and the disc 82 are inserted into the corresponding circular groove 6 and the limit hole 7. After being placed in, the U-shaped rod 5 is just in contact with the galvanized steel plate 1. At this time, the rotating rod 81 is rotated, and the rotating rod 81 drives the limit block 83 and the disc 82 to rotate along the circular groove 6 until they conflict with the limit block 83 and the trapezoidal block 111. The trapezoidal block 111 will slide along the installation groove 112 and squeeze the spring 113 at the same time. When the limit block 83 is separated from the trapezoidal block 111, the trapezoidal block 111 is subjected to the elastic force of the spring 113, which can limit the limit block 83, and the steel truss floor decking can be conveniently assembled without the need for formwork and steel bar tying. The operation is simple and convenient to use.

[0029] Embodiment 2

[0030] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-3 The limiting assembly 8 also includes a connecting hole 84 opened on the U-shaped rod 5 and a movable groove 87 connected to the side wall of the inner cavity of the U-shaped rod 5. A sliding rod 88 is fixedly installed on the side wall of the movable groove 87. A mounting rod 89 is slidably arranged on the sliding rod 88. An extrusion block 85 is fixedly installed on the upper end of the mounting rod 89. A connecting rope 86 is fixedly installed on one end of the extrusion block 85. The connecting rope 86 is wound around the rotating rod 81. The extrusion block 85 is arranged above the limiting panel 9.

[0031] The joints between the upper end surface of the extrusion block 85 and the lower end surface of the limiting panel 9 are both arranged in an inclined surface to facilitate displacement of the two.

[0032] A plurality of pulleys 10 are fixedly mounted on the inner cavity side wall of the U-shaped rod 5, and the plurality of pulleys 10 are all in contact with the connecting rope 86. By setting the pulleys 10, the friction of the connecting rope 86 can be reduced and its service life can be extended.

[0033] In this embodiment, when the rotating rod 81 rotates, it will pull the two connecting ropes 86. At this time, the connecting ropes 86 will pull the extrusion block 85. The extrusion block 85 slides along the sliding rod 88 through the mounting rod 89. When the extrusion block 85 slides, it will squeeze the limiting panel 9 at the corresponding position. After being squeezed, the limiting panel 9 will slide along the connecting hole 84 until the limiting panel 9 contacts the base rod 2, thereby ensuring the limitation of the position of the base rod 2 and better stabilizing the base rod 2 to maintain stability.
