[0012] The beneficial effects of this improvement are: the roughened pad can increase the friction between the web and the bottom plate, thereby making the web's constraint on the position of the lower chord more reliable and secure.
[0013] To ensure a secure fixation effect:
[0014] As a further improvement to the above technical solution: the rubber gasket is fixed to the web plate by adhesive.
[0015] The beneficial effects of this improvement are: the use of rubber pads can absorb some of the vibration and increase the friction between the web and the lower chord, making the fixation of the web to the lower chord more reliable and secure.
[0016] To ensure the pressure plate is fixed to the upper chord:
[0017] As a further improvement to the above technical solution: the pressure plate and the web plate are arranged in parallel to each other.
[0018] The beneficial effect of this improvement is that the parallel arrangement of the pressure plates allows for a reliable and secure fixation of the upper chord.
[0019] To ensure the web plate limits the movement of the lower and upper chords:
[0020] As a further improvement to the above technical solution: the web plate and the bottom plate are arranged in parallel to each other.
[0021] The beneficial effect of this improvement is that the parallel arrangement of the web plates makes the position of the lower and upper chords more reliable and secure.
[0022] To facilitate the fixing of the pressure plate to the upper chord:
[0023] As a further improvement to the above technical solution: two bolt rods are symmetrically arranged about the top of the web plate.
[0024] As a further improvement to the above technical solution: after the bolt rod passes through the pressure plate, the pressure plate is fixed with a fixing nut.
[0025] The beneficial effects of this improvement are as follows: by using bolts to pass through the pressure plate and then screwing in the fixing nut to fix the upper chord, the two bolts can work together with the fixing nut to firmly install the pressure plate above the web plate, thereby firmly fixing the upper chord.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0033] like Figure 1-5As shown, a steel truss floor deck includes a base plate 1. A threaded rod 13 is provided above the base plate 1, and the threaded rod 13 passes through a pad 21 and a web plate 2 and is fixed with a nut. A rubber gasket 22 is installed below the web plate 2, and a lower chord 11 is installed below the web plate 2. An upper chord 12 is supported at the top of the web plate 2. A bolt rod 23 is integrally formed above the web plate 2, and a pressure plate 3 is inserted and installed above the bolt rod 23. A fixing nut 24 is threadedly connected to the top of the bolt rod 23. The web plate 2 and the pad 21 are inserted into the threaded rod 13. The lower chord 11 is positioned below the web 2, and the web 2 is fixed to the base plate 1 using nuts. The upper chord 12 is placed on top of the web 2, and the upper chord 12 is fixed by screwing in the fixing nut 24 after the bolt 23 passes through the pressure plate 3. This assembly method ensures the position of the lower chord 11, upper chord 12, and web 2 because the shape of the web 2 is fixed and can be mass-produced, reducing errors during construction and thus ensuring the load-bearing capacity of the device. The cross-section of the web 2 is an isosceles triangle, which makes the support of the web 2 for the device more reliable. The pad... The bottom of plate 21 is roughened. This roughened surface increases the friction between the web plate 2 and the bottom plate 1, thus making the web plate 2 more reliably and firmly fix the position of the lower chord 11. The rubber gasket 22 is glued to the web plate 2. The rubber gasket 22 can absorb some vibration and increase the friction between the web plate 2 and the lower chord 11, making the fixation of the web plate 2 to the lower chord 11 more reliable and secure. The pressure plate 3 is parallel to the web plate 2. This parallel arrangement ensures that the pressure plate 3 reliably and securely fixes the upper chord 12. The web plate 2 and the bottom plate 1 are arranged parallel to each other. This parallel arrangement makes the web plate 2 more reliable and secure in defining the positions of the lower chord 11 and the upper chord 12. Two bolt rods 23 are symmetrically arranged about the top of the web plate 2. The bolt rods 23 pass through the pressure plate 3 and are fixed with the fixing nut 24. The upper chord 12 is fixed by screwing the bolt rods 23 through the pressure plate 3 and into the fixing nut 24. The two bolt rods 23, together with the fixing nut 24, can firmly install the pressure plate 3 above the web plate 2, thereby firmly fixing the upper chord 12.
[0034] The working principle of this utility model is as follows: When using this device, the threaded rod 13 is fixed above the base plate 1 according to the reference. The lower chord rod 11 is laid flat above the base plate 1 in sequence. The web plate 2 and the pad plate 21 are inserted into the threaded rod 13 and the lower chord rod 11 is placed below the web plate 2. The web plate 2 is fixed to the base plate 1 with a nut. The upper chord rod 12 is placed on top of the web plate 2. The bolt rod 23 is inserted through the pressure plate 3 and then screwed into the fixing nut 24 to fix the upper chord rod 12. The assembly of the device is completed in this way. Because the shape of the web plate 2 is fixed, this assembly method ensures the position of the lower chord rod 11, the upper chord rod 12 and the web plate 2, reduces the error generated during construction, and thus ensures the load-bearing capacity of the device.
