When sound passes through the heat-insulating and sound-insulating layer and then weakens medium-high frequency sound, and when the sound enters the cavity again, the sound waves cause air vibration in the cavity, so that most sound energy is converted into heat energy to be consumed, and a better silencing effect is achieved. The cavity is a hole groove formed in the upper surface of the bottom plate, so that sound waves are subjected to multiple diffuse reflection on the wall of the hole groove of the bottom plate, multiple conversion and consumption of sound energy are realized, and the silencing effect is further enhanced.

In order to facilitate the manufacture of the truss in the scheme, two ends of the connecting piece 12 are respectively welded on the upper chord steel bar 10 and the lower chord steel bar 11, the length direction of the truss is located at the tail end of the connecting piece 12, and the connecting steel bar 13 perpendicular to the upper chord steel bar 10 and the lower chord steel bar 11 is welded. The upper chord steel bar 10 and the lower chord steel bar 11 in the truss adopt common anti-seismic screw steel in the market, and the connecting piece 12 is made of steel materials. According to the stress conditions of the upper chord steel bar 10, the lower chord steel bar 11 and the connecting piece 12 in the using process, the diameter of the connecting piece 12 is smaller than the diameters of the upper chord steel bar 10 and the lower chord steel bar 11, and the diameter of the lower chord steel bar 11 is smaller than the diameter of the upper chord steel bar 10.

Example 2
The difference between this embodiment and embodiment 1 is that, as shown in fig. 2, in this embodiment, the first connecting member 121 and the second connecting member 122 are arranged in a "eight" shape, the spacing distance between adjacent connecting members 12 and the shortest spacing distance between the first connecting member 121 and the second connecting member 122 are 10-50cm, and in this embodiment, the spacing distance between adjacent connecting members 12 and the shortest spacing distance between the first connecting member 121 and the second connecting member 122 are equal.
By adopting the splayed connecting pieces 12, a certain distance exists between the first connecting piece 121 and the second connecting piece 122, so that the number of the connecting pieces 12 used by the truss is reduced, and the number of steel bars used by the whole truss is reduced.
Example 3
The present embodiment is different from embodiment 1 in that side connection stages 22 are provided at both sides of the lower end surface of the floor deck 20 as shown in fig. 3.
The arrangement of the side connecting table 22 is convenient for supporting the splicing part after the templates 20 are spliced with each other when the floor support plate 20 is used in the embodiment, so that the floor support plate 20 is fixed in the embodiment.
Example 4
The present embodiment is different from embodiment 3 in that, as shown in fig. 4, the formwork 20 in the present embodiment includes a top plate 30, a heat insulating and sound insulating layer 31, and a bottom plate 32 in sequence from top to bottom, and the lower portion of the truss is located in the top plate 30. In this embodiment, the thermal insulation and sound insulation layer 31 is made of porous open-cell material, that is, the porous open-cell material has a large number of micro gaps and pores which are communicated with each other inside and outside, and the thermal insulation and sound insulation layer 31 is made of rock wool in this embodiment. A concave-convex cavity is formed between the bottom plate 32 and the heat preservation and sound insulation layer 31, specifically, a hole groove can be arranged on the upper surface of the bottom plate 32, a hole groove can also be arranged on the lower surface of the heat preservation and sound insulation layer 31, and hole grooves can also be arranged on the upper surface of the bottom plate 32 and the lower surface of the heat preservation and sound insulation layer 31 simultaneously. The shape of the pore groove can be wave-shaped, zigzag, honeycomb-shaped, pulse-shaped or other irregular shapes and the like. Shock-absorbing pads are paved in the top plate 30 or between the top plate 30 and the heat-preservation sound-insulation layer 31, and also can be paved in the top plate 30 and between the top plate 30 and the heat-preservation sound-insulation layer 31, and the shock-absorbing pads can be made of materials which can play a role of buffering and shock-absorbing, such as pearl cotton, bubble films and the like. The bottom plate 32 is laid with a bottom plate rigid net 33, in this embodiment, the bottom plate rigid net 33 is made of rigid materials such as steel wires, steel bars, iron wires, and the like, and is formed by welding the same kind of materials or different kinds of materials in a criss-cross manner. In this embodiment, the rigid net 33 of the bottom plate is formed by a plurality of transverse steel bars and a plurality of longitudinal steel bars which are staggered to form a net structure.
Since the sound is transmitted by the impact or vibration generated from the floor between the upper and lower floors, the form 20 in this embodiment attenuates the transmission of the sound by taking measures. Namely, when the impact vibration is transmitted to the shock pad on the top plate 30, the vibration force is buffered and weakened on the shock pad, so that the high-frequency sound wave generated by the vibration is simultaneously weakened, the weakened sound wave enters the heat insulation and sound insulation layer 31 of the porous open-cell material, enters the material along the holes communicated with the inside and the outside of the porous open-cell material to cause the vibration of the air in the holes, and most sound energy is converted into heat energy to be consumed due to the viscous resistance, the heat conduction and other effects of the air, so that most medium-frequency and high-frequency sound waves in the sound wave are further eliminated. Finally, when sound waves pass through the heat-insulation sound-insulation layer 31 and enter the hole grooves in the bottom plate 32, the sound waves form multiple diffuse reflection on the uneven hole groove walls, so that sound energy of medium and low frequencies is converted and consumed, and the sound-attenuation and sound-insulation effects are better played.

The reinforcing member 34 extending out of the top plate 30 is convenient for construction on one hand, and after the floor slab is constructed on the other hand, the reinforcing member 34 penetrates through the formwork 20 and the floor slab, so that the hoisting of the formwork 20 is not easy to crack; furthermore, the bent portions of the reinforcing members 34 facilitate the binding of reinforcing bars during the construction of the floor.
Example 7
The present embodiment is different from embodiment 5 in that, as shown in fig. 9, the bent portion of the reinforcing member 34 is disposed perpendicular to the reinforcing member 34 in the present embodiment.
Example 8
The difference between this embodiment and embodiment 5 is that, as shown in fig. 10, the bent portion of the reinforcing member 34 and the reinforcing member 34 in this embodiment form an included angle structure smaller than 90 °, and the bent portion of the reinforcing member 34 is inclined toward the lower form 20.

The setting of middle-upper horizontal muscle 24 in this embodiment can make every truss all keep vertical state, and all trusses form the structure of steel reinforcement cage under the effect of last horizontal muscle 24 and horizontal muscle 21 down, and then make the whole atress performance of truss better. When the floor support plate in the embodiment is hoisted, the joint of the upper transverse rib 24 and the upper chord steel bar 10 can be selected as a hoisting point, the stress intensity is better when the steel bars are concentrated, and the floor support plate can be prevented from being damaged due to hoisting. The upper transverse rib 24 and the lower transverse rib 21 are arranged in a staggered mode, so that the stress strength of the whole truss in all directions is balanced, and the influence caused by the weak stress strength of a certain part in the use process of the floor bearing plate is avoided.
