[0038] Example 1

[0039] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, proposes

[0040] A combined floor deck comprises: a supporting plate 1; a perforated plate 2, which is arranged on the supporting plate 1, the perforated plate 2 and the supporting plate 1 enclose an installation space 1-1, and a filling piece is arranged in the installation space 1-1. The supporting plate 1 has a first buckling edge 3 and a second buckling edge 4 at both ends, and the first buckling edge 3 of one supporting plate 1 is buckled with the second buckling edge 4 of the adjacent supporting plate 1, and the two supporting plates 1 are connected after buckling.

[0041] In this embodiment, in order to solve the problem of poor fireproofing and sound insulation of the open 5-3 type floor deck in the related art, this composite floor deck has stronger heat insulation, sound absorption, noise reduction and fireproofing functions compared with the traditional open 5-3 type floor deck. The traditional open 5-3 floor deck has poor fireproofing performance because the opening 5-3 board is completely exposed to the fire-inducing surface. The combined floor deck is filled with a filler in the installation space 1-1, and the filler is glass wool. The lower side of the glass wool is covered with a layer of perforated plate 2, which improves the fireproofing performance, heat insulation performance and sound absorption performance. The additional layer of perforated plate 2 makes the bottom of the floor deck more flat and beautiful.

[0042] Example 2

[0043] Reference Figure 3~Figure 5 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that it also includes: a track 5, which has two tracks, both of which are arranged on the punching plate 2, and have a plurality of first clamping gaps 5-2. The two tracks 5 form a sliding space 5-1, and the sliding space 5-1 has an opening 5-3; a fastener 6 passes through the opening 5-3, one end of which is slidably and lifted in the sliding space 5-1, and the other end is used to be clamped on the I-beam. One end of the fastener 6 has a plurality of clamping protrusions 6-1. After the fastener 6 is lifted, the clamping protrusion 6-1 is driven to clamp into the corresponding first clamping gap 5-2. After clamping, the fastener 6 and the track 5 are connected. The perforated plate 2 has a mounting hole 2-1, and the track 5 is a metal spring sheet. The track 5 is inserted into the mounting hole 2-1, and one end is set on the perforated plate 2, and the other end is a clamping end 5-4. The first clamping gap 5-2 is located on the clamping end 5-4. After the fastener 6 is lifted, it abuts on the two clamping ends 5-4. After the two clamping ends 5-4 are separated from each other, the clamping protrusion 6-1 is clamped in the first clamping gap 5-2. The fastener 6 includes: a first clamping part 6-2, and the clamping protrusion 6-1 is located on the first clamping part 6-2; a second clamping part 6-3, the first clamping part 6-2 is set on the second clamping part 6-3, and the second clamping part 6-3 has a second clamping gap 6-4, and the second clamping gap 6-4 is used to clamp on the I-beam. The punching plate 2 also has a snap-in hole 2-2. The first snap-in component 6-2 is a metal spring sheet with two sliding ends 2-3. The second snap-in component 6-3 has a slide groove 6-13. The setting direction of the slide groove 6-13 is perpendicular to the setting direction of the track 5. The sliding end 2-3 is slidably set in the slide groove 6-13. After the first snap-in component 6-2 is raised or lowered, the two sliding ends 2-3 slide along the slide groove 6-13, and after sliding, they move closer to each other or away from each other. The snap-in protrusion 6-1 passes through the snap-in hole 2-2 in turn and is snap-in in the installation space 1-1. The second snap-in component 6-3 includes: a mounting seat 6-5, and the slide groove 6-13 is located on the mounting seat 6-5; there are two snap-in spring sheets 6-6, which are set on the mounting seat 6-5. The two snap-in spring sheets 6-6 form a second snap-in gap 6-4, and the I-beam is used to snap in the second snap-in gap 6-4. The clamping spring piece 6-6 has a straight line segment 6-8, a first arc segment 6-9, a second arc segment 6-10 and an oblique line segment connected in sequence, and the two oblique lines form a guide gap, which is used to guide the I-beam into the second clamping gap 6-4. The straight line segment 6-8 is set on the mounting seat 6-5, and the first arc segment 6-9 and the second arc segment 6-10 form the second clamping gap 6-4. It also includes: a plurality of pressing plates 7, which are arranged at intervals on the clamping hole 2-2. After the first clamping member 6-2 is raised or lowered, a pressing plate 7 is pushed to open or close the clamping hole 2-2. The supporting plate 1 is an integrated stamping structure.

[0044] In this embodiment, during the overlapping process of the floor decking in the prior art, workers need to walk on the overlapped floor decking. In the prior art, in order to prevent the floor decking from being misaligned during walking and pouring, the floor decking is often required to be spot welded in areas with small overlapping areas. Spot welding is very cumbersome and the installation period is long. In order to speed up the installation efficiency, this solution designs a quick installation and structure. During the installation process, the second clamping piece 6-3 can be clamped on the I-beam for positioning to prevent the floor decking from being offset during installation. Due to the elastic force of the clamping spring piece 6-6, after installation, the second clamping piece 6-3 of the fastener 6 can be directly fixed on the I-beam. During installation, align the track 5 with the fastener 6, press the support plate 1 downward, and the support plate 1 is pressed downward. During the process, the rail 5 and the fastener 6 slide relative to each other, and the locking protrusion 6-1 slides upward in sequence until it is locked into the locking hole 2-2 to prevent the distance between the support plate 1 and the I-beam from being too large. When the first locking member 6-2 is in the process of being locked into the locking hole 2-2, due to the elastic properties of the first locking member 6-2 and the distance between the locking hole 2-2 and the sliding end 2-3 is smaller than the distance between the first locking member 6-2 and the sliding end 2-3, the first locking member 6-2 can be completely hidden in the installation space 1-1, so the sliding end 2-3 slides in the slide groove 6-13. After sliding, the two sliding ends 2-3 approach each other or move away from each other. The sliding end 2-3 has a protrusion. The function of the protrusion is to ensure that the sliding end 2-3 and the slide groove 6-13 are not separated, and the sliding end 2-3 can also slide in the slide groove 6-13. When the first clamping member 6-2 is completely hidden in the installation space 1-1, the clamping ends 5-4 of the track 5 are far away from each other to the maximum extent. Since the metal spring has a tendency to rebound, the support plate 1 can be fixed after the support plate 1 is installed. When the first clamping member 6-2 passes through and pushes one pressure plate 7 or two pressure plates 7 to rise at the same time, the first clamping member 6-2 is clamped into the clamping hole 2-2. If two pressure plates 7 are pushed up at the same time, the support plate 1 can slide between the two pressure plates 7 until only one pressure plate 7 is lifted up and fixed. If the first clamping member 6-2 directly lifts up one pressure plate 7, the support plate 1 is directly fixed. Since the pressure plate 7 is opened or closed in the vertical direction, it is sufficient to design a guide on the pressure plate 7 and the punching plate 2. When the pressure plate 7 is closed, its own gravity can drive the pressure plate 7 to drop. This structure solves the cumbersomeness of spot welding while ensuring that the overlapped floor decking remains stable and will not be misplaced. At the same time, when the structure is installed, the fastener 6 can be fixed to the center of the floor deck.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
