Description

Technical Field

[0001] This invention relates to the field of building construction technology, and to a steel truss floor slab support device that is easy to install, and particularly to a steel truss floor slab support device that is easy to install and has high construction efficiency. Background Technology

[0002] Steel truss floor decking is a type of unsupported profiled composite floor decking. It is first constructed in a back-end processing area by welding and shaping the upper and lower longitudinal steel bars (i.e., upper and lower chords) with bent small-diameter steel bars to form a small truss (i.e., a steel truss, which is a truss with steel bars as the upper chord, lower chord, and web members, connected by resistance spot welding) to form a structure with a certain rigidity capable of bearing loads. Then, on the construction site, the profiled steel sheets (i.e., steel truss floor decking) are fixed to the steel beams using studs or welding. The small truss is then placed on the profiled steel sheets and bound and welded. After acceptance, it is finished by cast-in-place concrete.

[0003] Currently, the installation of steel truss floor slabs mainly relies on ground-mounted steel pipes for support. This method is cumbersome, inefficient, and time-consuming, increasingly failing to meet the efficiency demands of modern building construction. To improve construction efficiency, CN 206128683 U discloses a steel truss floor slab support device, which includes A-frame trapezoidal legs connected to the steel truss floor slab via a lifting mechanism (jack structure). Furthermore, a positioning and locking mechanism retracts the legs to secure the support frame between the truss floor slab and the lower floor slab. While this significantly simplifies the operation and improves efficiency, the connection to the steel truss floor slab is via a support plate with A-frame trapezoidal legs underneath. This design results in lower stability compared to traditional cage frames. Additionally, multiple steel truss floor slab support devices are required for coordination, and adjacent support devices cannot be mutually fixed, further impacting overall stability.

[0004] Therefore, developing a steel truss floor slab support device that is simple in structure, easy to operate, has high construction efficiency, and good stability is of great practical significance. Summary of the Invention

[0005] In view of the above-mentioned defects in the existing technology, the present invention provides a steel truss floor slab support device with simple structure, easy operation, high construction efficiency and good stability, so as to solve the problems of cumbersome operation, low construction efficiency and poor stability of existing steel truss floor slab support devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An easy-to-install steel truss floor slab support device includes a floor slab and support components;

[0008] The support assembly includes an mounting plate, a support plate, a base plate, a groove, a slider, a connecting rod, a fixing tube, a sliding sleeve, and a first bolt. Four fixing tubes are vertically connected to the four corners of the bottom surface of the floor slab. An mounting plate is provided in the middle of the bottom surface of the floor slab. The mounting plate is slidably connected to the support plate, and the support plate is perpendicular to the floor slab. A base plate parallel to the floor slab is fixed to the side of the support plate away from the mounting plate. Two grooves are opened on the support plate at positions corresponding to the fixing tubes. A slider is provided in the groove. Both ends of the slider are provided with connecting rods. The other end of the connecting rod is provided with a sliding sleeve. The sliding sleeve is fixed by the first bolt.

[0009] The steel truss floor slab support device of the present invention has a simple overall structure. It adopts a traditional vertical support method, which has good stability. Compared with a simple ground-mounted steel pipe support structure, the support plate can also provide sufficient support for the floor slab. The bottom plate under the support plate is in full contact with the ground, which can further improve the stability and bearing capacity of the support device. The support plate is also connected to each fixed pipe through sliders and connecting rods, which can further improve the stability of the support device. At the same time, it is easy to use. The mounting plate and support plate adopt a quick-release design, and most of the others adopt threaded connections, which can quickly install the device. The device can also be reused, which is economical. The application of this steel truss floor slab support device can not only improve the stability of the support, but also greatly improve the construction efficiency, which has great application prospects.

[0010] As a preferred technical solution:

[0011] As described above, a steel truss floor slab support device for easy installation is provided. The floor slab is equipped with a second bolt, and the mounting plate has a first screw hole for mates with the second bolt. The floor slab and the mounting plate are fixed together by the second bolt. Bolt connection is used to facilitate quick disassembly by workers. Of course, those skilled in the art can set the connection method according to actual needs; welding and other methods are also applicable to this invention. However, compared to bolt connection, welding cannot separate the floor slab and the mounting plate, which will cause some inconvenience for transportation and storage.

[0012] As described above, a steel truss floor slab support device for easy installation includes a groove on the mounting plate that mates with a support plate. Tie rods are slidably connected to both sides of the mounting plate along the length of the groove. Springs are fitted over the tie rods. The end of the tie rod furthest from the mounting plate is fixedly connected to a tie plate, and the tie plate is simultaneously connected to the tie rod on the same side. The springs are positioned between the tie plate and the mounting plate. To facilitate quick installation of the support plate, a quick-release design is used. When the tie plate is not pulled up, the tie rods on both sides are close together (less than the thickness of the support plate) under the action of the springs. After pulling up the tie plate and placing the support plate into the groove, the tie rods on both sides press the support plate together under the action of the springs to complete the fixation. The operation is convenient and quick.

[0013] As described above, a steel truss floor slab support device that is easy to install includes a fixed pipe that is threadedly connected to a support rod and the support rod and the fixed pipe are coaxial. The end of the support rod away from the fixed pipe is fixedly connected to a fixed seat. The fixed seat is fixedly connected to the ground by screws to provide sufficient stability for the overall structure and to prevent the fixed seat from swaying horizontally.

[0014] As described above, a steel truss floor slab support device for easy installation includes a first cavity on one side of the floor slab and a plug rod on the opposite side for use with the first cavity. A screw hole perpendicular to the floor slab is formed on the surface of the floor slab opposite the fixing pipe, and a third bolt is installed at the screw hole. A second cavity is formed on the side of the floor slab, and the second cavity communicates with the screw hole. The plug rod engaging with the first cavity enables rapid positioning, improving installation efficiency.

[0015] As described above, a steel truss floor slab support device that is easy to install is provided, wherein the floor slabs of two adjacent steel truss floor slab support devices are fixed to each other by at least one set of connecting assemblies;

[0016] The connecting assembly includes an adjustable-length fixing rod and connecting blocks located at both ends of the fixing rod. The connecting blocks match the second cavity and have second threaded holes for use with a third bolt. That is, the connecting block is fixed to the floor slab by passing the third bolt through the threaded hole and then into the second threaded hole.

[0017] As described above, a steel truss floor slab support device that is easy to install includes two sets of connecting assemblies, namely a first connecting assembly and a second connecting assembly.

[0018] The first connecting assembly includes a spiral tube and two screws arranged on both sides of the spiral tube and threadedly connected to the spiral tube, wherein a first connecting block is connected to the screws on the side away from the spiral tube;

[0019] The second connecting assembly includes a connecting pipe and telescopic rods arranged on both sides of the connecting pipe and sleeved with the connecting pipe. A second connecting block is connected to the telescopic rods on the side away from the connecting pipe. Of course, the scope of protection of this invention is not limited to this. Those skilled in the art can reasonably design the connecting assembly according to actual conditions; this is merely one feasible technical solution.

[0020] As described above, a steel truss floor slab support device that is easy to install is provided with a first anti-slip sleeve and a second anti-slip sleeve respectively on the outside of the threaded pipe and the connecting pipe.

[0021] As described above, a steel truss floor slab support device that is easy to install has a base plate that is parallel to and in full contact with the ground.

[0022] As described above, a steel truss floor slab support device that is easy to install is provided, wherein the sliding sleeve is fitted onto the support rod and fixed to the support rod by a first bolt.

[0023] The above invention has the following advantages or beneficial effects:

[0024] The steel truss floor slab support device of the present invention has a simple overall structure. It adopts a traditional vertical support method, which has good stability. Compared with a simple ground-mounted steel pipe support structure, the support plate can also provide sufficient support for the floor slab. The bottom plate under the support plate is in full contact with the ground, which can further improve the stability and bearing capacity of the support device. The support plate is also connected to each fixed pipe through sliders and connecting rods, which can further improve the stability of the support device. At the same time, it is easy to use. The mounting plate and support plate adopt a quick-release design, and most of the others adopt threaded connections, which can quickly install the device. The device can also be reused, which is economical. The application of this steel truss floor slab support device can not only improve the stability of the support, but also greatly improve the construction efficiency, which has great application prospects.

[0032] The structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0033] Example 1

[0034] A steel truss floor slab support device has been specifically used in the EPC project of Nanjing International Precision Medicine Center, such as... Figure 1 and 3 As shown, it includes a floor slab (second floor slab 2) and supporting components;

[0035] The support assembly includes a mounting plate 31, a support plate 32, a base plate 33, a slide groove 34, a slider 35, a connecting rod 36, a fixing pipe 37, a sliding sleeve 38, and a first bolt 39. Four fixing pipes 37 are vertically connected to the four corners of the bottom surface of the floor slab (second floor slab 2). The fixing pipes 37 are threaded to the support rod 10, and the support rod 10 and the fixing pipes 37 are coaxial. The end of the support rod 10 away from the fixing pipe 37 is fixedly connected to a fixing seat 11. The fixing seat 11 is fixedly connected to the ground by screws 12. A second bolt 4 is provided on the floor slab. A first screw hole 5 is provided on the mounting plate to cooperate with the second bolt 4. The middle part of the bottom surface of the floor slab is fixed to the mounting plate 31 by the second bolt 4.

[0036] Mounting plate 31 is slidably connected to support plate 32, and support plate 32 is perpendicular to floor slab 31. Figure 2As shown, a groove 8 is provided on the mounting plate 31 to cooperate with the support plate 32. Pull rods 6 are slidably connected to both sides of the mounting plate 31 along the length of the groove 8. A spring 7 is provided on the pull rod 6. The end of the pull rod 6 away from the mounting plate is fixedly connected to the pull plate 9, and the pull plate 9 is simultaneously connected to the pull rod 6 on the same side. The spring 7 is arranged between the pull plate 9 and the mounting plate 31.

[0037] A base plate 33 parallel to the floor slab (fully in contact with the ground) is fixed to the side of the support plate 32 away from the mounting plate 31. Two sliding grooves 34 are opened on the support plate 32 at positions corresponding to the fixing pipe 37. A slider 34 is provided in the sliding groove 34. Both ends of the slider 35 are provided with connecting rods 36. The other end of the connecting rod 36 is provided with a sliding sleeve 38. The sliding sleeve 38 is fitted onto the support rod 10 and fixed to the support rod 10 by the first bolt 37.

[0038] like Figures 4-5 As shown, two adjacent sets of steel truss floor slab support devices (i.e., two floor slabs in total, namely the first floor slab 1 and the second floor slab 2) are positioned by a first cavity and a plug rod. A first cavity 13 is provided on one side of each floor slab (first floor slab 1 and second floor slab 2), and a plug rod 14 for use with the first cavity 13 is provided on the opposite side. A screw hole perpendicular to the floor slab is provided on the surface of the floor slab opposite to the fixing pipe, and a third bolt 15 is provided at the screw hole. A second cavity 16 is provided on the side of the floor slab, and the second cavity communicates with the screw hole. The two adjacent sets of steel truss floor slab support devices are connected by two sets of connecting assemblies (a first connecting assembly and a second connecting assembly). The components are mutually fixed. The first connecting component includes a screw tube 19 and two screw rods 18 arranged on both sides of the screw tube 19 and threadedly connected to the screw tube 19. The screw rods 18 are connected to a first connecting block 17 on the side away from the screw tube 19. The second connecting component includes a connecting pipe 23 and telescopic rods 25 arranged on both sides of the connecting pipe 23 and sleeved with the connecting pipe 23. The telescopic rods 25 are connected to a second connecting block 22 on the side away from the connecting pipe 23. The first connecting block 17 and the second connecting block 22 are matched with the second cavity 16 and have a second screw hole 21 on them for use with the third bolt 15. The screw tube 19 and the connecting pipe 23 are respectively fitted with a first anti-slip sleeve 20 and a second anti-slip sleeve 24.

[0039] The operating steps for the above-mentioned steel truss floor slab support device are as follows:

[0040] The user places the mounting plate at the bottom of the first floor slab, then rotates the second bolt until it enters the interior of the first floor slab and the mounting plate. Next, the user pulls the pull plate, which moves the pull rod and extends the spring, placing the support plate into the groove. Releasing the pull plate allows the pull rod to enter the support plate under the spring force, thus firmly fixing the support plate in place and preventing it from moving or sliding. With the support of the base plate, the support plate provides firm support to the first floor slab. Simultaneously, the support rod passes through the sliding sleeve. Rotating the support rod allows it to engage with the sliding sleeve. The fixed tubes are tightly connected, and the third bolt is rotated to allow it to enter the interior of the support rod. The support rod is then tightly connected to the sliding sleeve. The user then uses a tool to rotate the screw, allowing it to enter the interior of the fixed seat and the ground, thus ensuring a tight connection between the fixed seat and the ground. This allows the support assembly to provide stable support for the first and second floor slabs. When multiple sets of steel truss floor slab support devices need to be spliced, the first cavities and inserts of adjacent steel truss floor slab support devices are interlocked, and then the connecting assemblies are used to fix the adjacent steel truss floor slab support devices.

[0041] Verification has shown that the steel truss floor slab support device of the present invention is stable and safe, with good engineering quality and significantly shortened construction period, and has substantial features and significant technical progress compared with traditional methods.
