Description

Technical Field

[0001] This utility model relates to the field of building scaffolding technology, and in particular to a prefabricated scaffolding for building construction. Background Technology

[0002] In building installation engineering, hanger systems are crucial facilities supporting various pipelines (such as ventilation ducts, fire hydrants, and cable trays) and equipment. Traditional hangers are mostly installed using on-site welding or prefabricated components. With the development of building industrialization and prefabrication technology, higher demands are placed on the modularity, adjustability, and installation efficiency of hangers. While existing prefabricated hanger technologies have improved construction convenience to some extent, they still have significant shortcomings in structural design, noise control, and long-term durability, mainly manifested in the following typical structures and their defects: Welded fixed hangers are load-bearing frames welded from angle steel or channel steel and directly fixed to the building's roof slab. Their disadvantages include: Non-adjustable: The installation height and horizontal position depend entirely on on-site measurement and welding, and cannot be adapted to later pipeline adjustments or building structure errors; Noise and vibration transmission: Rigid contact between metals causes the vibration of equipment operation to be directly transmitted to the building structure, generating low-frequency noise (common in sensitive places such as hospitals and laboratories). Maintenance is difficult: dismantling and alteration require cutting and welding points, damaging the building surface and easily leading to corrosion. Therefore, a prefabricated hanging system for building construction is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0004] Therefore, one objective of this utility model is to propose a prefabricated hanging frame for building construction, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of the present invention provides a prefabricated hanging frame for building construction, including a top plate and expansion bolts, wherein the expansion bolts are threaded through the top plate and a hanging rod is fixedly connected to the middle of the bottom surface of the top plate; The boom is fitted with a clamp, and the opening of the clamp faces downward. The boom is fitted with a track with the opening facing upwards. There is a gap between the top surface of the inner side of the clamp and the top surface of the track, and a gap between the inner side of the clamp and the side of the track. A slope is provided at the edge of the top surface of the track, and strip-shaped sound-absorbing elements are filled at the corner where the slope meets the inner side of the clamp. The bottom surface of the track has several strip-shaped positioning holes, and the top surface of the clamp and the bottom surface of the track are fastened with fasteners, which are threadedly connected to the hanger rod.

[0006] Preferably, in any of the above embodiments, the top plate is welded to the suspension rod, and the clamp is U-shaped.

[0007] The above technical solution is adopted: This device is a roof hanging frame inside a building. The hanging frame is a prefabricated structure, consisting of four parts. The first part is expansion bolts, which are driven into the roof. The second part consists of the top plate and the hangers. This part is a single piece, and the top plate is fixed with expansion bolts. The third part is the clamp, which is fitted onto the boom and then tightened with fasteners; The fourth part is the track. The bottom surface of the track has several strip-shaped positioning holes for installing specific equipment. The track is tightened with fasteners.

[0008] Preferably, in any of the above solutions, the inner width of the clamp is greater than the outer width of the track, and the clamp is made of stainless steel.

[0009] The core structure of this device, using the above technical solution, consists of: a boom, a clamp, a track, a ramp, a sound-absorbing strip, and fasteners. The track's installation height is flexibly adjustable, offering greater installation adaptability. The clamp and track can be moved on the boom when not fully tightened; once adjusted to the desired height, the fasteners can be tightened. The clamp is designed to be wider, and there is a gap between the top surface of the clamp's inner side and the top surface of the track, as well as a gap between the inner side of the clamp and the side of the track. A slope is provided at the edge of the top surface of the track, and strip-shaped sound-dampening elements, which can be made of POM material, are filled at the corners of the slope and the inner side of the clamp to prevent the metal clamp from directly contacting the track and to prevent friction, noise and wear between the two.

[0010] Preferably, in any of the above solutions, the material of the sound-silencing component is plastic, and the length of the sound-silencing component is the same as the length of the track.

[0011] The above technical solution comprises the following components: a fixed base consisting of expansion bolts. During construction, multiple sets of expansion bolts are driven into the concrete structure of the building's roof.

[0012] Main load-bearing components: including the roof slab and hangers. The hangers are fixedly connected to the center of the bottom surface of the roof slab (preferably welded). The roof slab is securely fixed to the roof using pre-installed expansion bolts.

[0013] The clamping section includes the clamp and fasteners. The clamp is designed as a downward-facing U-shaped structure, typically made of stainless steel. Its inner width is larger than the outer width of the rail. During installation, the clamp is inserted into the lifting rod from below.

[0014] Functional track component: Includes the track, sound-absorbing components, and fasteners. The track is designed as a U-shaped structure with openings at both ends and the top (openings facing upwards). Several parallel, elongated positioning holes are formed on its bottom surface for installing specific pipeline clamps, equipment supports, or hangers. To reduce noise and prevent wear, a continuous slope is machined on the top edge of the track (i.e., the area corresponding to the inner corner of the clamp). Strip-shaped sound-absorbing components (preferably made of POM, with the same length as the track) fill the wedge-shaped space formed between this slope and the inner corner of the clamp. During installation, the track is inserted into the hanger from below, allowing the clamp to naturally cover the track from above.

[0015] Preferably, the track has openings at both ends and above, as is preferred from any of the above options.

[0016] Preferably, of any of the above solutions, the fastener is a washer-type nut, and the height of the clamp and the track is adjustable.

[0017] Core design of the device: A gap is left between the top surface of the inner side of the clamp (above the area where the sound-absorbing component is installed) and the top surface of the track (where the sound-absorbing component is installed). A gap is also left between the inner side of the clamp and the outer side of the track. The strip-shaped sound-absorbing component precisely fills the contact area formed by the inner corner of the clamp and the slope of the top edge of the track, avoiding direct contact between the metal surface of the clamp and the track.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: The building uses prefabricated hanging frames, and the installation height of the rails can be flexibly adjusted, making the installation more adaptable. When the clamps and rails are not tightened, they can be moved on the hanging rods. After adjusting to the required height, the fasteners can be tightened. The clamp is designed to be wider, and there is a gap between the top surface of the clamp's inner side and the top surface of the track, as well as a gap between the inner side of the clamp and the side of the track. A slope is provided at the edge of the top surface of the track, and strip-shaped sound-dampening elements, which can be made of POM material, are filled at the corners of the slope and the inner side of the clamp to prevent the metal clamp from directly contacting the track, thus preventing friction, noise, and wear between the two. This also prevents metal friction noise and wear caused by vibration, deformation, and other factors during long-term use.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] like Figure 1-4 As shown, the building uses a prefabricated hanging frame, including a top plate 1 and expansion bolts 2. Expansion bolts 2 are threaded through the top plate 1, and a hanging rod 3 is fixedly connected to the middle of the bottom surface of the top plate 1. A clamp 4 is fitted onto the boom 3, with the opening of the clamp 4 facing downwards; The rod 3 is fitted with a track 5, the track 5 is open and facing upwards, there is a gap between the top surface of the inner side of the clamp 4 and the top surface of the track 5, and there is a gap between the inner side of the clamp 4 and the side of the track 5. A slope 6 is provided at the edge of the top surface of the track 5, and a strip-shaped sound-dampening component 7 is filled at the corner where the slope 6 meets the inner side of the clamp 4. The bottom surface of the track 5 has several strip-shaped positioning holes 8. The top surface of the clamp 4 and the bottom surface of the track 5 are fastened with fasteners 9, which are threadedly connected to the hanger 3.

[0025] Example 1: The top plate 1 is welded to the hanger rod 3, and the clamp 4 is U-shaped. The inner width of the clamp 4 is greater than the outer width of the track 5, and the clamp 4 is made of stainless steel. The sound-absorbing component 7 is made of plastic, and its length is the same as that of the track 5. The track 5 has openings at both ends and at the top. The fastener 9 is a washer-nut, and the heights of the clamp 4 and the track 5 are adjustable.

[0026] Example 2: This device is a roof hanging frame inside a building. The hanging frame is a prefabricated structure, consisting of four parts. The first part is expansion bolts 2, which are driven into the roof. The second part consists of the top plate 1 and the hanger rod 3. This part is an integral piece, and the top plate 1 is fixed by expansion bolts 2. The third part is the clamp 4, which is fitted onto the boom 3 and then tightened with fastener 9; The fourth part is the track 5. The bottom surface of the track 5 has several strip-shaped positioning holes 8 for installing specific equipment. The track 5 is tightened with fasteners 9.

[0027] The device consists of the following components: a fixed base, which includes expansion bolts 2. During construction, multiple sets of expansion bolts 2 are driven into the concrete structure of the building's roof.

[0028] Main load-bearing components: including the roof plate 1 and the hanger rod 3. The hanger rod 3 is fixedly connected to the center of the bottom surface of the roof plate 1 (preferably welded). The roof plate 1 is securely fixed to the roof by pre-installed expansion bolts 2.

[0029] The clamping section includes clamp 4 and fastener 9. Clamp 4 is designed as a U-shaped structure with the opening facing downwards, and is usually made of stainless steel. Its inner width is designed to be greater than the outer width of the track 5. During installation, clamp 4 is inserted into the hanger rod 3 from below.

[0030] Functional track section: Includes track 5, sound-absorbing component 7, and fasteners 9. Track 5 is designed as a U-shaped structure with openings at both ends and the top (openings facing upwards). Several parallel, elongated positioning holes 8 are formed on its bottom surface for installing specific pipeline clamps, equipment supports, or hangers. To reduce noise and prevent wear, a continuous slope 6 is machined on the top edge of track 5 (i.e., the area corresponding to the inner corner of the clamp 4). The strip-shaped sound-absorbing component 7 (preferably made of POM material, with the same length as track 5) fills the wedge-shaped space formed between this slope 6 and the inner corner of the clamp 4. During installation, track 5 is inserted into the hanger 3 from below, allowing the clamp 4 to naturally cover track 5 from above. A gap is left between the top surface of the inner side of the clamp 4 (above the area where the sound-absorbing component 7 is installed) and the top surface of track 5 (the area where the sound-absorbing component 7 is installed). A gap is also left between the inner side of the clamp 4 and the outer side of track 5. The strip-shaped noise-reducing component 7 precisely fills the contact area formed by the inner corner of the clamp 4 and the slope 6 of the top edge of the track 5, thus avoiding direct contact between the metal surfaces of the clamp 4 and the track 5.

[0031] The working principle of this utility model is as follows: Positioning and drilling: Determine the location of the suspension points on the roof and drill holes. Fixing the base: Drive the expansion bolts 2 into the drilled holes to expand and tighten them into the roof concrete. Installing the main load-bearing structure: Place the roof plate 1 with the suspension rods 3 at the bolt shanks of the expansion bolts 2, and use the matching nuts to firmly press the roof plate 1 onto the roof.

[0032] Pre-fitting the clamp and track: Place the clamp 4 onto the boom 3 from bottom to top. Then place the track 5 onto the boom 3 from bottom to top. At this time, the track 5 is located inside and below the clamp 4, and the sound-absorbing part 7 in the slope area 6 of the top surface of the track 5 is basically in contact with the inner corner of the clamp 4. Before tightening, the clamp 4 and the track 5 can slide freely on the boom 3.

[0033] Preliminary positioning: Pre-screw a washer nut (fastener 9) into the boom 3 (above the clamp 4 and below the track 5) to leave a large gap between it and the top surface of the clamp 4 and the bottom surface of the track 5.

[0034] Height adjustment: According to the actual installation requirements (such as pipeline elevation), use your hands or tools to simultaneously support or lift the combination of clamp 4 and track 5, and move it up and down along the rod 3 to the precise target height position.

[0035] Secure the clamp: Use a tool to tighten the fastener 9 (with washer nut) located on the top surface of the clamp 4. Tighten the nut and press it downwards, pressing the clamp 4 firmly downwards. The sound-dampening part 7 at the inner corner of the clamp 4 is then pressed against the slope 6 of the track 5.

[0036] Secure the rail: Use a tool to tighten the fastener 9 (with washer nut) located on the bottom surface of rail 5. Tighten the nut and push upwards, pressing rail 5 upwards. The slope 6 of rail 5 is pressed against the sound-absorbing component 7 and the clamp 4.

[0037] Complete fixing: At this time, the upper and lower fasteners 9 form a strong clamping force through the clamping clip 4 and the track 5 (with the silent part 7 in the middle transmitting force and isolating friction), which firmly fixes the entire assembly at the target height of the boom 3.

[0038] Equipment installation: Install specific electromechanical pipelines, equipment or decorative components at the positioning hole 8 at the bottom of track 5 using matching hanging bolts or clamps.

[0039] Operating state: The load (equipment weight) is transferred to rail 5 through the connector at the positioning hole 8 on the bottom surface of rail 5, and the load of rail 5 is transferred to the suspension rod 3 through its bottom fastener 9; simultaneously, rail 5 is also subjected to a horizontal torque. The forces acting on rail 5 are mainly decomposed as follows: Vertical force component: continues to be transmitted downwards to boom 3.

[0040] Horizontal force / moment: The force is transmitted from the track 5 to the inner corner of the clamp 4 (constraints on the inner wall and inner top surface) via the sound-absorbing component 7. The clamp 4 then transmits the force to the hanger 3 via its top fastener 9. The presence of the clamp 4 significantly increases the track 5's resistance to lateral displacement and torsion. The entire load is ultimately transmitted from the hanger 3 to the top plate 1 and expansion bolts 2, and then from the expansion bolts 2 to the building structure's top plate. The sound-absorbing component 7 continuously provides metal-to-metal isolation throughout the entire operation, effectively absorbing minor vibrations, preventing frictional noise and wear caused by hard metal-to-metal contact, and improving stability and service life.

[0041] Compared with the prior art, the present invention has the following advantages: The building uses a prefabricated hanging frame. The installation height of the track 5 can be flexibly adjusted, making it more adaptable to different installations. When the clamp 4 and the track 5 are not tightened, they can move on the hanging rod 3. After adjusting to the required height, tighten the fastener 9. The clamp 4 is designed to be wider. At the same time, there is a gap between the top surface of the inner side of the clamp 4 and the top surface of the track 5, and a gap between the inner side of the clamp 4 and the side of the track 5. A slope 6 is provided at the edge of the top surface of the track 5. A strip-shaped sound-dampening element 7, which can be made of POM material, is filled at the corner of the slope 6 and the inner side of the clamp 4 to prevent the metal clamp 4 from directly contacting the track 5, preventing friction, noise and wear between the two, and preventing metal friction noise and wear caused by vibration, deformation and other factors during long-term use.
