Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a roof slab support structure. Background Technology

[0002] In the field of modern building construction, with the diversification and complexity of architectural designs, the requirements for building structure construction are becoming increasingly stringent. The construction phase of the roof and floor slab structures is one of the key stages of the entire construction process, playing a crucial role in meeting the building's functionality and safety requirements. Especially in some cases, specific construction needs such as the construction of temporary operating platforms or cantilever structures directly impact the building's construction quality and schedule.

[0003] In the construction of roof slab structures, construction workers often employ various methods to build the support system. Some projects choose to use ordinary timber as the main support material, constructing a frame structure that meets the formwork requirements through simple splicing and nailing. This method is convenient and low-cost, and is commonly used in small projects where high precision is not required. Other projects prefer to use steel to fabricate support components, assembling various parts into a stable formwork framework using welding or bolting. Steel has high strength and rigidity, capable of withstanding large loads, and is suitable for large-scale roof slab formwork projects with high load requirements. Additionally, some construction teams combine timber and steel, leveraging the advantages of both to achieve better support results.

[0004] Regarding the aforementioned technologies, whether using wood, steel, or a combination of both, it is difficult to efficiently and evenly transfer the load borne by the roof slab to the main building structure. Especially when facing complex actual working conditions, these traditional formwork structures cannot be flexibly adjusted to adapt to different load distributions and support requirements, which can easily lead to excessive loads in local areas, thereby reducing the stability and safety of the entire formwork system. Utility Model Content

[0005] To overcome the above problems, this application provides a roof slab support structure.

[0006] The roof slab formwork structure provided in this application adopts the following technical solution:

[0007] A roof slab support structure includes embedded components and multiple support components. The embedded components include multiple embedded frames, which are all embedded in a shear wall. The multiple embedded frames are evenly spaced along a first direction. One right-angled side of each embedded frame is close to the outer side of the shear wall and is flush with the outer side of the shear wall.

[0008] The support components correspond one-to-one with the embedded frames. Each support component includes a support base, multiple channel steels, and multiple plywoods. The support base includes a first end face and a second end face, which are perpendicularly connected. The first end face is attached to the right-angled edge of the embedded frame near the outer side of the shear wall. The second end face is near the top of the shear wall. The multiple channel steels are evenly divided into multiple groups, with two channel steels in each group. The multiple groups of channel steels are distributed along a first direction and are all connected to the top of the second end face. Two channel steels in each group are sequentially spaced along a second direction on the second end face. The multiple plywoods are distributed along the first direction, and each plywood corresponds one-to-one with a group of channel steels. The plywoods are connected to the side of the channel steel away from the second end face. The roof cantilever slab is cast on the side of the plywood away from the channel steel.

[0009] By adopting the above technical solution, embedding the pre-embedded frame within the shear wall can stabilize the structural foundation. Connecting the support components one-to-one with the pre-embedded frame allows the load borne by the roof slab to be transferred to the main building structure. The first end face of the support base connects to the pre-embedded frame, and the second end face is close to the top of the shear wall, providing support for the upper channel steel and plywood. Multiple sets of channel steel are distributed along the first direction, with two channel steels in each set spaced apart along the second direction at the top of the second end face, providing stable support for the plywood. The connection between the plywood and the channel steel provides a reliable platform for the pouring of the roof slab, ensuring smooth pouring and facilitating the transfer of the load borne by the roof slab to the main building structure, thus increasing the stability and safety of the entire formwork system.

[0010] In one specific implementation, the support assembly further includes a plurality of reinforcing rods, with each support base corresponding to at least two reinforcing rods. Both reinforcing rods are connected between the first end face and the second end face, and the two reinforcing rods are spaced apart along a first direction. The reinforcing rods are inclined upward from the first end face to the second end face toward the side away from the shear wall.

[0011] By adopting the above technical solution, the reinforcing rod can transmit and distribute the load in all directions, disperse the force applied to the support base and guide it to other support parts, avoid stress concentration, increase the load-bearing capacity of the support base, and effectively improve the structural stability of the support base.

[0012] In one specific implementation, the pre-embedded component further includes multiple pre-embedded parts, with each pre-embedded frame corresponding to one of the pre-embedded parts. Each pre-embedded part includes at least one pre-embedded plate, which is vertically connected to the right-angled side of the pre-embedded frame that is not attached to the shear wall.

[0013] By adopting the above technical solution, the embedded plate and the embedded frame are connected at the right angle side of the embedded frame that is not attached to the shear wall, which can enhance the stability of the embedded frame embedded in the shear wall and make the entire roof cantilever slab formwork structure more stable.

[0014] In one specific implementation scheme, the first end face is slightly smaller than the area of ​​the right angle side of the embedded frame near the outer side of the shear wall. The right angle side of the embedded frame that is flush with the outer side of the shear wall is provided with two connecting grooves on the side near the support base. The two connecting grooves are distributed at intervals along the length direction of their respective right angle sides. The connecting grooves are provided along the first direction.

[0015] The roof slab support structure also includes multiple connecting components, each corresponding to a connecting slot. Each connecting component includes an insert and two connectors. The insert includes an insert seat, which is connected to the first end face near the shear wall. The insert seat can be inserted into the corresponding connecting slot. The top and bottom of the insert seat are respectively fitted to the two slot walls opposite to the connecting slot. The two connectors are connected to the embedded frame and are used to fix the insert seat.

[0016] By adopting the above technical solution, a connecting groove is opened on the right-angle side of the embedded frame, and a connecting component is set. The insert can be inserted into the connecting groove and fixed by the connector. According to the actual working conditions, the position of the insert in the connecting groove can be moved to better and more evenly distribute the load from the upper channel steel, plywood and roof slab, avoid damage caused by local support overload, improve the lateral stiffness of the entire structure, reduce structural deformation caused by dynamic factors, reduce the risk of instability of the support structure during construction, and improve the construction safety factor.

[0017] In one specific implementation, the insert further includes two insertion rods and two insertion springs. The insertion seat has a sliding cavity. One insertion rod passes through the top of the insertion seat, and the other insertion rod passes through the bottom of the insertion seat. The insertion rods are arranged along the distribution direction of the two connecting grooves. The insertion rods are slidably connected to the insertion seat. The two insertion rods move towards or away from each other. The pre-embedded frame has two clearance grooves in the connecting grooves for the insertion rods to be inserted. The two clearance grooves are distributed along the distribution direction of the two connecting grooves. The two sidewalls of the insertion rod distributed along the second direction are respectively abutted against the two groove walls opposite to the clearance grooves. The insertion springs correspond one-to-one with the insertion rods. The insertion springs are located in the sliding cavity and are sleeved on the end of the insertion rod located in the sliding cavity. One end of the insertion spring is connected to the insertion seat, and the other end is connected to the insertion rod.

[0018] By adopting the above technical solution, the insertion rod, in conjunction with the insertion spring and the clearance groove, can be inserted into the clearance groove under the action of the insertion spring when installing the support base. This strengthens the connection stability between the insertion base and the embedded frame, ensuring a firm connection between the support base and the embedded frame. This, in turn, improves the stability and reliability of the entire roof cantilever slab formwork structure. At the same time, it can assist the connecting components in accurately adjusting the installation position of the support base, better adapting to actual working conditions, and evenly distributing the load from above.

[0019] In one specific implementation, the insert further includes a first conical pusher block and a first threaded rod. The first conical pusher block is located in a sliding cavity, and the diameter of the first conical pusher block gradually increases towards the outside of the shear wall along a second direction. One end of the insert rod located in the sliding cavity abuts against the first conical pusher block. The first conical pusher block is slidably connected to the insert seat along the second direction. The first threaded rod passes through the first end face and the insert seat in sequence and then extends into the sliding cavity and is coaxially fixed with the first conical pusher block. The first threaded rod is threadedly connected to the first end face and the insert seat in sequence.

[0020] By adopting the above technical solution, the setting of the first conical pusher block and the first threaded rod allows the insertion rod to be inserted into the clearance groove under the action of the first conical pusher block when the personnel tighten the first threaded rod, thereby realizing a stable connection between the support base and the embedded frame. This further ensures that the formwork structure can efficiently transfer loads under different working conditions, reduce stress concentration, and improve construction quality and safety.

[0021] In one specific implementation, the two connecting members are distributed along the direction of the connecting groove. Each connecting member includes a sliding rod, an abutment plate, an abutment spring, a second conical pusher block, and a second threaded rod. Both sliding rods are located within the connecting groove, and their orientation is consistent with the direction of the connecting groove. The sliding rods are slidably connected to the embedded frame along the direction of the connecting groove. Each of the two abutment plates is connected to one end of the two sliding rods, close to each other. A clamping area for holding the insert seat is provided between the two abutment plates. One side of each abutment plate extends into the clearance groove and slides. The embedded frame has two abutment grooves. The grooves are distributed along the first direction. One end of the sliding rod passes through the embedded frame and extends into the abutment groove. The abutment spring is sleeved on the sliding rod at one end located in the abutment groove. One end of the abutment spring is connected to the embedded frame, and the other end is connected to the sliding rod. The second conical pusher block is located in the abutment groove. The diameter of the second conical pusher block gradually increases towards the outside of the shear wall along the second direction. The outer wall of the second conical pusher block can contact the sliding rod. A threaded plate is connected to the embedded frame at the abutment groove. The second threaded rod passes through the threaded plate and is coaxially connected to the second conical pusher block. The axis of the second threaded rod is perpendicular to the axis of the sliding rod.

[0022] By adopting the above technical solution, the connecting groove is opened in the pre-embedded frame, the insertion seat can be inserted into the connecting groove, the insertion rod cooperates with the clearance groove and the insertion spring, and the first conical pusher block and the first threaded rod can make the insertion rod insert into the clearance groove; on this basis, the sliding rod, the abutment plate, the abutment spring, the second conical pusher block and the second threaded rod of the connecting part, by turning the second threaded rod, make the second conical pusher block move, push the sliding rod, and drive the abutment plate to firmly clamp and fix the insertion seat, further improving the stability of the connection between the support component and the pre-embedded component, and enhancing the stability and reliability of the entire roof cantilever slab formwork structure.

[0023] In one specific implementation scheme, a fixing component is also included, which includes a fixing threaded rod and two fixing nuts. One end of the fixing threaded rod passes through the first end face, the embedded frame and the shear wall in sequence. The fixing threaded rod is slidably connected to the first end face, the embedded frame and the shear wall. Each end of the fixing threaded rod is threadedly connected to one of the fixing nuts.

[0024] By adopting the above technical solution, the integrity and stability of the entire formwork structure can be ensured by passing the fixed threaded rod through the first end face, the embedded frame and the shear wall in sequence and cooperating with the fixing nuts at both ends.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The designed roof slab formwork structure has a first end face of the support base connected to the embedded frame, and a second end face close to the top of the shear wall, providing support for the upper channel steel and plywood; multiple sets of channel steel are distributed along the first direction, and two channel steels in each set are spaced apart at the top of the second end face along the second direction, providing stable support for the plywood; the plywood is connected to the channel steel, providing a reliable platform for the pouring of the roof slab, ensuring the smooth pouring and forming of the roof slab, facilitating the transfer of the load borne by the roof slab to the main building structure, and increasing the stability and safety of the entire formwork system.

The designed roof slab support structure has reinforcing rods that can transmit and distribute loads in all directions, dispersing the force applied to the support base and guiding it to other support parts, avoiding stress concentration, increasing the load-bearing capacity of the support base, and effectively improving the structural stability of the support base.

Consequently, it improves the stability and reliability of the entire roof slab formwork structure. At the same time, it assists the connecting components in precisely adjusting the installation position of the support base, better adapting to actual working conditions, and evenly distributing the load from above.

The embedded frames 11 are all embedded within the shear wall 5, and the embedded parts 12 are evenly spaced along a first direction. In this embodiment, the embedded frame 11 is a right-angled triangle, with one right-angled side of the frame 11 close to and flush with the outer side of the shear wall 5. Each embedded frame 11 corresponds to one embedded part 12. Each embedded part 12 includes at least one embedded plate 121. There are two embedded plates 121, and each embedded plate 121 is a rectangular plate. Both embedded plates 121 are located on the other right-angle side of the embedded frame 11, and the two embedded plates 121 are distributed at intervals along the length of the right-angle side of the embedded frame 11. The setting direction of the embedded plates 121 is perpendicular to the other right-angle side of the embedded frame 11. The embedded plates 121 are welded to the embedded frame 11.

[0041] Reference Figure 1 and Figure 2The support component 2 corresponds one-to-one with the embedded frame 11. The support component 2 includes a support base 21, multiple reinforcing rods 22, multiple channel steels 23, and multiple plywood 24. The support base 21 includes a first end face 211 and a second end face 212, which are vertically arranged and integrally connected. The first end face 211 is attached to the right-angled edge of the embedded frame 11 near the outer side of the shear wall 5 and connected by the connecting component 3, which facilitates the effective transfer of load to the main building structure.

[0049] The implementation principle of the roof slab formwork structure in this embodiment is as follows: the roof slab formwork structure uses pre-embedded components 1 to stably set the structural foundation within the shear wall 5. Support components 2 play a crucial role in transferring and distributing loads. Reinforcing rods 22 enhance the stability of the support base 21. Channel steel 23 and plywood 24 provide a reliable support platform for the pouring of the roof slab 6. Connecting components 3 enable flexible connection and fastening between the support components 2 and the pre-embedded components 1. Fixing components 4 further ensure the integrity of the entire structure. Compared to traditional formwork methods, it can more effectively transfer loads to the main building structure, avoid localized overload, and can be adjusted according to actual working conditions, reducing stress concentration. This improves the construction quality and safety of the roof slab 6, while also increasing construction efficiency and the adaptability of the formwork structure.
