Description

Technical Field

[0001] This application relates to the technical field of steel bar truss floor slabs, and in particular to a cantilever reinforcement structure for steel bar truss floor slabs. Background Art

[0002] With the continuous development of society, steel bar truss floor slabs have been gradually widely used in construction projects in recent years. As a new type of formwork system, steel bar truss floor slabs can bear the self-weight of wet concrete and construction loads during the construction stage. At the same time, they can serve as lateral supports for steel beams, which is conducive to uniform spacing of steel bars and consistent concrete cover thickness, improving the construction quality of the floor slab, reducing the amount of on-site steel bar binding work, and accelerating the construction progress. When there is a cantilever slab during the installation of steel bar truss floor slabs, temporary support frames need to be set up to ensure the stability and structural integrity of the steel bar truss floor slabs.

[0003] Most of the existing support frames for steel bar truss floor slabs are welded by angle steel or channel steel. Long circular holes for adjusting the installation position are provided on the support frames, and bolts are used to fix the support frames at the installation positions to reinforce the steel bar truss floor slabs.

[0004] The above-mentioned existing technical solutions have the following defects: Vibration is likely to occur during the installation of the support frame, and the bolts and nuts installed in the long circular holes are prone to looseness after being vibrated, reducing the stability of the support position. Moreover, the support frame fixed by bolts is not convenient to adjust the inclination angle of the support, resulting in poor adaptability of the steel bar truss floor slab. Summary of the Utility Model

[0005] This application provides a cantilever reinforcement structure for steel bar truss floor slabs in order to improve the stability and adaptability of the support member to support the truss floor slab.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A cantilever reinforcement structure for steel bar truss floor slabs includes a first fixing frame and a second fixing frame. Both the first fixing frame and the second fixing frame are installed on the construction surface, and the first fixing frame is located above the second fixing frame. A cross brace is fixedly connected to the first fixing frame, and an inclined brace is fixedly connected to the second fixing frame. One end of the inclined brace is fixedly connected to the second fixing frame, and the other end is hinged with an adjusting assembly. A locking assembly is installed at the connection between the adjusting assembly and the cross brace.

[0008] By adopting the above technical solution, the adjusting component at the top of the inclined strut can be moved to slide along the cross strut. After adjusting to a suitable installation angle, the adjusting component is locked and fixed to the cross strut through the locking component. By adjusting the support angle of the cross strut to adapt to the installation angle of the steel bar truss floor slab, the influence of adjusting the support angle on the bolt fixing effect is reduced, the support stability of the inclined strut to the cross strut can be ensured, and the support stability and adaptability of the cantilever reinforcement structure to the steel bar truss floor slab can be improved.

[0009] Optionally, the adjusting component includes a cross bar, a slider and a hinge plate. The cross bar is fixedly connected to the cross strut. The slider is sleeved and slides on the cross bar. The locking component is arranged in the slider and can fix the slider on the cross bar. The hinge plate is fixedly connected to the slider and is slidably connected to the cross strut.

[0010] By adopting the above technical solution, the angle between the hinge plate and the inclined strut can be changed. When installing, the inclined strut is adjusted to the best angle to fully support the cross strut. The stable support of the inclined strut to the cross strut can be ensured while adjusting the angle of the cross strut, the convenience of adjusting the support angle of the cross strut can be improved, and the overall structural stability of the cantilever reinforcement structure can be ensured at the same time.

[0011] Optionally, fixing blocks are fixedly connected to both ends of the cross bar, and the fixing blocks are fixedly connected to the cross strut.

[0012] By adopting the above technical solution, when adjusting the connection position between the slider and the cross bar, the sliding range of the slider can be restricted, ensuring that the slider is within the adjustable range, making it difficult for the slider to disengage from the sliding rod, ensuring the adjustability of the cantilever reinforcement structure, and ensuring the overall structural stability of the cantilever reinforcement structure at the same time.

[0013] Optionally, a guiding groove is formed on the cross strut, a guiding block is fixedly connected to the slider, and the guiding block slides in the guiding groove.

[0014] By adopting the above technical solution, when adjusting the connection position between the slider and the sliding rod, the guiding block can limit and guide the slider, ensuring the smooth sliding of the slider on the cross bar. When the cross strut supports the steel bar truss floor slab, the guiding block can assist the slider in supporting, increasing the stability of the connection between the cross strut and the inclined strut, and ensuring the overall structural stability of the floor slab cantilever reinforcement structure.

[0015] Optionally, an installation cavity is formed in the slider. The locking component includes a bolt. The bolt passes through the installation cavity. A connecting plate is sleeved and threadedly connected to the bolt. The connecting plate is arranged in the installation cavity. A locking rod is welded to the connecting plate. A plurality of locking holes are formed on the cross bar, and the locking rod can be inserted into and clamped in the locking holes.

[0016] By adopting the above technical solution, after the mobile adjustment component adjusts its position relative to the cross brace, it can fix the connection between the diagonal brace and the cross brace, improving the adaptability of the adjusted position of the diagonal brace to support the cross brace. Meanwhile, the locking component can ensure good stability at the connection, enabling the cross brace to stably support the steel bar truss floor slab.

[0017] Optionally, a limiting rod is arranged in the installation cavity. The limiting rod is fixedly connected to the inner wall of the installation cavity, and an elastic member is sleeved on the limiting rod. The elastic member is located between the installation cavity and the connecting plate.

[0018] By adopting the above technical solution, it can ensure that the connecting plate drives the locking rod to insert into the locking hole. After the locking rod inserts into the locking hole, the elastic force of the elastic member can push the connecting plate to prevent the locking rod from sliding out of the locking hole, improving the clamping stability between the locking rod and the locking hole, enhancing the fixing stability of the locking component at the connection between the adjustment component and the cross brace, and improving the overall structural stability of the cantilever reinforcement structure.

[0019] Optionally, a plurality of fixing through holes are penetratingly formed in both the first fixing frame and the second fixing frame.

[0020] By adopting the above technical solution, bolts can pass through different fixing through holes according to the required installation angle, thereby adjusting the fixing position of the first fixing frame and the cross brace or the fixing position of the second fixing frame and the diagonal brace, increasing the adaptability of the cantilever reinforcement structure to the support angle.

[0021] Optionally, both the first fixing frame and the second fixing frame are made of T-shaped steel, and both the cross brace and the diagonal brace are made of angle steel.

[0022] By adopting the above technical solution, the overall structural strength of the cantilever reinforcement structure can be improved, and the support stability of the cantilever reinforcement structure to the steel bar truss floor slab can be increased.

One end of the first fixing bracket 1 away from the wall is fixedly connected to a cross brace 2 by bolts, and one end of the second fixing bracket 11 away from the wall is fixedly connected to a diagonal brace 3 by bolts. One end of the diagonal brace 3 is fixedly connected to the second fixing bracket 11, and the other end is hinged to an adjusting component 4. A locking component 5 is installed between the adjusting component 4 and the cross brace 2. In this embodiment, both the first fixing bracket 1 and the second fixing bracket 11 are made of T-shaped steel, and both the cross brace 2 and the diagonal brace 3 are made of angle steel.

[0035] When installing this cantilever reinforcement structure, the first fixing frame 1 and the second fixing frame 11 are installed and fixed corresponding to each other up and down according to the installation position. Then, one end of the cross brace 2 is fixed on the first fixing frame 1, and one end of the diagonal brace 3 is fixed on the second fixing frame 11 through bolts. Move the adjusting component 4 at the top of the diagonal brace 3 to slide along the cross brace 2. After adjusting to the appropriate installation angle, the locking component 5 locks and fixes the adjusting component 4 and the cross brace 2, ensuring the stable support of the diagonal brace 3 for the cross brace 2 and improving the support stability and adaptability of the cantilever reinforcement structure for the steel bar truss floor slab.

[0036] Refer to Figure 1 , the adjusting component 4 includes a fixing block 41, a cross bar 42, a sliding block 43 and a hinge plate 44. There are two fixing blocks 41 arranged at intervals and both are welded on the inner wall of the right-angle opening of the cross brace 2. The two fixing blocks 41 are respectively located at both ends of the cross brace 2 in the length direction. Both ends of the cross bar 42 are welded on the opposite sides of the two fixing blocks 41, and the length direction of the cross bar 42 is the same as the length direction of the cross brace 2. The sliding block 43 is sleeved and slidably connected to the cross bar 42, and the locking component 5 is arranged in the sliding block 43 and can fix the sliding block 43 on the cross bar 42. The hinge plate 44 is fixedly connected to the bottom of the sliding block 43, and the hinge plate 44 is hinged to one end of the diagonal brace 3 close to the cross brace 2.

[0037] When installing this cantilever reinforcement structure, the sliding block 43 can slide outside the cross bar 42, and at the same time drive the hinge plate 44 at the top of the diagonal brace 3 to slide, so that the angle between the hinge plate 44 and the diagonal brace 3 changes until the diagonal brace 3 is adjusted to the best angle to fully support the cross brace 2 and stably support the cross brace 2, improving the convenience of adjusting the support angle of the cross brace 2 and ensuring the overall structural stability of the cantilever reinforcement structure at the same time.

[0038] Refer to Figure 3 , a guiding block 45 is welded on the side of the sliding block 43 close to the cross brace 2, and a guiding groove 46 is opened on the side of the cross brace 2 close to the guiding block 45. The length direction of the guiding groove 46 is the same as the length direction of the cross brace 2, and the guiding block 45 can fit and slide along the inner wall of the guiding groove 46.

[0039] When installing this cantilever reinforcement structure, the guiding block 45 can limit and guide the sliding block 43, ensuring the smooth sliding of the sliding block on the cross bar 42. When the cross brace 2 supports the steel bar truss floor slab, the guiding block 45 can assist the sliding block 43 to bear, increasing the stability of the connection between the cross brace 2 and the diagonal brace 3 and ensuring the overall structural stability of the floor slab cantilever reinforcement structure.

[0040] Refer to Figure 2 and Figure 3, an installation cavity 51 is provided in the slider 43, and the length direction of the installation cavity 51 is perpendicular to the length direction of the cross bar 42. The locking component 5 includes a bolt 52, the bolt 52 penetrates through the interior of the installation cavity 51, the length direction of the bolt 52 is the same as the length direction of the installation cavity 51, a connecting plate 53 is sleeved and threadedly connected on the bolt 52, the connecting plate 53 is L-shaped, the connecting plate 53 is arranged in the installation cavity 51 and can move along the length direction of the bolt 52, a locking rod 54 is welded to a section of the connecting plate 53 away from the bolt 52, the locking rod 54 is located on the side of the connecting plate 53 close to the cross brace 2, and the locking rod 54 is located within the L-shaped right-angle opening.

[0041] When installing this cantilever reinforcement structure, the adjusting component 4 at the top of the diagonal brace 3 drives the slider 43 to slide on the cross bar 42 according to the required installation position. After adjusting to the required installation angle, rotate the bolt 52 to drive the connecting plate 53 to slide in the installation cavity 51, so that the connecting plate 53 drives the locking rod 54 to be inserted into the locking hole 421, and the connection between the diagonal brace 3 and the cross brace 2 can be fixed. By moving the adjusting component 4 to adjust the fixing position with the cross brace 2, the adaptability of adjusting the supporting position of the diagonal brace 3 to the cross brace 2 can be improved. At the same time, the locking component can ensure good stability at the connection, enabling the cross brace 2 to stably support the steel bar truss floor slab.

At this time, the elastic force of the elastic member 56 can push the connecting plate 53 to ensure that the connecting plate 53 can drive the locking rod 54 to be inserted into the locking hole 421. After the locking rod 54 is inserted into the locking hole 421, the elastic force of the elastic member 56 can push the connecting plate 53 to prevent the locking rod 54 from sliding out of the locking hole 421, improving the clamping stability between the locking rod 54 and the locking hole 421.

[0044] Refer to Figure 4 and Figure 5 , a plurality of fixing through holes 6 are provided in a penetrating manner on the plate surfaces of the first fixing frame 1 and the second fixing frame 11 away from the wall, and the plurality of fixing through holes 6 are spaced along the length direction of the first fixing frame 1 or the second fixing frame 11 where they are located.
