Description

Technical Field

[0001] This invention belongs to the field of building construction equipment technology, specifically the cantilever frame of beam-slab overhead structure. Background Technology

[0002] Cantilever scaffolding uses cantilevered steel beams as the load-bearing components of the external frame. During construction, the ends of the cantilevered steel beams are usually fixed to the cantilever beams and structural floor slabs using anchoring components, and steel wire ropes are used to pull the cantilevered steel beams to form a stable supporting structure, providing support for the erection of the scaffolding.

[0003] Due to the complexity of building structures, beam-slab cantilever structures are quite common in construction. When there are beam-slab cantilever structures within the scope of cantilever scaffolding, in order to ensure the consistency of scaffolding erection, when cantilever steel beams need to be installed in the cantilevered parts, large-sized cantilever steel beams are usually selected, and the ends of the cantilever steel beams are extended and anchored to the beam slab. After implementation, because the length of this section of cantilever steel beam is large and the proportion of the cantilever section is large, the cantilever steel beam not only has poor load-bearing capacity when under stress, but also has weak stability at its end anchorage, high construction difficulty, and low safety factor.

[0004] In related technologies, to improve the aforementioned technical problems, the common practice is to add anchor steel beams. These anchor steel beams are then erected on adjacent floor slabs or beams at the suspended section, and the cantilevered steel beams are subsequently installed on them. However, in actual construction, it has been found that, on the one hand, since the cantilevered steel beams are erected on the anchor steel beams, their weight and pressure are applied to the anchor steel beams, thus requiring a high load-bearing capacity. On the other hand, since the anchor steel beams themselves are supported on adjacent floor slabs or beams, the connection stability of the anchor steel beams themselves significantly affects the stability of the cantilevered steel beams. Therefore, this invention proposes a beam-slab overhead structure cantilevered frame to solve the aforementioned technical problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0009] The support system includes at least one anchoring steel beam, which is installed at the beam-slab gap and is fixedly connected to the beam-slab at both ends. The cantilever beam is fixedly connected to the anchoring steel beam.

[0010] A support rod is symmetrically installed at both ends of the anchoring steel beam. A fixing steel cable is fixedly installed on the support rod. The end of the fixing steel cable away from the support rod extends and is fixedly connected to the anchoring steel beam. The support rod, the anchoring steel beam and the fixing steel cable form a triangular structure.

[0011] The two support rods are jointly fixedly installed with a support cable at the ends away from the anchoring steel beam;

[0012] A lifting cable is fixedly installed on a supporting cable, with one end of the lifting cable extending away from the supporting cable and fixed in the middle of the cantilever beam;

[0017] A tensioning cable is provided on the fixed cable, and the end of the tensioning cable extends and is fixed to the take-up reel.

[0018] A through hole is provided on the support rod, and the middle part of the tensioning steel cable extends into the through hole.

[0019] Preferably, a locking block is hinged to the anchoring steel beam, and the locking block and the anchoring steel beam have a conical groove. As the distance between the conical groove and the winding wheel decreases and the diameter of the conical groove increases, an elastic body is slidably installed in the conical groove, and the tensioning steel cable passes through the elastic body. The locking block and the end of the anchoring steel beam away from the hinge point are fixedly connected by a buckle.

[0020] Preferably, the extension rod is hollow, and a tension spring is fixedly installed inside the extension rod. An auxiliary steel cable is fixedly connected to the tension spring, and the auxiliary steel cable passes through the support plate and is fixedly connected to the support steel cable.

[0021] Preferably, the elastic layer has a positioning groove, the depth of which is less than the thickness of the elastic layer, and the diameter of the auxiliary steel cable is greater than the depth of the positioning groove.

[0025] 1.

[0026] 2. The cantilevered frame structure of the beam-slab overhead structure of the present invention, by tightly fitting the support plate and elastic layer with the upper beam-slab, generates downward pressure on both ends of the anchor steel beam, thereby improving the fixing effect between the anchor steel beam and the beam-slab. At the same time, the rod-shaped body formed by the support rod and the extension rod stands between the upper and lower beam-slabs. When the support rod is subjected to tension, under the limiting effect of the upper and lower beam-slabs, the supporting effect of the support rod is effectively enhanced, thereby enhancing the overall bearing capacity of the cantilever frame structure.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1

[0038] Refer to the instruction manual appendix Figure 1-2 The cantilever frame of the beam-slab overhead structure of the present invention includes at least one cantilever beam 1, wherein one end of the cantilever beam 1 is fixed and the other end is suspended.

[0039] It also includes a support system, which is fixedly connected to the cantilever beam 1 and provides a foundation for the installation of the cantilever beam 1;

[0040] The support system includes at least one anchor steel beam 2, which is installed at the beam-slab gap and is fixedly connected to the beam-slab at both ends. The cantilever beam 1 is fixedly connected to the anchor steel beam 2.

[0041] Support rod 21 is symmetrically installed at both ends of anchor steel beam 2. Fixed steel cable 22 is fixedly installed on support rod 21. The end of fixed steel cable 22 away from support rod 21 extends and is fixedly connected to anchor steel beam 2. Support rod 21, anchor steel beam 2 and fixed steel cable 22 form a triangular structure.

[0042] Support cable 23, and the two support rods 21 are fixedly installed with support cable 23 at the ends away from the anchor steel beam 2;

[0043] A lifting cable 24 is fixedly installed on a supporting cable 23, with one end of the lifting cable 24 extending away from the supporting cable 23 and fixed in the middle of the cantilever beam 1.

[0044] A tightening assembly is installed on the support rod 21. The tightening assembly is used to tighten the support steel cable 23 and the fixing steel cable 22 to enhance the support effect on the anchor steel beam 2 and the cantilever beam 1.

[0045] When constructing a cantilevered scaffold, if it needs to be erected on a section of a beam-slab structure, the support system is installed on adjacent beams to support the cantilever beam 1 in the section, enhancing the safety of the cantilever beam 1. Specifically, during construction, according to the pre-designed drawings, the ends of the corresponding number of anchor steel beams 2 are first fixed to the adjacent beams using anchoring components. The anchor steel beams 2 spanning the section of the beam-slab structure provide the installation foundation. Subsequently, the cantilever beam 1 is fixed to the anchor steel beams 2 using anchoring components. At this point, the weight of the cantilever beam 1 and the weight of the scaffolding subsequently installed on the cantilever beam 1 are both applied to the anchor steel beam 2. To enhance the support performance of the anchor steel beam 2, two vertical support rods 21 are installed at both ends of the anchor steel beam 2, and fixing cables 22 are fixedly installed on both the support rods 21 and the anchor steel beam 2. After installation, the fixing cables 22 are connected to the support rods 21 and the anchor steel beam 2. 1. The anchoring steel beam 2 forms a triangular structure, which in turn pulls on the middle part of the anchoring steel beam 2, enhancing the support capacity of the suspended part of the anchoring steel beam 2. At the same time, the support steel cable 23 is fixedly installed at the end of the support rod 21. The length of the support steel cable 23 is the same as the spacing of the support rod 21, so the support steel cable 23 is in a taut state. The support steel cable 23 is fixedly connected to the middle part of the cantilever beam 1 by the lifting steel cable 24. When the end of the cantilever beam 1 is subjected to pressure, the support steel cable 23 and the lifting steel cable 24 can enhance the support capacity of the cantilever beam 1, thereby enhancing the overall load-bearing capacity of the cantilever frame. After the cantilever beam 1 is installed, the tightening component is used to pull and tighten the support steel cable 23 and the fixed steel cable 22, further enhancing the pulling effect of the support steel cable 23 and the fixed steel cable 22 on the anchoring steel beam 2 and the lifting steel cable 24, thereby enhancing the support capacity of the anchoring steel beam 2 and the cantilever beam 1.

[0046] This invention, by setting up a support rod 21 and fixing steel cables 22, supporting steel cables 23 and lifting steel cables 24, utilizes the force transmission effect of the fixing steel cables 22, supporting steel cables 23 and lifting steel cables 24 to cause part of the pressure to be transmitted to the support rod 21. Ultimately, the support rod 21 shares the pressure borne by the anchor steel beam 2 and the cantilever beam 1, enhancing the load-bearing capacity of the anchor steel beam 2 and the cantilever beam 1, thereby enhancing the overall load-bearing capacity of the cantilever frame and thus improving the safety of the cantilever frame.

[0047] Example 2

[0048] Refer to the instruction manual appendix Figure 1-7Based on the previous embodiment, this embodiment further enhances the load-bearing capacity of the cantilever frame by adjusting the structure. The support rod 21 of the present invention is provided with a lifting groove 25, and an extension rod 26 is threadedly connected to the lifting groove 25. The end of the extension rod 26 away from the support rod 21 is rotatably connected to a support plate 3.

[0049] An elastic layer 31 is fixedly installed on the end of the support plate 3 away from the extension rod 26. The elastic layer 31 is made of a wear-resistant elastic material with a rough surface.

[0050] Under the force transmission of the fixed steel cable 22, the supporting steel cable 23, and the lifting steel cable 24, part of the pressure borne by the anchor steel beam 2 and the cantilever beam 1 is transmitted to the support rod 21. To enhance the supporting effect of the support rod 21, an extension rod 26 is installed. During installation, after the anchor steel beam 2 and the cantilever beam 1 are installed, the workers manually rotate the extension rod 26, causing relative movement between the extension rod 26 and the support rod 21. Since the two are connected by threads, the extension rod 26 gradually moves upward from the lifting groove 25 on the support rod 21, causing the support plate 3 installed on the extension rod 26 to gradually approach the upper beam slab and eventually contact the upper beam slab. With continuous rotation of the extension rod 26, the support plate 3 is tightly fitted to the upper beam slab through the elastic layer 31, thereby enhancing the supporting effect of the support rod 21. The anchoring steel beam 2 generates downward pressure at both ends, improving the fixing effect between the anchoring steel beam 2 and the beam plate. At the same time, the rod-shaped body formed by the support rod 21 and the extension rod 26 stands vertically between the upper and lower beam plates. When the support rod 21 is subjected to tension, under the limiting effect of the upper and lower beam plates, the supporting effect of the support rod 21 is effectively enhanced, thereby enhancing the overall bearing capacity of the cantilever frame. It should be noted that the elastic layer 31 used in this invention is made of a rough-surfaced wear-resistant elastic material, such as highly wear-resistant elastic rubber. The presence of the elastic layer 31 enhances the fit and friction between the support plate 3 and the beam plate, effectively reducing the tendency for horizontal relative movement between the support plate 3 and the beam plate, thereby enhancing the clamping and fixing effect on the extension rod 26 and the support rod 21.

[0051] Example 3

[0052] Refer to the instruction manual appendix Figure 1-7 The tightening assembly of the present invention includes a winding wheel 4, and the winding wheel 4 is rotatably installed at both ends of the anchoring steel beam 2. A crank handle 41 is fixedly installed on the winding wheel 4.

[0053] A tensioning cable 42 is provided on the fixed cable 22, and the end of the tensioning cable 42 extends and is fixed on the winding reel 4.

[0054] Through hole 43, the support rod 21 has through hole 43, and the middle part of the tensioning steel cable 42 extends into through hole 43.

[0055] A locking block 5 is hinged to the anchoring steel beam 2. The locking block 5 and the anchoring steel beam 2 are provided with a conical groove 51. As the distance between the conical groove 51 and the winding wheel 4 decreases and the diameter of the conical groove 51 increases, an elastic body 52 is slidably installed in the conical groove 51. The tensioning steel cable 42 passes through the elastic body 52. ​​The locking block 5 and the end of the anchoring steel beam 2 away from the hinge point are fixedly connected by a buckle.

[0056] During installation, after the extension rod 26 drives the support plate 3 to fit tightly against the upper floor slab, the worker manually or via a drive device rotates the winding wheel 4. The rotation of the winding wheel 4 pulls on the tension cable 42, causing it to gradually wind around the winding wheel 4. As the tension cable 42 moves, it pulls on the fixed cable 22, increasing the tension of the fixed cable 22. Furthermore, due to the extension of the middle section of the tension cable 42... When the tension cable 42 is taut, the through hole 43 provides support to the middle of the tension cable 42, causing the tension cable 42 and the fixed cable 22 to form inclined cables with opposite directions on both sides of the support rod 21. These inclined cables then disperse the pressure acting on the middle of the anchor beam 2, enhancing its load-bearing capacity. Simultaneously, during the tightening process, the tension cable 42 extends into the conical groove 51 and penetrates the elastic body 52. When the tension cable 42 is pulled by the winding wheel 4, the friction between the tension cable 42 and the elastic body 52 causes the elastic body 52 to move towards the end with the larger diameter of the conical groove 51. At this time, the tension cable 42 can move. After winding is completed, the fixing cable 22 forms a reverse tension on the tension cable 42, causing the tension cable 42 to have a tendency to move in the opposite direction. At this time, the friction between the tension cable 42 and the elastic body 52 causes the elastic body 52 to have a tendency to move towards the end with the smaller diameter of the conical groove 51. Then, the conical groove 51 compresses the elastic body 52, and the elastic body 52 compresses the tension cable 42, thus fixing the tension cable 42 and facilitating the gradual straightening of the tension cable 42. During the dismantling of the cantilever frame, the workers manually open the buckle and rotate the locking block 5, thereby opening the conical groove 51. At this time, the elastic body 52 is no longer restricted by the conical groove 51 and can slide on the tension cable 42.

[0057] It should be noted that in this invention, both the through hole 43 and the lifting groove 25 are formed on the support rod 21. However, the through hole 43 and the lifting groove 25 are not designed to be conductive. During the production of the support rod 21, the diameter of the support rod 21 can be increased at the location where the through hole 43 is to be formed, thereby causing the through hole 43 and the lifting groove 25 to be misaligned. Alternatively, a metal block can be welded onto the support rod 21, so that a through hole 43 is formed between the metal block and the support rod 21, causing the through hole 43 and the lifting groove 25 to be misaligned, thereby ensuring that the movement of the tension cable 42 and the extension rod 26 does not interfere with each other.

[0058] Example 4

[0059] Refer to the instruction manual appendix Figure 1-7 The extension rod 26 of the present invention has a hollow design, and a tension spring 6 is fixedly installed inside the extension rod 26. An auxiliary steel cable 61 is fixedly connected to the tension spring 6. The auxiliary steel cable 61 passes through the support plate 3 and is fixedly connected to the support steel cable 23.

[0060] The elastic layer 31 has a positioning groove 32, the depth of which is less than the thickness of the elastic layer 31, and the diameter of the auxiliary steel cable 61 is greater than the depth of the positioning groove 32.

[0061] After the support rod 21, extension rod 26, and support plate 3 are fixed between the upper and lower beams, an auxiliary steel cable 61 is installed to enhance the tension on the support cable 23. As the extension rod 26 moves upward, the distance between the support plate 3 and the support cable 23 gradually increases, causing the auxiliary steel cable 61 to be under tension. This causes the tension spring 6 to extend, and under the action of the tension spring 6, the auxiliary steel cable 61 remains taut. With the continuous movement of the extension rod 26, the auxiliary steel cable... The portion of cable 61 protruding from the elastic layer 31 gradually comes into contact with the upper beam slab. Subsequently, the elastic layer 31 deforms, causing the auxiliary steel cable 61 to be clamped between the elastic layer 31 and the upper beam slab, thereby fixing the auxiliary steel cable 61. When the supporting steel cable 23 is subjected to the tension of the lifting steel cable 24, the auxiliary steel cable 61 pulls and fixes the supporting steel cable 23, enhancing the tension of the supporting steel cable 23 on the lifting steel cable 24, thereby enhancing the stability of the cantilever beam 1 and its load-bearing capacity.

[0062] Example 5

[0063] Refer to the instruction manual appendix Figure 1-7 The support rod 21 of the present invention is hinged to the anchoring steel beam 2, and the two support rods 21 on the same anchoring steel beam 2 are staggered in the width direction of the anchoring steel beam 2.

[0064] The support rod 21 is hinged to the two sides with connecting rods 7, and the anchoring steel beam 2 is provided with slots 71, with the connecting rods 7 corresponding to the slots 71.

[0065] By hingedly connecting the support rod 21 to the anchor steel beam 2, the support rod 21 is rotated during the transportation, storage, and installation of the cantilever frame, causing the support rod 21 and the anchor steel beam 2 to move closer to each other. The fixing steel cable 22, support steel cable 23, and lifting steel cable 24 installed on the support rod 21 and the anchor steel beam 2 are all flexible steel cables, which makes it easy to reduce the overall volume of the support system and enhance its transportation and storage convenience. During installation, the support rod 21 is manually rotated, and then the connecting rod 7 hinged on the support rod 21 is inserted into the slot 71, thereby fixing the angle between the support rod 21 and the anchor steel beam 2, thus enhancing the installation convenience of the support system.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
