Description

Technical Field

[0001] The invention relates to the technical field of assembled buildings, and in particular to a detachable rib beam bracket for a combined floor. Background Art

[0002] Composite floor refers to a floor system that uses steel beams and concrete slabs. Compared with concrete floors that use concrete beams and concrete slabs, composite floor has the advantages of small beam section height, reasonable space performance utilization, and fast construction speed. Therefore, composite floor is being used more and more widely in the field of construction engineering. The concrete slabs of existing composite floors often use cast-in-place concrete slabs and prefabricated composite slabs. However, whether it is a cast-in-place concrete slab or a prefabricated composite slab, in the actual construction process, it is necessary to set up a supporting scaffolding between the bottom of the current concrete slab and the top of the lower concrete slab, so as to transfer the load during construction to the completed concrete slab of the lower layer.

[0003] Patent document CN216713527U, published on June 10, 2022, discloses an assembled flat floor, the technical solution of which includes: a number of longitudinal beam truss plates arranged side by side, a number of cross beam truss plates arranged at intervals between two adjacent longitudinal beam truss plates, the cross beam truss plates are arranged perpendicular to the longitudinal beam truss plates, the cross beam truss plates and the longitudinal beam truss plates are both overlapped on the columns, and the columns are provided with vertically arranged vertical ribs. Its beneficial effect is that by pre-laying the longitudinal beam truss plates and the cross beam truss plates, and then pouring concrete, the bottom of the floor can be prevented from being uneven. The beam truss plate and the composite plate are integrated into one, and the upper and lower surfaces of the floor can be guaranteed to be flush. During the construction process, the longitudinal beam truss plate can also be used as a support plate for the transverse beam truss plate and the composite plate, which can effectively save the number of scaffolding supports and save labor. The flush upper and lower surfaces of the floor can save the later ceiling decoration, and the overall construction efficiency of the floor is improved, and the building height can be reduced. The beams and plates are both plates, and the production and construction are efficient.

[0004] In the above-mentioned prior art, the number of scaffolds used in the construction of the floor is reduced through structural improvements, but in essence, the scaffolds are still needed for support. Based on the force-bearing characteristics of the supporting scaffolds, which are slender rods, they are very prone to instability when subjected to force, especially for buildings with high floor heights. The height of the supporting scaffolds must also be increased accordingly, resulting in its stability being difficult to ensure; and the supporting points of the scaffolds need to rely on the completed concrete slabs of the lower floor, causing the construction process of the floor to always be carried out in order of floor height, thereby extending the construction time. Therefore, a detachable rib beam bracket for a combined floor is urgently needed to solve the above problems. Summary of the invention

[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] The detachable rib beam bracket for the composite floor can directly place the support rod members on the beam body to form a support frame by setting support members and lap members for the support operation of the floor construction, eliminating the use of traditional scaffolding, and there is no problem of instability of the slender rods of the traditional supporting scaffolding, so the construction safety is greatly improved; at the same time, because the fulcrum of the support frame is set on the beam body, it no longer relies on the support of the lower floor slab like the traditional supporting scaffolding, so that multiple floors can be constructed at the same time, which greatly improves the construction speed; in addition, after the floor construction is stable, the support members can be removed from the beam body, making the support rod members easy to disassemble and reused, thereby reducing costs.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] See also Figure 1-12 A detachable rib beam support for a composite floor provided in an embodiment of the present invention is used to be built between at least two beam bodies 1, and includes: a support member 2, which is detachably arranged on the beam body 1; a support member 3, both ends of which are provided with overlapping members 4 matching the support member 2; a plurality of support members 3 are provided, and they are overlapped with at least two beam bodies 1 to form a support frame for supporting the construction of the floor.

[0038] Specifically, the beam body 1 is set as a steel beam based on an I-beam, which is arranged horizontally and forms a three-dimensional steel structure frame with other vertical building structures. The support member 2 is connected to the lower side of the upper steel plate of the I-beam steel beam, and one end extends horizontally out of the shielding range of the upper steel plate of the I-beam steel beam; multiple support members 2 are arranged on the same beam body 1, and are arranged at intervals. The support rod member 3 is a wooden rod with high tensile and compressive strength, good mechanical properties and light weight; the support rod member 3 is horizontally arranged between the two beam bodies 1, and multiple support rod members 3 are arranged at the same horizontal height; during the construction of the floor, it is necessary to use templates and steel mesh cages and other structures, and these template mold structures are directly supported on the support frame. The lap joint 4 is overlapped on the upper side of the end of the support member 2 extending out of the beam body 1, and the support rod member 3 is supported and suspended between the two beam bodies 1 by overlapping the lap joints 4 at both ends with the support member 2. In actual use, the technical solution is first installed at a designated position on the beam body 1, then the support rod 3 is hoisted between the two beam bodies 1, the lap joints 4 at both ends are located above the support rods 2 on both sides, and then the support rod 3 is slowly lowered so that the lap joints 4 are smoothly overlapped above the support rod 2, and the support rod 3 is smoothly supported and suspended between the two beam bodies 1. When multiple support rods 3 are built, a support frame is formed between the two beam bodies 1 for supporting operations in floor construction, eliminating the use of traditional scaffolding, and there is no problem of instability of the slender rods of the traditional supporting scaffolding, and the construction safety is great. At the same time, since the fulcrum of the support frame is set on the beam body 1, it no longer relies on the support of the lower floor slab like the traditional support scaffolding, so it is possible to construct multiple floors at the same time, which greatly improves the construction speed; in addition, since the lap joint 4 is overlapped on the support member 2, the construction of the floor is located above the support rod member 3. When the floor construction is stable, the support member 2 can be removed downward from the beam body 1, so that the support rod member 3 loses support, and the support rod member 3 can be removed downward. The disassembled support member 2 and the support rod member 3 can be reused, which reduces the cost; at the same time, during the above-mentioned disassembly process of the support rod member 3, it is necessary to pay attention to the falling of the support rod member 3.

[0039] Compared with the prior art, the detachable rib beam bracket for a combined floor proposed in an embodiment of the present invention can directly place the support rod member 3 on the beam body 1 to form a support frame by setting the support member 2 and the lap joint member 4, so as to be used for the support operation of the floor construction, eliminating the use of traditional scaffolding, and there is no problem of instability of the slender rods of the traditional supporting scaffolding, and the construction safety is greatly improved; at the same time, because the fulcrum of the support frame is set on the beam body 1, it no longer relies on the support of the lower floor slab like the traditional supporting scaffolding, so that multiple floors can be constructed at the same time, which greatly improves the construction speed; in addition, after the floor construction is stable, the support member 2 can be removed from the beam body 1, so that the support rod member 3 is easy to disassemble and can be reused, thereby reducing costs.

[0040] As the preferred technical solution of this embodiment, the support member 2 includes a support plate 201 and a reinforcing rib 202. The support plate 201 is connected to the beam body 1 by a bolt structure, and the reinforcing rib 202 is vertically fixedly connected to the support plate 201. Specifically, the support plate 201 is fitted with the lower side of the upper steel plate of the I-beam steel beam, and a plurality of drill holes are opened on the support plate 201. A plurality of drill holes are also opened on the upper steel plate of the I-beam steel beam. The two groups of drill holes correspond to each other up and down. The bolts pass through a pair of corresponding drill holes from top to bottom, and the nuts are threadedly sleeved on the lower ends. The nuts are tightened to tightly connect the support plate 201 with the upper steel plate of the I-beam steel beam. When the support member 2 is disassembled, the nuts are loosened and then unscrewed and separated from the bolts. Then, the support plate 201 can be separated downward from the upper steel plate of the I-beam steel beam, that is, the support member 2 is separated from the beam body 1, the lap joint 4 loses support, and the support rod member 3 can be disassembled downward and leave the beam body 1. The reinforcing rib 202 is usually a straight plate and is welded at the middle position of the lower side of the support plate 201. The extension direction of the support plate surface corresponds to the extension direction of the support rod member 3 to better strengthen the supporting effect of the support member 2 on the support rod member 3.

[0041] As the preferred technical solution of this embodiment, the end of the lap joint 4 is provided with an overlap portion 401 which overlaps and fits with the support plate 201, and side stop portions 402 are provided on both sides of the overlap portion 401. Specifically, the lap joint 4 is cylindrical; the overlap portion 401 is the upper wall portion of the cylindrical lap joint 4, and its length in the extension direction of the support rod member 3 is the longest on the lap joint 4, and correspondingly, the corresponding length of the lower wall portion of the lap joint 4 is the shortest; the difference in length between the upper and lower walls of the cylindrical lap joint 4 facilitates the lap joint 4 to overlap from top to bottom on the support member 2. The side stop portion 402 is the side wall of the cylindrical lap joint 4, and its inner wall width matches the width of the portion of the support plate 201 extending out of the beam body 1. When the overlap portion 401 overlaps and fits on the support plate 201, the side stop portions 402 limit the opposite sides of the support plate 201 to reduce the possibility of the lap joint 4 shaking left and right on the support member 2.

[0042] As a preferred technical solution of this embodiment, a plug 301 is provided at the end of the support rod member 3, and the lap joint member 4 is sleeved on the plug 301 and connected to the plug 301 through a bolt structure. Specifically, the plug 301 is made of a wooden component that is integrated with the support rod member 3; the shape of the plug 301 matches the cylindrical lap joint member 4; a transverse through hole is provided on the plug 301, and transverse through holes are also provided on the two side walls of the lap joint member 4. The two groups of through holes correspond to each other transversely after the lap joint member 4 is sleeved with the plug 301, and the bolt passes through a group of transverse corresponding through holes from an outer side of the lap joint member 4, and then passes through the end of the lap joint member 4 on the other side again. The bolt is threadedly sleeved The nut is then tightened to tightly connect the lap joint 4 and the plug 301; when the lap joint 4 is disassembled, the nut is loosened and then unscrewed to separate it from the bolt, and then the bolt is pulled out of the lap joint 4 and the through hole on the plug 301, and the lap joint 4 can slide away from the end of the plug 301. This disassembly structure allows the lap joints 4 at both ends of the support rod member 3 to be freely disassembled and installed, and then support rod members 3 and lap joints 4 with different length specifications are set in combination, or lap joints 4 with different lengths are set in combination with the support rod member 3, so that the overall length of the support rod member 3 and the lap joint 4 can be changed to meet the requirements of different support spans under actual construction conditions.

[0043] In another embodiment of the present invention, a triangular support body is formed between two adjacent support rods 3 and one side beam body 1, and the support frame is formed by splicing a plurality of triangular support bodies. Specifically, a plurality of support rods 3 are arranged obliquely on the horizontal plane between the two beam bodies 1 and form an M shape; the two support rods 3 at the edges are arranged perpendicular to the two beam bodies 1; the two groups of support members 2 distributed on the two beam bodies 1 are arranged alternately, where the support members 2 are arranged in a V shape, and the ends of two support rods 3 close to the same side beam body 1 and forming a corner of the triangular support body are overlapped on the same support member 2; the support rods 3 overlapping the beam body 1 in the manner of forming a triangular support body, on the one hand, enhance the structural stability, and on the other hand, compared with a single support rod 3 corresponding to two support members 2, reduce the number of support members 2 set, thereby reducing the number of installation and disassembly of the support members 2, that is, improve the installation and disassembly efficiency of the support members 2.

[0044] As a preferred technical solution of this embodiment, two lap joints 4 are closely attached to form a corner of a triangular support body, and a fastening assembly is arranged on the inner side. Specifically, the angle of the corner of the triangular support body formed by the two lap joints 4 is set to 20-40 degrees; the fastening assembly further limits the position of the lap joint 4 by squeezing the inner angle between the two lap joints 4, and fastens the lap joint 4 to the support member 2, so that the overall support frame is further stabilized, thereby preventing the lap joint 4 from jumping or flipping on the support member 2 due to the force on the support rod member 3 during the subsequent floor construction process, thereby preventing the risk of detachment.

[0045] As a further preferred technical solution of this embodiment, the fastening assembly includes two extrusion blocks 5 movably arranged on the inner side of one corner of the triangular support body, and the extrusion blocks 5 are movably connected with the lap joint 4. Specifically, a slide plate 11 is fixedly arranged on the extrusion block 5, and a slide groove 12 matching the slide plate 11 is arranged in the upper wall of the lap joint 4. The slide groove 12 is arranged near an end surface of the inner side of the triangular support body and connected to the side wall of the lap joint 4. A connected displacement groove 13 is arranged on the upper side of the slide groove 12, and a displacement bar 14 movably connected with the displacement groove 13 is fixedly arranged on the slide plate 11. The width of the displacement bar 14 is smaller than that of the displacement groove 13; the arrangement of the slide plate 11 and the slide groove 12 allows the extrusion block 5 to move horizontally relative to the lap joint 4; the arrangement of the displacement groove 13 and the displacement bar 14 limits the range of movement of the extrusion block 5 relative to the lap joint 4, specifically, the extrusion block 5 can move along the side wall direction of the lap joint 4, and can also move closer to or away from the side wall direction of the lap joint 4. The extrusion blocks 5 are arranged in a triangular or trapezoidal shape. When the two extrusion blocks 5 move synchronously toward an inner corner of the triangular support body, their adjacent end faces can fit together, so that the two extrusion blocks 5 form a wedge block to extrude the inner corner of the triangular support body. Under the action of this extrusion force, the lap joint 4 and the support member 2 are tightly pressed together, and the two lap joints 4 approaching each other are limited to each other by means of the wedge block, thereby stabilizing the overlapping relationship between the support member 2 and the lap joint 4. In actual use of the present technical solution, the support rod member 3 is overlapped on the V-shaped support member 2 by means of the overlap member 4, and two adjacent support rod members 3 and a side beam body 1 form a triangular support body. There are two extrusion blocks 5 between the two overlap members 4 that are close to each other in the triangular support body, so that the two extrusion blocks 5 move synchronously toward the inner corners of the corresponding triangular support body, and the two extrusion blocks 5 form a wedge block to squeeze the inner corners of the triangular support body, so that the two overlap members 4 are close to the same support member 2, and the two overlap members 4 that are close to each other are limited to each other by means of the wedge block, thereby stabilizing the overlap relationship between the support member 2 and the overlap member 4, making the overall support frame further stable, and preventing the overlap member 4 from jumping or flipping on the support member 2 due to external force.

[0046] In addition, only one extrusion block 5 is arranged between two overlapping members 4 close to each other on a support member 3 located at the edge and another adjacent support member 3. The single extrusion block 5 can also extrude the inner angle of the triangular support body formed between two adjacent support members 3 at the edge to stabilize the overlapping relationship between the support member 2 and the overlapping member 4 here.

[0047] As a further preferred technical solution of this embodiment, the adjacent side of the two extrusion blocks 5 is provided with tooth surfaces that can bite each other. Specifically, the setting of the tooth surfaces allows the two extrusion blocks 5 to form a wedge block through tooth surface bite when they move toward an inner corner of the triangular support at the same time, so that they can move synchronously to extrude the inner corner of the triangular support in the subsequent process. Furthermore, the tooth surface provided on the adjacent side of the extrusion block 5 is preferably a soft tooth surface, which can be made of rubber or other materials; the setting of the soft tooth surface allows the two extrusion blocks 5 to move toward an inner corner of the triangular support at the same time and form a wedge block through tooth surface bite, and when the inner corner of the triangular support is extruded, the tooth surface can be extruded and deformed, so that the wedge block further extends into the inner corner of the triangular support to ensure the realization of the extrusion force. In addition, for the two support rods 3 at the edge, the single extrusion block 5 provided in the triangular support formed by them squeezes the outer wall of the lap joint 4 at the end of the most edge support rod 3 through its soft tooth surface to increase friction, and at the same time, it also deforms to ensure the realization of the extrusion force.

[0048] As a further preferred technical solution of this embodiment, a groove 6 is provided on one side of the extrusion block 5 close to the lap joint 4, an elastic member 7 is provided in the groove 6, the free end of the elastic member 7 is against the lap joint 4, and a slot 8 matching the elastic member 7 is provided on the lap joint 4. Specifically, the elastic member 7 can be completely retracted into the groove 6 when subjected to external pressure, that is, it does not protrude from the surface of one side of the extrusion block 5 close to the lap joint 4, so that the surface of the extrusion block 5 can be attached to the lap joint 4; the end of the elastic member 7 connected to the groove 6 is arranged close to the outer end of the lap joint 4, and the free end of the elastic member 7 is away from the outer end of the lap joint 4. A groove 6 is arranged to protrude outward; the slot 8 is arranged to be a serrated groove, and its serrations are directed to hinder the movement of the elastic member 7 in the direction away from the outer end of the lap joint 4; no less than two elastic members 7 are arranged, and the width of the multiple elastic members 7 is larger the closer to the outer end of the lap joint 4, and accordingly, multiple slots 8 are also arranged, corresponding to the elastic members 7 one by one, and the width is also matched with the corresponding elastic members 7, so that when the elastic member 7 close to the outer end of the lap joint 4 passes through the slots 8 corresponding to other elastic members 7 away from the outer end of the lap joint 4, it can pass against the surface of the lap joint 4 without being affected by these slots 8 that do not correspond to it. When the elastic member 7 does not correspond to the corresponding slot 8, its elasticity abuts against the surface of the lap joint 4, so that the extrusion block 5 does not fit the surface of the lap joint 4. Therefore, when the two extrusion blocks 5 move toward one corner of the triangular support body at the same time, the two extrusion blocks 5 can first bite with the tooth surface to form a wedge block. Among them, when the two extrusion blocks 5 do not form a wedge block, it is the first state of the extrusion block 5, and when the two extrusion blocks 5 form a wedge block, it is the second state of the extrusion block 5. Then, when the two extrusion blocks 5 in the wedge block state continue to move toward one corner of the triangular support body, the elastic member 7 first does not correspond to the slot 8 corresponding to it. Correspondingly, it begins to be squeezed into the groove 6 and store elastic potential energy due to the contact with the surface of the lap joint 4. When the wedge block squeezes the inner corner of the triangular support body with the help of the surface of the extrusion block 5, the elastic member 7 corresponds to its corresponding slot 8, and releases the elastic potential energy to embed into the slot 8, and limits the movement of the wedge block away from the inner corner of the triangular support body, so that the wedge block can be stably squeezed in the inner corner of the triangular support body, and with the setting of the soft tooth surface, the wedge block can be further clamped in the inner corner of the triangular support body. In this process, the wedge block is in the third state of the extrusion block 5 when it squeezes the inner corner of the triangular support body stably.

[0049] In the above embodiments, the process of squeezing and stabilizing the two lap joints 4 by the extrusion block 5 can go through three states, specifically: when the extrusion block 5 is in the first state, the elastic member 7 is free to tilt outward from the groove 6 and abut against the outer wall of the lap joint 4, so that a gap is left between the surface of the extrusion block 5 close to the lap joint 4 and the lap joint 4, and the extrusion block 5 moves along the surface of the lap joint 4 while maintaining this gap; when the extrusion block 5 is in the second state, the extrusion block 5 still maintains the above-mentioned gap between the surface of the lap joint 4, but the two extrusion blocks 5 are engaged through the adjacent tooth surfaces to form a wedge block that matches the inner angle of the triangular support body; when the extrusion block 5 is in the third state, the two extrusion blocks 5 remain engaged to form a wedge block, the surface of the extrusion block 5 close to the lap joint 4 remains in contact with the lap joint 4, and the elastic member 7 corresponds to its corresponding slot 8 and is embedded in the corresponding slot 8.

[0050] The process of the extrusion block 5 switching from the first state to the second state is as follows: under the support of the free tilting of the elastic member 7, the two extrusion blocks 5 keep the gap with the corresponding lap joint 4 while simultaneously approaching the inner corner of the triangular support body, and then they can bite through the adjacent tooth surfaces to form a wedge block. The process of the extrusion block 5 switching from the second state to the third state is as follows: the wedge block composed of the two extrusion blocks 5 continues to move toward the inner corner of the triangular support body. As its inner angle continues to narrow, the elastic member 7 begins to bend and shrink into the groove 6 under the action of the surface resistance of the lap joint 4 and stores elastic potential energy. The gap between the extrusion block 5 and the lap joint 4 continues to shrink. When the wedge block moves to squeeze the surface of the lap joint 4 through the surface of the extrusion block 5, the elastic member 7 begins to correspond to the corresponding slot 8. Then, the elastic member 7 releases the elastic potential energy to embed into the slot 8, thereby preventing the wedge block from moving back. Further, in conjunction with the setting of the soft tooth surface, the wedge block squeezes the soft tooth surface to further penetrate into the inner corner of the triangular support body to ensure the realization of the extrusion force. In addition, after the support rod member 3 is disassembled, the two extrusion blocks 5 are automatically separated, and the elastic member 7 can be automatically relaxed to facilitate the extrusion block 5 to return to the first state.

[0051] As a further preferred technical solution of this embodiment, the fastening assembly includes a buckle 9 movably arranged on the side wall of the lap joint 4 movably connected to the extrusion block 5, and a functional groove 10 corresponding to the buckle 9 is arranged at the end of the support member 2. Specifically, a first slide 15 connecting the end of the support member 2 is arranged on the side of the functional groove 10 close to the buckle 9, and a locking block 16 is movably arranged in the functional groove 10, and a protrusion 17 is arranged on one side of the locking block 16. A sliding groove 18 matching the protrusion 17 is arranged in the support member 2, and a spring 19 is arranged in the sliding groove 18 connected to the protrusion 17, and a second slide 20 matching the locking block 16 is arranged on the inner wall of the lap joint 4 opposite to the buckle 9. The buckle 9 is capsule-shaped, with spherical ends and a convex ring in the middle, and a movable cavity matching the convex ring is provided in the side wall of the lap joint 4; the length of the buckle 9 is not less than the thickness of the side wall of the lap joint 4; the length of the locking block 16 matches the width of the part of the support member 2 inserted into the lap joint 4; the setting of the spring 19 keeps pushing the protrusion 17 so that the protrusion 17 remains against one end of the inner wall of the sliding groove 18, and then both ends of the locking block 16 are just received in the functional groove 10 without protruding from the side wall of the support member 2.

[0052] In actual use of the present technical solution, when the lap joint 4 overlaps with the support member 2, it pushes the buckle 9 toward one end of the inner side of the lap joint 4, so that the other end of the lap joint 4 moves out of the outer surface of the lap joint 4, and at the same time, the buckle 9 corresponds horizontally to the first slide 15, and the locking block 16 corresponds horizontally to the second slide 20. Then, when the extrusion block 5 is in the third state after the above process, the surface of the extrusion block 5 that fits the lap joint 4 can squeeze the buckle 9 and extend out of the outer surface of the lap joint 4, so that the buckle 9 is embedded in the first slide 15. The locking block 16 is pushed in and the locking block 16 is pressed by the protrusion 17 to squeeze the spring 19, so that the spring 19 is compressed and stores elastic potential energy, and the other end of the locking block 16 is embedded in the second slideway 20, thereby, one side of the end of the support member 2 is limited by the buckle 9 and the inner wall of the lap joint 4, and the other side of the end of the support member 2 is limited by the locking block 16 and the inner wall of the lap joint 4, thereby realizing the complete vertical limitation of the support member 2 and the lap joint 4, and further ensuring the stable connection between the support member 2 and the lap joint 4. In addition, after the support member 2 is removed from the beam body 1, it remains connected to the lap joint 4. At this time, the lap joint 4 is pulled toward the outside of the end of the support member 2, so that the buckle 9 slides in the first slide 15 and the locking block 16 slides in the second slide 20, so that the support member 2 and the lap joint 4 are separated smoothly. After separation, the elastic potential energy of the spring 19 is released, so that the locking block 16 is restored to the functional groove 10, and the two extrusion blocks 5 are also separated from each other, so that the elastic member 7 resumes free tilting, and the extrusion block 5 can easily restore to the first state.
