Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a non-dismantling composite floor slab reinforcement device. Background Technology

[0002] Precast unsupported steel truss floor slabs are truss floor slabs formed by combining cement boards for HY concrete engineering, C-shaped steel, steel trusses, load-bearing steel bars, etc. Precast unsupported steel truss floor slabs have good integrity, smooth surface, light weight, and are easy to transport and install, and are suitable for residential and public buildings.

[0003] Precast concrete slabs are hoisted to the top of the floor for installation. However, gaps typically exist between adjacent slabs, which can cause concrete leakage and reduce the effectiveness of the installation. Currently, there is a lack of reinforcement devices to address this issue. Utility Model Content

[0004] In view of this, the present invention provides a non-dismantling composite floor slab reinforcement device to solve the problem that the gaps between composite floor slabs can easily lead to leakage of poured concrete.

[0005] This utility model provides a non-dismantling composite floor slab reinforcement device, which is installed on the main bodies of two adjacent composite slabs, including:

[0006] The T-shaped plate is snapped between two composite plate bodies and extends along the length of the gap between the two composite plate bodies.

[0007] Fastening components are installed between the T-shaped plate and the two composite plate bodies;

[0008] The fastening assembly is adapted to adjust the distance between the T-shaped plate and the composite plate body, so that the T-shaped plate and the composite plate body are sealed together.

[0009] In this application, the gap between the T-shaped plate and the composite plate body is reduced by fastening components until the T-shaped plate and the composite plate body are sealed, thus sealing the gap between the two composite plate bodies and preventing concrete from leaking from the gap during pouring.

[0010] In one alternative implementation, the fastening assembly includes:

[0011] The reinforcing bars are fixedly installed on the composite slab body;

[0012] The connecting rod is fixedly connected to the T-shaped plate;

[0013] A locking element, disposed between the reinforcing bar and the connecting rod, is suitable for adjusting the spacing between the reinforcing bar and the connecting rod.

[0014] In this application, the spacing between the T-shaped plate and the main body of the composite plate can be adjusted by adjusting the spacing of the reinforcing bars and connecting rods.

[0015] In one alternative embodiment, the connecting rod is located above the T-shaped plate and is connected to the T-shaped plate via a support post.

[0016] In this application, the force on the T-shaped plate can be made more uniform, preventing the T-shaped plate from tilting and causing the T-shaped plate and the composite plate body to fail to form a seal.

[0017] In one alternative embodiment, the locking element includes:

[0018] A threaded pin ring rod, wherein the ring end of the threaded pin ring rod is engaged with a connecting rod;

[0019] A threaded pin hook, wherein the hook end of the threaded pin hook engages with a reinforcing bar;

[0020] The adjusting rod is screwed to the threaded end of the threaded pin ring rod and the threaded end of the threaded pin hook respectively, and the screwing directions are opposite.

[0021] In this application, the distance between the threaded pin ring rod and the threaded pin hook can be reduced by rotating the adjusting rod, thereby pulling the T-shaped plate and the composite plate body closer to each other.

[0022] In one optional embodiment, the adjusting rod has a threaded hole on its inner side, and the threaded end of the threaded pin ring rod and the threaded end of the threaded pin hook are both screwed into the threaded hole, with the threads of the threaded end of the threaded pin ring rod and the threaded end of the threaded pin hook having opposite directions of rotation.

[0023] In one alternative embodiment, a retaining ring is provided on the connecting rod, and the ring end of the threaded pin ring is engaged with the retaining ring.

[0024] In this application, the retaining ring prevents the ring end of the threaded pin ring rod from sliding along the length of the connecting rod.

[0025] In one alternative embodiment, the reinforcing bars are connected to the composite slab body via a bracket.

[0026] In this application, the bracket can prevent the threaded pin hook from rubbing against the surface of the composite plate body, thereby preventing wear on the surface of the composite plate body.

[0027] In one alternative embodiment, a rubber strip is provided on the side of the T-shaped plate facing the main body of the composite plate.

[0028] In this application, when the T-shaped plate and the composite plate body are close to each other, the rubber strip can be squeezed to increase the sealing effect at the gap. Furthermore, the composite plate body will expand and contract due to temperature, humidity and chemical changes, and the rubber strip can reserve enough space for expansion and contraction to alleviate the shrinkage caused by stress at the joint and improve the performance.

[0029] In one optional embodiment, sliders are provided on both sides of the T-shaped plate, and the surfaces of the two composite plate bodies are provided with grooves that are adapted to the sliders, and the sliders are slidably disposed in the grooves.

[0030] In this application, the connection between the T-shaped plate and the composite plate body can be limited by the slider and the groove, so as to avoid displacement of the connection between two adjacent composite plate bodies. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Precast unsupported steel truss floor slabs are assembled precast unsupported steel truss floor slabs formed by combining cement boards for HY concrete engineering, C-shaped steel, steel trusses, load-bearing steel bars, etc. Precast unsupported steel truss floor slabs have good integrity, flat surface, light weight, and are easy to transport and install, and are suitable for residential and public buildings.

[0040] The non-removable composite floor slabs are hoisted to the top of the floor to achieve the purpose of laying. However, there will be gaps between two adjacent composite floor slabs. The joints of the composite floor slabs are weak points in terms of load-bearing capacity and are prone to misalignment, resulting in poor overall integrity of the composite floor slabs. In addition, it is easy for poured concrete to leak from the gaps, reducing the effectiveness of the device. Therefore, we have proposed a non-removable composite floor slab reinforcement device to solve the above-mentioned problems.

[0041] As attached Figures 1 to 4 As shown, this utility model provides a non-dismantling composite floor slab reinforcement device, which is installed on two adjacent composite slab bodies 1, and includes:

[0042] T-shaped plate 2 is snapped between two composite plate bodies 1 and extends along the length of the gap between the two composite plate bodies 1; the top and bottom surfaces of the T-shaped plate 2 abut against the top surfaces of the two composite plate bodies 1.

[0043] A fastening assembly is provided between the T-shaped plate 2 and the two composite plate bodies 1;

[0044] The fastening assembly is adapted to adjust the distance between the T-shaped plate 2 and the composite plate body 1, thereby sealing the gap between the T-shaped plate 2 and the composite plate body 1. It can be considered that there are two sets of fastening assemblies, respectively disposed between the T-shaped plate 2 and the two composite plate bodies 1. The fastening assembly can reduce the distance between the T-shaped plate 2 and the composite plate body 1, thereby sealing the gap between the two composite plate bodies 1.

[0045] In this application, the gap between the T-shaped plate 2 and the composite plate body 1 is reduced by fastening components until the T-shaped plate 2 and the composite plate body 1 are sealed, thus sealing the gap between the two composite plate bodies 1, so that the poured concrete will not leak from the gap during pouring.

[0046] Specifically, the fastening assembly may include a wedge block assembly and a locking mechanism. The wedge block assembly includes: multiple sets of wedge grooves symmetrically arranged on both sides of the T-shaped plate 2, with a pair of slidable wedge blocks installed in each groove. The wedge blocks have an inclination angle of 15°-30°, anti-slip teeth at the bottom, and a spring connecting the top to the inner wall of the wedge groove to provide pre-tightening force. The locking mechanism includes: a locking groove on the side of the composite plate body 1 near the T-shaped plate 2, with a rotatable locking rod installed in the groove. The end of the locking rod is designed as a hook, matching the groove of the wedge block to lock its position. The operation procedure is as follows: during installation, the T-shaped plate 2 is inserted between the two sets of composite plate bodies 1, and the wedge blocks are manually pushed to slide along the wedge grooves towards the composite plate body 1. After the inclination of the wedge block contacts the composite plate body 1, the spring is compressed, and the pushing continues until the rubber band 12 is fully compressed. Rotate the locking lever to hook it into the groove of the wedge block, fix the position of the wedge block, and prevent it from springing back.

[0047] In one alternative implementation, as shown in the appendix Figures 2 to 4 As shown, the fastening assembly includes:

[0048] The reinforcing bars 3 are fixedly installed on the composite slab body 1; there can be multiple sets of reinforcing bars 3, which can be parallel to the extension direction of the T-shaped plate 2.

[0049] Connecting rod 4 is fixedly connected to the T-shaped plate 2; the connecting rod 4 can be positioned directly above the T-shaped plate 2.

[0050] A locking element 5 is disposed between the reinforcing bar 3 and the connecting rod 4, and is suitable for adjusting the distance between the reinforcing bar 3 and the connecting rod 4. Multiple sets of locking elements 5 may be connected between the reinforcing bar 3 and the connecting rod 4.

[0051] In this application, the distance between the T-shaped plate 2 and the composite plate body 1 can be adjusted by adjusting the spacing of the reinforcing bar 3 and the connecting rod 4.

[0052] Specifically, the locking component 5 may include a hydraulic cylinder assembly and a sealing and limiting assembly. The hydraulic cylinder assembly includes a bidirectional micro hydraulic cylinder installed between the connecting rod 4 and the reinforcing bar 3, with both ends of the hydraulic cylinder hinged to the connecting rod 4 and the reinforcing bar 3 respectively. The hydraulic cylinder is driven by a manual pump or pneumatic pressure, and the internal piston pushes hydraulic oil to achieve extension and retraction. The sealing and limiting assembly includes a pressure sensor built into the hydraulic cylinder, which provides real-time feedback of pressure data to an external display instrument to ensure that the rubber belt 12 is uniformly compressed. A mechanical lock is installed at the end of the piston rod, and the piston position is manually locked after adjustment to prevent pressure release and retraction. Operation procedure: Pressurization is performed by a manual pump, and the hydraulic cylinder pushes the connecting rod 4 towards the reinforcing bar 3, compressing the rubber belt 12. The pressure value on the instrument is observed, and pressurization is stopped after reaching a preset threshold, and the mechanical lock is activated to fix the piston position. When pressure is released, the lock is unlocked, and the hydraulic cylinder automatically resets.

[0053] In one alternative implementation, as shown in the appendix Figure 1 The connecting rod 4 is located above the T-shaped plate 2 and is connected to the T-shaped plate 2 via a support column 6. Multiple support columns 6 can be connected between the connecting rod 4 and the T-shaped plate 2.

[0054] In this application, the force on the T-shaped plate 2 can be made more uniform, preventing the T-shaped plate 2 from tilting and causing the T-shaped plate 2 and the composite plate body 1 to fail to form a seal.

[0055] In one alternative implementation, as shown in the appendix Figure 4 As shown, the locking member 5 includes:

[0056] The threaded pin ring rod 7 has a ring end that engages with the connecting rod 4; the threaded pin ring rod 7 includes a ring end and a threaded rod end.

[0057] A threaded pin hook 8, the hook end of which engages with the reinforcing bar 3; the threaded pin hook 8 includes a hook end and a threaded rod end.

[0058] Adjusting rod 9 is screwed to the threaded end of threaded pin ring rod 7 and the threaded end of threaded pin hook 8 respectively, and the screwing directions are opposite.

[0059] Among them, the threaded pin ring rod 7 and the threaded pin hook 8 are located on both sides of the adjusting rod 9, and the direction of the line connecting the threaded pin ring rod 7, the threaded pin hook 8 and the adjusting rod 9 is the direction from the reinforcing bar 3 to the connecting rod 4.

[0060] In this application, the distance between the threaded pin ring rod 7 and the threaded pin hook 8 can be reduced by rotating the adjusting rod 9, thereby pulling the T-shaped plate 2 and the composite plate body 1 closer to each other.

[0061] In one optional embodiment, the adjusting rod 9 has a threaded hole on its inner side, and the threaded end of the threaded pin ring rod 7 and the threaded end of the threaded pin hook 8 are both screwed into the threaded hole, with the threads of the threaded end of the threaded pin ring rod 7 and the threaded end of the threaded pin hook 8 having opposite directions of rotation.

[0062] In one optional embodiment, a fixing ring 10 is provided on the connecting rod 4, and the ring end of the threaded pin ring 7 is fastened to the fixing ring 10. Multiple sets of fixing rings 10 may be arranged symmetrically on both sides of the connecting rod 4. The ring end of the threaded pin ring 7 is fastened to the fixing ring 10. The threaded pin hooks 8 on both sides of the connecting rod 4 are respectively fastened to the steel bars 3 of the two sets of composite plate bodies 1 that are close to each other.

[0063] In this application, the retaining ring 10 prevents the ring end of the threaded pin ring rod 7 from sliding along the length direction of the connecting rod 4.

[0064] In one optional embodiment, the reinforcing bar 3 is connected to the composite slab body 1 via a bracket 11. Multiple brackets 11 may be used.

[0065] In this application, the bracket 11 can prevent the threaded pin hook 8 from rubbing against the surface of the composite plate body 1, thereby preventing wear on the surface of the composite plate body 1.

[0066] In one optional embodiment, a rubber strip 12 is provided on the side of the T-shaped plate 2 facing the composite plate body 1. The rubber strip 12 is provided on both sides of the T-shaped plate 2.

[0067] In this application, when the T-shaped plate 2 and the composite plate body 1 are close to each other, the rubber strip 12 can be squeezed to increase the sealing effect at the gap. Furthermore, the composite plate body 1 will expand and contract due to temperature, humidity and chemical changes. The rubber strip 12 can reserve enough space for expansion and contraction to alleviate the shrinkage caused by stress at the joint and improve the performance.

[0068] In one optional embodiment, sliders 13 are respectively provided on both sides of the T-shaped plate 2, and the surfaces of the two composite plate bodies 1 are provided with grooves 14 adapted to the sliders 13, and the sliders 13 are slidably disposed in the grooves 14. There can be multiple sets of sliders 13.

[0069] In this application, the connection between the T-shaped plate 2 and the composite plate body 1 can be limited by the slider 13 and the groove 14, so as to avoid the displacement of the connection between two adjacent composite plate bodies 1.

[0070] In one alternative embodiment, the connecting rod 4 and the reinforcing bar 3 are flush.

[0071] In this application, the T-shaped plate 2 can be prevented from tilting.

[0072] When in use, the composite slab body 1 is first hoisted to the top of the floor using hoisting equipment (not shown in the figure). When laying a set of composite slab bodies 1, the first composite slab body 1 is first fixed and locked to the crossbeam (not shown in the figure).

[0073] Then, the T-shaped plate 2 is inserted between the two composite plate bodies 1, so that the inner wall of the top surface of the T-shaped plate 2 is in contact with the top of the two composite plate bodies 1, while the rubber strip 12 is located between the composite plate body 1 and the T-shaped plate 2.

[0074] While the T-shaped plate 2 is placed, multiple sets of sliders 13 on the T-shaped plate 2 are respectively locked onto the grooves 14 opened on the two composite plate bodies 1. Through the setting of sliders 13 and grooves 14, the connection between the T-shaped plate 2 and the two composite plate bodies 1 can be limited, thus preventing the two sets of composite plate bodies 1 from shifting.

[0075] Then, the threaded pin hooks 8 on both sides of the connecting rod 4 are respectively fastened to the steel bars 3 of the two composite plate bodies 1 that are close to each other. Then, the adjusting rod 9 is rotated. Since the two ends of the adjusting rod 9 are respectively threadedly connected to the threaded pin ring rod 7 and the threaded pin hook 8, and the threaded pin ring rod 7 and the threaded pin hook 8 have opposite thread teeth structure design, when one set of adjusting rods 9 is rotated, the threaded pin ring rod 7 and the threaded pin hook 8 can be driven to move towards each other. At this time, the threaded pin hook 8 will pull the steel bar 3 to move towards the connecting rod 4, thereby driving the composite plate body 1 on one side to move towards the T-shaped plate 2, and squeezing the rubber strip 12 on one side.

[0076] At the same time, rotating another set of adjusting rods 9 will also drive the threaded pin ring rod 7 and the threaded pin hook 8 to move closer to each other. Since the first composite plate body 1 is fixed on the crossbeam, the T-shaped plate 2 will move closer to the composite plate body 1, causing the rubber strip 12 on the other side of the composite plate body 1 and the T-shaped plate 2 to be squeezed.

[0077] Through the above operations, the tightness between the two composite slab bodies 1 can be increased. At the same time, the slider 13 on the T-shaped plate 2 is fastened to the slide groove 14, preventing the two sets of composite slab bodies 1 from shifting relative to each other. Meanwhile, the connecting rod 4 is connected to the steel bar 3 on the composite slab body 1 through the locking part, thereby realizing the splicing of the two composite slab bodies 1. Through this operation, multiple composite slab bodies 1 are spliced ​​together by continuous laying, which improves the overall strength. Thus, under the connection of the steel bar 3, the T-shaped plate 2 can support and strengthen the weak load-bearing parts at the joint of the composite slab body 1 to avoid damage. The connection parts of the composite slab body 1 are reinforced, making the composite slab body 1 more integral and with higher load-bearing capacity.

[0078] Furthermore, the rubber band 12 increases the sealing performance of the composite slab body 1 and the T-shaped plate 2 when they are pressed together, thereby achieving a sealing effect at the connection between the two sets of composite slab bodies 1. This reduces the risk of concrete seeping out from the gaps. At the same time, the rubber band 12 will deform under compression, thus realizing the expansion and contraction gap between the composite slab body 1 and the T-shaped plate 2. The composite slab body 1 expands and contracts due to temperature, humidity and chemical changes, and this allows for sufficient expansion and contraction space, thereby alleviating the shrinkage caused by stress at the joint and improving the effectiveness of the device.

[0079] This application solves the problem that gaps exist between two adjacent composite floor slabs, and that the joints of the composite floor slabs are weak points in terms of load-bearing capacity, making them prone to misalignment, resulting in poor overall integrity of the composite floor slabs. Furthermore, it can easily lead to leakage of poured concrete through the gaps, reducing the effectiveness of the device.

[0080] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
