Description

Technical Field

[0001] The utility model relates to the technical field of composite plate installation, in particular to a composite plate reinforcement positioning device. Background Art

[0002] Composite floor slabs are assembled monolithic structures composed of precast panels and cast-in-place reinforced concrete layers. The precast panels serve as both a structural component and a permanent formwork for the cast-in-place reinforced concrete layer, which can accommodate horizontal equipment and pipelines. Composite floor slabs offer excellent integrity and high rigidity, saving on formwork. Their smooth upper and lower surfaces facilitate finishing, making them suitable for high-rise buildings and large-span structures requiring high rigidity.

[0003] During the installation of prefabricated composite slabs, wire is required to securely connect the steel bars of the prefabricated composite slabs to the steel bars of the building itself, thereby ensuring that the prefabricated composite slabs will not shift or misalign during the pouring process. However, to secure the steel bars with wire, it is necessary to first cut the wire to an appropriate length and then use a tool to screw the wire to the surfaces of the two steel bars. The entire operation is time-consuming and affects construction efficiency. Therefore, the present invention proposes a steel bar positioning device for composite slabs. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a composite plate reinforcement positioning device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a composite plate steel bar positioning device, comprising a U-shaped rod, the surface of the U-shaped rod is slidably connected to an extrusion assembly, both sides of the U-shaped rod are located below the extrusion assembly and are penetrated and threadedly connected with extrusion screws, the top of the U-shaped rod is open, and a cross plate is provided at the top of the U-shaped rod, an adjusting screw for driving the extrusion assembly to move is installed in the middle of the cross plate, and fixing components for fixing the cross plate are provided on the top of both ends of the U-shaped rod.

[0006] Furthermore, one end of the extrusion screw outside the U-shaped rod is fixedly connected to a first knob.

[0007] Furthermore, the extrusion assembly includes two sliding sleeves slidably connected to the two end surfaces of the U-shaped rod, a cross bar is fixedly connected between the two sliding sleeves, a vertical rod is fixed to the middle of the lower surface of the cross bar, and an extrusion plate is fixedly connected to the bottom end of the vertical rod.

[0008] Furthermore, the bottom end of the adjusting screw is rotatably connected to the upper surface of the cross bar via a bearing, and the top end of the adjusting screw is fixedly connected to a second knob.

[0009] Furthermore, the fixing assembly includes an insert block fixed to the top end of the U-shaped rod, and the insert block is square.

A spring is fixedly connected to the inner side wall of the groove, and a latch is fixedly connected to the other end of the spring. The latch is connected to the upper surface of the horizontal plate away from the end of the spring.

[0010] Furthermore, the fixing assembly includes a connecting screw fixed to the top of the U-shaped rod, and circular holes for passing the connecting screw are opened at both ends of the horizontal plate.

[0011] Beneficial effects of the utility model:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-Figure 3 As shown, it relates to a composite plate steel bar positioning device, including a U-shaped rod 1, an extrusion component 2 is slidably connected to the surface of the U-shaped rod 1, and extrusion screws 3 are passed through and threadedly connected below the extrusion component 2 on both sides of the U-shaped rod 1. The top of the U-shaped rod 1 is open, and a cross plate 4 is provided at the top of the U-shaped rod 1. An adjusting screw 5 for driving the extrusion component 2 to move is installed in the middle of the cross plate 4, and a fixing component 7 for fixing the cross plate 4 is provided on the top of each end of the U-shaped rod 1.

[0023] One end of the extrusion screw 3 outside the U-shaped rod 1 is fixedly connected to a first knob 31 .

[0024] After the U-shaped rod 1 is clamped on the surface of the composite plate steel bar 9 and the building steel bar 10, the first knob 31 can be rotated to drive the extrusion screw 3 to squeeze the composite plate steel bar 9 or the building steel bar 10, thereby achieving further fixation of the device.

[0025] The extrusion assembly 2 includes two sliding sleeves 21 that are slidably connected to the surfaces of both ends of the U-shaped rod 1. A cross bar 22 is fixedly connected between the two sliding sleeves 21. A vertical rod 23 is fixed to the middle of the lower surface of the cross bar 22, and an extrusion plate 24 is fixedly connected to the bottom end of the vertical rod 23.

[0026] The crossbar 22 of the extrusion assembly 2 moves toward the composite plate reinforcement 9 and the construction reinforcement 10 , so that the extrusion plate 24 can extrusion-connect the composite plate reinforcement 9 and the construction reinforcement 10 together.

[0027] The bottom end of the adjusting screw 5 is rotatably connected to the upper surface of the cross bar 22 via a bearing, and the top end of the adjusting screw 5 is fixedly connected to a second knob 6 .

[0028] The crossbar 22 can be driven to move upward or downward by rotating the adjusting screw 5 .

[0029] In this embodiment, the fixing assembly 7 includes an insert block 71 fixed to the top end of the U-shaped rod 1, and the insert block 71 is square. Square holes 41 for passing through the insert block 71 are provided at both ends of the horizontal plate 4. A groove 72 is provided on the side wall of one end of the insert block 71 passing through the square hole 41. A spring 73 is fixedly connected to the inner side wall of the groove 72, and a latch tooth 74 is fixedly connected to the other end of the spring 73. The latch tooth 74 is latched on the upper surface of the horizontal plate 4 away from the end of the spring 73.

[0030] When the cross plate 4 needs to be fixed to the top of the U-shaped rod 1, the insert block 71 is passed through the square holes 41 at both ends of the cross plate 4. When the latch teeth 74 pass through the square holes 41, the spring 73 will push the latch teeth 74 out of the groove 72, so that the latch teeth 74 are stuck on the surface of the cross plate 4, thereby realizing a quick fixed connection between the cross plate 4 and the U-shaped rod 1.

[0031] Example 2

[0032] like Figure 4 As shown, the fixing assembly 7 includes a connecting screw 75 fixed to the top of the U-shaped rod 1, and circular holes 42 for passing the connecting screw 75 are opened at both ends of the cross plate 4. The top of the connecting screw 75 passes through the surface of the circular hole 42 and is rotatably connected to an internal threaded cap 76.

[0033] When the cross plate 4 needs to be fixed to the top of the U-shaped rod 1, the connecting screw 75 at the top of the U-shaped rod 1 is passed through the circular hole 42 on the cross plate 4, and then the internal threaded cap 76 is screwed on the surface of the connecting screw 75, thereby achieving a fixed connection between the cross plate 4 and the U-shaped rod 1.

[0034] Working principle: Figure 1 After the prefabricated composite slab 8 is placed, the composite slab steel bars 9 will overlap with the construction steel bars 10. At this time, first clamp the U-shaped rod 1 on the surface of the composite slab steel bars 9 and the construction steel bars 10, then fix the cross plate 4 to the top of the U-shaped rod 1 through the fixing assembly 7, then rotate the adjusting screw 5 in the middle of the cross plate 4, and use the adjusting screw 5 to drive the extrusion assembly 2 to move, so that the extrusion plate 24 extrude the composite slab steel bars 9 and the construction steel bars 10, and finally rotate the extrusion screws 3 on both sides of the U-shaped rod 1 to further fix the composite slab steel bars 9 and the construction steel bars 10.
