Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a supporting device for a prestressed concrete steel tube truss composite plate. Background Art

[0002] In the existing field of lightweight building material technology, prestressed concrete steel tube truss composite slabs are being used more and more widely in the construction industry. Prestressed concrete steel tube truss composite slabs are a structural form that combines prefabricated floor slabs and cast-in-place floor slabs. Prefabricated concrete thin plates are used as permanent formwork at the bottom, and cast-in-place concrete composite layers are poured on the upper part. The lower chord of the truss reinforcement can be used as the force-bearing reinforcement at the lower part of the composite slab, and the upper chord of the frame reinforcement can be used as a hanging point. The entire truss reinforcement plays a supporting role, enhancing the shear bearing capacity at the interface between the post-cast layer and the prefabricated bottom plate, and delaying the cracking of the component.

[0003] The patent with publication number CN115370188A discloses a support device for a prestressed concrete steel tube truss composite plate. The staff inserts the plug-in rod of the top support plate assembly into the limit hole of the connecting block, and the limit plug-in block cooperates with the fourth limit slot. Then, the connecting piece of the lifting assembly is plugged into the third limit slot on the connecting block, and then the connecting plug-in at the bottom of the lifting assembly is plugged into the axis. The lower half of the connecting plug-in cooperates with the second limit slot, and the upper half of the connecting plug-in is threadedly connected to the first sleeve. By changing the plug-in position of the limit plug-in block and the fourth limit slot, all the support plates are adjusted to the same direction, and then the support plates are fixed by tightening the bolts. The longitudinal cross-section of the support plate is "concave", and then the height of each support plate is adjusted to be consistent through several rotating wheel handles. In the process of adjusting the supporting structure, the height of each pallet is adjusted to be consistent by turning several wheel handles. Since it is difficult for the staff to directly judge whether the pallets have reached the same height visually, especially the adjacent pallets with opposite cross-sections, even if the staff observes and adjusts them many times, it is difficult to avoid slight height differences caused by visual errors or improper operation. Such differences may lead to uneven force on the pallets, which in turn causes safety hazards.

[0004] In view of this, how to reduce the time for adjusting multiple devices and reduce the current situation of potential safety hazards has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

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.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1The utility model provides a support device for a prestressed concrete steel tube truss composite plate, comprising: in order to maintain the stability of the base 1, three adjustable support components are arranged at the lower end of the base 1, which can be designed as four adjustable support components according to actual needs, and the base 1 is the foundation of the entire support device, and its design focuses on stability and load-bearing capacity. It is made of high-strength steel. In addition, a support sleeve 2 is arranged at the upper end of the base 1 in the vertical direction; the end of the support sleeve 2 away from the base 1 is slidably sleeved on the circumference of one end of the lifting rod 3, and the other end of the lifting rod 3 is detachably connected to the support plate 6, which is used to support the crossbeam (not shown in the figure). In order to support the crossbeam more stably, the support plate 6 The longitudinal cross-section is a "concave" shape; the driving assembly is arranged on the supporting sleeve 2, and its driving end and the handle 4 are detachably connected. The driving assembly is driven by the handle 4, and then the lifting rod 3 is driven to rise and fall, and different heights are lifted according to design requirements. The supporting sleeve 2 is made of high-quality steel, so that the supporting sleeve 2 has sufficient strength and wear resistance, and the smooth interior facilitates the sliding of the lifting rod 3; in addition, the two ends of the connecting rod 5 are respectively detachably connected to the driving assemblies of the adjacent devices, which are used to maintain the linkage of adjacent driving assemblies. The design of the connecting rod 5 realizes the linkage between multiple supporting devices, so that multiple devices can maintain the same height, thereby improving the stability of the overall structure.

[0029] Reference Figure 2 The connecting rod 5 includes a connecting sleeve 13 and a telescopic rod 14. One end of the connecting sleeve 13 is detachably connected to the driving assembly of one of the devices, and the other end of the telescopic rod 14 is detachably connected to the driving assembly of the other device. The other end of the connecting sleeve 13 is slidably sleeved on the circumference of one end of the telescopic rod 14. The side wall of the connecting sleeve 13 is provided with a first through hole, and the side wall of the telescopic rod 14 is provided with a plurality of second through holes. The first fastener 161 passes through the first through hole and is connected to any one of the second through holes. This design can adjust the length of the connecting rod 5 according to actual construction needs to adapt to the support requirements of composite plates of different widths.

[0030] Reference Figure 3The support sleeve 2 is fixedly connected to the dustproof box 7 at one end away from the base 1, and the driving assembly is cleverly hidden in the dustproof box 7. This design can protect the internal parts from dust and moisture erosion. The driving assembly includes a worm 9, a worm wheel 8 and a threaded sleeve 10. The threaded sleeve 10 is fixedly connected to the worm wheel 8. The threaded sleeve 10 and the dustproof box 7 are rotatably connected, and the threaded sleeve 10 is threadedly connected to the lifting rod 3. The worm wheel 8 is engaged with the worm 9 in the horizontal direction. The transmission of the worm wheel 8 and the worm 9 has a self-locking feature to ensure that the lifting rod 3 can stably maintain the set height when not subject to external force, and the two ends of the worm 9 rotate to penetrate the opposite side walls of the dustproof box 7 respectively.

Through the cooperation of the limiting grooves 11 and the limiting protrusions 12, this design not only ensures a firm connection, but also facilitates the rapid disassembly of the handle 4 and the connecting rod 5 when needed, thereby improving construction efficiency. The transverse cross-section of the limiting grooves 11 and the limiting protrusions 12 of this scheme is a "cross" shape.

[0032] Reference Figure 1 、 Figure 4 The lower end of the base 1 is fixedly connected to a vertical rod 18, and the support assembly includes a support leg 17. The base 1 is hinged to one end of the support leg 17. The support assembly also includes a sliding sleeve 19 and a sliding rod 20. The support leg 17, the sliding sleeve 19 and the sliding rod 20 together constitute an adjustable support assembly. One end of the sliding sleeve 19 is hinged to the middle of the support leg 17, and the other end of the sliding sleeve 19 is slidingly sleeved on the side of one end of the sliding rod 20. The other end of the sliding rod 20 is fixedly connected to the vertical rod 18. The sliding sleeve 19 is relatively provided with two guide grooves 21. One end of the sliding rod 20 Two guide blocks 22 are arranged at opposite ends, and the guide blocks 22 are slidably connected in the guide groove 21. The sliding sleeve 19 is provided with an external thread section. The side walls at both ends of the guide block 22 are in contact with the bolts 221. The two bolts 221 are threadedly connected to the external thread section. The external thread section and the guide groove 21 are of equal length. By adjusting the position of the two bolts and then moving the guide block 22, the distance between the ground supporting end of the support leg 17 and the vertical rod 18 can be adjusted. When the device is idle and transported, the support leg 17 can be completely retracted under the base 1. At this time, the device is more convenient for storage and transportation by the staff.

[0033] An end plate 23 is fixedly connected to the end of the vertical rod 18 away from the base 1. When the distance between the ground supporting end of the support leg 17 and the vertical rod 18 is adjusted to the maximum, the end plate 23 abuts against the ground. At this time, the end plate 23 protects the vertical rod 18 while also playing a supporting role, thereby enhancing the stability of the overall structure.

[0034] Reference Figure 5 A connecting block 24 is provided between the lifting rod 3 and the supporting plate 6, and the opposite side walls of the connecting block 24 are provided with limiting grooves 25, and the side walls of the vertical limiting groove 25 are provided with a third through hole and a fourth through hole. The third through hole and the fourth through hole are both detachably connected with a second fastener 162. A fixing rod 27 is provided at the upper end of the lifting rod 3, and a plug-in rod 26 is provided at the lower end of the supporting plate 6. One of the limiting grooves 25 and the fixing rod 27, and the other limiting groove 25 and the plug-in rod 26 are detachably connected by the second fastener 162. When the supporting plate 6 is damaged, it can be easily disassembled.

[0035] The first fastening member 161 and the second fastening member 162 are both bolts.

[0036] In this solution, four limiting plug-in blocks 28 are provided on the side wall of the plug-in rod 26. The four limiting plug-in blocks 28 are arranged in an equidistant circular array on the side wall of the plug-in rod 26. This array method allows the staff to coordinate the angle of the support plate 6 more conveniently before the device is raised or lowered. The limiting slot 25 detachably connected to the plug-in rod 26 is provided with four plug-in slots 29. The limiting plug-in blocks 28 and the plug-in slots 29 correspond to each other and are adapted to each other. The lower end of the plug-in slot 29 is away from the second fastener 162. This design enables the support plate 6 and the connecting block 24 to be tightly connected.

[0037] The working principle of the present invention is as follows: the staff places the base 1 on the drawing point, adjusts the bolt 221, and moves the position of the guide block 22 in the guide groove 21, thereby changing the inclination angle of the support leg 17 and the position of the ground support point. When the support leg 17 is fully extended, the end plate 23 abuts against the ground. At this time, the end plate 23 not only plays an additional supporting role, but also protects the vertical rod 18 from damage. After the adjustment is completed, the base 1 is in a horizontal state. The extension length of the telescopic rod 14 in the connecting sleeve 13 is adjusted according to the distance between the adjacent support devices, and the first fastener 161 is used to pass through the first through hole and the selected The second through hole is fixed to achieve precise adjustment of the length of the connecting rod 5, and then the second fastener 162 is passed through the third through hole and the fourth through hole to firmly install the lifting rod 3 and the support plate 6. At this time, the "concave" surfaces of the support plate 6 are set relative to each other, and the worm 9 is driven by the handle 4. The self-locking characteristics of the worm wheel 8 and the worm 9 are used to adjust the height of the lifting rod 3 so that the support plate 6 is at the composite plate support position required by the design. The multiple support devices are linked by the connecting rod 5 to ensure that the adjacent support devices can be synchronously lifted and lowered to the same height, thereby enhancing the stability and support efficiency of the overall structure.
