Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a precast component support structure. Background Technology

[0002] In modern industrial plant construction, prefabricated component assembly structures are often used to improve the efficiency of main structure construction, which can significantly shorten the construction period. Construction methods based on prefabricated components require the establishment of a scaffolding support system for beam and slab formwork erection.

[0003] The lower support is an adjustable component of the scaffolding support system, belonging to the category of screw rod accessories. It works in conjunction with cup-lock scaffolding to transfer supporting stress, and its height can be adjusted via the screw rod during use. During the use of the scaffolding support system, a sufficient height gap must be maintained between the lower support and the precast components to ensure that the lower support is lower than the precast components. After the precast components are hoisted into place, the lower support is raised using the screw rod adjustment until it provides support to the precast components. Because there are many lower supports in the scaffolding support system, the workload of raising and adjusting the lower supports is significant, resulting in low construction efficiency. Utility Model Content

[0004] To improve the low construction efficiency of adjusting the lower support in scaffolding support systems, this application provides a precast component support structure.

[0005] The precast component support structure provided in this application adopts the following technical solution: A precast component support structure includes a support plate, a screw rod, and a mounting base. The mounting base is used to install on the top end of a vertical steel pipe. One end of the screw rod is fixedly connected to the support plate, and the other end is threaded through and connected to the mounting base. A nut is threaded onto the screw rod, and the nut abuts against the mounting base. The support plate is hinged with a diagonal brace. The mounting base has a limiting member on the side near the support plate. The end of the diagonal brace away from the hinged end is used to support the angled area between the limiting member and the mounting base.

[0006] By adopting the above technical solution, when using the precast component support structure, it is installed at the top of the vertical steel pipe of the scaffold via a mounting base, and the horizontal steel pipe is supported by a support plate. Before tightening the nut, the support plate is manually raised to bring it closer to the precast component, and the diagonal brace abuts against the angled area between the limiting component and the mounting base, thus temporarily holding the support plate in a higher position. At the same time, the nut pre-installed on the screw rises with the screw, leaving the mounting plate, creating a height difference between the nut and the mounting base. At this time, there is no load between the nut and the screw, and the worker can easily rotate the nut manually, quickly spiraling it downwards to the position abutting the mounting base. Subsequently, a wrench is used to turn the nut, gradually applying a supporting force to the precast component through the horizontal steel pipe. In the above process, the support plate is first raised to a higher position by the support rod, thereby reducing the travel distance of the nut when rotating it with a wrench, which helps to improve construction efficiency.

[0007] Optionally, there are two diagonal braces and two limiting members. The two limiting members correspond to the two diagonal braces respectively, and the projection of the hinged ends of the two diagonal braces on the surface of the mounting base is located between the two limiting members.

[0008] By adopting the above technical solution, since the projection of the hinged ends of the two diagonal braces on the surface of the mounting base is located between the two limiting members, when the two diagonal braces are in the support state, the two diagonal braces gradually tilt towards each other from bottom to top, making the support state of the two support rods more stable.

[0009] Optionally, the diagonal brace is a lead screw and threaded sleeve assembly.

[0010] By adopting the above technical solution, using the screw and threaded sleeve assembly as the diagonal brace, the actual length of the diagonal brace can be adjusted as needed.

[0011] Optionally, two screws are provided, one of which serves as the main support screw and the other as the auxiliary support screw. The main support screw passes through the mounting base and is used to insert into the vertical steel pipe.

[0012] By adopting the above technical solution and setting two screws, the supporting effect on the precast components can be increased. The main support screw is inserted into the vertical steel pipe, and the supporting effect is relatively reliable.

[0013] Optionally, the two screws have opposite thread directions, and one end of the nut is provided with a gear, with the two gears meshing with each other.

[0014] By adopting the above technical solution, the gears on the two nuts mesh with each other, and while adjusting one nut, the other nut can be rotated at the same time, which helps to improve construction efficiency.

[0015] Optionally, the support screw includes a smooth rod and an external threaded sleeve. The smooth rod is fixedly connected to the support plate, the nut is threadedly connected to the external threaded sleeve, the external threaded sleeve is sleeved and connected to the smooth rod, and the external threaded sleeve and the smooth rod are both inserted with a pin. The external threaded sleeve has a first pin hole for the pin to be inserted, and the smooth rod has a second pin hole for the pin to be inserted. There are multiple second pin holes, which are spaced apart along the axial direction.

[0016] By adopting the above technical solution, after the diagonal brace lifts the support plate upward, the pin is removed from the second pin hole of the smooth rod. Then, the external threaded sleeve is moved downward along the smooth rod a certain distance until the first pin hole is aligned with the new second pin hole. The pin is then used to reconnect the external threaded sleeve and the smooth rod, so that the nut can simultaneously drive the external threaded sleeve and the smooth rod to move upward.

[0017] Optionally, the pin is gradually tilted towards the support plate in a direction away from the light rod.

[0018] By adopting the above technical solution, when the screw is in use, the pin gradually tilts upwards in the direction away from the smooth rod, making it less likely for the pin to loosen and fall off on its own.

[0019] Optionally, the mounting base includes a base plate and two positioning cylinders. The positioning cylinders are vertically fixedly connected to the base plate. The base plate has two through holes for the screw to pass through, and the two through holes are respectively connected to the positioning cylinders. Either of the two positioning cylinders is used to be sleeved on the vertical steel pipe of the scaffold.

[0020] By adopting the above technical solution, the positioning cylinder can ensure the stability of the installation state of the mounting base.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When using precast component support structures, the support plate is first raised to a higher position by the support rod, thereby reducing the stroke of the nut when using a wrench, which helps to improve construction efficiency.

[0022] 2. Since the projection of the hinged ends of the two diagonal braces onto the surface of the mounting base is located between the two limiting members, when the two diagonal braces are in the supporting state, the two diagonal braces gradually tilt towards each other from bottom to top, making the supporting state of the two support rods relatively stable.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] Example 1 This application discloses a prefabricated component support structure. (Refer to...) Figure 1 and Figure 2 The precast component support structure includes a support plate 1, a screw rod 2, and a mounting base 3. The mounting base 3 includes a base plate 31 and a positioning cylinder 32. The positioning cylinder 32 is vertically fixedly connected to the base plate 31. A reinforcing rib 33 is connected between the outer circumference of the positioning cylinder 32 and the base plate 31. The positioning cylinder 32 is located on the side of the base plate 31 away from the support plate 1. The positioning cylinder 32 is used to be sleeved and installed on the top of the vertical steel pipe 6. The base plate 31 has a through hole 311 for the screw rod 2 to pass through. The through hole 311 is smaller than the inner diameter of the vertical steel pipe 6. One end of the screw rod 2 is fixedly connected to the support plate 1. The other end of the screw rod 2 passes through the through hole 311 and is used to be inserted into the vertical steel pipe 6. The screw rod 2 is threadedly connected to a nut 4. The nut 4 abuts against the side of the base plate 31 away from the positioning cylinder 32.

[0031] In this embodiment, the mounting base 3 is a metal part, which can be manufactured by welding or machining. The limiting member 34 is a metal block, which can be fixed to the base plate 31 by welding or by using threaded fasteners.

[0032] The support plate 1 is hinged with two diagonal braces 5, which are located on both sides of the screw 2. The seat plate 31 is fixedly provided with two limiting members 34 on the side near the support plate 1. The two limiting members 34 are located on both sides of the screw 2. The distance between the two limiting members 34 is greater than the distance between the hinged ends of the two diagonal braces 5. The projection of the hinged ends of the two diagonal braces 5 on the surface of the mounting base 3 is located between the two limiting members 34. The end of the diagonal brace 5 away from the hinged end is used to support the angled area between the limiting member 34 and the mounting base 3.

[0033] The implementation principle of a precast component support structure according to an embodiment of this application is as follows: When using the precast component support structure, it is installed at the top of the vertical steel pipe 6 of the scaffold via the mounting base 3, and the horizontal steel pipe is supported by the support plate 1. Before tightening the nut 4, the support plate 1 is manually raised to bring it closer to the precast component, and the diagonal brace 5 abuts against the angle area between the limiting member 34 and the mounting base 3, thereby temporarily holding the support plate 1 in a higher position. At the same time, the nut 4 pre-installed on the screw 2 rises away from the mounting plate with the screw 2, creating a height difference between the nut 4 and the mounting base 3. At this time, there is no load between the nut 4 and the screw 2, and the worker can easily rotate the nut 4 manually to quickly spiral it downwards to the position abutting the mounting base 3. Subsequently, a wrench is used to turn the nut 4, so that the nut 4 and the screw 2 gradually apply a supporting force to the precast component through the horizontal steel pipe. After tightening the nut 4 with a wrench, the diagonal brace 5 rises upwards with the screw 2, and the support rod is released from the supporting state. In the above process, the support plate 1 is first raised to a higher position by the support rod, thereby reducing the stroke of the nut 4 when rotating it with a wrench, which helps to improve construction efficiency.

[0034] Example 2 Reference Figure 3 The difference between this embodiment and Embodiment 1 is that, in this embodiment, there are two screws 2. One of the screws 2 is used to connect with the vertical steel pipe 6. The screw 2 used to connect with the vertical steel pipe 6 serves as the main support screw 201, and the other serves as the auxiliary support screw 202. The base plate 31 has two through holes 311, and there are two positioning cylinders 32, each corresponding to and connected to one of the through holes 311.

[0035] In this embodiment, the threads of the two screws 2 are turned in opposite directions, and one end of the nut 4 is provided with a gear 41, and the two gears 41 mesh with each other.

[0036] This embodiment enhances the support for precast components by using two screws 2. The main support screw 201 is inserted into the vertical steel pipe 6, providing reliable support. The gears 41 on the two nuts 4 mesh with each other, allowing the other nut 4 to rotate simultaneously during the adjustment of one nut 4, thus improving construction efficiency.

[0037] Example 3 Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that the support screw 2 includes a smooth rod 21 and an external threaded sleeve 22. The smooth rod 21 is fixedly connected to the support plate 1, and the nut 4 is threadedly connected to the external threaded sleeve 22. The external threaded sleeve 22 is sleeved and connected to the smooth rod 21. The external threaded sleeve 22 and the smooth rod 21 are both inserted with a pin 23. The external threaded sleeve 22 has a first pin hole 221 for the pin 23 to be inserted, and the smooth rod 21 has a second pin hole 211 for the pin 23 to be inserted. There are multiple second pin holes 211, which are spaced apart along the axial direction. The second pin holes 211 are set as oblique holes, and the pin 23 gradually tilts towards the support plate 1 in the direction away from the smooth rod 21.

[0038] In this embodiment, the support screw 2 is threadedly engaged with the nut 4 via an external threaded sleeve 22, and the external threaded sleeve 22 and the smooth rod 21 are detachably connected via a pin 23. When the diagonal brace 5 lifts the support plate 1 upward, the pin 23 is removed from the second pin hole 211 of the smooth rod 21. Then, the external threaded sleeve 22 is moved downward along the smooth rod 21 a certain distance until the first pin hole 221 aligns with the new second pin hole 211. The pin 23 is then used to reconnect the external threaded sleeve 22 and the smooth rod 21, so that the nut 4 can simultaneously drive the external threaded sleeve 22 and the smooth rod 21 upward.

[0039] Another difference between this embodiment and Embodiment 1 is that the diagonal brace 5 is a screw threaded sleeve assembly. Using the screw threaded sleeve assembly as the diagonal brace 5 allows the actual length of the diagonal brace 5 to be adjusted as needed. Moreover, the screw threaded sleeve assembly can also provide auxiliary support after being adjusted and extended during use.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
