Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a formwork for an elevator shaft shear wall. Background Technology

[0002] Elevator shaft shear walls refer to the walls inside elevator shafts. They are constructed of reinforced concrete and have high rigidity and load-bearing capacity.

[0003] Traditional formwork is mainly assembled by welding or connecting components such as channel steel, steel pipes, steel plates, and bolts. In contrast, a factory-customized integrated steel platform system is used for on-site installation. The design and cutting of materials are based on the actual dimensions of the elevator shaft, followed by welding and assembly. After assembly, a tower crane is used to lift and install the auxiliary operating platform. After installation, an acceptance test is conducted, and once approved, the platform is put into use for on-site construction. Once the next floor is completed and the formwork is ready for removal, the tower crane is used again to lift the operating platform for the next floor's construction. The process is simple and convenient.

[0004] However, the existing templates are all one-piece designs, assembled by welding, which is inconvenient for transportation and installation, and their practicality needs to be improved.

[0005] Therefore, we propose a new type of elevator shaft shear wall formwork. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that existing templates are all one-piece and assembled by welding, which is inconvenient for transportation and installation, and their practicality needs to be improved.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an elevator shaft shear wall formwork, comprising a formwork body, a portable folding support assembly connected to the center of the bottom rear end of the formwork body, the portable folding support assembly comprising a first rotating shaft, a main support plate connected to the surface of the first rotating shaft, a groove formed on one side surface of the main support plate, a slot formed on the side of the main support plate near the first rotating shaft, a magnetic block connected to the rear end of the main support plate, a connecting rod rotatably connected within the groove, a telescopic rod inserted into the inside of the connecting rod, a threaded hole formed on one side surface of the telescopic rod, a first bolt disposed inside the threaded hole, a rotating block connected to the front end of the telescopic rod, and holes formed on both sides of the rotating block.

[0008] Furthermore, a second bolt is inserted into the interior of each of the two sets of holes, and the second bolt forms a threaded connection with the template body after passing through the hole.

[0009] Furthermore, a magnet is fitted into the position where the template body matches the magnetic block, and the magnet and the magnetic block form a magnetic connection.

[0010] Furthermore, the outer surface of the telescopic rod is in contact with the inner wall of the connecting rod, and a sliding connection is formed between the telescopic rod and the connecting rod.

[0011] Furthermore, the size of the slot matches the size of the rotating block, and the rotating block and the slot form a snap-fit ​​connection.

[0012] Furthermore, splicing components are connected to the outer surfaces of both sides of the template body. The splicing components include slides and sliders, which are respectively connected to both sides of the template body.

[0013] Furthermore, the inner wall of the slide is provided with a groove.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when supporting the formwork for the shear wall of the elevator shaft, the main support plate can be folded open through the first pivot, and the telescopic rod can be used to support the main body of the formwork. This avoids the problem that the existing formwork body is all one piece, which is very inconvenient during installation and use, and improves the practicality of the formwork body.

[0016] 2. In this utility model, the cooperation between the sliding groove and the slider can complete the rapid assembly of the template body, which greatly simplifies the operation steps. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figure 1 - Figure 4 As shown, this utility model provides a shear wall formwork for an elevator shaft, including a formwork body 1. A portable folding support assembly 2 is connected to the center of the bottom rear end of the formwork body 1. The portable folding support assembly 2 includes a first rotating shaft 201. A main support plate 202 is connected to the surface of the first rotating shaft 201. A groove 203 is formed on one side surface of the main support plate 202. A slot 204 is formed on the side of the main support plate 202 near the first rotating shaft 201. A magnetic block 205 is connected to the rear end of the main support plate 202. A connecting rod 206 is rotatably connected in the groove 203. A telescopic rod 209 is inserted into the connecting rod 206. A threaded hole 207 is formed on one side surface of the telescopic rod 209. The threaded hole 207 is provided with... The telescopic rod 209 has a first bolt 208. A rotating block 210 is connected to the front end of the telescopic rod 209. Holes 211 are opened on both sides of the rotating block 210. A second bolt 212 is inserted into the two sets of holes 211. The second bolt 212 passes through the hole 211 and forms a threaded connection with the template body 1. A magnet 213 is fitted into the template body 1 at the matching position with the magnetic block 205. The magnet 213 and the magnetic block 205 form a magnetic attraction connection. The outer surface of the telescopic rod 209 is in contact with the inner wall of the connecting rod 206. The telescopic rod 209 and the connecting rod 206 form a sliding connection. The size of the slot 204 matches the size of the rotating block 210. The rotating block 210 and the slot 204 form a snap-fit ​​connection.

[0026] The overall effect of Embodiment 1 is that, during the construction of the elevator shaft shear wall structure, the formwork body 1 can be moved to the designated position first, and then the main support plate 202 can be rotated open via the first rotating shaft 201. At this time, the connecting rod 206 in the groove 203 can be rotated out and pulled outward so that the connecting rod 206 can be pulled out from the formwork body 1, and the rotating block 210 rotates with the connecting rod 206. Then, the rotating block 210 is aligned with the threaded groove on the surface of the formwork body 1, and then the second bolt 212 can be inserted through the hole 211 and attached to the surface of the formwork body 1. The threaded groove can be used for threaded fixation. Then, the first bolt 208 is passed through the connecting rod 206 and threaded to the threaded hole 207 to form a threaded fixation. The shear wall structure is supported by the template body 1. After use, the two sets of second bolts 212 and first bolts 208 can be removed, and the telescopic rod 209 can be retracted into the connecting rod 206. Then, the connecting rod 206 can be rotated into the groove 203 so that the rotating block 210 can be inserted into the slot 204. Finally, the main support plate 202 can be rotated and retracted through the first rotating shaft 201 so that the magnetic block 205 can be magnetically fixed with the magnet 213.
