Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an aluminum formwork for composite building panels. Background Technology

[0002] Composite slab aluminum formwork is a type of aluminum formwork specifically designed for composite slab construction. Composite slab is a building material consisting of precast concrete slabs and cast-in-place concrete layers. The aluminum formwork is used in the production process of precast concrete slabs. Features of this aluminum formwork include its lightweight nature, ease of installation and disassembly, making it particularly suitable for high-rise buildings and complex structures. It can also be reused multiple times, saving material costs and improving construction efficiency. Furthermore, its smooth surface ensures the dimensional accuracy and surface quality of the precast concrete slabs.

[0003] A search revealed Chinese Patent Publication No. CN208168340U, which discloses an aluminum alloy formwork for composite floor slab construction. This formwork includes aluminum alloy templates for casting cast-in-place walls, beams, and strips. The aluminum alloy templates comprise floor corner templates, wall / beam templates, beam side templates, strip support templates, transverse tie templates, and longitudinal tie templates. The floor corner templates are located at the floor corners, and the wall / beam templates are located on the sides of the cast-in-place walls. The beneficial effect of this invention is that it allows for the one-time installation of corresponding aluminum alloy templates at structural locations such as walls and beams, followed by installation... The construction method of installing horizontal composite floor slabs and finally pouring concrete for the composite layers of walls, beams and floor slabs to form a spatial structure combines the advantages of aluminum formwork and prefabricated structures, greatly improving construction efficiency. However, it still uses bolted connections and pouring, which, while having a certain degree of stability, has significant shortcomings in terms of ease of disassembly and material reuse, leading to reduced construction efficiency and increased construction costs. Furthermore, the connection between the aluminum alloy formwork and the composite slabs is prone to loosening, resulting in gaps and leakage of the filling material, which reduces construction quality and practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an aluminum formwork for composite slabs, aiming to improve the existing aluminum formwork for composite slabs. The existing method of connecting aluminum formwork still uses bolts and pouring, which has obvious deficiencies in terms of ease of disassembly and material reuse rate, resulting in reduced construction efficiency and increased construction costs.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an aluminum formwork for composite building slabs, including a supporting beam, with multiple beam seats fixedly connected to the bottom of the supporting beam, and support heads fixedly connected to both the left and right sides of the supporting beam.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of an aluminum formwork for composite building panels, including a supporting beam 1. Multiple beam seats 10 are fixedly connected to the bottom of the supporting beam 1. The supporting beam 1 is the supporting structure of the entire structure. Support heads 4 are fixedly connected to both the left and right sides of the supporting beam 1. An installation groove 11 is provided on the inner wall of the beam seat 10. A connecting rod 7 is slidably connected to the bottom of the inner wall of the beam seat 10. The support head 4 is used for installing and assisting in supporting the remaining structures. A locking block 6 is fixedly connected to an adjacent end of the connecting rod 7. A second bolt 8 is threadedly connected to the inner wall of the connecting rod 7. An installation nut 9 is provided on the outer wall of the second bolt 8. The locking block 6 can engage with the remaining blocks.

Multiple installation structures 2 are fixedly connected to the bottom of the aluminum formwork 3. The installation structures 2 are used for pressing and installing. The second slot 5 is used to engage with the locking block 6.

[0041] Specifically, the supporting beam 1 can steadily bear the pressure transmitted from above during the construction process. The beam seat 10 provides a supporting foundation for the supporting beam 1. The supporting head 4 has sufficient strength to support other structural components connected to it, ensuring that it will not loosen during use. The second nut 9 is screwed into the second bolt 8. By tightening the second nut 9, the connecting rod 7 can be fixed in the required position to prevent it from shifting during use. The locking block 6 has a trapezoidal structure, which can better engage with the second locking groove 5.

[0042] Please see the appendix Figure 2 - Appendix Figure 4 The installation structure 2 includes an installation block 209. The top of the installation block 209 is fixedly connected to the bottom of the aluminum template 3. The installation block 209 is used to install the bottom structure of the aluminum template 3. A first bolt 210 is threadedly connected to the inner wall of the installation block 209. An installation rod 202 is provided on the outer wall of the first bolt 210. An installation nut 211 is threadedly connected to the outer wall of the first bolt 210 near the edge. The first bolt 210 is used to limit the position of the installation rod 202. Multiple first slots 204 are opened on the inner wall of the installation rod 202. A limiting plate 206 is provided in the middle of the outer wall. The mounting nut 211 can limit the first bolt 210. A first sliding groove 207 is provided on the top of the limiting plate 206. A pin 203 is slidably connected to the inner wall of the first slot 204. The pin 203 can be inserted into the first slot 204 to limit the structure. A positioning block 205 is provided in the middle of the outer wall of the pin 203. A screw 208 is threaded to the opposite end of the pin 203. A precast floor slab 201 is provided at the bottom of the limiting plate 206. The positioning block 205 can compress the precast floor slab 201 and the aluminum template 3.

[0043] Specifically, the installer can fix the mounting rod 202 to the first bolt 210 by tightening the mounting nut 211, ensuring that the mounting rod 202 will not shake or shift at will. The first sliding groove 207 and the positioning block 205 cooperate with each other, making the pin 203 more stable during sliding. At the same time, the first sliding groove 207 and the positioning block 205 can limit the position of the limiting plate 206. The installer can further fix the position of the pin 203 by tightening the screw 208, preventing it from loosening due to vibration or other reasons during use.

[0044] Please see the appendix Figure 3 - Appendix Figure 5 The inner wall of the beam 1 has multiple hollow grooves 12. The front and rear sides of the aluminum template 3 have grooves 13. The grooves 13 are used to install and connect the other structures. A third washer 20 is provided on the side adjacent to the mounting nut 211. The inner wall of the third washer 20 is slidably connected to the outer wall of the first bolt 210. The third washer 20 is used to prevent the mounting nut 211 from loosening after long-term use. Multiple reinforcing bars 14 are fixedly connected to the inner wall of the precast floor slab 201. A protective sleeve 16 is provided at the far end of the first bolt 210. A first washer 15 is provided on the rear side of the screw 208. The protective sleeve 16 is used to prevent the first bolt 210 from rusting and being damaged after long-term use.

[0045] Specifically, the first washer 15 increases the contact area between the screw 208 and other components, disperses the pressure generated when the screw 208 is tightened, and avoids damage to components due to excessive local pressure. It also helps to improve the tightness of the connection. The protective sleeve 16 can protect the end of the first bolt 210, preventing the bolt end from being hit during construction and avoiding damage to the stability of the entire installation structure 2. It can also prevent the bolt from rusting to a certain extent and extend its service life.

[0046] Please see the appendix Figure 4 - Appendix Figure 6 The outer wall of the mounting nut 2 9 is provided with a second washer 19. The inner wall of the second washer 19 is slidably connected to the outer wall of the second bolt 8. The second washer 19 is used to prevent the mounting nut 2 9 from loosening after long-term use. The outer wall of the connecting rod 7 is fixedly connected with a protective sleeve 2 17. Multiple support heads 4 are all fixedly connected at the same horizontal height. The protective sleeve 2 17 is used to protect the outer wall of the connecting rod 7. The outer ends of the second bolt 8 are provided with protective sleeves 3 18. The inner wall of the protective sleeve 3 18 is threadedly connected to the outer wall of the second bolt 8. The protective sleeve 3 18 is used to protect the end of the second bolt 8.

[0047] Specifically, the protective sleeve 17 can not only effectively prevent surface damage to the connecting rod 7 caused by collisions, scratches, etc. during construction, and avoid corrosion risks caused by surface damage, but also reduce the friction coefficient between the connecting rod 7 and other components to a certain extent, making the sliding process of the connecting rod 7 at the bottom of the inner wall of the beam seat 10 smoother. The second washer 19 can effectively buffer the rigid contact force between the mounting nut 2 9 and other components, and avoid wear or damage to the surface of the components caused by over-tightening.

[0048] Working principle: When installing aluminum formwork, first place aluminum formwork 3 between adjacent support heads 4, then insert connecting rod 7 into second slot 5 to drive clamp 6, thereby limiting and supporting aluminum formwork 3 through clamp 6 on both sides. Then insert second bolt 8, so that it passes through connecting rod 7 and through installation slot 11 in beam seat 10. Then screw on the second mounting nut 9 and second washer 19 on both sides in sequence to limit connecting rod 7.

[0049] When connecting the aluminum template 3 and the precast floor slab 201, first place the precast floor slab 201 on top of the aluminum template 3, then insert the mounting rod 202 into the corresponding hole until the bottom end of the mounting rod 202 contacts the top of the mounting block 209, insert the first bolt 210 so that it passes through the mounting block 209 and the mounting rod 202 to limit the mounting rod 202, then rotate the mounting nut 211 to install the first bolt 210, then insert the pin 203 into the first slot 204, then insert the positioning block 205 into its two ends, adjust it to be inserted into different first slots 204 until the limiting plate 206 is in contact with the top of the precast floor slab 201, and at the same time the bottom of the positioning block 205 is in contact with the inner wall of the first sliding groove 207, then screw the screw 208 into the two ends of the pin 203 to limit it.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
