Description

Technical Field

[0001] This utility model relates to the field of aluminum formwork technology, specifically to an aluminum formwork for building engineering. Background Technology

[0002] Aluminum formwork, also known as aluminum alloy formwork for concrete engineering, is a high-efficiency and environmentally friendly construction formwork system. Aluminum formwork is formed by extrusion equipment and is spliced ​​in construction projects to form a casting model. Reinforcing bars are placed in the cavity of the spliced ​​parts, and concrete is poured into the cavity to form the building structure.

[0003] Existing aluminum formwork mainly includes flat aluminum formwork, back reinforcing rib structure, fastening structure, etc. During the splicing of aluminum formwork, external support structure is also required to improve the stability of aluminum formwork. Adjacent aluminum formwork is spliced ​​and fixed with bolts. After the construction project is completed, the aluminum formwork needs to be dismantled, stacked and transported to the next construction site. However, during transportation, because the aluminum formwork needs to be stacked and transported, the vibration and bumps generated during the transportation route will cause the aluminum formwork at the bottom layer to deform, which will easily cause the surface of the aluminum formwork to be uneven, ultimately leading to structural defects after the building structure is poured and formed. Utility Model Content

During the transportation of aluminum formwork, the aluminum formwork needs to be stacked and transported. The vibration and bumps generated during the transportation process will cause the aluminum formwork at the bottom layer to deform, which will easily cause the surface of the aluminum formwork to be uneven, and ultimately lead to structural defects after the building structure is poured and formed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aluminum formwork for construction engineering includes an aluminum alloy plate, an outer frame fixed to the rear surface of the aluminum alloy plate, a reinforcing strip provided on the rear surface of the aluminum alloy plate, a reinforcing frame provided on one side of the outer frame, a gasket provided between the outer frame and the reinforcing frame, a fastener provided between the outer frame and the reinforcing frame, and threaded holes provided on the outer walls of both the outer frame and the reinforcing frame.

[0007] Preferably, the fastener includes a fastening bolt, and positioning screw holes are provided at the four corners of the outer frame and through holes are provided at the four corners of the reinforcing frame. The screw end of the fastening bolt passes through the through hole and is threadedly connected to the positioning screw hole.

[0008] Preferably, the rear surface of the outer frame is provided with a slot, and the rear surface of the gasket is fixed with a protrusion, which is adapted to the slot.

[0009] Preferably, the front surface of the reinforcing frame is provided with a mounting groove, a support block is provided in the mounting groove, the front surface of the support block is provided with a groove, and a threaded hole is provided inside the groove.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1 - Figure 8 The aluminum formwork for building construction shown includes an aluminum alloy plate 3, an outer frame 1 fixed to the rear surface of the aluminum alloy plate 3, reinforcing strips 4 provided on the rear surface of the aluminum alloy plate 3, a reinforcing frame 2 provided on one side of the outer frame 1, a gasket 7 provided between the outer frame 1 and the reinforcing frame 2, fasteners provided between the outer frame 1 and the reinforcing frame 2, and threaded holes provided on the outer walls of both the outer frame 1 and the reinforcing frame 2. The aluminum alloy plate 3 and the reinforcing frame 2 are integral structures, obtained by extrusion processing using external extrusion equipment. The surface of the aluminum alloy plate 3 is horizontal. In the specific construction process, the aluminum formwork of this application is assembled on the outside of the steel structure of the building in a splicing manner. With the steel structure as the foundation and the casting mold composed of aluminum formwork as the auxiliary, concrete is finally poured into the casting mold cavity to obtain the building structure. The specific method of concrete pouring construction is prior art and will not be elaborated here. In building construction, the building structure cast in the casting mold obtained by splicing aluminum formwork is complete and intact, which is conducive to improving the quality of the building structure.

[0027] The fasteners include fastening bolts 15. Positioning screw holes 11 are provided at each of the four corners of the outer frame 1, and through holes 13 are provided at each of the four corners of the reinforcing frame 2. Through holes 13 are also provided at each of the four corners of the gasket 7. The screw end of the fastening bolt 15 passes through the through holes 13 and is threadedly connected to the positioning screw holes 11. It should be noted that during the assembly of the aluminum template of this application, the specific operation is as follows: First, place the gasket 7 on the surface of the outer frame 1, aligning the edge of the gasket 7 with the edge of the outer frame 1. Then, align the edge of the reinforcing frame 2 with the edge of the outer frame 1. Finally, pass the fastening bolt 15 through the through holes 13 and thread it into the through holes 13. With the connection of the fastening bolt 15, the outer frame 1 and the reinforcing frame 2 are stably connected and will not loosen.

[0028] like Figure 1 - Figure 5 As shown, a slot 10 is provided on the rear surface of the outer frame 1, and a protrusion 9 is fixed on the rear surface of the gasket 7. The protrusion 9 is adapted to the slot 10. When installing the gasket 7, the protrusion 9 on the rear surface of the gasket 7 is directly inserted into the slot 10, and the surface of the gasket 7 is tightly fitted with the surface of the outer frame 1. Finally, the outer frame 1 and the reinforcing frame 2 are connected, and the gasket 7 is clamped. During transportation, the gasket 7 has the function of buffering and resisting pressure. Under the protection of the reinforcing frame 2, during the stacking of aluminum templates, the gasket 7 and the reinforcing frame 2 absorb most of the force and play a good protective role.

[0029] like Figures 1-7 As shown, the front surface of the reinforcing frame 2 has an installation groove 21, in which a support block 8 is provided. The front surface of the support block 8 has a groove, and the inner side of the groove has a threaded hole. A limit rod 14 is provided on one side of the groove on the front surface of the support block 8. The limit rod 14 is locked in the groove and connected to the support block 8 by bolts. In the splicing process of the aluminum template in this application, the outer frames 1 of two adjacent aluminum templates are fitted together and fixed with bolts. Finally, the limit rod 14 is locked into the groove of the support block 8, and the support block 8, the limit rod 14 and the reinforcing frame 2 are connected with bolts. Multiple aluminum templates can be connected by using the limit rod 14 to improve the overall stability of the aluminum template.

[0030] like Figure 1 - Figure 6As shown, a pin 22 is provided on the rear surface of the reinforcing frame 2, and an insertion hole 101 that mates with the pin 22 is provided on the surface of the outer frame 1. A slot 12 is provided on the inner side of the reinforcing frame 2, and an auxiliary support strip 5 is provided on one side of the slot 12. Before the reinforcing frame 2 is fixed to the outer frame 1, the pin 22 is passed through the shim 7 (the surface of the shim 7 needs to be drilled, and the pin 22 passes through the drilled hole), and then inserted into the insertion hole 101, thereby completing the pre-fixation of the reinforcing frame 2 and the outer frame 1. In the specific use of aluminum template, the auxiliary support strip 5 can be pushed into the slot 12 to reinforce and support the reinforcing frame 2, improve the structural strength of the reinforcing frame 2, and avoid the problem of deformation of the reinforcing frame 2 caused by external force squeezing the reinforcing frame 2.

[0031] like Figure 1 As shown, a threaded seat 6 is provided on the bottom inner side of the outer frame 1. The surface of the threaded seat 6 is provided with a threaded hole. In the case of the aluminum formwork being vertically installed to form the side wall of the casting mold during construction, an external support pipe can be screwed onto one side of the threaded seat 6 through a thread. This external support pipe can then provide auxiliary support for the aluminum formwork, thereby improving the stability of the aluminum formwork and reducing the probability of it tipping over.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
