Description

Technical Field

[0001] The present invention relates to the technical field of construction, and particularly relates to an end aluminum alloy formwork tying structure for chimney reinforcement. Background Art

[0002] During the construction of a chimney, in order to improve construction efficiency and ensure the accuracy and durability of the structure, aluminum alloy formwork is usually used for the construction of key parts. During the construction process, the reinforcement and support of the aluminum alloy formwork are important links to ensure construction safety and quality.

[0003] In the traditional reinforcement process, for the end aluminum alloy formwork of chimney reinforcement, steel rods or screw parts are usually used to connect the formwork with the support frame, and then screw parts (the screw parts are inclined) are inserted between two adjacent formworks to tie the mating ends of the adjacent formworks (as Figure 13 shown). However, during the connection of two adjacent formworks with inclined screw parts, the screw parts need to pass through two groups of corresponding inclined holes for tying. In the actual formwork reinforcement process, the splicing and alignment of the adjacent formwork ends are not necessarily accurate, and there is a problem that the positions of some formwork ends are offset. Due to the inaccurate splicing and alignment of the formwork ends, the posture of the formwork needs to be adjusted repeatedly during the insertion and installation of the screw parts. Construction workers need to spend a long time on manual operation, and especially during high-altitude operations, the complex bolt connection alignment makes the construction efficiency low and the labor intensity of construction workers is relatively large.

[0004] Therefore, there is an urgent need for a new end aluminum alloy formwork tying structure for chimney reinforcement to simplify the chimney formwork reinforcement process and improve construction efficiency and safety. Summary of the Invention

[0005] The purpose of the present invention is to provide an end aluminum alloy formwork tying structure for chimney reinforcement, which solves the problems that in the traditional reinforcement process, due to the inaccurate splicing and alignment of the formwork ends, the posture of the formwork needs to be adjusted repeatedly during the insertion and installation of the screw parts, resulting in low construction efficiency and relatively large labor intensity of construction workers.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0048] Embodiment 1

[0049] As Figures 1 - 12As shown in the figure, this embodiment provides an end aluminum alloy formwork tie structure for chimney reinforcement. This structure includes an outer rib member 1 connected to the outer aluminum alloy formwork and an inner rib member 2 connected to the inner aluminum alloy formwork. A plurality of first reinforcement components 3 are arranged between the outer rib member 1 and the inner rib member 2. The outer rib member 1 and the inner rib member 2 are connected together by a plurality of first reinforcement components 3 arranged at equal intervals to realize the reinforcement of the inner and outer aluminum alloy formworks. And a second reinforcement component 4 is arranged between the mating ends of two adjacent outer rib members 1 to tie and reinforce the mating ends of the end aluminum alloy formwork.

[0050] It should be noted that the outer rib member 1 in this embodiment also needs to be fixedly connected to the corresponding external support frame through a screw. Synchronously, the lengths of the outer rib member 1 and the inner rib member 2 can be cut as required according to the actual chimney size.

[0051] As Figure 1 and Figure 2 As shown in the figure, the outer rib member 1 in this embodiment includes a pair of rectangular steel pipes 11 symmetrically arranged up and down, and a plurality of support members 12 are connected between the two groups of rectangular steel pipes 11. The inner rib member 2 in this embodiment includes a pair of rectangular steel pipes 21 symmetrically arranged up and down, and a plurality of support members 22 are arranged between the two groups of rectangular steel pipes 21. The plurality of support members 22 fix the two groups of rectangular steel pipes 21 distributed up and down together. Among them, both the support member 22 and the support member 12 are made by cutting the redundant rectangular steel pipes on the construction site.

[0052] It should be noted that the outer rib member 1 and the inner rib member 2 in this embodiment can be prefabricated parts or welded on site, which has a certain degree of flexibility. When using waste steel pipes for preparation, the waste materials are recycled, and further construction costs are saved.

[0053] As Figure 1 and Figure 2 As shown in the figure, the above-mentioned first reinforcement component 3 includes a reinforcement plate 31 clamped on the outer rib member 1 and the inner rib member 2. The two reinforcement plates 31 are arranged correspondingly, and a fixing screw 33 is arranged between the two reinforcement plates 31. Both ends of the fixing screw 33 pass through the reinforcement plate 31 and are connected with fixing nuts 34. A backing plate 32 is arranged between the two fixing nuts 34 and the corresponding reinforcement plate 31, and the backing plate 32 is sleeved on the fixing screw 33.

[0054] It should be noted that the reinforcement plate 31 in this embodiment is in a semi-I shape with the openings facing each other. By clamping with the semi-I-shaped reinforcement plate 31, the contact area between the reinforcement plate 31 and the outer rib member 1 or the inner rib member 2 is increased, thereby ensuring the stability of the reinforcement.

[0055] During installation, the two reinforcement plates 31 are clamped on the corresponding outer ribbed member 1 or inner ribbed member 2, and then the fixing screw 33 is inserted (the fixing screw 33 and the corresponding through hole on the reinforcement plate 31 are slidingly set), the pads 32 at both ends are put on, and the corresponding fixing nuts 34 are screwed on to complete the assembly of the first reinforcement component 3, thereby realizing the reinforcement of the inner and outer aluminum alloy templates.

[0056] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, a second reinforcement component 4 is provided to tie and reinforce the mating end of the end aluminum alloy formwork. During reinforcement, one end is fixed and the other end is installed from the outside with a deflection. There is no need to repeatedly calibrate the tie structure, and it can be installed quickly and conveniently from the outside, which improves construction efficiency and reduces the labor intensity of construction workers.

[0057] The second reinforcement component 4 in this embodiment includes a connecting base 41 connected to one outer corrugated member 1 and a fixing plate 42 connected to an adjacent outer corrugated member 1, and a tie assembly 43 is provided between the connecting base 41 and the fixing plate 42 to tie two adjacent outer corrugated members 1 together, thereby tying the template.

[0058] Specific as Figures 3 - 5 As shown, the connection base 41 in this embodiment includes a connection steel plate 411 connected to the outer end of the rectangular steel pipe 11, and a steering base 412 is arranged between the two connection steel plates 411. One end of the above-mentioned anchor assembly 43 is arranged on the steering base 412 to realize the deflection of the anchor assembly 43.

[0059] More specifically, Figure 12 As shown, the above-mentioned steering base 412 includes a rectangular locking body 4121, which ensures the balance of locking force. Rotating shafts 4122 are symmetrically arranged at both ends of the locking body 4121. The rotating shaft 4122 is rotatably connected to the connecting steel plate 411. A locking hole 4123 is opened in the middle of the locking body 4121, and one end of the tie assembly 43 is arranged through the locking hole 4123. The tie assembly 43 can be adjusted through the steering base 412, thereby tying the adjacent outer ribs 1 together.

[0060] The fixing plate 42 in this embodiment is arranged in a triangular shape, and a slot 421 is transversely provided in the middle of the fixing plate 42, and a positioning hole 422 is provided at the end away from the steering base 412. One end of the slot 421 is connected to the positioning hole 422, and the other end passes through the fixing plate 42. A guiding surface is also provided on the outer side of the slot 421 to facilitate the clamping of the tie assembly 43.

[0061] In order to further ensure the locking force of the template after tensioning, the aperture of the positioning hole 422 is larger than 1.5 times the width of the slot 421, so that after the tensioning assembly 43 is installed, when the outer ribbed member 1 is subjected to outward pressure, it can be stably limited without slipping, thereby providing sufficient locking force.

[0062] Furthermore, if Figures 6 - 11 As shown, the tie assembly 43 in this embodiment includes a tie screw 431, one end of which passes through the locking hole 4123 of the steering base 412, and a locking pad 433 is sleeved on the end of the tie screw 431 close to the steering base 412, and a locking nut 432 is threadedly connected to the outer side of the locking pad 433 of the tie screw 431, and a locking piece 434 is threadedly connected to the other end of the tie screw 431, and a locking piece 434 is installed inside the locking piece 434. A spring 435 is installed, and the spring 435 is sleeved on the tie screw 431. A positioning piece 436 is connected to the other end of the spring 435. During installation, the positioning piece 436 is moved to make the tie screw 431 pass through the groove 421 from the outside of the outer ribbed piece 1 and be clamped in the fixing plate 42. Then the positioning piece 436 is released and inserted into the positioning hole 422 to achieve positioning. Then the locking piece 434 is rotated to squeeze the positioning piece 436 to make the positioning stable and prevent it from falling off.

[0063] In addition, the integral tie assembly 43 is easy to install and disassemble, and can be integrated with the outer rib member 1 or installed and disassembled separately.

[0064] Specific as Figure 7 and Figure 9 As shown, the locking member 434 in this embodiment includes a locking nut 4341 threadedly connected to the tie screw 431, a locking pad 4342 is welded to the inner end of the locking nut 4341, the inner side surface of the locking pad 4342 is connected to a locking sleeve 4343, a matching groove 4344 is opened inside the locking sleeve 4343, the above-mentioned spring 435 is arranged in the matching groove 4344, and is sleeved on the tie screw 431.

[0065] Specific as Figure 10 and Figure 11 As shown, the positioning member 436 in this embodiment includes a limit platform 4361 and a positioning platform 4362, wherein the diameter of the positioning platform 4362 is adapted to the positioning hole 422, or the diameter of the positioning platform 4362 is loosely matched with the positioning hole 422, and the diameter of the positioning platform 4362 is larger than the width of the slot 421, and the diameter of the limit platform 4361 mentioned above is larger than 1.5 times the diameter of the positioning platform 4362, thereby achieving stable extrusion force and ensuring the stability of the tie.

[0066] It should be noted that the head of the positioning platform 4362 in this embodiment is provided with a guide surface for guiding during installation and insertion to facilitate positioning.

[0067] Further, an assembly groove 4363 is formed on the limiting platform 4361 close to one side of the locking member 434, and the other end of the spring 435 is connected to the assembly groove 4363. A through hole 4364 is formed in the middle of the limiting platform 4361, and the through hole 4364 runs through the limiting platform 4361 and the positioning platform 4362, and the pull rod 431 is slidably arranged in the through hole 4364.

[0068] During installation, one section of the pull rod 431 passes through the locking hole 4123, the first locking backing plate 433 is sleeved, and then the first locking nut 432 is screwed on. The pull rod assembly 43 is rotated around the steering base 412. When it is close to the fixed plate 42, the positioning member 436 is pushed backward, so that the pull rod 431 passes through the through groove 421 to reach the positioning hole 422. Then the positioning member 436 is released, so that the positioning platform 4362 is inserted into the positioning hole 422, and the locking member 434 is rotated. The positioning member 436 is squeezed through the locking sleeve 4343 to realize the locking of the positioning member 436 and the fixed plate 42.

[0069] Embodiment 2

[0070] In order to make the installation and disassembly more convenient and improve the construction efficiency, in this embodiment, the first locking nut 432 and the first locking backing plate 433 are optimized (removed) on the basis of Embodiment 1. One end of the pull rod 431 is directly connected to the locking hole 4123 of the steering base 412. The connection method can be welding or a detachable connection, such as a threaded connection.

[0071] Furthermore, during reinforcement, only the position between the pull rod assembly 43 and the fixed plate 42 needs to be adjusted to fix the fixed plate 42 and the pull rod assembly 43, further simplifying the installation and disassembly process, improving the construction efficiency and reducing the labor intensity.

[0072] In this embodiment, pull rings can also be arranged at both ends of the limiting platform 4361 to facilitate the backward pushing of the positioning member 436.
