Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a reinforced structure for fair-faced concrete formwork assembly. Background Technology

[0002] Fair-faced concrete formwork is a special formwork system used for pouring fair-faced concrete. Its core purpose is to ensure that the concrete surface is flat and smooth with uniform texture after molding, without the need for secondary plastering or decoration, directly presenting the natural texture and color of the concrete. During the process of overlapping fair-faced concrete formwork, it is usually necessary to reinforce and support the formwork.

[0003] Currently, traditional formwork reinforcement structures mostly use rigid connection methods with fixed spacing, which makes it difficult to dynamically adjust or expand the reinforcement range according to the width of the formwork, resulting in poor flexibility. In addition, traditional formwork reinforcement structures use rigid connection nodes with fixed angles, which are difficult to adapt to the assembly requirements of non-right angle, arc or irregular concrete structures. If special angles are required, special accessories are often required, resulting in high costs and extended construction periods. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a fair-faced concrete formwork assembly and reinforcement structure that can flexibly adapt to different angle splicing requirements, thus solving the limitation of the single angle of traditional formwork reinforcement structures.

[0006] Multiple template bodies are spliced ​​together end to end to form the shape required for fair-faced concrete, thereby defining the pouring space of the fair-faced concrete;

[0007] Multiple reinforcement mechanisms are used to reinforce multiple template bodies. They are spliced ​​together end to end and the spacing between them is adjustable, and they surround the outside of the multiple template bodies. Each reinforcement mechanism includes a first vertical plate and a second vertical plate located at the splice of two adjacent template bodies and rotatably connected to each other. The first vertical plate is provided with a locking member for locking the first vertical plate and the second vertical plate after they rotate relative to each other.

[0008] The splicing mechanism for connecting adjacent reinforcement mechanisms includes a plurality of first connectors detachably mounted on one side of the first vertical plate and a plurality of second connectors detachably mounted on the side of the second vertical plate opposite to the first vertical plate and corresponding to the plurality of first connectors. The end of the first connector opposite to the first vertical plate is provided with a positioning bolt, and the second connector is provided with a positioning hole for the positioning bolt to be inserted to fix the first connector to the adjacent second connector, thereby splicing two adjacent reinforcement mechanisms.

[0009] Multiple support mechanisms for providing support for multiple reinforcement mechanisms, each of the support mechanisms including two adjustable fasteners that are obliquely connected between the first vertical plate and the ground and between the second vertical plate and the ground.

[0010] Preferably, a through hole is provided along the vertical direction of the first vertical plate, and a fixed shaft is coaxially rotatably connected in the through hole. The fixed shaft is fixedly connected to the side of the second vertical plate near the first vertical plate.

[0014] Preferably, the positioning hole is a waist-shaped hole opened in the second connecting plate in the horizontal direction, and a sliding space is formed in the waist-shaped hole for the positioning bolt to slide in the horizontal direction to adjust the distance between two adjacent reinforcing mechanisms.

[0015] Preferably, both the first vertical plate and the second vertical plate have reserved slots on their outer sides. Each of the fixing components includes a sleeve rotatably connected to the corresponding reserved slot and a movable rod movably inserted into the sleeve on the side opposite to the reserved slot. The end of the movable rod on the side opposite to the sleeve is provided with a tapered part for inserting into the ground to connect the reinforcement mechanism to the ground.

[0016] Preferably, a rotating shaft is fixedly connected to the end of the sleeve facing away from the movable rod, and the rotating shaft is rotatably connected to the inner wall of the reserved groove.

[0017] Preferably, the inner sides of the first vertical plate and the second vertical plate of each of the reinforcing mechanisms are provided with sealing gaskets.

[0018] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0019] 1) The first and second connecting parts are engaged with the positioning bolts through the waist-shaped holes, allowing the spacing between adjacent reinforcement mechanisms to be freely adjusted to meet the needs of different template widths. They also ensure that the first and second vertical plates are located at the splice joint between two adjacent template bodies.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1 to 7As shown, this utility model embodiment provides a reinforced assembly structure for fair-faced concrete formwork, including multiple formwork bodies 1, multiple reinforcing mechanisms 2 for reinforcing the multiple formwork bodies 1, a splicing mechanism for splicing adjacent reinforcing mechanisms 2 end to end, and multiple supporting mechanisms for supporting the multiple reinforcing mechanisms 2. The multiple formwork bodies 1 are spliced ​​end to end to form the desired shape of the fair-faced concrete, thus defining the pouring space for the fair-faced concrete. The multiple reinforcing mechanisms 2 are spliced ​​end to end and are arranged around the outside of the multiple formwork bodies 1 with adjustable spacing. Each reinforcing mechanism 2 includes a first vertical plate 21 and a second vertical plate 22 located at the splicing point of two adjacent formwork bodies 1 and rotatably connected to each other. The first vertical plate 21 is provided with a support mechanism for the first vertical plate 21 and... The locking member locks the two after the second vertical plate 22 rotates relative to each other; the splicing mechanism includes a plurality of first connecting members 23 detachably installed on one side of the first vertical plate 21 and a plurality of second connecting members 24 detachably installed on the side of the second vertical plate 22 facing away from the first vertical plate 21 and corresponding to the plurality of first connecting members 23. The end of the first connecting member 23 facing away from the first vertical plate 21 is provided with a positioning bolt 234, and the second connecting member 24 is provided with a positioning hole 244 for the positioning bolt 234 to be inserted to fix the first connecting member 23 to the adjacent second connecting member 24, thereby splicing the two adjacent reinforcement mechanisms 1; each support mechanism includes two fixing members 26 that are obliquely connected between the first vertical plate 21 and the ground and between the second vertical plate 22 and the ground and whose length is adjustable.

[0033] Furthermore, in this embodiment, a through hole is provided vertically on the first vertical plate 21, and a fixed shaft 27 is coaxially rotatably connected within the through hole. The fixed shaft 27 is fixedly connected to the side of the second vertical plate 22 near the first vertical plate 21. By using the fixed shaft 27 that penetrates the first vertical plate 21, the first vertical plate 21 and the second vertical plate 22 can rotate around the fixed shaft 27, thereby adjusting the angle between the first vertical plate 21 and the second vertical plate 22. Preferably, in this embodiment, the locking component includes a fastening screw hole 28 provided on the outer wall of the first vertical plate 21 and a fastening bolt 29 threaded into the fastening screw hole 28. By setting the fastening bolt 29 to lock the first vertical plate 21 and the second vertical plate 22 after they rotate to adjust their angle, the angle is fixed, preventing relative rotation between the two.

[0034] Please see Figure 3 and Figure 4As shown, the first connecting member 23 includes a first connecting plate 231, a first mounting block 232 is fixedly connected to the first end of the first connecting plate 231, the first mounting block 232 is detachably connected to the first vertical plate 21 by a first mounting bolt 233, and a positioning bolt 234 is threadedly connected to the second end of the first connecting plate 231. Preferably, in this embodiment, the second connecting member 24 includes a second connecting plate 241, and a second mounting block 242 is fixedly connected to the end of the second connecting plate 241 that is relatively closer to the second vertical plate 22. The second mounting block 242 is detachably connected to the second vertical plate 22 by a second mounting bolt 243. It should be noted that in this embodiment, the positioning hole 244 is a waist-shaped hole opened in the second connecting plate 241 along the horizontal direction, and a sliding space is formed in the waist-shaped hole for the positioning bolt 234 to slide in the horizontal direction to adjust the distance between the two adjacent reinforcing mechanisms 2. By locking the positioning bolt 234, the two adjacent reinforcing mechanisms 2 are fixed. With the setting of the first connecting member 23 and the second connecting member 24, the distance between the two adjacent reinforcing mechanisms 2 can be freely adjusted. It is suitable for template bodies 1 of different widths. It can ensure that the first vertical plate 21 and the second vertical plate 22 are located at the splice seam between the two adjacent template bodies 1. By removing the positioning bolt (234), the number of reinforcing mechanisms (2) can be increased or decreased, so as to flexibly respond to engineering changes.

[0035] Furthermore, such as Figure 5 As shown, each reinforcement mechanism 2 has a sealing gasket 210 on the inner side of the first vertical plate 21 and the second vertical plate 22. Since the first vertical plate 21 and the second vertical plate 22 are located at the splice joint between two adjacent template bodies 1, the sealing gasket 210 can seal the splice joint between two adjacent template bodies 1, thus preventing grout leakage at the splice joint during concrete pouring.

[0036] Please see Figure 3 , Figure 4 and Figure 7 As shown, in this embodiment, both the first vertical plate 21 and the second vertical plate 22 have reserved slots 25 on their outer sides. Each fixing member 26 includes a sleeve 261 rotatably connected to the corresponding reserved slot 25 and a movable rod 263 movably inserted into the sleeve 261 on the side opposite to the reserved slot 25. The end of the movable rod 263 on the side opposite to the sleeve 261 is provided with a tapered part 264 for inserting into the ground to connect the reinforcement mechanism 2 to the ground. Preferably, a rotating shaft 262 is fixedly connected to the end of the sleeve 261 on the side opposite to the movable rod 263. The rotating shaft 262 is rotatably connected to the inner wall of the reserved slot 25 (a damped rotation connection method can be adopted). The outer wall of the movable rod 263 is provided with external threads. The movable rod 263 is threadedly connected to the sleeve 261. A rotating cylinder 265 is also installed on the outer wall of the movable rod 263 to facilitate the worker to rotate the movable rod 263 to adjust its length.

[0037] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
