Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an induction joint structure for cracking of ultra-long clear-faced concrete. Background Art
[0002] In the production process of plain concrete, induced joint technology is often used. The induced joint is a pre-designed crack that can guide the concrete to crack at a specific location through reasonable setting, thereby releasing internal stress and reducing the occurrence of unexpected cracks.
[0003] However, the existing ultra-long plain concrete structure has certain limitations due to its large length and high wall rigidity, which makes the wall prone to cracks and is easily affected by factors such as temperature changes, shrinkage and expansion, leading to cracking, thereby affecting normal use and overall aesthetics. Utility Model Content
[0004] In order to solve the above technical problems, the utility model proposes an induction joint structure for cracking of ultra-long plain concrete. By setting the induction joint, the plain concrete wall can be prevented from cracking due to temperature changes, shrinkage and expansion and other factors.
[0005] The technical solution for achieving the purpose of the utility model is: an induced joint structure for cracking of ultra-long plain concrete, comprising a plurality of symmetrically arranged plain formworks, a plain steel frame formwork being commonly provided on one side of the plurality of plain formworks, an open seam strip being commonly fixedly installed between a pair of adjacent plain formworks, and a plurality of sets of self-tapping screws being threadedly connected between the open seam strip and the plain formwork.
[0006] Preferably, fair-faced concrete is poured between a pair of the fair-faced formworks and the exposed joint strips.
[0007] Preferably, an inducing seam strip is provided between a pair of adjacent plain concrete formworks, and one end of the inducing seam strip is embedded in the surface of the plain concrete.
[0008] Preferably, a rubber strip is pasted on one side of the inducing seam strip, the inducing seam strip and the clear water formwork are pasted together by the rubber strip, and a plurality of T-shaped blocks are fixedly installed on one end of the inducing seam strip.
[0009] Compared with the prior art, the present invention has the following significant advantages:
[0010] First: The utility model uses the method of pasting to install the induced seam strip, so that it is easy to form an induced seam that meets the requirements during pouring, and the water-clearing effect is greatly improved. The width of the seam meets the requirements of the architect, and a T-shaped block is provided at the tail of the induced seam strip, so that it is convenient to remove it later and recycle it to improve the utilization rate. In addition, the induced seam can be set at will without affecting the water-clearing effect, and it is convenient for the structural engineer to solve the problem of crack resistance.
[0011] Secondly, the induced joints provided in the present invention are weak connections. Under normal circumstances, the induced joints will not crack. The exposed joints provided can completely disconnect the plain concrete and achieve segmented processing, thus avoiding the problem of cracks easily occurring in plain concrete walls due to their large rigidity, thereby improving the overall aesthetics of the plain concrete.
[0012] The invention solves the problem that the existing super-long plain concrete structure is easy to crack due to its large length and large wall rigidity, and is easily affected by factors such as temperature changes, shrinkage and expansion, resulting in cracking, thereby affecting normal use and overall aesthetics.

[0019] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] The utility model provides an improved induction joint structure for cracking of ultra-long clear-faced concrete. The technical solution of the utility model is:
[0021] like Figure 1-3 As shown, an induced joint structure for cracking of super-long plain concrete is shown, comprising a plurality of symmetrically arranged plain formworks 1, a plain steel frame formwork 5 being commonly provided on one side of the plurality of plain formworks 1, an open seam strip 2 being commonly fixedly installed between a pair of adjacent plain formworks 1, a plurality of groups of self-tapping screws 3 being threadedly connected between the open seam strip 2 and the plain formwork 1, the arranged plain formwork 1 is convenient for pouring plain concrete 4, the arranged plain steel frame formwork 5 is convenient for providing support to the plain formwork 1 to prevent the plain formwork 1 from loosening during pouring and affecting the molding quality of the plain concrete 4, in addition, the arranged open seam strip 2 is convenient for segmented processing of the plain concrete 4, avoiding the problem that cracks are easily generated in walls with relatively long lengths due to the relatively large rigidity of the walls, and the arranged self-tapping screws 3 are convenient for stably fixing the open seam strip 2 on the plain formwork 1, so as to facilitate removal together with the plain formwork 1.
[0022] Furthermore, fair-faced concrete 4 is poured between a pair of fair-faced formworks 1 and the open seam strips 2. By setting the open seam strips 2, the fair-faced concrete 4 can be separated during pouring to achieve a segmented treatment and prevent more cracks from occurring due to a longer wall.
[0023] As a further solution of the present invention, an inducing seam strip 6 is commonly provided between a pair of adjacent plain concrete formworks 1, and one end of the inducing seam strip 6 is embedded in the surface of the plain concrete 4. The inducing seam strip 6 is provided to facilitate the formation of an induced seam, thereby reducing the number of cracks in the wall under normal use.
[0024] Furthermore, a rubber strip 7 is pasted on one side of the induced seam strip 6, and the induced seam strip 6 and the clear water formwork 1 are pasted together by the rubber strip 7. A plurality of T-shaped blocks 8 are fixedly installed on one end of the induced seam strip 6. The set rubber strip 7 facilitates the installation of the induced seam strip 6, so that when the clear water steel frame formwork 5 and the clear water formwork 1 are removed, the induced seam strip 6 can be retained in the concrete, and the induced seam strip 6 can be removed when the strength is reached. The later the induced seam strip 6 is removed, the better the effect of the clear water concrete 4 molding is. The set T-shaped block 8 facilitates the later removal of the induced seam strip 6.
[0025] The specific working method is: first, the steel cage for pouring the plain concrete 4 is tied, and then the plain formwork 1 is set on the outside of the steel cage, and the induced seam strips 6 are pasted between adjacent plain formworks 1. At the same time, an open seam strip 2 is set at the position where the plain concrete 4 is segmented, and the open seam strip 2 is fixed to the plain formwork 1 with self-tapping screws 3, so that it is convenient to remove it together with the plain formwork 1 later. After installation, the plain concrete 4 is poured. After the plain concrete 4 is formed, the plain steel frame formwork 5 and the plain formwork 1 are removed, and the induced seam strip 6 is reserved in the concrete. After the strength of the plain concrete 4 reaches a certain level, the induced seam strip 6 is removed. The later the induced seam strip 6 is removed, the better the effect of the forming of the plain concrete 4. The T-shaped block 8 is provided to facilitate the later removal of the induced seam strip 6, and finally form an induced seam, which can reduce the number of wall cracks in the later stage and further improve the forming quality and aesthetics of the plain concrete 4.
[0026] The technical means disclosed in the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
