[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] See also Figures 1 to 7, the side formwork for the reserved exposed reinforced concrete surface provided by the present invention is now described. A side formwork for the reserved exposed reinforced concrete surface, comprising a bottom block 1, a first limit block 2, a second limit block 3 and a fixing rod 4, wherein the bottom block 1 is used to be installed on one side of a concrete surface 7; a fixing structure 11 is provided on the bottom block 1; the first limit block 2 is provided on the bottom block 1, and a first groove 21 is provided on the upper end; a first through hole 22 corresponding to the fixing structure 11 is also provided on the first limit block 2; the second limit block 3 is provided on the first limit block 2, and a second groove 31 adapted to the first groove 21 is provided on the lower end; the first groove 21 and the second groove 31 are spliced ​​to form a positioning hole 23 for accommodating a steel bar 71; the second limit block 3 is also provided with a second through hole 32 corresponding to the first through hole 22; a mounting block 41 adapted to the fixing structure 11 is provided on the lower end of the fixing rod 4, and the mounting block 41 passes through the first through hole 22 and the second through hole 32 and is installed in the fixing structure 11.

[0038] Compared with the prior art, the side formwork for the reserved exposed reinforced concrete surface provided by the present invention is as follows: the bottom block 1 is placed on one side of the concrete surface 7 with the exposed steel bar 71, the first limit block 2 is installed on the bottom block 1, and the first groove 21 is installed in cooperation with the lower semicircular surface of the steel bar 71, and then the second limit block 3 is buckled on the first limit block 2, the second groove 31 and the first groove 21 are spliced ​​with each other to form a positioning hole 23 for accommodating the steel bar 71, and the first through hole 22, the second through hole 32 and the fixing structure 11 correspond to each other, and finally the fixing rod 4 is used to pass through the first limit block 2. A through hole 22 and a second through hole 32 allow the mounting block 41 to enter the fixed structure 11, and the fixing rod 4 is rotated to clamp the mounting block 41 in the fixed structure 11. In this way, a positioning hole 23 for accommodating the steel bar 71 can be formed by splicing the first limit block 2 and the second limit block 3, without the need to open a hole of a fixed size on the template, thereby improving the versatility of the present application. At the same time, when dismantling the side form, only the first limit block 2 and the second limit block 3 are removed from the upper and lower parts of the steel bar 71 to separate the steel bar 71 from the side form without causing mutual damage.

[0039] A plurality of cushion blocks 5 of different thicknesses are provided. When the height of the steel bar 71 changes, the height of the first limit block 2 and the second limit block 3 can be changed by the cushion blocks 5. And a sealing strip 12 is attached to the upper end of the bottom block 1 or the first limit block 2 or the second limit block 3, which can not only realize the sealed connection, but also fine-tune the height of the bottom block 1, the first limit block 2, and the second limit block 3, so that the positioning hole 23 formed by the first groove 21 and the second groove 31 corresponds to the steel bar 71. When the first limit block 2 is installed so that the lower semicircular surface of the steel bar 71 cooperates with the first groove 21, the first limit block 2 can be installed horizontally from one side of the bottom block 1. The mounting block 41 is set as a long block, and the fixing structure 11 is set in an oblong hole. After the mounting block 41 enters the oblong hole, the long block is adapted to the oblong hole, and the fixing rod 4 is rotated so that the outer side surface of the long block interacts with the inner wall of the oblong hole to achieve the effect of anchoring.

[0040] See also Figures 1 to 7 As a specific implementation of the reserved exposed reinforced concrete surface side form provided by the present invention, the fixing structure 11 includes a first mounting hole 111 located at the upper end of the bottom block 1 and a second mounting hole 112 located at the lower end of the bottom block 1, the first mounting hole 111 and the second mounting hole 112 are connected, and the hole area of ​​the second mounting hole 112 is larger than the hole area of ​​the first mounting hole 111, the mounting block 41 passes through the first mounting hole 111 and enters the second mounting hole 112, the mounting block 41 successively passes through the first through hole 22, the second through hole 32, and the first mounting hole 111 to enter the second mounting hole 112, and the hole area of ​​the second mounting hole 112 is slightly larger than the hole area of ​​the first mounting hole 111, that is, the width of the second mounting hole 112 is smaller than the length of the mounting block 41, and when the fixing rod 4 is rotated, the outer side surface of the mounting block 41 interacts with the inner wall of the second mounting hole 112, so as to achieve the purpose of fixing the bottom block 1, the first limit block 2, and the second limit block 3 with the help of the fixing rod 4. At the same time, after the mounting block 41 rotates, the first mounting hole 111 limits the mounting block 41 to prevent the mounting block 41 from being separated from the second mounting hole 112 .

[0041] See also Figure 1 and Figure 2As a specific implementation method of the side formwork for reserved exposed reinforced concrete surface provided by the present invention, there are two fixing structures 11, which are evenly distributed on the bottom block 1, and there are two fixing rods 4, which correspond to the two fixing structures 11 one by one. Two fixing structures 11 are set on the bottom block 1 and are evenly distributed on both sides of the upper end surface of the bottom block 1. At the same time, two first through holes 22 are set on the first limit block 2, and two second through holes 32 are set on the second limit block 3. Therefore, after installing the bottom block 1, the first limit block 2 and the second limit block 3, two fixing rods 4 are used to pass through the second through hole 32, the first through hole 22 and the first mounting hole 111 and the second mounting hole 112 in the fixing structure 11 on the same side, so that the second limit block 3, the first limit block 2 and the bottom block 1 are fixed together, and the fixing effect is better.

Therefore, after installing the bottom block 1, according to the height size of the steel bar 71 and the thickness of the first limit block 2, one or more suitable pad blocks 5 can be pre-installed and placed on the bottom block 1, so that after installing the first limit block 2, the lower semicircular surface of the steel bar 71 can be accurately installed in the first groove 21. When there are four steel bars 71 and they are arranged in a rectangular shape, two groups of first limit blocks 2 and second limit blocks 3 are required. Therefore, one or more suitable pads 5 can be installed and placed on the second limit blocks 3 of the first group, so that the first limit blocks 2 of the second group can be accurately installed. In addition, the terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features.
