[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. It should be noted that, in order to facilitate description, in the present application, "left side" is "first end", "right side" is "second end", "upper side" is "first end", and "lower side" is "second end" in the current view. The purpose of such description is to clearly express the technical solutions, and should not be understood as improper limitation on the technical solutions of the present application.
[0034] The present application solves the technical problem that the existing shear groove is prone to deviation and deformation, resulting in low construction efficiency, and provides a shear groove quick-release mold for a steel structure column foot, which is characterized in that a mold box 10 is arranged, the mold box 10 has a bottom surface 101 and a side wall 102, and a first end of the mold box 10 forms an opening 103; at the opening 103, adjacent side walls 102 are supported and arranged with arrangement positions 104;
[0035] A threaded connecting piece 20 is arranged on each arrangement position 104, and a single-end bolt 30 can be connected to each threaded connecting piece 20;
[0036] The technical solution has the technical advantages that the threaded connecting piece 20 and the inner corner of the mold box 10, i.e., the arrangement position 104, are arranged with a positioning point, so that the position of the mold box 10 that is most prone to deformation has a support and anti-deformation function. Specifically, the single-end bolt 30 cooperates with the threaded connecting piece 20 to balance the pouring pressure generated at the arrangement position 104 during the pouring process, so as to ensure the stability of the mold box 10, thereby forming a stable shear groove. When disassembling, the single-end bolt 30 can be loosened, or the single-end bolt 30 is used as a disassembly force point to cooperate with the disassembly of the mold box 10, so that the technical solution has the technical advantages of stable use and rapid disassembly.
[0037] The mold quick release is usually reflected in the stage of separating the shear groove mold from the concrete after the short column head concrete pouring is completed, and the shear groove is formed by using the quick-release bolt connection mode, so as to take out the product and perform the next round of production.
[0038] The prefabrication and use process is as follows:
[0039] (1) Designing the mold: according to the size requirements of the shear groove, the size of the mold box 10 is designed, and the size of each part of the mold is determined;
[0040] (2) After the mold is completed, before each concrete pouring, the shear groove quick-release mold of the steel column foot is fixed according to the design drawing position, and then the concrete is poured. When the concrete strength reaches the demolding condition, it is taken out from the shear groove. This shear groove quick-release mold of the steel column foot avoids many shortcomings of traditional wooden molds, such as: it is difficult to process and fix the wooden mold for small shear groove size, the wooden mold is insufficient in strength, the wooden mold has few turnovers, and the wooden mold is difficult to demold.
[0041] (3) The main function of the single-head bolt 30 is to become a supporting rib of the adjacent side wall 102, tightly connecting two adjacent vertical side walls 102 together, ensuring the relative position of each part unchanged when the mold box 10 bears the pressure and impact force during the concrete pouring process, preventing the mold from deforming, shifting and other problems, ensuring the overall structural stability of the mold, and thus ensuring the forming precision of the concrete short column shear groove.
[0042] In a specific embodiment, please refer to Figures 1-4 As shown in the figure, the threaded connection piece 20 includes two groups of upper and lower arranged hexagonal nuts 21; the threaded holes of the hexagonal nuts 21 of each group of threaded connection pieces 20 are coaxially arranged; a preset gap 201 is formed between the upper and lower arranged two groups of hexagonal nuts 21.
[0043] In a specific embodiment 1, please refer to Figure 3 As shown in the figure, the hexagonal nut 21 is welded on the side wall 102.
[0044] In a specific embodiment 2, please refer to Figure 4 As shown in the figure, the arrangement position 104 is welded with a welded connecting block 210;
[0045] The radial welding connection of the hexagonal nut 21 is on the welded connecting block 210.
[0046] In a specific embodiment, please refer to Figures 1-4 As shown in the figure, the length and width of the bottom surface 101 and the side wall 102 are the same, and the maximum length of the screw rod of the single-head bolt 30 is 1 / 2 of the height of the side wall 102.
[0047] In a specific embodiment, please refer to Figures 1-4 As shown in the figure, the bottom surface 101 and the side wall 102 are made of a steel plate with a thickness of 3mm.
[0048] In a specific embodiment, please refer to Figure 2As shown, the bottom surface 101 is provided with positioning threaded holes 11, and positioning threaded bolts 12 are screwed on the positioning threaded holes 11. Whether this set of positioning threaded bolts 12 is configured or not can be determined according to actual conditions, for example, when the pouring amount is large and the formwork removal time is long, the positioning threaded bolts 12 can be configured according to needs.
[0049] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation on the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and cannot be exhausted.
