[0032] The bottom template 31 and the four side templates 32 are detachably connected, and after pouring is completed, the four side templates 32 and the bottom template 31 can be removed, so that the prefabricated column poured is exposed and taken out.

[0033] The top surface of the bottom mold plate 31 is provided with a concave-convex pattern groove (not shown in the figure), which can form a concave-convex pattern on the bottom surface of the poured prefabricated column.

[0034] In the embodiment, the number of support pieces is four, and the four support pieces are arranged near the four corners of the bottom mold plate 31 and are symmetrically distributed, which can make the prefabricated column structure stable and reliable, high in strength, and can be stably and reliably assembled and connected together between two prefabricated columns.

[0035] In the embodiment, as shown in Figure 2 The mold for making the prefabricated column further includes a limiting ring 30, which fastens the four support pieces. Specifically, the limiting ring 30 abuts against the outer wall of the sleeve 21 of the four support pieces to fasten the four support pieces, which can stably and reliably arrange the four support pieces on the bottom mold plate 31 and avoid the movement or tilting of the support pieces due to the influence of the slurry during pouring.

[0036] In the embodiment, the support pieces have no fixed connection with the mold, and the support pieces will not hinder the disassembly of the mold. The sleeve 21 can be arranged in the mold by a commonly used connection method in the art, which is not limited here.

[0037] One support piece includes at least one sleeve 21, which is not limited here.

[0038] In the embodiment, one support piece includes three sleeves 21, and the centers of the three sleeves 21 can form an isosceles triangle or an equilateral triangle, which can make the prefabricated column structure stable and reliable, high in strength, and can be stably and reliably assembled and connected together between two prefabricated columns.

[0039] The material of the sleeve 21 can be stainless steel, which is not limited here.

[0042] The fixing member can include a fixing hole (not shown in the figure) arranged through the sleeve 21 and the supporting column 22, and a fixing pin (not shown in the figure) inserted in the fixing hole, so that the supporting column 22 can be fixed and limited to avoid falling to the bottom of the sleeve 21.

[0043] In other preferred embodiments, the fixing member can also have other shapes as long as it can fix and limit the supporting column 22 to avoid falling to the bottom of the sleeve 21, which is not specifically limited here.

[0044] The sleeve 21 is communicated with a pulp inlet pipe (not shown in the figure) and a pulp outlet pipe 25, and the axial directions of the pulp inlet pipe and the pulp outlet pipe 25 are horizontal directions; and the pulp outlet pipe 25 is arranged higher than the pulp inlet pipe, that is, the pulp outlet port 24 of the pulp outlet pipe 25 is arranged higher than the pulp inlet port 23 of the pulp inlet pipe.

[0045] The pulp outlet port 24 of the pulp outlet pipe 25 and the pulp inlet port 23 of the pulp inlet pipe are in contact with the side mold plate, and the pulp outlet port 24 of the pulp outlet pipe 25 and the pulp inlet port 23 of the pulp inlet pipe are blocked by the side mold plate 32, so that the pulp can be prevented from entering the pulp outlet port 24 of the pulp outlet pipe 25 and the pulp inlet port 23 of the pulp inlet pipe during the pouring and manufacturing of the prefabricated column. After pouring is completed, the pulp outlet port 24 of the pulp outlet pipe 25 and the pulp inlet port 23 of the pulp inlet pipe are located on the side of the prefabricated column.

[0046] The observation pipe is an L-shaped integrated pipe, including a vertical observation pipe 13 and a horizontal observation pipe 14 in communication; the vertical observation pipe 13 is erected on the bottom mold plate 31, and the vertical observation pipe 13 extends upward from the bottom surface of the bottom mold plate 31, and the bottom mold plate 31 is provided with a second through hole 34 corresponding to the inlet 11 of the vertical observation pipe 13. The outlet 12 of the horizontal observation pipe 14 is in contact with the side mold plate 32, and the outlet 12 of the horizontal observation pipe 14 is higher than the pulp outlet port 24 of the pulp outlet pipe 25.

[0047] In this embodiment, the observation pipe has no fixed connection relationship with the mold plate, and the observation pipe will not hinder the disassembly of the mold plate; the observation pipe can be arranged in the mold plate by a commonly used connection method in the art, for example, the observation pipe can be connected with the limiting ring 30 or the sleeve 21, so that the observation pipe is stably arranged in the mold plate, which is not specifically limited here.

[0048] As Figures 5-10As shown, the prefabricated column of the embodiment is made of a template, which comprises a prefabricated column body 10 and a plurality of support members symmetrically arranged in the prefabricated column body 10. The bottom opening of the sleeve 21 is located on the bottom surface of the prefabricated column body 10, and the top of the support column 22 extends out of the top surface of the prefabricated column body 10. The inlet of the grout inlet pipe and the outlet of the grout outlet pipe 25 are both located on the side surface of the prefabricated column body 10, and the outlet of the grout outlet pipe 25 is higher than the inlet of the grout inlet pipe. The inlet 11 of the vertical observation pipe 13 is located on the bottom surface of the prefabricated column body 10, and the outlet 12 of the horizontal observation pipe 14 is located on the side surface of the prefabricated column body 10, and the outlet 12 of the horizontal observation pipe 14 is higher than the outlet of the grout outlet pipe 25.

[0049] In the embodiment, the prefabricated column body 10 formed by pouring is a cuboid structure, and the bottom surface of the prefabricated column body 10 is formed with uneven patterns. When assembling and connecting two adjacent prefabricated columns, grout is filled between the two adjacent prefabricated columns to achieve bonding connection of the two adjacent prefabricated columns. By forming uneven patterns on the bottom surface of the prefabricated column body 10, the bonding connection between the patterns and the grout can be strengthened, so that the two adjacent prefabricated columns can be firmly and reliably assembled and connected together.

[0050] The number of support members is four, and the four support members are located inside the prefabricated column body 10 and close to the four corners of the prefabricated column body 10, respectively.

[0051] By arranging the support members at the four corners of the prefabricated column body 10, respectively, the prefabricated column body structure can be stable and reliable, and has high strength. The assembly strength and connection strength between the two adjacent prefabricated columns can be strengthened, so that the two adjacent prefabricated columns can be firmly and reliably assembled and connected together.

[0052] Each support member comprises three sleeves 21, and the centers of the three sleeves 21 can be connected to form an isosceles triangle or an equilateral triangle, i.e. the three sleeves 21 are symmetrically distributed, so that the prefabricated column body structure can be stable and reliable, and has high strength.

[0053] The top of the support column 22 extends out of the top surface of the prefabricated column body 10, and the bottom of the support column 22 has a gap h with the bottom surface of the prefabricated column body 10, i.e. the support column 22 does not extend to the bottom of the sleeve 21, and there is still a gap at the bottom of the sleeve 21. When two prefabricated columns above and below are assembled and connected, the top of the support column 22 of the prefabricated column below can be inserted into the sleeve 21 of the prefabricated column above, so that the assembly and connection of the two prefabricated columns above and below can be achieved.

[0054] The process of assembling and connecting the two prefabricated columns comprises: abutting the two prefabricated columns, the two prefabricated columns are arranged in an upper-lower manner, wherein the top of the support column 22 of the lower prefabricated column is inserted into the sleeve 21 of the upper prefabricated column; a plurality of shims 15 are inserted between the upper and lower prefabricated columns (between the bottom surface of the upper prefabricated column and the top surface of the lower prefabricated column) to form a leveling gap between the upper and lower prefabricated columns, so as to facilitate leveling of the prefabricated columns; then a circle of sealing grouting material is applied to the outer edge between the upper and lower prefabricated columns, so that the leveling gap between the upper and lower prefabricated columns forms a closed cavity. Then grouting is carried out, grouting material is injected from the grouting inlet 23 of the grouting pipe, and the grouting material injected into the sleeve 21 flows downward first and then flows into the leveling gap between the upper and lower prefabricated columns; after the leveling gap is filled with grouting material, the part of the continuously injected grouting material enters the inlet 11 of the vertical observation pipe 13 and then flows out from the outlet 12 of the horizontal observation pipe 14; at the same time, the part of the continuously injected grouting material moves upward in the sleeve 21, fills the sleeve 21, and then flows out from the grouting outlet 24 of the grouting outlet pipe 25. Since the outlet 12 of the horizontal observation pipe 14 is higher than the grouting outlet 24 of the grouting outlet pipe 25, the grouting outlet 24 of the grouting outlet pipe 25 flows out first, and the outlet 12 of the horizontal observation pipe 14 flows out later; when the outlet 12 of the horizontal observation pipe 14 flows out, it indicates that the grouting operation is completed. Stop grouting, and then seal all the outlets and inlets with rubber plugs.

[0055] In the embodiment, the inlets 23 of the grouting pipes are at the same height, so that the grouting operation can be facilitated.

[0056] In the embodiment, the grouting outlet 24 of the grouting outlet pipe 25 is higher than the grouting inlet of the grouting pipe, and the grouting material moves upward in the sleeve 21, so that the gaps in the sleeve 21 can be filled with grouting material, and the support column 22 can be firmly and reliably inserted and fixed in the sleeve 21, so that the two adjacent prefabricated columns can be firmly and reliably abutted and assembled together.

[0057] In the embodiment, the distance m between the outlet 12 of the horizontal observation pipe 14 and the grouting outlet 24 of the grouting outlet pipe 25 is 8-20 mm, and preferably 10 mm. That is, the outlet 12 of the horizontal observation pipe 14 is 10 mm higher than the grouting outlet 24 of the grouting outlet pipe 25, which can ensure that the leveling gap between the upper and lower prefabricated columns can be filled with grouting material and grouted densely, and the sleeve 21 can be filled with grouting material and grouted densely, so that the two prefabricated columns can be firmly and reliably assembled and connected together.

[0058] In the embodiment, the plurality of shims 15 can be distributed along the edges of the leveling gap at equal intervals to seal the four sides of the leveling gap, and the gaps are filled with grouting material to connect the upper and lower prefabricated columns, so that the leveling gap between the upper and lower prefabricated columns forms a closed cavity, and grouting construction can be carried out after the grouting material solidifies.

[0059] In the embodiment, the height t of the leveling gap is the thickness of the cushion block 15, which can be 15-25mm, preferably 20mm, without specific limitation.

[0060] In the embodiment, the height n of the top of the support column 22 protruding from the top surface of the prefabricated column body 10 is greater than the height t of the leveling gap, so that the top of the support column 22 of the lower prefabricated column can pass through the leveling gap and be inserted into the sleeve 21 of the upper prefabricated column, realizing the splicing of the two prefabricated columns.

[0061] In the embodiment, the distance h between the bottom of the support column 22 and the bottom surface of the prefabricated column body 10 plus the height t of the leveling gap is greater than the height n of the top of the support column 22 protruding from the top surface of the prefabricated column body 10, i.e. h+t is greater than n. Thus, the distance s between the upper and lower support columns 22 can be formed, the slurry can fill the leveling gap between the upper and lower support columns 22, and the grouting is compact, so that the upper and lower support columns 22 can be bonded and fixed together, thereby strengthening the firm and reliable assembly connection of the upper and lower prefabricated columns.

[0062] The prefabricated column structure of the embodiment is stable and reliable, has high strength, can realize butt joint assembly conveniently and quickly, and can realize stable and reliable assembly butt joint between adjacent two prefabricated columns.

[0063] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features thereof.
