[0003] At present, the construction of exposed concrete walls mostly adopts the layered pouring method from bottom to top. However, this method is prone to cause obvious stratification of the decorative surfaces on the opposite sides of the wall due to the difference in the proportion of pouring materials and the interval of construction time, which affects the pouring effect of exposed concrete.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-10 This application is described in further detail.

[0028] Embodiment 1: The embodiment of the present application discloses a plain concrete splicing template. The plain concrete splicing template is overlapped on one side of the existing wall and is located between the ground and the ceiling. Figure 1 The plain concrete splicing formwork comprises an outer formwork mechanism and an inner formwork mechanism, and the inner formwork mechanism is arranged in the outer formwork mechanism.

[0029] Reference Figure 1 The outer mold mechanism includes an outer mold group 1 and a side mold 2. The outer mold group 1 has two groups, and the two groups of outer mold groups 1 are opposite to each other. After the wall is cast, the surface opposite to the outer mold group 1 is the decorative surface of the wall. Each group of outer mold groups 1 has at least one outer mold plate 101. In this embodiment, the number of outer mold plates 101 in each group is one; in other embodiments, the number of outer mold plates 101 in each group can be two, three, etc., and two adjacent outer mold plates 101 in the same group are spliced ​​with each other.

[0030] Reference Figure 1 and Figure 2 , one end of the outer formwork 101 abuts against the existing wall, and the outer formwork 101 of the two groups of outer formworks 1 have the same extension length and are parallel to each other. The side formwork 2 is detachably connected to the end of the two groups of outer formworks 101 away from the existing wall to close the end of the outer formwork 101 away from the existing wall, and the outer formwork 101 and the side formwork 2 together enclose a space for pouring concrete. Specifically, in this embodiment, the side formwork 2 and the two groups of outer formworks 101 have a plurality of through holes 28 vertically opened on opposite sides thereof, and the end wall of the outer formwork 101 has threaded holes corresponding to the through holes 28 one by one, and the side formwork 2 is installed by passing the bolt rod through the through holes 28 and threading it into the outer formwork 101.

[0031] Reference Figure 2 and Figure 3 The inner mold mechanism includes an inner mold group 3 and a connecting member 4. The inner mold group 3 has two groups. Each group of inner mold groups 3 has at least one inner mold plate 301, and the lengths of the inner mold plates 301 in the two inner mold groups 3 are the same. The bottom ends of the inner mold plates 301 of the two groups of inner mold groups 3 are connected to the connecting member 4, and the connecting member 4 is located in the middle of the two outer mold plates 101; and the top ends of the inner mold groups 3 are respectively abutted against the two opposite groups of outer mold plates 101 and close to the top ends of the outer mold plates 101, so that the two groups of inner mold plates 301 separate the casting space between the two outer mold plates 101 into a first casting cavity 5 and a second casting cavity 6. The first casting cavity 5 is formed on the outer wall of the inner mold plate 301 on one side close to the outer mold plate 101, between the inner wall of the outer mold plate 101 and the ground, and the second casting cavity 6 is formed on the outer wall of the inner mold plate 301 on one side away from the outer mold plate 101, between the inner wall of the outer mold plate 101 and the ceiling.

[0032] In this embodiment, each group of inner modules 3 has one inner template 301 . In other embodiments, each group of inner modules 3 may have two or three inner templates 301 . The inner templates 301 in each group of inner modules 3 are abutted in sequence along the length direction of the outer template 101 .

[0033] Reference Figure 1 and Figure 2 When pouring, the first pouring cavity 5 is poured first. After the clear water concrete in the first pouring cavity 5 is initially set, the side formwork 2 and the inner formwork 301 are removed. After that, the side formwork 2 is reconnected to the outer formwork 101, and then the second pouring cavity 6 is poured. By pouring the wall in two steps, the single pouring amount of the wall is reduced, the concrete is more stable, and the dividing line of the layer is located at the top of the wall decoration surface, which reduces the obvious degree of layering of the wall decoration surface.

[0034] Reference Figure 4 and Figure 5 , wherein the connecting member 4 includes a central shaft 41, an abutment disk 42 and a limiting sleeve 43. The central shaft 41 is in the shape of a circular shaft, the abutment disk 42 is in the shape of a circular disk and is coaxially fixed to one end of the central shaft 41, and the end of the central shaft 41 away from the abutment disk 42 has an external thread. The limiting sleeve 43 is coaxially sleeved on the outer wall of the central shaft 41 and can move along the axial direction of the central shaft 41. Specifically, a guide bar 29 protruding from the inner wall of the limiting sleeve 43 is fixed on the inner wall of the limiting sleeve 43, and a guide groove 30 for the guide bar 29 to slide is opened on the outer wall of the central shaft 41 along its own axial direction, and the guide groove 30 passes through the end of the central shaft 41 away from the abutment disk 42, so that the limiting sleeve 43 can be disassembled from the end of the central shaft 41 away from the abutment disk 42. The outer diameter of the limiting sleeve 43 is smaller than the outer diameter of the abutment disk 42, so that the limiting sleeve 43 is moved on the central shaft 41 to abut against the abutment disk 42 and then positioned relative to the central shaft 41, and the total extension length of the single set of outer templates 101, the extension length of the single set of inner templates 301, and the extension length of the limiting sleeve 43 and the abutment disk 42 are all consistent. Reference Figure 4 and Figure 5The bottom end of the inner template 301 has a connecting sleeve 7 for sleeve-mounting the limiting sleeve 43, so as to connect the inner template 301 with the connecting sleeve 7. The connecting sleeve 7 is cylindrical, and the extension length of the connecting sleeve 7 is half of the extension length of the inner template 301, and the connecting sleeve 7 is fixed at the half position of the inner template 301. Specifically, the outer wall of the limiting sleeve 43 is evenly spaced and fixed with a plurality of limiting keys 8 along its own circumference, and the extension length of each limiting key 8 is consistent with the extension length of the limiting sleeve 43. The inner wall of the connecting sleeve 7 is provided with limiting grooves 9 corresponding to the limiting keys 8, and the limiting grooves 9 are used for the limiting keys 8 to be inserted, so as to limit the relative rotation between the connecting sleeve 7 and the limiting sleeve 43 when the limiting sleeve 43 is sleeved on the connecting sleeve 7. The matching angles between the inner formwork 301 and the limiting sleeve 43 in the same group are consistent, and an included angle is formed between the two groups of inner formworks 301. The included angle between the two groups of inner formworks 301 is adjusted by the matching angle between the connecting sleeve 7 and the limiting sleeve 43, thereby adjusting the casting thickness of the wall.

[0035] Reference Figure 4 and Figure 5 , the outer diameter of the connecting sleeve 7 is larger than the outer diameter of the abutment disk 42, and one end of the connecting sleeve 7 flush with the end of the inner template 301 is provided with a first countersunk groove 10 for the abutment disk 42 to abut. When the inner template 301 cooperates with the limiting sleeve 43, if there are multiple inner templates 301 in the same group, the inner templates 301 in the same group are abutted in sequence along the axial direction of the central axis 41, and the connecting sleeves 7 of the two groups of inner templates 301 are alternately sleeved on the limiting sleeve 43 and abutted alternately in sequence. The abutment disk 42, the end of the inner template 301 flush with the abutment disk 42, and the end of the limiting sleeve 43 flush with the abutment disk 42 are all abutted against the existing wall. In addition, after the abutment disk 42 is abutted into the first countersunk groove 10, the end of the central axis 41 away from the abutment disk 42 is passed through the end of the inner template 301 away from the first countersunk groove 10.

[0036] Reference Figure 2 and Figure 6 The end of the inner template 301 away from the connecting sleeve 7 is fixed with an abutting tube 12, which is cylindrical, and the axis of the abutting tube 12 is flush with the axis of the connecting sleeve 7, and the extension length of the abutting tube 12 is consistent with the extension length of the inner template 301, and the two ends of the abutting tube 12 that are away from each other are respectively flush with the two ends of the inner template 301 that are away from each other. The inner wall of the outer template 101 facing the casting space is provided with an arc groove 13 for the abutting tube 12 to abut, and the arc groove 13 is close to the top of the outer template 101 and is used to support the abutting tube 12 of the inner template 301.

[0037] Reference Figure 4 and Figure 5, a same connecting shaft 15 is coaxially slidably penetrated in the abutting tube 12 of the inner template 301 (a single inner template 301 in this embodiment) in the same group. An abutting disc 16 is fixed at the end of the connecting shaft 15. The abutting disc 16 is in the shape of a disc with an outer diameter larger than the outer diameter of the connecting shaft 15 and smaller than the outer diameter of the abutting tube 12. The abutting disc 16 is coaxially arranged with the connecting shaft 15. A second countersunk groove 17 is provided on the end wall of the inner template 301 for the abutting disc 16 to abut against so that the surface of the abutting disc 16 away from the connecting shaft 15 is flush with the end wall of the inner template 301.

[0038] Reference Figure 1 and Figure 4 , after the abutment tube 12 is sleeved with the connecting shaft 15 and spliced ​​with the abutment disk 16, the end of the connecting shaft 15 extending away from the abutment disk 16 abuts the end of the tube 12. The side formwork 2 is provided with a through hole 31 for the connecting shaft 15 and the center shaft 41 to pass through, so as to further limit the position of the inner formwork 301 through the side formwork 2. The connecting shaft 15 and the center shaft 41 are both threadedly matched with a locking piece 11, and the locking piece 11 is in the shape of a nut. After the connecting shaft 15 and the center shaft 41 pass through the side formwork 2, a plurality of locking pieces 11 are threadedly sleeved on the corresponding connecting shafts 15 and the center shaft 41, and the locking pieces 11 are simultaneously pressed against the outer wall of the side formwork 2 away from the casting space to further lock the side formwork 2.

[0039] Reference Figure 3 and Figure 6 Furthermore, the lower half of the arc groove 13 is in the shape of an arc coaxial with the abutment tube 12, the upper half of the arc groove 13 is a non-circular curve, and the curvature radius of the upper half of the arc groove 13 is greater than the curvature radius of the lower half of the arc groove 13, so that when the inner template 301 rotates inward around the axis of the central axis 41, the abutment tube 12 can move out of the arc groove 13 in the upper half of the tube arc groove 13.

[0040] Reference Figure 1 and Figure 2 Therefore, when disassembling the inner template 301, first remove the side template 2, then take out the limiting sleeve 43 away from the existing wall, and then rotate the inner template 301 inward around the axis of the central axis 41 to separate the outer wall of the inner template 301 from the casting surface, and then take out the inner template 301 away from the existing wall, so as to reduce the difficulty of demoulding and taking out the inner template 301. A pull ring (not shown in the figure) is embedded at the end of the limiting sleeve 43 to facilitate pulling out the limiting sleeve 43.

[0041] Reference Figure 6 and Figure 7In order to limit the concrete from entering the arc groove 13 during the secondary pouring, the outer mold group 1 is plugged with a blocking strip 14 at the arc groove 13. The extension length of the blocking strip 14 is consistent with the extension length of the inner mold 301 of the same group, and the cross-sectional size of the blocking strip 14 is consistent with the cross-sectional size of the arc groove 13. The blocking strip 14 is plugged into the arc groove 13 along the length direction of the outer mold 101, so that the arc groove 13 is filled when the outer mold 101 is poured for the secondary pouring, that is, the inner wall of the outer mold 101 is flush with the upper and lower walls when the secondary pouring is carried out.

[0042] In addition, an inserting strip 18 is fixed on the outer wall of the blocking strip 14. The inserting strip 18 extends together with the blocking strip 14, and the longitudinal section of the inserting strip 18 is dovetail-shaped with a width gradually increasing in the direction away from the blocking strip 14. The outer template 101 has a slot 19 on the inner wall of the arc groove 13 for inserting the inserting strip 18. The slot 19 extends along the arc groove 13. By inserting the inserting strip 18 into the slot 19, the rotation between the blocking strip 14 and the outer template 101 can be restricted, thereby improving the stability of the blocking strip 14.

[0043] Reference Figure 1 and Figure 7 Furthermore, an extension rod 20 is provided at one end of the blocking strip 14 away from the existing wall, and the length extension direction of the extension rod 20 is parallel to the length extension direction of the blocking strip 14. The outer wall of the extension rod 20 has an external thread, and a hole for the extension rod 20 to pass through is provided on the side formwork 2. After the extension rod 20 passes through the side formwork, a threaded connection nut can be used to lock the extension rod 20 and the side formwork 2.

[0044] Reference Figure 1 In addition, a grouting port 32 communicating with the first pouring cavity 5 is provided at the bottom of the side formwork 2, and grout outlets 33 communicating with the first pouring cavity 5 are provided at opposite sides of the top of the side formwork 2. When pouring once, concrete is injected through the grouting port 32, and the concrete pouring condition is observed through the grout outlet 33. When concrete overflows, the grout outlet 33 and the grout inlet are blocked with a plug. When pouring twice, the through hole 31 through which the central shaft 41 passes is used as the grouting inlet, and the through hole 31 through which the connecting shaft 15 passes is used as the grout outlet, and the through hole 31 is blocked with a plug when concrete overflows.
