[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0029] Example 1

[0030] like Figure 1-Figure 3 As shown, a cavity multi-rib wall core mold connector, the cross-section of the connector is a symmetrical structure, including a left connecting plate 1 and a right connecting plate 2, one side of the left connecting plate 1 and the right connecting plate 2 are connected to each other to form a support portion 3, and the left connecting plate 1 and the right connecting plate 2 are away from the end of the support portion 3 to form a movable portion 4, and the movable portion 4 is preferably set as an opening, and the size of the opening can be changed; the left connecting plate 1 includes a left front limit plate 11 and a left rear limit plate 12, and one side of the left front limit plate 11 and the left rear limit plate 12 is connected by a left groove The plates 13 are connected to each other, and the left front limit plate 11, the left rear limit plate 12 and the left groove plate 13 form a left card slot 14; the right connecting plate 2 includes a right front limit plate 21 and a right rear limit plate 22, and one side of the right front limit plate 21 and the right rear limit plate 22 are connected to each other through the right groove plate 23, and the right front limit plate 21, the right rear limit plate 22 and the right groove plate 23 form a right card slot 24; the left card slot 14 and the right card slot 24 are used to limit the relative positions of adjacent cavity dense rib wall core molds to avoid relative movement.

[0031] In this embodiment, the left front limit plate 11 and the left rear limit plate 12 are parallel to each other, the right front limit plate 21 and the right rear limit plate 22 are parallel to each other, the plate surfaces of the left front limit plate 11 and the right front limit plate 21 are located in the same plane, and the plate surfaces of the left rear limit plate 12 and the right rear limit plate 22 are located in the same plane, so that the connecting part is in more complete contact with the surface of the cavity dense rib wall core mold, thereby increasing the support and improving the stability of the connection of the connecting part.

[0032] In this embodiment, the groove width of the left groove 14 and the right groove 24 is not less than twice the thickness of the cavity dense rib wall core mold, so that the adjacent cavity dense rib wall core molds at the connection of the connecting piece are confined within the left groove 14 and the right groove 24 to avoid the connection from falling off; in another embodiment, the groove width of the left groove 14 and the right groove 24 is set according to the distance between the adjacent cavity dense rib wall core molds at the connection of the connecting piece. For example, when a partition is provided between adjacent cavity dense rib wall core molds, the groove width of the left groove 14 and the right groove 24 is the sum of the thickness of the partition and twice the thickness of the cavity dense rib wall core mold, so as to adapt to the cavity dense rib wall with different construction requirements and improve practicality.

[0033] In this embodiment, the side of the left rear limit plate 12 away from the left front limit plate 11 is connected to the left support plate 15, and the side of the right rear limit plate 22 away from the right front limit plate 21 is connected to the right support plate 25. The left support plate 15 and the right support plate 25 are interconnected to form a support part 3. The cross-sectional shape of the left support plate 15 and the right support plate 25 can be optionally set to an arc or a straight plate type, so that the cross-sectional shape of the support part 3 is U-shaped or triangular. The U-shape makes the support part 3 more evenly stressed when the connecting piece is in use, avoiding stress concentration; the triangle reduces the amount of material used in the manufacture of the connecting piece, and is more economical.

[0034] In this embodiment, the connecting part is made of an elastic metal material or plastic material by integral molding, which has better integrity and stability. The elasticity is mainly used in the support part 3. The opening size of the movable part 4 is changed by squeezing the left support plate 15 and the right support plate 25 toward each other, and it returns to the initial state when there is no force.

[0035] In another embodiment, an extrusion portion 5 is provided on the outer plate surfaces of the left support plate 15 and the right support plate 25 to increase the contact area when construction workers operate the connecting parts. Preferably, the extrusion portion 5 is a stepped protrusion provided on the outer plate surfaces of the left support plate 15 and the right support plate 25, and a serrated texture is provided on the outer side of the stepped protrusion to increase the friction with the construction workers, making it faster and more convenient to use, avoiding slipping, and improving construction efficiency.

[0036] In this embodiment, an elastic member 6 is further included, which is arranged between the left connecting plate 1 and the right connecting plate 2. Preferably, the elastic member 6 is a spring, which is economical. The two ends of the spring are respectively arranged on the left connecting plate 1 and the right connecting plate 2. The spring is squeezed by the relative movement of the left connecting plate 1 and the right connecting plate 2, and the left connecting plate 1 and the right connecting plate 2 are restored to their initial positions after the connecting member is no longer subjected to force, thereby improving the stability of the connecting member support.

[0037] Example 2

[0038] like Figure 4-Figure 7 As shown, a cavity dense rib wall body includes the connecting parts mentioned above, and also includes a top keel and a ground keel. The top keel is set at the ceiling or the top of the floor through connecting nails, and the ground keel is set at the bottom of the floor through grounding bolts. A cavity dense rib wall core model material 7 is set between the top keel and the ground keel. A plurality of connecting holes 8 are evenly opened on the cavity dense rib wall core model material 7. The cavity dense rib wall core model materials 7 are relatively arranged to form a whole, and the two connecting holes 8 are correspondingly overlapped. The connecting parts are clamped in the connecting holes 8 of the relative cavity dense rib wall core model materials 7. The connecting holes 8 are set as long strip through holes. The length of the connecting holes 8 is consistent with the length of the connecting parts to avoid relative sliding of the relative cavity dense rib wall core model materials 7. A reinforcement layer 9 is set on the outside of the cavity dense rib wall core model material 7 to enhance the stability of the wall.

[0039] In an optional embodiment, the reinforcement layer 9 includes a premixed mortar layer 91 contacting the surface of the cavity dense rib wall core model material 7, a plastering layer 92 covering the premixed mortar layer 91, and a cloth layer 93 covering the plastering layer 92. A galvanized welded wire mesh 94 is further provided in the premixed mortar layer 91 to enhance the integrity. Specifically, the galvanized welded wire mesh 94 is provided on the outer surface of the connected cavity dense rib wall core model material 7, and then the mixed M15 cement mortar is sprayed on the cavity dense rib wall core model material 7. The grooves on the outside of the model material 7 are filled, and the sprayed surface is roughened after spraying to form a premixed mortar layer 91, and the grooves on the outside of the cavity dense rib wall core model material 7 are filled with mortar. The galvanized welded wire mesh 94 is located in the premixed mortar layer 91, and then M10 cement mixed mortar or homogeneous mastic material is used for plastering to form a plastering layer 92, and then the alkali-resistant glass fiber mesh is arranged on the surface of the plastering layer 92 to form a cloth layer 93, thereby improving the integrity of the wall.

[0040] In an optional embodiment, a filling plate 10 is further provided between the relative cavity dense-rib wall core model materials 7. The filling plate 10 is made of foam board and is used to improve the sound insulation, heat preservation and other effects of the wall. A through hole is opened through the filling plate 10 at the position corresponding to the connection hole 8 to facilitate the through connection of the connecting piece, thereby improving the stability of the wall.

[0041] In an optional embodiment, the sum of the widths of the left front limit plate 11 and the right front limit plate 21 of the connecting member is no greater than the width of the connecting hole 8, so as to facilitate the insertion of the connecting member into the connecting hole 8 and improve the construction efficiency, and the initial distance between the left groove plate 13 and the right groove plate 23 is the same as the width of the connecting hole 8, so that when the connecting member is inserted into the connecting hole 8 and restored to the initial state, the left card slot 14 and the right card slot 24 can contact the side edges of the connecting hole 8, avoiding relative displacement of the cavity dense rib wall core model material 7 to the left and right, thereby improving the stability and safety of the use of the connecting member.

[0042] When in use, the cavity dense rib wall core model materials 7 are relatively merged, and the connection holes 8 on them are overlapped, and then the connection pieces corresponding to the number of connection holes 8 are taken. The construction personnel can press the extrusion part 5 on the connection piece by hand to make the opening of the movable part 4 smaller until it can be inserted into the connection hole 8. Then, the end of the connection piece away from the support part 3 is inserted into and passes through the overlapping connection holes 8, and the connection piece is released so that the left card slot 14 and the right card slot 24 of the connection piece can be clamped on both sides of the connection hole 8, and the connection piece is connected to the connection holes 8 one by one. The connecting pieces can be inserted in opposite directions at intervals left and right, and up and down, to further improve the stability of the connection of the cavity dense rib wall core mold material 7. For walls that require filling plates 10, the filling plates 10 are first clamped between the opposite cavity dense rib wall core mold materials 7 before connection. After the connection is completed, the galvanized welded wire mesh 94 is set on the outer surface of the profile, and then cement mortar is sprayed on the outer surface of the profile to form a premixed mortar layer 91. A plaster layer 92 and a cloth layer 93 are arranged layer by layer on the premixed mortar layer 91, thereby improving the stability and service life of the wall.
