[0099] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0100] Example 1 Steel bar connector 1

[0101] like Figure 1-11 As shown, the steel bar connector 1 includes a sheet-shaped connecting portion 11, the connecting portion 11 is provided with at least one through hole, and both ends of the connecting portion 11 are integrally connected with a sheet-shaped bending portion 12, and the bending portion 12 has a length that is bent and wrapped around the steel bar. "The length that is bent and wrapped around the steel bar" means that when the bending portion 12 is wrapped around the steel bar, the steel bar connector 1 will not fall off the steel bar.

[0102] The connecting portion 11 and the bending portion 12 are formed by bending a sheet metal material in one piece. In order to increase its rigidity and prevent the connecting portion 11 from bending, reinforcing folding edges 13 are provided on both sides of the connecting portion 11.

[0103] A specific example is that the bending portion 12 extends from the end of the connecting portion 11 and is perpendicular to the plane of the connecting portion 11, and then bends to form a U-shape. The direction of the U-shaped opening 121 is perpendicular to the plane of the connecting portion 11, and the size of the U-shape is consistent with the size of the steel bar. During installation, since the direction of the U-shaped opening 121 is perpendicular to the plane of the connecting portion 11, it is easy to buckle the two U-shaped openings 121 on two parallel steel bars, and then use external force to bend the end of the bending portion 12 to wrap around the steel bar, and the pinning state is as shown in FIG. Figure 7 , 8 shown.

[0104] As an example, the bending portion 12 includes two bending pieces 122, and there is a gap between the two bending pieces 122 that can pass through the steel bar. The gap includes a first gap section 123 and a second gap section 124, the first gap section 123 is located between the two bending pieces 122, and the second gap section 124 extends from the first gap section 123 to the end of the connecting portion 11, and the second gap section can accommodate the steel bar. Dividing the bending portion 12 into two bending pieces 122, on the one hand, makes bending more labor-saving, and on the other hand, the gap between the two bending pieces 122 can pass through the steel bar, and can connect the intersection of two longitudinal and transverse steel bars.

[0105] like Figure 1-3 As shown, as application example 1, the steel bar connector 1 is a steel mesh connector, which is provided with at least one weight-reducing hole 113 on the connecting portion 11, which can reduce weight and facilitate the passage of concrete during pouring. The figure shows that the weight-reducing holes 113 are four elliptical holes.

[0106] like Figure 9-11 As shown in the figure, as application example 2, the steel bar connector 1 is a steel bar positioning member, and a screw fixing hole 111 is provided in the middle of the connecting portion 11 for fixing on the positioning screw 2 of the screw positioning member. The connecting portion 11 is also provided with a weight reduction hole 113, and the figure shows that two elliptical holes are provided on both sides of the screw fixing hole 111.

[0107] like Figure 4-8 As shown in the figure, as application example 3, the steel bar connector 1 is a plug-in connector, wherein a plug-in hole 112 is provided in the middle of the connecting portion 11, which can be set to an elliptical shape to facilitate plugging. A weight-reducing hole 113 is also provided on the connecting portion 11, and two elliptical holes are provided on both sides of the plug-in hole 112 as shown in the figure.

[0108] Example 2 Screw Positioning Part

[0109] like Figure 12-15 As shown, the screw positioning member includes a positioning screw 2, and both ends of the positioning screw 2 have threaded ends 21; in at least one steel bar positioning member of embodiment 1, the positioning screw 2 passes through a screw fixing hole 111.

[0110] A water stop 22 is provided on the positioning screw 2 to play the role of water stopping and fixing.

[0111] The threaded ends 21 at both ends of the positioning screw 2 are sleeved with positioning caps 23, and the positioning caps 23 are made of elastic material. The positioning caps 23 are cylindrical or tapered from the outer end to the inner end, and the purpose is to form a smooth surface on the outer side of the positioning caps 23, so as to avoid or reduce damage to the concrete layer that has not been completely set when the positioning caps 23 are removed from the threaded ends 21. The axis of the positioning caps 23 can be provided with threaded holes or unthreaded holes. After removing the positioning caps 23, a pit is formed on the surface of the concrete, and the threaded end 21 is located in the pit. The pit and the threaded end 21 are used to combine the screw sleeve to hang the keel, decorative panels, etc.

[0112] Example 3 Steel Mesh Connection Structure

[0113] like Figure 19-20 As shown, the steel mesh connection structure, the steel mesh 3 is composed of transverse steel bars 31 and longitudinal steel bars 32, and also includes the steel bar connector 1 of Example 1, and the connection method is:

[0115] (2) The bent portion 12 is connected between two transverse steel bars 31 or between two longitudinal steel bars 32 of two different and parallel steel meshes 3, and the bent portion 12 is bent and wrapped around the transverse steel bars 31 or the longitudinal steel bars 32;

[0116] (3) The bending portion 12 is connected between the intersections of two transverse steel bars 31 and two longitudinal steel bars 32 of two different and parallel steel mesh sheets 3, and the two bending pieces 122 of the bending portion 12 are bent and wrapped around one of the transverse steel bars 31 or the longitudinal steel bars 32, and the gap between the outer ends of the bending pieces 122 accommodates the other of the transverse steel bars 31 or the longitudinal steel bars 32;

[0117] (4) The bending portion 12 is connected between the intersections of two transverse steel bars 31 and two longitudinal steel bars 32 of two different and parallel steel mesh sheets 3. One of the transverse steel bars 31 or the longitudinal steel bars 32 moves to the second gap section 124 through the first gap section 123. The two bending pieces 122 are bent and wrapped around the other of the transverse steel bars 31 or the longitudinal steel bars 32, so that one of the transverse steel bars 31 or the longitudinal steel bars 32 is accommodated in the second gap section 124.

[0118] Example 4: Built-in tension screw steel grid

[0119] like Figure 16-20 As shown, it includes two inner and outer steel meshes 3, and multiple screw positioning members of embodiment 2 (including multiple positioning screws 2, multiple steel positioning members).

[0123] The built-in tension screw steel mesh frame of Example 4 is arranged in the concrete layer, wherein the edge of the positioning cap 23 is flush with the front and rear plane 41. When the positioning cap 23 is removed and a pit is formed on the front and rear plane 41, at least a part of the threaded end 21 is located in the pit, and the end of the threaded end 21 is flush with the front and rear plane 41 or does not exceed the front and rear plane 41.

[0124] The steel mesh connection structure of Example 3 is also provided in the concrete layer.

[0125] Example 6 Prefabricated building interior partition board

[0126] like Figure 21-25 As shown, it includes the filling wallboard of embodiment 5, which includes an inner partition board 4, and the inner partition board 4 is made of a concrete layer. The inner partition board 4 includes a front and rear plane 41, an upper and lower end surface and a left and right facade. The upper and lower end surfaces are both provided with an end surface groove 42, and the left and right facades are both provided with a facade groove 43. The end surface groove 42 and the facade groove 43 are mutually interpenetrating, so that when pouring the board seam 45 of the inner partition board 4, the mortar penetrates the end surface groove 42 and the facade groove 43.

[0127] The edges of the front and rear planes 41 of the inner partition wall panels 4 are both provided with notches 44, and the notches 44 of two adjacent inner partition wall panels 4 surround to form an expanded cavity. The expanded cavity plays a role in reinforcement and positioning after pouring mortar, and it can also reserve a connection space for the sleeve of the template 6. Advantageously, the notches 44 are semicircular, and the notches 44 of two adjacent inner partition wall panels 4 surround to form a circular expanded cavity.

[0128] Example 7: Internal partition board seam limiter for wire rod positioning member (facade positioning member 5)

[0129] like Figure 26-28As shown, the facade positioning member 5 is used to be installed between the inner partition wall board 4 and the adjacent vertical wall 71 and to be installed between adjacent inner partition wall boards 4 .

[0130] The vertical positioning member 5 includes a positioning member body 51 , two positioning rods 52 and a drawing rod 53 .

[0131] The positioning member body 51 includes left and right ends, front and rear ends, and upper and lower ends. Both left and right sides of the positioning member body 51 are provided with protrusions 512 that match the left and right facades of the inner partition board 4. Two positioning rods 52 are respectively arranged on the left and right protrusions 512 and extend outward. The drawing rod 53 passes through the positioning member body 51, and both ends of the drawing rod 53 extend toward the front and rear ends. Both ends of the drawing rod 53 are provided with screw thread ends 54. The upper and lower ends of the positioning member body 51 are also provided with through holes 511 for the circulation of mortar during pouring, and when the pouring is completed, an integrated and firm mortar structure is formed.

[0132] Specifically, the positioning member body 51 is formed by connecting the left end plate, the right end plate, the front end plate and the rear end plate, which is beneficial to increase the size of the through hole 511. The left end plate, the right end plate, the front end plate and the rear end plate are all made of metal materials and can be made by conventional means.

[0133] Advantageously, the positioning rod 52 has a pointed end 521 to facilitate insertion into the inner partition board 4 or penetration into the drill hole 112 .

[0137] As an example, the inner partition board 4 has a through hole 46 for inserting a drill, and the positioning rod 52 penetrates the through hole 46 for inserting a drill. The through hole 46 for inserting a drill is formed when the inner partition board 4 is manufactured. Usually, the built-in tension screw steel mesh frame includes an insert connector, and the insert hole 112 of the insert connector is used for inserting a drill for positioning, and the inserting drill is pulled out to form the insert hole 46.

[0138] Specifically, vertically extending vertical grooves 43 are provided on the left and right vertical surfaces of the inner partition wall board 4, and the protrusions 512 are accommodated in the vertical grooves 43 and abut against the bottom surface of the vertical grooves 43. The vertical grooves 43 increase the space of the board seams 45 of the inner partition wall board 4, making it easier to pour mortar, and the mortar can fix the inner partition wall board 4 after solidification.

[0139] Advantageously, the edges of the front and rear planes 41 of the inner partition wall panels 4 are both provided with notches 44, the notches 44 corresponding to the wire drawing rods 53, the notches 44 of two adjacent inner partition wall panels 4 surround to form an enlarged cavity, and the ends of the wire drawing rods 53 are accommodated in the enlarged cavity.

[0144] From the perspective of function, the inner wall 7 can be divided into a load-bearing wall or a non-load-bearing wall, and can also be divided into a shear wall and a non-shear wall. From the perspective of structure, the inner wall 7 is divided into a horizontal beam 72 and a vertical wall 71.

[0145] The floor is the bottom structure such as the ground or floor slab used to enclose the building space.

[0146] There is a board gap 45 between the left and right facades of the inner partition boards 4 of the plurality of assembled building inner partition boards.

[0147] The upper positioning member 8 is installed between the cross beam 72 and the upper end surface of the inner partition wall board 4, and the upper positioning member 8 is fixed to the cross beam 72.
