Description

Technical Field

[0001] The present invention relates to the technical field of building auxiliary equipment, and in particular to a steel bar node connection device, a steel bar mesh and a steel bar mesh connection system. Background Art

[0002] Steel mesh is a commonly used component in the current construction field. It is formed by staggered arrangement of multiple steel bars and fixing the node positions. In actual application, steel mesh is generally divided into hoisting type and on-site laying type. The hoisting type is generally prefabricated off-site and hoisted to the designated location by hoisting. The on-site laying type is to directly build steel bars on-site at the construction site and fix the steel nodes on-site to form the final steel mesh.

[0003] Because the hoisted steel mesh is prefabricated off-site, its construction flexibility is relatively high, and the order of arranging the steel bars and connecting the nodes is generally not restricted. For example, the steel bars can be arranged first and then the steel bar nodes can be connected; or the steel bars can be directly clamped on the existing node connectors to form a steel mesh, etc. The steel mesh formed by the on-site paving method needs to arrange the steel bars first and then connect the steel bar nodes because it is operated at the construction site, that is, it can only be constructed by connecting the steel bar nodes later. Whether it is a hoisted steel mesh or a on-site laid steel mesh, when the steel bars are arranged and then the steel bar nodes are connected, it is limited by the working scene. When connecting the steel bar nodes, it is generally only possible to weld or tie them. When welding is used, the welds at the nodes will damage the surface of the steel bars, reduce the cross-sectional area of ​​the steel bars and cause stress concentration, thus affecting the stability of the overall steel mesh. The binding method mostly uses metal binding wires, and sometimes the remaining part of the binding wires will be higher than the height of the reserved protective layer. After pouring, the remaining part will extend out of the concrete surface, which will not only affect the appearance of the concrete after pouring, but also affect the service life of the concrete structure under rain corrosion, and the labor intensity of the binding operation is also relatively high.

[0004] Based on this, for the steel mesh that arranges the steel bars first and then connects the steel bar nodes, some places will use some connectors to fix the steel bar nodes. However, due to the limitation that the arrangement of the steel bars has been completed when the steel bar nodes are connected, the clips for this method can only use semi-closed connectors, that is, there is an open gap at the bottom of the buckle, and the installation is achieved during construction by relying on the vertical downward gravity, pressure and the elasticity of the buckle itself. However, the semi-open structure cannot achieve all-round fixation and closed fastening of the cross-intersection nodes of the steel bars, which greatly affects its firmness in connecting the steel bar nodes. Especially before the concrete is poured, when the steel mesh is subjected to greater pressure, the steel bars at the corresponding position are very likely to fall off from the open gap of the buckle, which will cause the steel bar node connection at the corresponding position to fail.

[0005] Therefore, with regard to the method of pre-arranging steel bars and then connecting the steel bar nodes, how to improve the stability of the steel bar node connections in a convenient way without affecting the appearance and service life of the concrete has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] A technical problem to be solved by the present invention is: how to improve the stability of steel bar node connection in a convenient way without affecting the appearance and service life of concrete.

[0007] In order to solve the above technical problems, the present disclosure provides a steel bar node connection device, which includes:

[0008] A first buckle and a second buckle; the first buckle and the second buckle are structures that can be connected together by buckling and fixedly connect the steel bar node in a closed manner;

[0009] The first buckle comprises a first arc-shaped structure and a second arc-shaped structure; the first arc-shaped structure and the second arc-shaped structure are stacked up and down and staggered with each other in the axial direction; a clamping member is arranged on the first arc-shaped structure and / or the second arc-shaped structure;

[0010] The second buckle includes a third arc-shaped structure corresponding to the first arc-shaped structure, and a fourth arc-shaped structure corresponding to the second arc-shaped structure; a snap-fitting structure cooperating with the snap-fitting member is provided on the third arc-shaped structure and / or the fourth arc-shaped structure.

[0011] In some embodiments, in the aforementioned steel bar node connection device, the clamping member is a clamping head; and the clamping structure is a clamping slot for the clamping head to be inserted into.

[0012] In some embodiments, in the aforementioned steel bar node connection device, the positions on the first buckle and the second buckle corresponding to the steel bar node connection are provided with hollowing out to avoid the steel bar node connection.

[0013] A second aspect of the present application provides a steel mesh, which includes the aforementioned steel bar node connection device.

[0014] A third aspect of the present application provides a steel mesh connection system, which includes the aforementioned steel mesh.

[0015] Beneficial Effects

[0016] On the one hand, the present invention provides a steel bar node connection device, which mainly includes a first buckle and a second buckle. When used, the steel bar node can be connected by matching the first buckle and the second buckle to each other and fastening them, that is, the entire method of connecting the steel bar node only needs "one-to-one buckle", and the connection method is convenient and fast. At the same time, since the first buckle includes a first arc structure and a second arc structure, and the second buckle corresponds to the structure of the first buckle, that is, the second buckle includes a third arc structure corresponding to the first arc structure and a fourth arc structure corresponding to the second arc structure. When the first buckle and the second buckle are buckled, the first arc structure cooperates with the third arc structure to enclose the transverse steel bar at the steel bar node, and the second arc structure cooperates with the fourth arc structure to enclose the longitudinal steel bar at the steel bar node. In this way, when connecting the steel bar node, the two horizontal and vertical steel bars at the steel bar node can be enclosed and connected at the same time. Compared with the traditional semi-open or semi-closed connector, this form can avoid the problem of steel bars falling off from the connector, and greatly improves the stability of the steel bar node connection.

[0017] In addition, compared with the traditional closed steel bar node connector that is fixed with bolts, the structure of the present invention is simpler and easier to operate. The steel bar node connection device of the present invention is more conducive to mechanized construction operations due to its simple structure and more convenient operation method.

[0018] Furthermore, because the steel bar node connection device of the present invention can be constructed directly on the laid steel bar mesh, it can be constructed without changing the gap between the two horizontal and vertical steel bars at the existing steel bar node, so that it can greatly reduce construction errors and the impact on the laid steel bar mesh.

[0019] In summary, compared with binding or welding, the steel bar node connection device of the present invention not only does not damage the steel bars, but also because the first buckle, the second buckle and other components are more adaptable to the shape of the steel bars, and they are all prefabricated standard components, there will be no situation where the components extend out of the concrete surface after pouring, which will not affect the appearance of the concrete after pouring, and greatly extend the service life of the concrete structure. Compared with the existing semi-closed connectors, the closed wrapping of the arc structure of the first buckle and the second buckle of the present invention fits the surface of the steel bar more closely, and is easy to install. While improving the construction efficiency, it also well guarantees the stability of the steel bar node connection, thereby improving the overall stability of the steel mesh. Compared with the traditional closed steel bar node connector, the present invention not only does not affect the gap between the two horizontal and vertical steel bars at the steel bar node, but also has a simpler structure, and only needs "one-to-one buckle" during construction, and its construction is more convenient and quick. The present invention solves the technical problems existing in the prior art well, which is conducive to popularization and application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Figure 4 The orientation is used as a reference.

[0038] A steel bar node connection device proposed in an embodiment of the present invention mainly includes a first buckle 1 and a second buckle 2. The first buckle 1 and the second buckle 2 are structures that can be connected together by buckling and close-type fixed connection of the steel bar node. The first buckle 1 includes a first arc structure 101 and a second arc structure 102, and the first arc structure 101 and the second arc structure 102 are stacked up and down and staggered with each other in the axial direction. A snap-fitting piece is provided on the first arc structure 101 and / or the second arc structure 102. The structure of the second buckle 2 corresponds to the structure of the first buckle 1, that is, the second buckle 2 includes a third arc structure 201 corresponding to the first arc structure 101, and a fourth arc structure 202 corresponding to the second arc structure 102. A snap-fitting structure that cooperates with the snap-fitting piece is provided on the third arc structure 201 and / or the fourth arc structure 202.

[0039] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0040] Example 1

[0041] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 This embodiment provides a steel bar node connection device, which includes a first buckle 1 and a second buckle 2. The first buckle 1 and the second buckle 2 can be made of metal parts. The structures of the first buckle 1 and the second buckle 2 correspond to each other. For details, refer to Figure 4 The first buckle 1 includes a first arc structure 101 and a second arc structure 102, the first arc structure 101 and the second arc structure 102 are stacked up and down, that is, the first arc structure 101 is located above the second arc structure 102, and the first arc structure 101 and the second arc structure 102 are staggered in the axial direction, or cross-set. This setting is mainly to adapt to the horizontal and vertical steel bars at the steel bar node, because the horizontal and vertical steel bars at the steel bar node are also stacked up and down and staggered in the axial direction. Figure 6 As shown, the transverse steel bars, i.e., the X-direction steel bars, are stacked above the longitudinal steel bars, i.e., the Y-direction steel bars. Figure 6, the first arc structure 101 is used to adapt to the transverse steel bars at the steel bar nodes, and the second arc structure 102 is used to adapt to the longitudinal steel bars at the steel bar nodes. The second buckle 2 includes a third arc structure 201 and a fourth arc structure 202, and the third arc structure 201 and the fourth arc structure 202 are stacked up and down, that is, the third arc structure 201 is located above the fourth arc structure 202, and the third arc structure 201 and the fourth arc structure 202 are staggered in the axial direction, or cross-set. On the one hand, this setting is to adapt to the two horizontal and vertical steel bars at the steel bar nodes, that is, the third arc structure 201 is used to adapt to the transverse steel bars at the steel bar nodes, and the fourth arc structure 202 is used to adapt to the longitudinal steel bars at the steel bar nodes; on the other hand, the third arc structure 201 is used to correspond to the first arc structure 101 and can be closed after the cross-locking, and similarly, the fourth arc structure 202 is used to correspond to the second arc structure 102 and can be closed after the cross-locking. Wrap the longitudinal steel bar. The closed wrapping mentioned here is relative to the semi-open connector structure in the prior art, that is, when the first buckle 1 and the second buckle 2 are buckled, the third arc structure 201 and the first arc structure 101 form a first cylinder structure that covers the transverse steel bars, and the fourth arc structure 202 and the second arc structure 102 form a second cylinder structure that covers the longitudinal steel bars, and the first cylinder structure and the second cylinder structure are connected and fixed to each other, and there will be no openings on the first cylinder structure and the second cylinder structure that will cause the steel bars to slip out. When in use, refer to Figure 6 The first buckle 1 and the second buckle 2 can be along Figure 6 The directions of arrows B1 and B2 are connected together by buckling. The state after buckling is shown in Figure 7 shown.

[0042] The first buckle 1 is provided with a clamping piece, and the second buckle 2 is provided with a clamping structure that can cooperate with the clamping piece on the first buckle 1. When the first buckle 1 and the second buckle 2 are buckled together, the clamping piece and the clamping structure cooperate to achieve a stable connection between the first buckle 1 and the second buckle 2.

[0043] Further, see Figure 4 , Figure 5 , Fig.11 The clamping member can be selected as a clamp head 3, and the clamping structure can be selected as a clamping slot 4 for inserting the clamp head 3. Figure 4 and Fig.11 As shown, it includes a clamp handle 301 and a ramp head 302 .

[0044] For the first buckle 1, a snap-fitting piece can be provided on the first arc structure 101 and / or the second arc structure 102. Here, "and / or" means: 1. The same snap-fitting piece can be provided on both the first arc structure 101 and the second arc structure 102; 2. The snap-fitting piece can also be provided only on the first arc structure 101 or the second arc structure 102. In this case, if a snap-fitting piece is provided on the first arc structure 101, other forms of snap-fitting mechanisms or no snap-fitting mechanisms can be provided on the second arc structure 102. Of course, in this form, from the effect point of view, the connection effect is better when a snap-fitting piece is provided on the first arc structure 101 and other forms of snap-fitting mechanisms are provided on the second arc structure 102. Similarly, if a clamping piece is provided on the second arc-shaped structure 102, other forms of clamping mechanisms may be provided on the first arc-shaped structure 101, or no clamping mechanism may be provided. Similarly, from the effect point of view, the connection effect is better when a clamping piece is provided on the second arc-shaped structure 102 and other forms of clamping mechanisms are provided on the first arc-shaped structure 101.

[0045] Taking the case where the same clamping member is provided on the first arc structure 101 and the second arc structure 102 as an example, Figure 4 As shown, the handle 301 is connected to the first arc structure 101 and the second arc structure 102, and the slope head 302 is connected to the front end of the handle 301. The front end here refers to the end that can be inserted into the slot 4 when in use. Fig.11 The slope head 302 can be in the following form: the slope head 302 gradually tilts upward or downward from the front end to the rear to form a slope surface 3021. Fig.11 Taking the upward tilting method as an example, the rear end of the slope surface 3021 forms a locking position 3022 for locking in the card slot 4. When in use, the slope head 302 moves toward the card slot 4. As the front end of the slope head 302 gradually extends into the card slot 4, the slope head 302 undergoes elastic deformation. Due to the effect of the slope surface 3021 on the slope head 302, the slope head 302 smoothly slides into the card slot 4. After the slope head 302 completely passes through the card slot 4, the slope head 302 that has undergone elastic deformation before quickly resets, and the locking position 3022 of the slope head 302 is locked on the top of the card slot 4, thereby completing the matching of the card head 3 and the card slot 4. The matching state can be referred to Fig.11 As shown in the figure on the right side of the middle arrow. Of course, the clamp head 3 can also be in other forms, as long as it can be matched with the clamping slot.

[0046] In addition, the connection between the first arc structure 101 and the second arc structure 102 can be achieved by, but not limited to, welding, and the welding point can be located in the middle of the first arc structure 101 and the second arc structure 102, so that the first buckle 1 as a whole is more balanced and stable. In addition, the first arc structure 101 and the second arc structure 102 can be connected by setting a metal connecting frame 20, and welding and other connection methods can be used between the first arc structure 101 and the metal connecting frame 20, and between the second arc structure 102 and the metal connecting frame 20. The metal connecting frame 20 can increase the connection area between the first arc structure 101 and the second arc structure 102, so that the first buckle 1 as a whole is more balanced and stable. In addition, the connection method of the third arc structure 201 and the fourth arc structure 202 in the second buckle 2 can refer to the first buckle 1, which will not be repeated here. In addition, refer to Fig. 9 and Fig.10 In order to ensure that the gap between the two horizontal and vertical steel bars at the steel bar node remains unchanged as much as possible, hollowing can be set at the position corresponding to the connection of the steel bar node on the first buckle 1 and the second buckle 2 to avoid the connection of the steel bar node, that is, hollowing can be set on the first arc structure 101 and the second arc structure 102, respectively recorded as hollowing out 1011 and hollowing out 1021, hollowing out 1011 is located at the position where the first arc structure 101 is connected to the second arc structure 102, and hollowing out 1021 is located at the position where the second arc structure 102 is connected to the first arc structure 101, that is, hollowing out 1011 and hollowing out 1021 are connected and communicated. Similarly, the third arc structure 201 and the fourth arc structure 202 are also provided with hollows, which are respectively recorded as hollow three 2011 and hollow four 2021. Hollow three 2011 is located at the position where the third arc structure 201 is connected with the fourth arc structure 202, and hollow four 2021 is located at the position where the fourth arc structure 202 is connected with the third arc structure 201, that is, hollow three 2011 and hollow four 2021 are connected and connected. The purpose of providing hollows on the first buckle 1 and the second buckle 2 is mainly to make the position where the transverse steel bars and the longitudinal steel bars cross contact, that is, the position where the steel bar nodes are connected, so as not to affect the contact between the transverse steel bars and the longitudinal steel bars as much as possible, and thus not to affect the gap between the transverse steel bars and the longitudinal steel bars.

[0047] The buckling mode of the first buckle 1 and the second buckle 2 realizes a closed fixed structure when fixing the steel bar node, so that the effect of fixing the steel bar node is more stable, and the specific curvature of the arc structure can be selected according to the diameter of the steel bar, that is, it is only necessary to make the curvature of the arc structure compatible with the corresponding steel bar. At the same time, the axial staggered angle of the first arc structure 101 and the second arc structure 102 and the axial staggered angle of the third arc structure 201 and the fourth arc structure 202 can be selected according to the angle between the two horizontal and vertical steel bars at the steel bar node, that is, if the angle between the two horizontal and vertical steel bars at the steel bar node is set to 90°, the corresponding axial staggered angle of the first arc structure 101 and the second arc structure 102, that is, the angle between the axial directions is also 90°. Similarly, the axial staggered angle of the third arc structure 201 and the fourth arc structure 202, that is, the angle between the axial directions is also 90°. Therefore, when the first buckle 1 and the second buckle 2 are produced, production adjustments can be made for the steel bar angles of different angles in the steel mesh. In order to stably fix the steel bar and reduce the shaking of the steel bar in the fixing area after fixation, the diameter of the first buckle 1 and the second buckle 2 is matched with the diameter of the fixed steel bar.

[0048] In addition, the arrangement of the clamping member and the clamping structure is further described by taking examples. The arrangement of the clamping member and the clamping structure in this embodiment may include the following:

[0049] Card connection form 1: reference Fig. 9 , the first arc structure 101 and the second arc structure 102 are both provided with a clamp 3, and multiple clamps 3 can be provided on the first arc structure 101 and the second arc structure 102, for example, three clamps 3 can be provided on the first arc structure 101, and three clamps 3 can also be provided on the second arc structure 102. Of course, the number of clamps 3 can be selected according to needs. On the first arc structure 101, the three clamps 3 are arranged at intervals along the extension direction of the first arc structure 101, that is, the X direction, and in order to ensure the stability of the connection, one of the three clamps 3 is arranged as much as possible in the middle of the extension direction of the first arc structure 101, and the other two clamps 3 are arranged as much as possible near the two ends of the first arc structure 101. On the second arc structure 102, three clamps 3 are arranged at intervals along the extension direction of the second arc structure 102, that is, the Y direction, and in order to ensure the stability of the connection, one of the three clamps 3 is arranged as much as possible in the middle part of the extension direction of the second arc structure 102, and the other two clamps 3 are arranged as much as possible close to the two ends of the second arc structure 102.

[0050] refer to Fig.10Corresponding to the first buckle 1, the third arc structure 201 and the fourth arc structure 202 of the second buckle 2 are correspondingly provided with card slots 4, and the positions and number of the card slots 4 correspond to the positions and number of the clamping heads 3 on the first buckle 1, that is, three card slots 4 are provided on the third arc structure 201, and the positions of the three card slots 4 correspond to the positions of the three clamping heads 3 on the first arc structure 101, and three card slots 4 are also provided on the fourth arc structure 202, and the positions of the three card slots 4 correspond to the positions of the three clamping heads 3 on the second arc structure 102.

[0051] When in use, the first buckle 1 and the second buckle 2 are respectively moved in the diagonal direction of the steel bar node. Figure 6 As shown by arrows B1 and B2, after the first buckle 1 and the second buckle 2 are close to each other, the clamp head 3 is gradually inserted into the clamping slot 4 to achieve a quick connection between the clamp head 3 and the clamping slot 4, thereby achieving Figure 7 The buckling results in .

[0052] Snap-on form 2: The difference from "Snap-on form 1" is that the first arc structure 101 is provided with a clamping head 3, the second arc structure 102 is provided with a clamping slot 4, and correspondingly, the third arc structure 201 is provided with a clamping slot 4, and the fourth arc structure 202 is provided with a clamping head 3. When in use, the clamping head 3 on the first arc structure 101 is clamped into the clamping slot 4 on the third arc structure 201, and the clamping head 3 on the fourth arc structure 202 is inserted into the clamping slot 4 of the second arc structure 102, thereby completing the buckling of the first buckle 1 and the second buckle 2. For other structures and use processes in this form, please refer to "Snap-on form 1", which will not be repeated here.

[0053] Example 2

[0054] Reference Figure 1 , Figure 2 , Figure 3 , Figure 8 , this embodiment also provides a steel bar node connection construction device, which is used to install the steel bar node connection device in Example 1 on the steel bar mesh. The steel bar node connection construction device includes a grabbing portion 5 and a fixed frame 7 equipped with a moving portion 6. A placement frame 8 is provided on the fixed frame 7, and the first clip 1 and the second clip 2 are placed in the placement frame 8. Two placement frames 8 can be provided to respectively contain the first clip 1 and the second clip 2. The grabbing portion 5 is provided on the fixed frame 7, and is used to grab the first clip 1 and the second clip 2 from the placement frame 8 and buckle the first clip 1 and the second clip 2 at the steel bar node to close and fix the steel bar node. Refer to Figure 1The gripping part 5 can adopt the existing multi-axis mechanical arm (or multi-axis robot). Since the first buckle 1 and the second buckle 2 need to be clamped and fastened in the present invention, there are two multi-axis mechanical arms, and the front end of each multi-axis mechanical arm is provided with an existing electric claw (or electric clamp, mechanical claw) structure (because it is an existing structure, it is not shown in the figure). When in use, the electric claws are extended into the placement frame 8 through the two multi-axis mechanical arms, and the electric claws on the two multi-axis mechanical arms are used to clamp the first buckle 1 and the second buckle 2 respectively, and the electric claws that clamp the first buckle 1 and the second buckle 2 are sent to the steel bar node position by the two multi-axis mechanical arms, so that the first buckle 1 and the second buckle 2 are in Figure 6 Then, by using the actions of the two multi-axis robotic arms, the first buckle 1 and the second buckle 2 are buckled together in the directions indicated by the arrows B1 and B2 in the figure to form Figure 7 The structure shown in , completes a steel bar node fixing cycle.

[0055] Furthermore, in order to ensure the stability of the placement of the first buckle 1 and the second buckle 2 and to ensure the position of the electric claw clamping, a stacking rack 9 can be set in the placement frame 8. Figure 8 The stacking rack 9 includes a rack plate 901 and a rack head 902. The rack head 902 is arranged at the top of the rack plate 901, and the rack head 902 is a "human" shaped structure. The rack head 902 is mainly used to support the first buckle 1 and the second buckle 2. The reason why the rack head 902 is set to a "human" shaped structure is mainly to adapt to the angle between the first buckle 1 and the second buckle 2. The so-called angle between the first buckle 1 and the second buckle 2, taking the first buckle 1 as an example, because the axial directions of the first arc structure 101 and the second arc structure 102 are staggered with each other, that is, the axial directions of the first arc structure 101 and the second arc structure 102 will form an angle α1. At this time, the angle of the first buckle 1 is the axial angle α1 between the first arc structure 101 and the second arc structure 102. Similarly, the angle of the second buckle 2 refers to the angle α2 between the axial directions of the third arc structure 201 and the fourth arc structure 202, such as Fig.14 As shown. The top angle α2 of the "human" shaped structure of the frame head 902 is the same as the angle α1, so that the direction of the angle α1 of the first buckle 1 can be directed toward the top angle direction of the "human" shaped structure, and then the first buckle 1 can be buckled on the top angle of the "human" shaped structure, which can not only ensure the stability of the placement of the first buckle 1, but also make the first buckle 1 more neatly and uniformly placed, which is also more conducive to mechanized construction. The angle and position of the electric claw are more fixed, thereby ensuring that the first buckle 1 and the second buckle 2 can be accurately buckled at the steel bar node during construction.

[0056] The shelf plate 901 can be a hard metal plate, and the shelf plate 901 is arranged in the placement frame 8 and can be fixed in the placement frame 8, that is, the shelf plate 901 can be directly fixedly connected to the bottom plate of the placement frame 8, or can be fixedly connected to the side plate of the placement frame 8, or can be fixedly connected to both the bottom plate and the side plate of the placement frame 8. In addition, in order to facilitate the flexible arrangement or replacement of the stacking rack 9, the fixing method of the shelf plate 901 can also be selected in a plug-in manner, that is, a slot 10 for inserting the shelf plate 901 is provided in the placement frame 8. When the stacking rack 9 is set, the selected shelf plate 901 is inserted into the corresponding slot 10. When the stacking rack 9 needs to be replaced, that is, for example: in order to adapt to the different angles α1 between the first buckle 1 and the second buckle 2, when the stacking rack 9 with a different top angle α2 of the rack head 902 needs to be replaced, the original stacking rack 9 is taken out from the slot 10, and the newly selected stacking rack 9 is placed in the slot 10.

[0057] Furthermore, in order to facilitate the grasping of the electric claw of the grasping part, a grasping part can be provided on the outside of the first buckle 1 and the second buckle 2. The grasping part can also be directly used as a connecting frame connecting the arc structure. For example, taking the first buckle 1 as an example, the grasping part can be directly used as a metal connecting frame 20 connecting the first arc structure 101 and the second arc structure 102. As for the "outside of the first buckle 1 and the second buckle 2" mentioned here, it is relative to the "inside" of the first buckle 1 and the second buckle 2. The "inside" of the first buckle 1 and the second buckle 2 is the side facing the steel bar. After the first buckle 1 and the second buckle 2 are buckled, the "inside" can fix the steel bar in a closed manner. That is to say, the grasping part is set on the side that does not affect the closed fixation of the steel bar. Generally speaking, still taking the first buckle 1 as an example, the grasping part can be set at the position where the first arc structure 101 and the second arc structure 102 are connected. In order to facilitate the grasping of the electric claw, two front and rear grasping surfaces, namely the first grasping surface 1101 and the second grasping surface 1102, can be reserved on the grasping part along the horizontal direction; when grasping, the electric claw can directly pinch the first grasping surface 1101 and the second grasping surface 1102 to grasp the first buckle 1 and the second buckle 2. When the first buckle 1 and the second buckle 2 are placed on the stacking rack 9, the grasping parts are also uniformly facing upward, which is also more convenient for grasping the grasping part 5. In addition, in order to increase the grasping stability of the grasping part 5, some structures that increase the friction force can be set on the first grasping surface 1101 and the second grasping surface 1102, such as particles that increase the friction force, etc., or some limit grooves 1103 that can limit the grasping position of the electric claw can be set. When grasping, the electric claw only needs to pinch the position of the limit groove 1103 to ensure the stability of grasping, that is, Figure 4 and Figure 5 shown.

[0058] In addition, the stacking rack 9 can be arranged in two rows, i.e. Figure 8As shown, the stacking racks 9 in the upper row and the stacking racks 9 in the lower row should be staggered in the vertical direction so as not to affect the grasping of the grasping part 5. When two rows of stacking racks 9 are provided and the stacking racks 9 are in a plug-in form, the slots 10 for inserting the stacking racks 9 in the upper row are provided on the side wall of the placement frame 8, and the slots 10 for inserting the stacking racks 9 in the lower row can be provided on the side wall or the bottom of the placement frame 8, which can be provided as required.

[0059] In addition, the moving part 6 includes a support frame 601 and a walking arm, wherein the support frame 601 can be a hard metal frame. The support frame 601 is connected to the bottom of the fixed frame 7, that is, the bottom of the fixed frame 7 is provided with a connecting shaft 13 extending to the bottom of the fixed frame 7, and the top of the connecting shaft 13 can be connected to the fixed frame 7 through bearings and other components, so that the connecting shaft 13 can rotate relative to the fixed frame 7. A driven gear 12 is sleeved on the connecting shaft 13, and the driven gear 12 is fixed to the connecting shaft 13. The driven gear 12 is also located below the fixed frame 7, and the driven gear 12 can be set above the connecting shaft 13 and close to the fixed frame 7. The bottom end of the connecting shaft 13 is fixedly connected to the support frame 601, and a second motor 14 is also provided on the fixed frame 7, and the second motor 14 can also be connected to the bottom of the fixed frame 7 and fixedly connected to the fixed frame 7. The driving gear 15 at the output end of the second motor 14 meshes with the driven gear 12 to drive the driven gear 12 to rotate, and the rotation of the driven gear 12 will inevitably drive the connecting shaft 13 to rotate, and then the support frame 601 will also rotate. The function of the support frame 601 is mainly to facilitate the fixing frame 7 to adjust the direction by rotating.

[0060] The shape of the support frame 601 can be the same as that of the fixing frame 7 , but the area of ​​the support frame 601 is preferably smaller than that of the fixing frame 7 to avoid the situation where the support frame 601 hinders the movement of the fixing frame 7 .

[0061] In addition, refer to Figure 1 and 2 There are two groups of walking arms, and the two groups of walking arms are respectively located on the left and right sides of the moving direction of the fixed frame 7. Figure 1 and 2 The direction of the middle arrow C is the moving direction of the fixed frame 7. The traveling arm is a connecting rod mechanism, and specifically, the traveling arm includes two connecting rod pairs 602 and an auxiliary rod 603. The auxiliary rod 603 is connected to the bottom ends of the two connecting rod pairs 602 located on the same side of the fixed frame 7. On the one hand, the movement synchronization of the two connecting rod pairs 602 on one side can be strengthened. On the other hand, the auxiliary rod 603 is used to support on the steel mesh, thereby providing a stable support effect on the fixed frame 7.

[0062] The fixed frame 7 is provided with a transmission shaft 16, which is two front and rear transmission shafts 16 along the moving direction of the fixed frame 7, or in other words, the two transmission shafts 16 are arranged at the front and rear ends of the fixed frame 7 based on the moving direction of the fixed frame 7. Each of the two ends of each transmission shaft 16 is connected to a connecting rod pair 602. A driven bevel gear 17 is fixedly sleeved on the transmission shaft 16. In order to simplify the structure, the driven bevel gear 17 can be arranged on only one of the transmission shafts 16. The fixed frame 7 is also provided with a first motor 18. The driving bevel gear 19 at the output end of the first motor 18 meshes with the driven bevel gear 17 to drive the transmission shaft 16 connected to the driven bevel gear 17 to rotate, and the position of the first motor 18 only needs to meet the requirement that the driving bevel gear 19 can mesh with the driven bevel gear 17 to rotate.

[0063] Furthermore, the connecting rod pair 602 includes an upper connecting rod 6024 and a lower connecting rod 6023, and the upper connecting rod 6024 and the lower connecting rod 6023 are movably connected through the connecting rod shaft 21, so that the lower connecting rod 6023 can rotate around the connecting rod shaft 21. The auxiliary rod 603 is connected to the bottom of the lower connecting rod 6023.

[0064] Further, such as Figure 1 , Figure 2 and Fig.12 As shown, a through slot 6021 may be provided on the upper connecting rod 6024, and the connecting rod shaft 21 is located at one side of the through slot 6021, and an internal threaded hole is provided at one end of the connecting rod shaft 21. A screw 6025 with a clamping cap 6022 is provided on the other side of the through slot 6021, and the screw 6025 passes through the through slot 6021 and extends into the internal threaded hole of the connecting rod shaft 21 and is threadedly engaged therewith. The lower connecting rod 6023 is connected to the connecting rod shaft 21 through a bearing 211, so that the lower connecting rod 6023 can rotate around the connecting rod shaft 21.

[0065] When in use, the screw 6025 is screwed to move the clamping cap 6022 toward the upper connecting rod 6024 until it clamps one side of the upper connecting rod 6024, and the connecting rod shaft 21 clamps the other side of the upper connecting rod 6024, and the upper connecting rod 6024 is clamped by the clamping cap 6022 and the connecting rod shaft 21 to complete the positioning between the connecting rod shaft 21 and the upper connecting rod 6024. When adjustment is required, the clamping cap 6022 is screwed to move away from the upper connecting rod 6024, but the screw 6025 can be kept from being separated from the internal threaded hole of the connecting rod shaft 21. At this time, the connecting rod shaft 21 can be moved to a specified position along the through groove 6021, and the screw 6025 is screwed again to make the clamping cap 6022 and the connecting rod shaft 21 clamp the upper connecting rod 6024 again to complete the adjusted positioning. At this time, the connecting rod shaft 21 does not need to rotate. The rotation of the lower connecting rod 6023 around the connecting rod shaft 21 is achieved by the bearing 211. Furthermore, in order to ensure the clamping stability of the clamping cap 6022 and the connecting rod shaft 21 on both sides of the upper connecting rod 6024, structures for increasing the friction may be provided on the surface of the clamping cap 6022 facing the upper connecting rod 6024, on the surface of the connecting rod shaft 21 facing the upper connecting rod 6024, and on both sides of the upper connecting rod 6024. For example, some materials that can increase the friction may be provided, some particles or protrusions that increase the friction may be provided, or both materials that increase the friction and particles or protrusions that increase the friction may be provided on the material.

[0066] It is understandable that when the distance that the fixing frame 7 needs to move each time is short, the length of the connecting rod pair 602 needs to be reduced, and the connecting rod shaft 21 needs to be adjusted to move along the through slot 6021 toward the fixing frame 7 and fixed at the specified position. At this time, the rotation radius formed between the connecting rod shaft 21 and the rotating shaft 16 is reduced, thereby reducing the distance of the fixing frame 7 moving in a single time; and when the distance that needs to be moved each time is large, the connecting rod shaft 21 can be adjusted in the opposite direction. Through this structure, adaptive adjustments can be made according to the needs of each walking distance, thereby improving the flexibility for different construction scenes and ensuring the fixation of each steel bar node.

[0067] The working process of the steel bar node connection construction device of the present invention is described as follows:

[0068] by Figure 1 and Fig.13 For reference, Figure 1 Take the right movement in the example of moving forward:

[0069] The first stage: the auxiliary rod 603 is pressed on the steel mesh, and the first motor 18 is started to make the active bevel gear 19 mesh with the driven bevel gear 17 to rotate, thereby driving the transmission shaft 16 connected to the driven bevel gear 17 to rotate. At the same time, because the lower connecting rod 6023 and the auxiliary rod 603 are fixed, the upper connecting rod 6024 will rotate clockwise around the transmission shaft 16, thereby driving the fixing frame 7 to move forward until the support frame 601 at the bottom of the fixing frame 7 is pressed on the steel mesh;

[0070] The second stage: the upper connecting rod 6024 continues to rotate clockwise, so that the lower connecting rod 6023 and the auxiliary rod 603 are lifted. At this time, the walking arm does not support the fixed frame 7, and the bottom of the fixed frame 7 is supported only by the support frame 601. When the upper connecting rod 6024 continues to rotate clockwise so that the connecting rod shaft 21 reaches the highest point, the lower connecting rod 6023 and the auxiliary rod 603 move forward and fall at the same time, so that the auxiliary rod 603 moves forward a distance until the auxiliary rod 603 is pressed on the steel mesh again;

[0071] The third stage: the upper connecting rod 6024 continues to rotate clockwise, so that the fixing frame 7 is lifted, and the moving process of the fixing frame 7 is completed. The two electric claws can grab the first buckle 1 and the second buckle 2 from the placement frame 8 respectively, and send the first buckle 1 and the second buckle 2 to the designated steel bar node, that is, Figure 6 Position as shown and snap on.

[0072] For the specific principle process, please refer to Fig.13 .

[0073] Rotation process of the fixed frame 7: first implement the above-mentioned "first stage" process, then the upper connecting rod 6024 continues to rotate clockwise, so that the lower connecting rod 6023 and the auxiliary rod 603 are lifted and leave the steel mesh, so that the upper connecting rod 6024 stops transmission. The timing of stopping transmission of the upper connecting rod 6024 can be selected according to needs, as long as the auxiliary rod leaves the steel mesh and does not affect the rotation of the fixed frame 7. Then start the second motor 14. At this time, because the support frame 601 is pressed against the steel mesh, the support frame 601 and the connecting shaft 13 will not rotate, and because the second motor 14 is fixedly connected to the fixed frame 7, and the top of the connecting shaft 13 is movably connected to the fixed frame 7 through the bearing 211, at this time, the fixed frame 7 will rotate with the connecting shaft 13 as the axis until it rotates to the specified position, and the second motor 14 is turned off to complete the rotation process. After that, the movement and other processes are completed through the walking arm.
