In a specific embodiment, the concrete wall with the restrained shear-resistant bars and the hooked connection nodes comprises a steel plate 11 and a wall body 12 formed by pouring concrete, wherein the steel plate 11 is positioned on one side of the wall body 12, a reinforcing mesh 13 which is parallel to the steel plate 11 and matched with the steel plate 11 in a contraposition mode is embedded on the other side of the wall body 12, and main extension surfaces of the steel plate 11, the wall body 12 and the reinforcing mesh 13 are parallel to each other; the reinforcing mesh 13 is provided with a plurality of transverse constraint shear resistant ribs 131, the transverse constraint shear resistant ribs 131 are linked with the reinforcing mesh 13 in the direction perpendicular to the main extension surface of the steel plate 11, a plurality of hook connectors 111 are uniformly distributed on the main extension surface of one side of the steel plate 11 facing the wall 12 in an array manner, and free ends of the transverse constraint shear resistant ribs 131 are provided with hooks 132 connected with the hook connectors 111 in an alignment manner.
During construction, in a factory, the hook connectors 111 are welded and fixed on the steel plate 11 in an aligned mode in advance, the hook connectors 111 are guaranteed to be evenly distributed on the same side of the steel plate 11 in an array mode, then the steel plate 11 assembled with the hook connectors 111 is conveyed to a construction site, each transverse restraint shear bar 131 which is processed and formed is assembled on the reinforcement mesh 13 which is bound and formed in an aligned mode, the hooks 132 are connected to the corresponding hook connectors 111 in an aligned mode, the reinforcement mesh 13, the transverse restraint shear bars 131 and the steel plate 11 are reliably assembled to form prefabricated components, then formwork supporting can be carried out at an operation face where concrete wall pouring construction with restraint shear bars and hook connecting nodes is required, after formwork supporting is finished, the assembled prefabricated components are placed at the formwork supporting positions, the steel plate 11 and a supported foundation formwork are arranged on the opposite side to form a pouring mold, and then concrete pouring is carried out, and filling the inner cavity of the casting mold with concrete, particularly filling the space between the steel plate 11 and the reinforcing mesh 13, fully immersing the reinforcing mesh 13, and solidifying and hardening to complete the forming construction operation of the concrete wall with the restrained shear-resistant ribs and the hook connecting nodes. The steel plate 11 pre-assembled with the hook connector 111 and the transverse constraint shear bar 131 in a factory are assembled on site in the whole operation process to realize reliable assembly among the steel bar mesh 13, the transverse constraint shear bar 131 and the steel plate 11, after a concrete wall with constraint shear bars and hook connecting nodes is poured and formed, the integral tensioning limit of the concrete wall with the constraint shear bars and the hook connecting nodes is realized by utilizing the hooking structure between the transverse constraint shear bar 131 and the hook connector 111 and the embedded and embedded structure between the steel bar mesh 13 and the wall body 12, the structural strength and the shearing resistance of the concrete wall with the constraint shear bars and the hook connecting nodes are greatly improved, meanwhile, the site construction process of the concrete wall with the constraint shear bars and the hook connecting nodes is effectively simplified, the site construction difficulty and the operation amount are reduced, and the labor intensity of workers is reduced, the whole engineering operation efficiency of the concrete wall with the constraint shear-resistant ribs and the hook connecting nodes is correspondingly improved.
It should be noted that, the assembly method of the hook 132 and the hook alignment hook connection between the lateral constraint shear rib 131 and the hook connection member 111 is simple and easy, and the structural connection strength is also good, but the assembly method between the lateral constraint shear rib 131 and the steel plate 11 is not limited thereto, and under the premise that the process conditions and the assembly space are allowed, the multi-point alignment connection assembly structure between the lateral constraint shear rib 131 and the steel plate 11 can be realized by using the lock catch and the lock hole to be inserted and locked or using the interference locking structure between the alignment mating members. The worker can completely adjust the assembly structure form between the transverse constraint shear rib 131 and the steel plate 11 according to the actual working condition requirement and the process condition, and in principle, the concrete wall with the constraint shear rib and the hook connecting node can be formed and constructed as long as the strength of the assembly structure between the transverse constraint shear rib and the steel plate can be ensured and the requirements of the concrete wall with the constraint shear rib and the hook connecting node can be met.
In addition, it should be pointed out that, combine the figure to know, the quantity of hook connecting piece 111 on the steel sheet 11 is more, it is comparatively intensive to arrange, but the quantity of the anti shear reinforcement 131 of horizontal restraint need not to be the same with hook connecting piece 111 and counterpoint one by one, only need under the prerequisite of guaranteeing assembly strength, the array interval of arranging that corresponds hook connecting piece 111 sets up the anti shear reinforcement 131 of horizontal restraint and couple 132 that multirow and/or multiseriate were evenly arranged can, so, can suitably reduce whole construction cost and the operation degree of difficulty, optimize process flow, thereby further improve whole efficiency of construction.
It should be understood that the main extension plane of the steel plate 11 mentioned above refers to the extension direction of the plane where each of a group of symmetry planes with the largest area on the outer surface of the steel plate 11 is located or the extension directions of the other planes parallel to the plane, and it is obvious that in actual assembly and application, the main extension planes of the wall 12 and the reinforcing mesh 13 are both parallel to the main extension plane of the steel plate 11, and therefore, the extension directions of the main extension planes of the three are also the same. The description of the main extension plane of the steel plate 11 mentioned in the rest of the text can be understood with reference to this description and will not be described in detail.
Further, the lateral restraint shear rib 131 includes a lateral extension 1311 extending in a direction parallel to the main extension surface of the steel plate 11, the lateral extension 1311 abuts against the outside of the steel mesh 13 in a direction perpendicular to the main extension surface of the steel plate 11, both ends of the lateral extension 1311 are respectively provided with a longitudinal extension 1312 passing through the steel mesh 13 from the side of the steel mesh 13 to the side of the steel plate 11 in the direction perpendicular to the main extension surface of the steel plate 11 and aligned with each hook connector 111, and the hooks 132 are respectively disposed at the free ends of each longitudinal extension 1312. The transverse extension section 1311 can form structural linkage with the transverse restraint shear bar 131, so that on the basis that the longitudinal extension section 1312 is reliably assembled with the steel plate 11 through the hook 132, the integral tensioning and limiting effects on the reinforcing mesh 13 and even the wall body 12 in the direction perpendicular to the main extension face of the steel plate 11 are fully guaranteed, the integral structural strength and the impact resistance of the concrete wall with the restraint shear bar and the hook connecting node are guaranteed, and the use requirements after actual construction and building forming are met.
It should be understood that, in the specific assembly application, the transverse extension 1311 is not limited to the straight configuration shown in the figures, but may also be an arc configuration or a partially wavy configuration adapted to the mesh reinforcement 13, however, regardless of the specific configuration, the transverse extension 1311 extends in a direction substantially along the main extension plane of the steel plate 11 to ensure the assembly alignment effect between the corresponding adapter members.
In addition, the lateral restraint shear ribs 131 may be rod-shaped reinforcing bars extending in a direction perpendicular to the main extension plane of the steel plate 11, and the hooks 132 are provided at the free ends of the lateral restraint shear ribs 131 in a one-to-one correspondence. The rod-shaped reinforcing steel bar structure is simpler and more reliable, the structure of the transverse restraint shear bar 131 and the corresponding assembly process can be further simplified, and the whole construction cost can be correspondingly reduced.
Accordingly, regardless of the structure of the transverse restraining shear bar 131, it can be welded to the mesh reinforcement 13 to further ensure the assembling strength.
Specifically, if the laterally-constrained shear bar 131 is formed by matching the laterally-extended segments 1311 with the longitudinally-extended segments 1312, the laterally-constrained shear bar 131 and the mesh reinforcement 13 can be integrally assembled and fixed by welding the laterally-extended segments 1311 with the mesh reinforcement 13; if the transverse restraining shear bar 131 is in the form of a rod-shaped steel bar, the connecting segment of the transverse restraining shear bar 131, i.e. the end where the hook 132 is not assembled, can be directly welded to the mesh reinforcement 13, so as to achieve reliable fixation between the transverse restraining shear bar 131 and the mesh reinforcement 13. The staff can be according to actual conditions and the concrete structure of corresponding part nimble welding assembly position of selecting and the operation mode.
On the other hand, the hooks 132 are bent in the same direction. The bending direction of each hook 132 is consistent, and the alignment connection operation between each hook 132 and the corresponding hook connecting piece 111 can be completed by single hook operation, so that the operation difficulty is greatly reduced, and the construction efficiency is improved.
Accordingly, each hook connecting piece 111 can be bent moderately in the direction in which the hook 132 performs hooking connection, so as to further reduce the difficulty of alignment connection between the hook 132 and the hook connecting piece 111, and improve the alignment accuracy and the assembly efficiency of the hook 132 and the hook connecting piece 111.
More specifically, the bending angle of the hook 132 is 90-135 degrees, and the span of the hook 132 is 5-12 times of the diameter. The span of the hook 132 herein refers to the distance between the axes of the two parallel ends of the hook 132. Here, the bending angle and the span size of the hook 132 are set in consideration of general working condition requirements and general steel bar structural member size standards, in practical application, a worker can flexibly adjust structural parameters such as the bending angle and the span size of the hook 132 according to specific working condition requirements, and in principle, the concrete wall with the constraint shear-resistant rib and the hook connecting node can be constructed as long as the alignment assembly of the hook 132 and the hook connecting member 111 can be ensured and the concrete construction requirements of the concrete wall with the constraint shear-resistant rib and the hook connecting node can be met.
