The fixture block 4 is a quarter of the part of the prism, the center of which is hollowed out to form an inscribed cylinder, and is used for filling the gap between the vertical rotating rod 2 and the main transverse rod 1 and the secondary transverse rod 5 during assembly, so that the vertical rotating rod 2 can be in better contact with other components without influencing the rotation of the combination process. The clamping block 4 is made of corrosion-resistant glass fiber composite materials, and is not functional from the mechanical point of view, because the cylinder 3 is only tangent to four sides of the slotted parts on the two sides of the main cross bar and the secondary cross bar theoretically, and is not in mechanical contact with the clamping block 4, the existence of the clamping block 4 is beneficial to relieving construction errors (the clamping block cannot be completely tangent) and strengthening the integrity of a connection node.

Theoretically, the vertical rotating rod 2 can rotate at any angle without the bolt 6; in practical situations, after the 12 rod pieces are assembled, small dislocation among the rod pieces is caused under the action of gravity and frictional force and errors caused by manufacturing, installation and the like, so that the vertical rotating rod 2 is difficult to rotate, and the existence of the bolt 6 further reduces the probability of unfavorable rotation of the vertical rotating rod 2.
The utility model discloses a theory of operation does: when assembling, the main cross rod 1 is used as a splicing framework, and the vertical rotating rod 2 is used as a stress main body; firstly, fixing a main cross rod 1 by using a support, enabling an A surface to be upward, enabling a B surface to be opposite to an operator, then erecting a vertical rotating rod 2, enabling an E surface to be opposite to the operator, enabling an F surface to face the right and pushing in a leftmost slotting part of the main cross rod 1, enabling a cylinder 3 to be tangent to the leftmost slotting part of the main cross rod 1, then erecting a vertical rotating rod 2, enabling the F surface to be opposite to the operator, enabling a G surface to face the right and pushing in a rightmost slotting part of the main cross rod 1, enabling the cylinder 3 to be tangent to the rightmost slotting part of the main cross rod 1, and then repeating the operation symmetry for splicing, wherein the distance between 2 main cross rods is particularly adjusted; after the vertical rotating rod is in place, the fixture block 4 is arranged around the cylinder 3 to form a prism; then hoisting a secondary cross rod 5 to be arranged on the left side, enabling the C side to face upwards and enabling the B side to face an operator, connecting the secondary cross rod 5 to the main cross rod 1 according to the concave-convex meshing characteristics, and repeatedly installing the right secondary cross rod 5, so that the lower layer is basically assembled, the upper layer can be repeatedly assembled or flexibly assembled according to the characteristics of components and the forms of supports, and the special explanation is that the assembly sequence is closely related to the characteristics of the components and the forms of the supports, and the assembly mode is not the only assembly mode; taking fig. 2 as an example, after 12 rod pieces are in place, the vertical rotating rod 2 just opposite to and close to the left side of the operator rotates 90 degrees clockwise, the vertical rotating rod 2 just opposite to and close to the right side of the operator rotates 90 degrees anticlockwise, the rest operation is carried out by the analogy, after all the vertical rotating rods 2 are in place, all the bolts 6 are embedded into the first clamping grooves 7 and the second clamping grooves 8, and therefore the assembly of the whole novel combined type GFRP (glass fiber reinforced plastic) rib reinforced concrete artificial fish reef is completed.
In order to further optimize the scheme, the combined glass fiber reinforced concrete artificial fish reef is simulated by using abaqus software, so that the stress characteristics of the integral model of the combined artificial fish reef under the gravity load and the 1/4 model under the landing impact load are obtained, stress clouds are shown in fig. 12 and 13, and the curve of the relationship between the impact force at the bottom and the time is shown in fig. 14.
The weak position of the artificial fish reef is strengthened during the design of the cross section, and the requirements of the artificial fish reef on the stability such as impact resistance, slippage resistance, overturn resistance and the like are met. The internal force analysis of the artificial fish reef adopts plane simplification, and the distribution of bending moment M and shearing force V under the condition of different overhang ratios k is calculated, as shown in fig. 15; the anti-slip and anti-overturning safety factors for different overhang ratios k were calculated as shown in fig. 16.
Compared with the existing concrete artificial fish reef, the novel combined glass fiber reinforced concrete artificial fish reef has certain advantages, and relevant specific parameters are shown in figure 17. For the fish-trapping type fish reef, a larger flow state effect needs to be created, and the value of the ratio of the volume of the empty space to the volume of the material (parameter x) needs to be larger; for the proliferation and attachment type marine reef, it is desirable that the ratio of surface area to material volume (parameter y) be higher. The comparison shows that the x value of the novel (# -shaped) combined type glass fiber reinforced concrete artificial fish reef is the largest, and the y value is smaller but has little difference.
