Description

Technical Field

[0001] This invention relates to the field of construction, and more particularly to a fully prefabricated water tank insulation wall panel system suitable for large volumes. Background Technology

[0002] Clear water tanks, as water storage and regulation structures, are an important component of water supply plants. With national economic development and population growth, water supply plants are expanding, and the volume of clear water tanks is also increasing. The construction of clear water tanks is a highly technical and demanding hydraulic engineering project. Currently, clear water tank wall panels are mostly constructed using traditional reinforced concrete or brick structures, which have poor insulation performance and result in energy loss of water temperature during use. This not only wastes resources but also affects the effectiveness of future water temperature control. Therefore, insulation of clear water tanks is crucial. Insulation can effectively reduce water temperature energy loss and heating costs, improving the efficiency of clear water tank use and achieving energy conservation. Fully prefabricated construction offers modular, standardized, and large-scale production technologies and standardized splicing processes. Under the condition of meeting certain strength and stability requirements, it shortens the construction period, improves construction efficiency, saves project investment, and protects the ecological environment. Therefore, it is necessary to invent a fully prefabricated insulated water tank wall panel system suitable for large-volume clear water tank construction to meet the needs of large-volume clear water tank construction.

[0003] The wall panels adopt a novel densely ribbed composite structure, replacing the masonry portion with a high-insulation-performance filling material, enabling integrated insulation. Currently available water tank wall panels have limited lateral pressure resistance and low out-of-plane stiffness, making them unsuitable for projects with deep pools and high bending load requirements. Furthermore, common prefabricated water tank splicing methods primarily involve wet connections, which are complex and inefficient. This invention addresses these engineering needs and problems by proposing a fully prefabricated water tank insulation wall panel system suitable for large-volume applications. Summary of the Invention

[0004] This invention proposes a fully prefabricated water tank insulation wall panel system suitable for large volumes, including an upper prefabricated wall panel 1, prefabricated columns 3, a lower prefabricated wall panel 2 and panel-column connection nodes, connection nodes 5 between adjacent prefabricated wall panels on the same floor, and connection nodes 6 between adjacent prefabricated wall panels between floors; the thickness of the prefabricated wall panel is related to its stress characteristics, the lateral pressure on the lower prefabricated wall panel 2 is greater than that on the upper prefabricated wall panel 1, therefore the thickness of the lower prefabricated wall panel 2 is greater than that of the upper prefabricated wall panel 1;

[0005] The precast wall panel adopts a novel dense-ribbed composite structure. The wall panel is composed of a mesh-like cavity structure formed by two side panels and several longitudinal ribs 13, transverse ribs 12, frame columns, and frame beams 16 on the inner side of the wall panel. Lightweight filling blocks 14 are placed in the cavities. The filling blocks are made of lightweight thermal insulation materials such as rock wool and foam board, which can reduce the self-weight of the wall panel and improve its thermal insulation performance. The two side panels of the wall panel are made of fiber fabric reinforced cement-based composite material to meet the requirements of bending resistance and crack resistance. Transverse through-holes 52 are opened in the transverse ribs for subsequent wall panel connection nodes on the same floor. The longitudinal ribs are made of plain concrete or ceramsite concrete. The precast columns are made of ordinary reinforced concrete structure.

[0006] The precast wall panel has square holes 51 at the intersection of each rib beam and the central rib column on the backwater side. The length of the square hole 51 should be less than the length of the rib column 13, the height should be less than the height of the rib beam 12, and the depth should reach the middle of the rib beam / column thickness. A transverse through-hole 52 with a diameter of 30mm is provided from the square hole 51 to the side of the wall panel for connecting the prestressed steel strands 53 to the wall panel of the same layer. The transverse through-hole 52 is located in the middle of the transverse rib beam 12. A longitudinal through-hole 61 is provided from the bottom groove 51 of the wall panel to the lower part of the wall panel. A longitudinal through-hole 61 is provided from the top groove 51 of the wall panel to the upper part of the wall panel. The longitudinal through-hole 61 is located in the middle of the longitudinal rib 13 and is used for the threaded connection steel rod 63 to connect the upper and lower wall panels. A prefabricated steel box 62 is placed in the bottom groove 51 and the upper groove 51 of the wall panel. The length and width of the prefabricated steel box 62 are the same as the square hole 51 of the wall panel, and the depth is less than the square hole 51 of the wall panel. The prefabricated column has a prefabricated column transverse through-hole 44 at the position corresponding to the transverse through-hole 52 of the wall panel. The two are the same size.

[0007] The slab-column connection node includes a precast wall panel side connection groove 42 and a T-shaped precast column flange protrusion 41, which are connected in a mortise and tenon joint manner; wherein the size of the connection groove 42 on the side of the precast wall panel is slightly larger than that of the flange protrusion 41 of the precast column; there is a gap between the connection groove and the protrusion, and the gap is filled with waterproof material 43;

[0008] The same-layer wall panel connection node includes a wall panel square hole 51, a wall panel transverse through hole 52, a prestressed steel strand 53, a friction plate and a nut 55; during connection, the prestressed steel strand 53 is inserted into the precast column transverse through hole 44 and the wall panel transverse through hole 52, and the ends are anchored with anchors to complete the connection of the same-layer wall panels.

[0009] The interlayer adjacent prefabricated wall panel connection node includes a wall panel square hole 51, a prefabricated steel box 62, a threaded connecting steel bar 63, a wall panel square hole 51, a pre-set longitudinal channel 61 in the wall panel, a friction plate, and a nut 55. During connection, the threaded connecting steel bar 63 is inserted into the pre-reserved longitudinal channel 61 of the upper and lower wall panels, and passes out through the longitudinal bolt hole 621 of the prefabricated steel box. The end is fixed by the friction plate and the nut 55 to complete the interlayer wall panel connection. The prefabricated steel box 62 connects the same-layer connection node and the interlayer connection node, thereby enhancing the integrity of the wall panel.

[0010] The length and width of the prefabricated steel box 62 are the same as the square hole 51 of the wall panel. Bolt holes are opened in the horizontal and vertical directions. The size of the horizontal bolt hole 622 should be larger than the size of the horizontal through hole 52 of the wall panel, and the size of the vertical bolt hole 621 should be larger than the size of the vertical through hole 61 of the wall panel. The centroids of the horizontal bolt hole 622 of the prefabricated steel box and the horizontal through hole 52 of the wall panel are the same, and the centroids of the vertical bolt hole 621 of the prefabricated steel box and the vertical through hole 61 of the wall panel are the same.

[0011] Preferably, in order to reduce costs and achieve the highest cost-effectiveness while meeting the stress requirements, the number of splicing operations of the slab-column nodes and adjacent wall panel nodes 5 on the same floor can be reasonably arranged according to the actual engineering needs; and prefabricated steel boxes 62 are placed only in the bottom groove 51 and the top groove 51 to connect the same-floor connection nodes 5 and the inter-floor connection nodes 6.

[0012] Preferably, the transverse through-hole 52 is interrupted at the square hole 51 of the wall panel, which facilitates the transverse connection of the wall panels on the same layer during construction, reduces the requirements for wall panel positioning, and prevents the problem that the transverse through-holes 52 of each wall panel cannot be aligned due to inaccurate wall panel positioning, thus making it impossible to connect.

[0013] Advantages and effects:

[0014] The present invention has the following advantages and beneficial effects:

[0015] 1) The prefabricated wall panels adopt a new type of dense rib composite structure and are filled with materials with good thermal insulation performance. The wall panel system has good thermal insulation and energy-saving effect, realizing the integration of wall insulation.

[0016] 2) The wall panels are connected by precast columns, which can improve the lateral pressure resistance and out-of-plane stiffness of the wall panels without increasing the wall panel thickness and reinforcement ratio;

[0017] 3) The wall panels in the same layer are connected by prestressed steel strands, and pressure is applied to them in advance to resist the circumferential eccentric tension caused by the lateral pressure generated by the liquid in the pool, which can effectively improve the stress performance of the wall panel system.

[0018] 4) Steel boxes are used to connect the joints between wall panels in the same layer and between wall panels in different layers, thereby improving the stability of the wall panel system;

[0019] 5) All connection nodes of this wall panel adopt dry connection, which reduces wet work on the construction site and facilitates construction management;

[0020] 6) All components are prefabricated, so if problems arise later, only the damaged components need to be replaced, which facilitates maintenance;

[0021] 7) Adopting fully prefabricated construction reduces construction time, pollution, and costs, achieving industrialization and modularization. Attached Figure Description

According to the actual project requirements, the number of splicing times of the slab-column joint and the adjacent wall panel joint 5 on the same floor are reasonably arranged; the precast wall panels and precast columns are initially connected by a mortise and tenon structure, in order from left to right.
