Description
Technical Field
[0001] The utility model belongs to the field of structures, and particularly relates to a prefabricated pre-constrained block material wallboard and structure. Background Art
[0002] In construction projects, structural walls are an important part of building structures. Structural walls often use reinforced concrete walls, which are composed of concrete and steel bars. This requires a large amount of stone, sand, and cement materials. According to statistics, construction stone in my country accounts for nearly 1 / 2 of the mass of concrete, and its use is widespread in many industries such as construction, transportation, and railways. It is estimated that the annual amount of stone used in construction in the country is about more than 4 billion tons, which is the material that consumes the most natural resources. At present, natural sand and gravel that meet the requirements of reinforced concrete structures can no longer meet the needs of engineering. In actual engineering, a large amount of machine-made sand and machine-made stone are used. Usually, natural stones are processed by vibrating feeders, jaw crushers, sand making machines, vibrating screens, and belt conveyors. Equipment such as conveyors are used to crush natural stones into small-sized gravel or sand. This process requires high consumption of electricity, transportation, and labor, and produces a lot of dust. This puts great pressure on our resources and environment. How to reduce the use of cement, small-sized sand, and stone in structural walls is of great significance to my country's engineering construction and energy conservation and environmental protection.

DETAILED DESCRIPTION
[0029] In order to better understand the purpose, technical solution and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings. Here, the illustrative embodiments of the utility model and their descriptions are used to explain the utility model, but are not intended to limit the utility model.
[0030] In the description of the present utility model, it is to be understood that the terms "include / comprise", "consist of..." or any other variations thereof are intended to cover non-exclusive inclusion, so that a product, device, process or method including a series of elements includes not only those elements, but also other elements not explicitly listed when necessary, or also includes elements inherent to such product, device, process or method. In the absence of further restrictions, the elements defined by the sentences "include / comprise..." and "consist of..." do not exclude the presence of other identical elements in the product, device, process or method including the elements.
[0031] In the present utility model, unless otherwise clearly specified and limited, the term "fixed connection" should be understood in a broad sense, for example: it can be a sleeve connection, a lap joint, a welding connection, a bolt connection, or a combination of the above connections; the terms "installation", "connection", "connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two components or the interaction relationship between two components; the term "through-length steel bar" means that the steel bar is continuous without disconnection, or the steel bar is disconnected but the disconnected steel bars are fixedly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0032] It should also be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device, component or structure referred to must have a specific direction, be constructed or operate in a specific direction, and should not be understood as a limitation on the present invention.
[0033] The following is a detailed description of the implementation of the present invention using preferred implementation methods in conjunction with the accompanying drawings.
[0034] like Figure 1 , Figure 2As shown, a prefabricated pre-constrained block wall panel includes a pre-constrained block 9, precast concrete 3 and wall reinforcement 5; the pre-constrained block 9 includes a block 1 and a restraining cage 2; the block 1 is built in the restraining cage 2; the restraining cage 2 includes a cage frame 2.1 and restraining cage holes 2.2; the restraining cage 2 is closed at the ends; the restraining cage 2 is a restraining bar cage or a mesh cage; the wall reinforcement 5 includes wall vertical reinforcement 5.1 and wall horizontal reinforcement 5.2; the wall horizontal reinforcement 5.2 and the wall vertical reinforcement 5.1 are arranged at intervals to form a wall reinforcement mesh 6; the pre-constrained block 9 is surrounded by the wall reinforcement mesh 6; at least one end of the wall vertical reinforcement 5.1 extends out of the precast concrete 3.
[0035] Since the utility model uses a block material 1 with a larger particle size in the prefabricated pre-constrained block wall panel, compared with ordinary concrete walls, the amount of cement and small-particle sand and gravel in the wall can be effectively reduced, which is energy-saving and environmentally friendly. When the sand and gravel in the wall are artificially graded sand and gravel, the prefabricated pre-constrained block wall panel can further reduce the high energy consumption and high dust caused by artificially graded sand and gravel.
[0036] Due to the presence of block material 1, the shrinkage creep of prefabricated pre-constrained block material wall panels is smaller than that of ordinary concrete walls, thus avoiding the defect that ordinary concrete is prone to cracks during large-volume construction. Block material 1 can greatly reduce the amount of cement used and reduce the hydration heat during construction. For large-volume concrete, hydration heat will cause concrete cracking, resulting in a decrease in the mechanical properties of concrete and a reduction in the service life of wall components. For prefabricated pre-constrained block material wall panels, hydration heat can be reduced, and block material 1 can effectively absorb the hydration heat generated by the surrounding prefabricated concrete 3, reduce the temperature difference with the surrounding area, and effectively avoid the hydration heat generated by the temperature difference.
[0037] The prefabricated pre-constrained block wall panel constrains the block material 1 in the cage and the precast concrete 3 in the constraint cage through the constraint cage 2 in the wall, thereby improving the strength and ductility of the combination of the block material 1 and the precast concrete 3 in the constraint cage, and forming a block precast concrete with a constraint effect; the constraint cage 2 simultaneously connects the precast concrete 3 in the constraint cage and the precast concrete 3 outside the constraint cage, and there is precast concrete 3 at the constraint cage hole 2.2, so that the precast concrete 3 in the constraint cage 2 and the precast concrete 3 outside the constraint cage 2 are connected as a whole; the constraint cage 2 increases the reinforcement content of the prefabricated pre-constrained block wall panel, and as a block precast concrete with a constraint effect, it bears the corresponding force, thereby realizing that the precast concrete 3 is subjected to force together with the constraint cage 2 and the wall steel bars 5 of the prefabricated pre-constrained block wall panel, and realizing the overall mechanical properties of the prefabricated pre-constrained block wall panel.
[0038] Moreover, during construction, the block material 1 is placed in the constraint cage 2 to form a pre-constrained block material 9, and multiple blocks can be hoisted and transported at one time, thereby improving construction efficiency; the constraint cage 2 can control the contact mode, contact area and shape of the block material 1 during construction, so that the precast concrete 3 can effectively fill the gaps between the blocks 1, effectively reduce quality defects, improve construction quality, and achieve structural safety.
[0039] In the utility model, Figure 2 and Figure 3 As shown, the precast concrete 3 fills the gap in the pre-constrained block 9; the precast concrete 3 wraps the wall steel mesh 6 and fills the gap between the pre-constrained block 9 and the wall steel mesh 6; there is precast concrete 3 at the constraint cage hole 2.2, so that the precast concrete 3 in the constraint cage 2 and the precast concrete 3 outside the constraint cage 2 are connected as a whole; the size of the constraint cage hole 2.2 is smaller than the size of the block 1 at that location; the cage frame 2.1 includes a side wall frame 2.1.1 and an end closure 2.1.2; the end closure 2.1.2 is formed by extending the side wall frame 2.1.1 or is a dedicated end closure 2.1.2; the dedicated end closure 2.1.2 is connected to the side wall frame 2.1.1 as a whole; the block 1 is at a certain distance from the end of the precast concrete 3, the distance is not less than 10mm; the cage 2.1 can fix the position of the block 1, and the end closure 2.1.2 can close the cage 2.1 to prevent the block 1 from falling off from the end; the end closure 2.1.2 is formed by extending the side wall frame 2.1.1, and the two are integrated, which is beneficial to improve the strength and ductility of the pre-constrained block 9; the dedicated end closure 2.1.2 and the side wall frame 2.1.1 are combined for easy production.
[0040] In the present invention, the block material 1 can be a stone, a reinforced concrete block, a concrete block or a cement mortar block.
[0041] Precast concrete 3 includes high flow concrete, fiber concrete, organic concrete and ultra-high performance concrete HEPA, etc.
[0042] High-flow concrete includes self-compacting concrete and high-flow concrete. High-flow concrete requires sufficient powder content, and the coarse aggregate can be 5-15mm or 5-25mm in particle size. High-flow concrete is more conducive to filling the gaps between blocks and ensuring the overall compactness of pre-constrained block wall panels.
[0043] In the utility model, the block material 1 and the concrete do not undergo a chemical reaction that reduces strength or durability; the surface of the block material 1 is a rough surface; the rough surface of the block material 1 is tightly combined with the concrete. The particle size of the block material is 60mm to 400mm (small block material, including 400mm), which can be used for walls of various thicknesses; 400mm to 800mm (medium block material, including 800mm), which is used for walls with a thickness greater than 500mm. The reasonable configuration of blocks of different particle sizes and walls of corresponding cross sections is conducive to improving the bearing capacity of the wall.
[0044] The mud content of the block is less than 0.7%, and it is not allowed to be concentrated in a few areas. The difference between the block particle size and the average block particle size is not more than 30% of the average particle size. The small difference in block particle size makes it easier to control the contact mode between blocks or reduce their contact area.
[0045] In the utility model, Figure 3 As shown, the restraint cage 2 is closed at both ends; the restraint cage 2 is a restraint rib cage, and the cage frame 2.1 of the restraint rib cage is composed of restraint ribs 4; the restraint ribs 4 are steel bars or steel wires or FRP bars; the cage frame 2.1 of the grid cage is composed of metal mesh or steel plates with holes; the restraint ribs 4 include longitudinal ribs 4.1, transverse ribs 4.2 and / or diagonal ribs 4.3; the end closures 2.1.2 of the restraint rib cage are formed by fixed connection or bending of the longitudinal ribs 4.1 or the diagonal ribs 4.3 at the ends or are independent end closures 2.1.2; the independent end closures 2.1.2 are fixedly connected to the longitudinal ribs 4.1 or the diagonal ribs 4.3; the fixed connection method is bolting, welding or binding connection.
[0046] The shape of the restraining cage 2 can be cylindrical, spherical, ellipsoidal, etc.
[0047] The distribution spacing of the restraining ribs 4 at the lower part of the restraining cage 2 is smaller than the distribution spacing at the upper part of the restraining cage 2; the grid size formed by the longitudinal ribs 4.1 and the transverse ribs 4.2 is smaller than the size of the block placed at the grid, preventing the block 1 from falling off.
[0048] The cage 2.1 is made of steel, and the strength of the steel is not less than 300Mpa; the volume ratio of the block 1 to the restraining cage 2 is 5% to 85%; the volume ratio of the block 1 to the precast concrete 3 is 5% to 300%; the volume ratio of the cage 2.1 to the restraining cage 2 is 0.02% to 3%. This can improve the strength and ductility of the pre-restrained block wall.
[0049] In the utility model, Figure 4 , Figure 5 As shown, the cage 2.1 has multiple sub-spaces; the sub-spaces are independent of each other and contain blocks 1. The sub-spaces are formed by the cage 2.1 being divided by block spacers 7 or external restraints or welds or restraint ribs 4; or the lateral connectors are hooped together by external restraint ribs to form multiple sub-spaces.
[0050] The multiple subspaces divide the block material into multiple parts, which can increase the bonding strength and ductility between the block material 1 and concrete, and facilitate production and transportation.
[0051] The block spacer 7 is composed of a steel mesh or a perforated steel plate, and is fixedly connected to the side wall frame 2.1.1; the gaps in the steel mesh are smaller than the size of the block 1; the hole size of the perforated steel plate is smaller than the size of the block 1; the block spacer 7 is arranged longitudinally and / or transversely and / or vertically.
[0052] In the utility model, Figure 6 , Figure 7As shown, based on Example 3, partial modifications are made as follows: there are multiple pre-constrained blocks 9; the pre-constrained blocks 9 are arranged at intervals along the lateral direction of the wall, and the precast concrete 3 fills the gaps between the pre-constrained blocks 9. Multiple pre-constrained blocks 9 can reduce the amount of precast concrete 3.
[0053] The clearance of the pre-constrained blocks 9 is not less than 20 mm and not less than the diameter of the constraint cage, which is conducive to the coordinated force of the pre-constrained blocks 9 and the precast concrete 3. Multiple pre-constrained blocks 9 can reduce the amount of precast concrete 3. In the present utility model, Figure 7 As shown, tie bars 5.3 are arranged between the wall reinforcement meshes 6; the tie bars 5.3 connect the wall reinforcement meshes 6; the tie bars 5.3 are arranged at intervals along the vertical and horizontal directions of the wall reinforcement meshes 6 to form a vertically connected space; and pre-constrained blocks 9 are placed in the vertically connected space.
[0054] In the utility model, Figure 8 As shown, a steel connector 8 is provided inside the wall reinforcement mesh 6; the steel connector 8 is a steel section or a steel member; at least one end of the steel connector 8 extends out of the precast concrete 3; there is a gap between the steel connector 8 and the pre-constrained block 9 and the wall reinforcement mesh 6; the precast concrete 3 fills the gap between the pre-constrained block 9, the steel connector 8 and the wall reinforcement mesh 6; both ends of the wall vertical reinforcement 5.1 extend out of the precast concrete 3.
[0055] In the utility model, Fig. 9 As shown, one end of the wall vertical steel bar 5.1 extends out of the precast concrete 3, and the other end is inserted into the sleeve 11; the sleeve 11 is wrapped by the precast concrete 3, exposing the grouting port and the lower hole; the sleeve 11 is a grouting sleeve or a semi-grouting sleeve.
[0056] In the utility model, the prefabricated pre-constrained block material wall panel is fixedly connected with the beam and the plate to form a prefabricated pre-constrained block material wall panel structure.

Any modifications, equivalent substitutions and improvements made by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
