Description
Technical Field
[0001] The utility model belongs to the field of structures, and particularly relates to a pre-constrained block material wall and a connection system. 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.

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.
[0033] 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.
[0034] 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.
[0035] The following is a detailed description of the implementation of the present invention using preferred implementation methods in conjunction with the accompanying drawings.
[0036] like Figure 1 , Figure 2As shown, a pre-constrained block wall includes a pre-constrained block 9, a polymer 3 and a wall steel bar 5; the pre-constrained block 9 includes a block 1 and a constraint cage 2; the block 1 is built in the constraint cage 2; the constraint cage 2 includes a cage frame 2.1 and a constraint cage hole 2.2; the constraint cage 2 is closed at the end; the wall steel bar 5 includes a wall vertical steel bar 5.1 and a wall horizontal steel bar 5.2; the wall horizontal steel bar 5.2 and the wall vertical steel bar 5.1 are arranged at intervals to form a wall steel bar mesh 6; the pre-constrained block 9 is surrounded by the wall steel bar mesh 6; the polymer 3 fills the gap in the pre-constrained block 9; there is a polymer 3 at the constraint cage hole 2.2, so that the polymer 3 in the constraint cage 2 and the polymer 3 outside the constraint cage 2 are connected as a whole.
[0037] Since the utility model uses a block material 1 with a larger particle size in the pre-constrained block material wall, 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 pre-constrained block material wall can further reduce the high energy consumption and high dust caused by the artificially graded sand and gravel.
[0038] Due to the presence of block material 1, the shrinkage creep of the pre-constrained block material wall is smaller than that of ordinary concrete wall, 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 pre-constrained block material walls, hydration heat can be reduced, and block material 1 can effectively absorb the hydration heat generated by the surrounding polymer 3, reduce the temperature difference with the surrounding area, and effectively avoid hydration heat generated by the temperature difference.
[0039] The pre-constrained block wall constrains the block 1 in the cage and the polymer 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 1 and the polymer 3 in the constraint cage, and forming a block polymer with a constraint effect; the constraint cage 2 simultaneously connects the polymer 3 in the constraint cage and the polymer 3 outside the constraint cage, and there is polymer 3 at the constraint cage hole 2.2, so that the polymer 3 in the constraint cage 2 and the polymer 3 outside the constraint cage 2 are connected as a whole; the constraint cage 2 increases the reinforcement content of the pre-constrained block wall, and as a block polymer with a constraint effect, it bears the corresponding force, so that the polymer 3, the constraint cage 2 and the wall steel bars 5 of the pre-constrained block wall are subjected to force together, thereby realizing the overall mechanical properties of the pre-constrained block wall.
[0040] 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 polymer 3 can effectively fill the gaps between the blocks 1, effectively reduce quality defects, improve construction quality, and achieve structural safety.
[0041] In the utility model, the polymer 3 wraps the wall steel mesh 6 and fills the gap between the pre-constrained block 9 and the wall steel mesh 6; tie bars 5.3 are arranged between the wall steel meshes 6; the tie bars 5.3 connect the wall steel meshes 6; the tie bars 5.3 are arranged at intervals along the vertical and horizontal directions of the wall steel mesh 6 to form a vertically connected space; the pre-constrained block 9 is placed in the vertically connected space.
[0042] The block material 1 can be a stone, a reinforced concrete block, a concrete block or a cement mortar block; the polymer 3 can be cement paste, cement mortar or concrete.
[0043] The size of the constraint cage hole 2.2 is smaller than the size of the block material 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 cage frame 2.1 can fix the position of the block material 1, and the end closure 2.1.2 can close the cage frame 2.1 to prevent the block material 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 improving the strength and ductility of the pre-constrained block material 9; the dedicated end closure 2.1.2 and the side wall frame 2.1.1 are combined for easy manufacturing.
[0044] In the utility model, the block material 1 and the polymer 3 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 polymer 3. 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.
[0045] 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.
[0046] In the utility model, Figure 3 As shown, the restraint cage 2 is a restraint bar cage, and the cage frame 2.1 of the restraint bar cage is composed of restraint bars 4; the restraint bars 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.
[0047] The restraining 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 restraining 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.
[0048] The shape of the restraining cage 2 can be cylindrical, spherical, ellipsoidal, etc.
[0049] 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.
[0050] In the utility model, the block material 1 is a stone; the polymer 3 is a high-flow concrete; the high-flow concrete includes self-compacting concrete and high-flow concrete. The high-flow concrete requires a sufficient amount of powder content, and the coarse aggregate can be 5-15mm or 5-25mm in particle size. The high-flow concrete is more conducive to filling the gaps between the blocks and ensuring the overall compactness of the pre-constrained block wall.
[0051] 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 polymer 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.
[0052] 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.
[0053] The multiple subspaces divide the block material into multiple parts, which can increase the bonding strength and ductility between the block material 1 and the polymer 3 and facilitate production and transportation.
[0054] 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.
[0055] In the utility model, Figure 6 , Figure 7 As shown, there are a plurality of pre-restrained blocks 9; the pre-restrained blocks 9 are arranged at intervals along the transverse direction of the wall.
[0056] The clearance of the pre-constrained block 9 is not less than 0.30 times the cross-sectional diameter of the pre-constrained block 9 .
[0057] In the utility model, Figure 8 As shown, a steel frame 8 is provided inside the wall reinforcement mesh 6; the steel frame 8 is a steel section or a steel component; there is a gap between the steel frame 8 and the pre-constrained block material 9 and the wall reinforcement mesh 6; the polymer 3 fills the gap between the pre-constrained block material 9, the steel frame 8 and the wall reinforcement mesh 6.
[0058] In the utility model, Fig. 9 As shown, a connection system of a pre-constrained block wall includes a pre-constrained block wall A and a reinforced concrete slab B; the pre-constrained block wall A is fixedly connected to the reinforced concrete slab B to form a wall panel node area; there is no pre-constrained block material 9 in the wall panel node area; the reinforced concrete slab B has a slab longitudinal steel bar, a slab transverse steel bar and a slab concrete; the slab longitudinal steel bar and the slab transverse steel bar are arranged at intervals to form a slab steel bar mesh; the slab longitudinal steel bar extends into the pre-constrained block wall A, is located between the wall vertical steel bar 5.1, the wall horizontal steel bar 5.2 and the pre-constrained block material 9, and is wrapped by the polymer 3 of the pre-constrained block wall A.
[0059] In the utility model, Fig.10 As shown, a connection system of a pre-constrained block wall includes a pre-constrained block wall A and a beam C; the pre-constrained block wall A is fixedly connected to the beam C to form a shear wall structure; there is no pre-constrained block 9 in the wall-beam node area; there is a hidden column at the pre-constrained block wall A corresponding to the beam C; the beam C is a reinforced concrete beam or a steel-framed concrete beam; the reinforced concrete beam includes longitudinal reinforcement, transverse reinforcement and concrete; the longitudinal reinforcement of the reinforced concrete beam is inserted into the pre-constrained block wall A, located between the vertical reinforcement 5.1 of the wall, the horizontal reinforcement 5.2 of the wall and the pre-constrained block 9, and is wrapped by the polymer 3 of the pre-constrained block wall A; the steel-framed concrete beam includes longitudinal reinforcement, transverse reinforcement, beam steel frame and concrete; the longitudinal reinforcement of the steel-framed concrete beam is inserted into the pre-constrained block wall A, located between the vertical reinforcement 5.1 of the wall, the horizontal reinforcement 5.2 of the wall and the block 1, the beam steel frame is connected to the embedded parts or steel connecting parts in the pre-constrained block wall A, and the longitudinal reinforcement and the beam steel frame are wrapped by the polymer 3 of the pre-constrained block wall A in the wall-beam node area.
