Description

Technical Field

[0001] The utility model belongs to the field of structures, and in particular relates to a pre-constrained block plate and a connection node. Background Art

[0002] In construction projects, structural panels are an important part of building structures. Structural panels often use reinforced concrete panels, 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 panels is of great significance to my country's engineering construction and energy conservation and environmental protection.

[0009] Preferably, the cage has a plurality of sub-spaces; the sub-spaces are independent of each other and contain blocks of materials.

[0010] Preferably, there are multiple pre-constrained blocks; the pre-constrained blocks are arranged at intervals along the longitudinal and / or transverse direction of the plate; the restraint cage is placed horizontally; the pre-constrained block plate has tie bars, a steel mesh on the tie plate and a steel mesh under the plate, and the tie bars are located between the pre-constrained blocks.

[0011] Preferably, the plate reinforcement includes non-prestressed reinforcement and prestressed reinforcement; the prestressed reinforcement is located between the pre-constrained blocks and is wrapped by a polymer.

[0012] A connection node of a pre-constrained block plate comprises a pre-constrained block plate and a reinforced concrete beam; the pre-constrained block plate is fixedly connected to the reinforced concrete beam to form a beam-plate node area; the reinforced concrete beam has longitudinal steel bars, transverse steel bars and beam concrete; the transverse steel bars of the beam are arranged at intervals along the longitudinal direction of the beam; the plate steel bars extend into the reinforced concrete beam, are located in the gap between the transverse steel bars and the longitudinal steel bars of the beam, and are wrapped by the beam concrete; the pre-constrained block material is at a certain distance from the edge of the beam.

Block materials 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 mechanical properties such as concrete compression resistance, and reduce the service life of the board components. For pre-constrained block polymer filled boards with a block material ratio of 25%, the hydration heat can be reduced by more than 25%, and the block material can effectively absorb the hydration heat generated by the surrounding filler, reduce the temperature difference with the surrounding area, and effectively avoid the hydration heat generated by the temperature difference.

DETAILED DESCRIPTION

[0031] 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.

[0032] 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.

[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 2 As shown, a pre-constrained block plate, the pre-constrained block plate A includes a pre-constrained block 9, a polymer 3 and a plate 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 constraint cage 2 is a constraint bar cage or a mesh cage; the plate steel bar 5 includes a plate longitudinal steel bar 5.1 and a plate transverse steel bar 5.2; the plate transverse steel bar 5.2 and the plate longitudinal steel bar 5.1 are arranged at intervals to form a plate steel bar mesh 6; the plate steel bar mesh 6 has a plate steel bar mesh 6.1 and a plate lower steel bar mesh 6.2; the pre-constrained block 9 is located between the plate upper steel bar mesh 6.1 and the plate lower steel bar mesh 6.2; the polymer 3 fills the gap in the pre-constrained block 9; the polymer 3 wraps the plate steel bar mesh 6 and fills the gap between the pre-constrained block 9 and the plate steel bar mesh 6; 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 board, compared with ordinary concrete boards, the amount of cement and small-particle sand and gravel in the board can be effectively reduced, which is energy-saving and environmentally friendly. When the sand and gravel in the board are artificially graded sand and gravel, the pre-constrained block material board can further reduce the high energy consumption and high dust caused by artificially graded sand and gravel.

[0038] Due to the presence of block material 1, the shrinkage creep of the pre-constrained block material board is smaller than that of ordinary concrete board, 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, the hydration heat will cause concrete cracking, resulting in a decrease in the mechanical properties of concrete and a reduction in the service life of the board components. For pre-constrained block material boards, the hydration heat can be reduced, and the 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 the hydration heat generated by the temperature difference.

[0039] The pre-constrained block plate constrains the block material 1 in the cage and the polymer 3 in the constraint cage through the constraint cage 2 in the plate, thereby improving the strength and ductility of the combination of the block material 1 and the polymer 3 in the constraint cage, and forming a block material 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 plate, and as a block material polymer with a constraint effect, it bears the corresponding force, so that the polymer 3, the constraint cage 2 and the steel bars of the pre-constrained block plate are subjected to force together, and the overall mechanical properties of the pre-constrained block plate are achieved.

[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 restraining cage 2 is closed at the end; the size of the restraining 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 special end closure 2.1.2; the special 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 special end closure 2.1.2 is combined with the side wall frame 2.1.1 for easy manufacturing.

[0042] The pre-constrained block 9 is located in the middle area of ​​the board cross-section height, and the distance between the pre-constrained block 9 and the upper and lower surfaces of the board is not less than 10% of the board height, so as to realize the bending resistance of the board.

[0043] Block material 1 and polymer 3 do not undergo chemical reactions that reduce strength or durability; the surface of block material 1 is rough; the rough surface of block material 1 is tightly bonded to polymer 3. The particle size of the block material is 60mm to 400mm (small block material, including 400mm), which can be used for boards of various thicknesses; 400mm to 800mm (medium block material, including 800mm), which is used for boards with a thickness greater than 500mm. Reasonable configuration of blocks of different particle sizes and boards of corresponding cross sections is conducive to improving the bearing capacity of the board.

[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 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.

[0046] 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.

[0047] The shape of the restraining cage 2 can be cylindrical, spherical, ellipsoidal, etc.

[0048] 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.

[0049] In the utility model, the block material 1 is an old reinforced concrete block or an old concrete block, which is located in the middle of the board and has little effect on the mechanical properties of the board, and can be recycled.

[0050] Polymer 3 is high-flow concrete, which 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 the pre-constrained block board.

[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 constraint 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 constraint cage 2 is 0.02% to 3%. This can improve the strength and ductility of the pre-constrained block plate.

[0052] In the utility model, Figure 4 , Figure 5As 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 multiple pre-constrained blocks 9; the pre-constrained blocks 9 are arranged at intervals along the longitudinal and / or transverse directions of the board; the restraint cage 2 is placed horizontally; the pre-constrained block board A has tie bars, a tie plate upper steel mesh 6.1 and a board lower steel mesh 6.2, and the tie bars are located between the pre-constrained blocks 9. Multiple pre-constrained blocks 9 can reduce the amount of polymer 3 used.

[0056] The pre-constrained block 9 is usually arranged parallel to the force direction to avoid the force transmission path being cut off, thereby achieving its mechanical properties.

[0057] The clearance of the pre-constrained block material 9 is not less than 0.30 times the cross-sectional diameter of the pre-constrained block material 9 , so as to facilitate the close combination of the polymer 3 and the pre-constrained block material 9 .

[0058] In the utility model, the plate reinforcement 5 includes non-prestressed reinforcement and prestressed reinforcement; the prestressed reinforcement is located between the pre-constrained blocks 9 and is wrapped by the polymer 3 .

[0059] In the utility model, Figure 8 As shown, a connection node of a pre-constrained block plate includes a pre-constrained block plate A and a reinforced concrete beam B; the pre-constrained block plate A is fixedly connected to the reinforced concrete beam B to form a beam-slab node area; the reinforced concrete beam B has longitudinal steel bars, transverse steel bars and beam concrete; the transverse steel bars of the beam are arranged at intervals along the longitudinal direction of the beam; the plate steel bars 5 extend into the reinforced concrete beam B, are located in the gap between the transverse steel bars and the longitudinal steel bars of the beam, and are wrapped by the beam concrete; the pre-constrained block material 9 is not less than 50 mm away from the beam edge, so as to realize the shear bearing capacity of the plate end.

[0060] In the utility model, Fig. 9As shown, a connection node of a pre-constrained block plate includes a pre-constrained block plate A and a wall C; the pre-constrained block plate A is fixedly connected to the wall C; the wall C is a reinforced concrete wall, a steel-framed concrete wall or a multi-cavity steel tube concrete wall or a double steel plate concrete shear wall; the reinforced concrete wall has vertical wall steel bars, horizontal wall steel bars and wall concrete; the horizontal wall steel bars are arranged at intervals along the vertical direction of the wall; the plate steel bars 5 extend into the reinforced concrete wall, are located in the gap between the vertical wall steel bars and the horizontal wall steel bars, and are wrapped by the wall concrete; the steel-framed concrete wall has vertical wall steel bars, horizontal wall steel bars, wall steel frames and wall concrete; the plate steel bars 5 extend into the steel-framed concrete wall, are located in the gap between the vertical wall steel bars, horizontal wall steel bars and the wall steel frames, and are wrapped by the wall concrete; the steel plate of the multi-cavity steel tube concrete wall or the double steel plate concrete shear wall is welded to the plate steel bars 5; the pre-constrained block material 9 is not less than 50 mm away from the wall edge, so as to realize the shear bearing capacity of the plate end.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. 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.
