Description

Technical Field

[0001] This invention relates to the field of building structure technology, specifically to a protective layer combination spacer template with damping structure and a building frame structure. Background Technology

[0002] In recent years, construction projects exceeding one million square meters in scale have become increasingly common. Due to the massive scale and huge investment of these projects, there are strict requirements for construction quality, as well as high demands for controlling material and time costs.

[0003] Currently, my country's design standard for the durability of the main structure of super-large buildings is typically 100 years. Among the many technical indicators related to building durability evaluation, controlling concrete cracking and preventing the width of cracks in concrete components from exceeding the standard throughout the building's lifespan is undoubtedly of paramount importance.

[0004] To enhance the durability of the main building structure and extend its service life, it is usually necessary to adopt necessary anti-cracking techniques for concrete structures during the construction phase.

[0005] In the past, anti-cracking techniques in the construction of large public buildings in my country mainly included using high-strength steel bars (Grade IV steel, 500MPa) and increasing the reinforcement ratio of frame beams. Although these measures can effectively reduce cracks, the strength of the steel bars only accounts for about one-third of the crack width when theoretically calculating it. This results in a significant increase in steel usage, but the anti-cracking effect is not obvious and does not conform to the design concept of "strong columns and weak beams".

[0006] In ultra-large span reinforced concrete frame structures, localized stress concentration occurs at the junctions of concrete floor slabs with frame beams and columns. This manifests as abrupt changes in the shape of the concrete frame structure due to stress peaks in this area. Over time, this can lead to fatigue cracks or brittle failure of the concrete frame structure, reducing the building's service life.

[0007] Currently, the main technical measures to address the failure of concrete frame structures caused by localized stress are to increase the braiding density of the reinforcing steel in the frame, and to use high-ductility materials, such as ECC (engineered cementitious composites), in areas prone to stress peaks.

[0008] Increasing the braiding density of the reinforcing steel frame will result in increased steel consumption. With denser reinforcement, it is difficult to guarantee construction quality, and the contradiction between structural durability and material and time cost control becomes prominent.

[0009] However, the use of high-ductility materials is not only more expensive, but also involves significantly different construction processes compared to ordinary concrete structures, thus limiting their application. Currently, the main applications of high-ductility materials such as ECC are limited to structural reinforcement and renovation. The specific construction method involves overlapping the ECC with the ordinary concrete interface, with both sharing the burden of fatigue cracking or brittle failure.

[0010] Taking ECC as an example, engineering practice shows that the method of using ECC to overlap with ordinary concrete is difficult to meet the stress requirements of the peak stress zone of ultra-large span concrete frame structures. There is a problem of discontinuity between ECC and ordinary concrete in the peak tensile stress zone. Moreover, in order to make the interface between ECC and ordinary concrete overlap well, the workload of roughening the surface of ordinary concrete is very large, and the effect is difficult to control.

[0011] While fully leveraging the superior properties of high-ductility materials, eliminating the discontinuity between high-ductility materials and ordinary concrete in the peak tensile stress region, and reducing the cost of high-ductility materials and construction costs are key technical challenges that those skilled in the art need to address when dealing with fatigue cracks or brittle failures in ultra-large span concrete frame structures.

[0064] The following is in conjunction with the appendix Figures 1-16 The technical solution of the present invention will be described in detail below. The accompanying drawings constitute a part of the present invention and, together with the embodiments of the present invention, are used to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0065] This embodiment is configured as follows:

[0066] 1. The direction perpendicular to the ground is called the top; for each component set on the concrete floor slab 100 and the frame beam 200, the end of the component closer to the frame column 300 is called the near end, and the end farther away from the frame column 300 is called the far end; the side of each component facing the building surface is called the outer side, and the side away from the building surface is called the inner side; the side closer to the central axis is called the inner side, and the side farther away from the central axis is called the outer side.

[0067] 2. The internal frame is located inside the overall building frame structure; the side frame is located on the side facade of the overall building frame structure; the corner frame is located at the corner of the overall building frame structure; and the top frame is located at the top of the overall building frame structure.

[0068] 3. The cross-sections of frame beam 200 and frame column 300 are square; the side length of the cross-section of frame beam 200 is M, and the side length of the cross-section of frame column 300 is N.

[0069] 4. The thickness of the concrete floor slab 100 is H1, the thickness of the first protective layer occupant 121 of the upper frame column is H2, and the length of the first protective layer occupant 121 of the upper frame column is S.

[0070] 5. The high ductility material used in this embodiment is ECC.

[0071] During the construction process, after the steel reinforcement skeleton of the building made of stirrups is completed, a formwork box needs to be installed on the outside of the steel reinforcement skeleton. The formwork box is composed of spliced ​​formwork panels.

[0072] The protective layer combination spacer template with damping structure involved in Embodiment 1 of this invention is a structure separately set between the inner wall surface of each mold box plate and the stirrups of the steel reinforcement skeleton. After the mold box with the protective layer combination spacer template with damping structure is installed is completed, concrete can be poured. After the concrete is poured and the mold box and the protective layer combination spacer template with damping structure inside the mold box are successively removed, the protective layer clearance parts with damping structure are formed at the junction of the concrete floor slab 100 and the frame beam 200 and frame column 300 on the building concrete structure. This allows for the next step of constructing the ECC protective layer on the protective layer clearance parts, ultimately forming the building frame structure with damping structure protective layer of Embodiment 2 of this invention.

[0073] Example 1

[0074] A protective layer combination spacer template with a damping structure.

[0075] like Figures 1-10As shown, Embodiment 1 discloses a protective layer combination formwork with a damping structure used in the construction process inside a building frame structure. The protective layer combination formwork with a damping structure is used to adhere to the inner wall of the formwork used for pouring concrete, forming a concrete clearance section at the intersection of the concrete floor slab 100, frame beam 200, and frame column 300 inside the building frame structure. ECC material is then applied at the concrete clearance section to form a damping ECC protective layer on the reinforced concrete frame structure.

[0076] The structure of the protective layer combination occupant template with damping structure used on the sides and corners of the building frame structure is a modified design of the protective layer combination occupant template with damping structure disclosed in Embodiment 1.

[0077] like Figure 1 As shown, the protective layer combination spacer template with damping structure in this embodiment 1 includes an upper protective layer spacer 1 and a lower protective layer spacer 2. The damping structure includes a damping spacer and a stirrup keyway.

[0078] The upper protective layer occupant 1 and the lower protective layer occupant 2 are positioned at corresponding locations on the upper and lower surfaces of the concrete floor slab 100. The protective layer combination occupant formwork with damping structure includes four upper protective layer occupants 1 and four lower protective layer occupants 2, which are arranged along the directions of the frame beams 200 and the frame columns 300, respectively, in a three-dimensional cross pattern.

[0079] according to Figure 1 As shown, each upper protective layer occupant 1 includes a protective layer occupant unit 11 on the floor slab and an upper frame column protective layer occupant unit 12.

[0080] The protective layer occupant unit 11 on the floor slab is located directly above the frame beam 200 and is arranged along the central axis of the frame beam 200; the near end of the protective layer occupant unit 11 on the floor slab is attached to the side facade of the frame column 300.

[0081] according to Figure 8 As shown, the upper frame column protective layer occupant unit 12 is located on the side facade of the frame column 300. The outer facade of the upper frame column protective layer occupant unit 12 is flush with the side facade of the frame column 300 and is located near the end of the protective layer occupant unit 11 on the floor slab.

[0082] like Figure 2 As shown, the protective layer occupant unit 11 on the floor slab includes an intermediate protective layer occupant 111, a first side protective layer occupant 112, and a second side protective layer occupant 113.

[0083] The first side protective layer occupant 112 and the second side protective layer occupant 113 are mirror images of each other and are respectively located on both sides of the middle protective layer occupant 111.

[0084] The lower surface of the protective layer occupant unit 11 on the floor slab is uniformly provided with a first stirrup keyway 1111; the lower surface of the intermediate protective layer occupant 111 is also provided with a first damping occupant 1112; the outer facades of the first side protective layer occupant 112 and the second side protective layer occupant 113 are also provided with a second damping occupant 1121.

[0085] Specifically, the first stirrup keyway 1111 is designed to work with the stirrups on the steel reinforcement cage, and consists of multiple parallel, evenly distributed inner semi-cylindrical structures perpendicular to the central axis of the frame beam 200. The first stirrup keyway 1111 can engage with the stirrups during installation, ensuring a stable position between the protective layer occupant unit 11 on the floor slab and the steel reinforcement cage.

[0086] Preferably, the diameter of the inner semi-cylindrical portion of the first stirrup keyway 1111 is not less than the diameter of the stirrup rib. The first stirrup keyway 1111 is matched with stirrups that are evenly distributed and perpendicular to the tensile direction of the concrete floor slab 100.

[0087] In a further preferred embodiment, the first stirrup keyway 1111 has the same diameter as the stirrup rib.

[0088] After the concrete is poured, a raised stirrup key is formed on the upper bottom surface of the relief part 1001 of the concrete floor slab at the position corresponding to the first stirrup keyway 1111. The raised stirrup key not only increases the bonding force between the protective layer with damping structure and the concrete and steel bars, and significantly improves the internal force transmission between the protective layer with damping structure and the concrete floor slab 100, but also helps the protective layer occupant unit 11 on the floor slab to maintain the stability of its installation structure between the stirrup and the formwork during the concrete pouring process.

[0089] The first damping occupant 1112 is specifically a blind hole set between the first stirrup keyways 1111.

[0090] In a further preferred embodiment, the first damping occupant 1112 of this embodiment is a cone hole with a large opening, which facilitates the removal of the intermediate protective layer occupant 111.

[0091] In a further preferred embodiment, the blind hole depth of the first damping occupant 1112 in this embodiment is not less than half the height of the intermediate protective layer occupant 111; this design is beneficial for increasing the volume of the point key on the concrete floor slab, reducing the amount of ECC material used, and saving costs.

[0092] Preferably, multiple first damping occupants 1112 are arranged between adjacent first stirrup keyways 1111 and are evenly distributed.

[0093] In a further preferred embodiment, the multiple first damping occupants 1112 are arranged in a quincunx pattern.

[0094] After the concrete is poured, a key point is formed on the concrete floor slab at the position of a large number of first damping occupants 1112 distributed in a quincunx pattern on the upper bottom surface of the clearance part 1001. This can significantly improve the shear bond between the damping structure protective layer and the concrete, so that the two remain tightly bonded even after large deformation, and greatly improve the adhesion between the damping structure protective layer and the concrete.

[0095] according to Figure 3 and Figure 5 As shown, preferably, in this embodiment 1, upper occupant fixing platforms 1115 are respectively provided on both sides of the concrete floor slab intermediate protective layer occupant 111; the upper occupant fixing platforms 1115 are stepped platform structures, so that the cross-section of the concrete floor slab intermediate protective layer occupant 111 is a T-shaped structure.

[0096] The upper occupier fixing platform 1115 has first fixing mounting positions 1114 on both sides of the T-shaped horizontal plate, which are used to fasten / position the first side protective layer occupier 112 and the second side protective layer occupier 113 respectively.

[0097] In this embodiment 1, the first fixed mounting position 1114 is a through internal threaded hole / through hole.

[0098] according to Figure 5 As shown, preferably, the upper surface of the intermediate protective layer occupant 111 in this embodiment 1 is provided with a first disassembly and assembly tool mounting position 1113, so that the installation tool can be used to remove the intermediate protective layer occupant 111, or the intermediate protective layer occupant 111 can be connected to the mold plate using the first fastener.

[0099] Preferably, the first disassembly tool mounting position 1113 is a screw hole for connecting the first fastener, and the outer end face of the first fastener can be easily connected to the disassembly tool; the first disassembly tool mounting position 1113 can be used to install the disassembly tool after pouring concrete to facilitate the disassembly of the intermediate protective layer occupant 111; the first disassembly tool mounting position 1113 can also be used to fasten the intermediate protective layer occupant 111 to the mold plate before pouring concrete, thereby improving the positional stability between the protective layer occupant unit 11 and the mold plate on the floor slab during the pouring process, which is beneficial to improving the quality of concrete pouring.

[0100] according to Figure 4 As shown, the first side protective layer occupant 112 is a structural component whose thickness and connection structure match those of the middle protective layer occupant 111.

[0101] The first side protective layer occupant 112 is provided with a second damping occupant 1121, a side protective layer occupant fixing platform 1122 and a first locking position 1123.

[0102] according to Figure 5As shown, specifically, multiple second damping occupants 1121 are disposed on the outer facade of the first side protective layer occupant 112; the second damping occupant 1121 is specifically a blind hole structure, and the axis of the second damping occupant 1121 is parallel to the concrete floor slab 100.

[0103] Preferably, the blind hole structure of the second damping occupant 1121 in this embodiment 1 is an elongated oval blind hole; multiple second damping occupants 1121 are evenly distributed along the central axis of the frame beam 200, with the aim of maximizing the volume of the second damping occupants 1121 within a limited height.

[0104] After the concrete is poured, raised elongated concrete keys are formed on the side facade of the clearance portion 1001 of the concrete floor slab at positions corresponding to multiple second damping occupies 1121. Corresponding to the increased volume of the second damping occupies 1121, the elongated concrete keys formed after the concrete pouring are larger in volume, which helps to further reduce the amount of ECC material used later, thus lowering costs.

[0105] The elongated concrete key formed by the second damping occupant 1121 is located on the side elevation of the relief portion 1001 on the concrete floor slab. The side elevation of the protective layer relief portion 1001 on the floor slab is parallel to the tensile direction or has low stress. By setting an elongated protrusion on the side of the concrete, the bonding force between the part of the beam top surface with the damping structure protective layer and the frame slab concrete can be enhanced, and the gap between the two materials can be suppressed.

[0106] according to Figure 3 As shown, the depth of the second damping occupant 1121 cannot be greater than the distance L from the inner side of the occupant fixing platform 1115 on the middle protective layer occupant 111 to the outer side of the outermost first damping occupant 1112.

[0107] according to Figure 5 As shown, specifically, the side protective layer occupant fixing platform 1122 is a stepped platform structure that matches the upper occupant fixing platform 1115, and the side protective layer occupant fixing platform 1122 is provided with a first locking position 1123 that matches the first fixed installation position 1114.

[0108] Preferably, in this embodiment 1, the first locking position 1123 is a blind hole structure with internal threads. This allows the first side protective layer occupant 112 and the middle protective layer occupant 111 to be locked / positioned by a second fastener installed at the first locking position 1123 and the first fixed mounting position 1114. The second fastener is a double-ended bolt / single-ended bolt.

[0109] Preferably, in this embodiment 1, the second fastener is a stepped shaft component; the small diameter section of the second fastener is threaded to connect to the first locking position 1123; the large diameter section is cylindrical to transition to the first fixed mounting position 1114, and a tool interface is provided on the end face of the large diameter section to connect disassembly and fastening tools. This configuration can stabilize the protective layer occupant unit 11 on the floor slab and facilitate disassembly.

[0110] During the disassembly of the protective layer assembly spacer template with damping structure, the blind hole structure of the internal thread of the first locking position 1123 can also be used to install auxiliary disassembly tools in order to speed up the disassembly process.

[0111] Preferably, the first side protective layer occupant 112 in this embodiment 1 has an overall symmetrical structure; therefore, the first side protective layer occupant 112 and the second side protective layer occupant 113 in this embodiment 1 are structurally identical components.

[0112] according to Figure 2 As shown, the upper frame column protective layer occupant unit 12 includes an upper frame column first protective layer occupant 121 and an upper frame column second protective layer occupant 122 with the same length and thickness.

The two are structurally positioned correspondingly and together constitute the upper frame column protective layer occupant unit 12 of the square frame structure.

[0115] Specifically, the upper end face of the second protective layer occupant 122 of the upper frame column is attached to the lower end face of the first protective layer occupant 121 of the upper frame column and is flush with the upper surface of the intermediate protective layer occupant 111. The outer facade of the second protective layer occupant 122 of the upper frame column is attached to the front side facade of the intermediate protective layer occupant 111. This allows the concrete floor slab 100 to be used as a phased construction interface during the concrete pouring process, and the first protective layer occupant 121 of the upper frame column can be used in the construction process of the upper-level concrete frame structure.

[0116] according to Figure 6 As shown, the first protective layer occupant 121 of the upper frame column is a rectangular plate, on which a third damping occupant 1211, a second stirrup keyway 1212, a second fixed installation position 1213, and a second fixed locking position 1214 are provided.

[0121] Specifically, a second fixed mounting position 1213 is provided on the side facade at the second end of the first protective layer occupant unit of the upper frame column. The second fixed mounting position 1213 is specifically a through hole / screw hole, with the same height as the second fixed locking position 1214, and is located on the side of the first protective layer occupant body 121 of the upper frame column, specifically near the second end of the first protective layer occupant body 121. It is a through hole / through screw hole. An opening for a second stirrup keyway 1212 is provided on the first end of the first protective layer occupant body 121 of the upper frame column.

[0124] The third fastener can be used to fasten the first protective layer occupant 121 and the second protective layer occupant 122 of the upper frame column, which are connected end to end, to the corresponding concrete pouring mold plate.

[0125] The side length of the frame formed by the four upper frame columns and the first protective layer occupiers 121 is equal to the side length of the square frame column 300.

[0126] according to Figure 7 As shown, the upper frame column second protective layer occupant 122 is a rectangular plate with the same length as the first protective layer occupant 121, and a third fixed installation position 1221 and a third fixed locking position 1222 are provided on it.

[0127] Specifically, the third fixing and locking position 1222 on the second protective layer occupier 122 of the upper frame column is provided on the end face of its first side, preferably a threaded hole located in the middle.

[0128] Specifically, the third fixing mounting position 1221 on the second protective layer occupier 122 of the upper frame column is a through hole, located on the vertical surface at its second end, at a distance of 1 / 2 wall thickness from the second end, and at the same height as the second fixing locking position 1222. The side length of the frame formed by the four circumferentially connected and mutually perpendicular second protective layer occupiers 122 of the upper frame column is equal to the side length of the square frame column 300.

[0129] Preferably, the thickness of the second protective layer occupier 122 of the upper frame column is not less than the thickness of the concrete floor slab 100, which is H1.

[0130] The second protective layer occupant 122 of the upper frame column is the only occupant template component without damping decoupling strands, so that it can be easily removed after the subsequent concrete pouring.

[0131] like Figure 1 and Figure 9 As shown, the lower protective layer occupant 2 includes a floor slab lower protective layer occupant unit 21, a lower frame column protective layer occupant unit 22, and a frame beam vertical protective layer occupant body 23.

[0135] In this embodiment 1, each pair of vertical protective layer occupants 23 form a group, which are mirror images of each other.

[0136] according to Figure 9 and Figure 10 As shown, the set of floor slab lower protective layer occupant units 21 includes one first floor slab lower protective layer occupant 211 and one second floor slab lower protective layer occupant 212. The first floor slab lower protective layer occupant 211 and the second floor slab lower protective layer occupant 212 are arranged perpendicularly to each other in the lower surface of the concrete floor slab 100 and are respectively arranged along the central axis of two adjacent and mutually perpendicular frame beams 200.

[0137] according to Figure 10 As shown, the first lower protective layer occupant 211 of the floor slab is a cuboid plate, on which the lower protective layer damping occupant 2111, the lower protective layer stirrup keyway 2112, and the lower protective layer insertion position 2113 are provided.

[0138] The floor slab lower protective layer damping occupant 2111 is set on the upper end surface of the first floor slab lower protective layer occupant 211. The structure, arrangement and function of the floor slab lower protective layer damping occupant 2111 are the same as those of the first damping occupant 1112.

[0139] Multiple stirrup keyways 2112 under the floor slab protective layer are installed on the inner facade of the first lower protective layer occupier 211 of the floor slab, specifically as multiple parallel and evenly distributed inner semi-cylindrical structures perpendicular to the central axis of the frame beam 200. The structure, arrangement, and function of the stirrup keyways 2112 under the floor slab protective layer are the same as those of the first stirrup keyway 1111.

[0140] The floor slab insertion point 2113 is located on the inner side of the first lower protective layer occupant 211 of the floor slab and is used to position and connect the lower frame column protective layer occupant unit 22.

[0141] Preferably, in this embodiment 1, the floor slab insertion position 2113 is a rectangular recessed groove set on the edge, with a width and depth not exceeding 1 / 2 the wall thickness of the protective layer occupant 223 beside the lower frame column.

[0142] according to Figure 10 As shown, the second lower protective layer occupant 212 of the floor slab is a cuboid plate that is mirror-symmetrical to the structure of the first lower protective layer occupant 211 of the floor slab. The difference is that the near-end outer edge of the second lower protective layer occupant 212 of the floor slab has a floor slab clearance 2121.

[0143] Specifically, the clearance space 2121 under the floor slab is a cubic space with edges and thickness of equal length, which allows the first lower protective layer occupant 211 of the floor slab to be inserted into the cubic space of the clearance space 2121 under the floor slab to connect to the second lower protective layer occupant 212 of the floor slab. Together with the auxiliary lower protective layer stirrup keyway 2112, it is used to stabilize the positional relationship between the second lower protective layer occupant 212 of the floor slab and the steel reinforcement cage.

[0144] according to Figure 10 As shown, the vertical protective layer occupant 23 of the frame beam is a trapezoidal plate with one right-angled side. The upper end face of the right-angled trapezoidal side abuts against the outer side of the lower surface of the first lower protective layer occupant 211 of the floor slab. The near-end side facade of the right-angled trapezoidal side abuts against the outer facade of the lower frame column protective layer occupant unit 22 and is flush with the near-end side facade of the first lower protective layer occupant 211 of the floor slab.

[0145] The vertical protective layer occupant 23 of the frame beam is provided with a damping occupant 231 for the vertical protective layer of the frame beam and a stirrup keyway 232 for the vertical protective layer of the frame beam.

[0146] Specifically, the vertical protective layer damping occupant 231 of the frame beam is set on the inner facade of the vertical protective layer occupant 23 of the frame beam. The structure, arrangement and function of the vertical protective layer damping occupant 231 of the frame beam are the same as those of the first damping occupant 1112.

[0147] Specifically, the stirrup keyway 232 of the vertical protective layer of the frame beam is set on the inner side of the vertical protective layer occupier 23 of the frame beam. The structure, arrangement and function of the damping occupier 231 of the vertical protective layer of the frame beam are the same as those of the first stirrup keyway 1111, and the axial direction of the stirrup keyway 232 of the vertical protective layer of the frame beam is perpendicular to the central axis of the frame beam 200.

[0148] A frame beam vertical protective layer mounting position 233 can also be set on the frame beam vertical protective layer occupier 23; the frame beam vertical protective layer mounting position 233 is set on the outer facade of the frame beam vertical protective layer occupier 23 so as to be connected to the external mold plate through the fifth fastener, which facilitates the installation and removal of the frame beam vertical protective layer occupier 23.

[0149] Preferably, the fifth fastener is a stepped bolt, and the fifth fastener has an external thread structure at the part of the vertical protective layer occupier 23 connecting the frame beam.

[0150] according to Figure 9 and Figure 10 As shown, a set of lower frame column protective layer occupant units 22 includes one lower frame column first protective layer occupant 221, one lower frame column second protective layer occupant 222, and two lower frame column side protective layer occupants 223.

[0151] according to Figure 9 and Figure 10 As shown, the first protective layer occupant 221 and the second protective layer occupant 222 of the lower frame column are arranged end to end and perpendicular to each other. Two side protective layer occupants 223 of the lower frame column are respectively located on the outer vertical end faces of the first protective layer occupant 221 and the second protective layer occupant 222 of the lower frame column.

[0152] Specifically, a damping occupant 2211 and a stirrup keyway 2212 for the first protective layer of the lower frame column are provided on the inner facade of the first protective layer occupant 221 of the lower frame column; correspondingly, a damping occupant 2221 and a stirrup keyway 2222 for the second protective layer of the lower frame column are provided on the inner facade of the second protective layer occupant 222 of the lower frame column.

[0153] The damping occupants and stirrup keyways installed on the first protective layer occupant 221 of the lower frame column have the same structure, arrangement and function as the damping occupants and stirrup keyways installed on the vertical protective layer occupant 23 of the frame beam. The only difference is that the number of damping occupants and the length of the stirrup keyways vary depending on the arrangement area.

[0154] The first protective layer occupant 221 of the lower frame column is the same width as the first lower protective layer occupant 211 of the floor slab; the second protective layer occupant 222 of the lower frame column is the same width at its near end as the second lower protective layer occupant 212 of the floor slab.

[0155] Preferably, at the center of the overlap between the first protective layer occupant 221 of the lower frame column and the first lower protective layer occupant 211 of the floor slab, a first insertion position 2213 of the lower frame column is provided through on the side elevation of the first protective layer occupant 221. The first insertion position 2213 of the lower frame is specifically a through hole / through screw hole.

[0156] Preferably, corresponding to the first insertion position 2213 of the lower frame, a lower frame column locking part 2223 is provided on the outer end face of the second protective layer occupant 222 of the lower frame column. The lower frame column locking part 2223 is specifically a blind hole-shaped screw hole.

[0157] According to Figure 9 In the installed state, the first protective layer occupant 221 of the lower frame column and the second protective layer occupant 222 of the lower frame column are positioned / fastened by the fourth fastener.

[0158] Preferably, the fourth fastener is a stepped shaft-shaped fastening bolt, and the small diameter part of the fourth fastener is a bolt, used to screw the locking part 2223 of the lower frame column.

[0159] A side protective layer occupant 223 is provided on the outer end facade of the first protective layer occupant 221 and the second protective layer occupant 222 of the lower frame column.

[0160] The bottom end of the protective layer occupant 223 beside the lower frame column is flush with the bottom ends of the first protective layer occupant 221 and the second protective layer occupant 222 of the lower frame column. The upper end of the protective layer occupant 223 is higher than the upper surfaces of the first protective layer occupant 221 and the second protective layer occupant 222 by a thickness, so that the inner facade of the protective layer occupant 223 and the upper surfaces of the first and second protective layer occupants 221 and the second protective layer occupant 222 of the lower frame column form a structure that limits the front ends of the first and second lower protective layer occupants 211 and the second lower protective layer occupant 212 of the floor slab. This arrangement ensures the overall structural stability of the lower protective layer occupant 2 in the installed state.

[0161] The inner side of the protective layer occupant 223 of the lower frame column is provided with a lower frame column side stirrup keyway 2231 that has the same structure, arrangement and function as the stirrup keyway 2212 of the first protective layer and the stirrup keyway 2222 of the lower frame column.

[0162] The occupant 223 of the protective layer beside the lower frame column extends above the upper surfaces of the first protective layer occupant 221 and the second protective layer occupant 222 of the lower frame column by one wall thickness. A lower frame column side insertion part 2232 is located at the center of the upper part of an adjacent facade where the keyway 2231 for the side stirrups of the lower frame column is set. The lower frame column side insertion part 2232 is a protruding rectangular block, and its arrangement and dimensions are designed to match the floor slab insertion position 2113.

[0163] Preferably, in this embodiment 1, the side insertion part 2232 of the lower frame column is transitionally connected to the lower insertion part 2113 of the floor slab. This arrangement is beneficial to the overall structural stability of the lower protective layer occupant 2 in the installation state, and will not create a strong connection relationship during disassembly.

[0164] Preferably, in this embodiment 1, the stirrup key dimensions on each component plane are consistent, the damping space dimensions on each component plane are consistent, and the damping space dimensions on each component side end face are consistent. This configuration facilitates manufacturing.

[0165] Example 2

[0166] A building frame structure with a damping protective layer.

[0167] like Figures 11-16 As shown in the figure, this embodiment 2 discloses a building frame structure with a damping structure protective layer.

[0168] A building frame structure with a damping structure protective layer: characterized in that it includes a reinforced concrete frame and a high-ductility material protective layer (400).

[0169] In Example 2, a protective layer clearance portion is provided on the reinforced concrete frame. The protective layer clearance portion is a flip-form structure of the protective layer combination spacer template with damping structure in Example 1; a high-ductility material protective layer 400 is provided on the protective layer clearance portion; a first damping key 31 and / or a second damping key 32 are provided on the protective layer clearance portion, and a groove-shaped damping key 33 is also provided on the protective layer clearance portion.

[0170] Specifically, in the concrete pouring process of the building frame structure of Embodiment 2, a formwork with a protective layer combination spacer template with a damping structure as described in Embodiment 1 was used to form upper protective layer spacers at stress discontinuities in the reinforced concrete frame structure. Subsequently, a damping protective layer was constructed on the upper protective layer spacers to form a high-ductility material protective layer 400. The high-ductility material protective layer 400 was adhered to the reinforced concrete frame structure on the upper protective layer spacers, forming the building frame structure with a damping protective layer as described in Embodiment 2 of this invention.

[0171] like Figure 12As shown, the building frame structure of this embodiment 2 includes a reinforced concrete frame and a high-ductility material protective layer 400.

[0172] like Figure 11 As shown, the overall reinforced concrete frame includes the internal structure of the building frame, the side structure of the building frame, and the corner structure of the building frame.

[0173] In terms of specific structure, the reinforced concrete frame includes a concrete floor slab 100 formed by pouring concrete with a steel reinforcement skeleton, a frame beam 200, and a frame column 300.

[0174] Specifically, the high-ductility material protective layer 400 includes an internal high-ductility material protective layer 4001 disposed on the internal structure of the building frame, a side high-ductility material protective layer 4002 disposed on the side structure of the building frame, and a corner high-ductility material protective layer 4003 disposed on the corner structure of the building frame. The side high-ductility material protective layer 4002 and the corner high-ductility material protective layer 4003 are variations of the internal high-ductility material protective layer 4001.

[0175] This implementation scale 2 mainly introduces a partial building frame structure located inside the building body and with an internal high-ductility material protective layer 4001.

[0176] like Figure 13 and Figure 14 As shown, the reinforced concrete frame has a protective layer clearance section at the intersection of the concrete floor slab 100, the frame beam 200 and the frame column 300.

[0177] The process of forming the protective layer clearance section is as follows: During the concrete pouring process, the protective layer combination spacer template with damping structure of Example 1 is installed on the formwork plate. After the concrete is poured, the formwork plate and the protective layer combination spacer template with damping structure are removed to form the protective layer clearance section on the reinforced concrete frame.

[0178] In this embodiment 2, the high-ductility material protective layer 400 is applied to the protective layer relief area through a strict ECC construction process and then adhered to the reinforced concrete frame to form the building frame structure.

[0179] Specifically, the protective layer clearance portion includes a concrete floor slab clearance portion 1001 and a concrete floor slab lower clearance portion 1002 located on the concrete floor slab 100, a frame beam vertical clearance portion 2001 located on the side elevation of the frame beam 200, and an upper frame column protective layer clearance portion 3001 and a frame column lower clearance portion 3002 located on the frame column 300.

[0180] The upper frame column protective layer clearance portion 3001 is divided into upper and lower parts, including the upper frame column first clearance portion 30011 and the upper frame column second clearance portion 30012.

[0181] Because the concrete pouring construction is divided into sections with the upper surface of the concrete floor slab 100 as the boundary, during construction, the first clearance portion 30011 of the upper frame column is constructed along with the upper floor. The concrete pouring of this floor has the first clearance portion 30011 at the lower end of the frame column 300 and the second clearance portion 30012 at the upper end. The first clearance portion 30011 of the upper frame column at the lower end of the frame column 300 is located on the upper surface of the concrete floor slab 100 of the next floor.

[0182] The clearance portion 1001 on the concrete floor slab and the clearance portion 1002 under the concrete floor slab are obtained by setting up the protective layer occupant unit 11 on the floor slab and the protective layer occupant unit 21 under the floor slab.

[0183] Setting: In this embodiment 1, the stirrup keys on the plane of each component (which will form the same groove-shaped damping key 33 later) are of the same size, the damping occupants on the plane of each component (damping occupants with a cylindrical cross-section, which can form the same first damping point key 31 in the subsequent construction process) are of the same size, and the damping occupants on the side end face of each component (damping occupants with an oblong cross-section, which can form the same second damping point key 32 in the subsequent construction process) are of the same size.

[0184] like Figure 13 As shown, after pouring concrete, the first damping occupant 1112, the second damping occupant 1121, and the first stirrup keyway 1111 on the protective layer occupant unit 11 on the floor slab are generated on the vacant part 1001 of the concrete floor slab, and the first damping point key 31, the second damping point key 32, and the groove-shaped damping key 33 are generated on the vacant part 1001.

[0185] like Figure 14 As shown, the floor slab lower protective layer damping occupant 2111 and floor slab lower protective layer stirrup keyway 2112 on the floor slab lower protective layer occupant 211 and floor slab lower protective layer occupant 212 in the corresponding floor slab lower protective layer occupant unit 21, after the concrete is poured, the first damping point key 31 and the groove-shaped damping key 33 are generated on the concrete floor slab lower clearance part 1002.

[0186] like Figure 15 As shown, after the concrete is poured, the first damping key 31 and the groove-shaped damping key 33 are generated on the vertical protective layer occupant of the frame beam vertical protective layer and the stirrup keyway 232 of the frame beam vertical protective layer occupant.

[0187] like Figure 16 As shown, the third damping occupant 1211 and the second stirrup keyway 1212 on the frame formed by the first protective layer occupants 121 of the four upper frame columns are generated on the first clearance part 30011 of the upper frame column after the concrete is poured. The first damping point key 31 and the groove-shaped damping key 33 are generated on the first clearance part 30011 of the upper frame column.

[0188] like Figure 16 As shown, the second clearance part 30012 of the upper frame column is generated after the concrete is poured around the frame formed by the four upper frame columns and the second protective layer occupants 122.

[0189] like Figure 16 As shown, the first clearance portion 30011 of the upper frame column and the second protective layer occupant 122 of the upper frame column together constitute the upper frame column protective layer clearance portion 3001. The upper frame column protective layer clearance portion 3001 is provided with a first damping key 31 and a grooved damping key 33; wherein the grooved damping keys 33 on the first clearance portion 30011 and the second protective layer occupant 122 of the upper frame column have different sizes.

[0190] Figure 13 and Figure 14 This diagram illustrates a reinforced concrete frame structure with various protective layer clearances at the intersection of a central concrete slab 100, frame beams 200, and frame columns 300. An internal high-ductility material protective layer 4001 is formed by applying an ECC coating to each protective layer clearance, resulting in the desired structure. Figure 12 The partial building frame structure at that location.

[0191] like Figure 11 As shown, while constructing the various protective layer clearance parts and the internal high-ductility material protective layer 4001 inside the building, the construction of the various protective layer clearance parts of the middle structure and the side structure of the building frame structure, as well as the construction of the side high-ductility material protective layer 4002 and the corner high-ductility material protective layer 4003, can obtain the building frame structure with damping structure protective layer of this embodiment 2.

[0192] In this embodiment 2, the building frame structure with a damping structure protective layer significantly improves the adhesion between the ECC material and ordinary concrete in different directions through the first damping key 31 and the second damping key 32. It can generate stress transmission damping in the stress concentration part of the concrete frame structure, reduce the generation of cracks and brittle transmission in the stress concentration part of the concrete frame structure, restrict the deformation of the concrete frame, and significantly improve the service life of the building.

[0193] In this embodiment 2, the building frame structure with a damping structure protective layer uses grooved damping keys 33 to further bond the ECC material with the steel reinforcement skeleton, which greatly improves the three-body bonding strength of the damping structure protective layer, ordinary concrete and steel reinforcement skeleton. This allows the steel reinforcement structure to be better integrated with the ordinary concrete structure, further reducing the generation of cracks and brittle transmission at stress concentration points in the concrete frame structure, restricting the deformation of the concrete frame, and significantly improving the service life of the building.

[0194] In the building frame structure with damping structure protective layer in this embodiment 2, the first damping key 31, the second damping key 32 and the groove-shaped damping key 33 significantly reduce the effective volume of the clearance part of each protective layer, which significantly reduces the material consumption during ECC construction and lowers the construction material cost.

[0195] The protective layer combination occupant template with damping structure in this embodiment 2 forms a modular structure that not only facilitates individual production and easy assembly and disassembly, but also benefits from automated industrial production, which can improve production efficiency and reduce production costs. At the same time, the protective layer combination occupant template with damping structure can be reused in different construction projects, which is conducive to improving construction efficiency and reducing construction costs.

[0196] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
