It solves the problem in existing technologies where the tensile stress peak zone at the interface between high-ductility materials and ordinary concrete is discontinuous, leading to fatigue cracks or brittle failure in the building. The preparatory work of this method includes fabricating components of the high-ductility composite formwork, fabricating concrete pouring molds, and fabricating mold panel assemblies. The concrete construction of this method includes the orderly installation of the mold panel assemblies and the upper protective layer occupants on the reinforcing steel frame, and the orderly removal of each mold panel and each high-ductility composite formwork component and its protective layer occupant component. The construction of the protective layer includes the laying of high-ductility material in the protective layer's occupant area with a damping structure. This invention significantly reduces the generation of cracks and brittle fracture transmission in concrete frames, lowers construction costs, and increases the service life of building frame structures.

Description

Technical Field

[0001] This invention relates to the field of building structure technology, and specifically to a construction method for a building frame structure with a damping protective layer. 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 technologies for concrete structures during the construction phase, especially for super-large span concrete frame structures.

[0005] In ultra-large span reinforced concrete frame structures, there is a prominent problem of localized stress concentration 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 will lead to fatigue cracks or brittle failure of the concrete frame structure, reducing the building's service life.

[0006] 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 skeleton, and to use high-ductility materials, such as engineered cementitious composites, in areas prone to stress peaks.

[0007] Increasing the braiding density of the steel reinforcement in the skeleton will obviously lead to increased time and material costs.

[0008] When high-ductility materials are bonded to ordinary concrete interfaces, both materials must share the burden of fatigue cracking or brittle failure, resulting in higher costs. However, the construction process for high-ductility materials differs significantly from that of ordinary concrete structures throughout the entire construction process. Engineering practice shows that using high-ductility materials to bond with ordinary concrete interfaces is difficult to meet the stress requirements of ultra-large span concrete frame structures in the peak stress zone, resulting in discontinuity between the high-ductility materials and ordinary concrete in the peak tensile stress zone. Furthermore, to ensure a good bond between the high-ductility materials and ordinary concrete, the workload for surface roughening of the ordinary concrete is substantial, and the results are difficult to control. Moreover, high-ductility materials themselves are expensive.

[0009] To fully leverage the superior properties of high-ductility materials while eliminating the discontinuity between high-ductility materials and ordinary concrete in the peak tensile stress region, and to reduce the cost of high-ductility materials and construction, those skilled in the art must fully consider improvements to the bonding structure and construction methods between high-ductility materials and ordinary concrete. Summary of the Invention

[0010] Based on the above analysis, the present invention aims to provide a construction method for a building frame structure with a damping structure protective layer, in order to solve the problem in the prior art that the high ductility material protective layer and the connected ordinary concrete are discontinuous in the tensile stress peak area, resulting in poor crack resistance and affecting the service life of the building.

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.

[0064] This embodiment is configured as follows:

[0065] 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.

[0066] 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.

[0067] 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.

The damping occupants on the plane of all components are the same first damping occupant 01, the damping occupants on the side elevation of all components are the same second damping occupant 02, and the stirrup keyway occupants on the plane of all components are the same stirrup keyway occupants 03; the arrangement and size of multiple first damping occupants 01 and second damping occupants 02 are consistent; the subsequent construction process can form first damping key 31 and second damping key 32 with consistent size, as well as groove-type damping keys 33 with the same diameter (different lengths).

[0070] like Figure 3 As shown, the construction process inside the building frame structure in this embodiment involves a protective layer combination formwork with a damping structure. In this embodiment, the protective layer combination formwork with a damping structure is attached to the inner wall of a formwork box used for pouring concrete, and then the formwork box is installed onto the reinforcing steel skeleton; by pouring concrete into the formwork box, a reinforced concrete frame with concrete clearance sections at the intersection of the concrete floor slab 100, frame beam 200, and frame column 300 can be formed inside the building frame structure; then, high-ductility material is constructed at the concrete clearance sections to form a building frame structure with a high-ductility material protective layer 500.

[0071] This embodiment discloses a construction method for a building frame structure with a damping protective layer; specifically, it discloses a construction method for the interior of the building frame structure.

[0072] like Figure 2 As shown, this method is applicable to the entire building frame structure usage process, including the construction of the building frame side structure and the building frame corner structure.

[0073] like Figure 1 As shown, the specific steps of the construction method for a building frame structure with a damping protective layer in this embodiment are as follows:

[0074] S1. Preparations:

[0075] S11. Create a highly ductile combination placeholder template:

[0076] According to the following structural design, fabricate the various components included in the high-ductility composite spacer template:

[0077] like Figure 5 As shown, the high-ductility combined placeholder template involved in the method of this embodiment includes an upper protective layer placeholder 1 and a lower protective layer placeholder 2.

[0079] Specifically, each upper protective layer occupant 1 includes a protective layer occupant unit 11 on the floor slab and a protective layer occupant unit 12 for the upper frame column.

[0080] S1111, Fabricate the components for the protective layer occupant unit 11 on the floor slab:

[0081] like Figure 5 and Figure 6 As shown, the protective layer occupant unit 11 on the floor slab includes a middle protective layer occupant 111 of a long plate, a first side protective layer occupant 112, and a second side protective layer occupant 113. 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.

[0082] S11111, Fabricate intermediate protective layer spacer 111:

[0084] Specifically, the stirrup keyway occupants 03 on the protective layer occupant unit 11 on the floor slab are designed in conjunction with the stirrups on the steel reinforcement cage, specifically as multiple parallel and evenly distributed inner semi-cylindrical structures perpendicular to the central axis of the frame beam 200. The stirrup keyway occupants 03 can be fastened to the stirrups during installation, ensuring a stable position between the protective layer occupant unit 11 on the floor slab and the steel reinforcement cage.

[0085] Preferably, the diameter of the inner semi-cylindrical portion of the stirrup keyway occupier 03 is not less than the diameter of the stirrup rib. The stirrup keyway occupier 03 is matched with uniformly distributed stirrups, with its direction perpendicular to the tensile direction of the concrete floor slab 100.

[0088] Preferably, the depth of the blind hole in the first damping occupant 01 is not less than half the height of the plate it is located in. This design helps to increase the volume of the keyway on the concrete floor slab, reduces the amount of high-ductility material used, and saves costs.

[0089] Preferably, the multiple first damping occupants 01 on the intermediate protective layer occupant 111 are arranged between the adjacent stirrup keyway occupants 03 and are evenly distributed.

[0090] In a further preferred embodiment, the multiple first damping occupants 01 are arranged in a quincunx pattern.

[0091] S11112, Fabricate the first side protective layer occupant 112 and the second side protective layer occupant 113:

[0092] Since the first side protective layer occupant 112 and the second side protective layer occupant 113 are mirror images of each other, the structural technical solution of the first side protective layer occupant 112 will be introduced here.

[0093] 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.

[0103] Preferably, the second fixed mounting position 1211 is a through hole, and the second fixed locking position 1212 is a screw hole.

[0104] Specifically, in this embodiment, the stirrup keyway occupier 03 on the frame column bottom occupier 121 is set on its inner side facade, centered in the height direction.

[0116] The first occupant 211 and the second occupant 212 under the floor slab are inserted together. The two are rectangular plates with mirror-symmetric structure. The only difference is that a square notch with a side length equal to the thickness is provided at one corner of the second occupant 212 under the floor slab to accommodate the occupant.

[0117] Only the structure of the first occupant 211 under the floor slab is described.

[0118] The first occupant 211 under the floor slab is uniformly provided with a first damping occupant 01 on its upper plane and a stirrup keyway occupant 03 on the near-end side facade. The stirrup keyway occupant 03 is perpendicular to the central axis of the frame beam 200.

[0150] Preferably, the frame beam formwork side plate mounting position 4211 is designed to match the frame beam mounting position 231, and is a through hole structure. The height of the frame beam formwork side plate mounting position 4211 from the upper edge of the frame beam formwork side plate 421 is lower than the height of the frame beam mounting position 231 from the upper edge of the frame beam vertical protective layer occupier 23. The coverage difference is equal to the wall thickness of the formwork plate 41 under the floor slab.

The distance from the adjacent side is its own wall thickness plus 1 / 2 of the wall thickness of the first occupant 221 of the lower frame column. The height of the lower mounting position 433 on the frame column formwork plate from the lower edge matches the height design of the second fixed mounting position 1211.

[0156] Preferably, the mounting position 432 on the frame column mold plate and the mounting position 433 on the lower part of the frame column mold plate are through holes.

The height at this point is equal to the thickness of the lower formwork plate 41 of the floor slab.

[0167] The frame beam mounting position 231 on the vertical protective layer occupier 23 is aligned with the frame beam mold box side plate mounting position 4211 of the frame beam mold box unit 42. Two vertical protective layer occupiers 23 are then fastened to the slot structure of the frame beam mold box unit 42 using second fastening bolts. At this point, a frame beam mold box unit assembly is formed; four frame beam mold box unit assemblies form a set, ready for use.

[0168] The second fastening bolt is a stepped bolt with threads on the end, and the length of its threaded section matches the length of the optical axis section and the thickness of the frame beam mounting position 231 and the side plate 421 of the frame beam mold box.

[0172] The preferred third fastening bolt is a stepped bolt with a bolt at the end and two optical shafts on it. The length of each section is designed to match the length of the lower frame column locking part 2211, the lower frame column positioning part 2211 and the mounting position 432 on the frame column mold plate.

[0173] At the lower end of the frame column formwork plate 43, align the lower mounting position 433 of the frame column formwork plate 43 with the second fixed mounting position (1211) of the frame column bottom occupant 121, and pre-connect the three components with another third fastening bolt. At this point, the frame column formwork assembly is formed.

[0187] S222. Install the frame beam formwork unit assembly onto the steel reinforcement cage;

[0188] Take 4 sets of frame beam mold unit components, each with a total of 8 second fastening bolts.

[0189] like Figure 9 and Figure 4 As shown, the frame beam formwork base plate 422 of each set of frame beam formwork unit components is erected on the scaffold. The position of the frame beam formwork unit components is adjusted in the direction of the frame beam axis and gradually pushed up until the stirrup keyway occupant 03 on the frame beam vertical protective layer occupant 23 installed on the frame beam formwork unit component is hooked onto the stirrup of the steel reinforcement skeleton that will support the frame beam 200 in the future.

[0190] At this point, tightening the eight second fastening bolts allows the frame beam formwork unit assembly to be pre-positioned through the stirrup keyway positioning, the second fastening bolt tightening force, and the scaffolding support force. Once the frame beam formwork unit assembly is in place, it will further position and stabilize the floor slab formwork panel assembly on the steel reinforcement skeleton.

[0191] S223. Install the two frame column formwork assemblies and the two frame column formwork plates 43 onto the steel reinforcement cage:

[0192] Take 2 sets of frame column formwork components, 2 frame column formwork plates 43, and 4 third fastening bolts. There are a total of 8 third fastening bolts on them.

[0193] like Figure 9 and Figure 4 As shown, two sets of frame column formwork components are erected in relative positions on the next floor slab and attached to the steel reinforcement skeleton that will support the future frame columns 300. Then, two frame column formwork plates 43 are rotated 90° and connected end-to-end with the frame column formwork plates 43 in the two sets of frame column formwork components to form a frame that surrounds the steel reinforcement skeleton. At this time, the horizontal stirrup keyways 03 on the inner side of each of the four frame column formwork plates 43 are snapped onto the stirrups of the steel reinforcement skeleton.

[0194] The four separately placed third fastening bolts are placed in pairs in the two empty mounting positions of 432 and 433, and then locked together with the four third fastening bolts on the two sets of frame column mold box assemblies.

[0195] At this point, the formwork for the future concrete floor slab 100, frame beam 200, and frame column 300 is positioned and secured.

[0196] S224. Installation of the top occupant assembly for the reinforced concrete frame column:

[0197] Take four frame column top occupiers 122 and four fourth fasteners.

[0198] Four frame column top occupants 122 are connected end to end in pairs. At a set height, they are attached to the outside of the steel reinforcement skeleton that will support the frame column 300 on one side. The fourth fastener passes through the third fixed installation position 1221 of the previous frame column top occupant 122 and locks it onto the third fixed locking position 1222 of the next frame column top occupant 122. The four frame column top occupants 122 connected end to end in pairs are fastened to form a frame column top occupant assembly.

[0199] Preferably, the fourth fastener is a specially made stepped shaft with a threaded small diameter section and a smooth shaft at the large diameter end, which is fitted with a transition fit and has a height not greater than the thickness of the second protective layer occupier 122 of the frame column. The large diameter end face of the fourth fastener is provided with a positioning structure for disassembly and assembly tools.

[0200] The fourth fastener enhances the stable positioning of the frame column top occupant component without interfering with the installation of the protective layer occupant unit 11 on the floor slab.

[0201] The frame column top occupant component of the frame is located above the steel reinforcement skeleton of the future supporting frame beam 200 and surrounds the steel reinforcement skeleton of the future supporting frame column 300.

[0203] Take four intermediate protective layer occupants 111, four first side protective layer occupants 112, and four second side protective layer occupants 113; use one of each to construct a protective layer occupant unit 11 on the floor slab.

[0204] The first side protective layer occupant 112 and the second side protective layer occupant 113 are fastened together by conventional connection methods to form a protective layer occupant unit 11 on the floor slab; at this time, the second damping occupant 02 is located on the two side end faces of the protective layer occupant unit 11 on the floor slab, and the first damping occupant 01 and the stirrup keyway occupant 03 are located on the same plane of the protective layer occupant unit 11 on the floor slab.

[0205] The protective layer occupant unit 11 on the floor slab, with the first damping occupant 01 facing downwards, is arranged horizontally along the steel reinforcement skeleton of the future supporting frame beam 200, and is centered above the steel reinforcement skeleton. The near end of the protective layer occupant unit 11 on the slab abuts against the top occupant component of the frame column, and the two are aligned in the center.

[0206] At this time, the stirrup keyway 03 on the protective layer occupant unit 11 on the floor slab snaps onto the stirrup of the steel reinforcement cage, thus positioning the protective layer occupant unit 11 on the floor slab.

[0207] The upper surface of the protective layer occupant unit 11 on the floor slab is flush with the upper plane of the frame column top occupant component, and the upper planes of both are located on the upper plane of the future concrete floor slab 100.

[0208] S23. Pour concrete into the mold box and above:

[0209] Concrete is poured into the volume below the plane of the upper surface of the protective layer occupant unit 11 on the floor slab and above the formwork using conventional concrete pouring techniques.

[0215] like Figure 12 and Figure 13 As shown, four upper frame column second clearance portions 30012 are exposed on the reinforced concrete frame surrounding the lower end of the frame column 300; the upper frame column second clearance portions 30012 have their clearance portion damping structures, including their first damping point key 31 and their groove-shaped damping key 33.

[0216] Its groove-shaped damping key 33 is a 1 / 4 cylinder located at the lower edge; preferably, the diameter of the cylinder is equal to that of the stirrup.

[0217] S2422. Sequentially remove the four frame beam formwork unit components downwards, along with the vertical protective layer occupant 23 of the frame beam.

[0218] The frame beam formwork unit assembly can be dismantled as a whole, or the connection between the frame beam formwork side plate 421 and the frame beam formwork bottom plate 422 can be dismantled first; then the two frame beam formwork side plates 421 can be dismantled horizontally outwards, and then the frame beam formwork bottom plate 422 can be removed.

[0219] like Figure 13 As shown, the reinforced concrete frame exposes two vertical clearance portions 2001 on each frame beam 200, totaling eight locations; the vertical clearance portion 2001 contains a clearance portion damping structure, including its first damping point key 31 and its groove-shaped damping key 33.

[0222] like Figure 13 As shown, the reinforced concrete frame exposes one concrete floor slab clearance portion 1002 arranged at right angles in each area, for a total of four concrete floor slab clearance portions 1002. Each concrete floor slab clearance portion 1002 is equipped with a clearance portion damping structure, including a first damping key 31 and a groove-shaped damping key 33.

[0223] S2424, along the normal direction of its own plane, remove the first occupant 221 and the second occupant 222 of the lower frame column respectively.

[0224] S2425, Remove the 8 side occupants 223 of the lower frame columns:

[0225] S24251. Move the side occupant 223 of the lower frame column in the direction of the normal of the connection surface of the first occupant 221 / second occupant 222 of the lower frame column to a distance of 1 wall thickness; to facilitate the movement, screw holes can be pre-set on the side of the side occupant 223 of the lower frame column in the direction of movement, and a pulling tool can be installed.

[0226] S24252, Move the side occupant 223 of the lower frame column out along the normal direction of the first occupant 221 / second occupant 222 of the lower frame column to which it is connected.

[0227] like Figure 13 As shown, after steps S2424 and S2425, four upper frame column second clearance portions 3002, which are arranged at right angles at each edge of the upper part of the frame column 300, are exposed on the reinforced concrete frame; the upper frame column second clearance portions 3002 are provided with their clearance portion damping structures, including their first damping point key 31 and their groove-shaped damping key 33.

[0228] like Figure 14 As shown, the second clearance portion 3002 of the upper frame column is located away from the upper edge of the frame column 300, forming the inner groove 30021 of the lower clearance portion of the frame column; the positions of the inner grooves 30021 of the lower clearance portions of the eight frame columns correspond to the positions of the side occupants 223 of the eight lower frame columns.

[0229] S2426. Remove the protective layer occupying unit 11 on the floor slab:

[0230] First, remove the fasteners connecting the intermediate protective layer occupant 111 to the first side protective layer occupant 112 / second side protective layer occupant 113.

[0231] Next, remove the intermediate protective layer occupant 111 in an upward direction. To facilitate removal, screw holes can be pre-drilled on the intermediate protective layer occupant 111 for installing a pulling tool;

[0232] Then move the first side protective layer occupant 112 / the second side protective layer occupant 113 towards the location of the middle protective layer occupant 111 by a distance greater than the height of the second damping occupant 02.

[0233] Finally, remove the first side protective layer occupant 112 and the second side protective layer occupant 113 upwards.

[0234] Four clearance portions 1001 are exposed on the upper surface of the concrete floor slab 100 on the reinforced concrete frame; the clearance portions 1001 on the concrete floor slab are provided with their clearance damping structures, including their first damping key 31, their second damping key 32 and their groove-shaped damping key 33.

[0235] S2427. Remove the occupant components at the top of the frame column:

[0236] First, remove the fourth fastener.

[0237] Next, according to the normal direction of their respective planes, the occupants at the top of the frame columns 122 are removed one by one.

[0238] like Figure 15 As shown, four upper frame column first clearance portions 30011 are exposed on the reinforced concrete frame surrounding the upper end of the frame column 300; the upper frame column first clearance portions 30011 are provided with their clearance portion damping structures, including their first damping point keys 31.

[0239] The first clearance portion 30011 of the upper frame column sinks below the clearance portion 1001 on the adjacent concrete floor slab, forming the inner groove 300111 of the first clearance portion of the upper frame column.

[0240] The inner groove 300111 of the first clearance section of the upper frame column, the inner groove 30021 of the lower clearance section of the frame column, the first damping point key 31, the second damping point key 32 and the groove-shaped damping key 33 together form the clearance section damping structure on the reinforced concrete frame structure.

[0241] This completes the cement pouring of the reinforced concrete frame around one of the building's internal intersection points (the intersection of concrete floor slab 100, frame beam 200, and frame column 300). Following this procedure, the cement pouring of the reinforced concrete frames around other internal intersection points, as well as the intersection points of the side and corner structures, is completed on the same floor.

[0242] Repeat step S2 to complete the cement pouring of the reinforced concrete frame for the other floors of the entire building frame structure.

[0243] S3. Construction of high-ductility material protective layer:

[0244] In this embodiment, the high-ductility material selected is ECC material.

[0245] The ECC material protective layer is made using a conventional technical process, including: wetting the relief area with clean water / applying an interface agent to the relief area, spraying or troweling the ECC material layer onto the relief areas of each concrete frame, placing the ECC protective layer mold on the relief areas of the concrete frame with the ECC material layer before the concrete sets, removing the ECC protective layer mold from each protective layer component after the ECC material layer has set, and flushing the ECC protective layer with the outer surface of the concrete frame.

[0246] Figure 3 A partial view of an intersection point showing a central high-ductility material protective layer 5001.

[0247] Figure 2 The building frame structure of this embodiment is shown, including several concrete floor slabs 100, frame beams 200 and frame columns 300, and a high-ductility material protective layer 500.

[0248] The high-ductility material protective layer 500 includes a central high-ductility material protective layer 5001, a side high-ductility material protective layer 5002, and a corner high-ductility material protective layer 5003.

[0249] Because of the presence of the damping structure in the relief section, the adhesion between the high ductility material protective layer 500 and the ordinary concrete and stirrups in the reinforced concrete frame structure is greatly improved. This can significantly reduce the discontinuity of the peak tensile stress area in the concrete frame structure of ultra-large span buildings, overcome the problem of fatigue cracks or brittle failure in ultra-large span building frame structures, and significantly improve the service life of buildings.

[0250] The yielding damping structure reduces the volume of the yielding section in the reinforced concrete frame structure, which can effectively reduce the amount of high ductility materials used and reduce the construction cost of the main frame structure.

[0251] The construction method of building frame structure with damping structure protective layer of the present invention can ensure that the high ductility combined stationary template is easy to disassemble and assemble, can be reused in different building projects, and helps to reduce building construction costs.

[0252] The construction method for building frame structures with damping structure protective layer of the present invention can complete the assembly of high ductility combined occupant template components and concrete pouring mold plates in the assembly workshop, which makes mechanized operation possible, and can be expected to improve the quality and efficiency of building construction and save manpower.

[0253] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto.
