Description

Technical Field

[0001] The invention relates to the field of building construction structures, and in particular to a self-balancing connection structure and a connection method for an ultra-high Y-shaped rigid column. Background Art

[0002] During the construction of the oblique column part of the Y-shaped column, a large lateral force will be applied to the supporting frame, and there are no beams and slabs around it, so wall connecting parts cannot be installed and the whole frame is prone to overturning. In addition, an overweight beam is designed between the two oblique columns directly above the Y-shaped column. The traditional aluminum formwork and wooden formwork are unable to withstand the lateral pressure of concrete pouring on the oblique column (V-shaped) part of the Y-shaped column due to insufficient material strength and overall rigidity. In addition, manual formwork is prone to quality problems such as misalignment and leakage. Therefore, the traditional frame erection method cannot complete the beam formwork.

[0003] Due to the lack of similar cases for reference, the feasibility of the scheme cannot be guaranteed during the design process, and problems cannot be discovered in time and adjusted in a timely and dynamic manner. When the formwork is being dismantled, the tower crane and the truck crane cannot perform normal lifting work due to the obstruction of the upper beam plate. In addition, due to the tight joints of the steel formwork, mechanical tools (jacks) are required for dismantling. The traditional "install later and dismantle first" dismantling method is very dangerous and difficult to construct due to the high height and the obstruction of the frame to lift. Summary of the invention

[0004] Based on this, it is necessary to provide a self-balancing connection structure and connection method for an ultra-high Y-shaped rigid column to address the above-mentioned technical problems, which can effectively solve the problem that the tower crane's lifting weight cannot meet the one-time lifting needs. Since the Y-shaped column is relatively high, the concrete can be poured in sections to facilitate timely vibration during the pouring process, eliminating the trouble of opening vibration holes in each section of the steel formwork, and avoiding the risk of incomplete vibration due to excessively dense steel bars, which ultimately leads to quality defects.

[0005] The present invention provides a self-balancing connection structure of an ultra-high Y-shaped rigid column, comprising a vertical bottom column, a first inclined column, two multi-section inclined columns, two second inclined columns, and two vertical top columns; the first inclined column is arranged in a V-shaped structure, the first inclined column is arranged at the top of the vertical bottom column, the bottom ends of the two multi-section inclined columns are respectively located at the two ends of the top of the first inclined column, the two second inclined columns are respectively arranged on the two multi-section inclined columns, the two vertical top columns are arranged in parallel, and are respectively located on the two second inclined columns, the surfaces of the vertical bottom column, the first inclined column, the multi-section inclined column, the second inclined column and the vertical bottom column are all provided with at least four-sided steel molds, and the adjacent steel molds on the same structure are detachably connected.

[0006] In one embodiment, the vertical bottom column is vertically penetrated through the first beam, the second beam and the third beam, the first beam and the third beam respectively constitute the bottom plate and the top plate of the underground passage, and the vertical top column is penetrated through the fourth beam and the fifth beam, the fourth beam and the fifth beam respectively constitute the bottom plate and the top plate of the erected passage.

[0007] In one embodiment, the steel molds arranged on opposite sides of the two multi-section inclined columns are connected by a plurality of first tie rods, and the steel molds arranged on opposite sides of the two multi-section inclined columns are connected by a plurality of second tie rods crossing the multi-section inclined columns.

[0008] In one embodiment, the steel mold set on the surface of the first inclined column includes two first side panels, two second side panels and a curved panel; the two first side panels are located at the front and back of the first inclined column, the two second side panels are located at the two side surfaces of the first inclined column, and the curved panel is located at the top of the first inclined column, and a plurality of channel steels arranged in pairs are fixed on the first side panel, the second side panel and the curved panel, and the openings of the two channel steels arranged in pairs face opposite directions, and the adjacent ends of the channel steels on two adjacent plates are fixedly connected by an inclined third pull rod.

[0009] In one embodiment, an angle steel is fixed to the side of the channel steel end away from the plate, the angle formed by the angle steel faces the channel steel, the end of the third tie rod vertically passes through the surface of the angle steel, and a tightening piece is installed at the end of the third tie rod.

[0010] In one embodiment, the end of the second tie rod passes through the gap between the two channel steels arranged in a pair and is installed with a tightening piece.

[0011] In one embodiment, a first connecting head is fixed on the surface of the plate, and two opposite first connecting heads are connected by the first pull rod.

[0012] In one embodiment, a second connecting head is also fixed on the surface of the plate, one side of the second connecting head is connected to the plate, the other side of the second connecting head protrudes and is clamped in the opening of the channel steel, and the two opposite second connecting heads are also connected by the first pull rod.

[0013] In one embodiment, the first pull rod includes a rotating tube, two third connecting heads and two screws; one end of the two screws are threadedly installed on both ends of the rotating tube, and the other ends of the two screws are respectively connected to the two third connecting heads, and the third connecting heads are used to be interconnected with the second connecting head or the first connecting head.

[0014] The present invention also provides a method for connecting an ultra-high Y-shaped rigid column, which is applied to the self-balancing connection structure of the ultra-high Y-shaped rigid column described in any one of the above embodiments, and the method comprises:

[0015] The built-in structure of the vertical bottom column is erected, and the plate on the surface of the vertical bottom column is constructed, and then concrete is poured, and the vertical bottom column is formed after the concrete solidifies;

[0016] The built-in structure is erected and the surface panels are constructed in the order of the first inclined column, the multi-section inclined column, the second inclined column and the vertical top column, and concrete is poured immediately after each erection and construction is completed. After the concrete pouring is completed, the next column built-in structure is erected and the surface panels are constructed;

[0017] After all the columns have been poured with concrete, the multiple panels on the surface of the columns are removed one by one.

[0018] The self-balancing connection structure of the above-mentioned super-high Y-shaped rigid column and the connection method thereof are as follows: first, scaffolding is erected. Since the column is constructed from low to high, the scaffolding is erected synchronously according to the column erection height. When the vertical bottom column is constructed, the built-in structure of the vertical bottom column is first fixed at a specified position, and the steel formwork parts required for the surface of the vertical bottom column are assembled and fixed. After the fixing is completed, concrete is poured into the internal space of the plate. After the concrete solidifies, the built-in structure of the first inclined column above the vertical bottom column is erected, and then the steel formwork parts on the surface of the first inclined column are assembled and fixed. Subsequently, the pouring, solidification and erection process is repeated until the vertical top column located at the top is poured and solidified, and then the steel formwork parts on the surface of the column are removed one by one. During the removal process, the scaffold can also be gradually removed from top to bottom. The design and use of the above-mentioned customized steel formwork components solves the shortcomings of traditional wooden formwork and aluminum formwork due to insufficient material strength and overall rigidity, which cannot withstand the lateral pressure when pouring concrete on the oblique column of the Y-shaped column. It also avoids the problems of upper and lower layer misalignment and mortar leakage at the joints that may occur when manually assembling the formwork. Since the Y-shaped column adopts a segmented construction mode, that is, the frame is erected in segments, the built-in structure is hoisted in segments, and the steel formwork components are installed in segments, it effectively solves the problem that the tower crane cannot meet the one-time hoisting. And because the Y-shaped column is relatively high, by pouring the concrete in segments, it is convenient to vibrate it in time during the pouring process, eliminating the trouble of opening vibration holes in each section of the steel formwork, and avoiding the risk of imperfect vibration due to too dense steel bars, and ultimately quality defects. When dismantling the Y-column steel formwork, due to the limitations of the upper and lower beams, tower cranes and truck cranes cannot perform lifting operations smoothly. Therefore, a combined dismantling mode of truck crane, hoist and articulated arm truck can be used to solve the problem. This dismantling method adopts a bottom-up dismantling sequence, using the self-weight of the formwork to separate adjacent formworks, solving the problem of difficulty in dismantling due to the tight connection between adjacent steel formworks without gaps.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Combine the following Figures 1 to 8 The invention describes a self-balancing connection structure and a connection method of an ultra-high Y-shaped rigid column.

[0032] In one embodiment, a self-balancing connection structure of an ultra-high Y-shaped rigid column includes a vertical bottom column 100, a first inclined column 200, two multi-section inclined columns 300, two second inclined columns 400, and two vertical top columns 500; the first inclined column 200 is arranged in a V-shaped structure, the first inclined column 200 is arranged at the top of the vertical bottom column 100, the bottom ends of the two multi-section inclined columns 300 are respectively located at the two ends of the top of the first inclined column 200, the two second inclined columns 400 are respectively arranged on the two multi-section inclined columns 300, the two vertical top columns 500 are arranged in parallel, and are respectively located on the two second inclined columns 400, and the surfaces of the vertical bottom column 100, the first inclined column 200, the multi-section inclined column 300, the second inclined column 400 and the vertical bottom column 100 are all provided with at least four-sided steel molds, and adjacent steel molds on the same structure are detachably connected.

[0033] Specifically, the scaffolding is first erected. Since the column is constructed from low to high, the scaffolding is erected synchronously according to the column erection height. When constructing the vertical bottom column 100, the built-in structure of the vertical bottom column 100 is first fixed at the specified position, and the steel formwork parts required on the surface of the vertical bottom column 100 are assembled and fixed. After the fixing is completed, concrete is poured into the internal space of the plate. After the concrete solidifies, the built-in structure of the first inclined column 200 located above the vertical bottom column 100 is erected, and then the steel formwork parts on the surface of the first inclined column 200 are assembled and fixed. Subsequently, the pouring, solidification, and erection processes are repeated until the vertical top column 500 located at the top is poured and solidified, and then the steel formwork parts on the surface of the column are removed one by one. During the removal process, the scaffolding can also be gradually removed from top to bottom.

[0034] The self-balancing connection structure of the above-mentioned super-high Y-shaped rigid column first carries out scaffolding erection. Since the column is constructed from low to high, the scaffolding is erected synchronously according to the column erection height. When constructing the vertical bottom column 100, the built-in structure of the vertical bottom column 100 is first fixed at the specified position, and the steel formwork parts required on the surface of the vertical bottom column 100 are assembled and fixed. After the fixing is completed, concrete is poured into the internal space of the plate. After the concrete solidifies, the built-in structure of the first inclined column 200 located above the vertical bottom column 100 is erected, and then the steel formwork parts on the surface of the first inclined column 200 are assembled and fixed. Subsequently, the pouring, solidification, and erection processes are repeated until the vertical top column 500 located at the top is poured and solidified, and then the steel formwork parts on the surface of the column are removed one by one. During the removal process, the scaffold can also be gradually removed from top to bottom. The design and use of the above-mentioned customized steel formwork components solves the shortcomings of traditional wooden formwork and aluminum formwork due to insufficient material strength and overall rigidity, which cannot withstand the lateral pressure when pouring concrete on the oblique column of the Y-shaped column. It also avoids the problems of upper and lower layer misalignment and mortar leakage at the joints that may occur when manually assembling the formwork. Since the Y-shaped column adopts a segmented construction mode, that is, the frame is erected in segments, the built-in structure is hoisted in segments, and the steel formwork components are installed in segments, it effectively solves the problem that the tower crane cannot meet the one-time hoisting. And because the Y-shaped column is relatively high, by pouring the concrete in segments, it is convenient to vibrate it in time during the pouring process, eliminating the trouble of opening vibration holes in each section of the steel formwork, and avoiding the risk of imperfect vibration due to too dense steel bars, and ultimately quality defects. When dismantling the Y-column steel formwork, due to the limitations of the upper and lower beams, tower cranes and truck cranes cannot perform lifting operations smoothly. Therefore, a combined dismantling mode of truck crane, hoist and articulated arm truck can be used to solve the problem. This dismantling method adopts a bottom-up dismantling sequence, using the self-weight of the formwork to separate adjacent formworks, solving the problem of difficulty in dismantling due to the tight connection between adjacent steel formworks without gaps.

[0035] In one embodiment, the vertical bottom column 100 is vertically penetrated through the first beam 10, the second beam 20 and the third beam 30, and the first beam 10 and the third beam 30 respectively constitute the bottom plate and the top plate of the underground passage, and the vertical top column 500 is penetrated through the fourth beam 40 and the fifth beam 50, and the fourth beam 40 and the fifth beam 50 respectively constitute the bottom plate and the top plate of the erection passage.

[0036] Specifically, the first beam 10 and the third beam 30 are used to form the floor and ceiling of an underground passage or basement, the second beam 20 can be used as a layer of the basement, and the fourth beam 40 and the fifth beam 50 form the bottom and top surfaces of the suspended passage for pedestrians or vehicles.

[0037] In one embodiment, the steel molds arranged on opposite sides of two multi-section inclined columns 300 are connected by multiple first tie rods 800, and the steel molds arranged on opposite sides of the two multi-section inclined columns 300 are connected by multiple second tie rods 900 that cross the multi-section inclined columns 300.

[0038] Specifically, a tie rod, or a tie rod or a tie steel bar is arranged in the middle of the relative inclined column parts, which effectively avoids the risk of lateral tipping of the inclined column. After pulling, the main body of the inclined column part can be self-supporting, and the lateral pressure will not be transmitted to the surrounding frame, thus avoiding the safety hazard caused by the lateral force affecting the stability of the frame.

[0039] In one embodiment, the steel mold set on the surface of the first inclined column 200 includes two first side panels 210, two second side panels 230 and a curved panel 220; the two first side panels 210 are located on the front and back of the first inclined column 200, the two second side panels 230 are located on the two side surfaces of the first inclined column 200, and the curved panel 220 is located on the top of the first inclined column 200. A plurality of paired channel steels 610 are fixed on the first side panels 210, the second side panels 230 and the curved panel 220. The openings of the two paired channel steels 610 face opposite directions, and the adjacent ends of the channel steels 610 on two adjacent plates are fixedly connected by an inclined third pull rod 630.

[0040] Specifically, in this embodiment, the vertical bottom column 100, the first inclined column 200, the multi-section inclined column 300, the second inclined column 400 and the vertical top column 500 are all referred to as columns, and the steel formwork members arranged on the surface of the columns are all referred to as plates, wherein the first side plate 210, the second side plate 230 and the curved plate 220 are plates arranged on the surface of the first inclined column 200. According to actual building requirements, the number of sections of the multi-section inclined column 300 can be determined according to actual needs, and in this embodiment, there are four sections. Combined with the first inclined column 200 and the second inclined column 400, the Y-shaped column in this embodiment has a total of six sections except for the two vertical columns at the top and the bottom.

[0041] In one embodiment, an angle steel 620 is fixed to the end of the channel steel 610 away from the plate, and the angle formed by the angle steel 620 is opposite to the channel steel 610. The end of the third pull rod 630 vertically passes through the surface of the angle steel 620, and a tightening piece is installed at the end of the third pull rod 630.

[0042] Specifically, since the cross-section of the column is a rectangular structure, the multiple plates on the same column surface are in a vertical or parallel state at the horizontal section position. Therefore, when the angle steel 620 is set on the channel steel 610, the surfaces of the angle steel 620 on the two adjacent plates on the same column surface are parallel. The setting of the parallel surfaces makes it easier to position the third pull rod 630.

[0043] In one embodiment, the end of the second tie rod 900 passes through the gap between two channel steels 610 arranged in a pair and is installed with a tightening member.

[0044] Specifically, in order to facilitate the disassembly of the second pull rod 900, the end of the channel steel 610 can be set to protrude beyond the width of the column, so that the second pull rod 900 is located outside the column and is closer to the column. At this time, the second pull rod 900 can be clamped between two channel steels 610 arranged in pairs, which makes subsequent disassembly more convenient.

[0045] In one embodiment, a first connector 710 is fixed on the surface of the plate, and two opposite first connectors 710 are connected by a first tie rod 800. A second connector 720 is also fixed on the surface of the plate, one side of the second connector 720 is connected to the plate, and the other side of the second connector 720 protrudes and is clamped in the opening of the channel steel 610, and the two opposite second connectors 720 are also connected by the first tie rod 800. The first tie rod 800 includes a rotating tube 810, two third connectors 820 and two screws 830; one end of the two screws 830 is respectively threadedly installed on the two ends of the rotating tube 810, and the other ends of the two screws 830 are respectively connected to the two third connectors 820, and the third connector 820 is used to connect with the second connector 720 or the first connector 710.

[0046] Specifically, the connecting head is provided in a plate-like structure and is provided with a through hole. When the sides of the two connecting heads are fitted together, the two connecting heads can be fixedly connected by fasteners such as a pin shaft.

[0047] It should be noted that before construction, BIM calculation, analysis and simulation of Y-type columns are required. By connecting the Y-type columns with the surrounding super-high cantilever beams and designing and calculating them uniformly, it is ensured that the frame strength, overall rigidity and stability meet the construction requirements. Since the scaffolding frame outside the beam frame cannot be equipped with wall connecting parts, the super-high beam frame is connected with the already cast Y-type columns by holding the columns, which can solve the problem of insufficient stability caused by the super-high frame. For the KL17 (3B) support system, the method of increasing the frame column spacing is adopted to solve the problem that the formwork cannot be supported due to the limitation of the Y-type column. At the same time, measures such as increasing the number of columns and replacing square steel back ribs with channel steel 610 are taken to strengthen the frame stability caused by the increase in the column spacing and the excessive back rib deflection. By using BIM to deepen the design and construction process simulation, combined with finite element force analysis, the steel formwork and support frame construction process are adjusted in a timely and dynamic manner during the scheme design stage to ensure construction safety, construction efficiency and construction quality.

[0048] In one embodiment, a method for connecting an ultra-high Y-shaped rigid column is applied to a self-balancing connection structure of an ultra-high Y-shaped rigid column in any of the above embodiments, comprising the following steps:

[0049] The internal structure of the vertical base column 100 is erected, and the plate on the surface of the vertical base column 100 is constructed, and then concrete is poured, and the vertical base column 100 is formed after the concrete solidifies.

[0050] The built-in structure is erected and the surface panels are constructed in the order of the first inclined column 200, the multi-section inclined column 300, the second inclined column 400 and the vertical top column 500, and concrete is poured immediately after each erection and construction is completed. After the concrete pouring is completed, the next column built-in structure is erected and the surface panels are constructed.

[0051] After all the columns have been poured with concrete, the multiple panels on the surface of the columns are removed one by one.

[0052] The connection method of the above-mentioned super-high Y-shaped rigid column is to first erect a scaffolding. Since the column is constructed from low to high, the scaffolding is erected synchronously according to the column erection height. When constructing the vertical bottom column 100, the built-in structure of the vertical bottom column 100 is first fixed at a specified position, and the steel formwork parts required on the surface of the vertical bottom column 100 are assembled and fixed. After the fixing is completed, concrete is poured into the internal space of the plate. After the concrete solidifies, the built-in structure of the first inclined column 200 located above the vertical bottom column 100 is erected, and then the steel formwork parts on the surface of the first inclined column 200 are assembled and fixed. The pouring, solidification, and erection process are then repeated until the vertical top column 500 located at the top is poured and solidified, and the steel formwork parts on the surface of the column are removed one by one. During the removal process, the scaffolding can also be gradually removed from top to bottom. The design and use of the above-mentioned customized steel formwork components solves the shortcomings of traditional wooden formwork and aluminum formwork due to insufficient material strength and overall rigidity, which cannot withstand the lateral pressure when pouring concrete on the oblique column of the Y-shaped column. It also avoids the problems of upper and lower layer misalignment and mortar leakage at the joints that may occur when manually assembling the formwork. Since the Y-shaped column adopts a segmented construction mode, that is, the frame is erected in segments, the built-in structure is hoisted in segments, and the steel formwork components are installed in segments, it effectively solves the problem that the tower crane cannot meet the one-time hoisting. And because the Y-shaped column is relatively high, by pouring the concrete in segments, it is convenient to vibrate it in time during the pouring process, eliminating the trouble of opening vibration holes in each section of the steel formwork, and avoiding the risk of imperfect vibration due to too dense steel bars, and ultimately quality defects. When dismantling the Y-column steel formwork, due to the limitations of the upper and lower beams, tower cranes and truck cranes cannot perform lifting operations smoothly. Therefore, a combined dismantling mode of truck crane, hoist and articulated arm truck can be used to solve the problem. This dismantling method adopts a bottom-up dismantling sequence, using the self-weight of the formwork to separate adjacent formworks, solving the problem of difficulty in dismantling due to the tight connection between adjacent steel formworks without gaps.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
