Description

Technical Field

[0001] The invention relates to the technical field of foundation pit construction, and in particular to an axial force supporting structure for an enclosure with inclined replacement braces. Background Art

[0002] During the construction of the foundation pit, in order to speed up the progress of the project development, the scheme of "first excavating a deeper pit and then constructing a shallower pit" is usually adopted for the excavation of the basement, or the dividable pit scheme is adopted when the excavation area of ​​the foundation pit is large. The construction site usually excavates the earthwork on the other side of the separation pile (hereinafter referred to as the B side) before the construction of the basement top plate is completed on one side (the side with a larger excavation depth or the side excavated first, hereinafter referred to as the A side). In the enclosure scheme, temporary inclined bracing is generally set on the A side to share the soil pressure and water pressure generated during the excavation of the B side. The inclined bracing can effectively transfer the stress in the foundation pit to the new support system. Reasonable inclined bracing design can make the force in the foundation pit more uniform, effectively control the deformation generated during the excavation of the foundation pit, reduce the impact of excessive local stress on the main structure, and help maintain the integrity and durability of the main structure. However, since the bearing capacity of the steel structure is limited, when the stress transmitted from the B side is large, the spacing of the inclined bracing is reasonably designed to ensure that the stress transmitted to the structural beam and slab is relatively uniform, and the span of the inclined bracing is small, generally about 4 to 5 meters. However, the span of the main structure beams and columns is usually relatively large (about 8 to 9 meters). Whether the diagonal brace is placed on the structural column with a larger span or on the structural beam, it will have an adverse effect on the main structure.

[0003] Therefore, this application designs a node structure in which temporary steel columns are set at the intersection of the main beam and the secondary beam. The axial force of the diagonal brace is transmitted to the main beam-slab structural system through the temporary steel columns and concrete piers, and the three are effectively connected. This is of great significance for guiding on-site construction. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0033] like Figures 1 to 13As shown, the present application proposes a supporting structure for the axial force of the enclosure oblique replacement support.

[0034] Example 1

[0035] It includes a structural base plate 81 and a structural beam 2, and is characterized in that it also includes a temporary steel column 3, a concrete pier 4, an oblique brace 5 and an embedded part 6; the upper end of the temporary steel column 3 is anchored with steel bars at the intersection of the structural beam 2, the lower end of the temporary steel column 3 is fixedly connected to the structural base plate 81, the lower end of the concrete pier 4 is anchored with steel bars at the upper end of the structural beam 2, and there are two groups of embedded parts 6, which are respectively arranged on the side of the concrete pier 4 and the side of the purlin 7, one end of the oblique brace 5 is connected to the purlin 7 through the embedded part 6, and the other end of the oblique brace 5 is connected to the concrete pier 4 through the embedded part 6; the soil and water pressure on the purlin 7 is transmitted to the inside of the concrete pier 4 through the oblique brace 5, and is further transmitted to the main structure force system through the temporary steel column 3.

[0036] It should be noted that a plurality of through holes are provided at the upper end of the temporary steel column 3 so that the longitudinal reinforcement of the structural beam 2 can pass through, and the diagonal brace 5 is welded and connected to the embedded part 6 .

[0037] The cross-sectional size of the temporary H-shaped steel column is preferably H300x300x13x21 steel, and it is set just below the intersection of the main and secondary beams of the structure; the temporary H-shaped steel column is anchored 300mm into the structural bottom plate 81, and the position of the temporary H-shaped steel column needs to be reserved according to the design requirements when the structural bottom plate 81 is cast; the temporary H-shaped steel column is anchored 500mm into the structural beam 2, and if the H-shaped steel anchored in the beam conflicts with the longitudinal reinforcement of the structural beam 2, the H-shaped steel is perforated;

[0038] The preferred cross-sectional dimensions of the concrete pier 4 are 600mm long*width with beam width*700mm high, the pier concrete strength grade is C35, and the longitudinal steel bars need to be anchored into the structural beam 2;

[0039] The diagonal brace 5 is preferably an H-shaped steel, with a preferred cross-sectional size of H400x400x13x21. One end of the steel is connected to the surrounding purlin, and the other end is connected to the concrete pier 4 through the embedded part 6. The embedded part 6 of the diagonal brace 5 is fully welded, and the weld height hf is preferably 10 mm.

[0040] The embedded part 6 preferably has a cross-sectional size of 500x500x15 and is centrally anchored in the concrete pier 4.

[0041] Working principle: Determine the length and position of temporary steel columns 3 and the length of diagonal braces 5 according to design requirements. In the specific implementation process, first reserve the position of temporary steel columns 3 when pouring the structural bottom plate 81. After the structural bottom plate 81 and the force transmission belt reach 80% of the design strength, gradually remove the second horizontal support, and construct temporary steel columns 3. The bottom of temporary steel columns 3 is anchored 300mm into the structural bottom plate 81, and the top is anchored 500mm into the structural beam 2. If the H-shaped steel anchored in the beam conflicts with the longitudinal reinforcement of the structural beam 2, the web of the H-shaped steel is perforated. When constructing the underground second-floor structure, the underground first-floor beam and brace, set up 3 temporary steel columns, and set up concrete piers 4 above the intersection of the structural beams 2 to provide a fulcrum for the diagonal braces 5. The concrete piers 4 can be cast integrally with the structural beams 2, and the longitudinal reinforcement of the concrete piers 4 needs to be anchored into the structural beams 2. After the construction of the concrete pier 4 is completed, the embedded part 6 is set at the center of the concrete pier 4, and then the steel diagonal brace 5 is erected. One end of the diagonal brace 5 is connected to the purlin 7, and the other end is connected to the concrete pier 4 through the embedded part 6. It is ensured that the central axis of the diagonal brace 5 and the embedded part 6 are on the same plane, and the diagonal brace 5 and the embedded part 6 are fully welded. After the steel diagonal brace 5 is set and the beam and slab of the underground layer reaches 80% of the design strength, the first horizontal support is gradually removed. After the construction of the basement structure is completed, the diagonal brace 5 and the temporary steel column 3 are removed (cut), and the concrete pier 4 is chiseled out.

[0042] Example 2

[0043] As another example, Figures 4 to 12 As shown, it also includes an auxiliary installer 8, which includes a base plate 81, a hydraulic lifter 82, an upper plate 83, a lifting mechanism 84 and a clamping mechanism 85; the lower end of the hydraulic lifter 82 is bolted to the base plate 81, the output end of the hydraulic lifter 82 is bolted to the upper plate 83, the lower end of the lifting mechanism 84 is bolted to the upper end of the upper plate 83, and the clamping mechanism 85 is rotatably connected to the upper end of the lifting mechanism 84.

[0044] After the installation of the temporary steel column 3 is completed, when the installation of the diagonal brace 5 is required, the auxiliary installer 8 can be used for auxiliary installation and removal. The diagonal brace 5 is locked and clamped by the provided clamping mechanism 85, and the lifting mechanism 84 is lifted and lowered differently on both sides to make the diagonal brace 5 tilt to the required tilt angle of the design. Then the auxiliary installer 8 is pushed to the installation position to align the two sides of the diagonal brace 5 with the embedded parts 6, and the diagonal brace 5 can be installed.

[0045] See also Figures 4 to 7As shown, the lifting mechanism 84 is provided with two groups, including a fixed seat 841, a diamond-shaped connecting rod 842, a mounting seat 843, a hinge pin 844, a driving rotating rod 845, a transmission assembly 846 and a rotating pin 847. The lower end of the fixed seat 841 is bolted to the upper end of the upper plate 83, the lower end of the diamond-shaped connecting rod 842 is rotatably connected to the fixed seat 841 with damping, the upper end of the diamond-shaped connecting rod 842 is fixedly connected to the rotating pin 847, the rotating pin 847 is rotatably connected to the mounting seat 843 with damping, the middle part of the diamond-shaped connecting rod 842 is rotatably connected through the hinge pin 844, the driving rotating rod 845 passes through the hinge pin 844 and is threadedly connected to the hinge pin 844, and one end of the driving connecting rod is welded to the transmission assembly 846.

[0046] Among them, corresponding hollow parts are set on the upper and lower sides of the diamond-shaped connecting rod 842, so that the upper diamond-shaped connecting rod 842 can be inserted into the lower diamond-shaped connecting rod 842 when the diamond-shaped connecting rod 842 is folded, so that the folding angle of the diamond-shaped connecting rod 842 is larger, and the rotating connection of the diamond-shaped connecting rod 842 is provided with a certain damping to prevent it from excessive rotation and enhance the stability of the device.

[0047] When the diagonal change brace 5 needs to be installed, the diagonal change brace 5 is placed on the clamping mechanism 85, which is locked and clamped by the clamping mechanism 85, and then the transmission component 846 is started. The transmission component 846 drives the two sets of driving rods 845 to rotate, thereby driving the hinge pins 844 threadedly connected thereto to shift horizontally, so that one set of diamond-shaped connecting rods 842 is unfolded and the other set of diamond-shaped connecting rods 842 is folded, thereby driving the mounting seat 843 on one side to rise and the mounting seat 843 on the other side to fall, so that the diagonal change brace 5 is tilted until it moves to the preset design angle and stops.

[0048] See also Figure 6 as well as Figure 7 The driving rotating rod 845 includes a driving rotating rod A8451 and a driving rotating rod B8452. Both ends of the driving rotating rod A8451 and the driving rotating rod B8452 are provided with threads in opposite directions. The driving rotating rod A8451 is threadedly connected to the hinge pin 844, and the driving rotating rod B8452 is threadedly connected to the hinge pin 844. The thread directions of the driving rotating rod A8451 and the driving rotating rod B8452 are opposite.

[0049] Since the thread directions at both ends of the driving rod 845 are opposite, when the driving rod 845 rotates, the hinge pins 844 at the two locations approach or move away from each other in the horizontal direction of the driving rod 845, thereby driving the diamond connecting rod 842 to unfold or fold. Since the thread directions of the driving rod A 8451 and the driving rod B 8452 are opposite, when the transmission assembly 846 drives the two groups of driving rods 845 to rotate in the same direction at the same time, the movement directions of the two groups of hinge pins 844 are opposite, forming an operating trajectory in which one group of diamond connecting rods 842 is folded and the other group of diamond connecting rods 842 is unfolded.

[0050] At the same time, the upper plate 83 can be driven to rise or fall by the provided hydraulic lifter 82, thereby causing the lifting mechanism 84 to undergo an overall vertical movement to change the overall installation height of the diagonal brace 5.

[0051] See also Figures 5 to 7 The transmission assembly 846 includes a motor 8461, a pulley 8462 and a synchronous belt 8463, and also includes two sets of telescopic rotating rods 8464, a connecting plate 8465, a bevel gear 8466 and a bevel gear 8467; the upper end of the motor 8461 is bolted to the lower end of the upper plate 83, the output end of the motor 8461 is plugged into a set of telescopic rotating rods 8464, the lower end of the other set of telescopic rotating rods 8464 is rotatably connected to the bottom wall of the upper plate 83, and the middle parts of the two sets of pulleys 8462 are respectively connected to the two sets of telescopic rotating rods. The rotating rod 8464 is fixedly connected, and the two sets of pulleys 8462 are connected through the synchronous belt 8463; the upper end of the telescopic rotating rod 8464 passes through the upper plate 83 and is connected to the connecting plate 8465 with a limited rotation, the lower end of the bevel gear 8467 is welded and fixed to the upper end of the telescopic rotating rod 8464, one end of the driving rotating rod 845 is connected to the connecting plate 8465 with a limited rotation, one end of the driving rotating rod 845 is welded and fixed to the bevel gear 8466, and the bevel gear 8467 is meshed with the bevel gear 8466.

[0052] Among them, motor 8461 is a bidirectional rotating motor 8461. When the diagonal support 5 is locked and fixed by the clamping mechanism 85, the motor 8461 is started, and the output end of the motor 8461 drives the telescopic rotating rod 8464 to rotate, and then drives the telescopic rotating rod 8464 on the other side to rotate synchronously in the same direction through the transmission of the pulley 8462 and the synchronous belt 8463, thereby driving the bevel gear 8467 to rotate. The rotation of the bevel gear 8467 drives the bevel gear 8466 meshing with it to rotate, and then drives the driving rotating rod 845 to rotate, so that the hinge pin 844 is relatively displaced. When the diamond connecting rod 842 is folded or unfolded, the driving rotating rod 845 will be displaced in the vertical direction, thereby driving the connecting plate 8465 to be displaced. The connecting plate 8465 drives the telescopic rotating rod 8464 with a limited rotation connection to it to contract or extend to adapt to the height of the driving rotating rod 845 to avoid drive loss.

[0053] Example 3

[0054] As another example, Figure 5 , Figure 8 as well as Fig. 9As shown, the clamping mechanism 85 includes a rotating shaft 851, a placement plate 852, a fixed plate 853, a positioning pin 854, a telescopic arm 855, a sliding block 856 and a clamping pin 857; the placement plate 852 is connected to the mounting seat 843 in a damped rotational connection via the rotating shaft 851, the positioning pin 854 is arranged on the upper surface of the placement plate 852, one end of the telescopic arm 855 is rotationally connected to both sides of the placement plate 852, the other end of the telescopic arm 855 is welded and fixed to the fixed plate 853, a through hole is provided on the fixed plate 853, the sliding block 856 is slidably connected to the fixed plate 853, the clamping pin 857 passes through the sliding block 856 and passes out through the through hole, the clamping pin 857 is rotationally connected to the sliding block 856, a thread is provided on the surface of the clamping pin 857, and the positioning pin 854 is provided with an internal thread matching the clamping pin 857.

[0055] The clamping mechanism 85 also includes a sliding block 856, which is slidably connected to the fixed plate 853. The clamping pin 857 passes through the sliding block 856 and comes out through the through hole. The clamping pin 857 is rotatably connected to the sliding block 856. The surface of the clamping pin 857 is provided with a thread, and the positioning pin 854 is provided with an internal thread matching the clamping pin 857.

[0056] A locking slide rail may be provided below the positioning pin 854 so that the positioning pin 854 can be adapted to the diagonal brace 5 of different widths. When installing the diagonal brace 5, firstly, the two groups of rhombus connecting rods 842 are parallel, the diagonal brace 5 is placed flat on the placement plate 852 and between the positioning pins 854, then the fixed plate 853 is pulled to move in a circle around the rotating shaft 851 to the upper end of the lower plate of the H-shaped steel, the clamping pin 857 is held, and the clamping pin 857 is inserted into the positioning pin 854 by sliding the sliding block 856, and the clamping pin 857 is rotated so that the clamping pin 857 moves downward along the positioning pin 854 by means of the threaded connection with the positioning pin 854, forcing the telescopic arm 855 to contract, so that the fixed plate 853 and the placement plate 852 clamp the diagonal brace 5 at the same time.

[0057] Among them, the surfaces of the fixing plate 853 and the placing plate 852 are provided with cushion layers or friction patterns for increasing friction force, so as to increase friction force and achieve a better clamping effect.

[0058] When the lifting mechanism 84 moves, the diagonal brace 5 is driven to tilt, and the placement plate 852 rotates in a corresponding manner using the damped rotation connection with the mounting seat 843 to maintain the clamping of the diagonal brace 5; when disassembling the diagonal brace 5, the clamping mechanism 85 is moved to the specified position by the lifting mechanism 84, and then the diagonal brace 5 is clamped and locked. After the disassembly of the nodes at both ends of the diagonal brace 5 is completed, the lifting mechanism 84 moves the diagonal brace 5 to the same level as the ground, and lowers it through the hydraulic lifter 82, and then it can be unlocked for transportation.

[0059] Working principle: During installation, place the diagonal brace 5 between the positioning pins 854 of the placement plate 852, then rotate the fixed plate 853, insert the clamping pin 857 into the positioning pin 854 and rotate it, so that the fixed plate 853 and the placement plate 852 clamp and lock the diagonal brace 5, then start the motor 8461, and drive the telescopic rotating rods 8464 on both sides to rotate through the motor 8461, drive the bevel gear 8467 to rotate and finally drive the driving rotating rod 845 to rotate, so that one group of diamond connecting rods 842 are folded and the other group of diamond connecting rods 842 are unfolded, driving the diagonal brace 5 to tilt, and aligning the two ends of the diagonal brace 5 with the embedded parts 6, and then the installation operation can be carried out. After the installation is completed, the clamping mechanism 85 is unlocked, and the motor 8461 is reversed to make the auxiliary installer 8 return to its initial state.

[0060] Example 4

[0061] As another embodiment, the connection form between the clamping pin 857 and the positioning pin 854 of this embodiment is different from that of the embodiment 3, such as Fig.10 As shown, the clamping mechanism 85 also includes a foldable telescopic rod 858, a clamping pin 857 fixedly connected to the fixed plate 853, the clamping pin 857 and the positioning pin 854 are in an unlockable snap-fit ​​form, both ends of the folding part of the foldable telescopic rod 858 are telescopic structures, the lower end of the foldable telescopic rod 858 is rotatably connected to the eccentric position of the rotating pin 847, and the upper end of the foldable telescopic rod 858 is rotatably connected to the connection between the telescopic arm 855 and the rotating shaft 851.

[0062] After the diagonal shift support 5 is placed between the positioning pins 854, the motor 8461 is started to drive the two sets of diamond-shaped connecting rods 842 to fold and unfold independently, so that the rotating pin 847 rotates, drives the folding telescopic rod 858 to move upward, drives the telescopic arm 855 to flip, and makes the fixed plate 853 automatically fold in the direction of the placement plate 852, so that the clamping pin 857 is inserted into the interior of the positioning pin 854 and locked, so as to clamp the diagonal shift support 5.

[0063] It should be noted that when the two sets of diamond-shaped connecting rods 842 are in a parallel state, the folding telescopic rod 858 is in a fully retracted shortest state so that an upward thrust can be generated. When the rotating pin 847 rotates it to the uppermost end, the clamping pin 857 completes the locking. Subsequently, the folding telescopic rod 858 moves downward and is automatically stretched to prevent jamming. During the tilting process of the diagonal support 5, the telescopic arm 855 moves in a synchronous circular motion, utilizing the foldability of the folding telescopic rod 858 and the telescopicity of the upper end to adapt to this circular motion.

[0064] Secondly, since the movement directions of the two groups of diamond-shaped connecting rods 842 are opposite, the eccentric positions of the folding and telescopic rods 858 in the same group and the rotating pin 847 are symmetrical, and the eccentric positions of the folding and telescopic rods 858 in different groups and the rotating pin 847 are opposite.

[0065] Example 5

[0066] As another embodiment, this embodiment provides a connection form between the oblique support 5 and the embedded part 6 which is different from that in Embodiment 1, such as Figures 11 to 13 As shown, it also includes a connector 9, which includes a trapezoidal tenon 91, a slot 92, a spring 93, a tilting locking block 94 and an unlocking telescopic rod 95. The trapezoidal tenon 91 is installed at both ends of the oblique support 5, the slot 92 is installed on the surface of the embedded part 6, the tilting locking block 94 is slidably connected to the inner wall of the slot 92, one end of the spring 93 is fixedly connected to the rear end of the tilting locking block 94, and the other end of the spring 93 is fixedly connected to the inner wall of the slot 92. The unlocking telescopic rod 95 includes an outer rod 951 and an inner rod 952, the inner rod 952 is sleeved in the outer rod 951 and slidably connected, the outer rod 951 is fixedly connected to the inner wall of the slot 92, the end of the inner rod 952 away from the outer rod 951 is fixedly connected to the tilting locking block 94, and the other end of the inner rod 952 extends outward through the side wall of the slot 92.

[0067] After the temporary steel column 3 and the concrete pier 4 are installed, the lifting mechanism 84 tilts the diagonal support 5 to a specified angle, and then the hydraulic lifter 82 is started to push the upper plate 83 up as a whole, thereby driving the diagonal support 5 to rise as a whole to the upper part of the slot 92, and the universal wheel 811 is used to drive the diagonal support 5 to move as a whole to the same vertical position as the slot 92. Then the hydraulic lifter 82 drives the upper plate 83 to descend, the diagonal support 5 descends as a whole, the trapezoidal tenon 91 is inserted into the slot 92, and the trapezoidal slope is used to squeeze the tilt locking block 94 to both sides. After the trapezoidal tenon 91 is fully inserted into the slot 92, the tilt locking block 94 loses its limit, and is acted upon by the spring 93 to approach each other above the trapezoidal tenon 91 to form a lock on the trapezoidal tenon 91. When unlocking is required, the inner rods 952 on both sides are pulled to cause the tilt locking block 94 to move in the opposite direction to unlock. Among them, since the horizontal distance between the surrounding purlin 7 and the concrete pier 4 is fixed, the length and angle of the diagonal brace 5 are manufactured and installed according to the design requirements, so there is no need to consider the locking in the horizontal direction.

[0068] The connection method provided in this embodiment is also applicable to the traditional lifting or other installation forms of the diagonal support 5. When the auxiliary installer 8 disclosed in the present invention is used, this connection method has the beneficial effects of greatly reducing manual participation, improving operation safety, and reducing labor intensity.

[0069] It should be noted that an array of lockable universal wheels 811 are provided at the lower end of the base plate 81, and a pushing handle 812 is installed on the side of the base plate 81 to facilitate the movement of the pushing device; the auxiliary installer 8 is also provided with a controller, and the controller is connected to the motor 8461 by electrical signals so that the motor 8461 automatically drives the lifting mechanism 84 according to the required tilt angle of the diagonal support 5.
