Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building assembly positioning, in particular to an assembly component hoisting positioning device and a use method thereof. BACKGROUND

[0002] In a building project, the hoisting and accurate positioning of an assembly component is a key process.

[0003] In the construction of an assembly pile, an upper section of a prefabricated pile body needs to be hoisted and accurately connected to a lower section of a pile body or a poured concrete bottom plate, to ensure that the plan position, elevation and perpendicularity meet the design requirements. In the prior art, the common positioning methods mainly rely on two ways: one is the traditional manual assisted positioning, that is, a construction worker performs real-time observation and commands a hoisting device to roughly position, and then uses a crowbar, a jack and other tools to manually fine-tune and correct; the other is to use a special rigid positioning frame or a guide mold, which is fixed on the lower foundation or reinforcement cage in advance to provide a physical guide channel for the falling of the upper section of the pile body.

[0004] Firstly, the traditional manual positioning method is low in efficiency and the accuracy is greatly affected by human factors, and there is a high safety risk in the fine-tuning stage after the rough positioning of the pile body. Secondly, the guide frame structure commonly used at present is usually independent of the final bearing support system, and the separation of the guide and support functions causes a series of problems: firstly, the independently arranged guide frame structure is usually thin, and when a large prefabricated component (such as a pile) in the initial hoisting stage contacts or collides with the guide frame, the guide frame is easily deformed or damaged due to the lack of effective internal support, and loses the guiding function; secondly, after the preliminary positioning of the component, an additional and independent support leveling system (such as a cushion block, a jack, etc.) is still needed for the final accurate positioning and stable support, and the process is complicated. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides an assembly component hoisting positioning device and a use method thereof, which solves the problem that the guide frame and the bearing support system are independent of each other and cannot be stably controlled during hoisting.

[0006] To achieve the above object, the present application is implemented by the following technical scheme: The assembly component hoisting positioning device comprises: A positioning guide is fixedly connected with a plurality of reinforcement members and is used to constrain and maintain the relative positions of the reinforcement members; the positioning guide comprises a guide structure extending upward from a connection position, which contacts the assembly component during hoisting and guides the falling path of the assembly component; An auxiliary support is arranged in a central region defined by the positioning guide; a top of the auxiliary support is provided with a support platform for receiving and temporarily supporting the assembly component during the falling process of the assembly component; In the bearing state, the auxiliary support reduces its support height in a controlled manner, and during the reduction of the support height, the assembly component is adjusted in position in the horizontal direction.

[0007] Preferably, it further comprises a support sleeve frame fixedly installed on the reinforcing member for supporting the positioning guide.

[0008] Preferably, the positioning guide comprises two first guide plates and two second guide plates. The two first guide plates are arranged opposite and symmetrically along a first direction, and the two second guide plates are arranged opposite and symmetrically along a second direction perpendicular to the first direction. The first guide plates and the second guide plates are connected end to end to form a rectangular frame.

[0009] Preferably, the first guide plate comprises a first horizontal plate and two first guide side plates. The two first guide side plates extend upward from both ends of the length direction of the first horizontal plate, respectively. At least one U-shaped fastener is arranged on the side of the first horizontal plate for fixed connection with the reinforcing member. Two clearance openings are formed on the bottom surface of the first horizontal plate, and the two clearance openings are arranged adjacent to both ends of the first horizontal plate, respectively.

[0010] Preferably, the second guide plate comprises a second horizontal plate, two second guide side plates, a straight buckle plate and a positioning block. A U-shaped opening is formed in the middle of the second horizontal plate, and the opening side of the U-shaped opening is configured to accommodate the reinforcing member. The straight buckle plate is detachably buckled to the side of the second horizontal plate to close the opening of the U-shaped opening, and both ends of the straight buckle plate are provided with L-shaped buckles. A nut member corresponding to the U-shaped opening is arranged on the straight buckle plate for cooperating with the U-shaped opening to fasten the reinforcing member. The two second guide side plates extend upward from both ends of the length direction of the second horizontal plate, respectively, and are located outside the corresponding first guide side plates. The positioning block is arranged on the inner side of the second guide side plate. The clearance openings on the bottom surface of the first horizontal plate correspond in position to the second horizontal plate.

[0011] A method for hoisting and positioning an assembly component, comprising the following steps: Step S100: installation and positioning step The positioning guide is installed and fixed on a group of reinforcing members to constrain and maintain the relative design positions of the reinforcing members, and the auxiliary support is positioned in the central region surrounded by the positioning guide; Step S200: hoisting and initial guiding step The assembly component is hoisted and initially aligned with the space above the positioning guide, and the guiding structure of the positioning guide contacts the assembly component during the falling process of the assembly component to perform initial guiding and correction; Step S300: receiving and fine adjustment step The assembly component continues to fall under the guidance of the positioning guide until the bottom of the assembly component is received and temporarily supported by the support surface of the auxiliary support; The auxiliary support is controlled to reduce the support height in a controlled manner, so that the assembly component slowly sinks, and the assembly component is fine adjusted in the horizontal direction by the guiding action of the positioning guide during the slow sinking process until the design installation position corresponding to the reinforcing member is reached.

[0012] The present application provides a hoisting and positioning device for assembly components and a method thereof. The present application designs a cooperative positioning system composed of a positioning guide and an auxiliary support, which mechanically contacts and guides the falling assembly component at the initial hoisting stage, realizes automatic and continuous coarse positioning, and actively receives the component weight by the support table on the top of the auxiliary support in the center to make the component quickly stable and avoid continuous swinging. Then, in the fine adjustment stage, the controllable flow characteristics of the granular medium in the foldable outer cylinder are utilized, the fluid leakage member is controlled to be opened, the medium slowly flows out, the support height stably decreases, and the component slightly sinks. During the sinking process, the component bottom automatically generates a small horizontal slip due to the gravity and the constraint of the guiding frame side wall, so that the automatic fine adjustment of the horizontal position is completed while the vertical sinking is realized. The high-risk manual pry rod fine adjustment is changed into safe and controllable mechanical automatic fine adjustment, and the construction personnel do not need to perform high-risk operations near the suspended heavy object, so that the personal safety is fundamentally guaranteed. At the same time, the design of the guide and the support makes the component stable and controlled during the positioning process, eliminates the impact on the guiding structure, and avoids the problem of easy deformation and damage of the existing guiding frame.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application. EMBODIMENT

[0017] As Figures 1-6 shown, the embodiment of the present application provides a hoisting positioning device for the hoisting assembly of a concrete member, which comprises a positioning guide 3 and an auxiliary support 5.

[0018] The positioning guide 3 is fixedly connected with the plurality of reinforcing members 2, which realizes the installation of the positioning guide 3 and the reinforcing members 2, and is also used for restraining and maintaining the relative positions of the reinforcing members 2, solving the low position precision caused by the deformation of the reinforcing members 2 in the pouring process. The bottom of the assembly member is provided with a plurality of insertion holes corresponding to the reinforcing members 2, which can realize the synchronous docking of the reinforcing members 2 and the insertion holes (the reinforcing members 2 are inserted into the insertion holes correspondingly). The positioning guide 3 comprises a guide structure extending upward from the connection position, which is in contact with the assembly member in the hoisting process and guides the falling path of the assembly member. For example, the guide structure has an inwardly extending inclined surface (from top to bottom direction), and the bottom of the assembly member contacts the inclined surface, so that the assembly member moves towards the center. The auxiliary support 5 is arranged in the central area defined by the positioning guide 3 and is supported by the base 1 (referring to the installed lower pile body or the poured concrete bottom plate). The top of the auxiliary support 5 is provided with a support table 503a for supporting and temporarily supporting the assembly member during the falling process of the assembly member. The auxiliary support 5 enables the assembly member to be stably lowered, and the assembly member is more stable and safe during construction compared with the traditional suspended assembly member in the hoisted state.

[0019] The auxiliary support 5 reduces its support height in a controlled manner in the bearing state. The user slowly controls the height reduction of the auxiliary support 5, so that the assembly member slowly moves downward, ensuring the stability of the downward movement of the assembly member. During the process of reducing the support height, the assembly member adjusts the position in the horizontal direction, which can be assisted by manual or guided by the positioning guide 3, both of which are for the purpose of completing the precise docking of the assembly member in the final falling stage (the reinforcing members 2 are inserted into the insertion holes correspondingly).

[0020] In an embodiment, a support sleeve frame 4 is also designed, which is fixedly installed on the reinforcing member 2 and is used for supporting the positioning guide 3.

[0021] As Figure 2 shown, the positioning guide 3 is installed on the reinforcing member 2, which is easy to slide in the installation position when receiving a strong downward force, and the positioning guide 3 itself slides downward, causing the installation failure of the positioning guide 3. The support sleeve frame 4 is composed of two blocks, which are clamped on the reinforcing member 2 at the corner by means of a tensioning screw rod, and is used for supporting the positioning guide 3 to avoid the downward sliding of the positioning guide 3.

[0022] In one embodiment, the positioning guide 3 includes two first guide plates 301 and two second guide plates 302; the two first guide plates 301 are arranged opposite to each other and symmetrically along a first direction, and the two second guide plates 302 are arranged opposite to each other and symmetrically along a second direction perpendicular to the first direction.

[0023] The first guide plate 301 and the second guide plate 302 are connected end to end to form a rectangular frame; or the first guide plate 301 and the second guide plate 302 are arranged in a "well" shape to form a rectangular frame.

[0024] It is understandable that the steel reinforcement members 2 on the base 1 are generally distributed in a frame, and the design of the first guide plate 301 and the second guide plate 302 is also in a frame structure, so that the steel reinforcement members 2 can be connected together.

[0025] In one embodiment, the first guide plate 301 includes a first horizontal plate 301a and two first guide side plates 301b. The two first guide side plates 301b extend upward from both ends of the first horizontal plate 301a along its length. The top of the first guide side plate 301b is provided with a guide slope and the bottom is provided with a guide vertical surface. The guide slope has a wide opening structure, which can guide the assembly fastener into the inner side of the guide vertical surface. Based on the guide vertical surface, the assembly component is initially positioned. The side of the first horizontal plate 301a is provided with at least one U-shaped fastener 301c for fixed connection with the reinforcing bar 2. The U-shaped fastener 301c is a U-bolt. The side of the first horizontal plate 301a has double holes for installing the U-bolt. The position design of the double holes meets the position distribution requirements of the standard reinforcing bar 2. After the reinforcing bar 2 is installed on the first horizontal plate 301a using the U-shaped fastener 301c, each reinforcing bar 2 is positioned.

[0026] The bottom surface of the first horizontal plate 301a has two clearance openings 301d, which are respectively located near the two ends of the first horizontal plate 301a. The two clearance openings 301d correspond to the second horizontal plate 302a of the second guide plate 302.

[0027] It is understandable that the first horizontal plate 301a and the two first guide side plates 301b are an integral structure.

[0028] In an embodiment, the second guiding plate member 302 adopts a locking design to adapt to different installation requirements; the second guiding plate member 302 comprises a second horizontal plate 302a, two second guiding side plates 302b, a straight clamping plate 302c and a positioning block 302f; the middle part of the second horizontal plate 302a is provided with a U-shaped opening 302d, and the opening side of the U-shaped opening 302d is used to directly accommodate the reinforcing bar member 2; in order to lock the reinforcing bar member 2 in the U-shaped opening 302d, a detachable straight clamping plate 302c is designed; the straight clamping plate 302c can be clamped on the side of the second horizontal plate 302a provided with the U-shaped opening 302d, so as to close the opening of the U-shaped opening; the two ends of the straight clamping plate 302c are provided with L-shaped clamping members 302e for preliminary positioning; when fastened, the reinforcing bar member 2 can be clamped in the U-shaped opening 302d by rotating the nut member (for example, cooperating with the bolt penetrating through the straight clamping plate and the second horizontal plate) provided on the straight clamping plate 302c or the second horizontal plate 302a; the two second guiding side plates 302b extend upward from the two ends of the second horizontal plate 302a, and are installed outside the corresponding first guiding side plates 301b, forming double guiding walls. The inner side of the second guiding side plate 302b is provided with a positioning block 302f, which can be used for accurate positioning. The position of the gap 301d on the first horizontal plate 301a corresponds to the position of the second horizontal plate 302a, so as to ensure that the two do not interfere with each other in the vertical space, and are tightly assembled.

[0029] The auxiliary support member 5 is arranged in the central area surrounded by the positioning guiding member 3. In a preferred embodiment, the auxiliary support member 5 comprises a support base 501, a foldable outer cylinder member 502 and a central support member 503.

[0030] The support base 501 is a solid block structure (such as a concrete block or a steel block), which is arranged on the ground or the foundation pile to stably support the foldable outer cylinder member 502 and protect the bottom of the foldable outer cylinder member 502 from being damaged. The lower end of the foldable outer cylinder member 502 is arranged on the support base 501. The inside of the foldable outer cylinder member 502 is filled with granular medium, such as dry fine sand, standard steel balls or engineering plastic particles. The medium has load bearing capacity in static state and can flow like fluid when disturbed. The foldable outer cylinder member 502 can comprise a telescopic folding cylinder 502a (for example, made of a metal shell with folds) to adapt to the change of the internal volume. The top of the folding cylinder 502a is fixedly provided with a top support ring 502b through flange or welding, and the center of the top support ring 502b is provided with a central opening 502c. A fluid leakage member 502d is arranged on the cylinder wall of the folding cylinder 502a close to the top, and the fluid leakage member 502d can be a manual valve, an electrically controlled valve or a porous plug, which is used to release the granular medium in the cylinder in a controlled manner.

[0031] The lower part of the center support 503 (i.e. the "well" type column 503c) passes through the center opening 502c of the top support ring 502b and is inserted into the granular medium within the foldable outer cylinder 502. The top end of the center support 503 extends outside the cylinder and is provided with a support platform 503a, the upper surface of which is the support surface for receiving the upper assembly component. At the top center of the support platform 503a, a downwardly recessed laser positioning member 503b can be provided for reflecting the laser beam to provide an accurate elevation and center position measurement reference for the total station. The lower end of the "well" type column 503c is usually provided with a guide bevel 503d to facilitate its initial insertion into the granular medium. Embodiments

[0032] The present embodiment provides a method for hoisting and positioning an assembly component, which uses the hoisting and positioning device for assembly components in Embodiment One, and includes the following steps: Step S100: installation and positioning step First, at the designated position of the completed lower structure, the reserved steel reinforcement 2 is preliminarily arranged and reviewed. Then, the positioning guide 3 is installed. Specifically, the two first guide plate members 301 are respectively clamped on two main steel reinforcements arranged in the longitudinal direction by the U-shaped fasteners 301c on the sides of the first guide plate members 301, and are preliminarily fixed using bolts. Then, the two second guide plate members 302 are taken, and the U-shaped openings 302d in the middle of the plate members are clamped into the other two main steel reinforcements arranged in the transverse direction from top to bottom. Then, the matching straight buckles 302c are buckled to the sides of the second transverse plate 302a, and after preliminary positioning using the L-shaped buckles 302e at both ends of the straight buckles, the corresponding fastening nuts are tightened to firmly clamp the steel reinforcements in the U-shaped openings. During installation, it is necessary to ensure that the two clearance openings 301d at the bottom of the first transverse plate 301a accurately correspond to the actual installation position of the second transverse plate 302a, so that all the guide plate members are connected end to end to finally form a rectangular guide frame that is regular in shape and solid and reliable. This frame not only locks the relative spatial relationship of all the steel reinforcements, but also provides a physical guide boundary for subsequent hoisting. Finally, the auxiliary support 5 is hoisted to the center area of the guide frame and placed securely to ensure that the support base 501 is stably grounded and the support platform 503a at the top is at an appropriate initial height.

[0033] Step S200: hoisting and initial guiding step The upper assembly member to be installed, such as a precast pipe pile or a pile cap member, is lifted by a lifting device. An operator guides the crane to roughly align the bottom contour of the member with the space above the rectangular guide frame formed by the positioning guide 3, and then slowly lowers the member at a controlled speed. During the lowering process, when the bottom edge of the member comes into contact with the guide surface of any first guide side plate 301b or second guide side plate 302b, the member will automatically generate a tendency to move towards the center of the frame under the action of the inclined contact force, thereby passively correcting its falling posture and planar position. This mechanical preliminary guiding and correction process significantly reduces the high-frequency and slight adjustment operations on the lifting device, enabling the member to be smoothly and automatically guided into the predetermined landing area.

[0034] Step S300: receiving and fine adjustment step As the member continues to fall, its bottom eventually smoothly sits on the support platform 503a on top of the auxiliary support 5. At this time, the entire or main weight of the member is borne by the auxiliary support, the hook load is released, and the member reaches the initial static stability. Subsequently, the precise positioning program is started: through manual or automatic control, the fluid leakage member 502d provided on the side wall of the foldable outer cylinder member 502 is slowly opened, so that the granular medium filled in the interior thereof begins to be discharged outward at a controllable speed. As the amount of medium decreases, the internal volume of the foldable outer cylinder shrinks, driving the internal center support 503 and the support platform on top thereof together with the member to synchronously sink at a millimeter-per-minute level. The core fine adjustment effect is achieved in this process: while the member slowly sinks with the support platform, due to the vertical downward force generated by the weight of the member and the small gap and friction between the side surface of the member and the guide surface of the positioning guide, the member will spontaneously generate a small amount of horizontal slip or rotation under the spatial constraint of the guide frame, thereby automatically correcting its final planar coordinates. The construction personnel can monitor the three-dimensional position of the member in real time by means of the laser signal reflected by the center laser positioning member 503b of the support platform, and control the sinking process by adjusting the fluid leakage speed, or supplement with a small amount of external force for fine adjustment if necessary, until the planar position, elevation and perpendicularity of the member all fully meet the design installation requirements. After the fine adjustment is completed, subsequent processes such as steel bar connection, welding or grouting fixation can be performed, and after all the positioning work is completed, the positioning guide and the auxiliary support can be disassembled, cleaned and recycled for use at the next work site.

[0035] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
