Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to the construction and construction method of a turnover facility after the removal of the formwork support frame inside a floor. Background Technology

[0002] In recent years, the construction industry has continued to develop, and both architectural styles and floor heights have been constantly evolving. However, what remains unchanged is the management of project schedule and performance. High-rise and multi-story reinforced concrete structures involve the dismantling and reuse of the formwork system of the lower structure.

[0003] Traditionally, the turnover and transportation of dismantled formwork materials within a building rely on manual labor via an unloading platform. This requires manual handling of dismantled formwork, timber, and support materials within the building to the unloading platform, where they are then transported to the construction floor by vertical transport equipment. This traditional construction method is labor-intensive, inefficient, and poses numerous safety hazards and risks, making it inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a structure and construction method for a reusable facility after the removal of the formwork support frame inside a floor, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a structure for a reusable facility after the removal of the formwork support frame inside a floor, the structure comprising:

[0006] A supporting beam frame is provided, with a cantilevered bracket horizontally assembled on one side of the supporting beam frame, and the cantilevered bracket is inserted into the unloading platform;

[0007] A track assembly, wherein the track is horizontally positioned above the supporting beam and the cantilever support, and the track assembly includes a movable track frame;

[0008] A support for a movable component is horizontally movably mounted above a movable rail frame. The support for the movable component includes a movable placement vehicle and four movable rollers.

[0009] The drive control assembly includes a traction assembly seat, a horizontal adaptation rod, and a traction control rope. The traction assembly seat is located at the center of the lower end of the mobile placement vehicle. The horizontal adaptation rod is horizontally movably inserted through the traction assembly seat, and both sides of the traction control rope are connected to the two ends of the horizontal adaptation rod that pass through the traction assembly seat.

[0010] Preferably, the supporting beam frame includes four support beams, and several truss braces are inclinedly assembled between the four support beams. The cantilever bracket is arranged in a triangular structure, and the upper end of the cantilever bracket is flush with the upper end of the supporting beam frame.

[0011] Preferably, the movable rail frame includes two solid rails and several crossbeams, and the two solid rails and the opposite sides of the upper end of the cantilever support are solid steel pipes filled with C25 concrete.

[0012] Preferably, the mobile placement vehicle has four wheel frames vertically and symmetrically arranged at its lower end. Each of the four wheel frames has a horizontally rotating shaft at its lower end via a bearing. The four moving rollers are respectively sleeved on the four rotating shafts, and the lower ends of the four moving rollers are in contact with the upper ends of the two solid rails.

[0013] Preferably, both sides of the upper end of the cantilever support are vertically provided with constraint blocks. When the mobile placement vehicle is horizontally placed in the center of the building unloading platform, the two moving rollers at the lower end of the mobile placement vehicle abut against the constraint blocks respectively.

[0014] Preferably, each of the wheel frames is provided with a stabilizing surround bar on one side of its lower end. The stabilizing surround bars are all L-shaped structures, and the four stabilizing surround bars are slidably connected to the lower ends of the two solid rails respectively.

[0015] Preferably, the lower center of the mobile placement vehicle is provided with a bolt mounting seat, the traction assembly seat is vertically provided at the lower end of the bolt mounting seat by a number of bolts, the lower end of the traction assembly seat is provided with an adaptation connecting seat, and a sliding rod groove is horizontally opened through the adaptation connecting seat, and the horizontal adaptation rod moves horizontally through the sliding rod groove.

[0016] Preferably, the horizontal adapting rod has end pressure plates on both sides of the adapting connecting seat, and a buffer spring is sleeved between the end pressure plate and the adapting connecting seat on the horizontal adapting rod, with the two sides of the buffer spring contacting the end pressure plate and the adapting connecting seat respectively.

[0017] Preferably, a drive box is horizontally mounted on the side of the support beam away from the cantilever bracket via an installation frame. A control turntable is mounted on one side of the drive box's conveyor shaft. The control rope is taut and overlapped with the control turntable on the side away from the horizontal adaptation rod. A reversing shaft is horizontally mounted on one side of the upper end of the cantilever bracket, and the end of the control rope away from the control turntable passes around the reversing shaft and connects to the horizontal adaptation rod.

[0018] A method for the construction of temporary facilities after the removal of formwork scaffolding within a floor, the method being applied to the construction of temporary facilities after the removal of formwork scaffolding within a floor, includes the following steps:

[0019] Step 1: After the floor structure strength meets the conditions for demolding, manually stack the formwork in situ.

[0020] Step 2: Assemble the support beam and truss brace using fasteners to form a support beam frame. Then, assemble the support beam frame and cantilever bracket, and insert the assembled cantilever bracket into the unloading platform.

[0021] Step 3: Construct the mobile rail frame and the mobile placement vehicle in sequence, and slide the mobile placement vehicle to the mobile rail frame from one side. The four moving rollers roll in contact with the upper ends of the two solid rails of the mobile rail frame, and the four stabilizing surround rods provide stable guidance for the connection between the mobile placement vehicle and the mobile rail frame.

[0022] Step 4: Before connecting the mobile placement vehicle to the cantilever support, assemble the traction assembly seat and the horizontal adaptation rod with the mobile placement vehicle. After the traction assembly seat is assembled, connect the two ends of the traction control rope to the two ends of the horizontal adaptation rod respectively. Then install the drive box with the control turntable and tighten the traction control rope and the control turntable.

[0023] Step 5: The template support stack is transported within the building using a simple forklift and placed on top of the mobile placement vehicle. As the control turntable rotates, the mobile placement vehicle and the placed template support stack are pulled to the unloading platform and then hoisted and transferred using the upper-level hoisting equipment.

[0024] Step Six: When the mobile placement vehicle moves above the cantilever support, it stops at a suitable position under the limiting action of the constraint block. At the same time, the inertial rotation of the control turntable is effectively unloaded by the horizontal movement of the two horizontal adaptation rods and the elastic support of the buffer spring. Furthermore, the mobile placement vehicle runs stably under the action of the stabilizing surround rod.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] After the floor structure strength meets the demolding conditions, the formwork supports are stacked and placed. Then, support beams, cantilever supports, mobile rails, and mobile placement vehicles are assembled on site to form a horizontal moving structure for the stacked formwork supports within the floor. With the help of drive control components, labor costs are saved and construction efficiency is improved. Then, with the cooperation of stabilizing surround rods and restraint blocks, the mobile placement vehicles are positioned and limited for transportation and use, improving construction safety and making them convenient for reuse.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see the appendix Figure 1-8 This application provides the following technical solutions.

[0038] Example 1: A construction method and structure of a turnover facility after the dismantling of the formwork support frame inside a floor, including a support beam frame 1, a cantilever bracket 2 horizontally assembled on one side of the support beam frame 1, the cantilever bracket 2 cantilevered into the unloading platform, the track is horizontally set above the support beam frame 1 and the cantilever bracket 2, the track assembly includes a movable rail frame 3, the support beam frame 1 includes four support beams 22, and several truss braces 23 are inclinedly assembled between the four support beams 22, the cantilever bracket 2 is set in a triangular structure, the upper end of the cantilever bracket 2 is flush with the upper end of the support beam frame 1, and the length of the cantilever bracket 2 inserted into the unloading platform is set according to actual needs to facilitate the later hoisting of the formwork support frame stack;

[0039] The movable track frame 3 includes two solid rails 4 and several crossbeams. The two solid rails 4 and the two opposite sides of the upper end of the cantilever support 2 are solid steel pipes filled with C25 concrete. The nodes of the support beam frame 1 and the cantilever support 2 can be connected by right-angle fasteners, swivel fasteners, or butt fasteners. The cantilever support 2 can be erected or welded in the same way. On-site erection is simple and convenient, and the concrete poured into the solid rails 4 increases the support strength of the solid rails 4.

[0040] Example 2: Based on Example 1, a supporting moving component is set up for the horizontal movement of the template support stack. The supporting moving component is horizontally movable above the moving rail frame 3. The supporting moving component includes a moving placement vehicle 5 and four moving rollers 8. The lower end of the moving placement vehicle 5 is vertically and symmetrically provided with four wheel frames 6. The lower end of each of the four wheel frames 6 is horizontally provided with a rotating shaft 7 through a bearing. The four moving rollers 8 are respectively sleeved on the four rotating shafts 7, and the lower ends of the four moving rollers 8 are respectively in contact with the upper ends of the two solid rails 4. The upper ends of the cantilever support 2 are vertically provided with constraint blocks 10 on both sides. When the moving placement vehicle 5 is horizontally placed in the center of the building unloading platform, the two moving rollers 8 at the lower end of the moving placement vehicle 5 abut against the constraint blocks 10 respectively. When the moving placement vehicle 5 slides horizontally above the solid rails 4 of the moving rail frame 3 through the moving rollers 8, it can be limited to move by the constraint blocks 10 when it reaches the unloading platform, which improves the safety of construction and the connection convenience of hoisting.

[0041] Each of the wheel frames 6 is provided with a stabilizing surround rod 9 on one side of its lower end. The stabilizing surround rods 9 are all L-shaped structures, and the four stabilizing surround rods 9 are slidably hooked to the lower ends of the two solid rails 4 respectively. When the template support stack is placed on the mobile placement vehicle 5, the mobile placement vehicle 5 will not tilt or detach from the mobile rail frame 3. When the mobile placement vehicle 5 moves horizontally on the mobile rail frame 3, it will also not tilt or misalign, thus improving the stability of the movement.

[0042] In this embodiment:

[0043] Example 3: Based on Example 2, a drive control component is provided to drive the horizontal movement of the mobile placement vehicle 5. The drive control component includes a traction assembly seat 13, a horizontal adaptation rod 16, and a traction control rope 21. The traction assembly seat 13 is located at the lower center of the mobile placement vehicle 5. The horizontal adaptation rod 16 is horizontally movably inserted through the traction assembly seat 13, and both sides of the traction control rope 21 are connected to the two ends of the horizontal adaptation rod 16 that pass through the traction assembly seat 13. A bolt mounting seat 12 is horizontally provided at the lower center of the mobile placement vehicle 5. The traction assembly seat 13 is vertically provided at the lower end of the bolt mounting seat 12 by several bolts. An adaptation connecting seat 14 is horizontally provided at the lower end of the traction assembly seat 13. A sliding rod groove 15 is provided through the horizontal adaptation rod 16, which moves horizontally through the sliding rod groove 15. Both sides of the horizontal adaptation rod 16 are provided with end pressure plates 17. Buffer springs 18 are sleeved between the end pressure plates 17 and the adaptation connection seat 14 on the horizontal adaptation rod 16, and both sides of the buffer springs 18 are in contact with the end pressure plates 17 and the adaptation connection seat 14 respectively. When the pull control rope 21 pulls the horizontal adaptation rod 16 to control the movement of the mobile placement vehicle 5, and when the mobile placement vehicle 5 moves to a limited position by the constraint block 10, the inertial rotation of the control turntable 20 will not over-pull the mobile placement vehicle 5, thereby improving the durability of the pull control rope 21 and the safety of the mobile placement vehicle 5.

[0044] The support beam 1 is horizontally mounted with a drive box 19 on the side away from the cantilever bracket 2 via an installation frame. A control turntable 20 is provided on one side of the drive box 19's conveyor shaft. The pull control rope 21 is tensioned and overlapped with the control turntable 20 on the side away from the horizontal adaptation rod 16. A reversing shaft 11 is horizontally provided on one side of the upper end of the cantilever bracket 2, and the end of the pull control rope 21 away from the control turntable 20 passes around the reversing shaft 11 and connects to the horizontal adaptation rod 16. The drive box 19 is equipped with a servo drive motor, which is common in the prior art. When the mobile placement vehicle 5 needs to move, the drive box 19 controls the control turntable 20 to pull the pull control rope 21. In addition, a tensioning auxiliary mechanism can be provided on one side of the pull control rope 21. Alternatively, the pull control rope 21 and the control turntable 20 can be respectively set as a chain and a sprocket mechanism to ensure the normal movement of the mobile placement vehicle 5.

[0045] A method for reusing formwork after its removal from a floor, comprising the following steps:

[0046] Step 1: After the floor structure strength meets the conditions for demolding, manually stack the formwork in situ.

[0047] Step 2: Assemble the support beam 22 and the truss brace 23 using fasteners to form the support beam frame 1. Then, assemble the support beam frame 1 and the cantilever bracket 2 and insert the assembled cantilever bracket 2 into the unloading platform. The nodes are connected using right-angle fasteners, swivel fasteners, and butt fasteners.

[0048] Step 3: Construct the mobile rail frame 3 and the mobile placement vehicle 5 in sequence, and slide the mobile placement vehicle 5 to the mobile rail frame 3 from one side. The four mobile rollers 8 roll in contact with the upper ends of the two solid rails 4 of the mobile rail frame 3, and the four stabilizing surround rods 9 provide stable guidance for the connection between the mobile placement vehicle 5 and the mobile rail frame 3.

[0049] Step 4: Before connecting the mobile placement vehicle 5 to the cantilever bracket 2, assemble the traction assembly seat 13 and the horizontal adaptation rod 16 with the mobile placement vehicle 5. After the traction assembly seat 13 is assembled, connect the two ends of the traction control rope 21 to the two ends of the horizontal adaptation rod 16 respectively. Then install the drive box 19 with the control turntable 20 and tighten the traction control rope 21 and the control turntable 20.

[0050] Step 5: The template support stack is transported within the floor using a simple forklift and placed on top of the mobile placement vehicle 5. As the control turntable 20 rotates, the mobile placement vehicle 5 and the placed template support stack are pulled to the unloading platform and then hoisted and transferred by the upper hoisting equipment.

[0051] Step Six: When the mobile placement vehicle 5 travels above the cantilever bracket 2, under the limiting action of the constraint block 10, the mobile placement vehicle 5 stops at a suitable position. At the same time, the inertial rotation of the control turntable 20 is effectively unloaded by the horizontal movement of the two horizontal adaptation rods 16 and the elastic support of the buffer spring 18. Furthermore, under the engagement action of the stabilizing surround rod 9, the mobile placement vehicle 5 runs stably.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
