Description

Technical Field

[0002] In the existing construction method of casting secondary structures on primary structures, generally, post-inserted bars are first used, formwork is supported by wooden boards, and then concrete is poured. It is difficult to vibrate, and the wooden formwork is easily loosened when knocked. After the concrete of the secondary structure lacking vibration solidifies, there are certain quality problems. Therefore, upper and lower hoops and positioning guide rods are adopted. A winch is set on the ground, a fixed pulley is installed outside the reinforcement cage limiting plate, and the steel formwork is lifted by the steel wire rope of the winch passing around the fixed pulley. This method occupies a large area and relies on upper hoops, lower hoops and guide rods, and is difficult to be used in irregular primary structures. Moreover, each time the formwork is lifted, the components around the formwork need to be adjusted manually, and the operation is troublesome. Summary of the Invention

[0042] As Figures 1 to 6 shown, a method for constructing a secondary structure of the present invention is characterized in that: the method includes the following steps:

[0043] Step 1: Fix the secondary structure steel reinforcement cage;

[0044] In actual operation, the secondary structure steel reinforcement cage can be pre - bundled on the primary structure, and the bundling parts are gradually removed as the pouring height at the bottom increases.

[0045] Step 2: Install the secondary structure formwork robot, wherein the secondary structure formwork 16 is located on the outer side of the lower part of the secondary structure steel reinforcement cage;

[0046] The secondary structure formwork robot includes a formwork mechanism clamped outside the primary structure 23. The formwork mechanism includes a plurality of attachment members arranged circumferentially outside the primary structure 23 and all cooperating with the external corners of the primary structure 23. Two adjacent attachment members are connected by a screw rod 11. The attachment member includes a clamping plate 1 cooperating with the outer surface of the primary structure 23. The clamping plate 1 is an angle plate structure composed of two support plates. On the outer sides of the two support plates of the clamping plate 1, there are a first mounting plate 2 and a second mounting plate 3. On the side of the first mounting plate 2 facing the corresponding support plate, there are a first inner plate 4 and a first outer plate 6. An electric motor 8 is installed on the outer side of the first outer plate 6. A driving gear 9 is installed on the output shaft of the electric motor 8. A driven gear 10 meshing with the driving gear 9 is arranged on the screw rod 11. On the side of the second mounting plate 3 facing the corresponding support plate, there are a second inner plate 5 and a second outer plate 7. Electric spring-driven wheels 13 abutting against the outer surface of the primary structure 23 are installed on the sides of the first inner plate 4 and the second inner plate 5 facing the primary structure 23. Locking nuts 12 cooperating with the screw rod 11 are fixed on the sides of the first mounting plate 2 and the second mounting plate 3 away from the corresponding support plates. One end of the screw rod 11 is in threaded cooperation with the locking nut 12 outside the first mounting plate 2 of one of the two adjacent attachment members, and the other end of the screw rod 11 is in threaded cooperation with the locking nut 12 outside the second mounting plate 3 of the other of the two adjacent attachment members;

[0047] On the secondary structure formwork 16, there are connection rings 17 through which the screw rods 11 at corresponding positions are inserted and cooperated. Electric telescopic rods 14 abutting against the primary structure 23 are installed on the sides of the first inner plate 4 and the second inner plate 5 on both sides of the secondary structure formwork 16 facing the primary structure 23. Formwork knocking mechanisms for knocking the secondary structure formwork 16 are installed on the sides of the first inner plate 4 and the second inner plate 5 on both sides of the secondary structure formwork 16 away from the primary structure 23. An attached vibrator is installed on the secondary structure formwork 16;

[0048] Step 3: The electric motor 8 rotates forward to clamp the primary structure 23 by the secondary structure formwork robot. At this time, the electric telescopic rod 14 is in a retracted state, and the secondary structure formwork 16 is closely attached to the primary structure 23;

[0049] Step 4: Construct one section of the secondary structure: Pour concrete into the secondary structure formwork 16 from the top of the secondary structure formwork 16, and use the attached vibrator to vibrate the concrete evenly. After the concrete reaches the preset strength, obtain one section of the secondary structure;

[0050] Step 5: Pre-demould the secondary structure formwork 16: Use the formwork knocking mechanisms on both sides of the secondary structure formwork 16 to knock the secondary structure formwork 16 multiple times to achieve pre-demoulding of the secondary structure formwork 16;

[0051] Step 6, Demoulding of the secondary structure formwork 16: Control the electric telescopic rods 14 on both sides of the secondary structure formwork 16 to extend, push the secondary structure formwork 16, and at the same time, reverse the motor 8 for demoulding. Among them, the pushing distance of the electric telescopic rod 14 is 1 mm to 2 mm, and the distance between the two locking nuts 12 at both ends of the screw rod 11 increases by 1 mm to 2 mm, ensuring that the secondary structure formwork robot is stable on the primary structure 23;

[0052] Step 7, The secondary structure formwork robot climbs once: While the electric telescopic rod 14 retracts, the secondary structure formwork robot uses multiple electric spring drive wheels 13 to climb once along the outer surface of the primary structure 23 from bottom to top. The climbing height of the secondary structure formwork robot once is less than the height of the secondary structure formwork 16;

[0053] Step 8, Repeat Steps 3 to 7 multiple times until the secondary structure construction is completed.

[0054] It should be noted that the formwork robot is assembled and installed on the primary structure once. The motor drives the driving gear to rotate. The driving gear meshes with the driven gear to adjust the contraction and expansion of multiple attachment parts. The electric telescopic rod and the formwork knocking mechanism are used for demoulding. The electric spring drive wheels with elastic allowance are used to climb up and down along the height direction of the primary structure to realize the rise of the secondary structure formwork, with high automation, small volume, flexible operation and high efficiency.

[0055] In this embodiment, the number of formwork carrying mechanisms is multiple, and the multiple formwork carrying mechanisms are arranged in a vertically parallel structure on the outside of the primary structure 23.

[0056] It should be noted that multiple formwork carrying mechanisms can improve the load-carrying capacity of the formwork robot.

[0057] In this embodiment, the formwork knocking mechanism includes an electric ball hinge support 15, a first connecting rod 19, a hinge shaft 20, a second connecting rod 21, and a knocking hammer 22 connected in sequence. The hinge structure can expand the knocking range of the knocking hammer 22.

[0058] In this embodiment, the thread directions at both ends of the screw rod 11 are opposite.

[0059] In this embodiment, the included angle between the two support plates of the clamping plate 1 is greater than 0° and less than 180°, which can meet the construction of the secondary structure on the special-shaped primary structure.

[0060] In this embodiment, when the first mounting plate 2 is not perpendicular to the first outer plate 6, a triangular spacer 18 is fixed on the outside of the first mounting plate 2, the locking nut 12 is fixed on the outside of the triangular spacer 18, and an internal thread matching the corresponding screw rod is provided in the triangular spacer 18;

[0061] When the second mounting plate 3 is not perpendicular to the second outer plate 7, a triangular cushion block 18 is fixed on the outside of the second mounting plate 3, a locking nut 12 is fixed on the outside of the triangular cushion block 18, and an internal thread matching the corresponding screw is provided in the triangular cushion block 18.

[0062] In this embodiment, the primary structure 23 has an internal corner, and an internal corner auxiliary member is fixedly arranged at the position of the internal corner. The internal corner auxiliary member includes two auxiliary flat plates 24 adapted to the internal corner. One end of the auxiliary flat plate 24 away from the internal corner is provided with a track plate 25 perpendicular to the auxiliary flat plate 24. One end of the track plate 25 away from the auxiliary flat plate 24 and on the side facing the internal corner is provided with a limiting plate 26 perpendicular to the track plate 25. The formwork mechanism further includes an accessory adapted to the internal corner of the primary structure 23. The accessory is connected to two adjacent attachment members through a screw 11. The accessory includes a first connecting plate 27 and a second connecting plate 28 connected to each other. One end of the first connecting plate 27 away from the second connecting plate 28 and one end of the second connecting plate 28 away from the first connecting plate 27 respectively extend into the internal corner auxiliary member. Electric spring driving wheels 13 abutting against the track plate 25 are respectively installed at positions of the first connecting plate 27 and the second connecting plate 28 facing the track plate 25. Locking nuts 12 matching the screw 11 are installed on the side surfaces of the first connecting plate 27 and the second connecting plate 28 facing the internal corner. A motor 8 is installed on the outside of the second outer plate 7 adjacent to the accessory. A driving gear 9 installed on the output shaft of the motor 8 meshes with a driven gear 10 on the screw 11. The cooperation of the internal corner auxiliary member and the accessory meets the construction of the secondary structure in the special-shaped primary structure with an internal corner.

[0063] When the primary structure 23 has an internal corner, in step seven, while the electric telescopic rod 14 retracts, the attachment members in the secondary structure formwork robot climb up along the outer surface of the primary structure 23 from bottom to top once by using a plurality of electric spring driving wheels 13, and the accessory in the secondary structure formwork robot climbs up along the inner surface of the track plate 25 from bottom to top once by using the electric spring driving wheels 13. The climbing height of the secondary structure formwork robot once is less than the height of the secondary structure formwork 16.
