They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] like Figure 1-5 As shown, the utility model provides a trackless hydraulic self-climbing formwork system, comprising a climbing frame 2 and a climbing formwork 1 arranged above the climbing frame 2, wherein the climbing frame 2 is located at a concrete section of a cast object 3, and the formwork is located at a concrete section to be cast. The trackless hydraulic self-climbing formwork system comprises:

[0032] A climbing rail 201, which is fixedly arranged on a side of the climbing frame 2 close to the cast object 3;

[0033] A sliding system is installed on the poured concrete section along the height direction of the poured object 3, and the climbing rail 201 is movably arranged on the sliding system;

[0034] A hydraulic cylinder 4, the bottom of which is connected to the sliding system, and a piston rod 401 is connected to the climbing rail 201, and the climbing frame 2 and the climbing formwork 1 are driven to climb by the hydraulic cylinder 4;

[0035] Anchor piece 6 is used to anchor the climbing frame 2 to the poured concrete section.

[0036] In the above technical solution, if Figure 1As shown, the trackless hydraulic self-climbing formwork system consists of a climbing frame 2, a climbing formwork 1, a climbing rail 201, a sliding system and a hydraulic cylinder 4. The sliding system, the climbing rail 201 and the hydraulic cylinder 4 are installed in multiple groups according to the size of the climbing frame 2. The sliding system is installed on the poured concrete section of the cast object 3. The climbing frame 2 is located below the climbing formwork 1, and the climbing rail 201 is fixed on the climbing frame 2. A hydraulic cylinder 4 is installed between the sliding system and the climbing rail 201. The climbing frame 2 and the climbing formwork 1 are gradually lifted by the reciprocating motion of the hydraulic cylinder 4. Specifically: during the lifting operation, the hydraulic cylinder 4 is started to extend the piston rod 401. The climbing rail 201 connected to the piston rod 401 will drive the climbing frame 2 and the climbing formwork 1 to move upward along the setting direction of the sliding system under the jacking action of the piston rod 401, thereby realizing the lifting of the climbing frame 2 and the climbing formwork 1. When the climbing formwork 1 climbs to After the climbing frame 2 is in position, the climbing frame 2 is temporarily anchored to the poured concrete section through the anchor 6, so that the hydraulic self-climbing formwork system is in the current lifting position, and the piston rod 401 of the hydraulic cylinder 4 is retracted. After the concrete construction and demoulding are completed, the connection between the anchor 6 and the climbing frame 2 is released, so that the climbing frame 2 is in a free state and then the hydraulic cylinder 4 is driven to extend the piston rod 401 to lift the climbing frame 2 and the climbing formwork 1 again. After each layer of concrete is poured, the anchor 6, the sliding system and the hydraulic cylinder 4 need to be installed in the concrete section of that layer to ensure the smooth progress of the subsequent lifting operation. The utility model integrates the climbing rail 201 into the climbing frame 2, and the hydraulic cylinder 4 is placed on the sliding system. The climbing frame 2 and the climbing formwork 1 are gradually lifted through the reciprocating motion of the hydraulic cylinder 4. During the lifting operation, there is no need for the staff to frequently operate the reversing operation, and the operation efficiency is high and the labor intensity is low.

[0037] In another technical solution, the anchor 6 includes an embedded part 801 embedded in the concrete, and a high-strength bolt 802 threadedly connected to the embedded part 801, the end of the high-strength bolt 802 extends out of the surface of the concrete to form an anchor end, and the anchor end of the high-strength bolt 802 is connected to the main beam 202 of the climbing frame 2.

[0038] In the present technical solution, an anchor hole can be opened at the end of the main cross beam 202 of the climbing frame 2. After the climbing formwork 1 is climbed into place, the high-strength bolt 802 is passed through the anchor hole and threadedly connected to the embedded part 801 to anchor the climbing frame 2 to the poured concrete section. When the climbing formwork 1 needs to climb, the high-strength bolt 802 can be removed to make the climbing frame 2 in a free state, which is easy to operate; the embedded part 801 can be a sleeve.

[0039] In another technical solution, Figure 2 , Figure 3As shown, a hanging plate 204 is provided at the end of the main cross beam 202 of the climbing frame 2, and a U-shaped groove 205 with an opening direction vertically facing downward is opened on the hanging plate 204. The main cross beam 202 of the climbing frame 2 is hung on the anchoring end of the high-strength bolt 802 through the U-shaped groove 205.

[0040] In the present technical solution, a hanging plate 204 with a U-shaped groove 205 is welded at the end of the main cross beam 202 of the climbing frame 2, which can better guide the climbing frame 2 to be installed on the high-strength bolts 802.

[0041] In another technical solution, the sliding system includes a plurality of climbing heads 5 spaced apart along the height direction of the cast object 3, the climbing head includes a base 501, which is anchored to the cast concrete section through an anchor 2 7, the anchor 2 7 includes an embedded part 801 and a high-strength bolt 802 of the same structure as the anchor 1 6, an anchor plate 8 is installed at the anchoring end of the high-strength bolt 802, the anchor plate 8 is arranged against the surface of the concrete, the base 501 is installed on the anchor plate 8, and two limit plates 502 are spaced apart along the height direction of the base 501 on opposite sides of the base 501, and a clamping sleeve 503 is movably connected between the two limit plates 502.

[0042] In this technical solution, if Figure 2 , Figure 4As shown, the climbing head 5 is installed in the concrete poured section through the base 501, and two limit plates 502 are provided on the opposite sides of the base 501. Two pin holes are provided on any limit plate 502, and the clamping sleeve 503 is fixedly installed between the two limit plates 502 through two pins 504, and the climbing rail 201 is located between the two clamping sleeves 503; during the lifting operation, one of the pins 504 is removed, and the clamping sleeve 503 is rotated so that the two clamping sleeves 503 are in a state of being away from each other, that is, the clamping sleeve 503 does not contact the climbing rail 201, and the hydraulic cylinder 4 is driven to lift the climbing frame 2. When the climbing frame 2 climbs to the right position, the clamping sleeve 503 is rotated so that the two clamping sleeves 503 are close to each other until the climbing rail 201 is clamped between the two clamping sleeves 503, and the removed pin 504 is installed so that the two clamping sleeves 503 are in a state of clamping the climbing rail 201, thereby ensuring the stability of the hydraulic self-climbing formwork system after climbing; the anchor 27 side On the one hand, it is used to install the climbing head 5 to the poured concrete section, and on the other hand, it is used to prevent the static load during the construction process from causing fatigue failure of the high-strength bolts 802 of the anchor 6, which brings the risk of falling, so as to realize the mechanical anti-fall function; during the concrete pouring construction, the deadweight, construction load, wind load, concrete side pressure, etc. of the hydraulic self-climbing formwork system mainly act on the high-strength bolts 802 at the anchor 6 through the hanging plate 204 at the end of the main beam 202. Under normal circumstances, the high-strength bolts 802 at the anchor 27 are not subject to various loads during the construction process, but when the high-strength bolts 802 at the anchor 6 produce fatigue failure, the entire hydraulic self-climbing formwork system tends to sink. At this time, the high-strength bolts 802 at the anchor 27 replace the high-strength bolts 802 at the main beam 202, and bear various loads for a short time to ensure that the climbing formwork does not fall. The hydraulic cylinder 4 is installed on the base 501.

[0043] In another technical solution, the climbing rail 201 includes two oppositely arranged channel steels, which are connected as a whole by multiple connecting rods; two tongue plates 505 are arranged side by side at one end of the base 501 close to the climbing rail 201, and any tongue plate 505 is connected to the base 501 through a reset spring.

[0044] The two ends of any connecting rod are fixedly connected to the two channel steels. After the climbing head 5 is installed, the connecting rod is opposite to the climbing head 5. The two ferrules 503 are respectively located on the outsides of the two channel steels. The tongue plate 505 extends into the gap between the two channel steels and contacts with the connecting rod of the corresponding height. During the lifting operation, the hydraulic cylinder 4 lifts the climbing frame 2 upward, and the climbing rail 201 moves upward accordingly. The connecting rod on the climbing rail 201 continuously compresses the tongue plate 505. After climbing into place, the tiger's mouth on the tongue plate 505 contacts with the connecting rod of the corresponding height, that is, the connecting rod is hung at the tiger's mouth of the tongue plate 505, and cooperates with the ferrule 503 to clamp the two channel steels, further realizing the anti-fall function. After each compression, the tongue plate 505 will be reset by the reset spring, and a sound will be heard after each reset, that is, the spacing set by the connecting rod and the number of times the sound occurs during the climbing process can be used by the on-site operator to judge whether the climbing template 1 has climbed into place.

[0045] In another technical solution, the piston rod 401 of the hydraulic cylinder 4 is connected to the climbing rail 201 through a clamp.

[0046] In the present technical solution, the connection and disassembly of the hydraulic cylinder 4 and the climbing rail 201 are realized by driving the clamping claws to clamp and release, which is convenient to use.

[0047] In another technical solution, a cylindrical spacer 203 is provided on the outer periphery of any connecting rod, and two ends of the spacer 203 are rotatably connected to the two channel steels respectively.

[0048] In this technical solution, if Figure 2 As shown, a rotatable spacer sleeve 203 is sleeved on the outer periphery of the connecting rod, which avoids wear on the surface of the connecting rod caused by hard friction between the tongue plate 505 and the connecting rod during the upward movement of the climbing rail 201.

[0050] In this technical solution, if Figure 5 As shown, the roller 903 on the reaction seat 9 abuts against the surface of the poured concrete to ensure that the climbing rail 201 remains in a vertical state. During the lifting operation, the roller 903 rolls on the surface of the poured concrete.

[0051] In another technical solution, the climbing formwork 1 is provided with an anchor 1 6 and an anchor 2 7 .

[0052] In the present technical scheme, bolt holes are opened on the climbing formwork 1. When the climbing formwork 1 is climbed into place, the high-strength bolts 802 are passed through the bolt holes and threadedly connected with the embedded parts 801 to install the anchors 1 6 and 7 on the climbing formwork. The number of anchors 2 7 is selected according to the number of climbing heads 5 to be installed. When pouring concrete, the embedded parts 801 are embedded in the concrete.
