Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, and in particular to an integrated device for a retractable and split formwork frame. Background Art

[0002] In the construction of high piers and high towers in my country, slipforms are widely used because of their fast construction speed, small site occupation, strong structural integrity, good seismic performance, guaranteed safe operation, and significant environmental and economic benefits.

[0003] Slipform construction is a construction process in which steel pipes (called support rods) are pre-embedded in the concrete structure of the pier body, and all construction loads of the sliding formwork are transferred to the support rods using jacks and lifting frames. After the concrete has initially set, the entire device is slid upward along the support rods through its own hydraulic lifting system. After the formwork is positioned, concrete is poured, and the cycle is repeated continuously.

[0004] However, slipform construction is only suitable for the construction of high piers with uniform cross-sections and cannot meet the requirements of construction with non-uniform cross-sections. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated device for a contracting and diverging formwork frame to solve the technical problem that the existing high piers and high towers with non-uniform cross-sections are difficult to construct.

[0006] The present invention provides a shrinking mold frame integrated device, comprising two non-scaling side enclosures and two shrinking side enclosures;

[0007] The two non-retracting side enclosures and the two retracting side enclosures are arranged opposite to each other, and both ends of the retracting side enclosures can extend into the non-retracting side enclosures;

[0014] At least two lifting frames are arranged on the non-retracting side enclosure and the retracting side enclosure.

[0015] Furthermore, it also includes a template system, the template system includes a plurality of templates, and the plurality of templates form a mold for pouring;

[0016] The template is provided with a hook connected to the lifting frame, so that the template system and the lifting frame can be lifted synchronously;

[0017] The template is also provided with a template screw, and the template screw is used to connect the template with the non-retracting side enclosure ring or the retracting side enclosure ring corresponding to the template.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 3 As shown, a shrinking mold frame integrated device provided by the present invention includes two non-shrunk side enclosures 100 and two shrinking side enclosures 200;

[0036] The two non-retracting side enclosures 100 and the two retracting side enclosures 200 are respectively arranged opposite to each other, and both ends of the retracting side enclosures 200 can extend into the non-retracting side enclosures 100;

[0037] The retracting side enclosure 200 can reciprocate in the length direction of the non-retracting side enclosure 100;

[0038] A traction fixture is disposed in the non-retracting side enclosure 100 , and the traction fixture is used to fix the position of the retracting side enclosure 200 on the non-retracting side enclosure 100 .

[0039] In some embodiments, taking a high pier with a one-way variable cross-section as an example, two non-tapering side enclosures 100 and two tapering side enclosures 200 form a mold frame, the positions of the two non-tapering side enclosures 100 are relatively fixed, and the two ends of the tapering side enclosures 200 respectively extend into the non-tapering side enclosures 100, and the tapering side enclosures 200 can move on the non-tapering side enclosures 100, so that the distance between the two tapering side enclosures 200 can be adjusted.

[0040] After the distance between the two converging side enclosures 200 is fixed, the distance between the two converging side enclosures 200 is fixed by pulling the fixing member, and the positions of the converging side enclosure 200 and the non-converging side enclosure 100 are fixed at the same time.

[0041] Since the high pier has an inclined surface, the tapered side enclosure 200 is located at the high pier with the inclined surface, and the contact surface between the tapered side enclosure 200 and the high pier is an inclined surface.

[0042] like Figure 5 As shown, based on the above embodiment, further, the traction fixing member is an anchor rod 300, and the anchor rod 300 includes a fixing rod 301 and a threaded rod 302, and one threaded rod 302 is provided at both ends of the fixing rod 301;

[0043] The fixing rod 301 is fixed on the non-retracting side enclosure 100 , the threaded rod 302 is connected to the retracting side enclosure 200 , and the retracting side enclosure 200 can be moved and fixed along the threaded rod 302 .

[0044] In some embodiments, the traction fixing member selects an anchor rod 300, and the fixing rod 301 is fixed on the non-retracting side enclosure 100. Threaded rods 302 are fixed at both ends of the fixing rod 301. The retracting side enclosure 200 can move along the threaded rod 302. When it needs to be fixed, the position of the retracting side enclosure 200 is generally fixed by a fixed nut on the threaded rod 302.

[0045] Based on the above embodiment, further, a lifting system is included, and the lifting system includes a lifting frame 600, a plurality of supporting steel pipes 900 and a plurality of transverse connecting rods 110;

[0046] The support steel pipe 900 is fixed to the high pier, and the support steel pipe 900 passes through the lifting frame 600. A hydraulic lifting system is provided on the lifting frame 600, and the hydraulic lifting system is used to move the lifting frame 600 along the support steel pipe 900; the transverse connecting rod 110 is used to transversely connect the support steel pipe 900;

[0047] At least two lifting frames 600 are disposed on the non-retracting side enclosure 100 and the retracting side enclosure 200 .

[0048] The lifting system is used to raise the entire integrated shrinking and spreading formwork device as a whole, so as to continuously cast high piers and high towers and realize the self-climbing of the integrated shrinking and spreading formwork device.

[0049] Steel pipes, namely supporting steel pipes 900, are embedded in the concrete structure of the pier body of the high pier; the lifting frame 600 is connected to the supporting steel pipe 900, and the hydraulic lifting system includes a through-core hydraulic jack, which provides power for the lifting frame 600 to lift along the supporting steel pipe 900. Generally, the jack can be a QYD-100 type through-type jack, with a designed lifting capacity of 100KN, a working lifting capacity of 50KN, a stroke of 35cm, and a self-locking device. The jack works cyclically through two internal toothed snap rings and crawls upward along the supporting steel pipe 900.

[0050] In order to ensure the stability of the supporting steel pipes 900, transverse connecting rods 110 are connected between the supporting steel pipes 900. The transverse connecting rods 110 enable multiple supporting steel pipes 900 to form a stable support, thereby meeting the need of the lifting system to make the entire integrated retracting and splitting mold frame device climb.

[0051] like Figure 4 As shown, based on the above embodiment, further, a template system is included, wherein the template system includes a plurality of templates, and the plurality of templates form a mold for casting;

[0052] The template is provided with a hook 130 connected to the lifting frame 600, so that the template system and the lifting frame 600 can be lifted synchronously;

[0053] The template is also provided with a template screw, and the template screw is used to connect the template with the non-retracting side enclosure ring 100 or the retracting side enclosure ring 200 corresponding to the template.

[0054] In some embodiments, the formwork system is used to form a mold for pouring the pier body on the pier body, and concrete is poured on the mold, thereby forming a new pier body on the pier body and increasing the height of the entire pier body.

[0055] It is an existing technology to use a template to form a mold for pouring the pier body. A hook 130 is provided on the template, and the hook 130 is detachably connected to the lifting frame 600. When the height of the template system needs to be increased, the entire template system rises with the lifting frame 600 through the rise of the lifting frame 600.

[0056] A template lead screw is provided on the template, which is connected to the corresponding non-retracting side enclosure 100 or the retracting side enclosure 200. When the distance between the relative templates needs to be adjusted, the position of the template on the template lead screw can be adjusted to give the template a certain adjustment range. Generally, the template can be adjusted 0.5m forward and backward to meet the construction operation requirements and facilitate the mold closing and disassembly of the template system.

[0057] Based on the above embodiment, further, the template includes a panel 140, an I-beam 150 and a back rib 160;

[0058] The panel 140 is provided with the I-beam 150 , the I-beam 150 is connected to the hook 130 , and the back rib 160 is provided on the I-beam 150 .

[0059] In some embodiments, the panel 140 of the template forms a mold for casting high piers, and a plurality of I-beams 150 are arranged on the panel 140. The I-beams 150 are connected to the hooks 130, and the lifting frame 600 is connected to the hooks 130, so that the lifting system also moves the template system up and down during the process of raising the lifting frame 600.

[0060] The back rib 160 provided on the I-beam 150 is used for fixing adjacent formworks. At the same time, the formwork opposite to the formwork is fixed by pulling against the tie rod, thereby increasing the stability of the entire formwork system.

[0061] Based on the above embodiment, further, a working platform 700 is provided on the side of the non-retracting side enclosure 100 and the retracting side enclosure 200 away from the template;

[0062] A decoration platform 800 is provided at the lower ends of the non-retracting side enclosure 100 and the retracting side enclosure 200 .

[0063] Furthermore, a ladder 500 leading to the decoration platform 800 is provided on the non-retractable side enclosure 100 .

[0064] Furthermore, a protection system 400 is provided on the working platform 700 .

[0065] A finishing platform 800 is provided under the working platform 700 . Generally, the finishing platform 800 is divided into two layers. A ladder 500 is provided on the non-retractable side enclosure 100 , and the finishing platform 800 can be entered through the ladder 500 .

[0066] A protection system 400 is provided on the working platform 700 . The protection system 400 generally includes an anti-falling net and a guardrail, etc., to effectively ensure the safety of operators on the working platform 700 .

[0067] Furthermore, two connecting trusses 120 are provided between the two non-retracting side enclosures 100 , and the two retracting side enclosures 200 are located between the two connecting trusses 120 .

[0068] Furthermore, a roller 170 is provided on the bottom contact surface between the retracting side enclosure 200 and the non-retracting side enclosure 100 , and the retracting side enclosure 200 moves on the roller 170 .

[0069] In order to facilitate the movement of the retracting side enclosure 200, a roller 170 is provided on the non-retracting side enclosure 100, and a steel plate contacted by the roller 170 is provided on the retracting side enclosure 200, so that the retracting side enclosure 200 is more convenient to move.

[0070] The shrinking side enclosure 200 of the shrinking and diverging formwork integrated device provided by the present invention can move along the non-shrinking side enclosure 100 to a certain extent. Generally, in the construction of high piers and high towers, the shrinking side enclosure 200 is located on both sides of the fixed-size part of the high piers and high towers, and the non-shrinking side enclosure 100 is located on both sides of the non-fixed-size part of the high piers and high towers. When the cross-section of the high piers and high towers changes, by changing the relative position of the shrinking side enclosure 200 on the non-shrinking side enclosure 100, the shrinking and diverging formwork integrated device can adapt to the casting of the non-uniform-section high piers and high towers, thereby meeting the shrinking requirements of the one-way variable-section high piers and high towers.
