Description

Technical Field

[0001] The utility model relates to the technical field of early dismantling, in particular to a high-rise early dismantling template system. Background Art

[0002] When constructing a building, the floor slab is usually constructed by pouring concrete, and then the floor slab is supported by formwork and supporting devices. In the conventional formwork construction method, the formwork and supporting devices cannot be removed until the strength of the floor slab reaches 100%. Since the formwork cannot be removed until the concrete is completely cured, the formwork and supporting devices occupy a long time, resulting in high costs.

[0003] The early-removal formwork system uses a special structural design to enable the formwork to be removed in advance after pouring concrete, while the support system remains in place and continues to bear the load. The removal conditions are determined by the concrete strength and component span. For example, when the component span is ≤2m, it will be removed when the design concrete strength grade reaches ≥50%. The early-removal formwork system mainly includes formwork, support columns, lifting devices and early-removal heads. The formwork, support columns, lifting devices and early-removal heads are arranged in sequence. When the concrete strength grade is ≥50%, the lifting device must be lowered first, followed by the early-removal head, and then the formwork is taken out. The support columns and other supporting devices continue to support it. Subsequently, it can be removed accordingly according to the concrete strength grade.

[0004] However, there are still the following problems in the use of early dismantling formwork:

[0005] 1. As the lifting device descends, the support for the formwork disappears and the formwork falls directly from the air, causing damage to the formwork, injuring construction workers or damaging the construction site. Especially when the floor is high above the ground, the impact force generated when the formwork under the high-rise floor falls is large, increasing the chance of damage to the formwork, injuring construction workers or damaging the construction site.

[0006] 2. When laying and dismantling the formwork, construction workers are required to work at height, which is time-consuming. In addition, construction workers working at height are prone to safety hazards.

[0007] Therefore, there is an urgent need for a high-rise early-dismantling formwork system so that the formwork will not fall directly when it is removed, and the construction workers do not need to climb high to lay and dismantle the formwork. Utility Model Content

[0051] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] In the description of the present utility model, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when used. It is only for the convenience of describing the utility model and simplifying the description, and does 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 utility model.

[0054] In addition, the terms “first”, “second”, “third”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0055] In addition, the terms "horizontal", "vertical", "overhanging", etc. do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0056] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connection", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0058] It should be understood that in the prior art, when dismantling the early-removal formwork system, the lifting device must first be lowered, followed by the early-removal head, and then the formwork must be taken out, and the support devices such as support columns continue to provide support. Subsequently, the formwork can be dismantled accordingly according to the concrete strength grade. Among them, due to the lowering of the lifting device, the support for the formwork disappears, and the formwork falls directly from the air, thereby causing damage to the formwork, injuring construction workers or damaging the construction site. In addition, when the floors are high, construction workers who lay and remove the formwork need to climb up to operate, which is time-consuming, and construction workers climbing up to work are prone to safety hazards.

[0059] In order to improve the above problems, this embodiment provides a high-rise early-dismantling formwork system, including multiple support units 1, which are arranged continuously in the longitudinal and transverse directions, and the multiple support units 1 are supported on the lower surface of the floor slab 2.

[0060] Among them, Figure 1-Figure 3 As shown, the support unit 1 includes four support columns 100, an early dismantling plate 200 and a plurality of lifting columns 300. In this structure, the four support columns 100 are arranged at intervals, and the four support columns 100 are arranged in a rectangular shape. Specifically, the four support columns 100 are respectively arranged at the four corners of the rectangle, so as to stably support the floor 2. At the same time, the early dismantling plate 200 is transported to the lower surface of the floor 2 by the lifting columns 300, so that the early dismantling plate 200 is supported on the lower surface of the floor 2. At the same time, the supporting function of the lifting columns 300 is used for the early dismantling When the plate 200 is disassembled, the early disassembly plate 200 will not fall directly, and the early disassembly plate 200 can be laid and disassembled through the lifting function of the lifting column 300, thereby avoiding the construction workers from working at heights. Two adjacent support units 1 use two support columns 100 together, thereby reducing the use of support materials and saving costs while ensuring stable support. The lifting column 300 can adopt structures such as an electric push rod, a hydraulic cylinder or a telescopic rod. In this embodiment, the lifting column 300 adopts an electric push rod.

[0061] like Figure 1-Figure 3 As shown, four support columns 100 are supported on the lower surface of the floor 2. Specifically, a top supporting plate 110 is provided at one end of the support column 100 that is in contact with the floor 2. The top supporting plate 110 can be in the shape of a rectangle, a cylinder, etc. In the present embodiment, the top supporting plate 110 is in the shape of a rectangle, so that the contact area between the top supporting plate 110 and the floor 2 is larger, so that the top supporting plate 110 can stably support the floor 2.

[0062] The early removal plate 200 is detachably connected to the lifting column 300, and a plurality of lifting columns 300 are arranged in sequence and at intervals on the lower surface of the early removal plate 200. The early removal plate 200 adopts a rectangular structure, wherein the early removal plate 200 has notches 210 at four corners, and the shape of the notch 210 is adapted to the top supporting plate 110, and the width and length of the notch 210 are both half of the top supporting plate 110. A notch 210 of an early removal plate 200 has two end faces, which are perpendicular to each other and are both fitted with the same top supporting plate 110, thereby allowing a plurality of support units 1 to be continuously arranged.

[0063] Among them, the number of lifting columns 300 can be multiple. In the present embodiment, for the convenience of description, the number of lifting columns 300 is four supporting columns 100. The supporting columns 100 are respectively arranged at the notches 210 at the four corners of the early removal board 200. The surface of the top supporting plate 110 is highly consistent with the surface of the early removal board 200. The lifting column 300 is arranged between two supporting columns 100. Specifically, the lifting column 300 is arranged between two adjacent vertices in the rectangular body surrounded by the four supporting columns 100. The lifting column 300 is arranged at the center of the side of the early removal board 200, so that the four lifting columns 300 exert uniform force on the early removal board 200, thereby stabilizing the support of the early removal board 200.

[0064] In this embodiment, when supporting the floor 2, firstly, two support columns 100 are set on the ground and located on the same side of the rectangular body, and then the early removal board 200 is installed on the four lifting columns 300, and the lifting function of the lifting columns 300 is used to transport the early removal board 200 to fit with the floor 2. At the same time, the end face of the notch 210 of the early removal board 200 fits with the top support plate 110, and then, another support column 100 is set on the other side of the rectangular body, so that the other two top support plates 110 fit with the end faces of the other two notches 210, thereby completing the setting of a support unit 1, and then repeating the above operations in sequence to complete the continuous installation of multiple support units 1.

[0065] In some embodiments, during installation, it is necessary to properly adjust the positions of the top supporting plate 110 and the early disassembly plate 200 so that the top supporting plate 110 and the end surface of the notch 210 of the early disassembly plate 200 are closely fitted. Therefore, in this embodiment, a plurality of pulleys 620 are provided at the bottom of the support column 100 and the lifting column 300. Figure 1 , Fig.17 , Fig.18 and Fig.19 As shown, there are two pulleys 620, which are spaced apart at the bottom ends of the support column 100 and the lifting column 300 in sequence, so that construction workers can easily fit the top support plate 110 and the early removal plate 200 by pushing the support column 100 and the lifting column 300.

[0066] The bottom of the support column 100 and the bottom of the lifting column 300 are both provided with a storage block 600, the storage block 600 has a flip plate 610 that can be flipped inwards, two pulleys 620 are sequentially arranged on the flip plate 610 at intervals, one side of the flip plate 610 and the storage block 600 are rotatably arranged, the other side opposite to the flip plate 610 is provided with a fixing hole 630, and the position where the storage block 600 is connected to the other side of the flip plate 610 is provided with a corresponding fixing hole 630, the pulley 620 is arranged on the side of the flip plate 610 facing the ground, when the pulley 620 needs to be used, the flip plate 610 rotates relative to the storage block 600, and the flip plate 6 The fixing hole 630 on the other side of the flip plate 610 is aligned with the fixing hole 630 on the storage block 600, and then the other side of the flip plate 610 is fixed by bolt connection, so that the position of the pulley 620 is fixed and the pulley 620 can be used normally. After the support column 100 or the lifting column 300 is pushed, the connection between the other side of the flip plate 610 and the storage block 600 is loosened, so that the side of the flip plate 610 rotates inwardly relative to the storage block 600, and the sliding is driven by the flip plate 610 into the storage block 600. At this time, the support column 100 and the lifting column 300 can be normally set on the ground to perform supporting work.

[0067] Among them, the storage block 600 is also provided with a stabilizing hole 640. When the pulley 620 is flipped into the storage block 600 along with the flip plate 610, the fixing hole 630 on the other side of the flip plate 610 is aligned with the stabilizing hole 640. At this time, the pulley 620 can be fixed in the storage block 600 by a threaded connection.

[0068] In some embodiments, in order to form a whole between the top supporting plate 110 and the early disassembly plate 200 so as to withstand a larger force, in this embodiment, Figure 1-Figure 2 As shown, the high-rise early-dismantling formwork system also includes a transmission member 400, which includes a transmission rod 430, a tightening block 410 and a pressing block 420, wherein the transmission rod 430 is arranged in the support column 100, and both ends of the transmission rod 430 are respectively arranged at both ends of the support column 100. Specifically, there is a space for the transmission rod 430 to rotate in the support column 100, and the end of the transmission rod 430 facing away from the ground is arranged in the top support plate 110.

[0069] like Figure 1 , Fig.15 and Fig.16 As shown, the end face of the notch 210 is provided with a tightening opening 211, and the number of the tightening openings 211 is consistent with the number of tightening blocks 410 in the top supporting plate 110 that are in contact with the end face of the notch 210, wherein the tightening blocks 410 are penetrated through the top supporting plate 110 and the notch 210, thereby making the top supporting plate 110 and the early removal plate 200 become a whole.

[0070] Among them, Figure 7-10As shown, a transmission rod 430 is provided at one end of the top supporting plate 110 with a tightening block 410, and the tightening block 410 is penetrated through the top supporting plate 110 and movably connected with one end of the transmission rod 430. Specifically, a sliding groove 440 is provided at one end of the tightening block 410 facing the transmission rod 430, and a connecting port 450 is provided at one end of the transmission rod 430. A connecting rod 480 is provided between the tightening block 410 and the transmission rod 430, wherein the connecting rod 480 is penetrated through the connecting port 450 and both ends are respectively arranged in the sliding groove 440, and the two ends of the connecting rod 480 can be displaced up and down relative to the sliding groove 440, and the connecting rod 480 can rotate relative to the connecting port 450. When the transmission rod 430 rotates, the transmission rod 430 drives the connecting rod 480 to move up and down relative to the sliding groove 440, thereby pushing the tightening block 410 to move left and right relative to the top supporting plate 110, so that one end of the tightening block 410 passes through the top supporting plate 110 and is arranged in the end surface of the notch 210.

[0071] In this embodiment, a pressing block 420 is provided at the other end of the transmission rod 430, and the direction of the pressing block 420 is opposite to that of the tightening block 410. The pressing block 420 is penetrated by the support column 100, and the pressing block 420 is slidably connected with the other end of the transmission rod 430, and the transmission rod 430 can slide up and down relative to the pressing block 420. Specifically, a sliding groove 440 is provided at one end of the pressing block 420 facing the transmission rod 430, and a connecting port 450 is provided at the other end of the transmission rod 430, and a connecting port 450 is provided between the pressing block 420 and the transmission rod 430. The connecting rod 480 is passed through the connecting port 450 and both ends are respectively arranged in the slide groove 440. The two ends of the connecting rod 480 can be displaced up and down relative to the slide groove 440, and the connecting rod 480 can be rotated relative to the connecting port 450. When the construction personnel press the pressing block 420, the pressing block 420 squeezes one end of the transmission rod 430, and the one end of the transmission rod 430 rotates under the action of the connecting rod 480. The connecting rod 480 is displaced up and down relative to the slide groove 440 and rotates relative to the connecting port 450.

[0072] The transmission rod 430 drives the pressing block 410 and the pressing block 420 to move back and forth in the lateral direction.

[0073] In this embodiment, Figure 1-Figure 16 As shown, limit blocks 460 are provided in the slide grooves 440 of the tightening block 410 and the pressing block 420, which are used to limit the displacement of the connecting rod 480, so that when the connecting rod 480 is displaced relative to the slide groove 440 until the tightening block 410 is completely disposed in the end surface of the notch 210, the connecting rod 480 stops displacing.

[0074] Among them, slideways 470 are provided on the inner walls on both sides of the slide groove 440, and the two ends of the connecting rod 480 are respectively arranged on the slideways 470 on the inner walls on both sides of the slide groove 440. The slideways 470 are arranged in the vertical direction so that the connecting rod 480 can slide up and down, and the limit blocks 460 are arranged on the inner walls of the slideways 470. Among them, the number of the limit blocks 460 is two, and the two limit blocks 460 are relatively arranged on the inner walls of the two slideways 470.

[0075] In a more complete solution, such as Figure 1-Figure 2 As shown, elastic members 800 are respectively provided at both ends of the transmission rod 430, and an elastic member 800 is provided at one end of the tightening block 410 arranged in the support column 100. Specifically, an elastic member 800 is provided at one end of the tightening block 410 facing the top supporting plate 110, and an elastic member 800 is provided at one end of the pressing block 420 facing the support column 100. The other end of the elastic member 800 connected to the tightening block 410 is connected to the inner wall of the top supporting plate 110, and the other end of the elastic member 800 connected to the pressing block 420 is connected to the inner wall of the support column 100, so that parts of the tightening block 410 and the pressing block 420 are always located outside the top supporting plate 110 and the support column 100. When the top supporting plate 110 and the early disassembly plate 200 are fitted together, the pressing block 420 is pressed, and the transmission The two ends of the block rotate relative to the center, the elastic member 800 is compressed, and the pressing block 420 and the tightening block 410 are respectively displaced toward the inside of the supporting column 100 and the top supporting plate 110, so that the early removal plate 200 and the top supporting plate 110 are smoothly fitted together. Afterwards, the pressing block 420 is loosened, and the transmission rod 430 rotates in the opposite direction to the previous direction under the action of the elastic member 800, so that the pressing block 420 and the tightening block 410 are displaced toward the outside of the supporting column 100 and the top supporting plate 110, and then one end of the tightening block 410 passes through the top supporting plate 110 and enters the tightening opening 211 of the end face corresponding to the notch 210, so that the top supporting plate 110 and the early removal plate 200 form a whole, thereby stabilizing the support of the floor slab 2, wherein the elastic member 800 can be made of a spring.

[0076] Among them, support plates 700 are sequentially spaced apart in the outer circumference of the support column 100 , and the support plates 700 are supported on the lower surface of the pressing block 420 .

[0077] Among them, when disassembling the early disassembly plate 200, the pressing block 420 is mainly pressed, the transmission rod 430 rotates, the tightening block 410 shrinks into the top supporting plate 110, and then the lifting column 300 is lowered to remove the early disassembly plate 200, so that the support unit 1 supports stably and the disassembly of the early disassembly plate 200 is relatively simple. The construction workers do not need to work at heights, which reduces safety hazards.

[0078] In some embodiments, the number of transmission rods 430 is multiple, such as Figure 1-Figure 6As shown, a plurality of transmission rods 430 are arranged in sequence and at intervals. Specifically, the centers of the plurality of transmission rods 430 are rotatably connected to the support column 100 .

[0079] There are multiple transmission rods 430. For the convenience of description in conjunction with the drawings, in the present embodiment, there are four transmission rods 430. The four transmission rods 430 are arranged in sequence and spaced apart, and two adjacent transmission rods 430 are arranged in a mirror image. Specifically, the tightening blocks 410 of two transmission rods 430 are oriented opposite to the tightening blocks 410 of the other two transmission rods 430, and the two adjacent transmission rods 430 are arranged in opposite directions and rotate in opposite directions.

[0080] Among them, since one supporting plate 110 is fitted with four early removal plates 200 , the tightening blocks 410 of the four transmission rods 430 are respectively penetrated into the tightening openings 211 of the notches 210 of the four early removal plates 200 .
