Description

TECHNICAL FIELD

[0001] The present application relates to construction technology, in particular to a kind of solid square pier segmented one forming construction device. BACKGROUND

[0002] Solid square pier is the most common high bridge support structure, in the prior art, the construction of solid square pier mainly uses traditional turnover mold, climbing formwork or slip form construction technology.Climbing formwork or slip form is mainly applied to the construction of large-section solid square pier.Small-section square pier is difficult to construct in column system beam position due to construction conditions, therefore, small-section square pier of highway engineering generally uses turnover mold construction, and the turnover mold construction technology mainly uses column lengthening on-site binding installation technology during steel bar construction, which is greatly affected by human factors on the quality control of steel bar protective layer due to limited working environment.At the same time, traditional turnover mold construction formwork has many joints and is prone to misalignment;different layers of concrete are prone to color difference due to large pouring time difference.

[0003] For example, the patent application with the application number CN201210006054.X and the publication number 2012.07.11, named "high pier turnover mold construction technology", includes the following process steps: pouring the pier column in layers according to the height of the formwork, and self-climbing formwork construction;the turnover mold construction sequence is as follows: after each layer of pier body is poured and completed, the formwork is turned up when the concrete strength is sufficient, the cross beam is installed at the top of the pier body, the formwork is manually lifted by using a chain block, the formwork is fixed and supported firmly after the formwork is in place, then the lower formwork is removed, the formwork is lifted to the next layer height by using a chain block, the formwork is installed, the support legs between the formwork and the pier body are installed, and the next layer of pier column pouring operation is carried out after confirming the stability.

[0004] Obviously, for small-height solid square piers such as ten meters or less and five meters or less, climbing formwork or slip form is large equipment and the equipment is complex, which is a large material for small use and has high construction cost;and for turnover mold, as described above, it is difficult to form once, and the turnover mold is two or three layers of formwork each time, with a height of generally 2-3 meters, so for square piers with a height of only 5-10, at least two times of pouring construction are required, which leads to long construction time.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-7 As shown in the figure, an embodiment of the present invention provides a solid square pier segmented one-time forming construction device, including four sets of template bodies for enclosing the casting cavity of the solid square pier. Each set of template bodies includes multiple sub-templates 1 connected in sequence in the vertical direction. In the horizontal direction, adjacent sub-templates 1 are connected by transverse connectors 2. Each template body is connected to each sub-template 1 by a vertical connector 3. Concrete is poured in segments in the casting cavity to form the solid square pier.

[0032] Specifically, the solid square pier is approximately cuboid in shape, comprising four vertical or substantially vertical surfaces (for ease of description, these two cases are collectively referred to as vertical surfaces in all embodiments of the present invention, and the direction of the corresponding structure is collectively referred to as the vertical direction). Adjacent vertical surfaces are connected by chamfered or rounded corner structures. Each of the four sets of template bodies corresponds to one vertical surface. Due to the high height of the solid square pier, it is difficult to make each template body into a single slab. Therefore, each template body is designed as multiple sub-templates 1 connected sequentially in the vertical direction. The multiple sub-templates 1 are connected sequentially to form a template body, and adjacent template bodies are also connected to form a casting cavity, which is shaped like the solid square pier. Because the height of the formwork body cast in one go is significantly higher than that of flip formwork or slipform construction (the latter two only have the height of 2-3 sub-formworks 1, while this embodiment may have the height of more than five sub-formworks 1), a stronger connection structure is provided. Moreover, these connection structures include horizontal connectors 2 in the horizontal direction and vertical connectors 3 in the vertical direction. For two adjacent sub-formworks 1, the two ends of the horizontal connectors 2 are respectively connected to the two sub-formworks 1. The simplest horizontal connector 2 can be a rod or a bracket. Its connection with the sub-formworks 1 can be a screw connection, a rotating connection, a plug connection, or other existing connection methods. Fixing and limiting can be done by screw connection, pin connection, etc. In this way, the four sub-formworks 1 in the horizontal direction are connected into a frame by multiple horizontal connectors 2, and the strength is significantly greater than that of supporting a single sub-formwork 1. Meanwhile, the corresponding vertical connector 3, which can be a rod or a bracket, is inserted vertically into each of the sub-templates 1. Preferably, each sub-template 1 is provided with a through hole, and the vertical connector 3 is inserted into each through hole. This not only strengthens the structure but also provides positioning. By connecting all the sub-templates 1 into a whole through the horizontal connector 2 and the vertical connector 3, each sub-template 1 is limited by the horizontal and vertical sub-templates 1 in which it is located, resulting in high overall strength and the ability to bear higher weight.

[0033] In this embodiment, segmented one-time molding refers to the use of multiple segmented pouring operations due to the excessive height, while maintaining continuous pouring. Concrete is poured and vibrated in layers, with pouring personnel directing the pump truck to ensure accurate and reasonable placement of the concrete, vibrating simultaneously with pouring. For each layer of concrete, the vibrator is inserted 5-10cm into the next layer. Vibration is continued until the concrete achieves good density, a smooth, slurry-like surface, no further settling, and no air bubbles. After vibration, the next layer is poured and vibrated until the top is reached. This segmented pouring eliminates the need for curing between pours, thus achieving one-time molding and avoiding the drawbacks of slipform and formwork construction where each layer must be cured before the next can be poured.

[0034] The solid square pier segmented one-time forming construction device provided in this embodiment of the invention directly encloses the complete solid square pier casting cavity with multiple template bodies, and casts the entire solid square pier in one go through segmented casting. In order to ensure higher strength of the integrated structure, the horizontal connecting parts 2 and vertical connecting parts 3 are used to limit and strengthen the structure in both the vertical and horizontal directions, so as to completely limit the multiple template bodies to each other.

[0035] In another embodiment of the present invention, preferably, the template 1 includes a straight section 1.1 located in the middle, the straight section 1.1 corresponding to the vertical surface of the solid square pier, and a mating section 1.2 is provided at each end of the straight section 1.1. The mating section 1.2 is an arc-shaped section or a sloping section, and the chamfered surface or rounded corner surface between the two vertical surfaces corresponding to the mating section 1.2. In the horizontal direction, two adjacent template pieces 1 are connected to each other through the mating section 1.2.

[0036] In another embodiment of the present invention, preferably, the template 1 is provided with a first groove and a first extension on opposite sides. The shape of the first extension matches the shape of the first groove, such as both being cuboid. Thus, in the horizontal direction, when two adjacent templates 1 are connected, the first extension is embedded in the first groove to connect the two templates 1. In this way, the two templates 1 are not simply butted together. The cooperation between the first extension and the first groove provides a certain limit between the two templates 1 and improves the sealing strength.

[0037] In another embodiment of the present invention, preferably, a second groove is provided at the top of the template 1, and a second extension 1.3 is provided at the bottom of the template 1. The shape of the second extension 1.3 is adapted to the shape of the second groove, such as both being cuboid. Thus, in the vertical direction, for two vertically adjacent templates 1, the second extension 1.3 is embedded in the second groove so that the inner wall surface of the casting cavity is vertically flat. Thus, the two templates 1 are not simply joined together. The cooperation between the second extension 1.3 and the second groove provides a certain limit between the two templates 1 and improves the sealing strength.

[0038] In another embodiment of the present invention, the transverse connecting member 2 includes a transverse connecting rod, both ends of which are limited and connected to a template 1. At least one end of the transverse connecting rod is limited and connected by a nut 4. In one optional embodiment, one end of the transverse connecting rod is rotatably connected to one of the templates 1 via a rotating shaft, and the other end of the transverse connecting rod passes through a through hole in another template 1. This end is provided with a threaded section, and a nut 4 is screwed onto the threaded section. The other end is limited by the contact between the nut 4 and the template 1. Thus, the two ends are limited by the rotating shaft and the nut 4 respectively, and the rotation of the nut 4 achieves fastening, which can provide a great fastening force. In another optional embodiment, both ends of the transverse connecting rod are threaded sections, and both ends are fastened by the nut 4.

[0039] In another embodiment of the present invention, the positional relationship between the transverse connecting rod and the sub-template 1 is configured such that the middle part of the transverse connecting rod abuts against the connection part of the two mating sections 1.2. In the prior art, the connection part of the two sub-templates 1 either has no reinforcing structure or is provided with a dedicated reinforcing structure. In this embodiment, by adjusting the position, without adding any structure, the middle part of the transverse connecting rod is used to reinforce the connection part of the two sub-templates 1.

[0040] In this embodiment, the horizontal connecting rods can independently limit the horizontal movement of each template 1. This results in the connecting rods bearing immense supporting force, leading to extremely high contact force between the nut 4 and the template 1, making demolding very difficult and requiring long levers. Although the operating procedures explicitly prohibit the use of a sledgehammer to strike the template 1 and other accessories, in practice, when the nut 4 is difficult to remove, occasional loosening by hammering still occurs. Therefore, a further improvement includes a stress-relieving bearing 5, which is a tapered roller bearing and a thrust ball bearing. The tapered roller bearing and thrust ball bearing are chosen here because these two types of bearings can withstand extremely high axial pressure. Correspondingly, other bearings that can withstand extremely high axial pressure can also be used as relief bearings 5. The relief bearing 5 is movably sleeved on the transverse connecting rod. The nut 4, the relief bearing 5, and the dividing template 1 abut against each other in sequence. That is, the relief bearing 5 is sandwiched between the nut 4 and the dividing template 1. In this way, the huge frictional force between the nut 4 and the dividing template 1 is at least partially replaced by the rolling force between the rollers or rolling elements of the relief bearing 5 and the inner and outer rings, which greatly reduces the difficulty of disassembly.

[0041] More preferably, the inner ring of the unloading bearing 5 abuts against the dividing template 1, and the outer ring of the unloading bearing 5 abuts against the nut 4. The radial dimension of the nut 4 is the same as or substantially the same as that of the outer ring of the unloading bearing 5. In this way, the nut 4 only abuts against the outer ring of the unloading bearing 5, while the dividing template 1 has an annular abutment part that is substantially the same as the radial dimension of the inner ring of the unloading bearing 5. The annular abutment part abuts against the inner ring of the unloading bearing 5. With this arrangement, the abutment force of the nut 4 is completely replaced by rolling force.

[0042] In another embodiment of the present invention, a long strip-shaped linkage limiting member 6 is also included. The linkage limiting member 6 abuts against the outer wall surface of the template 1. Each end of the linkage limiting member 6 is connected to a transverse connecting rod. Preferably, the linkage limiting member 6 is a rod or plate in the middle, and a connecting hole is provided at each end. The connecting hole is sleeved on the transverse connecting rod. Most preferably, the linkage limiting member 6 is a rectangular frame. The middle of the rectangular frame abuts against the outer wall of the template 1, and each end of the rectangular frame is sleeved with a transverse connecting rod. In the aforementioned embodiments, the horizontal and vertical pressures are completely borne by the template 1 itself, and the pressure transmission of the two transverse connecting members 2 depends entirely on the template 1. The template 1 itself has a huge frictional force with the solid square block. The linkage limiting member 6 brings two effects: firstly, it completely limits the horizontal movement of the template 1 to prevent local deformation; secondly, the four transverse connecting members 2 are completely connected into one unit by the four linkage limiting members 6, so that the pressure is borne relatively evenly without being limited by the frictional force of the template 1.

[0043] In this embodiment, the length of the linkage limiting member 6 may vary slightly each time it is used. Preferably, the linkage limiting member 6 consists of two parts connected by a turnbuckle, so that the length of the linkage limiting member 6 can be adjusted by the turnbuckle.

[0044] In another embodiment of the present invention, the vertical connector 3 includes a plurality of vertical rods arranged in parallel, each of the vertical rods passing through each of the sub-templates 1, and the plurality of vertical rods providing multi-line support on each sub-template 1.

[0045] Furthermore, the vertical rod is located inside the linkage limiting member 6, and the linkage limiting member 6 applies pressure to the vertical rod. That is, the template 1, the vertical rod, and the linkage limiting member 6 abut against each other in sequence. The advantage of this is that the horizontal pressure and the vertical pressure are directly connected to achieve comprehensive limiting.

[0046] Since the vertical rod runs through multiple template 1s from top to bottom and is quite tall, disassembly requires pulling the entire vertical rod upwards, which is inconvenient. Furthermore, the vertical rod consists of multiple segments that are plugged or screwed together, with each segment corresponding to one or more template 1s, which facilitates installation and disassembly.

[0047] In a further embodiment, one end of the sub-rod has a first enlarged section 3.1, the radial dimension of which is larger than the radial dimension of the sub-rod. A threaded post is provided on the first enlarged section 3.1, and the radial cross-section of the enlarged section is elliptical, eccentric, or cam-shaped. The reason for the elliptical, eccentric, or cam-shaped shape is that the distance from each point on the edge of the enlarged section to the central axis of the sub-rod is different. Meanwhile, the other end of the sub-rod has a second enlarged section 3.2, the radial dimension of which is larger than the radial dimension of the sub-rod. A threaded hole is provided on the second enlarged section 3.2. The second enlarged portion increases the strength of the connection position. When the two sub-rods are joined together, the threaded hole... The connecting post is screwed into the screw hole. In this embodiment, the outer wall of the template 1 has a protrusion 1.4. The linkage limiting member 6 is limited in the protrusion 1.4. The two ends of the transverse connecting rod are limited on the protrusion 1.4. At this time, the connection area between the screw post and the screw hole is arranged in the area of ​​the protrusion 1.4, and the first expansion section 3.1 corresponds to the linkage limiting member 6. During the initial installation process, the sub-rod body is not completely tightened. After the assembly is completed, the sub-rod body is tightened again so that the outer wall of the first expansion section 3.1 tightly abuts against the linkage limiting member 6. This ensures the tight abutment between the vertical rod and the linkage limiting member 6, eliminating possible errors caused by thermal expansion and contraction and use during each installation.

[0048] Furthermore, vertical grooves are arranged side by side on the outer wall of the area connecting the first enlarged section 3.1 on the sub-rod body, and a hanging block 7 is also included. The hanging block 7 is inverted L-shaped. The horizontal section of the hanging block 7 is suspended from the hanging part provided on the outer wall of the sub-template 1, like a ring suspended from a protruding column. The vertical section of the hanging block 7 is located between the vertical rod and the outer wall of the sub-template 1 and the sub-rod body, and the shape of the vertical section is consistent with the shape of the vertical groove, similar to a spline fit structure. The purpose of this is to cooperate with the tightening of the sub-rod body so that the outer wall of the first enlarged section 3.1 tightly abuts against the linkage limiting member 6, so that the screw post is unlikely to be tightly screwed into the screw hole. After the sub-rod body is tightened, the hanging block 7 is inserted to limit the sub-rod body and prevent it from rotating on its own. Since the hanging block 7 is located on the upward stroke of the second expansion part of the lower sub-rod, this structure also brings an additional effect: if the upper sub-formwork 1 is not disassembled, the lower sub-formwork 1 cannot be disassembled. This forcibly limits the disassembly sequence of the sub-formwork 1, thus avoiding the situation where on-site construction workers disassemble the loose formwork first when they encounter something difficult to disassemble, and forcing on-site construction workers to disassemble in sequence.

[0049] In another preferred embodiment of the present invention, the device further includes a cable-stayed beam, one end of which is connected to the template body and the other end is connected to the ground foundation. The cable-stayed beam is used to prevent the risk of the solid square pier segmented one-time forming construction device from tilting or tipping over.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
