Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction platform and a construction process for building a vault. Background Art

[0002] The steps of arch structure construction are generally waterproofing first, then tying steel bars, then building arch formwork, and finally pouring concrete. The arch construction platform will be used in the construction. The arch construction platform is a temporary or permanent facility used to support and assist the construction of the arch structure.

[0003] In order to facilitate the construction of the vault, the height and width of the existing construction platform can generally be adjusted according to the height and shape of the vault to meet different construction requirements. The platform generally has a reasonable working area to ensure that workers have enough space to operate and facilitate the storage and handling of materials and tools.

[0004] In the construction of the arch, waterproofing is usually done by hanging a waterproof cloth on the arch surface. Since the cross-section of the arch is an arc-shaped structure, it is not easy for the waterproof cloth to fit the arch surface. The existing way of hanging the waterproof cloth is usually to use the support poles on the construction platform to prop up the waterproof cloth, and then the workers stand on the construction platform to manually hang the cloth. In the process of tying the steel bar frame and building the arch formwork, the construction platform mainly plays the role of moving the steel bars and formwork, and serves as a carrier for workers to stand at high places to tie the steel bars and build the arch formwork. Therefore, the effect of the construction platform in hanging waterproof cloth, tying the steel bar frame and building the arch formwork is not strong. To this end, we propose a construction platform and construction process for arch construction. Summary of the invention

[0013] A construction process for a construction platform for arch construction comprises the following steps: S1, laying a waterproof cloth outside a plurality of pressure rollers, using a first hydraulic assembly to lift a lifting rod and a positioning frame to a construction position, and then using a second hydraulic assembly to drive a connecting frame and pressure rollers so that the pressure rollers press the waterproof cloth onto the section to be constructed; S2. Use each driving motor to drive the corresponding rotating shaft to rotate. The rotating shaft drives the limiting shaft to rotate through the structure of the fixed sleeve and the limiting tube. The rotating shaft drives the second hydraulic component to rotate at the same time. The limiting shaft and the second hydraulic component drive the connecting frame and the pressure roller to rotate synchronously. The pressure sensor detects the pressure value at the connection between the output end of the second hydraulic component and the connecting frame. The pressure value is adjusted within a preset range through the expansion and contraction of the output end of the second hydraulic component. S3. After the waterproof cloth is installed on the section, the positioning frame and the pressure roller are reset, and the distance between the I-frames on both sides of the positioning frame is adjusted by using the third hydraulic assembly. A top frame of a suitable size is clamped above the I-frame, and a corresponding top plate is clamped above the top frame. The top steel bar frame is tied above the top plate. After the top steel bar frame is tied, the first hydraulic assembly is used to lift the lifting rod and the positioning frame to the construction position, and then the steel bar frame is tied on the side. S4. After the side reinforcement frame is tied, the arch frame formwork is installed through the connecting rod, and then the angle frame and angle plate are installed. After all the arch formwork components are installed, the formwork support frame is used for reinforcement, and then the concrete is poured; S5. After the concrete construction is completed, in the demolding stage, the positioning frame is reset. During the reset process, the arch formwork is lowered at the same time, and the construction platform is transferred to the next construction section. The section is continued to support the arch formwork and arch corner formwork by the formwork support frame to carry out the next section of construction; S6. Repeat the above steps S1 to S3 for the next construction section.

In the second construction section, first fix the arch frame formwork and arch corner formwork, then lift the arch top formwork into place, and use the formwork support frame to reinforce it before carrying out concrete construction.

[0014] Preferably, in S3, in each construction stage, the fifth hydraulic assembly is used to increase or decrease the extension length of the extension tube according to demand to increase or decrease the overall length of the arch form assembly.

[0015] The present invention has the following beneficial effects: 1. The present invention first ties the steel bar frame on the arch form assembly above the positioning frame, and then uses the lifting assembly to lift the steel bar frame on the arch form assembly above the positioning frame, so as to facilitate the erection of the steel bar frame structure at the top of the section. By using the lifting assembly to lift the arch form assembly and the steel bar frame above the positioning frame to the construction position and then continue to lift it a short distance, it is convenient to stably support the steel bar frame above, thereby solving the risk of the steel bar frame above falling. Then, by tying the steel bar frames on both sides of the platform, the steel bar frames on both sides of the section are used to support the steel bar frame above the section, so that the steel bar frames on both sides of the section play a role of stabilizing support for the steel bar frame above, making the connection between the steel bar frames more firm. This design has higher efficiency and safer binding for the steel bar frames, and saves time and effort. .

[0016] 2. The present invention detects the pressure at the connection between the output end of the second hydraulic component and the connecting frame through a pressure sensor to monitor the pressure of the pressure roller pressing the waterproof cloth on the cross section, and uses the expansion and contraction of the output end of the second hydraulic component to adjust the pressure value of the pressure roller pressing the waterproof cloth on the cross section so that the pressure value is within the threshold range, ensuring that the waterproof cloth is in close contact with the cross section, avoiding excessive pressure on the waterproof cloth by the pressure roller pressing the waterproof cloth on the cross section, resulting in damage to the waterproof cloth, and avoiding insufficient pressure, resulting in loose connection between the waterproof cloth and the cross section. The elongation length of the second hydraulic component can be adjusted to meet the construction platform for different cross sections.

[0017] 3. The present invention uses the third hydraulic component to adjust the spacing between the I-frames on both sides of the construction platform, so as to facilitate the installation of arch formworks of different sizes, so that the platform can meet the construction requirements of different sections. By setting the arch formwork assembly as a structure of an arch formwork, an arch frame formwork and an arch angle formwork, the arch formwork is first installed on the I-frame, and the steel bar frame is tied on the arch formwork. By lifting the arch formwork, the arch formwork plays a supporting role on the arch formwork, which facilitates the installation of the top steel bar frame first. After the steel bar frames on both sides are tied, the arch frame formwork and the arch angle formwork on both sides are installed, so as to facilitate the overall combination and molding of the arch formwork assembly. In order to improve the strength of the arch formwork assembly, the arch formwork assembly combined and molded using the formwork support frame is reinforced.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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. Example:

[0022] See also Figure 1 - Fig. 9 As shown, a construction platform for arch construction includes a moving track 1, a traveling frame 2 and a positioning frame 3 arranged above the moving track 1, the positioning frame 3 is located directly above the traveling frame 2, the traveling frame 2 and the positioning frame 3 are connected by a lifting assembly 4, a rolling assembly 6 for hanging a waterproof cloth 5 is arranged above the positioning frame 3 and on the side of the lifting assembly 4, an arch mold assembly 7 is arranged above the positioning frame 3 and on the side of the lifting assembly 4, and the lifting assembly 4 lifts the arch mold assembly 7 above the positioning frame 3; Based on this device, when this construction platform is working, the rolling assembly 6 is first used to hang the waterproof cloth 5. Then the arch mold assembly 7 is installed above the positioning frame 3, and then the steel bar frame 26 is tied above the arch mold assembly 7. The arch mold assembly 7 and the steel bar frame 26 above the positioning frame 3 are lifted to the construction position by the lifting assembly 4, and then the steel bar frame 26 is tied on both sides of the construction platform. The steel bar frames 26 on both sides support the steel bar frame 26 above the positioning frame 3, and then the arch mold assembly 7 above the positioning frame 3 is lowered to the construction position by the lifting assembly 4. At this time, because the steel bar frames 26 on both sides support the steel bar frame 26 above the positioning frame 3, the steel bar frame 26 above the positioning frame 3 and the arch mold assembly 7 above the positioning frame 3 do not contact each other. In the process of pouring concrete, the problem of the steel bar frame 26 being exposed due to the contact between the steel bar frame 26 and the arch mold assembly 7 is avoided. After all the steel bar frames 26 are tied, the arch mold assemblies 7 on both sides of the construction platform are installed.

[0023] The lifting assembly 4 includes a fixed rod 41 fixedly arranged on both sides above the traveling frame 2, a lifting rod 42 sleeved on the upper end of the fixed rod 41, and a first hydraulic assembly 43 fixedly installed on both sides above the traveling frame 2. The top of the lifting rod 42 is fixedly connected to the positioning frame 3, and the upper output end of the first hydraulic assembly 43 is fixedly connected to the positioning frame 3; the output end of the first hydraulic assembly 43 lifts and lowers the lifting rod 42 by telescoping.

[0024] In this design, by first tying the steel bar frame 26 on the arch form assembly 7 above the positioning frame 3, and then using the lifting assembly 4 to lift the steel bar frame 26 on the arch form assembly 7 above the positioning frame 3, it is convenient to set up the steel bar frame 26 structure at the top of the section. By using the lifting assembly 4 to lift the arch form assembly 7 and the steel bar frame 26 above the positioning frame 3 to the construction position and then continue to lift it for a short distance, it is convenient to stably support the upper steel bar frame 26, and solve the risk of the upper steel bar frame 26 falling. Then, by tying the steel bar frame 26 on both sides of the platform, the steel bar frames 26 on both sides of the section are used to support the steel bar frame 26 above the section, so that the steel bar frames 26 on both sides of the section play a role of stabilizing and supporting the upper steel bar frame 26, making the connection between the steel bar frames 26 more solid, this design has a higher efficiency in tying the steel bar frame 26, a safer tying, and saves time and effort.

[0025] The rolling assembly 6 includes a second hydraulic assembly 61, a power assembly 62 for driving the second hydraulic assembly 61 to rotate, a connecting frame 63 fixedly arranged at the output end of the second hydraulic assembly 61, and a pressure roller 64 movably installed on the inner side of the connecting frame 63. A pressure sensor 8 is arranged at the connection between the output end of the second hydraulic assembly 61 and the connecting frame 63. A mounting frame 9 for mounting the power assembly 62 is fixedly arranged above the positioning frame 3 and on the side of the lifting rod 42. The pressure roller 64 presses the waterproof cloth 5 onto the section to be constructed. During the process of the power assembly 62 driving the second hydraulic assembly 61 to rotate, the connecting frame 63 and the pressure roller 64 are driven to rotate synchronously. During the rotation of the pressure roller 64, the waterproof cloth 5 is rolled onto the section to be constructed.

[0026] In this design, during the rolling process of the waterproof cloth 5, the pressure sensor 8 monitors the pressure of the pressure roller 64 pressing the waterproof cloth 5 on the cross section by detecting the pressure at the connection between the output end of the second hydraulic component 61 and the connecting frame 63. The pressure value of the pressure roller 64 pressing the waterproof cloth 5 on the cross section is set to a threshold range. The output end of the second hydraulic component 61 is extended and retracted to make the pressure value within the threshold range to ensure that the waterproof cloth 5 is in close contact with the cross section, avoiding excessive pressure on the waterproof cloth 5 by the pressure roller 64, resulting in damage to the waterproof cloth 5, and avoiding insufficient pressure, resulting in loose connection between the waterproof cloth 5 and the cross section. The elongated length of the second hydraulic component 61 can be adjusted to meet the construction platform for different cross sections.

[0027] The arch mold assembly 7 includes an arch top mold 71, an arch frame mold 72 and an arch corner mold 73. A third hydraulic assembly 10 is fixedly arranged on both sides of the positioning frame 3. An I-beam 11 for clamping the arch top mold 71 is fixedly arranged at the output end of the third hydraulic assembly 10. A connecting rod 12 for clamping the arch frame mold 72 is arranged on the side of the lifting rod 42. The arch corner mold 73 is clamped between the arch top mold 71 and the arch frame mold 72.

[0028] In this design, the third hydraulic assembly 10 is used to adjust the spacing between the I-shaped frames 11 on both sides of the construction platform, so that the arch formwork 71 of different sizes can be installed conveniently, so that the platform can meet the construction requirements of different sections. By setting the arch formwork assembly 7 as the structure of the arch formwork 71, the arch frame formwork 72 and the arch angle formwork 73, the arch formwork 71 is first installed on the I-shaped frame 11, and the steel bar frame 26 is tied on the arch formwork 71. By lifting the arch formwork 71, the arch formwork 71 plays a supporting role on the arch formwork 71, which is convenient for first setting up the top steel bar frame 26. After the steel bar frames 26 on both sides are tied, the arch frame formwork 72 and the arch angle formwork 73 on both sides are installed, so that the arch formwork assembly 7 can be combined and formed as a whole. In order to improve the strength of the arch formwork assembly 7, the arch formwork assembly 7 combined and formed using the formwork support frame is reinforced. After the pouring is completed, the arch formwork 71 is lowered to facilitate the quick disassembly of the combined arch formwork assembly 7.

[0029] This construction platform plays a significant role in waterproofing, tying steel bars 26, and building arch formwork.

[0030] Among them, walking wheel groups 13 are movably arranged on both sides of the bottom of the walking frame 2, and the walking frame 2 moves above the moving track 1 through the walking wheel groups 13. Auxiliary wheels 16 are arranged at the bottom of the traveling end of the walking frame 2, and a rotating platform 14 is fixedly arranged in the middle of the bottom of the walking frame 2, and a fourth hydraulic component 15 is arranged at the bottom of the rotating platform 14.

[0031] In this design, the bottom of the walking wheel group 13 is a roller structure, and the roller rolls on the moving track 1 to facilitate the overall movement of the construction platform. The auxiliary wheel 16 is used to assist the movement of the construction platform and reduce the force on the walking wheel group 13. By lowering the fourth hydraulic component 15, the fourth hydraulic component 15 plays an upward supporting role on the construction platform, so that the walking wheel group 13 leaves the moving track 1. At this time, by rotating the rotating platform 14, the construction platform as a whole is driven to rotate, which can make the platform rotate freely in the main channel, T-junction, and crossroads, so that the platform can be carried out on the track, and then it is convenient for the platform to move to different sections for construction.

[0032] The power assembly 62 includes a rotating shaft 621 movably disposed on the mounting frame 9 , and a driving motor 622 fixedly mounted on a side of the mounting frame 9 , and the driving motor 622 drives the rotating shaft 621 to rotate.

[0033] Based on this device, the driving motor 622 drives the rotating shaft 621 to rotate, thereby driving the second hydraulic component 61 to rotate synchronously, thereby conveniently providing power for the rolling work of the rolling component 6.

[0034] The arch top template 71 includes a top frame 711 mounted on the I-frame 11 and a top plate 712 mounted above the top frame 711 . The arch corner template 73 includes a corner frame 731 mounted on the side of the top frame 711 and a corner plate 732 mounted above the corner frame 731 .

[0035] Based on the present device, the top frame 711 is provided to facilitate the splicing and combination of the top plate 712 on the I-shaped frame 11. The corner frame 731 is provided to facilitate the splicing and combination of the corner plates 732.

[0036] Among them, extension tubes 17 are provided at the two corners of the moving end of the positioning frame 3, and a fifth hydraulic component 18 for adjusting the extension length of the extension tube 17 in the positioning frame 3 is fixedly provided on the inner side of the positioning frame 3, and a bracket 19 for clamping the top frame 711 is fixedly provided at the protruding end of the extension tube 17.

[0037] Based on the present device, the adjustment range of the extension tube 17 is three meters. When the platform as a whole does not move, a vault template 71 within a range of three meters can be installed on the platform.

[0038] Among them, a side seat 24 is fixedly provided on the side of the lifting rod 42, and the number of the side seats 24 and the connecting rod 12 is the same and one-to-one corresponding, and an anti-slip soft cover 25 is fixedly provided inside the side seat 24, and the anti-slip soft cover 25 and the connecting rod 12 have an interference fit, and the connecting rod 12 is inserted into the anti-slip soft cover 25, and a storage plate 20 for placing the steel frame 26 is provided above one end of the connecting rod 12 on the same side and at the same height of the lifting rod 42.

[0039] Based on the device, the anti-skid soft cover 25 and the connecting rod 12 are interference-fitted, so that the connecting rod 12 is fixed in the side seat 24 due to friction. By installing the storage plate 20 on the connecting rod 12 and observing the extended length of the connecting rod 12 on one side of the storage plate 20, it can be seen whether the installed arch formwork 72 is deformed, thereby avoiding irregular concrete pouring.

[0040] The side of the connecting frame 63 is fixedly mounted with a limiting shaft 21 , the middle of the rotating shaft 621 is fixedly mounted with a fixing sleeve 22 , the side of the fixing sleeve 22 is fixedly mounted with a limiting tube 23 , and one end of the limiting shaft 21 is inserted into the inside of the limiting tube 23 .

[0041] Based on this device, the limiting shaft 21 slides inside the limiting tube 23. During the rotation of the rotating shaft 621, the limiting tube 23 drives the connecting frame 63 to rotate synchronously through the limiting shaft 21, thereby reducing the pressure of the output shaft of the second hydraulic component 61 on the cylinder and preventing wear and leakage.

[0042] A construction process for a construction platform for arch construction comprises the following steps: S1, laying the waterproof cloth 5 outside the plurality of pressure rollers 64, using the first hydraulic assembly 43 to lift the lifting rod 42 and the positioning frame 3 to the construction position, and then using the second hydraulic assembly 61 to drive the connecting frame 63 and the pressure rollers 64, so that the pressure rollers 64 press the waterproof cloth 5 onto the section to be constructed; S2. Use each driving motor 622 to drive the corresponding rotating shaft 621 to rotate. The rotating shaft 621 drives the limiting shaft 21 to rotate through the structure of the fixing sleeve 22 and the limiting tube 23. The rotating shaft 621 drives the second hydraulic assembly 61 to rotate at the same time. The limiting shaft 21 and the second hydraulic assembly 61 drive the connecting frame 63 and the pressure roller 64 to rotate synchronously. The pressure sensor 8 detects the pressure value at the connection between the output end of the second hydraulic assembly 61 and the connecting frame 63. The pressure value is adjusted within a preset range through the expansion and contraction of the output end of the second hydraulic assembly 61. S3, after the waterproof cloth 5 is installed on the section, the positioning frame 3 and the pressure roller 64 are reset, and the third hydraulic assembly 10 is used to adjust the distance between the I-shaped frames 11 on both sides of the positioning frame 3, and a top frame 711 of a suitable size is clamped above the I-shaped frame 11, and a corresponding top plate 712 is clamped above the top frame 711, and the top steel bar frame 26 is tied above the top plate 712.

After the arch formwork assembly 7 is fully installed, the formwork support frame is first used for reinforcement, and then concrete is poured; S5, after the concrete construction is completed, in the demoulding stage, the positioning frame 3 is reset, and the arch template 71 is lowered at the same time during the reset process, and the construction platform is transferred to the next construction section. The section is continued to support the arch template 72 and the arch corner template 73 by the template support frame to carry out the next construction; S6. Repeat the above steps S1 to S3 for the next construction section. After the side reinforcement frame 26 is tied for the next construction section, the construction platform returns to the first construction section, and the arch frame formwork 72 and the arch corner formwork 73 are hoisted back to the second construction section.
