Description

Technical Field

[0002] An urban integrated pipe gallery refers to a public pipeline tunnel built underground in a city, where two or more municipal pipelines such as electricity, communications, gas, water supply, heat, and drainage are laid in a centralized manner, and unified planning, design, construction, and maintenance are implemented. Underground pipe galleries are also known as "common pipelines and integrated pipe trenches" in my country. In the pouring construction of underground integrated pipe galleries, formwork trolleys are widely used construction equipment. The pouring efficiency of using formwork trolleys is 30% higher than that of traditional formwork, and the speed of mold loading and demolding is 2 to 3 times faster, and the manpower used is 1 / 5 of the past.

[0003] The formwork trolley system includes an inner formwork and an outer formwork, which constitute the main body of the model cavity. During construction, the inner formwork is moved by the trolley. When the inner formwork is moved into place, the outer formwork is installed at the corresponding position. After pouring is completed, the outer formwork is removed, the inner formwork is moved to the next construction section, and then the outer formwork is installed.

[0004] However, this construction method also has some obvious problems. First, the outer formwork needs to be repeatedly installed and disassembled as the inner formwork moves, which not only increases the complexity of construction, but also consumes a lot of time and manpower. Secondly, when removing the outer formwork, it is often difficult to demould smoothly because the model surface of the formwork is closely connected to the poured wall, which not only affects the construction progress, but may also cause damage to the formwork.

[0005] The above shortcomings need to be improved. Utility Model Content

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] like Figure 2 and Figure 3 As shown, an outer formwork for the construction of an integrated pipe corridor described in one embodiment of the utility model includes a formwork body 1, a first running mechanism 2 is arranged above the formwork body 1, and a second running mechanism 3 is arranged below the formwork body 1, the first running mechanism 2 and the second running mechanism 3 are used to move the formwork body 1, and a demoulding mechanism 4 is arranged on the second running mechanism 3, and the demoulding mechanism 4 is used to separate the formwork body 1 from the cast wall.

[0032] In the construction preparation stage, when the first section is constructed, the outer formwork is installed at the corresponding position. When other sections are constructed, the first running mechanism 2 and the second running mechanism 3 work together to smoothly move the formwork body 1 to the designated pouring position. When the formwork body 1 reaches the predetermined position, it is firmly fixed there to provide a stable working environment for the subsequent pouring operation.

[0033] After pouring is completed, the demoulding stage begins. At this time, the demoulding mechanism 4 acts on the connection between the template body 1 and the poured wall to separate the template body 1 from the poured wall, which avoids the tedious manual disassembly in the traditional method and greatly reduces the demoulding time.

[0034] After demoulding is completed, the formwork body 1 is quickly moved to the next construction section again through the first running mechanism 2 and the second running mechanism 3, ready to start a new round of pouring operations. During the whole process, the movement and demoulding process of the outer formwork is simplified, which greatly improves the construction efficiency and reduces the labor cost.

[0035] The outer template shortens the movement and demoulding time of the template body 1 through the walking structure and demoulding mechanism 4, making the entire construction process more efficient. The rapid and accurate movement and demoulding of the template also helps to ensure the quality and consistency of the poured wall and improve the construction accuracy. In addition, it not only improves the construction efficiency, but also reduces the labor intensity of workers, reduces the use of workers, and saves labor costs.

[0036] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the first running mechanism 2 includes a connecting frame 201 connected to the top of the template body 1, a roller bracket 207 is provided at the first end of the connecting frame 201, two clamping rollers 213 are provided on the roller bracket 207, the clamping rollers 213 are vertically arranged, a first translation guide rail 214 is arranged between the two clamping rollers 213, and a connecting seat 215 is arranged at the bottom of the first translation guide rail 214. An embedded rod 216 is arranged at the bottom of the connecting seat 215, and the embedded rod 216 is connected to the steel cage in the model cavity, and the embedded rod 216 and the steel cage can be connected by welding or binding.

[0037] In the construction preparation stage, firstly, a roller bracket 207 is installed at the first end of the connecting frame 201, and two clamping rollers 213 are arranged on the roller bracket 207, and the two clamping rollers 213 are arranged vertically, and then the connecting frame 201 is connected to the top of the template body 1. A first translation guide rail 214 is arranged between the clamping rollers 213, and the first translation guide rail 214 provides a precise guide for the movement of the template body 1. A connecting seat 215 is arranged at the bottom of the first translation guide rail 214. Before pouring, the embedded rod 216 at the bottom of the connecting seat 215 is connected to the steel cage in the model cavity. The connection between the embedded rod 216 and the steel cage can be achieved by welding or binding. The specific method is selected according to the actual situation on site and the engineering requirements. After the pouring is completed, the embedded rod 216 is stably connected to the solidified concrete to ensure the stability of the first translation guide rail 214, thereby ensuring that the template body 1 can move stably.

[0038] During movement, the outer template can be moved by the first running mechanism 2. At this time, the two clamping rollers 213 are clamped on both sides of the first translation guide rail 214, and move forward steadily along the first translation guide rail 214, driving the template body 1 to move to the next casting position.

[0039] In this embodiment, the first running mechanism 2 improves the stability of the template body 1 during movement. The coordinated use of the clamping roller 213 and the first translation guide rail 214 ensures the stability and accuracy of the template movement, and effectively reduces the shaking and deviation of the template body 1 during movement.

[0040] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the roller bracket 207 includes a mounting frame 208 movably connected to the connecting frame 201, a first adjustment hole is provided on the connecting frame 201, and a second adjustment hole is provided on the mounting frame 208. The first adjustment hole or the second adjustment hole is a waist-shaped hole, and adjustment fasteners are provided through the first adjustment hole and the second adjustment hole. The mounting frame 208 includes a cross bar 209 and a vertical bar 210 provided at both ends of the bottom of the cross bar 209, and a roller seat 211 for mounting a clamping roller 213 is provided on the opposite side of the two vertical bars 210. The roller seat 211 and the vertical bar 210 are connected by bolts, and a spring 212 is provided between the roller seat 211 and the vertical bar 210. The spring 212 is used to push the roller seat 211 so that the clamping roller 213 maintains contact with the first translation guide rail 214.

[0041] During construction, first, the mounting frame 208 of the roller bracket 207 is movably connected to the connecting frame 201, so that the roller bracket 207 can be adjusted according to actual needs, which enhances the flexibility and convenience of construction. During the connection process, the first adjustment hole and the second adjustment hole are used for precise alignment, and the second adjustment hole is a waist-shaped hole to adapt to different installation positions. Then, the adjustment fastener is passed through the first adjustment hole and the second adjustment hole, and the fastening action of the fastener ensures the stable connection between the mounting frame 208 and the connecting frame 201. Subsequently, the clamping roller 213 is installed on the roller seat 211 through the rotating shaft, and the roller seat 211 is connected to the vertical rod 210 by bolts. A spring 212 is arranged on the bolt outer sleeve between the roller seat 211 and the vertical rod 210, and the spring 212 pushes the roller seat 211, so that the clamping roller 213 always keeps in contact with the first translation guide rail 214, ensuring the stability and reliability of the clamping roller 213 during the movement. When the installation work is completed, the outer template can be moved by the first running mechanism 2.

[0042] In this embodiment, the spring 212 on the roller bracket 207 enables the clamping roller 213 to maintain stable contact with the first translation guide rail 214, preventing the roller from detaching from the guide rail due to shaking, thereby improving the stability and accuracy of the outer template during movement.

[0043] like Figure 4 and Figure 5 As shown, in a preferred embodiment, a connecting sleeve 202 is provided at the second end of the connecting frame 201, a fixing rod 204 is provided on the template body 1, the connecting sleeve 202 is sleeved on the fixing rod 204, a first limiting block 205 is provided on the fixing rod 204 below the connecting sleeve 202, a first limiting hole is provided on the first limiting block 205, a second limiting block 203 is provided on the connecting sleeve 202, a second limiting hole is provided on the second limiting block 203, and limiting fasteners 206 are provided in the first limiting hole and the second limiting hole.

[0044] During installation, firstly, a first limiting hole is opened on the first limiting block 205 to provide accurate positioning for subsequent connection. Then, the first limiting block 205 is installed on the outer side of the fixed rod 204, and the first limiting block 205 is fixed on the fixed rod 204 by welding to ensure the stability of its connection. Then, according to the structure and force requirements of the template body 1, the installation rod is fixed at an appropriate position, and the connection between the installation rod and the template body 1 is bolted or welded to ensure that the connection between the installation rod and the template body 1 is firm and reliable. Subsequently, the second end of the connecting frame 201 is aligned with the fixed rod 204, and the connecting sleeve 202 is sleeved on the fixed rod 204, and the connecting frame 201 can rotate freely around the fixed rod 204. The second limiting block 203 is welded on the connecting sleeve 202, and a second limiting hole is set on the second limiting block 203. The size and position of the second limiting hole match the first limiting hole to ensure that the subsequent limiting fastener 206 can be smoothly inserted and play a limiting role.

[0045] During pouring, the connecting frame 201 is away from the pouring area to prevent the concrete slurry from adhering to the connecting frame 201, so as to ensure that the connecting frame 201 can rotate normally. After pouring, the connecting frame 201 is rotated so that the clamping roller 213 moves to the top of the first translation guide rail 214, and moves downward to clamp the clamping roller 213 to both sides of the first translation guide rail 214. At this time, the first limiting hole is aligned with the second limiting hole, and the limiting fastener 206 is inserted into the first limiting hole and the second limiting hole to limit the relative position of the connecting frame 201 and the fixing rod 204. The limiting fastener 206 can be a limiting bolt or a limiting pin. The selection of the limiting fastener 206 is determined according to actual needs and the construction environment to ensure that it has sufficient strength to withstand various loads generated by the template during movement.

[0046] In this embodiment, by setting the connecting sleeve 202, the fixing rod 204 and the limiting structure, the connection between the connecting frame 201 and the template body 1 becomes very stable, which can ensure the stability of the template body 1 during movement and reduce construction problems caused by loose connections. The connecting sleeve 202 and the fixing rod 204 make the connection process simple and fast. The construction personnel only need to put the connecting sleeve 202 on the fixing rod 204 and fix it with the limiting fastener 206. The installation steps are simple. Since the cooperation between the connecting sleeve 202 and the fixing rod 204 has a certain degree of adjustability, the position of the connecting frame 201 can be appropriately adjusted according to actual needs. The stable connection structure not only ensures the stability of the template, but also improves the safety of construction.

[0047] like Figure 6 and Figure 7As shown, in a preferred embodiment, the second running mechanism 3 includes a second translation guide rail 301, and a plurality of caster brackets 302 are arranged on the second translation guide rail 301. The caster brackets 302 are rotatably connected with casters 303, and the outer circumferential surface of the casters 303 is provided with a V-shaped groove, and a V-shaped track 304 matching the V-shaped groove is arranged above the casters 303, and the V-shaped track 304 is connected to the template body 1.

[0048] During construction, first install the second translation guide rail 301 at a preset position according to the construction requirements and the size of the template body 1. Ensure that the second running mechanism 3 can stably support the movement of the template body 1. Next, install multiple caster brackets 302 on the second translation guide rail 301, and rotatably connect casters 303 on each caster bracket 302. The casters 303 enable the template body 1 to move smoothly through the rolling of the casters 303. A V-groove is provided on the outer circumferential surface of each caster 303, and the V-groove cooperates with the V-track 304 provided on the template body 1. During the installation process, ensure that the V-groove is aligned with the V-track 304 so that they can fit closely and achieve a stable guiding effect.

[0049] In this embodiment, the casters 303 are provided so that the template body 1 can be easily moved on the second translation guide rail 301, thereby achieving fast and flexible movement, greatly shortening the construction period, and improving construction efficiency. Through the cooperation of the V-groove and the V-track 304, the second running mechanism 3 provides more stable support and guidance for the template body 1, effectively reducing the shaking and deviation of the template during movement, and improving the accuracy and safety of construction. The second running mechanism 3 adopts a modular design and can be flexibly adjusted according to different construction requirements and template sizes, so that the running mechanism can be applied to various integrated pipe corridor construction scenes and has a wide range of applicability.

[0050] like Figure 7 As shown, in a preferred embodiment, the demoulding mechanism 4 includes a sliding support 401, on which a crank 402 is rotatably connected, and the crank 402 is threadedly connected to the second translation guide rail 301. Rotating the crank 402 drives the second translation guide rail 301 to slide on the sliding support 401 to adjust the position of the template body 1.

[0051] During construction, firstly, the crank handle 402 is rotated and connected on the sliding support 401, and a threaded connection is achieved between the crank handle 402 and the second translation guide rail 301. Then, the sliding support 401 is installed in a suitable position to ensure that it can stably support the movement of the second translation guide rail 301.

[0052] Before pouring, the construction personnel drive the second translation guide rail 301 to slide on the sliding support 401 by turning the crank 402. Due to the threaded connection between the crank 402 and the second translation guide rail 301, the rotation of the crank 402 can accurately control the moving distance and direction of the second translation guide rail 301. In this way, the construction personnel can move the template body 1 to a preset position to form a mold cavity with the inner template 5, and prepare for the pouring work.

[0053] After the pouring is completed and the concrete solidifies, the construction personnel use the demoulding mechanism 4 to perform the demoulding operation again. By turning the crank 402, the second translation guide rail 301 is driven to drive the template body 1 away from the pouring wall. Due to the stability and accuracy of the threaded connection, the template body 1 can be moved smoothly and accurately to achieve the demoulding process.

[0054] In this embodiment, the demoulding mechanism 4 is provided to make the movement of the template body 1 simple and convenient. The construction personnel only need to turn the crank 402 to complete the movement and positioning of the template without complicated manual operations. The fast and precise movement function of the demoulding mechanism 4 greatly shortens the construction period and improves the construction efficiency. Before pouring, the construction personnel can quickly position the template; after pouring, the construction personnel can quickly demould the template, which improves the construction efficiency. Through the threaded connection between the crank 402 and the second translation guide rail 301, the construction personnel can accurately control the movement distance and direction of the template body 1 to achieve precise positioning, which helps to ensure the precise fit between the template body 1 and the inner template 5 and improve the molding quality of the model cavity.

[0055] In actual application, the driving mode of the demoulding mechanism 4 can be set according to the construction requirements to improve the construction efficiency and the convenience of operation, such as using a motor to drive the crank 402 to rotate, or using a hydraulic cylinder to drive the template body 1 to move.

[0056] When the crank 402 is driven to rotate by the motor, a motor is first installed near the sliding support 401, and the power of the motor is transmitted to the crank 402 through a transmission device, such as a gear, a belt, etc., to ensure that the connection between the transmission device and the crank 402 is stable and reliable. Before and after pouring, the motor is started to drive the crank 402 to rotate, thereby driving the movement of the second translation guide rail 301 and the template body 1. By using the motor to drive the crank 402 to rotate, the automatic operation of the demoulding mechanism 4 is realized. The construction personnel only need to control the motor to automatically complete the movement and positioning of the template. The motor drive method can respond quickly and realize the rapid movement of the template. Compared with manual operation, the motor drive can greatly improve the construction efficiency and shorten the construction period. The tediousness of manual operation is reduced, and the speed and direction of rotation of the motor can be accurately controlled, thereby realizing the precise control of the template movement speed and distance, which helps to improve the accuracy of template positioning and construction efficiency.

[0057] When the formwork body 1 is driven to move by the hydraulic cylinder, the hydraulic cylinder is installed between the formwork body 1 and the sliding support 401, and the telescopic rod of the hydraulic cylinder is firmly connected to the formwork body 1 through the connecting piece to ensure that the telescopic rod of the hydraulic cylinder can move synchronously with the formwork body 1. Before and after pouring, the movement and positioning of the formwork body 1 are driven by controlling the telescopic movement of the hydraulic cylinder. The hydraulic cylinder has high thrust and stability and can easily drive the movement of the formwork body 1. Even in a construction environment with greater resistance, the hydraulic cylinder can maintain smooth telescopic movement to ensure the stability of the movement of the formwork body 1.

[0058] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the template body 1 includes a transverse back rib 101, a frame 102 is provided on the first side of the transverse back rib 101, a model plate 103 is provided on the first side of the frame 102, and a demoulding portion is provided on the model surface of the model plate 103.

[0059] When installing the formwork body 1, first assemble the skeleton 102 according to the construction requirements and the size of the formwork, including horizontal bars, vertical bars and frames. The skeleton 102 is mainly used to enhance the overall strength of the formwork body 1 and provide support for the transverse back ribs 101 and the model plate 103. The model plate 103 is installed on the first side of the skeleton 102, and the transverse back ribs 101 are installed on the second side of the skeleton 102. The transverse back ribs 101 are used to carry the tension screws to ensure the structural strength of the formwork body 1. The tension screws connect the outer formwork and the inner formwork 5 to ensure the structural stability of the casting cavity. The model plate 103 is the main component for forming the tunnel model cavity. A demoulding part is set on its model surface. The demoulding part is determined according to the specific construction environment and the formwork material to ensure that the formwork body 1 can be smoothly separated from the concrete during the demoulding process. The demoulding part includes applying a release agent on the model plate 103 or setting a fiberglass board.

[0060] In this embodiment, through the support of the transverse back ribs 101 and the skeleton 102, the template body 1 has a stable structure, can withstand various loads during the construction process, and ensure the molding quality of the pipe gallery. At the same time, the setting of the demoulding part makes the demoulding process smoother, reducing the demoulding time and labor costs. The demoulding part can ensure the molding effect of the pipe gallery, making the pipe gallery smooth and flat, reducing flaws and defects, and reducing finishing after pouring. The demoulding part can protect the model plate 103, and after proper care and maintenance, it can be reused many times, reducing construction costs.

[0061] like Figure 3 and Figure 8 As shown, in a preferred embodiment, a first connecting plate 104 and a second connecting plate 105 are respectively provided on both sides of the skeleton 102, a first connecting hole 106 is opened on the first connecting plate 104, and a second connecting hole 107 is opened on the second connecting plate 105, the first connecting hole 106 corresponds to the second connecting hole 107 one by one, and a quick release part 108 is provided in the first connecting hole 106 of one skeleton 102 and the second connecting hole 107 of the adjacent skeleton 102, the quick release part 108 is used to connect two adjacent skeletons 102, and the quick release part 108 is an aluminum film plate pin or a buckle, wherein the aluminum film plate pin includes a pin and a pin sheet.

[0062] During installation, splice two adjacent skeletons 102, the first connecting plate 104 of one skeleton 102 is in contact with the second connecting plate 105 of the other skeleton 102, and the first connecting hole 106 corresponds to the second connecting hole 107. Pass the pin through the corresponding first connecting hole 106 and the second connecting hole 107, and then insert the pin into the pin. And use a hammer or other tool to nail the pin tightly so that the first connecting plate 104 and the second connecting plate 105 are tightly connected together. Make sure that all quick-release parts 108 are tightened and the connection is firm and reliable. After completing the installation of the quick-release parts 108, carefully check the connection between the first connecting plate 104 and the second connecting plate 105 to ensure that all connections are tight and seamless, and there is no risk of leakage.

[0063] In this embodiment, by using the quick release part 108 to connect the first connecting plate 104 and the second connecting plate 105, the operator can quickly complete the connection and disassembly work, which greatly improves the construction efficiency. The quick release part 108 makes the connection process simple and fast, reduces unnecessary operation steps and time consumption, and reduces manpower input and working hours. The first connecting plate 104 and the second connecting plate 105 are tightly connected together by the aluminum film plate pin to form a stable connection structure, which not only ensures the stability of the outer template during the pouring process, but also effectively prevents the slurry from leaking from the joint. In addition, the workload of later finishing and cleaning is reduced, further reducing the construction cost. The use of the quick release part 108 makes the connection and disassembly of the skeleton 102 more convenient and quick. Compared with traditional connection methods, such as welding, screw fixing, etc., the quick release part 108 can significantly shorten the installation and disassembly time and improve the construction efficiency. It can be easily maintained and maintained, which provides convenience for the reuse of the skeleton 102. At the same time, since the connecting parts can be replaced, the service life of the skeleton 102 is extended, reducing the construction cost. The connection mode of the quick-release parts 108 makes the template body 1 more flexible in adapting to the construction of pipe corridors of different sizes and shapes. By adjusting the position and number of the template body 1, customization and scalability can be easily achieved to meet diverse construction needs.

[0064] In a preferred embodiment, the skeleton 102 is provided with a receiving groove on the first connecting plate 104 or the second connecting plate 105, and a seal is provided in the receiving groove. The seal is a rubber water stop strip, and the thickness of the seal is not less than the depth of the receiving groove.

[0065] In this embodiment, the size and shape of the receiving groove match the seal to ensure that the seal can be tightly embedded therein. The thickness of the seal is not less than the depth of the receiving groove to ensure that the seal can completely fill the receiving groove and make good contact with the side of the adjacent frame 102 to form an effective seal. By arranging the receiving groove on the connecting plate and installing the seal, the template body 1 can be effectively prevented from leaking during the pouring process.

[0066] like Figure 1 As shown, a template system for construction of an integrated pipe gallery in one embodiment of the utility model includes an inner template 5 and an outer template, and the outer template is the outer template for construction of the integrated pipe gallery mentioned above.

[0067] During construction, the inner formwork 5 is moved to the construction position by the trolley, and the outer formwork is installed at the corresponding position. After the casting cavity is built, casting is carried out. During the casting process, pay attention to controlling the casting speed and uniformity of the concrete to avoid problems such as hollowing and cracks. After the casting is completed, necessary maintenance work is carried out to ensure that the concrete reaches the designed strength. After the concrete solidifies, the inner formwork 5 is demolded by the mechanism on the trolley and moved to the next construction position. The clamping roller 213 of the first running mechanism 2 of the outer formwork is clamped to the first translation guide rail 214 to prevent the outer formwork from overturning. The outer formwork is demolded by the demoulding mechanism 4, and then the outer formwork is towed to move to the next construction position.

[0068] In this embodiment, a template system combining an inner template 5 and an outer template is used to make the construction process more orderly and efficient. The synergistic effect of the inner and outer templates simplifies the construction steps and shortens the construction period. The outer template shortens the movement and demoulding time of the template body 1 through the walking structure and demoulding mechanism 4, making the entire construction process more efficient.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
