Description

Technical Field

[0001] This invention relates to the field of integrated molding technology for pump room floor slabs, specifically to a casting equipment and a casting method for integrated molding of pump room floor slabs. Background Technology

[0002] The pump station's pump chamber structure consists of a flow channel layer, a pump layer, and a maintenance layer. (1) Flow channel layer: The flow channel layer is the basic structural layer at the bottom of the pump chamber. It is mainly responsible for guiding the water flow into the pump, ensuring a stable water flow and reducing hydraulic losses. The elevation of the flow channel layer in this project is ▽-1.0m~2.0m. (2) Pump layer: This is the installation area for the pumps and supporting equipment, including core components such as impellers, guide vanes, and drive shafts. The elevation of the pump layer in this project is ▽2.0m. (3) Maintenance layer: Located between the water turbine equipment layer and the motor layer, it is dedicated to equipment inspection and maintenance operations. It is also called the maintenance platform. The elevation of the maintenance layer in this project is ▽7.0m.

[0003] According to conventional construction techniques, the pump room structure is poured in two stages. The first stage involves pouring the pump floor to a height of ▽2.0m, leaving a horizontal construction joint, followed by the binding of structural reinforcement above ▽2.0m and the installation of formwork. The second stage involves pouring the maintenance floor to a height of ▽7.0m. The integrated pouring of the pump room structure presents certain construction challenges and requires advanced construction techniques. However, given the characteristics of small pump stations—narrow inlet channels and small slab areas—this project, with a single floor slab area of ​​3.4m*4.2m, allows for integrated pouring of the main pump room structure by designing the formwork and developing a pouring process, while ensuring construction safety. This approach saves time, improves quality, and reduces construction costs.

[0004] However, when the main structure of the pump room is cast as a whole, the construction of the second-floor suspended formwork usually relies on temporary supports for fixation, and the bottom formwork needs to be removed manually piece by piece after the pouring. Since the suspended formwork is located in the middle of the pump room and is encased in concrete, workers need to enter between it and the bottom of the pump room structure to dismantle it. On the one hand, it is difficult for workers to apply force, and on the other hand, the integral structure results in a large bottom area of ​​the suspended formwork, making it difficult to complete the formwork removal process manually. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a casting and molding device and a casting method for the integrated molding of pump room floor slabs. The device features a synchronous demolding assembly where a transmission rod group extends a hanging rod group into the bottom of the suspended formwork assembly, connecting the hanging rod group to the suspended formwork assembly. Then, the support of a crossbar on one side of the suspended formwork assembly is released, and the formwork of that side is dismantled using the weight of the crossbar. This allows for the simultaneous removal of the bottom formwork of one side of the suspended formwork assembly. This solves the problem that during the integrated casting of the pump room main structure, the construction of the second-layer suspended formwork typically relies on temporary supports for fixation, requiring manual removal of the bottom formwork piece by piece after casting. Furthermore, because the suspended formwork is located in the middle of the pump room and is encased in concrete, workers need to enter between it and the bottom of the pump room structure for dismantling. This presents challenges due to the difficulty in applying force and the large bottom area of ​​the suspended formwork caused by the integrated structure, making manual demolding difficult.

[0017] A casting method for integral molding of pump room floor slabs, using the aforementioned casting equipment.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a casting equipment and a casting method for integral molding of pump room floor slabs, which has the following beneficial effects:

[0020] 1. This casting and molding equipment supports the hanging formwork assembly in the combined template through a support frame. First, the columns in the support frame are fixed to the pump room base bottom formwork in the combined template. Then, horizontal bars are installed on both sides of the columns to support the hanging formwork assembly, so that the hanging formwork assembly is connected to the inner cavity of the casting template of the vertical wall, and the hanging formwork assembly, the pump room base bottom formwork, and the casting template of the vertical wall formwork are integrated. After the casting is completed and the floor slab cools down, the transmission rod group in the synchronous demolding assembly extends the hanging rod group into the bottom of the hanging formwork assembly, so that the hanging rod group is connected to the hanging formwork assembly. Then, the support of the horizontal bar on one side of the hanging formwork assembly is released, and the template of the hanging formwork assembly on that side is removed by the gravity of the horizontal bar, so that the template at the bottom of the hanging formwork assembly on one side can be removed at once.

[0021] 2. This casting and molding equipment uses a threaded tie rod in the threaded adjustment mechanism to connect the disconnected anti-overturning tie rod. After the two ends of the anti-overturning tie rod are connected to the two adjacent columns, the nut on the threaded sleeve is rotated, causing the nut and the threaded tie rod to rotate relative to each other. This causes the threaded sleeve to move relative to the threaded tie rod, tightening the disconnected anti-overturning tie rod and fixing the two adjacent columns. After adjustment, a protective sleeve is placed at the connection between the threaded sleeve and the threaded tie rod to prevent concrete from falling onto the threaded sleeve and threaded tie rod during casting and affecting the use of the threaded adjustment mechanism.

[0022] 3. This casting and molding equipment uses a threaded tie rod in the threaded adjustment mechanism to connect the disconnected anti-overturning tie rod. After the two ends of the anti-overturning tie rod are connected to the two adjacent columns, the nut on the threaded sleeve is rotated, causing the nut and the threaded tie rod to rotate relative to each other. This causes the threaded sleeve to move relative to the threaded tie rod, tightening the disconnected anti-overturning tie rod and fixing the two adjacent columns. After adjustment, a protective sleeve is placed at the connection between the threaded sleeve and the threaded tie rod to prevent concrete from falling onto the threaded sleeve and threaded tie rod during casting and affecting the use of the threaded adjustment mechanism.

[0023] 4. This casting and molding equipment uses a driven gear and a synchronous gear in the hanging rod assembly for transmission. When the synchronous gear rotates, it drives the driven gear and driven shaft to rotate together. When the driven shaft rotates, it moves by utilizing the threaded engagement with the mounting hole. In turn, the driven shaft drives the hanging rod at its end to move relative to the hanging ring at the bottom of the horizontal mold. When it is necessary to remove the horizontal mold, the hanging rod extends into the hanging ring at the bottom of the horizontal mold. At this time, the lock between the horizontal rod and the column is released, so that the horizontal rod is hung at the bottom of the horizontal mold through the hanging rod and the hanging ring. Then, the force applied to the horizontal rod, combined with the gravity of the horizontal rod, drives the horizontal mold to be removed. This avoids the difficulty of simple manual removal work because the horizontal mold is located at the bottom of the hanging mold assembly and is sandwiched between the hanging mold assembly and the bottom mold of the pump room base.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-14 A casting molding device includes: a support frame 1, a combined template 2, and a synchronous demolding assembly 3; the combined template 2 includes a suspended template assembly 21 and a pump chamber base bottom template 22, the suspended template assembly 21 being suspended above the pump chamber base bottom template 22; the support frame 1 is fixed to the pump chamber base bottom template 22, the support frame 1 includes columns 12 and crossbars 13, the columns 12 being located above the pump chamber base bottom template 22, the crossbars 13 being located on both sides of the columns 12 and below the suspended template assembly 21; the synchronous demolding assembly 3 includes a transmission rod group 31 and a hanging rod group 32, the transmission rod group 31 being located at the bottom of the crossbars 13, the hanging rod group 32 being located on one side of the transmission rod group 31, and the hanging rod group 32 being located at the bottom of the suspended template assembly 21.

[0041] In actual use, first connect the two sides of the combined template 2 with the casting template of the vertical wall to make the casting template of the vertical wall and the inner cavity of the combined template 2 connected, so as to facilitate the integral casting and molding.

[0042] In use, the support frame 1 supports the hanging formwork assembly 21 in the combined template 2. First, the column 12 in the support frame 1 is fixed on the pump room base bottom formwork 22 in the combined template 2. Then, the horizontal bar 13 is installed on both sides of the column 12. The horizontal bar 13 supports the hanging formwork assembly 21, so that the hanging formwork assembly 21 is connected to the inner cavity of the vertical wall casting template, and the hanging formwork assembly 21, the pump room base bottom formwork 22 and the vertical wall casting template form a whole. After the casting is completed and the floor slab cools down, the transmission rod group 31 in the synchronous demolding assembly 3 extends the hanging rod group 32 into the bottom of the hanging formwork assembly 21, so that the hanging rod group 32 is connected to the hanging formwork assembly 21. Then, the support of the horizontal bar 13 on one side of the hanging formwork assembly 21 is released, and the template of the hanging formwork assembly 21 on that side is removed by the gravity of the horizontal bar 13. Thus, the template at the bottom of the hanging formwork assembly 21 on one side can be removed at once.

[0043] Furthermore, the column 12 is provided with a locking hole 121, and the two crossbars 13 are connected by a mounting frame 132. The mounting frame 132 is fitted onto the column 12, and a locking post 133 is provided on the mounting frame 132, which is adapted to the locking hole 121. A crane 11 is installed on the top of the column 12. Anti-overturning tie rods 14 are diagonally intersecting between two adjacent columns 12. The two ends of the anti-overturning tie rods 14 are connected to the column 12 through universal joints 141. The column 12 is fixedly installed on the bottom mold of the pump chamber base 22, and a threaded adjustment mechanism 15 is provided in the middle of the anti-overturning tie rod 14. The mounting frame 132 used to connect the crossbars 13 is locked to the column 12 through the locking hole 121 and the locking post 133, so that the column 12 and the crossbars 13 form a fixed support frame 1, which is used to support the lifting mold assembly 21. The process involves fixing and supporting the columns. First, the columns 12 are fixed to the bottom mold 22 of the pump chamber base. Two adjacent columns 12 are fixed with anti-overturning tie rods 14. The universal joints 141 at both ends of the anti-overturning tie rods 14 are connected to the upper and lower ends of the columns 12. Then, the tension of the anti-overturning tie rods 14 is adjusted using the threaded adjustment mechanism 15 to tighten and stabilize the columns 12. Next, the mounting frames 132 of the two crossbars 13 are joined together and the mounting frames 132 are put on the bottom of the columns 12. Then, the crossbars 13 are lifted synchronously using the crane 11 so that the crossbars 13 are in the appropriate position (the bottom of the position of the lifting mold assembly 21). Then, the locking pins 133 are used to pass through the mounting frames 132 and cooperate with the locking holes 121 to fix the crossbars 13 to both sides of the columns 12, so that the crossbars 13 and the columns 12 form a fixed support frame 1 to fix and support the lifting mold assembly 21.

[0044] Furthermore, the crane 11 includes a take-up roller 111 and two traction cables 112; the traction cables 112 are wound around the take-up roller 111, and the other ends of the traction cables 112 are located on both sides of the column 12, and the other ends of the traction cables 112 are connected to the crossbar 13. Fixed pulleys 122 are provided on both sides of the top of the column 12, and the traction cables 112 pass around the fixed pulleys 122. The height of the crossbar 13 is adjusted by the take-up and unwinding of the traction cables 112 through the take-up roller 111 in the crane 11. When installing the crossbar 13 and the column 12, the crane 11 is started, which drives the take-up roller 111 to rotate. The take-up roller 111 winds the traction cables 112, and the traction cables 112 move under the support of the fixed pulleys 122 on both sides of the top of the column 12, thereby pulling the crossbar 13 upward.

[0045] Further, the threaded adjustment mechanism 15 includes a threaded pull rod 151, a threaded sleeve 152, and a protective sleeve 153. The anti-tipping pull rod 14 is disconnected in the middle. The threaded pull rod 151 and the threaded sleeve 152 are respectively connected to the disconnected part of the anti-tipping pull rod 14. The threaded sleeve 152 is sleeved outside the threaded pull rod 151, and the threaded sleeve 152 is threadedly connected to the threaded pull rod 151. The protective sleeve 153 is sleeved outside the disconnected part of the anti-tipping pull rod 14. In use, a rotatable nut is provided at the end of the threaded sleeve 152, and the nut is threadedly connected to the threaded pull rod 151. The adjustment mechanism 15 is connected to the threaded pull rod 151 via the threaded adjustment mechanism 15. The threaded tie rod 151, in conjunction with the threaded sleeve rod 152, connects the disconnected anti-overturning tie rod 14. After the two ends of the anti-overturning tie rod 14 are connected to the two adjacent columns 12, the nut on the threaded sleeve rod 152 is rotated, causing the nut and the threaded tie rod 151 to rotate relative to each other. This causes the threaded sleeve rod 152 to move relative to the threaded tie rod 151, tightening the disconnected anti-overturning tie rod 14 and securing the two adjacent columns 12. After adjustment, the protective sleeve 153 is fitted onto the connection between the threaded sleeve rod 152 and the threaded tie rod 151 to prevent concrete from falling onto the threaded sleeve rod 152 and the threaded tie rod 151 during pouring, thus affecting the use of the threaded adjustment mechanism 15.

[0046] Furthermore, the combined template 2 includes several rectangular steel frames 23, which are spliced ​​together to form the hanging formwork assembly 21 and the pump room base bottom formwork 22. A composite template 24 is laid on the rectangular steel frames 23. The side of the composite template 24 is provided with an elastic sealing strip 25 and an L-shaped sealing groove 26 located at the edge of the pump room base bottom formwork 22 and the hanging formwork assembly 21. The elastic sealing strip 25 matches the L-shaped sealing groove 26. The pump room base bottom formwork 22 and the hanging formwork assembly 21 are composed of several rectangular steel frames 23, and the composite template 24 is installed and laid using the rectangular steel frames 23. When the several rectangular steel frames 23 and the composite template 24 are assembled, the L-shaped sealing groove 26 located at the edge of the hanging formwork assembly 21 and the pump room base bottom formwork 22, together with the elastic sealing strip 25, makes the hanging formwork assembly 21 and the pump room base bottom formwork 22 form a sealed cavity to facilitate concrete pouring.

[0047] Furthermore, the composite template 24 is provided with vibration holes 241 on its exterior. The vibration holes 241 are arranged at equal intervals, and annular reinforcing ribs 242 are provided around the vibration holes 241. Matrix reinforcing ribs 243 are welded between the annular reinforcing ribs 242 and the composite template 24. The vibration holes 241 on the exterior of the composite template 24 are used during the pouring process to vibrate the concrete poured inside the suspended formwork assembly 21 and the pump room base bottom formwork 22 by inserting a vibrator into the vibration holes 241, thereby filling the concrete inside the suspended formwork assembly 21 and the pump room base bottom formwork 22.

[0048] Furthermore, the suspended formwork assembly 21 includes a horizontal formwork 211 and a vertical formwork 212. The horizontal formwork 211 is located above the horizontal bar 13, and the vertical formwork 212 is located above the horizontal formwork 211. The columns 12 are located on both sides of the horizontal formwork 211. By cooperating with the horizontal bar 13 in the suspended formwork assembly 21, the horizontal formwork 211 is supported by the horizontal bar 13 in the support frame 1, thereby supporting and fixing the horizontal formwork 211 and the vertical formwork 212.

[0049] Furthermore, the transmission rod assembly 31 includes a drive shaft 311, which is located in the middle of the crossbar 13 and passes through the crossbar 13. A drive bevel gear 312 is provided at the bottom end of the drive shaft 311, and a bevel gear transmission box 313 is provided on one side of the drive bevel gear 312. A synchronous gear 314 is provided at the output end of the bevel gear transmission box 313, and the synchronous gear 314 is connected to the hanging rod assembly 32. By driving the drive shaft 311 in the transmission rod assembly 31 to rotate, the drive shaft 311 drives the drive bevel gear 312 at its end to rotate. The drive bevel gear 312 drives the synchronous gear 314 to rotate through the bevel gear transmission box 313. The bevel gear transmission box 313 is composed of a transmission rod and a transmission bevel gear. The transmission bevel gear meshes with the drive bevel gear 312, and the synchronous gear 314 drives the hanging rod assembly 32 to move.

[0050] Furthermore, the hanging rod assembly 32 includes a driven gear 321, a driven shaft 322, and a hanging rod 323. A hanging ring 213 is provided at the bottom of the horizontal mold 211, and a mounting hole 131 is provided on the side of the horizontal rod 13. The driven shaft 322 is installed inside the mounting hole 131, and the hanging rod 323 is located at the front end of the driven shaft 322, directly opposite the hanging ring 213. The driven gear 321 is located on the driven shaft 322, and the driven shaft 322 is threadedly connected to the mounting hole 131. The driven gear 321 meshes with the synchronous gear 314. Transmission occurs through the driven gear 321 and the synchronous gear 314 in the hanging rod assembly 32. When the synchronous gear 314 rotates, it drives the driven gear 321 and the driven shaft 322. When the driven shaft 322 rotates together, it moves by utilizing the threaded engagement with the mounting hole 131. This causes the driven shaft 322 to move relative to the hanging rod 323 at its end relative to the hanging ring 213 at the bottom of the horizontal mold 211. When the horizontal mold 211 needs to be removed, the hanging rod 323 extends into the hanging ring 213 at the bottom of the horizontal mold 211. At this time, the lock between the horizontal rod 13 and the column 12 is released, allowing the horizontal rod 13 to be hung at the bottom of the horizontal mold 211 through the hanging rod 323 and the hanging ring 213. Then, by applying force to the horizontal rod 13, the horizontal mold 211 is removed by combining the force with the gravity of the horizontal rod 13. This avoids the difficulty of simple manual removal work because the horizontal mold 211 is located at the bottom of the lifting mold assembly 21 and is sandwiched between the lifting mold assembly 21 and the bottom mold 22 of the pump chamber base.

[0051] In practical applications, the hanging rod 323 is rotatably connected to the driven shaft 322 through the mounting plate, and the crossbar 13 is provided with a guide groove 324 to restrict the mounting plate to only move horizontally.
