Description

Technical Field

[0001] This utility model relates to the technical field of cast-in-place beam construction equipment, specifically a sand box for easy sand unloading during cast-in-place beam construction. Background Technology

[0002] Sand boxes are used in the construction of cast-in-place beams with steel pipe pile supports for unloading purposes. After the steel pipe pile support Bailey beam is erected, the construction of the cast-in-place beam begins. After the cast-in-place beam is completed, the support needs to be dismantled. At this time, it is difficult to dismantle the support because the weight of the beam is entirely on the support. It is not an easy task to dismantle the support. Therefore, when constructing the support, we need to set up sand boxes between the steel pipe piles and the distribution beam in advance. The sand boxes act as jacks.

[0003] A search of Chinese patent (publication number: CN222975695U) reveals a sand box for convenient sand unloading during cast-in-place beam construction. The sand box is located between a distribution beam and a steel pipe column. The top of the steel pipe column is fixedly connected to the sand box. Sand outlet holes are provided on both sides of the sand box. A sealing block is slidably inserted into the sand outlet hole. A handle is provided on the outside of the sealing block. A fixing hole is provided on the top of the sealing block. Fixing components that are easy to adjust are provided on both sides of the sand box. A pressure-bearing component is provided at the bottom of the distribution beam. A pressure plate is provided at the bottom of the pressure-bearing component. Sand is placed between the pressure plate and the sand box. This application utilizes a sand box for storing and distributing sand. When sand needs to be unloaded, the operator pulls out the sealing block by hand to open the sand outlet, allowing the sand to flow out through the outlet. The fixing component ensures that the sealing block remains closed when sand unloading is not required, preventing accidental leakage of sand and enabling a rapid sand unloading process, thus improving work efficiency. However, this device requires manual labor to climb to heights when discharging sand, greatly increasing the risk. At the same time, the gap between the pressure-bearing component and the sand box allows rainwater to enter the sand box, leading to poor sand discharge. Therefore, a sand box that facilitates sand unloading in cast-in-place beam construction is needed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a sand box that facilitates sand unloading during cast-in-place beam construction. This solves the problems of existing devices requiring manual labor at heights for sand unloading, which greatly increases the risk, and the gap between the pressure-bearing components and the sand box allowing rainwater to enter the sand box, resulting in poor sand discharge.

[0005] (II) Technical Solution The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a sand box for convenient sand unloading in cast-in-place beam construction, including a base, a box body installed on the top of the base, a bearing block provided inside the box body, a sand unloading mechanism provided on the surface of the box body, and a sealing mechanism provided on the surface of the box body.

[0006] Preferably, the sand unloading mechanism includes two sets of limiting frames symmetrically installed on the base surface. Each set of limiting frames has a sliding rod installed inside it. Each set of sliding rods has an adjusting block slidably connected to its surface. Each set of adjusting blocks has a connecting frame installed on its top. Each set of connecting frames has a blocking block installed on its side. Each set of limiting frames has a hanger installed at its bottom. The hanger is internally threaded with a long screw, and the top of the long screw is connected to a protrusion.

[0007] Preferably, both sides of the box are provided with sand discharge grooves adapted to the blocking block, the hanger is provided with an installation groove, a limit rod is installed in the installation groove, a moving block is slidably connected to the surface of the limit rod, and the protrusion and the moving block are connected by a round rod.

[0008] Preferably, the bottom end of the adjusting block is set as an inclined surface adapted to the protrusion, the top end of the long screw is rotatably connected to the protrusion through a rotating seat, and a first spring is sleeved on the surface of each set of sliding rods.

[0009] Preferably, the sealing mechanism includes a first connecting ring mounted on the surface of the bearing block, a second connecting ring mounted on the surface of the housing, multiple sets of bolts symmetrically mounted on the bottom of the first connecting ring, a nut threaded onto the surface of each set of bolts located at the bottom of the second connecting ring, and a second spring sleeved on the surface of each set of bolts.

[0010] Preferably, a retaining ring is installed on the surface of each set of bolts, and one end of the second spring is installed on the surface of the retaining ring, and the other end is installed on the bottom surface of the first connecting ring.

[0011] Preferably, the second connecting ring has multiple sets of through holes symmetrically formed to match the bolts.

[0012] The beneficial effects of this utility model are: 1) The sand box that facilitates sand unloading during the construction of the cast-in-place beam will cause the bearing block to descend due to the weight of the cast-in-place beam. Since the first connecting ring is connected to the bearing block, the bearing block will drive the first connecting ring to descend to the top of the box and fit tightly against the top of the box, thereby preventing rainwater from entering the box and ensuring subsequent sand discharge operations.

[0013] 2) The sand box that facilitates sand unloading during the construction of the cast-in-place beam can be easily operated by simply rotating the long screw to separate the protrusion from the adjusting block. At this time, the first spring will cause the blocking block to separate from the box body, thus eliminating the trouble of climbing to heights. Rotating the long screw in the opposite direction will cause the blocking block to seal the box body, making the operation simple. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: Depend on Figure 1-3 The diagram shows a sand box for easy sand unloading during cast-in-place beam construction, comprising a base 1, a box body 2 installed on the top of the base 1, a bearing block 3 inside the box body 2, and a sand unloading mechanism 4 on the surface of the box body 2. The sand unloading mechanism 4 includes two sets of limiting frames 401 symmetrically installed on the surface of the base 1. Each set of limiting frames 401 is equipped with a slide rod 402. Each set of slide rods 402 is slidably connected to an adjusting block 403. Each set of adjusting blocks 403 is equipped with a connecting frame 404 at its top. Each set of connecting frames 404 is equipped with a blocking block 405 on its side. Each set of limiting frames 401 is equipped with a hanger 406 at its bottom. The hanger 406 is internally threaded with a long screw 407. The top of the long screw 407 is connected to a protrusion 408.

[0018] Specifically, both sides of the housing 2 are provided with sand discharge grooves that are compatible with the blocking block 405. The hanger 406 is provided with an installation groove, and a limit rod is installed in the installation groove. A moving block is slidably connected to the surface of the limit rod. The protrusion 408 is connected to the moving block by a round rod. The bottom end of the adjusting block 403 is set as an inclined surface that is compatible with the protrusion 408. The top end of the long screw 407 is rotatably connected to the protrusion 408 through a swivel. A first spring is sleeved on the surface of each set of sliding rods 402.

[0019] With this structure, when performing sand removal operations, simply rotate the long screw 407 to cause the protrusion 408 to separate from the adjusting block 403. At this time, the first spring causes the blocking block 405 to separate from the box 2, thus removing sand and eliminating the hassle of climbing. Reverse rotation of the long screw 407 will cause the blocking block 405 to seal the box 2, making the operation simple.

[0020] Depend on Figure 1 and 4 As shown, a sealing mechanism 5 is provided on the surface of the housing 2. The sealing mechanism 5 includes a first connecting ring 501 installed on the surface of the bearing block 3, a second connecting ring 502 installed on the surface of the housing 2, and multiple sets of bolts 503 symmetrically installed at the bottom of the first connecting ring 501. A nut 504 is threadedly installed on the surface of each set of bolts 503 and located at the bottom of the second connecting ring 502. A second spring 505 is sleeved on the surface of each set of bolts 503.

[0021] Specifically, each set of bolts 503 has a retaining ring installed on its surface. One end of the second spring 505 is installed on the surface of the retaining ring, and the other end is installed on the bottom surface of the first connecting ring 501. The second connecting ring 502 has multiple sets of through holes symmetrically opened to match the bolts 503.

[0022] When this structure is in use, the weight of the cast-in-place beam will cause the bearing block 3 to descend. Since the first connecting ring 501 is connected to the bearing block 3, under the action of the bearing block 3, the first connecting ring 501 will descend to the top of the box 2 and fit tightly against the top of the box 2, thereby preventing external rainwater from entering the box 2 and ensuring subsequent sand removal operations.
