Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sand boxes, in particular to a sand box convenient for unloading sand during the construction of cast-in-place beams. Background Technique
[0002] The sand box is applied to the construction of cast-in-place beams with steel pipe pile supports for unloading purposes. When the Bailey beam of the steel pipe pile support is erected, the construction of the cast-in-place beam begins. After the construction of the cast-in-place beam is completed, the support needs to be removed. At this time, it is very difficult to remove the support because the self-weight of the beam body is all pressed on the support. It is not an easy thing to remove the support. Therefore, when making the support, a sand box needs to be pre-set between the steel pipe pile and the distribution beam, and the sand box plays the role of a jack.
[0003] In traditional cast-in-place beam construction, the storage and unloading of sand materials usually adopt open stacking or simple containers. These methods often require manual drilling or the use of special tools to open holes during the sand unloading process, resulting in low efficiency of removing the support. Content of the Utility Model
[0004] The purpose of the utility model is to provide a sand box convenient for unloading sand during the construction of cast-in-place beams, so as to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A sand box convenient for unloading sand during the construction of cast-in-place beams, including a sand box between the distribution beam and the steel pipe column. The top of the steel pipe column is fixedly connected with the sand box. Sand discharge holes are opened on both sides of the sand box. Plugging blocks are slidably inserted into the sand discharge holes. Handles are arranged on the outer sides of the plugging blocks. Fixing holes are arranged on the tops of the plugging blocks. Fixing components convenient for adjustment are arranged on both sides of the sand box. A bearing member is arranged at the bottom of the distribution beam. A pressing plate is arranged at the bottom of the bearing member. Sand materials are arranged between the pressing plate and the sand box.
[0006] Preferably, the plugging block has a "T"-shaped arc block structure, and the structure between the pressing plate and the bearing member is detachable.
[0007] Preferably, the fixing component includes a fixing seat fixedly connected to the outer side of the sand box, and a receiving groove is opened on the fixing seat.
[0008] Preferably, an installation round block is arranged at the top of the receiving groove, and the installation round block is fixed on the fixing seat by bolts.
[0009] Preferably, a movable insertion rod is slidably inserted into the installation round block, and a limiting ring is arranged on the movable insertion rod in the receiving groove.
[0010] Preferably, a support spring is sleeved on the movable insertion rod, and the bottom of the movable insertion rod is inserted into the fixing hole.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] In the utility model, a sand box is used to store and distribute sand materials. When sand unloading is required, an operator pulls out a plugging block through a handle to open a sand outlet hole, so that the sand materials flow out through the sand outlet hole. A fixing component ensures that the plugging block remains in a closed state when sand unloading is not required, avoiding accidental leakage of the sand materials, realizing a rapid sand unloading process, and improving work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.
[0021] Please refer to Figures 1 to 6 , the utility model provides a technical solution: a sand box convenient for sand unloading in cast-in-situ beam construction, including a sand box 2 between a distribution beam 1 and a steel pipe column 3. The top of the steel pipe column 3 is fixedly connected with the sand box 2. Sand outlet holes 21 are formed on both sides of the sand box 2, and a plugging block 4 is slidably inserted on the sand outlet holes 21.
[0022] The plugging block 4 is in a "T"-shaped arc block structure. A handle 41 is welded to the outside of the plugging block 4. The setting of the handle 41 facilitates the operator to grasp and move the plugging block to open or close the sand outlet hole 21. A fixing hole 42 is opened at the top of the plugging block 4. Through the sliding insertion of the plugging block 4, the release of the sand material can be controlled. When sand unloading is required, the operator can pull out the plugging block 4 to allow the sand material to flow out through the sand outlet hole 21.
[0023] A pressure-bearing member 7 is fixedly connected to the bottom of the distribution beam 1. A pressure-bearing plate 8 is arranged at the bottom of the pressure-bearing member 7. The structure between the pressure-bearing plate 8 and the pressure-bearing member 7 is detachable. Sand material 6 is filled between the pressure-bearing plate 8 and the sand box 2. The sand material 6 is engineering sand. The pressure-bearing member 7 is located at the bottom of the distribution beam 1 and is used to bear the weight of the upper structure and transfer the weight to the pressure-bearing plate 8.
[0024] Adjustable fixing components are arranged on both sides of the sand box 2. The fixing components include fixing seats 5. The fixing seats 5 are fixedly connected to the outside of the sand box 2. A receiving groove 51 is opened on the fixing seats 5. An installation round block 52 is arranged at the top of the receiving groove 51. The installation round block 52 is fixed to the fixing seat 5 by bolts. A movable insertion rod 53 is slidably inserted into the installation round block 52.
[0025] A limiting ring 54 is welded on the movable insertion rod 53 inside the receiving groove 51. A support spring 55 is sleeved on the movable insertion rod 53. The bottom of the movable insertion rod 53 is inserted into the fixing hole 42. The model of the support spring 55 can be selected according to the actual working conditions. The fixing seat 5 and the movable insertion rod 53 are vertically distributed.
[0026] During the construction process of the cast-in-place beam, the sand box 2 is used to store and distribute the sand material 6. When sand unloading is required, the operator pulls out the plugging block 4 through the handle 41 to open the sand outlet hole 21, so that the sand material flows out through the sand outlet hole 21. The fixing components ensure that the plugging block 4 remains closed when sand unloading is not required, avoiding accidental leakage of the sand material.
[0027] When actual sand unloading is required, the movable insertion rod 53 is pulled upward, causing the support spring 55 to be compressed. At this time, the bottom of the movable insertion rod 53 is separated from the fixing hole 42. The operator pulls out the plugging block 4 through the handle 41 to open the sand outlet hole 21, so that the sand material flows out through the sand outlet hole 21, and rapid unloading of the sand material can be achieved.
[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
