Description

Technical Field

[0001] The utility model relates to the technical field of concrete storage devices, in particular to a storage device for modified manufactured sand high-performance concrete which is convenient for transportation. Background Technique

[0002] Manufactured sand is sand material made by taking quartz sand, limestone, feldspar and other ores as raw materials and going through multiple steps such as crushing, grinding, washing and screening, and can replace natural river sand for concrete preparation. Due to the round and smooth surface of river sand, when bonding with substances such as cement, the bonding degree and compressive effect are relatively poor. Because the particles of manufactured sand are rough and angular on the surface, when bonding with substances such as cement, there is often a better bonding degree, better compressive effect and longer service life. Therefore, manufactured sand is also widely used in the preparation of modified high-performance concrete.

[0003] Modified high-performance concrete is a product obtained by uniformly mixing raw materials such as manufactured sand, cement and aggregates. Before adding water and stirring, it is mostly stored in bags with inner linings through woven bags. The weight of a bag of concrete powder is usually about 50KG. These woven bags are usually equipped with inner linings, which can play a certain waterproof role. However, there are some functional deficiencies in the actual use process and there is room for improvement. For example, the weight of a single bag of concrete powder itself is relatively large. In the case of stacking multiple bags, it can only be transported by a forklift. When the front fork of the forklift forks up the concrete, it is easy to puncture the outer bag, causing powder leakage, and manual stacking is required, which is rather troublesome and does not have the function of being convenient for forking and transporting.

[0004] Now, a new storage device for modified manufactured sand high-performance concrete which is convenient for transportation is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a storage device for modified manufactured sand high-performance concrete which is convenient for transportation, so as to solve the problem of lacking the function of being convenient for forking and transporting mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A storage device for modified manufactured sand high-performance concrete which is convenient for transportation, including a woven bag body, an outer polyethylene waterproof film is adhesively bonded at the inner wall of the woven bag body, sealing stitches are respectively arranged on the left and right sides of the woven bag body, and a transfer assembly which is convenient for transportation and transfer is arranged at the bottom end of the woven bag body.

[0007] The transfer component includes a EU plastic plate, which is arranged at the bottom of the woven bag body. Two forklift insertion grooves are opened at the bottom end of the EU plastic plate. A lower polyester fiber woven annular belt is adhesively bonded to the bottom end of the EU plastic plate. An upper polyester fiber woven annular belt is arranged at the top end of the woven bag body. Hook-and-loop fasteners with a plush surface are respectively sewn and fixed on both sides of the top end of the lower polyester fiber woven annular belt. Loop-and-loop fasteners with a prickly surface are respectively sewn and fixed on both sides of the bottom end of the lower polyester fiber woven annular belt.

[0008] Preferably, the top end of the EU plastic plate and the bottom end of the woven bag body are bonded by an adhesive, and the vertical centerlines of the woven bag body and the EU plastic plate coincide.

[0009] Preferably, the front and rear ends of the woven bag body and the EU plastic plate are flush, and the forklift insertion grooves coincide with the vertical centerline of the EU plastic plate.

[0010] Preferably, the bottom end of the upper polyester fiber woven annular belt and the top end of the woven bag body are bonded by an adhesive, and the hook-and-loop fasteners with a plush surface and the loop-and-loop fasteners with a prickly surface are fitted together.

[0011] Preferably, a kraft paper inner liner bag is arranged inside the outer polyethylene waterproof film, and an inner polyethylene waterproof film is arranged on the inner wall of the kraft paper inner liner bag.

[0012] Preferably, the inner polyethylene waterproof film and the kraft paper inner liner bag are bonded by an adhesive, and the outer polyethylene waterproof film and the kraft paper inner liner bag are not connected.

[0013] Preferably, a plastic bottom support is adhesively bonded to the right side of the top of the woven bag body. An outer protective cover is fixedly connected to the top of the plastic bottom support. An RFID chip is arranged inside the outer protective cover.

[0014] Preferably, the bottom end of the RFID chip is connected to the top end of the plastic bottom support, and the positions of the outer protective cover and the plastic bottom support correspond to the positions of the forklift insertion grooves.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The storage device for modified manufactured sand high-performance concrete that is convenient for transportation not only realizes the function of being convenient for forklift transportation, but also realizes the functions of internal waterproofing and wear resistance, and also realizes the function of being convenient for inventory record.

[0016] (1) By setting up an EU plastic board, a forklift insertion slot, a lower polyester fiber woven annular belt, an upper polyester fiber woven annular belt, a hook-and-loop fastener with a soft side and a hook-and-loop fastener with a prickly side, during use, raw materials such as machine-made sand, cement, and aggregates are evenly mixed to form a modified machine-made sand high-performance concrete powder. The powder is filled into a woven bag body through a packaging device for storage, and the port is sealed with a sealing stitch, which is convenient for later sales. When transportation and transfer are needed, the forklift directly inserts the front fork into the forklift insertion slot at the bottom of the EU plastic board, and the EU plastic board lifts the whole woven bag body, completing rapid loading. When unloading, it can be unloaded by forklift or manually. The unloading worker grabs the fitting position of the lower polyester fiber woven annular belt and the upper polyester fiber woven annular belt, and then two people can lift a whole bag of concrete powder by sharing the force. The hook-and-loop fastener with a soft side and the hook-and-loop fastener with a prickly side can make the lower polyester fiber woven annular belt and the upper polyester fiber woven annular belt fit together, which is convenient for workers to grip, realizing the function of being convenient for forklift transportation;

[0017] (2) By setting up an inner polyethylene waterproof film, an outer polyethylene waterproof film, and a kraft paper inner lining bag, during use, the outer polyethylene waterproof film serves as the basic waterproof film of the woven bag body, which can prevent external rainwater from seeping into the inside of the woven bag body. The inner polyethylene waterproof film and the kraft paper inner lining bag form a set of inner linings. The surface of the machine-made sand particles is rough and angular, and it is easy to scratch the waterproof film. The inner linings composed of the inner polyethylene waterproof film and the kraft paper inner lining bag isolate the concrete powder as much as possible, reducing the probability of it cutting through the two waterproof films, realizing the function of internal waterproofing and wear resistance;

[0018] (3) By setting up an outer protective cover, a plastic bottom tray, and an RFID chip, during use, the RFID chip can store the production batch and production number of the concrete. When the concrete is transported outwards, the warehousing personnel hold a radio frequency reading device and can directly generate an outbound form by reading the number batch stored in the RFID chip, which is convenient for later inventory tracking. The outer protective cover and the plastic bottom tray are used to protect the RFID chip and prevent it from being damaged, realizing the function of being convenient for inventory record.
