Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a casting device and method for intermediate nodes of vertical precast components. Background Technology

[0002] Columns made of reinforced concrete are the most basic load-bearing components in various engineering structures such as houses, bridges, and hydraulic structures. They are commonly used as supports for floors, piers, foundation columns, towers, and trusses. According to the manufacturing and construction methods, they are divided into cast-in-place columns and precast columns. Cast-in-place reinforced concrete columns have good integrity, but the amount of formwork work is large. Precast reinforced concrete columns are easier to construct, but the quality of the joint connections must be ensured.

[0003] However, the existing connection joints of precast reinforced concrete columns are reinforced by grouting, which is not suitable for the joint pouring of precast columns with anchor points. Using conventional pouring methods will cause the anchor points to be covered by concrete, making it impossible to anchor the steel strands. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device and method for casting intermediate nodes of vertical precast components. The device and method of this invention set anchor point grooves in the precast component node casting device so that the anchor points are not covered during concrete casting, so that the subsequent anchor point anchoring steel strands are not affected, and at the same time, it is convenient for subsequent anchoring adjustments.

[0005] To achieve the above-mentioned objectives, the technical solution provided by this invention patent is as follows:

[0006] A casting device for intermediate nodes of vertical precast components includes a feed plate, a discharge plate, a first anchor baffle, and a second anchor baffle. The feed plate and the discharge plate are arranged in parallel. The first anchor baffle and the second anchor baffle are respectively installed at both ends of the feed plate and the discharge plate. The first anchor baffle and the second anchor baffle are parallel to each other. The feed plate is perpendicular to the first anchor baffle. The feed plate and the discharge plate are fixed by bolts. The first anchor baffle and the second anchor baffle are also fixed by bolts. A discharge hopper is provided at the upper part of the discharge plate, and a feed hopper is provided at the upper part of the feed plate. The feed plate, the discharge plate, the first anchor baffle, and the second anchor baffle have cavities inside for concrete vibration and casting.

[0007] The feed plate is rectangular in shape. Reinforcing elbows are arranged parallel to each other on both sides of the feed plate. Multiple reinforcing horizontal plates are arranged between the reinforcing elbows. The reinforcing horizontal plates are parallel to each other. Bolt holes are opened at the upper and lower parts of the reinforcing elbows on both sides of the feed plate. A feed hopper is arranged between the reinforcing elbows.

[0008] The aforementioned discharge plate is rectangular in shape. Reinforcing elbow plates are arranged parallel to each other on both sides of the discharge plate, and multiple reinforcing cross plates are arranged parallel to each other between the reinforcing elbow plates. The height of the discharge hopper on the upper part of the discharge plate is the same as the height of the feed hopper on the feed plate. Bolt holes are provided at the upper and lower parts of the reinforcing elbow plates on both sides of the discharge plate, and the bolt holes provided at the upper and lower parts of the reinforcing elbow plates on both sides of the discharge plate are aligned with the bolt holes at the upper and lower parts of the reinforcing elbow plates on both sides of the feed plate. The feed plate and the discharge plate are fixedly connected by bolts.

[0009] The first anchor point baffle is rectangular in shape. An inwardly inclined casting plate is provided in the middle of the first anchor point baffle. Reinforcing elbow plates are arranged parallel to each other on both sides of the first anchor point baffle. Multiple reinforcing horizontal plates are arranged between the reinforcing elbow plates of the first anchor point baffle. Bolt holes are provided at the upper and lower parts of the reinforcing elbow plates on both sides of the first anchor point baffle. The structure of the second anchor point baffle is the same as that of the first anchor point baffle.

[0010] Connecting plates are provided on both sides of the aforementioned casting slab. The connecting plates are connected to the inner wall of the first anchor point baffle. The casting slab, the connecting plates, and the first anchor point baffle form an inwardly inclined anchor point groove.

[0011] A method for casting intermediate nodes of vertical precast components, the method specifically includes the following steps:

[0012] The first step is to prepare a casting device for intermediate nodes of vertical precast components. This device includes a feed plate, a discharge plate, a first anchor baffle, and a second anchor baffle. The feed plate and the discharge plate are arranged in parallel. The first anchor baffle and the second anchor baffle are respectively installed at both ends of the feed plate and the discharge plate. The first anchor baffle and the second anchor baffle are parallel to each other. The feed plate is perpendicular to the first anchor baffle. The feed plate and the discharge plate are fixed together by bolts. The first anchor baffle and the second anchor baffle are also fixed together by bolts. A discharge hopper is provided at the upper part of the discharge plate.

[0013] The second step is to fix the lower parts of the feed plate and the discharge plate to the upper side of the lower column with bolts. The feed plate and the discharge plate are set parallel to each other. The top of the lower column is provided with three anchor points, the middle of the end face of the lower column is provided with one anchor point, and the two sides of the end face of the lower column are provided with one anchor point respectively.

[0014] The third step involves fixing the lower parts of the first and second anchor point baffles to the upper side of the lower column using bolts. The first and second anchor point baffles are arranged in parallel. The anchor point on one side of the lower column is placed in the anchor point groove of the first anchor point baffle, and the anchor point on the other side of the lower column is placed in the anchor point groove of the second anchor point baffle. The cavities for concrete vibration and pouring inside the feed plate, discharge plate, first and second anchor point baffles are not connected to the anchor point grooves. The feed plate, discharge plate, first and second anchor point baffles are all hollow rectangular parallelepipeds.

[0015] The fourth step is to install the precast component node casting device on the lower column, then hoist the upper column onto the upper part of the precast component node casting device, and connect and fix the feed plate, discharge plate, first anchor point baffle and second anchor point baffle to the bottom of the upper column with bolts.

[0016] The fifth step involves the precast component node pouring device connecting and fixing the upper and lower columns, then vibrating and pouring concrete through the inlet. Once concrete overflows from the outlet, pouring is stopped. After the poured concrete reaches the required strength, the precast component node pouring device is removed from the upper and lower columns, completing the pouring of the precast component node.

[0017] In step 5 above, after the precast component node casting device is removed, the protruding parts of the cast concrete at the outlet and inlet are chiseled away to make the sides of the cast concrete smooth.

[0018] Based on the above technical solution, the present invention patent's device and method for casting intermediate nodes of vertical precast components has achieved the following technical advantages through practical application:

[0019] 1. The present invention provides a vertical precast component intermediate node casting device, which sets anchor point grooves in the precast component node casting device so that the anchor points are not covered during concrete pouring, so that the subsequent anchor point anchoring steel strands are not affected, and at the same time facilitates subsequent anchoring adjustments.

[0020] 2. The present invention provides a vertical precast component intermediate node casting device. By using the precast component node casting device, the steel bars between the upper and lower columns are fixedly connected without being connected and fixed, so that the upper and lower columns can be repeatedly disassembled and reassembled, which is convenient for subsequent replacement and disassembly.

[0021] 3.

[0028] like Figure 2 and 4As shown, the feed plate 41 is rectangular in shape. Reinforcing elbow plates 51 are arranged parallel to each other on both sides of the feed plate 41.

[0032] A method for casting intermediate nodes of vertical precast components, the method specifically includes the following steps:

[0033] The first step is to prepare a casting device for intermediate nodes of vertical precast components. This device includes a feeding plate 41, a discharging plate 42, a first anchor point baffle 43, and a second anchor point baffle 44.
