Example Embodiment

[0036] Example one

[0037] Such as figure 1 with figure 2 As shown, the detachable steel core mold includes two support assemblies 100, and each support assembly 100 includes an elongated petal body 1 and an elongated petal body 2 2. One side of the petal body 1 is connected to the petal body 2. One side of the body two 2 is hinged by a hinge 14. The other side of the petal one 1 and the other side of the petal two 2 respectively have a plate body one 3 and a plate body two 4 formed by bending in the same direction. The body one 3 and the board body two 4 are arranged oppositely, the board body one 3 is hinged on the outer edge with a plurality of connecting arms 5 facing the board body two 4, and the board body 2 4 is hinged on the outer edge with a plurality of connecting arms 5 one-to-one correspondence The connecting arm two 6 of the plate body one 3 and the plate body two 4 are also provided with a pull rod 7 along the length of the valve body one 1 and the valve body two...

Example Embodiment

[0041] Example two

[0042] This embodiment is a method for manufacturing a prestressed concrete hollow beam by using the detachable steel core mold in the first embodiment, and the method includes the following steps:

[0043] a. Install the steel frame: build the steel frame on the flat ground, the steel frame is long, and the cross section of the steel frame is "mouth";

[0044] b. Install the peripheral plate: fix the peripheral plate on both sides of the steel frame, and the peripheral plate is attached to the outer side of the steel frame;

[0045] c. Install the corrugated pipe: fix the corrugated pipe in the steel frame, the corrugated pipe is arranged along the length of the steel frame, the corrugated pipe is distributed on both sides of the steel frame, and the two ends of the corrugated pipe extend out of the end of the steel frame;

[0046] d. Install anchor seats: fix anchor seats at both ends of the steel frame, use positioning steel bars to locate and fix the anchor seat...

Abstract

The invention provides a detachable steel core die, and belongs to the technical field of building engineering. The technical problems that a steel core die is not convenient to detach when an existing hollow beam is manufactured. The steel core die comprises two supporting assemblies, each supporting assembly comprises a first petal body and a second petal body which are both in a long strip shape; one side of the first petal body is hinged to one side of the second petal body; and the other side of the first petal body and the other side of the second petal body are provided with a first plate body and a second plate body which are formed by being bent in the same direction correspondingly. A plurality of first connecting arms facing towards the second plate body are hinged to the edge, close to the outer side, of the first plate body; and a plurality of second connecting arms in one-to-one correspondence with the first connecting arms are hinged to the edge, close to the outer side, of the second plate body. A pull rod in the length direction of the first petal body and the second petal body is further arranged between the first plate body and the second plate body, and the ends of the first connecting arms and the ends of the second connecting arms are both hinged to the pull rod. The invention further provides a method for manufacturing a prestress concrete hollow beam by the detachable steel core die. The steel core die is convenient and fast to detach.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and relates to a detachable steel mandrel and a method for making a prestressed concrete hollow beam by using the detachable steel mandrel. Background technique [0002] Concrete hollow beams are commonly used building materials in construction projects. Prefabricating concrete hollow beams on an independent site and then erecting them can speed up the progress of the project and save the construction period. When manufacturing the concrete hollow beam, the hollow structure is manufactured through the mold, which can reduce its own weight and save costs while ensuring strength. [0003] my country's patent (publication number: CN101701484A, publication date: 2010-05-05) discloses a reinforced concrete hollow beam with a length of 7-8m, a width of 0.2m, and a height of 0.55m. Four holes of φ100mm are arranged in parallel in the beam. The distance from the center of the hole is 125m...
