Embodiment 1

[0050] Such as Figure 8 As shown, the product cross beam prefabricated component 5 formed by one-time pouring using the molding die of a cross beam prefabricated component of this embodiment has a rectangular box structure, and the cross beam prefabricated component 5 includes surrounding side ribs 52, The outer surface of the rib 52 in the side area is provided with rib grooves 53 sunken inwards, and the ribs 52 in the side area form a cavity, and a plurality of rib beams 56 are evenly spaced along the length and width directions respectively, and the rib beams 56 connect the cross The internal cavity of the cross-beam prefabricated member 5 is divided into multiple rows and columns of grids, and the bottom of the grids is provided with a horizontal steel mesh 51, which is composed of a plurality of grid steel bars 55 vertically and horizontally intersecting, and the ribs The inner bottom of the beam 56 is also provided with matching rib beam reinforcement bars 54 , wherein ...

Embodiment 2

[0067] The molding die of a kind of cross beam prefabricated member of the present embodiment, basic structure is identical with embodiment 1, further, as Figure 4 As shown, the inner mold 2 in this embodiment is a thin-walled box, and the material is a steel plate or a hard plastic plate with a thickness of 3 mm to 5 mm. A reinforcing plate is provided inside the box to ensure that there is no obvious deformation when the concrete is vibrated. The lower part of the bottom plate of the inner mold 2 is provided with a layer of flexible cushion, and the thickness of the flexible cushion is 10mm-20mm. Specifically, the thickness of the flexible cushion layer in this embodiment is 10 mm. After the inner mold 2 is in place, it is pressed on the horizontal reinforcement mesh in block 11, and the flexible cushion layer contacts with the vertically and horizontally intersecting reinforcement on the horizontal reinforcement mesh and wraps the reinforcement extending out of block 11, w...

Embodiment 3

[0070] The forming die of a kind of cross beam prefabricated member of the present embodiment, basic structure is the same as embodiment 1, further, in the present embodiment, the side mold 4 is set up at the position of rib beam reinforcing bar 54 to pass through for reinforcing bar vertically. The rib beam reinforcement avoidance groove 45 in the length or width direction of the formwork, the rib beam reinforcement avoidance groove 45 penetrates the lower flange plate 43 downwards, the groove top of the beam reinforcement avoidance groove 45 is a semicircular arc structure, and the semicircular arc structure The depth is not less than 1 / 2 of the diameter of the rib beam steel bar 54, nor greater than the diameter of the rib beam steel bar 54, so the scope of adaptation is wider. In this embodiment, the bottom of the lower flange plate 43 of the side form 4 is laid with a layer of flexible cushion, which can effectively reduce the phenomenon of grout leakage when pouring concr...

Abstract

The invention discloses a forming die of a cross beam prefabricated part and a mounting and using method thereof, and belongs to the technical field of building prefabricated parts. The forming die comprises a steel bottom die body, a rectangular forming groove concaved inwards is formed in the center of the steel bottom die body, a plurality of rectangular blocks are evenly arranged in the forming groove in the length direction and the width direction at intervals, steel bar mounting grooves which are vertically crossed in the longitudinal and transverse directions are formed in the blocks, and the top height of the blocks is kept consistent with the top height of the outer edge position of the periphery of the steel bottom die body. The upper portion of each block is provided with an inner die which is matched with the block and is of a box structure, and the top of each inner die is provided with a lifting steel frame of a grid structure. The die aims at solving the problem that in the prior art, a cross beam prefabricated part with a reinforcing mesh is difficult to mold and pour at a time, the die can achieve one-time molding and pouring, demolding is convenient, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of building prefabricated components, and more specifically relates to a molding die for a prefabricated component of a cross beam with a reinforced concrete mesh and an installation and use method thereof. Background technique [0002] Prefabricated concrete components are prefabricated in factories with reinforced concrete as the basic material, and then assembled at the construction site. Prefabricated buildings can speed up construction, improve working conditions, and save labor. Structural components are produced on industrial assembly lines, with controllable quality and reduced environmental pollution. In recent years, my country has begun to vigorously promote prefabricated buildings. The Ministry of Housing and Urban-Rural Development has proposed: actively promote the industrialization of construction, improve the level of industrialized manufacturing of building accessories, promote the modulariz...
