Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular relates to a casting and molding pre-assembly modularization technology and application. Background Art

[0002] With the development of the times, the demand for low-carbonization, industrialization and intelligence is increasing, and the industrialization and mechanization of various industries have also increased significantly. Compared with other industries, the degree of industrialization in housing construction lags behind.

[0003] As a formwork (mold) used in construction projects, building formwork has excellent economic benefits and has been widely used in recent years, gradually replacing the traditional hollow floor system; however, its main application scope is limited to the multi-rib floor technology, which prevents it from being fully utilized; the existing technology CN 111706073B one-way multi-rib formwork and installation method only realizes the mold industrialization of one-way multi-rib beams; it is unable to simultaneously solve the mold industrialization requirements of orthogonal cross beams, cross beams, high and low beams and other structural requirements.

[0004] In the application of the formwork box of the multi-rib floor, nailing is often used to fix it on the floor formwork, which consumes a lot of basic materials and also limits the speed and quality of construction; the prior art CN 221095844 U provides a connection method that effectively solves this problem, but drilling holes completely through the flange inevitably reduces the force-bearing capacity of the load-bearing rod such as the flange, which is disadvantageous to the entire formwork box system; and when the flange width is relatively wide, the length of the connector required to be used will also increase, which is not convenient for construction; and a large number of holes need to be tightened and removed, which undoubtedly increases the amount of labor on site, increases the time of individuals on the support frame, and increases safety hazards. Summary of the invention

[0005] In view of this, the present invention aims to provide a modular casting molding pre-assembly modular technology and product application with a reasonable structure.

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example 1

[0052] See also Figure 1-Figure 11 The casting pre-assembly modular technology of this embodiment is a modular technology that divides the floor slab formwork to be cast into a mold composed of multiple or one or more standardized modules under a certain modulus; the main carrier is a standardized formwork with a connection groove on the top surface, and its accessories are standardized bridge plates, standardized beam molds, standardized height increase blocks, connecting rods, connecting cards, and supplementary blocks and filling blocks; for the convenience of understanding, the standardized formwork is first introduced as follows: See also Figure 2-Figure 3 The standardized formwork (1) is composed of a square shell top (11) with connecting grooves (12) on all sides and side walls (13) extending obliquely downward from the four edges. When the side walls (13) are closed, they are turned over and extended outwardly parallel to the shell top (11) to form flanges (16), thereby forming a trapezoidal cavity with a hollow interior. The flanges (16) are drawn out to form a cavity structure. The inner side of the flange is mainly used to bear the load transmitted from the standardized formwork (1), and the outer side of the flange is mainly connected to other standardized formworks (1) or other templates to handle non-standard sizes. The outer side of the flange (16) is provided with a The positioning groove (15) can be used to quickly connect adjacent standardized mold shells (1) using a connecting card (151); the corners or four sides of the flange (16) of the standardized mold shell (1) are provided with quick-release notches (14), which are used in conjunction with standardized quick-release top supports to increase the use time and achieve the purpose of reducing costs and increasing efficiency; the connecting groove (12) and the positioning groove (15) are important supports for the standardized mold shell (1) to realize the pre-assembly modular technology of casting and forming, and are also the positions where the force is most concentrated. Further, a reinforcing plate and necessary thickening treatment are provided on the connecting groove (12) and the positioning groove (15).

[0053] The main function of the connecting groove (12) is to connect the standardized height-increasing blocks (4) together through the connecting rod (22) of the standardized bridge plate (2) or the connecting piece (31) of the standardized beam mold (3) or through the connecting rod (43), so as to combine them into an industrial mold of an orthogonal cross beam, a cross beam, a high-low beam, a beamless floor and a multi-rib beam system under a certain module. Example 2

[0054] The following embodiments will be introduced with numbers to provide a more vivid description of the product application of the present invention; the numbers introduced are not all the numbers of the embodiments, and therefore other embodiments with modular properties are within the scope of this embodiment, and the magnitude of the dimensions is described in millimeters (mm).

[0055] The dimensions of the standardized modules are highly consistent. Therefore, when controlling their dimensions, the standardized dimensions of the most common support systems on the market should be used. Considering that the main means of implementation today is manual placement, the weight of the product needs to be controlled to facilitate on-site implementation. The 1200 dimension of the disc-type steel pipe support frame can also meet the conventional requirements of on-site construction. In addition, the 600 dimension in its standard dimensions can be better integrated into the module. At this time, the outer contour dimensions of the formwork can be defined as 1200x1200 and 1200x600. Two connecting grooves (12) with a spacing of 600 are symmetrically arranged in the center in the direction of 1200, and one connecting groove (12) is centered in the direction of 600. At this time, 1200 and 600 are assembled together to obtain three connecting grooves (12) with a spacing of 600. The corresponding positioning grooves (15) and bridge plate connecting rods (22 ), the connecting piece (31) of the standardized beam mold (3), the connecting groove (42) of the standardized heightening block (4), the reserved hole for the tension screw, and the reserved hole for strengthening the connection between the accessories are all 600 in spacing; the spacing of the beams in the mold formed by the standardized mold shell of the above-mentioned size is 600, 1200, 1800, 2400, 3000, 3600, 4200 and other sizes with 600 as the module; the above sizes basically meet the current commonly used size requirements, and the remaining sizes less than 600 are implemented by connecting non-standard components; when the height of the beam under the plate is required to be 300, 400, 500, 600, the height of the beam under the plate of the mold shell can be set to 300 and 500, and the standardized heightening block (4) can be set to 100 in height. Through the combination, the above construction requirements can be met and the consumption of materials and energy in the production process can be reduced, thereby achieving the purpose of energy saving and emission reduction.

A plurality of standardized formworks (1) can be connected by pins to form a whole, and then hoisted to a designated position by a machine; through one or more operations, an operating surface is formed above the support system or a large-area dense-rib mold is directly formed, and then the standardized formwork (1) is manually laid on the remaining area, and the connection card (151) is placed during the laying process; according to the requirements of the beam height, the standardized height-increasing block (4) is connected to the standardized formwork (1) through a connecting rod (43) at the position where the height needs to be increased; according to the requirements of the detailed drawings, the standardized height-increasing block (4) is connected to the standardized formwork (1) at the position where the height needs to be increased; according to the requirements of the detailed drawings, the standardized height-increasing block (4) is connected to the standardized formwork (1) at the position where the height needs to be increased. The position of the beam is connected and installed with the connecting groove (12) or the heightening block connecting groove (42) provided around the shell top (11) of the standardized formwork (1) through the bridge plate connecting rod (22) to form the required beam-slab relationship; if there is a small beam, according to the requirements of the detailed drawing, the position of the small beam is connected and installed with the connecting groove (12) or the heightening block connecting groove (42) provided around the shell top (11) of the standardized formwork (1) through the connecting pieces (31) provided on both sides of the top surface of the small beam to form the main and secondary beam relationship; after confirming that the above products have been placed, the supplementary blocks (121) and the filling blocks (141) are laid, and then the subsequent construction methods such as steel bars, water and electricity reservation and pre-embedding are carried out. The subsequent construction methods are well known to technicians in the field and will not be repeated.
