Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing four-legged hollow blocks, in particular to a four-legged hollow block steel mold. Background Art

[0002] The embankments along the river and the coast, the breakwaters of the ports and fishing ports, etc., all require good slope protection and minimize the overtopping of waves as much as possible, that is, there is a requirement for wave elimination. Figure 6 The four-legged hollow block 7 shown is manufactured by pouring concrete into a steel mold and solidifying it. Due to the special shape of the four-legged hollow block, the large number of required blocks, and the heavy weight (generally a single block can weigh several tons), the templates used are all customized fixed steel molds.

[0003] The traditional four-legged hollow square steel mold mainly includes a bottom mold, a top mold, and a side mold composed of four sides. However, due to the large size and weight of the steel mold, the upright four-sided side mold is very easy to fall over after demolding and injure workers, which poses a great safety hazard. It is also time-consuming and laborious to straighten the tilted side mold during assembly (molding). In order to solve this problem, the application number CN202123161505.0 is named "A four-legged hollow square steel mold based on wave-breaking construction of coastal roads". It adopts a structure composed of two half molds and a base, which solves the problem of the side mold being easy to fall over, but if Figure 6 As shown, the two side elevations of the four legs 71 of the four-legged hollow block 7 are in a vertical state. Due to the design requirements of the four-legged hollow block 7 product, its two side elevations must remain vertical, and the side elevations cannot be set to be inclined. The use of the above-mentioned two half-mold matching structure is prone to mold jamming during demoulding, and even makes it impossible to demould, which seriously affects production efficiency and product quality. Therefore, its structure needs to be further improved. Utility Model Content

[0004] The purpose of this utility model is to make up for the above-mentioned deficiencies and disclose to the public a four-legged hollow square steel mold with a reasonable structure and convenient demoulding.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A four-legged hollow square steel mold includes a bottom mold, a top mold and a side mold. The side mold includes a first side mold assembly and a second side mold assembly.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below with reference to the accompanying drawings:

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0029] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0030] like Figures 1 to 6As shown, a four-legged hollow square steel mold includes a bottom mold 1, a top mold 2 and a side mold. The side mold includes a first side mold component 3 and a second side mold component 4. The first side mold component 3 and the second side mold component 4 are respectively provided with a core mold 5. The first side mold component 3 is composed of a first side surface 31 and a second side surface 32, and the second side mold component 4 is composed of a third side surface 41 and a fourth side surface 42.

[0031] The first side mold assembly 3 is composed of a first side surface 31 and a second side surface 32 to form a "7"-shaped structure, and the second side mold assembly 4 is composed of a third side surface 41 and a fourth side surface 42 to form a "7"-shaped structure. The first side mold assembly 3 and the second side mold assembly 4 are combined to form a side mold with a rectangular-shaped cross-section.

[0032] The core mold 5 is detachably matched with the first side mold assembly 3 and the second side mold assembly 4.

[0033] The core mold 5 is provided with a handle 51 .

[0034] The outer periphery of the core mold 5 is provided with a limiting rib 52 .

[0035] A reinforcement member 53 is provided across the outer side of the core mold 5 .

[0036] The core mold 5 is removable, allowing for easier demolding. When removing the core mold 5, the operator can grasp the handle 51 and reinforcement 53 to facilitate force application. The reinforcement 53 not only facilitates force application but also increases the strength of the core mold 5. During installation, the limiting rib 52 limits the insertion depth of the core mold 5, improving assembly efficiency and positioning accuracy.

[0037] The top mold 2 includes a horizontal portion 21 and inclined portions 22 symmetrically arranged on both sides of the horizontal portion 21. The upper ends of the inclined portions 22 are flush with the upper ends of the side molds.

[0038] The top mold 2 is provided with a top mold reinforcement rib 2a. The provision of the top mold reinforcement rib 2a can improve the strength of the top mold 2.

[0039] The front and rear sides of the top form 2 are open. When manufacturing the four-legged hollow blocks 7, workers sometimes need to stand on the top form 2 to operate. The open front and rear sides make it easier for workers to climb onto the top of the top form 2. This makes it easier to clean concrete accumulated on the top form 2 during pouring, making it easier for workers to operate.

[0040] The first side mold assembly 3 and the second side mold assembly 4 are both provided with a roller assembly 6. The provision of the roller assembly 6 facilitates the movement of the first side mold assembly 3 and the second side mold assembly 4 during mold assembly and demolding.

[0041] The bottom mold 1 is provided with a base frame 11 and bottom mold reinforcement ribs 12. The provision of the base frame 11 and the bottom mold reinforcement ribs 12 can increase the strength of the bottom mold 1. In addition, the provision of the base frame 11 can improve the integrity of the bottom mold 1.

[0042] like Figure 3 As shown, the four-legged hollow square steel mold of the present invention is composed of a bottom mold 1, a top mold 2, a first side mold assembly 3 and a second side mold assembly 4. The first side mold assembly 3 is composed of a first side surface 31 and a second side surface 32, and the second side mold assembly 4 is composed of a third side surface 41 and a fourth side surface 42. The vertical projections of the first side mold assembly 3 and the second side mold assembly 4 are in a "7"-shaped structure. Such an arrangement can prevent the first side mold assembly 3 and the second side mold assembly 4 from tipping over while ensuring that the side elevation of the product is straight, avoiding damage to corners, ensuring smooth demoulding, avoiding the occurrence of mold jamming, and improving production efficiency and product quality.

[0043] Additionally, the top formwork 2 is independently designed, allowing it to be removed early during initial concrete set, facilitating finishing, reducing air bubbles, and enhancing aesthetics. It also acts as a restraining force between the two side panels, enhancing the overall stability of the steel formwork. The removable core formwork 5 can be removed outward for easy demoulding.

[0044] like Figure 1 As shown, after the mold is assembled, the first side mold assembly 3 and the second side mold assembly 4 are fixed to the outer periphery of the bottom mold 1, and the top mold 2 is fixed to the middle part of the upper end of the side mold composed of the first side mold assembly 3 and the second side mold assembly 4. The top mold 2 includes a horizontal portion 21 and an inclined portion 22, and its inclined portion 22 does not extend to the four legs 71 of the four-legged hollow block 7. In this way, the four legs 71 above the four-legged hollow block 7 are completely open, serving as a concrete inlet for pouring concrete, which facilitates construction, can increase the amount of concrete poured per unit time, improve the concrete pouring efficiency, and thus improve production efficiency.

[0045] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
