Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and in particular to a thin-wall box concrete component mould. Background Art

[0002] Box concrete components, also known as prefabricated box culverts, are a kind of prefabricated concrete box-shaped structures. It is a fast construction process for box culverts. It has the characteristics of factory prefabrication and on-site assembly. It is mainly used in engineering projects with many box culvert structures and short construction periods. The existing box concrete component production is to pre-make a negative mold or a positive mold, use the demoulding method to make an open box composed of the bottom surface and the surrounding side walls, and then stick the top surface to the opening of the open box to form a closed box body.

[0003] After the box body concrete components are formed, the inner and outer formworks need to be removed. In the prior art, the inner and outer formworks used for assembled box culverts are mostly one-piece structures with vertical casting method, which are fed from the vertical section direction of the box body structure. The casting opening is narrow and high, which makes casting difficult. These formwork bodies are bulky and inconvenient to carry, store and maintain. In addition, because concrete (especially ultra-high performance concrete UHPC / RPC) has a certain viscosity, the existing formworks are not convenient for construction and demoulding, and are time-consuming and labor-intensive to use. Therefore, when using the traditional method for casting and demoulding, there are the following problems:

[0004] 1. The inner mold can only be removed from a single direction, which can easily cause damage and waste to the outer and inner molds, making it impossible to produce quickly and on a large scale;

[0005] 2. Because concrete has a certain degree of adhesion, the connection between molds is usually a fixed connection. Therefore, it is very inconvenient during the disassembly process. In addition, during the disassembly process, if the bonding is too tight, it is necessary to use tools such as hammers to knock, which can easily damage the molds and components.

[0006] In summary, there is an urgent need for a thin-walled box concrete component mold that is easy to disassemble and improves the quality of concrete components to solve the above problems. Utility Model Content

[0007] In order to overcome the shortcomings of existing concrete component mold casting, the utility model provides a thin-wall box concrete component mold which is easy to disassemble and improves the quality of the concrete component.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment: A thin-walled box concrete component mold, such as Figure 1-Figure 5As shown, it includes an outer mold body A and an inner mold body B. The outer mold body A is composed of a first card plate 1, a second card plate 2 and a bottom plate 3, which are combined into a rectangular frame with the first card plate 1 as the length, the second card plate 2 as the width, and the bottom plate 3 as the bottom surface. There are two first card plates 1 and two second card plates 2. A card slot 101 is opened at the lower part of the first card plate 1 and the second card plate 2. The bottom plate 3 is circumferentially provided with a protrusion, and the length of the protrusion is shorter than the length of the bottom plate 3. The card slot 101 is clamped with the protrusion on the bottom plate 3, and the lower side of the bottom plate 3 is evenly and fixedly connected with a support plate. Short concave parts 301 are provided on both sides of the upper left and right parts of the first card plate 1, and hook parts 302 extending outward at an angle of ninety degrees are provided on both sides of the lower left and right parts of the first card plate 1. A long concave part 201 is symmetrically provided in the middle part of the second card plate 2, and the short concave part 301 and the long concave part 201 are both concave outward. The long concave portion 201 is located between the short concave portion 301 and the hook portion 302, the sum of the lengths of the short concave portion 301, the long concave portion 201 and the hook portion 302 is equal to the height of the first clamping plate 1, the upper part of the latch 7 is inserted into the short concave portion 301, and the lower part of the latch 7 is inserted into the hook portion 302. The inner mold body B is composed of a positioning cavity 4, a first shell 5 and a second shell 6. There are two first shells 5 and second shells 6. Both of the two first shells 5 and the second shells 6 are sleeved on the outer side of the positioning cavity 4. A cross is provided on the left and right sides of the positioning cavity 4. After the first shell 5 and the second shell 6 are spliced, the width and length of the inner side surface are equal to the length and width of the outer side surface of the positioning cavity 4. The first shell 5 and the second shell 6 completely wrap the circumference of the positioning cavity 4, and the contact surfaces of the first shell 5 and the second shell 6 are both 45-degree inclined surfaces and fully fit.

[0024] When pouring of concrete components is required, see Figure 1 First, insert the inner mold body B into the outer mold body A, and then you can start pouring the concrete component. When the concrete component needs to be demoulded after solidification, first pull it out from the first shell 5 and the second shell 6 through the crosses on both sides of the positioning cavity 4, and then squeeze the first shell 5 and the second shell 6 inward. At this time, because the contact surfaces of the first shell 5 and the second shell 6 are both 45-degree inclined surfaces and completely fit, the first shell 5 and the second shell 6 can be better squeezed inward to separate from the inner side of the concrete component. Then remove the first shell 5 and the second shell 6, and then pull the pin 7 upward, and then separate the first card plate 1 on the front and rear sides outward, and then separate the second card plate 2 to the left and right sides, and separate the bottom plate 3 downward from the concrete component, and the demoulding work of the concrete component can be completed. When it is necessary to continue pouring the concrete component, the inner mold body B and the outer mold body A are reassembled into Figure 1 The pouring can continue.
