Description

A pouring mold reserved for doors and windows

technical field

The utility model relates to the technical field of concrete pouring molds for doors and windows.

Background technique

Combination formwork is a tool formwork, which is the most widely used formwork in engineering construction. It consists of several types of panels with a certain modulus, corner forms, supports and connectors. The plate and corner formwork are the main components of the stereotyped composite formwork, generally composed of frames, panels and longitudinal and horizontal ribs.

In the pouring process of concrete prefabricated wall panels, shaped steel molds or wooden molds are often used as templates for openings such as doors and windows. Since the openings of doors and windows of different wall panels have different sizes, it is necessary to make multiple sets of formwork in advance to use the shaped formwork. At the same time, because the formwork will be compacted after the concrete is vibrated and compacted, it is difficult to remove the formwork, which often causes the formwork to be deformed and damaged. It is not conducive to the repeated use of templates; most of the wooden molds are used once, and the waste is large, and its production is mostly manual, with poor precision and difficult to guarantee quality.

Utility model content

The utility model provides a pouring mold reserved for doors and windows, which has the characteristics of convenient disassembly and assembly, reusability, long service life and less template consumption.

The utility model comprises angle molds, straight molds and connectors; the angle molds are 90° female angle molds, without chamfering or rounded corners, and its function is to form right angles reserved for doors and windows; the four angle molds and four The two straight dies are cross-spliced in pairs to form a rectangular frame, and then the corner dies are connected and fixed with the straight dies, or the ends of the corner dies and the straight dies are connected and fixed through connectors, and the connecting structure or connectors are used to Fix the corner formwork and straight formwork into a standard rectangle.

Preferably, the straight mold has different specifications, so as to adjust the overall size of the mold according to the size of the reserved doors and windows. Different specifications refer to different lengths in the longest direction of the 2 panels of the straight mold, and the length is determined by the formula c=a-2b, When assembling the mold, you only need to select the straight mold 2 according to the size of the reserved doors and windows, and make the specifications of the straight molds 2 on the opposite sides of the rectangle consistent to form a rectangular mold that meets the needs, so as to adapt to the size of more than two kinds of doors and windows Require.

Preferably, the connecting piece is composed of an alignment sleeve, a straight sleeve, and a pin, and the connection can be completed after the pin is inserted into the alignment sleeve through the straight sleeve. The role of the connection method is to avoid the misalignment between the angle mold and the straight mold.

Preferably, an alignment sleeve is rigidly fixed at both ends of the angle mold and the straight mold, and a straight sleeve is rigidly fixed at both ends of the straight mold and the angle mold. This arrangement facilitates the installation and removal of the pins.

Preferably, a notch is provided on the borders of the two ends of the angle mold connected to the straight mold, the role of which is to reduce the extrusion force at the connection, facilitate the disassembly of the mold, and at the same time avoid damage to the mold due to violent disassembly. When disassembling, you only need to remove the pin, then pry up one end of the straight mold, and the straight mold will come out, and then take off the other angle molds and the straight mold in clockwise or counterclockwise order to dismantle.

Preferably, a support structure is provided in the rectangular frame to ensure the overall bearing capacity of the mold and ensure that the mold is not deformed.

Preferably, the metal structure is a steel structure. The steel structure is simple to manufacture, low in cost, and high in strength, which is the optimal solution for realizing the technical solution provided by the utility model.

When the technical solution provided by the utility model is used in practice, the assembly can be completed by only cross-connecting the 4 said angle molds and the 4 said straight molds respectively two by two through the connectors to form a rectangle. When removing the formwork, you only need to open the connecting piece, then pry up one end of the straight formwork, and the straight formwork will come out, and then remove the other corner formwork and the straight formwork in a clockwise or counterclockwise order to remove it.

The beneficial effects produced by adopting the technical solution described in the utility model are:

The disassembly and assembly is convenient and labor-saving, which reduces the damage to the mold. At the same time, it can be adapted to the pouring of doors and windows of various sizes, which improves the utilization rate of the mold as a whole and reduces the consumption of the mold.

The corresponding relationship of the marks in the above drawings is: 1 angle mold; 11 gap; 2 straight mold; 3 connector; 31 quasi-set; Die length.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Since both the corner formwork and the straight formwork need to add a frame reinforcement panel, and adding a frame is a prior art, so this embodiment will not be described in detail.

The present embodiment takes the channel steel as an example to illustrate the utility model as the material for making the angle die and the straight die.

With reference to accompanying drawing 1 and accompanying drawing 2, a kind of reserved door and window pouring mold provided by the utility model comprises angle formwork 1, straight formwork 2, connector 3. Wherein, the angle die 1 is a female angle die with an angle of 90°, without chamfering or rounded corners. As shown in Figure 1, the four angle dies 1 and the four straight dies 2 are two by two respectively. Cross splicing to form a rectangle, and then connect the ends of the corner form 1 and the straight form 2 through the connecting piece 3, that is, assemble the reserved door and window pouring mold.

If the material and structure of the angle mold 1 and the straight mold 2 allow, they can be fixed directly by setting mortise and tenon structures and socket structures at both ends thereof.

Described connector 3 is made up of quasi sleeve 31, straight sleeve 32, pin 33, each two ends that angle mold 1 is connected with straight mold 2 are rigidly fixed with a quasi sleeve 31, and the two ends that straight mold 2 is connected with angle mold 1 each A straight sleeve 32 is rigidly fixed, and the connection can be completed after the pin 33 is inserted into the quasi sleeve 31 through the straight sleeve 32.

A triangular notch 11 for easy disassembly is respectively provided on the frame at the two ends of the angle mold 1 connected with the straight mold 2, and the essence is to cut off a corner of the channel steel wing plate.

At the same time, a supporting structure can also be added in the rectangular frame to ensure the overall bearing capacity of the mold and ensure that the mold is not deformed.

Combining the above embodiments, it can be seen that the technical solution provided by the utility model is convenient to disassemble and assemble when pouring reserved doors and windows holes, which reduces the damage to the mold, and can be adapted to the pouring of doors and windows of various sizes. It improves the utilization rate of the mold and reduces the consumption of the mold.
