Description

Technical Field

[0001] The utility model belongs to the technical field of drainage ditch prefabrication processing, and in particular relates to an assembled drainage ditch integral prefabrication mould. Background Art

[0002] During the municipal and housing construction process, temporary drainage ditches need to be built on site to meet the temporary drainage needs of the site. Traditional municipal and housing construction site drainage ditches are mostly in the form of brickwork or cast-in-place concrete. Brickwork drainage ditches are formed by combining bricks and mortar. The construction efficiency is low and the overall force is poor. They are easily cracked and deformed by uneven settlement of the base or external extrusion force, causing drainage ditch leakage and affecting the use function of the drainage ditch. Cast-in-place concrete drainage ditches are formed by installing a steel skeleton in the groove and pouring concrete in a vertical formwork. The deformation of the formwork can easily cause the concrete to be over-square, and the quality of the cast-in-place concrete structure is difficult to control. If the concrete is not maintained in time, it is easy to crack, which will also cause drainage ditch leakage and affect the use function of the drainage ditch. In addition, brickwork or cast-in-place concrete drainage ditches are temporary components used for one-time construction and cannot be reused.

[0003] The assembled drainage ditch can effectively solve the problems existing in the traditional brick-built or cast-in-place concrete drainage ditch. The assembled drainage ditch is mostly prefabricated by molds. The assembled drainage ditch prefabricated molds are also disclosed in the prior art. For example, the patent with publication number CN220807887U discloses an RPC drainage ditch ABS plastic-steel combination mold, including a plastic-steel mold body and a bottom flange. The bottom flanges are arranged on both sides of the plastic-steel mold body, a left combined side panel is arranged on the left side of the plastic-steel mold body, and a right combined side panel is arranged on the right side of the bottom flange. The right and left combined side panels are integrally provided with mounting feet at the bottom, and thickened locking groove sheets are provided in the mounting feet. Cross locking grooves are provided in the bottom flanges. The left and right combined side panels are respectively assembled with the plastic-steel mold body through the bottom flanges. The RPC drainage ditch ABS plastic-steel combination mold disclosed in the patent consists of a plastic-steel mold body and two sets of right combined side panels and left combined side panels on the sides. The right combined side panel and the left combined side panel are assembled with the plastic-steel mold body from both sides respectively. Through the combined fixed connection, the plastic-steel mold body can be dismantled and replaced, which is convenient for disassembly and replacement.

[0004] It is undeniable that the RPC drain ditch ABS plastic-steel combination mold disclosed in the patent can indeed achieve the above-mentioned effect, but it still has certain shortcomings: the plastic-steel mold body and the bottom flange are fixedly connected, and during the demoulding process, it is not easy to demould and it is easy to damage the solid edges and corners, affecting the physical appearance and quality of the assembled drain ditch; in addition, when laying the drain ditch prefabricated by the patented mold, there is no anti-leakage design at the interface of the two adjacent drain ditches, which is prone to water leakage and affects the use of the drain ditch.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0039] The following is a clear and complete description of the technical solution of the utility model patent. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example

[0041] See attached Figure 1-5 , an assembled drainage ditch integral prefabricated mold, comprising:

[0042] Bottom mold 1;

[0043] A core mold 2 is fixed at the middle position of the top of the bottom mold 1 and extends along the length direction thereof, a right enlarged core mold 3 is fixed at the right end of the core mold 2, and at least one molding convex strip 31 is fixed at the middle position of the outer wall of the right enlarged core mold 3;

[0044] The side mold 4 is symmetrically hinged on both sides of the bottom mold 1 and extends along its length direction; specifically, hinge seats 11 are fixed on the outer walls of both sides of the bottom mold 1, and hinge arms 41 corresponding to the hinge seats 11 are fixed on the outer walls of the side mold 4; corresponding hinge holes 111 are provided on the hinge seats 11 and the hinge arms 41, and the side mold 4 and the bottom mold 1 are hinged by using external pins (not shown in the drawings) to penetrate the hinge holes 111 on the hinge seats 11 and the hinge arms 41; in addition, a tension pad 42 is symmetrically welded at the middle position of the top of the side mold 4, and a mounting groove 421 is provided on the tension pad 42. When in use, a screw is placed in the mounting groove 421 of the two tension pads 42, and nuts are threadedly connected at both ends of the screw, and the nuts abut against the outer walls of the tension pad 42. In this way, the middle part of the side mold 4 can be reinforced, so that the side mold 4 will not bend and deform, thereby ensuring the quality of the prefabrication of the drainage ditch;

[0045] A right end mold 5 is arranged at the right end of the bottom mold 1, the bottom of the right end mold 5 is fixedly connected to the bottom mold 1 by bolts, and the two sides are fixedly connected to the side molds 4 by bolts; and the right end mold 5 abuts against the outer end of the right enlarged core mold 3;

[0046] The left end mold 6 is arranged at the left end of the bottom mold 1, the bottom of the left end mold 6 is fixedly connected to the bottom mold 1 by bolts, and the two sides are fixedly connected to the side molds 4 by bolts, and a spacing is left between the top and the inner walls of the two sides of the left end mold 6 and the core mold 2 to form a left enlarged core mold 7. It is not difficult to understand here that the left enlarged core mold 7 is a cavity;

[0047] In this embodiment, the sizes of the right enlarged core mold 3 and the left enlarged core mold 7 are larger than those of the core mold 2; the width of the right enlarged core mold 3 is equal to the width of the left enlarged core mold 7, so that the drainage ditches prefabricated using the prefabricated mold of this embodiment can be connected in a semi-socket manner for two adjacent drainage ditches; the core mold 2 is wide at the top and narrow at the bottom, and a distance is left between the outer walls on both sides and the inner walls of the side mold 4, and the shape of the core mold 2 can facilitate subsequent demolding; the right end of the side mold 4 is flush with the right end of the core mold 2, and the right end mold 5 abuts against the right end of the core mold 2.

[0048] Secondly, in the present embodiment, a distance is left between the left end of the side mold 4 and the left end of the core mold 2 (the length of the side mold 4 is shorter than the length of the core mold 2); the left end mold 6 includes an L-shaped mold 61 symmetrically arranged at the left end of the side mold 4 and fixedly connected to the left end of the side mold 4 by bolts, a top mold 62 fixed to the top of the two L-shaped molds 61 by bolts, and a vertical plate 63 fixed to the left ends of the two L-shaped molds 61 and the top mold 62 by bolts; wherein, the bottom end of the vertical plate 63 is fixedly connected to the bottom mold 1 by bolts; the distance between the inner wall of the L-shaped mold 61 and the core mold 2 is smaller than the distance between the side mold 4 and the core mold 2; a distance is left between the bottom wall of the top mold 62 and the top wall of the core mold 2; the vertical plate 63 abuts the left end of the core mold 2; in this way, the distance between the L-shaped mold 61 and the top mold 62 and the core mold 2 forms a left enlarged core mold 7.

[0049] It should be supplemented that a hoisting hole 43 is reserved at the top of the side mold 4, and the side mold 4 can be conveniently lifted with the help of the hoisting hole 43.

[0050] When in use, the prefabricated mold of the assembled drainage ditch in this embodiment is assembled according to the above relationship, and then concrete is injected into the gap between the core mold 2, the side mold 4 and the bottom mold 1. The two sides of the core mold 2 are wide at the top and narrow at the bottom, which can reduce the expansion pressure caused by the internal stress during pouring, and at the same time reduce the friction of the side wall of the core mold 2 when the mold is removed after inverted pouring. In addition, the screws set in the installation groove 421 of the pull pad 42 form a pulling force on the pull pad 42, which can improve the support strength of the side mold 4 and avoid the flexural deformation of the side mold 4, thereby ensuring the quality of the prefabricated drainage ditch. In addition, when pouring concrete, since a molding convex strip 31 is fixed on the middle position of the outer wall of the right enlarged core mold 3, a groove will be formed at the right end of the prefabricated drainage ditch. When in use, a sealing rubber water stop strip is pre-buried in the groove, which can achieve the anti-leakage effect of the socket-type interface of the assembled drainage ditch and ensure the normal use of the drainage ditch.

[0051] When demoulding, the pins inserted in the hinge holes 111 on the hinge seat 11 and the hinge arm 41 are pulled out, so that the side mold 4 can be demoulded in an outward-opening manner, which facilitates demoulding and avoids damage to the edges and corners of the entity, thereby ensuring the entity appearance and quality of the assembled drainage ditch.

[0052] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different options and changes. The scope of the utility model is intended to be defined by the claims and their equivalents.
