Description

Technical Field

[0001] This utility model relates to the field of concrete pouring mold technology, and in particular to modular concrete pouring molds for slope retaining wall construction. Background Technology

[0002] Slope retaining walls are important structures for preventing landslides and soil erosion. Current construction methods mostly use on-site formwork and pouring, which has problems such as low efficiency of formwork assembly, difficulty in dismantling formwork, and poor accuracy of concrete component connection.

[0003] For example, CN215165197U discloses a template for pouring concrete retaining walls, including two first fixed templates and two second fixed templates. The outer wall of the first fixed template has two symmetrically arranged concave slots. The outer wall of the second fixed template is fixedly connected to two symmetrically arranged T-shaped blocks. The outer walls of the two T-shaped blocks on the same side are slidably connected to the inner walls of the two concave slots. This utility model has concave slots, T-shaped blocks, first reinforcing blocks, and second reinforcing blocks.

[0004] The standard formwork for this concrete retaining wall relies on a conventional interlocking structure, which is prone to misalignment due to concrete pressure, affecting the consistency of the component's geometric dimensions. Furthermore, the bottom of the mold is flat, and the concrete becomes quite heavy after solidification, making it difficult to pour out the concrete blocks. Therefore, it is necessary to design a modular concrete pouring mold for slope retaining wall construction to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a modular concrete pouring mold for slope retaining wall construction, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A modular concrete pouring mold for slope retaining wall construction includes bolt handles. Eight bolt handles are provided, divided into two groups of four. The bottom of the four bolt handles on the front side is threadedly connected to a second mold assembly, and the bottom of the four bolt handles on the rear side is threadedly connected to a first mold assembly. The tops of the first mold assembly and the second mold assembly are fixedly connected to an auxiliary assembly through the common thread of the bolt handles.

[0008] The auxiliary component includes a connecting plate, with eight third screw holes on the upper left and upper right sides of the connecting plate. An arc-shaped base plate is fixedly connected to the bottom of the connecting plate, and U-shaped plates are fixedly connected to both ends of the arc-shaped base plate. A slot is formed inside the connecting plate.

[0009] Preferably, the first mold assembly includes a first template, with first screw holes on the upper left and upper right sides of the first template, and four first screw holes are provided. The front end of the first template has multiple first circular grooves, and multiple first circular blocks are fixedly connected to the inner wall of the first template. The rear end of the first template has multiple I-shaped slots.

[0010] Preferably, the second mold assembly includes a second template, with second screw holes on the upper left and upper right sides of the second template, multiple second circular grooves on the front center of the second template, multiple second circular blocks fixedly connected to the rear end of the second template, and an I-shaped insert fixedly connected to the front end of the second screw hole.

[0011] Preferably, the first mold assembly and the second mold assembly are symmetrically distributed, and the front end face of the first mold assembly and the rear end face of the second mold assembly are in contact with each other. The auxiliary assembly is located at the middle of the outer side of the first mold assembly and the second mold assembly. The eight bolt handles pass through the third screw hole, the first screw hole and the second screw hole respectively and are distributed in a rectangular array.

[0012] Preferably, the outer shape of the arc-shaped base plate is a downwardly convex arc structure, and the arc range of the arc-shaped base plate is 120°.

[0013] Preferably, the openings of the two U-shaped plates are both facing upwards, and the two U-shaped plates are fixedly welded to the middle of the left side wall and the middle of the right side wall of the connecting plate, respectively. The connecting plate is fixedly connected to the middle of the outer side of the first template and the second template by bolts.

[0014] Preferably, the plurality of first circular grooves are linearly distributed at equal intervals on the front end face of the first template, the distance between two adjacent first circular grooves is 10cm, and the first circular blocks correspond one-to-one with the first circular grooves and are coaxially distributed.

[0015] Preferably, the plurality of I-shaped slots are evenly distributed in a concave structure on the rear end face of the first template, and the positional dimensions of the plurality of I-shaped slots are adapted to the positional dimensions of the I-shaped inserts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this utility model, multiple I-shaped slots at the rear end of the first template in the first mold assembly are matched one-to-one with I-shaped inserts fixedly connected to the front end of the second template in the second mold assembly, forming a precise and stable connection structure. At the same time, eight bolts arranged in a rectangular array pass through the first screw hole, the second screw hole, and the third screw hole respectively, firmly fixing the first mold assembly, the second mold assembly, and the auxiliary components. This double fixing structure can effectively resist the pressure generated during concrete pouring, avoid template misalignment, ensure that the geometric dimensions of the poured concrete components are consistent, and greatly improve the accuracy and quality of the components.

[0018] 2. In this utility model, the U-shaped plate enhances the overall strength of the auxiliary components, the slot improves the overall assembly accuracy of the mold, and the 120° downward convex arc design of the arc base plate 42 enables the mold and concrete block to form a non-planar contact during the demolding stage after the concrete has solidified. The pressure distribution at the contact point is more uniform, reducing the frictional resistance and jamming risk of traditional planar contact, and achieving dual convenience of mold ejection and material pushing operation.

[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] The modular concrete pouring mold used in slope retaining wall construction includes bolt handles 1. There are eight bolt handles 1, which are divided into two groups of four. The bottom of the four bolt handles 1 on the front side is connected to the second mold assembly 3 by a common thread. The bottom of the four bolt handles 1 on the rear side is connected to the first mold assembly 2 by a common thread. The top of the first mold assembly 2 and the second mold assembly 3 are fixedly connected to the auxiliary assembly 4 by the common thread of the bolt handles 1.

[0030] In this embodiment, the auxiliary component 4 includes a connecting plate 41. The upper left and upper right sides of the connecting plate 41 are provided with third screw holes 44, and there are eight third screw holes 44. An arc-shaped base plate 42 is fixedly connected to the bottom of the connecting plate 41. U-shaped plates 43 are fixedly connected to both ends of the arc-shaped base plate 42. A slot 45 is provided inside the connecting plate 41. The outer shape of the arc-shaped base plate 42 is a downward convex arc structure, and the arc range of the arc-shaped base plate 42 is 120°. The opening direction of the two U-shaped plates 43 is upward, and the two U-shaped plates 43 are fixedly welded to the middle of the left side wall and the middle of the right side wall of the connecting plate 41, respectively. The connecting plate 41 is fixedly connected to the middle of the outer side of the first template 21 and the second template 31 by bolt rod 1.

[0031] Through the above scheme: when the modular concrete pouring mold is working in the construction of the slope retaining wall, the connecting plate 41 in the auxiliary component 4 is fixedly connected to the first template 21 and the second template 31 at the middle position on the outer side through eight third screw holes 44 opened on the left and right sides of its upper end, together with the bolt rod 1. The arc-shaped bottom plate 42 with a 120° downward convex arc structure fixed at the bottom of the connecting plate 41 can cooperate with the first mold component 2 and the second mold component 3 to form the bottom arc contour of the pouring space. The U-shaped plate 43 with its opening facing upward and fixedly welded at both ends of the arc-shaped bottom plate 42 can increase the... The auxiliary component 4 enhances structural stability and assists in positioning. The slot 45 inside the connecting plate 41 further improves the fitting accuracy with other components. The arc design of the arc-shaped base plate 42 facilitates the ejection of the mold after the concrete has solidified and also makes the material pushing operation convenient. The eight third screw holes 44 ensure the firmness of the connection between the connecting plate 41 and the first template 21 and the second template 31. The U-shaped plate 43 enhances the overall strength of the auxiliary component 4, and the slot 45 improves the overall assembly accuracy of the mold, thereby improving the stability of the mold and the pouring efficiency, which is conducive to the smooth progress of modular construction.

[0032] In this embodiment, the first mold assembly 2 includes a first template 21. The upper left and upper right portions of the first template 21 each have first screw holes 23, and four of these first screw holes 23 are provided. The front end of the first template 21 has multiple first circular grooves 22. Multiple first circular blocks 24 are fixedly connected to the inner wall of the first template 21. The rear end of the first template 21 has multiple I-shaped slots 25. The second mold assembly 3 includes a second template 31. The upper left and upper right portions of the second template 31 each have second screw holes 33. The middle of the front end of the second template 31 has multiple second circular grooves 32. The rear end of the second template 31 is fixedly connected to multiple second circular blocks 34. The front end of the second screw holes 33 is fixedly connected to an I-shaped insert 35. The first mold assembly 2 and the second mold assembly 3... The components 3 are symmetrically distributed, and the front end face of the first mold component 2 and the rear end face of the second mold component 3 are in contact with each other. The auxiliary component 4 is located in the middle of the outer side of the first mold component 2 and the second mold component 3. The eight bolt handles 1 pass through the third screw hole 44, the first screw hole 23 and the second screw hole 33 respectively and are distributed in a rectangular array. Multiple first circular grooves 22 are linearly distributed at equal intervals on the front end face of the first template 21. The distance between two adjacent first circular grooves 22 is 10cm. The first circular block 24 corresponds to the first circular groove 22 and is distributed coaxially. Multiple I-shaped slots 25 are evenly distributed in a concave structure on the rear end face of the first template 21, and the position and size of the multiple I-shaped slots 25 are matched with the position and size of the I-shaped insert 35.

[0033] Through the above scheme: When the modular concrete pouring mold in the construction of the slope retaining wall is in operation, the first template 21 in the first mold assembly 2 and the second template 31 in the second mold assembly 3 are symmetrically distributed. Multiple I-shaped slots 25 at the rear end of the first template 21 are matched one-to-one with the I-shaped inserts 35 fixedly connected to the rear end of the second template 31, so that the front end face of the first mold assembly 2 and the rear end face of the second mold assembly 3 fit together. Multiple first circular grooves 22, linearly distributed at equal intervals of 10cm at the front end of the first template 21, are fixedly connected to its inner wall and correspond one-to-one with the first circular blocks 24 distributed coaxially. These, together with the multiple second circular grooves 32 in the middle of the front end and the multiple second circular blocks 34 at the rear end of the second template 31, form the inner contour of the pouring space. Simultaneously, the four first screw holes 23 on the upper left and right sides of the first template 21 and the second screw holes 33 on the upper left and right sides of the second template 31, together with the auxiliary… Corresponding to the third screw hole 44 of auxiliary component 4, eight bolts 1 arranged in a rectangular array are used to fix the auxiliary component 4, which is located at the middle of the outer side of the first mold component 2 and the second mold component 3, to achieve the overall assembly of the mold. This scheme ensures the stability and accuracy of the docking between the first mold component 2 and the second mold component 3 through the precise matching of the I-shaped slot 25 and the I-shaped insert 35. The design of the first circular groove 22, the first circular block 24, the second circular groove 32 and the second circular block 34 enables the cast concrete blocks to form a matching connection structure, which is convenient for rapid stacking and splicing. The four first screw holes 23 and the corresponding bolts 1 improve the firmness of the connection with the auxiliary component 4. The evenly distributed first circular grooves 22 ensure the uniformity of the concrete block connection structure, thereby improving the assembly efficiency, casting accuracy and construction adaptability of the mold blocks, which is conducive to the efficient implementation of modular construction.

[0034] It should be noted that this utility model is a modular concrete pouring mold for slope retaining wall construction. When this modular concrete pouring mold for slope retaining wall construction is in operation, firstly, the I-shaped insert 35 fixedly connected to the front end of the second template 31 in the second mold assembly 3 cooperates with the I-shaped slot 25 opened at the rear end of the first template 21 in the first mold assembly 2, achieving precise docking between the first template 21 and the second template 31. At this time, the front end face of the first template 21 and the rear end face of the second template 31 are in close contact. Simultaneously, multiple first circular grooves 22 at the front end of the first template 21 and multiple second circular blocks 34 at the rear end of the second template 31 correspond to each other, and the multiple second circular grooves 32 at the front end of the second template 31 also form a corresponding structure. Next, the auxiliary component 4 is placed at the middle of the top outer side of the docked first mold assembly 2 and second mold assembly 3, so that the connecting plate 41 passes through its third screw hole 44, the first screw hole 23 on the first template 21, and the second screw hole 33 on the second template 31, using eight bolts to hold the rods 1 respectively. The auxiliary component 4 is fixed to the first mold assembly 2 and the second mold assembly 3 by threaded connection of the bottom of the four bolts on the front side of the rod 1 and the bottom of the four bolts on the rear side of the rod 1. At this time, the arc-shaped base plate 42, the U-shaped plate 43 and the slot 45 form an auxiliary support and positioning structure. Then, concrete is poured into the space enclosed by the first mold assembly 2, the second mold assembly 3 and the auxiliary component 4. Since the poured concrete block will form a circular block corresponding to the first circular groove 22 on one side and a circular groove corresponding to the second circular groove 32 on the other side, it is convenient for subsequent stacking and splicing of concrete blocks. The arc-shaped base plate 42 has an arc structure that convexes downward at 120°, which makes it easy to push the mold out of the concrete block after the concrete solidifies. The design of the arc-shaped base plate 42 also facilitates the material pushing operation. After the pouring is completed, the bolts on the rod 1 are unscrewed, the auxiliary component 4 is separated, and then the first mold assembly 2 and the second mold assembly 3 are separated to complete one concrete pouring operation and realize modular construction.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
