Description

Technical Field

[0001] The utility model relates to the technical field of concrete forming molds, in particular to an adjustable mold for precast concrete components. Background Technique

[0002] Concrete components refer to prefabricated concrete components that have been fabricated before being installed at the construction site. Generally common ones include precast concrete floor slabs, concrete box girders for bridges, precast concrete roof truss beams for industrial factories, culvert frames, precast concrete piles for ground treatment, etc. During the production process of concrete components, forming molds are required.

[0003] Chinese Patent (authorization announcement number: CN 219095433 U, authorization announcement date: May 30, 2023) proposed a mold for adjusting the forming of concrete components. This mold for adjusting the forming of concrete components enables the mold for forming concrete components to have better adjustability during use, so as to be adjusted according to concrete components of different sizes, reducing limitations and thus facilitating better practicality.

[0004] When adjusting the size in the above patent, the first strip-shaped template 1 is moved. Under the action of the chute 5, the first strip-shaped template 1 slides on the second strip-shaped template 2 to adjust the size of the interval formed by the first strip-shaped template 1 and the second strip-shaped template 2. Although the size can be adjusted, only two groups of the first strip-shaped templates 1 can be moved, and the distance between the two groups of the second strip-shaped templates 2 cannot be adjusted as needed. Furthermore, there are limitations in the adjustment during the adjustment of the length or width. To facilitate the respective adjustment of the width or length of the concrete, we propose an adjustable mold for precast concrete components. Content of the Utility Model

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution: an adjustable mold for precast concrete components, including four corner pieces 1 at the corners. Two first sliding sockets 8 are provided on the corner piece 1. Multiple side plate pieces 2 are surrounded between the four corner pieces 1. An insertion plate 11 is fixedly connected to the side plate piece 2. A second sliding socket 10 is provided on the side plate piece 2. The insertion plate 11 is inserted into the corresponding first sliding socket 8. A plug-in piece 9 is inserted between the corresponding first sliding socket 8 and the corresponding second sliding socket 10. The insertion plates 11 on adjacent side plate pieces 2 are inserted into the second sliding sockets 10 on adjacent side plate pieces 2. Two mounting plates 17 are fixedly connected to the corner piece 1. A bayonet 19 is provided on the mounting plate 17. A clamping piece 6 is commonly clamped on the two bayonets 19. Connecting telescopic rods 23 are fixedly connected between adjacent clamping pieces 6. A locking assembly is installed between the four clamping pieces 6.

[0029] This concrete component forming mold is composed of four groups of corner components 1, four groups of plug-in components 9, and several lateral side plate components 2 to form a forming mold for precast concrete slabs. When it is necessary to adjust the size of the forming mold for precast concrete slabs, the corresponding side plate components 2 can be added or reduced to adjust the size, and thus it is convenient to adjust the width or length of the concrete slab forming mold respectively. The first sliding socket 8, the second sliding socket 10, and the plug board 11 provided can facilitate the connection of adjacent side plate components 2 and the connection between the side plate components 2 and the corner components 1 respectively. After the corresponding side plate components 2 are added or reduced, the size of this mold can be fixed by the locking component.

[0030] The locking component includes a first handwheel 30. Transversely arranged first rotating rods 24 are rotatably penetrated through the clamping components 6 at the front and rear of the left part. The right end of the first rotating rod 24 is fixedly connected with a first lead screw 21. First threaded sleeves 22 are fixedly sleeved on the clamping components 6 at the front and rear of the right part. The first lead screw 21 is threadedly penetrated through the first threaded sleeve 22. The first handwheel 30 is fixedly connected to the first rotating rod 24 at the front of the left part. A first bevel gear 25 is fixedly sleeved on the outer surface of the first rotating rod 24. Longitudinally arranged first transmission rods 27 are rotatably arranged on the clamping components 6 at the front and rear of the left part. The end of the first transmission rod 27 is fixedly connected with a second bevel gear 26. The second bevel gear 26 meshes with the first bevel gear 25. A first transmission telescopic rod 29 is fixedly connected between the two first transmission rods 27.

[0031] When the first handwheel 30 is rotated, the front and rear first lead screws 21 can rotate synchronously under the transmission action of the first transmission telescopic rod 29. When the first lead screw 21 rotates, the clamping components 6 at the front and rear of the right side can move left or right simultaneously, and thus the front and rear side plate components 2 of this mold can be tightened and positioned.

[0032] Longitudinally arranged second rotating rods 16 are rotatably penetrated through the clamping components 6 on the left and right sides in the front. A second handwheel 31 is fixedly connected to the second rotating rod 16 on the left side in the front. The end of the second rotating rod 16 is fixedly connected with a second lead screw 33. Second threaded sleeves 32 are fixedly sleeved on the clamping components 6 on the left and right sides in the rear.

Transversely arranged second transmission rods 35 are rotatably penetrated through the clamping components 6 on the left and right sides in the front. The end of the second transmission rod 35 is fixedly connected with a fourth bevel gear 34. The fourth bevel gear 34 meshes with the third bevel gear 5. A second transmission telescopic rod 28 is fixedly connected between the two second transmission rods 35.

[0033] When turning the second handwheel 31, under the action of the second transmission telescopic rod 28, the second lead screws 33 on the left and right sides can rotate synchronously. When the second lead screws 33 rotate, the clamping members 6 on the left and right sides at the rear can move back and forth synchronously, and then the left and right side plate members 2 of this mold can be tightened and positioned. The connecting telescopic rod 23, the first transmission telescopic rod 27 and the second transmission telescopic rod 28 provided can each adapt to telescopic, and can affect the transmission and telescopic properties of the first lead screw 21 or the second lead screw 33.

[0034] Both groups of the first lead screws 21 are horizontally arranged.

[0035] Both groups of the second lead screws 33 are vertically arranged, and the second lead screws 33 are located below the first lead screws 21.

[0036] Multiple positioning columns 3 are fixedly connected to the top end of the corner member 1, and a number of positioning jacks 7 are opened at the bottom of the corner member 1. Through the positioning columns 3 and the provided positioning jacks 7, it is convenient to stack this mold.

[0037] Connecting plates 14 are fixedly connected to both the side plate member 2 and the plug-in member 9. A reinforcing member 15 is fixedly connected to the bottom of the connecting plate 14. The provided reinforcing member 15 can facilitate personnel to strike the reinforcing member 15, facilitating the separation of the side plate member 2.

[0038] A number of first through holes 12 are opened on the connecting plate 14, and a number of second through holes 18 are opened on the mounting plate 17. A stable insertion rod 4 is inserted between the corresponding first through holes 12 and the corresponding second through holes 18. After the size of this mold is fixed, the stable insertion rod 4 is inserted to increase the connection stability of this mold.

[0039] A first handle hole 13 is arranged on the connecting plate 14, and a second handle hole 20 is arranged on the mounting plate 17. The provided first handle hole 13 and second handle hole 20 can facilitate personnel to pull out the side plate member 2 or the corner member 1.

[0040] Working principle: This concrete member forming mold is formed by four groups of corner members 1, four groups of plug-in members 9 and several lateral side plate members 2 to form a forming mold for a precast concrete slab. When it is necessary to adjust the size of the forming mold for the precast concrete slab, the corresponding side plate members 2 can be increased or decreased to adjust the size, and then it is convenient to adjust the width or length of the concrete slab forming mold respectively. The provided first sliding socket 8, second sliding socket 10 and plug board 11 can facilitate the connection of adjacent side plate members 2, and the side plate members 2 and the corner members 1 respectively. After the corresponding side plate members 2 can be increased or decreased, the size of this mold can be fixed by the locking component;

[0041] When using the locking assembly, rotate the first handwheel 30 or the second handwheel 31. When rotating the first handwheel 30, the first lead screws 21 on the front and rear sides can be synchronously rotated under the driving action of the first driving telescopic rod 29. When the first lead screws 21 rotate, the clamping members 6 at the front and rear on the right side can move leftward or rightward simultaneously, thereby the front and rear side plates 2 of this mold can be tightened and positioned. When rotating the second handwheel 31, the second lead screws 33 on the left and right sides can be synchronously rotated under the action of the second driving telescopic rod 28. When the second lead screws 33 rotate, the clamping members 6 on the left and right sides at the rear can move forward and backward synchronously, thereby the left and right side plates 2 of this mold can be tightened and positioned. Among them, the connecting telescopic rod 23, the first driving telescopic rod 27 and the second driving telescopic rod 28 are each adaptable to expand and contract, which can affect the drivability of the first lead screw 21 or the second lead screw 33.
