Detailed implementation manners

[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 to 10 shown, this embodiment provides an adjustable mold for step wiring and cement pouring, including a bottom plate 1, side plates 2, tread plates 3 and brackets. The brackets include a middle frame 4 for supporting the area between the two ends of the lower surface of the bottom plate 1 and end frames 5 for supporting the two ends of the bottom plate 1. A side plate positioning assembly 6 for fixing the ends of the side plates 2 is provided on the end frames 5, and a suspension assembly 7 for suspending the tread plates 3 is provided between the two end frames 5.

[0032] The bottom plate 1 is supported by a bracket, then the tread plate 3 is suspended above the bottom plate 1 by a suspension assembly 7, and two side plates 2 are fixed on the upper surface of the bottom plate 1 by a side plate positioning assembly 6. The two side plates 2 clamp and fix the tread plate 3 from both sides, thus realizing the installation of the overall formwork. In the above formwork, the bottom plate 1, the side plates 2 and the tread plate 3 are in a closely attached and fixed state through the bracket, the side plate positioning assembly 6 and the suspension assembly 7, replacing the direct connection method with nails in the prior art, making it more convenient for the installation, disassembly and repeated use of the formwork. At the same time, the formwork will not be damaged, the operation efficiency can be improved, and it can adapt to the construction operations of stepped wiring cement pouring with different specifications.

[0033] In this embodiment, the middle frame body 4 includes a plurality of first brackets 4.1 distributed in sequence along the length direction of the bottom plate 1. The top of the first bracket 4.1 is provided with a first cross beam, and both sides of the top of the first cross beam are fixedly installed with first clamping blocks 4.2. A telescopic plate 8 supporting the lower surface of the bottom plate 1 is clamped between two adjacent first clamping blocks 4.2.

[0034] The end frame body 5 includes a second bracket 5.1. The top of the second bracket 5.1 is provided with a second cross beam. A second clamping block 5.2 is arranged on one side of the second cross beam facing its adjacent first cross beam, and the other end of the telescopic plate 8 between the first clamping block 4.2 and the second clamping block 5.2 is clamped with the second clamping block 5.2.

[0035] Both the first bracket 4.1 and the second bracket 5.1 include two columns and a tension rod connected between the bottoms of the two columns. Both the first cross beam and the second cross beam are arranged between the tops of the two columns.

[0036] During the erection of the bracket, the end frame body 5 is connected to the middle frame body 4 and adjacent middle frame bodies 4 by using the telescopic plate 8. At the same time, the distance between the end frame body 5 and the middle frame body 4 and adjacent middle frame bodies 4 is adjusted by the telescopic movement of the telescopic plate 8 to meet the installation requirements of formworks with different lengths. When installing the formwork, two rows of telescopic plates 8 support on both sides of the lower surface of the bottom plate 1, improving the support effect on the bottom plate 1 and further improving the overall stability of the formwork.

[0037] Specifically, the telescopic plate 8 includes a plate sleeve and a plate body. The plate sleeve is in a "C" - shaped structure, and telescopic chutes are arranged on the inner walls of both sides of the plate sleeve. Telescopic sliders matched with the telescopic chutes are arranged on both sides of the plate body. The thicknesses of the plate sleeve and the plate body are the same, so that the upper and lower surfaces of the plate sleeve and the plate body are flush, ensuring that the telescopic plate 8 has a larger support surface when supporting the bottom plate 1. The second clamping block 5.2 is in an overall "C" - shaped structure, one of its side edges is connected to the second cross beam. The first clamping block 4.2 includes an overall formed by two "C" - shaped structures, and the two "C" - shaped structures are symmetrically distributed on both sides of the first cross beam. Jacks for inserting the top ends of the "C" - shaped structures are opened at the opposite ends of the plate sleeve and the plate body.

[0038] The first clamping block 4.2 and the second clamping block 5.2 are both arranged with their openings facing upwards. The telescopic plate 8 is directly sleeved on the end of the U-shaped structure from top to bottom through the jacking holes to realize the clamping connection with the first clamping block 4.2 and the second clamping block 5.2. When the template is supported by the telescopic plate 8, the gravity of the template is applied to the telescopic plate 8, which can ensure that the telescopic plate 8 and the first clamping block 4.2 and the second clamping block 5.2 are stably maintained in the clamped state.

[0039] Further, in this embodiment, the first cross beam includes a first beam body 4.3 and a first beam sleeve 4.4, the second cross beam includes a second beam body 5.3 and a second beam sleeve 5.4. Both sides of the second beam body 5.3 are arranged in a threaded shape. Strip-shaped sliding grooves 9 are formed on the surfaces of the first beam body 4.3 and the second beam body 5.3. The outer surfaces of the two ends of the first beam body 4.3 and the second beam body 5.3 and the inner wall surface of the strip-shaped sliding groove 9 are located on the same circumferential surface. The first clamping block 4.2 and the second clamping block 5.2 are respectively fixedly installed on the first beam sleeve 4.4 and the second beam sleeve 5.4. Strip-shaped sliding blocks 10 that are matched with the strip-shaped sliding grooves 9 are arranged on the inner wall surfaces of the first beam sleeve 4.4 and the second beam sleeve 5.4. The second cross beam further includes clamping nuts 5.5 clamped at both ends of the first beam sleeve 4.4, and the clamping nuts 5.5 are in threaded cooperation with the first beam sleeve 4.4.

[0040] The first beam sleeve 4.4 can axially displace on the first beam body 4.3, and the second beam sleeve 5.4 can axially slide on the second beam body 5.3, that is, displace in the width direction of the template. The first beam sleeve 4.4 and the second beam sleeve 5.4 are connected through the telescopic plate 8. Therefore, when adjusting the positions of the first beam sleeve 4.4 and the second beam sleeve 5.4 according to the width of the template, directly rotate the clamping nut 5.5, and use the clamping nut 5.5 to axially push the position of the second beam sleeve 5.4 along the second beam body 5.3, then the positions of the first beam sleeve 4.4, the second beam sleeve 5.4 and the telescopic plate 8 as a whole in the width direction of the template can be realized. After the adjustment is completed, the second beam sleeve 5.4 can be locked by the two clamping nuts 5.5 at both ends of the second beam sleeve 5.4 to realize the position fixation.

[0041] The cooperation between the strip-shaped sliding block 10 and the strip-shaped sliding groove 9 can prevent the first beam sleeve 4.4 and the second beam sleeve 5.4 from rotating on the first beam body 4.3 and the second beam body 5.3 respectively, thereby improving the stability of the support for the template. At the same time, it is also more convenient for the assembly operation of the support.

[0042] At the top of the second beam sleeve 5.4, there is an end support plate 11 in an "L" shape, and the end support plate 11 supports on the end corners of the lower surface of the bottom plate 1. The end support plate 11 cooperates with the second beam sleeve 5.4 to be fixed on the first beam body 4.3 in the circumferential direction, so that while the end frame body 5 supports the bottom plate 1, it also clamps the bottom plate 1 from both ends in the length direction of the bottom plate 1, further improving the stability of the formwork. And the end plane of the bottom plate 1 further has a limiting effect on the second beam sleeve 5.4 in the circumferential direction, thereby improving the overall stability.

[0043] The side plate positioning assembly 6 includes a support plate 6.1. The bottom end of the support plate 6.1 supports on the end frame body 5. A bidirectional lead screw 6.2 is rotatably installed on the outer side surface of the support plate 6.1. At both ends of the bidirectional lead screw 6.2, there are side top plates 6.3 that squeeze the side plates 2 from the outside. By rotating the bidirectional lead screw 6.2 to make the two support plates 6.1 move relative to each other or move apart, it can be applicable to formworks of different widths. During the process of the lateral positioning component fixing the side plates 2, the two side top plates 6.3 respectively squeeze the two side plates 2 from the outside inwards. At this time, the two side plates 2 clamp and fix the tread plates 3. Furthermore, the alignment of all the tread plates 3 is realized, so that all the tread plates 3 are arranged neatly in the length direction of the bottom plate 1.

[0044] At both ends of the support plate 6.1, there are rod sleeves 12 sleeved slidably. The rod sleeves 12 are rotatably sleeved on the bidirectional lead screw 6.2. In the middle of the bidirectional lead screw 6.2, there is a height adjustment plate 13 rotatably sleeved. A height adjustment bolt 14 whose bottom end is rotatably supported on the end frame body 5 is threadedly inserted into the height adjustment plate 13. And the top end of the side top plate 6.3 is connected with a pressing plate 15 for pressing the side plate 2 from top to bottom.

[0045] By rotating the height adjustment bolt 14 to drive the height adjustment plate 13 to rise and fall, the height adjustment plate 13 drives the bidirectional lead screw 6.2 to rise and fall. At this time, the bidirectional lead screw 6.2 drives the side top plate 6.3 and the pressing plate 15 to rise and fall. Therefore, when the lateral positioning component fixes the side plates 2, the pressing plate 15 can press on the end of the side plate 2 from top to bottom, so that the side plate 2 and the bottom plate 1 are effectively attached. At the same time, by using the clamping effect of the tread plates 3 and the side top plates 6.3 on the side plates 2 inside and outside, it is ensured that the side plates 2 are stably in an upright state.

[0046] The suspension assembly 7 includes a suspension rod 7.1 and a suspension plate 7.2. Both ends of the suspension rod 7.1 are respectively connected with the top ends of the two support plates 6.1. The suspension plates 7.2 are arranged corresponding to the tread plates 3 one by one. The top end of the suspension plate 7.2 is connected to the suspension rod 7.1. The tread plates 3 are slidably connected to the side surface of the suspension plate 7.2 in the tread width direction.

[0047] Specifically, in this embodiment, a slide rail is provided on the side surface of the tread plate 3, and a slide plate sleeved inside the slide rail is fixedly provided on the suspension plate 7.2, so that the tread plate 3 can be displaced in the width direction of the formwork when it is suspended. In this way, combined with the fixing method of the side plate 2 by the lateral positioning member, during the process of the side top plate 6.3 squeezing the side plate 2 inward, the positions of all the tread plates 3 can be adjusted by using the two side plates 2, so that all the tread plates 3 are arranged neatly in the length direction of the formwork.

[0048] Two rows of tooth grooves 7.3 are symmetrically distributed on the surface of the suspension rod 7.1 and are sequentially distributed along the axial direction of the suspension rod 7.1. A ring sleeve 7.4 is fixedly installed at the top end of the suspension plate 7.2. Two groups of tooth blocks 7.5 engaged with the two rows of tooth grooves 7.3 are symmetrically arranged on the inner wall surface of the ring sleeve 7.4. A strip-shaped channel 7.6 for the tooth block 7.5 to displace along the axial direction of the suspension rod 7.1 is formed between the two rows of tooth grooves 7.3. The end of the suspension rod 7.1 is rotatably matched with the support plate 6.1.

[0049] By rotating the suspension rod 7.1, the tooth block 7.5 is located in the strip-shaped channel 7.6. At this time, the suspension plate 7.2 can be moved along the length direction of the suspension rod 7.1 to adjust the distance between two adjacent tread plates 3. After the distance between the tread plates 3 is adjusted, by rotating the suspension rod 7.1, the tooth block 7.5 enters the tooth groove 7.3 and engages with it, so that the tread plate 3 can be fixed in the length direction of the suspension rod 7. At the same time, after the tread plate 3 is clamped by the side plate 2, it is locked in the circumferential direction of the suspension rod 7.1 and will not swing.

[0050] The end frame 5 further includes third brackets 5.6 respectively sleeved on both ends of the suspension rod 7.1. The end parts of the first beam body 4.3, the second beam body 5.3 and the suspension rod 7.1 respectively pass through the first bracket 4.1, the second bracket 5.1 and the third bracket 5.6, and locking nuts 16 are threadedly sleeved on both ends of the first beam body 4.3, the second beam body 5.3 and the suspension rod 7.1. Through the opposite locking action of the locking nuts 16, the rotation of the suspension rod 7.1 can be prevented, and the effect of fixing the suspension rod 7.1 in the circumferential direction can be achieved.

[0051] A threaded telescopic rod group 17 is connected between the same-side ends of the first beam body 4.3 and the second beam body 5.3 and between the same-side ends of two adjacent first beam bodies 4.3. The locking nuts 16 on the first beam body 4.3 and the second beam body 5.3 are pressed against the outer side surfaces of the ends of the threaded telescopic rod group 17. The end frame body 5 is connected to the middle frame body 4 and two adjacent middle frame bodies 4 by using the threaded telescopic rod group 17, making the overall stability of the support stronger. At the same time, the threaded telescopic rod group 17 can meet the construction requirements of different spacings between the end frame body 5 and the middle frame body 4 and between two adjacent middle frame bodies 4 by adjusting its own length. In this embodiment, sleeves are provided at both ends of the threaded telescopic rod group 17. One sleeve is fixedly connected to one end of the threaded telescopic rod group 17, and the other sleeve is rotationally matched with the other end of the threaded telescopic rod group 17. The sleeves are used to sleeved on the ends of the first beam body 4.3 or the second beam body 5.3. After rotating the locking nuts 16 on the first beam body 4.3 and the second beam body 5.3, the sleeves are pressed against the first beam body 4.3 and the second beam body 5.3.

[0052] In summary, the adjustable mold for step wiring cement pouring provided in this embodiment can be applied to cement pouring construction operations of step lines with different lengths and widths. At the same time, the fixing operations of the bottom plate 1, the side plates 2 and the step plates 3 are convenient, and the overall mold has the effects of being convenient to assemble and disassemble, can be reused, and is convenient to transport after disassembly.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
