DETAILED DESCRIPTION

[0019] ​​​​​​The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 11 shown, the present invention provides a template for the top molding of a fence column, which is used for prefabricating the brick cap at the top of a fence column with a stepped cube structure. It includes a plurality of stepped templates 1 distributed in sequence along the height direction, and adjacent two templates 1 are arranged relatively. The smaller end of the template 1 at the bottommost is upward. The template 1 is divided into a first side part 1.1 and a second side part 1.2 along the central axis, and the first side part 1.1 and the second side part 1.2 achieve mold closing and mold opening through relative movement or opposite movement. The opposite ends of adjacent two templates 1 are docking ends 2, and a "U"-shaped docking frame 3 is arranged between adjacent two docking ends 2, and the three inner side surfaces of the docking frame 3 are flush with the three inner wall surfaces of the docking ends 2 respectively. A partition 4 adapted to its width is slidably arranged in the docking frame 3. The front end of the partition 4 is inserted between adjacent two docking ends 2. The upper and lower side surfaces of the docking frame 3 are respectively in contact with the opposite surfaces of adjacent two docking ends 2. The docking frame 3 pushes the front end of the docking frame 3 out of the docking ends 2 through forward displacement, and separates the two docking ends 2.

[0021] After mold closing, all the templates 1 form a complete cavity through the connection of the docking ends 2. Furthermore, the concrete can be poured into all the templates 1 at one time. The docking frame 3 is placed between the docking ends 2 of two templates 1, which can not only seal the three side surfaces of the docking ends 2, but also provide a stable space for the partition 4 to be inserted into the docking ends 2.

[0022] The partition 4 is inserted into the docking ends 2 through forward displacement. When the partition 4 pushes the front end of the docking frame 3 forward out of the range of the docking ends 2, the partition 4 can seal the docking ends 2 and separate the cavities of adjacent two templates 1, so that a prefabricated brick cap at the top of a fence column can be formed after the concrete in each template 1 cavity is formed.

[0023] Lifting sleeves 5 are fixedly installed at the front and rear ends on the sides of the first side part 1.1 and the second side part 1.2. A longitudinal rod 6 is穿设在升降套5内,且在左右方向位于同侧的两个纵向杆6的底端之间固定连接有滑座7,位于最下方隔板4的底部设置有底座8,且滑座7在左右方向能够位移地设置在底座8上,用于第一侧部分1.1和第二侧部分1.2的合模和开模。

[0024] It should be noted that there is an error in the description of the longitudinal rod 6 in the original text in line 18. I have made the translation according to the corrected content as much as possible. If there are other issues, please feel free to let me know.The longitudinal rod 6 and the limiting of the lifting sleeve 5 can make all the first side portions 1.1 and the second side portions 1.2 of the mold plate 1 in the aligned state. The relative movement or opposite movement between the first side portion 1.1 and the second side portion 1.2 is realized by the displacement of the sliding seat 7 on the base 8, thereby realizing the mold opening and closing of the mold plate 1. Specifically, in the embodiment, the lead screws are rotatably installed on the front and rear sides of the base 8, and the sliding seat 7 is threadedly sleeved on the lead screws.

[0025] The two sides of the docking end 2 extend in the docking direction and are provided with lateral limiting plates 9, and the docking frame 3 is limited in the width direction between the two lateral limiting plates 9. The lateral limiting plates 9 located on the left and right sides of the mold plate 1 can limit the position of the docking frame 3 in the left and right directions, so that the left and right inner wall surfaces of the docking frame 3 are always flush with the left and right inner wall surfaces of the docking end 2. When the docking frame 3 is displaced forward and backward, the docking frame 3 can be guided by the lateral limiting plates 9 and will not be offset relative to the mold plate 1.

[0026] The partition plate 4 includes a front end portion 4.1, a rear end portion 4.2, an upper plate body 4.3 and a lower plate body 4.4. The upper plate body 4.3 and the lower plate body 4.4 are oppositely distributed in the up-down direction, and the upper plate body 4.3 and the lower plate body 4.4 are arranged to be matched with the size of the inner cavity of the docking end 2. The upper plate body 4.3 and the lower plate body 4.4 are arranged to be able to be lifted between the front end portion 4.1 and the rear end portion 4.2. The two sides between the upper plate body 4.3 and the lower plate body 4.4 are provided with connecting plates 4.5, and the front end portion 4.1 and the rear end portion 4.2 are fixedly connected with the connecting plates 4.5. The partition plate 4 is provided with a lifting assembly for controlling the lifting of the upper plate body 4.3 and the lower plate body 4.4.

[0027] The connecting plate 4.5 fixedly connects the front end portion 4.1 and the rear end portion 4.2 as a whole, and the front and rear ends of the upper plate body 4.3 and the lower plate body 4.4 are tightly attached to the opposite surfaces of the front end portion 4.1 and the rear end portion 4.2, so that the upper and lower sides of the partition plate 4 form a relatively closed plane. In the initial state, the upper surfaces of the front end portion 4.1, the upper plate body 4.3 and the rear end portion 4.2 are located on the same plane, and the lower surfaces of the front end portion 4.1, the lower plate body 4.4 and the rear end portion 4.2 are located on the same plane, so that the partition plate 4 can close the rear end of the docking end 2, and then in the process of pouring concrete, the partition plate 4 cooperates with the docking frame 3 to close the four sides of the docking end 2.

[0028] The lifting adjusting assembly comprises a sleeve 10, two screw rods 11, a gear 12 and a rack 13, the sleeve 10 is rotatably installed on the connecting plate 4.5, the two screw rods 11 are threadedly installed at the two ends of the sleeve 10, the top end of the upper screw rod 11 and the bottom end of the lower screw rod 11 are fixedly connected with the upper plate body 4.3 and the lower plate body 4.4 respectively, the rack 13 is slidably installed on the connecting plate 4.5, the rack 13 is fixedly connected with a sleeve 14, the front end portion 4.1 and the rear end portion 4.2 are rotatably connected with a lead screw 15, the tail end of the lead screw 15 penetrates through the rear end portion 4.2, and the sleeve 14 is threadedly sleeved outside the lead screw 15. The rear end of the lead screw 15 is fixedly connected with a handle, and when the partition plate 4 is displaced to the most forward position, the front side of the handle abuts against the rear side of the template 1, so as to limit the maximum distance of the forward movement of the partition plate 4.

[0029] By rotating the lead screw 15 to drive the sleeve 14 to move forward and backward, the sleeve 14 can drive the rack 13 to move forward and backward, and then the rack 13 can drive the gear 12 to rotate forward and backward, so that the sleeve 10 is driven by the gear 12 to rotate forward and backward, and the screw rod 11 drives the upper plate body 4.3 and the lower plate body 4.4 to move relatively or oppositely.

[0030] After the partition plate 4 is inserted into the front side position in the docking end 2, the partition plate 4 pushes the docking frame 3 forward, so that the front end of the docking frame 3 is separated from the docking end 2, at this time, the upper plate body 4.3 and the lower plate body 4.4 are flush with the inner wall surface of the docking end 2 respectively.

[0031] Then, the lead screw 15 on the partition plate 4 between the two templates 1 with smaller ends is rotated from top to bottom in sequence, so that the upper plate body 4.3 and the lower plate body 4.4 move relatively, the upper plate body 4.3 is displaced downward to enter between the front end portion 4.1 and the rear end portion 4.2, at this time, the concrete in the upper template 1 will be lowered, so that the concrete in the upper template 1 after forming has an extension part from the bottom of the upper template 1. Similarly, the lower plate body 4.4 is displaced upward to enter between the front end portion 4.1 and the rear end portion 4.2, at this time, the lower plate body 4.4 is away from the top of the concrete in the lower template 1, so that a gap is formed between the lower template 1 and the partition plate 4. At this time, the partition plate 4 between the two templates 1 with larger ends remains in the initial state.

[0032] Further, after the concrete in the template 1 is formed, the bottom of the top brick cap of the enclosing wall column formed in the template 1 with the smaller end downward has an extension part extending from the bottom of the template 1, and the bottom of the brick cap is flush with the larger end of the template 1. The top of the top brick cap of the enclosing wall column formed in the template 1 with the smaller end upward is flush with the top of the template 1, and the bottom of the brick cap is flush with the template 1.

[0033] Before the formwork is removed, the lead screws 15 on each of the partitions 4 between the larger ends of the two formworks 1 are rotated in sequence in the forward direction from top to bottom, so that the upper plate bodies 4.3 and the lower plate bodies 4.4 on the partitions 4 move relative to each other, and at this time, the upper plate bodies 4.3 and the lower plate bodies 4.4 are separated from and spaced apart from the larger ends of the brick caps of the top ends of the wall columns.

[0034] The lead screws 15 on each of the partitions 4 between the smaller ends of the two formworks 1 are then rotated in sequence in the reverse direction, so that the upper plate bodies 4.3 and the lower plate bodies 4.4 on the partitions 4 move away from each other, and at this time, the upper plate bodies 4.3 move upward to push the brick caps of the top ends of the wall columns that are formed on the top ends of the wall columns, and the formed brick caps of the top ends of the wall columns are pushed upward along the height direction of the formwork 1 to the larger end of the formwork 1, so that the brick caps of the top ends of the wall columns with the smaller ends facing downward are separated from the formwork 1.

[0035] Then, all the partitions 4 and the abutting frames 3 are pulled out from the abutting end 2 in sequence from top to bottom, and when the topmost partition 4 and the abutting frame 3 are pulled out from the abutting end 2, the extended part at the bottom of the brick cap of the top end of the wall column with the smaller end facing downward in the topmost formwork 1 pushes down the top of the brick cap of the top end of the wall column with the smaller end facing upward in the second formwork 1, and the brick cap of the top end of the wall column with the smaller end facing upward in the second formwork 1 is displaced downward in the second formwork 1 by the pressure, so that the brick cap of the top end of the wall column with the smaller end facing upward is demolded from the second formwork 1. In this way, the brick caps of the top ends of the wall columns can be sequentially demolded from the corresponding formworks 1 when the formworks 1 are in the closed state. Furthermore, after demolding, all the brick caps of the top ends of the wall columns are in a stable stacked state and do not fall over, thereby improving safety. At the same time, after demolding is completed, the first side part 1.1 and the second side part 1.2 are separated, and the formwork is opened.

[0036] The partitions 4 are provided with two connecting plates 4.5, and each of the connecting plates 4.5 is provided with lifting assemblies on the front and rear sides. The partitions 4 are provided with a sliding frame 16, and the two sides of the sliding frame 16 are in sliding cooperation with the connecting plates 4.5. The rack 13 is fixedly installed on the outer side of the sliding frame 16, and the lead sleeve 14 is fixedly installed in the middle of the sliding frame 16.

[0037] Each of the partitions 4 is provided with four lifting assemblies, which support the four orientations of the upper plate body 4.3 and the lower plate body 4.4, thereby improving the stability and strength of the partitions 4 and further improving the forming effect of the brick caps of the top ends of the wall columns.

[0038] The tail end of the two sides of the docking frame 3 is provided with a limiting block 17 in cross-section in the shape of a horizontally placed "T" character, and the smaller end of the limiting block 17 is fixed to the inner side wall of the docking frame 3. The rear end portion 4.2 is provided with a through slot on both sides which is adapted to the limiting block 17, and when the upper plate body 4.3 and the lower plate body 4.4 are in the initial height, the limiting block 17 can pass between the upper plate body 4.3 and the lower plate body 4.4.

[0039] By setting the limiting block 17, the tail end of the front end portion 4.1 is in contact with the front end of the limiting block 17 in the initial state. In the process of inserting the partition plate 4 into the docking end 2, the limiting block 17 passes between the opposite ends of the upper plate body 4.3 and the lower plate body 4.4 until the rear end portion 4.2 passes over the limiting block 17, and the partition plate 4 is in the extreme position on the front side.

[0040] The front end portion 4.1 includes a sharp end portion and a rectangular portion which are distributed in front and back. The sharp end portion is in the shape of an isosceles trapezoid with the sharp end facing forward. In the adjacent two formworks 1, the top of the lower formwork 1 at the front end extends forward with a support plate 18, and when the rear end of the rectangular portion is flush with the inner wall surface of the front end of the docking end 2, the sharp end portion is located outside the docking end 2, and the front end of the docking frame 3 is supported by the support plate 18.

[0041] When the partition plate 4 moves forward to the front end extreme position, the sharp end portion is located outside the docking end 2, and the rectangular portion enters between the docking ends 2 to replace the front end portion 4.1 of the docking frame 3 to close and support the front end of the docking end 2. The front end of the docking frame 3 is supported by the support plate 18 after being ejected from the docking end 2, and in this process, the part of the excess concrete between the front end portion 4.1 and the front end of the docking frame 3 will be ejected. By setting the sharp end portion, the amount of concrete ejected can be reduced, and the loss of concrete can be reduced.

[0042] When there is residual concrete between the front end portion 4.1 and the front end of the docking frame 3, the docking frame 3 can be continuously pulled forward so that the front end of the docking frame 3 moves to the front side of the support plate 18 and is suspended, and then the front end portion 4.1 and the docking frame 3 can be directly flushed to remove the residual concrete. After flushing, the docking frame 3 can be pushed back onto the support plate 18.

[0043] The bottom of the front end part 4.1 between the smaller ends of the two templates 1 is provided with an overflow cavity 19, the front end of the overflow cavity 19 extends into the pointed end part, the rear end of the overflow cavity 19 penetrates the rectangular part, the bottom of the overflow cavity 19 is provided with a water inlet 20, the water inlet 20 is provided with a baffle 21 matched with the shape of the bottom of the pointed end part, the top of the baffle 21 is uniformly fixedly provided with a fixed plate 22, the tail end of the fixed plate 22 extends out of the rear end of the overflow cavity 19 and is fixedly connected with a lower plate body 4.4, the top of the front side surface of the lower plate body 4.4 and the bottom of the rear side surface of the rectangular part are uniformly provided with a first recess 23 and a second recess 24 which are oppositely open, when the lower plate body 4.4 rises to the highest position, the first recess 23 and the second recess 24 are cross-distributed in the height direction, and the overflow cavity 19 is communicated with the cavity of the docking end 2.

[0044] When the partition plate 4 moves to the front end limit position, the inclined surface bottom of the pointed end part, the inner wall surface of the front end of the docking frame 3 and the support plate 18 can form a closed area. When water flow is added to the area, the area can achieve a certain water locking effect.

[0045] After the upper plate body 4.3 and the lower plate body 4.4 in the partition plate 4 between the smaller ends of the two templates 1 relatively move, the first recess 23 and the second recess 24 communicate the cavity of the docking end 2 with the overflow cavity 19. When curing the concrete, water flow can be added to the water locking area corresponding to the smaller ends between the two templates 1, and after the height of the water flow exceeds the water inlet 20, the water flow can pass through the gap between the top of the baffle 21 and the fixed plate 22, and then flow through the second recess 24 and the first recess 23 into the docking end 2. At this time, the water flow mainly enters the two templates 1 opposite to the smaller ends, and the water flow can evaporate and transfer along the gap between all the templates 1, so as to achieve better curing effect of the concrete.

[0046] The application provides a construction method for wall column top modeling prefabrication by using the above-mentioned wall column top modeling template. Step one, uniformly brushing release agent on the inner wall surfaces of the first side part 1.1 and the second side part 1.2 and the upper and lower sides of the partition plate 4; Step two, relatively displacing the first side part 1.1 and the second side part 1.2 to perform mold closing; Step three, placing the docking frame 3 and the partition plate 4 between the docking ends 2 of the two templates 1, and making the three inner side surfaces of the docking frame 3 flush with the three inner wall surfaces of the docking ends 2, and making the front end of the partition plate 4 inside the docking ends 2, so that the two templates 1 form a continuous cavity through the docking ends 2; Step four, pouring concrete from the top end of the template 1 at the top to make the concrete fill all the templates 1; Step five, sequentially push each partition plate 4 from bottom to top, and make the partition plate 4 push the front end of the docking frame 3 out of the docking end 2, so that the partition plate 4 separates the cavities of the two formworks 1; Step six, carry out concrete curing operation, and carry out formwork opening operation after the concrete reaches the formwork removal standard.

[0047] In summary, the application can cast multiple prefabricated fence column top brick hats at a time, compared with the existing technology which adopts the way of casting one by one, which greatly improves the construction efficiency. All the brick hats are in a stable stacking state after forming, which is convenient for centralized transfer and storage. Direct demolding operation in the formwork 1 can improve stability and safety, and prevent tilting.
