[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0023] A pad stone template that is easy to adjust and construct, such as Figures 1 to 3 As shown, it includes a template body 5 and a positioning tooling arranged above the template body 5; the positioning tooling includes a fixed frame arranged on the template body 5, a movable beam 3 arranged on the fixed frame, and an embedded pipe 4 arranged on the movable beam 3, and the fixed frame is detachably installed on the template body 5; the movable beam 3 is horizontally slidably installed on the fixed frame, and the embedded pipe 4 is horizontally slidably installed on the movable beam 3, the sliding direction of the embedded pipe 4 is perpendicular to the sliding direction of the movable beam 3, and the movable beam 3 is provided with an adjustment component for adjusting the height of the embedded pipe 4.

[0024] Exemplarily, the template body 5 can adopt the existing spliced ​​plastic-steel template. The assembled plastic-steel template is generally connected by plugging and pulling. It is composed of a plastic-steel template and a chamfer for connecting the plastic-steel template. It can be adjusted and assembled according to pads of different sizes. Compared with other forms of templates, it has the advantages of convenient construction, low cost, and easy adjustment. In addition, those skilled in the art can also select a suitable template body 5 according to actual needs, which will not be repeated here.

[0025] In actual application, the fixed frame can be fixed on the template body 5 by bolts. The fixed frame can be made by welding angle steels, which is beneficial to improve the structural strength and stability of the fixed frame, while reducing the weight of the fixed frame, making it easier for construction workers to install the fixed frame.

[0026] Preferably, the fixed frame includes an outer frame 1 and a longitudinal beam 2 arranged in the outer frame 1, wherein at least two longitudinal beams 2 are arranged at intervals, and there is a receiving gap between two adjacent longitudinal beams 2 for accommodating the movable crossbeam 3 and the embedded pipe 4, and the left and right ends of the movable crossbeam 3 are respectively slidably mounted on the two longitudinal beams 2. Exemplarily, the outer frame 1 is an annular structure, and the longitudinal beam 2 is fixed on the outer frame 1. By arranging at least two longitudinal beams 2, the structural strength of the fixed frame as a whole can be further improved, and by installing the movable crossbeam 3 on the longitudinal beam 2, a tic-tac-toe structure can be formed in the outer frame 1, thereby improving the stability of the connection between the movable crossbeam 3 and the outer frame 1. At the same time, the end of the movable crossbeam 3 can be prevented from extending out of the outer frame 1, which is convenient for construction personnel to adjust the movable crossbeam 3 within the range of the outer frame 1, reducing the difficulty of adjustment and construction, and the safety is also higher. In addition, the outer frame 1 can also play a certain protective role on the movable crossbeam 3, reducing the possibility of damage to the end of the movable crossbeam 3 during construction.

[0027] Preferably, both left and right ends of the movable crossbeam 3 are slidably mounted on the fixed frame through the sliding seat 8, and there is an operating gap 13 between the movable crossbeam 3 and the fixed frame for facilitating the operation of the adjustment component. Exemplarily, two sliding seats 8 are provided corresponding to the left and right ends of the movable crossbeam 3, and each sliding seat 8 is fixed on the movable crossbeam 3. By slidingly mounting the movable crossbeam 3 using the sliding seat 8, an operating gap 13 can be formed between the movable crossbeam 3 and the fixed frame, which is not only convenient for construction personnel to adjust the position of the movable crossbeam 3 using the operating gap 13, but also reserves space for construction personnel to operate the adjustment component, which is conducive to reducing the difficulty of adjusting the position of the embedded pipe 4 and improving the convenience of adjusting the cushion stone template during the construction process.

[0028] Preferably, the sliding seat 8 is slidably installed on the fixed frame through a slider 12, and a sliding rod 16 is provided on the slider 12. An elongated hole 10 slidably matched with the sliding rod 16 is provided on the longitudinal beam 2 of the fixed frame, and the length direction of the elongated hole 10 is the same as the sliding direction of the sliding seat 8; an assembly hole matching with the sliding rod 16 is provided on the sliding seat 8, one end of the sliding rod 16 is arranged on the slider 12, and the other end passes through the elongated hole 10 and the assembly hole in sequence, and a detachable limiter 11 is provided on the end of the sliding rod 16 passing through the assembly hole.

[0029] For example, the slide bar 16 is fixed on the slider 12, the limiting member 11 can be a limiting nut, and the slide bar 16 is provided with an external thread that matches the limiting nut, and the limiting member 11 can play a good limiting role on the slide bar 16. At the same time, the position corresponding to the long hole 10 on the slide bar 16 can be provided with an arc surface or a smooth surface to reduce the friction between the slide bar 16 and the inner wall of the long hole 10, so as to facilitate the construction personnel to adjust the slide seat 8 and the movable crossbeam 3 on the slide seat 8, which is conducive to reducing the difficulty of sliding adjustment of the movable crossbeam 3.

[0030] In actual application, a pair of threaded rods 17 are provided on the slider 12 at positions corresponding to the left and right sides of the slide rod 16, and the sliding seat 8 is provided with mounting holes that cooperate with the threaded rods 17. One end of each of the threaded rods 17 is set on the slider 12, and the other end passes through the long hole 10 and the mounting hole in turn. A fixing nut 6 is provided at one end of the threaded rod 17 passing through the mounting hole.

[0031] Exemplarily, the fixing nut 6 can be a locking nut, and the threaded rods 17 are fixed on the slider 12, and two mounting holes are provided corresponding to the threaded rods 17. By providing two threaded rods 17 on the slider 12 corresponding to the left and right sides of the slider 16, and installing the fixing nut 6 above the threaded rod 17, the two fixing nuts 6 are used in conjunction with the threaded rod 17 to limit the sliding seat 8, which is beneficial to improving the stability of the sliding seat 8 after the adjustment is completed, ensuring that the movable crossbeam 3 and the embedded pipe 4 on the movable crossbeam 3 remain stable during the construction process, thereby improving the construction accuracy. Moreover, by providing the fixing nut 6 above the sliding seat 8, it is also convenient for construction personnel to screw the fixing nut 6 from above, further reducing the construction difficulty when the construction personnel adjust or fix the sliding seat 8.

[0032] Preferably, an elastic element 15 is provided on the slide bar 16 at a position corresponding to the position between the stopper 11 and the slide seat 8, and one end of the elastic element 15 abuts the slide seat 8, and the other end abuts the stopper 11. Exemplarily, the elastic element 15 is a compression spring, and the compression spring is sleeved on the slide bar 16.

[0033] In actual application, by setting an elastic element 15 at a position between the corresponding limit piece 11 and the sliding seat 8 on the sliding rod 16, when the construction personnel loosen or remove the fixing nut 6, the elastic element 15 can overcome the gravity of the slider 12 under the action of the reset elastic force, thereby maintaining stability or slightly moving downward (after maintaining stability or slightly moving downward, it is not easy to generate friction between the fixing nut 6 and the slider 12), ensuring that the fixing nut 6 can completely disengage from the sliding seat 8 during the movement of the sliding seat 8, thereby reducing the influence of the friction between the fixing nut 6 and the sliding seat 8 on the movement of the sliding seat 8, avoiding the fixing nut 6 from causing obstruction to the moving sliding seat 8, and facilitating the construction personnel to move the sliding seat 8 to adjust the movable beam 3, which is conducive to further reducing the difficulty of moving and adjusting the movable beam 3 and improving the movement and adjustment accuracy of the movable beam 3.

[0034] Optionally, in order to reduce weight, the sliding seat 8 and the movable crossbeam 3 can both be made of square steel pipes, the upper part of the sliding seat 8 can be welded and fixed on the movable crossbeam 3, and the lower part can be welded to a steel plate to form a stable inverted T-shaped structural member, which is conducive to improving the structural strength of the sliding seat 8 and ensuring the stability of the sliding seat 8 during the movement along the longitudinal beam 2. Among them, the mounting holes can be set on the steel plate, and the mounting holes are set one by one with the threaded rods 17.

[0035] Preferably, the adjustment assembly includes an adjustment bolt 7, the movable crossbeam 3 is provided with a strip hole 9 that is slidably matched with the adjustment bolt 7, one end of the adjustment bolt 7 that passes through the strip hole 9 is connected to the embedded pipe 4, and the adjustment bolt 7 is provided with an adjustment nut 14 at positions corresponding to the upper and lower positions of the movable crossbeam 3. Exemplarily, two adjustment nuts 14 are provided corresponding to the upper and lower positions of the movable crossbeam 3, and by using two adjustment nuts 14 to cooperate with the movable crossbeam 3, the stability limit of the adjustment bolt 7 on the movable crossbeam 3 can be achieved, thereby ensuring the stability of the embedded pipe 4 during the construction process.

[0036] In actual application, the adjusting bolt 7 and the embedded pipe 4 can be connected by a thread. Technical personnel in this field can also choose other ways to connect the adjusting bolt 7 and the embedded pipe 4 according to actual needs to achieve a stable connection between the two and ensure that the embedded pipe 4 can remain stable under the limit of the adjusting bolt 7 during the construction process. It will not be repeated here.

[0037] By using the adjusting bolts 7 to install the embedded pipe 4, the construction personnel can not only adjust the position of the embedded pipe 4 by horizontal sliding by loosening the adjusting nut 14 below, but also adjust the height of the embedded pipe 4 by adjusting the positions of the upper and lower adjusting nuts 14, thereby further improving the flexibility of adjusting the embedded pipe 4 during the construction process and improving the applicability of this stone pad template to different construction requirements.

[0038] Specifically, this kind of pad stone template can be constructed according to the following steps:

[0039] Step 1: Assemble and install the template; assemble the plastic steel pad stone template according to the design size of the pad stone to obtain the template body, and then install the template body. The template body is fixed on the pier top to ensure the accurate position of the template body.

[0040] Step 2: Assemble the fixed frame; weld L40*4 galvanized angle steel into a fixed frame, symmetrically open 6 holes with a diameter of 18mm on the angle steels on both sides of the fixed frame, and fix them with bolts and plastic steel templates, then symmetrically open 4 long holes with a width of 12mm and a length of 336mm on the angle steel (i.e. longitudinal beam) inside the fixed frame for installing movable crossbeams.

[0041] Step 3: Assemble the movable beams. The number of movable beams can be adjusted according to needs. Process the movable beams in advance according to the required size, and then open two strip holes with a width of 18mm and a length of 180mm on the two movable beams to adjust the position of the embedded pipes. The movable beams are slidably installed on the longitudinal beams in the fixed frame through the sliding seat.

[0042] Step 4: Fix the embedded pipe to the movable crossbeam by adjusting bolts and nuts, adjust the plane position of the embedded pipe along the long holes on the longitudinal beam and the strip holes on the movable crossbeam, and adjust the depth of the embedded pipe by adjusting nuts.

[0043] This type of pad stone template adopts a splicing structure, with fast assembly and erection speed, accurate positioning of embedded holes, high construction efficiency, high quality, light materials, and convenient turnover and transportation. It can effectively solve the problem of uneven pouring of the pier body top often encountered in conventional construction. By using this pad stone template, the depth of the embedded holes of the pad stone in the later stage can be adjusted according to the needs of the site to adjust the height of the embedded pipe, which is very convenient to operate and improves construction efficiency. At the same time, by using this pad stone template, the cost of secondary processing such as milling holes and grinding in the later stage can also be avoided, saving the amount of grouting materials and saving construction costs.

[0044] The present invention provides a stone cushion template that is easy to adjust and construct, and has the advantages of simple structure, easy adjustment and use, high applicability, and good structural stability after adjustment. By arranging a positioning tool on the template body, construction personnel can adjust the movable crossbeam and embedded pipe on the positioning tool by horizontal sliding to achieve the adjustment of the position of the embedded pipe on the horizontal plane. At the same time, construction personnel can also use the adjustment component to adjust the height of the embedded pipe to better adapt to different construction needs. The operation is simple and convenient, which reduces the operating difficulty of construction personnel and is conducive to improving construction efficiency.
