Description

Technical Field

[0001] The present invention relates to the technical field of pile position lofting construction in building construction, and particularly relates to a pile foundation positioning and line drawing device. Background Art

[0002] For traditional precast pile position lofting, the total station is used to measure and set the pile position axis, and the artificial tape measure is used to loft the pile position contour line at equal intervals. Generally, the artificial person relies on the pile position center point, and the tray device is used to manually hold the brush to rotate the round tray for lofting. Due to the uneven site and the difficulty in controlling the amount of lime scattered manually. The Chinese patent with the publication number CN219076037U discloses a set of simple molds for assisting in the positioning and line drawing of prestressed pipe piles. After using the total station to fix the points and insert the positioning steel bars, the protective steel pipe is sleeved on the positioning steel bars, and a support plate is installed on the outside of the protective steel pipe. The lime on the support plate falls from the hollow through the operation of the rake, leaving a ground mark. It can be well controlled for a flat concrete ground, but it is not easy to control for a loose ground. The above methods all require two people to cooperate for lofting, and the pile driver moves frequently during the process, with low accuracy, time-consuming and laborious. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a pile foundation positioning and line drawing device, which can effectively control the lofting accuracy, save the usage amount of lime, improve the construction efficiency of pile position lofting, reduce the construction cost, and create good economic benefits.

[0004] To achieve this technical purpose, the present invention adopts the following scheme: A pile foundation positioning and line drawing device includes an inner positioning barrel, an intermediate driving layer, and an outer fixed barrel. The outer fixed barrel is sleeved outside the inner positioning barrel, and there is a material storage space between the outer fixed barrel and the inner positioning barrel. The intermediate driving layer is placed in the material storage space, and the movement of the intermediate driving layer drives the material in the material storage space to fall.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses the sandwich material storage space to cooperate with the intermediate driving layer to control the lime falling amount, effectively controls the lofting accuracy, can also save the usage amount of lime, has a simple operation, improves the construction efficiency of pile position lofting, and reduces the construction cost.

[0006] The preferred scheme of the present invention is:

[0007] The inner positioning barrel includes an inner barrel body, a bracket, a laser verticality instrument, a bottom tray, and a vibrator. The inner barrel body is in a frustum shape. The inner side wall of the inner barrel body is fixedly connected to the outer edge of the bracket. A laser verticality instrument is fixed on the bracket, and the laser verticality instrument is located on the axis of the inner barrel body. The bottom tray is placed at the lower end of the inner barrel body. A vibrator is connected to the upper surface of the bottom tray. A through hole is opened at the center of the bottom tray, and the through hole is aligned with the pile center point position.

[0008] The intermediate drive layer includes a circular handle, an inner shaft, a first spring, a hollow rod, an arc rod, and a second spring. A number of inner shafts are evenly distributed on the circular handle. A first spring is sleeved in the middle of each inner shaft, and a hollow rod is sleeved outside the first spring; the lower end of the inner shaft is connected to the arc rod, and the arc rods form a circular ring structure for blocking materials through the second spring. The circular ring structure is located outside the lower end of the inner layer positioning barrel.

[0009] A limiting circular plate is fixed on the side wall of the inner shaft located inside the hollow rod. A first limiting ring is fixed inside the middle of the hollow rod, and a second limiting ring is arranged on the inner wall of the lower end of the hollow rod. The first spring is sleeved on the inner shaft below the limiting circular plate, and one end of the first spring abuts against the limiting circular plate, the limiting circular plate abuts against the lower side surface of the first limiting ring, and the other end of the first spring abuts against the second limiting ring.

[0010] Under normal conditions, the circular ring structure is located above the bottom tray, and the inner and outer sides of the circular ring structure are closely attached to the inner barrel body and the outer layer fixed barrel respectively; in the working state of drawing lines, when pressing the circular handle, the circular ring structure expands and moves down to the lower end of the bottom tray. At this time, a material discharge gap appears between the bottom tray, the circular ring structure, and the outer layer fixed barrel, and the material falls from the material discharge gap onto the construction base surface.

[0011] A cylindrical plate is fixedly connected to the inner side of the circular handle, and the lower edge of the cylindrical plate is inserted or spliced into the upper end of the inner barrel body.

[0012] The outer layer fixed barrel includes an outer barrel body, bolts, and a bottom support ring. The outer barrel body is a frustum-shaped structure with an inclination angle smaller than that of the inner barrel body. The bolts pass through the outer barrel body and the inner barrel body to connect the inner layer positioning barrel, the intermediate drive layer, and the outer layer fixed barrel; the lower end of the outer barrel body is connected to the bottom support ring, and the bottom support ring is sleeved outside the lower end of the intermediate drive layer to form an annular material discharge channel.

[0013] It further includes a top cover, and the top cover covers the outer layer fixed barrel.

[0014] The top cover includes a cover plate, a cover plate handle, a cover plate plug, and a limiting notch. The cover plate is an annular plate, and a limiting notch is opened in the inner circle of the cover plate corresponding to the position of the inner shaft. When placing the top cover, the cover plate moves from top to bottom so that the inner shaft is stuck in the limiting notch; a cover plate handle is fixed on the upper surface of the cover plate, and a cover plate plug is fixed on the outer edge of the lower surface of the cover plate. The cover plate plug is inserted into the upper port of the outer barrel body. Description of the Drawings

Detailed implementation manners

[0028] To fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific implementation manners, but the present invention is not limited thereto.

[0029] Such as Figure 1As shown in the figure, a pile foundation positioning and line drawing device provided by the present invention is composed of an inner layer positioning barrel 1, an intermediate driving layer 2, an outer layer fixing barrel 3, a top cover 4, etc. The outer layer fixing barrel 3 is sleeved outside the inner layer positioning barrel 1, and a material storage space is formed between the two. The intermediate driving layer 2 is placed in the material storage space. When the intermediate driving layer 2 moves, the lower end of the material storage space starts to discharge materials for lofting and line drawing.

[0030] As Figure 2 and Figure 3 shown in the figure, the inner layer positioning barrel 1 is composed of an inner barrel body 11, a support plate 13, a cross bracket 12, a laser vertical instrument 14, a vibrator 16, a bottom tray 15, etc. The inner barrel body 11 is a frustum-shaped barrel structure. The middle inner side wall of the inner barrel body 11 is fixedly connected to the cross bracket 12. A support plate 13 is fixed on the cross bracket 12, or the middle inner side wall of the inner barrel body 11 is directly fixedly connected to the support plate 13. A laser vertical instrument 14 is fixedly installed on the support plate 13. The lower end of the inner barrel body 11 is fixed on the upper surface of the bottom tray 15. A plurality of vibrators 16 are evenly distributed on the upper surface of the bottom tray 15 inside the inner barrel body 11. A through hole is opened at the center position of the bottom tray 15, and the through hole is directly opposite to the laser emission port of the laser vertical instrument 14.

[0031] As Figures 4 to 7 shown in the figure, the intermediate driving layer 2 is sleeved outside the inner barrel body 11. The intermediate driving layer 2 is composed of a circular ring handle 21, a connecting piece 22, an inner shaft 24, a first spring 26, a hollow rod 25, an arc rod 27, a second spring 28, etc. A plurality of connecting pieces 22 are evenly fixed on the circular ring handle 21. Each connecting piece 22 is respectively fixedly connected to an inner shaft 24. A limit circular plate 241 is fixed in the middle of each inner shaft 24. A first spring 26 is sleeved on the inner shaft below the limit circular plate 241. A hollow rod 25 is sleeved outside the first spring 26. A first limit ring 251 is fixed on the inner wall of the middle of the hollow rod 25. A second limit ring 252 is fixed on the inner wall of the lower end of the hollow rod 25. The upper surface of the limit circular plate 241 abuts against the lower surface of the first limit ring 251. The lower end of the first spring 26 abuts against the upper surface of the second limit ring 252, forming an elastic telescopic structure. The lower end of each inner shaft 24 is fixedly connected to an arc rod 27. The arc rods 27 are connected by a second spring 28. The arc rods 27 and the second spring 28 together form a circular ring structure for plugging or discharging materials. This circular ring structure is placed on the bottom tray 15 under normal conditions. Preferably, an elastic material or a telescopic spring cover is sleeved outside each second spring 28, and both ends of the spring cover are respectively connected to the arc rod 27. Preferably, a cylindrical plate 23 is fixedly connected to the lower end of the circular ring handle 21, and the lower edge of the cylindrical plate 23 is inserted into the upper port of the inner barrel body 11 to form a sealed inner cavity. The inclination angle of the inner shaft 24 is the same as the inclination angle of the side wall of the inner barrel body 11.

[0032] As Figure 8As shown in the figure, the outer fixed barrel 3 is composed of an outer barrel body 31, connecting bolts 32, a bottom support ring 33, etc. The outer barrel body 31 is a frustum-shaped cylindrical structure. The inclination angle of the side wall of the outer barrel body 31 (the angle between the normal line of the side wall and the horizontal line) is greater than the inclination angle of the inner barrel body 11, so that the material storage space formed between the inner barrel body 11 and the outer barrel body 31 gradually narrows from top to bottom. At the lower end, a ring structure formed by the arc-shaped rods 27 is exactly placed between the inner barrel body 11 and the outer barrel body 31, and the material will not fall. The lower end of the outer barrel body 31 is fixedly connected to the bottom support ring 33. The outer side wall of the bottom support ring 33 is a cylindrical barrel, and the side wall of the bottom support ring 33 is a conical barrel structure that gradually expands from top to bottom. The inclination angle of the conical barrel is the same as the inclination angle of the inner shaft 24. When the inner shaft 24 presses down the first spring 26 to drive the expansion and downward movement of the ring structure composed of the arc-shaped rods 27, the ring structure moves downward to between the bottom support ring 33 and the bottom tray 15. Since the outer side wall of the bottom tray 15 is cylindrical, a discharge gap is formed between the inner barrel body 11 and the outer barrel body 31, and the material falls through the discharge gap to form a mark.

[0033] Multiple groups of corresponding mounting holes are respectively provided on the side walls of the outer barrel body 31 and the inner barrel body 11. The connecting bolts 32 pass through the mounting holes of the inner and outer barrel bodies to connect the inner layer positioning barrel 1 and the outer layer fixed barrel 3.

[0034] As Figure 9 and Figure 10 shown in the figure, the upper end of the outer barrel body 31 is covered with a top cover 4. The top cover 4 is composed of a cover plate 41, a cover plate handle 42, a limit notch 44, a cover plate plug 43, etc. The cover plate 41 is a circular ring plate. A limit notch 44 corresponding to the position of the inner shaft 24 is provided in the inner circle of the cover plate 41. During installation, the cover plate 41 is lowered from above, and the inner shaft 24 is stuck in the limit notch 44. A cover plate handle 42 is fixed on the upper surface of the cover plate 41 for easy opening. A circular cover plate plug 43 is connected to the lower surface of the cover plate 41. The cover plate plug 43 is plugged into the upper port of the outer barrel body 31 to seal the material storage space and prevent the material from flying. Preferably, the cover plate plug 43 is made of silicone material.

[0035] Usage method:

[0036] Open the top cover 4, and put lime in the material storage space between the inner barrel body 11 and the outer barrel body 31, as Figure 11 shown in the figure. Install this device at the center of the pile position, turn on the laser verticality instrument 14 to ensure the verticality of the red heart point of the pile center, start the vibrator 16 to prevent the lime from getting damp and caking and being not easy to sprinkle. Press the ring handle 21, and the inner shaft 24 pushes the ring structure composed of the arc-shaped rods 27 to expand and move downward to between the bottom tray 15 and the bottom support ring 33 to form a dust falling port (i.e., the discharge gap). The lime slowly falls under the vibration of the vibrator 16 to form a mark, as Figure 12As shown. When stopped, release the ring handle 21, and the first spring 26 and the second spring 28 drive the ring structure to reset, closing the ash discharge port to complete the operation.

[0037] This device effectively solves the problems of inaccurate pile position lofting, low manual efficiency, waste of lime materials, etc., greatly improves the accuracy of pile position lofting, solves the common quality problems of pile body and pile position deviation, and provides technical guarantee for the construction of large-area precast piles. This device can be reused. After the auxiliary lofting at this point is completed, it is moved to the next point. The construction is convenient and simple, improving the overall construction quality and work efficiency.

[0038] Finally, it should be noted that the above-listed are only the preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and its equivalent technologies, they should be considered as within the protection scope of the present invention.
