Description

Technical Field

[0001] The invention relates to a pile foundation cap for building and a positioning method thereof. Background Art

[0002] The foundation form of high-rise building projects is mostly pile-cap foundation, including two-pile cap, three-pile cap, four-pile cap, five-pile cap, etc.

[0003] The unique shape and structure of the three-pile foundation caused great difficulties in the process of construction positioning and laying out. During the construction process, positioning is usually carried out according to the axis that has been laid out, and a steel ruler is used for distance measurement. A total of fourteen lengths need to be measured, and then nails are nailed at the end points, and the positions of the six sides can be released after being wrapped with thin wires. Then bricks are used to build brick membranes on the outside of the six sides. The inside of the brick membrane is the clearance size of the pile, that is, the size of the molded concrete after concrete pouring. After this step is completed, cement slurry should be applied on the inside of the brick membrane, and then waterproof membrane should be placed on the inside, and then cement slurry should be applied on the inside. In the implementation of this method, each three-pile foundation needs to go through the above steps, resulting in a waste of manpower.

[0004] Therefore, how to design a pile foundation cap for construction that can be positioned more quickly and accurately and a positioning method thereof is a problem that needs to be solved. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies of the above prior art and provide a pile foundation cap for construction and a positioning method thereof. By setting three detachable V-shaped frames, the positioning of the pile foundation is better assisted. By setting a permeable plate and a fixed plate, the steps of two plastering and pasting a waterproof cloth are reduced to only adding a waterproof cloth and then filling cement slurry, which saves steps and increases labor efficiency. The purpose of the present invention is achieved as follows:

[0006] On the one hand, the present invention provides a pile foundation pedestal for construction, comprising three V-shaped frames arranged in series, each of the V-shaped frames having a bending angle of 120 degrees, a first fixing hole being provided at the front end of each of the V-shaped frames, a second fixing hole being provided at the rear end of the V-shaped frames, a rotational connection between two adjacent V-shaped frames being inserted into the first fixing hole and the second fixing hole of the two V-shaped frames, the rotational connection being a circular ring with an opening at one end, a mounting surface being provided on the inner side of the rotational connection, a slope being provided in the second fixing hole, the mounting surface and the slope being fitted and fastened together with the rotation of the rotational connection; a fixing plate being provided on the upper part of the V-shaped frame, the bending angle of the fixing plate being 120 degrees, a permeation plate being provided on the outer side of the fixing plate in parallel, a plurality of permeation holes being provided on the permeation plate, and a waterproof plate being movably installed between the fixing plate and the permeation plate. With this design, it is only necessary to mark the vertical axis of the building to determine the position of the pile foundation, which reduces manpower and reduces errors. At the same time, the setting of the permeable plate and the fixed plate of the device reduces the construction steps of the brick membrane when building the brick membrane, further increasing the efficiency of the pile foundation construction.

[0007] Furthermore, in order to match the inner wall angles of the screw-on part and the fixing hole and reduce the friction between the screw-on part and the fixing hole, thereby making the screw-on smoother and avoiding installation difficulties or looseness, the curvature of the inner wall of the first fixing hole corresponds to the arc angle of the screw-on part.

[0008] Furthermore, the inclined surface and the center axis of the V-shaped frame are arranged at an angle of 30 degrees, so as to ensure that the V-shaped frame is easier to dock and more stable during the installation process, and at the same time has a limiting function.

[0009] Furthermore, the 45-degree opening arc can make the screw-on part easier to insert and fix, and the arc of the opening of the screw-on part is 45 degrees.

[0010] Furthermore, a handle is provided on the upper portion of the screw-on portion, and the handle design makes it easier for operators to screw on.

[0011] Furthermore, the penetration holes are circular in shape, and 30 of them are provided. The circular penetration holes can distribute cement slurry more evenly, ensuring that the entire surface of the penetration plate is well filled with cement slurry, thereby strengthening the bonding between the bricks and the penetration plate and the fixed plate.

[0012] Furthermore, the interval between the fixing plate and the penetration hole is 1-2 cm. This interval can form an appropriate space between the fixing plate and the penetration plate, so that the waterproof plate can be smoothly inserted and fit tightly, and also ensures that the cement slurry filling of the penetration hole is more uniform, while avoiding excessive intervals that may lead to poor waterproofing effects.

[0013] Furthermore, the rotating part is installed by buckling with the V-shaped frame through a clamp, and the clamp is a hollow tube with an opening and closing structure. With this design, the clamp can be directly sleeved on the rotating part, making the fixing of the rotating part more convenient.

[0014] On the other hand, the present invention provides a method for positioning a pile foundation pedestal for construction, which is used to implement a pile foundation pedestal for construction as described in claims 1-9, and includes the following steps: draw a midpoint on the upper side of a V-frame; adjust the position of the auxiliary angle steel so that one side of the angle steel is aligned with the vertical axis of the building, and let the extension line of one side of the angle steel coincide with the midpoint; splice three V-frames into a hexagon, and fix adjacent V-frames by a screw-on part; fix the screw-on part by inserting a clamp; lay bricks along the outer side of the permeable plate; insert the waterproof plate between the permeable plate and the fixed plate, and fit the waterproof plate tightly with the fixed plate; fill the gap between the permeable plate and the waterproof plate with cement slurry. This method reduces the steps of plastering twice and applying the waterproof cloth to only adding the waterproof cloth and then filling the cement slurry, saving steps and increasing labor efficiency.

[0015] Compared with the prior art, the invention has the following beneficial effects: by accurately calibrating the midpoint on the V-frame and aligning the vertical axis of the building with the auxiliary angle steel, the accurate positioning of the pile foundation cap can be ensured, thus avoiding the error that may be caused by manual measurement in the traditional method; the design of the screw connection part and the clamp simplifies the installation steps, making the splicing between the V-frames faster and more stable, greatly reducing the construction time and process, and significantly improving the construction efficiency;

[0016] By merging the traditional two-time plastering and waterproof cloth attaching processes into simple steps of filling cement slurry and waterproofing board, the complexity of construction and the required materials are reduced, thereby reducing the total project cost; the simplified process reduces the waiting and drying time during construction, thereby speeding up the construction period and improving overall work efficiency.

[0026] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0027] Please see Figure 1-7 On the one hand, an embodiment of the present invention proposes a pile foundation cap for construction, comprising three V-shaped frames 3 arranged in series, each of the V-shaped frames 3 having a bending angle of 120 degrees, a first fixing hole 6 being provided at the front end of each of the V-shaped frames 3, a second fixing hole 4 being provided at the rear end of the V-shaped frames 3, a rotary joint 8 between two adjacent V-shaped frames 3 being connected to the first fixing hole 6 and the second fixing hole 4 of the two V-shaped frames 3, the rotary joint 8 being a circular ring with an opening at one end, a mounting surface 10 being provided on the inner side of the rotary joint 8, a slope 12 being provided in the second fixing hole 4, the mounting surface 10 and the slope 12 being fitted and buckled after the rotary joint 8 rotates; a fixing plate 5 being installed on the upper part of the V-shaped frame 3, the bending angle of the fixing plate 5 being 120 degrees, a permeation plate 2 being installed in parallel on the outer side of the fixing plate 5, a plurality of permeation holes 1 being provided on the permeation plate 2, a waterproof plate 7 being movably installed between the fixing plate 5 and the permeation plate 2. With this design, it is only necessary to mark the vertical axis of the building to determine the position of the pile foundation, which reduces manpower and reduces errors. At the same time, the setting of the permeable plate 2 and the fixed plate 5 of the device reduces the construction steps of the brick membrane when building the brick membrane, further increasing the efficiency of pile foundation construction.

[0028] In this embodiment, by accurately calibrating the midpoint 9 on the V-frame 3 and using auxiliary angle steel to align the vertical axis of the building, the precise positioning of the pile foundation pedestal can be ensured, avoiding the errors that may be caused by manual measurement in the traditional method. The design of the screw-on part 8 and the clamp 13 simplifies the installation steps, making the splicing between the V-frames 3 faster and more stable, greatly reducing the construction time and process, and significantly improving the construction efficiency; by merging the traditional two-time plastering and waterproof cloth attachment processes into simple steps of filling cement slurry and waterproof board 7, the complexity of construction and the required materials are reduced, thereby reducing the total project cost; the simplified process reduces the waiting and drying time during construction, thereby speeding up the construction period and improving the overall work efficiency.

[0029] Specifically, the device includes three V-shaped frames 3 arranged in series, each of which has a bending angle of 120 degrees to form a hexagonal structure. The length of each side of the V-shaped frame 3 is 1 meter in this embodiment. A first fixing hole 6 is opened at the front end of each V-shaped frame 3, and a second fixing hole 4 is opened at the rear end of the V-shaped frame 3. The two holes are respectively arranged on the two sides of the V-shaped frame 3. The rotating part 8 is a circular connecting part with an open end, which is used to connect adjacent V-shaped frames 3 to ensure that they form a firm connection by rotation or buckling. The screw-on portion 8 makes the installation of the V-shaped frame 3 faster and more accurate, while avoiding the installation inconvenience or looseness caused by the variable angles in the traditional bolt connection method; the inner side of the screw-on portion 8 is provided with a mounting surface 10, the area of ​​which is 10 square centimeters, and the surface area of ​​the inclined surface 12 is 7 square centimeters in the second fixing hole 4. The mounting surface 10 and the inclined surface 12 are fitted and fastened and installed after the screw-on portion 8 rotates. This design makes the fixing between the V-shaped frames 3 faster, saves manpower, and ensures the accuracy of the connection. In addition, a permeation plate 2 is installed parallel to the outer side of the fixed plate 5, and the bottom of the permeation plate 2 is fixed to the V-shaped frame 3 by welding. The angle between the permeation plate 2 and the fixed plate 5 is the same as the angle of the V-shaped frame 3, both of which are 120 degrees. A plurality of permeation holes 1 are provided on the permeation plate 2, and a waterproof plate 7 is movably installed between the fixed plate 5 and the permeation plate 2. The waterproof plate 7 is an accessory component and can be installed only after all three V-shaped frames 3 are installed. The material of the waterproof plate 7 can be one of plastic, rubber or synthetic resin.

[0030] In one embodiment, the inner wall curvature of the first fixing hole 6 corresponds to the arc angle of the screw-on portion 8. This design can reduce the friction during screw-on, ensure a smoother screw-on process, and avoid installation difficulties or looseness problems caused by excessive friction.

[0031] In one embodiment, the inclined surface 12 is arranged at an angle of 30 degrees with the center axis of the V-shaped frame 3. This design ensures that the V-shaped frame 3 can be smoothly docked and fixed during the installation process, and also plays a certain limiting role, thereby avoiding the difficulty in aligning and inserting the screw-on portion 8 due to incorrect angles during the installation process.

[0032] In one embodiment, the arc of the opening of the screw-on portion 8 is 45 degrees. This design facilitates the screw-on portion 8 to enter the fixing hole and complete the locking. During installation, a more horizontal pressure is formed to make the V-shaped frames 3 fit tightly.

[0033] In one embodiment, a handle 11 is provided on the upper portion of the screw-on portion 8 to facilitate manual rotation by an operator during installation.

[0034] In one embodiment, the permeation hole 1 is circular in shape and is provided with 30 holes. The design of the permeation hole 1 can ensure that the cement slurry is evenly distributed on the permeation plate 2 to imitate the plastering effect in the prior art. In actual use, this structure can also enhance the bonding between the permeation plate 2 and the bricks of the external brick membrane.

[0035] In one embodiment, the interval between the fixing plate 5 and the penetration hole 1 is 1-2 cm. This design reserves enough space for the waterproof board 7 and cement slurry to further enhance the bonding between the penetration plate 2 and the bricks of the external brick membrane.

[0036] In one embodiment, the screw-on portion 8 is installed by snapping together with the V-shaped frame 3 through a clamp 13. The clamp 13 is a hollow tube with an opening and closing structure. The inner diameter of the hollow tube is the same as the outer diameter of the screw-on portion 8. A protrusion is provided on the inner wall of the hollow tube. A protrusion is also provided on the outer wall of the protruding portion of the screw-on portion 8 in the box after the installation is completed. After the clamp 13 wraps the screw-on portion 8 through the opening and closing structure, the protrusions are snapped together. At this time, the screw-on portion 8 is fixed between two adjacent V-shaped portions, thereby fixing the two adjacent V-shaped portions.

[0037] Please see Figure 8 On the other hand, an embodiment of the present invention further provides a method for positioning a pile foundation cap for a building, which is used to implement a pile foundation cap for a building as described in claims 1-9, characterized in that it comprises the following steps: a. using a measuring tool, such as a steel tape measure or a laser rangefinder, to accurately measure and mark a midpoint 9 on the top edge of the V-shaped frame 3, and the midpoint 9 will be used in subsequent steps to align and install auxiliary angle steels;

[0038] b. Adjust the position of the auxiliary angle steel so that one side of the angle steel is aligned with the vertical axis of the building, and the extension line of one side of the angle steel coincides with the midpoint 9; specifically, the angle steel is used as an auxiliary positioning tool. The angle steel has a right angle and can be aligned with the vertical axis of the building. One side of the angle steel is aligned with the vertical axis of the building, and it is ensured that the extension line of the angle steel coincides with the midpoint 9 drawn on the V-shaped frame 3. In this way, the center position of the pile foundation can be ensured to be consistent with the vertical axis of the building design, avoiding the later structural deviation;

[0039] c. Splice three V-shaped frames 3 into a hexagon, and fix adjacent V-shaped frames 3 by means of a screw connection 8; specifically, splice three V-shaped frames 3 into a hexagon according to design requirements, and the front end and the rear end of each V-shaped frame 3 are respectively provided with a fixing hole and a screw connection 8, and adjacent V-shaped frames 3 are firmly connected by means of the screw connection 8. During the installation process, the screw connection 8 is precisely inserted into the fixing hole of the V-shaped frame 3 and is tightly fixed, so that the connection between all V-shaped frames 3 is stable;

[0040] d. The fastener 13 is inserted into the rotating part 8 to fix it; specifically, after the rotating part 8 is connected to the V-shaped frame 3, the rotating part 8 is further fixed by the fastener 13. The fastener 13 adopts a hollow tube design with an opening and closing structure, which is convenient for installation and ensures that it cannot be easily loosened after connection. The installation method of the fastener 13 simplifies the process of traditional bolt or welding connection, making the entire construction process more efficient and the connection more secure;

[0041] e. Laying bricks along the outer side of the permeable plate 2; this step is a bricklaying membrane step in the general prior art, but this step is along the outer side of the permeable plate 2. Compared with the existing bricklaying membrane step, due to the permeable plate 2, it is convenient to align the bricks, and the efficiency and accuracy are improved;

[0042] f. Insert the waterproof plate 7 between the penetration plate 2 and the fixed plate 5, and fit the waterproof plate 7 and the fixed plate 5 tightly; ensure that the waterproof layer forms a complete sealing structure to prevent moisture from penetrating into the pile foundation cap when filling the cement slurry;

[0043] g. Fill the gap between the permeable plate 2 and the waterproof plate 7 with cement slurry. The cement slurry filling here is a substitute for applying cement slurry twice with a tool in the prior art. This method does not require a cement craftsman to complete the slurry coating step, thereby increasing efficiency.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
