Description

Technical Field

[0001] This invention relates to a building construction positioning device, specifically to an adjustable movable positioning device for a precast retaining wall. Background Technology

[0002] River channel construction refers to construction operations aimed at river management, improvement of river water environment, and ecological restoration. During river channel construction, scientific and reasonable planning and design, combined with actual site conditions, are necessary to ensure the smooth progress of the construction process and ultimately achieve the desired management effect. With the advancement of construction technology, precast components have been widely used in the building construction field. Specifically, when using precast retaining walls for construction in river channels, it is necessary to ensure the dimensional requirements of adjacent joints between precast retaining walls. That is, when laying precast retaining walls one by one, adjacent precast components need to be continuously moved and positioned to ensure the construction quality of subsequent waterproofing processes such as asphalt filling on the precast retaining walls. Currently, threaded tie rods are commonly used for positioning. However, due to the typically long length of rivers, the material turnover efficiency during construction is low, the time consumption is long, and the accuracy is relatively low. Long-distance continuous construction can easily lead to cumulative errors. Therefore, there is an urgent need for an adjustable and movable positioning device for precast retaining walls that is highly efficient and easy to operate, suitable for river channel construction.

[0004] The technical problem to be solved by the present invention is achieved through the following technical solution: The present invention discloses an adjustable movable positioning device for prefabricated retaining walls, used for the movable positioning of prefabricated retaining wall bodies laid laterally. It includes triangular columns, longitudinal tie rods, arc-shaped clamping components, bending and twisting brackets, and transverse tie rods. The triangular columns are attached to the front left and right sides and the rear left and right sides of the laid prefabricated retaining wall body. The triangular columns on the front left and right sides and the triangular columns on the rear left and right sides of the prefabricated retaining wall body are each connected by a longitudinal tie rod. The outer end of each longitudinal tie rod passes through and is fitted with an arc-shaped clamping component. A bending and twisting clamp is provided at the end face that contacts the triangular column. Both ends of the longitudinal tie rod are provided with longitudinal nuts for contacting and tightening the arc-shaped clamp assembly. Transverse tie rods are installed between the front and rear arc-shaped clamp assemblies on the outer sides of the triangular columns on the left and right sides of the precast retaining wall. The arc-shaped clamp assembly includes an arc-shaped ring plate body. The outer side of the front arc-shaped clamp assembly is provided with a free transverse nut for fixing and tightening the transverse tie rod. The outer side of the rear arc-shaped clamp assembly is provided with a self-spinning mechanism for adjusting and tightening the transverse tie rod. The transverse tie rod achieves the movement and positioning process through the rotation and quick release of the free transverse nut and the self-spinning mechanism.

[0005] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the cross section of the triangular column is an isosceles right triangle, the prefabricated retaining wall is a square hollow structure with an open top, and the two ends of the opposite faces of adjacent prefabricated retaining walls form V-shaped grooves by reserving chamfers. The right-angled surface of the triangular column is used to attach the V-shaped grooves of the adjacent prefabricated retaining walls.

[0006] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the triangular column is a hollow tube, and the upper and lower parts of the triangular column are provided with a pair of longitudinal pull holes for inserting the longitudinal pull rod.

[0007] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the bending and twisting clamp is used to receive the arc-shaped ring plate body. The bending and twisting clamp includes a plate and a plug. The plate has a rod hole in the middle for accommodating the longitudinal tie rod. The bottom of the plate has a rubber pad that contacts the triangular column. The plug is fixedly installed on the upper part of the plate. The plug has a slot for inserting the arc-shaped ring plate body. The plug has a reinforcing rib on the outside.

[0008] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the self-locking mechanism includes a fixed mounting platform, a locking disc, and a self-locking nut. The arc-shaped ring plate body is provided with a horizontal pull hole for accommodating the transverse pull rod. The fixed mounting platform is fixed on the outer side of the arc-shaped ring plate body. The locking disc is fixed on the outer periphery of the fixed mounting platform by screws. The fixed mounting platform and the locking disc form an annular groove. The inner end face of the self-locking nut is provided with a plurality of annularly arranged protruding heads. The self-locking nut can rotate freely by sliding in the annular groove through the protruding heads. A sealing plate is fixed to the outer end of the self-locking nut.

[0009] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the outer end of the fixed mounting platform is provided with a stepped surface, the outer end of the locking disc is provided with a locking ring plate, the locking disc forms a stepped groove at the inner end through the locking ring plate, and a ring groove with an L-shaped cross section is formed between the stepped surface of the fixed mounting platform and the stepped groove of the locking disc.

[0010] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the locking disc is provided with an outer support leg arranged in a ring around its outer periphery, and the outer support leg is used to contact the surface of the arc-shaped ring plate body.

[0011] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the two ends of the transverse tie rod are provided with threaded parts, and the length of the threaded parts is not longer than the difference between the total length of the transverse tie rod and the transverse length of a single prefabricated retaining wall.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) The present invention uses four triangular columns and orthogonal tie rods to adjust the errors caused by the production of prefabricated retaining walls. The space for adjustment is moved outward through the tie rods connected to the columns, and the orthogonal force is transmitted through the arc-shaped clamping plate assembly.

[0014] (2) This invention utilizes the two isosceles sides of the triangular column to ensure the flatness of the contact surface of adjacent precast retaining walls, ensuring that the construction joint meets the size requirements. Through mobility and adjustability, it ensures that the positioning of adjacent precast retaining walls is accurate, and the free end is easy to measure. It will not cause the accumulation of positioning errors due to the error in the construction of the retaining wall.

[0015] (3) The present invention uses an arc-shaped clamping plate assembly to set a self-spinning mechanism, which reduces the spiral length, improves disassembly efficiency, optimizes lateral force, and reduces the impact of spiral force on positioning dimensions. The nut does not need to be unscrewed at both ends, reducing the number of screwing times and making operation simple. Attached Figure Description

Detailed Implementation

[0023] like Figure 1-6 As shown, an adjustable movable positioning device for a prefabricated retaining wall according to the present invention is used for the movable positioning of a prefabricated retaining wall 6 laid in the transverse direction. It includes a triangular column 1, a longitudinal tie rod 2, an arc-shaped clamping plate assembly 3, a bending and twisting clamping platform 4, and a transverse tie rod 5. The triangular column 1 is attached to the left and right sides of the front part and the left and right sides of the rear part of the prefabricated retaining wall 6. Specifically, the cross-section of the triangular column 1 is an isosceles right triangle. The prefabricated retaining wall 6 is a square hollow structure with an open top. The two ends of the opposite faces of adjacent prefabricated retaining walls 6 form V-shaped grooves by pre-reserved chamfers. The right-angled surface of the triangular column 1 is used to attach the V-shaped grooves of adjacent prefabricated retaining walls 6. The triangular column 1 is a hollow tube. The upper and lower parts of the triangular column 1 are provided with a pair of longitudinal pull holes 11 for inserting the longitudinal tie rod 2.

[0024] The triangular columns 1 on the left and right sides of the front part and the triangular columns 1 on the left and right sides of the rear part of the prefabricated retaining wall 6 are each connected by a longitudinal tie rod 2. The outer end of the longitudinal tie rod 2 passes through and is fitted with an arc-shaped clamping plate assembly 3. The end face of the arc-shaped clamping plate assembly 3 that contacts the triangular column 1 is provided with a bending and twisting bracket 4. The bending and twisting bracket 4 is used to receive the arc-shaped ring plate body 31. The bending and twisting bracket 4 includes a platform 41 and an insert block 42. The platform 41 has a rod hole 411 in the middle for accommodating the longitudinal tie rod 2. The bottom of the platform 41 has a rubber pad 412 that contacts the triangular column 1. The insert block 42 is fixedly installed on the upper part of the platform 41. The insert block 42 has a slot 421 for inserting the arc-shaped ring plate body 31. The outer side of the insert block 42 is provided with a reinforcing rib 422.

[0025] The longitudinal tie rod 2 has longitudinal nuts 21 at both ends for contacting and tightening the arc-shaped clamping plate assembly 3. Transverse tie rods 5 are installed between the front and rear arc-shaped clamping plate assemblies 3 on the outer sides of the triangular pillars 1 on the left and right sides of the prefabricated retaining wall 6. Specifically, the transverse tie rods 5 have threaded portions at both ends. The length of the threaded portion is not longer than the difference between the total length of the transverse tie rod 5 and the transverse length of a single prefabricated retaining wall 6, thereby reducing the impact of redundant threaded structures on disassembly. The arc-shaped clamping plate assembly 3 includes an arc-shaped ring plate body 31. The outer side of the front arc-shaped clamping plate assembly 3 has a free transverse nut 51 for fixing and tightening the transverse tie rod 5. The outer side of the rear arc-shaped clamping plate assembly 3 has a self-spinning mechanism 7 for adjusting and tightening the transverse tie rod 5. The transverse tie rod 5 achieves its movement and positioning process through the engagement and quick release of the free transverse nut 51 and the self-spinning mechanism 7.

[0026] To improve disassembly efficiency, optimize lateral force, and effectively reduce the impact of helical length and helical force on positioning dimensions, the self-spinning mechanism 7 of this invention includes a fixed mounting plate 71, a locking disc 72, and a self-spinning locking nut 73. The arc-shaped ring plate body 31 is provided with a horizontal pull hole for accommodating the lateral pull rod 5. The diameter of the horizontal pull hole is larger than the outer diameter of the lateral pull rod 5. The fixed mounting plate 71 is fixed to the outside of the arc-shaped ring plate body 31. The locking disc 72 is fixed to the outer periphery of the fixed mounting plate 71 by locking screws 721. Outer support legs 723 are arranged in a ring around the outer periphery of the locking disc 72. The outer support legs 723 are used to contact the surface of the arc-shaped ring plate body 31. The fixed mounting plate 71 and the locking disc 72 form an annular groove. The outer end of the fixed mounting plate 71 has a stepped surface, and the outer end of the locking disc 72 has a locking ring plate 722. The locking disc 72 forms an inner stepped groove through the locking ring plate 722. An annular groove with an L-shaped cross-section on one side is formed between the stepped surface of the fixed mounting plate 71 and the stepped groove of the locking disc 72. The inner end face of the self-locking nut 73 has multiple annularly arranged protruding heads 731. The self-locking nut 73 can rotate freely by sliding in the annular groove through the protruding heads 731. A sealing plate 732 is fixed to the outer end of the self-locking nut 73.

[0027] In actual construction, firstly, triangular columns 1 are fabricated, and two pairs of pre-drilled holes are made on the triangular columns 1 to facilitate the installation of longitudinal tie rods 2. Next, four triangular columns are placed on the pre-cast retaining wall. The triangular columns 1 are then fixed longitudinally using the longitudinal tie rods 2. Arc-shaped clamping components 3 are then installed on the longitudinal tie rods 2 and the triangular columns. Each longitudinal tie rod 2 has the same arc-shaped clamping components 3. Then, the transverse tie rods 5 are installed. It can be set that the two arc-shaped clamping components 3 on the rear two sides each have a self-spinning mechanism 7, so that the two front... The arc-shaped clamp assembly 3 is fixed only by screwing in the free transverse nut 51. During installation, the self-locking nut 73 is turned until the rear end of the transverse tie rod 5 is pulled to the sealing plate 732. Then, the front end is tightened by screwing in the self-locking nut 73. The amount of the transverse tie rod 5 unscrewed at the self-locking nut 73 can be quickly measured, thereby improving positioning accuracy. When the transverse tie rod 5 is subjected to transverse force, it generates an inward bending and torsional moment on the arc-shaped ring plate body 31. The bending and torsional clamping platform 4 can transfer the force to the surface of the triangular column 1, reducing deformation and improving positioning accuracy. During disassembly, the self-locking nut 73 can be quickly loosened, and the other end can be pulled out directly, thereby reducing the screwing operation time and increasing construction efficiency many times over.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
