Description

Technical Field

[0001] This utility model relates to the field of power and communication tower foundation construction technology, specifically to a simple installation device that can be adapted to various specifications of tower foundation anchor bolts. Background Technology

[0002] High-voltage power line towers are crucial facilities in modern power systems, providing overhead power lines and offering protection and support. Existing high-voltage power line towers typically have four sets of anchor bolts installed on their bases to secure the tower. These anchor bolts are generally arranged in a square pattern.

[0003] During the pouring of the tower foundation, the anchor bolts need to be accurately positioned. The industry commonly uses horizontal beams to position and fix the anchor bolts, which are then removed one by one after the concrete is poured. However, this process has significant drawbacks: the anchor bolts are easily displaced by external forces during construction, and the installation and dismantling of the beams require a large amount of manpower and resources, resulting in low construction efficiency. Meanwhile, traditional tower foundation construction relies on customized special molds, the specifications of which are limited by the bolt type, leading to material waste, high costs, and frequent mold changes that further affect construction efficiency. Currently, there is a lack of installation devices that combine versatility with compatibility with multiple bolt sizes, highlighting the urgent need for related technological improvements.

[0004] Therefore, it is of great significance to design a simple installation device that can be adapted to various specifications of tower foundation bolts. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a simple installation device that can be adapted to multiple specifications of tower foundation anchor bolts. This device should be able to assist in the installation of various specifications of anchor bolts and have the characteristics of simple structure and easy use.

[0006] The technical solution of this utility model is:

[0007] A simple installation device that can be adapted to multiple specifications of tower foundation anchor bolts, characterized in that: it includes a steel plate body and a pouring and vibration port and bolt holes set on the steel plate body;

[0008] The pouring and vibration port is located at the center of the steel plate body; the bolt holes include a number of first bolt holes, a number of second bolt holes, and a number of third bolt holes evenly arranged around the pouring and vibration port.

[0009] The distance between the first bolt hole and the pouring vibration port, the distance between the second bolt hole and the pouring vibration port, and the distance between the third bolt hole and the pouring vibration port increase sequentially.

[0010] The diameters of the first bolt hole, the second bolt hole, and the third bolt hole increase sequentially.

[0011] The main body of the steel plate is a Q345B low alloy structural steel plate with a thickness of 10-20mm, and the surface of the main body of the steel plate is provided with an anti-rust layer.

[0012] The beneficial effects of this utility model are:

[0013] 1. High versatility: This device can be adapted to at least three sizes of anchor bolts, meeting various construction needs and improving the versatility of the device;

[0014] 2. Convenient construction: The bolt holes are arranged in a matrix and combined with specification markings. The corresponding bolt hole diameter can be quickly selected through the markings, ensuring accurate positioning, reducing manual measurement errors, and improving installation efficiency by at least 50%.

[0015] 3. High stability: The matrix-style bolt hole layout ensures that the anchor bolts are subjected to uniform force, further improving the safety of the tower base structure. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 As shown, a simple installation device that can be adapted to various specifications of tower foundation anchor bolts includes a steel plate body 1.

[0022] The main body of the steel plate is square. During installation, the steel plate is placed on the top of the tower base and supported and fixed by the support bracket 7, and aligned with the center of the hole wall of the tower base. Select the corresponding hole diameter group according to the bolt specifications, insert the bolt into the hole and fix it with the nut. Use a level to check the verticality of the bolt to ensure that the verticality error is ≤1°.

[0023] The main body of the steel plate is made of low-alloy steel (Q345B), and the surface of the main body of the steel plate is provided with an anti-rust layer to improve the durability of the device. The thickness of the main body of the steel plate is 10-20mm, preferably 15mm.

[0024] The steel plate body has a pouring vibration inlet 1.1 and bolt holes. The pouring vibration inlet is located at the center of the steel plate body. The bolt holes include a first bolt hole 2.1, a second bolt hole 2.2, and a third bolt hole 2.3. The first bolt holes are evenly distributed around the pouring vibration inlet, the second bolt holes are evenly distributed around the pouring vibration inlet, and the third bolt holes are evenly distributed around the pouring vibration inlet. There are four of each type of bolt hole. The diameters of the first, second, and third bolt holes increase sequentially, and their diameter tolerances are all controlled within ±0.5mm.

[0025] Bolt holes of the same diameter are set as a group, and each group of bolt holes is arranged symmetrically about the center of the steel plate body to form a matrix layout, so that the anchor bolts 5 installed at any of the bolt hole positions in the group meet the symmetrical force requirements of the tower base.

[0026] The distance between the center of the second bolt hole and the center of the pouring vibration port is greater than the distance between the center of the first bolt hole and the center of the pouring vibration port. The distance between the center of the third bolt hole and the center of the pouring vibration port is greater than the distance between the center of the second bolt hole and the center of the pouring vibration port. The larger the bolt hole diameter, the farther away it is from the center of the steel plate body.

[0027] Specification markings and design parameters, including hole diameter, bolt type and design allowable load (e.g., "M20" "M24"), are also engraved near each bolt hole on the top surface of the steel plate body to facilitate matching with anchor bolts 5 of the same specification.

[0028] The method of using this utility model is as follows:

[0029] 1. Select appropriate anchor bolts according to the design parameters of the tower base, and select bolt holes on the main body of the steel plate that are compatible with the anchor bolts. Insert the anchor bolts into the bolt holes and screw in the nuts to fix them.

[0030] 2. For example Figure 2 As shown, support frame 7 is placed on top of the casting template of the tower base, and then the steel plate body with anchor bolts is placed flat on the support frame 7. One end of the hook of the anchor bolt extends downward into the casting template to avoid the anchor bolt contacting the reinforcing cage. At the same time, the center of the steel plate body is aligned with the center of the tower base and the verticality of the anchor bolt is checked with a level (ensuring verticality error ≤1°).

[0031] 3. Concrete is poured through the vibratory pouring nozzle;

[0032] 4. After the pouring is completed, unscrew the nuts and remove the main steel plate. The installation of the anchor bolts is now complete.

[0033] 5. Clean the main body of the steel plate and check all bolt holes. If there is no deformation in the holes, it can be reused.

[0034] This invention designs a tower foundation bolt installation device compatible with multiple specifications of anchor bolts. By integrating bolt holes of various specifications into a single steel plate, and supplementing it with markings and a symmetrical layout design, it achieves multiple uses from a single plate. It significantly reduces construction costs, improves installation efficiency, and has high versatility and stability, making it suitable for rapid construction of power and communication tower foundations.

[0035] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
