Description

Technical Field

[0001] The present invention relates to the field of building materials, and in particular to a quick-install anchor bolt positioning and inspection combined connection device. Background Art

[0002] During the construction process of anchor bolt positioning, a common method is to use a positioning steel plate with the same cross-section as the column base (with pre-set bolt positioning holes) to assist in positioning. The common method for anchor bolt positioning verification is for surveyors to use measuring instruments (theodolite, total station, level, and tower ruler) to measure the verticality and elevation of each anchor bolt, and to use a steel tape measure to measure the deviation from the axis. Conventional anchor bolt positioning steel plates are highly adaptable and difficult to use for positioning and installing anchor bolt assemblies at column bases of different sizes. The positioning plates are also relatively thin, making them less suitable for use in steel structure processing after modification, resulting in poor turnover and low material utilization. While positioning steel plates are used in the anchor bolt verification process after concrete pouring to simplify manual measurement steps and reduce bolt assembly measurement time, existing positioning steel plates can only be inserted from directly above the bolt assembly. If individual bolts are misaligned beyond the positioning hole diameter, the entire positioning steel plate becomes unusable. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a quick-install anchor bolt positioning and inspection combined connection device. A quick-install anchor bolt positioning and inspection combined connection device includes a positioning plate located at a corner point and a connecting plate for connecting adjacent positioning plates; the positioning plate includes a positioning mother plate and a positioning sub-plate hinged to each other, the positioning mother plate and the positioning sub-plate cooperate with each other to form an anchor bolt positioning hole, and the connecting plate is used to connect two adjacent positioning mother plates.

[0004] The positioning plates and the connecting plates form a frame structure, which saves materials and has various sizes and shapes, making it easy to use in modular construction.

[0005] Preferably, the combined connection device further comprises an auxiliary positioning cylinder, and at least one set of fastening screws are symmetrically mounted on the side surface of the auxiliary positioning cylinder.

[0006] Preferably, the positioning mother plate is provided with a first notch opening outward, and the positioning sub-plate is provided with a second notch opening inward, and the first notch and the second notch cooperate with each other to form an anchor bolt positioning hole.

[0007] Preferably, the connecting plates are arranged in pairs in a plurality of groups, and the connecting plates in the same group have the same length.

[0008] Preferably, the positioning motherboard is provided with a plurality of connection holes along its extension direction.

[0009] Preferably, the positioning motherboards are divided into two categories, including corner positioning motherboards and middle positioning motherboards. The corner positioning motherboards are C-shaped structures symmetrically arranged on both sides of the first notch.

[0010] Preferably, the central positioning motherboard is a special-shaped structure with asymmetric sides of the notch.

[0011] Preferably, the positioning motherboard and the connecting plate are connected to form a frame structure with a hollow interior.

[0012] Preferably, the positioning motherboard and the connecting plate are detachably connected via a fastening device.

[0013] The beneficial effects of the present invention are: 1. The device disassembles a steel plate into three parts: a positioning mother plate, a positioning sub-plate and a connecting plate. Each component plate is designed and processed separately, retaining only the functional properties of the conventional positioning steel plate and replacing the positioning plate surface with a positioning frame, which greatly reduces material consumption and improves material utilization.

[0014] 2. The assembly parts are modularized, and different aperture positioning mother and daughter plates and different length connecting plates are combined into a quick-install device to achieve the positioning and inspection of different column foot anchor bolt groups. The quick-install device has high turnover.

[0015] 3. The positioning mother and daughter plates can be opened and closed, supporting rapid assembly at multiple angles. When used for positioning review, it can avoid the problem of conventional positioning steel plates being unusable due to the deviation of anchor bolts.

[0016] 4. The device is equipped with reserved precision bolt positioning holes. After the installation and tightening accuracy is verified, the repetitive operation of bolt positioning review can be simplified to the use of verification tools, which shortens the review time of the entire set of bolts and improves the efficiency of positioning review.

[0025] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] Example 1 The present invention discloses a Figure 1-3 The quick-install anchor bolt positioning and inspection combined connection device shown in the figure uses an existing one-piece steel plate to split into a positioning plate and a connecting plate. The positioning plate is divided into a mutually hinged positioning mother plate and a positioning sub-plate 6. The positioning mother plate is further divided into a central positioning mother plate 3 and a corner positioning mother plate 1. Both positioning mother plates are installed and closed with the corresponding positioning sub-plates 6 to form high-precision anchor bolt positioning holes (hole diameter is the anchor bolt diameter + 2mm); The connecting plate is used to connect two adjacent positioning motherboards, and is divided into a horizontal long connecting plate 5 and a vertical short connecting plate 2. According to the designed bolt hole spacing, the long connecting plate 5 is used to connect the two adjacent corner positioning motherboards 1 horizontally, and the short connecting plate 2 is used to connect the adjacent corner positioning motherboards 1 and the middle positioning motherboard 3 vertically. The positioning motherboard and the connecting plate form an overall positioning frame. The length of the connecting plate is determined by the reserved connection hole spacing of the positioning motherboard.

[0027] Example 2 The present application also provides a fastening device, which uses any of bolts and matching butterfly nuts, pin shafts and matching cotter pins, wires or cable ties to complete the detachable fastening of the positioning motherboard and the connecting plate, and the positioning motherboard and the positioning sub-plate 6.

[0028] Example 3 When this application is used in the bolt group positioning and installation process, the device connecting plate can be replaced with two sets of 2020 European standard aluminum profiles, the length of which corresponds to the long and short sides of the column foot, and the aluminum profiles are formed into a rectangular frame using angle codes and L-shaped connecting plates. T-bolts and butterfly nuts are used to complete the connection between the positioning plate and the aluminum profile, thereby enhancing the overall rigidity of the quick-install device. Two sets of quick-install devices are used, and the connection between the embedded foundation steel bars and the lower-level device is adopted to replace the conventional positioning reinforcement construction process of welding bolts and steel bars, thereby reducing the impact of welding on the heat treatment of steel bars and bolts.

[0029] Example 4 When this device is used in the positioning and verification process of the anchor bolts after concrete pouring, the total number of column foot bolt group plane dimensions to be verified can be reduced to at least 1, saving the total number of column foot bolts to be verified and speeding up the dimension verification period. The modular design and processing of assembly parts, combined with auxiliary positioning tools, can achieve positioning and dimension verification of column foot bolts with different cross-sections by replacing different connecting plates, thus expanding the application scenarios of the tool. The material consumption of the quick-install device is greatly reduced compared to the conventional form. By processing the materials according to the existing design and using steel plates with the same column foot cross-section size, 4 sets of quick-install devices can be produced. The blanking structure diagram is shown as follows. Figure 4 As shown. After the connecting plate material is changed from 4mm thick Q235B steel plate to 2020 / 3030 aluminum profile, the rigidity of the quick-install device is improved. The upper and lower sets of quick-install devices are used for the positioning and reinforcement process of the anchor bolts. After the steel bars embedded in the foundation are effectively connected to the device, the installation method of welding the anchor bolts and the foundation steel bars can be replaced, reducing the impact of welding on the heat treatment of the steel bars and bolts. Figure 6 shown.

[0030] Example 5 When the diameter of the anchor bolt is smaller than the positioning hole formed by the positioning mother plate and the positioning sub-plate, insert the anchor bolt into the positioning hole. Figure 5 The auxiliary positioning tube 7 shown is used to fasten the anchor bolts by means of the fastening screws 8 provided in pairs on the side of the auxiliary positioning tube 7, thereby achieving a firm connection between the anchor bolts and the positioning plate.

Without departing from the spirit and essence of the present invention, persons of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions shall be within the scope of the present invention. Any changes or substitutions that can be easily conceived by persons skilled in the art within the technical scope disclosed in the present invention shall be within the scope of protection of the present invention.
