Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a combined anchor bolt auxiliary installation and positioning device. Background Technology

[0002] There are two technical challenges in connecting portal steel frame columns to the foundation. The first is quickly and accurately locating the positioning points and then pre-embedding the anchor bolts. The second is that the anchor bolts are prone to displacement or tilting during concrete pouring, causing them to deviate from their intended positions and easily resulting in rework losses. Current technology often involves manually locating and positioning each anchor bolt individually, which is not only inefficient but also prone to significant errors. Furthermore, there is currently no effective method to prevent the tilting and displacement of anchor bolts during concrete pouring. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a combined anchor bolt auxiliary installation and positioning device, which specifically includes the following:

[0004] A combined anchor bolt auxiliary installation and positioning device includes a base plate, at least two auxiliary installation tubes, and at least one horizontal support device.

[0005] The base plate has the same external dimensions as the column base plate in the construction drawing. The base plate has at least two auxiliary mounting holes that penetrate the upper and lower surfaces of the base plate. The lower surface of the base plate has an isolation layer. The position of the auxiliary mounting holes can be set according to the combination method and position of the combined anchor bolts (i.e., the diameter, spacing and number of bolt holes on the column base plate in the design drawing). The function of the isolation layer is to isolate the lower surface of the base plate from the concrete pouring layer, so as to facilitate the subsequent peeling of the base plate from the surface of the pouring layer.

[0006] At least two auxiliary mounting tubes are disposed on the upper surface of the substrate, and are respectively located above the at least two auxiliary mounting holes and respectively communicating with the corresponding auxiliary mounting holes. The diameter of the auxiliary mounting tube is not less than the diameter of the auxiliary mounting hole. When pre-embedding and positioning the anchor bolts, first, the top of the pre-embedded anchor bolt is passed through the auxiliary mounting hole, and then through the auxiliary mounting tube located above the auxiliary mounting hole with an exposed end of not less than 130mm. According to the column base plate outline dimensions in the construction drawing, the substrate with the pre-embedded anchor bolts is laid flat at the base top elevation mark to achieve natural placement and positioning of the pre-embedded anchor bolts. After fixing, the foundation concrete is poured. Once the foundation concrete has set, the auxiliary installation pipes on the base plate are tapped to loosen the base plate of the integrated device from the top surface of the concrete foundation. Using the handles on the base plate (or using two or more auxiliary installation pipes), the device is pulled upwards. The base plate will then be pulled out from the top of the pre-set and set anchor bolts, causing the auxiliary installation positioning device to detach from the top surface of the concrete foundation. The heads of the pre-set and set anchor bolts will then protrude and remain on the top surface of the foundation. Subsequently, the bolt holes of the steel frame column base plate can be threaded through and fixed onto the pre-set anchor bolts to achieve the connection and fixation between the steel frame column and the foundation. The function of the auxiliary installation pipes is to naturally combine and position the pre-set anchor bolts to fix their vertical position and spacing, preventing displacement or shifting during concrete pouring, which would otherwise require rework and hole enlargement to connect them to the column base plate.

[0007] The at least one horizontal support device is disposed between the at least two auxiliary installation pipes and is respectively connected to the side wall of the at least two auxiliary installation pipes. The function of the horizontal support device is to support and fix the auxiliary installation pipes, increase their strength, and indirectly prevent the pre-embedded anchor bolts of the foundation from shifting during the concrete pouring process.

[0008] Furthermore, the center of the auxiliary mounting hole coincides with the vertical direction; the auxiliary mounting tube is vertically disposed on the upper surface of the substrate.

[0009] Furthermore, the auxiliary mounting tube is positioned above the auxiliary mounting hole, and the center of the auxiliary mounting tube coincides with the center of the auxiliary mounting hole.

[0010] Furthermore, it includes four auxiliary mounting holes and four auxiliary mounting tubes, with the four auxiliary mounting holes located at one corner of the rectangle respectively.

[0011] Furthermore, it includes two horizontal support devices, which are respectively arranged along the two diagonals of the rectangle, and their two ends are respectively connected to the sides of two auxiliary installation tubes located at the two diagonal endpoints of the rectangle. The diagonal arrangement further increases the horizontal and vertical strength and rigidity of the auxiliary installation tubes, making them more stable.

[0012] Furthermore, the isolation layer is a lubricating oil layer, a wax layer, a graphite layer, or a concrete release agent.

[0013] Furthermore, the height of the auxiliary installation tube shall not be less than 2 / 5 of the anchor bolt to be installed and not less than 200mm.

[0014] Furthermore, the substrate is rectangular, circular, or elliptical.

[0015] Furthermore, a handle is provided at each of the left and right ends and / or the front and rear ends of the upper surface of the substrate.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a combined anchor bolt auxiliary installation and positioning device, including a base plate, at least two auxiliary installation pipes, and at least one horizontal support device. When positioning the combined anchor bolts, the top of the pre-embedded anchor bolt is first passed through the auxiliary installation hole, and then through the auxiliary installation pipe located above the auxiliary installation hole, with the protrusion not less than 130mm. According to the column base plate's outer dimensions in the construction drawings, the base plate with the anchor bolts already inserted is placed flat at the marked elevation line on the base top to achieve natural placement, positioning, and fixing of the anchor bolts. Then, concrete pouring is carried out, and the foundation concrete... After final setting, tap the auxiliary mounting tubes on the base plate to loosen the base plate of the integrated device from the top surface of the concrete foundation. Use the handle on the base plate (or use two or more auxiliary mounting tubes) to pull the device upwards. The base plate will then be pulled out from the top of the pre-embedded anchor bolts that have been positioned and set, causing the auxiliary mounting positioning device to detach from the top surface of the concrete foundation. The heads of the pre-embedded anchor bolts that have been positioned and set in the foundation will then protrude and remain on the top surface of the foundation. Subsequently, the bolt holes of the steel frame column base plate can be inserted and fixed to the pre-embedded anchor bolts to achieve the connection and fixation between the steel frame column and the foundation.

[0018] In this device, auxiliary mounting holes are provided on the base plate. The position of the auxiliary mounting holes can be set according to the combination and positional requirements of the hole diameter, hole spacing, and number of bolt holes on the column base plate in the design drawings to achieve the pre-positioning of the pre-embedded anchor bolts. An isolation layer is provided on the lower surface of the base plate to isolate the lower surface of the base plate from the concrete pouring layer, facilitating the subsequent peeling of the base plate from the surface of the pouring layer. Auxiliary mounting tubes are provided on the upper surface of the base plate and are located above at least two auxiliary mounting holes, respectively, and are connected to the corresponding auxiliary mounting holes. The auxiliary mounting tubes can naturally combine to position and fix the vertical position of the pre-embedded anchor bolts, preventing the pre-embedded anchor bolts from shifting during the foundation concrete pouring process. In addition, this device is also provided with a horizontal support device to support the auxiliary mounting tubes. The diagonal arrangement increases its strength and rigidity while indirectly preventing the pre-embedded anchor bolts from shifting during the foundation concrete pouring process.

[0022] Reference Appendix Figure 1A combined anchor bolt auxiliary installation and positioning device includes a base plate 1, at least two auxiliary installation pipes 2, and at least one horizontal support device 3. The base plate 1 has at least two auxiliary installation holes penetrating its upper and lower surfaces. An isolation layer is provided on the lower surface of the base plate 1. The positions of the auxiliary installation holes can be set according to the combination and positional requirements of the hole diameter, hole spacing, and number of bolt holes on the column base plate in the design drawings. The isolation layer separates the lower surface of the base plate 1 from the concrete pouring layer, facilitating subsequent peeling of the base plate 1 from the concrete pouring layer surface. The at least two auxiliary installation pipes 2 are located on the upper surface of the base plate 1, respectively above the at least two auxiliary installation holes and respectively penetrating the corresponding auxiliary installation holes. The diameter of the auxiliary installation pipe 2 is not less than the diameter of the auxiliary installation hole. When positioning the pre-embedded anchor bolts, the top of the pre-embedded anchor bolt 6 is first inserted through the auxiliary installation pipe 3. The holes are drilled, and then the auxiliary installation pipe 2, located above the auxiliary installation holes, is passed through with an overhang of at least 130mm. According to the column base plate dimensions in the construction drawings, the base plate 1, which already has the anchor bolts inserted, is laid flat at the marked position on the top of the foundation to achieve the natural placement, positioning, and fixation of the pre-embedded anchor bolts 6. Then, concrete is poured. After the foundation concrete has set, the auxiliary installation pipes 2 on the base plate are tapped to loosen the base plate 1 of the integrated device from the top surface of the concrete foundation. The device is then pulled upward using the handle 5 on the base plate 1 (or using two or more auxiliary installation pipes 2). The base plate 1, which is integrated with the foundation, will be pulled out from the top of the pre-embedded anchor bolts 6 that have been positioned and set, so that the auxiliary installation positioning device is removed from the top surface of the concrete foundation. The heads of the pre-embedded anchor bolts 6 that have been positioned and set in the foundation will protrude and remain on the top surface of the foundation. Subsequently, the bolt holes of the column base plate can be inserted and fixed onto the pre-embedded anchor bolts 6 to achieve the connection and fixation between the steel frame column and the foundation. The auxiliary installation pipe 2 serves to naturally position and fix the vertical position of the pre-embedded anchor bolts 6, preventing displacement during foundation concrete pouring and subsequent failure to connect with the column base plate, requiring rework and hole enlargement. At least one horizontal support device 3 is positioned between the at least two auxiliary installation pipes 2 and connected to the side walls of each of the at least two auxiliary installation pipes 2. The horizontal support device 3 supports and fixes the auxiliary installation pipes 2; its diagonal arrangement increases its strength and rigidity while indirectly preventing displacement of the pre-embedded anchor bolts 6 during concrete pouring. It should be noted that the anchor bolt 6 includes a vertical section and an anchoring section 7.

[0023] In some embodiments of this utility model, the center of the auxiliary mounting hole coincides with the vertical direction; the auxiliary mounting tube 2 is vertically disposed on the upper surface of the substrate 1.

[0024] In some embodiments of this utility model, the auxiliary mounting tube 2 is disposed above the auxiliary mounting hole, and the center of the auxiliary mounting tube 2 coincides with the center of the auxiliary mounting hole.

[0025] In some embodiments of this utility model, four auxiliary mounting holes and four auxiliary mounting tubes 2 are included, and the four auxiliary mounting holes are respectively located on one corner side of the rectangle.

[0026] In some embodiments of this utility model, two horizontal support devices 3 are included. The two horizontal support devices 3 are respectively arranged along the two diagonals of the rectangle, and their two ends are respectively connected to the sides of two auxiliary installation pipes 2 located at the two diagonal endpoints of the rectangle. The diagonal arrangement further increases the horizontal and vertical strength and rigidity of the auxiliary installation pipes, making them more stable.

[0027] In some embodiments of this utility model, the isolation layer is a lubricating oil layer, a wax layer, a graphite layer, or a concrete release agent.

[0028] In some embodiments of this utility model, the height of the auxiliary installation tube 2 is not less than 2 / 5 of the anchor bolt to be installed and not less than 200mm.

[0029] In some embodiments of this utility model, the substrate 1 is rectangular, circular, or elliptical.

[0030] In some embodiments of this utility model, a handle 5 is provided at each of the left and right ends and / or the front and rear ends of the upper surface of the substrate 1.

[0031] The combined anchor bolt auxiliary installation and positioning device disclosed in this utility model includes the following steps when positioning combined pre-embedded anchor bolts:

[0032] (1) First, select the processing base plate 1 according to the outer dimensions of the column base plate in the construction drawing, and set and process the auxiliary mounting holes on the base plate 1 according to the combination method and position requirements of the hole diameter, hole spacing and quantity of bolt holes on the column base plate in the design drawing. Then, add the auxiliary mounting pipe 2 above the auxiliary mounting hole and add the diagonal support 3 between the auxiliary mounting pipes 2 to complete the processing of the combined anchor bolt auxiliary installation positioning device, and apply the isolation layer to the bottom of the base plate.

[0033] (2) Pass the top of each pre-embedded anchor bolt 6 through each auxiliary installation hole, and then pass through the auxiliary installation pipe 2 located above the auxiliary installation hole with an exposed end of not less than 130mm. According to the column base plate outline dimensions in the construction drawing, place the base plate with the anchor bolts already inserted at the base top elevation mark position to achieve the natural placement, positioning and fixing of the combined pre-embedded anchor bolts 6.

[0034] (3) Then, the top of the pre-embedded anchor bolts 6 that have passed through the top opening of the auxiliary installation pipe 2 is wrapped with plastic film or PVC sleeve for protection;

[0035] (4) Then, insert and fix the 6 sets of pre-embedded anchor bolts located below the base plate 1 into the steel reinforcement of each steel frame column independent foundation, and make the bottom surface of the base plate 1 flush with the top surface of the independent foundation.

[0036] (5) Finally, pour the foundation concrete. After the concrete has solidified, tap each auxiliary installation pipe 2 on the base plate to loosen the base plate 1 of the integrated device from the top surface of the concrete foundation. Use the handle 5 on the base plate 1 (or use two or more auxiliary installation pipes) to pull the device upwards and peel the base plate 1 of the auxiliary positioning device from the concrete surface. The base plate 1 will be pulled out from the top of the pre-embedded anchor bolt 6 that has been positioned and solidified.

[0037] In this device, the base plate 1 is provided with auxiliary mounting holes. The position of the auxiliary mounting holes can be set according to the combination and positional requirements of the hole diameter, hole spacing, and number of bolt holes on the column base plate in the design drawings, so as to achieve the pre-positioning of the pre-embedded anchor bolts 6. An isolation layer is provided on the lower surface of the base plate 1, which can isolate the lower surface of the base plate 1 from the concrete pouring layer, making it convenient to peel the base plate 1 from the surface of the foundation concrete pouring layer later. The auxiliary mounting pipes 2 are provided on the upper surface of the base plate 1 and are respectively located above the at least two auxiliary mounting holes and respectively communicating with the corresponding auxiliary mounting holes. The auxiliary mounting pipes 2 can naturally combine to position and fix the vertical position of the pre-embedded anchor bolts 6, preventing the pre-embedded anchor bolts 6 from shifting during the foundation concrete pouring process. In addition, this device is also provided with a horizontal support device 3, which can support and fix the auxiliary mounting pipes 2. The diagonal arrangement increases its strength and rigidity, while indirectly preventing the pre-embedded anchor bolts 6 from shifting during the foundation concrete pouring process.
