Abstract
Description
Technical Field
[0001] The utility model relates to an embedded bolt, in particular to a combined embedded bolt structure. Background Art
[0002] During the concrete pouring process, the installation of embedded bolts for equipment involving concrete walls, columns, beams and other structures is particularly important. The utilization rate of combined embedded bolts in equipment installation is relatively high, and most of them are arranged in an even number of squares. The installation quality of combined embedded bolts is directly related to the installation quality of the equipment. In addition, when the embedded bolts have problems such as displacement and vertical deviation, the handling process will greatly consume the project cost and affect the project cycle.
[0003] Therefore, the known pre-embedded bolt method has the above-mentioned inconveniences and problems. Utility Model Content
[0004] The purpose of the utility model is to provide a safe and reliable combined embedded bolt structure.
[0005] To achieve the above objectives, the technical solution of the present invention is:
[0006] A combined embedded bolt structure includes four embedded bolts, a bolt positioning fixture, and two horizontal support frames, and is characterized by:
[0007] The four embedded bolts are fixed in place after the steel bars and templates are installed and inspected, and the cross-sections of the four embedded bolts are arranged in a square shape;
[0008] The bolt positioning fixture is composed of four flat steel positioning rulers with the same structure. A long slot is arranged in the middle of each flat steel positioning ruler. The four flat steel positioning rulers are overlapped with each other in a square shape. The overlap points are connected by bolts with movable clamping. The bolt positioning fixture cooperates with the four embedded bolts, so that the top of each embedded bolt with a nut is inserted into the long slot end of the corresponding two flat steel positioning rulers, and the long slot ends of the other two flat steel bars are inserted into the positioning support bolts. The bottom ends of the positioning support bolts are fixedly welded to the fixed channel steel and steel pipe for stability.
[0009] The two horizontal support frames are two X-shaped frames with the same structure. The four ends of the X-shaped frame are respectively provided with a locking sleeve with an open elliptical ring and a matching bolt. A rotating joint is provided in the center of the X-shaped frame. The rotating joint is an elliptical steel plate with a hole in the middle. The steel pipe a is fixed at both ends. The steel plates with holes are overlapped and tightened with bolts. After the assembly is completed, the bolts are tightened and the tightening bolts cooperate with the embedded bolts so that the two horizontal support frames are spaced apart and fit in the middle of the embedded bolts.
[0010] The combined embedded bolt structure of the present invention can also be further implemented by adopting the following technical measures.
[0011] In the aforementioned combined embedded bolt structure, the rod in the X-shaped bracket is a steel pipe.
[0012] After adopting the above technical solution, the combined embedded bolt structure of the utility model has the following advantages:
[0013] 1. The embedded bolts have a simple structure and are easy to manufacture;
[0014] 2. Quickly fix embedded bolts and accurately position them;
[0015] 3. Save construction costs and speed up construction progress. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In the figure: 1 embedded bolts, 2 bolt positioning fixture (including positioning caliper, fixed channel steel a), 3 horizontal support frame (including steel pipe b, rotating joint c, locking sleeve d). DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the embodiments and the accompanying drawings.
[0020] Example 1
[0021] The combined embedded bolt structure of the utility model comprises four embedded bolts 1 , a bolt positioning fixture 2 , and two horizontal support frames 3 .
[0022] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the combined embedded bolt structure of an embodiment of the present utility model. As shown in the figure, the four embedded bolts 1 are fixed in position after being inspected and accepted by the steel bars and templates, and the cross-sections of the four embedded bolts are arranged in a square shape.
[0023] The bolt positioning fixture 2 is four flat steel positioning rulers with the same structure. A long slot is arranged throughout the middle of each flat steel positioning ruler. The four flat steel positioning rulers are overlapped with each other in a square shape, and the overlapping points are connected by bolts with movable clamping. The bolt positioning fixture cooperates with the four embedded bolts so that the top of each embedded bolt with a nut is inserted into the long slot end of the corresponding two flat steel positioning rulers, and the long slot ends of the other two flat steel bars are inserted into the positioning support bolts. The bottom end of the positioning support bolt is fixedly welded to the fixed channel steel a and steel pipe for stability.
[0024] Figure 2This is a schematic diagram of the horizontal support frame structure of an embodiment of the present invention. The two horizontal support frames are identical X-shaped frames, each with a locking sleeve d at each end. A swivel joint c is located in the center of the X-shaped frame. Fastening bolts are coupled with embedded bolts. The locking sleeve d and swivel joint c can accommodate multiple sets of embedded bolts with varying diameters and embedded spacing, allowing the two horizontal support frames to fit together in the center of the embedded bolts. The rods in the X-shaped frames are steel pipes b.
[0025] Example 2
[0026] Installation steps of the combined embedded bolt structure of the utility model:
[0027] 1) Loosen all fasteners;
[0028] 2) Assemble the embedded bolts 1, bolt positioning fixture 2, and bolt horizontal support 3 to be embedded;
[0029] 3) Adjust the flat steel positioning ruler of the bolt positioning fixture 2 until the horizontal and vertical distances between the four bolts meet the requirements, and tighten the embedded bolt fasteners on the bolt positioning fixture 2;
[0030] 4) The two horizontal bolt supports 3 are linked together during adjustment of the bolt positioning fixture 2, securing the anchor bolts into a frame and ensuring that the spacing between the anchor bolts is not disturbed during the adjustment process. Tighten the locking sleeves d on the horizontal bolt supports 3 in sequence, ensuring that the locking sleeve d of the lower horizontal bolt support 3 is positioned above the embedded mark. The linkage between the two horizontal bolt supports 3 and the bolt positioning fixture 2 ensures the verticality of the bolts.
[0031] 5) Adjust the fasteners on the cross buckle gasket of the bolt positioning fixture 2 so that the extended length of the support bolts of the bolt positioning fixture 2 is consistent. The cross buckle gasket ensures that the support bolts are not movable;
[0032] 6) Fix the bolt installation system: Fix the entire bolt installation system through the support bolt a of the bolt positioning fixture 2. If the pre-buried bolts are on the ground, they can be fixed on-site by punching holes through the channel steel below the support bolts. If the pre-buried bolts are under the beam or on the column, they can be fixed by horizontally inserting wood, steel bars, round pipes, etc. through the channel steel below the support bolts.
[0033] The utility model has substantial characteristics and significant technological progress. Compared with the traditional method, the combined embedded bolt structure of the utility model provides a combined embedded bolt installation process with a simple structure, which is generally applicable to the installation of various square-arranged embedded bolts. It is safe and reliable to use, and can quickly fix the embedded bolts with accurate positioning, saving construction costs and speeding up construction progress.
[0034] The above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Persons skilled in the art may make various modifications or variations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention and are defined by the claims.
