Description

Technical Field

[0001] The utility model relates to the technical field of the installation of steel structure anchor bolts, in particular to an assembled steel structure bottom foundation structure. Background Technique

[0002] The steel structure is a structure composed of steel materials and is one of the main building structure types. Welds, bolts or rivets are usually used to connect each component or part. Due to its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Embedded anchor bolts are a very important construction process to ensure the installation accuracy of steel structure columns. At present, the traditional method of embedding anchor bolts is to directly embed them. Before the concrete foundation is poured, the bottom and top of the anchor bolts are respectively reinforced with the concrete steel cage, and then the concrete foundation is poured. However, due to the lack of integrity in the fixation of the anchor bolts, it is greatly affected by the concrete pouring. During the pouring process, the pouring and vibration of the concrete will cause the embedded anchor bolts to move and tilt. After the concrete solidifies, the position deviation of the anchor bolts is relatively large. If the deviation is not discovered and corrected in time, it will affect the later installation. Moreover, during the manual correction process, it is very easy to damage the anchor bolts, resulting in the entire poured concrete foundation being unable to be constructed and used, which not only increases the construction period but also consumes a large amount of manpower and material resources. Therefore, we propose an anchor bolt positioning structure to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide an assembled steel structure bottom foundation structure to solve the above problems.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] An assembled steel structure bottom foundation structure includes four anchor bolts. A bottom plate is sleeved outside the top of each anchor bolt. A correcting piece for keeping the anchor bolts in a vertical state is sleeved on the tops of the four anchor bolts together. The correcting piece includes a first correcting block, a second correcting block, a third correcting block and a fourth correcting block which are connected to each other. Threaded sleeves which are in threaded connection with the anchor bolts are rotatably arranged at the bottoms of the first correcting block, the second correcting block, the third correcting block and the fourth correcting block.

[0006] As a further description of the above technical scheme:

[0007] Guide rods are fixedly connected to two mutually perpendicular sides of the first correcting block, one side of the second correcting block and one side of the fourth correcting block. Installation sleeves are arranged on the perpendicular sides of the second correcting block and the fourth correcting block corresponding to the connected guide rods and on two mutually perpendicular sides of the third correcting block. Moving grooves which are slidably matched with the corresponding guide rods are formed in the installation sleeves.

[0008] As a further description of the above technical solution:

[0009] A positioning member is movably provided inside the movable end of the guide rod, and a plurality of fixing grooves communicating with the moving groove are provided in the upper part of the mounting sleeve for clamping the positioning member.

[0010] As a further description of the above technical solution:

[0011] The positioning member includes a stepped shaft and a fixing block protruding from the circumferential side of the top of the stepped shaft, and a circular mounting head is fixedly connected to the top end of the stepped shaft.

[0012] As a further description of the above technical solution:

[0013] An anti-slip groove is recessed on the circumferential side of the mounting head.

[0014] As a further description of the above technical solution:

[0015] A through hole communicating with the moving groove is provided in the lower part of the mounting sleeve for the large diameter section of the stepped shaft to move.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, the cooperation between the correction member and the positioning member ensures that the axis of the anchor bolt is always perpendicular to the bottom plate surface, avoiding the situation that the embedded anchor bolt moves and tilts due to the pouring and vibration of concrete during the casting of the concrete foundation, and is applicable to the correction of anchor bolts with various installation spacings.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0028] Embodiment 1:

[0029] As Figure 1-8 shown, an assembled steel structure bottom foot foundation structure includes four anchor bolts 1. A base plate 2 is sleeved outside the top of the anchor bolts 1. A calibration part 3 for keeping the anchor bolts 1 in a vertical state is sleeved on the top of the four anchor bolts 1 together. The calibration part 3 includes a first calibration block 31, a second calibration block 32, a third calibration block 33 and a fourth calibration block 34 which are connected to each other. Threaded sleeves 5 threadedly connected to the anchor bolts 1 are rotatably provided at the bottoms of the first calibration block 31, the second calibration block 32, the third calibration block 33 and the fourth calibration block 34. The cooperation between the calibration part 3 and the positioning part 4 ensures that the axis of the anchor bolt 1 is always perpendicular to the surface of the base plate 2, avoiding the situation that the embedded anchor bolts 1 move and tilt due to the pouring and vibration of concrete during the concrete foundation pouring process, and is applicable to the calibration of anchor bolts 1 with various installation spacings.

[0030] Embodiment 2:

[0031] Basically the same as the technical solution of Embodiment 1, the difference is that as Figure 1-8As shown in the figure, guide rods 6 are fixedly connected to two mutually perpendicular sides of the first calibration block 31, one side of the second calibration block 32, and one side of the fourth calibration block 34. Mounting sleeves 7 are provided on the vertical sides corresponding to the sides where the guide rods 6 are connected on the second calibration block 32 and the fourth calibration block 34, and on two mutually perpendicular sides of the third calibration block 33. A moving groove 8 that is slidably engaged with the corresponding guide rod 6 is formed in the mounting sleeve 7. A positioning member 4 is movably provided inside the movable end of the guide rod 6. A plurality of fixing grooves 9 that communicate with the moving groove 8 are formed in the upper part of the mounting sleeve 7 for clamping the positioning member 4. The positioning member 4 includes a stepped shaft 41 and a fixing block 42 protruding from the circumferential side of the top of the stepped shaft 41. A circular mounting head 43 is fixedly connected to the top end of the stepped shaft 41. The position of the corresponding guide rod 6 inside the mounting sleeve 7 is fixed by the engagement of the fixing block 42 with the fixing groove 9, so as to facilitate the change of the position of the threaded sleeve 5 threadedly connected to the anchor bolt 1 to be applicable to the installation of anchor bolts 1 with different installation spacings. Anti-slip grooves are recessed on the circumferential side of the mounting head 43, which is convenient for the operator's finger pulp to be pinched in the anti-slip grooves to rotate and move the positioning member 4 up and down.

[0032] Embodiment 3:

[0033] Basically the same as the technical solution of Embodiment 1, the difference is that, as Figure 2-8 shown in the figure, a through hole for the large-diameter section of the stepped shaft 41 to move is formed in the lower part of the mounting sleeve 7 and communicates with the moving groove 8, which can not only move the positioning member 4 up and down to take out or engage the fixing block 42 from the fixing groove 9, but also will not completely pull the positioning member 4 out of the guide rod 6.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
