Description

Technical Field

[0001] The utility model relates to a pre-embedded positioning technology, belongs to the field of steel structures, and specifically relates to a pre-embedded positioning device for a steel structure. Background Art

[0002] Steel structure is one type of building structure, which can be composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates.

[0003] The pre-embedded steel structure is an important construction step that determines the foundation of the steel structure. It mainly involves placing embedded plates, anchor rods, concrete, etc. in the foundation pit. There are currently two main construction methods. One is to place the embedded plates in the foundation pit and then pour concrete. In order to ensure the quality and durability of the concrete structure, it is necessary to exhaust the gas in the concrete through vibration equipment, and finally wait for the concrete to solidify. The second is to pour concrete into the foundation pit first and vibrate to exhaust the gas, and then place the embedded plates in the concrete and wait until the concrete solidifies. These two construction methods have the following problems: the embedded plates are easily sunk into the concrete due to mechanical vibration or lack of support when placed, which makes it impossible to accurately position the embedded plates, resulting in uneven end faces and tilted ends, thus affecting the subsequent installation of the steel structure. Summary of the invention

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, the steel structure embedded positioning device comprises:

[0051] A plurality of positioning plates 30 are arranged on the peripheral side of the embedded plate 10; the cross section of the positioning plate 30 is an inverted L-shaped structure, and the inner two surfaces of the L-shaped structure are in contact with the peripheral side and the upper end surface of the embedded plate 10 respectively;

[0052] The support rod assembly 50 is connected between two sides of adjacent positioning plates 30 and is configured to fix the plurality of positioning plates 30 to the peripheral side of the embedded plate 10;

[0053] A support arm 21 is rotatably mounted on each positioning plate 30;

[0054] A support pad 22 is connected to the fixed foundation and is lifted and lowered on the support arm 21;

[0055] Specifically, the positioning plate 30 is configured to be connected to the embedded plate 10. The cross section of the positioning plate 30 is an L-shaped structure, which enables it to contact the circumference and the upper end of the embedded plate 10, that is, the circumference contact is used for clamping, and the upper end contact is used for limiting;

[0056] A support arm 21, one end of which is connected to the fixed foundation through a support pad 22, and the other end of which is connected to the positioning plate 30;

[0057] When the embedded positioning device for steel structure is used, multiple positioning plates 30 are arranged on the peripheral side of the embedded plate 10, and the adjacent positioning plates 30 are connected and fixed by the support rod assembly 50. Under the action of the support rod assembly 50, the positioning plates 30 are fixed on the embedded plate 10; the positioning plates 30 are described as having two sides, and the adjacent positioning plates 30 are connected by the support rod assembly 50 at the sides close to each other, that is, the multiple positioning plates 30 and the multiple support rod assemblies 50 form a closed loop;

[0058] The embedded plate 10 is placed in a foundation pit with concrete or in a foundation pit without concrete (concrete is injected after adjustment is completed), and then the support arms 21 on the positioning plate 30 are unfolded so that the multiple support arms 21 extend outward to a suitable position;

[0059] The support pad 22 is adjusted so that it contacts the fixed foundation to play a supporting role, that is, the fixed foundation is a reference surface, which can be the outer surface of the foundation pit, the inner wall of the foundation pit, etc., which is not affected by concrete filling, mechanical vibration, etc.;

[0060] Place the spirit level on the embedded plate 10. When the embedded plate 10 is uneven or the height deviation at a certain position is too large, rotate the support pad 22 in the corresponding direction, and drive the positioning plate 30 and the embedded plate 10 connected to the positioning plate 30 through the support arm 21 to adjust the height so that the embedded plate 10 meets the requirements, thereby completing the adjustment and positioning of the embedded plate 10.

[0061] In some examples of the present invention, Figure 2 , Figure 3As shown, there are four positioning plates 30, which are located at the four corners of the embedded plate 10;

[0066] The support arms 21 and the support pads 22 are correspondingly arranged on each positioning plate 30 , that is, the positioning plate 30 and the embedded plate 10 are adjusted by adjusting the height of the four corners relative to the fixed foundation.

[0067] In some examples of the present invention, Figure 4 As shown, the number of the positioning plates 30 is two, and they are connected to the diagonal positions of the embedded plate 10;

[0068] The profile of the positioning plate 30 is an L-shaped structure, and the length of each side is not less than half of the length of the side of the embedded plate 10;

[0069] Support arms 21 are provided on both sides of the positioning plate 30;

[0070] Specifically, this example is applicable to the embedded plate 10 of a smaller size or a square structure;

[0071] The two positioning plates 30 are respectively located at diagonal positions of the embedded plate 10, and the two sides of the adjacent positioning plates 30 are connected by the support rod assembly 50, that is, one side of the positioning plate 30A is connected to the side adjacent to the positioning plate 30B by the support rod assembly 50, and the other side of the positioning plate 30A is connected to the other side adjacent to the positioning plate 30B by the support rod assembly 50;

[0072] In this state, the lengths of the support rod assemblies 50 are substantially the same, and a pair of support rod assemblies 50 connect the two positioning plates 30 and the embedded plate 10;

[0073] The length of each side of the positioning plate 30 is not less than half of the length of the side of the embedded plate 10, which can ensure the extrusion contact surface between the positioning plate 30 and the embedded plate 10, and make the pair of support arms 21 on each positioning plate 30 evenly distributed.

[0074] A pair of support arms 21 are provided on the positioning plate 30. At this time, the support arms 21 can be located in the middle of each side of the embedded plate 10, and the positioning plate 30 and the embedded plate 10 can be adjusted by adjusting the height of the middle position relative to the fixed foundation.

[0075] In some examples of the present invention, Figure 5 , Figure 6 As shown, the positioning plate 30 includes:

[0076] The first fixed plate 31 and the second fixed plate 32 are rotatably connected via a third support shaft 43;

[0077] The support arm 21 is connected to the third support shaft 43;

[0078] Specifically, this example is applicable to the embedded plate 10 of polygonal or circular structure;

[0079] According to the shape of the embedded plate 10, a suitable number of positioning plates 30 are selected, and the lengths of the first fixed plate 31 and the second fixed plate 32 can be the same;

[0080] The positioning plate 30 is composed of a first fixed plate 31 and a second fixed plate 32, that is, the first fixed plate 31 and the second fixed plate 32 are rotatably connected by a third support shaft 43, and can match embedded plates 10 of different structures;

[0081] Take the embedded plate 10 as a circular structure and three positioning plates 30 as an example for explanation, at this time, the first fixed plate 31A and the adjacent first fixed plate 31B are connected by the support rod assembly 50, the second fixed plate 32A and the adjacent second fixed plate 32C are connected by the support rod assembly 50, and the second fixed plate 32B and the adjacent first fixed plate 31C are connected by the support rod assembly 50;

[0082] As explained, the support rod assembly 50 should avoid the anchor position on the embedded plate 10;

[0083] In this state, the support arm 21 is installed on the third support shaft 43, that is, the support arm 21 is located in the middle of the positioning plate 30, and the positioning plate 30 and the embedded plate 10 are adjusted by the height of multiple support arms 21 relative to the fixed foundation.

[0084] In some examples of the present invention, Figure 3 As shown, the support rod assembly 50 includes:

[0085] One end of the first support rod 51 and the second support rod 52 are respectively detachably connected to the adjacent positioning plates 30;

[0086] The adjusting cylinder 53 is connected to the other ends of the first support rod 51 and the second support rod 52 in opposite directions with threads;

[0087] When the adjusting cylinder 53 rotates, the first support rod 51 and the second support rod 52 move closer to or farther from each other;

[0088] Furthermore, a first support shaft 41 and a second support shaft 42 are respectively fixed on both sides of the positioning plate 30;

[0089] Both ends of the first support rod 51 and the second support rod 52 are provided with through holes 212 which are sleeved on the first support shaft 41 and the second support shaft 42;

[0090] Specifically, the first support rod 51 and the second support rod 52 are provided with through holes 212, and the first support rod 51 and the second support rod 52 can be directly mounted on the first support shaft 41 and the second support shaft 42 respectively, so as to realize the quick disassembly and assembly of the first support rod 51 and the second support rod 52;

[0091] As explained, the first support shaft 41 and the second support shaft 42 have the same size;

[0092] The two ends of the adjusting cylinder 53 are respectively connected to the first support rod 51 and the second support rod 52 with reverse threads. When the adjusting cylinder 53 rotates, the first support rod 51 and the second support rod 52 move closer to or farther away from each other, so that one side of the adjacent positioning plates 30 can be tightened and fixed to each other, or loosened and disassembled.

[0093] In some examples of the present utility model, the support arm 21 is a telescopic rod structure that is telescopic and positionable;

[0094] The support pad 22 is threadedly mounted on the support arm 21;

[0095] Specifically, the support arm 21 is a telescopic rod that can be adjusted in length to a fixed base at different positions;

[0096] The support pad 22 is provided with a fixed shaft, which is threadedly connected to the support arm 21 for lifting and lowering adjustment;

[0097] Preferably, the support pad 22 can be connected to the support arm 21 through a support seat, and the support seat can be adjusted and locked at various angles to match different angles.

[0098] In some examples of the present invention, Figure 7 As shown, the support arm 21 is provided with a support cylinder 23 which can move along its length direction and can be positioned;

[0099] The fixed shaft on the support pad 22 is threadedly mounted on the support cylinder 23;

[0100] Specifically, the support cylinder 23 moves on the support arm 21 to adjust different positions and facilitate the support pad 22 to contact and support the fixed foundation;

[0101] The fixed shaft on the support pad 22 is threadedly mounted on the support cylinder 23 to facilitate height adjustment.

[0102] In an embodiment of the movement of the support cylinder 23, a slide groove is provided on the support arm 21, the support cylinder 23 is slidably located on the slide groove, and a threaded bolt is provided on the support cylinder 23, and after the bolt is rotated, it presses on the support arm 21 to position the support cylinder 23;

[0103] As another embodiment of supporting the cylinder 23 to move, Figure 7 , Figure 8 As shown, the support arm 21 is provided with a strip groove 211 arranged along its length direction, and a plurality of through holes 212 arranged at intervals and concentric with the strip groove 211;

[0104] A pair of parallel cutouts are provided on the support cylinder 23;

[0105] When the pair of cutouts are parallel to the width of the strip groove 211, the support cylinder 23 is slidably located in the strip groove 211;

[0106] The outer diameter of the support cylinder 23 matches the through hole 212, the lower end contacts the support arm 21, and the upper end passes through the support arm 21 and is threaded with a positioning nut 24;

[0107] Specifically, a pair of cutouts are provided on the support cylinder 23, and the distance between the pair of cutouts is smaller than the width of the strip groove 211. The outer diameter of the support cylinder 23 matches the through hole 212 and is larger than the width of the strip groove 211.

[0108] Therefore, when a pair of cutouts are parallel to the width of the strip groove 211, the support cylinder 23 slides in the strip groove 211. When the support cylinder 23 moves to a suitable through hole 212, the support cylinder 23 is rotated so that the cutouts and the strip groove 211 are staggered with each other. At this time, the support cylinder 23 is positioned in the corresponding through hole 212, so that the support cylinder 23 is positioned on the support arm 21. In addition, the lower end of the support cylinder 23 contacts the support arm 21, and the upper end passes through the support arm 21 and is threaded with a positioning nut 24, so that the support cylinder 23 is positioned at a height on the support arm 21.

[0109] In this example, the support cylinder 23 is rotated to achieve movement of the support cylinder 23 in the strip groove 211 and locking and positioning in the through hole 212. The operation is simple and convenient. Compared with the locking and positioning by rotating the bolt in the above-mentioned embodiment, this example does not require additional action on the bolt.

[0110] In some examples of the present utility model, the contact surface between the positioning plate 30 and the embedded plate 10 is provided with elastic concave and convex points;

[0111] Specifically, the concave and convex points are used to increase the friction between the positioning plate 30 and the embedded plate 10 to prevent the positioning plate 30 from falling off from the embedded plate 10 .
