Description

Technical Field

[0001] This utility model belongs to the field of auxiliary fixing technology for concrete embedded parts of sign foundations, and particularly relates to an installation device for concrete embedded parts of sign foundations. Background Technology

[0002] The typical dimensions of the concrete foundation pit for signage are: width / length: 1.2m × 1.5m to 1.8m × 2.4m, depth: 1.0m to 1.5m. After the foundation pit is excavated, spacers are installed; embedded parts are then installed on the spacers; concrete is poured, vibrated, and cured. This process has drawbacks: during concrete pouring, embedded parts are prone to displacement or even overturning, affecting installation accuracy; during vibration, embedded parts are prone to slipping off the spacers, causing accuracy deviations and affecting subsequent flange installations. This is because the embedded parts are directly installed on the spacers and only subjected to upward support. Horizontal forces generated during concrete pouring or vibration can cause displacement of the embedded parts. Excessive displacement can lead to overturning, affecting installation accuracy and subsequent construction processes.

[0003] Currently, the solution to the above situation involves manually adjusting the position of the embedded parts, which is time-consuming. To ensure concrete quality, repeated vibration is required, increasing machinery and labor costs and affecting the construction schedule. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a sign foundation concrete embedded part installation device, which aims to solve the technical problem that after the foundation pit is excavated, when installing pad blocks, installing embedded parts on the pad blocks, and carrying out concrete pouring and vibration, the embedded parts are easily displaced or even overturned, affecting the installation accuracy.

[0005] The present invention is implemented as follows:

[0006] An installation device for embedded concrete components in a sign foundation is provided. The device includes a rectangular frame, a fixing groove on the top surface of the rectangular frame, a screw inserted in the fixing groove, a connecting seat threaded to the middle of the screw, and a vertical fixing rod intersecting the screw. The bottom of the vertical fixing rod is detachably fixed to the top of the embedded component.

[0007] Furthermore, the rectangular frame is cuboid in shape, including a bottom frame formed by welding four first horizontal bars, a top frame formed by welding four second horizontal bars, and the bottom frame and top frame are connected by vertical bars to form a frame-like cuboid frame; the first horizontal bars, second horizontal bars and vertical bars form a through hole.

[0008] Furthermore, the connecting seat is cuboid in shape, and the connecting seat has intersecting or mutually perpendicular horizontal holes and vertical holes; the horizontal holes of the connecting seat are threadedly connected to the screw; the vertical holes of the connecting seat and the vertical fixing rod are clearance-fitted, the surface of the vertical fixing rod is threaded, and a locking nut is threadedly connected to the surface of the vertical fixing rod.

[0009] Furthermore, the fixing groove is triangular, rectangular, or trapezoidal.

[0010] Furthermore, the screw is inserted into the fixing groove via a fixing block.

[0011] Furthermore, the shape of the fixing block is adapted to the shape of the fixing groove.

[0012] Furthermore, the fixing grooves are evenly arranged along the top surface of the rectangular frame.

[0013] Furthermore, a quick-release clamp is fixed to the top of the vertical fixing rod.

[0014] The advantages of this invention are as follows: First, the frame is placed symmetrically and horizontally above the foundation pit for the sign to be poured. Then, the lower part of the embedded part is placed on the pad, and the upper part of the embedded part is fixed by a vertical fixing rod.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figure 1 The diagram shown is a structural diagram of a sign foundation concrete embedded part installation device provided in an embodiment of this utility model, comprising:

[0025] A rectangular frame 1 has a fixing groove 12 on its top surface. A screw 10 is inserted into the fixing groove 12. A connecting seat 3 is threaded to the middle of the screw 10. The connecting seat 3 has a vertical fixing rod 2 that intersects with the screw 10. The bottom of the vertical fixing rod 2 is detachably fixed to the top of the embedded part.

[0026] In this embodiment of the invention, the frame 1 is first placed symmetrically and horizontally above the foundation pit of the sign to be poured. Then, the lower part of the embedded part is placed on the pad, and the upper part of the embedded part is fixed by a vertical fixing rod. The horizontal position of the embedded part is precisely adjusted using a connecting seat. This improves the positioning accuracy of the embedded part and enhances the stability during the pouring process, thereby ensuring stability during the pouring and vibration operations.

[0027] The term "horizontal placement" refers to placing the frame 1 on the top surface of the foundation pit 14 with the center line of symmetry of the foundation pit 14 as a reference, so that each side of the frame 1 is symmetrical to the center of the foundation pit 14, and the top surface of the frame 1 remains horizontal.

[0028] The rectangular frame 1 is cuboid in shape, including a bottom frame formed by welding four first horizontal bars 6 and a top frame formed by welding four second horizontal bars 8. The bottom frame and the top frame are connected by vertical bars 7 to form a frame-like cuboid frame 1; the first horizontal bars 6, the second horizontal bars 8 and the vertical bars 7 form a through hole 9.

[0029] The connecting seat 3 is rectangular and has intersecting or perpendicular horizontal holes 301 and vertical holes. The horizontal holes 301 are threaded to the screw 10. The vertical holes and the vertical fixing rod 2 are clearance-fitted. The surface of the vertical fixing rod 2 is threaded and a locking nut 5 is threaded to the surface of the vertical fixing rod 2. By adjusting the locking nut 5, the position of the locking nut 5 on the vertical fixing rod 2 is changed, thereby realizing the position of the bottom end of the vertical fixing rod 2 relative to the top surface of the connecting seat 3 to adapt to the top height of different embedded parts.

[0030] In practical use, since the connecting seat 3 and the vertical fixing rod 2 are clearance fit, the vertical fixing rod 2 can move freely in the connecting seat 3. When it is necessary to fix it to the top of the embedded part 16, first rotate the connecting seat 3 or move the screw 10. If necessary, the position of the frame 1 can be moved appropriately to ensure that the connecting seat 3 is in a suitable position on the top of the embedded part 16. Then, insert the vertical fixing rod 2 into the vertical hole of the connecting seat, rotate the locking nut, and adjust the distance between the vertical fixing rod 2 and the top of the embedded part 16 until the vertical fixing rod 2 and the top of the embedded part 16 can be fixed together.

[0031] Preferably, the fixing groove 12 is triangular, rectangular, or trapezoidal.

[0032] Preferably, the screw 10 is inserted into the fixing groove 12 via the fixing block 11.

[0033] Preferably, when the fixing groove 12 is triangular, the fixing block 11 is a triangle adapted to the fixing groove; when the fixing groove 12 is rectangular, the fixing block 11 is a rectangle adapted to the fixing groove; when the fixing groove 12 is trapezoidal, the fixing block 11 is a trapezoid adapted to the fixing groove.

[0034] Preferably, the fixing groove 12 is evenly arranged along the top surface of the second crossbar 8.

[0035] The top of the vertical fixing rod 2 is fixed with a quick-release clamp 4. The quick-release clamp includes two semi-circular clamps. The two semi-circular clamps are connected at one end by a hinge and at the other end by a fastening mechanism to achieve locking. The fastening mechanism includes: worm gear type: the clamp band is tightened by rotating the worm, and the fastening force is maintained by the self-locking property of the gear; lever locking type: it has a handle lever, which can be pressed down to quickly lock and released to disassemble; spring clip type: it automatically locks by spring tension.

[0036] In specific use, first place the frame 1 on the top surface of the foundation 13. The foundation has a foundation pit 14, and a pad 15 is placed at the bottom of the foundation pit 14. The bottom of the embedded part 16 is placed on the top surface of the pad 15, and the top of the embedded part 16 is fixed to the bottom of the vertical fixing rod 2. Since the connecting seat 3 and the vertical fixing rod 2 are clearance fit, the vertical fixing rod 2 can move freely within the connecting seat 3. When it is necessary to fix it to the top of the embedded part 16, first rotate the connecting seat 3 or move the screw 10. If necessary, the position of the frame 1 can be moved appropriately to ensure that the connecting seat 3 is located on top of the embedded part 16. Position the vertical fixing rod 2 in a suitable location, then insert it into the vertical hole of the connecting seat. Turn the locking nut to adjust the distance between the vertical fixing rod 2 and the top of the embedded part 16 until the vertical fixing rod 2 and the top of the embedded part 16 can be fixed together. At this time, insert the top of the embedded part 16 into the quick-release clamp 4 at the bottom of the vertical fixing rod 2. The two semi-circular clamps are connected by hinges at one end to wrap the top of the embedded part. The other end of the clamps is provided with a U-shaped notch. A small screw is hinged in one of the U-shaped notches. Turn the small screw into the other U-shaped notch and then tighten it with a nut to achieve the purpose of clamping.

[0037] Preferably, the number of fixing seats 3 and vertical fixing rods 2 are the same, and the number is the same as the number of the top of the embedded parts; for example, Figure 1 As shown, there are four fixing bases 3, which are used to fix four pre-embedded parts at the top.
