Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building construction, and in particular to a staggered steel bar connection device and a connection method for prefabricated prefabricated components. Background Art

[0002] In recent years, China has proposed smart cities, green buildings, and building industrialization as future development directions for the construction industry. Vigorously developing prefabricated buildings is essential for increasing the industrialization of traditional construction methods. The technical level of prefabricated buildings directly reflects a country's construction capabilities and scientific and technological strength, making the comprehensive development of prefabricated buildings a top priority for the construction industry. In the construction of prefabricated buildings, the performance of the rebar connections within prefabricated components is a key factor in rebar force transmission, decisive for both the effectiveness of rebar force transmission and the integrity of the structure. The choice of rebar connection method directly impacts the construction speed and structural quality of the building.

[0003] The steel bar connection methods used in existing prefabricated structures are mainly sleeve grouting connection and constrained grouting anchor connection. In actual use, both of the above connection methods have obvious disadvantages. Among them, the sleeve grouting connection method requires high precision. If the position of the steel bar deviates slightly, it will be difficult for the on-site steel bar to pass into the sleeve. The density of the slurry after grouting cannot be guaranteed, and there is a lack of follow-up inspection measures after grouting. Not only is the construction quality unstable, but the steel bar connection is difficult and the construction is complicated. The constrained grouting anchor connection method also has high precision requirements, complex manufacturing process, and difficulty in on-site construction. In actual construction, the two connection methods are prone to problems such as complicated operation and non-standard construction. At the same time, for the common problem of misplaced steel bar connection in prefabricated prefabricated components, the existing steel bar connection method cannot connect the misplaced steel bars simply and quickly, and it is difficult to ensure the quality of the connection structure. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a staggered steel bar connection device for prefabricated components and a connection method for staggered steel bars using the above-mentioned connection device, which solves the shortcomings of the existing prefabricated steel bar connection technology, such as high precision requirements, complex processes, great difficulty in on-site construction, and unstable construction quality, as well as the common staggered steel bar connection problems in the connection of prefabricated components.

[0005] In order to solve the above technical problems, the present invention is implemented through the following technical solutions:

[0006] A staggered steel bar connection device for assembled prefabricated components includes a U-shaped slide rail steel plate, an interlocking slider, a pull rope and a double-hole ring. The characteristic is that the U-shaped slide rail steel plate is provided with a specific slide rail for the interlocking slider to slide, and the interlocking slider slides under the force of the pull rope, interlocking and connecting the steel bars to be connected on the prefabricated components in a staggered steel bar connection manner.

[0007] The U-shaped slide rail steel plate includes an arc-shaped tooth steel plate section and two rectangular slide rail steel plate sections, and the arc surface end of the arc-shaped tooth steel plate section is tangent to the ends of the two rectangular slide rail steel plate sections.

[0008] The arc-shaped latching tooth steel plate section is a 180° arc-shaped steel plate, and a plurality of latching teeth are provided in the arc-shaped area.

[0009] There is a rectangular hollowing in the middle of the rectangular slide rail steel plate section, the hollowing height is adapted to the interlocking slider, and the horizontal section of the rectangular hollowing is set as a triangular convex surface; the hollowing parts of the two rectangular slide rail steel plate sections are set in parallel to form a specific slide rail for the interlocking slider to slide.

[0010] The occlusal slider has an arc-shaped occlusal surface, and a plurality of teeth are provided in the arc-shaped area; a specific track for the pull rope to pass through is provided inside the occlusal slider, and both ends of the slider are adapted to the U-shaped slide rail steel plate slide rail.

[0011] The pull rope cleverly realizes the directional engagement of the slider through the specific track and knot method of the interlocking slider; as for the sliding direction of the interlocking slider, the first interlocking slider slides toward the end of the arc-shaped tooth steel plate section, and the second interlocking slider and the third interlocking slider slide toward each other.

[0012] The double-hole ring includes an upper hole ring and a lower hole ring; the pull rope passes through the upper hole ring and the lower hole ring of the double-hole ring respectively, the lower hole ring of the first double-hole ring is a dead knot, the pull rope is fixed and cannot slide, the upper hole ring is a loose knot, the pull rope can slide, and the first double-hole ring is welded to the end of the rectangular slide rail steel plate section; the upper hole ring and the lower hole ring of the second double-hole ring are both loose knots, the pull rope can slide in a direction, and the second double-hole ring is welded to the end of the third bite-type slider.

[0013] The pull rope is a steel wire rope or a steel strand.

[0014] The dislocated steel bar connecting device can realize the common connection of multiple steel bars to be connected by increasing the number of the bite-type sliders in pairs.

[0015] A method for connecting staggered steel bars using the staggered steel bar connecting device comprises the following steps:

[0016] Step 1: Adjust the sliders: adjust the interlocking sliders according to the positions of the steel bars to be connected, so that the interlocking sliders are located on both sides of the steel bars to be connected, and the relative distance between the arc-shaped tooth steel plate segment and the first interlocking slider, and the relative distance between the second interlocking slider and the third interlocking slider are not less than the diameter of the steel bars to be connected;

[0017] Step 2: Inserting steel bars: inserting the first steel bar to be connected between the arc-shaped toothed steel plate segment and the first interlocking slider, and inserting the second steel bar to be connected between the second interlocking slider and the third interlocking slider;

[0018] Step 3, pull the pull rope: pull the pull rope to slide the interlocking slider to engage the two steel bars to be connected respectively. After ensuring that the pull rope is fully tightened and positioned, tighten the pull rope at the end of the U-shaped slide rail steel plate to complete the connection of the dislocated steel bars.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The existing sleeve grouting connection and constrained grout anchor connection methods are prone to complex operation and non-standard construction during actual construction. The present invention is easy to operate and has a reasonable structural design. It does not require additional operator training. Only one pull of the pull rope is required to simply and quickly complete the connection process of the dislocated steel bars, thereby improving construction efficiency.

[0021] 2. The present invention has a wide range of applications, high connection quality, and great flexibility. It effectively solves the common problem of misaligned steel bar connection in the connection of prefabricated components. The connection mechanism in which the pull rope drives the slider to bite the steel bar can realize the connection of misaligned steel bars in small spaces, multiple spacings, and multiple diameters. It can also connect multiple misaligned steel bars together. The connection process is simple and fast, and there is less wet work on site, achieving the goal of green construction.

[0034] The U-shaped rail steel plate 31 is composed of an arc-shaped toothed steel plate segment 311 and two rectangular rail steel plate segments 312.
