Abstract

This invention relates to a snap-fit ​​type joint plate, which has several pre-drilled holes for fixing reinforcing bars to pass through. The pre-drilled holes are of an elongated oval structure. The snap-fit ​​is fixedly connected to the main body of the joint plate. When the fixing reinforcing bar is engaged with the snap-fit, the axis of the fixing reinforcing bar is aligned with one end of the pre-drilled hole of the elongated oval structure. The fixing reinforcing bar is inserted into the pre-drilled hole at a position offset from the snap-fit. After insertion, the fixing reinforcing bar is pressed into the arc of the snap-fit ​​from the notched corner of the snap-fit ​​and fixed. The position of the main body of the joint plate is adjusted, and the fixing reinforcing bar is tied to the external structural reinforcing bars to form a whole, thereby realizing the installation and fixing of the snap-fit ​​joint plate and eliminating the welding process. By opening the pre-drilled holes of the elongated oval structure in the main body of the joint plate, the fixing reinforcing bar can be initially misaligned with the snap-fit ​​when inserted into the pre-drilled hole. After adjusting the position, the fixing reinforcing bar is pressed into the snap-fit ​​to achieve engagement.

Description

Technical Field

[0001] This invention relates to a snap-fit ​​type fixed joint panel, belonging to the field of building technology. Background Technology

[0002] Emerging with the technology of cast-in-place concrete exterior walls, which utilize aluminum formwork construction to achieve one-time casting of the exterior wall, avoiding quality problems such as cracks and leaks, and saving construction time and improving efficiency. However, because cast-in-place concrete exterior walls alter the stress distribution of the original main structure of the building, the lateral stiffness of the building increases significantly, which is detrimental to the structure's seismic energy dissipation performance. Therefore, using tie-joint panels to separate cast-in-place non-load-bearing walls and shear walls can effectively solve the adverse effects of cast-in-place structures on the main structure. Tie-joint panels are materials used to create structural joints in concrete structures, typically between non-load-bearing walls and load-bearing beams, columns, and walls, to reduce the impact of earthquakes and other factors on the wall and prevent cracking. This technology has been widely promoted in the industry in recent years, and PVC-U prefabricated tie-joint panels are now widely used due to their convenient installation and low cost.

[0003] However, existing joint panel installation processes often require welding. The high temperatures generated during welding can easily melt through the PVC material, causing significant deformation of the joint panel and creating substantial construction quality risks. Therefore, reducing the adverse effects of welding on joint panel installation is an urgent problem to be solved.

[0004] For example, CN212743388U describes an aluminum formwork joint structure. Without affecting the passage of the reinforcing bars through the joint plate, the perforations can position the reinforcing bars and prevent the joint structure from loosening or shifting. However, the perforations on the joint plate for the reinforcing bars to pass through are round holes, which are inconvenient for adjustment after the reinforcing bars pass through. Summary of the Invention

[0005] The purpose of this invention is to provide a snap-fit ​​type fixed seam panel to solve the problems mentioned in the background art.

[0006] The technical solution of the present invention is as follows:

[0007] A snap-on type fixed seam panel, comprising:

[0008] The main body of the joint plate has several reserved holes for fixing reinforcing bars to pass through, and the reserved holes are of an elongated oval structure.

[0009] The buckle is fixedly connected to the main body of the seam panel;

[0010] When the fixed reinforcing bar is engaged with the snap-fit, the fixed reinforcing bar is aligned with the axis of one end of the reserved hole in the oblong structure.

[0011] Preferably, one side of the main body of the seam panel has an integral protrusion, and the buckle is fixed on the protrusion, so that there is a gap between the buckle and the side wall of the main body of the seam panel.

[0012] Preferably, the reserved holes are distributed in at least two columns, and the length extension direction of the reserved holes is perpendicular to the arrangement direction of each column of reserved holes.

[0013] Preferably, the inner wall of the buckle is provided with friction texture.

[0014] Preferably, the buckle is an arc structure with an arc greater than 180°, and the side of the buckle has a notch facing the corresponding reserved hole.

[0015] Preferably, the middle part of the buckle with the arc structure is integrated with the protrusion.

[0016] Preferably, the end of the buckle is movably connected to a movable plate along its arcuate extension direction, and an elastic element that drives the movable plate to move outward is connected between the movable plate and the buckle.

[0017] Preferably, each end of the buckle is provided with a movable plate, and a pull rope is connected between the two movable plates.

[0018] Preferably, the outer wall of the pull rope is fitted with a limiting bead, and the inner side wall of the buckle is uniformly provided with grooves that match the limiting bead.

[0019] Preferably, the outer wall of the pull rope is also fitted with a hollow bead with a fragile structure, and the hollow bead contains glue.

[0020] The present invention has the following beneficial effects:

[0021] Insert the fixing steel bar into the pre-drilled hole at the location where it is offset from the buckle. After insertion, press the fixing steel bar into the buckle arc from the notched corner to fix it. Adjust the position of the main body of the pull joint plate and tie the fixing steel bar to the external structural steel bar as a whole. This realizes the installation and fixation of the buckle pull joint plate, eliminating the welding process. It effectively solves the problem of high temperature from welding melting the PVC material and large deformation of the pull joint plate, which can lead to significant construction quality problems. At the same time, it saves construction costs.

[0022] This avoids the phenomenon of concrete flowing into the interior of the joint plate after it has fully melted, which would cause the joint plate to fail, thus greatly improving the installation qualification rate of the joint plate; it also eliminates the welding process, reducing the workload and material consumption on the installation site, greatly reducing installation costs and effectively controlling construction costs;

[0023] By creating a pre-drilled oval hole in the main body of the joint plate, the reinforcing bar can be initially misaligned with the clip when inserted into the pre-drilled hole. After adjusting the position, the reinforcing bar can be pressed into the clip to achieve a snap-fit ​​connection. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] like Figure 1-5 As shown, the fixing steel bar 3 is a ribbed steel bar;

[0035] The system includes a joint plate body 1, a clip 2, and a fixing steel bar 3. The joint plate body 1 has two rows of three long oval-shaped pre-drilled holes 4. The pre-drilled holes 4 have semi-circular arcs on both sides and a rectangular shape in the middle. The clip 2 is an arc with an arc greater than 180°. The clip 2 has a notch 6 on its side. The clip 2 is connected to the protruding part 5 in the longer direction of the joint plate body 1 and is isolated from the side of the joint plate body 1 in the longer direction. The center point of the arc of the clip 2 is at the same height as the center point of one end of the long oval-shaped pre-drilled hole 4.

[0036] The main body 1 of the joint panel and the clip 2 are extruded together in one step to form the finished joint panel. After the structural steel reinforcement of the shear wall is installed, the clip-fixed joint panel is positioned in the preset position. The fixing steel bar 3 is inserted into the reserved hole 4 at the part offset from the clip 2 according to the preset required length. After insertion, the fixing steel bar 3 is pressed into the arc of the clip 2 from the arc notch 6 and fixed. The position of the main body 1 of the joint panel is adjusted until it is positioned in the preset position. The fixing steel bar 3 is tied to the structural steel reinforcement as a whole to realize the installation and fixation of the clip-fixed joint panel.

[0037] The buckle 2 has a notch 6, which gives it a certain degree of elasticity and a small deformation range; the elongated pre-drilled hole 4 makes it easier to fix the reinforcing bar 3 into the main body 1 of the joint plate and fix it together with the main body 1 of the joint plate; the existing round hole cannot play a good role in fixing when inserted; the gap between the buckle 2 and the main body 1 of the joint plate is left, which is conducive to the buckle 2 being opened by the fixed reinforcing bar 3 and locked into the slot 2.

[0038] Example 2: Contains all the contents of Example 1, except that:

[0039] like Figure 6 As shown, both ends of the buckle 2 are provided with sliding grooves. The corresponding movable plates 22 are connected in an arc-shaped sliding (clearance fit) manner in the sliding grooves. The inner sidewall of the sliding groove and the movable plates 22 are connected with elastic elements 21. The elastic elements 21 can be compression springs. Several pull ropes 8 are connected between the two sets of movable plates 22. The pull ropes 8 are located inside the buckle 2. The strength of the pull ropes 8 themselves is greater than the connection strength between the pull ropes 8 and the movable plates 22. Under normal conditions, the elastic elements 21 are compressed and the movable plates 22 are retracted into the sliding grooves, so as not to prevent the fixing steel bar 3 from being inserted into the buckle 2 from the notch 6.

[0040] Working principle: The fixed reinforcing bar 3 is inserted into the buckle 2, which stretches the pull rope 8 so that its two ends break from the movable plate 22. The elastic element 21 loses its restraint and its elastic force pushes the movable plate 22 to slide outward in an arc shape. Thus, the two sets of movable plates 22 cooperate to close the notch 6, preventing the fixed reinforcing bar 3 from detaching from the notch 6.

[0041] Example 3: Includes all the content of Example 2:

[0042] like Figure 6-7 As shown, the inner wall of the buckle 2 is evenly provided with grooves 23, and the outer wall of the pull rope 8 is fitted with limiting beads 81 and hollow beads 82. The limiting beads 81 and hollow beads 82 are alternately distributed. The hollow beads 82 are fragile and contain glue inside. The grooves 23 are larger than the outer diameter of the limiting beads 81 and hollow beads 82.

[0043] When the fixing rebar 3 is inserted into the buckle 2, the pull rope 8 is wrapped around the outer wall of the fixing rebar 3. The inner wall of the buckle 2 and the fixing rebar 3 work together to crush the hollow bead 82, causing the glue to overflow. The limiting bead 81 is partially embedded in the groove 23. The glue bonds the inner wall of the buckle 2, the limiting bead 81, and the outer wall of the fixing rebar 3. Since the outer wall of the fixing rebar 3 has ribs, the ribs and the limiting bead 81 work together to further increase the friction between the inner wall of the buckle 2 and the fixing rebar 3, thereby improving the fixing effect.

[0044] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
