Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially to a post-pouring belt steel bar anchoring structure. BACKGROUND

[0002] In building construction, the post-pouring belt is an important structural measure, mainly used to prevent harmful cracks in reinforced concrete structures caused by uneven shrinkage or uneven settlement. It is a concrete belt reserved at the corresponding position of large-area super-long seamless concrete structures according to design or construction specification requirements. The role of the post-pouring belt is to temporarily divide the structure into several parts, and after the internal shrinkage of the component is completed, the construction joint concrete at the post-pouring belt is poured within the specified time, thereby connecting the structure as a whole.

[0003] The construction quality control of the post-pouring belt is crucial. Non-shrinkage concrete should be used during concrete pouring, and the strength grade should be one level higher than that of the original concrete to ensure the close combination of new and old concrete. At the same time, the post-pouring belt's formwork, cleaning, steel bar resetting, and concrete vibrating links need to be strictly controlled during construction to prevent quality problems caused by construction errors. If the post-pouring belt construction quality cannot be effectively controlled, it will affect the structural strength of the post-pouring belt and reduce its durability. Therefore, optimizing the steel bar arrangement and anchoring design to ensure the accuracy of the construction process is an important measure to improve the construction quality of the post-pouring belt.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0037] With reference to the drawings, Figures 1-4 The embodiment provides a post-poured strip steel bar anchoring structure, which comprises an anchor steel bar 100, an anchor block 200 and a hanging piece 300, at least one set of anchor blocks 200 is arranged at the long direction of two ends of the anchor steel bar 100 respectively, the anchor block 200 is slidably connected with the anchor steel bar 100; at least one set of hanging pieces 300 is arranged at the radial direction of two sides of the anchor steel bar 100 respectively, the hanging piece 300 is movably connected with the anchor block 200, and the hanging piece 300 can be close to or away from the anchor block 200.

[0038] The layout direction of the anchoring steel bars 100 is that the anchoring steel bars 100 extend along the width direction of the post-pouring belt. The steel bar mesh at the post-pouring belt position includes long-direction steel bars and width-direction steel bars, the anchoring steel bars 100 can completely replace the original width-direction steel bars, or the anchoring steel bars 100 can be additionally arranged after the original width-direction steel bars are arranged, the anchoring steel bars 100 not only have the function of the original width-direction steel bars, but also have the function of connecting the anchoring blocks 200 and the hanging pieces 300. The hanging pieces 300 are used for connecting the anchoring blocks 200 and the steel bar meshes in the concrete structures on both sides of the post-pouring belt, and stabilizing the positions of the anchoring blocks 200, the anchoring blocks 200 arranged at the long-direction two ends of the anchoring steel bars 100 are respectively embedded in the concrete structures on both sides of the post-pouring belt, and can significantly enhance the gripping force between the steel bars and the concrete in cooperation with the anchoring steel bars 100, and the design can effectively transmit stress and reduce the risk of cracks caused by concrete shrinkage or temperature change.

[0039] In implementation, the number of the anchoring steel bars 100 can be configured according to specific requirements, for example, two rows and two columns of anchoring steel bars 100 are uniformly arranged in the embodiment, which can improve the connection stability with the steel bar mesh.

[0040] Reference is made to the accompanying drawings Figure 4 The hanging piece 300 includes a mounting plate 310, a hanging plate 320 and a distance adjusting bolt 330, the mounting plate 310 is located between the hanging plate 320 and the anchoring block 200, the hanging plate 320 is fixedly connected with the hanging plate 320, and the distance adjusting bolt 330 penetrates through the mounting plate 310 to connect the anchoring block 200, and is used for adjusting the distance between the hanging plate 320 and the anchoring block 200 along the radial direction of the anchoring steel bar 100. The distance between the mounting plate 310 and the anchoring block 200 is changed by rotating the distance adjusting bolt 330, that is, the distance between the hanging plate 320 and the anchoring block 200 is changed, so as to adapt the anchoring structure to steel bar meshes with different densities.

[0041] The lateral side of the anchoring block 200 should be provided with the internally threaded groove 210 for installing the distance adjusting bolt 330, and the mounting plate 310 should be provided with screw holes corresponding to the positions of the internally threaded groove 210. In use, the distance adjusting bolt 330 is first installed into the screw hole, with the cap end of the distance adjusting bolt 330 abutting against the plate surface of the mounting plate 310 (especially the plate surface connected with the hanging plate 320), and then the rod end of the distance adjusting bolt 330 is inserted into the internally threaded groove 210, and the distance adjusting bolt 330 is rotated by a tool to a specified length inserted into the internally threaded groove 210. Since the cap end of the distance adjusting bolt 330 originally abuts against the plate surface of the mounting plate 310, the cap end of the distance adjusting bolt 330 pushes the mounting plate 310 to be close to the anchoring block 200 during the rotation of the distance adjusting bolt 330, thereby driving the hanging plate 320 to be close to the anchoring block 200. The specified length is determined according to the distance between the two steels in the reinforcement net, which is not limited here. In this way, the anchoring structure can be shaped and mass-produced, and the distance between the hanging plate 320 and the anchoring block 200 can be adjusted according to the distance between the two steels in the reinforcement net during use, which greatly reduces the cost.

[0042] To make the adjustment operation of the distance between the mounting plate 310 and the anchoring block 200 more smooth, the mounting plate 310 is provided with a guide sliding rod 340 in this embodiment, the guide sliding rod 340 is in sliding connection with the anchoring block 200, and is used to guide the movement of the mounting plate 310. The guide sliding rod 340 extends in the same direction as the distance adjusting bolt 330, and the lateral side of the anchoring block 200 should be provided with a sliding groove 220 for installing the guide sliding rod 340. If the mounting plate 310 is tilted, it will increase the difficulty of rotating the distance adjusting bolt 330 in the internally threaded groove 210, but the guide sliding rod 340 and the distance adjusting bolt 330 can cooperate with each other to make the mounting plate 310 always perpendicular to the axial direction of the internally threaded groove 210, so that the distance adjusting bolt 330 can rotate smoothly.

[0043] The number and distribution of the guide sliding rod 340 can be configured according to actual use requirements, which is not limited here. Preferably, the guide sliding rod 340 and the distance adjusting bolt 330 are uniformly distributed on the plate surface of the mounting plate 310.

[0044] Reference is made to the accompanying drawings Figure 4 The hanging plate 320 includes a first plate portion 321 and a second plate portion 322, the first plate portion 321 is parallel to the mounting plate 310, and the second plate portion 322 connects the first plate portion 321 and the mounting plate 310. The first plate portion 321, the second plate portion 322 and the mounting plate 310 are connected in sequence to form a C-shaped groove with an opening downward, which is used to connect the steel in the reinforcement net.

[0045] In the above technical solution, preferably, the hanging piece 300 is arranged on both sides of each anchor block 200, so that the position of the anchor block 200 can be adjusted in two directions. Of course, the hanging piece 300 can be arranged on one side of each anchor block 200, and a fixed hanging plate 320 is arranged on the other side of the anchor block 200. During installation, the fixed hanging plate 320 is first connected with the steel bar mesh, and then the position of the hanging piece 300 on the other side is adjusted.

[0046] If further guarantee of the connection stability of the hanging plate 320 and the steel bar in the steel bar mesh is required during construction, and disturbance to the position of the hanging plate 320 during concrete pouring or vibrating is to be avoided, welding can be performed on part or all of the hanging plates 320 and the steel bar mesh in each anchor structure.

[0047] On the other hand, a plurality of limiting nuts 400 are threadedly sleeved on the outer wall of the anchor steel bar 100, and the limiting nuts 400 abut against the side wall of the anchor block 200, so as to limit the position of the anchor block 200 on the anchor steel bar 100. During implementation, the limiting nuts 400 can be arranged on the proximal end and the distal end of the two anchor blocks 200, so as to guarantee the reliability of the relative position of the anchor steel bar 100 and the anchor block 200. Of course, the limiting nuts 400 can also be arranged only on the proximal end or the distal end of the two anchor blocks 200. After the position of the limiting nut 400 is adjusted, the anchor block 200 and the limiting nut 400 are welded and fixed, so as to guarantee the reliability of the relative position of the anchor steel bar 100 and the anchor block 200.

[0048] Through the above technical solution, the distance between the two anchor blocks 200 can be adjusted according to the actual construction requirements (especially the size) of the post-pouring belt and the concrete structures on both sides of the post-pouring belt. In addition, the reliability of the relative position of the anchor block 200 and the anchor steel bar 100 can be guaranteed, the relative sliding between the anchor steel bar 100 and the concrete can be avoided, the overall strength and stability of the post-pouring belt are improved, and the structural problems caused by the mispositioning of the steel bar or the insufficient anchoring are effectively prevented.
