Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a concrete pouring interception device for the core area of a beam and column. Background Art
[0002] The core area of the beam-column node is the area where the beam and column meet. It is the node area where the beam and column meet. When pouring the core area of the beam and column, concrete of different grades are used for pouring. Therefore, a concrete pouring interception device for the core area of the beam and column is required during pouring.
[0003] The traditional interception device for concrete pouring in the core area of beams and columns is usually carried out by workers on site to tie the wire mesh. Due to the loose connection between the work processes of various types of work, it is easy for the workers to tie the wire mesh when the beam side formwork has been installed, resulting in the inability to complete the interception measure. If it is to be completed, the side formwork needs to be removed and then closed after the construction is completed; when there is a densified area at the end of the beam (spacing is 100mm) and there are multi-legged hoops, twist bars, and hooks, the workers' construction efficiency reduction behavior will be more obvious; due to the small construction space, the operators tie the wire mesh with poor quality during construction, and when pouring concrete, the concrete is likely to break off the wire mesh, resulting in poor construction quality, low construction efficiency and long construction period. For this reason, we propose a concrete pouring interception device for the core area of beams and columns. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-4 The utility model provides a technical solution: a concrete pouring interception device for the core area of a beam and column, comprising a beam stirrup 1, wherein a mesh frame unit 2 for concrete pouring interception is arranged inside the beam stirrup 1, and the mesh frame units 2 are three.
[0018] It should be noted that the mesh skeleton unit 2 is composed of a keel 6 and two layers of steel mesh 7. By arranging the keel 6 outside the steel mesh 7, it can be ensured that the concrete is not deformed during pouring and the mesh surface fits more closely.
[0019] The inner wall of the beam stirrup 1 is located outside the mesh skeleton unit 2 and is evenly and fixedly connected with the first beam main reinforcement 3. The third beam main reinforcement 5 is arranged on the surface of the mesh skeleton unit 2 inside the beam stirrup 1. The point between the mesh skeleton unit 2 and the first beam main reinforcement 3 forms a wire mesh tying point 10. The mesh skeleton unit 2 includes a keel 6 and a wire mesh 7. The outside of the keel 6 is tied with a wire mesh 7.
[0020] It should be noted that the utility model has a beam cross-sectional size of 400*600 according to the field test, and needs to be equipped with three keels 6 and covered with wire mesh 7 for double-layer tying. When equipping the keel 6, each keel 6 needs two first round steels 8 and four second round steels 9. The four second round steels 9 are welded between the two first round steels 8 at equal intervals, and the ends of the two second round steels 9 located at both ends of the first round steels 8 are welded and fixed to the ends of the first round steels 8. The equipped keel 6 forms a mesh-shaped structure as a whole, and then the wire mesh 7 is tied to both sides of each keel 6 in turn, so that the wire mesh 7 covers the edge of the keel, the edge is locked tightly, and the edge is tied firmly, so that the mesh frame unit 2 is equipped. Three mesh frame units 2 are equipped, and a beam is fixed on the outside of the main reinforcement 3 of the first beam. Stirrups 1, three mesh skeleton units 2 are set in the beam stirrups 1, the mesh skeleton units 2 are placed horizontally and fixed on the beam stirrups 1, the upper part of the mesh skeleton unit 2 is fixed on the previous beam stirrup 1 along with the beam stirrups 1, and after the next beam stirrup 1 is installed, the lower end of the mesh skeleton unit 2 is fixed on the top of the next beam stirrup 1 to form a 45° angle, and so on to form a 45° interception of the entire beam section, and the mesh skeleton unit 2 is tied and fixed according to its designed position. After tying, the gap between the mesh skeleton unit 2 and the oblique section of the beam stirrup 1 is small, which ensures the flatness of the interception surface, and double strands of No. 22 wire are used to tie and fix the beam stirrup 1 and the third beam main reinforcement 5 to ensure that the position of the mesh skeleton unit 2 is correct and does not move during the concrete pouring process.
[0021] The keel 6 has an overall structure in the shape of a U-shaped letter "J". The keel 6 includes a first round steel 8 and a second round steel 9. There are two first round steels 8, and the two first round steels 8 are symmetrically arranged. There are four second round steels 9, and the four second round steels 9 are equidistantly fixedly connected between the two first round steels 8.
[0022] It should be noted that each keel 6 requires two first round steels 8 and four second round steels 9, so that the keel 6 does not need to be prepared on site and can be prepared in advance for use.
[0023] Two ends of the four second round steels 9 are respectively fixed to the two first round steels 8 by welding.
[0024] It should be noted that the four second round steels 9 are welded between the two first round steels 8 at equal intervals, so that the keel 6 is more stable as a whole and has better supporting strength.
[0025] The wire mesh 7 is located on one side of the keel 6 , and the wire mesh 7 is fixed to the outside of the keel 6 by means of binding wires.
[0026] It should be noted that the assembled keel 6 is in a mesh-shaped structure as a whole, and then the wire mesh 7 is tied to one side of each keel 6 in turn, so that the wire mesh 7 covers the edge of the keel 6, the edge is tightly locked, and the edge is firmly tied, so that the mesh skeleton unit 2 is assembled.
[0027] The first round steel 8 and the second round steel 9 are both No. 6 round steels.
[0028] It should be noted that the first round steel 8 and the second round steel 9 both use No. 6 round steel as the keel 6, and the wire mesh 7 covers all edges of the keel 6 and is tied firmly, so that the mesh skeleton unit 2 does not need to be tied at the construction site and can be directly equipped and placed at the construction site for use.
