Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a grounding point construction structure for preventing side lightning strikes on high-rise buildings. Background Art

[0002] At present, the grounding of the exterior wall metal components of high-rise buildings (such as doors, windows, guardrails, curtain walls, etc.) is to directly weld a reserved flat steel as the grounding point on the grounding down conductor (the steel bar inside the column welded to the equalizing ring of the ring beam). The specific construction method is: one end of the flat steel is welded to the grounding down conductor, and the other end is bent and simply fits the formwork by utilizing the elastic deformation of the flat steel. This construction structure is not conducive to the construction of the formwork, because the formwork needs to overcome the elastic deformation of the flat steel to be properly constructed; in addition, it may also happen that the carpenters will bend the flat steel into the column in order to build the formwork, so that after the pouring is completed, the position of the flat steel cannot be found, and the flat steel needs to be destructively found later to complete the grounding.

[0003] Conventional methods also involve installing junction boxes on flat steel. However, these require securing the junction boxes to the main internal reinforcement using multiple steel bars. Furthermore, the precise fit of the junction boxes to the formwork must be ensured, and the position of the junction boxes cannot be adjusted once secured. Consequently, this existing construction method using junction boxes presents complex construction operations, low efficiency, and significant difficulty in pre-embedded positioning of the junction boxes.

[0004] Based on this, the utility model provides a high-rise building side lightning protection grounding point construction structure with convenient and quick construction. Utility Model Content

[0029] Example 1

[0030] This embodiment provides a high-rise building side lightning protection grounding point construction structure, as shown in the attached Figure 1 To the attached Figure 3 As shown, it includes column reinforcement 1, round steel 2, junction box 3 and fixing bracket 4, wherein:

[0031] As attached Figure 1 and attached Figure 3 As shown, at least one steel bar 1 in the column is welded to the equalizing ring 10 of the building ring beam as a grounding down conductor, and one end of the round steel 2 is welded to the grounding down conductor. Figure 2 and attached Figure 3 As shown, the fixing bracket 4 includes an upper crossbeam 4.1, a lower crossbeam 4.2, a connecting plate 4.3 connecting the upper crossbeam 4.1 and the lower crossbeam 4.2 at both ends, and a sleeve 4.4 welded through the middle of the connecting plate 4.3. Figure 2 As shown, the bottom of the junction box 3 is provided with a flanged hole 3.1 that plugs into the sleeve 4.4. A nut 3.2 is rotatably mounted on one end of the flanged hole 3.1, which is located inside the box. The nut 3.2 is threadedly connected to the sleeve 4.4. During assembly of the junction box and the fixed bracket, the flanged hole of the junction box is aligned with the sleeve of the fixed bracket, and the nut is inserted and tightened. This structure allows the position of the junction box on the sleeve to be adjusted using the nut. To ensure the stability of the junction box during adjustment, this embodiment includes guide ribs 4.5 on the upper crossbeam 4.1 and / or lower crossbeam 4.2 of the fixed bracket 4. Correspondingly, rib-through plates 3.3 are provided at the top and bottom of the junction box 3, which flexibly engage with the guide ribs 4.5. This structural design prevents the junction box from rotating during adjustment. To ensure the stability of the junction box after adjustment and prevent movement during concrete pouring and vibration, this embodiment further includes a locking screw 3.4 on the nut 3.2, which locks the junction box into place.

[0032] As attached Figure 1 and attached Figure 2 As shown, the other end of the round steel 2 passes through the sleeve 4.4 and enters the junction box 3. Figure 1 and attached Figure 3 As shown, the round steel 2 is bent into shape by a welding portion 2.1, a bent portion 2.2 and a plug-in portion 2.3. The welding portion 2.1 is welded to the grounding down conductor, and the plug-in portion 2.3 passes through the sleeve 4.4 and enters the junction box 3.

[0033] Preferably, as attached Figure 4 As shown, the ends of the upper and lower crossbeams 4.1 and 4.2 are equipped with C-shaped clips 4.6 that interlock with the column reinforcement 1. This clip-on design allows the fixing bracket to be quickly installed on the column reinforcement. The junction box is positioned by the support provided by the round steel and the clip-on connection between the fixing bracket and the column reinforcement. Furthermore, the ends of the upper and lower crossbeams are interlocked with the column reinforcement and then tied together, further ensuring the structural stability of the junction box installation.

[0034] Preferably, as attached Figure 2 As shown, a screw hole 2.3.1 is provided at the end of the plug-in portion 2.3 of the round steel 2, and the grounding connection wire 5 is provided in the junction box 3, with one end thereof being fixed in the screw hole of the plug-in portion by a screw.

[0035] Preferably, the junction box 3 is further filled with foam 6, which extends 1 to 7 mm beyond the junction box. A groove is formed on one side of the foam 6 toward the bottom of the box to accommodate the recessed sleeve. The foam has a certain degree of elasticity, which can eliminate the gap between the junction box and the formwork and prevent concrete castables from entering the junction box.

[0036] The specific construction steps are as follows:

[0037] 1. Welding round steel: According to the designed position of the grounding point, weld one end of the bent round steel to the grounding down conductor;

[0038] 2. Install the junction box: Install the junction box on the fixed bracket, align the sleeve of the fixed bracket with the plug-in end of the round steel, and buckle the upper and lower beams of the fixed bracket to the steel bars in the column, and tie the upper and lower beams;

[0039] 3. Adjust the position of the junction box: According to the requirements of the template construction, adjust the position of the junction box, lock the locking screws after adjustment, and put filling foam in the junction box;

[0040] 4. Build formwork 20, pour concrete, remove formwork, and remove filling foam.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
