Technical Field

[0001] The utility model relates to the technical field of building welding construction, in particular to a scalding-proof fire-joining bucket for roofing engineering. Background Art

[0002] The roofing project of special-shaped venues is different from the conventional roofing project. Due to the novel and complex facade shape of venues, conventional vertical lock-edge mechanical waterproofing cannot be used. Only TPO flexible waterproofing can be used. There is basically a decorative surface layer above the roof waterproofing layer. The fixed support points of the decorative surface layer need to be rooted and fixed on the purlin keel, which inevitably requires penetrating the TPO flexible waterproofing layer. After the TPO construction is completed, the keel support points still need to be welded. TPO anti-scalding is particularly important. However, since the purlin keel needs to form a puncture point in the middle of the fire connection device, the existing fire connection device has defects to varying degrees in terms of installation difficulty and protection effect, and it is difficult to meet the welding and fire connection requirements of the purlin keel above the TPO flexible waterproofing layer.

Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-4 , the preferred embodiments of the utility model are further described in detail:

[0023] like Figure 1-4 As shown, the utility model is preferably a fire-receiving bucket for preventing scalding of roofing engineering, comprising a fire-receiving bucket 1 and a drawer plate 4, wherein a long strip-shaped notch 2 for the purlin keel 8 to pass through is provided on the bucket body of the fire-receiving bucket 1, wherein the width of the notch 2 matches the outer diameter of the purlin keel 8, and the inner edge thereof is provided as a groove matching the outer shape of the purlin keel 8, wherein the notch 2 extends outward from the middle of the bucket body bottom plate of the fire-receiving bucket 1 and passes through the bucket body side plate of the fire-receiving bucket 1 to communicate with the outside, and a notch 3 is correspondingly provided at the bottom of the bucket body side plate of the fire-receiving bucket 1 on both sides of the notch 2;

[0024] The drawer board 4 is penetrated at the notch 3, and its board width is greater than the opening width of the notch 2. The inner edge of its bottom plate is provided with a groove matching the shape of the purlin keel 8, and its bottom plate is attached to the bottom plate of the fire receiving bucket 1. The bottom plate of the drawer board 4 is penetrated at the notch 3 and is clamped by the side plate and bottom plate of the fire receiving bucket 1 at the notch 3. When an external force is applied to the drawer board 4, the drawer board 4 can slide inward and outward along the direction of the notch 2. In order to facilitate the push and pull operation of the drawer board 4, a handle 5 can be fixedly provided on the side plate of the drawer board 4 for the convenience of the operator to hold it;

[0025] Since the top of the puncture point where the purlin keel 8 penetrates the TPO needs to be welded, the fire bucket 1 cannot be lowered from the top of the purlin keel 8. Therefore, a long strip notch 2 is opened on one side of the fire bucket 1 to insert the fire bucket 1 into the purlin keel 8 so that the fire bucket 1 can hold the puncture point to prevent welding sparks from falling and scalding the TPO. When installing the fire bucket 1, first pull out the drawer board 4 as a whole to open the notch 2, align the notch 2 of the fire bucket 1 with the purlin keel 8, move the fire bucket 1 and put it on the purlin keel 8, then penetrate the drawer board 4 from the notch 3 and push the drawer board 4 inward. Push in, when the drawer board 4 slides to the innermost position, the side plate of the drawer board 4 is close to the side plate of the fire bucket 1 so that the gap 2 at the side plate of the fire bucket 1 is effectively blocked, and the bottom plate of the drawer board 4 closes the gap 2 outside the purlin keel 8 to prevent welding sparks from falling from the gap 2. Since the drawer board 4 and the inner edge of the gap 2 are both provided with grooves that match the shape of the purlin keel 8, therefore, when the drawer board 4 is installed in place, the inner edge of the bottom plate of the drawer board 4 and the bottom plate of the fire bucket 1 at the inner edge of the gap 2 will cooperate to clamp the purlin keel 8, ensuring that no large gap will appear around the purlin keel 8.

[0026] Taking into account that the inner edge of the drawer board 4 may be warped and cannot be stably attached to the bottom plate of the fire receiving bucket 1, and the vertical gaps of the purlin keel 8 are prone to molten iron leakage, in order to prevent the molten iron from flowing down from the gaps between the purlin keel 8 and the surrounding side during welding and scalding the TPO, a shielding box 6 is further provided on the purlin keel 8. The shielding box 6 is sleeved on the purlin keel 8 above the fire receiving bucket 1. The shielding box 6 is a two-flap structure. The two-flap shielding box 6 is buckled on both sides of the purlin keel 8 to form a closed box body. The shielding box 6 is placed on the bottom plate of the fire receiving bucket 1. On, the seams between the purlin keel 8 and the bottom plate of the fire bucket 1, and the seams between the purlin keel 8 and the drawer board 4 are covered and shielded. The height of the shielding box 6 needs to be less than the height of the side plate of the fire bucket 1 to prevent the dripping welding sparks from splashing to the outside of the fire bucket 1 and scalding the TPO. Of course, magnetic buckles 7 can be added to the joints of the two-flap shielding box 6. The magnetic buckles 7 on the two-flap shielding box 6 are correspondingly adsorbed and fixed, and the two-flap shielding box 6 forms a closed box body to prevent the shielding box 6 from being detached from the purlin keel 8 due to accidental disturbance during construction, resulting in a decrease in the protection effect.

[0027] In order to further improve the fire connection effect, fireproof cotton is laid in the fire connection bucket 1. The fireproof cotton is wrapped around the purlin keel 8 and fixed on the purlin keel 8 through a cable tie. The outer edge of the fireproof cotton extends from the purlin keel 8 to the side plate of the bucket body of the fire connection bucket 1, covering the entire shielding box 6 and the bottom plate of the bucket body of the fire connection bucket 1. After the fireproof cotton (preferably 50 mm thick) is padded, sprinkle an appropriate amount of water on the fireproof cotton to further prevent sparks from flying and effectively catch welding sparks.

[0028] After the welding operation at the current purlin keel 8 position is completed, the fireproof cotton and the shielding box 6 are removed in turn, the welding slag on the fireproof cotton is stored in the designated position, and the drawer plate 4 is pulled out, and then the fire bucket 1 is removed from the purlin keel 8 along the notch 2 and transferred to the next construction position.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
