Technical Field

[0001] The utility model relates to the technical field of cantilever scaffolding construction, in particular to a cantilever frame anchoring node structure in a drop plate area of ​​a building. Background Art

[0002] In residential construction projects, cantilever scaffolding is often used for external construction frames. To ensure the safety of cantilever scaffolding, the stable anchoring of the cantilever I-beam beam, which is the main beam of the cantilever scaffolding, is crucial. Due to architectural design requirements, drop-off areas often appear in the structure, resulting in height differences in the supporting plane of the I-beam, making it difficult to form a reliable bottom plane support. In the drop-off area, when constructed in the traditional way, it is usually necessary to use long wooden planks at the anchor point to pad the I-beam, lengthen the U-shaped clamp used for fixing accordingly, and use wooden wedges on both sides of the U-shaped clamp to tighten it. However, the support method of raising the I-beam and padding it with long wooden planks is not very reliable, and the height of the wooden planks is difficult to accurately control. In addition, the wooden wedges used for tightening on both sides are prone to loosening, which not only makes the construction process too cumbersome, but also poses a safety hazard.

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.

[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 1-6 , the preferred embodiments of the utility model are further described in detail:

[0023] like Figure 1As shown, the utility model preferably adopts a cantilever anchor node structure of a building drop plate area, including an anchor screw 1, a card plate 3 and a steel pad 9, the anchor screws 1 are arranged in pairs, and the two anchor screws 1 arranged in pairs are correspondingly arranged on both sides of the cantilevered I-beam 5, and the anchor screws 1 penetrate the structural floor slab 7 at the embedded sleeve 6 arranged in the structural floor slab 7, the card plate 3 is correspondingly arranged on both sides of the top and bottom of the cantilevered I-beam 5, and the cross-section of the card plate 3 is in the shape of a "J", and a card groove matching the cantilevered I-beam 5 is arranged in the middle of the plate body, and the end wing plate of the cantilevered I-beam 5 is clamped in the card groove of the card plate 3, and anchor holes 12 matching the anchor screws 1 are opened on both sides of the plate body of the card plate 3. 3 is sleeved on the paired anchor screws 1 through the anchor holes 12 on both sides and is locked and fixed by nuts 4; the steel pad 9 is attached to the bottom end surface of the structural floor slab 7, and anchor holes 12 matching the anchor screws 1 are opened on both sides of the plate body. The steel pad 9 is sleeved on the paired anchor screws 1 through the anchor holes 12 on both sides and is locked and fixed by nuts 4. Since the clamping plate 3 is locked on the anchor screws 1 through nuts 4, the fixing position of the clamping plate 3 can be adaptively adjusted according to the actual design height of the cantilevered I-beam 5, and the upper and lower clamping plates 3 can effectively clamp the cantilevered I-beam 5 so that the cantilevered I-beam 5 in the suspended state can still be effectively anchored;

[0024] Considering that the clamping plate 3 below the cantilevered I-beam 5 is also in a suspended state, on this basis, in order to further improve the anchoring stability of the cantilevered I-beam 5, a steel pressure plate 2 can be added to the outer side of the clamping plate 3, such as Figure 2-3 As shown, the steel pressure plate 2 is correspondingly arranged on the side of the card plate 3 away from the cantilevered I-beam 5, and the steel pressure plate 2 is close to the bottom of the card plate 3 card slot, and the plate body is provided with anchor holes 12 matching the anchor screws 1 on both sides. The steel pressure plate 2 is sleeved on the paired anchor screws 1 through the anchor holes 12 on both sides and is locked and fixed by nuts 4. After the steel pressure plate 2 is added, the steel pressure plate 2 and the card plate 3 can form a force-bearing whole, so as to better clamp the cantilevered I-beam 5 and avoid the loosening problem that is easy to occur when only the nuts 4 on the outer side of the card plate 3 bear the force;

[0025] like Figure 2-5 As shown, on this basis, in order to make the integrity of the clamping plate 3 and the steel pressing plate 2 better, it is appropriate to fix a plurality of limit rods 10 at intervals on the side of the clamping plate 3 away from the cantilevered I-beam 5, and a limit hole 11 matching the limit rod 10 is opened at the position of the steel pressing plate 2 corresponding to the limit rod 10. When installed in place, the limit rod 10 is inserted into the limit hole 11, which can effectively avoid the relative sliding problem between the clamping plate 3 and the steel pressing plate 2;

[0026] Of course, in order to realize the node structure installation more conveniently and quickly, the corresponding nut 4 only needs to be set on the side of the steel pressure plate 2, the card plate 3 and the steel pad 9 away from the cantilevered I-beam 5. At this time, in order to better realize the anchoring of the cantilevered I-beam 5, the steel pressure plate 2 and the steel pad 9 can be locked and fixed by double nuts 4 to avoid the problem of loosening of the nut 4. At the same time, the galvanized gasket 8 can be added to the side where the nut 4 is connected to each plate according to actual needs to further improve the locking effect;

[0027] In order to increase the contact area between the clamping plate 3 and the cantilevered I-beam 5, so that the cantilevered I-beam 5 can be more stably clamped in the clamping groove of the clamping plate 3, and to make the clamping plate 3 clamp the I-beam 5 as well as possible, the setting length of the clamping plate 3 can be appropriately increased, that is, the extension length of the clamping plate 3 along the axial direction of the cantilevered I-beam 5 is greater than the extension length of the steel pressure plate 2 along the axial direction of the cantilevered I-beam 5, and each clamping plate 3 is clamped and fixed by at least two spaced steel pressure plates 2, for example, Figure 4-6 As shown, the steel plate 9 and the clamping plate 3 are both provided with four anchor holes 12, that is, the steel plate 9 and the clamping plate 3 are both supported by four anchor screws 1 to avoid the problem of plate surface tilting when supported by two anchor screws 1.

[0028] The construction process of the utility model is as follows:

[0029] First, by pre-embedding the PVC sleeve as the embedded sleeve 6 in the cast-in-place structural floor 7, after the cast-in-place concrete structural floor 7 is poured and reaches the design strength, the anchor screw 1 is inserted into the embedded sleeve 6, and the steel pad 9 and the galvanized gasket 8 are used to fix the lower part of the anchor screw 1 with double nuts 4, and then, another set of double nuts 4 are screwed into the anchor screw 1 at the top of the anchor screw 1, and then the galvanized gasket 8 and the steel pressure plate 2 are placed in sequence, and the "X"-shaped card plate 3 is inverted and inserted into the anchor screw 1, and it is ensured that the limit rod 10 on the "X"-shaped card plate 3 is inserted into the limit rod on the lower steel pressure plate 2 After being fixed in the hole 11, the cantilevered I-beam 5 is placed in the slot of the I-shaped clamping plate 3, and then the upper I-shaped clamping plate 3 is installed, and the two sides are tightened and fixed to the anchor screw 1 with galvanized gaskets 8 and single nuts 4. Next, the steel pressure plate 2 is inserted into the anchor screw 1, and it is ensured that the limiting holes 11 on the steel pressure plate 2 are aligned and connected with the limiting rods 10 on the I-shaped clamping plate 3, and then the two sides of the steel pressure plate 2 are tightened and fixed to the anchor screw 1 with galvanized gaskets 8 and double nuts 4, forming a force-bearing whole suitable for the lowering plate, which is used for anchoring and fixing the cantilevered I-beam 5 in the lowering plate area.

[0030] 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.
