Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an anti-falling structure for removing keels of exterior wall templates. Background Art

[0002] As a formwork method to improve efficiency and shorten construction period, the external wall formwork required the cooperation of multiple people in the process of removing the external formwork steel pipe main keel after pouring concrete on the shear wall. During the construction process, additional personnel need to be added to the external scaffolding to cooperate in the removal of the steel pipe main keel and transfer it to a safe location. Workers stand on the external scaffolding to remove the formwork and transfer the steel pipe main keel, which poses a great safety hazard and affects construction efficiency: due to the location of the external shear wall, as the construction floor increases, the steel pipe main keel may accidentally slip during the removal process, causing the risk of falling from a height. Summary of the invention

[0003] The utility model aims to provide an anti-falling structure for removing the keel of an exterior wall formwork, which can improve work efficiency, reduce the risk of falling from height, and reduce potential safety hazards in construction.

[0004] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0005] The utility model discloses a structure for preventing the removal of the keel of an exterior wall formwork, comprising an exterior wall formwork, on which a plurality of secondary keel square timbers are longitudinally arranged at intervals, and a plurality of groups of steel pipe main keels are horizontally arranged at intervals from top to bottom on the outside of the secondary keel square timbers, the steel pipe main keels are fixedly connected to the exterior wall formwork by tension bolts, and a plurality of anti-fall devices are arranged at intervals on each group of the steel pipe main keels, the anti-fall devices are used to prevent the steel pipe main keels from falling after the tension bolts are removed, and after the tension bolts are removed, the steel pipe main keels are supported by the anti-fall devices, and there is no need to arrange additional personnel to cooperate in supporting the steel pipe main keels by hand. The operating personnel only need to remove the nuts on the tension bolts on the inner wall with tools, and at this time, if the loose steel pipe main keel on the outside accidentally slips, it will automatically fall into the anti-fall device, and the device serves to place the steel pipe main keel.

[0006] Furthermore, the anti-fall device includes a horizontal bottom plate, which is placed at the bottom of the steel pipe main keel. The inner end of the horizontal bottom plate is fixedly connected to the secondary keel square wood, and a vertical baffle is provided on the upper part of the outer end. The horizontal bottom plate serves to place the steel pipe main keel. When the steel pipe main keel rolls outward, the vertical baffle can play a blocking role to prevent the steel pipe main keel from sliding outward.

[0007] Furthermore, a reinforcing cross plate is provided on the top of the vertical baffle, and the inner end of the reinforcing cross plate is fixedly connected to the secondary keel square wood, so as to further enhance the overall supporting strength.

[0008] The utility model has the advantage that the anti-fall device is fixed on the secondary keel square wood of the exterior wall formwork. When the exterior wall formwork is dismantled, there is no need to arrange additional personnel to hold the steel pipe main keel with hands. The operator only needs to use tools to remove the nuts on the tension bolts on the inner wall. At this time, if the loose steel pipe main keel on the outside accidentally slips, it will automatically fall into the anti-fall device, so the steel pipe main keel can be placed without frequent dismantling and transfer, which saves labor, improves construction efficiency, shortens construction period, and reduces the risk of falling from height. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0010] 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 of 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.

[0011] like Figure 1 As shown, the exterior wall formwork keel removal anti-falling structure described in the utility model comprises an exterior wall formwork 10, on which a plurality of secondary keel square timbers 20 are longitudinally arranged at intervals, and on the outside of the secondary keel square timbers 20, a plurality of groups of steel pipe main keels 30 are horizontally arranged from top to bottom at intervals, each group of steel pipe main keels 30 is fixedly connected to the exterior wall formwork by tension bolts 40, and an anti-falling device is horizontally arranged at intervals of 1 meter on each group of steel pipe main keels 30, and the vertical direction of the anti-falling device is arranged according to the number of steel pipe main keels 30;

[0012] Specifically, the anti-fall device is composed of a horizontal bottom plate 50, a vertical baffle plate 60 and a reinforced horizontal plate 70. The horizontal bottom plate 50 is placed at the bottom of the steel pipe main keel 30. The horizontal bottom plate 50 and the reinforced horizontal plate 70 are both horizontally arranged, and their inner ends are respectively fixed to the secondary keel square wood 20 by nails. A vertical baffle plate 60 is arranged between the outer ends of the horizontal bottom plate 50 and the reinforced horizontal plate 70.

[0013] Its working principle is: the anti-fall device is fixed on the secondary keel square wood 20 of the exterior wall formwork 10. When the exterior wall formwork 10 is dismantled, there is no need to arrange additional personnel to hold the steel pipe main keel 30 by hand. The operator only needs to use tools to remove the nuts of the tension bolts 40 on the inner wall. At this time, if the loose steel pipe main keel 30 on the outside accidentally slips, it will automatically fall into the anti-fall device, and the steel pipe main keel 30 can be placed, reducing the number of times the formwork material is transported, avoiding multiple dismantling, saving labor, improving construction efficiency, shortening construction period, and reducing the risk of falling from height.
