Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a safety device for working surface construction during the hoisting of a composite plate. Background Art

[0002] In the detailed design of the roof of the house building aluminum formwork system, since the top is a prefabricated composite plate structure, aluminum formwork is only set in the gaps between plates and the plate strips. Figure 1 As shown, there are multiple holes 2 in the middle of the aluminum mold 1. During construction, the composite board is hoisted onto the aluminum mold 1, and the composite board hoisted onto the aluminum mold 1 covers the holes 2. However, since there is a certain difference between the thickness of the general standard composite board and the required thickness of the house floor, construction workers are required to pour on the composite board after the composite board is hoisted to complete the construction of the floor. During construction, construction workers need to assist in the lifting of the composite board on the aluminum mold 1 so that the composite board can be lifted to a suitable position for easy pouring in the later stage. Since there are multiple holes 2 in the middle of the aluminum mold 1, construction workers need to be extra careful during construction. Once a person falls, it will be a huge safety accident and there will be great safety hazards. At the same time, since the current thickness of the composite board is far from the thickness required for construction, the composite board needs to be poured for the second time after the lifting of the composite board is completed. However, during the secondary pouring process, since the aluminum mold is at the bottom, the pouring slurry is prone to leakage during pouring, which will cause secondary polishing after the construction is completed. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a safety device for the construction of the working surface during the lifting of the composite slab in view of the deficiencies in the above-mentioned prior art. A comprehensive protection system is constructed by combining the finished steel safety net, angle steel and keel to seal the holes of the aluminum mold, so that the aluminum mold top plate forms a solid whole, thereby effectively preventing the occurrence of safety hazards. At the same time, the sealing stop slurry strip can effectively avoid leakage of slurry when casting the composite slab, reducing the secondary grinding after the construction is completed.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a safety device for working surface construction during the lifting of composite panels, comprising an angle steel axially fixed along the hole wall of an aluminum mold, a plurality of keels fixedly connected to the surface of the angle steel, a plurality of the keels and the angle steel enclose a plurality of rectangular areas arranged in a matrix, a steel safety net with the same cross-sectional size as the area enclosed by the angle steel is fixedly laid on each of the rectangular areas, the edge of the steel safety net is fixed on the angle steel, and a sealing stop-slurry strip is provided on the edge of the angle steel close to the aluminum mold.

[0005] Furthermore, the sealing stop-slurry strip is a rubber sealing stop-slurry strip.

[0006] Furthermore, the angle steel is an L-shaped plate bent downward in the horizontal direction, the bent end of the angle steel is fixedly connected to the hole wall of the hole, the keel is fixed to the bent end of the angle steel, and the steel safety net is fixed to the bent end of the angle steel.

[0007] Furthermore, a first through hole is provided at the bent end of the angle steel, and a second through hole corresponding to the position of the first through hole is provided on the surface of the aluminum mold. Threads are provided in both the first through hole and the second through hole, and the threads are threadedly connected to the bolts, and the part of the bolt located outside the first through hole is threadedly connected to a nut.

[0008] Furthermore, the aluminum mold has a structure that is bent downward in the horizontal direction at the edge of the hole, the second through hole is located at the bent end of the aluminum mold and passes through it, and the portion of the bolt located outside the second through hole is threadedly connected with a nut.

[0009] Furthermore, the steel safety net is integrally formed.

[0010] Furthermore, the keel is a steel keel.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The utility model provides a safety device for working surface construction during the hoisting process of the composite plate. A basic protection frame is built at the hole with angle steel and keels, and the hole area is completely closed with a steel safety net, thus constructing a comprehensive protection system to close the holes of the aluminum mold, so that the aluminum mold top plate forms a solid whole, thereby effectively preventing the occurrence of safety hazards;

[0013] The utility model provides a safety device for working surface construction during the lifting process of a composite plate, in which a sealing stop-slurry strip is arranged on the top edge of the angle steel. Since the sealing stop-slurry strip is in sealing contact with the plate surface of the composite plate, the sealing stop-slurry strip effectively prevents the problem of slurry leakage from the aluminum mold joint when the composite plate is cast.

[0020] like Figure 2-3 As shown, the utility model provides a safety device for working surface construction during the lifting of a composite plate, comprising an angle steel 4 axially fixed along the wall of a hole 2 of an aluminum mold 1, a plurality of keels 3 fixedly connected to the surface of the angle steel 4, a plurality of the keels 3 and the angle steels enclose a plurality of rectangular areas arranged in a matrix, a steel safety net 5 having the same cross-sectional size as the area enclosed by the angle steel 4 is fixedly laid on each of the rectangular areas, and the edge of the steel safety net 5 is fixed on the angle steel 4.

[0021] During construction, the safety device provided by the utility model is fixed on the hole 2 of the aluminum mold 1, that is, the angle steel 4 is firmly fixed on the wall of the hole 2 of the aluminum mold 1, and at the same time, a plurality of cross-arranged keels 3 are fixed on the angle steel 4, and the keels 3 are supported under the steel safety net 5, thereby improving the safety and stability of the steel safety net 5 fixed on the hole 2. Due to the support of the keels 3, the force under the steel safety net 5 is uniform. At the same time, combined with the stability of the steel material of the steel safety net 5, even if people stand on it, there is no risk of the steel safety net 5 breaking, thereby eliminating the safety risk of lifting the composite plate.

[0022] In the present invention, since the composite board needs to be poured again after the composite board is laid, in order to prevent the poured slurry from leaking during pouring, the present invention provides a sealing stop slurry strip 8 at the edge of the angle steel 4 close to the aluminum mold 1. Among them, the sealing stop slurry strip 8 in the present invention is a rubber sealing stop slurry strip. The safety device provided by the present invention is combined with the aluminum mold 1, and a water-stopping rubber strip is added to the angle steel 4 to stop slurry, solving the problem of later maintenance.

[0023] In the utility model, the fixed connection between the angle steel 4 and the hole 2 wall of the aluminum mold 1 can use bolts 7 and nuts 6, or pins and inserts, and the appropriate selection can be made according to the actual needs of the construction site.

[0024] In the present invention, the angle steel 4 is an L-shaped plate bent downward in the horizontal direction, the bent end of the angle steel 4 is fixedly connected to the hole wall of the hole 2, the keel 3 is fixed to the bent end of the angle steel 4, and the steel safety net 5 is fixed to the bent end of the angle steel 4. A first through hole is provided at the bent end of the angle steel 4, and a second through hole corresponding to the position of the first through hole is provided on the surface of the aluminum mold 1. Threads are provided in both the first through hole and the second through hole, and the threads are threadedly connected to the bolts 7, and the part of the bolts 7 located outside the first through hole is threadedly connected to the nuts 6. The present invention tightly fixes the angle steel 4 and the aluminum mold 1 by the bolts 7 and the nuts 6, so that the angle steel 4 is firmly fixed to the surface of the hole 2 of the aluminum mold 1.

[0025] At the same time, in order to increase the firmness of the surface of the hole 2 of the aluminum mold 1 and the angle steel 4, the aluminum mold 1 is horizontally bent downward at the edge of the hole 2, the second through hole is located at the bent end of the aluminum mold 1 and passes through it, and the part of the bolt 7 located outside the second through hole is threadedly connected with a nut 6.

[0026] In order to improve the safety and stability of the device provided by the utility model, the steel safety net 5 is integrally formed. The keel 3 is a steel keel.

[0027] In summary, a comprehensive protection system was successfully constructed by combining finished steel safety nets, angle steels and steel keels. This makes the aluminum formwork top plate a solid whole. On the lower angle steel, we opened holes of the same size and spacing based on the pin reinforcement holes on the side of the aluminum formwork. During the installation process, we used pins to tightly connect the angle steel to the aluminum formwork top plate to form a stable whole, thus eliminating potential safety risks.

[0028] In order to further improve the efficiency, we considered the possible flatness problem of the composite slab during the pouring process based on the actual situation on site. Due to the certain errors in the production of the composite slab, this may cause overflow and concrete misalignment around the edges. In order to solve this problem, we added recyclable rubber sealing stop strips around the angle steel as stop strips. This design not only improves the quality of the project, but also effectively reduces the additional costs caused by overflow and misalignment.

[0029] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
