Abstract
The utility model relates to a basement roof protection fixing device, including the built-in fitting, the built-in fitting includes the reinforcing bar that the level set up and the vertical screw rod of locating on the reinforcing bar, the reinforcing bar is located protective layer reinforcing bar net piece lower part, and the concrete layer of protective layer is laid on protective layer reinforcing bar net piece upper portion, and reinforcing bar net piece layer and concrete layer are stretched out on screw rod upper portion, and it is fixed with the part that exposes of screw rod to adopt the bolt head to fix the protection railing. The utility model has simple process principle and convenient operation; the cost is low and the utility is realized; after the basement roof waterproof protective layer is poured, the roof waterproof layer is prevented from being damaged due to the fact that expansion screws are used for fixing the protective railings; the material is easily obtained on site, and the waste steel bar can be fully utilized, so that the method accords with the green construction concept.
Description
Technical Field
The utility model relates to a civil engineering, specific basement roof protection fixing device that says so.
Background
In deep foundation pit engineering, due to the limitation of small construction engineering site and the like of a part of the construction engineering site, materials are often required to be stacked on a top plate of a basement, and a processing site and the like are arranged. According to the on-site safety civilized construction requirement, need to stack the place periphery at processing place and material and set up the protection railing, for work such as guaranteeing that later stage conveniently backfills, often take earlier to set up corresponding place after basement roof waterproofing and waterproof layer construction completion to guarantee later stage backfill work labour saving and time saving. However, in general, the fixing of the protection balustrade needs to use an expansion screw to pierce through the protection layer to fix the balustrade, and this method will destroy the waterproof layer and cause the hidden trouble of water seepage.
Disclosure of Invention
The utility model aims at overcoming prior art's defect, provide a basement roof protection fixing device, avoided executing to beat the roof waterproof layer that the fixed protection railing of inflation screw caused and destroyed.
In order to solve the technical problem, the utility model discloses a realize like this:
the utility model provides a basement roof protection fixing device which characterized in that: the embedded part comprises a horizontally arranged reinforcing steel bar and a vertically arranged screw rod on the reinforcing steel bar, the reinforcing steel bar is positioned on the lower portion of a protective layer reinforcing steel bar mesh, a concrete layer of a protective layer is laid on the upper portion of the protective layer reinforcing steel bar mesh, the upper portion of the screw rod extends out of a reinforcing steel bar mesh layer and a concrete layer, and the fixed protective handrail is fixed by adopting a bolt head and an exposed portion of the screw rod.
Basement roof protection fixing device, its characterized in that: the diameter of the steel bar is 8mm, and the steel bar is connected with the screw rod in a welding mode.
The utility model has the advantages that: the process principle is simple and convenient to operate; the cost is low and the utility is realized; after the basement roof waterproof protective layer is poured, the roof waterproof layer is prevented from being damaged due to the fact that expansion screws are used for fixing the protective railings; the material is easily obtained on site, and the waste steel bar can be fully utilized, so that the method accords with the green construction concept.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a use state diagram.
Detailed Description
As shown in fig. 1 and 2: the utility model provides a basement roof protection fixing device, includes the built-in fitting, the built-in fitting includes reinforcing bar 1 and the vertical screw rod 2 of locating on the reinforcing bar that the level set up, the reinforcing bar is located protective layer reinforcing bar net piece lower part, and the concrete layer 3 of protective layer is laid on protective layer reinforcing bar net piece upper portion, and reinforcing bar net piece layer and concrete layer are stretched out on screw rod upper portion, treat that the concrete layer intensity of protective layer reaches 75% back, will fix protection railing 4 and adopt the bolt head fixed with the exposure part of screw rod.
Furthermore, the diameter of the steel bar is 8mm, and the steel bar is connected with the screw rod in a welding mode.
The specific construction process comprises the following steps:
and welding the embedded part, wherein phi 8 steel bars are adopted in the horizontal direction, and screw rods are adopted in the vertical direction.
Before protective layer concrete is poured on a top plate of the basement, an embedded part is arranged at a position where a protective railing needs to be arranged, and embedded part reinforcing steel bars are arranged below a protective layer reinforcing steel bar mesh.
And pouring protective layer concrete, and fixing the shaped protective barrier by adopting bolt heads and the exposed part of the screw rods of the embedded parts after the strength of the concrete reaches 75%.
