Abstract
The utility model provides an outer facade safety plain net device of prefabricated construction, including last guardrail, lower guardrail and down tube, last guardrail and lower guardrail put up the drawknot bolt and box out and be connected through outer protection the on angle steel and high strength bolt and the former prefabricated concrete wallboard, down tube bottom be connected with time guardrail, drawn safe plain net between down tube top and the last guardrail. Last guardrail and lower guardrail all include the bottom connecting rod that a plurality of horizontal directions distribute side by side, every foundation portion connecting rod one end is boxed out through outer protection frame drawknot bolt on angle steel and high strength bolt and the former prefabricated concrete wallboard and is connected, the other end through the fastener be connected with with bottom connecting rod vertically vertical rod, the steel pipe is established ties a plurality of bottoms connecting rod and is formed the bottom and prevent guardrail bar, guardrail bar is prevented outside with a plurality of vertical rods series connection component to the steel pipe. The utility model discloses utilize on the former prefabricated concrete wallboard the box out method of setting up of the safe plain net of design of outer protection frame drawknot bolt, improve the factor of safety of high -rise building construction.
Description
Technical field
This utility model relates to construction preventer field, specifically a kind of precast construction alien invasion safety net device.
Background technology
During construction, in order to protect workman and the safety of roadside pedestrian, building outer wall is usually mounted with protective frame and safety net.When high-building construction, protective frame with floor promote, when bottom plain net is set up, without can junction point (compared with traditional scaffold), rely solely on building low layer setting protective frame and safety net protect, safety coefficient is low.
Utility model content
This utility model is in order to solve problem of the prior art, it is provided that a kind of precast construction alien invasion safety net device, utilizes outer protective frame drawknot bolt on former Prefabricated Concrete wallboard to box out the erection method of design safety plain net, the safety coefficient of raising high-building construction.
Including upper guardrail, lower guardrail and brace, described upper guardrail and lower guardrail are boxed out by angle steel and high-strength bolt protective frame drawknot bolt outer with on former Prefabricated Concrete wallboard and are connected, it is connected with lower guardrail bottom described brace, between brace top and upper guardrail, has drawn safety net.
Described upper guardrail and lower guardrail all include the bottom connector rails of some horizontal directions column distribution, boxed out by angle steel and high-strength bolt protective frame drawknot bolt outer with on former Prefabricated Concrete wallboard and be connected in every root bottom part connecting rod one end, the other end is connected to the vertical rod vertical with bottom connector rails by fastener, some bottom connector rails are composed in series foot guard railing by steel pipe, and some vertical rods are composed in series outer guard rail by steel pipe.
Improving further, between bottom connector rails and angle steel, full weld connects.
Angle between brace and horizontal plane is too little, can affect the weight capacity of safety net, and the scope of the too big then safety net protection of angle is too small, considers mechanical property and practicality, it is recommended that brace and horizontal plane angle are 30-60 °.
This utility model has the beneficial effects that: utilizes outer protective frame drawknot bolt on former Prefabricated Concrete wallboard to box out the erection method of design safety plain net, improves the safety coefficient of high-building construction.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is bottom connector rails and former Prefabricated Concrete wallboard connection diagram.
Detailed description of the invention
This utility model structure is as shown in Figure 1, including upper guardrail, lower guardrail and brace 1, described upper guardrail and lower guardrail are boxed out by angle steel 2 and high-strength bolt 3 protective frame drawknot bolt outer with on former Prefabricated Concrete wallboard and are connected, it is connected with lower guardrail bottom described brace 1, between brace 1 top and upper guardrail, has drawn safety net 4.
Described upper guardrail and lower guardrail all include the bottom connector rails 5 of some horizontal directions column distribution, boxed out by angle steel 2 and high-strength bolt 3 protective frame drawknot bolt outer with on former Prefabricated Concrete wallboard and be connected in every root bottom part connecting rod 5 one end, the other end is connected to the vertical rod 6 vertical with bottom connector rails 5 by fastener, some bottom connector rails 5 are composed in series foot guard railing by steel pipe 7, and some vertical rods 6 are composed in series outer guard rail by steel pipe 7.
Fig. 2 is bottom connector rails 5 and former Prefabricated Concrete wallboard connection diagram, and between bottom connector rails 5 and angle steel 2, full weld connects, and angle steel 2 is boxed out by high-strength bolt 3 protective frame drawknot bolt outer with on former Prefabricated Concrete wallboard and is connected.
Angle between brace 1 and horizontal plane is too little, can affect the weight capacity of safety net, and the scope of the too big then safety net protection of angle is too small, considers mechanical property and practicality, it is recommended that brace 1 and horizontal plane angle are 30-60 °.
A kind of specifically used parameter of each parts is as follows:
Brace 1: caliber is φ 48, length is 4500mm;
Angle steel 2:L90 × 140 × 8mm, long gambling is 150mm;
High-strength bolt 3: select M27 high-strength bolt.
Safety net 4: select high strength yarn P-3 × 6 safety net (bilayer);
Bottom connector rails 5, vertical rod 6 and all the other series connection steel pipe 7 calibers all select φ 48.
The concrete application approach of this utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model principle; can also making some improvement, these improvement also should be regarded as protection domain of the present utility model.
