Description

TECHNICAL FIELD

[0001] The utility model relates to building construction technical field especially relates to a kind of for upper and lower roof passageway. BACKGROUND

[0002] According to the need of building design, part of building roof is designed as planting roof, and there is no passageway or ladder for going up to the roof during construction stage;However, when carrying out roof construction, operating personnel need to go up to the roof to carry out construction operation.

[0003] In the building structure as shown in Figure 1 There is only one exposed ladder attached to the inclined steel column at the construction site giant screen theater, and there is no safety protection measure around, so there is a certain risk for personnel to go up and down the ladder. There is no passageway between the giant screen theater steel stairs and the roof opening. In order to facilitate subsequent construction, a passageway for going up to the roof needs to be set up on the steel stairs.

[0004] Therefore, in order to ensure the safety of personnel during construction, and to facilitate roof operation during subsequent construction, it is necessary to design a special passageway to ensure that personnel can safely and conveniently pass between the roof and the floor. The core technical problem of this requirement is how to provide a reliable and safe passageway under the restriction of existing building structure and construction conditions, to ensure the safety of operating personnel, and to meet the dual requirements of construction progress and safety standards. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a passageway for going up and down the roof to solve the technical problems of lack of safe passageway when going up and down the roof, risk of personnel falling, and low construction efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a passageway for going up and down the roof, which comprises a main body part arranged obliquely between the upper roof and the lower roof, and an auxiliary part arranged on the top of the upper roof floor. The main body part comprises at least three first support steel pipes arranged obliquely, the first support steel pipes are welded by steel bars at the corner of the step adjacent to the lower roof stairs, and the first support steel pipes are provided with supporting steel pipes fixedly connected with the first support steel pipes longitudinally and transversely. The upper part of the first support steel pipe is provided with a close-mesh safety net, and the adjacent supporting steel pipes are respectively located on both sides of the close-mesh safety net. Two first handrails are arranged on the left and right sides of the up-and-down passageway, and the outer side of the first handrail is provided with a close-mesh safety net. The auxiliary part comprises a second support steel pipe fixedly connected with the first support steel pipe and the first handrail, and a second handrail fixedly connected with the first handrail, and the outer side of the second handrail is provided with a close-mesh safety net.

This design can effectively support the passage structure and enhance the carrying capacity of the passage, thereby ensuring the safety of the construction personnel when passing through. Meanwhile, the application of the safety mesh prevents the personnel from falling during the passing process, further improving the safety.

[0008] The auxiliary part is arranged on the top of the upper roof floor and connected with the main body part, thereby increasing the stability and safety of the overall passage and enabling the passage to be firmly fixed on the upper roof floor, avoiding the sliding or displacement of the passage structure and improving the overall stability of the structure.

The arrangement of the horizontal steel pipe enables the handrails to form a stable horizontal support, thereby reducing the possible shaking of the handrails during use and increasing the safety and stability of the users when passing through.

[0015] Further, two H-shaped steels connected to the bottom of the upper roof floor are arranged, and the two H-shaped steels are distributed on the front and rear sides of the main body part. A reinforcing steel pipe is fixedly connected between the H-shaped steels, and the reinforcing steel pipe is fixedly connected with the first support steel pipe and the first handrail, respectively.

[0016] The two H-shaped steels are arranged at the bottom of the upper roof floor, and the reinforcing steel pipes are fixedly connected between the two H-shaped steels, so that the stability of the passing channel in the horizontal and vertical directions is enhanced.

[0017] The fixed connection of the reinforcing steel pipes with the first supporting steel pipes and the first handrail further enhances the overall rigidity and stability of the channel structure, and ensures that the channel structure can bear larger loads and dynamic impacts during construction.

[0018] Further, the fixed connection is achieved by means of fasteners.

[0019] The fastener connection provides a flexible and safe connection means, so that the connection between the components is more stable and convenient to disassemble and adjust.

[0020] Further, the inclination angle of the reinforcing steel head is consistent with the inclination angle of the main body.

[0021] The inclination angle of the reinforcing steel head is consistent with the inclination angle of the main body, so that the reinforcing steel head can closely fit the step corner during welding, and the welding firmness and the overall stability of the structure are improved.

[0022] The passing channel for the upper and lower roofs has the following advantages:

[0023] In the scheme, the main body and the auxiliary body jointly constitute the stable passing channel of the upper and lower roofs. The main body is provided with the first supporting steel pipe, the supporting steel pipe and the first handrail, so that the channel structure has sufficient load-bearing capacity and stability, and a safe inclined passing path is provided to prevent people from falling during passing. The auxiliary body is arranged on the top of the upper roof floor and is connected with the main body, so that the stability and safety of the overall channel are further enhanced, the structure is prevented from sliding or displacement, and the overall stability and anti-overturning capacity of the structure are improved.

[0024] The first handrail is arranged on the left and right sides of the passage as reliable gripping support to ensure the safety of the construction personnel when going up and down the passage. The outer side of the first handrail is provided with a dense mesh safety net to further improve the protection effect, prevent accidental lateral falling and enhance the overall safety performance. The second support steel pipe and the second handrail are cross-fixedly connected to form a stable net-shaped support structure together with the first support steel pipe and the first handrail, thereby increasing the rigidity and stability of the auxiliary part, effectively dispersing and transferring the load when stressed and avoiding structural instability. Meanwhile, the bottom of the vertical steel pipe is fixed to the upper roof floor to increase the overturning resistance and stability of the passage and prevent lateral movement or inclination in use. The transverse steel pipe arranged at the top of the first handrail further enhances the overall rigidity of the passage structure, forms a stable transverse support, reduces the shaking of the handrail and improves the safety and stability of the user when passing through. The combination of these designs effectively solves the safety hazards of personnel going up and down the roof during construction and improves the safety and efficiency of the construction process.
