Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and more particularly to a noise-reducing construction site building structure and a construction method thereof. Background Art

[0002] During construction, construction site buildings serve as temporary offices, rest areas, and storage spaces for tools and materials. The noise generated by these buildings is a growing concern. Traditional construction sites typically utilize simple steel structures or pre-painted steel panels, resulting in relatively simple structures and poor sound insulation. Various noises generated during construction, such as mechanical operation and material handling, can easily be transmitted through the walls and roofs of the buildings, causing significant disruption to the lives and work of surrounding residents and potentially violating noise emission restrictions in relevant environmental regulations.

[0003] Currently, common window installation methods for construction site buildings, such as expansion bolt mounting, nail gun installation, and pre-installed components, present numerous challenges. During construction, these methods can create gaps between the window and the wall, resulting in poor sealing. External noise can easily enter the building through these gaps. The vibrations generated by this external noise can cause the window to resonate, further amplifying the noise. This reduces the comfort and safety of the construction site building, impacting the work and rest of occupants. Therefore, we propose a noise-reducing construction site building structure and its construction method. Summary of the Invention

[0004] The purpose of the present invention is to provide a noise reduction construction site building structure and a construction method thereof, so as to solve the technical problem that the current window fixing installation method has gaps, easily generates resonance, and amplifies the noise effect.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a noise-reducing construction site building structure and a construction method thereof, comprising a construction site building body composed of a plurality of room panels, a window being constructed on a panel wall of a room panel on one side of the construction site building body, a window body being installed inside the window, an embedded groove communicating with the four sides of the window being opened on the side of the room panel of the construction site building body, a connecting block being reserved between two adjacent embedded grooves, and a connecting plate being fixedly provided on the outer frame of the window body with a connecting plate in contact with the side of the embedded groove; The side of the connecting plate that is in contact with the embedded groove is provided with a connecting groove, and the side of the embedded groove is fixedly provided with a connecting piece that is combined with the connecting groove; A sealing frame for fixing the position of the connecting plate is fixedly connected between the four connecting blocks. A sound insulation strip that fits the side of the connecting plate is fixedly provided on the side of each sealing frame facing the connecting plate, and the internal structure of the sound insulation strip is provided with honeycomb holes.

[0006] The present invention provides a sound insulation strip with honeycomb holes. The honeycomb structure can effectively absorb and disperse noise, reduce the sound propagation efficiency, and significantly improve the sound insulation effect of the construction site room. At the same time, the cooperation between the connecting parts and the connecting grooves and the positioning grooves enables the window body to be tightly connected to the construction site room body, reducing the noise introduced by gaps, effectively preventing external noise from entering the room through the gaps, and greatly improving the comfort and safety of the construction site room.

[0007] Preferably, the end facing surfaces of the connecting groove are extended to form a locking groove, and the side shape of the locking groove is arc-shaped.

[0008] Preferably, the connecting member includes two bendable elastic plates, the opposite ends of the two elastic plates are integrally formed with a locking strip combined with the locking groove, and a V-shaped spring piece for support is fixedly connected between the facing surfaces of the two elastic plates.

[0009] Preferably, a plurality of triangular sealing grooves are provided on the side of the connecting plate that is in contact with the embedded groove, and a sealing strip combined with the sealing groove is fixedly provided on the side of the embedded groove, and the sealing strip is made of a flexible material.

[0010] Preferably, a positioning hole is provided at the center of each of the connecting blocks, and a threaded hole communicating with the positioning hole is provided inside the connecting block.

[0011] Preferably, a positioning tube that is plugged into the positioning hole is fixedly provided at each corner of the sealing frame, and the inner wall of the positioning tube is constructed with an internal thread that cooperates with the threaded hole. A fixing bolt that passes through the wall of the sealing frame is installed inside the positioning tube, and the end of the fixing bolt is threadedly connected to the threaded hole.

[0012] Preferably, the side of the sound insulation strip close to the connecting plate is provided with an arc-shaped positioning groove, the center of the positioning groove is constructed with a raised elastic ridge, the other side of the embedded groove is fixed with a positioning strip combined with the positioning groove, and the center of the end of the positioning strip is constructed with a resistance groove that is engaged with the elastic ridge.

[0013] Preferably, a groove for hiding the end position of the fixing bolt is opened on the side of the corner of the sealing frame, and the interior of the groove is sealed with a sealing block that fits with the end of the fixing bolt.

[0014] Preferably, an annular groove is formed on the inner wall of the groove, and two elastically retractable positioning buckles are fixedly provided on the outer wall of the blocking block, and the positioning buckles are snap-connected to the annular groove.

[0015] A construction method for a noise reduction construction site building structure comprises the following steps: S1. Construction of construction site: clean up the construction site, remove obstacles, ensure the site is level, debug and maintain construction equipment, organize and assemble accessories, and build the main body of the construction site; S2, window installation steps; S2.1. Window Installation: Align the connecting plate of the window's outer frame with the embedded groove on the side of the main building's panel. Since the connecting groove on the connecting plate fits in with the connector on the side of the embedded groove, the two elastic plates in the connector bend when squeezed. The retaining strips at the ends snap into the retaining grooves extending from the ends of the connecting grooves. The V-shaped spring clips also provide support, ensuring that the window is initially and firmly installed on the window. S2.2, Sealing strip and connecting plate combination: The triangular sealing groove on the side of the connecting plate is combined with the sealing strip on the side of the embedded groove. Since the sealing strip is made of flexible material, it can tightly fill the sealing groove; S2.3. Installation of the blocking frame: The installation position of the blocking frame is limited by the setting of the connecting block, and the positioning tube is inserted into the interior of the positioning hole so that the sound insulation strip and the connecting plate are closely connected. The embedded groove is filled with the sound insulation strip, and the sound insulation strip is deformed when it contacts the positioning strip under the extrusion force. When the positioning groove and the positioning strip are aligned, they can rebound and reset to combine, which initially limits the blocking frame. The combination of the elastic convex strip and the resistance groove can increase the displacement resistance and further strengthen the limiting strength. Then, the fixing bolt is rotated through the blocking frame into the interior of the positioning tube and connected to the threaded hole while continuing to rotate. In this way, the position of the blocking frame can be fixed, and the installation of the blocking frame is completed; S2.4. Installation of the blocking block: After the blocking block is installed in place with the fixing bolts, it can be inserted into the groove. Under the expansion and contraction characteristics of the blocking block itself, the positioning buckle can be moved to the annular groove position to achieve the clamping limit. The contact between the blocking block and the fixing bolts can limit the back movement of the fixing bolts, and also plays a sealing and protective role.

[0016] S3. Acceptance of the sound insulation and noise reduction effect of the window body: After the assembly is completed, the staff will enter the main body of the construction site and close the main body of the window to experience the sound insulation situation.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a sound insulation strip with honeycomb holes. The honeycomb structure can effectively absorb and disperse noise, reduce the sound transmission efficiency, and significantly improve the sound insulation effect of the construction site room. At the same time, the cooperation between the connecting parts and the connecting grooves and the positioning grooves makes the window body tightly connected to the construction site room body, reduces the noise introduced by the gaps, effectively prevents the external noise from entering the room through the gaps, and greatly improves the comfort and safety of the construction site room.

[0018] 2. The present invention also forms a multiple sealing structure by combining the sealing groove on the side of the connecting plate with the sealing strip on the side of the embedded groove, which effectively prevents the intrusion of external noise, dust and rainwater; in addition, the cooperation between the positioning groove and the positioning strip, the elastic convex strip and the resistance groove further enhances the tightness and sealing of the connection, ensuring the stability and comfort of the internal environment of the construction site.

[0019] 3. The present invention also uses the elastic plate and V-shaped spring clip in the connecting part to make the connection between the window body and the construction site house body have a certain elasticity and buffering capacity. Under the influence of vibration generated by external noise, it can effectively reduce the resonance phenomenon of the window and avoid the noise from being amplified; at the same time, the coordination of the positioning tube, fixing bolts and positioning holes, threaded holes, and the fixing effect of the blocking frame ensure the stability of the window installation and improve the overall safety of the construction site house.

[0020] 4. The structural design of the present invention facilitates the installation and disassembly of windows. Through the cooperation of positioning tubes, fixing bolts and other components, the installation of windows can be completed quickly and accurately. At the same time, the design of the blocking block and the positioning buckle not only hides the end of the fixing bolt, making the appearance more beautiful, but also facilitates the inspection and maintenance of the fixing bolt when necessary, reducing maintenance costs and difficulty.

Window Installation: Align the connecting plate 3 of the outer frame of the window body 2 with the embedded groove 102 on the side of the main body 1 of the construction site.
