Description

Technical Field

[0001] The utility model is applicable to the technical field of construction engineering, and particularly relates to an environmentally friendly noise reduction device for construction engineering management. Background Art

[0002] At present, when construction is carried out on a large area, in order to avoid excessive influence of noise from the construction site on the daily life quality of residents in surrounding living places, a large number of noise reduction and sound insulation panels are used to surround the outside of the construction site.

[0003] However, nowadays, when building noise reduction and sound insulation boards around the construction site, in order to improve the installation stability of the sound insulation boards, corresponding support rods are often tilted at both ends of the sides to provide installation support from the side of the sound insulation board. When the support rods are tilted for installation, not only do construction workers need to manually adjust their inclination before using multiple sets of bolts to tighten and reinforce them, which is time-consuming and labor-intensive, but also for a large number of support rods, it is impossible to ensure that their overall inclination is the same, which leads to insufficient lateral support force provided by different support rods to the sound insulation board, affecting the stability of the sound insulation board when in use. Therefore, we propose an environmentally friendly noise reduction device for construction engineering management. Utility Model Content

[0004] The main purpose of the utility model is to provide an environmentally friendly noise reduction device for construction engineering management, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A construction engineering management environmental noise reduction device, wherein noise reduction blocks are fixedly installed on the side of the plate body, and the number of noise reduction blocks is several groups, and connecting plates are fixedly installed on both ends of the side of the plate body away from the noise reduction blocks;

[0007] The side surface of each connecting plate is hinged with a support plate via a rotating shaft, and both ends of the bottom of the plate body away from the noise reduction block are hinged with a supporting plate via a rotating shaft;

[0008] A rotating rod is fixedly installed at the middle end of the top of each abutment plate, a fixed block is fixedly sleeved on the middle end surface of each rotating rod, a limiting block is fixedly installed on the side of each fixed block close to the support plate, and the limiting block is slidably inserted into the inside of the support plate, and an anti-slip friction pad is fixedly bonded to the bottom surface of each support plate.

[0009] By adopting the above technical solution, through the mutual cooperation of the abutment plate and the support plate, the operator only needs to press down the abutment plate to abut the support plate and make it tilt from the side of the plate body, thereby reducing the number of operating steps required for the operator to install it and adjust the inclination, and facilitating unified control of the support inclination of the support plate, thereby improving the support stability of the plate body.

[0010] As an optional solution of the technical solution of the present application, a limiting groove is provided at the middle end of one side of each support plate close to the connecting plate, and the limiting block is slidably inserted into the limiting groove.

[0011] By adopting the above technical solution, the guiding sliding action of the limiting groove on the limiting block ensures the rationality of the transmission of the supporting plate by the rotation of the abutting plate.

[0012] As an optional solution of the technical solution of the present application, fixing screw holes are vertically opened on both sides of the top of the plate body, and a fixing bolt is vertically screwed in each of the fixing screw holes through a thread.

[0013] By adopting the above technical solution, the limit rod is prevented from moving out of any insertion slot through the screwing action of the fixing bolt and the fixing screw hole.

[0014] As an optional solution to the technical solution of the present application, plug-in grooves are horizontally opened inside both ends of the side edges of the plate body, and limit rods are laterally fixedly installed at both ends of the other side of the plate body, and the limit rods and the plug-in grooves are at the same horizontal position, and an installation groove is opened inside the middle end of each limit rod.

[0015] By adopting the above technical solution, the two sets of plates can be stably assembled and installed for use through the structural effects of the plug-in slots and the limiting rods.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is an environmentally friendly noise reduction device for construction engineering management, wherein a rotatable support plate is arranged at both ends of the rear side of the plate body, and a rotatable abutment plate is arranged between the support plate and the plate body. When the support plate needs to be rotated to make it tilted at the rear side of the plate body to support it, the operator only needs to press down the abutment plate, thereby making the abutment plate rotate with the hinge point with the side edge of the plate body as the center of the circle, thereby driving the fixed block and the limit block to slide synchronously along the side edge of the support plate until the support plate is rotated from a vertical state to a horizontal state. The support plate can then be abutted to make it tilt from the side of the plate body, reducing the number of operating steps required for the operator to install and adjust the inclination, and facilitating unified control of the support inclination of the support plate, thereby improving the support stability of the plate body.

[0018] 2. The technical solution of the present application is an environmentally friendly noise reduction device for construction engineering management. By respectively arranging limit rods and plug-in slots on both sides of the plate body, when assembling two adjacent groups of plate bodies, it is only necessary to push the plate body to move the limit rod into the plug-in slot, and then vertically twist the fixing bolt to make it pass through the installation slot, and then the limit rod can be fixed and limited. While ensuring the stability of the plate body assembly, the labor consumption required for the plate body assembly can be simplified. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in FIG. 2 , a limiting groove 26 is provided at the middle end of one side of each support plate 21 close to the connecting plate 2 , and the limiting block 25 is slidably inserted into the limiting groove 26 .
