Description

TECHNICAL FIELD

[0001] The present application relates to the field of building walls, in particular, relates to a building wall structure with sound insulation and noise reduction function. BACKGROUND

[0002] The sound insulation wall is mainly used for sound insulation and noise reduction of highways, elevated composite roads and other noise sources, which is a wall structure set beside the railway and highway to reduce the impact of driving noise on nearby residents, and is also called a sound barrier; The sound insulation wall usually needs to be assembled during use, in order to facilitate assembly, the sound insulation wall is usually set as a combined structure, so as to ensure the functionality of the sound insulation wall.

[0003] In order to ensure the sound insulation and noise reduction effect, the sound insulation wall usually adopts a multi-layer structure, which makes the wall thickness larger, and is not convenient for transportation and installation, so the multi-layer wall is usually installed in sequence, but in the actual construction process, the multi-layer wall installed in sequence will cause error accumulation, and the outermost wall is prone to unevenness.

[0004] In order to ensure the flatness of the outer wall, the existing method is to install by inserting, but in order to ensure the firmness after inserting, the size redundancy of the inserted part is small, which leads to the need to align repeatedly before inserting, which is not convenient for construction, and if the size redundancy is increased, it will also cause the problem of unstable installation and inaccurate positioning.

[0005] Therefore, a building wall structure with sound insulation and noise reduction function is needed to solve the above problems. CONTENT OF THE UTILITY MODEL

The content part of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] To solve the technical problems mentioned in the background section, some embodiments of the present application provide a building wall structure with sound insulation and noise reduction function, comprising: a wall block, the wall block comprising a first wallboard, a second wallboard and a third wallboard, the first wallboard and the third wallboard are arranged on both sides of the second wallboard, the first wallboard and the second wallboard and the third wallboard are arranged and installed in sequence, the first wallboard and the second wallboard have a sound insulation space, and the second wallboard and the third wallboard also have a sound insulation space; a plug-in structure is arranged on the first wallboard, the second wallboard and the third wallboard, and is used for installing the first wallboard, the second wallboard and the third wallboard; the plug-in structure comprises: a plug-in block fixedly arranged on the first wallboard and the second wallboard, the plug-in block and the first wallboard form a slot, and the plug-in block and the second wallboard form a slot; a connecting plate fixedly arranged on the second wallboard and the third wallboard, the connecting plate is used for being inserted into the slot; a support assembly arranged on the plug-in block is used for limiting the second wallboard and the third wallboard; the support assembly comprises: a support block slidingly arranged on the plug-in block; an abutting block used for supporting the connecting plate; a hinged rod used for driving the abutting block to move and abut against the connecting plate; the abutting block is in contact with and closely attached to the connecting plate, and supports the connecting plate; wherein the arrangement direction of the first wallboard, the second wallboard and the third wallboard is set as the front-back direction, the insertion direction of the connecting plate inserted into the slot is the vertical direction, and the left-right direction perpendicular to the front-back direction and the vertical direction.

[0008] By arranging the connecting plate and the slot, the size of the slot is greater than that of the connecting plate, which facilitates the insertion of the connecting plate into the slot, thereby installing the first wallboard, the second wallboard and the third wallboard. By arranging the support block and the hinged rod, when the connecting plate is vertically inserted into the slot, the hinged rod is moved by pushing the support block, and then the abutting block abuts against the connecting plate to support the front-back direction of the connecting plate, thereby ensuring the stability of the connecting plate and the firm installation of the first wallboard, the second wallboard and the third wallboard.

[0009] Further, the support assembly further comprises: a support groove opened on the plug-in block, the support groove extends along the insertion direction of the connecting plate, the support block is slidingly arranged in the support groove, a screw rod is arranged on the support block, a shaft sleeve is arranged on the screw rod, the shaft sleeve is threadedly connected with the screw rod, one end of the shaft sleeve penetrates out of the support groove and is used for abutting against the connecting plate.

[0010] By arranging the screw rod and the shaft sleeve, when the shaft sleeve is rotated, the shaft sleeve moves relative to the screw rod, thereby adjusting the overall length of the screw rod and the shaft sleeve, when the connecting plate contacts the shaft sleeve, the screw rod is moved, thereby moving the support block. When the overall length of the screw rod and the shaft sleeve is relatively long, the movement distance of the support block is also relatively long, at this time the abutting block can abut against the connecting plate.

[0011] Further, the articulated rod member comprises a first articulated rod hingedly connected to the lower end of the support block, and the first articulated rod is deflected about the hinged axis so that the other end of the first articulated rod is shifted in the front-back direction.

[0012] Further, the articulated rod member further comprises a second articulated rod hingedly connected to the bottom wall of the support groove, and the second articulated rod is deflected about the hinged axis so that one end of the second articulated rod is shifted in the front-back direction, and the abutting block is hingedly connected to one end of the first articulated rod, and one end of the second articulated rod is also hingedly connected to the abutting block, and the deflection of the first articulated rod and the second articulated rod causes the abutting block to be shifted in the front-back direction and abut against the connecting plate, and the abutting block is further provided with a compression damping.

[0013] When the support block is pushed, the abutting block is moved towards the connecting plate under the cooperation of the first articulated rod and the second articulated rod, and when the abutting block abuts against the connecting plate, the compression damping is deformed under extrusion, so as to generate a pre-tightening force on the connecting plate.

[0014] Further, a sliding cavity is arranged in the support block, one end of the screw rod is inserted into the sliding cavity and fixedly connected with an extrusion block, the extrusion block is vertically slidably arranged in the sliding cavity, and a limiting block is also slidably arranged in the sliding cavity, and one end of the limiting block protrudes out of the sliding cavity for limiting the connecting plate.

[0015] Through the arrangement of the extrusion block and the limiting block, when one end of the limiting block protrudes out of the sliding cavity, the limiting block abuts against the side surface of the connecting plate in the left-right direction to position the connecting plate in the left-right direction.

[0016] Further, a tension spring is connected between the limiting block and the side wall of the sliding cavity, an inclined surface for pushing the limiting block is arranged on the extrusion block, an abutting surface parallel to the inclined surface is arranged on the limiting block, and a vertical surface is arranged on the extrusion block and the limiting block, and the inclined surface gradually moves away from the limiting block from top to bottom.

[0017] Through the arrangement of the tension spring, the limiting block is prevented from blocking the connecting plate when the connecting plate is not yet inserted into the insertion slot, and when the inclined surface on the extrusion block contacts the limiting block, the limiting block can be pushed to move and stretch the tension spring, and when the vertical surface on the extrusion block contacts the limiting block, the limiting block cannot move under the action of the tension spring.

[0018] Further, a buckle is arranged on the connecting plate, a clamping groove for embedding the buckle is formed in the first wall plate and the second wall plate, a buckle spring is arranged between the buckle and the connecting plate, and the two ends of the buckle spring are fixedly connected with the buckle and the connecting plate respectively.

[0019] When the connecting plate is completely inserted into the insertion slot, the buckle is embedded into the clamping groove to limit the connecting plate and the insertion block, the size of the clamping groove is larger than the size of the buckle, and when the buckle is embedded into the clamping groove, the vertical direction of the connecting plate is limited so that the connecting plate cannot be separated from the insertion slot.

[0020] Further, the connecting plate is provided with a folding part at the abutting position with the shaft sleeve, and a pushing protrusion of a pushing buckle is fixedly connected to the folding part, for pushing the buckle away from the clamping groove.

[0021] When the wall block needs to be disassembled, the folding part is opened, so that the folding part no longer abuts with the shaft sleeve, the shaft sleeve can be pulled, and the limiting block and the abutting block no longer fix the connecting plate, facilitating disassembly.

[0022] Further, the sound insulation space is filled with sound insulation cotton.

[0023] By arranging multiple adjacent sound insulation spaces, the noise can be weakened multiple times, ensuring the noise reduction effect.

[0042] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] Referring to Figures 1-4 A building wall structure with sound insulation and noise reduction function, comprising: wall blocks 100, plug-in blocks 101, slots 102, connecting plates 103, support blocks 104, abutting blocks 106. The wall block 100 is composed of a first wall plate 111, a second wall plate 112 and a third wall plate 113. The first wall plate 111 and the third wall plate 113 form the two side faces of the wall block 100. The second wall plate 112 is located between the first mounting plate and the third wall plate 113, and is used to form a sound insulation space 107 between the first mounting plate and the third wall plate 113. In one embodiment, multiple sound insulation spaces 107 can be formed in the wall block 100 by arranging multiple second wall plates 112 side by side, and the sound insulation spaces 107 are filled with sound insulation cotton.

[0044] The first wall plate 111 is fixedly connected with a plug-in block 101 on one side, and the plug-in block 101 has an "L" shaped structure in cross section. The plug-in block 101 and the first wall plate 111 form a slot 102 therebetween. The second wall plate 112 is fixedly provided with a connecting plate 103 on the side close to the first wall plate 111, and the connecting plate 103 is vertically inserted into the slot 102 to mount the first wall plate 111 and the second wall plate 112. Similarly, the second wall plate 112 is fixedly connected with a plug-in block 101 on the other side, and the third wall plate 113 is fixedly connected with a connecting plate 103 on the side close to the second wall plate 112. The second wall plate 112 and the third wall plate 113 are mounted by the plug-in block 101 and the connecting plate 103. Since the second wall plate 112 is fixedly connected with the plug-in block 101 and the connecting plate 103 on both sides, the second wall plate 112 can be mounted with each other.

[0045] The connecting plate 103 has an insertion part 108 embedded in the slot 102, a folding part 109 located at the upper end of the insertion part 108, and a connecting part 110 for connecting the insertion part 108. The connecting plate 103 can be fixed on the second wall plate 112 and the third wall plate 113 by the connecting part 110.

[0046] The connecting plate 103 is slidably connected with a buckle 114, and the buckle 114 is connected with the connecting plate 103 through a buckle spring, and the two ends of the buckle spring are fixedly connected with the buckle 114 and the connecting plate 103 respectively. The first wall plate 111 and the second wall plate 112 are provided with a clamping groove 116 for embedding the buckle 114.

[0047] The folding part 109 can be folded and opened, so that the folding part 109 has two states. In the first state, the folding part 109 is in a horizontal state and abuts against the insertion part 108 and the connecting part 110, and at this time the folding part 109 can be fixed through a bolt. In the second state, the folding plate is flipped relative to the insertion part 108, and the upper end of the connecting plate 103 is opened.

[0048] The folding part 109 is fixedly connected with a pushing protrusion 117 abutting against the buckle 114, and when the folding part 109 is folded relative to the insertion part 108, the pushing protrusion 117 pushes the buckle 114, so that the buckle 114 is separated from the clamping groove 116.

[0049] The insertion block 101 is provided with a vertically extending supporting groove 118, and the supporting groove 118 is slidably connected with a supporting block 104, and the supporting block 104 is hingedly connected with a first hinged rod 119, and one end of the first hinged rod 119 is hingedly connected with an abutting block 106, and the supporting groove 118 is also hingedly connected with a second hinged rod 120, and one end of the second hinged rod 120 is also hingedly connected with the abutting block 106. The first hinged rod 119 and the second hinged rod 120 are not parallel. When the supporting block 104 is pushed to move, the abutting block 106 moves towards the insertion part 108 of the connecting plate 103 under the action of the first hinged rod 119 and the second hinged rod 120, and pushes the connecting plate 103 to make the first wall plate, the second wall plate 112 and the third wall plate 113 close and support each other. The abutting block 106 is provided with a compression damping 121, and the abutting block 106 limits the front and back directions of the second wall plate 112.

[0050] A sliding groove 122 is formed in the support block 104, and the sliding groove 122 is open on one side. An extrusion block 123 is vertically and slidingly connected in the sliding groove 122, and a screw rod 124 is fixedly connected to the extrusion block 123 and protrudes out of the support block 104. A spring member 125 is arranged between the extrusion block 123 and the upper end wall of the sliding groove 122. A shaft sleeve 126 is sleeved on the screw rod 124, and the shaft sleeve 126 is threadedly connected with the screw rod 124. The shaft sleeve 126 penetrates through the plug-in block 101 and is located at the upper side of the plug-in block 101. When the connecting plate 103 is inserted into the plug-in groove 102, the folded portion 109 will contact the shaft sleeve 126 and press the shaft sleeve 126. A limiting block 105 is horizontally and slidingly arranged in the sliding groove 122, and one end of the limiting block 105 protrudes out of the sliding groove 122 and is used for abutting against the connecting portion 110 of the connecting plate 103. A compression damping 121 is arranged on the side, where the limiting block 105 and the connecting portion 110 abut against each other. The compression damping 121 can be a rubber block. The limiting block 105 limits the left-right direction of the second wall plate 112.

[0051] An inclined surface for pushing the limiting block 105 is arranged on the extrusion block 123, an abutting surface parallel to the inclined surface is arranged on the limiting block 105, vertical surfaces are arranged on the extrusion block 123 and the limiting block 105, and the inclined surface gradually moves away from the limiting block 105 from top to bottom. A tension spring 127 is connected between the limiting block 105 and the side wall of the sliding cavity.

[0052] Installation or use process:

[0053] 1. When the second wall plate 112 needs to be installed on the first wall plate 111, the insertion portion 108 of the mounting plate is vertically inserted into the plug-in groove 102, and when the folded portion 109 abuts against the shaft sleeve 126, the shaft sleeve 126 is pressed, the extrusion block 123 is pushed through the screw rod 124, the support block 104 is first driven to move under the action of the spring member 125, the abutting block 106 is driven to move towards the insertion portion 108 under the action of the first hinge rod 119 and the second hinge rod 120, and the insertion portion 108 is abutted and supported, so as to support the second wall plate 112 in the front-back direction and drive the second wall plate 112 to be close to the first wall plate 111, thereby ensuring firm installation.

[0054] 2. When the abutting block 106 contacts the insertion portion 108, the support block 104 no longer moves, at this time, the extrusion block 123 continues to move, thereby stretching the spring member 125, and under the action of the inclined surface on the extrusion block 123, the limiting block 105 is driven to move, so that the limiting block 105 protrudes and abuts against the connecting portion 110 of the connecting plate 103, thereby supporting the second wall plate 112 in the left-right direction and ensuring that the second wall plate 112 is installed opposite to the first wall plate 111.

[0055] 3. When the bushing 126 is pressed down further, the buckle 114 is positioned in the slot 116 and embedded within it. Simultaneously, the pressing block 123 abuts against the vertical surface of the limiting block 105, limiting the position of the limiting block 105. At the same time, the compression damper 121 deforms, supporting the second wall panel 112 and generating a preload to prevent wobbling. When the preload needs adjustment, the bushing 126 is rotated to adjust the overall length of the bushing 126 and the screw 124, thereby adjusting the movement distance of the support block 104. A longer movement distance results in greater deformation of the compression damper 121 and a greater preload. The same principle applies when installing the third wall panel 113.

[0056] 4. When it is necessary to disassemble the second wall panel 112, by opening the folding part 109, the buckle 114 is disengaged from the slot 116 under the action of pushing the protrusion 117. At this time, the bushing 126 can be pulled so that the abutment block 106 and the limiting block 105 no longer support the second wall panel 112, which facilitates the disassembly of the second wall panel 112.

[0057] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
