Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a structural connector for composite bricks. Background Technology

[0002] In the modern construction field driven by the "dual carbon" goals, the clustering development of high-rise buildings and the improvement of building energy efficiency standards present dual technical challenges. On the one hand, the proportion of buildings over 100 meters tall is increasing year by year, and the self-weight of traditional solid brick walls has become the main load source in structural design. When the building height exceeds 50 meters, the contribution rate of wall self-weight to the foundation load exceeds 35%, thus the self-weight of the walls becomes the main factor limiting building height. On the other hand, the "General Code for Building Energy Conservation and Renewable Energy Utilization" requires that the average design energy consumption level of residential buildings and public buildings should be reduced by 30% and 20% respectively based on the energy-saving design standards implemented in 2016, and wall insulation is an important part of building energy conservation. The high thermal conductivity of traditional solid bricks leads to a high heat transfer coefficient in walls built with traditional solid bricks, making it easy for heat to be lost through the walls, resulting in poor wall insulation and thus restricting the implementation of building energy efficiency standards. Therefore, there is an urgent need to design a type of brick with low density and low thermal conductivity to provide an integrated solution for weight reduction and wall insulation in high-rise buildings.

[0003] In the prior art, for example, Chinese utility model patent application number 200610135881.3 specifically discloses a foam plastic sandwich brick, which is composed of two concrete shells sandwiching a foam plastic core in the middle. The shells and the core are one of the following inlaid structures with rounded corners: dovetail groove shape, round pillar shape, or elliptical shape. By inserting a foam plastic core between two blocks, the density and thermal conductivity of the brick can be reduced. However, this patent directly inserts the foam plastic core between two blocks. When the foam plastic sandwich brick is subjected to external force, the pressure is applied to both the blocks and the foam plastic core simultaneously. Due to the weak compressive strength of the foam plastic core, it is prone to deformation under the same external force, thus making the entire brick structure unstable and reducing the load-bearing capacity of the foam plastic sandwich brick. Summary of the Invention

[0004] In view of this, the present invention provides a structural connector for a modular brick to solve the technical problem of low load-bearing capacity of foam plastic sandwich bricks.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A structural connector for composite bricks, used in conjunction with the building blocks of composite bricks, includes a fixing member and plugs disposed at the left and right ends of the fixing member. The upper part of the fixing member is a protrusion and the lower part is a recess. The structure of the plugs corresponds to the structure of the mounting groove of the building block of the composite bricks, so that the plugs at the left and right ends are respectively inserted into the mounting grooves of the two building blocks to connect the two building blocks.

[0006] Preferably, the connector has a connecting portion extending to the left and right sides from one end near the fixing member, and the side of the connecting portion facing the mounting groove of the masonry block has barbs to fix the structural connector.

[0007] Preferably, the protrusion of the fixing member has a first strip-shaped hole, the length direction of the first strip-shaped hole being perpendicular to the length direction of the plug, so as to facilitate the insertion and removal of the structural connector.

[0008] Preferably, the fastener has a second strip-shaped hole in the middle, and the length direction of the second strip-shaped hole is perpendicular to the length direction of the first strip-shaped hole.

[0009] Preferably, the fastener has an I-shaped hole, and the upper part of the I-shaped hole is located on the protrusion.

[0010] Preferably, the head width of the connector is greater than the groove width of the mounting groove of the masonry block to prevent the connector from falling out of the groove.

[0011] Preferably, the cross-sectional shape of the head of the connector is any one of rectangle, circle, or trapezoid.

[0012] Preferably, the number of the fasteners is one, and the structural connector is in the shape of an "I".

[0013] Preferably, there are two fasteners, one end of which is connected to the same connector, and the other end of which is connected to different connectors, so that the connecting parts are V-shaped.

[0014] Preferably, the fixing member includes a first fixing member, a second fixing member, a third fixing member, and a fourth fixing member, and the connector includes a first connector, a second connector, a third connector, a fourth connector, and a fifth connector; one end of the first fixing member is connected to the first connector, and the other end of the first fixing member is connected to the second connector; one end of the second fixing member is connected to the second connector, and the other end of the second fixing member is connected to the third connector; one end of the third fixing member is connected to the third connector, and the other end of the third fixing member is connected to the fourth connector; one end of the fourth fixing member is connected to the fourth connector, and the other end of the fourth fixing member is connected to the fifth connector; wherein, the first connector, the third connector, and the fifth connector are inserted into the mounting groove of one of the masonry blocks; the second connector and the fourth connector are inserted into the mounting groove of another masonry block, so that the structural connector is "M" shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The structural connector of this utility model is a single unit, including a fixing component and plugs located at both ends of the fixing component. In use, the plugs at both ends of the structural connector are inserted into the mounting grooves of the two masonry blocks to connect them together. Compared to traditional sandwich bricks, where insulation and fireproofing material is directly filled between two masonry blocks, this utility model adds a structural connector, which can fix the two masonry blocks together. When subjected to external force, the structural connector can disperse the concentrated load, evenly transmitting the pressure to the masonry blocks on both sides, reducing the pressure peak of the structural connector and the insulation and fireproofing material, thereby improving the overall load-bearing capacity of the composite brickwork.

Detailed Implementation

[0024] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please also refer to Figure 1 and Figure 2 A structural connector 10 for composite brick blocks, used in conjunction with the masonry blocks 20 of the composite brick blocks, includes a fixing member 110 and plugs 120 disposed at the left and right ends of the fixing member. The upper part of the fixing member 110 is a protrusion 111 and the lower part is a recess 112. The structure of the plugs 120 corresponds to the structure of the mounting groove 210 of the masonry blocks 20 of the composite brick blocks, so that the plugs 120 at the left and right ends are respectively inserted into the mounting grooves 210 of the two masonry blocks 20 to connect the two masonry blocks 20.

[0026] The structural connector 10 of this utility model is an integral unit, including a fixing member 110 and plugs 120 disposed at both ends of the fixing member. In use, the plugs 120 at both ends of the structural connector 10 are respectively inserted into the mounting grooves 210 of the two masonry blocks 20 to connect the two masonry blocks 20 together. Compared with traditional sandwich bricks, which directly fill the space between two masonry blocks with heat insulation and fireproofing material, this utility model adds the structural connector 10, which can fix the two masonry blocks together. Since the masonry blocks are the main load-bearing components of the composite bricks, when subjected to external forces, the structural connector 10 can disperse the concentrated load and evenly transmit the pressure to the masonry blocks 20, so that the pressure is mainly applied to the load-bearing components, reducing the pressure peak of the structural connector 10 and the heat insulation and fireproofing material, thereby improving the overall load-bearing capacity of the composite bricks. In addition, the structural connector 10 is set in the gap between the two masonry blocks, which can support and fix the filled thermal insulation and fireproof material, preventing the thermal insulation and fireproof material from falling off between the two masonry blocks, thereby further enhancing the stability of the composite bricks.

[0027] In some embodiments, the distance between two building blocks 20 can be changed by altering the length of the connecting member 10, thereby reducing the density of the composite bricks of this invention within the same volume. The connecting member 10 can be made of engineering plastics or metal components, and this is not limited to any particular material.

[0028] Further, please see Figure 1 The connector 120 has a connecting portion 121 extending to the left and right sides from one end near the fixing member 110. The side of the connecting portion 121 facing the mounting groove of the masonry block has barbs 122 to secure the structural connector 10. Since the connector 120 is inserted into the mounting groove 210 from above, it is prone to detaching from below. Therefore, this invention provides barbs 122 on the side of the connecting portion 121 facing the mounting groove 210. The barbs 122 effectively hold the inner end face of the masonry block 20, thereby strengthening the connection between the connecting portion 121 of the connector 120 and the inner end face of the masonry block 20, and preventing the connector 120 from detaching from below the mounting groove 210. The connecting part 121 has barbs 122 on its entire surface facing the mounting groove of the masonry block, thereby increasing the contact area between the barbs 122 and the inner end face of the masonry block 20 and improving the anti-detachment effect of the barbs 122. The barbs 122 can be single-pointed single-sided barbs, double-pointed single-sided barbs, etc., and are not limited here. In some embodiments, the connecting part 221 is engaged with the inner end face of the masonry block 10, which can restrict the back-and-forth movement of the connector 220 in the mounting groove 110, thereby fixing the structural connector 20.

[0029] Further, please see Figure 1 The protrusion 111 of the fastener 110 has a first strip-shaped hole 113, the length direction of which is perpendicular to the length direction of the connector 120, to facilitate the insertion and removal of the structural connector 10. The first strip-shaped hole 113 on the protrusion 111 of the fastener 110 serves as a handle for the structural connector 10. When connecting two masonry blocks 20, fingers pass through the first strip-shaped hole 113 to grasp the upper part of the fastener 110, and then the connectors 120 at both ends of the structural connector 10 are placed simultaneously on the mounting groove 210 of each masonry block. By grasping the first strip-shaped hole 113, a downward force is applied to the structural connector 10, causing the connector 120 to insert into the mounting groove 210, thereby improving the ease of installation of the structural connector 10. Meanwhile, after the first strip hole 113 is opened, when the thermal insulation and fireproof material is filled between the two masonry blocks 20, the thermal insulation and fireproof material can pass through the first strip hole 113 and connect into a whole, thereby increasing the support for the thermal insulation and fireproof material and preventing the thermal insulation and fireproof material from falling off.

[0030] Further, please see Figure 1The fastener 110 has a second strip-shaped hole 114 in its center, and the length direction of the second strip-shaped hole 114 is perpendicular to the length direction of the first strip-shaped hole 113. When thermal insulation and fireproofing material is filled between the two masonry blocks, the thermal insulation and fireproofing material will also pass through the second strip-shaped hole 114, so that the filled thermal insulation and fireproofing material forms a whole, rather than being divided into multiple parts by the structural connector 10. This avoids the risk of the thermal insulation and fireproofing material falling off when cut into multiple parts by the structural connector. At the same time, the structural connector 10 fixes and supports the entire thermal insulation and fireproofing material, further preventing the thermal insulation and fireproofing material from falling off, thereby improving the stability of the composite bricks.

[0031] In some implementations, please refer to Figure 3 In this invention, an I-shaped hole is provided in the fixing member 110. For the modular bricks mentioned in this invention, there are two heat transfer paths. One is "building block - thermal insulation and fireproof material - building block brick," and the other is "building block - connector - fixing member - connector - building block." With the I-shaped hole provided in the fixing member 110, the thermal insulation and fireproof material can fill the inside of the I-shaped hole, thus blocking the direct connection between the two connectors and changing the heat transfer path to "building block - connector - fixing member - thermal insulation and fireproof material - fixing member - connector - building block." The structural connector 10 is made of metal or engineering plastic. Since the thermal conductivity of the insulating and fireproof material is lower than that of metal and engineering plastic, when heat is transferred from the connector and fastener to the insulating and fireproof material, the material blocks heat conduction, thereby reducing the thermal bridge effect between the masonry block 20 and the structural connector 10. This further reduces the thermal conductivity of the entire composite brickwork and improves its insulation performance. The upper hole of the I-shaped hole is located at the protrusion 111 of the fastener 110 and can be used as a handle for the fastener 110.

[0032] In one embodiment, the shape of the connector 120 can be exactly the same as the shape of the mounting groove 210, so that after the connector 120 is inserted into the mounting groove 210, the connector 120 and the mounting groove 210 fit together completely, improving the stability of the connection between the masonry block 20 and the structural connector 10. In another embodiment, the shape of the cross-section of the head of the connector 120 can also be different from the shape of the cross-section of the mounting groove 210. The shape of the cross-section of the head of the connector 120 can be circular, rectangular, trapezoidal, etc., but the width of the head of the connector 120 must be greater than the width of the groove opening of the mounting groove 210 of the masonry block 20 to ensure that the connector 120 will not be pulled out or fall off from the groove opening of the mounting groove 210.

[0033] Furthermore, the number of fasteners 110 is one, and the connecting member 10 is shaped like the letter "I". For details, please refer to... Figure 1Each connector 120 has two connection points at its tail, where the opening at the tail of the connector connects to the connecting part 121. When the fixing member 110 is connected to the connector 120, the two connectors 120 are positioned opposite each other, and the two ends of the fixing member 110 are connected to the opposite connection points of the two connectors, making the fixing member 110 perpendicular to the connector 120, thus making the entire structural connector 10 in a straight line shape. When assembling this structural connector 10 with the masonry block 20, the connectors 120 at both ends of the fixing member 110 are inserted into the mounting grooves 210 of the two masonry blocks 20 respectively, with the fixing member 110 perpendicular to the masonry block 20, and the structural connector 10 in a straight line shape, thereby reducing the cost of the structural connector 10 and thus reducing the cost of the composite bricks. In some embodiments, such as Figure 2 As shown, in order to make the connection between the two masonry blocks more stable, two "I"-shaped structural connectors 10 can also be used to connect the two masonry blocks 20.

[0034] In some embodiments, there is only one fastener 110, but the two connectors 120 are staggered, so that the fastener 110 is connected to the two connectors 120 at a certain angle. When the fastener with this structure is assembled with the masonry block 20, the fastener 110 is not perpendicular to the masonry block 20, but at a certain angle. Therefore, when the composite brick block is subjected to external force, the inclined fastener 110 can better distribute the pressure and enhance the overall stability.

[0035] Furthermore, please also refer to Figure 4 and Figure 5 There are two fasteners 110. One end of each fastener 110 is connected to the same connector 120, and the other ends are connected to different connectors 120, making the structural connector 10 "V" shaped. Specifically, the two fasteners 110 connected to the same connector 120 can be connected to two different connection points of the same connector 120. The connectors 120 connected to the other ends of the two fasteners 110 are staggered with the same connector 120, thus forming a triangular structure between the two fasteners 110 and the masonry blocks 20 between them. When the composite bricks are subjected to external forces, the triangular structure can effectively distribute the load, evenly distributing the pressure on each fastener and masonry block. It can effectively resist lateral and longitudinal forces, improve the connection strength of the structural connector 10, and thus improve the stability, load-bearing capacity, and seismic resistance of the composite bricks. Additionally, please refer to... Figure 4 and Figure 5The connecting portion 121 on the connector 120 contacts the inner end face of the masonry block 20. When the interior of the composite brick is subjected to temperature changes, for example, when the masonry blocks 20 on both sides expand due to heat, the connecting portion 121, subjected to the force applied by the masonry blocks 20, will compress the heat-insulating and fireproof material and generate a force inward into the composite brick. The forces generated by the masonry blocks on both sides simultaneously inward into the composite brick will cancel each other out, thereby balancing the force inside the composite brick, reducing the deformation caused by thermal expansion and contraction inside the composite brick, and reducing the impact of thermal expansion and contraction on the composite brick.

[0036] Furthermore, please also refer to Figure 6 and Figure 7 The fastener 110 includes a first fastener 115, a second fastener 116, a third fastener 117, and a fourth fastener 118. The connector 120 includes a first connector 123, a second connector 124, a third connector 125, a fourth connector 126, and a fifth connector 127. One end of the first fastener 115 is connected to the first connector 123, and the other end of the first fastener 115 is connected to the second connector 124. One end of the second fastener 116 is connected to the second connector 124, and the other end of the second fastener 116 is connected to the third connector 125. The connection is as follows: one end of the third fastener 117 is connected to the third connector 125, the other end of the third fastener 117 is connected to the fourth connector 126, one end of the fourth fastener 118 is connected to the fourth connector 126, and the other end of the fourth fastener 118 is connected to the fifth connector 127; wherein, the first connector 123, the third connector 125, and the fifth connector 127 are inserted into the mounting groove of one of the masonry blocks 20; the second connector 124 and the fourth connector 126 are inserted into the mounting groove of the other masonry block 20, so that the structural connector 10 is "M" shaped. By setting the M-shaped connector, the first fastener 115, the second fastener 116, the third fastener 117, and the fourth fastener 118 form multiple triangular structures with the inner end face of the masonry block 20, further improving the connection strength of the structural connector 10, as well as improving the stability, load-bearing capacity, and seismic resistance of the composite bricks. Figure 1 , Figure 3 , Figure 4 and Figure 6 The structure of the structural connector shown is only an example. Depending on the length of the masonry block and the number of mounting slots, the structural connector 10 can also be a diagonal type, a double M type, etc. The specific shape of the structural connector 10 is not limited here.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
