As shown in fig. 1 to 5, the present utility model provides a masonry wall bracket including a bracket body 100, a bearing wall connection portion 200, and a masonry support portion 300. The bearing wall connection part 200 is used for fixing the masonry wall bracket on the bearing wall 10, specifically, the bearing wall connection part 200 is provided with a connection hole, for example, the masonry wall bracket can be fixed on an embedded groove (not shown) in the bearing wall 10 by using a T-shaped bolt, or other connection parts for fixing the masonry wall bracket in the bearing wall 10 by using a hexagonal bolt or the like, and the masonry wall bracket can be suitable for steel structure building, concrete structure building and the like by selecting the hexagonal bolt. The masonry support portion 300 is used for supporting the brick-laid exterior wall 20. Hereinafter, description will be made taking hexagonal bolting as an example.
The bracket main body 100 comprises a connecting portion 120, a masonry support portion 300 is fixedly connected with the bottom of the connecting portion 120 and horizontally arranged, one side of the connecting portion 120 is provided with a horizontal support rod 110 and an inclined support rod 130, the horizontal support rod 110 horizontally extends towards the direction away from the connecting portion, and the inclined support rod 130 is located above the horizontal support rod 110 and forms an included angle with the horizontal support rod 110. The included angle is preferably 30 ° -70 °, more preferably 35 °. The end of the inclined strut 130 remote from the connection portion is detachably connected to the load-bearing wall connection portion 200.
The masonry support portion 300 is a flat plate horizontally arranged, and the flat plate may be circular, trapezoidal, square, etc. When the masonry wall bracket is fixed to the load bearing wall 10, the bricks of the masonry outer wall 20 may be placed on the masonry support portion 300, so that the load of the masonry outer wall 20 is transferred into the load bearing wall 10 through the masonry wall bracket to ensure the stability of the masonry outer wall 20. The masonry support portion 300 and the connection portion 120 may be integrally formed or welded. The connecting mode of the components can be integrated or welded.
In order to avoid the damage to the bearing wall 10 caused by the horizontal strut 110 and the abrasion of the bearing wall 10 by the end of the horizontal strut 110, and to enable the masonry wall bracket to be suitable for the brick external wall 20 with uneven surface, the end of the horizontal strut 110 away from the connecting portion is provided with a propping adjusting portion 140. Illustratively, the abutment adjusting part 140 includes an adjusting nut 141 (e.g., an elongated nut, etc.) and an adjusting bolt 142 (e.g., a hexagonal bolt, etc.) which are threadedly coupled, wherein the adjusting nut 141 is fixedly coupled to the horizontal strut 110 and the central axis thereof is parallel to the longitudinal direction of the horizontal strut 110. The verticality of the masonry wall bracket can also be adjusted by screwing the adjustment bolt 142. The present utility model is not limited to the specific structure of the abutment adjusting part, and a person skilled in the art may use other components in the related art to realize the function of the abutment adjusting part, and may design the sizes of the adjusting nut 141 and the adjusting bolt 142 according to actual situations, and the present utility model is not limited thereto.
In order to make the masonry wall bracket more adaptable and mechanically strong, it is preferable that the masonry support portion 300 is located below the connection portion 120, the horizontal strut 110 and the adjustment nut 141, that is, the masonry support portion 300 is fixedly connected (e.g., welded or the like) to the connection portion 120, the horizontal strut 110 and the adjustment nut 141.
In the present utility model, the bracket body 100 composed of the connection part 120, the horizontal strut 110 and the inclined strut 130 is substantially right triangle, and a void space is provided between the horizontal strut 110 and the inclined strut 130. Preferably, the void space is right trapezoid, but the utility model is not limited thereto. The structure is obtained by defining boundary conditions by using a finite element method and taking a heat conduction value, a material utilization rate and the like as objective functions.
Through many experiments and mechanical analysis, it is found that when the masonry is placed on the masonry support portion 300, the force applied to the bracket main body 100 by the masonry support portion 300 is mainly divided into a pulling force which is inclined downward along the inclined strut 130 and a pressing force which is horizontally directed to the load bearing wall 10 along the horizontal strut 110. The bracket body of the present utility model, which does not adopt a substantially rectangular triangle-shaped flat plate structure (i.e., the horizontal strut 110 and the inclined strut 130 are not connected together without a void space therebetween), is because when the bracket body of the flat plate structure is adopted, the middle portion (the portion substantially identical to the void space portion in the present embodiment) of the bracket body of the flat plate structure is not used to bear load, and because it connects the horizontal strut and the inclined strut, the stress direction of the horizontal strut and the inclined strut is different, the internal stress generated in the middle portion conversely reduces the strength of the bracket body, so that the load that it can bear is reduced.
The strength of the masonry wall brackets of the present utility model was tested by a specific test as follows. Two masonry wall brackets were made of the same material (e.g., Q235 steel) and differ only in that one of the two is identical in structure to that shown in fig. 1, i.e., a void space was provided between the horizontal strut and the diagonal strut, and the other adopts a right triangle-shaped flat plate-like structure as the bracket body, i.e., no void space was provided between the horizontal strut and the diagonal strut. Specifically, the overhanging lengths of the masonry wall brackets (the total length of the masonry wall brackets in the horizontal direction shown in fig. 4) are all 130mm, the vertical distances between the masonry support portions and the connecting holes on the bearing wall connecting portions are all 200mm, the masonry support portions are all flat plates with the lengths of 80mm (length) x 60mm (width) x 4mm (height), and according to the test, the allowable load grade of the masonry wall bracket of the utility model can reach 8kN, while the allowable load grade of the other masonry wall bracket is only 7kN.
The provision of this void space reduces the weight and production cost of the masonry wall bracket and does not reduce the mechanical strength of the masonry wall bracket. In other words, the utility model replaces the triangular flat plate by arranging the two mutually inclined supporting rods, thereby reducing the weight and the production cost of the masonry wall bracket and simultaneously still playing the technical effect of supporting the brick exterior wall. In addition, the gap space can also reduce the thermal bridge of the masonry wall bracket, and has better energy-saving effect.
In order to facilitate the adjustment of the position of the masonry wall bracket, a bolt slot portion 150 is provided at an end of the inclined strut 130 remote from the connection portion. The bolt clamping groove part 150 is detachably connected with the bearing wall connecting part 200. The bolt clamping groove portion 150 comprises two clamping groove plates 151 which are vertically arranged in parallel at intervals, and the clamping groove plates 151 are perpendicular to the plane where the bearing wall 10 is located. The side surface of the slot plate 151 away from the connecting portion is provided with a plurality of slots 152 with different heights. Preferably, the distance between the highest card slot and the card slot is 3.5cm.
The load bearing wall connection 200 includes a first connection 210 and a second connection 220. The first connection portion 210 is disposed on a side surface of the clamping groove plate 151 away from the connection portion, and the second connection portion 220 is disposed on a side surface of the clamping groove plate 151 close to the connection portion. FIG. 6 is a front view of a first connector portion of the present utility model; fig. 7 is a side view of a first connector portion of the present utility model. As shown in fig. 6 and 7, the first connecting portion 210 is in an inverted L shape, that is, includes a connecting portion main body 212 vertically disposed and a clamping portion 211 horizontally extending above the connecting portion main body 212, a bar-shaped through hole 213 obliquely disposed is formed in the connecting portion main body 212, and the bar-shaped through hole 213 is inclined with respect to a horizontal plane, so that after the T-shaped bolt is inserted into the bar-shaped through hole 213, the position of the masonry wall bracket can be conveniently adjusted. The engaging portion 211 is configured to engage with the engaging groove 152, so as to fix the relative position of the engaging groove plate 151 to the first connecting portion 210. When the engaging portion 211 is engaged with the engaging grooves 152 of different heights, the masonry wall bracket can be placed at different heights.
The connection hole of the bearing wall connection part 200 includes a circular through hole of the second connection part 220 in addition to the bar-shaped through hole 213 of the first connection part 210. Specifically, the second connecting portion 220 is substantially square, the width of the second connecting portion is greater than the distance between the two clamping groove plates 151, a circular through hole is formed in the middle of the second connecting portion 220, the left end and the right end of the second connecting portion are bent towards the clamping groove plates 151, so that the second connecting portion is buckled outside the two clamping groove plates 151, the circular through hole is arranged corresponding to the strip-shaped through hole 213, after the bolt heads of the hexagonal bolts are fixed, the threaded portions can sequentially penetrate through the strip-shaped through hole 213, the space between the two clamping groove plates 151 and the circular through hole, and then the threaded portions are screwed down by nuts, washers and the like, so that the masonry wall bracket is fixed on the bearing wall 10. At this time, the specific positions of the masonry wall brackets can be adjusted by adjusting the relative positions of the clamping groove plate 151, the first connection portion 210 and the second connection portion 220, so that the masonry wall brackets can be freely adjusted in the height and horizontal directions, and the masonry wall brackets have high installation freedom and are very suitable for compensating structural tolerances or installation errors.
It should be added that the masonry wall bracket of the present utility model is preferably stainless steel, which has good corrosion resistance as compared to conventional masonry supports. The damage of the wall body caused by steel corrosion can be effectively avoided. Further, the tensile strength of the stainless steel is not lower than 400N/mm 2 The high-strength material enables the masonry wall bracket to have smaller cross section under the condition that the product load capacity is not reduced.
