Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat preservation board installation and construction, in particular to a heat preservation board installation structure outside a beam at an overhanging eaves. Background Art
[0002] The thermal insulation integrated board has been widely used in thermal insulation of walls, roofs, floors, etc. due to its advantages of low density, low thermal conductivity, shock resistance, corrosion resistance, mildew resistance, and good construction performance. In the prior art, the thermal insulation board is fixed to the steel bars of the beam structure by anchor bolts, and the thermal insulation board is pressed on the steel bars of the cantilevered eaves structure. The steel bars of the cantilevered eaves structure usually include a lower steel mesh, an upper steel mesh, and horse stool bars arranged between the lower steel mesh and the upper steel mesh. The thermal insulation board is directly located on the upper steel mesh, and the upper steel mesh is supported only by the horse stool bars arranged at intervals. It will cause the upper steel mesh to sink, and then, for the position where the upper steel mesh is in direct contact with the insulation board, the upper steel mesh loses the protection of the steel bar protective layer, the steel bars are prone to rust, and the strength and rigidity of the concrete structure will decrease; for the position where the upper steel mesh is not in contact with the insulation board, the thickness of the steel bar protective layer becomes larger, and the concrete at the cantilevered eaves is prone to cracking, which reduces the construction quality of the cantilevered eaves. At the same time, due to the increase in the thickness of the steel bar protective layer, the installation position of the insulation integrated board will also be affected, which will affect the thermal insulation performance of the structure and increase the subsequent repair costs. Utility Model Content
[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an insulation board installation structure outside the cantilever beam which can ensure the accurate installation position of the insulation board and does not affect the quality of the cantilever eaves structure.

[0019] The present invention is further described below in conjunction with specific embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.
[0020] like Figure 1 As shown in the prior art, the insulation board 4 is directly pressed on the eaves structural steel bar 3 during installation, which easily causes the eaves structural steel bar 3 to deform, affects the thickness of the steel bar protective layer, and further affects the eaves construction quality. Figure 1 , Figure 4 As shown, the present embodiment discloses an insulation board installation structure for the outer side of the beam at the cantilevered eaves, including a beam structure steel bar 1 and a cantilevered eaves structure steel bar 3, an insulation board 4 is fixed to the outer side of the beam structure steel bar 1 by anchor bolts 5 arranged at intervals, a cantilevered eaves casting bottom plate for supporting the cantilevered eaves structure steel bar 3 is arranged at the lower side of the cantilevered eaves structure steel bar 3, the cantilevered eaves structure steel bar 3 includes an upper steel bar mesh 301 and a lower steel bar mesh 302, a horse stool bar 303 is arranged between the upper steel bar mesh 301 and the lower steel bar mesh 302; a plurality of cantilevered eaves casting bottom plates are also arranged at intervals The pad 6 for supporting the insulation board 4 is located in the grid of the upper steel mesh 301 and the lower steel mesh 302, and the height of the pad 6 is equal to the thickness of the eaves; wherein the spacing between the pads 6 is not greater than 1000 mm; the upper steel mesh 301 and the lower steel mesh 302 are both formed by binding transverse bars and longitudinal bars, wherein the longitudinal bars in the upper steel mesh 301 and the lower steel mesh 302 are arranged parallel to the lower edge of the insulation board 4; the pad 6 is a concrete pad 6, and the concrete model is consistent with the concrete model of the eaves structure.
[0021] During construction, first tie the beam structure reinforcement 1; then, support the cantilever eaves casting formwork 2 and tie the cantilever eaves structure reinforcement 3, and set pads 6 at intervals below the installation position of the insulation board 4; then, install the insulation board 4, press the pads 6 at the bottom edge of the insulation board 4, and fix the insulation board 4 to the beam structure reinforcement 1 on the side close to the beam structure reinforcement 1 through the anchor bolts 5 set at intervals; finally, set the beam casting formwork, and cast the concrete of the beam structure and the cantilever eaves structure.
[0022] Embodiment 2, as Figure 3As shown, the installation structure of the insulation board 4 on the outside of the beam at the eaves of the utility model is also applicable to a double-layer eaves structure. For the sake of aesthetics, many building exterior walls are designed with double-layer eaves. To avoid the cold and hot bridge effect, an insulation board 4 needs to be arranged between the double-layer eaves. As in Example 1, when a double-layer eaves structure is involved, the lower side of the insulation board 4 abuts against the pad 6, and the upper side abuts against the lower side of the casting bottom plate of the upper eaves.
[0023] Embodiment three, as Figure 2 On the basis of Example 1, in some constructions, due to the demand for structural strength, it is necessary to add additional steel bars 304 to the structural steel bars of the cantilever eaves. The additional steel bars 304 are tied and fixed to the upper steel mesh 301 and the lower steel mesh 302, and the additional steel bars 304 are arranged parallel to the insulation board 4; due to the presence of the additional steel bars 304, the cantilever eaves structural steel bars 3 are more dense, and the pad 6 is not easy to place. If the pad 6 is too small, it will not provide a good supporting effect on the insulation board 4; therefore, in this embodiment, the longitudinal section of the pad 6 is an inverted isosceles trapezoid, and the left and right sides of the pad 6 are vertical planes, and the left and right sides are respectively clamped and fixed by the additional steel bars 304, the upper steel mesh 301 and the longitudinal steel bars in the lower steel mesh 302; the pad 6 with an inverted trapezoidal cross-section design is convenient for inserting dense cantilever eaves structural steel bars 3, and the presence of the additional steel bars 304 facilitates further fixing the pad 6.
[0024] Embodiment 4, as Figure 5 In this embodiment, a slot 601 for inserting the insulation board 4 is provided on the cushion block 6; the accuracy of the installation position of the insulation board 4 is ensured, which is conducive to ensuring the construction quality. At the same time, the double-layer fixation through the slot 601 and the anchor bolt 5 can avoid displacement of the insulation board 4 when pouring concrete.
[0025] Furthermore, the front, rear, left and right sides of the pad 6 are all rough surfaces, which facilitates better combination with the poured concrete and improves the quality of the cantilever eaves structure.
[0026] The utility model arranges a cushion block 6 under the insulation board 4 to prevent the weight of the insulation board 4 from directly pressing on the steel bars 3 of the cantilevered eaves structure, thereby preventing the steel bars 3 from deforming, thereby ensuring the construction quality of the cantilevered eaves, improving the appearance quality of the cantilevered eaves construction, and reducing the cost of later repairs; the thickness of the steel bar protective layer is ensured, the insulation board 4 is accurately installed, and the thermal insulation performance of the structure is improved.
[0027] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
