Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a building structure with dual performances of heat preservation and fire prevention. Background Art

[0002] Building structure refers to the entity of a building and its corresponding components. It is the load-bearing skeleton of various engineering entities and the force support system of a building. It can also be regarded as the "skeleton" of a building. The design and construction of building structures are crucial to ensuring the safety, stability and comfort of buildings. However, the existing building structures still have certain defects in actual use: when achieving lightweight construction, brick-wood structures and pure wood structures are often required. Due to the fire resistance of the wood structure itself, it often leads to the inability to completely block the temperature in the structure. The structure is extremely susceptible to fire and structural problems occur. Therefore, a building structure with both thermal insulation and fire resistance is required. Summary of the invention

[0003] The utility model aims to provide a building structure with dual performances of heat preservation and fire prevention, and the building structure can perform temperature insulation on the wooden structure to prevent it from being affected by fire.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A building structure with dual performances of heat preservation and fire prevention, comprising a prefabricated panel body composed of a heat preservation layer and a fire prevention layer for heat preservation and fire prevention of a wall, and a butt support for embedding and supporting the prefabricated panel body;

[0006] The thermal insulation layer includes a mortar leveling layer for smoothing out unevenness and cracks on the wall surface, a bonding layer, and an expanded polystyrene board for thermal insulation, and a pre-buried groove for placing a water pipe and a sprinkler head is provided on the surface of the expanded polystyrene board away from the bonding layer;

[0007] The fireproof layer comprises a fireproof board, a glass fiber mesh cloth and a sealing board which are laminated in sequence.

[0008] Furthermore, a steel wire mesh for preventing cracking is provided between the bonding layer and the expanded polystyrene board.

[0009] Furthermore, the adhesive layer is white latex.

[0010] Furthermore, the outer surface of the fireproof layer is also provided with expansion bolts for fixing the fireproof layer and the thermal insulation layer to the wall.

[0011] Furthermore, a placement groove corresponding to the position of the sprinkler head is opened in the center of the fireproof layer.

[0012] Furthermore, a partition net is provided on one side of the placement groove away from the expanded polystyrene board.

[0013] Furthermore, a plurality of water outlets are arranged on a side of the water spray head away from the expanded polystyrene board.

[0014] Furthermore, there are four water outlets, and their diameters are the same.

[0015] Furthermore, the water pipes are divided into two groups, one group is connected to both sides of the water spray head horizontally, and the other group is connected to both sides of the water spray head longitudinally.

[0016] Furthermore, the four sides of the docking bracket are all provided with connection grooves for clamping with the prefabricated board body and connection holes for the water supply pipe to pass through.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model performs mortar leveling on the outer surface of the wall, smoothes the grooves and cracks on the outer surface of the wall, and then bonds the expanded polystyrene board through the bonding layer to form a thermal insulation layer, and simultaneously uses a docking bracket to fix the expanded polystyrene board. After the thermal insulation layer is fixed, a pre-buried groove is cut on the expanded polystyrene board, a water pipe and a sprinkler head are placed in the pre-buried groove, and then both sides of the fireproof board of the fireproof layer are bonded with glass fiber mesh cloth to improve the tensile strength and fire resistance. When the external environment is on fire, the water pipe in the pre-buried groove collects water sources at the sprinkler head, and the water outlet of the sprinkler head cools down the area around the fireproof layer, thereby reducing the influence of high temperature on the fireproof layer and the thermal insulation layer, so as to reduce the damage of the fire to the two layers.

[0019] Furthermore, a steel wire mesh is arranged between the adhesive layer and the expanded polystyrene board of the utility model, and the steel wire mesh can effectively prevent cracks from occurring in the wall body bonded thereto, thus having the function of heat preservation and crack prevention.

[0020] Furthermore, the utility model arranges expansion bolts on the outer surface of the fireproof layer, which penetrate inwardly through the fireproof layer and the thermal insulation layer and finally fix the thermal insulation layer and the fireproof layer to the wall, and further fixes the thermal insulation layer and the fireproof layer through the sealing plate and the expansion bolts.

[0021] Furthermore, a placement groove corresponding to the position of the water sprinkler head is provided in the center of the fireproof layer, thereby preventing the protrusion of the water sprinkler head from affecting the fit between the thermal insulation layer and the fireproof layer.

[0029] The present invention will be further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0030] See also Figure 1 The utility model includes a prefabricated panel body 1 and a docking bracket 2, wherein the prefabricated panel body 1 is a finished product or a semi-finished product that is fully or semi-processed in a factory. When in use, the matching structure is directly produced in the factory by measuring the building area. The outer surface of the prefabricated panel body 1 is installed with a docking bracket 2 for supporting the prefabricated panel body 1.

[0031] See also Figure 2The prefabricated board body 1 includes an insulation layer 14 and a fireproof layer 15, wherein the insulation layer 14 includes a mortar leveling layer 5, an adhesive layer 6, a wire mesh 7 and an expanded polystyrene board 8. One side of the mortar leveling layer 5 is bonded to the wall 4, and the other side is coated with the adhesive layer 6. The wire mesh 7 is arranged on the side of the adhesive layer 6 away from the mortar leveling layer 5, and the expanded polystyrene board 8 is bonded to the pair of sides of the wire mesh 7 away from the adhesive layer 6. During installation, in order to prevent the dents and protrusions on the wall 4 from affecting the bonded area, the wall is smoothed with mortar to form a layer of mortar leveling layer 5 with strong adhesion. The adhesive layer 6 is specifically white latex. After the adhesive layer 6 is applied to the outer surface of the mortar leveling layer 5, the wire mesh 7 is embedded in the adhesive layer 6, and then the expanded polystyrene board 8 is connected to the adhesive layer 6. The fireproof layer 15 includes a fireproof board 9, a glass fiber mesh cloth 10, a sealing board 11 and an expansion bolt 12. The fireproof board 9 is fitted on the side of the expanded polystyrene board 8 away from the steel wire mesh 7. The side of the fireproof board 9 away from the expanded polystyrene board 8 is bonded with the glass fiber mesh cloth 10. The side of the glass fiber mesh cloth 10 away from the fireproof board 9 is provided with a sealing board 11. The expansion bolt 12 is installed on the sealing board 11. When installing, the fireproof board 9 is made of gypsum board material, which can be more conveniently connected with the expansion bolt 12 when drilling holes for installation. The polystyrene boards 8 are connected to each other, and at the same time, when they come into contact with flames, they can effectively retard and prevent the flame from affecting the protected expanded polystyrene board 8. The fiberglass mesh cloth 10 is adhered to the outer surface of the fireproof board 9, thereby providing the fireproof board 9 with stronger stability and tensile resistance to prevent the fireproof board 9 from being damaged by external force impact. At the same time, the insulation layer 14 and the fireproof layer 15 are encapsulated in the docking bracket 2 through the sealing plate 11, and the two are fixed to the wall 4 by the expansion bolts 12 to prevent them from falling off.

[0032] See also Figure 3 A placement groove 301 is provided at the center of the fireproof layer 15. The placement groove 301 penetrates the fireproof layer 15 and is used to place the sprinkler head 13. A partition net 3 is provided on the side of the placement groove 301 away from the expanded polystyrene board 8. Figure 4 The upper and lower sides and the left and right sides of the sprinkler head 13 are connected to water pipes 1302. The two groups of water pipes 1302 are of the same size and are connected to an external water source. Figure 5 The expanded polystyrene board 8 is block-shaped, and its surface in contact with the fireproof layer 15 is provided with a pre-buried groove 801, which is designed according to actual needs and is used to place a water pipe 1302 and a sprinkler head 13. The sprinkler head 13 is also provided with a water outlet 1301 on the side away from the expanded polystyrene board 8. There are four water outlets 1301 with the same diameter. When the external environment is on fire, the valve is opened, and the water source is poured into the sprinkler head 13 through the water pipe 1302, and then overflows from the water outlet 1301 to the outer surface of the fireproof layer 15, thereby blocking the temperature around the fireproof layer 15 to protect the thermal insulation layer 14 from being burned by the flame.

[0033] See also Figure 6 The docking bracket 2 is frame-shaped, and the prefabricated panel body 1 is embedded in it. The four sides of the docking bracket 2 are provided with connecting grooves 201 for the prefabricated panel body 1 and the docking bracket 2 to be clamped and fixed. Two connecting grooves 201 are symmetrically arranged on each side, and a connecting hole 202 is also arranged in the middle of the two connecting grooves 201. The water pipe 1302 passes through the connecting hole 202 and is connected to a water source outside.

[0034] When in use, the room area is measured, and the prefabricated panel body 1 is processed in the factory according to the measured data, and then the wall 4 is leveled with mortar, so that the dents and protrusions on the wall 4 are smoothed, thereby preventing the problem of the wall 4 from affecting the overall structure after installation, and avoiding displacement, cracks, etc. After the wall 4 is leveled, an adhesive layer 6 is applied on the mortar leveling layer 5, and before the adhesive layer 6 solidifies, the wire mesh 7 is attached to the adhesive layer 6. After the wire mesh 7 is fixed, the adhesive layer is reapplied, and the expanded polystyrene board 8 is attached to the mortar leveling layer 5 to form a thermal insulation layer 14. In the bonding structure, the docking bracket 2 is placed around the expanded polystyrene board 8, and the supporting thin film on both sides of the expanded polystyrene board 8 is fixed. The weak point is supported and fixed to the wall 4 by steel nails. After the installation of the expanded polystyrene board 8 is completed, the embedded groove 801 is cut on the outer surface of the expanded polystyrene board 8, and the water pipe 1302 and the connected sprinkler head 13 are placed inside the embedded groove 801. After the placement is completed, the fireproof board 9 is adhered to the expanded polystyrene board 8. After the installation of the fireproof board 9 is completed, the glass fiber mesh cloth 10 is adhered to the outside of the fireproof board 9, and the inner surface of the sealing board 11 is coated with adhesive and bonded to the glass fiber mesh cloth 10 on the outside of the fireproof board 9. The fireproof layer 15 is installed, and the expansion bolts 12 are successively passed through the fireproof layer 15 and the thermal insulation layer 14 and fixed to the wall 4 to complete the installation of the overall structure of the prefabricated board body 1.
