Technical Field

[0001] The utility model belongs to the technical field of main structure construction of building engineering, and particularly relates to a waterproof coiled material end structure for a roof steel column. Background Art

[0002] With the development of the construction industry, steel structure buildings are being used more and more. Waterproofing treatment of steel columns is an inevitable link in roof waterproofing projects. The careful design and high-level construction of this link are essential to ensure the reliability and user satisfaction of the building during use.

[0003] The Chinese utility model patent currently announced is: CN217517983U, which discloses a waterproof structure based on steel columns protruding from the roof, which is provided with a concrete roof and steel columns arranged in the concrete roof, the concrete roof includes a steel truss and a floor deck; a waterstop steel plate, an expansion waterstop strip and a number of bolts are arranged on the steel column; concrete is poured in the steel column, the upper end of the steel column passes through the concrete roof, and a concrete guide wall is poured along the outer side of the bottom of the steel column of the concrete roof, a roof insulation layer is laid on the concrete roof, a water dispersion slope is formed at the upper end of the concrete guide wall, and a guide wall groove is formed at the joint of the concrete guide wall and the steel column, which is filled with waterproof sealing paste. The above arrangement solves the technical problem of poor waterproof effect of the existing steel column structure protruding from the roof.

[0004] The waterproof layer in this patent adopts waterproof membrane, but the waterproof membrane is directly exposed to the outside air. The end of the waterproof membrane is prone to warping under long-term exposure, causing water leakage along the surface of the steel column, increasing the maintenance risk. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof membrane end structure for roof steel columns, which solves the problem that an existing waterproof structure based on roof steel columns, in which the waterproof membrane is directly exposed to the outside air, the end position of the waterproof membrane is prone to warping under long-term exposure, and the hidden danger of water leakage occurs along the surface of the steel column, increasing the risk of maintenance.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a waterproof membrane capping structure for roof steel columns, including a steel truss floor deck, a steel column is arranged on the steel truss floor deck, and a flat steel is arranged on the steel column at its flashing height, and the flat steel is a galvanized steel plate. A waterproof membrane is arranged between the steel column and the steel truss floor deck, and the waterproof membrane caps on the lower surface of the flat steel. An insulation layer is arranged on the surface of the steel truss floor deck and the waterproof membrane, and a masonry protection wall is arranged around the steel column. The masonry protection wall is used to protect the membrane wrapped on the surface of the steel column, and a cement mortar protective layer is arranged on the surface of the steel truss floor deck, the insulation layer and the masonry protection wall.

[0007] The above technical scheme is adopted, by setting the steel truss floor deck, steel column, flat steel, waterproof membrane, thermal insulation layer, masonry protection wall and cement mortar protective layer. When in use, the steel column is first set on the steel truss floor deck, and the surface of the steel column is provided with galvanized flat steel as the key part of the waterproof end. Then the waterproof membrane is laid between the steel column and the steel truss floor deck to prevent water penetration and ensure the waterproof performance of the building structure. Then the thermal insulation layer is set on the surface of the steel truss floor deck and the waterproof membrane to provide thermal insulation effect and improve the energy efficiency of the building. Then the masonry protection wall is set around the steel column. Its main function is to protect the waterproof membrane wrapped on the surface of the steel column to prevent it from being physically damaged by the outside world. The cement mortar protective layer covers the surface of the steel truss floor slab, the insulation layer and the masonry protective wall, which can fill the surface unevenness, reduce surface humidity and increase surface hardness. The waterproof membrane is terminated on the lower surface of the galvanized flat steel to ensure that the end of the waterproof membrane can be firmly fixed on the steel column, effectively preventing moisture from seeping in from the end of the membrane, and avoiding the hidden danger of water leakage along the surface of the steel column due to the end of the waterproof membrane being easily opened due to long-term exposure, greatly reducing the maintenance risk.

[0008] Furthermore: a water dispersion slope is arranged on the upper surface of the cement mortar protective layer, and the water dispersion slope is arranged to be inclined downward along an end away from the steel column, and the slope of the water dispersion slope is 5°-15°.

[0009] By adopting the above technical solution, by setting up a drainage slope, when rainwater falls on the roof, it is first blocked by the waterproof membrane to prevent it from directly penetrating into the building structure. Then, the rainwater flows along the surface of the floor deck to the drainage slope. Due to the inclined design of the drainage slope, the rainwater can quickly gather and flow to the low-lying areas or drainage system, thereby effectively draining the rainwater and avoiding erosion and damage to the building by accumulated water.

[0010] Further: a waterstop steel plate is arranged in the steel bar truss floor decking plate, an expansion waterstop strip is arranged on the waterstop steel plate, and the expansion waterstop strip is in contact with the steel column.

[0011] By adopting the above technical scheme, through the arrangement of waterstop steel plates and expansion waterstop strips, the coordinated use of waterstop steel plates and expansion waterstop strips provides double waterproof protection for the building. The waterstop steel plates are mainly used to cut off and extend the water infiltration path, while the expansion waterstop strips achieve tighter sealing and waterstopping through swelling when encountering water and self-adhesive properties.

[0012] Further: an installation groove is arranged at the upper end of the masonry protection wall, a waterproof rubber ring is arranged inside the installation groove, and the waterproof rubber ring is in contact with the flat steel.

[0013] By adopting the above technical solution, by setting up an installation groove and a waterproof rubber ring, the waterproof rubber ring is designed to be installed inside the upper installation groove of the masonry protection wall to ensure that it is in close contact with the flat steel. When the waterproof rubber ring is in contact with the flat steel, due to the material characteristics and structural design of the rubber ring, an effective sealing effect can be achieved to prevent moisture from penetrating through this point.

[0014] Furthermore: the interior of the steel column is poured with concrete.

[0015] By adopting the above technical solution, concrete is poured inside the steel column. The concrete is poured inside the steel column and forms a close combination with the steel column to jointly bear the load of the building. The concrete increases the rigidity and stability of the steel column and improves its compression and bending resistance.

[0016] Further: the welding form between the flat steel and the steel column is a full weld connection.

[0017] By adopting the above technical scheme, by setting the welding method of the flat steel and the steel column, in the full weld connection, the welding operation will melt all the contact surfaces of the flat steel and the steel column, and then cool and solidify to form a complete weld. The full weld connection ensures a tight connection between the flat steel and the steel column, avoiding leakage problems caused by gaps or voids.

[0018] Further: the end of the water-stop steel plate away from the steel column is tilted upward, and the thickness of the water-stop steel plate is 3-6 mm.

[0019] By adopting the above technical solution, by setting the shape of the waterstop steel plate, the end of the waterstop steel plate away from the steel column is tilted upward, which can more effectively prevent water penetration. When water tries to enter the interior of the building through construction joints or other possible gaps, it will first encounter the waterstop steel plate. Since the steel plate is tilted upward, the water will slide down the steel plate instead of directly penetrating into the interior of the building.

[0020] Furthermore: the waterproof membrane adopts a self-adhesive waterproof membrane to wrap the lower surface of the steel truss floor deck, steel column and flat steel as a whole to form a complete waterproof barrier.

[0021] By adopting the above technical solution, by setting the material of the waterproof roll, the self-adhesive roll has excellent self-adhesiveness and can be directly adhered to the treated base surface without additional adhesive or heating treatment, and can reach the initial peel strength and be waterproof at ambient temperature.

[0022] In summary, the utility model has the following beneficial effects:

[0023] By setting up steel truss floor decking, steel columns, flat steel, waterproof membrane, thermal insulation layer, masonry protection wall and cement mortar protection layer, when in use, first the steel column is set on the steel truss floor decking, and the galvanized flat steel is set on its surface as the key part of the waterproof end, and then the waterproof membrane is laid between the steel column and the steel truss floor decking to prevent moisture penetration and ensure the waterproof performance of the building structure, and then the thermal insulation layer is set on the surface of the steel truss floor decking and the waterproof membrane to provide thermal insulation effect and improve the energy efficiency of the building, and then the masonry protection wall is set around the steel column, and its main function is to It can protect the waterproof membrane wrapped on the surface of the steel column to prevent it from being physically damaged by the outside world. The cement mortar protective layer covers the surface of the steel truss floor slab, the insulation layer and the masonry protective wall, which can fill the uneven surface, reduce surface humidity and increase surface hardness. The waterproof membrane is terminated on the lower surface of the galvanized flat steel to ensure that the end of the waterproof membrane can be firmly fixed on the steel column, effectively preventing moisture from seeping in from the end of the membrane, and avoiding the hidden danger of water leakage along the surface of the steel column due to the end of the waterproof membrane being easily opened due to long-term exposure, greatly reducing the maintenance risk.

[0024] By setting up a drainage slope, when rainwater falls on the roof, it is first blocked by the waterproof membrane to prevent it from directly seeping into the building structure. Then, the rainwater flows along the surface of the floor decking to the drainage slope. Due to the inclined design of the drainage slope, the rainwater can quickly gather and flow to low-lying areas or drainage systems, thereby effectively draining the rainwater and avoiding erosion and damage to the building by accumulated water.

[0025] Based on the above-mentioned improvements, the overall technical effect achieved by the device is a simple structure, which greatly improves the waterproof quality of the roof steel columns, avoids the hidden danger of water leakage along the surface of the steel columns due to the end of the waterproof membrane being easily opened due to long-term exposure, and greatly reduces the maintenance risk.

A cement mortar protective layer 7 is arranged on the surface of the steel truss floor deck 1, the insulation layer 5 and the masonry protection wall 6.

[0033] By arranging the steel truss floor deck 1, the steel column 2, the flat steel 3, the waterproof membrane 4, the thermal insulation layer 5, the masonry protection wall 6 and the cement mortar protection layer 7, when in use, firstly, the steel column 2 is arranged on the steel truss floor deck 1, and the galvanized flat steel 3 is arranged on the surface thereof as the key part of the waterproof end, and then the waterproof membrane 4 is laid between the steel column 2 and the steel truss floor deck 1 to prevent moisture penetration and ensure the waterproof performance of the building structure, and then the thermal insulation layer 5 is arranged on the surface of the steel truss floor deck 1 and the waterproof membrane 4 to provide a thermal insulation effect and improve the energy efficiency of the building, and then the masonry protection wall 6 is arranged around the steel column 2, and its The main function is to protect the waterproof membrane 4 wrapped on the surface of the steel column 2 to prevent it from being physically damaged by the outside world. The cement mortar protective layer 7 covers the surface of the steel truss floor slab 1, the insulation layer 5 and the masonry protective wall 6, which can fill the surface unevenness, reduce surface humidity and increase surface hardness. The waterproof membrane 4 is terminated on the lower surface of the galvanized flat steel 3 to ensure that the end of the waterproof membrane 4 can be firmly fixed on the steel column 2, effectively preventing moisture from penetrating from the end of the membrane, and avoiding the hidden danger of water leakage along the surface of the steel column 2 due to the end position of the waterproof membrane 4 being easily opened due to long-term exposure, thereby greatly reducing the maintenance risk.

[0034] refer to Figure 1 A water dispersion slope 8 is arranged on the upper surface of the cement mortar protective layer 7. The water dispersion slope 8 is arranged to be inclined downward along the end away from the steel column 2. The slope of the water dispersion slope 8 is 5°-15°. By setting the water dispersion slope 8, when rainwater falls on the roof, it is first blocked by the waterproof membrane 4 to avoid directly penetrating into the interior of the building structure. Then, the rainwater flows along the surface of the floor deck to the water dispersion slope 8. Due to the inclined design of the water dispersion slope 8, the rainwater can be quickly gathered and flow to the low-lying area or the drainage system, thereby effectively draining the rainwater and avoiding the erosion and damage of the building by the accumulated water.

[0035] refer to Figure 3A waterstop steel plate 9 is arranged in the steel truss floor decking 1, and an expansion waterstop strip 10 is arranged on the waterstop steel plate 9. The expansion waterstop strip 10 is in contact with the steel column 2. By arranging the waterstop steel plate 9 and the expansion waterstop strip 10, the coordinated use of the waterstop steel plate 9 and the expansion waterstop strip 10 provides double waterproof protection for the building. The waterstop steel plate 9 is mainly used to cut off and extend the water penetration path, while the expansion waterstop strip 10 achieves a tighter seal and waterstopping by swelling when encountering water and having self-adhesive properties.

[0036] refer to Figure 2 A mounting groove 11 is provided at the upper end of the masonry protection wall 6, and a waterproof rubber ring 12 is provided inside the mounting groove 11. The waterproof rubber ring 12 is in contact with the flat steel 3. By setting the mounting groove 11 and the waterproof rubber ring 12, the waterproof rubber ring 12 is designed to be installed inside the mounting groove 11 at the upper end of the masonry protection wall 6 to ensure that it is in close contact with the flat steel 3. When the waterproof rubber ring 12 is in contact with the flat steel 3, an effective sealing effect can be achieved to prevent moisture from penetrating through here.

[0037] refer to Figure 1 The interior of the steel column 2 is poured with concrete. By pouring concrete inside the steel column 2, the concrete is poured inside the steel column 2, forming a close combination with the steel column 2 to jointly bear the load of the building. The concrete increases the rigidity and stability of the steel column 2 and improves its compression and bending resistance.

[0038] refer to Figure 1 The welding form between the flat steel 3 and the steel column 2 is a full weld connection. By setting the welding method between the flat steel 3 and the steel column 2, in the full weld connection, the welding operation melts all the contact surfaces between the flat steel 3 and the steel column 2, and then cools and solidifies to form a complete weld. The full weld connection ensures a tight connection between the flat steel 3 and the steel column 2, avoiding leakage problems caused by gaps or voids.

By setting the shape of the waterstop steel plate 9 and the end of the waterstop steel plate 9 away from the steel column 2 is tilted upward, water penetration can be more effectively prevented. When water tries to enter the interior of the building through construction joints or other possible gaps, it will first encounter the waterstop steel plate 9. Since the steel plate is tilted upward, water will slide down the steel plate instead of directly penetrating into the interior of the building.

[0040] refer to Figure 1The waterproof membrane 4 uses a self-adhesive waterproof membrane 4 to wrap the entire lower surface of the steel truss floor deck 1, steel column 2 and flat steel 3 to form a complete waterproof barrier. By setting the material of the waterproof membrane 4, the self-adhesive membrane has excellent self-adhesion and can be directly pasted on the treated base surface. No additional adhesive or heating treatment is required to achieve the initial peeling strength and it can be waterproof at ambient temperature.
