A waterproof alarm structure for roofs and a house

Abstract

This utility model relates to a roof flood prevention alarm structure and a building thereof. The flood prevention alarm structure includes a main unit, several support units, a detection unit, and at least one counterweight unit. Its advantages lie in the use of adjustable-height brackets (such as threaded sleeve structures) in the support units, allowing for flexible adjustment of the main unit's elevation based on roof flatness and drainage height, ensuring the detection unit is always in an effective monitoring position. The adjustable performance of the support units adapts to different roof structures, addressing common flat roof variations such as height differences and irregularly shaped drainage outlets (rain hoppers). Furthermore, the support units are not forcibly connected to the roof, avoiding damage to the original structural layers, waterproofing layers, or historical features of the protected building. The counterweight unit and stabilizing unit utilize lead blocks, cast iron, and other heavy objects to increase overall stability, resisting wind disturbances in extreme weather conditions and preventing equipment displacement or tipping, while also avoiding irreversible damage to the cultural relic caused by traditional expansion bolt fixing.

Description

Technical Field

[0001] This utility model relates to the technical field of roof waterproofing, and in particular to a waterproofing alarm structure and a building for roofs. Background Technology

[0002] The Bund is dotted with numerous nationally protected buildings of significant historical and cultural value. Stylistically, these include the Neoclassical HSBC Building and the Renaissance-style Central Hotel, forming a veritable "World Architecture Expo." Historically, they bear witness to Shanghai's vicissitudes; for example, the Bank of China Building, designed and built by the Chinese themselves, embodies national spirit. Culturally, these buildings carry rich connotations of Shanghai's unique culture, serving as important symbols of the city's heritage. Today, they are popular tourist attractions, drawing countless visitors to experience the charm of history and culture.

[0003] These buildings, weathered by time, bear witness to the city's development and changes, possessing irreplaceable cultural and artistic value. In their architectural style, roof drainage often employs a flat, organized drainage system, a common practice in the preservation of historical buildings. However, due to building characteristics and environmental factors, this type of drainage system faces the risk of rainwater leakage. In particular, roof drains are prone to blockage due to the accumulation of dust, fallen leaves, and other debris, leading to potential safety hazards such as roof flooding and exceeding structural load limits, directly threatening the building's safety and lifespan.

[0004] Currently, no effective solutions have been proposed for the problems of blockage, water leakage, and threats to structural safety of the flat roof drainage systems of the Bund's national protected buildings. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a roof-mounted anti-water accumulation alarm structure and building, thereby solving the problems of blockage, water leakage, and structural safety threats in the drainage systems of flat roofs of the Bund National Heritage buildings.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Firstly, a waterproofing alarm structure for roofs is provided, comprising:

[0008] The main unit is used to install above the rainwater hopper at the roof drain outlet;

[0009] A plurality of support units are distributed on the main body unit for contacting the roof, supporting the main body unit, and allowing the main body unit to reciprocate along the axial direction of the support units.

[0010] A detection unit, located at the bottom of the main body unit, is used to detect the water level;

[0011] At least one counterweight unit is disposed above the main body unit and is movably connected to several of the support units, for reciprocating along the axial direction of the support units and for counterweighting the anti-water accumulation alarm structure.

[0012] In some embodiments, the main body unit includes:

[0013] The main component has the detection unit located below it and the counterweight unit located above it, for placement above the roof drain outlet rainwater hopper.

[0014] A plurality of first through-slot elements are distributed on the main body element and are detachably connected to the corresponding support unit.

[0015] In some embodiments, the main body unit further includes:

[0016] A first mounting element is disposed through the main body element and connected to the detection unit.

[0017] In some embodiments, the support unit includes:

[0018] A support element is provided, which is movably connected to the main body unit and the counterweight unit respectively; it is used to support the main body unit and the counterweight unit and to allow the main body unit and the counterweight unit to reciprocate along the axial direction of the support element.

[0019] A first adjusting element is movably disposed on the support element and located at the bottom end of the main body unit, for limiting the position of the main body unit;

[0020] A first locking element is movably disposed on the support element and located at the top of the main body unit, for use in conjunction with the first adjusting element to lock the main body unit;

[0021] At least one second adjusting element is movably disposed on the support element and located at the bottom end of the counterweight unit to limit the position of the counterweight unit;

[0022] At least one second locking element is movably disposed on the support element and located at the top of the counterweight unit, for cooperating with the second adjusting element to lock the counterweight unit.

[0023] In some embodiments, the detection unit includes:

[0024] A detection element is disposed at the bottom of the main body unit and is used to detect the water level.

[0025] In some embodiments, the counterweight unit includes:

[0026] A counterweight element is disposed above the main body unit and is movably connected to several of the support units, for reciprocating along the axial direction of the support units and for counterweighting the anti-water accumulation alarm structure.

[0027] A plurality of second through-slot elements are distributed on the counterweight element and are detachably connected to the corresponding support unit.

[0028] In some embodiments, the flood prevention alarm structure further includes:

[0029] A plurality of stabilizing units are respectively disposed at the bottom end of the corresponding supporting unit, for contacting the roof and stabilizing the anti-water accumulation alarm structure.

[0030] In some embodiments, the stabilizing unit includes:

[0031] A stabilizing element is disposed at the bottom end of the corresponding support unit for contacting the roof surface and stabilizing the anti-water accumulation alarm structure.

[0032] The second mounting element is disposed at the top of the stabilizing element and is detachably connected to the corresponding support unit.

[0033] In some embodiments, the stabilizing unit further includes:

[0034] An anti-slip element, disposed at the bottom end of the stabilizing element, is used to improve the anti-slip properties of the stabilizing element; and / or

[0035] A third mounting element is disposed on the stabilizing element for connection with an expansion bolt.

[0036] Secondly, a house is provided, comprising:

[0037] As described in the first aspect, the structure prevents water accumulation and provides an alarm.

[0038] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0039] 1. The support unit utilizes an adjustable-height bracket (such as a threaded sleeve structure) to flexibly adjust the elevation of the main unit according to the flatness of the roof and the drainage height, ensuring that the detection unit is always in an effective monitoring position. The adjustable performance of the support unit adapts to different roof structures, addressing complex shapes such as common height differences and irregularly shaped drainage outlets (rain hoppers) on flat roofs. Furthermore, the support unit is not forcibly connected to the roof, avoiding damage to the original structural layer, waterproof layer, or historical features of the protected building. Counterweight and stabilizing units, using lead blocks, cast iron, and other heavy objects, increase overall stability, resisting wind disturbances in extreme weather conditions and preventing equipment displacement or tipping, while also avoiding irreversible damage to the cultural relic caused by traditional expansion bolt fixing.

[0040] 2. The entire flood prevention alarm structure requires no disruption to the original roof drainage system or the installation of pre-buried pipelines. Installation is achieved solely through physical placement and gravity fixation, complying with the "minimal intervention" principle in the *Guidelines for the Protection of Chinese Cultural Relics and Historic Sites*. When the building undergoes repairs or the monitoring location changes, it can be quickly disassembled and moved, leaving no permanent traces on the roof. This "install-and-use, disassemble-and-remove" characteristic provides an ideal flood monitoring solution for national protected architectural complexes like those on the Bund, which have extremely high protection requirements. It meets modern disaster prevention needs while maximizing the preservation of the authenticity and integrity of the building's historical information.

[0041] 3. By utilizing the third mounting element of the stabilizing unit to establish a strong connection with non-cultural relic-related structures, the stabilizing unit acquires a "selective strong connection" characteristic, enabling it to function at the boundary between national protected buildings and modern extensions. For example, when there are later additions such as glass curtain walls or concrete podiums around a national protected building, the stabilizing unit can act as a "transition fulcrum," distributing the load of the flood prevention alarm structure to the modern structure. This satisfies the "zero intervention" requirement of the national protected building itself while providing comprehensive monitoring coverage for the drainage system of complex building complexes. This "new-old synergy" model is particularly suitable for mixed-use scenarios of "cultural relic buildings + modern commercial complexes" in historical districts such as the Bund.

[0138] (I) Pre-assembly

[0145] During the process, the height of the main component 11 (detection component 31) is adjusted according to the drainage height of roof A. That is, the corresponding first adjustment component 22 is twisted so that it rotates along the circumference of the corresponding support component 21 and moves along the axial direction of the support component 21 until it is adjusted to a suitable position.

[0146] Twist the corresponding first locking element 23 to rotate it circumferentially along the corresponding support element 21 while moving it axially toward the main body element 11 until it abuts against the top of the main body element 11, thereby securing the main body element 11 between the corresponding first adjusting element 22 and the corresponding first locking element 23 (see reference). Figure 8 (as shown);

[0147] Adjust the position of the corresponding support element 21 according to the flatness of roof A. After the main body element 11 (detection element 31) is adjusted to a suitable height, the corresponding first adjustment element 22 and the corresponding first locking element 23 can be twisted to move until they are separated from the bottom and top of the main body element 11 respectively.

[0148] Pull the corresponding support element 21 to move it upward or downward along the axis of the corresponding first through slot element 12 until it moves to the appropriate position. Then twist the corresponding first adjustment element 22 until it abuts against the bottom end of the main body element 11.

[0149] Twist the corresponding first locking element 23 until it abuts against the top of the main body element 11, thereby fixing the corresponding support element 21 (see reference). Figure 9 (As shown).

[0150] (III) Counterweight

[0151] Place the corresponding second adjustment element 24 on the corresponding support element 21, and twist the corresponding second adjustment element 24 so that it rotates along the circumference of the corresponding support element 21 and moves along the axial direction of the support element 21 towards the main body element 11 until it is adjusted to a suitable position.

[0152] According to the requirements, the corresponding number of counterweight elements 41 are passed through the second through slot element 42 in sequence through the corresponding support element 21 (the corresponding number of counterweight elements 41 can be increased or decreased according to the stability) until they come into contact with the second adjustment element 24.

[0153] Place the corresponding second locking element 25 on the corresponding support element 21, and twist the corresponding second locking element 25 so that it rotates along the circumference of the corresponding support element 21 and moves along the axial direction of the support element 21 toward the counterweight element 41 until it abuts against the top of the counterweight element 41, thereby securing the counterweight element 41 between the corresponding second adjusting element 24 and the corresponding second locking element 25.

[0154] The advantages of this utility model are:

[0155] 1. The support unit utilizes an adjustable-height bracket (such as a threaded sleeve structure) to flexibly adjust the elevation of the main unit according to the flatness of the roof and the drainage height, ensuring that the detection unit is always in an effective monitoring position. The adjustable performance of the support unit adapts to different roof structures, addressing complex shapes such as common height differences and irregularly shaped drainage outlets (rain hoppers) on flat roofs. Furthermore, the support unit is not forcibly connected to the roof, avoiding damage to the original structural layer, waterproof layer, or historical features of the protected building. Counterweight and stabilizing units, using lead blocks, cast iron, and other heavy objects, increase overall stability, resisting wind disturbances in extreme weather conditions and preventing equipment displacement or tipping, while also avoiding irreversible damage to the cultural relic caused by traditional expansion bolt fixing.

[0156] 2. The entire flood prevention alarm structure requires no disruption to the original roof drainage system or the installation of pre-buried pipelines. Installation is achieved solely through physical placement and gravity fixation, complying with the "minimal intervention" principle in the *Guidelines for the Protection of Chinese Cultural Relics and Historic Sites*. When the building undergoes repairs or the monitoring location changes, it can be quickly disassembled and moved, leaving no permanent traces on the roof. This "install-and-use, disassemble-and-remove" characteristic provides an ideal flood monitoring solution for national protected architectural complexes like those on the Bund, which have extremely high protection requirements. It meets modern disaster prevention needs while maximizing the preservation of the authenticity and integrity of the building's historical information.

Generally, the radial dimension of the anti-slip element 53 is equal to the maximum radial dimension of the stabilizing element 51, and the axial dimension of the anti-slip element 53 is smaller than the axial dimension of the stabilizing element 51.

Specifically, the mounting plate is disposed at the bottom end of the stabilizing element 51 and connected to the stabilizing element 51; the second mounting hole is disposed through the mounting plate for the expansion bolt to pass through.

[0184] In some embodiments, the third mounting element 54 is fixedly connected to the stabilizing element 51, including but not limited to welding.

[0185] In some of these embodiments, the third mounting element 54 is made of metal.

[0186] The method of using this utility model is as follows:

[0187] (I) Pre-assembly

[0188] Twist the second locking element 25, the second adjusting element 24, and the first locking element 23 on the support element 21 in sequence until they are removed.

[0189] According to the requirements, the corresponding number of support elements 21 are sequentially passed through the corresponding first through slot element 12 provided in the main body element 11 (the corresponding number of support elements 21 can be increased or decreased according to stability) until they come into contact with the first adjustment element 22.

[0190] The first locking element 23 is placed on the corresponding support element 21 so that the main body element 11 is located between the corresponding first adjusting element 22 and the corresponding first locking element 23.

[0191] Install the corresponding stabilizing element 51 to the bottom end of the corresponding supporting element 21 via the second mounting element 52 until it is tightened.

[0192] The detection element 31 is placed on the first mounting element 13 and fixed by bolt connection.

[0193] (2) Placement

[0194] Place the pre-assembled anti-water accumulation alarm structure at the designated location on roof A, that is, above the rainwater hopper B;

[0195] During the process, the height of the main component 11 (detection component 31) is adjusted according to the drainage height of roof A. That is, the corresponding first adjustment component 22 is twisted so that it rotates along the circumference of the corresponding support component 21 and moves along the axial direction of the support component 21 until it is adjusted to a suitable position.

[0196] Twist the corresponding first locking element 23 to rotate it circumferentially along the corresponding support element 21 while moving it axially toward the main body element 11 until it abuts against the top of the main body element 11, thereby securing the main body element 11 between the corresponding first adjusting element 22 and the corresponding first locking element 23 (see reference). Figure 8 (as shown);

[0197] The corresponding third mounting element 54 is connected and fixed to the roof A using the corresponding expansion bolts;

[0198] Adjust the position of the corresponding support element 21 according to the flatness of roof A. After the main body element 11 (detection element 31) is adjusted to a suitable height, the corresponding first adjustment element 22 and the corresponding first locking element 23 can be twisted to move until they are separated from the bottom and top of the main body element 11 respectively.

[0199] Pull the corresponding support element 21 to move it upward or downward along the axis of the corresponding first through slot element 12 until it moves to the appropriate position. Then twist the corresponding first adjustment element 22 until it abuts against the bottom end of the main body element 11.

[0200] Twist the corresponding first locking element 23 until it abuts against the top of the main body element 11, thereby fixing the corresponding support element 21 (see reference). Figure 9 (as shown);

[0201] The corresponding third mounting element 54 is connected and fixed to the roof A using the corresponding expansion bolts.

[0202] (III) Counterweight

[0203] The usage method is basically the same as that in Example 1 (III), and will not be repeated here.

[0204] The advantage of this invention lies in its use of a third mounting element of the stabilizing unit to create a strong connection with non-cultural relic-related structures. This gives the stabilizing unit a "selective strong connection" characteristic, allowing it to function at the boundary between nationally protected buildings and modern extensions. For example, when there are later additions such as glass curtain walls or concrete podiums around a nationally protected building, the stabilizing unit can act as a "transition fulcrum," distributing the load of the flood prevention alarm structure to the modern structure. This satisfies the "zero intervention" requirement of the nationally protected building itself while providing comprehensive monitoring coverage for the drainage system of complex building complexes. This "new-old synergy" model is particularly suitable for mixed-use scenarios of "cultural relic buildings + modern commercial complexes" in historical districts such as the Bund.
