Description

Technical Field

[0001] This application relates to the field of expansion joint construction, and in particular to an integrated waterproof concealed expansion joint construction device and construction method for roofs. Background Technology

[0002] Buildings often deform under the influence of external factors, leading to cracks or even damage. Expansion joints are structural joints reserved to address this situation. Expansion joints can be divided into three types: expansion joints, settlement joints, and seismic joints. However, many buildings now take these three types of joints into account, a concept known as "three joints in one".

[0003] In related technologies, for roofs that are not accessible to people, a low wall or a waterproof retaining wall is usually built at the expansion joints. Then, the workers will cover the joints with aluminum panels and use additional roofing membrane to waterproof them. During installation, adjacent aluminum panels are often welded together.

[0004] Regarding the aforementioned technologies, the inventors believe that after prolonged use, the welds between adjacent aluminum plates are prone to corrosion and breakage, thus creating leakage points and posing a hidden danger to roof waterproofing. Summary of the Invention

[0005] To improve the waterproofing effect of roofs, this application provides an integrated waterproof concealed expansion joint construction device and construction method for roofs.

[0006] The integrated waterproof concealed expansion joint construction device for roofs provided in this application adopts the following technical solution:

[0007] An integrated waterproof concealed expansion joint construction device for roofs includes a first embedded strip on the inner wall of one side of the expansion joint, a second embedded strip on the inner wall of the other side of the expansion joint, and a waterproof component disposed between the first and second embedded strips. The waterproof component includes an installation plate disposed between the first and second embedded strips and waterproof strips disposed on both sides of the installation plate. The first embedded strip has a first moving groove for sliding cooperation with the installation plate, and the second embedded strip has a second moving groove for sliding cooperation with the installation plate. The first embedded strip is provided with a locking component for fixing the installation plate, and the installation plate is provided with a support component for supporting the waterproof strips.

[0008] By adopting the above technical solution, when constructing roof expansion joints, operators first install the first and second embedded strips, then install the waterproof strip onto the mounting plate. The operator pushes the mounting plate into the first and second moving slots, and uses locking components to fix the position of the mounting plate and the waterproof strip. The operator then uses supporting components to ensure that the outer surface of the waterproof strip is tightly attached to the first and second embedded strips. The cooperation between the waterproof strip and the first and second embedded strips helps prevent rainwater from entering the expansion joint, and the double-layer waterproof strip further improves the waterproofing effect of the roof.

[0009] Preferably, the support assembly includes a fixed sleeve fixedly connected to both sides of the mounting plate, a support column slidably inserted in the fixed sleeve for abutting against the waterproof strip, and a bidirectional screw rotatably mounted on the mounting plate. The two ends of the bidirectional screw are respectively inserted into the adjacent support columns. The bidirectional screw is threadedly engaged with the support columns, and the mounting plate is provided with a drive assembly for driving the bidirectional screw to rotate.

[0010] By adopting the above technical solution, the operator uses the drive assembly to rotate the bidirectional lead screw. The setting of the fixed sleeve helps to limit the rotation of the support column. The bidirectional lead screw causes the two support columns at both ends to move away from each other. The support columns push the waterproof belt to move until the waterproof belt is taut and the surface of the waterproof belt abuts against the first embedded part and the second embedded part.

[0011] Preferably, an arc-shaped plate is installed on the end of the support column away from the fixed sleeve, and a plurality of first springs are provided between the support column and the arc-shaped plate. One end of the first spring is fixedly connected to the arc-shaped plate, and the other end of the first spring is fixedly connected to the support column.

[0012] By adopting the above technical solution, the arc-shaped plate is conducive to fitting the waterproof strip and improving the tension of the waterproof strip. The first spring provides a certain degree of adjustment space for the waterproof strip. When the distance between the first embedded part and the second embedded part changes, the first spring can keep the waterproof strip in a taut state.

[0013] Preferably, the drive assembly includes a drive pulley spaced apart within the mounting plate and a driven pulley fixedly sleeved on the bidirectional lead screw. The drive pulley is rotatably connected to the mounting plate, and a synchronous belt is wound between the drive pulley and the driven pulley. A power assembly for driving the drive pulley to rotate is provided on the first embedded strip.

[0014] By adopting the above technical solution, the operator uses the power unit to rotate the driving pulley, which in turn causes the timing belt to rotate, which in turn causes the driven pulley to rotate, which in turn causes the bidirectional lead screw to rotate, thereby driving the support column to move, and finally achieving the tensioning of the waterproof belt.

[0015] Preferably, the power assembly includes a drive rod disposed on the first embedded strip and a knob mounted on the drive rod. The end of the drive rod away from the knob extends into the mounting plate. The drive pulley has a slot for interlocking with the drive rod. A limiting component for restricting the rotation of the drive rod is disposed in the first embedded strip.

[0016] By adopting the above technical solution, the operator presses down the knob, which drives the drive rod to move until the end of the drive rod away from the drive rod is inserted into the slot on the drive pulley. Then, the operator rotates the knob, which drives the drive rod to rotate. The drive rod and the slot make the drive gear rotate. After the operator uses the power component to tighten the waterproof belt, the operator then uses the limiting component to limit the rotation of the drive rod, thereby preventing the drive rod from rotating in the opposite direction.

[0017] Preferably, the drive rod includes an installation sleeve that slides through the first embedded strip, a plug rod that slides through the installation sleeve, and a second spring that is fixedly connected to the plug rod. The other end of the second spring is fixedly connected to the inner end face of the installation sleeve. The upper surface of the first embedded strip is provided with a rectangular groove for engaging with the knob.

[0018] By adopting the above technical solution, the installation sleeve, the plug rod, and the second spring are designed to facilitate the operator's adjustment of the length of the drive rod. When the operator turns the knob, the knob drives the installation sleeve to rotate, which in turn causes the plug rod to rotate. When the operator presses the knob until it enters the rectangular groove, the second spring is in a compressed state. The cooperation between the rectangular groove and the knob helps to prevent rainwater from entering the expansion joint along the drive rod.

[0019] Preferably, a clamping block is provided inside the first embedded strip, an installation groove for sliding cooperation with the clamping block is provided on the inner top surface of the first moving groove, a sliding groove for sliding cooperation with the installation sleeve is provided on the inner top surface of the installation groove, an abutment block is fixedly connected to the bottom of the installation sleeve, the plug rod passes through the clamping block, an iron block is embedded inside the clamping block, and a magnet for attracting the iron block is embedded on the inner top surface of the installation groove.

[0020] By adopting the above technical solution, when the operator presses down the knob, the knob drives the installation sleeve and the plug rod to move until the plug rod is inserted into the active drive. The operator continues to press down the knob, and the knob drives the installation sleeve to move. At this time, the second spring is in a compressed state. The movement of the installation sleeve causes the abutment block to move, and the abutment block pushes the pressing block to move. The bottom surface of the pressing block abuts against the upper surface of the mounting plate, thereby improving the stability of the mounting plate. The setting of the iron block and magnet helps to prevent the pressing block from directly detaching from the mounting groove.

[0021] Preferably, the limiting component includes a limiting block slidably passing through the inner wall of the slide groove, a fixing block fixedly connected to the limiting block, and a third spring fixedly connected to the fixing block. The inner wall of the slide groove is provided with a guide groove for sliding cooperation with the limiting block, and the inner wall of the guide groove is provided with a reset groove for sliding cooperation with the fixing block. The end of the third spring away from the fixing block is fixedly connected to the inner end face of the reset groove. The mounting sleeve is provided with a limiting hole for insertion cooperation with the limiting block. The ends of the abutment block and the limiting block that are close to each other are provided with inclined surfaces, and the inclined surfaces of the limiting block and the abutment block that are close to each other match.

[0022] By adopting the above technical solution, the operator pushes the knob to lower, the knob drives the installation sleeve to move, the installation sleeve drives the abutment block to move, the inclined surface of the abutment block cooperates with the inclined surface of the limit block, the abutment block causes the limit block to enter the guide groove, the limit block drives the fixing block to move, at this time the third spring is in a compressed state. When the installation sleeve continues to lower, when the limit block is aligned with the limit hole on the installation sleeve, the fixing block moves under the elastic force of the third spring, the fixing block drives the limit block to move until the limit block is inserted into the limit hole, thereby restricting the rotation and movement of the installation sleeve.

[0023] Preferably, the first embedded strip is provided with a first corrugated groove for guiding the movement of the waterproof strip, the second embedded strip is provided with a second corrugated groove for guiding the movement of the waterproof strip, and a water-absorbing expansion strip for abutting against the waterproof strip is installed on the inner sidewall of the first corrugated groove and the second corrugated groove that are close to each other.

[0024] By adopting the above technical solution, the setting of the first and second corrugated grooves is beneficial to guiding the movement of the waterproof strip on the one hand, and to making the waterproof strip form a corrugated shape on the other hand, so that the waterproof strip is closely attached to the first and second embedded strips. When the water-absorbing expansion strip absorbs water, the water-absorbing expansion strip will expand further, thereby sealing the gap between the waterproof strip and the inner wall of the first and second corrugated grooves, thereby further reducing the possibility of rainwater entering the expansion joint.

[0025] The construction method for integrated waterproof concealed expansion joints on roofs provided in this application adopts the following technical solution:

[0026] The construction method for integrated waterproofing and concealed expansion joints on roofs includes the following steps:

[0027] S1. When pouring roof concrete, the first embedded strip and the second embedded strip are installed at predetermined positions;

[0028] S2. Install waterproof tape on both sides of the mounting plate;

[0029] S3. Insert the mounting plate between the first embedded strip and the second embedded strip in sequence until the waterproof strip fills all the expansion joints;

[0030] S4. Insert the drive rod into the first embedded strip until the plug rod is inserted into the strip groove. Rotate the knob to drive the drive rod and the drive pulley to rotate. The drive pulley rotates the driven gear and the double screw through the synchronous belt, thereby causing the support column to drive the first spring and the arc plate to move until the two ends of the waterproof strip abut against the first embedded strip and the second embedded strip respectively.

[0031] S5. Press the knob down until it enters the rectangular groove. The knob drives the drive rod and the abutment block to move, thereby causing the clamping block to press against the mounting plate and the limiting block to insert into the limiting hole.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. When constructing the roof expansion joint, the operator first installs the first and second embedded strips. Then, the operator installs the waterproof strip onto the mounting plate. The operator pushes the mounting plate into the first and second moving slots. The operator uses the locking components to fix the position of the mounting plate and the waterproof strip. The operator then uses the support components to ensure that the outer surface of the waterproof strip is tightly attached to the first and second embedded strips. The cooperation between the waterproof strip and the first and second embedded strips helps to prevent rainwater from entering the expansion joint. The double-layer waterproof strip further improves the waterproofing effect of the roof.

[0034] 2. The curved plate is designed to fit the waterproof strip and improve its tension. The first spring provides a certain degree of adjustment space for the waterproof strip. When the distance between the first and second embedded parts changes, the first spring ensures that the waterproof strip remains taut.

[0035] 3. When the operator presses down the knob, the knob moves the mounting sleeve and the plug rod until the plug rod is inserted into the active drive. The operator continues to press down the knob, which moves the mounting sleeve. At this time, the second spring is in a compressed state. The movement of the mounting sleeve causes the abutment block to move. The abutment block pushes the clamping block to move. The bottom surface of the clamping block abuts against the upper surface of the mounting plate, thereby improving the stability of the mounting plate. The setting of the iron block and magnet helps to prevent the clamping block from directly detaching from the mounting groove. Attached Figure Description

[0055] The implementation principle of the roof integrated waterproof concealed expansion joint construction device in this application embodiment is as follows: When the operator is constructing the roof expansion joint, the operator first installs the first embedded strip 1 and the second embedded strip 2. Then, the operator installs the waterproof tape 31 onto the mounting plate 32. The operator pushes the mounting plate 32 into the first moving groove 12 and the second moving groove 21. The ball bearings 22 facilitate the operator's movement of the mounting plate 32. When the mounting plate 32 reaches the designated position, the operator inserts the drive rod 61 into the first embedded strip 1. The operator presses down the knob 62, which drives the mounting sleeve 611 and the plug rod 612 to move until the plug rod 612 is inserted into the strip groove 54 of the drive pulley 51. The operator rotates knob 62, which in turn rotates mounting sleeve 611. Mounting sleeve 611 then rotates plug rod 612 and drive pulley 51. Drive pulley 51, via synchronous belt 53, causes driven pulley 52 to rotate. Driven pulley 52 then rotates bidirectional lead screw 43, which in turn drives adjacent support column 42 to move. Support column 42 drives first spring 45 and arc plate 44 to support waterproof strip 31, thereby causing waterproof strip 31 to press against first embedded strip 1 and second embedded strip 2. The cooperation between waterproof strip 31 and first embedded strip 1 and second embedded strip 2 helps prevent rainwater from entering the expansion joint. The double-layer waterproof strip 31 further improves the waterproofing effect of the roof.

[0056] Next, the operator continues to press down knob 62 until it is inserted into the rectangular groove 14. The moving sleeve 611 causes the abutment block 63 to move. The movement of the abutment block 63, through the inclined surface engagement, allows the limiting block 71 to enter the guide groove 75. Simultaneously, the movement of the abutment block 63 pushes the pressing block 16 to move. When the limiting block 71 is aligned with the limiting hole 74, the fixing block 72, under the action of the third spring 73, drives the limiting block 71 to insert into the limiting hole 74. The engagement between the limiting block 71 and the limiting hole 74 helps to restrict the movement of the mounting sleeve 611. When knob 62 is fully inserted into the rectangular groove 14, the abutment block 63 drives the pressing block 16 to press against the mounting plate 32, thereby improving the stability of the mounting plate 32.

[0057] This application also discloses a construction method for integrated waterproof concealed expansion joints in roofs. The construction method for integrated waterproof concealed expansion joints in roofs includes the following steps:

[0058] S1. When pouring roof concrete, embed the first embedded strip 1 and the second embedded strip 2 at the predetermined positions;

[0059] S2. Install waterproof strips 31 on both sides of the mounting plate 32 respectively;

[0060] S3. Insert the mounting plate 32 between the first embedded strip 1 and the second embedded strip 2 in sequence until the waterproof strip 31 fills all the expansion joints;

[0061] S4. Insert the drive rod 61 into the first embedded strip 1 until the plug rod 612 is inserted into the strip groove 54. Rotate the knob 62 to drive the drive rod 61 and the drive pulley 51 to rotate. The drive pulley 51 causes the driven gear and the double-acting screw 43 to rotate through the synchronous belt 53, thereby causing the support column 42 to drive the first spring 45 and the arc plate 44 to move until the two ends of the waterproof strip 31 abut against the first embedded strip 1 and the second embedded strip 2 respectively.

[0062] S5. Press down on the knob 62 until the knob 62 enters the rectangular groove 14. The knob 62 drives the drive rod 61 and the abutment block 63 to move, thereby causing the clamping block 16 to press the mounting plate 32 and the limiting block 71 to be inserted into the limiting hole 74.

[0063] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
