Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a position-limiting aluminum alloy double-groove guide rail. Background Art

[0002] A climbing frame, also known as a lifting frame, is a new type of scaffolding system developed in recent years, primarily used in high-rise buildings with shear walls. It can ascend or descend along a building, primarily through a connection to the building's exterior wall via wall-mounted supports and powered by an electric hoist. The wall-mounted supports are the primary load-bearing and load-transmitting components of the climbing frame, bearing and transmitting the load. Furthermore, the internal anti-fall device provides a blocking protection function in the event of an accidental fall, thereby fulfilling its load-bearing, anti-fall, and anti-overturning functions. It is a crucial safety feature of the climbing frame.

[0003] Existing wall-mounted supports, when the climbing frame's guide rails are ascending or descending, have their anti-tilt portions in direct contact with the guide rails, generating significant friction. Frictional heat during climbing, or weather changes, can cause the guide rails to expand or contract significantly. This, combined with the stresses they bear, can easily lead to cracks in the rails, shortening their service life. Furthermore, existing techniques typically place the guide rails on the climbing frame and the wall-mounted supports on the building wall. This increases the weight of the climbing frame, increasing the load on the electric hoist and potentially damaging it.

[0004] Therefore, there is a need for a limited aluminum alloy double-groove guide rail that can reduce the load of the electric hoist while extending its own service life. Summary of the Invention

If it exceeds the preset range, it is determined whether the third change value is a positive value. If so, the second solenoid valve is opened until the third change value is within the preset range; otherwise, the first solenoid valve is opened until the third change value is within the preset range.

[0018] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1 to 3 A position-limiting aluminum alloy double-groove guide rail 1 is used in conjunction with a wall-mounted support for lifting a climbing frame on a building. The position-limiting aluminum alloy double-groove guide rail 1 is arranged on the outer wall 2 of the building, and the wall-mounted support is arranged on the climbing frame; The limited aluminum alloy double-groove guide rail 1 includes a guide rail body, a heating system 3, a cooling system 4, a controller and an even number of temperature sensors 5, with each two temperature sensors 5 being distributed in pairs on the guide rail body and the outer wall 2; the temperature sensors 5, the heating system 3, and the cooling system 4 are electrically connected to the controller respectively; The guide rail body is in the shape of an elongated strip, with sliding grooves 11 provided on both sides of the guide rail body, and a temperature regulating groove 12 provided inside the guide rail body; a plurality of first pipes 13 and a plurality of second pipes 14 are provided in the temperature regulating groove 12, and the first pipes 13 and the second pipes 14 are respectively attached to the inner side walls of the temperature regulating groove 12; The heating system 3 includes a heating water tank 31, a first circulation pump 32, and a first circulation pipeline 33. The first circulation pipeline 33 passes through the temperature control tank 12. The heating water tank 31 and the first circulation pump 32 are connected to the first circulation pipeline 33. The first circulation pipeline 33 is provided with a plurality of first outlets and a plurality of first inlets. One end of the first pipeline 13 is provided with a first solenoid valve 15 and is connected to the first outlet through the first solenoid valve 15, and the other end is connected to the first inlet. The refrigeration system 4 includes a refrigeration water tank 41, a second circulation pump 42, and a second circulation pipeline 43. The second circulation pipeline 43 passes through the temperature control tank 12. The refrigeration water tank 41 and the second circulation pump 42 are connected to the second circulation pipeline 43. The second circulation pipeline 43 is provided with a plurality of second outlets and a plurality of second inlets. One end of the second pipeline 14 is provided with a second solenoid valve 16 and is connected to the second outlet through the second solenoid valve 16, and the other end is connected to the second inlet. The controller controls the first circulation pump 32 and the second circulation pump 42 to be in working state, and the first solenoid valve 15 and the second solenoid valve 16 to be in closed state; The test obtains the thermal expansion coefficient of the building's exterior wall 2 and the expansion coefficient of the guide rail body; the controller obtains the temperature value of the guide rail body when it is installed on the exterior wall 2 and sets the temperature value as a reference value, the controller obtains the temperature change of each pair of temperature sensors 5 in real time, and calculates the expansion and contraction caused by the temperature change of the exterior wall 2 using the reference value through the temperature sensor 5 set on the wall to obtain a first change value, and calculates the expansion and contraction of the track body caused by the temperature change of the track using the reference value through the temperature sensor 5 set on the track body to obtain a second change value, subtracts the second change value from the first change value to obtain a third change value, and at the same time determines whether the third change value is within a preset range. If it exceeds the preset range, it determines whether the third change value is a positive value. If so, the second solenoid valve 16 is opened until the third change value is within the preset range; otherwise, the first solenoid valve 15 is opened until the third change value is within the preset range.

[0020] From the above description, it can be seen that by exchanging the position of the existing limiting aluminum alloy double-groove guide rail 1 with the wall-mounted support, the overall weight of the climbing frame can be greatly reduced, the load of the electric hoist is reduced, and the cost is reduced and the safety is improved; and by setting the limiting aluminum alloy double-groove guide rail 1 on the outer wall 2 of the building, the contact area between the outer wall 2 and the limiting aluminum alloy double-groove guide rail 1 is made larger, avoiding the existing setting of the wall-mounted support on the outer wall 2, which causes the force to be concentrated and easily causes cracks in the outer wall 2; by setting temperature sensors 5 in pairs and combining the heating system 3 and the cooling system 4, each section of the guide rail body and the outer wall 2 can be matched one by one, and each section of the guide rail body can be heated or cooled separately, so that the expansion and contraction of each section of the guide rail body is consistent with the concrete outer wall The wall 2 expands and contracts synchronously to avoid frictional heat during climbing or weather changes that may cause the guide rail to expand or contract seriously, reduce or avoid cracks in the track, and ensure the service life of the guide rail; and through temperature control, the volume change is controlled, and the guide rail body and the wall-mounted support can be matched with lower precision, thereby achieving lower manufacturing and construction costs, avoiding the high cost problem caused by the need to ensure the accuracy of matching in order to avoid excessive frictional heat in the existing technology; at the same time, once the climbing frame falls, the force is applied to the entire guide rail body and then transmitted to the entire outer wall 2 in contact without cracking, avoiding the traditional wall-mounted support force that easily causes the local outer wall 2 to be overstressed and cracked; it can also reduce the instability of the climbing frame operation due to thermal expansion and contraction.

[0021] Furthermore, the guide rail body includes multiple sections of sub-guide rails 17, and each section of the sub-guide rail 17 corresponds to a pair of temperature sensors 5; The first circulation pipeline 33 and the second circulation pipeline 43 are both multi-section structures and are respectively arranged in each section of the sub-guide rail 17, and the head and tail of each section are respectively provided with a quick connector and a matching quick connector slot; A section of the first pipeline 13 and a section of the second pipeline 14 are provided in each section of the sub-guide rail 17 .

[0022] From the above description, it can be seen that by dividing the sub-guide rail 17 into multiple sections and corresponding to a pair of temperature sensors 5, accurate control of each section of the sub-guide rail 17 can be achieved; at the same time, the first circulation pipeline 33 and the second circulation pipeline 43 are both multi-section structures, and the head and tail of each section structure are respectively provided with quick connectors and matching quick connector slots, which can achieve quick disassembly and quick assembly to meet the disassembly and assembly requirements.

[0023] Furthermore, before the climbing frame is climbed, part of the sub-guide rail 17 is connected to the top or bottom of the sub-guide rail 17 on the fixed outer wall 2 to form a connection; When the climbing frame climbs up or descends, it continues to crawl along the continued sub-guide rail 17, and the exposed sub-guide rail 17 is removed for continued use.

[0024] As can be seen from the above description, by using the sub-guide rails 17 in succession, it is only necessary to prepare the number of rails as required, without having to arrange them on the entire exterior wall surface 2, thereby reducing costs and construction difficulty.

[0025] Furthermore, a plurality of fixing holes 18 are provided at the bottom of the temperature regulating groove 12 of the guide rail body; The side of the guide rail body facing the outer wall 2 is a rough surface; The position-limiting aluminum alloy double-groove guide rail 1 further includes expansion bolts, which fasten the guide rail body to the outer wall surface 2 through the fixing holes 18 .

[0026] From the above description, it can be seen that by making the side of the guide rail body facing the outer wall 2 a rough surface and fastening the guide rail body to the outer wall 2 through the fixing hole 18 with expansion bolts, the friction between the outer wall 2 and the guide rail body can be increased, ensuring the force effect when the climbing frame is in use, and at the same time reducing or avoiding the problem of cracks or even ruptures in the outer wall caused by insufficient force area.

[0027] Furthermore, a plurality of force-bearing grooves 19 cooperating with the wall-mounted supports are provided on one surface of the guide rail body facing the wall-mounted supports; The intervals between the plurality of stress-bearing grooves 19 are fixed intervals, and the intervals between the plurality of fixing holes 18 are integer multiples of the intervals between the stress-bearing grooves 19 .

[0028] From the above description, it can be seen that through integer multiples, each fixing hole 18 can be aligned with one of the stress grooves 19, which is convenient for installation; the stress groove 19 is used for climbing, descending or preventing the wall-mounted support from falling, which is the same function as in the prior art.

[0029] Furthermore, when the thermal expansion coefficient of the building exterior wall 2 is obtained through testing, the thermal expansion coefficient of the building exterior wall 2 is retested when the distance in the vertical direction exceeds a preset value.

[0030] From the above description, it can be seen that due to the different load-bearing requirements of buildings at different heights, different cement mortar grades are used, so the expansion coefficient will change, for example, it needs to be recalibrated every 15m.

[0031] Furthermore, the guide rail body is made of aluminum alloy.

[0032] As can be seen from the above description, by adopting aluminum alloy, a lower weight and softer guide rail body can be achieved, so that when the guide rail body contacts the outer wall surface 2, a larger contact area can be obtained through tightening.

[0033] Furthermore, the surfaces of the first circulation pipeline 33 and the second circulation pipeline 43 are covered with a thermal insulation layer 6 .

[0034] As can be seen from the above description, by providing the thermal insulation layer 6 , the thermal insulation of the first circulation pipeline 33 and the second circulation pipeline 43 can be achieved while avoiding interference with the guide rail body that does not require adjustment.

[0035] Furthermore, the position-limiting aluminum alloy double-groove guide rail 1 also includes a monitoring end, which is electrically connected to a controller, and the controller transmits information from the temperature sensor 5 to the monitoring end.

[0036] From the above description, it can be seen that the temperature of the track body and the outer wall 2 can be monitored in real time through the monitoring terminal.

[0037] Furthermore, the monitoring terminal uploads the acquired temperature sensor 5 data to the blockchain for storage and / or uploads it to the regulatory agency for storage.

[0038] From the above description, it can be seen that by uploading the information of the temperature sensor 5 to the blockchain for storage and / or uploading it to the regulatory agency for storage, it can be prevented from being tampered with, ensuring that the construction information can be checked and remotely monitored.
