Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to an energy-saving and environment-friendly building thermal insulation structure. Background Art

[0002] The building thermal insulation structure is an important part of the building envelope system, and its design and construction directly affect the energy-saving performance, durability and comfort of the building; among various forms of building thermal insulation structures, thermal insulation boards are widely used due to their good thermal insulation performance, construction convenience and other advantages.

[0003] The installation process of the thermal insulation board is relatively standardized and delicate, specifically covering multiple key steps: base treatment, setting out and snapping lines, preparation and application of the adhesive, cutting and arranging of the thermal insulation board, pasting of the thermal insulation board and fixing of the anchor fittings, etc. Among them, in the process of fixing the thermal insulation board with anchor fittings, first use professional drilling equipment to drill holes on the surface of the thermal insulation board and the wall according to the predetermined positions, then accurately place the anchor fittings, such as expansion sleeves, into the drilled holes, then put the screws into the expansion sleeves, and then moderately tighten the screws through tools such as wrenches, so that the expansion part of the expansion sleeve expands fully in the hole and tightly embeds into the wall body.

[0004] However, there are also some problems in the installation process of the existing thermal insulation boards: in the link of fixing the thermal insulation board with anchor fittings, the traditional installation method requires a series of operations such as drilling holes, putting the expansion sleeves into the holes, putting the screws into the expansion sleeves, and turning the screws in strict accordance with the procedures. The steps are complicated and time-consuming, which not only increases the labor intensity and construction difficulty of the construction workers, but also extends the overall construction period to a certain extent and increases the construction cost; in addition, due to the large number of operation steps, in the actual construction process, once an improper operation occurs in a certain link, such as the expansion sleeve is not fully placed into the hole, the screw is not fully tightened, etc., it may affect the connection strength between the thermal insulation board and the wall, and then affect the overall performance of the thermal insulation structure. Summary of the Invention

[0005] Based on this, it is necessary to provide an energy-saving and environment-friendly building thermal insulation structure aiming at the problem of low installation efficiency existing in the installation process of the current thermal insulation board.

[0009] Further, the energy-saving and environment-friendly building insulation structure further includes a connecting mechanism configured to connect at least three adjacent insulation boards together.

[0010] Further, the connecting mechanism includes a rotating sleeve, a one-way component, two first racks and a plurality of tooth protrusions. The rotating sleeve is sleeved on the base cylinder and can rotate around its own axis; the plurality of tooth protrusions are arranged on the outer peripheral wall of the rotating sleeve and are arranged at equal intervals circumferentially; the first rack extends in the horizontal direction and can form a sliding fit with the insulation board. The two first racks are inserted into the insulation board in parallel and are respectively located on both sides of the rotating sleeve and are both engaged with the tooth protrusions; under the action of the one-way component, the rotating sleeve can rotate unidirectionally along with the base cylinder.

[0011] Further, the connecting mechanism includes a rotating sleeve, a one-way component, two second racks and a plurality of tooth protrusions. The rotating sleeve is sleeved on the base cylinder and can rotate around its own axis; the plurality of tooth protrusions are arranged on the outer peripheral wall of the rotating sleeve and are arranged at equal intervals circumferentially; the second rack extends in the vertical direction and can form a sliding fit with the insulation board. The two second racks are inserted into the insulation board in parallel and are respectively located on both sides of the rotating sleeve and are both engaged with the tooth protrusions; under the action of the one-way component, the rotating sleeve can rotate unidirectionally along with the base cylinder.

[0012] Further, the one-way component includes a first ratchet tooth and a plurality of second ratchet teeth. The first ratchet tooth is arranged on the outer peripheral wall of the base cylinder; the plurality of second ratchet teeth are arranged on the inner peripheral wall of the rotating sleeve, are arranged circumferentially, and can form a one-way fit with the first ratchet tooth.

[0014] Further, the number of the first sliding grooves and the number of the sliding convexes are both multiple, and they are arranged circumferentially respectively.

[0015] Further, the pressing part is of an annular structure.

[0016] Further, a plurality of pressure increasing holes are provided on the end surface of the pressing part, and the plurality of pressure increasing holes are arranged circumferentially.

[0017] Further, the pressure increasing hole is of a linear structure, with one end large and the other end small.

[0018] The beneficial effects of the present invention are as follows:

[0019] During the use of the energy-saving and environment-friendly building thermal insulation structure provided by the present invention, first, the thermal insulation board is attached to the wall, and under the support of the wall, the thermal insulation board synchronously compresses the screw drill bit; then the twist drill bit is inserted into the anchor and abuts against the wall, and then the wall is drilled through the twist drill bit; when a hole appears in the wall, the screw drill bit is inserted into the hole under its own elastic action, and then contracts inward under the extrusion of the inner side wall of the hole, so that the twist drill bit synchronously drives the screw drill bit to rotate forward. The screw drill bit pre-cuts a thread groove at the inner side wall of the hole while drilling into the hole by cutting the side wall with a smaller slope of the cutting and guiding hole, which not only reduces the influence on the drilling of the twist drill bit but also reduces the difficulty of cutting the thread groove at the inner side wall of the hole subsequently; at the same time, the twist drill bit synchronously drives the screw drill bit to stretch, and then drives the pressing part to approach the thermal insulation board through the screw drill bit; when the preset drilling time is reached, the twist drill bit is driven to rotate reversely, the twist drill bit synchronously drives the screw drill bit to rotate reversely, and a thread groove is cut at the inner side wall of the hole by the side wall with a larger slope of the cutting and guiding hole; then the process of the forward and reverse rotation of the twist drill bit is repeated until the drilling is in place. At this time, the pressing part presses on the surface of the thermal insulation board; then the twist drill bit is pulled out, the screw drill bit resets under its own elastic action, and clamps the thread groove to realize the fixation of the thermal insulation board, so that the drilling and the installation of the anchor can be carried out simultaneously, which can not only simplify the installation steps but also improve the installation efficiency.

[0020] Further, by providing a connecting mechanism, during the use process, at least three adjacent thermal insulation boards are connected together, which helps to improve the overall structural stability of the thermal insulation boards. Description of the Drawings

[0041] Such as Figures 1 to 11As shown in the figure, the energy-saving and environment-friendly building thermal insulation structure provided by the embodiment of the present invention is set to include a thermal insulation board 1 and an anchor 2. When the thermal insulation board 1 is installed, it is connected to the wall through the anchor 2. Among them, the anchor 2 includes a base cylinder 201, a pressing part 202 and a threaded drill bit 203. The pressing part 202 and the threaded drill bit 203 are respectively arranged at both ends of the base cylinder 201. The pressing part 202 can form a stop fit with the thermal insulation board 1. The threaded drill bit 203 is elastic and has a conical structure. The threaded drill bit 203 includes a threaded drill ring 2031, a guiding ring 2032 and a clamping ring 2033. The large end of the threaded drill ring 2031 is fixedly sleeved on the base cylinder 201. The circumferential side wall of the threaded drill ring 2031 is a threaded structure. The threaded drill ring 2031 can expand and contract along its own axis direction. A plurality of cutting and material guiding holes 20311 are arranged on the circumferential side wall of the threaded drill ring 2031. The plurality of cutting and material guiding holes 20311 are arranged circumferentially. The side wall of the cutting and material guiding hole 20311 is inclined. And the slope of one side wall of the cutting and material guiding hole 20311 is greater than that of the other side wall. The guiding ring 2032 is inserted into the threaded drill ring 2031. The small end of the guiding ring 2032 is fixedly arranged at the small end of the threaded drill ring 2031. The large end of the guiding ring 2032 is suspended. The clamping ring 2033 is inserted into the guiding ring 2032 and can both move axially relative to the guiding ring 2032 and synchronously drive the guiding ring 2032 to rotate around its own axis.

[0042] Specifically in this embodiment, when the base cylinder 201 is installed, its axis is perpendicular to the plate surface of the thermal insulation board 1 and is inserted through the thermal insulation board 1. The pressing part 202 is located on the side of the base cylinder 201 away from the thermal insulation board 1. The threaded drill bit 203 is located on the side of the base cylinder 201 close to the thermal insulation board 1. The threaded drill ring 2031, the guiding ring 2032 and the clamping ring 2033 are all of conical structures, and the small ends of the threaded drill ring 2031, the guiding ring 2032 and the clamping ring 2033 all face the thermal insulation board 1. The cutting and material guiding hole 20311 is of a strip structure and extends along the generatrix direction of the threaded drill ring 2031.

[0043] Optionally, an electric drill 5 can be used to drive the twist drill bit 4 to rotate.

[0044] During use, first, the heat preservation board 1 is attached to the wall surface. At this time, due to the wall forming a reverse thrust on the threaded drill bit 203, the elastic threaded drill bit 203 is compressed and deformed under extrusion; then, a suitable twist drill bit 4 is selected and fixed through a drill 5, and then the twist drill bit 4 is passed through the pressing part 202, the base cylinder 201, and the threaded drill bit 203 in sequence, so that the end of the twist drill bit 4 abuts against the wall surface; then the drill 5 is started, and the drill 5 drives the twist drill bit 4 to rotate forward to drill the wall; during the process of the twist drill bit 4 rotating and drilling into the wall, as the wall is gradually drilled out with a hole, the originally compressed threaded drill bit 203 will automatically insert into the hole under the action of its own elastic restoring force.

[0045] When the threaded drill bit 203 is inserted into the hole, due to the radial extrusion of the inner wall of the hole on the threaded drill bit 203, the threaded drill ring 2031 will contract inward; during the contraction of the threaded drill ring 2031, its inner wall is in close contact with the outer wall of the guiding ring 2032 and produces an extrusion effect, thereby pushing the guiding ring 2032 to contract inward; during the contraction of the guiding ring 2032, its inner wall is in close contact with the outer wall of the clamping ring 2033 and produces an extrusion effect, thereby pushing the clamping ring 2033 to contract inward. The clamping ring 2033 contracts and clamps the twist drill bit 4, so that the twist drill bit 4 synchronously drives the threaded drill bit 203 to rotate forward.

[0046] During the process of the twist drill bit 4 drilling, the impurities cut by the threaded drill bit 203 can pass through the cutting material guiding holes 20311 and the twist drill bit 4 in sequence and be discharged, so as to reduce the influence on the drilling efficiency of the twist drill bit 4 and the threaded drill bit 203 caused by the accumulation of impurities in the hole.

[0047] During the process of the threaded drill bit 203 rotating forward, the threaded drill bit 203 pre-cuts a thread groove at the inner wall of the hole through the side wall with a smaller slope of the cutting material guiding hole 20311 while penetrating into the hole, which not only reduces the influence on the drilling of the twist drill bit 4 but also reduces the difficulty of cutting the thread groove at the inner wall of the hole subsequently; since the twist drill bit 4 drills actively while the threaded drill bit 203 drills passively, the drilling speed of the twist drill bit 4 is greater than that of the threaded drill bit 203. The twist drill bit 4 synchronously drives the clamping ring 2033 to continuously move deeper into the hole relative to the guiding ring 2032; as the clamping ring 2033 moves, the conical structure of the guiding ring 2032 gradually strengthens the radial constraint on the clamping ring 2033, making the clamping ring 2033 further shrink, thereby increasing the clamping force on the twist drill bit 4. Under the action of this increased clamping force, the twist drill bit 4 can more stably and efficiently synchronously drive the threaded drill bit 203 to stretch. The axial tension generated by the threaded drill bit 203 during stretching is transmitted to the pressing part 202 through the base cylinder 201, thereby driving the pressing part 202 to gradually approach the surface of the heat preservation board 1.

[0048] After drilling for a preset time, the electric drill 5 drives the twist drill bit 4 to rotate in the opposite direction, and the twist drill bit 4 drives the threaded drill bit 203 to rotate in the opposite direction synchronously; at this time, the other side wall of the material guide hole 20311 with a larger slope on the threaded drill ring 2031 performs deep cutting on the inner wall of the hole, and gradually processes the pre-cut thread groove profile into a complete thread groove. Thereafter, the operation process of the twist drill bit 4 rotating forward and reverse is repeated, and each forward and reverse rotation further deepens and improves the processing of the thread groove. Until the drilling depth reaches the preset depth, the pressing part 202 presses on the surface of the insulation board 1.

[0049] Finally, the twist drill bit 4 is pulled out from the pressing portion 202, the base tube 201 and the threaded drill bit 203. In the process of pulling out the twist drill bit 4, since the twist drill bit 4 drives the clamping ring 2033 to approach the large end of the guide ring 2032, the clamping force of the clamping ring 2033 on the twist drill bit 4 is gradually reduced, so that the twist drill bit 4 can be more easily separated from the clamping ring 2033, avoiding the twist drill bit 4 driving the threaded drill bit 203 to move, resulting in damage to the formed thread groove. Subsequently, the threaded drill bit 203 is quickly reset under the action of its own elastic restoring force, and the thread structure on the threaded drill ring 2031 is tightly embedded in the processed thread groove, forming a firm mechanical bite connection, thereby achieving reliable fixation of the insulation board 1.

[0050] Through the above method, multiple independent operation steps in the traditional installation process, such as wall drilling, inserting anchor 2, rotating anchor 2, etc., are organically integrated and completed at one time, which greatly simplifies the installation process of the insulation board 1 and significantly improves the installation efficiency. At the same time, it effectively reduces the labor intensity and construction cost of construction workers and ensures the overall performance and stability of the insulation structure.

[0051] In some embodiments, the building insulation structure configured to be energy-saving and environmentally friendly also includes a connecting mechanism, and the connecting mechanism is configured to connect at least three adjacent insulation boards 1 together. In this way, during the installation process, at least three adjacent insulation boards 1 can be connected together through the connecting mechanism, so that each insulation board 1 can support each other and cooperate with each other. Then, when facing external environmental factors, such as wind force, thermal expansion and contraction caused by temperature changes, the force borne by a single insulation board 1 can be evenly dispersed to adjacent insulation boards 1 through the connecting mechanism, avoiding the displacement, deformation or even falling off of a single insulation board 1 due to concentrated force. At the same time, the integrated insulation boards 1 form a continuous and stable insulation layer on the wall surface, which enhances the overall covering effect of the insulation structure on the wall, and further improves the energy-saving performance, durability and comfort of the building.

[0052] Further, to facilitate the connection of at least three adjacent insulation boards 1 arranged horizontally, the connecting mechanism is configured to include a rotating sleeve 301, a one-way component 302, two first racks 303, and multiple tooth protrusions 304. The rotating sleeve 301 is sleeved on the base cylinder 201 and can rotate around its own axis; the multiple tooth protrusions 304 are arranged on the outer peripheral wall of the rotating sleeve 301 and are arranged at equal intervals in the circumferential direction; the first racks 303 extend horizontally and can form a sliding fit with the insulation board 1. The two first racks 303 are inserted into the insulation board 1 in parallel and are respectively located on both sides of the rotating sleeve 301 and are both engaged with the tooth protrusions 304; under the action of the one-way component 302, the rotating sleeve 301 can rotate unidirectionally with the base cylinder 201.

[0053] Specifically, to facilitate the installation of the first racks 303 and reduce the impact on the performance of the insulation board 1, two second chutes are provided on the surface of the insulation board 1 facing the wall. The second chutes extend horizontally, and the two second chutes are arranged at intervals in the vertical direction and are respectively located above and below the anchor 2. When installing, the two first racks 303 are respectively slidably inserted into the two second chutes. The second chutes at the same horizontal height on adjacent insulation boards 1 are interconnected to ensure that the first racks 303 can move to other insulation boards 1.

[0054] Optionally, the length of the first rack 303 can be set to be equal to the length of the insulation board 1.

[0055] During use, when the twist drill 4 drives the threaded drill 203 to rotate forward, the threaded drill 203 synchronously drives the base cylinder 201 to rotate forward. At this time, the base cylinder 201 synchronously drives the rotating sleeve 301 to rotate through the one-way component 302. The rotating sleeve 301 drives the two first racks 303 to move away from each other along the second chutes through the tooth protrusions 304, so that the two first racks 303 can respectively move to the two insulation boards 1 adjacent to the current insulation board 1 on the left and right, thereby being able to connect the three adjacent insulation boards 1 on the left and right together; when the twist drill 4 drives the threaded drill 203 to rotate backward, under the action of the one-way component 302, the rotating sleeve 301 will not rotate, thus avoiding driving the two first racks 303 to approach each other.

[0056] It can be understood that by selecting the first racks 303 with a longer length, the two first racks 303 can respectively move to multiple insulation boards 1 adjacent to the current insulation board 1 on the left and right, thereby being able to connect multiple adjacent horizontally arranged insulation boards 1 together.

[0057] In other embodiments, to facilitate the connection of at least three adjacent thermal insulation boards 1 arranged in the vertical direction, the connection mechanism is arranged to include a rotating sleeve 301, a one-way component 302, two second racks, and a plurality of tooth protrusions 304. The rotating sleeve 301 is sleeved on the base cylinder 201 and can rotate around its own axis; the plurality of tooth protrusions 304 are arranged on the outer peripheral wall of the rotating sleeve 301 and are arranged at equal intervals in the circumferential direction; the second racks extend in the vertical direction and can form a sliding fit with the thermal insulation board 1. The two second racks are inserted into the thermal insulation board 1 in parallel and are respectively located on both sides of the rotating sleeve 301 and are both engaged with the tooth protrusions 304; under the action of the one-way component 302, the rotating sleeve 301 can rotate unidirectionally along with the base cylinder 201.

[0058] Specifically, to facilitate the installation of the second racks and reduce the impact on the performance of the thermal insulation board 1, two third chutes are provided on the surface of the thermal insulation board 1 facing the wall. The third chutes extend in the vertical direction, and the two third chutes are arranged at intervals in the horizontal direction and are respectively located on the left and right sides of the anchor 2. When installing, the two second racks are respectively slidably inserted into the two third chutes. The third chutes at the same horizontal height on adjacent thermal insulation boards 1 are interconnected to ensure that the second racks can move to other thermal insulation boards 1.

[0059] Optionally, the length of the second rack can be set to be equal to the length of the thermal insulation board 1.

[0060] During use, when the twist drill 4 drives the threaded drill 203 to rotate forward, the threaded drill 203 synchronously drives the base cylinder 201 to rotate forward. At this time, the base cylinder 201 synchronously drives the rotating sleeve 301 to rotate through the one-way component 302. The rotating sleeve 301 drives the two second racks to move away from each other along the third chutes through the tooth protrusions 304, so that the two second racks can respectively move to the two thermal insulation boards 1 adjacent to the current thermal insulation board 1 above and below, so as to be able to connect the three adjacent thermal insulation boards 1 above and below together; when the twist drill 4 drives the threaded drill 203 to rotate backward, under the action of the one-way component 302, the rotating sleeve 301 will not rotate, thus avoiding driving the two second racks to approach each other.

[0061] It can be understood that by selecting second racks with a longer length, the two second racks can respectively move to a plurality of thermal insulation boards 1 adjacent to the current thermal insulation board 1 above and below, so as to be able to connect a plurality of adjacent thermal insulation boards 1 arranged in the vertical direction together.

[0062] In other embodiments, to facilitate connecting at least three adjacent thermal insulation boards 1 arranged vertically and at least three adjacent thermal insulation boards 1 arranged vertically at the same time, when the connecting mechanism is set to include a rotating sleeve 301, a one-way component 302, two first racks 303, two second racks, and multiple tooth protrusions 304, to avoid interference, the first rack 303 and the second rack are arranged staggered in a direction perpendicular to the plate surface of the thermal insulation board 1.

[0063] In some other embodiments, the one-way component 302 is set to include a first ratchet tooth 3021 and multiple second ratchet teeth 3022. The first ratchet tooth 3021 is arranged on the outer peripheral wall of the base cylinder 201; the multiple second ratchet teeth 3022 are arranged on the inner peripheral wall of the rotating sleeve 301 and are arranged circumferentially, and can form a one-way fit with the first ratchet tooth 3021.

[0064] Specifically in this embodiment, as Figure 11 shown, when the base cylinder 201 rotates counterclockwise, the first ratchet tooth 3021 and the second ratchet tooth 3022 are engaged, so that the base cylinder 201 can drive the rotating sleeve 301 to rotate synchronously; when the base cylinder 201 rotates clockwise, the first ratchet tooth 3021 and the second ratchet tooth 3022 form a sliding fit, so that the base cylinder 201 cannot drive the rotating sleeve 301 to rotate.

[0065] In some other embodiments, a first sliding groove is arranged on the inner peripheral wall of the guiding ring 2032, and the first sliding groove extends along the axial direction of the guiding ring 2032; a sliding protrusion is arranged on the outer peripheral wall of the clamping ring 2033, and the sliding protrusion is inserted into the first sliding groove and can slide along the first sliding groove. In this way, through the sliding fit between the sliding protrusion and the first sliding groove, the clamping ring 2033 can not only move axially relative to the guiding ring 2032, but also drive the guiding ring 2032 to rotate around its own axis synchronously.

[0066] In a further embodiment, to further improve the stability, reliability of the movement between the guiding ring 2032 and the clamping ring 2033, and the efficiency of power transmission, the number of the first sliding grooves and the number of the sliding protrusions are both multiple, and they are arranged circumferentially respectively.

[0067] Specifically in this embodiment, the number of the first sliding grooves can be set to three and are arranged evenly circumferentially; the number of the sliding protrusions is correspondingly set to three and are arranged evenly circumferentially. This circumferential uniform distribution method has many advantages: from a mechanical perspective, three evenly distributed first sliding grooves and sliding protrusions can disperse the external force borne by the clamping ring 2033 more evenly to the guiding ring 2032, avoiding structural damage or movement jamming caused by excessive local stress; in terms of power transmission, multiple contact points can transmit torque more effectively, ensuring that the clamping ring 2033 rotates the guiding ring 2032 more smoothly and efficiently.

[0068] In some other embodiments, the pressing part 202 is arranged as an annular structure. In this way, when the pressing part 202 contacts the heat preservation board 1, the annular structure enables the pressing part 202 to provide a uniform pressure distribution, ensuring that the heat preservation board 1 is evenly stressed during the fixing process and avoiding installation defects caused by excessive or too small local pressure.

[0069] In a further embodiment, a plurality of pressure increasing holes 2021 are arranged on the end surface of the pressing part 202, and the plurality of pressure increasing holes 2021 are arranged along the circumferential direction. In this way, when the contact pressure between the pressing part 202 and the heat preservation board 1 remains unchanged, the arrangement of the pressure increasing holes 2021 can reduce the contact area between the pressing part 202 and the heat preservation board 1. According to the pressure formula P = F / S, on the premise that the pressure F remains unchanged, when the stressed area S decreases, the pressure acting on the surface of the heat preservation board 1 by the pressing part 202 will increase. The increased pressure can make the pressing part 202 fit more closely to the heat preservation board 1, effectively reducing the possible tiny gaps between the two, and improving the tightness of the connection. At the same time, this tight fit helps to enhance the fixing effect of the anchor 2 on the heat preservation board 1, enabling the heat preservation board 1 to be more firmly held on the wall when subjected to external forces such as wind force and temperature stress, reducing the risks of displacement and shedding of the heat preservation board 1, and further improving the overall stability and reliability of the building heat preservation structure, and ensuring the energy-saving, durability and comfort performance of the building.

[0070] Specifically in this embodiment, the number of the pressure increasing holes 2021 can be set to ten, and the ten pressure increasing holes 2021 are evenly arranged along the circumferential direction.

[0071] In a further embodiment, the pressure increasing hole 2021 is arranged as a linear structure with one end large and the other end small. In this way, when the larger end bears the external pressure, it can more efficiently collect and guide the pressure, while the smaller end can concentrate the pressure and accurately act on the surface of the heat preservation board 1, realizing effective pressure increase and accurate pressure transmission; through this structural design, when using the anchor 2 to fix the heat preservation board 1, the pressure can be better utilized, enhancing the fit degree and connection strength between the pressing part 202 and the heat preservation board 1, thereby improving the stability and reliability of the entire building heat preservation structure.

[0072] Optionally, the pressure increasing hole 2021 can be set with a small inner end and a large outer end.

[0073] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope recorded in this specification.

[0074] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
