Abstract
Description
Technical Field
[0001] The invention relates to a wall bushing, in particular to an assembled steel structure ultra-low energy consumption building wall bushing and a use method thereof. Background Art
[0002] Prefabricated steel structure ultra-low energy consumption buildings are an important development direction of current buildings due to their advantages such as environmental protection and energy saving. For ultra-low energy consumption buildings, how to ensure airtightness is a key technology that needs to be overcome urgently, especially for the connection parts of the external protective panels, the connection parts between the external protective panels and the main structure, the connection parts between the external doors and windows and the external protective walls, the connection parts before and after the sealing of the external wall construction openings, and the parts of the external wall casing, which are the hot spots and difficulties in the current research of ultra-low energy consumption buildings. For wall casings, which are used to connect cables or air-conditioning pipelines, the current focus is basically on the airtightness between the casing and the wall, and certain results have been achieved. However, for the wall casing itself, since it is a through-pipe structure, the airtightness problem in the pipeline has been ignored.
[0003] For prefabricated steel structure ultra-low energy consumption buildings, it is necessary to avoid opening through-wall holes on site later, so it is necessary to reserve the through-wall sleeve in the wall during wall construction. When the reserved through-wall sleeve is not used, the inside of the sleeve is sealed with a sealant or sealing material to ensure the air tightness of the through-wall sleeve; however, when the through-wall sleeve is used for threading, other pipelines such as the connecting pipeline or cable between the outdoor unit and the indoor unit of the air conditioner pass through the through-wall sleeve, and a gap will be formed between the pipeline and the inner wall of the through-wall sleeve, resulting in air leakage at the through-wall sleeve. The current construction method is generally to fill the gap between the inner wall of the through-wall sleeve and the pipeline with sealing material after the pipeline passes through the through-wall sleeve to seal the through-wall sleeve. However, this sealing method cannot ensure dense filling on the one hand, and if the pipeline moves, the joint surface between the pipeline and the sealing material will be destroyed, resulting in poor sealing; on the other hand, when replacing or repairing the pipeline in the later stage, the sealing material in the through-wall sleeve needs to be broken, which is difficult to operate and easy to damage the pipeline. Summary of the invention
[0004] The purpose of the present invention is to provide a prefabricated steel structure ultra-low energy consumption building wall sleeve and a use method to solve the problem that the gap between the existing pipeline and the wall sleeve is difficult to seal tightly and is not conducive to later replacement and maintenance.
[0005] The present invention is achieved as follows: an assembled steel structure ultra-low energy consumption building wall sleeve, including a sleeve that penetrates the wall, in which a first elastic clip, a flexible thermal insulation piece and a second elastic clip are arranged in sequence along the axial direction of the sleeve, and an insertion hole along the axial direction of the sleeve is opened on the flexible thermal insulation piece, the outer surface of the flexible thermal insulation piece is in contact with the inner wall of the sleeve, the first elastic clip and the second elastic clip both include a circle of elastic petals, the elastic petals are inclined along the axial direction of the sleeve, and the inclination direction of the elastic petals of the first elastic clip and the elastic petals of the second elastic clip are the same, one end of the flexible thermal insulation piece is conical and the other end is trumpet-shaped, and the two ends of the flexible thermal insulation piece are respectively in contact with the elastic petals of the first elastic clip and the elastic petals of the second elastic clip.
[0006] A limiting boss is provided at one end of the inner wall of the sleeve, and an internal thread is provided at the other end; one of the first elastic clamp and the second elastic clamp contacts the limiting boss, and the other is connected to the internal thread via an external thread.
[0007] The first elastic clamp and the second elastic clamp comprise a main body ring, and the elastic petal body is located on the inner side surface of one end of the main body ring.
[0008] The first elastic clamp is located at the outer port of the sleeve, and the second elastic clamp is located at the inner port of the sleeve. The inclination direction of the elastic petals of the first elastic clamp and the second elastic clamp is consistent with the insertion direction of the pipeline.
[0009] Also included is a blocking block disposed in the sleeve.
[0010] An end ring rib is arranged on the outer wall of the end of the sleeve.
[0011] The invention also discloses a method for using the above-mentioned assembled steel structure ultra-low energy consumption building wall sleeve, which comprises the following steps.
[0012] a. During wall construction, a sleeve is set inside the wall, and the sleeve passes through the wall.
[0013] b. Place the first elastic clamp and the flexible heat-insulating member in sequence inside the sleeve from the end with the internal thread.
[0014] c. Screw the external thread of the second elastic member onto the internal thread of the end of the sleeve so that the elastic petal of the second elastic member is located in the sleeve and contacts the flexible insulation member.
[0015] d. A blocking block is arranged in the second elastic member to seal the end of the sleeve.
[0016] e. When it is necessary to pass the pipeline, remove the block and pass the sleeve from one end of the second elastic member to the other end.
[0017] Furthermore, a sleeve is arranged according to the pipeline insertion direction so that one end of the internal thread of the sleeve is located at the insertion end of the pipeline.
[0018] The wall-penetrating sleeve of the ultra-low energy consumption building of the present invention is reserved in the wall when the assembled steel structure ultra-low energy consumption building is constructed.
[0019] When the pipeline is not inserted, the diameter of the insertion hole of the flexible thermal insulation component and the diameter of the center hole surrounded by the elastic petals of the first elastic clamp and the second elastic clamp are smaller than the diameter of the pipeline. When the pipeline is inserted, the pipeline passes through the insertion hole of the flexible thermal insulation component and the center of the first elastic clamp and the second elastic clamp, and the pipeline opens the insertion hole, the elastic petals of the first elastic clamp and the elastic petals of the second elastic clamp, and the outer side of the flexible thermal insulation component is in close contact with the inner wall of the sleeve, and the flexible thermal insulation component tightly wraps the pipeline under the elastic action. At the same time, since one end of the flexible thermal insulation component is conical, this part is tightly pressed on the outer wall of the pipeline under the action of the restoring force generated by the elastic deformation of the elastic petals; the other end of the flexible thermal insulation component is trumpet-shaped, and the opened elastic petals are pressed on the material of this part of the flexible thermal insulation component, so that the end material of the flexible thermal insulation component is tightly pressed on the inner wall of the sleeve. The first elastic clip and the second elastic clip can ensure that one end of the flexible insulation component forms a tight fitting surface with the outer wall of the pipeline, and the other end forms a tight fitting surface with the inner wall of the sleeve, so that the flexible insulation component forms a barrier inside the wall sleeve, thereby ensuring the air tightness inside the wall sleeve.
[0020] For the situation where multiple pipelines pass through the casing at the same time, such as the copper tube, condenser and power cord connecting the indoor and outdoor units of the air conditioner, the copper tube, condenser and power cord are first wrapped and wrapped together when connecting. The contour of the pipeline wrapped together is irregular. At the tapered end of the flexible thermal insulation component, under the pressure of the elastic petal body, the flexible thermal insulation component can fit tightly with the irregular contour of the pipeline, thereby ensuring air tightness.
[0021] When the pipeline needs to be replaced or repaired, the pipeline can be pulled out without damaging the components, and the present invention can continue to be used after the pipeline is replaced or repaired.
[0022] The invention is easy to use, can effectively ensure the air tightness in the wall sleeve, is convenient for replacement or maintenance of pipelines, and can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1 As shown, the present invention comprises a sleeve 2 penetrating a wall 1, and a first elastic clamp 4, a flexible heat-insulating member 3 and a second elastic clamp 5 are sequentially arranged in the sleeve 2 along the axial direction thereof.
[0028] In the present invention, the sleeve 2 is reserved in the wall 1 during the construction of the wall 1. The sleeve 2 runs through the entire wall 1. After the construction of the wall 1 is completed, the pipeline 9 is passed through the sleeve 2, and the pipeline 9 passes through the first elastic clip 4, the flexible insulation part 3 and the second elastic clip 5.
[0029] The flexible thermal insulation member 3 is made of a thermal insulation material with certain flexibility, such as diene polymer, high foam polyethylene material, etc., which can undergo certain deformation and has certain elasticity. The flexible thermal insulation member 3 is cylindrical and has a certain length. The flexible thermal insulation member 3 is located in the sleeve 2, and the outer side surface of the flexible thermal insulation member 3 is attached to the inner wall of the sleeve 2 to form a long contact surface. The flexible thermal insulation member 3 is provided with an insertion hole 3-1, and the axis of the insertion hole 3-1 coincides with the axis of the flexible thermal insulation member 3.
[0030] The first elastic clamp 4 and the second elastic clamp 5 are respectively located on both sides of the flexible thermal insulation part 3, and are respectively in contact with the ends of the flexible thermal insulation part 3. One end of the flexible thermal insulation part 3 is conical and the other end is flared, and the flexible thermal insulation part 3. The first elastic clamp 4 and the second elastic clamp 5 both include a circle of elastic petals 8, and the elastic petals 8 are inclined along the axial direction of the sleeve 2, and the inclination direction of the elastic petals 8 of the first elastic clamp 4 and the elastic petals 8 of the second elastic clamp 5 are the same. The two ends of the flexible thermal insulation part 3 are respectively in contact with the elastic petals 8 of the first elastic clamp 4 and the elastic petals 8 of the second elastic clamp 5, and the inclined end faces of the ends of the flexible thermal insulation part 3 are in contact with the inclined elastic petals 8.
[0031] Specifically, the first elastic clamp 4 is located at the outer port of the sleeve 2, the second elastic clamp 5 is located at the inner port of the sleeve 2, and the inclination direction of the elastic petal body 8 of the first elastic clamp 4 and the elastic petal body 8 of the second elastic clamp 5 is consistent with the insertion direction of the pipeline 9.
[0032] like Figure 1 , Figure 2As shown, at this time, the pipeline 9 is connected from the inside to the outside of the wall 1, so the elastic petal body 8 is inclined toward the outer end of the sleeve 2, and the pipeline 9 passes through the second elastic clamp 5, the flexible thermal insulation component 3 and the first elastic clamp 4 in sequence, and opens a circle of elastic petals 8 of the second elastic clamp 5, the insertion hole 3-1 of the flexible thermal insulation component 3 and a circle of elastic petals 8 of the first elastic clamp 4 in sequence. Since the diameter of the insertion hole 3-1 of the flexible thermal insulation component 3 is smaller than the diameter of the pipeline 9 in the initial state, after the pipeline 9 passes through the insertion hole 3-1, the flexible thermal insulation component 3 tightly wraps the pipeline 9, and the inner wall of the insertion hole 3-1 is in close contact with the surface of the pipeline 9 to form a sealing surface. At the same time, at the first elastic clamp 4, the elastic petal body 8 of the first elastic clamp 4 is pressed on the conical surface of the end of the flexible thermal insulation component 3, and the outer end of the flexible thermal insulation component 3 is in close contact with the surface of the pipeline 9 through the pressure of the elastic petal body 8; at the second elastic clamp 5, the elastic petal body 8 of the second elastic clamp 5 is pressed on the trumpet-shaped surface of the end of the flexible thermal insulation component 3, and the inner end of the flexible thermal insulation component 3 is in close contact with the inner wall of the sleeve 2 through the pressure of the elastic petal body 8.
[0033] When the end of the pipeline 9 is inserted into the sleeve 2 , the elastic petal 8 of the second elastic clamp 5 serves as a guide to accurately guide it into the insertion hole 3 - 1 of the flexible thermal insulation component 3 .
[0034] When the pipeline 9 needs to be connected from the outside of the wall 1 to the inside, the elastic petals 8 of the first elastic clip 4 and the elastic petals 8 of the second elastic clip 5 are both inclined toward the inside of the wall 1, the tapered end of the flexible thermal insulation component 3 is the inner end, and the bell-mouth end is the outer end, and the pipeline 9 passes through the first elastic clip 4, the flexible thermal insulation component 3 and the second elastic clip 5 in sequence.
[0035] A limiting boss 2-1 is provided at one end of the inner wall of the sleeve 2, and an internal thread 2-3 is provided at the other end. One of the first elastic clamp 4 and the second elastic clamp 5 contacts the limiting boss 2-1, and the other is connected to the internal thread 2-3 via an external thread.
[0036] For Figure 1 , Figure 2 In the structure, the first elastic clamp 4 is placed into the sleeve 2 from the end with the internal thread 2-3, and the first elastic clamp 4 moves to the other end until it contacts the limiting boss 2-1, and its position is limited by the limiting boss 2-1, and then the flexible thermal insulation component 3 is inserted into the sleeve 2 from the end with the internal thread 2-3 until the end of the flexible thermal insulation component 3 contacts the first elastic clamp 4, and finally the second elastic clamp 5 is screwed onto the internal thread 2-3 through threads. When the second elastic clamp 5 is completely entered into the sleeve 2, the end of the second elastic clamp 5 presses against the end of the flexible thermal insulation component 3.
[0037] The first elastic clamp 4 and the second elastic clamp 5 include a main body ring 7, and the elastic petal body 8 is located on the inner side of one end of the main body ring 7, wherein the front view of the first elastic clamp 4 is as shown in FIG. Figure 3 The main body ring 7 has a certain length, and the outer side of the main body ring 7 contacts the inner wall of the sleeve 2.
[0038] The present invention also includes a block 6 disposed in the sleeve 2. When the sleeve 2 is not temporarily needed for threading during use in the building, the block 6 is needed to temporarily block the sleeve 2. The block 6 is made of a heat-insulating material. When the block 6 is located at the end of the sleeve 2, the end face of the block 6 is flush with the surface of the wall 1. In order to ensure air tightness and heat preservation, a cylindrical heat-insulating material can be placed in the insertion hole 3-1 of the flexible heat-insulating member 3 to fill the insertion hole 3-1.
[0039] An end ring rib 2-2 is provided on the outer wall of the end of the sleeve 2, and the side surface of the end ring rib 2-2 is flush with the surface of the wall 1. The end ring rib 2-2 is used to ensure the airtightness between the sleeve 2 and the wall 1 on the one hand, and to make the joint position between the end of the sleeve 2 and the wall 1 neat and beautiful on the other hand.
[0040] For the case where the contour of the pipeline 9 is not an ideal circle, such as the pipeline 9 (including copper tubes, condensers and wires) connecting the indoor and outdoor units of the air conditioner, a winding tape is used to wrap the copper tubes, condensers and wires together, and the contour of its cross section is an irregular shape. After being inserted into the insertion hole 3-1, the surface of the air-conditioning pipeline 9 may not be in close contact with the flexible thermal insulation component 3. However, due to the presence of the first elastic clip 4 and the second elastic clip 5, the elastic petal body 8 presses the tapered end portion of the flexible thermal insulation component 3 tightly against the surface of the pipeline 9, thereby forming a sealing fit at this position, ensuring the overall airtightness.
[0041] The invention also discloses a method for using the above-mentioned assembled steel structure ultra-low energy consumption building wall sleeve, which comprises the following steps.
[0042] a. During the construction of the wall 1, a sleeve 2 is arranged inside the wall 1, and the sleeve 2 penetrates the wall 1.
[0043] b. Place the first elastic clamp 4 and the flexible heat-insulating member 3 in sequence inside the sleeve 2 from the end with the internal thread.
[0044] c. Screw the external thread of the second elastic member 5 onto the internal thread 2 - 3 at the end of the sleeve 2 , so that the elastic petal 8 of the second elastic member 5 is located in the sleeve 2 and in contact with the flexible insulation member 3 .
[0045] d. A blocking block 6 is arranged in the second elastic member 5 to seal the end of the sleeve 2 .
[0046] e. When it is necessary to pass the pipeline, remove the block 6 and pass the sleeve 2 from one end of the second elastic member 5 to the other end.
[0047] Furthermore, in step a, the sleeve 2 is arranged according to the pipeline connection direction, so that one end of the internal thread 2-3 of the sleeve 2 is located at the entry end of the pipeline. Generally, air conditioning pipelines pass through the sleeve from the inside of the wall, so the internal thread end of the sleeve is generally located on the inside of the wall.
[0048] When the pipeline 9 needs to be replaced or repaired, the second elastic member is first unscrewed from the internal thread 2-3, and then the pipeline 9 is pulled out from the sleeve 2, without causing damage to the components. After the pipeline 9 is replaced or repaired, the present invention can continue to be used.
[0049] The present invention is easy to use, can effectively ensure the air tightness in the wall bushing 2, is convenient for replacing or repairing the pipeline 9, and can be reused.
