Description

Technical Field

[0001] The present invention relates to an exterior wall pipe penetration construction technology, in particular to an exterior wall pipe penetration structure and a construction method for a passive ultra-low energy consumption green building. Background Art

[0002] Passive houses, also known as passive ultra-low energy green buildings, integrate various technologies and products. By fully utilizing renewable energy, they ensure that the total primary energy consumption does not exceed 120 kilowatt-hours per square meter per year. This low energy standard is achieved through high thermal and acoustic insulation, tightly sealed exterior walls, and renewable energy. Therefore, passive houses require excellent thermal insulation and airtightness.

[0003] For the external wall pipe penetration of passive houses, the sleeve is generally pre-installed and cast together with the external wall. Existing wall penetration pipes are installed using single-layer and double-layer pipe penetration structures. For example, the wall penetration waterproof structure disclosed in CN105909879A uses sealing paste and filling materials to waterproof the water-facing surface, and pre-buried screws, inner flanges, and inner baffles to seal the sealing ring from the inside. Another example is the wall penetration waterproof structure disclosed in CN112610755A. The water-facing surface is sealed with grouting columns, and the inside uses screws and connecting columns to compress the rainwater expansion material, and leak detection is performed from the inside. The common point of both is that the pipe penetration is carried out after the wall structure is completed. This results in complicated operation and poor integrity between the two-layer structure, and relatively poor waterproofing effect. At the same time, the waterproof sealing construction of the wall penetration pipe after the wall is formed is cumbersome and the sealing effect is poor. Therefore, a wall penetration structure that can solve the above problems and a device for solving the above wall penetration structure problems are still needed. Summary of the Invention

[0004] The present invention is to solve the problem of poor quality of waterproof, thermal insulation and sealing in the existing post-penetration waterproof, thermal insulation and sealing construction and the problem that the existing equipment is unable to complete the waterproof, thermal insulation and sealing by filling glue between double-layer sleeves during wall construction. The specific scheme is as follows: A passive ultra-low energy consumption green building exterior wall pipe-penetrating structure, including a pre-buried sleeve, a template and a glue injection device, a water stop ring and a connecting structure are installed on the outer side of the pre-buried sleeve, a glue injection port is opened on the pre-buried sleeve, a wall-penetrating pipe is interspersed in the interior of the pre-buried sleeve, a filling cavity is arranged between the wall-penetrating pipe and the pre-buried sleeve, the filling cavity and the glue injection port are interconnected, the template is fixed and installed by a connecting plate, screws and the pre-buried sleeve, the glue injection device includes a glue injection barrel, a glue injection head is installed at the bottom of the glue injection barrel, and a hook is installed on the glue injection barrel.

[0005] The above-mentioned double-layer structure of the wall-penetrating pipe can eliminate the requirements for the operation ability and position control ability of the construction personnel in the previous welding method of fixing the wall-penetrating structure. The use of the glue injection device can effectively solve the problem that the existing means do not have a device for effectively injecting glue into the double-layer pipe structure inside the steel structure.

[0006] The connection structure includes a plurality of groups of connection claws arranged circumferentially and along the length of the embedded sleeve.

[0007] The glue injection barrel and the glue injection port are both provided with two, and the hooking part includes a screw sleeve 1, two screw sleeves 2, two screw rods 1, and two screw rods 2. Both ends of the screw sleeve 1 are threadedly connected to the screw rod 1, the free end of the screw rod 1 is fixed to the glue injection barrel, the screw sleeve 2 is rotatably arranged on the screw rod 1, the screw rod 2 is threadedly installed on the free end of the screw sleeve 2, and a hooking structure is provided on the screw rod 2.

[0008] The connecting disk is provided with a cam-shaped groove and an air inlet, and an air bag is installed in the cam-shaped groove.

[0009] When the glue injection ports are located at both ends, the embedded sleeve can be a waist-shaped structure with a thin middle portion and thick ends.

[0010] When one of the glue injection ports is located at the end and the other glue injection port is located in the middle, the embedded sleeve can be a waist-shaped structure, which is thick in the middle and thin at both ends.

[0011] The two glue injection ports can both be used for glue injection, or one can be used for glue injection and the other for glue discharge.

[0012] A glue discharge port is provided in the middle of the embedded sleeve, and a one-way dredging structure is installed at the glue discharge port.

[0013] A construction method for a passive ultra-low energy consumption green building exterior wall pipe-through structure, wherein the wall-through structure is as described above, and the construction steps are as follows:

[0014] Pre-installation of embedded sleeves: After tying the exterior wall reinforcement, reserve space for the embedded sleeves. Rotate the embedded sleeves into the reserved space, and hook the connecting claws onto the reinforcement. Limit the vertical and horizontal movement of the embedded sleeves, or require at least three connections. The front-to-back position is fixed, and the connecting claws are tied / welded to the nearest reinforcement.

[0015] Glue injection: Adjust the distance between the two glue injection barrels’ glue injection heads through screw rod 1 and screw sleeve 1, insert the glue injection heads into the glue injection port, rotate screw sleeve 2 and / or adjust the extension length of screw rod 2 to hang the hook structure on the nearest steel bar;

[0016] Pipe penetration: insert the wall pipe inside the embedded casing, adjust the distance between the exposed steel bars at both ends of the wall pipe, connect the glue injection barrel to the external glue injection pipe to inject sealant into the filling cavity;

[0017] Template installation: Install the two sets of templates at both ends of the embedded casing respectively, and install a connecting plate on the outside of each set of templates. The connecting plate is fixed with the embedded casing by screws;

[0018] Pouring: Remove the glue injection device, install other components, and proceed with pouring. If leakage is found at the connecting plate during pouring, blow the airbag through the air inlet to fill the cam-shaped groove and seal the leakage point.

[0019] Compared with the existing technology, the present invention has the following advantages: first, it provides a new solution for the simultaneous construction of glue filling between the wall and the double-layer casing. The use of this construction solution can effectively ensure that the wall is formed first and then the pipe is constructed, which causes complicated operations and poor waterproof and thermal insulation sealing. It is more practical. The glue injection device is used for on-site operation inside the steel structure. After the embedded casing and the wall pipe are installed, the sealant filling construction of the filling cavity is carried out to ensure the overall waterproof and thermal insulation effect of the two. The strong adhesion of the sealant makes it impossible for the waterproof and thermal insulation mortar to achieve the effect. At the same time, the embedded sleeve can adopt a structure that is thin in the middle and thick at both ends or thick in the middle and thin at both ends, which is convenient for compaction after glue injection. A corresponding glue discharge port can also be set. The one-way dredging structure of the glue discharge port can be used to compact the injected glue. One end of the one-way dredging structure (PE film) adsorbs each other and is socketed in the embedded sleeve. When the dense sealant will push the one-way conductive structure, and glue leaks at the one-way dredging structure, it can be judged that the sealant fills the filling cavity. Subsequently, the glue inside the one-way conductive structure is drained out and then cone-backed into the filling cavity to form a sealing structure (the PE film will be adsorbed together to prevent leakage). In the subsequent water flow test, it can be directly judged according to the pressure gauge value during the water flow test, or without an external pressure gauge, it can be observed whether the one-way dredging structure has water accumulation and external top phenomenon. If the one-way conductive structure has external top phenomenon, it means that there is a gap inside the filling cavity. If not, it means that the seal is sufficient. The connection plate is used to prevent leakage that is easy to occur after direct installation using templates and embedded sleeves. When leakage occurs, the air bag can be blown through the air inlet to fill the cam-shaped groove and seal the leakage point. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Reference Figures 1 to 7 As shown, a passive, ultra-low-energy, green building exterior wall pipe-penetrating structure includes an embedded sleeve 1, a formwork 2, and a glue injection device. A waterstop ring 3 and a connecting structure 4 are installed on the outside of the embedded sleeve 1. The connecting structure 4 includes multiple connecting claws 11 arranged circumferentially and along the length of the embedded sleeve 1. The connecting claws 11 can be arranged in multiple rings or rotated along the axis to be installed by hooking and hooking with the nearest steel bar. During installation, the connecting claws 11 are connected to the corresponding steel bar by rotating the connecting structure 4. After the distance between the two ends of the embedded sleeve 1 and the corresponding formwork 2 is determined, the connected connecting claws 11 are welded or tied to the corresponding steel bar for fixed arrangement. The embedded sleeve 1 is provided with a glue injection port 6, which is used to fill the filling cavity between the embedded sleeve 1 and the wall-penetrating pipe 5 with sealant. The embedded sleeve 1 is interspersed with a wall-penetrating pipe 5, and a filling cavity is provided between the wall-penetrating pipe 5 and the embedded sleeve 1. The filling cavity and the glue injection port 6 are interconnected. The template 2 is fixedly installed by a connecting plate 7, a screw 8 and the end structure of the embedded sleeve 1. The glue injection device includes a glue injection barrel 9, a glue injection head 12 is installed at the bottom of the glue injection barrel 9, and a hook 10 is installed on the glue injection barrel 9. When injecting glue, the glue injection head 12 and the glue injection port 6 are docked, and the glue injection port 6 can adopt a stepped structure, which is conducive to filling into the interior. The hook 10 is conducive to hanging the glue injection barrel 9 on the steel bar, which is conducive to stable glue injection during glue injection. The glue injection barrel 9 is used to connect external glue injection equipment.

[0028] The glue injection barrel 9 and the glue injection port 6 are each provided with two hook members 10, each comprising a first screw sleeve 13, two second screw sleeves 14, two first screw rods 15, and two second screw rods 16. Both ends of the first screw sleeve 13 are threadedly connected to the first screw rod 15, and the free ends of the first screw rods 15 are fixed to the glue injection barrel 9. One second screw rod 16 is rotatably arranged on the first screw rod 15, and the two second screw rods 16 are threadedly mounted on the free ends of the second screw sleeve 14. The other second screw rod 16 is provided with a hook structure 17. The hook structure 17, the first screw rod 15, the second screw rod 16, the first screw sleeve 13, and the second screw sleeve 14 allow for adjustment of the spacing, while also consolidating the glue injection barrel 9 to the nearest steel bar, thereby ensuring stable docking between the glue injection barrel 9 and the glue injection port 6 and structural stability during glue injection.

[0029] like Figure 7 As shown, a cam-shaped groove 18 and an air inlet 19 are provided on the connecting plate 7, both of which are arranged on the side opposite to the template 2. An air bag 20 is installed in the cam-shaped groove 18. If the concrete mortar leaks at this location, air can be supplied to the inside of the air bag 20 through the air inlet 19, thereby eliminating the hidden danger of leakage. At the same time, a one-way valve is installed at the air inlet 19 to prevent air leakage.

[0030] In one embodiment, when the glue injection ports 6 are located at both ends, the embedded sleeve 1 can be a waist-shaped structure with a narrow middle portion and wide ends. The thin middle portion and wide ends ensure that the filling cavity between the embedded sleeve 1 and the wall-penetrating pipe 5 is tightly sealed with sealant.

[0031] One of the implementation methods: when one of the injection ports 6 is located at the end and the other injection port 6 is located in the middle, the embedded sleeve 1 can be a waist-shaped structure, which is thick in the middle and thin at both ends. The injection port 6 in the middle can discharge the internal air from there, which is also conducive to the enrichment of the sealant.

[0032] In one embodiment, both of the two glue injection ports 6 are used for glue injection, or one is used for glue injection and the other is used for glue discharge. The glue injection / drainage function can be selected according to actual needs.

[0033] One implementation method: Figure 5 、 Figure 7 As shown, a glue discharge port is provided in the middle of the embedded sleeve 1, and a one-way dredging structure 21 is installed at the glue discharge port. The one-way dredging structure 21 is composed of two pieces of PE films that are attracted to each other (statically). The one-way dredging structure 21 of the glue discharge port can be used to easily distinguish the degree of internal glue injection. At the same time, after the one-way dredging structure 21 is found to have glue discharged, the sealant inside the one-way dredging structure is drained out and then injected back into the filling cavity to form a sealing structure. In the subsequent water flow test, it can be directly judged based on the pressure gauge value during the water flow test, or without an external pressure gauge, it can be observed whether the one-way dredging structure has water accumulation and external push-up phenomenon. If there is external push-up phenomenon, it means leakage, and if not, it means that the seal is sufficient.

[0034] A construction method for a passive ultra-low energy consumption green building exterior wall pipe structure, the construction steps are as follows:

[0035] Pre-installation of embedded sleeve 1: After tying the exterior wall reinforcement, reserve space for installing embedded sleeve 1. Rotate embedded sleeve 1 into the reserved space. Hook connecting claw 11 on the reinforcement. It is required to limit the movement of embedded sleeve 1 in the up, down, left, and right directions or require at least three groups of connections. The position in the front and back directions is fixed. Tie / weld connecting claw 11 to the nearest reinforcement.

[0036] Glue injection: Adjust the distance between the glue injection heads 12 of the two glue injection barrels 9 through the screw 15 and the screw sleeve 13, insert the glue injection head 12 into the glue injection port 6, rotate the screw sleeve 2 14 and / or adjust the extension length of the screw 2 16 to hang the hook structure 17 on the nearest steel bar;

[0037] Pipe insertion: insert the wall-penetrating pipe 5 inside the embedded casing 1, adjust the distance between the exposed steel bars at both ends of the wall-penetrating pipe 5, and connect the glue injection barrel 9 to the external glue injection pipe to inject sealant into the filling cavity;

[0038] Installation of template 2: Install two sets of templates 2 at both ends of the embedded sleeve 1 respectively. Install a connecting plate 7 on the outside of each set of templates 2. Connect the connecting plate 7 to the embedded sleeve 1 with screws 8;

[0039] Casting: Install other components and cast. When leakage is found at the connection plate 7 during casting, blow the air bag 20 through the air inlet 19 to fill the cam groove 18 to seal the leakage point.
