Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to an inner plug-in assembled station connection device. Background Art

[0002] At present, the node processing methods of prefabricated stations mainly adopt cast-in-place nodes, mortise and tenon connections, plug-in connections, corbel anchor connections, bolt connections, etc. Among them, cast-in-place node connections use cast-in-place concrete at the nodes; mortise and tenon connections and plug-in connections are mainly connected by making concave and convex tenons at both ends of the connector; corbel anchor connections and bolt connections mainly rely on bolts and anchors to connect the nodes.

[0003] The node connection of the existing technology mainly relies on cast-in-place treatment at the node, such as cast-in-place node, tongue-and-groove connection, plug-in connection, etc. Although prefabricated components are used, they still need to be cast-in-place when connected. Since cast-in-place concrete takes a certain amount of time to produce high strength, it generally takes 28 days.

[0004] Among them, the corbel anchor connection and bolt connection mainly rely on the anchor and bolt connection. In the earthquake resistance of subway stations, the reliability of these nodes is very important and they are easily damaged in earthquakes.

[0005] The above connection methods, the connection of prefabricated assembled components, except for the cast-in-place nodes, have poor integrity and are prone to water seepage at the nodes, which cannot meet the underground waterproofing requirements of subway stations. Summary of the invention

[0006] The purpose of the present invention is to provide an inner-plug type assembled station connection device, which has a simple structure, is easy to construct and install, and has high strength and strong earthquake resistance.

[0008] Preferably, a protrusion is provided in the slide groove, and an elastic reset device is provided at the bottom of the protrusion.

[0009] Preferably, the connecting pipe body includes a first horizontal connecting pipe and a second horizontal connecting pipe arranged in parallel in the horizontal direction and a first vertical connecting pipe and a second vertical connecting pipe arranged in the vertical direction. The first horizontal connecting pipe, the second horizontal connecting pipe, the first vertical connecting pipe and the second vertical connecting pipe are interconnected to form a U-shape. The first connecting end and the second connecting end are respectively arranged on the first vertical connecting pipe and the second vertical connecting pipe. The infusion port and the exhaust port are arranged on the horizontal connecting pipe connecting the first vertical connecting pipe and the second vertical connecting pipe.

[0010] Preferably, a step surface is formed between the first connecting end and the first vertical connecting pipe.

[0011] Preferably, the protrusion is a steel bar.

[0012] Preferably, the filling port and the exhaust port are both provided with covers.

After the mortar pouring is completed, the inner plug type assembled station connection device is connected to the first component and the second component, and the component integrity is good. The nodes using this connection method have stronger seismic resistance than the nodes of the mortise and tenon connection and the plug-in connection. The use of high-strength mortar poured into the connecting pipe body can ensure that there is still a grip force on the outside of the plug-in part, thereby enhancing the force strength of the node; at the same time, due to the early strength effect of the mortar, compared with the cast-in-place node, the construction operation time of the node in this embodiment can be shortened to meet the requirements of rapid assembly of the assembled station.

DETAILED DESCRIPTION

[0022] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0023] It should be understood that the present invention uses the terms "first", "second", "third", "fourth", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figures 1 to 3As shown, an inner plug type assembled station connection device 3 of a preferred embodiment of the present invention, the assembled station includes a plurality of first components 1 and a second component 2, the inner plug type assembled station connection device 3 includes a connecting pipe body, the connecting pipe body includes a first connecting end and a second connecting end, the first connecting end is connected to the first component 1 by a thread, the second connecting end is provided with a connecting port (not shown in the drawings) adapted to the second component 2, a protrusion is provided on the second component 2, the protrusion is inserted in the connecting port, a cover plate 4 and a slide groove 5 for the cover plate 4 to slide are provided in the connecting port, a connecting hole (not shown in the drawings) matching the protrusion is provided on the cover plate, the protrusion passes through the connecting hole through the cover plate 4 and is inserted into the connecting port, a limiting mechanism for limiting the position of the cover plate 4 is provided at the end of the connecting port, thereby limiting the position of the cover plate 4 by the limiting mechanism to prevent the cover plate 4 from falling from the connecting port, the cover plate 4 is slidably installed in the slide groove 5, and the cover plate 4 plays a role in blocking the connecting port, and a pouring port 35 and an exhaust port 36 are provided in sequence on the connecting pipe body, thereby facilitating the pouring of high-strength mortar, exhausting and observing the pouring condition.

[0026] Based on the above technical scheme, the first component 1 and the second component 2 are connected through the inner plug type assembled station connection device 3. The inner plug type assembled station connection device 3 connects the first component 1 and the second component 2 on both sides of the prefabricated assembly. High-strength mortar can be poured into the connecting pipe body through the pouring port 35. When the high-strength mortar fills the connecting pipe body, mortar will flow out of the exhaust port 36, which makes it easy to determine that the pouring is completed. When the mortar pouring is completed, the inner plug type assembled station connection device 3 is connected to the first component 1 and the second component 2, and the integrity of the components is good. The nodes using this connection method have stronger seismic resistance than the nodes of the mortar-groove connection and the plug-in connection. The use of high-strength mortar poured into the connecting pipe body can ensure that there is still a grip force on the outside of the plug-in part, thereby enhancing the force strength of the node; at the same time, due to the early strength effect of the mortar, compared with the cast-in-place node, the construction operation time of the node in this embodiment can be shortened to meet the requirements of rapid assembly of the assembled station.

[0027] Furthermore, a protrusion 7 is provided in the slide groove 5, and an elastic reset device is provided at the bottom of the protrusion 7, so that when the cover plate 4 is poured with high-strength mortar, the cover plate 4 slides toward the limiting mechanism in the slide groove 5, and the force of pouring the high-strength mortar pushes the cover plate 4, and the cover plate 4 pushes and squeezes the protrusion 7 so that the elastic reset device is forced to retract into the slide groove 5, and the cover plate 4 continues to slide toward the limiting mechanism. When the cover plate 4 passes the limiting structure, the elastic reset device lifts the protrusion 7, so that the cover plate 4 cannot move in the opposite direction, ensuring that the strength of the connection is sufficient. Specifically, a slope is provided on the top of the protrusion 7, and the slope gradually rises from the first component 1 to the second component 2, thereby facilitating the movement of the cover plate 4 when pouring high-strength mortar. At the same time, it can also play a guiding role when the cover plate 4 slides toward the second component 2 in the slide groove 5. When the cover plate 4 slides over the protrusion 7 along the slope, the elastic reset device under the protrusion 7 will be compressed. After the cover plate 4 slides over the protrusion 7, the elastic reset device is reset and the protrusion 7 is lifted up. Therefore, the cover plate 4 is limited by the protrusion 7 and the limiting device at this time, and the cover plate 4 can no longer move in the opposite direction.

[0028] Specifically, the connecting pipe body includes a first horizontal connecting pipe 31 and a second horizontal connecting pipe 32 arranged in parallel in the horizontal direction, and a first vertical connecting pipe 33 and a second vertical connecting pipe 34 arranged in the vertical direction. The first horizontal connecting pipe 31, the second horizontal connecting pipe 32, the first vertical connecting pipe 33 and the second vertical connecting pipe 34 are interconnected to form a square shape. The first horizontal connecting pipe 31, the second horizontal connecting pipe 32, the first vertical connecting pipe 33 and the second vertical connecting pipe 34 are interconnected to form a quadrilateral, thereby ensuring that the strength of the inner plug-type assembled station connection device 3 is high after the mortar is poured to avoid damage. The first connecting end and the second connecting end are respectively arranged on the first vertical connecting pipe 33 and the second vertical connecting pipe 34. In the present embodiment, the first connecting end and the second connecting end are respectively arranged opposite to the first horizontal connecting pipe 31 and the second horizontal connecting pipe 32, thereby facilitating the flow of mortar and ensuring the reliability of the connection of each component after grouting. The pouring port 35 and the exhaust port 36 are arranged on the horizontal connecting pipe connecting the first vertical connecting pipe 33 and the second vertical connecting pipe 34, thereby facilitating checking whether the pouring is completed during pouring, and facilitating the assembly and fixed connection of the first component 1 and the second component 2 with the inner plug-type assembled station connection device 3.

[0029] In this embodiment, a step surface is formed between the first connecting end and the first vertical connecting pipe 33, thereby facilitating rapid installation and positioning between the inner plug-in assembled station connection device 3 and the first component 1 during installation.

[0030] In this embodiment, the protrusion is a steel bar. This facilitates the connection between the inner plug type assembled station connection device 3 and the first component 1 and the second component 2. The cover plate 4 is provided with a mounting hole adapted to the steel bar, and the diameter of the connection hole is equal to the nominal diameter of the steel bar. The length of the steel bar is greater than 1 / 2 of the length of the horizontal connecting pipe, thereby ensuring that the inner plug type assembled station connection device 3 and the second component 2 can be connected reliably and with high strength after pouring mortar.

[0031] Preferably, a cover 37 is provided on the filling port 35 and the exhaust port 36, thereby ensuring that after the mortar is poured, the inner plug-type assembled station connection device 3 can be sealed and not affected by the outside world, and the mortar will not leak, further ensuring a reliable connection.

[0032] Furthermore, a waterproof layer is provided between the inner plug type assembled station connection device 3 and the first component 1 and the second component 2. Thus, the waterproof requirement is met. In this embodiment, the waterproof layer is EPDM rubber. The EPDM rubber is compacted by the deadweight of the side wall above the inner plug type assembled station connection device 3 later, so as to meet the waterproof requirement of the underground station.

[0033] Preferably, the limiting mechanism is a retaining ring 6, which is welded to the connection port, thereby limiting the cover plate 4 and ensuring that the cover plate 4 does not slip out of the groove when pouring mortar.

[0034] Furthermore, the inner wall of the retaining ring 6 is trumpet-shaped, and the inner diameter of the retaining ring 6 gradually increases from the connecting opening to the outside, thereby facilitating the insertion of the protruding portion of the second component 2 into the connecting opening.

[0035] In this embodiment, the first component 1 is provided with a first component connecting end 11, which is provided with threads, and the second component 2 is provided with a second component connecting end 21, thereby facilitating the connection between the first component 1 and the second component 2 and the connecting device.

[0036] The working process of the present invention is: tighten the first component connection end 11 and the inner plug type assembled station connection device 3 through threads. During the tightening process, the pouring port 35 and the exhaust port 36 should be set on the outside of the inner plug type assembled station connection device 3 to facilitate grouting. During the assembly process of the first component 1 and the second component 2, first accurately position the first component 1 and the second component 2, then insert the steel bars reserved in the second component 2 into the connection hole, align the second component connection end 21 with the connection port and insert it, and then pour high-strength mortar into the pouring port 35 until slurry emerges from the exhaust port 36, and then stop grouting, wherein the pouring port 35 is set for grouting, and the exhaust port 36 is for detecting whether the inside is full of slurry. Due to the pressure of grouting, the cover plate 4 slides in the cover plate 4 slide groove 5 toward the second component 2 until the cover plate 4 slides to the retaining ring 6. At this time, since the chute 5 has been preset with a protrusion 7 with an elastic reset device at the bottom, when the cover plate 4 is poured with high-strength mortar, it slides toward the limit mechanism in the chute 5, and the force of pouring high-strength mortar pushes the cover plate 4, and the cover plate 4 pushes and squeezes the protrusion 7 so that the elastic reset device is forced to retract into the chute 5, and the cover plate 4 continues to slide toward the limit mechanism. When the cover plate 4 passes the limit structure, the elastic reset device lifts the protrusion 7, so that the cover plate 4 cannot move in the opposite direction. At this time, the cover 37 can be covered, and after the high-strength mortar exerts its strength, the first component 1 and the second component 2 have been connected to form a whole. For the side wall of the underground station, since waterproofing needs to be considered, EPDM rubber can be used at the interface, and the EPDM rubber is compacted by the self-weight pressure of the upper side wall of the plug-in assembled station connection device 3 to meet the waterproofing requirements of the underground station. In addition, it is necessary to accurately align the steel bars of the first component 1 and the second component 2 during production, so that the steel bars of the two components can be inserted into the grouting sleeve after leaving the factory.

[0037] In summary, the embodiment of the present invention provides an inner plug type assembled station connection device 3, wherein the inner plug type assembled station connection device 3, the first component 1 and the second component 2 are connected through the inner plug type assembled station connection device 3, the inner plug type assembled station connection device 3 connects the first component 1 and the second component 2 on both sides of the prefabricated assembly, and high-strength mortar can be poured into the connecting pipe body through the pouring port 35. When the high-strength mortar fills the connecting pipe body, mortar will flow out of the exhaust port 36, which is convenient for determining that the pouring is completed. When the mortar pouring is completed, the inner plug type assembled station connection device 3 is connected to the first component 1 and the second component 2, and the integrity of the components is good. The nodes using this connection method have stronger seismic resistance than the nodes of the mortar-groove connection and the plug-in connection. The use of high-strength mortar poured into the connecting pipe body can ensure that there is still a gripping force on the outside of the plug-in part, thereby enhancing the force strength of the node; at the same time, due to the early strength effect of the mortar, compared with the cast-in-place node, the construction operation time of the node in this embodiment can be shortened to meet the requirements of rapid assembly of the assembled station.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
