Description

Technical Field

[0001] This utility model relates to the field of bridge wet joint template technology, specifically to a connecting device and a support system. Background Art

[0002] A wet joint in a bridge refers to a joint where prestressed concrete beams are prefabricated in sections and then connected into a whole by cast-in-place concrete.

[0003] The prior art discloses a quick-installation and dismantling suspended formwork for wet joints of bridge decks, such as... Figure 1 As shown, the suspended formwork includes a bottom formwork 01, lifting rings 02, lifting rods 03, and support rods 04. The upper surface of the bottom formwork 01 abuts against the lower surface of two precast beams 05. Lifting rings 02 are fixedly connected to the bottom formwork 01, and multiple lifting rods 03 are symmetrically arranged on both sides of the bottom formwork 01. The bottom end of the lifting rod 03 is fixedly connected to the bottom formwork 01, and the top end is fixedly connected to the support rod 04. The support rod 04 supports the space between the upper surfaces of the two precast beams 05. The lifting rings 02 are used to lift the suspended formwork between the two precast beams 05. Concrete is poured into the space enclosed by the bottom formwork 01 and the two precast beams 05. The suspended formwork between the two precast beams 05 allows for the pouring of concrete to seal the wet joint. However, after the concrete is poured, the bottom formwork 01 needs to be removed from one side of the lower surface of the precast beams 05. The bottom formwork 01 is prone to falling and causing danger. If more support measures are used for protection, the demolding efficiency will be reduced. Utility Model Content

[0004] In view of this, the present invention provides a connecting device and a support system to solve the problem that when the bottom formwork is removed from one side of the lower surface of the precast beam after the concrete is poured, the bottom formwork is prone to fall and cause danger, and if more support measures are used for protection, the formwork removal efficiency will be reduced.

[0005] In a first aspect, this utility model provides a connecting device for fixedly connecting two spaced-apart components to be connected, comprising:

[0006] A first support component is disposed between the two components to be connected, and the lower surface of the first support component closes the gap between the lower surfaces of the two components to be connected.

[0010] Beneficial effects: By connecting the two components to be connected as a whole, the concrete, the first support component, and the connectors are integrated. It is not necessary to remove the first support component after the concrete is poured, and thus no support measures are required. This simplifies the construction process, improves construction efficiency, shortens the construction cycle, and avoids the danger to operators caused by falling objects from heights.

[0011] In one alternative embodiment, the dimension of the lower surface of the first support component perpendicular to its extension length direction is not less than the distance between the two components to be connected.

[0012] In one alternative implementation, the dimension of the lower surface of the first support component perpendicular to its extension length direction is greater than the distance between the two components to be connected.

[0013] Beneficial effects: By setting the size of the lower surface of the first support component to be greater than the distance between the two parts to be connected, it is easier to fix the position of the first support component, so that the first support component and the parts to be connected are closely attached and are not prone to relative movement.

[0014] In one alternative embodiment, a sealing element is provided at the connection between the first support component and the component to be connected.

[0015] Beneficial effect: By setting up sealing components, leakage of grout during concrete pouring can be prevented, thus affecting the construction quality.

[0016] In one optional implementation, the first support component includes:

[0017] A first support member is disposed between the two components to be connected, for sealing the gap between the lower surfaces of the two components to be connected.

[0019] In one optional implementation, the first support component includes:

[0020] A reinforcing member is fixedly connected to the first support member and is disposed on the side close to the member to be connected. The reinforcing member is disposed at an angle to the plane of the first support member.

[0021] And / or, the hoisting part is fixedly connected to the first support member for fixed connection with the connecting member.

[0022] Beneficial effects: By setting up reinforcing members, the structural strength of the first support component can be improved, and the integrity of the first support component and the concrete can be improved, preventing the first support component from falling and causing danger during use; by setting up a hoisting part, the connection between the connector and the first support component can be improved, preventing the first support component from falling and causing danger before the concrete is poured.

[0023] In one alternative implementation, the reinforcement is a truss structure.

[0024] Beneficial effects: By using a truss structure as a reinforcing member, the structure has high strength and can improve the connection strength between the concrete and the first supporting member.

[0025] In one optional embodiment, the second support component includes a plurality of second support members, which are spaced apart and are correspondingly arranged with the connector.

[0026] Beneficial effects: By setting multiple second support components, the connection strength between the second support component and the first support component can be improved, and the first support component is less likely to fall off and cause danger before concrete is poured.

[0027] In one alternative implementation, each of the second supports is fixedly connected to the first support assembly via a plurality of the connectors.

[0028] Beneficial effect: Each second support member is fixedly connected to the first support assembly through multiple connectors, which can improve the connection strength between the second support member and the first support assembly.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] The following is combined Figures 2 to 6 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, a connecting device is provided for fixedly connecting two spaced-apart components 1 to be connected, comprising: a first support component 2 disposed between the two components 1 to be connected, the lower surface of the first support component 2 sealing the gap between the lower surfaces of the two components 1 to be connected; a second support component 3 fixed between the upper surfaces of the two components 1 to be connected, the second support component 3 being angled to the components 1 to be connected; and a connecting component 4, one end of which is fixedly connected to the first support component 2, and the other end of which is fixedly connected to the second support component 3; the first support component 2, the second support component 3, and the two components 1 to be connected form a casting space, in which concrete is poured, and the concrete, the first support component 2, and the connecting component 4 together form a whole for connecting the two components 1 to be connected.

[0046] By connecting the two components 1 to be connected as a whole, the concrete, the first support component 2, and the connector 4 are used as a whole. It is not necessary to remove the first support component 2 after the concrete is poured, and thus no support measures are required. This simplifies the construction process, improves construction efficiency, shortens the construction cycle, and avoids the danger to operators caused by falling objects from heights.

[0047] In this embodiment, the up and down direction is... Figure 4 The vertical direction in the middle.

[0048] In this embodiment, the component to be connected, 1, is a precast box girder. As an alternative implementation, the component to be connected, 1, can also be a cast-in-place box girder, or other building components, or other structures; no further restrictions are imposed here.

[0049] In this embodiment, the first support component 2 is prefabricated in the factory. After the prefabricated box girders are hoisted, the first support component 2 is then hoisted between the prefabricated box girders. As an alternative implementation, the first support component 2 can also be tied to one end of one of the prefabricated box girders and hoisted simultaneously.

[0050] like Figures 5-6 As shown, the first support component 2 in this embodiment includes a first support member 21, disposed between two precast box girders, used to seal the gap between the lower surfaces of the two precast box girders. The first support member 21 is a precast galvanized template. By setting the first support member 21, the gap between the lower surfaces of the two precast box girders can be sealed, and a supporting surface can be provided for pouring concrete. Using a galvanized template prevents the surface of the template from rusting after prolonged use, thus affecting the aesthetics of the precast box girders. Alternatively, the first support member 21 can be a steel plate template, a stainless steel template, or a template made of other materials; no further restrictions are imposed here.

[0051] like Figures 5-6As shown, the first support component 2 in this embodiment includes a reinforcing member 22, which is fixedly connected to the first support component 21 and disposed near the side of the precast box girder. The reinforcing member 22 is disposed at an angle to the plane of the first support component 21. By providing the reinforcing member 22, the structural strength of the first support component 2 can be improved, and the integrity of the first support component 2 and the concrete can be improved, preventing the first support component 2 from falling off and causing danger during use. As an alternative implementation, the reinforcing member 22 may not be provided, and no further restrictions are imposed here.

[0052] like Figures 5-6 As shown, the reinforcing member 22 in this embodiment is a truss structure. Specifically, the truss structure includes: web members 221, multiple of which are spaced apart along the extension length direction of the first support member 21 and perpendicular to the extension length direction of the first support member 21, and every two web members 221 are symmetrically arranged and adjacent to each other along the extension length direction of the first support member 21, and the cross-section of the web members 221 is "∧" shaped; upper chord members 222, fixedly connected between the top ends of two adjacent web members 221, and arranged perpendicular to the extension length direction of the first support member 21; lower chord members 223, fixedly connected to the lower ends of multiple web members 221, and arranged perpendicular to the extension length direction of the first support member 21; edge sealing horizontal members 224, fixedly connected between multiple lower chord members 223, and arranged along the extension length direction of the first support member 21; and edge sealing vertical members 225, one end of which is fixedly connected to the first support member 21, and the other end of which is fixedly connected to the end of the upper chord member 222. Among them, the web member 221, the upper chord member 222, the lower chord member 223, the horizontal edge band 224, and the vertical edge band 225 are all reinforced steel members. By using a truss structure as the reinforcing member 22, the structure has high strength and can improve the connection strength between the concrete and the first supporting member 21.

[0053] like Figure 5 As shown, the first support component 2 in this embodiment includes a lifting part 23, which is fixedly connected to the first support member 21 and used for fixed connection with the connector 4. The lifting part 23 is a lifting point reinforcing bar with a "∧" shaped cross-section. By providing the lifting part 23, the connection tightness between the connector 4 and the first support member 21 can be improved, preventing the first support component 2 from falling and causing danger before concrete is poured. As an alternative implementation, the lifting part 23 can also be a sleeve structure, with the connector 4 passing through the cavity of the sleeve structure and extending out of the cavity at both ends. Alternatively, the lifting part 23 can be omitted, and one end of the connector 4 can be welded to the first support member 21.

[0054] like Figure 4As shown, in this embodiment, the dimension of the lower surface of the first support component 2 perpendicular to its extension length direction is greater than the distance between the two precast box girders. By setting the dimension of the lower surface of the first support component 2 to be greater than the distance between the two precast box girders, it is easier to fix the position of the first support component 2, so that the first support component 2 is tightly attached to the precast box girders and is not prone to relative movement. As an alternative implementation, the dimension of the lower surface of the first support component 2 perpendicular to its extension length direction may also be equal to the distance between the two precast box girders.

[0055] In this embodiment, a sealing component is provided at the connection between the first support component 2 and the precast box girder. The sealing component is made of foam adhesive. By providing the sealing component, leakage of grout during concrete pouring can be prevented, thus avoiding any impact on construction quality. As an alternative implementation, the connection between the first support component 2 and the precast box girder can also be sealed with edge-sealing tape or other flexible materials such as rubber.

[0056] like Figures 2-3 As shown, the second support component 3 in this embodiment includes multiple second support members 31, which are spaced apart and correspondingly arranged with the connecting member 4. The second support members 31 are suspended reinforcing bars that can be reused after removal. By providing multiple second support members 31, the connection strength between the second support component 3 and the first support component 2 can be improved, preventing the first support component 2 from falling off and causing danger before concrete is poured. As an alternative implementation, the second support member 31 can also be other building components such as steel pipes or steel columns; no further restrictions are imposed here.

[0057] like Figure 3 As shown, in this embodiment, each second support member 31 is fixedly connected to the first support assembly 2 via multiple connectors 4. The connectors 4 are fastening steel wires. The fixed connection of each second support member 31 to the first support assembly 2 via multiple connectors 4 improves the connection strength between the second support member 31 and the first support assembly 2. Alternatively, each second support member 31 may be fixedly connected to the first support assembly 2 via one or two connectors 4; no further limitations are imposed here. As an alternative implementation, the connectors 4 may also be other connecting structures such as connecting ropes or slings; no further limitations are imposed here.

[0058] According to an embodiment of the present invention, another aspect provides a support system, comprising: two precast box girders spaced apart; and the aforementioned connecting device fixedly connected between the two precast box girders.

[0059] The construction steps of the support system in this embodiment are as follows:

[0060] Step 1: Hoisting the precast box girders;

[0061] Step 2: Hoist the first support component 2 between the precast box girder and seal the connection with foam adhesive;

[0062] Step 3: Tie the steel wires securely and thread the suspended reinforcing bars through the opening formed by the steel wires.

[0063] Step 4: Pour concrete between the precast box girder and the precast galvanized formwork to complete the construction.

[0064] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
