Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to an assembled connecting component for connecting steel pipe columns and plate beams. Background Technology

[0002] The cut-and-cover construction method has been widely used as an economical and effective method for foundation pit construction. The construction of precast steel pipe columns and slab beam support structures is a key part of the cut-and-cover construction method, and the rationality of its design and the state of construction directly affect the safety of the foundation pit project.

[0003] Currently, the connection between steel pipe columns and slab beams during construction is achieved by welding steel brackets to the outside of the steel-concrete composite column. Firstly, this connection requires high precision in machining and installation methods. The steel pipe column is complex to manufacture, and internal plug welding is difficult. On-site welding involves a large amount of work, and weld quality cannot be guaranteed. Secondly, space constraints when lowering the steel pipe column into the foundation pit prevent the placement of welded brackets. The bracket dimensions must be modified before welding to the slab beam reinforcement. Due to space limitations, weld quality often fails to meet requirements, resulting in poor load-bearing capacity, high construction difficulty, numerous safety hazards, and a relatively long construction period, increasing the cost of steel pipe pile installation. Therefore, this utility model provides a prefabricated connection component for connecting steel pipe columns and slab beams to solve the above problems. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0030] Example 1

[0031] This utility model embodiment provides an assembled connecting component for connecting steel pipe columns and slab beams, including a steel pipe column 1, a slab beam connector, and two reinforcing ring plates 2. The steel pipe column 1 is prefabricated and inserted into the foundation pit pile point. The assembled slab beam connector is used to connect the steel pipe column 1 to the slab beam structure.

[0032] like Figures 1-5 As shown, two reinforcing ring plates 2 are distributed vertically and are respectively fitted onto the outside of the steel pipe column 1, and are fixedly connected to the steel pipe column 1. Horizontal ring plates 3 are fixedly installed on the two reinforcing ring plates 2, which can enhance the connection strength between the horizontal ring plates 3 and the steel pipe column 1.

[0033] Two sets of plate beam connectors are provided, symmetrically arranged on both sides of the steel pipe column 1, and the plate beam connectors are distributed between the two reinforcing ring plates 2. The two reinforcing ring plates 2 are concave at the plate beam connector locations to avoid affecting the connection between the plate beam connectors and the steel pipe column 1.

[0034] The two sets of plate beam connectors each include two through brackets 4 and two external brackets 5. The through brackets 4 are fixedly connected to the steel pipe column 1, and the external brackets 5 are detachably fixedly connected to the through brackets 4. The extended part of the external brackets 5 is used to support the plate beam structure. The plate beam structure is fixedly connected to the steel pipe column 1 through the external brackets 5 and the through brackets 4.

[0035] Example 2

[0036] The main structure of this embodiment is the same as that of embodiment 1. The difference is that this embodiment limits the structure and installation method of the through-hole bracket 4 and the external bracket 5.

[0037] Specifically, such as Figures 1-2 As shown, both the through-bracket 4 and the outer bracket 5 are U-shaped structures, and are horizontally distributed. The outer bracket 5 is fitted inside the through-bracket 4, and the web and two wing plates of the through-bracket 4 are respectively attached to the web and two wing plates of the outer bracket 5. The web of the through-bracket 4 is vertically distributed, and the two wing plates are horizontally distributed.

[0038] like Figure 2As shown, two U-shaped grooves 11 adapted to the through-hole bracket 4 are respectively opened on both sides of the steel pipe column 1. The two U-shaped grooves 11 are mirror symmetrical, with their openings facing outwards, and the U-shaped grooves 11 are located between the two reinforcing ring plates 2. The through-hole bracket 4 extends through the U-shaped grooves 11 into the interior of the steel pipe column 1 and is welded and fixed to the steel pipe column 1.

[0039] In addition, the web of the through-bracket 4 is provided with 8 first through holes, and the two wing plates of the through-bracket 4 are each provided with 2 first through holes. Correspondingly, the web of the outer bracket 5 is provided with 8 second through holes, and the two wing plates of the outer bracket 5 are each provided with 2 second through holes. The through-bracket 4 and the outer bracket 5 are fixedly connected by inserting bolts 9 into the corresponding first and second through holes and screwing them in. The nuts of the bolts 9 are all facing outwards. Each through-bracket 4 and the outer bracket 5 are connected and fixed with 12 high-strength bolts 9.

[0040] The external corbel 5 is pre-installed between the slab beams. Once the steel pipe column 1 is inserted into the designated position of the foundation pit pile point, the external corbel 5 is then connected to the through corbel 4, so that the stress of the slab beam is fully transferred to the steel pipe column 1 through the corbel.

[0041] In this embodiment, the through-hole bracket and the external bracket are designed to be bolted together, which can reasonably solve the problem of inconvenient welding on the construction site, solve the problem of difficult control of on-site welding quality, greatly improve the convenience of construction, and ensure the strength and quality of the structure.

[0042] Example 3

[0043] The main structure of this embodiment is the same as that of embodiment 2, except that the setting method of the horizontal ring plate 3 is limited in this embodiment.

[0044] Specifically, such as Figures 1-3 As shown, in the two reinforcing ring plates 2, the upper reinforcing ring plate 2 is fixed with four horizontal ring plates 3. The four horizontal ring plates 3 are divided into upper and lower layers, with two horizontal ring plates 3 in each layer being mirror-symmetrical and distributed on the same horizontal plane. The lower reinforcing ring plate 2 is fixed with two horizontal ring plates 3, which are also mirror-symmetrical and distributed on the same horizontal plane. Space is left above and below each layer of horizontal ring plates 3 to support the reinforcing steel bars and other force-transmitting structures of the slab beam.

[0045] The horizontal ring plate 3 is welded and fixed to the reinforcing ring plate 2. In other embodiments of this utility model, the horizontal ring plate 3 can also be welded and fixed to both the reinforcing ring plate 2 and the steel pipe column 1. The surface of the horizontal ring plate 3 is provided with several ventilation holes to maintain stable air pressure during concrete pouring.

[0046] In addition, three transverse stiffening steel ring plates 12 are provided to enhance the steel pipe column 1's ability to resist transverse forces, such as... Figure 2As shown, the transverse stiffening steel ring plate 12 is welded and fixed inside the steel pipe column 1. The three transverse stiffening steel ring plates 12 are distributed on the same horizontal plane as the three layers of horizontal ring plates 3. The center of the transverse stiffening steel ring plate 12 is provided with a through hole for concrete to pass through, and the surface of the transverse stiffening steel ring plate 12 is provided with several vent holes for subsequent concrete pouring to release air and balance air pressure.

[0047] Example 4

[0048] The main structure of this embodiment is the same as that of embodiment 3, except that this embodiment also has a reinforcing mechanism.

[0049] Specifically, such as Figures 1-4 As shown, the reinforcing mechanism includes an upper reinforcing plate 6, a lower reinforcing plate 7, and 10 reinforcing ribs 8. The upper reinforcing plate 6 and the lower reinforcing plate 7 are distributed vertically and have the same shape. The size of the upper reinforcing plate 6 is larger than that of the lower reinforcing plate 7. The surfaces of the upper reinforcing plate 6 and the lower reinforcing plate 7 are respectively provided with several ventilation holes to maintain stable air pressure during concrete pouring.

[0050] The upper reinforcing plate 6 is horizontal and fitted over the lower reinforcing ring plate 2, and welded to and fixed to the reinforcing ring plate 2 and the steel pipe column 1. The lower reinforcing plate 7 is horizontal and fitted over the steel pipe column 1, and welded to and fixed to the steel pipe column 1. Ten reinforcing ribs 8 are arranged between the upper reinforcing plate 6 and the lower reinforcing plate 7, and are symmetrically distributed on both sides of the steel pipe column 1 (5 ribs on each side). The upper edge of the reinforcing rib 8 is welded to the upper reinforcing plate 6, the lower edge of the reinforcing rib 8 is welded to the lower reinforcing plate 7, and the inner edge of the reinforcing rib 8 is welded to the reinforcing ring plate 2 and the steel pipe column 1. The edges of the reinforcing rib 8 are aligned with the upper reinforcing plate 6 and the lower reinforcing plate 7. The upper side of the reinforcing rib 8 is longer than the lower side, and the outer side is a straight line. The three types of plates are fixed to the steel pipe column 1, and the upper part is wider than the lower part, which can effectively bear the stress transmitted by the plate beam.

[0051] In addition, the space reserved on the upper side of the upper reinforcing plate 6 can be used to support the reinforcing bars of the plate beam and other force transmission mechanisms. The reinforcing bars of the plate beam should not be placed at the vent position to avoid blocking the vent.

[0052] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
