Description

Technical Field

[0001] The utility model belongs to the technical field of building steel structures, and in particular relates to an anchor steel-concrete beam structure device of a prefabricated pipe pile. Background Art

[0002] Existing prefabricated pipe pile connecting beams are mostly cast in concrete or welded with steel structure anchor rods, which have the following defects:

[0003] 1. If the prefabricated pipe pile connection beam is made of concrete, the pouring volume required to achieve the construction strength is large. After the pouring is completed, it cannot be guaranteed that the joint surface of the prefabricated pipe pile and the concrete are tightly combined as one, which will weaken the connection strength. More importantly, when pouring concrete, the ends of the prefabricated pipe piles need to be roughened before connection. The roughening of the ends of the prefabricated pipe piles will reduce the prestressed protective layer of the steel bars in the pipe piles, affecting the structural strength, and it is easy to form stress damage at the roughening place;

[0004] 2. If the prefabricated pipe pile connecting beam adopts steel structure welded anchor rod, it is necessary to drill holes in the steel structure when connecting the steel structure and the anchor rod. It is difficult to drill holes in the steel structure. At the same time, drilling holes will weaken the strength of the steel structure. Utility Model Content

[0005] The utility model aims to solve the technical problems existing in the background technology and provides an anchor steel-concrete beam structure device of a prefabricated pipe pile, in which two H-shaped steels are cast into an integrated steel-concrete structure through an anchor concrete block in the middle, and the anchor is installed in the anchor concrete block in the middle, thereby avoiding the defects of using concrete casting alone or steel structure welding anchor alone, and combining the advantages of the two structures. The structural strength of the whole device can meet the construction requirements, and it is easy to install and disassemble.

[0006] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:

[0007] A prefabricated pipe pile anchor steel-concrete beam structure device comprises a prefabricated pipe pile and an anchor steel-concrete beam structure, wherein the anchor steel-concrete beam structure comprises a steel-concrete structure and an anchor;

[0008] The steel-concrete structure comprises a first H-shaped steel, an anchor concrete block and a second H-shaped steel, wherein the first H-shaped steel and the second H-shaped steel are connected by pouring the anchor concrete block in the middle to form an integrated steel-concrete structure, and the outer ends of the first H-shaped steel and the second H-shaped steel are connected to the prefabricated pipe piles through arc-shaped connecting steel plates;

[0009] One end of the anchor rod is installed in the anchor rod concrete block of the steel-concrete structure.

[0010] Furthermore, the outer ends of the first H-shaped steel and the second H-shaped steel are connected to the arc-shaped connecting steel plate by bolts, and the arc-shaped connecting steel plate is connected to the prefabricated pipe pile by welding or bolts.

[0011] Furthermore, the arc-shaped connecting steel plate is a U-shaped structure, including a central arc plate and two side plates;

[0012] The two side plates are provided with oblong holes.

[0013] Furthermore, a mounting pipe is pre-buried in the anchor concrete block, and after the anchor concrete block is formed, the anchor rod is installed and connected through the pre-buried mounting pipe by welding or threaded connection.

[0014] Furthermore, the anchor rod is installed perpendicularly to the horizontal axis of the anchor rod concrete block and tilted downward.

[0015] Furthermore, the steel-concrete structure has a plurality of steel bars pre-embedded and cast at the middle anchor concrete block, and both ends of the steel bars extend to the first H-shaped steel and the second H-shaped steel respectively, and partially overlap with the first H-shaped steel and the second H-shaped steel in the length direction.

[0016] Furthermore, the first H-shaped steel and the second H-shaped steel on both sides of the anchor concrete block are cast with H-shaped steel concrete.

[0017] Furthermore, the side of the anchor concrete block close to the supporting soil body is the front side;

[0018] On the front side of the anchor concrete block, the first H-shaped steel and the second H-shaped steel are reinforced and connected by a connecting steel plate; or, on the front and rear sides of the anchor concrete block, the first H-shaped steel and the second H-shaped steel are reinforced and connected by a connecting steel plate.

[0019] Furthermore, a weakening hole is opened in the middle of the connecting steel plate.

[0020] Furthermore, in the steel-concrete structure, the webs of the two left and right H-shaped steels are installed and placed horizontally.

[0021] Compared with the prior art, the beneficial effects produced by the utility model are:

[0022] (1) The steel-concrete structure casts and connects the steel structure and the concrete structure into an integrated structure, which can avoid the disadvantage of a large concrete casting volume required when a concrete casting structure is used alone; at the same time, since the prefabricated pipe piles and the H-shaped steel of the steel-concrete structure are connected by an arc-shaped connecting steel plate, the defect that the ends of the prefabricated pipe piles need to be roughened and weakened in strength when a concrete casting structure is used alone is avoided; moreover, the anchor rods are installed in the anchor rod concrete blocks of the steel-concrete structure, which makes installation more convenient, and avoids the defect that when an anchor rod is used alone to connect the steel structure, it is necessary to drill holes in the steel structure, which makes drilling difficult and weakens the strength of the steel structure;

[0023] (2) Several steel bars are pre-embedded and cast at the anchor concrete block to strengthen the casting connection strength; and H-shaped steel concrete can also be cast at the H-shaped steel on both sides of the anchor concrete block to better cast and connect the H-shaped steel, steel bars and anchor concrete block into an integrated structure, thereby increasing the structural strength of the entire device and achieving a better support effect;

[0024] (3) The first H-shaped steel and the second H-shaped steel can be reinforced and connected by a connecting steel plate at the casting connection, further increasing the structural strength of the entire device; at the same time, a weakening hole can be opened in the middle of the connecting steel plate, so that the stress weak point of the entire steel-concrete structure occurs at the anchor concrete block which is more convenient to disassemble and maintain, making it easier to disassemble and maintain;

[0025] (4) The anchor rod is installed vertically and tilted downwardly to the horizontal axis of the anchor rod concrete block, making full use of the fact that the compressive strength of the concrete casting structure is better than its tensile strength. The entire device can withstand greater forces and achieve better support effects.

[0026] (5) The arc-shaped connecting steel plate is a U-shaped structure, and oblong holes are installed on its two side plates, which facilitate the adjustment of installation size errors with the H-shaped steel at both ends of the steel-concrete structure through bolt connection. At the same time, the use of bolt connection facilitates the subsequent disassembly and reuse of the steel-concrete structure;

[0027] (6) The webs of the left and right H-shaped steels in the steel-concrete structure are installed horizontally, which is conducive to pre-bending the two H-shaped steels horizontally when the left and right prefabricated pipe piles are tilted or misaligned, thereby making it easier to assemble and connect the steel-concrete structure with the left and right prefabricated pipe piles.

[0039] Example 1

[0040] Combination Figure 1-5 As shown, the embodiment of the utility model provides an anchor steel-concrete beam structure device of a prefabricated pipe pile, comprising a prefabricated pipe pile 1 and an anchor steel-concrete beam structure, wherein the anchor steel-concrete beam structure comprises a steel-concrete structure 3 and an anchor 2;

[0041] The steel-concrete structure 3 comprises a first H-shaped steel 3.1, an anchor concrete block 3.2 and a second H-shaped steel 3.3. The first H-shaped steel 3.1 and the second H-shaped steel 3.3 are cast and connected to form an integrated steel-concrete structure 3 through the middle anchor concrete block 3.2. The outer ends of the first H-shaped steel 3.1 and the second H-shaped steel 3.3 are connected to the prefabricated pipe pile 1 through an arc-shaped connecting steel plate 5.

[0042] One end of the anchor rod 2 is installed in the anchor rod concrete block 3 . 2 of the steel-concrete structure 3 .

[0043] Specifically, the outer ends of the first H-shaped steel 3.1 and the second H-shaped steel 3.3 are connected to the arc-shaped connecting steel plate 5 by bolts, so as to facilitate subsequent disassembly.

[0044] The arc-shaped connecting steel plate 5 is connected to the prefabricated pipe pile 1 by welding or bolts.

[0045] One end of the anchor rod 2 is installed in the anchor rod concrete block 3.2 of the steel-concrete structure 3. Specifically, a mounting pipe can be pre-buried in the anchor rod concrete block 3.2. After the anchor rod concrete block 3.2 is formed, the anchor rod 2 is installed and connected through the pre-buried mounting pipe by welding or threaded connection, thereby avoiding the difficulty of drilling a hole in the steel structure and weakening the strength of the steel structure when the anchor rod is connected to the steel structure.

[0046] The above-mentioned casting connection of the steel structure and the concrete structure into an integrated structure can avoid the disadvantage of a large concrete casting volume required when a concrete casting structure is used alone; at the same time, since the prefabricated pipe piles and the H-shaped steel of the steel-concrete structure are connected by an arc-shaped connecting steel plate, the defect that the ends of the prefabricated pipe piles need to be roughened to weaken the structural strength when a concrete casting structure is used alone is avoided; moreover, the anchor rods are installed in the anchor rod concrete blocks of the steel-concrete structure, which is more convenient to install, avoiding the defect that when an anchor rod is used alone to connect the steel structure, it is necessary to drill a hole in the steel structure, which makes drilling difficult and weakens the strength of the steel structure.

[0047] In addition, the steel-concrete structure of the embodiment of the utility model is easy to disassemble and can be reused. After the support is completed, the entire steel-concrete structure can be reused by disassembling the arc-shaped connecting steel plate and the two ends of the steel-concrete structure, cutting off or disassembling the anchor rods. If necessary, the middle anchor rod concrete block 3.2 can also be knocked out with a special tool, and the steel-concrete structure of a new size and length can be recast for reuse.

[0048] Example 2

[0049] The present invention has made the following improvements on the basis of the first embodiment:

[0050] The steel-concrete structure 3 has a plurality of steel bars 4 pre-embedded and cast at the middle anchor concrete block 3.2, and both ends of the steel bars 4 extend to the first H-shaped steel 3.1 and the second H-shaped steel 3.3 respectively, and partially overlap with the first H-shaped steel 3.1 and the second H-shaped steel 3.3 in the length direction.

[0051] The purpose of such arrangement is: by pre-embedding and casting a number of steel bars 4 in the anchor concrete block 3.2, the strength of the casting connection can be strengthened, the structural strength of the entire device can be increased, and a better supporting effect can be achieved.

[0052] Furthermore, the first H-shaped steel 3.1 and the second H-shaped steel 3.3 on both sides of the anchor concrete block 3.2 are also cast with H-shaped steel concrete 6 (see Figure 2 As shown), the H-shaped steel, steel bars and anchor concrete blocks can be better poured and connected into an integrated structure.

[0053] Example 3

[0054] The present invention has made the following improvements on the basis of Embodiment 1 or 2:

[0055] The side of the anchor concrete block 3.2 close to the supporting soil body is the front side.

[0056] See also Figure 6As shown, at the front side of the anchor concrete block 3.2, the first H-shaped steel 3.1 and the second H-shaped steel 3.3 are reinforced and connected by an external connecting steel plate 7, so as to further increase the structural strength of the whole device.

[0057] In some other embodiments, to meet higher structural strength requirements, such as Figure 7 As shown, at the front and rear sides of the anchor concrete block 3.2, the first H-shaped steel 3.1 and the second H-shaped steel 3.3 are reinforced and connected by an external connecting steel plate 7.

[0058] In some other embodiments, a weakening hole may be provided in the middle of the outer connecting steel plate 7 so that the stress weak point of the entire steel-concrete structure occurs at the anchor concrete block 3.2 which is more convenient for disassembly and maintenance, making disassembly and maintenance more convenient.

[0059] Example 4

[0060] The present utility model embodiment has made the following improvements on the basis of any one of the embodiments 1-3:

[0061] like Figure 3-4 As shown, the anchor rod 2 is installed obliquely downwardly and perpendicularly to the horizontal axis of the anchor rod concrete block 3.2.

[0062] The purpose of such arrangement is to make full use of the characteristic that the compressive performance of the cast concrete structure is better than the tensile performance. The anchor rod 2 is installed obliquely downward, so that the anchor rod 2 can apply an oblique downward force to the anchor rod concrete block 3.2. The whole device can withstand a greater force and achieve a better support effect.

[0063] Example 5

[0064] The present utility model embodiment has made the following improvements on the basis of any one of the embodiments 1-4:

[0065] like Figure 4-5 As shown, the arc-shaped connecting steel plate 5 is a U-shaped structure, including a middle arc plate and two side plates. The two side plates are provided with oblong holes, which is convenient for adjusting the installation size error through the oblong holes when the H-shaped steel at both ends of the steel-concrete structure are connected by bolts, and the installation is more convenient and efficient. At the same time, the bolt connection is convenient for the subsequent disassembly of the steel-concrete structure for reuse.

[0066] Example 6

[0067] The present utility model embodiment has made the following improvements on the basis of any one of the embodiments 1-5:

[0068] like Figure 4-5 As shown, in the steel-concrete structure 3, the webs of the two left and right H-shaped steels are installed and placed horizontally.

[0069] The purpose of this arrangement is: when the anchor steel-concrete beam structure device of the prefabricated pipe piles is assembled, the left and right prefabricated pipe piles may tilt toward the inner side close to the supporting soil body or the outer side away from the supporting soil body when they are lowered, resulting in misalignment. At this time, the existing hydraulic H-beam bending machine can be used to pre-bend the left and right H-beams of the steel-concrete structure 3, so that the steel-concrete structure 3 is easier to connect with the two misaligned left and right prefabricated pipe piles; the embodiment of the utility model installs and places the webs of the left and right H-beams in the steel-concrete structure 3 horizontally, so that the left and right flange plates of the H-beam are placed vertically. Compared with the vertical placement of the web of the H-shaped steel and the horizontal placement of the left and right flange plates, the former is easier to pre-bend the H-beam in the horizontal direction, and the installation operation is more convenient and efficient.

[0070] The above description is only an embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the scope of application of the present invention shall be included in the protection scope of the present invention.
