Description

Technical Field

[0001] This utility model belongs to the technical field of building support beams and slabs, and particularly relates to a prefabricated building support beam and slab structure. Background Technology

[0002] The building support slab is a temporary support device that serves as the top beam of the building structure during the construction process. Its main structure includes a support frame and support beams supported by the support frame. The top beam slab is supported by the support beams and serves as a support structure. During the subsequent pouring of the building top beam, including the installation of steel cages, all construction is carried out on the top beam slab.

[0003] The prefabricated support top beam is a structure composed of multiple top beams combined to form a top beam structure of a certain area. It is matched with the size of the steel cage for subsequent construction. Therefore, a single top beam structure is an independent support unit. During construction, multiple top beam structures are often arranged in the length or width direction of the top beam.

[0004] Therefore, as an independent support unit, the stability of the top beam slab structure is the key factor determining the stability of the subsequent top beam slab support.

[0005] The stability of the supporting structure of the top beam slab, namely the supporting steel frame structure, is the key to determining the structural strength of the top beam slab unit, such as its load-bearing capacity. Currently, the supporting steel frame of the top beam slab uses multiple steel pipes as supports, and the steel pipes are connected by diagonal support rods.

[0006] However, in actual construction, the number of steel pipes supporting the bottom of the top beam is very large, resulting in a large number of diagonal support rods to be installed. The installation operation is too complicated, and subsequent disassembly is also very difficult.

[0007] Secondly, the stability of the inclined support rod is not high. The reason is that although the steel pipes are supported by the inclined support rod, they do not form an integrated tension structure. That is, the inclined support rod, as an inclined bracing structure, does not have high stability. When the construction area (or length) and weight of the building beam structure are large, the support structure cannot guarantee the safety of the support structure. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a prefabricated building support top beam plate structure.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A prefabricated building support beam-slab structure includes several cooperating beam-slab units, each beam-slab unit including a beam-slab, the bottom of which is supported by several support structures; each support structure includes a support beam supported at the bottom of the beam-slab, and several support frame structures are fixedly connected to the bottom of the support beam, each support frame structure including a support column, the support columns being anchored to each other by a tie-bracing structure;

[0011] The tie rod structure includes several upper tie rod plates and lower tie rod plates fixedly connected to the support column; it also includes several tie rod arm structures anchored to the upper tie rod plates and the lower tie rod plates of the adjacent support column respectively, and the tie rod arm structures can be tensioned.

[0012] Preferably, the top of the support column is welded with an installation structure for mounting support beams.

[0013] Preferably, the mounting structure includes a U-shaped steel, and the support beam is confined within the U-shaped steel;

[0014] The U-shaped steel is slidably connected to several fastening bolts that are fastened to the support beam.

[0015] Preferably, the longitudinal cross-sectional shape of the support beam is T-shaped;

[0016] The fastening screw passes through the waist of the support beam.

[0017] Preferably, the gantry arm structure includes an X-shaped connecting bracket located at the center of the gantry arm structure, and the X-shaped connecting bracket has four connecting ends;

[0018] The four connecting ends are threaded with a pair of upper pull arms located at the upper end and a pair of lower pull arms located at the lower end;

[0019] The upper and lower arms form an X-shaped structure.

[0020] Preferably, the upper pull plate and the lower pull plate are respectively provided with a plurality of anchoring holes, and anchor seats are hinged to the anchoring holes, and the upper pull arm and the lower pull arm are respectively anchored to the anchor seats.

[0021] Preferably, a hinge tongue is fixedly connected to the upper end of the upper pull arm;

[0022] The lower end of the pull-down arm is fixedly connected to a hinge tongue; the anchor seat is fixed in the anchor hole by a pin.

[0023] The outer end of the anchor seat is provided with a hinge interface, and the hinge tongue is hinged in the hinge interface by a pin.

[0024] Preferably, the lower end of the upper pull arm is tensioned to the X-shaped connecting bracket by a tensioning screw;

[0025] The upper end of the pull-down arm is tensioned to the X-shaped connecting bracket by a tensioning screw.

[0026] Preferably, the X-shaped connecting bracket has a threaded groove for threaded connection of the tensioning screw;

[0027] The upper and lower pull arms are limited to rotate and connected to the tensioning screw.

[0028] This utility model has the following beneficial effects:

[0029] 1. A tie-frame structure is used to anchor the support columns in all four directions (front, back, left, and right) of each support column as a base point. This structure forms an integrated tension structure for all top beam slab units, significantly improving the structural strength and support stability of the top beam slab units.

[0030] 2. The tie-frame arm structure includes an X-shaped connecting bracket located at the center of the tie-frame arm structure. The X-shaped connecting bracket has four connecting ends (one pair at the top and one pair at the bottom). Simultaneously, a pair of upper tie arms at the upper end and a pair of lower tie arms at the lower end are threaded onto the four connecting ends. Therefore, the upper and lower tie arms form an X-shaped structure. Specifically, the lower tie arms located diagonally are aligned with the upper tie arms. With this structure, adjacent support columns form a V-shaped traction structure through both the pair of upper and lower tie arms. Furthermore, the pair of diagonally positioned upper and lower tie arms provide diagonal traction. Therefore, the traction structure designed above offers very high traction stability, which is crucial for ensuring the structural strength of the top beam support during construction. At the same time, the stable support structure formed by this design effectively ensures construction safety.

[0031] 3. During operation, the tie-frame structure can be pre-assembled. The hinges at both ends of the upper and lower tie arms are aligned with the anchor seats on both sides. Then, the pins are inserted, and the free ends of the pins are tightened with nuts. This structural method enables rapid installation, greatly reducing the workload of supporting structure installation during the construction of the top beam. After installation, tensioning can be achieved by adjusting the tensioning screw. Tensioning can be performed after the depth of the upper thread groove of the X-shaped connecting bracket increases.

[0042] Example 1

[0043] like Figure 1-5As shown, a prefabricated building support top beam structure includes several cooperating top beam units, and the arrangement and installation method of the top beam units corresponds to the direction of the top beam structure.

[0044] Each top beam unit includes a top beam 1, and the bottom of the top beam 1 is supported by several supporting structures. During operation, the butt joints between the top beam 1s are ensured to be flush.

[0045] Meanwhile, the support structure includes a support beam 2 supported at the bottom of the top beam plate 1 (similar to the method disclosed in the prior art, the top beam plate 1 is fixedly installed on the support beam 2 by means such as screws). The support beam 2 is a conventional support beam 2 disclosed in the prior art, which is a T-shaped structural beam. Specifically, the top of the following support column is welded with an installation structure for mounting the support beam 2.

[0046] The installation structure includes a U-shaped steel 31 (the U-shaped steel 31 is welded and fixed to the top of the support column, and the bottom of the U-shaped steel 31 is welded to the support column through several triangular connecting ribs), and the support beam 2 is confined within the U-shaped steel 31.

[0047] Meanwhile, several fastening bolts 311 are slidably connected to the U-shaped steel 31 and fastened to the support beam 2. After passing through the waist of the support beam 2, the fastening bolts are tightened with nuts.

[0048] The support beam 2, which serves as the direct support structure, is installed in the manner described above.

[0049] In order to improve the structural support stability of the top beam 1 unit, the bottom of the above-mentioned support beam 2 is fixedly connected with several support frame structures (the support frame structures are distributed along the length of the support beam 2). The support frame structure includes support columns 3, and the support columns 3 are anchored to each other by tie rod structures 4.

[0050] Specifically, the tie structure 4 is used to anchor the support columns 3 in the four directions (front, back, left, and right) of each support column 3 as a base point. This structure enables all the top beam plate 1 units to form an integrated tension structure, which significantly improves the structural strength and support stability of the top beam plate 1 unit.

[0051] Example 2

[0052] like Figure 1-5As shown, based on the structure of Embodiment 1, the aforementioned tie rod structure 4 includes several upper tie rod plates 41 and lower tie rod plates 47 fixedly connected to the support column 3 (specifically, the upper tie rod plates 41 and lower tie rod plates 47 are spaced vertically apart, and the support column 3 is fixed by the support column 3 passing through the center of the upper tie rod plate 41 and the lower tie rod plate 47 and then welded). It also includes four tie rod arm structures anchored to the upper tie rod plate 41 and the adjacent lower tie rod plate 47 of the support column 3 respectively. Each tie rod arm structure anchors the support column 3 and the support columns 3 around its perimeter.

[0053] Specifically, the gantry arm structure includes an X-shaped connecting bracket 45 located at the center of the gantry arm structure. The X-shaped connecting bracket 45 has four connecting ends (one pair at the top and one pair at the bottom). Simultaneously, a pair of upper pull arms 43 located at the upper end and a pair of lower pull arms 44 located at the lower end are threadedly connected to the four connecting ends. Therefore, the upper pull arms 43 and lower pull arms 44 form an X-shaped structure. Specifically, the lower pull arms 44 located diagonally opposite to the upper pull arms 43 are aligned in a straight line.

[0054] Therefore, in the above structure, adjacent support columns 3 form a V-shaped traction structure through a pair of upper pull arms 43 and a pair of lower pull arms 44. Furthermore, the pair of upper pull arms 43 and lower pull arms 44 located diagonally provide oblique traction.

[0055] Therefore, the tension structure designed above exhibits extremely high stability during tensioning, which is crucial for ensuring the structural strength of the top beam support during construction. Simultaneously, the stable support structure formed by this design effectively guarantees construction safety.

[0056] Example 3

[0057] like Figure 1-5 As shown, in this embodiment, based on the structure of Embodiment 2, four circumferentially arrayed anchoring holes are respectively provided on the upper pull plate 41 and the lower pull plate 47. Anchor seats 42 are hinged to the anchoring holes, and the upper pull arm 43 and the lower pull arm 44 are respectively anchored to the anchor seats. A hinge tongue is welded and fixedly connected to the upper end of the upper pull arm 43; a hinge tongue is welded and fixedly connected to the lower end of the lower pull arm 44; the anchor seats are pinned in the anchoring holes by a pin; a hinge interface is provided at the outer end of the anchor seats, and the hinge tongue is hinged in the hinge interface by a pin.

[0058] Meanwhile, the tension arm structure can be tensioned. The lower end of the upper tension arm 43 is tensioned to the X-shaped connecting bracket 45 via a tensioning screw 46; the upper end of the lower tension arm 44 is also tensioned to the X-shaped connecting bracket 45 via a tensioning screw 46. Correspondingly, the X-shaped connecting bracket 45 has a threaded groove for threaded connection of the tensioning screw 46; the upper tension arm 43 and the lower tension arm 44 are rotatably connected to the tensioning screw 46. Specifically, according to the existing method, the end of the tensioning screw 46 is a T-shaped structure (the T-shaped structure of the limiting rotating head is a conventional limiting rotating connection structure disclosed in the prior art), and correspondingly, the upper tension arm 43 and the lower tension arm 44 have matching T-shaped limiting rotating grooves.

[0059] During operation, the tensioning screw 46 is fastened to the X-shaped connecting bracket 45. This structure enables operation and installation by tightening the tensioning screw 46 (for ease of tightening, the tensioning screw 46 has an integrally formed hexagonal protrusion 461).

[0060] In actual operation, the tie rod structure 4 can be pre-assembled, and the hinges at both ends of the upper tie arm 43 and lower tie arm 44 can be aligned with the anchor seats 42 on both sides. Then, the pin is inserted, and the free end of the pin is tightened and fixed with a nut. This structure enables rapid installation, greatly reducing the workload of supporting structure installation during the construction of the top beam. After installation, tensioning can be achieved by adjusting the tensioning screw 46. That is, after the depth of the upper thread groove of the X-shaped connecting bracket 45 is increased, the tensioning operation can be performed.

[0061] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
