Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to a multifunctional pier support system and construction method. Background Technology

[0002] The pier cap is mainly tied with thin iron wire by welding upright steel bars or angle steel to form a support frame, and then the pier cap steel bars are tied to the support frame. When the pier cap is poured with concrete, the upright steel bars are embedded in the concrete along with the stressed steel bars.

[0003] In existing technologies, the load-bearing capacity of the foundation is borne by concrete and reinforcing steel bars. The stirrups, besides providing support before construction, serve virtually no other function. For projects with a large number of foundations, especially railway projects where there are thousands, the sheer number necessitates tying the reinforcing steel bars for each foundation before construction. This not only wastes time but also significantly increases construction costs. In some projects, the cost of stirrup installation is not included in the bidding process, forcing the construction company to bear this expense, thus increasing their overall costs.

[0004] Furthermore, the current bridge abutment construction methods involve numerous construction steps, with poor quality and slow speed in the binding of thin iron wires. During construction, the connections between different steps are not tight. The abutment formwork has a single function, and the formwork needs to be connected with precision-rolled threaded steel bars, which prevents the formation of an integrated load-bearing system among the various load-bearing components. The pre-tied abutment reinforcement is used as a support for binding the pier body's embedded reinforcement, resulting in poor constraint of the abutment reinforcement on the pier body's embedded reinforcement, leading to significant deformation of the pier body's embedded reinforcement and making construction difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional pier cap support system and construction method to solve the problems mentioned in the background art.

[0014] Preferably, beam - slab connectors are arranged at both ends of the grid longitudinal beam. The beam - slab connector includes two "L" - shaped plates. The two "L" - shaped plates are connected by bolts. After connection, the two "L" - shaped plates are buckled above the side template, and a rib plate is provided on the surface of one "L" - shaped plate, and the rib plate abuts against the lower part of the beam rod of the grid beam.

[0015] Preferably, the construction platform includes a construction board. Two groups of guardrails are provided on the top surface of the construction board. The top of the guardrail is connected to the bottom surface of the handrail. Moreover, support rods are provided at the four corners of the bottom surface of the construction platform.

[0018] A construction method for a multi-functional bearing platform support includes the bearing platform support system as described above. The construction method includes the following steps:

[0019] After the excavation of the bearing platform foundation pit and the treatment of the pile head steel bars are completed, construct the cushion layer and bind the bottom steel bar mesh.

[0020] Install the socket support in the middle of the bottom steel bar mesh as a temporary support for the steel bar mesh.

[0029] It should be noted that the Chinese characters "拆除" in the original text are misspelled. It should be "拆除" which means "dismantle" or "remove". The translation has been made according to the correct understanding.This invention proposes a multifunctional pier cap support system and construction method that rationally optimizes pier cap formwork. It employs a combination of formwork and a steel structure grid beam system to form a complete set of tools. The side formwork of the pier cap serves as support for the top grid beam system, forming a reliable connection between the two. This provides lifting points for the pier cap reinforcement skeleton, replacing the erected reinforcement and holding the load-bearing reinforcement skeleton in place. The top grid beam system can also serve as a construction platform for pouring pier cap concrete. During concrete pouring, the reliable connection between the top grid beam system and the side formwork provides support for the side formwork, replacing the original tensioned threaded reinforcement between the formwork sections, and eliminating the need for local openings in the formwork. The top grid beam system also serves as a positioning, fixing, and support system for the pre-embedded reinforcement in the pier body, preventing deformation. A simple construction scaffolding platform can be erected using the grid beam system as a platform, facilitating pier body reinforcement construction and ensuring worker safety. The multifunctional pier cap formwork support system allows for rapid installation and dismantling, and reuse, effectively reducing pier cap construction costs. Attached Figure Description

In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.

[0045] Embodiment 1

[0046] Please refer to Figures 1-10 , the present invention provides a technical solution: a multi-functional bearing platform support system, the multi-functional bearing platform support system includes: a cushion layer 9, a bottom steel bar mesh 1 is arranged above the cushion layer 9, a socket support 2 is arranged above the bottom steel bar mesh 1, and a top steel bar grid 3 is arranged above the socket support 2; side templates 4, which are supported outside the bottom steel bar mesh 1, and a cross beam 5 is arranged above the side templates 4; pier body embedded steel bar frames 7, which are arranged above the cross beam 5, construction platforms 6 are arranged on both sides of the pier body embedded steel bar frames 7, and a concrete bearing platform 8 is formed by pouring below the cross beam 5;

[0047] Reasonably optimize the bearing platform template, adopt the combination of the template + steel structure cross beam system to form a complete set of tooling. Through the bearing platform side template as the support of the bearing platform top cross beam system, a reliable connection is formed between the two, providing lifting points for the bearing platform steel bar skeleton, replacing the erection steel bars, and pulling the bearing platform stress steel bar skeleton.

[0048] Embodiment 2

[0049] On the basis of Embodiment 1, in order to realize the construction of the bottom support structure, the bottom steel bar mesh 1 includes bottom transverse steel bars 101 and bottom vertical steel bars 102. There are multiple bottom transverse steel bars 101 and multiple bottom vertical steel bars 102. The multiple bottom transverse steel bars 101 are arranged side by side, and the multiple bottom vertical steel bars 102 are arranged side by side. The bottom transverse steel bars 101 and the bottom vertical steel bars 102 are vertically and crosswise distributed, and the nodes of the bottom transverse steel bars 101 and the bottom vertical steel bars 102 are tied with steel wires, and both the bottom transverse steel bars 101 and the bottom vertical steel bars 102 are in a "C" - shaped structure; the socket support 2 includes two rows of vertical support frames 201. There are multiple in each row of vertical support frames 201. A transverse connecting rod 202 is arranged between every two vertical support frames 201 in each row. A first cross beam 203 is arranged between the two rows of vertical support frames 201, and a diagonal brace 204 is arranged between adjacent two vertical support frames 201. The top end of the vertical support frame 201 is provided with a support plate 205, and the support plate 205 is in a "C" - shaped plate structure;

[0050] The temporary support system is erected using a disc - and - socket support. The spacing of the vertical poles is reasonably set according to the size of the bearing platform. It is recommended that the standard step distance of the vertical poles be 1.8 m to 3 m, and the height is adjusted by the top bracket. When the height of the support is relatively high and problems such as tipping over may occur, short steel bars can be welded on the bottom steel mesh, and the vertical poles can be nested on the short steel bars and temporarily fixed; when the height of the support is relatively small, it can also be directly placed on the concrete cushion. During demolition, it can be directly pulled out from the top steel mesh. If the spacing of the steel bars is too small to be pulled out, a ladder can be used to enter the steel reinforcement cage for demolition; when tying the upper thin iron wire, about 0.5 m of steel bars are left un - tied to facilitate the later demolition of the support. After the support is demolished, it is immediately tied up.

[0051] Embodiment Three

[0052] On the basis of Embodiment Two, in order to realize the construction of the top steel bar grid 3, the top steel bar grid 3 includes multiple top horizontal stirrups 301 and multiple top vertical stirrups 302. The top horizontal stirrups 301 are in a "U" - shaped structure, and the top vertical stirrups 302 are in an annular structure. The top horizontal stirrups 301 include two groups, and the two groups of top horizontal stirrups 301 are cross - distributed. The top vertical stirrups 302 surround the outside of the two cross - distributed groups of top horizontal stirrups 301, and the nodes of the top horizontal stirrups 301 and the top vertical stirrups 302 are tied with thin iron wire;

[0053] When tying the upper steel mesh, the erection order of the steel bars is appropriately adjusted. The horizontal steel bars at the top of the support are directly supported on the top brackets of the support and slightly fixed, then the longitudinal steel bars are erected, and finally the remaining horizontal steel bars are erected on the longitudinal steel bars. The steel bars in the support and the top brackets of the support together serve as a temporary support system, and the steel bar nodes are quickly fixed with thin iron wire.

[0054] Embodiment Four

[0055] On the basis of Embodiment Three, in order to realize the construction of the side formwork 4, multiple side formworks 4 are provided. Angle steels 401 are provided on both sides of the side formworks 4. Adjacent two side formworks 4 are connected by bolts through the angle steels 401, and multiple side formworks 4 enclose a square frame. Multiple horizontally arranged horizontal secondary ribs 402 are provided on the surface of the side formworks 4, and multiple vertical main ribs 403 are provided on the surface of the side formworks 4;

[0056] The template width is divided into two sizes: a 1.5m wide standard template and a 0.5m wide spliced ​​template; the 1.5m wide standard template is 0.2m higher than the foundation, with a height of 2.2m, and the vertical main ribs are designed to be 5-10cm lower than the top of the template. The top horizontal secondary ribs and vertical main ribs are made of 100*100*5mm square tubing, while the remaining horizontal secondary ribs are made of C100*50*4 channel steel. The spacing between the vertical main ribs is 50cm, and the spacing between the bottom three horizontal secondary ribs is 20cm, while the rest are 30cm. The advantage of this design is that it maintains the flexibility of the connection between the beams and the formwork. The connection slots between the beams and the side formwork are not affected by the vertical main ribs of the formwork and can move freely in the horizontal direction. The 0.5m wide splicing formwork design is the same as the 1.5m wide standard formwork except for the width. The formwork is connected by high-strength bolts, with one bolt between every two horizontal secondary ribs. The bolt specification is tentatively set at M16, but the specific specification should be calculated and determined based on the foundation dimensions, etc. Common angle steel is used for corner connections to achieve conversion. For non-right-angle corners, two strip steel plates can be welded together for quick connection.

[0057] Example 5

[0058] Based on Embodiment 4, in order to realize the construction of the grid beam 5, the grid beam 5 includes multiple grid longitudinal beams 501 and multiple grid horizontal beams 502. There are multiple sets of grid horizontal beams 502. Two adjacent grid horizontal beams 502 in each set are connected by beam body connectors 503. The beam body connectors 503 are in the shape of an "I" and have a through hole reserved in the middle. The grid longitudinal beams 501 pass through the through hole, and the grid horizontal beams 502 are inserted into the slots on both sides of the beam body connectors 503 and fixed by bolts. Both ends of the grid longitudinal beams 501 are provided with beam plate connectors 504. The beam plate connectors 504 include two "L" shaped plates. The two "L" shaped plates are connected by bolts. The two "L" shaped plates are attached to the top of the side template 4 after connection. The surface of one "L" shaped plate is provided with a rib plate, which abuts against the bottom of the beam of the grid beam 5.

[0059] Considering the characteristics of foundation construction, this waffle slab system adopts a unique design approach, and the main design concept is determined based on the following requirements:

[0060] 1) The grid beams require rapid installation and segmented hoisting;

[0061] 2) The longitudinal and transverse beams of the grid beam can be moved relative to each other to avoid interference with the steel reinforcement or the vertical main beams of the side formwork;

[0062] 3) The grid beams meet the requirements for load-bearing capacity and stability;

[0063] 4) Requirements for quickly erecting and fixing the pier reinforcement using a grid beam as a support system;

[0064] 5) The requirement for quick and convenient removal of the grid beams after the foundation construction;

[0065] 6) Meet the requirements for flat joints between longitudinal and transverse beams.

[0066] 7) Requirements for rapid transportation and reuse of grid beams.

[0067] The cross-sectional dimensions of the longitudinal and transverse beams are tentatively set as 160*80*5mm; the steel plate thickness of the connecting node is 8-10mm, the width is 10cm, the angle steel is 50*4mm, and the channel steel is the same as the template on the same side.

[0068] The connection nodes between the longitudinal and transverse beams are refined according to the overall design concept to meet the following requirements:

[0069] 1) The spacing between longitudinal and transverse beams should be controlled within 1.2m, which can effectively reduce the beam cross-sectional dimensions;

[0070] 2) According to the requirement of parallel connection of longitudinal and transverse beams, one of the longitudinal beams or transverse beams must be broken. Since the transverse beam is the main load-bearing component, the longitudinal beam is broken here.

[0071] 3) Based on the requirements of rapid and convenient construction on site, the longitudinal and transverse beams should be connected in a way that allows them to move relative to each other but not to rotate.

[0072] 4) Although there are many bolts during assembly, they are basically standard components and do not affect the assembly speed.

[0073] After repeated comparisons and demonstrations, the following node configurations were adopted to achieve the functions required by the grid beam system.

[0074] The grid beam system provides tension to the steel reinforcement cage, thus supporting it. Suspension bars at the lifting points can be made from surplus steel rebar ends on-site, shaped into C- or Z-shapes. These should be fabricated and temporarily fixed according to the relative positions of the grid beam and the steel mesh. This method is relatively simple and reduces costs. After fixing the steel mesh, the lower support system can be removed, and the remaining upper steel reinforcement can be tied.

[0075] Example 6

[0076] On the basis of Embodiment 5, in order to realize the construction of the construction platform 6 and the embedded steel bar frame 7 of the pier body, the construction platform 6 includes a construction board 601. Two groups of guardrails 602 are arranged on the top surface of the construction board 601. The top ends of the guardrails 602 are connected to the bottom surface of the handrail. Support rods 604 are arranged at the four corners of the bottom surface of the construction platform 6. A connecting buckle plate 605 is arranged at the bottom surface of the support rod 604. The connecting buckle plate 605 is in the shape of a "C" - shaped plate structure. After the connecting buckle plate 605 is buckled on the grid - shaped cross beam 502, it is fixed by bolts. A plurality of ladders 603 arranged vertically are arranged between two of the support rods 604; The embedded steel bar frame 7 of the pier body includes a plurality of vertical steel bars 701. An annular stirrup 702 is sleeved outside the plurality of vertical steel bars 701. A plurality of annular stirrups 702 are provided. A clamping groove 703 in the shape of a "U" - shaped groove is opened on the inner ring surface of the annular stirrup 702. The vertical steel bar 701 is pushed into the clamping groove 703.

[0077] The embedded steel bars of the pier body are generally relatively high, and it is easy to produce large deformation during temporary fixation. Moreover, when installing, the steel bars are too long and not easy to fix. After analyzing and comparing multiple schemes, in this design, a steel platform is erected on the grid - shaped beam as the construction platform, and at the same time, it is used as the positioning and fixing device for the pier and platform steel bars, realizing the multi - functional use of the ladder. At the same time, the steel platform can be quickly expanded according to the actual situation on site to meet the operation requirements; In addition to setting the clamping grooves for the steel bars on the angle steel, adjusting clamping grooves for presetting the positions of the steel bars should be provided on both sides of the clamping groove to prevent the steel bars of the pier body from colliding with the steel bars of the bearing platform. The distance between the preset clamping grooves on each side and the steel bar clamping groove: when the steel bar spacing is 150 mm, it is required to be no more than 50 mm, as long as the steel bars do not collide after adjustment.

[0078] Embodiment 7

[0079] A multi - functional bearing platform support construction method includes the bearing platform support system as described above. This construction method includes the following steps:

[0080] After the bearing platform foundation pit is excavated and the pile head steel bars are processed, construct the cushion layer and bind the bottom steel bar mesh.

[0081] Install a socket support in the middle of the bottom steel bar mesh as a temporary support for the steel bar mesh.

[0082] After the installation of the temporary support is completed, start binding the top steel bar mesh of the bearing platform.

[0083] After the binding with fine iron wire is completed, loft again and install the side templates. The side templates can be pre - assembled and hoisted as a whole.

[0084] Install the steel grid - shaped cross beam system on the top of the bearing platform. Set hanging points on the cross beam, and the distance between the hanging points is not more than 1.2 m. After fixing the hanging points,拆除 the socket support system.

[0085] First, install the steel structure construction platform, then install the fixing and positioning angle steel, and finally install the pre-embedded steel bars in the pier body;

[0086] After the reinforcement of the pier body is installed and fixed, the temporary construction platform of the temporary pier body is removed, and the concrete of the pier cap can be poured.

[0087] Once the concrete of the foundation cap has cured to the required standard, the multi-functional foundation cap formwork support system can be removed.

[0088] For the construction of the pier body, this multi-functional pier cap formwork support system can be transported to the next pier cap for construction.

[0089] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
