Description

Technical Field

[0001] This utility model relates to a quick-installation and dismantling formwork system for pipe well structural columns, belonging to the field of pipe well structural column construction technology. Background Technology

[0002] As is generally known, a pipe shaft is a vertical shaft in a building used to house vertical equipment pipelines. The more complex and advanced the building, the more support systems it needs. In addition to basic water supply, power supply, and drainage pipelines, it also needs functions such as telephone, cable TV, monitoring, and ventilation.

[0003] Currently, in some building pipe shafts, such as when installing fire protection, smoke exhaust, and ventilation pipes, it is necessary to install the pipes first, and then carry out the masonry of the pipe shaft walls and the pouring of structural columns and ring beams.

[0004] Because the distance between the manhole wall and the pipe wall is small after the pipeline is installed, personnel cannot enter the manhole to carry out formwork work. Therefore, there is an urgent need for a structural column formwork system that can be installed and dismantled without entering the manhole. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a quick-installation and dismantling formwork system for pipe well structural columns. This formwork system can overcome the difficulties in formwork construction caused by the small distance between the pipe well wall and the pipe wall, and can conveniently and efficiently install and dismantle the pipe well structural column formwork after the pipe is installed.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A quick-installation and dismantling formwork system for pipe well structural columns, comprising:

[0008] The internal template structure is mainly composed of multiple internal template units spliced ​​together end to end along the depth direction of the pipe well.

[0009] The external formwork structure is mainly composed of multiple external formwork units spliced ​​together end to end along the depth direction of the pipe well.

[0010] The template reinforcement structure mainly consists of multiple template reinforcement components arranged along the depth direction of the pipe well. Each template reinforcement component is detachably connected to the inner template unit and the outer template unit at the same height at both ends.

[0011] The formwork construction structure is mainly composed of multiple tie rod and pin assemblies assembled end to end along the depth direction of the pipe well.

[0012] Each tie rod and pin assembly includes a tie rod portion and a pin portion. Both ends of the tie rod portion are provided with connecting portions for assembly. The pin portion is laterally connected to one side of the tie rod portion and is configured to detachably connect the inner template unit and the template reinforcement at the corresponding position. A limiting portion is also provided on one side of the top of the tie rod portion, which is configured to limit the axial displacement of the assembled pin portion.

[0013] As a further optional design of this technical solution, the template reinforcement component includes several reinforcing tabs, one end of which is connected to the middle of the corresponding inner template unit, and the other end is connected to multiple splicing parts of the corresponding outer template unit.

[0014] As a further optional design of this technical solution, the splicing part of the outer template unit is configured as a first splicing pin hole opened on the outer template unit, and adjacent outer template units are connected together by a first pin in the first splicing pin hole.

[0015] As a further optional design of this technical solution, the top center of the inner template unit is provided with vertically intersecting pull tab grooves and connecting pin holes. The pull tab grooves are configured to allow the ends of the corresponding reinforcing pull tabs to be inserted, and the connecting pin holes are configured to cooperate with the pin parts for connection.

[0016] Multiple second splicing pin holes are provided at both ends of the inner template unit, and adjacent inner template units are connected together by second pins through the second splicing pin holes.

[0017] As a further optional design of this technical solution, the limiting part is configured as a pin hole opened in the tie rod part, and the position of the pin hole corresponds to the bottom of the top of the spliced ​​inner template unit.

[0018] As a further optional design of this technical solution, the connecting part of the tie rod is configured as a threaded head, and two adjacent threaded heads are assembled together by a connecting nut.

[0019] As a further optional design of this technical solution, an elastic washer is also provided between the ends of two adjacent threaded heads.

[0020] As a further optional design of this technical solution, the pin part and the tie rod part are connected by a connecting piece, and the connecting piece is set between the corresponding connecting thread head and the corresponding pin hole.

[0021] With the above technical solution, this utility model provides a quick-installation and dismantling formwork system for pipe well structural columns. By setting up modular inner formwork structures, outer formwork structures, and formwork construction structures, and using a formwork reinforcement structure in the form of reinforcing tabs to connect the inner and outer formworks, especially by operating the formwork construction structure in the form of tie rod pin components outside the well, the assembled inner formwork structure can be placed as a whole in the pipe well first, and then the inner and outer formworks can be installed and dismantled between the pipe well and the pipe well wall. This overcomes the difficulties in formwork construction caused by the small distance between the pipe well wall and the pipe wall, making it more convenient and efficient.

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0048] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0049] In the description of this utility model, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] Figures 1 to 9 A schematic diagram of a preferred embodiment of the present invention is shown. Figure 1 A quick-installation and dismantling formwork system 50 for pipe well structural columns includes an inner formwork structure 51, an outer formwork structure 52, a formwork reinforcement structure 53, and a formwork construction structure 54. (Refer to...) Figure 2 The inner template structure 51 is mainly composed of multiple inner template units 511 spliced ​​end to end along the depth direction of the pipe well 20; refer to Figure 5 The outer formwork structure 52 is mainly composed of multiple outer formwork units 521 spliced ​​end to end along the depth direction of the pipe well 20; refer to Figure 1 and 2 The template reinforcement structure 53 mainly consists of multiple template reinforcement components 531 arranged along the depth direction of the pipe well 20. Each template reinforcement component 531 is detachably connected at both ends to an inner template unit 511 and an outer template unit 521 at the same height. (Refer to...) Figure 1 and 2 The formwork construction structure 54 is mainly composed of multiple tie rod and pin assemblies 541 assembled end to end along the depth direction of the pipe well 20; refer to Figure 2 and Figure 3 Each tie rod pin assembly 541 includes a tie rod portion 5411 and a pin portion 5412. Both ends of the tie rod portion 5411 are provided with connecting portions 5411-1 for assembly. The pin portion 5412 is laterally connected to one side of the tie rod portion 5411. The pin portion 5412 is configured to detachably connect the inner template unit 511 at the corresponding position to the template reinforcement member 531. A limiting portion 5411-2 is also provided on one side of the top end of the tie rod portion 5411. The limiting portion 5411-2 is configured to limit the axial displacement of the assembled pin portion 5412.

[0052] In this embodiment, both the inner template structure 51 and the outer template structure 52 adopt modularly designed metal templates, and are divided into a bottom template and a standard template. (Refer to...) Figure 2 and Figure 4 The inner template unit 511 includes multiple standard inner templates 5111 and one bottom inner template 5112. The bottom inner template 5112 has the same structure as the standard inner templates 5111, differing only in length. The standard inner templates 5111 are connected to each other and to the bottom inner template 5112 using pins. (Refer to...) Figure 5 and Figure 6 The outer template unit 521 includes multiple standard outer templates 5211 and a bottom outer template 5212. The bottom outer template 5212 has the same structure as the standard outer template 5211, except for the length. The standard outer templates 5211 are also spliced ​​together by pins as well as between the standard outer templates 5211 and the bottom outer template 5212.

[0053] Reference Figure 3 In this embodiment, the assembled template construction structure 54 is combined with the inner template structure 51 using pins 5412. Simultaneously, one end of the template reinforcement structure 53, placed on the inner template structure 51, is fixed, while the other end of the template reinforcement structure 53 is fixedly connected at the joint of the outer template structure 52. After the entire manhole structural column template system 50 is assembled, the axial displacement of the template construction structure 54 is locked by the limiting part 5411-2, after which the pouring of the manhole structural column 40 can be carried out. When disassembly is required, the template construction structure 54 is also operated; first, the inner template structure 51 is disassembled from the template reinforcement structure 53, and then the inner template structure 51 is moved out as a whole.

[0054] Therefore, in specific implementation, refer to Figure 1 The template construction structure 54 allows for convenient and efficient assembly of the assembled inner template structure 51 with the outer template structure 52 inside the pipe well 20 via the template reinforcement structure 53. It also allows for convenient and efficient dismantling and removal of the assembled inner template structure 51 within the pipe well 20.

[0055] Furthermore, during the assembly and disassembly process, to facilitate the operation of the formwork construction structure 54, refer to... Figure 2 A lever handle can be installed on the lever part 5411 of the top lever pin assembly 541.

[0056] Reference Figure 3 and Figure 9For example, the template reinforcement component 531 in this embodiment of the present invention may include a plurality of reinforcing tabs 5311, one end of the plurality of reinforcing tabs 5311 being connected to the middle of the corresponding inner template unit 511, and the other end being connected to a plurality of splicing parts of the corresponding outer template unit 521.

[0057] More specifically, refer to Figure 9 The number of reinforcing tabs 5311 can be three, namely horizontal tab 5311-1, vertical tab 5311-2 and diagonal tab 5311-3, which are respectively connected to the three first splicing pin holes 521-1 on the outer template unit 521 for all-round reinforcement of the inner and outer templates.

[0058] In practice, each reinforcing tab 5311 is inserted into the corresponding tab groove 511-1 from the outside and aligned with the first splicing pin hole 521-1 of the outer template structure 52. The template construction structure 54 is lifted by rotating the entire structure, so that the pin parts 5412 of all the tie rod pin assemblies 541 are aligned with the corresponding connecting pin holes 511-2 on the inner template structure 51. Then, the template construction structure 54 is pressed down as a whole, so that the pin parts 5412 are inserted into the connecting pin holes 511-2. Finally, a pin is installed on the limiting part 5411-2 of the template construction structure 54 to prevent it from being pulled out.

[0059] Reference Figure 5 and Figure 6 For example, in this embodiment of the present invention, the splicing part of the outer template unit 521 can be configured as a first splicing pin hole 521-1 opened on the outer template unit 521, and adjacent outer template units 521 are connected together by a first pin 521-1-1 in the first splicing pin hole 521-1.

[0060] In specific implementation, multiple sets of evenly distributed first splicing pin holes 521-1 are opened at the splicing point of the outer template unit 521, and the first pin 521-1-1 is used to realize the pin connection. For axial positioning, the first pin 521-1-1 is generally a pin with a pin plate.

[0061] Reference Figure 4 For example, in the embodiment of the present invention, the top center of the inner template unit 511 is provided with a vertically intersecting pull tab groove 511-1 and a connecting pin hole 511-2. The pull tab groove 511-1 is configured to allow the end of the corresponding reinforcing pull tab 5311 to be inserted, and the connecting pin hole 511-2 is configured to cooperate with the pin part 5412. Both ends of the inner template unit 511 are provided with a plurality of second splicing pin holes 511-3. Adjacent inner template units 511 are connected together by second pins 511-3-1 in the second splicing pin holes 511-3.

[0062] In specific implementation, multiple sets of evenly distributed second splicing pin holes 511-3 are opened at the splicing points of the inner template unit 511, and the pin connection is achieved by using the second pin 511-3-1. The second splicing pin hole 511-3 located in the middle position serves as the connecting pin hole 511-2 for connection with the template construction structure 54.

[0063] Reference Figure 2 For example, in this embodiment of the present invention, the limiting part 5411-2 is configured to be opened in the pin hole 5411-2-1 of the pull rod part 5411, and the position of the pin hole 5411-2-1 corresponds to the bottom of the top of the spliced ​​inner template unit 511.

[0064] Reference Figure 8 More specifically, in this embodiment of the present invention, the pin portion 5412 and the pull rod portion 5411 can be connected by a connecting piece 5413, and the connecting piece 5413 is disposed between the corresponding connecting thread head 5411-1-1 and the corresponding pin hole 5411-2-1.

[0065] In use, after the entire assembly of the manhole structural column template system 50 is completed, the pin is inserted and positioned in the pin hole 5411-2-1 of the top tie rod part 5411. During specific assembly, the tie rod pin assembly 541 is moved down. When the pin part 5412 aligns with the pin hole 511-2, the position of the pin hole 5411-2-1 is exactly at the locking position below the template, thus allowing axial positioning using the pin.

[0066] Reference Figure 7 Specifically, in this embodiment of the present invention, the connecting part 5411-1 of the pull rod part 5411 can be configured as a connecting thread head 5411-1-1, and two adjacent connecting thread heads 5411-1-1 are assembled together by connecting nuts 5411-1-2.

[0067] When assembling the template construction structure 54, the connection thread head 5411-1-1 and the connection nut 5411-1-2 are used to splice two adjacent tie rod pin assemblies 541.

[0068] Also refer to Figure 7 Preferably, in this embodiment of the present invention, an elastic washer 5411-1-3 may be provided between the ends of two adjacent connecting threaded heads 5411-1-1.

[0069] More specifically, the elastic gasket 5411-1-3 can be an elastic rubber gasket. In specific implementation, elastic gaskets 5411-1-3 are set between the tie rod parts 5411 to facilitate adjustment of the rotation angle of two adjacent tie rod pin assemblies 541, so that the pin part 5412 on each tie rod pin assembly 541 maintains a consistent angular position, thereby accurately aligning with the inner template unit 511 in the same position.

[0070] Reference Figure 1 The present invention provides a quick-installation and dismantling pipe well structural column formwork system 50, the installation and use of which are as follows:

[0071] First, install the pipe 10 inside the pipe shaft 20, and then construct the pipe shaft wall 30. After the pipe shaft wall 30 is constructed, assemble the inner formwork structure 51 and the formwork construction structure 54 according to the wall height. Test insert the assembled inner formwork structure 51 and the assembled formwork construction structure 54. After the test insert is successful, place the assembled inner formwork structure 51 into the pipe shaft 20 from the top. Next, insert the formwork reinforcement 531 into the inner formwork structure 51 from the outside, and connect them through the pin part 5412 of the formwork construction structure 54. Finally, install pins at the limiting part 5411-2 at the top of the formwork construction structure 54 to prevent it from being pulled out. Then, assemble the outer formwork unit 521 from bottom to top with pins, and insert the formwork reinforcement 531 between adjacent outer formwork units 521. At this point, the installation of the pipe shaft structural column formwork system 50 is completed, and concrete pouring can begin.

[0072] This utility model provides a quick-installation and dismantling pipe well structural column formwork system 50, the dismantling process of which is as follows:

[0073] After the formwork system 50 of the pipeline well is ready for dismantling, first remove the pins of the limiting part 5411-2; then lift the formwork construction structure 54 as a whole, so that the pins 5412 of the tie rod pin assembly 541 are all disengaged from the connecting pin holes 511-2; then move the inner formwork structure 51 laterally, so that the formwork reinforcement 531 is disengaged from the formwork; then the entire inner formwork structure 51 can be lifted out of the pipeline well 20; the dismantling of the outer formwork structure 52 can be done by removing the pin connections in sequence, and finally the formwork reinforcement 531 on the outer side is cut off with a cutting machine.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
