Description

  The present invention relates to construction for installing water and water, ventilation pipes and the like in wall materials such as concrete, and in particular, pipes used when placing concrete to install pipes for passing water, air, etc. in the concrete. The present invention relates to an installation member.

  In a conventional concrete building structure, piping or a tubular penetrating frame material is used in advance in order to embed exhaust, water distribution, ventilation piping and the like in concrete. For example, a plate-shaped temporary frame (form frame) is installed along the vertical direction or the horizontal direction before placing concrete, and piping or the like is fixed between the temporary frames. After that, the concrete is placed and the temporary frame is removed after the concrete is solidified. Then, the pipe installed inside the concrete is connected to the external pipe.

As a pipe installation member, a pipe installation member using a spring or the like is known (see Patent Document 1). In Patent Document 1, a spring-type biasing mechanism for fixing the through-hole forming sleeve is provided. When described using the reference numerals used in Patent Document 1, the spring-type biasing mechanism (10) is an outer cylinder. A case (5), an inner cylinder case (6), an absorber (7), and a coil spring (8) are provided, and case covers (13) and (14) are mounted via joint pipes (11) and (12). (See paragraph [0017]). Furthermore, the spring-type urging mechanism (10) includes a bracket (28) as a locking mechanism, and when locked, the coil spring (8) is compressed and the cases (5) and (6) are in a contracted state (paragraph [0021] reference). When the sleeve outer body (3) is fixed to the beam formwork (P), the locked spring-type biasing mechanism (10) is mounted in the sleeve (3), and the sleeve (3) is fixed to a predetermined target. When moved to the position, the lock is released by operating the lock lever (30) (see FIGS. 4 and 5). By releasing the lock, the spring biasing mechanism (10) is extended by the restoring force of the coil spring (8). Accordingly, the sleeve outer body (3) expands, and the case lids (13) and (14) press against the inner surface of the mold P (see paragraphs [0029] and [0030]). Accordingly, the sleeve outer body (3) is positioned.
JP 09-4222 A

  In patent document 1, it is not comprised so that a hole may be provided and positioned in a temporary frame, but piping must be moved to the desired position using indicators, such as a mark. In addition, since the pipe (sleeve) is instantaneously extended by unlocking, the positioning cannot be performed accurately. Moreover, since it is the structure which pressure-contacts and positions a piping, a piping main body must be extensible. Therefore, when a pipe having a predetermined length is used, the spring-type biasing mechanism disclosed in Patent Document 1 cannot be used between temporary frames installed according to the length. Furthermore, since the spring-type urging mechanism of Patent Document 1 is configured in a size corresponding to the pipe length, the configuration becomes complicated and installation in the pipe becomes difficult.

  On the other hand, there is a method in which the frame material is moved to the position of a hole formed in the temporary frame in advance, a bolt or the like is passed through the hole from the outside of the temporary frame to the frame material center side, and the position of the frame material is fixed with a nut or the like. . However, the operation of fixing such pipes, frame members, etc. to the temporary frame requires a plurality of workers, and it is difficult to quickly move the pipes, frame members to the positions of the holes and position them.

  The pipe installation member of the present invention is a pipe installation member that can position pipes and frame materials easily and accurately without requiring a large number of workers, and improves the work efficiency of pipe installation. Concrete, mortar It is installed at the end of the pipe in order to install a pipe that allows fluid such as water and air to pass through the wall material. For example, in concrete placement, it is used to install a pipe between two temporary frames and is installed at both ends of the pipe. Here, the joint is defined as a part of the pipe even when the joint is attached to the pipe end as well as the pipe.

  The pipe installation member of the present invention is used when positioning a pipe between temporary frames installed according to a predetermined length of the pipe. The pipe installation member includes a main body having an end face facing the temporary frame, and an accommodation hole extending along the central axis direction of the pipe and having an opening formed on the temporary frame side. The end face of the main body may protrude from the opening face of the pipe end, or may be at the same position as the opening face or below (in the pipe). For example, when a flange is formed on the outer periphery of the main body, the end surface of the main body is the outermost side along the pipe length direction. On the other hand, for example, when the main body is screwed into the pipe end and inserted, the main body end face and the pipe end (the opening face thereof) are the same or the opening face of the pipe end is the outermost.

  The piping installation member extends to the temporary frame side along the accommodation hole, and a positioning member inserted into the hole of the temporary frame, and an urging member that has elasticity and urges the positioning member toward the temporary frame side Is provided. For example, the urging member and the positioning member may be directly or indirectly connected in order from the center of the pipe, or an urging member such as a coil spring may be provided around the positioning member. The urging member and the positioning member may be arranged so as to be operatively connected (so that a physical force acts on each other). As the biasing member, for example, a spring or rubber is applied, and as the positioning member, for example, a rigid member is applied.

  The pipe installation member further includes a stopper that can move relative to the main body so as not to protrude from the end or end face of the pipe toward the temporary frame, and that can close the opening and lock the positioning member. . The stopper moves so as not to exceed the end face when the end face of the main body protrudes to the temporary frame side from the pipe end. On the other hand, if the end face is located below the pipe end, it does not exceed the pipe end. To move. Regarding the movement of the stopper, for example, it may be configured to slide along the end face or the pipe end (opening face thereof).

  In this invention, a positioning member is arrange | positioned so that at least one part of a positioning member may protrude from an opening part. Therefore, when the stopper is not positioned to close the opening and no force is applied to the positioning member from the temporary frame side, a part of the positioning member protrudes from the end surface or the pipe end. On the other hand, when a force is applied to the positioning member from the temporary frame side, the positioning member can be accommodated in the accommodation hole. That is, the position of the positioning member can be changed by the elasticity of the biasing member. When the positioning member fluctuates, the urging member exerts a restoring force to return the positioning member to the original position.

  When the stopper closes the opening in a state where the positioning member is pushed into the accommodation hole, the position of the positioning member stays and does not change while being biased to the temporary frame side (stopper) by the biasing member. In this state, a pipe installation member is installed at the end of the pipe, and the pipe is placed between the temporary frames. Since the temporary frame is installed according to the pipe length, the pipe end or main body end face is at a distance substantially in contact with the temporary frame, and the operator puts his hand between the pipe end and the temporary frame to work. There is no space. Even in such a state, the stopper is movable, and when the stopper is retracted from the position where the stopper closes the opening, the positioning member is displaced toward the temporary frame by the restoring force of the biasing member and comes into contact with the temporary frame. While the piping is moved toward the position of the hole provided in the temporary frame, the positioning member comes into pressure contact with the temporary frame while receiving both the force from the temporary frame and the restoring force by the biasing member. When the positioning hole formed in the temporary frame reaches the position of the positioning member of the piping installation member, the positioning member is pushed out to the temporary frame side by the restoring force of the biasing member. The positioning member passes through the hole of the temporary frame and is supported by engaging with the hole of the temporary frame. As a result, the piping is positioned with respect to the temporary frame. Thus, the urging member has elasticity so that the piping can move while the positioning member is in pressure contact with the temporary frame.

  When it comes to the position of the hole in the temporary frame, the positioning member is automatically supported and the pipe is positioned. Therefore, the pipe is reliably installed at a predetermined place without performing a work of installing the pipe to the target position by providing a target or the like.

  The length between the temporary frames conforms to the length of the pipe, and the positioning member protrudes from the pipe end or the main body end face. If it is not accommodated in the accommodation hole, the pipe cannot be arranged between the temporary frames. The positioning member can be maintained in the accommodation hole by closing the opening with the stopper in advance, and the positioning member is moved to the temporary frame by inserting the pipe between the temporary frames and then moving the stopper. It can be made to contact.

  The stopper may be moved when it is desired to move the stopper, or may be moved naturally by some force when the pipe is installed between the temporary frames. When the stopper is appropriately moved by the operator's operation, a position variation operation member that moves the stopper from the outside of the pipe in a state where the pipe is disposed between the temporary frames may be provided. As the position variation operation member, for example, a magnet may be embedded so as to be remotely operated, or it may be directly engaged with a stopper. In the case of direct engagement, the stopper is configured not to substantially protrude from the end or end face of the pipe toward the temporary frame. When piping is placed between temporary frames, there is no space for workers to put their hands on the piping end, so when the end surface is located closer to the temporary frame than the piping end, for example, the direction of movement of the stopper on the end surface It is preferable to use a member in which a groove is formed along the position and the position variation operation member extends along the groove. In this case, a flexible and fibrous member such as a string or a thread may be used.

  In order to prevent the stopper from coming off from the main body during movement, the main body is fixed to the main body at a position near the outer periphery of the main body at a position along the movement direction of the stopper, and is retracted from a position where the opening is closed. It is preferable to provide a stopper locking member for positioning the stopper.

  The body can support the biasing member from the center side of the pipe and can be detachably attached to the body from the center side of the pipe to facilitate the work of accommodating the positioning member in the receiving hole with the stopper closed by the opening. It is preferable to have a supporting member. The support member, the biasing member, and the positioning member are operatively connected. By mounting the urging member and the positioning member and then mounting the lid, it is possible to easily create a state where the positioning member is pushed in by the stopper.

  According to the present invention, piping can be installed easily, accurately, and efficiently without requiring many workers. Moreover, before installing piping between temporary frames, the operation | work which pushes a positioning member in a piping edge part or an end surface can be performed easily.

  Below, with reference to drawings, the member for piping installation which is an embodiment of the present invention is explained.

  FIG. 1 is a cross-sectional view showing a pipe and a plug which is a pipe installation member. FIG. 2 is a plan view of the plug. FIG. 3 is a cross-sectional view of the plug. The plug which is the member for discontinuation publication installation of this embodiment is demonstrated using FIGS. 1-3.

  1 is composed of a vinyl pipe BP and joints 13 and 14, and tubular joints 13 and 14 are attached to the pipe BP at both ends of the pipe 10 with an adhesive or the like. . Plugs 11 and 12 having flanges formed around the outer periphery can be arranged at both ends of the pipe 10, respectively, and the plugs 11 and 12 are in contact with the ends 14 B and 13 B of the joints 14 and 13, respectively. Be placed. The plugs 11 and 12 have a size according to the size of the joints 13 and 14, that is, the diameter of the pipe 10, and are fitted to the end of the pipe 10. The plugs 11 and 12 include main bodies 11K and 12K, bolts 11A and 12A, and springs 11F and 12F, respectively. The main bodies 11K and 12K include lids (support members) 11G and 12G, respectively.

  FIG. 2 shows a plan view (a) of the plug 11 viewed from above and a plan view (b) of the plug 11 viewed from the side. The plug 12 has the same configuration as the plug 11.

  The plug 11 is formed in a columnar shape, and the main body 11K includes a disk-shaped upper part 11S having a diameter covering the area of the opening surface of the pipe end (joint end) and a lower part 11T extending from the upper part 11S. . A lid 11G is detachably attached to the lower portion 11T. The plug 11 is arranged at the pipe end so that the lower part 11T faces the center part PA of the pipe 10 and the upper part 11S having the end face 11U faces the opposite side (temporary frame side) (see FIG. 1).

  FIG. 3 is a sectional view taken along line I-I ′ of FIG. 2, and a housing hole 11 </ b> H is formed around the central axis C in the main body 11 </ b> K of the plug 11. The accommodation hole 11H is constituted by a first space 11M formed in the upper portion 11S and a second space 11N formed in the lower portion 11T, and both are formed in a cylindrical shape. The first space 11M is formed to accommodate most of the bolt 11A, and the opening 11J is formed in the vicinity of the end surface 11U. The size of the diameter of the first space 11M follows the size of the screwing portion 11V in which the male screw of the bolt 11A is formed. The second space 11N accommodates a part of the spring 11F and the bolt 11A, and the diameter of the second space 11N is determined according to the size of the head 11D of the bolt 11A.

  The bolt 11A, the spring 11F, and the lid 11G are independently configured and are operatively connected to each other from the center of the pipe toward the temporary frame. When the bolt 11A and the spring 11F are sequentially inserted from the lower part 11T with the lid 11G removed, and then the lid 11G is tightened, the first end 11P of the spring 11F comes into contact with the bottom surface 11E of the second space 11N, The two end portions 11Q are in contact with the head 11D of the bolt 11A.

  The lid 11G is mounted while being screwed to the lower portion 11T, and supports the first end portion 11P of the spring 11F. The spring 11F is a compression coil spring having a predetermined elasticity, and urges the bolt 11A toward the end surface 11U of the main body 11K. The bolt 11A connected to the second end portion 11Q of the spring 11F extends along the accommodation hole 11A, and the head 11D of the bolt 11A contacts the end surface 11C of the second space 11N of the accommodation hole 11H.

  When no external force is applied to the bolt 11A toward the center of the pipe, that is, when the bolt 11A is not pushed in from the temporary frame side, the threaded portion 11V of the bolt 11A exceeds the opening 11J of the receiving hole 11H and the main body 11K. It protrudes from the end surface 11U (see FIG. 3A). In other words, the space size of the accommodation hole 11H of the main body 11K and the length and size of the spring 11F and the bolt 11A are determined so that the tip of the bolt 11A protrudes from the end surface 11U.

  As shown in FIG. 2A, the end surface 11U of the plug 11 constitutes a part of the end surface 11U and can slide along a direction SD (hereinafter referred to as a moving direction) SD passing through the central axis of the plug 11. A rod-like stopper 11L is arranged. The cross-sectional shape of the stopper 11L is a trapezoid, and the upper surface UL forms a part of the end surface 11U. On the other hand, the lower surface US of the stopper 11L is in contact with a moving surface TU that is parallel to the end surface 11U and formed along the moving direction SD of the stopper 11L. The stopper 11L is formed with a hole HL penetrating from the upper surface UL to the lower surface US, and the thread 22 is passed through the hole HL and tied (see FIGS. 2A and 3C). (Note that the yarn 22 is not shown in FIGS. 1, 2B, 3A, and 3B).

  A locking member 11W that locks the stopper 11L is fixed to the moving surface TU in the vicinity of the outer periphery of the end surface 11U and in the movement direction SD of the stopper 11L. The cross-sectional shape of the locking member 11W is a trapezoid, and a groove GR is formed along the movement direction SD on the surface constituting a part of the end surface 11U. The shape of the groove GR is determined so that the position of the yarn 22 is equal to or less than the end face 11U when the yarn 22 is extended along the movement direction SD.

  Since the cross-sectional shape of the stopper 11L is trapezoidal, the stopper 11L does not vary along the central axis direction C of the plug 11 and moves only along the end surface 11U. That is, the stopper 11L does not come off from the end surface 11U. And the stopper 11L slides along the space KT formed according to the cross-sectional shape of the stopper 11L, and is movable within the distance interval MD from the opening 11J to the locking member 11W. When the bolt 11A is accommodated in the accommodation hole 11H and the stopper 11L moves to a position where it closes the opening 11J, the bolt 11A is maintained in a state of being pushed into the accommodation hole 11H. In the process of manufacturing the plug 11, since the thread 22 is passed through the hole HL and the stopper 11L is fitted into the space KT, a slight gap is formed between the end of the stopper 11L near the hole HL and the moving surface TU. (See FIG. 3C).

  FIG. 4 is a diagram illustrating a process of installing a pipe. The piping installation method will be described with reference to FIG. However, FIG. 4 does not show the thread attached to the plugs 11 and 12.

Before placing concrete, first, the stopper 11L is moved to a position where the opening 11J is closed with the cover 11G of the plug 11 removed and the spring 11F and the bolt 11A removed. Then, the bolt 11A and the spring 11F are inserted into the plug 11 and the lid 11G is tightened. Thereby, as shown in FIG. 3B, the spring 11F exerts a restoring force so as to push back the bolt 11A toward the stopper 11L while the bolt 11A is housed in the housing hole 11H. Such plugs 11 and 12 are respectively arranged at the ends of the pipe 10.

  Plate-like temporary frames (form frames) 20 and 21 are installed in advance according to the pipe length, and holes 20R and 21R for pipe positioning are formed, respectively. The pipe 10 is inserted between the pair of temporary frames 20 and 21. At this time, the thread of the plugs 11 and 12 is extended along the groove formed in the locking member of each plug so that the operator can hold the thread from the outside of the pipe 10.

  When the pipe 10 is inserted between the temporary frames, the end surfaces 11U and 12U of the plugs 11 and 12 are in contact with the inner surfaces of the temporary frames 20 and 21, respectively. In this state, the operator pulls the thread attached to the plugs 11 and 12 along the movement direction of the stopper, and retracts the position of the stopper 11L from the position where the opening 11J closes. Thereby, the bolts 11A and 12A are pushed out to the temporary frame side by the restoring force of the springs 11F and 12F, and the front ends of the bolts 11A and 12A come into contact with the temporary frames 20 and 21, respectively (see FIG. 4A).

  The temporary frames 20 and 21 have holes 20R and 21R formed coaxially at predetermined positions, and the holes 20R and 21R have such a diameter that the threaded portions 11V and 12V of the positioning bolts 11A and 12A pass through. Have. The operator moves the water distribution pipe 10 so that the axis E (see FIG. 1) of the water distribution pipe 10 coincides with the axes of the plate holes 20R and 21R. During this time, the springs 11F and 12F bias the bolts 11A and 12A, and the bolts 11A and 12A are in pressure contact with the temporary frames 20 and 21.

  When the screwing portions 11V and 12V of the bolts 11A and 12A come to the positions of the holes 20R and 21R, the bolts 11A and 12A are pushed out toward the temporary frames 20 and 21 by the restoring force of the springs 11F and 12F. 12A protrudes from the temporary frames 20 and 21 (see FIG. 4B). The bolts 11A and 12A are supported by engaging with the holes 20R and 21R, whereby the pipe 10 is positioned. Nuts (not shown) are fitted to the bolts 11A and 12A via washers (not shown), and the pipe 10 is fixed more firmly by tightening the nuts.

  After the pipe 10 is fixed between the temporary frames 20 and 21, a predetermined amount of cement is poured while being tamped. When the cement solidifies into concrete, the nut is loosened and the nut is removed along with the washer. Then, by removing the temporary frames 20 and 21 and removing the plugs 11 and 12 in a state where the concrete wall surface appears, the pipe 10 is installed in the concrete wall (see FIG. 4C).

  As described above, according to the present embodiment, the plugs 11 and 12 installed at the end of the pipe are configured as pipe installation members, the accommodation hole 11H is formed in the plug 11, and the spring 11F and the bolt 11A are provided. Operatively connected. In addition, a stopper 11L that can move along the end surface 11U of the plug 11 is provided. The opening 11J of the accommodation hole 11H of the stopper 11L can be closed in a state where the bolt 11A is pushed into the accommodation hole 11H. When the stopper 11L is moved, the bolt 11A is pushed out to the temporary frame side by the elastic force of the spring 11F.

  The pipe may be constituted by a paper pipe, and can be applied to a gas pipe other than a water pipe, a ventilation pipe, and the like. Moreover, the frame material installed as it is after a concrete placement as a penetration frame material may be sufficient, and the frame material for construction for installing formal piping may be sufficient. The bolts 11 </ b> A and 12 </ b> A may be bolts other than the T type, and may be configured such that the accommodation hole and the bolt do not contact each other. A rigid member for positioning may be attached to the spring instead of the bolt. Further, the bolt 11A, the spring 11F, and the lid 11G may be integrated. Instead of connecting the lid 11G, the spring 11F, and the bolt 11A in order, the spring may be wound around the bolt. The locking member 11W may be fixed to the moving surface TS with a tape or an adhesive, but is fixed by attaching a pin to the bottom surface of the locking member 11W by providing a hole in the moving surface TS and fitting the pin. Also good.

  You may comprise so that a plug may be inserted in piping, without using a joint. For example, a male screw may be formed on the outer peripheral surface of the plug, and the fitting may be screwed into a joint in which a female screw is formed, or may be attached to the pipe. In the present embodiment, the end surfaces 11U and 12U are located on the outermost side (temporary frame side) along the longitudinal direction of the pipe, but the plug is brought into the pipe so that the end face of the plug is not more than the opening face of the pipe end. You may make it the structure accommodated. Further, the end face may be formed in a ring shape only in the vicinity of the circumferential surface and the opening, and the other part may be concave, instead of being on the same plane as in the present embodiment.

  Rubber may be applied as an elastic member instead of the spring. For example, when the rubber is attached to the center side of the pipe of the main body and the head of the bolt is brought into contact with one surface of the rubber, the bolt is retracted to the center side of the pipe due to rubber elasticity. The bolt is biased toward the temporary frame by the elasticity of the rubber. Furthermore, elastic members other than springs and rubber may be used. Or, it can be deformed, biased, or fluctuated by force, such as a resilient container filled with air, such as a resilient balloon infused with air, or a resilient bellows mechanism. A member that urges a positioning member such as the above may be applied.

  The stopper 11L slides along the end surface 11U. However, the stopper 11L may be configured to change the position inside the pipe instead of sliding, and may be moved so as not to exceed the end face 11U or the pipe end. Moreover, the shape of the stopper 11L is arbitrary and may be formed so as to close the opening 11J. Furthermore, the stopper locking member 11W may not be provided.

  In order to move the stopper 11L, the operator may be able to operate it with a member other than the thread 22. For example, the stopper 11L may be moved by remote operation using a magnet or the like. Furthermore, you may comprise so that a stopper may be moved by predetermined force, when piping is installed between temporary frames.
