Description

Building element's mold processing and building element built-in fitting's fixed stopper

Technical Field

The utility model relates to the technical field of building tools, in particular to a processing die of a building component and a fixing plug of an embedded part of the building component.

Background

In the production process of building components, some building components need to be provided with preformed holes, and other building components need to be provided with embedded parts in the building in advance. It is common to use some hole forming die for building elements requiring preformed holes. However, for building elements requiring embedments, it is necessary to install them using a dedicated installation device for the building embedments. The embedded part and the preformed hole are completely different processes in construction of the building component, and the preformed hole is a hole reserved in other professional construction in advance in concrete pouring, so that the trouble of hole punching and damage to the building component, such as preformed holes of water, electricity and warm wires, in other professional construction are avoided. The embedded part is required to be integrally cast with the building component, and the embedded part is generally made of a metal component and is used for being connected with other building components or external engineering equipment for installation and fixation.

For building elements, a preformed hole is required, and in the related art, chinese patent literature: CN112976255a, which provides a pore forming module, comprising: a skeleton, a connecting part and a flexible layer. The pore-forming module is fixed on a processing mould of the building component by utilizing the framework, the framework is used for forming pores, and the flexible layer wraps the framework by means of glue injection and the like. After the flexible layer has allowed the building element to fully set, the building element is easily separated from the pore-forming module.

However, this solution only allows for the provision of preformed holes in the building elements, which cannot be used for the mounting of the building elements to each other, and cannot allow for the formation of a firm building system between the building elements. In order to form a firm building system between the production and processing prefabricated building components, the embedded components are required to be installed in the building components by means of the installation device of the embedded components, and the embedded components are required to be subjected to various problems such as impact of concrete pouring on the embedded components and pollution prevention of the embedded component structure in the installation process, so that the technical problem of the preformed holes does not provide any technical teaching for installation of the embedded components.

When the embedded part required in the building component is a threaded sleeve, the requirements of assembly, formwork supporting and fixing during component installation are met. In the related art, the building component threaded sleeve is pre-embedded in the following processing modes:

mode one: (1) Measuring the position of the reserved thread sleeve on the die table of the building component, and marking; (2) Cutting out round steel with proper size, and performing welding operation on the marked position, wherein the round steel is used as an anchoring and positioning device of the sleeve; (3) The thread sleeve with the steel plate at the bottom is stuck with double-sided sponge strips along the periphery to prevent cement paste from entering the sleeve; (4) then threading the steel inside the threaded sleeve; (5) And finally, installing a tool piece above the corresponding threaded sleeve, wherein the tool piece is used for pressing the threaded sleeve to prevent the threaded sleeve from moving.

Mode two: (1) Measuring the position of the reserved thread sleeve on the die table, and marking; (2) A base with a magnet is used and fixed at the marked central position; screwing the threaded sleeve into a screw rod with a magnet as the center; (3) After the member is manufactured and maintained, hoisting the member, and screwing out a screw rod anchored in the threaded sleeve by using a tool; (4) Chiseling a base embedded in concrete using a hammer and chisel; and (5) cleaning sundries in the sleeve, and checking the quality of the sleeve. Two ways of the first way and the second way generate two technical problems:

in the related art, chinese patent literature: CN215511614U provides a pre-buried stop device of prefabricated component sleeve, including the magnet that is used for adsorbing the steel mould, the constraint is installed the bolt on the magnet, the screw rod of bolt runs through the magnet, there is radial locating plate on the upper surface of magnet through first nut fixed mounting, radial locating plate's diameter and telescopic internal diameter looks adaptation, telescopic lower terminal surface offsets with the steel mould and leans on, the telescopic up end is worn out to the screw rod of bolt, telescopic up end has axial locating plate through second nut fixed mounting, the sectional area of axial locating plate is greater than telescopic sectional area, first nut and second nut are all connected with the screw rod of bolt. However, the technical proposal does not give any technical teaching for solving the direct separation of the building component and the fixing device of the reserved sleeve and simplifying the subsequent processing technology of the building component.

In one aspect, the method includes the steps of pouring a building element. The reserved thread sleeve is needed to be accurately positioned at the reserved position of the thread sleeve in the building member, and is firmly fixed, but when concrete is poured and vibrated, the reserved sleeve is displaced and inclined, cement paste easily pollutes the thread of the reserved thread sleeve, and an independent sealing device is needed to be arranged.

On the other hand, after the building components are processed and maintained. Screw thread sleeve fixing device can't directly separate with screw thread sleeve, needs to reserve screw thread sleeve and sleeve fixing device split, leads to the construction process more, demolishs the in-process of reserving telescopic fixing device, still can produce the influence to building element's reservation sleeve or concrete structure, and improper operation very easily leads to the quality problem of product and all needs to repeat above-mentioned process for every building element processing of accomplishing.

The idea of the present utility model is to improve the fixing device of the reserved sleeve 140 of the building element 300, wherein the fixing device is the fixing plug 100 of the embedded part of the building element according to the present utility model ("the fixing plug of the embedded part of the building element" hereinafter referred to as "fixing plug"). The reserved sleeve 140 is stably sleeved on the fixed plug 100 in the processing process of the building member 300, after the building member 300 is processed, the fixed plug 100 is not required to be additionally detached, the separation of the building member 300 and the fixed plug 100 can be realized by hoisting the building member 300, meanwhile, the subsequent processing of the same building member 300 is also not required to be repeated again for the installation of the fixed plug 100, and the processing procedure of the building member 300 is optimized.

The utility model will be described in detail below with reference to the accompanying drawings 1-7 in conjunction with examples.

Referring to fig. 1-2, a first aspect of the present utility model discloses a fixing plug 100 comprising: a connector 110, a rigid skeleton 120, and a flexible layer 130. The connection member 110 is connected to the hard frame 120 and fixes the fixing plug 100 to a corresponding position of a working mold 200 of a building member ("working mold of a building member" hereinafter referred to as "working mold"), and the flexible layer 130 covers the entire outer surface of the hard frame 120.

Wherein, in connection with fig. 3, the hard skeleton 120 comprises: the three parts of the insertion part 121, the transition part 122 and the base 123, the insertion part 121 is used for being inserted into a reserved sleeve 140 of a building component ("reserved sleeve of the building component" hereinafter referred to as "reserved sleeve"), and the outer diameter of the insertion part 121 is smaller than the inner diameter of the reserved sleeve 140, so that separation and connection between the insertion part 121 and the reserved sleeve 140 can be realized in a plug-in mode.

The outer diameter of the insertion part 121 provided with the flexible layer 130 is slightly larger than that of the reserved sleeve 140 through the flexible layer 130 covering the surface of the insertion part 121, so that the insertion part 121 and the reserved sleeve 140 are tightly connected. During the processing of the building member 300, the insertion portion 121 covered with the flexible layer 130 enables the reserved sleeve 140 to be stably sleeved on the insertion portion 121, and after the maintenance of the building member 300 is completed, the building member 300 and the fixed plug 100 can be directly separated from each other by lifting the building member 300 due to the corresponding elasticity of the flexible layer 130, without additional disassembly of the fixed plug 100, thereby improving the construction efficiency. The fixing plug 100 is fixed on the processing mould, and also does not need additional disassembly, and is directly sleeved into a new reserved sleeve 140, and the reserved sleeve 140 can be a screw steel sleeve generally, so that the processing of the building component 300 of a new round can be started.

The outer diameter of the base 123 of the hard skeleton 120 is larger than the inner diameter of the reserved sleeve 140, so that after the insertion part 121 completely enters the reserved sleeve 140, the upper surface of the base 123 is contacted with the lower surface of the reserved sleeve 140, meanwhile, the flexible layer 130 arranged on the outer surface of the base 123 is contacted with the lower surface of the reserved sleeve 140, thereby sealing the lower side of the reserved sleeve 140 and avoiding the pollution to the inner structure of the reserved sleeve 140 caused by the fact that substances such as concrete slurry enter the reserved sleeve 140 from the lower end of the reserved sleeve 140 in the processing process of the building member 300.

Specifically, referring to fig. 5 or 6, the base 123 is a truncated cone or a truncated pyramid structure. In the process of manufacturing the building element 300, the lower surface of the base 123 is disposed on a manufacturing mold, and substances such as concrete are filled in the manufacturing mold, and after the whole building element 300 is manufactured and maintained, the building element 300 is separated from the manufacturing mold 200, and the reserved sleeve 140 is also separated from the fixing plug 100, at this time, a regular round table or a prismatic table shaped opening is formed at the position where the reserved sleeve 140 is disposed on the building element 300. Further, the outer surface of the base 123 is also provided with the flexible layer 130, and the flexible layer 130 is made of a substance such as silica gel or rubber, so that the flexible layer 130 does not react with the substance such as concrete of the building element 300, is insoluble in water or other solvents during the processing of the building element 300, and has relatively stable chemical properties. The flexible layer 130 ensures that the fixing plug 100 can be used multiple times, and also allows the surface of the opening of the truncated cone or pyramid formed when the building element 300 is separated from the process to be relatively smooth, thereby improving the overall quality of the building element 300.

The insertion portion 121 is disposed at the middle position of the base 123, so that the lower end of the retaining sleeve 140 is disposed at the middle position of the opening of the building element 300, which makes the overall quality of the whole building element 300 high, and is convenient for aligning or connecting other building elements during the subsequent operation of the building element 300. The shape of the insertion portion 121 may be a cylinder or a prism, and the specific shape may be selected according to the shape of the inner wall of the preformed sleeve 140.

The insertion portion 121 further comprises a leading end 121a, the leading end 121a serving to facilitate the insertion portion 121 into the interior of the preformed sleeve 140. The lower surface of the insertion portion 121 partially coincides with the upper surface of the base 123, and the upper surface of the insertion portion 121 goes deep into the interior of the preformed sleeve 140, so that the area of the upper surface of the insertion portion 121 is smaller than the area of the lower surface of the insertion portion 121, for example, the guiding end 121a of the insertion portion 121 may have a truncated cone, a truncated pyramid, a cone, a pyramid or the like.

More specifically, the rigid skeleton 120 further includes a transition portion 122, and the transition portion 122 is located between the insertion portion 121 and the base 123, serving as a transition between the insertion portion 121 and the transition portion 122. The upper surface of the transition portion 122 is equal in area to the lower surface of the insertion portion 121, and the lower surface of the transition portion 122 is smaller than the upper surface of the base 123 and larger than the upper surface of the transition portion 122. The junction between the side surface of the transition part 122 and the connection part between the insertion part 121 and the contact part is chamfered, so that the problem of stress concentration is avoided.

More specifically, the outer structure of the fixing plug 100 is constructed by the flexible layer 130 and the hard frame 120 together, and in general, the flexible layer 130 covers the outer surface of the hard frame 120, and the shape of the fixing plug 100 is determined by the hard frame 120. However, after the building member 300 is processed and maintained, the flexible layer 130 made of rubber or other material is separated from the fixed plug 100 under the action of external force, but the flexible layer 130 of the fixed plug 100 is attached to the reserved sleeve 140 to generate adsorption force, and the adsorption force makes the building member 300 separate from the fixed plug 100 to generate certain resistance, so that the flexible layer 130 covered on the insertion part 121 is provided with a plurality of grooves 131, and the grooves 131 make a part of space reserved between the flexible layer 130 and the reserved sleeve 140, so that the separation force between the reserved sleeve 140 and the fixed plug is reduced when the reserved sleeve 140 is separated from the fixed plug.

In the process of processing the building component 300, the reserved sleeve 140 is generally a deformed steel reserved sleeve 140, the deformed steel reserved sleeve 140 is beneficial to the subsequent building operation, a traditional fixing device similar to the fixed plug 100 is connected with the reserved sleeve 140, and a screw rod matched with the screw teeth on the inner wall of the deformed steel reserved sleeve 140 is generally adopted, but the screw rod is fixed in a mode of screw rod, on one hand, after the building component 300 is processed and maintained, the screw rods need to be screwed out one by one, and the process is very troublesome; on the other hand, the building member 300 will vibrate and impact the preformed sleeve 140 during the forming process, the screw rod fixing manner is easy to damage the screw teeth in the preformed sleeve 140, and in order to prevent substances such as concrete from entering the preformed sleeve 140 to pollute the screw teeth in the preformed sleeve 140, a separate sealing device is also required.

By arranging the flexible layer 130, on one hand, the damage to the thread in the reserved sleeve 140 caused by the impact of the vibration and other processes on the reserved sleeve 140 in the processing process of the building member 300 is solved; on the other hand, the flexible layer 130 covering the outer surface of the hard skeleton 120 has a sealing effect, so that the problem of protecting the thread inside the preformed sleeve 140 is solved.

More specifically, the hard frame 120 of the present utility model is made of plastic, nylon, or metal. The hard skeleton 120 has a skeleton cavity 124 formed therein, and the connecting member 110 has a part connected to the skeleton cavity 124 and another part connected to the processing mold.

The hard skeleton 120 and the connecting piece 110 may be integrally formed or detachable. When the connecting piece 110 is detachably connected with the hard skeleton 120, the inner wall of the skeleton cavity 124 is provided with screw teeth, the connecting piece 110 adopts a screw rod matched with the screw teeth, one part of the screw rod is screwed into the skeleton cavity 124, and the other part of the screw rod can be welded on a processing die or provided with the screw teeth matched with the connecting piece 110 on the processing die, so that the other part of the connecting piece 110 is screwed into the screw teeth of the processing platform part, thereby fixing the fixing plug 100 on the processing die 200.

The connecting member 110 adopts a screw rod, which not only fixes the fixing plug 100 to the processing mold 200, but also supports the entire fixing plug 100, and particularly, the hard skeleton 120 is made of plastic or other materials for reducing the cost. In order to further enhance the supporting effect of the screw rod on the hard frame 120, the cavity of the base 123 and the first cavity 124a are both circular, the diameter of the second cavity 124b is larger than that of the first cavity 124a, the screw rods adopted by the corresponding connecting piece 110 are integrally formed, the screw rod positioned in the first cavity 124b is the first screw rod 111, the screw rod positioned in the second cavity 124b is the second screw rod 112, the diameter of the second screw rod 112 is larger than that of the first screw rod 111, for example, the diameter of the second cavity 124b is twice that of the first cavity 124a, and the diameter of the corresponding second screw rod 112 is twice that of the first screw rod 111.

More specifically, the aspect ratio of the various portions of the fixation plug 100, particularly the hard frame 120 portion, is particularly important in order to improve the overall stability and durability of the fixation plug 100. The insert 121 of the rigid frame 120 has a height H1, the transition 122 has a height H2, and the base 123 has a height H3, the ratio of H1 to H2 to H3 being in the range: (5-7): (1-3): (2-4); the maximum width of the insertion portion 121 of the rigid skeleton 120 is D1, the maximum width of the transition portion 122 is D2, and the maximum width of the base 123 is D3, D1: d2: the ratio range of D3 is: (0.5-1.5): (2-3): (4-5); the radial width of the first cavity 124a is R1, and the radial width of the second cavity 124b is R2, R1: the ratio of R2 is: 1:2.
