Description
Technical Field
The invention relates to the field of building template systems, in particular to a sleeve for a wall penetrating screw and a wall penetrating assembly using the sleeve.
Background
Building form systems are often used in building construction. The building template system generally comprises templates, a wall penetrating assembly, a back edge, a fastening nut and the like, the wall penetrating assembly comprises a wall penetrating screw and a sleeve, two templates are used for the description of the two templates, the two templates are respectively marked as a first template and a second template, the first template and the second template are oppositely arranged, the first template is provided with a first through hole, the second template is provided with a second through hole, the back edge is respectively arranged on the outer sides of the first template and the second template, the sleeve is arranged between the first template and the second template, the wall penetrating screw sequentially penetrates through the first through hole, the sleeve and the second through hole, the nut is welded at one end of the wall penetrating screw, and the other end of the wall penetrating screw is locked on the corresponding back edge through the fastening nut. Pouring cement between the first template and the second template, and removing the first template and the second template after the cement is solidified, so as to obtain a wall body, for example, as disclosed in China patent application No. CN201821271233.5 (bulletin No. CN 208686087U) for building template assembly. In this process, the sleeve has two functions: firstly, a wall body with fixed thickness is obtained by enabling a first template and a second template to be separated by a certain distance; and secondly, the wall penetrating screw in the protective sleeve is prevented from being adhered to cement, so that after the cement is solidified, the wall penetrating screw can be conveniently taken down and can be reused.
The use process of the building template system is generally as follows: firstly, a first template is erected, a wall penetrating screw rod is put into a first through hole from the outer side of the first template, and a sleeve pipe is sleeved on the wall penetrating screw rod from the inner side of the first template; then, a second template is erected again, and the sleeve is sleeved on the wall penetrating screw and is positioned between the first template and the second template; when the second template is erected, the constructor also needs to pass through the wall penetrating screw rod through the second through hole of the second template and extend out of the second template; finally, the other end of the wall penetrating screw rod is locked on the corresponding back ridge through a fastening nut; pouring cement between the first template and the second template, and taking down the wall penetrating screw for recycling after the cement is solidified.
In the above use process, the building template system has the following problems: firstly, the sleeve can easily slide off the wall-penetrating screw; specifically, when the wall penetrating screw is not penetrated through the second template, namely, one end of the wall penetrating screw, which is positioned between the first template and the second template, is suspended, the wall penetrating screw sometimes sags due to dead weight, and at the moment, the sleeve is inclined downwards and easily slides off the wall penetrating screw, particularly, when the second template is erected, the sleeve which slides between the first template and the second template is not easy to pick up, and the sleeve can be picked up after the second template is sometimes removed, so that the trouble is caused; secondly, when a new sleeve is needed to be added, the sleeve installation efficiency is low; specifically, before the first and second templates are both installed in place and intended to be poured into cement, if a missing sleeve is found, or if a wall penetrating screw is required to be set again in consideration of strength and safety (at this time, a new through hole is required to be set in the first template or the second template, and a new sleeve and a new wall penetrating screw are put in), the second template that has been installed needs to be disassembled and separated from the first template by a certain distance to leave a space for operating the sleeve; the using process of the building template system is repeated, namely, a wall penetrating screw rod is put into a first through hole of a first template from the outer side of the first template, a sleeve pipe is sleeved on the wall penetrating screw rod from the inner side of the first template, a second template is mounted at a proper position again, and the wall penetrating screw rod passes through a second through hole of the second template; after the first template and the second template are installed in place, if a new sleeve is needed to be additionally arranged, the second template needs to be installed and detached for multiple times, the sleeve installation efficiency is low, and the construction cost is high; thirdly, the sleeve cannot be reused; specifically, after the cement is solidified into the wall body, the sleeve and the wall body are in a negative pressure state, so that the sleeve is not easy to detach from the wall body, and the sleeve cannot be reused.
Solutions have been designed to address the first technical problem (the sleeve may easily slip off the wall-penetrating screw) and the second technical problem (the sleeve installation efficiency is low when a new sleeve is added). For example, chinese patent application No. CN201720252637.9 (bulletin No. CN 206625571U) entitled "form counter-pulling structure with plug", the form counter-pulling structure is used for being tied between two opposite forms, the form is provided with a form hole, the form counter-pulling structure comprises a counter-pulling screw and an elastic plug mounted on the counter-pulling screw; the elastic plug comprises a connecting sleeve sleeved on the opposite-pulling screw rod and an elastic sleeve sleeved on the connecting sleeve and used for plugging between the template hole and the opposite-pulling screw rod after the opposite-pulling screw rod penetrates through the template hole. When the second plugging sleeve is installed from the outer side of the second template, the wall penetrating screw (i.e. the opposite-pulling screw in the patent) extends out of the second template, namely when the second plugging sleeve is installed, one end of the wall penetrating screw passes through the second through hole of the second template and is not suspended between the first template and the second template, so that the sleeve (i.e. the screw sleeve in the patent) cannot slide from the wall penetrating screw; in addition, when a new sleeve is needed to be additionally arranged, because the outer wall size of the screw sleeve is smaller than the aperture of the template, the elastic sleeve of the elastic plug has elasticity, so that the sleeve (i.e. the screw sleeve in the patent) can be sleeved outside the wall penetrating screw (i.e. the opposite-pulling screw in the patent) without disassembling the second template, and the sleeve installation efficiency is higher. The above patent does not give a sleeve reuse scheme.
The following patent devised a solution to the third technical problem described above (the casing being unable to be reused). For example, chinese patent application CN200920206497.7 (publication No. CN 201531116U) discloses a recyclable wall-penetrating pipe, in which an inflatable hollow elastic pipe body is provided, the pipe body is embedded in concrete as a pipe in an inflated state, and the pipe body is easily taken out from the concrete for recycling due to its reduced external dimension in a deflated state. For another example, chinese application No. CN200910191068.1 (bulletin No. CN101691811 a) applies for a recyclable wall-penetrating catheter, detachable arc blocks are connected by a detachable hinge device, two ends of the catheter can be sealed by a sealing adhesive tape, or cotton yarn is plugged into the catheter, after concrete is solidified, the sealing adhesive is broken or the cotton yarn is taken out, and a connecting pin of the detachable hinge device is pulled out, so that each detachable arc block is separated and taken out for recycling. The sleeves in the two patents can be conveniently detached and reused, but the problems that the sleeves are easy to slide from the wall-penetrating screw and the sleeve installation efficiency is low when a new sleeve is additionally arranged are not solved in the two patents.
In combination, the sleeve for the wall penetrating screw and the wall penetrating assembly using the sleeve can be further optimized.
