Description

Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, and in particular to an energy-saving prefabricated building wall. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] In existing prefabricated houses, the connection between the walls is fixed by screws to each plate, and there must be no deviation in the position, otherwise the wall will be distorted. If the screws are removed and re-fixed, it will cause screw holes on the wall and cause certain damage to the surface of the plate. Summary of the invention

[0004] The purpose of the present invention is to provide an energy-saving assembled building wall to solve the problem that the existing assembled walls in the above-mentioned background technology have poor fixing effect and damage to the wall due to the use of screws.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] An energy-saving assembled building wall comprises a first wall and a second wall, wherein the first wall is provided with an insert block, the second wall is provided with a slot for inserting the insert block, the second wall is provided with a first cavity, the first cavity is slidably connected with a piston 1 and a piston 2, the piston 1 and the piston 2 are respectively fixed with a piston rod 1 and a piston rod 2, the end of the piston rod 1 away from the piston 1 is located in the slot and is used to contact the insert block, the piston 1 and the piston 2 are respectively connected with a spring 1 and a spring 2 between the piston 1 and the inner wall of the first cavity, the insert block is provided with a limiting hole for inserting the piston rod 2, and the second wall is provided with an air hole connected with the first cavity and a closing member for closing the open and closed air hole.

[0007] The principle of the present invention is as follows: during assembly, the second wall is fixed, the first wall is pushed, and the plug block is aligned with the slot during the pushing process to ensure that the first wall is aligned with the second wall. The plug block is inserted into the slot, contacts with the piston rod 1 and pushes the piston rod 1, the piston rod 1 will drive the piston 1 to slide in the first cavity, the air pressure in the first cavity will change during the sliding process of the piston 1, the piston 2 will be affected by the air pressure, when the plug block slides to the limit hole and the piston rod 2 are aligned, the piston 2 will push the piston rod 2 to insert into the limit hole, so as to fix the first wall and the second wall, and the spring 1 and the spring 2 will both undergo elastic deformation during the process. During dismantling, the first cavity is connected to the outside through the air hole by opening the closure, the air pressure in the first cavity is restored, and the air pressure effect is lost, the piston 2 will slide in the opposite direction under the action of the spring 2, and drive the piston rod 2 to slide in the opposite direction until it is separated from the limit hole, and the limit fixing effect disappears, at this time, it is only necessary to pull out the second wall, and in the process, there is also a spring 1 to push the piston 1, and the piston 1 will drive the piston rod 1 to assist in pushing away the second wall.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. The first wall and the second wall can be well aligned during assembly by the corresponding plug-in blocks and the plug-in blocks inserted into the slots can achieve a certain limiting effect to prevent the wall from being twisted and affecting the overall stability of the house. In addition, different numbers of plug-ins and slots can be set according to the actual sizes of the first wall and the second wall to achieve the best splicing and fixing effect.

[0010] 2. In the process of pushing the first wall, the plug block is used to push the piston rod one, and the air has a certain compressibility. The air pressure in the first cavity changes to make the piston rod two insert into the limit hole, so as to achieve the effect of fixing the wall. Compared with the existing fixation by screws, the present invention can not only achieve a good effect of fixing the wall, but also will not damage the wall, and is reversible, that is, the walls can be disassembled, which can be convenient for later maintenance or replacement; in addition, the entire process only requires external force to push the first wall, and no other operations can be performed to fix the first wall and the second wall through a series of linkages, which simplifies the assembly process, reduces labor, and effectively improves work efficiency.

[0011] Furthermore, the first cavity is arranged to surround the slot, and each slot corresponds to two piston rods 2, the two piston rods 2 are arranged symmetrically, and the limiting hole is arranged vertically. By surrounding the slot with the first cavity, the insert block can contact and push the piston rod 1, and the air pressure in the first cavity can be changed by the sliding of the piston rod 1. The two pistons 2 will be affected by the air pressure. When the insert block slides to align the limiting hole with the piston rod 2, the two pistons 2 will push the piston rod 2 to be inserted into the limiting hole at the same time. The insert block is fixed by multiple limiting, thereby improving the stability of the wall after splicing.

[0012] Furthermore, the second piston rod includes a fixed rod and a movable rod, both of which are hollow rods, and are fixedly connected by a spring, a first airbag and a second airbag are arranged in the fixed rod, glue A is arranged in the first airbag, glue B is arranged in the second airbag, and a needle for piercing the first airbag and the second airbag is arranged in the movable rod. In general, assembled walls need to be easily disassembled, but if there are severe environments such as strong winds and earthquakes in the local area, and the strength of the wall needs to be strengthened, then disassembly is not the first requirement. At this time, the vibration caused by strong winds or earthquakes will drive the movable rod to move back and forth, and then pierce the first airbag and the second airbag, so that glue A and glue B are mixed, filling the gaps in the wall, sticking the wall together, and strengthening the strength of the wall.

[0013] Furthermore, a liquid outlet hole is provided on the side wall of the movable rod, and a part of the mixed glue A and glue B can flow out from the liquid outlet hole, so that the glue has a wider range of action and a better stabilizing effect.

[0014] Furthermore, the end of the plug block is wedge-shaped, and the end of the piston rod one is wedge-shaped to match the plug block. A second cavity connected to the limit hole is provided in the plug block, and a piston three is slidably connected in the second cavity. A spring three is connected between the piston three and the plug block, and a piston rod three is fixedly connected to the piston three. The slot is also provided with a socket for inserting the piston rod three.

[0015] When the insert block is inserted into the slot, the wedge-shaped end of the insert block abuts against the wedge-shaped end of the piston rod one and pushes the piston rod one to slide. The piston rod one drives the piston one to slide. Since the piston rod two has not yet aligned with the limiting hole, the air pressure in the first cavity will increase when the piston one slides. When the piston rod two is aligned with the limiting hole, the piston rod two will slide quickly into the limiting hole with the piston two under the action of the air pressure in the first cavity, thereby fixing the first wall and the second wall. In the process of the piston rod two being inserted into the limiting hole, the gas in the limiting hole is pushed into the second cavity. The air pressure in the second cavity will push the piston rod three to be inserted into the insertion hole through the piston three, thereby achieving the effect of secondary fixing of the first wall and the second wall. Through the process of the insert block being inserted into the slot, the piston rod two is inserted into the limiting hole and the piston rod three is inserted into the insertion hole, thereby achieving the double fixation of the first wall and the second wall, thereby effectively improving the stability of the wall.

[0016] Furthermore, each slot corresponds to two first cavities, which are symmetrically arranged on both sides of the slot, and there are two limiting holes, which are symmetrically arranged on both sides of the second cavity. The plug block is fixed by multi-directional and multi-position limiting, thereby improving the stability of the wall after splicing.

[0017] Furthermore, the piston rod 3 is provided with a through hole 3, and the second wall is provided with a through hole 4 connected to the insertion hole. When the piston rod 3 is inserted into the insertion hole, the through hole 3 is connected with the through hole 4. By setting the through hole 3 and the through hole 4, it can be judged whether the piston rod 3 is effectively inserted into the insertion hole by whether the two are aligned, so as to achieve an effective fixing effect.

[0027] The following is further described in detail through specific implementation methods:

[0028] The figure marks in the drawings of the specification include: first wall 1, second wall 2, plug block 3, slot 4, first cavity 5, piston one 6, piston two 7, piston rod one 8, piston rod two 9, fixed rod 91, movable rod 92, A glue 93, B glue 94, elastic member 95, needle 96, spring one 10, spring two 11, limiting hole 12, liquid outlet hole 13, second cavity 15, piston three 16, spring three 17, piston rod three 18, through hole three 19, through hole four 20, and plug hole 21.

[0029] Embodiment 1 is basically as shown in the attached Figures 1 to 4 As shown:

[0030] An energy-saving assembled building wall comprises a first wall 1 and a second wall 2, wherein an insert block 3 is integrally formed on the first wall 1, and a slot 4 for inserting the insert block 3 is provided on the second wall 2. A first cavity 5 is provided in the second wall 2, and the first cavity 5 is arranged to surround the slot 4. The first cavity 5 is slidably connected to a transversely sliding piston 1 6 and two vertically sliding pistons 2 7, and each piston 1 6 and piston 2 7 is respectively fixed with a piston rod 1 8 and a piston rod 2 9, and the right end of the piston rod 1 8 is located in the slot 4 and is used to contact the insert block 3, and a spring 10 and a spring 2 11 are respectively connected between the piston 1 6 and the piston 2 7 and the inner wall of the first cavity 5, and the two piston rods 2 9 are symmetrically arranged, and a limiting hole 12 for inserting the piston rod 2 9 is provided on the insert block 3, and the limiting hole 12 is vertically arranged. The second wall 2 is provided with an air hole connected to the first cavity 5 and a closing member for closing the air hole. In this embodiment, the closing member is an air hole plug. Opening the air hole plug allows the first cavity 5 to communicate with the outside through the air hole.

[0031] like Fig. 9As shown, the piston rod 9 includes a fixed rod 91 and a movable rod 92, both of which are hollow rods, and the fixed rod 91 and the movable rod 92 are fixedly connected by an elastic member 95, and the elastic member here can be a stainless steel spring. The fixed rod 91 is provided with a first airbag and a second airbag, the left side is the first airbag, and the right side is the second airbag, the first airbag is provided with A glue 93, and the second airbag is provided with B glue 94. The movable rod 92 is provided with a puncture needle 96 for puncturing the first airbag and the second airbag, and the puncture needle 96 is fixed on the mounting rod in the movable rod 92.

[0032] In addition, the movable rod 92 is provided with a liquid outlet 13, and a part of the mixed glue A 93 and glue B 94 can flow out from the liquid outlet, so that the glue has a wider range of action and a better stabilizing effect.

[0033] Initially, spring 10 and spring 2 11 are both in a natural state, and the pore plug closes the pore. When assembling, first place the first wall 1 and the second wall 2 at the same horizontal position, and align the plug 3 with the slot 4 to ensure that the first wall 1 and the second wall 2 are aligned. Then fix the second wall 2, and then push the first wall 1 to the left to approach the second wall 2. In the process of gradually inserting the plug 3 into the slot 4, the plug 3 will abut against the piston rod 1 8 and push the piston rod 1 8, and the piston rod 1 8 will drive the piston 1 6 to slide to the left in the first cavity 5. In the process of the sliding of the piston 1 6, since the piston rod 2 99 has not yet been aligned with the limiting hole 12, the air pressure in the first cavity 5 will continue to increase, and at the same time, the spring 10 will also be deformed by the action of the piston 1 6 and accumulate force. When the piston rod 2 99 is aligned with the limiting hole 12, the piston rod 2 99 will slide quickly into the limiting hole 12 with the piston 2 7 under the action of the air pressure of the first cavity 5, fixing the first wall 1 and the second wall 2. When the piston rod 2 99 slides toward the limiting hole 12 , the spring 2 11 will deform and store force.

[0034] When dismantling, open the air hole plug to connect the first cavity 5 with the outside world through the air hole. The air pressure in the first cavity 5 will be restored. Without the air pressure effect, the piston 2 7 will slide in the opposite direction under the action of the spring 2 11, and drive the piston rod 2 99 to slide in the opposite direction until it is separated from the limiting hole 12. The limiting fixing effect disappears. At this time, you only need to pull out the second wall 2 to separate the first wall 1 from the second wall 2. During the process, the spring 10 will push the piston 1 6 to slide to the right, and the piston 1 6 will drive the piston rod 1 8 to help push away from the second wall 2, so as to facilitate the removal of the wall more conveniently. The entire removal process is quick and convenient, and will not cause damage to the wall, and it is also convenient for the maintenance of the wall in the later stage.

[0035] Generally, the assembled wall needs to be easy to disassemble, but if there is a severe environment such as strong winds or earthquakes, the strength of the wall needs to be strengthened, and disassembly is not the first requirement. At this time, the vibration caused by strong winds or earthquakes will drive the movable rod 92 to move back and forth, and then puncture the first airbag and the second airbag, so that the A glue 93 and the B glue 94 are mixed to fill the gaps in the wall, stick the wall together, and strengthen the strength of the wall.

[0036] Embodiment 2 is basically as shown in the attached Figures 5 to 8 As shown:

[0037] The difference between this embodiment and the first embodiment is that the end of the plug block 3 is wedge-shaped, the end of the piston rod 1 8 is wedge-shaped to match the plug block 3, a second cavity 15 connected to the limiting hole 12 is provided in the plug block 3, a piston 3 16 is slidably connected in the second cavity 15, a spring 3 17 is connected between the piston 3 16 and the plug block 3, a piston rod 3 18 is fixedly connected to the piston 3 16, and a plug hole 21 for the piston rod 3 18 to be inserted is also provided in the slot 4. Each slot 4 corresponds to two first cavities 5, and the two first cavities 5 are symmetrically arranged on both sides of the slot 4. The number of limiting holes 12 is two, and the two limiting holes 12 are symmetrically arranged on both sides of the second cavity 15. A through hole 3 19 is provided on the piston rod 3 18, and a through hole 4 20 connected to the plug hole 21 is provided on the second wall 2. When the piston rod 3 18 is inserted into the plug hole 21, the through hole 3 19 is connected to the through hole 4 20. The through hole three 19 and the through hole four 20 are both threaded and can be tightened by screws to fix the first wall 1 and the second wall 2.

[0038] Initially, spring three 17 is in a natural state. When the insert block 3 is inserted into the slot 4, the wedge-shaped end of the insert block 3 abuts against the wedge-shaped end of the piston rod one 8 and pushes the piston rod one 8 to slide. The piston rod one 8 drives the piston one 6 to slide. Since the piston rod two 9 has not yet aligned with the limiting hole 12, the air pressure in the first cavity 5 will increase when the piston one 6 slides. When the piston rod two 9 is aligned with the limiting hole 12, the piston rod two 9 will slide quickly into the limiting hole 12 with the piston two 7 under the action of the air pressure of the first cavity 5, fixing the first wall 1 and the second wall 2. During the process of the piston rod two 9 being inserted into the limiting hole 12, the piston rod two 9 is in a sealed sliding connection with the inner wall of the limiting hole 12, and the gas in the limiting hole 12 can be pushed into the second cavity 15. The air pressure in the second cavity 15 will push the piston rod three 18 to insert into the insertion hole 21 through the piston three 16, and fix the first wall 1 and the second wall 2 for the second time. After the through hole three 19 is aligned with the through hole four 20, the screw is screwed into them to achieve stable fixation and facilitate disassembly.

[0039] During the whole process, the fixing of the plug block 3 and the slot 4 is performed by two simultaneous forces, namely, the piston rods 9 symmetrically arranged on both sides of the plug block 3 are inserted into the limit holes 12. The two vertical limit settings can improve the fixing effect of the entire wall. In addition, during the process, the piston rod 18 is inserted into the plug block 3 to achieve horizontal limit, further improving the stability of the wall.

[0040] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention. These should also be regarded as the scope of protection of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
