Description

Technical Field

[0001] The utility model belongs to the technical field of connection structures of concrete precast components, and particularly relates to an adjusting structure for connecting concrete precast house components. Background Technique

[0002] In order to improve the construction efficiency of buildings, there are some concrete prefabricated structures in building design, that is, after concrete components are prefabricated in a factory, they are transported to the construction site for assembly.

[0003] The main problem existing in an existing adjusting structure for connecting concrete precast house components is that when connecting the column end to the upper beam, it is necessary to adopt a form of embedded bracket in the upper beam, and guiding holes for bolts to pass through are left on the bracket, while nuts are fixedly embedded at the upper end of the column for bolt fixation. In actual construction, the formwork pre-set in the upper beam will have unevenness problems, resulting in the bracket being installed unevenly. In this way, when performing bolt connection, the tail of the bolt cannot be correctly locked in the nut at the column end, resulting in difficult construction and the need to rework and adjust the formwork cavity. Content of the Utility Model

[0004] The utility model provides an adjusting structure for connecting concrete precast house components, which solves the problems in the prior art.

[0005] The technical solution of the utility model is realized as follows:

[0006] An adjusting structure for connecting concrete precast house components includes a support column, an upper end member and a lower end member fixedly connected to the upper and lower ends of the support column, and a connection structure is arranged between the support column and the connection body;

[0007] The connection structure includes a positioning frame arranged at the upper end of the support column. Adjusting bolts are arranged at two corners on the same side of the positioning frame, and guiding columns are arranged at two corners on the other side;

[0008] A bracket is further arranged at the upper end of the positioning frame. The adjusting bolts abut against the lower end of the bracket, and the guiding columns are inserted into the inside of the bracket. An elastic member is arranged between the guiding columns and the bracket;

[0009] When the adjusting bolts are adjusted, the guiding columns in a diagonal relationship with the adjusting bolts can move inside the bracket, so that the upper end of the bracket is horizontal.

[0010] Further, the bracket is embedded in the upper end member.

[0011] Further, the bracket includes upper and lower plates, and a guiding cylinder arranged between the upper and lower plates. The guiding cylinder is correspondingly provided with guiding holes for bolts, and the guiding cylinder and the upper and lower plates are of an integrally formed structure.

[0012] Further, first raised blocks are also provided at the four corners of the bracket, and second raised blocks corresponding to the first raised blocks are also provided at the four corners of the positioning frame. The adjusting bolts are threadedly connected to the second raised blocks. The lower part of the guiding column is fixedly arranged inside the second raised blocks, while the upper part of the guiding column is movably arranged inside the first raised blocks.

[0013] Further, the elastic member includes an elastic block arranged inside the guiding column. A spring is also arranged between the elastic block and the guiding column. Accommodating grooves are correspondingly formed inside the guiding column and the elastic block, and the elastic block can expand and contract along the accommodating grooves.

[0014] Further, an elastic pad is also arranged between the bracket and the positioning frame.

[0015] Further, a fixing structure is also arranged between the support column and the upper end member. The fixing structure includes a bolt inserted into the bracket and a nut arranged at the upper end of the support column. An anti-loosening member is also arranged between the bolt and the nut. The anti-loosening member is arranged at the upper end of the nut. When the bolt passes through the anti-loosening member, the bolt is locked and fixed by the anti-loosening member, so that the bolt cannot rotate in the reverse direction.

[0016] Further, the anti-loosening member includes a first connecting member arranged on the upper surface of the nut. The end of the first connecting member is connected to a second connecting member. The end of the second connecting member far from the first connecting member is also connected to a third connecting member. When the bolt enters the nut, the third connecting member can be rotated and caught into the thread of the bolt. A limiting member is also fitted along the lower end of the second connecting member, so that the third connecting member cannot rotate in the reverse direction.

[0017] Further, one end of the limiting member is flush with the upturned end of the second connecting member.

[0018] Further, the first connecting member, the third connecting member and the limiting member are all rigid members, and the second connecting member is an elastic member.

[0019] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0020] 1. In the present utility model, by providing the adjusting bolts and the guiding columns, the adjusting bolts and the guiding columns are respectively located on both sides of the support column. When there are uneven places on the bottom surface of the mold cavity in the upper beam, the adjusting bolts are used to adjust the levelness of the upper bracket.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] Embodiment: As Figure 1-2 shown, an adjusting structure for connecting concrete prefabricated housing components includes a support column 30, an upper end piece 10 and a lower end piece 20 fixedly connected to the upper and lower ends of the support column 30, and a connecting structure is provided between the support column 30 and the upper end piece 10;

[0037] Among them, the connecting structure includes a positioning frame 80 arranged at the upper end of the support column 30. A positioning groove for installing the positioning frame 80 is provided at the upper end of the support column 30. The top - view cross - section of the positioning groove is L - shaped, and the positioning grooves at both ends of the support column 30 are inverted and symmetrical to each other. Such a design can prevent the problem that the positioning frame 80 deviates in the front - to - back direction, and can ensure that there is no deviation in the connection and positioning between the positioning frame 80 and the support column 30. Above the positioning frame 80, there is a bracket 40. By adjusting the bracket 40 above the positioning frame 80, since there is no deviation between the positioning frame 80 and the support column 30, when there is no deviation between the positioning frame 80 and the bracket 40, there is also no deviation between the bracket 40 and the support column 30;

[0038] As Figure 3-6 shown, the four corners of the bracket 40 are also provided with first convex blocks 41, and the four corners of the positioning frame 80 are correspondingly provided with second convex blocks 81. Among them, the first convex blocks 41 and the bracket 40, as well as the second convex blocks 81 and the positioning frame 80, are integrally formed. An adjusting bolt 100 is threadedly connected along the inner side of the second convex block 81. The upper end of the adjusting bolt 100 abuts against the lower end of the bracket 40, and a guiding column 90 is provided between the first convex block 41 and the second convex block 81;

[0039] Among them, as Figure 6As shown, the lower part of the guide post 90 is fixedly arranged inside the second raised block 81, while the upper part of the guide post 90 is movably arranged inside the first raised block 41. In addition, an elastic member is arranged between the guide post 90 and the bracket 40, such as Figure 3-4 The elastic member shown includes an elastic block 91 arranged inside the guide post 90. A spring 92 is also arranged between the elastic block 91 and the guide post 90. Accommodating grooves 93 are correspondingly formed inside the guide post 90 and the elastic block 91. The elastic block 91 can expand and contract along the accommodating grooves 93;

[0040] During actual construction, the bottom surface of the mold cavity correspondingly formed between the inner side of the upper end member 10 and the bracket 40 may be uneven. At this time, the adjustment bolts 100 at one or two corners of the uneven part can be turned to adjust the height of one or two corners of the bracket 40. Since the elastic block 91 is arranged on the guide post 90 and the spring 92 is also arranged between the elastic block 91 and the guide post 90, when the adjustment bolts 100 at one or two corners are adjusted, the elastic block 91 on the guide post 90 at the diagonal corner is compressed into the accommodating groove 93, that is, there is a certain adjustable margin between the guide post 90 and the bracket 40, so that the uneven part of the bracket 40 can be adjusted to be flat, ensuring the levelness of the bracket 40. Only after that can the pouring be carried out, so that there will be no deviation between the connecting members during the subsequent connection with the support column 30;

[0041] Such as Figure 2 As shown, an elastic pad 70 is also arranged between the bracket 40 and the positioning frame 80, which can play roles such as shock absorption and buffering;

[0042] Then, the fixed connection between the support column 30 and the upper end member 10 is started. As Figure 1-2 shown, a fixed structure is also arranged between the support column 30 and the upper end member 10. The fixed structure includes a bolt 50 inserted into the bracket 40 and a nut 31 arranged at the upper end of the support column 30. The bracket 40 is embedded in the upper end member 10, and the bracket 40 includes upper and lower plates and a guide cylinder arranged between the upper and lower plates. The guide cylinder is correspondingly provided with a guide hole for the bolt 50. The guide cylinder and the upper and lower plates are of an integrally formed structure;

[0043] During use, the bolt 50 is passed through the guide hole of the bracket 40, and the end of the bolt 50 is threadedly connected to the nut 31 fitted at the upper end of the support column 30 for fixation;

[0044] Such as Figure 7-9As shown, in order to prevent the bolt 50 and the nut 31 in the fixing structure from loosening after long-term use, an anti-loosening member 60 is also provided between the bolt 50 and the nut 31; the anti-loosening member 60 is arranged at the upper end of the nut 31; when the bolt 50 passes through the provided anti-loosening member 60, the anti-loosening member 60 locks and fixes the bolt 50, making the bolt 50 unable to rotate in the reverse direction;

[0045] The anti-loosening member 60 includes a first connecting member 601 arranged on the upper surface of the nut 31. The end of the first connecting member 601 is connected to a second connecting member 603. One end of the second connecting member 603 away from the first connecting member 601 is also connected to a third connecting member 604. In order to ensure that elastic deformation can occur between the first connecting member 601 and the third connecting member 604 when the bolt 50 passes through the nut 31, the second connecting member 603 located between the first connecting member 601 and the third connecting member 604 is an elastic member. At the same time, in order to ensure the overall strength of the anti-loosening member 60, the first connecting member 601 and the third connecting member 604 are set as rigid members. After the bolt 50 and the nut 31 are completely connected, the limiting member 602 can be embedded into the second connecting member 603 to prevent it from undergoing elastic deformation. Similarly, the limiting member 602 is also a rigid member;

[0046] During use, the bolt 50 passes through the nut 31 for threaded connection. At this time, the third connecting member 604 rotates under the pressure of the thread of the bolt 50. When the bolt 50 and the nut 31 are completely fixed, at this time, the limiting member 602 is embedded into the groove pre-opened in the limiting member 602, and the limiting member 602 is knocked in or fixed in the groove in other ways to ensure the fixed connection between the limiting member 602 and the second connecting member 603. Under the action of the limiting member 602, the second connecting member 603 is subjected to pressure, causing the positional relationship between the third connecting member 604 and the thread of the bolt 50 to be as Figure 7 shown. Therefore, if the bolt 50 loosens and wants to rotate in the reverse direction, it will be blocked by the third connecting member 604 and cannot rotate in the reverse direction, ensuring the connection strength between the bolt 50 and the nut 31;

[0047] In addition, as Figure 7 shown, one end of the limiting member 602 is flush with the upturned end of the second connecting member 603, which can prevent the second connecting member 603 from having any remaining deformable margin.

[0048] Working principle: First, it is necessary to position between the support 40 and the positioning frame 80. Since a positioning groove is provided between the upper end of the support column 30 and the positioning frame 80, the positioning frame 80 is inserted into the positioning groove provided in the support column 30 to ensure the positioning between the positioning frame 80 and the support column 30. Then, the support 40 is placed in the mold cavity inside the upper end member 10. The threaded portion of the adjusting bolt 100 is threadedly connected to the second raised block 81, and the upper end of the adjusting bolt 100 is in contact with the lower end surface of the support 40. The upper end of the guide post 90 is inserted into the first raised block 41 of the support 40. After that, a level or other instrument that can measure flatness is used to measure the level of the support 40. When the support 40 is uneven, it is necessary to adjust the adjusting bolt 100 at one or two uneven corners, and turn the adjusting bolt 100 to adjust the height of one or two uneven corners of the support 40. The guide post 90 and the first raised block 41 at the diagonal corner are movably connected, and an elastic block 91 is provided on the guide post 90. A spring 92 is provided between the elastic block 91 and the guide post 90, and there is a margin for extrusion. After the adjustment is completed, pouring is carried out in the mold cavity of the upper end member 10. After waiting for it to be solidified, the support column 30 and the upper end member 10 are fixed. Specifically, the bolt 50 passes through the guide hole of the support 40 and is connected to the nut 31 at the upper end of the support column 30. An anti-loosening member 60 is provided at the upper end of the nut 31. When the bolt 50 passes through the nut 31 for threaded connection, the third connecting member 604 is connected to the second connecting member 603, and the second connecting member 603 is an elastic member. Therefore, under the pressure of the thread of the bolt 50, the third connecting member 604 rotates downward. When the bolt 50 and the nut 31 are completely fixed, since there is still a gap between the support 40 and the support column 30, at this time, the limiting member 602 can be embedded in the groove pre-opened in the second connecting member 603 to ensure the fixed connection between the limiting member 602 and the second connecting member 603. Under the action of the limiting member 602, the second connecting member 603 is under pressure, causing the third connecting member 604 to be stuck on the thread of the bolt 50, and the bolt 50 will be blocked by the third connecting member 604 and cannot rotate in the reverse direction, ensuring the connection strength between the bolt 50 and the nut 31.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
