Description

Technical Field

[0001] The utility model belongs to the technical field of building foundations, and particularly relates to a connection structure for fixing a foundation and a prefabricated wall. Background Technique

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings are processed and manufactured in the factory and transported to the building construction site, and then assembled and installed on-site through a reliable connection method. Prefabricated buildings are more environmentally friendly, more efficient, and have lower costs.

[0003] Currently, prefabricated buildings have been put into use. For example, the Chinese utility model patent with the publication number CN217420019U discloses a prefabricated panel wall and a prefabricated building, specifically including a thermal insulation composite panel and a connection card. The thermal insulation composite panel includes a first board core and first support protection boards glued to the upper and lower surfaces of the first board core. At both opposite ends of the thermal insulation composite panel, the first support protection board has a first extension part extending beyond the first board core to form a first clamping groove. The connection card includes a second board core and second support protection boards glued to the middle parts of the upper and lower surfaces of the second board core. At both opposite ends of the connection card, there is a second clamping groove between the second support protection board and the second board core.

[0004] When installing a prefabricated wall, the foundation needs to be treated first. Only when the foundation is stable can the prefabricated building be more stable. In the prior art, the Chinese invention patent with the publication number CN110528552A discloses a foundation module for a prefabricated house, specifically including a plurality of X crossbeams arranged in parallel, a plurality of Y crossbeams arranged in parallel, and a plurality of ground piles. The X crossbeams and Y crossbeams are vertically and crosswise arranged. A connection plate is provided at the connection of the X crossbeam and the Y crossbeam. Both ends of this plurality of secondary beams are respectively installed and connected to the first side plate or the second side plate of the X crossbeam through a U-shaped plate. A plurality of bolt holes are opened on the base plate of the U-shaped plate. Crossbeam through holes corresponding to the bolt holes on the U-shaped plate are opened on the first side plate and the second side plate of the X crossbeam. Crossbeam nuts are installed on these crossbeam through holes. A bolt passes through the bolt hole on the U-shaped plate and is fixedly connected to the crossbeam nut on the first side plate or the second side plate of the X crossbeam. First connection pieces and second connection pieces are respectively arranged on both sides of the base plate of the U-shaped plate. The first connection piece and the second connection piece are embedded in the secondary beam and installed and connected to the secondary beam. The present invention can further reinforce the foundation structure and improve the stability and strength of the overall foundation structure.

[0031] See Figures 1 to 6, this application provides a connection structure for fixing a foundation and a prefabricated wall, which is detachably connected between the foundation and the prefabricated wall, and includes: an L-shaped connection component 100, a T-shaped connection component 200, and a connection groove 300. The L-shaped connection component 100 includes a first bottom plate 110, a first back plate 130, a first clamping plate 140, and a first core block 150. A plurality of first through holes 120 are provided on the first bottom plate 110, and the first through holes 120 are used to detachably connect the first bottom plate 110 to the foundation. Both the first back plate 130 and the first clamping plate 140 are L-shaped structures and are oppositely arranged on the first bottom plate 110. The first core block 150 is an L-shaped structure and is arranged between the first clamping plate 140 and the first back plate 130. The T-shaped connection component 200 includes a second bottom plate 210, a second back plate 230, a second clamping plate 240, and a second core block 250. A plurality of second through holes 220 are provided on the second bottom plate 210, and the second through holes 220 are used to detachably connect the second bottom plate 210 to the foundation. Both the second back plate 230 and the second clamping plate 240 are arranged on the second bottom plate 210, and two second clamping plates 240 are oppositely arranged to form a T-shaped channel. The second core block 250 is a T-shaped structure and is arranged in the T-shaped channel. The connection groove 300 is detachably connected to one side of the L-shaped connection component 100 or the T-shaped connection component 200.

[0032] Specifically, the prefabricated wall adopts the prefabricated plate wall in the Chinese utility model patent with the publication number of CN217420019U, and the second support protection plate at the bottom of the prefabricated wall extends and protrudes out of the second core plate. Similarly, the connecting pieces for connecting the walls adopt the first connecting piece and the second connecting piece in a prefabricated wall building structure with the publication number of CN220035781U, and the second support protection plate and the third support protection plate of the first connecting piece extend and protrude out of the second plate core, and the third support protection plate and the fourth support protection plate of the second connecting piece extend and protrude out of the third plate core.

[0033] Embedded parts are pre-embedded in the foundation. The reserved positions of the embedded parts are at the corners, the ends of the partitions, and the connecting clamping plates. The embedded parts adopt, but are not limited to, structural forms such as several-shaped steel plates and the combination of steel plates and steel bars with anti-pulling ability and fixed by means of concrete, etc., and screws are welded on the embedded parts. If the foundation is hardened with concrete and there are no embedded parts, the L-shaped connection component 100 and the T-shaped connection component 200 are fixed by means of expansion bolts, etc.

[0034] In the L-shaped connecting component 100 (the first connecting piece in an assembled wall building structure with the publication number CN220035781U), the lengths of the two right-angled sides of the first back plate 130 are both greater than the lengths of the two right-angled sides of the first clamping plate 140, and an L-shaped channel is formed between the first back plate 130 and the first clamping plate 140. The first core block 150 is arranged in the L-shaped channel, and gaps are left between the two sides of the first core block 150 and the first back plate 130 and the second back plate 230 respectively. The width of the gap is the same as the thickness of the second support protection plate, and the height of the second core plate is the same as the length that the second support protection plate extends out of the second core plate. Four first through holes 120 are provided for fixing the first bottom plate 110 to the foundation.

[0035] In the T-shaped connecting component 200 (the second connecting piece in an assembled wall building structure with the publication number CN220035781U), the second back plate 230 is a straight plate, the second clamping plate 240 is an L-shaped plate, and the two L-shaped plates are arranged oppositely and form a T-shaped channel with the second back plate 230. The second core plate is of a T-shaped structure and is arranged in the T-shaped channel. Four second through holes 220 are provided for fixing the second bottom plate 210 to the foundation.

[0036] The connecting groove 300 is made of the same material as the L-shaped connecting component 100 and the T-shaped connecting component 200, and is of a U-shaped groove structure. The connecting groove 300 is detachably connected to the L-shaped connecting component 100 and the T-shaped connecting component 200 by means of, but not limited to, screws, buckles, connecting plates, etc. According to the length and structure of the assembled wall, a plurality of connecting grooves 300, L-shaped connecting components 100 and T-shaped connecting components 200 are provided, and through different combinations, the connection of the assembled wall is realized.

[0037] Further, according to the design drawings, determine the corners of the house, the ends of the partition walls and the connection points of the assembled walls on the leveled concrete foundation. As needed, select the corresponding L-shaped connecting component 100 or T-shaped connecting component 200, and use expansion bolts to pass through the first through holes 120 and the second through holes 220 respectively to fix them to the foundation. Use the connecting groove 300 to connect the L-shaped connecting component 100 or the T-shaped connecting component 200 to form the basic framework of the house. The two sides of the connecting groove 300 are fixed by means of expansion screws or reserved grooves, etc. Install the first connecting piece and the second connecting piece on the L-shaped connecting component 100 and the T-shaped connecting component 200 respectively, and clamp the two ends of the assembled wall on the first connecting piece or the second connecting piece, and the bottom of the assembled wall is clamped in the connecting groove 300.

[0038] The technical solution of the present application adopting the connection structure for fixing the foundation and the assembled wall can achieve the following beneficial effects:

[0039] 1. By setting the L-shaped connecting component 100, the problem of difficult installation at the corner of the prefabricated wall and cumbersome and inconvenient installation is solved.

[0040] 2. By setting the T-shaped connecting component 200, the problem of difficult installation at the partition wall of the prefabricated wall and cumbersome and inconvenient installation is solved.

[0041] 3. By setting the connecting groove 300, the stability of the prefabricated wall is improved, and the installation and removal are simpler and more convenient, and the split setting is convenient for transportation.

[0042] See Figure 1 , preferably, the heights of the first back plate 130 and the first clamping plate 140 are not less than that of the first core block 150.

[0043] Based on the above solution, to improve the stability, a number of third through holes 160 are provided on the first back plate 130 and the first clamping plate 140, and the distance from the third through holes 160 to the first bottom plate 110 is greater than the height of the first core block 150.

[0044] Third through holes 160 are provided at the corresponding positions of the first back plate 130 and the first clamping plate 140, and corresponding holes are provided on the second support protection plate and the third support protection plate that extend and protrude from the second board core. By aligning the third through holes 160 with the holes on the second support protection plate and the third support protection plate and using bolts to fix both sides, the prefabricated wall is fixed together with the first back plate 130 and the first clamping plate 140, thereby improving its stability and being convenient to operate.

[0045] Furthermore, the height of the second core block 250 is the same as that of the first core block 150. The structures of the first connecting piece and the second connecting piece are similar, and the extending lengths of the second support protection plate, the third support protection plate and the fourth support protection plate are the same. When the first connecting piece and the second connecting piece are respectively installed on the L-shaped connecting component 100 and the T-shaped connecting component 200, the first core block 150 fits with the second board core, and the second core block 250 fits with the third board core; by setting the heights of the first core block 150 and the second core block 250 to be the same, the production of the prefabricated wall and the first connecting piece and the second connecting piece is more convenient, the installation is simpler, and the problem of height difference between the first connecting piece and the second connecting piece after installation is solved.

[0046] See Figure 2 , in a preferred implementation manner, the heights of the second back plate 230 and the second clamping plate 240 are not less than that of the second core block 250.

[0047] Specifically, by increasing the height of the second back plate 230 and the second clamping plate 240, the contact area between the third support protection plate, the fourth support protection plate and the second back plate 230 and the second clamping plate 240 is increased, thereby improving the torsional resistance and solving the problem that the prefabricated wall overturns due to accidental loads such as wind and snow.

[0048] In the above solution, in order to improve the stability, a number of fourth through holes 260 are provided on the second back plate 230 and the second clamping plate 240, and the distance between the fourth through holes 260 and the second bottom plate 210 is greater than the height of the second core block 250.

[0049] Specifically, the second back plate 230 is a straight plate, and the length of the second back plate 230 is not less than the sum of the lengths of the right-angled sides of the two second clamping plates 240. Two fourth through holes 260 are provided on the second back plate 230, and one fourth through hole 260 is respectively opened on the right-angled sides of the two second clamping plates 240 parallel to the second back plate 230, and the positions correspond to each other. One fourth through hole 260 with a corresponding position is opened on the two right-angled sides of the two second clamping plates 240 perpendicular to the second back plate 230. By providing the fourth through holes 260, the anti-pulling ability is improved, making it safer.

[0050] See Figure 3 In the optimized solution, first pressing plates 320 and second pressing plates 330 are provided at both ends of the connecting groove 300. The first pressing plates 320 and the second pressing plates 330 are arranged oppositely, and the first pressing plates 320 are detachably connected to the first back plate 130 or the second back plate 230, and the second pressing plates 330 are detachably connected to the first clamping plate 140 or the second clamping plate 240.

[0051] Specifically, the first pressing plates 320 and the second pressing plates 330 are both provided on two side walls of the connecting groove 300. The lengths of the first pressing plates 320 and the second pressing plates 330 extending out of the connecting groove 300 are not greater than the lengths of the right-angled sides of the first clamping plate 140 and the second clamping plate 240. When installing the connecting groove 300, the first pressing plates 320 cover the first back plate 130 or the second back plate 230, and the second pressing plates 330 cover the first clamping plate 140 or the second clamping plate 240, and one end of the connecting groove 300 contacts one end of the first back plate 130 and the first clamping plate 140 or contacts one end of the second back plate 230 and the second clamping plate 240. By providing the first pressing plates 320 and the second pressing plates 330, the connecting groove 300 is detachably connected to the L-shaped connecting component 100 or the T-shaped connecting component 200, making the installation more convenient.

[0052] In the above solution, to improve stability, a convex block 310 is provided in the connection groove 300. The height of the convex block 310 is the same as that of the first core block 150 and the second core block 250. And the convex block 310 and the side wall of the connection groove 300 form a clamping area, which is used for detachably connecting the prefabricated wall. The convex block 310 in the connection groove 300 has the same height as the first core block 150 and the second core block 250. The convex block 310 is strip-shaped and has the same shape as the core board of the prefabricated panel wall. The two sides of the convex block 310 and the two sides of the connection groove 300 form a clamping area, and the width of the clamping area is the same as the thickness of the first support and protection board of the prefabricated panel wall. By providing the convex block 310, a clamping area is formed between it and the connection groove 300, making the installation more convenient and having better stability.

[0053] Further, a number of fifth through holes 340 are provided on the connection groove 300. The distance from the fifth through holes 340 to the bottom of the connection groove 300 is greater than the height of the convex block 310. By providing the fifth through holes 340 and arranging them at equal distances, the prefabricated panel wall with a certain installation thickness has better anti-pulling performance, making it form an integral body with the foundation, thereby improving safety and stability.

[0054] At the connection of two prefabricated panel walls, a type-I connection component 400 can be provided, including a third bottom plate 410, a third back plate 420 and a third clamping plate 430. Both the third clamping plate 430 and the third back plate 420 are straight plates. A type-I third core block 440 is provided between the third clamping plate 430 and the third back plate 420. The first pressing plate 320 covers the third back plate 420, and the second pressing plate 330 covers the third clamping plate 430, and they are fixedly connected by bolts, thereby realizing the connection and fixation of multiple prefabricated panel walls.

[0055] The above embodiments only illustrate the device layout mode of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several adjustments and improvements can still be made, and these all belong to the protection scope of the present application.
