Description

Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, in particular to a building reinforcement type prefabricated structural structure. Background Art

[0002] With the acceleration of urbanization and the continuous development of the construction industry, the safety, durability and economy of buildings have gradually received attention. At present, prefabricated structures are widely used due to their advantages such as fast construction speed, controllable quality and material saving. However, the existing prefabricated structures still have some shortcomings in terms of earthquake resistance, wind resistance, and settlement resistance, especially in the connection between wall components and the stress points of the floor slab.

[0003] When assembling the existing prefabricated walls in the vertical direction, they mainly rely on the reserved steel bars on the top and the prefabricated steel bar sockets on the bottom and are carried out through concrete pouring. During installation, the steel bars of the building components on the lower layer need to be inserted into the steel bar sockets of the building components on the upper layer, and then concrete is grouted into the steel bar sockets and the assembly is completed after solidification. However, this structure is only connected to the upper and lower wall components in the longitudinal direction, and the contact area between the wall and the floor is insufficient. The connection force between the wall and the floor cannot be further improved. After the building is used for a long time, the bottom is prone to cracking. When an earthquake occurs, the upper and lower wall components are easily damaged at the concentrated stress points after being subjected to lateral external forces, resulting in deformation or even collapse of the wall, and the safety hazards cannot be effectively reduced. Summary of the invention

[0004] The object of the present invention is to provide a building reinforcement prefabricated structure to solve the problems raised in the above background technology.

[0006] A plurality of groups of grouting holes are provided on the front and rear end surfaces of the lower part of the prefabricated wall, and each group of grouting holes is connected with the corresponding steel bar insertion holes respectively. A plurality of reinforcing seats are slidably provided on the front and rear sides of the reinforcement base, and a plurality of sleeves corresponding to the grouting holes on the same side of the prefabricated wall are provided on the inner end surfaces of the reinforcing seats on both sides. The reinforcing seats can be moved along the width direction of the reinforcing base to insert the sleeves into the grouting holes, and a plurality of grouting ports which are connected with the sleeves are provided on the outer end surface of at least one side of the reinforcing seat, and the fluid concrete can be injected into the steel bar insertion holes through the grouting ports and flow into the fixing grooves along the through holes to contact the floor slab.

[0007] Furthermore, each of the reinforcement seats includes an L-shaped plate, a clamping block and a number of reinforcement ribs installed on the L-shaped plate at equal intervals, the clamping block is installed on the bottom surface of the L-shaped plate, and a number of clamping grooves corresponding to each clamping block are provided on the front and rear sides of the top surface of the reinforcement base. The L-shaped plate is slidably engaged with the clamping block and the clamping groove to achieve forward and backward movement, and the sleeve is installed on the end surface of the L-shaped plate close to the prefabricated wall.

[0008] Furthermore, the bottom surface of the L-shaped plate is provided with a plurality of threaded holes, and the threaded holes extend through to the bottom surface of the clamping block. The bottom surface of the clamping slot is provided with a plurality of fixing holes corresponding to the threaded holes. Fastening bolts can be screwed into the threaded holes, and the fastening bolts extend through the fixing holes and are inserted into the ground.

[0009] Furthermore, the diameter of the sleeve is smaller than the aperture of the grouting hole, the inner end surface of the reinforcing seat is provided with a plurality of blocking blocks adapted to the size of the grouting hole, the sleeve is assembled on the inner end surface of the blocking block, and the grouting port passes through the blocking block and is connected with the sleeve.

[0010] Furthermore, each group of grouting holes includes upper grouting holes and lower grouting holes distributed up and down, and the upper grouting holes and lower grouting holes extend to communicate with the upper and lower parts of the corresponding steel bar insertion holes respectively, and two adjacent upper grouting holes and lower grouting holes are staggered.

[0011] Furthermore, the outer end surface of each reinforcement seat on the front side is provided with a plurality of grouting openings which are in communication with each sleeve, and the sleeve of the front reinforcement seat is in communication with the sleeve of the rear reinforcement seat on the same vertical plane.

[0012] Furthermore, each edge of the bottom of the fixing groove extends inward to form an edge plate, and positioning holes are opened at the four corners of the reinforcement base. Screws can be screwed into the positioning holes and screwed into preset holes on the ground.

The reinforced base adopts high-strength material and optimized geometric shape, and the pouring of concrete increases the contact area between the wall and the ground, thereby improving the connection force between the wall and the ground, and can effectively resist the action of external forces and reduce the risk of damage to the structure in natural disasters (such as earthquakes, typhoons, etc.).

[0016] The introduction of the reinforced base has a significant effect on the overall stability of the prefabricated wall. Through the auxiliary support design of the reinforced seat that fits the front and rear walls of the prefabricated wall, the force points between the two sides of the wall and the ground are increased, which can effectively share the lateral external force on the wall to the floor, thereby achieving the purpose of reinforced support, improving its strength and seismic resistance, and preventing it from deformation and fracture under vibration.

[0017] The reinforced base and the reinforcing seat thereon in the present invention are both connected and fixed to the wall and the ground by concrete solidification, thereby ensuring that the internal connecting parts are not easy to loosen, achieving the effect of improving stability and having excellent durability.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 4 As shown, a building reinforcement type assembled structure comprises a prefabricated wall 1, wherein a plurality of connecting steel bars 2 are embedded in the prefabricated wall 1, and the ends of the connecting steel bars 2 extend from the top of the prefabricated wall 1, and the bottom of the prefabricated wall 1 is prefabricated with steel bar insertion holes 3 corresponding to the ends of the connecting steel bars 2, and further comprises a reinforcement base 4, wherein the bottom surface of the reinforcement base 4 is provided with a fixing groove 5, and the top surface of the reinforcement base 4 is provided with a plurality of through holes 6 corresponding to the steel bar insertion holes 3, and the ends of the connecting steel bars 2 at the top of the prefabricated wall 1 of the lower layer can pass through the through holes 6 and then be inserted into the steel bar insertion holes 3 at the bottom of the prefabricated wall 1 of the upper layer;

[0026] A plurality of groups of grouting holes 7 are provided on the front and rear end surfaces of the lower part of the prefabricated wall 1, and each group of grouting holes 7 is connected to the corresponding steel bar insertion hole 3 respectively. A plurality of reinforcing seats 8 are slidably provided on the front and rear sides of the reinforcement base 4, and a plurality of sleeves 9 corresponding to the grouting holes 7 on the same side of the prefabricated wall 1 are provided on the inner end surfaces of the reinforcing seats 8 on both sides. The reinforcing seats 8 can be moved along the width direction of the reinforcing base 4 to insert the sleeves 9 into the grouting holes 7, and the outer end surface of the reinforcing seat 8 on at least one side is provided with a plurality of grouting ports 10 intersecting with the sleeves 9. The fluid concrete can be injected into the steel bar insertion hole 3 through the grouting port 10 and flow into the fixing groove 5 along the through hole 6 to contact the floor surface.

[0027] See also Figure 1 , Figure 3 and Figure 5 As shown, each reinforcement seat 8 includes an L-shaped plate 81, a block 82 and a plurality of reinforcement ribs 83 installed on the L-shaped plate 81 at equal intervals. The block 82 is installed on the bottom surface of the L-shaped plate 81. The top surface of the reinforcement base 4 is provided with a plurality of slots 41 corresponding to each of the blocks 82 on both the front and rear sides. The L-shaped plate 81 is slidably engaged with the slots 41 through the blocks 82 thereon to achieve forward and backward movement. The sleeve 9 is installed on the end surface of the L-shaped plate 81 close to the prefabricated wall 1.

[0028] The bottom surface of the L-shaped plate 81 is provided with a plurality of threaded holes 42, which extend through and extend to the bottom surface of the clamping block 82. The bottom surface of the clamping slot 41 is provided with a plurality of fixing holes 43 corresponding to the threaded holes 42. The threaded holes 42 can be screwed with fastening bolts 44, and the fastening bolts 44 extend through the fixing holes 43 and are inserted into the holes preset on the ground.

[0029] The fastening bolts 44 connect the reinforcement seat 8, the reinforcement base 4 and the floor slab into one. On the one hand, they are used to fix the reinforcement seat 8 to prevent it from moving. On the other hand, after the fastening bolts 44 pass through the reinforcement base 4, an unconnected portion will be left in the fixing groove 5. When grouting, the unconnected portion will also be wrapped and filled after the concrete flows into the fixing groove 5. Therefore, after the concrete solidifies, the fastening bolts 44 can be prevented from falling off through this structure. At the same time, the force exerted on the reinforcement seat 8 can be transmitted and shared to the floor slab.

[0030] See also Figure 2 and Figure 3 As shown, the diameter of the sleeve 9 is smaller than the aperture of the grouting hole 7, and the inner end surface of the reinforcing seat 8 is provided with a plurality of blocking blocks 84 that match the size of the grouting hole 7, the sleeve 9 is assembled on the inner end surface of the blocking block 84, and the grouting port 10 penetrates the blocking block 84 and communicates with the sleeve 9;

[0031] Since the diameter of the sleeve 9 is smaller than the aperture of the grouting hole 7, there is a gap between the outer wall of the sleeve 9 and the inner wall of the grouting hole 7. During grouting, concrete will flow into the gap, thereby filling the gap between the sleeve 9 and the grouting hole 7. After the concrete solidifies, the connection force between the sleeve 9 and the grouting hole 7 is increased. The reinforcing seat 8 and the prefabricated wall 1 are connected to form a whole through concrete by embedding the sleeve 9, thereby avoiding horizontal movement of the reinforcing seat 8, so that the reinforcing seat 8 can always maintain a close fit and support with the wall surface of the prefabricated wall 1 after long-term use.

[0032] See also Figure 2 and Figure 3 As shown, each group of grouting holes 7 includes an upper grouting hole 71 and a lower grouting hole 72 distributed up and down, and the upper grouting hole 71 and the lower grouting hole 72 extend to communicate with the upper and lower parts of the corresponding steel bar insertion hole 3, respectively, and the two adjacent upper grouting holes 71 and lower grouting holes 72 are staggered. The outer end surface of each reinforcement seat 8 on the front side is provided with a plurality of grouting ports 10 that are connected with each sleeve 9, and the sleeve 9 of the front reinforcement seat 8 and the sleeve 9 of the rear reinforcement seat 8 on the same vertical plane are in communication.

[0033] See also Figure 3 and Figure 5 As shown, each edge of the bottom of the fixing groove 5 extends inward to form an edge plate 45, and the four corners of the reinforcement base 4 are provided with positioning holes 46, and screws 47 can be screwed into the positioning holes 46 and screwed into the preset holes on the ground;

[0034] The structure extending inward along the plate 45 can, on the one hand, prevent the concrete from overflowing from the gaps in the ground of the reinforcement base 4 during grouting, thereby preventing the waste of concrete, by increasing the contact area with the floor slab. On the other hand, due to the existence of the plate 45, a concave and convex side structure will be formed between the inner wall of the reinforcement base 4 and the ground, which can increase the contact area between the concrete injected into the fixing groove 5 and the inner wall of the reinforcement base 4, thereby increasing the connection force between the two, so as to avoid the problem of cracking of the edge of the reinforcement base 4.

[0035] The working principle of this embodiment is as follows:

[0036] Before the prefabricated wall 1 is assembled, holes corresponding to the positioning holes 46 and the fixing holes 43 are pre-opened on the floor according to the design drawings;

[0037] After the formal assembly, first, according to the pre-opened hole position, insert the through hole 6 of the reinforcement base 4 into the connecting steel bar of the lower building component and then adjust it to the correct position, and screw the screw 47 into the positioning hole 46 until it reaches the ground hole position to complete the positioning and fixing of the reinforcement base 4, and then use large machinery to hoist the prefabricated wall 1 to the top of the reinforcement base 4, and then let the staff guide the bottom end steel bar insertion hole 3 of the prefabricated wall 1 to be inserted into the steel bar end below, and finally slowly fall to the top surface of the reinforcement base 4;

[0038] After the prefabricated wall 1 is in place, the staff will fix and adjust the prefabricated wall 1 by installing oblique supports; after the adjustment is completed, the reinforcing seats 8 on both sides of the reinforcing base 4 are inserted into the card slots 41 of the reinforcing base 4 in turn, and the sleeves 9 are moved inward to be inserted into the grouting holes 7 until the reinforcing base fits the wall of the prefabricated wall 1, and then the fastening bolts 44 are screwed into the threaded holes 42 to complete the fixation of the reinforcing seats 8. At this time, the reinforcing seats 8 and the prefabricated wall 1 form a supporting structure;

[0039] In the final grouting process, concrete slurry is injected from each lower grouting hole 72. The concrete slurry is injected into the steel bar insertion hole 3 along the lower grouting hole 72, and flows into the fixing groove 5 along the through hole 6. After the fixing groove 5 and the steel bar insertion hole 3 are filled, the continuously injected concrete slurry will overflow from the upper grouting hole 71. At this time, the upper grouting hole 71 and the lower grouting hole 72 are sealed to complete the grouting process. Finally, the solidified concrete can connect the fixed base, the connecting steel bars and the prefabricated wall 1 into one.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
