Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a prestressed concrete building wall. Background Art

[0002] Prestressing refers to applying pre-tensioning stress to the steel bars in the tension module before the engineering structural components are subjected to external loads, thereby increasing the rigidity of the components, delaying the time for cracks to appear, and increasing the durability of the components. Before the structure is subjected to external loads, compressive stress is applied to the tension zone under the action of external loads in advance to improve the performance of the structure. This type of structure is called a prestressed structure. For example, in a concrete structure, applying compressive stress to concrete components in advance can improve the crack resistance and rigidity of concrete components.

[0003] In the existing technology, when encountering a wall that requires prestressed construction during the construction process, a machine is needed to bend the steel bars in the wall. The traditional technology not only requires large machinery such as concrete pouring machines for construction, but also requires waiting for the concrete wall to harden before bending. This makes the wall production cycle long, which is not conducive to the rapid development of subsequent work and slows down the construction pace. Utility Model Content

During the pouring process of the load-bearing wall 5, the steel bars are pre-tensioned to generate prestress. Similarly, the load-bearing beam 3 is prestressed at the same time using the pre-tensioning method. The second tensioned steel bar 32 prestresses the concrete beam 31. The pouring of the column 1 does not use the pre-tensioning method. The prestressed steel bar 15 is wrapped during the pouring of the concrete column 11.

[0018] The bending device 17 includes a fixing sleeve 171, a fixing ring 172 is fixedly connected to the top of the fixing sleeve 171, a welding plate 173 is fixedly connected to the outer wall of the fixing ring 172, a welding steel bar 174 is fixedly connected to the top of the welding plate 173, a force-bearing cylinder 175 is fixedly connected to the top of the welding steel bar 174, the outer wall of the fixing sleeve 171 is fixedly connected to the inner wall of the concrete column 11, the inner wall of the fixing sleeve 171 is fixedly connected to the outer wall of the prestressed steel bar 15, and the top of the prestressed steel bar 15 is fixedly connected to the force-bearing cylinder 175. 5, the load-bearing cylinder 175 converts part of the gravity given by the load-bearing beam 3 and transmits it to the welded steel bar 174, and then transmits the force downward through the welded plate 173. Since the fixing sleeve 171 connects all the welded plates 173 through the fixing ring 172, the bending device 17 forms a whole at this time. At this time, the bending device 17 wraps the top of the prestressed steel bar 15, making the prestressed steel bar 15 easier to bend, and the connection with the load-bearing cylinder 175 is not easy to break.

[0019] The load-bearing beam 3 includes a concrete beam 31, the inner wall of which is fixedly connected with a second tensioning steel bar 32, the inner wall of the concrete beam 31 is fixedly connected with an inclined cylinder 33 through a receiving groove 34, and the receiving groove 34 is opened in the wall of the concrete beam 31, the outer wall of the concrete beam 31 is fixedly connected to the outer wall of the limiting plate 2, the bottom of the concrete beam 31 is fixedly connected to the top of the concrete column 11, and the bottom of the concrete beam 31 is fixedly connected to the top of the load-bearing wall 5. Due to the gravity of the concrete beam 31 itself, the concrete beam 31 carries the inclined cylinder 33 to squeeze the load-bearing cylinder 175, and the contact surface between the inclined cylinder 33 and the load-bearing cylinder 175 decomposes the gravity of the concrete beam 31, and converts a part of it into a thrust moving in the direction away from the load-bearing wall 5.

[0020] Working principle:

[0021] When in use, before building the wall, the load-bearing wall 5, the load-bearing beam 3 and the column 1 are manufactured. During the pouring of the load-bearing wall 5, the steel bars are pre-tensioned to generate prestress, so the first tensioned steel bar 6 is placed in the mold for pouring the load-bearing wall 5 and bent. The prestressing direction is determined according to the bending direction of the steel bars at both ends of the first tensioned steel bar 6. Similarly, the load-bearing beam 3 is prestressed using the pre-tensioning method at the same time, and the second tensioned steel bar 32 prestresses the concrete beam 31. The pouring of the column 1 does not use the pre-tensioning method. The prestressed steel bar 15 is wrapped during the pouring of the concrete column 11, and the concrete column 11 in the limit groove 14 can be used after hardening. , the hardened load-bearing wall 5, the load-bearing beam 3 and the column 1 after pouring can be assembled, the protruding end of the first tensioned steel bar 6 of the load-bearing wall 5 is slid into the positioning groove 13, so as to locate the position of the column 1 and the load-bearing wall 5, and the heat insulation board 4 is installed on the front and rear sides of the load-bearing wall 5, and the heat insulation board 4 is inserted between the columns 1 through the sliding groove 12. Finally, the load-bearing beam 3 is installed, and the load-bearing beam 3 is positioned and fixed by the limiting plate 2 on the column 1, so as to obtain a prestressed wall. The wall obtained by assembling can reduce the time required for wall production, simplify the wall production steps, and make the wall quickly installable because the components can be poured and hardened at the same time.

[0022] The concrete beam 31 installed on the column 1 wraps the bending device 17 inside through the receiving groove 34. At the same time, due to the weight of the concrete beam 31 itself, the concrete beam 31 brings the inclined cylinder 33 to squeeze the load-bearing cylinder 175. The contact surface between the inclined cylinder 33 and the load-bearing cylinder 175 decomposes the weight of the concrete beam 31, and a part of it is converted into a thrust moving in the direction away from the load-bearing wall 5. This thrust pushes the load-bearing cylinder 175, so that the load-bearing cylinder 175 pushes the prestressed steel bar 15. The load-bearing cylinder 175 transfers part of the force to the welded steel bar 174, and transfers the force downward through the welded plate 173. Since the fixing sleeve 171 connects all the welded plates 173 through the fixing ring 172, the bending device 17 forms a whole at this time. At this time, the bending device 17 wraps the top of the prestressed steel bar 15, making the prestressed steel bar 15 easier to bend. At the same time, the connection with the load-bearing cylinder 175 is not easy to break, which prevents the prestressed steel bar 1 5 fails. Since the positioning block 16 and the concrete column 11 fix the bottom position of the prestressed steel bar 15, the bending device 17 bends the end of the prestressed steel bar 15 away from the positioning block 16 at this time, so that the bending direction is aligned with the position of the load-bearing wall 5. Under the weight of the load-bearing beam 3, the load-bearing wall 5 will produce partial deformation and push the columns 1 on both sides. At the same time, in a high temperature environment, concrete will expand under high temperature. The concrete wall prevents heat from entering the load-bearing wall 5 by setting an insulation board 4, and at the same time limits the expansion of the load-bearing wall 5. Since there are no load-bearing objects on the front and back sides of the load-bearing wall 5, even if the insulation board 4 fails and causes expansion, it will not affect the wall. The load-bearing wall 5 expanding to both sides will squeeze the column 1 at this time, which will affect the concrete wall. The load-bearing beam 3 and the bending device 17 cooperate to bend the prestressed steel bar 15, so that the prestressed steel bar 15 generates prestress to resist the thrust generated by the load-bearing wall 5, thereby achieving the purpose of protecting the concrete wall.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
