Description
Technical Field
[0001] This application relates to the technical field of lamp socket installation, and particularly to a fixing device for precast laminated slab embedded lamp sockets. Background Art
[0002] A lamp socket refers to an electronic device that fixes the position of a lamp and connects the lamp contacts to a power source.
[0003] Traditional lamp sockets are installed in the wire boxes reserved on the laminated slab. At this time, the lamp sockets can only protrude from the bottom floor slab. Subsequently, in order to embed the lamps into the floor slab to achieve a hidden lighting effect and avoid secondary chiseling operations for installing embedded lamp sockets in the later stage, a construction method of embedding the lamps into the laminated slab has emerged.
[0004] This method is to install the lamp socket on the mold of the laminated slab during the prefabrication process of the laminated slab, and then pour and manufacture the laminated slab. However, during the pouring process of the precast laminated slab, vibration is required to improve the quality of the laminated slab, and during vibration, the position of the lamp socket is likely to move, resulting in the deviation of the position of the embedded lamp socket on the laminated slab. Utility Model Content
[0005] In order to reduce the probability of the position deviation of the embedded lamp socket on the laminated slab, this application provides a fixing device for precast laminated slab embedded lamp sockets.
[0006] A fixing device for precast laminated slab embedded lamp sockets provided by this application adopts the following technical solutions:
[0007] A fixing device for precast laminated slab embedded lamp sockets includes a fixing mechanism arranged on the steel bar keel of the laminated slab for fixing the lamp socket. The fixing mechanism includes:
[0008] A fixing seat, which is arranged on the lamp socket;
[0009] Locking steel bars, which are arranged on the steel bar keel of the laminated slab and clamp and fix the fixing seat;
[0010] A pressing component, which is arranged on the steel bar keel of the laminated slab and presses and fixes one end of the lamp socket.
[0011] By adopting the above technical solutions, the locking steel bars pass through the fixing seat and are fixedly installed on the steel bar keel of the laminated slab. The locking steel bars fix the position of the lamp socket through the fixing seat, and then the pressing component arranged on the steel bar keel of the laminated slab presses the lamp socket, improving the connection stability between the lamp socket and the steel bar keel of the laminated slab, and reducing the probability of the position deviation of the embedded lamp socket on the laminated slab during the vibration process of the laminated slab concrete.
[0012] Furthermore, the fixing base is composed of two groups of fixing blocks, which are respectively arranged on the opposite side walls of the lamp holder. Through holes are formed in the fixing blocks to facilitate the locking steel bars to pass through.
[0013] By adopting the above technical solution, the locking steel bars pass through the through holes and lock the fixing blocks, thereby improving the connection stability between the lamp holder and the laminated slab steel bar keel.
[0014] Furthermore, a locking member for locking the locking steel bars is arranged on the fixing block, and the locking member is used to prevent the locking steel bars from slipping in the through holes.
[0015] By adopting the above technical solution, the locking member locks the locking steel bars on the fixing block, reducing the probability of the lamp holder slipping along the axis direction of the through hole.
[0016] Furthermore, the locking member is a locking bolt threadedly arranged on the fixing block, and the locking bolt moves along a direction perpendicular to the axis of the locking steel bar and abuts against the side wall of the locking steel bar.
[0017] By adopting the above technical solution, after the locking bolt is installed, the locking bolt is screwed, and finally the end face of the locking bolt abuts against the side wall of the locking steel bar to prevent the locking steel bar from slipping in the through hole.
[0018] Furthermore, the laminated slab steel bar keel is arranged on the formwork, and the abutting assembly includes:
[0019] A first abutting steel bar, which is arranged on the laminated slab steel bar keel and abuts and fixes the lamp holder at one end away from the formwork;
[0020] A second abutting steel bar, which is arranged on the laminated slab steel bar keel. The second abutting steel bar intersects with the first abutting steel bar and abuts and fixes one end of the first abutting steel bar away from the lamp holder.
[0021] By adopting the above technical solution, the first abutting steel bar and the second abutting steel bar intersect and abut against the lamp holder, thereby further improving the stability between the lamp holder and the laminated slab steel bar keel.
[0022] Furthermore, multiple groups of rib plates are arranged at intervals on the end of the fixing block away from the formwork, the other ends of the rib plates are arranged on the side wall of the lamp holder, and the locking member is located between two groups of rib plates.
[0023] By adopting the above technical solution, the rib plates improve the stability between the fixing block and the lamp holder.
[0024] Furthermore, transverse ribs are arranged on the locking steel bars, the first abutting steel bars and the second abutting steel bars.
[0025] By adopting the above technical solution, the transverse ribs on the locking steel bars, the first abutting steel bars and the second abutting steel bars enhance the adhesion performance with the concrete.
[0026] Furthermore, a sealing cover is arranged on the lamp holder, and one end of the sealing cover far away from the lamp holder is tightly abutted on the formwork to tightly seal one end of the lamp holder close to the formwork.
[0027] By adopting the above technical solution, the sealing cover seals one end of the lamp holder close to the formwork, and at the same time, the sealing cover is tightly abutted on the formwork and provides a certain supporting force for the lamp holder.
[0028] In summary, the present application includes at least one of the following beneficial technical effects:
[0029] The locking steel bars pass through the fixing seat and are fixedly installed on the laminated slab steel keel. The locking steel bars fix the position of the lamp holder through the fixing seat, and then the first abutting steel bars and the second abutting steel bars tied to the laminated slab steel keel abut one end of the lamp holder far away from the formwork, improving the connection stability between the lamp holder and the laminated slab steel keel, and reducing the probability of the position of the embedded lamp holder on the laminated slab shifting during the vibration of the laminated slab concrete.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0034] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.
[0035] The embodiment of the present application discloses a precast laminated slab embedded lamp holder fixing device.
[0036] Referring to Figure 1 , a precast laminated slab embedded lamp holder 3 fixing device includes a fixing mechanism 4 arranged on the laminated slab steel keel 1 and fixing the lamp holder 3.
[0037] Refer to Figure 1 and Figure 2 ,The laminated slab steel bar keel 1 is fixedly installed on the formwork 2, and the formwork 2 is used for positioning and forming the side wall of the laminated slab. When manufacturing the laminated slab, first complete the binding and installation of the laminated slab steel bar keel 1, and then fix and install the steel bar keel on the formwork 2 through the cushion blocks, so as to complete the preparatory work before pouring the laminated slab.
[0038] Refer to Figure 2 and Figure 3 ,The fixing mechanism 4 includes a fixing seat 5 and a locking steel bar 6. The fixing seat 5 is arranged on the lamp holder 3. The fixing seat 5 is composed of two groups of fixing blocks 51. The two groups of fixing blocks 51 are respectively fixedly installed on the opposite side walls of the lamp holder 3, and the two groups of fixing blocks 51 are symmetrical to each other; a circular through hole 511 is opened on the fixing block 51, and the axis of the through hole 511 is parallel to the plane where the formwork 2 is located.
[0039] Refer to Figure 1 and Figure 2 ,The locking steel bar 6 is arranged on the laminated slab steel bar keel 1 and clamps and fixes the fixing seat 5. There are two groups of locking steel bars 6 and they correspond to the fixing blocks 51 one by one. A sealing cover 9 is snap-fitted and installed at one end of the lamp holder 3 close to the formwork 2. One end of the sealing cover 9 away from the lamp holder 3 abuts against the formwork 2, so as to tightly seal one end of the lamp holder 3 close to the formwork 2 and prevent the concrete from flowing into the interior of the lamp holder 3 when pouring the laminated slab.
[0040] Refer to Figure 1 、 Figure 2 and Figure 3 ,When installing, first snap-fittingly install the sealing cover 9 on the lamp holder 3, pass the lamp holder 3 through the laminated slab steel bar keel 1 and place it on the formwork 2, so that the sealing cover 9 abuts against the formwork 2 for preliminary positioning. Then pass the two groups of locking steel bars 6 through the through holes 511 on the two groups of fixing blocks 51 respectively, and fix the two ends of the locking steel bar 6 on the laminated slab steel bar keel 1 through binding wires, so as to fixedly install the lamp holder 3 on the laminated slab steel bar keel 1.
[0041] Refer to Figure 1 and Figure 3, since the locking steel bar 6 passes through the through hole 511 to fix the lamp holder 3, when vibrating the concrete of the laminated slab, the concrete is likely to drive the lamp holder 3 to slide along the axial direction of the locking steel bar 6. In order to reduce the probability of the lamp holder 3 sliding, a locking member 7 for locking the locking steel bar 6 is provided on the fixing block 51, and the locking member 7 prevents the locking steel bar 6 from sliding in the through hole 511; the locking member 7 of this embodiment is a locking bolt installed on the fixing block 51, and the locking bolt moves along the direction perpendicular to the axial direction of the locking steel bar 6 and abuts against the side wall of the locking steel bar 6. After the locking steel bar 6 is tied to the laminated slab steel keel 1, the locking bolt is turned to tightly fix the locking steel bar 6 on the fixing block 51.
[0042] Refer to Figure 1 and Figure 2 , the fixing mechanism 4 further includes a pressing component 8. The pressing component 8 is arranged on the laminated slab steel keel 1, and the pressing component 8 presses and fixes one end of the lamp holder 3. The pressing component 8 includes a first pressing steel bar 81 and a second pressing steel bar 82. The first pressing steel bar 81 is arranged on the laminated slab steel keel 1, and the first pressing steel bar 81 presses and fixes the lamp holder 3 at the end far from the formwork 2; the second pressing steel bar 82 is arranged on the laminated slab steel keel 1, and the second pressing steel bar 82 intersects with the first pressing steel bar 81, and the second pressing steel bar 82 presses against the end of the first pressing steel bar 81 far from the lamp holder 3; after the lamp holder 3 is locked on the laminated slab steel keel 1 by the locking steel bar 6, the first pressing steel bar 81 is pressed against the end of the lamp holder 3 far from the formwork 2, and then the first pressing steel bar 81 is fixedly tied to the laminated slab steel keel 1 by binding wire, and then the second pressing steel bar 82 is intersectingly pressed against the first pressing steel bar 81, and the first pressing steel bar 81 is moved towards the end close to the lamp holder 3, and finally the second pressing steel bar 82 is fixedly tied to the laminated slab steel keel 1 by binding wire, so as to improve the fixing effect on the lamp holder 3.
[0043] Refer to Figure 1 and Figure 2 , since both the pressing component 8 and the locking steel bar 6 exert forces on the lamp holder 3, it is easy to cause bending between the fixing block 51 and the lamp holder 3. In order to improve the stability between the fixing block 51 and the lamp holder 3, multiple groups of rib plates 52 are installed at intervals on the end of the fixing block 51 far from the formwork 2, and the other side of the rib plates 52 is fixedly installed on the side wall of the lamp holder 3; in this embodiment, two groups of rib plates 52 are provided on the fixing block 51, and the locking bolt is located between the two groups of rib plates 52.
[0044] Refer to Figure 1 and Figure 2, in order to enhance the adhesion performance between the locking steel bar 6, the first abutting steel bar 81, the second abutting steel bar 82 and the concrete, transverse ribs 61 are provided on the locking steel bar 6, the first abutting steel bar 81 and the second abutting steel bar 82. At the same time, the locking bolt abuts against the transverse rib 61 of the locking steel bar 6, further enhancing the locking effect of the locking bolt on the locking steel bar 6; the outer shape of the transverse rib 61 in this embodiment is spiral.
[0045] The working principle of the embodiment of the present application is as follows:
[0046] The locking steel bar 6 passes through the fixing seat 5 and is fixedly installed on the laminated slab steel keel 1. The locking steel bar 6 fixes the position of the lamp holder 3 through the fixing seat 5, and then the first abutting steel bar 81 and the second abutting steel bar 82 tied to the laminated slab steel keel 1 abut against one end of the lamp holder 3 away from the formwork 2, improving the connection stability between the lamp holder 3 and the laminated slab steel keel 1, so that during the vibration of the laminated slab concrete, the probability of the position of the embedded lamp holder 3 on the laminated slab shifting is reduced.
[0047] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
